Testo completoAbstract (sommario):
Human immunodeficiency virus (HIV), hepatitis B virus (HBV) and hepatitis C virus (HCV) are widespread infectious agents. In developed countries, effective therapies have turned potentially lethal HCV, HBV and HIV infections into chronic diseases with a good quality of life, also in terms of reproductive chances. Serodiscordant status is the condition in which only one partner is HIV, HBV and/or HCV positive. In fertile serodiscordant couples, natural conception should be encouraged following specific prophylactic strategies, while infertile serodiscordant couples should be referred for treatment performed using assisted reproduction technology (ART). ART centers working with serodiscordant couples must set up an internal management and control system to guarantee the safety of operators, uninfected patients, gametes and embryos, and also of the fetus, especially during the cryopreservation step. Herein we summarize general features of HIV, HBV and HCV infection, their possible impact on human reproduction, and laboratory recommendations to achieve safe management of serodiscordant couples seeking pregnancy through ART. KEY WORDS: Viral infections, HBV, HCV, HIV, contamination.

ObjectivesThis study describes the burden of the hepatitis B, C and HIV co-infections and assesses associated risk factors.SettingThis analysis used data from a viral hepatitis screening campaign conducted in six districts in Rwanda from April to May 2019. Ten health centres per district were selected according to population size and distance.ParticipantsThe campaign collected information from 156 499 participants (51 496 males and 104 953 females) on sociodemographic, clinical and behavioural characteristics. People who were not Rwandan by nationality or under 15 years old were excluded.Primary and secondary outcomesThe outcomes of interest included chronic hepatitis C virus (HCV) infection, chronic hepatitis B virus (HBV) infection, HIV infection, co-infection HIV/HBV, co-infection HIV/HCV, co-infection HBV/HCV and co-infection HCV/HBV/HIV. Multivariable logistic regressions were used to assess factors associated with HBV, HCV and HIV, mono and co-infections.ResultsOf 156 499 individuals screened, 3465 (2.2%) were hepatitis B surface antigen positive and 83% (2872/3465) of them had detectable HBV desoxy-nucleic acid (HBV DNA). A total of 4382 (2.8%) individuals were positive for antibody-HCV (anti-HCV) and 3163 (72.2%) had detectable HCV ribo-nucleic acid (RNA). Overall, 36 (0.02%) had HBV/HCV co-infection, 153 (0.1%) HBV/HIV co-infection, 238 (0.15%) HCV/HIV co-infection and 3 (0.002%) had triple infection. Scarification or receiving an operation from traditional healer was associated with all infections. Healthcare risk factors—history of surgery or transfusion—were associated with higher likelihood of HIV infection with OR 1.42 (95% CI 1.21 to 1.66) and OR 1.48 (1.29 to 1.70), respectively, while history of physical traumatic assault was associated with a higher likelihood of HIV and HBV/HIV co-infections with OR 1.69 (95% CI 1.51 to 1.88) and OR 1.82 (1.08 to 3.05), respectively.ConclusionsOverall, mono-infections were common and there were differences in significant risk factors associated with various infections. These findings highlight the magnitude of co-infections and differences in underlying risk factors that are important for designing prevention and care programmes.

Introduction: This study was conducted to determine the current molecular prevalence of human immunodeficiency virus (HIV), hepatitis B virus (HBV), hepatitis C virus (HCV), hepatitis D virus (HDV), and human T lymphotropic virus-1/2 (HTLV-1/2) circulating among drug abuser inmates incarcerated in prisons located in Central Java, Indonesia. Methodology: Socio-epidemiological data and blood specimens were collected from 375 drug abuser inmates in four prisons. The blood samples were analyzed with serological and molecular testing for HIV, HBV, HCV, HDV, and HTLV-1/2. Results: The seroprevalence of HIV, HBsAg, HCV, HDV, and HTLV-1/2 in drug abuser inmates was 4.8% (18/375), 3.2% (12/375), 34.1% (128/375), 0% (0/375), and 3.7% (14/375), respectively. No co-infections of HIV and HBV were found. Co-infections of HIV/HCV, HIV/HTLV-1/2, HBV/HCV, HBV/HTLV-1/2, and HCV/HTLV-1/2 were prevalent at rates of 4% (15/375), 1.3% (5/375), 1.1% (4/375), 0.3% (1/375), and 2.1% (8/375), respectively. The HIV/HCV co-infection rate was significantly higher in injection drug users (IDUs) compared to non-IDUs. Triple co-infection of HIV/HCV/HTLV-1/2 was found only in three IDUs (0.8%). HIV CRF01_AE was found to be circulating in the inmates. HBV genotype B3 predominated, followed by C1. Subtypes adw and adr were found. HCV genotype 1a predominated among HCV-infected inmates, followed by 1c, 3k, 3a, 4a, and 1b. All HTLV-1 isolates shared 100% homology with HTLV-1 isolated in Japan, while all of the HTLV-2 isolates were subtype 2a. Conclusion: Drug abuser inmates in prisons may offer a unique community to bridge prevention and control of human blood-borne virus infection to the general community.

Background. This study was aimed at evaluating the seroprevalence and trend of blood-borne pathogens (HIV, HCV, HBV, and Syphilis) among asymptomatic adults at Akwatia during a four-year period (2013–2016). Materials and Methods. The study was a retrospective analysis of secondary data of blood donors who visited the hospital from January 2013 to December 2016. Archival data from 11,436 prospective donors was extracted. Data included age, sex, and place of residence as well as results of infectious markers (HIV, HBV, HCV, and Syphilis). Results. The prevalence of blood-borne pathogens in the donor population was 4.06%, 7.23%, 5.81%, and 10.42% for HIV, HBV, HCV, and Syphilis infections, respectively. A significant decline in HBV and HCV infections was observed in the general donor population and across genders. HIV infection rate remained steady while Syphilis infections recorded a significantly increasing trend, peaking in the year 2015 (14.20%). Age stratification in HBV infection was significant, peaking among age group 40–49 years (8.82%). Conclusion. Asymptomatic blood-borne pathogen burden was high among the adult population in Akwatia. Gender variations in HBV, HCV, and Syphilis infections in the cumulative four-year burden were observed. Awareness needs to be created, especially in the older generation.

<i>Introduction</i>: It has been established that homosexuality plays a considerable role in the persistence of the Human Immunodeficiency Virus (HIV), Hepatitis B Virus (HBV), and Hepatitis C Virus (HCV) infections, but data related to their extent remains paradoxically fragmentary. <i>Objectives</i>: This study aimed to determine the prevalence and determinants of viral infection (Human Immunodeficiency Virus and hepatic viral infections) among homosexuals, bisexuals, and transgenders in Kinshasa, Democratic Republic of the Congo. <i>Methods</i>: Between February 1 and March 30, 2022, an analytical cross-sectional study was conducted among Kinshasa's homosexual, bisexual, and transgender populations. The snowball method was used to choose participants from homosexuals’ organisations. Sociodemographic information and the prevalence of viral infections (HIV, HBV, and HCV) were included as study parameters. The determinants of viral infections were found using multivariate logistic regression. <i>Results</i>: A total of 555 participants (mean age: 28.5±7.8 years, unmarried: 44.9%) were enrolled. Human immunodeficiency virus, hepatitis B, and hepatitis C infection rates were, respectively, 31.5%, 6.3%, and 9.7% prevalent. HIV-HCV, HIV-HBV, and HIV-HBV-HCV coinfection rates were 4.7%, 4.1%, and 0.7%, respectively. HIV and HBV infection had the same risk factors namely piercing, incarceration, prostitution, and non-condom usage. HCV infection was more pronounced among individuals with piercing, STIs and a previous occurrence of jaundice. <i>Conclusion</i>: In Kinshasa, HIV, HBV, and HCV infections were widespread among homosexuals, bisexuals, and transgender people. Actions targeting LBGTs are essential to reduce HIV, HCV and HBV infections transmission in the community.

Testo completoAbstract (sommario):
We analyzed the rate of patients with hepatitis B virus (HBV), hepatitis C virus (HCV), or human immunodeficiency virus (HIV) infection diagnosed by pre-operative screening and estimated its cost. We retrospectively analyzed patients who underwent elective surgery at our maxillofacial surgery department between April 2014 and March 2022. We compared the number of patients with each infection identified by pre-operative screening and a pre-operative questionnaire. We also compared the prevalence of infections with varying age, sex, and oral diseases, and calculated the cost of screening per positive result. The prevalence of HBV, HCV, and HIV was 0.39% (62/15,842), 0.76% (153/15,839), and 0.07% (10/12,745), respectively. The self-reported rates were as follows: HBV, 63.4% (26/41); HCV, 50.4% (62/123); HIV, 87.5% (7/8). Differences in sex were statistically significant for all infectious diseases; age significantly affected HBV and HCV rates. There was no association between the odds ratio of oral disease and viral infections. The cost per positive result was $1873.8, $905.8, and $11,895.3 for HBV, HCV, and HIV, respectively. Although self-assessment using questionnaires is partially effective, it has inadequate screening accuracy. Formulating an auxiliary diagnosis of infectious diseases with oral diseases was challenging. The cost determined was useful for hepatitis, but not HIV.

