Abstract

Purpose: Several studies suggest a linkage between PCOS and autoimmunity with a high frequency of chronic autoimmune thyroiditis (AIT) reported in PCOS patients, however, this subject remains controversial. The aim of this study was to investigate the prevalence of AIT in PCOS women and identify parameters that would serve as independent predictors of AIT.

Methods: Two hundred fifty seven (257) PCOS patients according to the NIH criteria and one hundred forty three (143) controls, women with normal menstrual cycles and without clinical or biochemical hyperandrogenism, were recruited for the study. Anthropometric characteristics and a complete family history for AIT were recorded. Thyroid hormones, antithyroid antibodies, androgen, glucose and insulin levels were measured. Thyroid gland structure was evaluated by ultrasound scan.

Results: Patients and controls did not differ in age, BMI as well as genetic predisposition for AIT (p > 0.05). Women with PCOS presented higher levels of androgens and HOMA-IR index, as expected. AIT prevalence did not differ between women with PCOS and controls (4.8 vs 9.3%, p = 0.13). However, the subgroup of PCOS patients with AIT presented a significantly stronger predisposition for AIT (33.3 vs 4.7%, p = 0.004) compared to patients without AIT. In a multivariate regression model, a positive family history of AIT was proved to be the strongest independent predictor of AIT in the PCOS group (OR 7.06, 95% CI 1.04-47.79, R² = 0.39).

Conclusion: The prevalence of AIT in the PCOS patients does not differ from the general population when family predisposition to AIT is taken into account.

期刊介绍： Well-established as a major journal in today’s rapidly advancing experimental and clinical research areas, Endocrine publishes original articles devoted to basic (including molecular, cellular and physiological studies), translational and clinical research in all the different fields of endocrinology and metabolism. Articles will be accepted based on peer-reviews, priority, and editorial decision. Invited reviews, mini-reviews and viewpoints on relevant pathophysiological and clinical topics, as well as Editorials on articles appearing in the Journal, are published. Unsolicited Editorials will be evaluated by the editorial team. Outcomes of scientific meetings, as well as guidelines and position statements, may be submitted. The Journal also considers special feature articles in the field of endocrine genetics and epigenetics, as well as articles devoted to novel methods and techniques in endocrinology. Endocrine covers controversial, clinical endocrine issues. Meta-analyses on endocrine and metabolic topics are also accepted. Descriptions of single clinical cases and/or small patients studies are not published unless of exceptional interest. However, reports of novel imaging studies and endocrine side effects in single patients may be considered. Research letters and letters to the editor related or unrelated to recently published articles can be submitted. Endocrine covers leading topics in endocrinology such as neuroendocrinology, pituitary and hypothalamic peptides, thyroid physiological and clinical aspects, bone and mineral metabolism and osteoporosis, obesity, lipid and energy metabolism and food intake control, insulin, Type 1 and Type 2 diabetes, hormones of male and female reproduction, adrenal diseases pediatric and geriatric endocrinology, endocrine hypertension and endocrine oncology.
