Study on correlation of thyroid hormone level, lipid and glucose metabolism and blood uric acid in patients with hyperthyroidism / 国际检验医学杂志

ABSTRACT

Objective To explore the correlation of thyroid hormone level, blood glucose level, blood lipid level and blood uric acid in patients with hyperthyroidism.Methods Totally 87patients with hyperthyroidism who were treated in our hospital from June 2015to December 2017were selected as the observation group, the other 69healthy people in the same period were selected as the control group.The fasting blood glucose (FBG), total cholesterol (TC), three glycerol (TG), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), free three triiodothyronine (FT3), free thyroxine (FT4), thyroid stimulating hormone (TSH) and blood uric acid level were compared, and the correlation among the above indicators were analyzed.Results The levels of FBG, FT3, FT4and blood uric acid before treatment in the observation group were higher than those of the control group, and the levels of TSH, TC, TG, HDL-C and LDL-C were lower than those of the control group, the differences were statistically significant (P＜0.05).After treatment, the levels of FBG, FT3, FT4and blood uric acid were significantly decreased in the observation group, while the levels of TSH, TC, TG, HDL-C and LDL-C increased significantly, the differences were statistically significant between before and after treatment (P＜0.05).The levels of FT3and FT4were positively correlated with blood uric acid and FBG level in hyperthyroidism patients, and negatively correlated with the levels of TC, TG, HDL-C and LDL-C.The level of TSH was positively correlated with the levels of TC, TG, HDL-C and LDL-C, and had a negative correlation with the levels of FBG and blood uric acid.Conclusion The thyroid hormone level is closely related to lipid and glucose metabolism and blood uric acid level in hyperthyroidism patients.When the thyroid hormone is corrected, the blood glucose and blood lipid indexes turn to normal.It suggests that the clinical treatment of hyperthyroidism should be taken as the main means to correct the abnormal thyroid hormone.
