Investigating linkage to care following community-based screening for hepatitis B virus in rural Senegal: A mixed methods study.

This paper investigates linkage to care following community-based screening for hepatitis B virus (HBV) in rural Senegal. HBV-positive participants who completed a biological and clinical examination to assess liver disease and treatment eligibility were referred to a regional hospital (if eligible for treatment), invited to join the Sen-B research cohort study (adults with detectable viral load) or referred to their local health centre (all others). Logistic regressions were conducted to investigate factors associated with (i) uptake of the scheduled post-screening examination, and (ii) HBV management initiation.

Hepatitis B prevention and treatment needs in women in Senegal (ANRS 12356 AmBASS survey).

Background: Although mother-to-child transmission (MTCT) of hepatitis B virus (HBV) is prevalent in West Africa, epidemiological data on HBV infection in women remain scarce. We studied i) hepatitis B surface antigen (HBsAg) prevalence and its correlates, ii) HBV screening history and serological status awareness, iii) MTCT risk and treatment needs in Senegalese women.

Methods: A cross-sectional population-based serosurvey for HBsAg positivity was conducted in 2018-2019 in the rural area of Niakhar (Fatick region, Senegal).

[Intestinal tuberculosis revealed by acute bowel obstruction during paradoxical reaction to antituberculosis treatment in an immunocompetent patient: about a case and literature review].

Abdominal tuberculosis accounts for 3 to 5% of all visceral diseases. Despite the demonstrated effectiveness of anti-tuberculosis treatments, some cases of exacerbation of the initial clinical presentation have been described during the initiation of treatment. However, these reactions also known as "paradoxical" have been rarely reported in immunocompetent patients and much less in the case of bowel obstruction.

TDF and quantitative ultrasound bone quality in African patients on second line ART, ANRS 12169 2LADY sub-study.

Background: Bone demineralization, which leads to osteoporosis and increased fracture risk, is a common metabolic disorder in HIV-infected individuals. In this study, we aimed to assess the change in bone quality using quantitative ultrasound (QUS) over 96 weeks of follow-up after initiation of second-line treatment, and to identify factors associated with change in bone quality.

Methods And Findings: In a randomized trial (ANRS 12169), TDF and PI-naïve participants failing standard first-line treatment, from Burkina Faso, Cameroon, and Senegal were randomized to receive either TDF/FTC/LPVr, ABC/ddI/LPVr or TDF/FTC/DRVr.

[Prevalence of hepatitis B surface antigen and its associated factors in Senegalese military personnel sent on mission to Darfur].

Introduction: In Senegal, 85% of the adult population have been exposed to the hepatitis B virus and about 11% of them are chronic surface antigen (HBsAg) carriers. This infection is poorly documented among Senegalese Armed Forces. The aim of this study was to assess the prevalence of HBsAg in Senegalese military personnel on mission to Darfur (Sudan) and to identify its associated factors.

Evolution of renal function in African patients initiating second-line antiretroviral treatment: findings from the ANRS 12169 2LADY trial.

Background: To investigate change in renal function in African patients initiating second-line antiretroviral therapy (ART) including ritonavir-boosted protease inhibitor (PI/r) with or without tenofovir disoproxil fumarate (TDF).

Methods: HIV-1-positive adults, failing standard first-line ART were randomized to either TDF/emtricitabine (FTC)+LPV/r, abacavir + didanosine +LPV/r or TDF/FTC+ darunavir (DRV)/r and followed for 18 months. Patients with an estimated glomerular filtration rate (eGFR) ≥60 ml/min/1.

Nutritional status of HIV-infected patients during the first year HAART in two West African cohorts.

Objective: To examine the association between nutritional markers at initiation and during follow up in two different cohorts of HIV-infected adults initiating highly active antiretroviral therapy (HAART) in West Africa.

Methods: The ATARAO study was a one year prospective study carried in Mali. It consisted of a sample of consecutive patients initiating HAART in one of four participating centers during that period.

Development of a checklist of quality indicators for clinical trials in resource-limited countries: the French National Agency for Research on AIDS and Viral Hepatitis (ANRS) experience.

Background: Since 1994, the French National Agency for Research on AIDS and Viral Hepatitis (ANRS) has funded research sites in resource-limited countries (RLCs). These sites implement research on human immunodeficiency virus (HIV) infection and Hepatitis C. In parallel, international regulations and recommendations for clinical trials have evolved and proliferated.

Risk of virological failure and drug resistance during first and second-line antiretroviral therapy in a 10-year cohort in Senegal: results from the ANRS 1215 cohort.

Background: In 1998, Senegal launched one of Africa's first antiretroviral therapy (ART) programs. Since then, the number of treated patients in Africa has substantially increased thanks to simplification in treatment management. Although good outcomes over the first years of ART have been observed in sub-Saharan Africa, little is known about the long-term (>5 years) risks of virological failure and drug resistance and about second-line treatment response.

