Mortality, Causes of Death and Associated Factors Relate to a Large HIV Population-Based Cohort

INTRODUCTION:
Antiretroviral therapy has led to a decrease in HIV-related mortality and to the emergence of non-AIDS defining diseases as competing causes of death. This study estimates the HIV mortality rate and their risk factors with regard to different causes in a large city from January 2001 to June 2013.

MATERIALS AND METHODS:
We followed-up 3137 newly diagnosed HIV non-AIDS cases. Causes of death were classified as HIV-related, non-HIV-related and external. We examined the effect of risk factors on survival using mortality rates, Kaplan-Meier plots and Cox models. Finally, we estimated survival for each main cause of death groups through Fine and Gray models.

MORTALITY RESULTS:
182 deaths were found [14.0/1000 person-years of follow-up (py); 95% confidence interval (CI):12.0-16.1/1000 py], 81.3% of them had a known cause of death. Mortality rate by HIV-related causes and non-HIV-related causes was the same (4.9/1000 py; CI:3.7-6.1/1000 py), external was lower [1.7/1000 py; (1.0-2.4/1000 py)].

SURVIVAL RESULTS:
Kaplan-Meier estimate showed worse survival in intravenous drug user (IDU) and heterosexuals than in men having sex with men (MSM). Factors associated with HIV-related causes of death include: IDU male and <200 CD4 at diagnosis versus ≥500 CD4. 

Factors associated with non-HIV-related causes of death include: ageing and heterosexual female versus MSM. Factors associated with external causes of death were IDU male and heterosexual male versus MSM.