Testo completoAbstract (sommario):
Infections transmitted by blood are infections where the infectious agent from the blood of one person is transmitted to the other person. These infections usually occur in hospitals and other places of hospitality. A large number of pathogens are transmitted through blood. Except of bacteria and viruses, as the most common pathogens that are transmitted through blood, there has been proven the transfer of the fungus, parasites and spirochetes through blood. Viruses that are the most frequently transmitted through blood and represent the highest risk of infection are: Hepatitis B virus (HBV), hepatitis C virus (HCV) and human immunodeficiency virus (HIV). The primary way to prevent transmission HBV, HCV and HIV in hospitals is to avoid occupational exposure of blood. You need to know that for HBV, HCV and HIV infection exist post exposure prophylaxis (PEP), which refers to a set of measures and procedures which prevent the transmission of pathogens transmitted through blood and other body fluids individuals who are infected.

Blood is a life-saving resource. Despite the significance of blood transfusion in saving a millions life in emergencies and medical treatment, the safety of blood transfusion faced challenges of transmitting life threatening transfusion transmissible infectious agents such as hepatitis B virus (HBV), hepatitis C virus (HCV), and human immunodeficiency virus (HIV). The study was carried out to determine the sero-prevalence of HBV, HCV, HIV and co-infections among blood donors in Ado-Ekiti, Nigeria. A total of five hundred (500) prospective blood donors age ranged from 18 to 60 years attending Ekiti State University Teaching Hospital between May to November, 2019 were recruited for the study. Prospective study was based on questionnaires administered to generate socio-demographics and a 5ml venous blood samples were obtained from each blood donors and the plasma was used for determination of hepatitis B surface antigen (HBsAg) and anti-HCV using immunoassay rapid test kit (RTK) Diaspot, Belgium and HIV-1 and HIV-2 Determine Alere Medical ,Japan and further tested with enzyme linked immunosorbent assay (ELISA) Biorad Monolisa, France). The prevalence of HBV, HCV and HIV were 4.8%, 1.2% and 1.8% respectively, while co-infections with HBV/ HIV and HBV/HCV were 0.2% and 0.2% respectively and there was no case of triple infections among the blood donors. The incidence rate was high in HBV followed by HIV and HCV. The use of RTK and ELISA for screening of blood donor for HBsAg, anti HCV and HIV in terms of their sensitively and specificity showed that ELISA is more sensitive than RTK while RTK is more specific than ELISA. From the retrospective study age and gender distribution was not statistically significant (P > 0.05). A significance difference was observed between married blood donors and HIV infection (P < 0.05) and also blood donors with history of blood transfusion showed statistical significant to HBV and HCV (P < 0.05). The prevalence of HBV, HCV and HIV infections among blood donors were found to be statistically associated with smoking, alcohol consumption, surgical operation, multiple sex partners and tattooing (P < 0.05). This study shows that the prevalence of HBV infection in Ado-Ekiti, Ekiti State ,Nigeria was higher than HCV and HIV, hence there is need to increase public awareness of the socio-cultural practices that contribute to the transmission of infection.

Background: Human immunodeficiency virus (HIV), hepatitis B virus (HBV) and hepatitis C virus (HCV) are the leading causes of death from infectious diseases. Because of sharing same transmission routes, the co-infection of HIV with HBV or HCV is common. And the co-infections make HIV infected persons have higher morbidity and mortality than those who infected only with HIV. This study aims to investigate factors that may have influence on the co-infections of HBV or HCV among HIV positive individuals.Objective: The goals of this study were to identify factors associated with the co-infection of HBV or HCV among people living with HIV. Methods: Quantitative research method was applied in this study to examine factors associated with HBV or HCV co-infection among HIV infected people. A total of 250 HIV infected individuals in Khanh Hoa province, Vietnam were the sample of this study. It employed the Social Ecological Model (SEM) as a theoretical perspective that focused on multiple levels of factors. Descriptive statistic was used to describe the general characteristics of the respondents. And Binary logistic regression was carried out to measure the influence of factors on the co-infection. Results: The multivariate analysis of this study showed that HIV-HBV co-infection was associated significantly with residents of Nha Trang (OR= 7.179). Regarding HIV-HCV co-infection, being men (OR= 7.617), unemployed (OR= 4.013), a resident of Nha Trang (OR=10.894) and an injecting drug user (OR= 16.688) were risk factors of the co-infection.Conclusions: This study recommended that intervention strategies to prevent HIV-positive individuals from co-infection with either HBV or HCV should focuses on altering individuals’ risk behaviors and their socio-economic environments. Also, specific preventing programs should be implemented and focus on unemployed populations, injecting drug users, men in general, as well as people living in particular areas, especially cities having a large number of people living with HIV.

Background/Aims: We report on the rates of hepatitis A virus (HAV), hepatitis B virus (HBV), hepatitis C virus (HCV) and human immunodeficiency virus (HIV) in 1,313 clients entering heroin-assisted treatment (HAT) in Switzerland from 2003 to 2013. We identify predictors of HCV infection. Methods: Data were collected using questionnaires within 2 weeks of clients' first entry into HAT. Prevalence of HAV, HBV, HCV and HIV was calculated using laboratory test results collected at entry or using reports of older test results. Predictors of HCV status were identified through multiple logistic regression analysis. Results: Results show stable rates of HIV-positive clients and decreasing proportions of HAV- and HBV-infected clients. In 2013, there were 12% (n = 8) HIV-, 20% (n = 12) HAV-, 20% (n = 12) HBV- and 52% HCV- (n = 34) positive clients. Vaccination against HAV and HBV had become more frequent. Predictors of positive HCV status included older age, female gender, earlier year of entry, having spent 1 month or more in detention or prison, use of injected heroin and more years of intravenous use. Conclusion: Our results highlight the fact that efforts to prevent and test for infections and to promote vaccination against HAV and HBV in heroin users need to be continued.

Unsterile opioid injection increases risk for infection transmission, including HIV, hepatitis B virus (HBV), or hepatitis C virus (HCV). We assess prevalence of and risk factors associated with opioid overdose and infections with HIV, HBV, or HCV among Medicare beneficiaries with opioid-related fee-for-service claims during 2015. We conducted a cross-sectional analysis to estimate claims for opioid use and overdose and HIV, HBV, or HCV infections, using data from US Medicare fee-for-service claims. Beneficiaries with opioid-related claims had increased odds for HIV (2.3; 95% confidence interval (CI), 2.3–2.4), acute HBV (6.7; 95% CI, 6.3–7.1), chronic HBV (5.0; 95% CI, 4.7–5.4), acute HCV (9.6; 95% CI, 9.2–10.0), and chronic HCV (8.9; 95% CI, 8.7–9.1). Beneficiaries with opioid-related claims and for HIV, HBV, or HCV infection, respectively, had a 1.1–1.9-fold odds for having a claim for opioid overdose. Independent risk factors for opioid overdose and each selected infection outcome included age, sex, race/ethnicity, region, and residence in a high-vulnerability county. Having opioid-related claims and selected demographic attributes were independent, significant risk factors for having HIV, HBV, or HCV claims among US Medicare beneficiaries. These results might help guide interventions intended to reduce incidences of HIV, HCV, and HBV infections among beneficiaries with opioid-related claims.

Co-infection of hepatitis B virus (HBV) and hepatitis C virus (HCV) with human immunodeficiency virus (HIV) is associated with increased risk of hepatic complications and mortality. A retrospective study to estimate the proportion of HBV and HCV co-infections in Singapore was conducted using a clinical database. We included 3065 patients who were seen under the Clinical HIV Programme at the largest referral centre for HIV care between 2006 and 2017 and were tested for both HBV and HCV. Factors associated with HIV-HBV and HIV-HCV co-infections were determined using logistic regressions. The majority (86.3%) of HIV-infected patients were mono-infected, while 7.2% were co-infected with HBV, 6.0% with HCV, and 0.5% were co-infected with both HBV and HCV. The most common HCV genotype was GT1 (63%). Factors significantly associated with HBV co-infection in the multivariable model were: Aged 30–49 years and 50–69 years at HIV diagnosis, male gender, and HIV transmission through intravenous drug use (IDU). Independent factors associated with HCV co-infection were: Malay ethnicity, HIV transmission through IDU, and HIV diagnosis between 2006 and 2008. Behavioural risk factors such as IDU, as well as epidemiologic differences associated with co-infection, should inform further studies and interventions aimed at reducing viral hepatitis infection among HIV-infected individuals.

SUMMARYTo evaluate the prevalence of hepatitis C virus (HCV) and/or hepatitis B virus (HBV) infections in HIV-infected patients in China, an epidemiological serosurvey was conducted from May 2007 to September 2008 using a random cluster sampling design of infectious disease hospitals in seven high HIV-prevalent provinces (municipalities). Univariate analysis and logistic regression were used to study the determinants of HIV and HBV and/or HCV co-infection. The overall prevalence was 41·83% (95% CI 40·36–43·30) for anti-HCV and 12·49% (95% CI 11·50–13·48) for HBsAg, respectively. The prevalence of anti-HCV and HBsAg varied according to the route of HIV transmission. Compared to those with sexually acquired HIV infection, intravenous drug users and blood donors/recipients had the greatest risk of carrying anti-HCV. Needle sharing and unprotected sexual exposures are important modes of transmission for HBV. Further interventions including health education and harm reduction strategies should be implemented in high-risk populations.

