Univariate analysis (Table 2) showed that global mortality was associated whit older age (mean age 46.4 ± 8 vs 42.3 ± 9, p < 0.001), CDC stage C (51.6% vs 23.8%, p < 0.001), low CD4 cell count (393 ± 331 vs 523 ± 300, p = 0.005), HCV co-infection (46.8% vs 26.8%, p = 0.002) and injecting drug user (IDU) risk factor for HIV infection (48.4% vs 23.1%, p < 0.001). This evidence concerns the gene CD4 and coinfection.
