title: Levels of proinflammatory cytokines in plasma after pneumoccoccal immunization in human immunodeficiency virus type 1-infected patients.
abstract: To ascertain if immunization with pneumococcal polysaccharide vaccine is associated with rises in the levels of proinflammatory cytokines in the plasma of human immunodeficiency virus type 1 (HIV-1)-infected patients, the levels of tumor necrosis factor alpha (TNF-alpha) and interleukin-6 (IL-6) were measured serially after immunization. IL-6 levels rose an average of 2.2- and 2.1-fold 6 and 8 h after immunization, respectively, but TNF-alpha levels remained unchanged. The levels of these cytokines were stable in unimmunized controls. Immunization with pneumococcal polysaccharide vaccine induces increases in the levels of IL-6 in the plasma of persons with HIV-1 infection.
