The European Multicentre Trial Group has investigated the effects of methimazole drug dose on the long\u2010term outcome of Graves' disease.<\/jats:p><\/jats:sec><jats:sec><jats:title>DESIGN<\/jats:title><jats:p>Extended follow\u2010up of patients from a prospective multicentre trial, designed to study methimazole dose effects on the outcome of Graves' disease. We have reported previously that the relapse rates did not differ after a medication\u2010free observation period of 12 months; the relapse rates were 37 and 38%, respectively. In this paper, we describe the outcome in these patients after a mean observation period of 4.3\u2003\u00b1\u20031.3 years and have looked for potential predictors of this outcome.<\/jats:p><\/jats:sec><jats:sec><jats:title>PATIENTS<\/jats:title><jats:p>Three hundred and thirteen patients with Graves' disease were randomized to treatment with a constant dose of 10 or 40\u2003mg of methimazole for 1 year, with levothyroxine supplementation as required.<\/jats:p><\/jats:sec><jats:sec><jats:title>MEASUREMENTS<\/jats:title><jats:p>At the time of inclusion into the trial: thyroid size, T4, T3, TSH\u2010binding inhibiting immunoglobulins, urinary iodide excretion, thyroid uptake, Crook's therapeutic index of hyperthyroidism (a measure of clinical disease severity). At the time of follow\u2010up examination: TSH, T4, T3, thyroid size, thyroid ultrasound, THS\u2010binding inhibiting immunoglobulins.<\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS<\/jats:title><jats:p>The overall relapse rate was 58%. There was no difference in relapse rates between patients treated with either 10 or 40\u2003mg of methimazole (58.3 <jats:italic>vs.<\/jats:italic> 57.8%). Five patients had become spontaneously hypothyroid, without obvious relationship to antithyroid drug dose. Patients who relapsed and patients who remained in remission did not differ with respect to: age, goitre size, ophthalmopathy, median iodine excretion, serum T4 or serum T3, Crook's therapeutic index and thyroid uptake at the time of study entry. Thus, none of these variables was potentially suitable for predicting outcome. This finding was confirmed by Cox's proportional hazard regression. Thyroid volume, measured by ultrasound, did not differ between patients in remission and patients with relapse. There was no difference in the course of endocrine eye signs, in the requirement for steroid and radiotherapy for eye signs, or in thyroid echostructure between patients in the 10 and in the 40\u2003mg group, nor was serum TSH different in patients who had remained in remission (0.8\u2003\u00b1\u20030.6\u2003mU\/l in the 10\u2003mg group, 1.0\u2003\u00b1\u20030.8\u2003mU\/l in the 40\u2003mg group).<\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSIONS<\/jats:title><jats:p>The dose of methimazole in Graves' disease therapy can safely be kept to the minimal required dose.
