Item Antiretroviral therapy and Kaposi’s sarcoma trends and outcomes among adults with HIV in Latin America(2021-01-06) Castilho, Jessica L; Kim, Ahra; Jenkins, Cathy a; Grinsztejn, Beatriz; Gotuzzo, Eduardo; Fink, Valeria; Padgett, Denis; Belaunzaran-Zamudio, Pablo F; Crabtree-Ramírez, Brenda; Escuder, Maria Mercedes; Souza, Rosa Alencar; Tenore, Simone B; Pimentel, Sidnei R; Rodrigues Ikeda, Maria Letícia; de Alencastro, Paulo R; Tupinanbas, Unai; Brites, Carlos; Luz, Estela; Netto, Juliana; Cortes, Claudia; Grangeiro, Alexandre; Shepherd, Bryan E; McGowan, Catherine C; The Caribbean, Central, South America network for HIV Epidemiology (CCASAnet)Abstract Introduction Kaposi’s sarcoma (KS) remains the most frequent malignancy in persons living with HIV (PWH) in Latin America. We examined KS trends and outcomes from Latin American clinical sites in the era of increased access to antiretroviral therapy (ART). Methods Cohorts in Brazil, Peru, Mexico, Honduras, Argentina and Chile contributed clinical data of PWH ≥16 years old from 2000 to 2017, excluding patients with KS diagnosed before clinic enrolment. We compared KS incidence over time using multivariable incidence rate ratios. Predictors of KS before/at or after ART initiation and of mortality after KS were examined using Cox regression. Results Of 25 981 PWH, 481 had incident KS, including 200 ART-naïve and 281 ART-treated patients. From 2000 to 2017, the incidence of KS decreased from 55.1 to 3.0 per 1000 person-years. In models adjusting for CD4 and other factors, the relative risk for KS decreased from 2000 to 2008. Since 2010, the adjusted risk of KS increased in the periods before and ≤90 days after ART initiation but decreased >90 days after ART. In addition to low CD4 and male-to-male sex, KS risk after ART was associated with age and history of other AIDS-defining illnesses. Mortality after KS (approximately 25% after five years) was not associated with either year of KS diagnosis nor timing of diagnosis relative to ART initiation. Conclusions KS incidence in Latin America has remained stable in recent years and risk is highest before and shortly after ART initiation. Early diagnosis of HIV and ART initiation remain critical priorities in the region.Item Early Retention in Care Neither Mediates Nor Modifies the Effect of Sex and Sexual Mode of HIV Acquisition on HIV Survival in the Americas(https://doi.org/10.1089/apc.2018.0028, 2018-08-01) Coelho, Lara; Rebeiro, Peter F; Castilho, Jessica L; Caro-Vega, Yanink; Mejia, Fernando A; Cesar, Carina; Cortes, Claudia; Padgett, Denis; McGowan, Catherine C; Veloso, Valdiléa G; Sterling, Timothy R; Grinsztejn, Beatriz; Shepherd, Bryan E; Luz, Paula M; for the CCASAnetEarly retention in care, sex, and sexual mode of HIV acquisition has been associated with mortality risk among persons living with HIV (PLWH). We assessed whether early retention in care mediates or modifies the association between mortality and sex and sexual mode of HIV acquisition among PLWH on antiretroviral therapy (ART) in the Americas. ART-naïve, adult PLWH (≥18 years) enrolling at Caribbean, Central and South America network for HIV epidemiology (CCASAnet) and Vanderbilt Comprehensive Care Clinic sites 2000–2015, starting ART, and with ≥1 visit after ART-start were included. Early retention in care was defined as ≥2 HIV care visits/labs ≥90 days apart in the first year of ART. Cox models assessed the association between early retention in care, sex, and sexual mode of HIV acquisition [i.e., women, heterosexual men and men who have sex with men (MSM)], and mortality. Associations were estimated separately by site and pooled. Among 11,721 included PLWH (median follow-up, 4.3 years; interquartile range, 2.0–7.6), 647 died (rate = 10.9/1000 person-years) and 1985 were lost to follow-up (rate = 33.6/1000 person-years). After adjustment for confounders, early retention in care was associated with lower mortality during subsequent years (pooled hazard ratio = 0.47; 95% confidence interval = 0.39–0.57). MSM had lower and heterosexual men had comparable mortality risk to women; risks were similar when adjusting for early retention in care. Additionally, no evidence of an interaction between early retention in care and sex and sexual mode of HIV acquisition on mortality was observed (p > 0.05). Early retention in care substantially reduced mortality but does not mediate or modify the association between sex and sexual mode of HIV acquisition and mortality in our population.Item 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.Item Survival after cancer diagnosis in a cohort of HIV-positive individuals in Latin America(2018-05-08) Fink, Valeria; Jenkins, Cathy A; Castilho, Jessica L; Person, Anna K; Shepherd, Bryan E; Grinsztejn, Beatriz; Netto, Juliana; Crabtree-Ramirez, Brenda; Cortes, Claudia; Padgett, Denis; Jayathilake, Karu; McGowan, Catherine; Cahn, PedroBackground This study aimed to evaluate trends and predictors of survival after cancer diagnosis in persons living with HIV in the Caribbean, Central, and South America network for HIV epidemiology cohort. Methods Demographic, cancer, and HIV-related data from HIV-positive adults diagnosed with cancer ≤ 1 year before or any time after HIV diagnosis from January 1, 2000-June 30, 2015 were retrospectively collected. Cancer cases were classified as AIDS-defining cancers (ADC) and non-AIDS-defining cancers (NADC). The association of mortality with cancer- and HIV-related factors was assessed using Kaplan-Meier curves and Cox proportional hazards models stratified by clinic site and cancer type. Results Among 15,869 patients, 783 had an eligible cancer diagnosis; 82% were male and median age at cancer diagnosis was 39 years (interquartile range [IQR]: 32–47). Patients were from Brazil (36.5%), Argentina (19.9%), Chile (19.7%), Mexico (19.3%), and Honduras (4.6%). A total of 564 ADC and 219 NADC were diagnosed. Patients with NADC had similar survival probabilities as those with ADC at one year (81% vs. 79%) but lower survival at five years (60% vs. 69%). In the adjusted analysis, risk of mortality increased with detectable viral load (adjusted hazard ratio [aHR] = 1.63, p = 0.02), age (aHR = 1.02 per year, p = 0.002) and time between HIV and cancer diagnoses (aHR = 1.03 per year, p = 0.01). Conclusion ADC remain the most frequent cancers in the region. Overall mortality was related to detectable viral load and age. Longer-term survival was lower after diagnosis of NADC than for ADC, which may be due to factors unrelated to HIV.
