HIV-related Excess Mortality and Age-Related Comorbidities in Patients with HIV Aged ≥60: a Relative Survival Analysis in the French Dat'AIDS Cohort.

OBJECTIVE:The objective was to evaluate the association between age-related comorbidities (ARCs) and 5-year HIV-related excess mortality in people living with HIV aged ≥60 years.DESIGN:Cohort study using relative survival analysis (Estève's model).SETTING:The French multicentre prospective Dat'AIDS cohort that involves 12 French hospitals.PARTICIPANTS:Inclusion of 1415 HIV-1 infected patients actively followed aged ≥60 years on January 2008, with a 5-year follow-up period in the late combination antiretroviral therapy era.RESULTS:Among 1415 patients included, 154 died. By multivariable analysis, factors predictive of 5-year HIV-related excess mortality were non-AIDS-related cancer (adjusted excess HR (aEHR)=2.94; 95% CI 1.32 to 6.57), cardiovascular disease (aEHR=6.00; 95% CI 2.45 to 14.65), chronic renal disease (aEHR=4.86; 95% CI 2.24 to 10.53), cirrhosis (aEHR=3.58; 95% CI 1.25 to 10.28), hepatitis C co-infection (aEHR=3.63; 95% CI 1.44 to 9.12), body mass index<18.5 kg/m² (aEHR=4.10; 95% CI 1.61 to 10.48) and having a CD4 cell count ≤200/mm3 (aEHR=5.79; 95% CI 2.28 to 14.69).CONCLUSIONS:ARCs, particularly cardiovascular disease and chronic renal disease, are predictive of HIV-related excess mortality, with an increase in hazard similar to that of CD4 cell count.TRIAL REGISTRATION NUMBER:NCT02898987.
