Texto completoBackground: In the last few years, several epidemiological studies have suggested that the timing of the introduction of gluten, as well as the pattern of breastfeeding, may play an important role in the subsequent development of celiac disease (CD). However, these case-control studies lack consistency, possibly due to limitations of a retrospective design. Aim: To evaluate the role of (a) age at gluten introduction on the incidence of CD in a large cohort of at-risk infants (first-degree relatives of patients with CD); (b) of other early environmental factors, particularly milk feeding, on the development of CD; (c) different HLA- DQ2/DQ8 molecules and genotypes (high risk versus low risk) on CD predisposition, and their interplay with infant nutrition patterns. Study design: Prospective multicentric randomized placebo-controlled clinical trial conducted in Italy. Patients and methods: Between October 2003 and June 2007 a total of 624 infants (49.8% M) at increased risk for celiac as defined by having a first-degree relative with CD were enrolled. Per protocol (a) infants were blindly assigned to introduce gluten in their diet either between the 4th and 6th month (group A) or after the 12th month (group B) and entered a follow-up period of 5 years, (b) diet (duration of breastfeeding and types of formulas, adherence to the dietetic plan, amount of gluten administered) and clinical data were collected during telephone or face-to-face interviews at 4, 7, 9, 12 months of age, (c) CD serology was tested at 15 (plus HLA), 24, 36 and 60 months of age. Results are relative to a representative sample varying from the 40% to the 90% of the whole cohort according to the different variables studied. Results: 55% were enrolled in group A and 45% in group B. Familiarity for CD was: 51% one sibling, 37% mother, 7% father, 4.8% mother plus a sibling and father plus a sibling respectively and 0.2% two siblings. HLA determination showed the presence of alleles: DQ2 in 85%, DQ8 in 6%, DQ2/8 in 2% and none in 7%. There was no difference in the studied variables according to weaning group. At 15 months 9/312 infants of Group A developed CD as compared with 1/247 of Group B (2.9% vs 0.4%; p<0.02); at 24 months 21/230 infants of Group A developed CD as compared with 10/188 of Group B (9.1% vs 5.3%; p=NS); a 36 mesi 6/151 developed CD as compared with 10/138 of Group B (3.9% vs 7.2%; p=NS). At 2 years the percentage of infants developing CD of Group A was significantly higher than Group B (13% vs 5.8; p<0.02). The risk of CD was significantly reduced in infants who were breast feeding at the time of gluten introduction compared with infants who were not breast feeding during this period (hazard ratio 3.0, 95% CI 0.40 to 5.6). Conclusions: The risk of developing biopsy-proven CD was significantly higher among infants weaned with gluten at 6 than at 12 months of age. A prolonged follow-up is required to clarify whether age at gluten introduction influences the risk of CD development or merely delays gluten sensitization.

Texto completoBackground: “Gluten-Related disorders (GRD)” is a collective term of the disorders take place due to the consumption of ‘gluten’ found in wheat and closely related cereals with a global prevalence around 5%. Celiac disease (CD), a form of GRD, is a T-cell mediated small intestinal, autoimmune disease triggered due to the ingestion of ‘gluten’ in genetically predisposed individuals. At least 1% global prevalence is affected with CD. Till date only accepted treatment available for CD is a lifelong adherence to a strict gluten-free diet (GFD). There are some effective biomarkers available for the diagnosis of CD but so far there is no reliable biomarker reported to assess the adherence to GFD. Aim: To find a suitable non-invasive biomarker for diagnosis and for the assessment of the adherence to GFD for CD and other GRDS. Methodology: Efficacy of multiple blood-dependent, non-invasive biomarkers for the diagnosis (Rapid HLA DQ typing method, EMA Biopsy) as well as for the adherence to GFD [Alkylresorcinol (AR), Gluten Immunogenic Peptides (GIP urine test), Intestinal Fatty Acid Binding Protein (i-FABP)] and blood-independent biomarkers i.e. quantitative analysis of gluten in food products through different antibodies (e.g. R5 and G-12 ab) was investigated in 9 different respective studies. Results: Out of 9 studies three studies are still in ongoing phase. Preliminary results showed that GIP quantitative and i-FABP test could be a reliable biomarker to assess adherence to GFD. Completed studies have shown that there is mild gluten contamination (9%) in naturally as well as labeled gluten-free food marketed in Italy. However, the Italian market is safe from the contamination of gluten in oral hygiene and cosmetic products.Another completed study confirmed that Celiac Gene Screen rapid HLA-DQ typing method is an affordble method (genetic-mrker) for the detection of CD-associated alleles. Conclusions: Extensive investigation for multiple potential biomarkers concludes that a sole biomarker is not enough. However,combination of biomarkers may help to manage CD. There is need of such more studies in future.