Background Blood borne viral infections such as Hepatitis B virus (HBV), Hepatitis C virus (HCV), and Human Immunodeficiency virus (HIV) cause substantial mortality and morbidity worldwide. Viral hepatitis during pregnancy is closely related to high risks of maternal and neonatal complications. In Ethiopia, only a little information is available on co-infection of HCV or HIV among Hepatitis B surface Antigen (HBsAg) positive pregnant mothers. Thus, the study aimed to determine HIV or HCV co-infection and associated risk factors among HBsAg positive delivering mothers. Method A health facility-based cross-sectional study was conducted in five governmental hospitals in Addis Ababa among 265 HBsAg positive delivering mothers in the year 2019 and 2020. A purposive sampling technique was used to select the study participants. Structured questionnaires and laboratory test results were used to collect the data. SPSS version 20 software was used to enter and analyze the data. Multivariable logistic regression was used to identify independent predictors of HIV or HCV co-infections. Results Of the HBsAg positive delivering mothers, 9 (3.4%) and 3 (1.1%) were co-infected with HIV and HCV, respectively. None of them were with triplex infection. All of the socio-demographic characteristics were not significantly associated with both HIV and HCV co-infections. Mothers who had a history of sexually transmitted diseases (STDs) were 9.3 times more likely to have HBV-HIV co-infection (AOR = 9.3; 95% CI: 1.84–47.1). Mothers who had multiple sexual partners were 5.96 times more likely to have HIV co-infection (AOR = 5.96; 95% CI: 1.074–33.104). The odds of having HBV-HIV co-infection were 5.5 times higher among mothers who had a history of sharing shavers, razors, and earrings (AOR = 5.5;95% CI: 1.014–29.69). HCV co-infection was not significantly associated with any of the potential risk factors. Conclusion This dual infection rate of HBsAg positive delivering mother with HIV or HCV indicates that a substantial number of infants born in Ethiopia are at high risk of mother-to-child transmission (MTCT) of HBV, HIV, and HCV. Thus, all pregnant mothers need to be screened for HBV, HCV, and HIV during antenatal care, and also need implementation of prevention mechanisms of MTCT of these viral infections.

With shared routes of transmission, HBV and HCV co-infection are estimated to occur more in subjects with HIV. This study aimed to characterize and describe the prevalence of HBV and HCV co-infections in a cohort of newly diagnosed HIV+ subjects living in China. We conducted a cross-sectional study among newly diagnosed HIV+ subjects aged 18–100 who participated in surveys on the national HIV molecular epidemiology in 2015 and 2023. (The epidemiological table survey is located in the national database alongside serologic testing). The chi-square test was used to identify changes in infections between the studying populations in 2015 and 2023, and conditional logistic regression models were fit to identify risk factors for each co-infection. Among the 11,024 newly diagnosed HIV+ subjects who were surveyed (n = 4501 in 2015; n = 6523 in 2023), the prevalence of HBV, HCV, and HBV/HCV in 2023 was lower than that in 2015, respectively. No decrease was observed in HCV co-infection in men who had sex with men (MSM) in North China, Northeast China, and East China. Increasing recognition among those at high risk of heterosexual transmission and those with low educational backgrounds is paramount to the prevention and control of HIV/HBV/HCV infections.

SUMMARYIncarcerated persons comprise about 0·4% of the Croatian population, of whom 25–30% misuse drugs. We attempted to determine the structure of the prison population, prevalence of HBV, HCV, HIV markers, co-infections with HBV, HCV and HIV and acute HBV, HCV and HIV infection. In total, 25·9% of prisoners were positive for some markers for viral hepatitis (HBV 11·3%, HCV 8·3%, HBV/HCV 6·3%). Prevalence of HBV infection in intravenous drug users (IDUs) was 26·2% (highly promiscuous group 20·4%, individuals with psychiatric diseases and personality disorders 16·0%). HCV infection in IDUs was 52·0% and 4·9% in the highly promiscuous group. HBV/HCV co-infection was registered in 34·9% of prisoners positive for HBV markers (203/582). Acute HBV infection was detected in 0·5%, and HCV in 1·2%. Only 0·15% (5/3348) of prisoners were anti-HIV positive. It appears that individuals with psychiatric diseases and personality disorders could be an additional risk population for these viral infections.

Background and objective: This study was performed to evaluate the prevalence of Hepatitis C virus (HCV) infection as well as HBV, HDV, HTLV I/II, and HIV infection in hemodialysis patients in our district. Methods: The subjects of this study involved 41 hemodialysis patients admitted to hemodialysis ward, Vali- Asr hospital. HBV, HDV, HIV, and HTLV1/2 infections were evaluated by enzyme-linked immunosorbent assay (ELISA) technique. Serum anti- HCV anti-body was measured using the 3rd generation of ELISA kit. HCV Viremia was evaluated in all patients using RT-PCR technique. Results: HCV infection was not observed in none of patients by ELISA technique; however RT-PCR technique demonstrated HCV viremia in one (2.43%) patient. HBsAg was detected in 4(9.75%) patients, and one (2.43%) was Anti HTLV 1/2 positive; none of patients were HDV or HIV positive. Conclusion: HCV infection is less common than HBV infection in our patients. ELISA technique can not demonstrate all hemodialysis patients with HCV infection, For this reason it is requirement to evaluate this group of patients for HCV infection using RT-PC technique.

Background Migrants are not routinely screened for hepatitis B virus (HBV), hepatitis C virus (HCV) and human immunodeficiency virus (HIV) in the Netherlands. We estimated the prevalence and determined factors associated with HBV, HCV and/or HIV infections among undocumented migrants and uninsured legal residents. Methods In this cross-sectional study, undocumented migrants and uninsured legal residents were recruited at a non governmental organization (NGO), healthcare facility in the Netherlands and were invited to be tested for hepatitis B surface antigen (HBsAg), anti-hepatitis B core antibodies (anti-HBcAb), HCV-RNA, and anti-HIV antibodies or HIV antigen at a local laboratory. Results Of the 1376 patients invited, 784 (57%) participated. Participants originated from Africa (35%), Asia (30%) and North/South America (30%). 451/784 (58%) participants went to the laboratory for testing. Of participants 30% were HBV exposed (anti-HBcAb-positive), with 27% (n = 119/438, 95% CI 23.1% to 31.6%) having resolved HBV infection (HBsAg-negative) and 2.5% (n = 11/438, 95%CI 1.3% to 4.5%, 64% new infection) having chronic HBV infection (HBsAg-positive). Compared to HBV non-exposed, HBV exposed individuals were older (p = 0.034) and more often originated from Africa (p<0.001). Prevalence of chronic HCV infection (HCV-RNA-positive) was 0.7% (n = 3/435, 95%CI 0.1% to 2.0%, all new infections) and HIV infection 1.1% (n = 5/439, 95%CI 0.04% to 2.6%, 40% new infection). Conclusion Prevalence of chronic HBV, chronic HCV and HIV infections in our study population is higher compared to the Dutch population, thus emphasizing the importance of case finding for these infections through primary care and public health in this specific group of migrants. Screening uptake could be improved by on-site testing.

Purpose – The purpose of this paper is to evaluate the prevalence of HBV and/or HCV co-infection among HIV-infected inmates entering the correctional facility. Design/methodology/approach – Prospective collection of data of HIV-infected inmates entered the institution over a ten-year period. Findings – During study period 365 consecutive different inmates were evaluated. HCV co-infection was observed in more than 80 per cent of the tested HIV-infected inmates, past HBV infection in 71.6 per cent and active HBV co-infection was detected in 7.1 per cent; triple coinfection (HIV, HCV and HBs-Ag positivity) was present in 6 per cent of the total. Originality/value – This study confirms high prevalence of co-infections among HIV-infected inmates. Testing for HBV and HCV in all HIV-infected inmates at entry in any correctional system is recommended to identify those in need of specific care and/or preventing interventions.

ObjectivesMigrants from high HIV, hepatitis B virus (HBV) or hepatitis C virus (HCV) endemicity regions have a great burden of these infections and related diseases in the host countries. This study aimed to assess the predictive capacity of the Test Rapide d'Orientation Diagnostique (TROD) Screen questionnaire for HIV, HBV and HCV infections among migrants arriving in France.DesignAn observational and multicentre study was conducted among migrants. A self-questionnaire on demographic characteristics, personal medical history and sexual behaviours was completed.SettingThe study was conducted in the centres of the French Office for Immigration and Integration (OFII).ParticipantsConvenience sampling was used to select and recruit adult migrants between January 2017 and March 2020.Outcome measuresParticipants were tested for HIV, HBV and HCV with rapid tests. For each infection, the test performance was assessed using receiver operating characteristics curves, using area under the curve (AUC) as a measure of accuracy.ResultsAmong 21 133 regular migrants seen in OFII centres, 15 343 were included in the study. The participants’ mean age was 35.6 years (SD±11.1). The prevalence (95% CI) of HBV, HCV and HIV was 2.0% (1.8% to 2.2%), 0.3% (0.2% to 0.4%) and 0.3% (0.2% to 0.4%), respectively. Based on the sensitivity–specificity curve analysis, the cut-off points (95% CI) chosen for the risk score were: 2.5 (2.5 to 7.5) for HBV infection in men; 6.5 (0.5 to 6.5) for HBV infection in women; 9.5 (9.5 to 12.5) for HCV infection; and 10.5 (10.0 to 18.5) for HIV infection. Test performance was highest for HIV (AUC=82.15% (95% CI 74.54% to 87.99%)), followed by that for HBV in men (AUC=79.22%, (95% CI 76.18% to 82.26%)), for HBV in women (AUC=78.83 (95% CI 74.54% to 82.10%)) and that for HCV (AUC=75.95% (95% CI 68.58% to 83.32%)).ConclusionThe TROD screen questionnaire showed good overall performance for predicting HIV, HBV and HCV infections among migrants in OFII centres. It could be used to optimise screening for these infections and to propose rapid screening tests to those who are at high risk.Trial registration numberNCT02959684.

