Autoantibodies fail to influence reproductive parameters in patients with Hashimoto thyroiditis, reports research
A new study published in the journal of Endocrine Research found that autoantibodies had no effect on reproductive characteristics, despite a mild correlation observed among thyroid volume, preterm deliveries and the quantity of antithyroid peroxidase (TPOAb).
Among autoimmune diseases, Hashimoto's thyroiditis (HT) is the most common where the thyroid stimulating hormone (TSH) levels are up, serum free thyroxine (FT4) levels are low, anti-thyroid autoantibodies like TPOAb and anti-thyroglobulin (TGAb) are present, and there is local parenchymal lymphocytic infiltrate. According to studies, eutrophic women with thyroid autoimmunity (TAI) have a greater risk of pregnancy morbidity and loss. Also, inflammatory processes of viral/bacterial origin and autoimmune have been identified as influencing cellular structures at the maternal-fetal interface and determining various abnormalities in the product of conception. Research of the role of TAI in infertility and assisted reproduction results in women without dysfunction found that TAI had no effect on the number of oocytes retrieved, the chance of fertilization, implantation or clinical pregnancy.
In order to assess the presence as well as concentration of antithyroglobulin (TGAb) antibodies and antithyroid peroxidase at the onset of Hashimoto's thyroiditis (HT) as well as their correlation with disease attributes and reproductive parameters both before and after diagnosis, Rafaela and colleagues conducted this study.
A total of 65 women with HT were included in this cross-sectional research, which was conducted in an outpatient clinic. Medical records were reviewed and interviews were conducted to gather data. The factors included illness features, TPOAb and TGAb levels, live births, preterm births, infertility and pregnancy losses. This research employed Spearman correlation, Mann-Whitney test, and chi-square or Fisher's exact tests.
