AbstractThis study aims to evaluate the correlation between serum thyroid hormone levels and hepatitis B virus (HBV) DNA and HBV genotypes in pregnant women with chronic hepatitis B. A total of 96 pregnant women with chronic HBV-infected pregnant women between January 2020 and December 2022 were selected as the observational study subjects. About 50 HBV-uninfected pregnant women during the same period were selected as the control group. Serum thyroid hormone levels at different stages of pregnancy, including free triiodothyronine (FT3), free thyroxine (FT4), thyroid stimulating hormone (TSH), thyroperoxidase antibody (TPOAb), and thyroglobulin antibody (TGAb), were compared between the 2 groups. Thyroid hormones levels were also compared between HBV-DNA-positive and HBV-DNA-negative women in the HBV-infected pregnancy group, and to determine the correlation between thyroid hormones levels and HBV-DNA load and HBV genotype in HBV-DNA-positive pregnant women. The TSH levels in mid and late pregnancy and TPOAb levels in early, mid, and late pregnancy of HBV-infected pregnant women were higher than those in the same period in HBV-uninfected pregnant women (P < .05). The TPOAb and TGAb levels in early, mid, and late pregnancy of HBV-DNA-positive pregnant women were higher than those in the same period in HBV-DNA-negative pregnant women (P < .05). The HBV-DNA load and FT3 or FT4 levels were negatively correlated (P < .05), and the HBV-DNA load and TGAb levels were positively correlated (P < .05). However, there was no statistical difference in thyroid hormone levels between different HBV genotypes (P > .05). The thyroid hormone levels will change in pregnant women infected with hepatitis B virus, and there is a certain correlation between HBV-DNA load and thyroid hormone levels. Therefore, timely monitoring of thyroid hormones and HBV-DNA load can provide early prevention and treatment for HBV infection in pregnant women, ensuring the health of pregnant women and fetuses.Copyright © 2024 the Author(s).
