A Comparative Study on Insulin Secretion, Insulin Resistance and Thyroid Function in Patients with Polycystic Ovary Syndrome with and without Hashimoto's Thyroiditis.
2021
Objective The incidence of Hashimoto's thyroiditis (HT) in patients with polycystic ovary syndrome (PCOS) is significantly higher than in normal controls, and there is a risk of more severe metabolic symptoms when the two diseases occur together. This study compares insulin secretion, insulin resistance (IR) and thyroid function in patients with PCOS with and without HT. Methods A total of 164 patients (52 patients with HT (HT+) and 112 patients without HT diagnosed PCOS at our hospital were enrolled for testing of oral glucose tolerance, insulin release, thyroid function, the presence of thyroglobulin and thyroid peroxidase antibodies, and blood lipid levels. Results Patients with PCOS and HT had higher insulin secretion and IR levels than those without HT, while free thyroxine and thyrotropin levels were significantly lower. The ratio of free thyroxine to thyrotropin was higher in patients with HT. Conclusion HT may related with IR and relatively low thyroid function in patients with PCOS. Thus, thyroid function and autoimmune status in patients with PCOS should be evaluated in clinical practice.