Reduced quantitative ultrasound bone mineral density in HIV-infected patients on antiretroviral therapy in Senegal.

Background: Bone status in HIV-infected patients on antiretroviral treatment (ART) is poorly documented in resource-limited settings. We compared bone mineral density between HIV-infected patients and control subjects from Dakar, Senegal.

Methods: A total of 207 (134 women and 73 men) HIV-infected patients from an observational cohort in Dakar (ANRS 1215) and 207 age- and sex-matched controls from the general population were enrolled.

Diabetes and Hypertension among Patients Receiving Antiretroviral Treatment Since 1998 in Senegal: Prevalence and Associated Factors.

Cardiovascular risk factors in people on antiretroviral treatment (ART) are poorly documented in resource-constrained settings. A cross-sectional study was conducted in 2009 to assess prevalence of diabetes and hypertension in a sample of 242 HIV-infected patients who had initiated ART between 1998 and 2002 in Dakar, Senegal (ANRS 1215 observational cohort). World Health Organization (WHO) criteria were applied to diagnose diabetes and hypertension.

The development of PROQOL-HIV: an international instrument to assess the health-related quality of life of persons living with HIV/AIDS.

Objectives: Health-related quality of life (HRQL) is an important outcome in HIV/AIDS infection and treatment. However, most existing HIV-HRQL instruments miss important issues (eg, sleeping problems, lipodystrophy). They were developed before highly active antiretroviral therapy (pre-HAART), and in a single language.

Long-term effectiveness and safety of didanosine combined with lamivudine and efavirenz or nevirapine in antiretroviral-naive patients: a 9-year cohort study in Senegal.

Objective: The use of didanosine (ddI) in first-line antiretroviral therapy has been recently promoted for resource-limited settings. We therefore compared the long-term effectiveness and safety of the regimen combining ddI, lamivudine, and efavirenz or nevirapine with that of the WHO-recommended regimen of zidovudine (ZDV), lamivudine, and efavirenz or nevirapine in antiretroviral-naïve patients in Senegal.

Methods: Observational cohort study of patients enrolled between January 2000 and April 2002 in the Senegalese antiretroviral drug access initiative.

Changes in the renal function after tenofovir-containing antiretroviral therapy initiation in a Senegalese cohort (ANRS 1215).

To describe and compare the changes in renal function between HIV-1 infected adult patients receiving antiretroviral therapy (ART) with and without tenofovir (TDF). The population consisted of 40 patients starting a TDF-containing regimen and 388 patients starting regimen not containing TDF, and followed during 42 months. The estimated glomerular filtration rate (eGFR) was calculated using the Cockroft-Gault and MDRD equations and modeled separately for the first 12 months and the subsequent period.

Incidence and determinants of new AIDS-defining illnesses after HAART initiation in a Senegalese cohort.

Background: Although a dramatic decrease in AIDS progression has been observed after Highly Active Anti Retroviral Therapy (HAART) in both low- and high-resource settings, few data support that fact in low-resource settings.This study describes the incidence of AIDS-defining illnesses (ADI) after HAART initiation and analyzes their risk factors in a low-resource setting. A focus was put on CD4 cell counts and viral load measurements.

Short and Long-Term Incidence of Tuberculosis and CD4-Cell Count Dynamic on HAART in Senegal.

Objectives: Estimate tuberculosis (TB) incidence among patients receiving HAART. Compare the dynamic of the CD4-cell count and viral load before notification of the TB with the dynamic among patients remaining free of TB.

Design: Prospective cohort with ascertainment of TB cases from medical records.

Modeling CD4+ cell count increase over a six-year period in HIV-1-infected patients on highly active antiretroviral therapy in Senegal.

To assess the extents and determinants of long-term CD4 cell increases after initiation of antiretroviral therapy (ART), changes in CD4 cell counts were analyzed in a cohort of HIV-1-infected Senegalese using a mixed-effects model. After a median follow-up of 54 months, an average of 483 CD4 cells/mm3 (95% confidence interval [CI] = 331; 680) was reached. The average asymptote level was approximately 421 cells/mm3 (95% CI = 390; 454) in patients with < 200 cells/mm3 at baseline and approximately 500 cells/mm3 in patients with > 200 cells/mm3.

Change over time of mortality predictors after HAART initiation in a Senegalese cohort.

Background: In 1998, Senegal was among the first sub-Saharan African countries to launch a Highly active anti-retroviral therapy (HAART) access program. Initial studies have demonstrated the feasibility and efficacy of this initiative. Analyses showed a peak of mortality short after starting HAART warranting an investigation of early and late mortality predictors.

Mortality and causes of death in adults receiving highly active antiretroviral therapy in Senegal: a 7-year cohort study.

Objectives: To evaluate survival and investigate causes of death among HIV-1 infected adults receiving HAART in Senegal.

Design: An observational prospective cohort.

Methods: Mortality was assessed in the first patients enrolled between August 1998 and April 2002 in the Senegalese antiretroviral drug access initiative.
