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

The two subtypes, Pituitary RTH (PRTH) and Generalized RTH (GRTH), cause clinically distinguishable patient presentations. In PRTH, typically only the pituitary gland is resistant to thyroid hormone (TH) while the rest of the body maintains sensitivity. Selective pituitary resistance to thyroid hormone results in dysregulation of thyroid hormone homeostasis with clinical presentation as either euthyroid or hyperthyroidism. PRTH is characterized by elevated thyroid hormone levels with an elevated or inappropriately normal TSH concentration. Herein we describe a case report of a 70-year-old woman who complained of weight loss of over 35 lbs., palpitations, jitters, hair loss, diarrhea, fatigue, muscle weakness, etc. over 6 months, thus, indicating the presence of iatrogenic hyperthyroidism while receiving levothyroxine 175 ug daily prescribed by her primary care provider because of a reported history of “Graves disease” treated by radioactive iodine ablation of the thyroid several years ago. The daily dose of levothyroxine had been increased gradually at an interval of 3 months over a year because of persistent elevation of serum TSH level. Laboratory tests revealed markedly elevated Free T4, Free T3 and TSH levels, along with low concentrations of all lipid fractions, serum creatinine and urea nitrogen levels, indicating TSH induced hyperthyroidism or PRTH. Further testing documented a mutation of thyroid hormone receptor beta gene 2 confirming presence of PRTH. We believe that the initial diagnosis of Graves Disease was erroneous and I-131 ablation further confounded and missed the diagnosis of PRTH. Thus, the purpose of this report is to report a patient with PRTH and describe potential pitfalls in diagnosis and management of this rare disorder.展开更多

METHODS: We investigated 112 consecutive Caucasian patients (48 females and 4 males with Graves' disease and 54 females and 6 males with Hashimoto' s thyroiditis HT), at their first diagnosis of ATDs. We tested for H. pylori in stool samples using an amplified enzyme immunoassay and Cag-A in serum samples using an enzyme-linked immunoassay method (ELISA). The results were analyzed using the two-sided Fisher' s exact test and the respective odds ratio (OR) was calculated. RESULTS: A marked correlation was found between the presence of H. pylori (P ≤ 0.0001, OR 6.3) and, in particular, Cag-A positive strains (P ≤ 0.005, OR 5.3)in Graves' disease, but not in Hashimoto's thyroiditis, where we found only a correlation with Cag-A strains (P ≤ 0.005, OR 8.73) but not when H. pylori was present. CONCLUSION: The marked correlation between H. pylori and Cag-A, found in ATDs, could be dependent on the different expression of adhesion molecules in the gastric mucosa.展开更多

Current guidelines for evaluation of cholestatic jaundice and reviews in Neonatology literature do not discuss hyperthyroidism in the differential diagnosis of cholestatic jaundice. We report two cases of neonatal thyrotoxicosis secondary to neonatal Graves’ disease that presented with cholestatic jaundice and elevated liver enzymes at birth. Early recognition of thyrotoxicosis as a cause of the hepatic disease in the neonate is crucial to prevent unnecessary diagnostic procedures and to initiate timely treatment.展开更多
