ABSTRACT
Coeliac disease [CD] may be associated with several liver disorders including primary biliary cirrhosis, primary sclerosing cholangitis and autoimmune hepatitis. Furthermore preliminary data suggest a causative role of CD in steatosis and steatohepatitis. The aim of present study was to determine the prevalence of CD in a series of patients with non-alcoholic fatty liver disease [NAFLD]. In a cross sectional study [2008-2010], 403 consecutive NAFLD patients [127 female and 276 male] referred to GI clinics of the Zahedan University of Medical Sciences were included. IgA anti-tissue transglutaminase [Anti-tTG] was used for screening of coeliac disease. In the patients with a positive serologic test, duodenal biopsies were taken to confirm the diagnosis. The mean +/- SD of the age and BMI of patients were 37.4 +/- 12.4 years and 28.3 +/- 4.15 kg/m[2] respectively. BMIs lower than 25 kg/m2 were found in 58 subjects [14.5%]. Furthermore diabetes mellitus and hyperlipidaemia were diagnosed in 48 [11.9%] and 84 [20.8%] individuals respectively. Positive Anti-tTGs were found in 14/403 [3.4%] and 13/403 [3.2%, 95% CI 1.5-4.9] had coeliac disease according to the modified Marsh classification; 8 had type I, 3 type II, 1 type IIIA and 1 type IIIB lesions. According to our data, prevalence of CD in the subjects with NAFLD is higher than the rates reported in the general population. Therefore screening for CD in selected cases of NAFLD may be appropriate
