Abstract
INTRODUCTION Celiac disease is a chronic autoimmune disorder that occurs following the ingestion of gluten, in genetically predisposed individuals. Patients with celiac disease, especially children, are likely prone to develop allergic reactions to different food allergens. However, the relationship between food allergy and celiac disease remains not elucidated. The aim of this pioneering study was to evaluate the prevalence of allergic food sensitization in children with celiac disease in Morocco. METHODS A total of 57 children with confirmed celiac disease, including 25 males and 32 females with a mean age of 8.6 ± 4.4 years, underwent a food allergen-specific immunoglobulin E (IgE) screening. This screening was conducted using a multiparametric immunodot assay (Euroline Food "Maghreb," Euroimmun). Statistical analysis was performed using R software. RESULTS Among the 57 cases tested, the overall rate of IgE-mediated sensitization to food allergens was found to be 48% (27/57), dominated by chicken, with 51.9% (14/27), followed by almond, 40.7% (11/27), sesame, 40.7% (11/27), potato 33.3% (9/27), and apple 18.5% (5/27). Of the s-IgE positive cases, 74% were sensitized at least to one allergen, 37% (10/27) were sensitized to both chicken and almond allergens. A significant correlation was observed between almond, sesame, chicken, and potato. CONCLUSION The current study highlighted a high prevalence of food allergen sensitization in children with celiac disease. This underlines the potential benefit in screening for food allergy in celiac patients.

Abstract
Introduction chronic hepatitis C (CHC) can cause severe complications, including fibrosis and cirrhosis. Very little is known about the prevalence of these complications in the Moroccan population. Methods the prevalence of liver fibrosis and cirrhosis using a non-invasive blood test (FibroTest and ActiTest) was studied in 699 Moroccan patients with CHC for 4 years (from January 2014 to December 2017). The serum immunological markers: α2-macroglobulin, haptoglobin, apolipoprotein A1 were analyzed nephelometrically on BN ProSpec® System. The serum biochemical markers: γ-glutamyltransferase, alanine aminotransferase, and bilirubin were performed using the VITROS® Chemistry System Ortho Clinical Diagnostic. A 699 patients with CHC were identified. Results the overall prevalence of cirrhosis (F4) was estimated at 31.8%. Thirteen point nine percent (13.9%) of patients with cirrhosis had a risk of developing esophageal varices and a 3.3% risk of developing primary liver cancer. The association between cirrhosis and age showed an increase in prevalence after age 55 years old [OR=7.68(95%CI=4.9-12.2); p<0.0001]. No significant association for cirrhosis was found for sex. Conclusion according to the results of FibroTest, 32% of patients with CHC had cirrhosis. The older age was independently associated with liver cirrhosis.

Abstract
OBJECTIVE We aimed to determine the prevalence of specific auto-antibodies to celiac disease (CD) in Moroccan type 1 diabetic (T1D) patients and compare the clinical and biological characteristics of seropositive and seronegative cases. PATIENTS AND METHODS A cross-sectional study was carried out on 276 T1D patients including 109 adults and 167 pediatric cases. The screening for CD was performed by an Elisa IgA anti-tissue transglutaminase antibody (tTGA) testing, combined with IgA quantification by nephelometry. Positive-IgA-tTGA cases were secondly tested for anti-endomysial antibodies (EMA) using an immunofluorescence technique, and the IgA deficiency cases were screened for IgG-tTGA. Patients with low positive tTGA titers underwent HLA-DQ2/DQ8 typing. Sociodemographic and clinical data of the patients were collected using a hetero-administered questionnaire. The comparison of clinical and biological data between seropositive and seronegative diabetics was done using independent T, Mann-Whitney U, chi-squared, and Fisher tests, which were considered significant if p value <0.05. RESULTS The prevalence of CD-specific auto-antibodies was estimated to be 9.1% (IC = 95%), with 25 positive cases in tTGA and EMA testing. Eight cases displayed low titers of IgA-tTGA, among which 4 were positive for HLA-DQ2, 1 for HLA-DQ8, and 1 for both DQ2 and DQ8. The other 2 cases had a biopsy-proven CD. Compared to seronegative patients, seropositive cases had a higher percentage of associated autoimmune disorders (16% vs. 2.4%, p=0.008), with a significant lower height Z-scores (median: -0.90 (-3.93 to 0.95) vs. -0.51 (-4.54 to 2.18), p=0.029) and a higher HbA1c level (median: 11.30% (7.31 to 16.00) vs. 9.30% (4.40 to17.31), p=0.022). CONCLUSION The current study gave evidence of a high prevalence of CD specific auto-antibodies in T1D population. The co-existence of these two conditions was associated with a poor glycemic control, a lower height, and other autoimmune diseases. These findings may suggest the necessity of a systematic screening of CD in T1D patients.
