Methods: A 6 months follow up was performed on 135 healthy women with assessment of TSH, T3, T4 and antithyroid antibodies (anti thyroglobulin and anti peroxidase). Correlation of diverse obstetrical parameters with the appearance of antithyroid antibodies at 2 and 6 months postpartum was determined. Results: Only two parameters were significant during the complete follow up: the newborn weight, which correlated with both antibodies (anti-thyroglobulin and anti-peroxidase) positivity and the maternal height, which exclusively correlated with anti-thyroglobulin positivity. Conclusions: Correlation of maternal height and newborn weight with positive autoantibodies allows to consider a future clinical screening test for this disorder.展开更多

There was no significant difference between relapse patients and patients without relapse for peak systolic velocity of pretreatment. The peak systolic velocities were significant difference between remissive and relapse patients. The MV1-MV2/MV1s was significant difference between remissive and relapse patients. Area under ROC curve of peak systolic velocities of the superior thyroid arteries of relapse patients and euthyroid subjects was 0.773, the cutoff point was 40.3 cm/s, and sensitivity and specificity were 84.6% and 65.0%, respectively. Area under ROC curve of MV1-MV2/MV1s of the superior thyroid arteries of remissive patients and relapse patients was 0.870, the cutoff point was 0.525, and sensitivity and specificity were 86.4% and 69.2%, respectively.Conclusion: The determination of peak systolic velocity of superior thyroid artery and relevant parameters can help predict relapse after anti-thyroid drug therapy of hyperthyroidism.展开更多

An universal salt iodization （USl） program has been implemented by the Chinese government since 1996. As a result, the goiter rate in 8- to 10-year old children decreased from 20.4% in 1995 to 5.8% in 2002.1 But the adverse effects of iodine excess such as iodine-induced hyperthyroidism, iodine-induced goiters, iodine-induced hypothyroidism, etc. have become a great concern to healthcare professionals as well as the general population. The impact of USI on antithyroid drugs （ATDs） might become a potential challenge to address. With a special grant from the Department of Disease Control, the Health Ministry of China, we conducted a prospective study on the effects of USI on ATDs at the thyroid section of the Endocrinology Clinic of Peking Union Medical College Hospital （PUMCH）, Beijing.展开更多

In 700 first-egree relatives, inquiry of medical history, physical examination (including eyes, thyroid, heart rate, etc), thyroid function tests (serum T3, T4 and TSH levels), determinations of thyroglobulin antibodies (TgAb) and thyroid microsomal antibodies (TmAb) were performed. For male (female) probands, the incidence of Graves' disease in male (female) first-degree relatives were investigated and their serum TgAb and TmAb were analysed. The incidence of these two kinds of autoantibodies in the male (female) first-egree relatives of familial and nonfamilial Graves' disease were analysed. Eighteen persons with positive TgAb and TmAb from 5 pedigrees had been followed up one year after initial determinations. Our results suggest that the positive rates of TgAb and TmAb in the first-egree relatives of Graves' disease were coincident with the incidence of Graves' disease, and the positive results of TgAb and TmAb in the first-egree relatives of Graves' disease may be an indicator of pre-raves' disease or pre-utoimmune thyroid diseases.展开更多
