The levels of soluble Fas/Apo-1(CD95) -antigene (sFas/Apo-1(CD95)) and Fas-ligand (sFasL) in blood serum of HIV-infected patients and healthy persons have been evaluated. The results showed that, significantly high sFas/ Apo-1(CD-95) and sFasL concentrations came to light in blood serum of HIV-infected patients in comparison with healthy persons (р <0,001). The direct correlation between sFas/Apo-1(CD-95) concentration and HIV-infection stage established clinically (R=0,414, р=0,002) and immunologically (R=0,676, р<0,001), and also return correlation between sFasL concentration and a HIV-infection stage established immunologically (R =-0,468, р <0,001) have been revealed. The significantly higher sFas/Apo-1(CD-95) serum concentration (р<0,001) and significantly lower sFasL concentration (p=0,001) have been revealed in patients in AIDS stage, in comparison with patients not in AIDS stage. In patients with CD4-cells quantity less than 350/html5-dom-document-internal-entity2-956-endl of blood the sFas/Apo-1(CD-95) serum concentration was significantly above (р<0,001), and sFasL concentration - is significant more low (р=0,039), than in patients with CD4-cells quantity more than 350/html5-dom-document-internal-entity2-956-endl of blood.