Texto completoNumerous pathologies, while developing in the absence of an external threat such as infection, exposure to toxins or predisposition for the formation of tumors, tend to develop an inflammatory condition and specific damage to the tissue with consequent activation of the immune system. Such conditions show activation of the innate immune system and an excess of inflammatory mediators, but no evidence of an antigen-specific immune response. Alternatively, there are diseases characterized by an activation of the adaptive immune response with T and B lymphocytes responding to the autoantigen in the absence of any detectable microbial aggression or tumor invasion; these pathologies constitute the vast majority of diseases considered to be of autoimmune origin. Currently, about 80 autoimmune diseases have been identified that affect 5.7% of the population even if, according to the latest data in the literature, their incidence is increasing. Autoimmune disease is defined as a condition in which tissue damage is caused by the reactivity of T cells or reactive antibodies to their own antigens. In some cases, a disease is assumed to be of autoimmune origin only because B and T lymphocytes are present in the affected tissue. Animal models for the study of these diseases have been extremely useful in helping to understand both the mechanisms that drive the onset of the disease and those of pathogenesis. There are two important elements for understanding the high frequency of autoimmune diseases: first, self-reactivity. Indeed, the repertoire of immunocompetent lymphocytes providing protective immunity is selected on the basis of self-reactivity. Regulating self-reactivity helps shape the immune system so that it does not become associated with tissue damage, which requires constant vigilance. The immune system maintains a precarious balance between the two: too little response leads to a potential non-recognition of "danger", while an over-expressed response can potentially lead to self-reactivity. Second, there is a genetic predisposition to autoimmunity and aspects of this predisposition may be similar for many different autoimmune diseases. Autoimmune disease therefore not only requires self-reactivity, but can also be affected by the genetic vulnerability of the target organ. Some of the recent studies on the genetic basis of autoimmunity show that the genetic factors that regulate the vulnerability of specific organs are distinct from those that regulate self-reactivity. Therefore, individuals can share pathways that promote self-reactivity, but present with several autoimmune diseases. Celiac disease (CD), for example, is an immune-mediated systemic disease induced by the presence of gluten in genetically predisposed subjects, characterized by an autoimmune reaction against tissue transglutaminase (tTG), an enzyme that deaminates gliadin in subjects carrying the HLA- alleles. DQA1 and DQB1 and for the heterodimers DQ2 or DQ8. Celiac disease manifests itself with a condition of chronic malabsorption: typical intestinal damage is characterized by the destruction of the villi and hyperplasia of the crypts, but nowadays it is possible to keep it under control by eliminating gluten from the diet. At the molecular level, it has been shown that exposure to gliadin (a prolamine that together with glutenin makes up gluten) induces an inflammatory response that causes damage to the villi lining the small intestine (villous atrophy). The potential celiac patient is characterized by a high expression of IL-10 and a significant increase in the IL-10 / IFN-y ratio, followed by a higher density of regulatory cells such as CD4 + CD25 + Foxp3 + T reg, which exert suppressive effects. Although it is recognized that CD is mediated by a Th1 response, the mechanism by which Th1 cells are induced and maintained in the gut of patients is not yet clear. Evidence indicates that an active and dynamic interaction between immune and non-immune cells plays a crucial role in initiating and modeling this pathological pathway, and that cytokines are the main mediators of this cross dialogue. In particular, IL-21 seems to have a key role in this phenomenon: its expression, in fact, was greater in the intestinal mucosa of patients with active CD (both pediatric and adult) than that of CD patients treated with a diet. gluten-free and that of control subjects. IL-21 is a cytokine strongly involved in the mechanisms of inflammation and autoimmunity, with its involvement in the development and maintenance of specific classes of T lymphocytes (CD4 + and CD8 +) and B lymphocytes. The goal of this study was to investigate and analyze the possible role of this cytokine in the development of celiac disease. In particular, we have dealt with the quantitative evaluation of the relationship between the serum levels of IL-21 and the serum titers of the anti-tTG IgA autoantibodies with relative comparison of the tissue damage that occurs at the level of the duodenal mucosa in patients considered. active. In this study the sera of 160 CD patients, 120 untreated and 40 treated (on a gluten-free diet), and those of 45 healthy volunteers, with control function, were analyzed. The results demonstrated that CD patients at diagnosis expressed significantly higher IL-21 concentrations than dietary and control CD patients. Furthermore, the data obtained showed a positive correlation between the levels of IL-21 and the concentrations of IgA anti-tTG autoantibodies, indicating a possible role of this cytokine in the activation of B lymphocytes. Finally, a positive correlation was highlighted. IL-21 levels with damage to the duodenal mucosa: this allowed us to hypothesize the possibility of a strong immunomodulatory effect of IL-21 on the functions of cytotoxic T lymphocytes. This study provides further evidence of the emerging data on the potential role of IL-21 in the pathogenesis of CD, suggesting its involvement in the development and progression of CD.

