As previously demonstrated, serum beta-human chorionic gonadotropin (β-hCG) is linked to identifying early gestational abnormalities. This research was aimed at investigating the correlation between serum β-hCG levels and thyroid metabolic function in pregnant women with hyperemesis gravidarum (HG). Ninety-one pregnant women with HG were selected as the study group and divided into early pregnancy (EP), mid-pregnancy (MP), and late pregnancy (LP) groups according to their gestational weeks, while 84 normal pregnant women were selected as the control group. Venous blood was collected from pregnant women in both groups and serum β-hCG levels were measured by chemiluminescent immunoassay. The levels of free thyroxine (FT4), free triiodothyronine (FT3), thyroid-stimulating hormone (TSH), thyroid peroxidase antibody (TPOAb), thyroid-stimulating hormone receptor antibody (TRAb), and thyroglobulin antibody (TgAb) were tested by chemiluminescent microparticle immunoassay. Visual analog scale (VAS) scores were utilized to assess the degree of HG. Pearson analysis was implemented to measure the correlations between serum β-hCG levels and serum FT3, FT4, TSH, TPOAb, TRAb, TgAb, as well as VAS scores and the correlations between β-hCG, FT3, FT4, TSH, TPOAb, TRAb, TgAb, as well as VAS scores and gestation period. The receiver operating characteristic (ROC) curve was plotted to analyze the diagnostic values of thyroid hormones, thyroid-related antibodies, and β-hCG levels for HG. Versus those in the control group, β-hCG, FT3, FT4, TPOAb, TRAb, TgAb levels, and VAS scores were higher and TSH levels were lower in the study group. Versus those in the EP group, β-hCG, FT3, FT4, TPOAb, TRAb, TgAb levels, and VAS scores of pregnant women in the MP and LP groups were decreased, and TSH levels were increased. Serum β-hCG levels of pregnant women with HG were positively correlated with FT3, FT4, TPOAb, TRAb, TgAb, and VAS scores and negatively correlated with TSH levels. Serum β-hCG, FT3, FT4, TPOAb, TRAb, TgAb levels, and VAS scores of pregnant women with HG had a negative correlation with the gestation period, while TSH levels had a positive correlation with the gestation period. The ROC curve analysis showed that β-hCG and thyroid function-related indicators were of high clinical values in the diagnosis of HG. Collectively, our article suggests that serum β-hCG expression of pregnant women with HG is abnormally elevated and closely related to the degree of HG and hyperthyroidism. In addition, β-hCG and thyroid function-related indicators have certain diagnostic efficacy for HG. [ABSTRACT FROM AUTHOR] |