The risk of transmission of viral infections in dentistry has caused great public fear both among patients and dentists. This is primarily related to the human immunodeficiency virus (HIV) and hepatitis viruses (HBV and HCV), which can cause many complications. This problem is particularly important in dental practice where the appropriate protection during all dental procedures is required. The application of preventive measures against blood-borne infections (HIV, HBV and HCV) may prevent transmission of these infectious agents during dental intervention. The aim of this study was to emphasize possible ways of transmission and advise prevention and protection measures against HIV, HBV and HCV infections in dental practice.

ObjectivesTo characterise infections by HIV, Treponema pallidum, hepatitis B (HBV) and C virus (HCV) in parturients admitted to Irene Neto Maternity, Lubango city, Huíla province, Angola, namely its seropositivity rate and its association with sociodemographic factors.MethodsAn observational, cross-sectional and analytical facility-based survey was conducted among 500 parturients at Irene Neto Maternity, from October 2016 to September 2017. Women in labour were screened for antibodies against HIV-1/2, T. pallidum and HCV. Antigen detection was used to diagnose HBV infections. Sociodemographic data were also collected. The seropositivity rate and respective CIs were estimated at a level of 95%. Multivariable logistic regression models were performed to explore the association between the studied infections and sociodemographic factors.ResultsIn 11.8% of the parturients (95% CI 9.3 to 14.9), at least one infection was detected. HBV infection was the most common (8.6%), followed by HIV infection (3.0%) and syphilis (1.0%). Coinfection with HBV and HIV was observed in two parturients (0.4%) and HBV, HIV and T. pallidum were all detected in one parturient (0.2%). No HCV infection was detected. For each additional year of formal education, pregnant women had a 10.0% lower chance of being infected with HBV (adjusted OR=0.900, 95% CI 0.816 to 0.992).ConclusionsThis study is one of the few reports contributing for the knowledge of some sexually transmitted infections epidemiology in Angola. The seropositivity rate of the studied infections is of concern, especially the high endemicity of HBV. There is a need for a stronger commitment and further research to design cost-effective public health and clinical interventions to improve the situation.

Background: Transplantation of human corneal tissue is associated with the potential risk of transmittance of viral infections. In accordance with European directives and federal laws, in Germany each tissue donor has to be tested for infectious diseases such as hepatitis B and C virus (HBV and HCV) and human immunodeficiency virus (HIV) infection. However, most of the currently available CE-marked serologic and nucleic acid screening systems are only validated for antemortem blood. Methods: Twenty related and paired ante- and postmortem blood samples from cornea donors were obtained and subsequently analyzed for hepatitis B surface antigen (HBsAg), hepatitis B antibody (anti-HBc), anti-HCV, HCV RNA, anti-HIV-1/2, and HIV p24 Ag using Abbott test systems. The sera were also spiked with reference materials in concentrations giving low and high positivity for HBV, HCV, and HIV markers. Results: The spiked ante- and postmortem sera from related donors showed similar results for HBsAg, anti-HBc, anti-HCV, HCV RNA, anti-HIV, and HIV p24 Ag, indicating a high stability of viral markers in cadaveric specimens. Three cornea donors had a medical history of HBV infection and revealed anti-HBc at similar levels in the ante- and postmortem sera. In addition, there was a single postmortem sample demonstrating a weak signal of anti-HIV-1 and HIV-1 p24 Ag. False-positive or false-negative results were not detected. The results obtained with the Abbott ARCHITECT analyzer and Abbott RealTime HCV PCR showed no significant differences. Conclusion: The analyzed screening assays are suitable for the detection of infectious markers of HBV, HCV, and HIV at similar levels in spiked ante- and postmortem sera from cornea donors.

Testo completoAbstract (sommario):
Background The burden of parallel and overlapping infections of Sexually Transmitted Infections (STIs), particularly HIV, syphilis, hepatitis B (HBV), and hepatitis C virus (HCV) are disproportionately higher among pregnant women globally, leading to unwanted consequences. These infections pose significant public health challenges as they can be transmitted vertically to the offspring. This study aimed to determine the sero-epidemiological patterns and predictors of STIs (HIV, syphilis, HBV, and HCV) among pregnant women attending antenatal care clinics at ten health facilities in North-eastern Ethiopia. Methods An institution-based multi-center cross-sectional study was conducted from May to November 2022 among 422 pregnant women selected using simple random sampling technique. Semi-structured questionnaire was used to collect socio-demographic characteristics and predictor variables of STIs through face-to-face interviews. Venous blood was collected and it was tested for anti-HIV, HBsAg, anti-HCV, and anti-Treponemal antibodies using immunochromatographic test kits. Multinomial logistic regression analysis was used to identify associated factors of STIs. Variables with an adjusted odds ratio (AOR) and a p-value <0.05 were considered statistically significant. Results The overall prevalence of STIs was 23.9% (95% CI = 20.08–28.25). The prevalence of parallel infections of HIV, hepatitis B, hepatitis C, and syphilis were 6.4%, 9%, 1.7%, and 6.9%, respectively. The overlapping infections for HIV-HBV was 4% but HIV-HCV overlapping infection wasn’t found. Increased age, tattooing, multiple sexual partners, exposure to unsafe sex, and RH status were independent factors of HBV. Likewise, increased age, rural residence, illiteracy, and tattooing were independently associated with HCV. Moreover, rural residence and a history of tattooing were independent predictors for the acquisition of HIV, whereas multiple sexual partners and RH status were found to be significant predictors of syphilis infection among pregnant women. Conclusion The magnitude of overlapping and parallel STD infections is still continued to be a problem among pregnant women. Moreover, there were overlapping infections of HBV-HIV. Therefore, continuous screening of pregnant women for HIV, syphilis, hepatitis B, and C infections should be performed, and special attention should be given to pregnant women who have co-infections.

Background. Infections with human immunodeficiency virus (HIV), hepatitis B (HBV), and hepatitis C virus (HCV) are currently major public health problems. Methods. A retrospective study was conducted from January to June 2008 at the Blood Bank of the Central Hospital, Yaoundé (Cameroon). The objective was to study the prevalence of HIV, HBV, and HCV and their coinfections among blood donors. Results. A total of 4650 donors were identified, and the sex ratio (male/female) was 14/1. The median age of donors was 28 years (range: 16 to 69 years). Among blood donors, HBV, HIV, and HCV infection prevalences were 12.14% (n=565) , 4.44% (n=206), and 1.44% (n=67), respectively. Coinfection with HIV and HBV was observed among 0.77% donors, followed by hepatitis B and C co-infection (0.21%) and HIV and HCV coinfection (0.06%). Co-infection with HIV-HBV-HCV was encountered in 2 donors. The HIV, HBV, and HCV infections lead to a destruction of one out of six sets of blood collected. Conclusion. There is a need to review policies for blood collection from donors, by modifying the algorithm of blood donors testing. Pretesting potential donors using rapid tests could help to avoid collection and destruction of (infected) blood.

Abstract Hepatitis B virus (HBV), hepatitis C virus (HCV), and human immunodeficiency virus (HIV) involve similar transmission routes, namely, blood, sexual contact, and mother-baby contact. Therefore, HIV infection is usually accompanied by HBV and HCV infections. This observation poses a great challenge to the prevention and treatment of HIV/human acquired immunodeficiency syndrome (AIDS) accompanied by HBV and HCV infection. Highly active antiretroviral therapy (HAART) has been extensively applied. Hence, liverrelated diseases have become the main causes of complication and death in HIV-infected individuals. This paper summarizes the current epidemiology, mutual influence, and treatment of HIV/AIDS accompanied by HBV or HCV infection.

One of the largest therapeutic problem during the continuous treatment of the patients with Hemophilia A and B, are viral infections as Hepatitis B and C, and HIV, and the other infective diseases, which can be transmitted by the transfusion of blood products.The aim of this study is to analyze the complications of the hemophiliacs in Kosovo which have been treated with fresh frozen plasma, cryoprecipitate and concentrated products of FVIII and FIX. We have tested 75 patients with hemophilia A or B and there were used enzyme immunoassay test-Elisa method for the following: anti-HCV HBsAg, HIV and TPHA.The serological data showed that HCV infection was positive in 29 cases or 38,7%, whereas infection with HBV and HIV were present in a smaller percentage of the patients (2,7% HBV and 1,4% for HIV). HCV infection was present only in 9,5% of the cases of the age group under 18 years. Infected hemophiliacs with one or two infective agents were found in 34,7%, respectively 4%. Infection with T. pallidum was present at none of the examined patients with hemophilia. HCV infection was higher in severe forms of hemophilia B (44,4%), compared with severe form of hemophilia A (30%).Based on our results, despite the infrequent application of FVIII and FIX concentrates, and other anti hemophilic preparations used in treating hemophilia patients, the number of infected hemophiliacs with blood-transmittable infectious agents was substantially high, especially with hepatitis C virus.