Texto completoAccumulating data indicate that a dysregulation of the gut immune system may play a role in the development of Beta cell autoimmunity and type 1 diabetes (T1D). The aim of this study was to determine a possible link between the gut immune system and T1D, in particular, a possible role of gliadin as a T cell antigen in human T1D. Peripheral blood mononuclear cells (PBMC) were isolated from 25 children with T1D (aged from 3.4 to 19.6 yrs), 22 healthy controls (HC) (aged from 3.5 to 17 yrs), both negative for both anti-endomysial and anti-human tissue transglutaminase antibodies and 15 children with celiac disease (CD) (aged from 2.2 to 13.3 yrs). In the first part of the study, in 6 children with T1D, 5 with CD and in 6 HC, PBMC were cultured with or without OKT3 plus anti-CD28mAb. After 18 hours the expression of β7 integrin was determined by flow cytometry. In patients with T1D we observed a higher expression of Beta7 integrin on memory CD4+ T cells. After polyclonal stimulation we found a significant reduction of Beta7 expression on memory CD4+ T cell in T1D patients compared with healthy controls. In the second part of the study, in 19 children with T1D, 10 with CD and in 17 HC, PBMC were cultured with the peptic-tryptic digest of gliadin (PTG) and/or transgluatminase-treated (TG)-PTG at increasing concentrations, or left un-stimulated. PBMC proliferation was assessed on day 5 by [3H]-thymidine incorporation assay. We also assessed IFN-gamma and IL-4 production in culture supernatants by ELISA and we studied the expression of Beta7 integrin by flow cytometry. In T1D patients we detected a dose-response PBMC proliferation to both PTG and TG-PTG with the maximal proliferation at the concentration of 100 µg/ml. PBMC from 7 out of 11 T1D patients (64%) responded to 100 µg /ml PTG. Mean stimulation index (SI) in T1D patients was higher than in HC (2,95±2 vs.1,3±0,6 respectively, p=0,02). When PBMC were stimulated with TG-PTG we found that 6 out of 13 T1D (54%) and 2 out of 3 CD (67%) showed a proliferative response (T1D 2,4±2 vs. HC 1,5±0,7). In 3 of 7 T1D responders (43%) but not in HC, TG-PTG induced IFN-gamma production. In 1 patient with T1D we identified, after the stimulation with TG-PTG, a discrete population of CD4+ β7hi+ cells. Our data show that T cells expressing high levels of β7 integrin are detectable in peripheral blood of CD and T1D patients and we found an enhanced T cell-mediated gluten-specific immunity in T1D patients. This supports the hypothesis that immunity to oral proteins is altered in T1D patients. Long term follow-up is necessary to establish whether these subjects are at increased risk for developing celiac disease.

Resumo: Na atualidade a doença celíaca atinge aproximadamente 1% da população do mundo, e cerca de 3,1% dos pacientes com diabetes mellitus tipo I. A doença celíaca é caracterizada pela atrofia da mucosa intestinal na parte proximal e pela permanente intolerância ao glúten. Seu tratamento consiste em uma dieta isenta de glúten. Novas estratégias tem sido utilizadas para a fabricação de produtos de panificação isentos de glúten e sacarose, que se referem à utilização de pseudocereais, tais como amaranto e quinoa e edulcorantes, como por exemplo, sucralose e estévia. Diante disso, o objetivo desse estudo foi analisar a incorporação de farinha de amaranto e quinoa e edulcorantes (sucralose, estévia, acessulfame-k) no estudo do perfil sensorial e físico-químico em 6 amostras de pães isento de glúten e de sacarose. Os pães foram formulados contendo 20% farinha de amaranto e quinoa como substituto parcial da composição de amidos, sucralose, estévia e sucralose/acessulfame-K como edulcorantes substitutos da sacarose. Para compor o estudo de análise sensorial foram realizados Análise Descritiva Quantitativa (ADQ), teste de aceitação e análise tempo-intensidade para os estímulos gosto doce e amargo. O perfil físico-químico foi determinado por meio de volume específico do pão, cor, firmeza, atividade de água, composição centesimal, energia bruta e análise de imagem dos alvéolos. A análise estatística foi composta por Análise de Variância (ANOVA), teste de médias de Tukey ao nível de 5% de significância. Foi realizada uma correlação com os resultados da ADQ e impressão global do teste de aceitação por meio da análise de mínimos quadrados parciais (PLS). A ADQ foi realizada por 12 assessores, que geraram 24 termos descritores. Os pães com amaranto e quinoa foram percebidos com aroma e sabor característico desses pseudocereais, coloração marrom da casca do pão e maciez. No teste de consumidor verificou-se que a