Abstract
A patient who developed agranulocytosis following exposure to 3 drugs: amodiaquine, pyrimethamine and dipyrone was reported. The combination of amodiaquine with the patient''s serum, obtained during the agranulocytosis, inhibited in vitro granulocyte-monocyte colony-forming unit (CFU-GM) growth of autologous and allogeneic marrow. Amodiaquine-induced agranulocytosis is apparently immune in nature. This in vitro approach may be used to study the mechanism of drug-induced agranulocytosis, especially when patients are exposed to multiple drugs.
