[Serum thyroid hormones in hyperthyroid patients treated with carbimazole (author's transl)]

Serum thyroxine (T4), triiodothyronine (T3) and thyrotropin (T.S.H.) were measured in 32 hyperthyroid patients treated with carbimazole. A discrepancy between serum T4 AND T3 was present in 73 of 131 measurements: --normal T3 with increased T4 in 6 measurements; --increased T3 with normal T4 in 16 measurements: five times only there was a clinical hyperthyroidism; --normal T3 with decreased T4 in 49 measurements: three times only there was a clinical hypothyroidism. Serum T.S.H. level was increased in 13 of 19 measurements made in this group, state named "compensated hypothyroidism" according to Patel and Burger.
