Popis: The early (20-minute) radioiodine uptake has been used to follow the month by month variations in thyroid stimulation occurring in 35 Graves' disease patients treated with carbimazole and T3 for a period of 18 months. T3 alone (classical suppression test) produced no change in mean uptake, but 4 weeks after the introduction of carbimazole, the mean uptake had fallen from 21.6% to 13.4% of the dose (P < 0.001). Over the subsequent 17 months, the mean uptake fell further to 8% (P < 0.05). Six months after withdrawal of treatment, 20 patients (group R) had relapsed and 15 (group E) had remained euthyroid. The only difference in mean uptake behavior between R and E patients was one of degree, their slopes being similar. Thus while the mean uptake of both groups fell progressively towards normal, that of group E patients arrived much earlier. The uptake in 16 patients fell by greater than 50% by month 2, and 10 of them were from group E. In the remaining 19 patients, the uptake fell less rapidly: only 5 of the...
