Abstract
- Purpose: To investigate the serum levels of uric acid (UA) in obese acanthosis nigricans (AN) patients with different thyroid hormones (THs) levels within the normal range. Methods: We investigated 834 obese patients (385 females and 449 males) with euthyroid function in the department of endocrinology of shanghai 10th people's hospital from 2011 to 2019 with the median age of 29 years (interquartile range 22-36 years) for this study. 343 patients were diagnosed of AN. The cut-offs for thyroid-stimulating hormone (TSH), free triiodothyronine (FT3) and free thyroxine (FT4) were 2mIU/L, 16mIU/L and 5mIU/L, respectively. Results: In male obese patients, AN patients with high TSH and FT4 had higher levels of UA compared to those with high TSH and low FT4 (523.20±120.98 vs. 477.56±86.92umol/L, P=0.036) and showed a correlation with fasting C-peptide (FCP) (r=0.330, P=0.029). The TSH, FT3, and FT4 alone did not showed any predictive value in male patients. In female patients, high FT3 was associated with higher levels of UA (388.47±100.95 vs. 366.33±82.40umol/L, P=0.019). However, the predictive value of FT3 in female was obtained only in low TSH subgroup (low TSH+ high FT3 vs. low TSH+ low FT3, P=0.033) not in high TSH patients. The levels of fasting insulin, 2h-insulin, FCP, 2h C-peptide, total cholesterol, triglyceride and testosterone were in correlation with higher UA levels in female obese patients with low TSH and high FT3(all P<0.05). Conclusion: The metabolic characteristics of UA are found to differ in obese patients with euthyroid function, in which AN plays an important role for male obese patients with high TSH and high FT4. But in the case of female, a combination of THs instead of AN showed it's unique in UA metabolism. Disclosure: J. Zhang: None. G. Li: None. X. Cheng: None. X. Wang: None. M. Jayachandran: None. Y.
