RESUMEN
Celiac is a hereditary disease presented with chronic inflammation of small intestine. Several studies supposed a relationship between Celiac disease and Inflammatory Bowel Disease [IBD]. Tissue trans-glutaminase antibody is one of the best serological markers in Celiac disease. This study was designed to evaluate the association of Celiac and IBD using tissue trans-glutaminase antibody. In this descriptive study 127 confirmed IBD patients who were referred by gastroentrologists 2005-08 enrolled into the study. A questionnaire was completed and tissue trans-glutaminase antibody was evaluated with ELISA method with a Cut-off=12 U/ml. Among 127 referred patients, serum samples of 102 patients were collected. Mean +/- SD of age was 36.17 +/- 15.2 years and 48% were males. Ulcerative colitis, Crohn's disease and other colitis were observed in 76 [74.5%], 7 [6.9%] and 19 [18.6%] of patients, respectively. Tissue trans-glutaminase antibody was positive [19.8 U/L] in one 46-years-old male patient with ulcerative colitis. Tissue trans-glutaminase antibody titer was not significantly different between IBD patients and controls, thus it seems not appropriate to suggest as one of the routine tests in IBD patients
