Ovarian Reserve and Serum Concentration of Thyroid Peroxidase Antibodies in Euthyroid Women With Different Polycystic Ovary Syndrome Phenotypes

Abstract Background The human ovary is the target of autoimmune attack in cases of autoimmune disorders, which can cause ovarian dysfunction. Due to the higher prevalence of Hashimoto’s Thyroiditis (HT) in Polycystic Ovary Syndrome (PCOS) patients, we aimed to evaluate ovarian reserve and the effect of autoimmune exposure time on ovarian reserve in PCOS patients with HT by Anti-Müllerian hormone (AMH) levels. Methods Forty-six PCOS patients and 46 PCOS with HT diagnosed patients who are between 18 and 35 years old were recruited for this study. Detailed medical histories were obtained from all participants. Polycystic ovary image was evaluated and antral follicles were counted by transvaginal ultrasound. Modified Ferriman Gallwey score, body mass index, waist/hip ratio of the patients were examined. Hormonal, biochemical profiles and AMH levels of the patients were evaluated during the early follicular phase. The data of both groups were statistically analyzed with SPSS 18.0. Results 20 (43.5%) patients in the PCOS group were fertile, 8 (17.4%) patients in the PCOS + HT group were fertile, fertility rate was significantly lower in PCOS + HT group. The mean AMH value was 8.8 ± 8.8 in the PCOS + HT group and 12.4 ± 8.1 in the PCOS group and it was significantly lower in the PCOS + HT group (p = 0.043). AMH values were significantly negatively correlated with anti-thyroid peroxidase antibody (anti-TPO) level and the duration of HT. There was a significant positive correlation between the anti-TPO level and the duration of HT. Conclusıon We pointed out that the coexistence of PCOS and HT, two prevalent diseases of reproductive age, further diminished ovarian reserve. More exposure of the ovaries to autoantibodies can cause ovarian destruction, similar to the thyroid gland like HT. Because of all these close relations with PCOS and thyroid dysfunctions, we recommend evaluating both thyroid autoantibodies and hormone levels in PCOS patients at the first visit. Patients with PCOS + HT should be monitored more closely to determine the fertility treatment options and control premature ovarian failure (POF) table.

Objectives: Polycystic ovary syndrome (PCOS) is a rampant endocrine disorder distressing women of child bearing age worldwide. Many current researches have detected the presence of some organ specific and non-specific autoantibodies in females with PCOS. Study Design: Cross Sectional study. Setting: Aziz Fatimah Hospital, Faisalabad, Pakistan. Period: April to September 2017. Material & Methods: This study comprised of 88 female subjects of 17-35 years old. Participants were divided into four group’s i.e PCOS obese females, PCOS non-obese, obese females without PCOS and age matched controls. Thyroid function was evaluated by the measurement of serum TSH, FT3 and FT4 levels. Thyroid peroxidase antibody was detected as an indicator of thyroid autoimmunity. All parameters were measured by chemiluminescence immunoassay technique (CLIA). SPSS version 22 was used for the statistical analysis of the data. Results: Out of total 88 female participants, 38.6% were hypothyroid and 61.4% were euthyroid females. While on comparing the percentages of hypothyroidism among the study groups PCOS, non-PCOS patients and obese we found higher percentages of hypothyroidism among non-obese PCOS. Thyroid peroxidase antibody levels were higher in PCOS obese subjects. PCOS patients have 15 times more risk for hypothyroidism as compared to non-PCOS patients. Conclusion: Hypothyroidism was commonly found in PCOS patients with high levels of TPO-Antibody indicating that PCOS is an independent risk factor for hypothyroidism which suggests that evaluation of thyroid function and autoimmunity must be deliberated in PCOS patients.