Chronic hepatitis negatively affects persons living with HIV. While varying in their transmission efficiency, HIV, HBV, and HCV have shared routes of transmission. Available data suggest widely variable rates of HBV and HCV infections in HIV-infected populations across sub-Saharan Africa. With prolonged survival rates due to increased accessibility to antiretroviral drugs, HBV and HCV have the potential to complicate the prognosis of HIV co-infected patients by contributing significantly to continued morbidity and mortality. The study sought to determine the seroprevalence of HIV/HBV and HIV/HCV co-infections among HIV patients on antiretroviral therapy and to evaluate the effect of HIV/HBV and HIV/HCV co-infections on the immunologic and virologic responses of patients. A cross-sectional study in which samples were taken from 500 people living with HIV and attending ART clinic at the Fevers unit of the Korle Bu Teaching Hospital and tested for Hepatitis B Surface Antigen (HBsAg) and Hepatitis C virus antibody (HCV). CD4 cell counts and HIV-1 RNA levels were estimated as well. Data generated were analysed using IBM SPSS version 22. The seroprevalence of HIV/HBV and HIV/HCV co-infections among people living with HIV was 8.4% and 0.2% respectively. HIV/HBV coinfection included 15/42 (35.7%) males and 27/42 (64.3%) females out of which the majority (97.6%) were in the 21–60 years old bracket. HIV/HBV and HIV/HCV co-infections have varied effects on the immunological and virological response of HIV patients on ART. The mean CD cell count was 361.0 ± 284.0 in HIV/HBV co-infected patients and 473.8 ± 326.7 in HIV mono-infected patients. The mean HIV-1 RNA level was not significantly different (X2 [df] = .057 [1]; P = .811) among HIV/HBV co-infected patients (Log102.9±2.0 copies/mL), compared to that of HIV mono-infected patients (Log102.8±2.1 copies/mL) although HIV mono-infected patients had lower viral load levels. One-third (14/42) of HIV/HBV co-infected patients had virologic failure and the only HIV/HCV co-infected patient showed viral suppression. 336/500 (67.2%) patients had HIV-1 viral suppression (females [66.1%]; males [33.9%]) while 164/500 (32.8%) had virologic failure (females [67.7%]; males [32.3%]). The mean CD4 count of patients with viral suppression and patients with virologic failure was 541.2 cells/μL (95% CI 508.5–573.8) and 309.9 cell/μL (95% CI 261.9–357.9) respectively.The study concludes that, HIV/HBV and HIV/HCV coinfections do not significantly affect the immunologic and virologic responses of patients who have initiated highly active antiretroviral therapy, and treatment outcomes were better in females than in males. There was no HBV/HCV co-infection among patients.

The aim of the study was to assess the prevalence of HCV, HBV, and HIV infections among the patients with hemophilia. Patients with Hemophilia A and B were evaluated who visited hospital for factor replacement therapy. The viral markers tested in these patients included anti-HCV-Ab, HBsAg, and anti-HIV-Ab. Seroprevalence was compared from 5717 exchange healthy blood donors for same markers. A total of 173 multitransfused male hemophiliacs showed prevalence of 51.4% for HCV, 1.73% for HBV, and nil for HIV. In blood donors seroprevalence was 1.9% for HCV, 1.81% for HBV, while no HIV-positive case was detected. Prevalence of anti-HCV-Ab was significantly high in patients with hemophilia than normal donors ( P = .0005). This study showed that HCV infection was more frequently identified than HBV and HIV infections in multitransfused hemophiliacs. The frequency of hepatitis C among blood donors is also higher than that of hepatitis B which is showing downward trend.

The main objective of this study was to evaluate the prevalence of human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS), hepatitis C virus (HCV) and hepatitis B virus (HBV) and their co-infections among people who inject drugs (PWID) and female sex workers (FSWs). Data sources were searched from January 2008 to October 2018 in different databases. Data were analyzed in Stata 16 software using the Metaprop command. The results showed that the prevalence of HIV, HCV and HBV among PWID was 15%, 60% and 6%, respectively. The prevalence of HIV, HCV and HBV among FSWs was 5%, 1% and 3%, respectively. The prevalence of HIV/HCV, HIV/HBV, HCV/HBV and HIV/HCV/HBV co-infections among PWID was 13%, 2%, 3% and 2%, respectively. The prevalence of HIV/HCV and HIV/HBV co-infections among FSWs was 3% and 1%, respectively. The results show that the prevalence of HCV and HIV infections in PWID and the prevalence of HIV in FSWs is higher than their prevalence in the general population. Interventions for the prevention of HIV and HCV in PWID appear to be poor, and may not be sufficient to effectively prevent HIV and HCV transmission.

Background: There are approximately 66 thousand prisoners remained in 68 prisons in Bangladesh. (source: Kara Adhidoptar, Bangladesh). So these number of prisoners suffers from different diseases. Prisoners are associates with various high risk of infectious diseases, as a result of the possibility of transmission of infections in prisons surroundings. A high prevalence of blood borne hepatitis viruses and HIV carried out in correctional facilities around the world by investigations have shown. There are limited data on medical disorders among prison inmates in Bangladesh. The study was aimed at confirming prevalence of HIV, hepatitis B and hepatitis C as well to assess knowledge and attitudes related to HIV, HBV and HCV infections among prisoners admitted to DMCH who referred to medicine department and/ or attended out-patient department in DMCH. Objective: To determine the prevalence and risk factors of HIV, HBV and HCV infection among prisoners referred to tertiary care hospital. Methods: This cross sectional study was done with a total number of 100 inmates over a period of one year. Prisoners, imprisonment for more than six months and who gave consent voluntarily were included in the study. After taking consent from the patient’s/guardians history was taken and physical examination was done. Sample was selected from the population by purposive sampling technique. Data were analysis was done using SPSS version 22.0. Result was expressed in tables and graphs. Results: The results showed a significantly higher seroprevalence of HBV (6%) and HCV (4%) though no prisoner was found to be HIV positive compared to the seroprevalence of these virus infections reported in the general Bangladeshi population (5.8% for HBV and 0.3% for HCV). Exposure of risk factors estimated H/O foreign travels 12%, IV drug abuse 14%, extramarital sexual exposure 16%, sharing of needle 10%, H/O blood transfusion 08%, family H/O diseases 05%, immunization of hepatitis B only 8% and homo sexuality 0%. Risk factors for HBV infection was estimated-family h/o disease 20%, IV drug abuse 7.10%, sharing of needles & syringes 10%, sexual exposue12.50%, blood transfusion 12.50%. Risk factors for HCV infection was estimated -IV drug abuse 7.10%, sexual exposue6.25%, sharing of needles & syringes 20%. Risk factors for HIV infection 0% for all risk factors as no one was HIV infected. Among the IDUs 14% was HBV positive and 30% was HCV positive. Conclusion: The results indicate higher prevalence of HBV and HCV infections among prisoners which has proven that HBV and HCV are the emerging public health problem in a developing country like Bangladesh. Various risk factors contribute to raise prevalence of hepatitis B, hepatitis C and HIV in prisoners. So avoidance from these risk factors is essential to prevent transmission of infection in prison. So health education and dissemination of message about the moods of transmission of these diseases is very important in prison.

Micro RNAs (miRNAs) are essential players in HIV and HCV infections, as both viruses modulate cellular miRNAs and interact with the miRNA-mediated host response. We aim to analyze the miRNA profile of HIV patients with different exposure to HCV to explore specific signatures in the miRNA profile of PBMCs for each type of infection. We massively sequenced small RNAs of PBMCs from 117 HIV+ infected patients: 45 HIV+ patients chronically infected with HCV (HIV/HCV+), 36 HIV+ that spontaneously clarified HCV after acute infection (HIV/HCV-) and 36 HIV+ patients without previous HCV infection (HIV). Thirty-two healthy patients were used as healthy controls (HC). Differential expression analysis showed significantly differentially expressed (SDE) miRNAs in HIV/HCV+ (n = 153), HIV/HCV- (n = 169) and HIV (n = 153) patients. We found putative dysregulated pathways, such as infectious-related and PI3K signaling pathways, common in all contrasts. Specifically, putatively targeted genes involved in antifolate resistance (HIV/HV+), cancer-related pathways (HIV/HCV-) and HIF-signaling (HIV) were identified, among others. Our findings revealed that HCV strongly influences the expression profile of PBMCs from HIV patients through the disruption of its miRNome. Thus, different HCV exposure can be identified by specific miRNA signatures in PBMCs.

