Hospital-acquired infections and bacterial resistance to antibiotics are widespread worldwide, with a higher prevalence in developing countries with limited resources, including Lebanon. In Lebanon, epidemiological data on resistance among Gram-negative bacteria to antibiotics of last resort in hospitals and on nosocomial infections are scarce. Aims: We conducted three studies to meet the following objectives: a first study to identify and compare the different bacteria identified in communityacquired infections and nosocomial infections, focusing on associated co-morbidities and sociodemographic factors. This was followed by two studies targeting resistance to last-resort antibiotics in Gram-negative bacilli, in order to describe the epidemiology and identify patient characteristics associated with this resistance. Mortality in patients with Gram-negative bacilli resistant to carbapenems was analyzed. Methods. The first study was a retrospective, multicenter cohort study conducted in five hospitals. Data were collected using a standardized form (demographic data: gender and age, underlying diseases and type of acquired infection). The other two studies were based on a prospective cohort study using a database compiled in nine Lebanese hospitals between 2016 and 2017 (patient characteristics, variables related to hospitalization and variables related to the characteristics of the infection). Data were collected and processed using Statistical Package for the Social Sciences SPSS version 24. Logistic regressions were used to define the profile of patients for each type of resistance (3rd generation cephalosporins-3GC, fluoroquinolones, aminoglycosides, carbapenem) observed in Gram-negative bacilli (Enterobacteria, Pseudomonas aeruginosa and Acinetobacter baumannii). A sensitivity analysis based on the extreme results of the missing values for bacterial sensitivity was used to take account of the missing data and provide robust results. Results. The first study showed the importance of Gram-negative bacilli resistant to antibiotics in both hospital and community-acquired infections, with two independent factors in the acquisition of a nosocomial infection: advanced age and immunosuppression. The other two studies showed high percentages of resistance in the targeted Gram-negative bacilli and established different patient profiles for each type of resistance. For example, in Escherichia coli, resistance to 3GC was associated with previous hospital admission and the presence of a urinary catheter. Similarly, resistance to carbapenems in Gram-negative bacilli was associated with surgical patients, the presence of a urinary catheter, and pulmonary or surgical site infection. In terms of overall mortality, the Cox proportional model showed that carbapenem resistance was associated with a significant difference in hospital survival in patients with nonfermenting gram-negative bacilli compared with susceptible bacteria. Conclusions. We report on resistance to antibiotics of last resort in enterobacteria (E. coli and Non-E. coli enterobacterales) and non-fermenting Gram-negative bacilli identified in Lebanese hospitals, where epidemiological data are scarce. Describing the profiles of patients carrying these resistant bacterial strains will enable clinicians to prescribe appropriate probabilistic antibiotic therapy

Infections due to multidrug-resistant gram-negative bacteria especially the resistance to carbapenems, have become a major public health problem. This increase in resistance to antibiotics has led to the resuscitation of colistin, as a last-resort treatment option. Our PhD work focused on the epidemiological study of the antibiotic resistance of clinical isolates in Lebanon. This thesis is divided into 5 chapters with three main objectives; (1) the investigation of carbapenem-resistant bacteria in Lebanese hospitals. (2) the Elucidation of the molecular mechanisms of colistin-resistant bacteria in Lebanese patients, and (3) the emergence of vancomycin-resistant gram-positive bacteria in Lebanon. At the start of this thesis, we have prepared a literature review on the epidemiology and the risk factors associated with bacterial infection in conflict wounded and natural disaster in Asia and the Middle East. The second chapter aimed to see the effect of the shift of treatment from colistin-carbapenem combination to colistin monotherapy on the prevalence and resistance of A. baumannii, in addition to the detection of the plasmid-encoded blaVIM-2 gene. In the third chapter, we have detected the spread of colistin-resistant gram-negative bacteria due to mutation of the two-component systems (pmrA /pmrB, phoP/phoQ), or mgrB. We detect the emergence of vanA of Enterococcus faecium resistant to vancomycin. This observation confirms that colistin resistance in Gram-negative bacteria is indeed increasing. In conclusion, it appears necessary and urgent to set up surveys to monitor the use of antibiotics to prevent the spread of resistant strains in Lebanon

Antimicrobial resistance is a major heath problem, especially in hospital-acquired infections. Many epidemiological data showed an association between antibiotic use and infection caused by antibiotic-resistant bacteria. To assess the impact of antibiotic use and other factors, we performed two epidemiological studies on clinical Escherichia coli strains isolated from hospital patients. We showed a significant association between antibiotic use and immunosuppression and infection caused by resistant E. Coli. Previous use of β-lactamine was associated with amoxicillin- and third generation cephalosporin resistance, and previous use of fluoroquinolones and cotrimoxazole was associated with strains resistant to those antibiotics. In a second time, we performed a prospective study of the gut flora of 933 patients hospitalised in five different wards, including medicine and surgery wards and intensive-care units. No vancomycin-resistant Enterococci was isolated. 585 patients were colonised by an amoxicillin-resistant Enterobacteriaceae, with third generation cephalosporin- and ofloxacin resistance rates of 9. 4% and 4. 8%, respectively. One hundred and ninety five patients were colonized by Pseudomonas aeruginosa (23% on admission). Antibiotic use was implicated in all observed resistances. Previous hospital stay and hospitalisation in specific wards were also associated with antibiotic resistance. Studies of intestinal microflora are difficult to perform but are useful in epidemic situations and in target resistance surveillance programs

