    Frequency of non-communicable diseases in people 50 years of age and older receiving HIV care in Latin America
    (2020-06-17) Belaunzaran-Zamudio, Pablo F; Caro-Vega, Yanink; Giganti, Mark J; Castilho, Jessica L; Crabtree-Ramirez, Brenda E; Shepherd, Bryan E; Mejía, Fernando; Cesar, Carina; Moreira, Rodrigo C; Wolff, Marcelo; Pape, Jean W; Padgett, Denis; McGowan, Catherine C; Sierra-Madero, Juan G; for the Caribbean, Central and South American network for HIV epidemiology (CCASAnet)
    Background A growing population of older adults with HIV will increase demands on HIV-related healthcare. Nearly a quarter of people receiving care for HIV in Latin America are currently 50 years or older, yet little is known about the frequency of comorbidities in this population. We estimated the prevalence and incidence of non-communicable diseases (NCDs) among people 50 years of age or older (≥50yo) receiving HIV care during 2000–2015 in six centers affiliated with the Caribbean, Central and South American network for HIV epidemiology (CCASAnet). Methods We estimated the annual prevalence, and overall prevalence and incidence of cardiovascular diseases, diabetes, hypertension, dyslipidemia, psychiatric disorders, chronic liver and renal diseases, and non-AIDS-defining cancers, and multimorbidity (more than one NCD) of people ≥50yo receiving care for HIV. Analyses were performed according to age at enrollment into HIV care (<50yo and ≥50yo). Results We included 3,415 patients ≥50yo, of whom 1,487(43%) were enrolled at age ≥50 years. The annual prevalence of NCDs increased from 32% to 68% and multimorbidity from 30% to 40% during 2000–2015. At the last registered visit, 53% of patients enrolled <50yo and 50% of those enrolled ≥50yo had at least one NCD. Most common NCDs at the last visit in each age-group at enrollment were dyslipidemia (36% in <50yo and 28% in ≥50yo), hypertension (17% and 18%), psychiatric disorders (15% and 10%), and diabetes (11% and 12%). Conclusions The prevalence of NCDs and multimorbidity in people ≥50 years receiving care for HIV in CCASAnet centers in Latin America increased substantially in the last 15 years. Our results make evident the need of planning for provision of complex, primary care for aging adults living with HIV.

    Incidence of virological failure and major regimen change of initial combination antiretroviral therapy in Latin America and the Caribbean: an observational cohort study
    (2015-11) Cesar, Carina; Jenkins, Cathy A.; Shepherd, Bryan E.; Padgett, Denis; Mejía, Fernando; Rocha Ribeiro, Sayonara; Cortes, Claudia; Pape, Jean W; Sierra Madero, Juan; Fink, Valeria; Sued, Omar; McGowan, Catherine C.; Cahn, Pedro; Caribbean; Central and South America Network for HIV Epidemiology (CCASAnet) of the International Epidemiologic Databases to Evaluate AIDS (IeDEA) Program
    Background: Access to combination antiretroviral therapy (ART) is expanding in Latin America (Mexico, Central America, and South America) and the Caribbean. We assessed the incidence of and factors associated with regimen failure and regimen change of initial ART in this region. Methods: This observational cohort study included antiretroviral-naive adults starting ART from 2000 to 2014 at sites in seven countries throughout Latin America and the Caribbean. Primary outcomes were time from ART initiation until virological failure, major regimen modification, and a composite endpoint of the first of virological failure or major regimen modification. Cumulative incidence of the primary outcomes was estimated with death considered a competing event. Findings: 14,027 patients starting ART were followed up for a median of 3.9 years (2.0-6.5): 8374 (60%) men, median age 37 years (IQR 30-44), median CD4 count 156 cells per μL (61-253), median plasma HIV RNA 5.0 log10 copies per mL (4.4-5.4), and 3567 (28%) had clinical AIDS. 1719 (12%) patients had virological failure and 1955 (14%) had a major regimen change. Excluding the site in Haiti, which did not regularly measure HIV RNA, cumulative incidence of virological failure was 7.8% (95% CI 7.2-8.5) 1 year after ART initiation, 19.2% (18.2-20.2) at 3 years, and 25.8% (24.6-27.0) at 5 years; cumulative incidence of major regimen change was 5.9% (5.3-6.4) at 1 year, 12.7% (11.9-13.5) at 3 years, and 18.2% (17.2-19.2) at 5 years. Incidence of major regimen change at the site in Haiti was 10.7% (95% CI 9.7-11.6) at 5 years. Virological failure was associated with younger age (adjusted hazard ratio [HR] 2.03, 95% CI 1.68-2.44, for 20 years vs 40 years), infection through injection drug use (vs infection through heterosexual sex; 1.60, 1.02-2.52), and initiation in earlier calendar years (1.28, 1.13-1.46, for 2002 vs 2006), but was not significantly associated with boosted protease inhibitor-based regimens (vs non-nucleoside reverse transcriptase inhibitor; 1.17, 1.00-1.36). Interpretation: Incidence of virological failure in Latin America and the Caribbean was generally lower than that reported in North America or Europe. Our results suggest the need to design strategies to reduce failure and major regimen change in young patients and those with a history of injection drug use.
