title: No effects of levamisole on cytotoxic drug-induced changes of human granulopoiesis.
abstract: The effect of Levamisole on the human granulopoiesis was studied in patients randomized to receive, in addition to adjuvant chemotherapy for primary breast cancer, either no other treatment or additional unspecific immune therapy with Levamisole. The reaction of granulopoiesis to the cytostatic drugs, as characterized by changes of peripheral blood polymorphonuclear neutrophils (PMN), functional bone marrow granulocyte reserve, serial bone marrow cytology, and granulopoietic stem cells (CFU-C) in marrow and blood, was not affected by administration of Levamisole. The data support the concept that Levamisole has no direct effect on human bone marrow granulopoiesis, but that an allergic mechanism is involved in the pathogenesis of Levamisole-induced agranulocytosis. The expectation that Levamisole exerts a beneficial effect by stimulation of the granulopoiesis, as previously suggested for BCG and Corynebacterium parvum, could not be substantiated in our studies.