Testo completoAbstract (sommario):
The hepatitis delta virus (HDV) is the smallest known human virus, yet it causes great harm to patients co-infected with hepatitis B virus (HBV). As a satellite virus of HBV, HDV requires the surface antigen of HBV (HBsAg) for sufficient viral packaging and spread. The special circumstance of co-infection, albeit only one partner depends on the other, raises many virological, immunological, and pathophysiological questions. In the last years, breakthroughs were made in understanding the adaptive immune response, in particular, virus-specific CD4+ and CD8+ T cells, in self-limited versus persistent HBV/HDV co-infection. Indeed, the mechanisms of CD8+ T cell failure in persistent HBV/HDV co-infection include viral escape and T cell exhaustion, and mimic those in other persistent human viral infections, such as hepatitis C virus (HCV), human immunodeficiency virus (HIV), and HBV mono-infection. However, compared to these larger viruses, the small HDV has perfectly adapted to evade recognition by CD8+ T cells restricted by common human leukocyte antigen (HLA) class I alleles. Furthermore, accelerated progression towards liver cirrhosis in persistent HBV/HDV co-infection was attributed to an increased immune-mediated pathology, either caused by innate pathways initiated by the interferon (IFN) system or triggered by misguided and dysfunctional T cells. These new insights into HDV-specific adaptive immunity will be discussed in this review and put into context with known well-described aspects in HBV, HCV, and HIV infections.

Introduction HIV co-infection with hepatitis B (HIV-HBV) and hepatitis C (HIV-HCV) is known to affect treatment outcomes of antiretroviral therapy (ART); however, its magnitude is not well documented. We aimed to determine the magnitude of HIV-HBV and HIV-HCV co-infections simultaneously in people living with HIV (PLHIV) enrolled in ART care in Addis Ababa. Methods We reviewed the medical records of adults ≥15 years who were receiving ART care in three high burden hospitals in Addis Ababa. Baseline clinical and laboratory test results were extracted from medical records. Co-infection was determined based on hepatitis B surface antigen (HBsAg) and hepatitis C virus antibody (anti-HCV) tests obtained from the medical records. A multivariable logistic regression model was used to identify the risk factors for hepatitis B and C co-infections. Results A total of 873 HIV-positive participants were included in this study. The median age of the participants was 37.5 years, and 55.7% were women. Overall, HIV-HBV co-infection was 5.96% (95% CI: 4.56–7.74), and HIV-HCV co-infection was 1.72% (95% CI: 1.03–2.83). The multivariable logistic regression showed that the male sex was the most independent predictor for viral hepatitis B co-infection with an odds ratio of 2.42(95% CI:1.27–4.63). However, HIV-HCV co-infection did not show a significant association in any of the sociodemographic data of the participants. Conclusion HIV co-infection with hepatitis B was moderately high in individuals enrolled in ART care in Addis Ababa. Men had significantly higher HIV-HBV co-infection. HIV co-infection with hepatitis C was relatively low. Strengthening integrated viral hepatitis services with HIV care and treatment services should be emphasized to improve patient care in health facilities.

In Sub-Saharan Africa, transfusion safety remains a challenge due to the high endemicity of blood-borne infections. This study aimed to determining the seroprevalence of human immunodeficiency virus (HIV), hepatitis B (HBV), hepatitis C (HCV), and Treponema pallidum among blood donors in Ouagadougou. This was a retrospective study in blood donor. HIV 1/2 and HCV antibodies and HBsAg were screened and confirmed with two ELISA (Enzyme Linked ImmunoSorbent Assay). While T. pallidum antibodies were also screened and confirmed with two serology tests. Only samples positive for both tests were counted as positive. Prevalence rates were calculated among first-time blood donors. Of 63,779 registered blood donors, 54,113 (84.84%) were first-time donors. Overall seroprevalences of HIV, HBV, HCV and Treponema pallidum were 2.56%, 11.87%, 5.89% and 3.22% respectively. Seroprevalences of HIV-HBV, HBV-HCV, HBV- T. pallidum and HIV-HBV-HCV co-infections were 0.36; 1.21; 0.54 and 0.02 respectively. The study reports that HIV, HBV, HCV and Treponema pallidum seroprevalences remain high among blood donors. These results highlight a potential infectious risk to blood products recipients.

Background: Hepatitis B virus (HBV), hepatitis C virus (HCV), and Human immunodeficiency virus (HIV) infections are prevalent throughout the world. HIV infection increases the risk of HBV and HCV liver disease especially when HIV-associated immunodeficiency progresses. Aims and Objectives: This study was carried out with the objectives as follows: Estimation of the prevalence of HIV- Hepatitis co-infection, determine CD4+T lymphocyte count in co-infected patients, identify most common opportunistic infections in HIV – Hepatitis co- infection. Materials and Methods: A hospital-based, prospective, cross-sectional, and observational study was carried among people with confirmed HIV infection. HIV antibody, hepatitis B surface antigen (HBsAg), and HCV antibody tests were done in all patients visiting to integrated counseling and testing center. HIV, HBV, and HCV viral load were done in all serologically confirmed patients. In HBsAg positive patients various markers for hepatitis such as hepatitis B envelop antigen (HBeAg), anti-hepatitis B core antibody (HBcAb), and anti-hepatitis B envelop antibody were also done. Results: Out of 357 people living with HIV/AIDS (PLHA) patients 15/357 (4.20%) were co-infected with HBV, 03/357 (0.84%) were co-infected with HCV. The overall seroprevalence of Hepatitis virus (HBV+HCV) in PLHA patients was found to be 5.04% (18/357). CD4+T lymphocyte count <200 cells/μL was seen in 66/339 (19.4%), 04/15 (26.6%), and 03/03 (100%) patients of HIV mono-infected, HBV co-infected, and in HCV co-infected patients, respectively. HIV Viral load ≤1000 copies/mL was seen in 324 and 15 patients in HIV mono-infected and HIV- hepatitis co-infected patient, respectively. Among PLHA patients who were positive for HBsAg; 46.7% (n=7) patients had HBV viral load >2000 IU/mL. All hepatitis B co-infected patients were positive for HBcAb test; HBeAg was positive in 40% (n=06). All HBeAg positive were having viral load >2000 IU/mL. Conclusion: HIV-infected patients are more prone to hepatitis associated liver diseases and exposure to the HBV infection than the general population.

Background The Central African Republic (CAR) is one of the countries with the highest prevalence of viral hepatitis infection in the world. Coinfection with HIV increases the morbidity and mortality beyond that of mono-infection with either hepatitis or HIV. The present study describes the geographic distribution of viral hepatitis infections and molecular characterization of these viruses in the CAR. Methodology Out of 12,599 persons enrolled during the fourth Multiple Indicator Cluster Survey of 2010 in the CAR, 10,621 Dried Blood Spot (DBS) samples were obtained and stored at -20°C. Of these DBS, 4,317 samples were randomly selected to represent all regions of the CAR. Serological tests for hepatitis B, D, and C viruses were performed using the ELISA technique. Molecular characterization was performed to identify strains. Results Of the 4,317 samples included, 53.2% were from men and 46.8% from women. The HBsAg prevalence among participants was 12.9% and that HBc-Ab was 19.7%. The overall prevalence of HCV was 0.6%. Co-infection of HIV/HBV was 1.1% and that of HBV/HDV was 16.6%. A total of 77 HBV, 6 HIV, and 6 HDV strains were successfully sequenced, with 72 HBV (93.5%) strains belonging to genotype E and 5 (6.5%) strains belonging to genotype D. The 6 HDV strains all belonged to clade 1, while 4 recombinants subtype were identified among the 6 strains of HIV. Conclusion Our study found a high prevalence of HBV, HBV/HDV and HBV/HIV co-infection, but a low prevalence of HCV. CAR remains an area of high HBV endemicity. This study’s data and analyses would be useful for establishing an integrated viral hepatitis and HIV surveillance program in the CAR.

Introduction:Studies of the impact of hepatitis C virus (HCV), hepatitis B virus (HBV) and HIV mono and co-infections on the risk of cancer, particularly extra-hepatic cancer, have been limited and inconsistent in their findings.Methods:In the British Columbia Hepatitis Testers Cohort, we assessed the risk of colorectal, liver, and pancreatic cancers in association with HCV, HBV and HIV infection status. Using Fine and Gray adjusted proportional subdistribution hazards models, we assessed the impact of infection status on each cancer, accounting for competing mortality risk. Cancer occurrence was ascertained from the BC Cancer Registry.Results:Among 658,697 individuals tested for the occurrence of all three infections, 1407 colorectal, 1294 liver, and 489 pancreatic cancers were identified. Compared to uninfected individuals, the risk of colorectal cancer was significantly elevated among those with HCV (Hazard ration [HR] 2.99; 95% confidence interval [CI] 2.55–3.51), HBV (HR 2.47; 95% CI 1.85–3.28), and HIV mono-infection (HR 2.30; 95% CI 1.47–3.59), and HCV/HIV co-infection. The risk of liver cancer was significantly elevated among HCV and HBV mono-infected and all co-infected individuals. The risk of pancreatic cancer was significantly elevated among individuals with HCV (HR 2.79; 95% CI 2.01–3.70) and HIV mono-infection (HR 2.82; 95% CI 1.39–5.71), and HCV/HBV co-infection.Discussion/Conclusion:Compared to uninfected individuals, the risk of colorectal, pancreatic and liver cancers was elevated among those with HCV, HBV and/or HIV infection. These findings highlight the need for targeted cancer prevention and diligent clinical monitoring for hepatic and extrahepatic cancers in infected populations.

