Abstract:
Objective:To investigate the correlation between thyroid hormone resistance and hyperuricemia in euthyroid population.Methods:It was a cross-sectional study. A total of 548 euthyroid subjects who were hospitalized or underwent physical examination in the Heart Center and Health Management Center of the First Affiliated Hospital of Tsinghua University from January 2021 to December 2022 were selected. Thyroid function, uric acid, blood lipid and other indicators were collected in the subjects, and thyroid function parameters were calculated: thyroid-stimulating hormone index (TSHI), thyrotropin T4 resistance index (TT4RI), parametric thyroid feedback quantile-based index (PTFQI), free triiodothyronine/free thyroxine (FT3/FT4), the sum activity of peripheral deiodinases (SPINA-GD) and the secretory capacity of the thyroid gland (SPINA-GT). According to uric acid level, the subjects were divided into high uric acid group and normal group, the clinical characteristics and thyroid function parameters of the two groups were compared, the correlation between thyroid hormone resistance and hyperuricemia was further explored.Results:Compared with the normal group, male proportion (94.4% and 52.5%), smoking rate (5.2% and 21.3%), body mass index [(27.10±3.96) and (24.26±3.42) kg/m 2], waist-to-hip ratio [0.90(0.86, 0.94) and 0.86(0.80, 0.91)], serum creatinine [(85.50±12.27) and (73.77±28.79) μmol/L], total cholesterol [(5.08±0.99) and (4.72±0.86) mmol/L], triglyceride [2.10(4.40, 5.59) and 1.14(0.79, 1.67)mmol/L], low-density lipoprotein [(3.19±0.97) and (2.85±0.84) mmol/L] and homocystine [(15.07±9.13) and (12.50±10.85) μmol/L] were all higher in the high uric acid group, and the level of high-density lipoprotein [1.15(1.43, 2.88) and 1.39(1.16, 1.64) mmol/L] was lower (all P<0.05). In the aspect of thyroid hormone and thyroid function parameters, the FT4[16.90(5.40,17.95) and 16.00(14.30,17.80) pmol/L], FT3[5.56(5.25, 5.94) and 5.22(4.81, 5.63) pmol/L], FT3/FT4 [0.34(0.31, 0.37) and 0.32(0.29, 0.36)], TSHI (2.70±0.50 and 2.58±0.60), PTFQI (0.406±0.332 and 0.335±0.353) and SPINA-GD [3.72(3.41, 4.05) and 3.52(3.18, 4.00) ]were all higher in high uric acid group than those in normal group(all P<0.05). Spearman correlation analysis showed that blood uric acid level was positively correlated with FT4 ( r=0.185), FT3 ( r=0.422), FT3/FT4 ( r=0.16), TSHI ( r=0.134), TT4RI ( r=0.09), PTFQI ( r=0.121) and SPINA-GD ( r=0.157) (all P<0.05). Conclusion:In people with euthyroid function, central resistance to thyroid hormone is correlated with hyperuricemia.
