title: Studies of the neutropenia in kala-azar: results in two patients.
abstract: Two patients with kala-azar were studied, one with DF32P (diisopropylfluorophosphate) and one with 51CR (chromate), in an attempt to elucidate the mechanisms producing neutropenia in this disease. The granulocyte half-life was found to be reduced in both patients, with pooling and probable destruction occurring in the spleen and, to a lesser extent, in the liver. Bone marrow neutrophil reserve, estimated by the response to intravenous hydrocortisone hemisuccinate, was found to be markedly reduced in both patients. An enlarged marginal granulocyte pool in one patient indicated that the neutropenia may also be due to altered intravascular granulocyte distribution.
