Individuell dosiertes Levothyroxin mit 150 µg Jodid versus 100 µg Levothyroxin kombiniert mit 100 µg Jodid: Eine randomisierte Doppelblindstudie

BASIC PROBLEM AND OBJECTIVE Intrathyroid deficiency and the influence of thyroid stimulating hormone (TSH) are the main pathogenetic factors in the development of endemic euthyroid goitre. Goitre reduction is achieved with either administration of levothyroxine, which diminishes hypophyseal TSG production, or of iodide. Aim of this study was to compare the efficacy of treatment with a dose-fixed combination of levothyroxine plus iodide with that of an individualized dosage of levothyroxine plus iodide. PATIENTS AND METHODS After randomization 49 patients with euthyroid goitre (24 women, 25 men, aged 20-43 years) were treated for 12 weeks in a double-blind trial. Patients in group A received…
