Prevalence of coeliac disease among adult patients with autoimmune hypothyroidism in Jordan

ABSTRACT

The prevalence of coeliac disease among patients with autoimmune hypothyroidism has not been studied before in Jordan and other Arab countries. A cross-sectional record-based review was made of all adult autoimmune hypothyroidism patients who attended a referral centre in Jordan, during an 8-month period. Coeliac disease in these patients was diagnosed by the attending physician based on positive serological tests for anti-endomysial antibodies IgA and IgG followed by duodenal biopsy to confirm the diagnosis of coeliac disease. Of 914 patients recruited, 117 [12.8%] were seropositive for coeliac disease. Of 87 seropositive patients who underwent duodenal biopsy, 39 had positive histological findings of coeliac disease [44.8%]. Extrapolating from these findings the overall rate of coeliac disease among autoimmune hypothyroidism patients was estimated to be 5.7%. In multivariate logistic regression coeliac disease was significantly associated with older age [> 40 years], presence of other autoimmune diseases, vitamin B12 deficiency and anaemia
