    Abstract

    The effect of a single bolus injection (0.4 g/kg) of intravenous immunoglobulin (IVIG) on the tumor necrosis factor (TNF) system in human immunodeficiency virus type 1 (HIV-1)-infected patients was investigated. At 140 h after infusion, there was a significant decrease in levels of TNF-alpha and a significant increase in levels of soluble TNF receptors (sTNFR) in both plasma and lipopolysaccharide-stimulated peripheral blood mononuclear cells (PBMC). A rapid (within 1 h) decline in expression of membrane-bound TNF-alpha and p55-TNFR on PBMC persisted throughout the study. In contrast, there was an increased expression of membrane-bound p75-TNFR after 140 h. IVIG administration also resulted in significantly increased numbers of circulating CD4 lymphocytes, correlated with down-regulation of TNF-alpha activity in PBMC supernatants. Thus, down-regulation of the abnormally increased TNF-alpha activity may be achieved by IVIG administration. Studies evaluating the possible therapeutic role of long-term TNF-alpha suppression by IVIG may be warranted in HIV-1-infected patients.