amostra com farinha de amaranto com sucralose foi a que obteve maior aceitação pelos consumidores. As análises-físico-químicas mostraram que os edulcorantes e as farinhas de amaranto e quinoa resultaram em bons substitutos para sacarose e amidos, respectivamente. A análise tempo-intensidade identificou um comportamento similar para a percepção do gosto doce entre as amostras. Quanto à percepção do gosto amargo, os pães de quinoa com edulcorantes sucralose e sucralose/acessulfame-K apresentaram maior intensidade máxima para esse estímulo. A correlação por PLS revelou que os atributos aroma e sabor de amaranto foram direcionadores de preferência positivos. Por meio desses resultados observa-se que a incorporação de farinha de quinoa e amaranto e edulcorantes em pães sem glúten e sacarose foi eficiente no desenvolvimento dos pães. Assim a pesquisa possibilitou o desenvolvimento de pães para uma população específica, ou seja, os celíacos, diabéticos ou ambos
Abstract: Nowadays the celiac disease reaches nearly 1% of the world population, and almost 3,1% of the patients that have mellitus type I diabetes are affected by this disease. It is characterized by the atrophy of intestinal mucosa in the proximal part and permanent gluten intolerance. The treatment is a gluten free diet. Recent studies have shown new strategies for the gluten free or/and sugar free baked products, with pseudocereals amaranth; quinoa and sweeteners as sucralose and stevia. The objective of this study was analyze the partial replacement of amaranth and quinoa flour incorporation and sucrose replacement with sweeteners (sucralose, stevia and acesulfame-K) in gluten and sucrose free bread in the sensorial and physicochemical profile in 6 samples. Different types of breads where produced with either 20% amaranth or quinoa flour replacing wheat flour and sucralose, stevia and a blend of sucralose/acesulfame-K as sucrose replacers. The sensory evaluations were performed by means of Quantitative Descriptive Analysis (QDA), acceptance test, time intensity analysis for the sweet and bitter stimuli. Physicochemical analyses were performed by specific volume, colour, firmness, water activity, proximate composition, gross energy and image analysis of the alveoli. Statistical data were statistically analised by Analysis of Variance (ANOVA) and Tukey¿s test average (in p<0.05 of significance level). Sensory profile by QDA and overall impression were correlated obtained in the partial least square analysis (PLS) correlations technique. The QDA comprised which 12 panelists and created 24 descriptive terms. The bread samples with amaranth and quinoa were identified with characteristic¿s pseudocereals aroma and taste, brown bread skin color and soft. In the acceptance test, samples with amaranth and sucralose were preferred (p<0,05). The physicochemical analyses showed the sweeteners and the amaranth and quinoa flour were good replacers for sucrose and starch respectively. Time-intensity analysis identified a substitute similar behavior concerning to the sweet taste perception among the samples, while the perception of bitterness in the quinoa with sweeteners sucralose and sucralose/acesulfame-K presented maximum intensity for that stimuli. The correlations by PLS analysis revealed that the aroma and taste amaranth attributes detected the positive preference. From these results it is possible to conclude that the incorporation of quinoa and amaranth flour and sweeteners in breads without gluten and sucrose was efficient in the development the bread for a specific population, in other words, celiac and diabetics

Texto completoObjective: to study the frequency of positive serology for celiac disease (CD) in patients with duodenal biopsies suggestive of this disease. Material and methods: cross sectional study. We included patients with duodenal biopsies histologically compatible with CD and antigliadin, antiendomysial and IgA antitransglutaminase antibodies. We defined a “case” of CD if there was a positive biopsy and either antiendomisial or antitransglutaminase positive antibodies. Results: thirty one patients were included in our study. Six were antiendomysial positive and 5 antitransglutaminase positive while the antigliadin was positive in 14 cases. Therefore, out of 31 patients only 10 had a serology compatible with CD and only one had positive both antibodies, antiendomysial and antitransglutaminase. Conclusions: a) we have found that most of the duodenal biopsies compatible with CD are not diagnosed with positive serology; and b) we found a low correlation between serological diagnostic tests.
