BACKGROUND: Outcomes of community-acquired pneumonia (CAP) in relation to CD4+ cell counts have not been established. We examined the correlation of CD4+ cell count and HIV-RNA level with the clinical outcomes of CAP in hospitalized HIV-infected patients. METHODS: This was a retrospective study of 127 adult hospitalized patients with HIV infection enrolled with the CAP Organization (CAPO), examining the time to clinical stability (TCS), length of hospital stay (LOS), and all-cause mortality. RESULTS: Mortality data were available for 117 HIV-infected patients with CAP. Death within 28 days was reported in 28 patients. The risk of mortality at 28 days was not significant when adjusted for CD4+ cell count (p=0.123), HIV-RNA <400-1000 copies/ml (p=0.093), HIV-RNA ≥ 1000-10,000 copies/ml (p=0.543), and HIV-RNA ≥ 10,000-100,000 copies/ml (p=0.383). The propensity-adjusted Cox proportional hazards regression models did not show any statistically significant differences in LOS or TCS for CD4+ cell counts (p=0.590 and p=0.420, respectively) or HIV-RNA levels (p=0.470 and p=0.080, respectively). Multivariable Cox proportional hazards models did not reveal any statistically significant relationships between CD4+ cell counts or HIV-RNA levels with LOS or TCS. CONCLUSIONS: Our study shows that clinical outcomes of HIV-infected patients with CAP are not predicted by CD4+ cell counts or HIV-RNA levels after adjusting for confounders. The management of CAP in patients with HIV infection should not be based on CD4+ cell counts or HIV-RNA levels of the HIV infection.
