The prevalence of type 2 diabetes mellitus in patients with autoimmune thyroiditis in hypothyroid stadium

Introduction Autoimmune thyroiditis (AIT) and type 2 diabetes mellitus (DM2T) are the two most common endocrinological diseases worldwide. The relationship between T1DM and autoimmune thyreopathies is known and described, but the relationship between thyreopathies and diabetes type 2 is not clarified sufficiently through that studies manifest increasingly the connection between them. Objective Investigate the prevalence of DM2T in patients with AIT in hypothyroid stadium and compare with common population and investigate a possible association between thyroid and glucose metabolism parameters. Material and methods The group consisted of 100 patients (33 men and 67 women) with AIT without until now documented glucose metabolism disorder, average age 65.63 ± 19.05 years. The control group (CG) consisted of 100 subjects without until now documented thyreopathy and glucose metabolism disorder (37 men and 63 women), average age 63.85 ± 18.98 years. We realised venous blood sampling and determined thyroidal and glycid metabolism parameters. Results The study did not confirm higher prevalence of diabetes in patients with AIT [3 (3 %) vs 4 (4 %), p = 1]. There were no statistical significant differences between glycid metabolism parameters in patients with AIT and CG. Also no glycid metabolism parameters correlated to thyroidal parameters. Conclusion We did not confirm higher prevalence of DM in patients with AIT.Key words: autoimmune thyroiditis - diabetes mellitus type 2.