Considered as a silent pandemic, antimicrobial resistance (AMR) is a major public health issue, that, combined with hospital-acquired infections (HAIs) threaten the quality and safety of hospital care. Monitoring antibiotic resistance and nosocomial infections is one of the cornerstones of preventing these phenomena. Surveillance programs are key in bringing a comprehensive knowledge of the current situation, essential for an effective implementation of prevention strategies. Surveillance of these phenomena can also be used for comparisons between facilities if we take care to take into account other factors of importance such as antibiotic and alcohol-based hand rub consumptions, and individual patient data.This thesis was conducted at the Assistance Publique - Hôpitaux de Paris (AP-HP), Europe's largest university hospital centre, during the COVID-19 pandemic. The significant rise in intensive care activities and antibiotic consumption has prompted us to redirect our objectives to assess the COVID-19 impacts on HAIs and AMR in our hospitals. Our study focused on bloodstream infections, by using data on blood cultures, collected from AP-HP bacteriology laboratories.We have demonstrated that this period was accompanied not only by an increase in the incidence of bacteraemia, but also in AMR among Enterobacteriales.Of interest, we have observed a decrease in invasive infections induced by Streptococcus pneumoniae and Streptococcus pyogenes, bacterial types which transmission can be controlled by wearing a mask.A review of a carbapenemase-producing Enterobacteriaceae (CPE) outbreak in an intensive care unit heavily impacted by the pandemic completes these studies.Additionally, we explore the irregularity of HAI and AMR rates within the AP-HP. This inconsistency cannot solely be attributed to variations in antibiotic consumption. Through the development of new indicators for resistance and infections, we have identified structural and organisational factors that are linked to a higher frequency of these phenomena.Individual patient factors, such as the severity of illness (case-mix), are likely to be associated with an increased risk of resistance. We will investigate this further in our future research using the AP-HP Clinical Data Warehouse.The systematisation of this surveillance over time will make it possible to identify priority areas and steer prevention policies and targeted actions

Due to the high resistance rate and excessive use of antibiotics, French government has recommended that hospitals should monitor antibiotics consumption and incidence of methicillin-resistant Staphylococcus aureus (MRSA). Our aim was to determine factors that correlate with antibiotics use and Staphylococcus aureus resistance among 99 hospitals in south western France and to study relationship between these two indicators and policies developed by hospitals. Hospital type and hospitals areas stratification seems to be not enough homogenous to make valid comparisons. Number of beds could be used to explain difference when indicator of case mix is not available. Antibiotics policies and infection control program were associated with high consumption and high resistance rates. Fluoroquinolone use correlated with MRSA incidence but the relationships between antibiotic use and MRSA are complex and aggregated data do not prove causality link. However, such aggregated data may be helpful for comparison purpose

During the past sixty years, consumption of antibiotics has had an ecological impact on bacteria and has resulted in the emergence and dissemination of antimicrobial resistance. Control and prevention of this growing problem requires the collection and analysis of both antimicrobial use and resistance data. This thesis presents a new eco-epidemiological approach to better understand this problem using statistical methods such as time series analysis and multilevel analysis. The studies that were performed confirm the existence of a temporal relationship between antibiotic exposure and emergence of bacterial resistance, as weIl as an ecological effect of antibiotic use in a defined population. A substantial part of the thesis was devoted to data management and computer programming for the exploration of antibiotic use and bacterial resistance data. After validation, these computer tools could be applied to surveillance and be used in routine

The detection, monitoring and dissemination of bacterial resistance to antibiotics are a major issue worldwide since the discovery and spread of multi-resistant bacteria, in particular resistance to carbapenems, specifically among Enterobacteriaceae and bacteria of the genus Pseudomonas and Acinetobacter.The emergence and dissemination of carbapenem-resistant Gram-negative pathogens is a significant contributor to patient morbidity and mortality. Despite radical efforts in infection control and improvements in molecular diagnostics, carbapenem-resistant Gram-negative bacilli remain a formidable threat as few antimicrobial agents are reliably active and very little is expected to be available in the near future.The origin and source of resistance genes in the world are not well known and recent works suggest that domestic and wild animals, the environment (soil, water, rivers ..) but also the digestive tract of mammals and humans could represent a reservoir and an important source of resistance genes that may be transmissible to humans.It is in this context that this thesis project articulates with the following objectives: (i) The achievement of molecular epidemiological studies on carbapenem-resistant clinical and animal isolates collected from countries in the Mediterranean basin (Lebanon, Libya, France) and the characterization of the genetic determinants of this resistance; (ii) the description of new resistance mechanisms to imipenem; and finally (iii) The genome sequencing of clinical isolates resistant to carbapenems, the analysis of these genomes and the identification of mechanisms and genetic supports of the resistance to carbapenems and other antibiotics
