TI Pentoxifylline aggravates impairment in tumor necrosis factor-alpha
secretion and increases mycobacterial load in macrophages from AIDS
patients with disseminated Mycobacterium avium-intracellulare complex
infection.

AB Pentoxifylline, which inhibits tumor necrosis factor-alpha (TNF alpha),
decreases human immunodeficiency virus replication in peripheral blood
mononuclear cells. However, TNF alpha is important in cellular defense
against M. avium-intracellulare complex (MAC), a common infection in
advanced AIDS. The effect of pentoxifylline on mycobacterial colony
counts in macrophages with in vivo MAC infection was evaluated, and
differences in lipopolysaccharide (LPS)-induced TNF release in infected
and uninfected macrophages were determined. Macrophages with in vivo MAC
infection released much less TNF alpha in response to LPS (P = .01). The
response was partially restored after antimycobacterial therapy.
Pentoxifylline, in a concentration that inhibited LPS-induced TNF alpha
by 52.4%, increased MAC counts by 2.5- to 50.0-fold. Thus, macrophages
from AIDS patients with disseminated MAC infection are deficient in
their ability to release TNF alpha, and further inhibition by
pentoxifylline may be detrimental.
