RESUMO
OBJECTIVE: To do a serological screening for celiac disease in patients with unexplained liver cytolysis. MATERIALS AND METHODS: Fifty-six patients with liver cytolysis without known aetiology were studied. Endomysial antibodies were determined by indirect immunofluorescence on human umbilical cord. Two thousand and five hundred blood donors served as control group. For statistical analysis, we used Chi-square or Fisher's exact test. RESULTS: The frequency of IgA endomysial antibodies in our patients was significantly higher than in the control group (8.92% vs. 0.28%, p < .001). In female, endomysial antibodies were significantly more frequent in patients than in healthy subjects (12.12% vs. 0.4%; p < .001). In male, endomysial antibodies were significantly more frequent in patients than in healthy subjects (4.34% vs. 0.22%; p = .006). The frequency of positive EMA in female patients was higher than in male, but the difference was not statistically significant (12.12% vs. 4.43%; p = .6). Two patients were non-compliant with the gluten-free diet. One patient was out of touch. For the two other patients, transaminase levels reverted to normal level within six months of strict gluten withdrawal. CONCLUSIONS: A screening for celiac disease should be included within the diagnosis protocol of liver cytolysis.
