Clinical situation of Venezuelan migrants living with HIV in a hospital in Lima, Peru.

Due to a huge crisis extensive to health services many Venezuelan people living with HIV (PLWH) had migrated abroad, including Peru where favorable laws were in place until June 2019. We describe the health status and epidemiological trends of PLWH from Venezuela at an HIV program in Lima. We analyzed baseline and follow-up data of all Venezuelan PLWH enrolled in our HIV program from January 2017 to December 2019. A cross-sectional study in a subsample served to describe ARV adherence and context of migration. Between 2017-2019 our HIV Program registered 398 Venezuelan PLWH, representing 20% of the 2018 annual enrollments; numbers decreased since mid-2019. The median age was 30 years (IQR 26;37) and 90.5% were men. Between 2017 and 2019, the proportion with diagnosis in Peru increased from 14.3% to 60.9%; of AIDS stage at entry, from 8.8% to 27.2%. By December 2019, 182/250 (72.8%) were still in care, and 43 (10.8%) had not started ART. Viral suppression evaluated in 195, was achieved in 71.8%. From 2017 to 2019, migrant PLWH arrived in worsened clinical conditions, with increasing diagnosis in Peru; the flow of migrant PLWH entering care diminished with less favorable laws. Viral suppression rates were suboptimal.

Early Retention in Care Neither Mediates Nor Modifies the Effect of Sex and Sexual Mode of HIV Acquisition on HIV Survival in the Americas.

Early 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.

Evaluating the care cascade after antiretroviral therapy initiation in Latin America.

Accelerating antiretroviral therapy (ART) administration, improving retention, and achieving viral suppression in low- and middle-income countries must be prioritized. We evaluated trends and disparities in these milestones in a large Latin American cohort. Adults starting ART (ARTstart) from 2003 to 2014 at Caribbean, Central, and South America network for HIV epidemiology sites were assessed for care cascade outcomes: CD4 cell count >200 cells/mm3 at ARTstart; retention (≥1 visit at one year after ARTstart); viral suppression (≥1 HIV-1 RNA <200 copies/ml at one year after ARTstart). Modified Poisson regression provided adjusted prevalence ratios by age, gender, and HIV transmission risk, accounting for site and year of ARTstart. Proportions achieving ARTstart and suppression improved over time (p < 0.05). Older age was associated with better retention and viral suppression, but not ARTstart at CD4 cell count >200 cells/mm3. Females and men who have sex with men (MSM) were more likely to have CD4 cell count >200 cells/mm3 at ARTstart. Injection drug users (IDUs) were less likely to be retained while MSM were more likely to achieve viral suppression (all p < 0.05). Despite improvements in these outcomes over the course of a decade in this cohort, significant disparities existed, disadvantaging younger patients, men, and IDUs. These gaps indicate continued progress in providing early diagnosis and ARTstart remain critical.

Insulin resistance by homeostasis model assessment in HIV-infected patients on highly active antiretroviral therapy: cross-sectional study.

BACKGROUND: The highly active antiretroviral therapy (HAART) has altered the course of HIV infection, transforming it from a fatal illness to a chronic condition, reducing morbidity and mortality. However, this therapy has led to an increased incidence of metabolic problems such as insulin resistance, dyslipidemia, lipodystrophy and impaired glucose metabolism. The objectives of this study are to determine the prevalence of insulin resistance (IR) in a cohort of human immunodeficiency virus (HIV)-infected patients on highly active antiretroviral therapy (HAART) and to investigate the potentially associated factors. METHODS: We conducted a cross-sectional study including 219 adult patients with HIV on HAART. IR was determined through the homeostasis model assessment (HOMA-IR) mathematical model, using fasting plasma glucose (FPG) and insulin. Bivariate and multivariate analyses were performed to assess the association between demographic information, clinical characteristics and laboratory results, and IR. RESULTS: 75 (34.2 %) [95 % confidence interval (CI) 28.9-40.9] HIV-patients on HAART showed IR. 61 (81 %) of these patients were on HAART for more than one year, which was mainly composed by non-protease inhibitors drugs (88 %). Metabolic syndrome (MS) was found in 59 (26.9 %) subjects. In the multivariate analysis, the factors associated with IR were age ≥ 46 years (Prevalence ratio = 2.767, 95 % CI 1.325 to 5.780) and greater body mass index (BMI) (Prevalence ratio = 1.148, 95 % CI 1.054 to 1.250). CONCLUSIONS: The prevalence of IR was 34.2 %. Factors associated with IR were age and BMI. We did not find any significant association between IR and protease inhibitors (PI), which may be explained by the small number of patients using PI as part of their HAART regimen included in our study.
