Background: Programmatic treatment outcome data for people living with human immunodeficiency virus type 2 (HIV-2) in West Africa, where the virus is most prevalent, are scarce.

Methods: Adults with HIV-2 initiating or receiving antiretroviral therapy (ART) through the Senegalese national AIDS program were invited to participate in this prospective, longitudinal observational cohort study. We analyzed HIV-2 viral loads, CD4 cell counts, antiretroviral drug resistance, loss to follow-up, and mortality.

HIV-2 Drug Resistance Genotyping from Dried Blood Spots.

The treatment of HIV-2 in resource-limited settings (RLS) is complicated by the limited availability of HIV-2-active antiretroviral drugs and inadequate access to HIV-2 viral load and drug resistance testing. Dried blood spots (DBS)-based drug resistance testing, widely studied for HIV-1, has not been reported for HIV-2 and could present an opportunity to improve care for HIV-2-infected individuals. We selected 150 DBS specimens from ongoing studies of antiretroviral therapy (ART) for HIV-2 infection in Senegal and subjected them to genotypic drug resistance testing.

An assessment of the core capacities of the Senegalese health system to deliver Universal Health Coverage.

Senegal is firmly committed to the objective of universal health coverage (UHC). Various initiatives have been launched over the past decade to protect the Senegalese population against health hazards, but these initiatives are so far fragmented. UHC cannot be achieved without health system strengthening (HSS).

Oncogenic Properties of the EBV ZEBRA Protein.

Epstein Barr Virus (EBV) is one of the most common human herpesviruses. After primary infection, it can persist in the host throughout their lifetime in a latent form, from which it can reactivate following specific stimuli. EBV reactivation is triggered by transcriptional transactivator proteins ZEBRA (also known as Z, EB-1, Zta or BZLF1) and RTA (also known as BRLF1).

[HIV-2 infection in Senegal: virological failures and resistance to antiretroviral drugs (ARVs)].

Introduction: HIV-2, endemic in West Africa, has a natural resistance to non-nucleoside reverse transcriptase inhibitors (NNRTIs) which makes it difficult to treat it in developing countries.

Methods: We conducted a descriptive, longitudinal, prospective study over the period November 2005-June 2017. Virologic failure has been defined as any viral load greater than 50 copies/ml after 6 months of ARV treatment administered twice.

Ventilation feedback device for manual ventilation in simulated respiratory arrest: a crossover manikin study.

Background: Studies have shown that providing adequate ventilation during CPR is essential. While hypoventilation is often feared by most caregivers on the scene, the most critical problem remains hyperventilation. We developed a Ventilation Feedback Device (VFD) for manual ventilation which monitors ventilatory parameters and provides direct feedback about ventilation quality to the rescuer.

Nutrition support for HIV-TB co-infected adults in Senegal, West Africa: A randomized pilot implementation study.

Background: Food insecurity can contribute to poor adherence to both tuberculosis treatment and HIV antiretroviral therapy (ART). Interventions that target food insecurity have the potential to increase treatment adherence, improve clinical outcomes, and decrease mortality. The goals of this study were to compare the feasibility, acceptability, and potential impact of implementing two different forms of nutrition support for HIV-TB co-infected adults in the Casamance region of Senegal.

Traditional healers, HIV outcomes, and mortality among people living with HIV in Senegal, West Africa.

Background: The WHO guidelines for the management of advanced HIV disease recommend a package of care consisting of rapid initiation of antiretroviral therapy (ART), enhanced screening and diagnosis of tuberculosis (TB) and cryptococcal meningitis, co-trimoxazole prophylaxis, isoniazid preventive therapy (IPT), fluconazole pre-emptive therapy, and adherence support. The goals of this study were to determine the prevalence of advanced HIV disease among individuals initiating ART in Senegal, to identify predictors of advanced disease, and to evaluate adherence to the WHO guidelines.

Methods: This study was conducted among HIV-positive individuals initiating ART in Dakar and Ziguinchor, Senegal.

Severe tricuspid valve destruction secondary to previous non-appropriately treated endocarditis.

Tricuspid valve(TV) destruction with a remote history of endocarditis without known risk factors (ie, HIV, intravenous drug use, neoplasm, trauma) is rare. We describe the case of a TVs destruction in a 12-year-old non-HIV boy, with a 4-year history of endocarditis without known risk factors nor evidence regarding previous appropriately management.

HIV-1 Tat protein induces aberrant activation of AICDA in human B-lymphocytes from peripheral blood.

Individuals infected with human immunodeficiency virus (HIV) are at increased risk for Burkitt lymphoma, a B-cell malignancy which occurs after a chromosomal translocation rearranging the MYC oncogene with an immunoglobulin gene locus, usually the IGH heavy chain gene locus. We have previously reported that the HIV protein Tat which circulates in all HIV-positive individuals whatever their immune status caused an increased rate of colocalization between IGH and MYC in B-cells nuclei. We here present in vitro evidence that Tat activates the expression of the AICDA gene that encodes the activation-induced cytidine deaminase whose physiological function is to create double-strand breaks for immunoglobulin gene maturation.
