Relation Between Tiroid Status with Glycemic Control of Type 2 DM Patients at RSPAD Gatot Soebroto

Abstract

Background: Diabetes Mellitus (DM) is a group of symptoms that arise due to increased blood sugar levels. Diabetes Mellitus type 2 has a higher risk of developing thyroid dysfunction. Thyroid dysfunction can affect various body metabolism and result in insulin resistance, significantly affecting glycemic control in DM patients. This study aimed to determine the relation between thyroid status as assessed by the level of thyroid-stimulating hormone (TSH), free thyroxine (FT4), and glycemic control (HbA1c). Subjects and Method: A cross-sectional study. A sample of 38 DM patients was selected by purposive sampling. The dependent variable was glycemic control. The independent variables were TSH and FT4. Patients were classified into 4 quartiles (Q) based on their TSH and FT4 levels. Statistic test used was non parametric for category group of variables, which was Chi square test. Results: Mean of fasting blood glucose was 200,56 mg/dL (modus 137 mg/dL), mean of 2 hours post prandial blood glucose was 247 mg/dL (modus 305 mg/dL). Subjetcs with poor glycemic control dominated as much as 76%. Most subjects had TSH level at Q4 (36%), while most of the subjects had FT4 level at Q1 (34%). The results showed that 38 samples with poor glycemic control were 72% in the 4th quartile (Q4) (> 3.1750 mU / L) TSH, and 64.7% were in Q1 (≤ 11.8400) FT4. The analysis showed that there was a significant relation between TSH (p = 0.047) and FT4 (p = 0.041) with glycemic control in type 2 DM patients. Conclusion: FT4 and TSH levels relate to glycemic control in type 2 DM patients Keywords: TSH, FT4, HbA1c, Diabetes Mellitus Correspondence: Mila Citrawati.
