Abstract
OBJECTIVES: Autoimmune diseases are known to occur in people with Down's syndrome (DS), especially celiac disease, type 1 diabetes mellitus (DM), and hypothyroidism. Since there are common genetic risk factors involved in the occurrence of these autoimmune disorders, the risks would differ in different populations. We sought to determine the prevalence of type 1 DM, celiac disease, and hypothyroidism in Emirati patients with DS in Abu Dhabi, UAE. METHODS: Ninety-two patients with DS were investigated for the presence of anti-thyroid antibodies, antithyroglobulin, and anti-thyroid peroxidase antibodies for hypothyroidism, anti-glutamic acid decarboxylase antibodies for type 1 DM, and anti-tissue transglutaminase immunoglobulin A antibodies for celiac disease. RESULTS: Karyotyping was performed on 89 patients. Eighty-seven had non-disjunction of chromosome 21 (97.8%), one was a mosaic, and one had translocation. Of the patients studied, 19.6% had hypothyroidism, 4.3% had type 1 DM, and 1.1% had celiac disease. Out of the 92 patients studied, 66 (71.7%) did not have any autoimmune disease, 25 (27.2%) had one autoimmune disease, and one (1.1%) had two autoimmune diseases. CONCLUSIONS: Celiac disease was the least prevalent autoimmune disease in patients with DS patients, while type 1 DM and hypothyroidism were both significantly associated with DS.
