 AB    Two EIAs (Medgenix and Quantikine) and a bioassay were used to measure
       tumor necrosis factor-alpha (TNF alpha) in serum samples from 73 human
       immunodeficiency virus type 1 (HIV-1)-seropositive patients and in
       samples from 2 control groups. All clinical groups of HIV-1-infected
       patients, regardless of concurrent illness, had significantly elevated
       levels of both types of soluble TNF receptors (sTNFRs) and
       immunoreactive TNF alpha (Medgenix EIA), with the highest concentrations
       among the AIDS patients. These TNF parameters were significantly
       correlated with reduced CD4+ lymphocyte counts. Only a few
       HIV-1-infected patients had detectable TNF alpha levels measured by the
       Quantikine EIA. TNF alpha bioactivity was significantly raised only in
       the AIDS group. Serially measured sTNFRs, expressed as sTNFR slopes,
       were significantly associated with survival in the patient group. The
       raised levels of immunoreactive TNF alpha and sTNFRs strongly indicate
       activation of the TNF alpha system during HIV-1 infection. Levels
       increase with disease progression and degree of immunodeficiency; thus,
       serially measured sTNFRs may give useful prognostic information in HIV-1
       infection.
