Abstract:
Objective To explore the changes of serum thyroid peroxidase antibody (TPOAb), thyroglobulin (Tg), and anti-thyroglobulin antibody (Tg-Ab) in patients with gestational thyroid dysfunction and their relationship with pregnancy outcomes. Methods The clinical data were collected from 98 patients with gestational thyroid dysfunction in Nanchong Mental and Physical Hospital between January 2020 and December 2022. According to disease types, patients were divided into hyperthyroidism group (n=50) and hypothyroidism group (n=48). A total of 100 pregnant women with normal thyroid function during the same period were enrolled as the healthy group. The levels of serum thyroid stimulating hormone (TSH), free triiodothyronine (FT3), free thyroid hormone (FT4), TPOAb, Tg and Tg-Ab, and maternal and neonatal outcomes were compared among the three groups. According to maternal and neonatal outcomes, patients with gestational thyroid dysfunction were divided into normal pregnancy group (n=68) and adverse pregnancy group (n=30), and levels of serum TPOAb, Tg and Tg-Ab were compared between the two groups. Results Compared with the healthy group, level of serum TSH was decreased in the hyperthyroidism group (P<0.05), while levels of serum FT3, FT4, Tg, Tg-Ab and TPOAb were increased (P<0.05). Compared with the healthy group, levels of serum FT3 and FT4 were decreased in the hypothyroidism group (P<0.05), while levels of serum TSH, TPOAb, Tg and Tg-Ab were increased (P<0.05). The level of serum TSH in the hyperthyroidism group was lower than that in the hypothyroidism group (P<0.05), while levels of serum FT3, FT4, Tg, Tg-Ab and TPOAb were higher than those in the hypothyroidism group (P<0.05). There was no significant difference in the overall incidence of adverse pregnancy outcomes between the hyperthyroidism group and the hypothyroidism group (34.00% vs 27.08%, P>0.05), but the overall adverse pregnancy outcome rate in the two groups was higher than that in the healthy group (9.00%, P<0.05). The levels of serum TSH, TPOAb and Tg-Ab in adverse pregnancy group were higher than those in normal pregnancy group (P<0.05). Conclusion The levels of serum TPOAb, Tg and Tg-Ab are abnormally increased in patients with gestational thyroid dysfunction, which are all related to adverse pregnancy outcomes. Clinical attention should be paid to and early intervention should be taken.
