Profiles of Sexual Economic Exchanges among Women in Kisumu, Kenya: A Latent Class Analysis.

Sexual economic exchanges, including sex work and transactional sex, have been consistently associated with HIV acquisition among young women in sub-Saharan Africa. Heterogeneity in HIV vulnerability across overlapping types of sexual economic exchange has not been sufficiently explored, limiting appropriate and effective linkage to prevention interventions. From January 2017 to May 2018, cross-sectional data were captured at screening for entry into an HIV incidence cohort in Kisumu, Kenya.

HIV incidence and its associated factors among young adults with multiple sexual partners in Maputo, Mozambique: a vaccine preparedness study.

Introduction: Sub-Saharan Africa has a high burden of HIV, particularly among female sex workers (FSW) and men who have sex with men (MSM). Future clinical trials to evaluate vaccines and other interventions to prevent HIV will need to enroll populations with high HIV incidence. We conducted an observational study of HIV incidence among men and women with multiple sexual partners-including MSM and FSW-in Maputo, Mozambique, in order to prepare the country to conduct future efficacy trials of candidate HIV vaccines and other HIV prevention products.

Persistent low-level viraemia is associated with non-infectious comorbidities in an observational cohort in four African countries.

Introduction: People living with HIV (PLWH) have higher rates of non-infectious comorbid diseases (NCDs) than individuals without HIV. We characterized the risk of NCDs among PLWH with undetectable viral load and persistent low-level viraemia (pLLV) in the African Cohort Study (AFRICOS). We secondarily quantified the role of immune activation in the association between LLV and NCDs.

Safety and Immunogenicity of Accelerated Heterologous 2-Dose Ebola Vaccine Regimens in Adults With and Without HIV in Africa.

Background: Shorter prophylactic vaccine schedules may offer more rapid protection against Ebola in resource-limited settings.

Methods: This randomized, observer-blind, placebo-controlled, phase 2 trial conducted in 5 sub-Saharan African countries included people without human immunodeficiency virus (HIV) (PWOH, n = 249) and people with HIV (PWH, n = 250). Adult participants received 1 of 2 accelerated Ebola vaccine regimens (MVA-BN-Filo, Ad26.

Cumulative exposure to depressive symptoms and all-cause mortality among adults with HIV in Kenya, Nigeria, Tanzania, and Uganda.

Objective: We estimated the effects of cumulative exposure to depressive symptoms on risk of all-cause mortality among people with HIV (PWH) in four African countries.

Design: An analysis of prospective cohort data.

Methods: The African Cohort Study (AFRICOS) is a prospective cohort of people receiving care at twelve clinics in Kenya, Nigeria, Tanzania, and Uganda.
