Introduction: Celiac disease is an autoimmune disorder that involves gluten intolerance and can be triggered by environmental factors including hepatitis B virus (HBV) infection. This study aimed to describe the prevalence of celiac disease in individuals with HBV infection and to describe the clinical and laboratory characteristics of celiac disease associated with HBV. Methods: This cross-sectional study included 50 hepatitis B patients tested for IgA anti-endomysial antibodies (EMAs) and tissue antitransglutaminase (TTG) between August 2011 and September 2012. Results: Fifty patients were included with a mean age of 46.0 ± 12.6 (46.0) years; 46% were female and 13% were HBeAg+. Six patients had positive serology for celiac disease, four were EMA+, and fi ve were TTG+. When individuals with positive serology for celiac disease were compared to those with negative serology, they demonstrated a higher prevalence of abdominal pain (100% vs. 33.3%, p = 0.008), lower median creatinine (0.7mg/dL vs. 0.9mg/dL, p = 0.007) and lower mean albumin (3.6 ± 0.4g/L vs. 3.9 ± 0.3g/L, p = 0.022). All individuals with positive serology for celiac disease underwent upper digestive endoscopy, and three of the patients exhibited a macroscopic pattern suggestive of celiac disease. Histologically, fi ve patients demonstrated an intra-epithelial lymphocytic infi ltrate level > 30%, and four patients showed villous atrophy associated with crypt hyperplasia on duodenal biopsy. Conclusions: An increased prevalence of celiac disease was observed among hepatitis B patients. These patients were symptomatic and had signifi cant laboratory abnormalities. These results indicate that active screening for celiac disease among HBV-infected adults is warranted.
