Type 2 Diabetes and Hashimoto Thyroiditis-Possible Associations and Clinical Correlations - Preliminary Results

Abstract Background and aims: The primary objective is to evaluate the possible relationship between Type 2 Diabetes (T2DM) and Hashimoto Thyroiditis (HT), since the only correlation described until now is between Type 1 Diabetes and HT based on the autoimmune mechanism. The secondary end-point is to evaluate if there is a correlation between the characteristics of Type 2 Diabetes and autoimmune thyroiditis and if the metabolic component may be a factor of association. Material and method: We designed a retrospective, observational research, enrolling patients from “Sanamed” Hospital from Bucharest. Between 2016 and 2017 in our clinic a number of 150 patients were enrolled, in the following groups: 50 only with T2DM, 50 only with HT and 50 with both T2DM and HT. Results: The main observations of the study were the following: the prevalence of obesity was higher in patients with T2DM (p<0.001) than in the group with HT (p<0.001); Dyslipidemia was higher in the HT group (p<0.001) than in the group of T2DM (p<0.001); Ischemic cardiac disease was more frequent in the HT group (p<0.001) than in the Diabetes group (p<0.001); in the group that had both T2DM and HT, the HbA1c was correlated with pre-existing Thyroid pathology (p<0.001), also Dyslipidemia was associated with hepatic steatosis (p<0.001). Conclusions: After assessing all the parameters we have reached the conclusion that there is an association between the characteristics of T2DM and HT, as well as an interaction between these two diseases, considering their metabolic component.
