Methods:The clinical data of 68 pregnant women with Graves' disease and their newborns were retrospectively analyzed.Testing indicators included thyroid function tests and TRAb levels during pregnancy,at delivery,and within 2 weeks after birth.The serum TRAb and T_3,T_4,Free T_3,Free T_4,TSH levels were detected by radio receptor assay(RRA) and electrical chemiluminescence immunoassay(ECLIA),respectively. Results:The results showed that serum TRAb levels of the third trimester of pregnancy was positively correlated with that of the umbilical vein(n = 68,r= 0.8494,P<0.01),and that of the newborns(n = 68, r=0.8286,P<0.01).The incidence of neonatal hyperthyroidism was 11.8%(8/68).The serum TRAb levels in the 8 neonates with hyperthyroidism within 2 weeks after birth were 3 times higher than those in the normal neonates.Of these 8 neonates,2 had 15 times higher serum TRAb levels than those of normal neonates within 2 weeks after birth.The thyroid function and TRAb levels of these 2 neonates were still abnormal 6 months later. Conclusions:The risk of hyperthyroidism in newborn whose mother's TRAb levels were high in the third trimester of pregnancy was increased.This study suggests a significant correlation between TRAb levels in pregnant women with Graves' disease and the severity of neonatal hyperthyroidism.展开更多

Objectives: To study importance of TRAb in the diagnosis of Graves’ disease, distinguishing it from thyroiditis, and comparing it with clinical features and other tests such as TPOAb, US thyroid and thyroid scintiscan. Methods: A cross-sectional study was conducted on 120 patients attending endocrine clinicErbil city. Patients were studied on clinical feature basis and investigated with serum TRAb, TPOAb, TSH, Free T4, and Ultrasound examination of thyroid gland. Fisher exact test and Chi Square test of independence, Correlation coefficient and t-test of independence were used. Results: Fifty-two patients were found to have Graves’ disease;There was significant correlation between TRAb positivity and diagnosis of Graves’ disease p 0.05. Conclusion: A positive correlation was found between TRAb titer and positivity and no significant relation between TPOAb levels between Graves’ disease patients compared with thyroiditis patients, respectively.展开更多
