 AB    Tumor necrosis factor-alpha (TNF) may activate human immunodeficiency
       virus (HIV), antagonize zidovudine activity, and contribute to AIDS
       wasting syndrome. Pentoxifylline decreases TNF production. In cell
       culture, pentoxifylline decreases HIV replication and gene expression.
       Since an AIDS Clinical Trial Group study suggested that pentoxifylline
       (400 mg thrice daily) is safe in AIDS patients and decreases TNF mRNA
       levels in peripheral blood mononuclear cells (PBMC), a second cohort
       received 800 mg thrice daily for 8 weeks. During treatment, the median
       decrease in TNF production by PBMC cultured with 0.1 microgram/mL
       lipopolysaccharide (LPS) was 40%. The median change in TNF mRNA was a
       34% decrease. Pentoxifylline did not affect HIV levels as detected by
       quantitative microculture or serum p24 antigen measurements, nor did it
       alter zidovudine pharmacokinetics. The most common toxicity was
       gastrointestinal. Pentoxifylline at dosages of less than thrice-daily
       800 mg is well tolerated and may decrease TNF mRNA levels and
       LPS-induced TNF production.