Introduction The study was carried out to determine the prevalence of and risk factors for hepatitis B and C viral co-infections in HIV infected children in Lagos. Method A cross-sectional study conducted to determine the prevalence and risk factors for hepatitis B and C viral co-infection in children aged 2 months to 13 years. There were 187 HIV infected and 187 HIV naïve age, sex-matched controls. Blood samples of participants were assayed for the serologic markers [HBsAg, anti-HBc, and anti-HCV)] of HBV and HCV viral infections using the Enzyme-Linked Immunosorbent assay (ELISA) method. Result The prevalence of HBV infection using HBsAg was 5.3% and 4.8% (p = 0.814), among HIV-infected and HIV naïve children respectively, while using anti-HBc the prevalence was 7.0% and 7.5% (p = 0.842) among HIV- infected and HIV naïve children respectively. The prevalence of HCV infection among HIV- infected and HIV naive children were equal to 0.5% (p = 1.000). There was also no significant association with the identifiable risk factors (sharing of a toothbrush, sharing of needles, incision marks/tattoo, hepatitis B immunization status, history of blood transfusion, previous surgical operation, sexual exposure/abuse, history of jaundice, and genital circumcision) and the HBV and or HCV status among both groups of children. History of sexual exposure/abuse and history of jaundice were however found to be predictors of the presence of HBsAg among HIV infected children only, using a binary logistic regression model. Conclusion The prevalence of HBV and or HCV infection among HIV-infected children is similar to the prevalence among HIV naïve children, suggesting that HIV-infected children are not more predisposed to viral hepatitis than healthy children. Also, there was no significant difference in the prevalence of HBV infection irrespective of the use of HBsAg or anti-HBc.

The aim of the study was to assess the occurrence of serological and molecular genetic markers of HIV infection, viral hepatitis B and C among persons in pre-trial detention.Materials and methods. The material of the study identified 138 samples of blood sequences obtained from men in the pretrial detention center in St. Petersburg. Patients were examined by ELISA for the presence of serological markers of HIV infection (Ag/Ab HIV), HBV (HBsAg, antiHBs IgG, anti-HBcore IgG) and HCV (anti-HCV IgG). Determination of HIV and HCV RNA, as well as HBV DNA by PCR with hybridization-fluorescence detection in «real time» mode. HBV DNA with a low viral form was detected using a technique developed at the Saint-Petersburg Pasteur Institute.Results and discussion. With the prevalence of the general prevalence of serological markers, markers of HIV infection were detected in 55 (39.86%) patients, HBV — in 73 (52.90%), HCV — in 83 (60.14%). the same markers of HIV infection and HBV were detected in 6 (4.35%) examined, HIV infection and HCV in 17 (12.32%), HBV and HCV in 22 (15.94%) persons, to all three infections in 26 (18.84%) cases. In 22 (15.94%) people did not notice any of the analyzed markers. HIV RNA was found in 23.19%, HCV RNA — in 46.38%, HBV DNA — in 10.14% of the examined. At the same time, HBV DNA with a low viral form (less than 50 IU/ml) was detected in 7.97% of cases, including 6.52% of seronegative samples. Simultaneously, HIV and HCV RNA were detected in 6.52%, HCV RNA and HBV DNA in 2.17% of patients. Molecular biological markers of all three indicators were found in 1.45% of patients. The examined group was ranked by age into the following subgroups: 21– 30 years old (12.32%), 31–40 years old (34.78%), 41–50 years old (37.68%) and older than 51 years old (15.22%). Certain differences in the prevalence and distribution of the analysis of serological and molecular biological markers between age markers, the highest frequency was found for groups of 31–40 and 41–50 years.Conclusion. The results obtained indicate a high prevalence of HIV infections and parenteral viral hepatitis B and C among persons convicted and awaiting a stage in a pre-trial detention center. Careful attention must be paid to their admission to penitentiary institutions, since many convicts are not aware of their morbidity and may become infected. Regular conclusions, concluded in dynamics, including laboratory diagnostics using highly sensitive molecular biological methods, upon admission to a penitentiary institution, and then annually and upon release, should be taken into account as measures to prevent infection with HIV, HBV, HCV.

Aim. Study the role of herpes viruses and pneumocystis in infectious complications in children from HIV-infected mothers. Materials and methods. Sera and blood cells from 59 children from HIV-infected mothers were studied for the presence of various markers of herpes virus infections and pneumocystosis by a complex of methods of modem laboratory diagnostics. Results. Frequency of detection of markers of herpes virus infection was from 10% for chicken pox in children with non-final HIV test to 93% for herpes simplex virus in HIV-infected children from closed organized groups. Signs of active infection in children with laboratory confirmed HIV infection were diagnosed 2.5 times more frequently for HSV infection and chicken pox and 1.8 times more frequently for HHV-6 and pneumocystis than in children with non-final HIV test. Markers of various disease stages with opportunistic infections (01) were detected in children with confirmed HIV-infection: primary acute and latent forms of the infection, reactivation, reconvalescence, whereas in children with non-final HIV test maternal antibodies against herpes virus and pneumocystis predominated. Markers of active infections excluding HSV and HHV-6 were more frequently detected in children from families than in children from closed organized groups. Conclusion. The feature detected - a lower percentage of detection of markers of active forms of 01 in HI V-infected children from social institutions - is determined by the fact that observation of these children is carried out by medical personnel that have the knowledge and experience of prophylaxis of infectious complications in HIV-infected children, whereas quality anti-epidemic regimen is frequently not maintained regarding home children with HIV infection. Another factor facilitating spread of opportunistic infections is the asocial lifestyle of most of the examined families. These data dictate the necessity of enhancement of anti-epidemic regimen and prophylaxis of opportunistic infections in family loci. Not only HIV-infected children, but also all the family members should be examined for markers of herpes virus infection and pneumocystosis in order to detect sources of the infection and timely execution of the prophylaxis measures.

Introduction. Parenteral viral hepatitis (B, C, D) and HIV share modes of transmission and risk groups, in which the probability of infection with two or more of these viruses simultaneously is increased. Mutual worsening of the course of viral infections is important issue that occurs when HIV positive patients are coinfected with parenteral viral hepatitis.
The aim of the study was to determine the prevalence of HCV, HBV and HDV in HIV positive patients in the Novosibirsk region and to give molecular genetic characteristics of their isolates.
Materials and methods. Total 185 blood samples were tested for the presence of total antibodies to HCV, HCV RNA, HBV DNA and HDV RNA. The identified isolates were genotyped by amplification of the NS5B gene fragment for HCV, the polymerase gene for HBV and whole genome for HDV.
Results. The total antibodies to HCV were detected in 51.9% (95% CI: 44.758.9), HCV RNA was detected in 32.9% (95% CI: 26.639.5) of 185 studied samples. The distribution of HCV RNA positive cases completely repeated the distribution of HCV serological markers in different sex and age groups. The number of HCV infected among HIV positive patients increases with age. HCV subgenotypes distribution was as follows: 1b (52.5%), 3а (34.5%), 1а (11.5%), 2а (1.5%). 84.3% of detected HCV 1b isolates had C316N mutation associated with resistance to sofosbuvir and dasabuvir. The prevalence of HBV DNA in the studied samples was 15.2% (95% CI: 10.721.0). M204I mutation associated with resistance to lamivudine and telbivudine was identified in one HBV isolate. Two HDV isolates that belonged to genotype 1 were detected in HIV/HBV coinfected patients.
Conclusion. The data obtained confirm the higher prevalence of infection with parenteral viral hepatitis among people living with HIV in the Novosibirsk region compared to the general population of that region. The genetic diversity of these viruses among HIV infected individuals is similar to that observed in the general population.

Background: Published data on HIV, HBV, and HCV in correctional facilities in Nigeria is scarce. We set out to establish the seroprevalence, co-infection, and risk factors for these infections for the first time among prison inmates in Nasarawa State, Nigeria. Methodology: In a cross-sectional study conducted between April and May, 2007, blood samples were collected from 300 male prisoners of a mean age of 29.2 years, in the state’s four medium-security prisons (overall population: 587). Prior to the study, ethical clearance and informed consent were obtained and structured questionnaires were administered. Samples were analyzed for HIV, HBsAg, and HCV using anti-HIV 1+2-EIA-avicenna, ShantestTM-HBsAg ELISA, and anti-HCV-EIA-avicenna, respectively. Specimens initially reactive for HIV were retested with vironostika microelisa. Data were analyzed using SPSS version 13.0. P values ≤ 0.05 were considered significant. Results: Of the 300 subjects, 54 (18.0 %), 69 (23.0 %), and 37 (12.3 %) tested positive for HIV, HBV, and HCV, respectively. Co-infections were eight (2.7 %) for HIV/HBV and two (0.7 %) for HBV/HCV. Those aged 21-26 years were more likely to be infected with HIV and HBV, while those aged 33-38 years had the highest HCV infection. Associated risk factors included duration in prison, previous incarceration (for HIV, HBV and HCV), intra-prison anal sex, multiple sex partners (for HIV and HBV), ignorance of transmission modes, blood transfusion, and alcohol consumption (for HBV and HCV). No inmate injected drugs. Conclusions: The overall outcome represents the need for prison-focused intervention initiatives in Nigeria. Injected drug use is an unlikely major transmission mode among Nigerian inmates.

