Abstract

Objectives: To estimate changes of AIDS and non-AIDS mortalities from 1996 to 2010 comparing (2004-2010) vs. (1996-2003) periods from the time of HIV-seroconversion (SC).

Methods: Data derived from an Italian multicentre prospective and open cohort; competing risks approach was applied estimating the cumulative incidence functions (CIF) for AIDS and non-AIDS deaths over time from SC with delayed entries in the two cART periods. Cox-cause-specific hazards models were applied to estimate relative hazards (RH) of AIDS and non-AIDS related deaths.

Results: Of 2,249 individuals with known SC date followed from SC and from January 1996 to December 2010, 1,779 were survived, seroconverted or followed during 1996-2003, while 1,715 during 2004-2010. A total of 278 deaths occurred from 1996 to 2010: 197 in the early years of cART [61 (31%) non-AIDS deaths], and 81 during more recent cART period [48 (59%) non-AIDS deaths]. The CIF of AIDS related deaths was higher than CIF of non-AIDS related deaths in the early period [for instance, estimates at 15 yrs from SC: CIF of AIDS-related death = 0.15 (95% CI: 0.12-0.19 ) and CIF of non-AIDS related = 0.09 (95% CI: 0.07-0.12)], whilst in 2004-2010 period the CIF of non-AIDS related deaths was slightly higher [estimates at 15 yrs from SC: CIF of non-AIDS related = 0.03 (95% CI: 0.02-0.04) vs. CIF of AIDS-related death = 0.02 (95% CI: 0.02-0.04)]. Comparing the two periods by Cox proportional-cause-specific models, the hazard was lower for AIDS deaths than for non-AIDS related deaths [RH of non-AIDS deaths from last viral load (VL) < 200 copies/mL was 0.60 (95% CI (0.35-1.03)], while of AIDS-deaths was 0.32 (95% CI: 0.17-0.62), both RH relative to (2004-2010) vs. (1996- 2003)].

Conclusions: Considering early years of the cART period as a reference, we observed a decrease in both AIDS and non-AIDS-mortalities. In more recent cART years, non-AIDS mortality tended to decline less than AIDS-relatedmortality since HIV-SC, even after effective cART.
