Positive Thyroid Peroxidase Antibody among Women with Polycystic Ovarian Syndrome Visiting an Infertility Clinic at a Tertiary Care Centre.

Abstract

Polycystic ovarian syndrome is the most common endocrine-metabolic disorder, affecting women of reproductive age groups, which shares various symptoms with thyroid dysfunctions. Despite it predisposition of aforesaid cohorts to autoimmunity, these etiologies have not adequately been studied in them. This study aimed to find out the prevalence of positive thyroid peroxidase antibodies among women with polycystic ovarian syndrome visiting an infertility clinic at a tertiary care centre. This was a cross-sectional study conducted at a tertiary care centre among patients visiting the infertility clinic at the Department of Obstetrics and Gynaecology from 21 September 2022 to 21 February 2023. Biochemical analysis of thyroid hormones, gonadal hormones, anti-mullerian hormone and thyroid peroxidase antibody were done in Abbott ARCHITECT ci4100 and SNIBE Maglumi 800 autoanalyzer. A convenience sampling method was used. The point estimate was calculated at a 95% Confidence Interval. Among 70 participants, thyroid peroxidase antibody was positive in 16 (22.86%) (13.02-32.69, 95% Confidence Interval). The mean age of the patients was 28.25±5.26 years. In the individuals with thyroid-stimulating hormone below 2.5 mIU/l, 5 (31.25%) had positive thyroid peroxidase antibody titre. The prevalence of positive thyroid peroxidase antibodies among women with polycystic ovarian syndrome is similar to other studies done in similar settings. Regular monitoring of thyroid peroxidase antibodies is recommended in these women to guide conception in order to evade inevitable adverse pregnancy outcomes. anti-thyroid autoantibodies; autoimmunity; infertility; prevalence; polycystic ovary syndrome.
