Immunomodulatory treatment of Mycobacterium avium complex bacteremia in patients with AIDS by use of recombinant granulocyte-macrophage colony-stimulating factor 35th Interscience Conference on Antimicrobial Agents and Chemotherapy Kemper, C.

Abstract

Eight AIDS patients with Mycobacterium avium complex (MAC) bacteremia were randomized to receive azithromycin with or without granulocyte-macrophage colony-stimulating factor (GM-CSF) for 6 weeks to examine the effect of GM-CSF administration on clearance of mycobacteremia and on monocyte function. Superoxide anion production was significantly increased ex vivo in monocytes from patients receiving GM-CSF but not in those from patients receiving azithromycin alone. Relative to monocytes obtained from untreated healthy controls, median differences in viable intracellular MAC at 2, 4, and 6 weeks were -0.76, -0.94, and -0.47 log10 cfu/mL of lysate for cells from patients receiving GM-CSF versus -0.15, -0.11, and -0.19 log10 cfu/mL for cells from patients receiving azithromycin alone. Although no effect on mycobacteremia was detected, the administration of GM-CSF to AIDS patients with MAC bacteremia resulted in activation of their blood monocytes, as evidenced by increased superoxide anion production and enhanced mycobactericidal activity. GM-CSF deserves further investigation in the treatment of mycobacterial infections.