Background: End stage renal disease (ESRD) patients undergoing hemodialysis could be at a higher risk of acquiring viral infections such as hepatitis B, C (HBV, HCV) and human immunodeficiency virus (HIV). The study investigated the prevalence of HBV, HCV, HIV and identified the determinants of these viral infections among end stage renal disease (ESRD) patients undergoing hemodialysis at the Cape Coast Teaching Hospital (CCTH). Methods: This retrospective hospital-based record review was conducted at the CCTH among 89 patients who underwent hemodialysis in at the renal unit of the hospital. The viral infection histories of all the recruited patients were collected as well as clinical and demographic data to identify the determinants of viral infections. Results: Of the 89 patients comprising of 59 (66.3%) males and 30 (33.7%) females, 11(12.4%) were found to be positive for HbsAg, and 6 (6.7%) were found to be positive for HCV infection. Five (5.6%) patients were positive for HIV and 5 (5.6%) participants had co-infection of HBV and HCV. No co-infection of the three viral infections was reported among the participants. Of the various parameters assessed, only average monthly dialysis sessions varied significantly by gender. Univariate logistics regression analysis indicated that HCV [OR=64.17; 95% CI (6.42-641.41) p<0.001] and HBV [OR=35.45; 95% CI (3.78-332.35) p=0.002] infection was a significant independent risk factor of acquiring HBV and HCV infection respectively. The commonest causes of ESRD among participants were hypertension (54.5%) and chronic glomerulonephritis (27.3%). Conclusion: Prevalence rates of the three viral infections studied were high. The likelihood of getting infected with one viral agent as a result of an already existing viral agent was significant. There is therefore an urgent need for the intensification of health education on the occurrence so as to help curb a possible escalation of the viral infection in the general population.

Abstract Abstract: This paper shows the results of a retrospective observational analytical study that has enrolled 166 HIV positive patients diagnosed with a neurological complication between June 2012 and June 2020, in Clinical Infectious Diseases Hospital of Constanta. 119 patients (71,69%) were diagnosed with one of the three neurological complications: HIV associated dementia (HAD), Progressive Multifocal Leukoencephalopathy (PML) and CNS Toxoplasmosis (CT). We have noted CD4 levels, viral loads, and the presence/absence of other infections like: HBV, HCV, Treponema pallidum, Mycobacterium Tuberculosis. The results show that PML and CT, in this order, are the main opportunistic infections with important neurological impact. Both, PML and CT are in direct correlation with the immune status, but also with other infections like the infection with HCV or with M. Tuberculosis. CD4 nadir <100 cells/mmc and viral load ≥100000copies/ml have a stronger association with PML (p<0,05). Patients known with HIV and T. pallidum infection are more likely, in case of new sudden neurological signs, to be diagnosed with Neurotoxoplasmosis versus PML, or HAD (p<0,05). Given the fact that HIV patients can have multiple alterations of neurological functions, and spectaculous but complicated neuro imagistic results, knowing the history of the patients, the lab results, and the statistical probability can help the physician, infectious disease specialist or neurologist, to make a faster and precise diagnosis.

BackgroundHIV, Hepatitis B Virus (HBV) and Hepatitis C Virus (HCV) are life threatening viral infections. Co-infections are possible since they share routes of transmission through exchange of blood/body fluids. Youths are the most vulnerable to HIV infection due to unsafe practices. There is no free counselling and testing for HBV/HCV in Nigeria, hence many may not be aware of their HBV/HCV status. This study assessed prevalence, knowledge and risk factors of transmission among University students in order to provide preventive intervention.MethodsPreviously counselled/consenting university students (total=903, M=502, F=428; age range 16–40 years; mean age 19 years) were enrolled. Relevant information was collected through questionnaire. About 5 ml of blood was collected from each student and serum recovered was analysed for detectable HIV antigens/antibodies using specific ELISA kit. HIV antigen/antibody-positives were analysed for detectable hepatitis B surface antigen and anti-HCV. The HIV and HBV-positives were compared in terms of gender, age group, and risk factors by use of chi-square and Fischer exact tests, with two-tailed significance using SPSS version 20.0.1 for Windows.ResultOf the 930 students examined, 630 (67.7%) were sexually active and 104 (16.5%) had multiple sex partners. Knowledge of HIV, HBV and HCV status was 55%, 36.3% and 4.2% respectively. Overall, 13 (1.40%) students had detectable HIV antigens and/or antibodies, 5 (38.5%) of whom were HBV-positive, none had HCV infection. All HBV-positive students were ignorant of their HBV status. HIV and HBV-positive students fall within age range 15–24 years with higher HIV/HBV prevalence in females than males. Statistical significance exists between HIV, HBV prevalence and a) gender, b) number of sex partners, and c) sharing sharps with people of unknown HIV/HBV status (p=0.005; 0.002 and 0.005, respectively).ConclusionKnowledge about HBV and HCV is generally low among the students. Awareness campaigns specifically tailored towards educating young adults on HIV, HBV and HCV prevention/control should be encouraged.

Background: Hemodialysis [HD] patients are more prone to blood-borne viruses, such as hepatitis B virus [HBV], hepatitis C virus [HCV], and, to a lesser extent, Human Immunodeficiency Virus [HIV]. Chronic HBV and HCV infections are associated with liver cirrhosis, hepatocellular carcinoma, and early graft failure after kidney transplantation. As there was no recent information, this study aimed to evaluate the prevalence of HBV, HCV, and HIV infection in HD patients in Fars province, southern Iran. This could help health policymakers to run more effective infection control practices for reducing such blood-borne virus infections, if necessary. Methods: This cross-sectional study was performed on 906 HD patients in Fars province, southern Iran. A total of 906 blood samples were obtained from patients and diagnostic tests of HBV, HCV, and HIV were done. Demographic data and some other information, such as duration of dialysis, were extracted from the patients’ medical records. Data were analyzed in SPSS, version 18. Results: Out of the patients enrolled in the study, 547 [60.4%] were male and 359 [39.6%] female. The mean ± SD age of the patients was 58.0 ± 15.8 years. The prevalence of HBV, HCV, and HIV infection was 0.88%, 0.55% and 0.44%, respectively. HIV-infected subjects were significantly younger than the HIV-negative group [P <0.017]. Conclusion: It seems that Fars is among the provinces with low HBV and HCV prevalence in HD patients in comparison to other provinces of Iran. On the other hand, HIV prevalence here is higher than other provincial studies. Strict adherence to preventive infection control measures is recommended in HD centers.

Aims: The study aimed at determining the epidemiological feature and burden of infectious markers among asymptomatic adult population in Koforidua. Methods: This is a hospital-based retrospective study conducted at the Eastern Regional Hospital and comprised of a review of secondary data of prospective blood donors who visited the facility blood bank from January 2015 to December 2020. Archived data of 22,648 prospective blood donors comprising gender, age, and residential locations as well as results of infectious markers [syphilis, hepatitis C virus (HCV), hepatitis B virus (HBV), and human immunodeficiency virus (HIV)] were retrieved from the blood bank. Prospective blood donors were screened for infectious markers using rapid diagnostic test (RDT) kits. Hepatitis B, hepatitis C, and syphilis were screened using Abon, Micropoint, Just check, Green life, and Accurate rapid diagnostic test kits whereas HIV was screened using First response kits. Results: The overall cumulative crude prevalence rate of blood-borne pathogens was 69.76 per 10,000, 27.45 per 10,000, 115.15 per 10,000, and 33.87 per 10,000 population for HBV, HCV, syphilis, and HIV, respectively. A prominent year-on-year decreasing trend of hepatitis B viral infection and HIV was observed in the general population. On the other hand, syphilis infection recorded an increasing trend of infection while HCV infection demonstrated a dual trend with a decrease from 2016 to 2018 and an increase till the end of 2020. Conclusion: The overall burden of transfusion transmissible infections (TTIs) was high among the populace with a prominent male gender preponderance. The rates of the infections were highly marked among the youth population within the ages of 20 to 29 years.

Background: Human immunodeficiency virus (HIV) positive population is at higher risk of getting infected with hepatitis B virus (HBV) or hepatitis C virus (HCV) or both. Co-infection with HBV/HCV may possibly complicate the clinical course of HIV in infected patients. Aim and objectives of the study were intended to determine clinical, haematological and biochemical profile of HIV patients co infected with hepatitis B and/or C.Methods: All consecutive patients presented with HIV infection who were coinfected with either Hepatitis B, C or both presenting to immunodeficiency or Gastroenterology OPD Base Hospital Delhi, were included in the study. It was a prospective, observational study.Results: HIV impacts the progression of HCV and increases the likelihood of subsequent liver damage as it is apparent in study by significant raised liver enzymes and hypoalbuminemia in HIV-HCV co infection compare to HIV–HBV. Conclusions: These coinfections are more common in younger and lesser educated people. Biochemical parameters could serve as pointers for early detection of liver disease as result of hepatitis co infections in HIV patients. Prompt diagnosis of HCV and HBV co-infection in HIV patients has both individual and public health benefits.
