Expressions of glycemic parameters, lipid profile, and thyroid hormone in patients with type 2 diabetes mellitus and their correlation.

Objective: This study aimed to investigate the expressions of glycemic parameters, lipid profile, and thyroid hormone in type 2 diabetes mellitus (T2DM) patients and their correlation. Methods: Eighty‐four patients with T2DM in our hospital were included as the observation group. The T2DM patients were divided into mild group, moderate group, and severe group according to the fasting plasma glucose (FPG) level. Another 84 healthy subjects in the same period of health examination in our hospital were included as the control group. The levels of glycemic parameters, (HbA1c and FPG), lipid profile (TC, TG, LDL‐C, and HDL‐C) and thyroid hormone (FT3, TSH, and FT4) were measured by automatic biochemical analyzer. The correlation between glycemic parameters, lipid profile, and thyroid hormone was analyzed by Pearson correlation analysis. Results: The FPG, TC, TG, LDL‐C, HbA1c, and TSH levels were significantly elevated, while the HDL‐C and FT3 levels were significantly declined in the observation group versus to control group (p <.05). The levels of HbA1c, FPG, TC, LDL‐C, and TSH were significantly increased, while the levels of HDL‐C and FT3 were decreased in moderate and severe groups, when compared to mild group (p <.05). The levels of HbA1c, FPG, TC, LDL‐C and TSH were higher, while the level of FT3 was lower in severe group than those in moderate group (p <.05). Pearson Correlation analysis showed that FT3 level in T2DM patients was positively correlated with FPG, HbAlc, TC, TG, and LDL‐C levels (p <.05), but negatively correlated with HDL‐C level (p <.05). TSH level was negatively correlated with FPG, HbAlc, TC, TG, and LDL‐C levels (p <.05), while positively correlated with HDL‐C level. Conclusion: The thyroid hormone levels were of clinical significance in evaluating glycolipid metabolism and severity of T2DM. Clinical detection of glycolipid metabolism and thyroid hormone levels in T2DM patients is of great significance for diagnosis, evaluation, and targeted treatment of the disease.
