Abstract
Agranulocytosis is the most serious side effect of antithyroid drug (ATD) therapy. We conducted prospective and randomized studies to examine whether granulocyte colony-stimulating factor (G-CSF) is actually effective for ATD-induced agranulocytosis. Twenty-four patients with Graves' disease who developed agranulocytosis during ATD therapy were randomly divided into a G-CSF group (n = 14) and an untreated group (n = 10). Subcutaneous injection of G-CSF (100 to 250 μg) was given daily until neutrophil counts rose to greater than 1000/μL. The untreated group received antibiotic therapy only. Recovery time, which is defined as the number of days required for neutrophil counts to exceed 500/μL, was monitored by daily complete blood count (CBC). Recovery time in the G-CSF-treated group did not differ from that of the untreated group in those patients with moderate and severe agranulocytosis; thus, prolonged use of G-CSF treatment is generally ineffective for ATD-induced agranulocytosis.Keywords
