CONTEXT: Drug-based therapy is usually the initial treatment for Graves’ disease
(GD) hyperthyroidism in children, but there is some debate about treatment
OBJECTIVE: Our objective was to assess the effect of long-term carbimazole
therapy on GD remission in children and its determinants.
DESIGN AND SETTING: This was an observational prospective multicenter follow-up
cohort study.
PARTICIPANTS: Participants included 154 children newly diagnosed with GD between
1997 and 2002. The intention was to treat patients with three consecutive courses
of carbimazole, each lasting 2 yr. Definitive treatment was performed in cases of
poor compliance with antithyroid drug (ATD) treatment, thyrotoxicosis relapse, or
major adverse effects of ATD treatment.
MAIN OUTCOME MEASURE: The main outcome measure was remission for at least 18
months after the completion of each course of ATD treatment.
RESULTS: The median duration of follow-up was 10.4 (9.0-12.1) yr. Overall
estimated remission rates (95% confidence interval) 18 months after the
withdrawal of ATD treatment increased with time and were 20 (13-26), 37 (29-45),
45 (35-54), and 49 (40-57)% after 4, 6, 8, and 10 yr follow-up, respectively. A
multivariate competing risk model revealed an independent positive effect of less
severe forms of hyperthyroidism at diagnosis [subhazard ratio of 1 for patients
