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.
为了确定肺炎球菌多糖疫苗免疫接种是否与1型人类免疫缺陷病毒(HIV-1)感染患者血浆中促炎细胞因子水平升高有关,在免疫接种后连续测量肿瘤坏死因子α(TNF-α)和白细胞介素-6(IL-6)的水平。免疫接种后6小时和8小时,IL-6水平分别平均升高2.2倍和2.1倍,但TNF-α水平保持不变。在未免疫的对照中,这些细胞因子的水平是稳定的。肺炎球菌多糖疫苗免疫接种可导致HIV-1感染人群血浆中IL-6水平升高。
