Trends in life expectancy of HIV-positive adults on antiretroviral therapy across the globe: comparisons with general population.

ABSTRACT: Improved virological and immunological outcomes and reduced toxicity of antiretroviral combination therapy (ART) raise the hope that life expectancy of HIV-positive persons on ART will approach that of the general population. We systematically review the literature and summarize published estimates of life expectancy of HIV-positive populations on ART. We compare their life expectancy with the life expectancy of the general or, in sub-Saharan Africa, HIV-negative populations, by time period and gender.Ten relevant studies were published from 2006 to 2015. Three studies were from Canada, two from European countries, three from sub-Saharan Africa and two were multicountry studies. Life expectancy increased over time in all studies and regions. Expressed as the percentage of life expectancy in the HIV-negative or general population, estimated life expectancy at age 20 years in HIV-positive people on ART ranged from 60.3% (95% CI 58.0-62.6%) in Rwanda (2008-2011) to 89.1% (95% CI 84.7-93.6%) in Canada (2008-2012). The percentage of life expectancy in the HIV-negative or general population achieved was higher in HIV-positive women than in HIV-positive men in all countries, except for Canada wherein the opposite was the case.Life expectancy in HIV-positive people on ART has improved worldwide in recent years, but important gaps remain compared with the general and HIV-negative population, and between regions and genders.

Project description:BackgroundThere are few data on life expectancy gains among people living with HIV in low-income and middle-income settings where antiretroviral therapy (ART) is increasingly available. We aimed to analyse life expectancy trends from 2003 to 2017 among people with HIV beginning treatment with ART within the Caribbean, central America, and South America.MethodsWe did a multisite retrospective cohort study and included people with HIV who had started treatment with ART and were aged 16 years or older between Jan 1, 2003, and Dec 31, 2017, from Caribbean, Central and South America network for HIV epidemiology (CCASAnet) sites in Argentina, Brazil, Chile, Haiti, Honduras, Mexico, and Peru, who contributed person-time data from the age of 20 years until date of death, last contact, database closure, or Dec 31, 2017. We used the Chiang method of abridged life tables to estimate life expectancy at age 20 years for three eras (2003-08, 2009-12, and 2013-17) overall and by demographic and clinical characteristics at ART initiation. We used Poisson regression models to weight mortality rates to account for informative censoring.Findings30 688 people with HIV were included in the study; 17 491 (57·0%) were from the Haiti site and 13 197 (43·0%) were from all other sites. There were 2637 deaths during the study period: 1470 in Haiti and 1167 in other sites. Crude and weighted mortality rates decreased among all age groups over calendar eras. From 2003-08 to 2013-17, overall life expectancy for people with HIV at age 20 years increased from 13·9 years (95% CI 12·5-15·2) to 61·2 years (59·0-63·4) in Haiti and from 31·0 years (29·3-32·8) to 69·5 years (67·2-71·8) in other sites. Life expectancies at the end of the study period were within 10 years of those of the general population (69·9 years in Haiti and 78·0 years in all other sites in 2018). Disparities in life expectancy among people with HIV by sex or HIV transmission risk factor, CD4 cell count, level of education, and history of tuberculosis at or before ART initiation persisted across calendar eras.InterpretationLife expectancy among people with HIV receiving ART has significantly improved in Latin America and the Caribbean. Persistent disparities in life expectancy among people with HIV by demographic and clinical factors at ART initiation highlight vulnerable populations in the region.FundingNational Institutes of Health.TranslationFor the Spanish translation of the abstract see Supplementary Materials section.

Project description:Cardiovascular disease and non-AIDS malignancies have become major causes of death among HIV-infected individuals. The relative impact of lifestyle and HIV-related factors are debated.We estimated associations of smoking with mortality more than 1 year after antiretroviral therapy (ART) initiation among HIV-infected individuals enrolled in European and North American cohorts. IDUs were excluded. Causes of death were assigned using standardized procedures. We used abridged life tables to estimate life expectancies. Life-years lost to HIV were estimated by comparison with the French background population.Among 17,995 HIV-infected individuals followed for 79,760 person-years, the proportion of smokers was 60%. The mortality rate ratio (MRR) comparing smokers with nonsmokers was 1.94 [95% confidence interval (95% CI) 1.56-2.41]. The MRRs comparing current and previous smokers with never smokers were 1.70 (95% CI 1.23-2.34) and 0.92 (95% CI 0.64-1.34), respectively. Smokers had substantially higher mortality from cardiovascular disease, non-AIDS malignancies than nonsmokers [MRR 6.28 (95% CI 2.19-18.0) and 3.31 (95% CI 1.80-5.45), respectively]. [corrected]. Among 35-year-old HIV-infected men, the loss of life-years associated with smoking and HIV was 7.9 (95% CI 7.1-8.7) and 5.9 (95% CI 4.9-6.9), respectively. The life expectancy of virally suppressed, never-smokers was 43.5 years (95% CI 41.7-45.3), compared with 44.4 years among 35-year-old men in the background population. Excess MRRs/1000 person-years associated with smoking increased from 0.6 (95% CI -1.3 to 2.6) at age 35 to 43.6 (95% CI 37.9-49.3) at age at least 65 years.Well treated HIV-infected individuals may lose more life years through smoking than through HIV. Excess mortality associated with smoking increases markedly with age. Therefore, increases in smoking-related mortality can be expected as the treated HIV-infected population ages. Interventions for smoking cessation should be prioritized.
