Is substance use associated with HIV cascade outcomes in Latin America?

ABSTRACT: The HIV care cascade has improved in Latin America over the last decade. However, the influence of alcohol and noninjected drug use (NIDU) on cascade outcomes is mostly unknown. This study estimated the association of alcohol and NIDU with retention in care, loss to follow up (LTFU), and virologic failure (VF).Individuals ?18 years attending routine HIV clinic visits and completing the Rapid Screening Tool (RST; evaluating NIDU and ART adherence in 7-day recall period) during 2012-13 were followed up to 2015 in the Caribbean, Central and South America network for HIV epidemiology. Adjusted odds ratios (aOR) were calculated for the association of alcohol consumption and NIDU with retention in care by logistic regression; adjusted hazard ratios (aHR) were estimated for the associations with LTFU and VF by Cox regression.Among 3604 individuals, the proportions retained in care for one year were 84%, 79%, 72%, and 69% for patients reporting non-use, alcohol use, NIDU, and both alcohol and NIDU, respectively. For the same patient groups, the proportions LTFU over 18 months were 6%, 8%, 12%, and 13%, respectively. There were 1901 patients (53%) with HIV RNA results; VF proportions were similar between users and nonusers (ranging from 14-16%). After controlling for age, sex, study site, HIV transmission mode, time on ART, AIDS status, and CD4 count, neither alcohol use (aOR = 1.1, CI = 0.9-1.4; aHR = 1.0, CI = 0.8-1.3) nor NIDU (aOR = 1.3, CI = 0.9-1.8; aHR = 1.4, CI = 0.9-2.1) were significantly associated with retention or VF, respectively. However, both alcohol use (aHR = 1.2, CI = 1.02-1.4) and NIDU (aHR = 1.3, CI = 1.00-1.8) were associated with increased LTFU.Alcohol use and NIDU in a 7-day recall period increased the risk of being LTFU during the next 18 months, highlighting the need for routine screening and targeted interventions to keep these individuals in care and on ART.

Project description:BACKGROUND:Fungal infections remain a major contributor to the opportunistic infections that affect people living with HIV. Among them, histoplasmosis is considered neglected, often being misdiagnosed as tuberculosis, and is responsible for numerous deaths in Latin America. The objective of this study was to estimate the burden of HIV-associated histoplasmosis compared with tuberculosis in Latin American countries. METHODS:For this modelling study, we estimated prevalence of previous exposure to Histoplasma capsulatum, HIV-associated histoplasmosis annual incidence, and number of deaths in 2012 in Latin American countries based on historical histoplasmin skin test studies in the general population, with an antigen dilution level of more than 1/10. Studies were identified in a literature search. Data on HIV-associated tuberculosis were extracted from the WHO notifications and outcomes tables and data on people living with HIV were extracted from the UNAIDS report for the year 2012. We systematically propagated uncertainty throughout all the steps of the estimation process. FINDINGS:Among 1310 articles identified as of June 1, 2015, 24 articles were included in the study, representing 129 histoplasmin skin test studies led in the general population of Latin American countries. For the year 2012, we estimated a range of 6710 (95% CI 5680-7867) to 15?657 (13?254-18?357) cases of symptomatic HIV-associated histoplasmosis in Latin America. Hotspot areas for histoplasmosis prevalence (>30%) and incidence (>1·5 cases per 100 people living with HIV) were Central America, the northernmost part of South America, and Argentina. According to realistic scenarios, we estimated a range of 671 (95% CI 568-787) to 9394 (7952-11?014) deaths related to histoplasmosis, compared with 5062 (3777-6405) deaths related to tuberculosis reported in Latin America. INTERPRETATION:Our estimates of histoplasmosis incidence and deaths are high and consistent with published data. For the first time, the burden of histoplasmosis is estimated to be equivalent in incidence and even higher in deaths when compared with tuberculosis among people living with HIV in Latin America. FUNDING:None.

Project description:ObjectiveTo examine maternal characteristics associated with adverse pregnancy outcomes among women infected with HIV.DesignProspective cohort study.SettingMultiple sites in Latin America and the Caribbean.PopulationWomen infected with HIV enrolled in the Perinatal (2002-2007) and the Longitudinal Study in Latin American Countries (LILAC; 2008-2012) studies of the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) International Site Development Initiative (NISDI).MethodsFrequencies of adverse pregnancy outcomes assessed among pregnancies. Risk factors investigated by logistic regression analysis.Main outcome measuresAdverse pregnancy outcomes, including preterm delivery (PT), low birthweight (LBW), small for gestational age (SGA), stillbirth (SB), and neonatal death.ResultsAmong 1512 women, 1.9% (95% confidence interval, 95% CI, 1.3-2.7) of singleton pregnancies resulted in a stillbirth and 32.9% (95% CI 30.6-35.4) had at least one adverse pregnancy outcome. Of 1483 singleton live births, 19.8% (95% CI 17.8-21.9) were PT, 14.2% (95% CI 12.5-16.1) were LBW, 12.6% (95% CI 10.9-14.4) were SGA, and 0.4% (95% CI 0.2-0.9) of infants died within 28 days of birth. Multivariable logistic regression modelling indicated that the following risk factors increased the probability of having one or more adverse pregnancy outcomes: lower maternal body mass index at delivery (odds ratio, OR, 2.2; 95% CI 1.4-3.5), hospitalisation during pregnancy (OR 3.3; 95% CI 2.0-5.3), hypertension during pregnancy (OR 2.7; 95% CI 1.5-4.8), antiretroviral use at conception (OR 1.4; 95% CI 1.0-1.9), and tobacco use during pregnancy (OR 1.7; 95% CI 1.3-2.2). The results of fitting multivariable logistic regression models for PT, LBW, SGA, and SB are also reported.ConclusionsWomen infected with HIV had a relatively high occurrence of adverse pregnancy outcomes, and some maternal risk factors were associated with these adverse pregnancy outcomes. Interventions targeting modifiable risk factors should be evaluated further.
