Diagnosis And Treatment For Sporadic Type of Painless Thyroiditis in Hyperthyroidism / 中国医师杂志

ABSTRACT

Objective To investigate the incidence of sporadic type of painless thyroiditis (SPT),to analyse its laboratory characteristics, and explore the influence of different treatments on prognosis. Methods 43 patients with SPT, who differentiated from 276 patients with typical thyrotoxicosis, were randomly divided into treatment group (n=22) and control group(n=21).Results the incidence of SPT was 15 58%,the laboratory examinations in SPT differed from those of Graves disease, Plummer's disease and Hoshimotos disease. In treatment group the thyrotoxicosis continued(37 23?4 28) days, the euthyroidism continued(16.43?3.42) days and hypothyroxinemia continued(18.65?6.31)days,only one patients(4.54%) showed that repeated episode and had not left lifelong hypothyroidism; In control group the thyrotoxicosis continued(68 35?8 32) days, the euthyroxinemia continued(31 45?7 23) days and the hypothyroxinemia continued(102 42?21 34) days, 3 patients(14 28%)showed that repeated episodes and two patients(9 52%) left lifelong hypothyroidism in following 1 5 years;Conclusions SPT has less incidence than Grave's disease and more incidence than plummer's disease or Hoshimoto's disease in thyrotoxicosis. The laboratory examination could differentiate each other .The therapy of SPT could control thyrotoxicosis quickly,reduce recurrence rate and lifelong hypothyroidism.
