Feasibility, safety, efficacy and potential scaling-up of sofosbuvir-based HCV treatment in Central and West Africa: (TAC ANRS 12311 trial).

Access to Hepatis C treatment in Sub-Saharan Africa is a clinical, public health and ethical concern. The multi-country open-label trial TAC ANRS 12311 allowed assessing the feasibility, safety, efficacy of a specific care model of HCV treatment and retreatment in patients with hepatitis C in Sub Saharan Africa. Between November 2015 and March 2017, with follow-up until mid 2019, treatment-naïve patients with HCV without decompensated cirrhosis or liver cancer were recruited to receive 12 week-treatment with either sofosbuvir + ribavirin (HCV genotype 2) or sofosbuvir + ledipasvir (genotype 1 or 4) and retreatment with sofosbuvir + velpatasvir + voxilaprevir in case of virological failure.

Metabolic causes of liver disease among adults living with HIV from low- and middle-income countries: a cross-sectional study.

Introduction: Liver disease is a leading cause of morbidity and mortality among persons living with HIV (PLHIV). While chronic viral hepatitis has been extensively studied in low- and middle-income countries (LMICs), there is limited information about the burden of metabolic disorders on liver disease in PLHIV.

Methods: We conducted a cross-sectional analysis of baseline data collected between October 2020 and July 2022 from the IeDEA-Sentinel Research Network, a prospective cohort enrolling PLHIV ≥40 years on antiretroviral treatment (ART) for ≥6 months from eight clinics in Asia, Americas, and central, East, southern and West Africa.

Patient-reported outcomes with direct-acting antiviral treatment for hepatitis C in West and Central Africa (TAC ANRS 12311 trial).

Background & Aims: Patient-reported outcomes (PROs) are poorly documented for patients with chronic hepatitis C on direct-acting antiviral (DAA) treatment in low-to-middle-income countries. We documented PROs during and after DAA treatment in participants of the TAC ANRS 12311 trial (West and Central Africa).

Methods: Trial participants received a 12-week regimen containing either sofosbuvir plus ribavirin (HCV genotype 2, n = 40), or sofosbuvir plus ledipasvir (HCV genotypes 1 and 4, n = 80).

Cost-utility analysis of four WHO-recommended sofosbuvir-based regimens for the treatment of chronic hepatitis C in sub-Saharan Africa.

Background: Although direct-acting antivirals (DAA) have become standard care for patients with chronic hepatitis C worldwide, there is no evidence for their value for money in sub-Saharan Africa. We assessed the cost-effectiveness of four sofosbuvir-based regimens recommended by the World Health Organization (WHO) in Cameroon, Côte d'Ivoire and Senegal.

Methods: Using modelling, we simulated chronic hepatitis C progression with and without treatment in hypothetical cohorts of patients infected with the country's predominant genotypes (1, 2 and 4) and without other viral coinfections, history of liver complication or hepatocellular carcinoma.

The Prognostic Values of Neutrophil-to-lymphocyte Ratio and Platelet-to-Lymphocyte Ratio at Baseline in Predicting the In-hospital Mortality in Black African Patients with Advanced Hepatocellular Carcinoma in Palliative Treatment: A Comparative Cohort Study.

Background: The prognostic values of the neutrophil-to-lymphocyte ratio (NLR) and the platelet-to-lymphocyte ratio (PLR) in predicting the in-hospital mortality of Black African patients with advanced hepatocellular carcinoma (HCC) in palliative treatment is unknown.

Aim: To determine the prognostic value of NLR and PLR compared with that of Child-Turcotte-Pugh (CTP), model for end-stage liver disease (MELD) scores and the Barcelona clinic liver cancer staging system (BCLC).

Methods: The cutoffs, accuracies and association with the mortality of these prognostic scores were determined using a time-dependent area under receiver operating characteristic curves (AUC), the log rank test and Cox proportional hazards ratio.

The Impact of Virologic Parameters and Liver Fibrosis on Health-Related Quality of Life in Black African Patients with Chronic Hepatitis B: Results from a High Endemic Area.

Background: The effects of virologic parameters, liver fibrosis, and treatment on the HRQoL in black African patients with CHB are unknown.

Objective: To determine the magnitude and the effects of hepatitis B e antigen (HBeAg), hepatitis B surface antigenemia (HBs antigenemia), viral load, liver fibrosis and treatment on HRQoL impairment in black African patients with CHB using the SF36 (SF36) and chronic liver disease questionnaires (CLDQ).

Materials And Methods: HRQoL comparison was determined in a case-control study and enrolled 214 patients with CHB (mean age: 42 years, male: 65.

Model-based cost-effectiveness estimates of testing strategies for diagnosing hepatitis C virus infection in Central and Western Africa.

Background: Whereas 72% of hepatitis C virus (HCV)-infected people worldwide live in low- and middle-income countries (LMICs), only 6% of them have been diagnosed. Innovative technologies for HCV diagnosis provide opportunities for developing testing strategies more adapted to resource-constrained settings. However, studies about their economic feasibility in LMICs are lacking.

Long-term clinical benefits of Sofosbuvir-based direct antiviral regimens for patients with chronic hepatitis C in Central and West Africa.

Background: In Sub-Saharan Africa, chronic hepatitis C (CHC) is a major public health issue. We estimated the long-term clinical benefits of treating CHC with sofosbuvir-based regimens in Cameroon, Côte d'Ivoire and Senegal using Markov model combining data from the literature with estimates of direct-acting antiviral (DAAs) effectiveness in West and Central Africa.

Methods: Disease progression was simulated with and without treatment in fictive cohorts of patients "diagnosed" with CHC in Cameroon (n = 3224), Côte d'Ivoire (n = 9748) and Senegal (n = 6358).

Model-based cost-effectiveness estimates of testing strategies for diagnosing hepatitis C virus infection in people who use injecting drugs in Senegal.

Background: Scaling-up the access to hepatitis C virus (HCV) diagnostics for people who use injecting drugs (PWID) is essential to reduce the HCV incidence in low and middle-income countries.

Methods: A decision tree model was developed to compare the cost-effectiveness of 12 strategies for diagnosing HCV in Senegal with a health sector perspective. Strategies included HCV-Ab screening and confirmation of viraemia (based on HCV-RNA or HCV core antigen detection) or only the latter step.

The burden of irritable bowel syndrome and chronic constipation on health-related quality of life in black Africans: a comparison with healthy control subjects in Côte d'Ivoire, West Africa.

Although patients with irritable bowel syndrome (IBS) and chronic constipation (CC) have an impaired health-related quality of life (HRQoL), little is known in black African patients compared with control subjects. This study provided the magnitude and the influencing factors of HRQoL impairment in black African outpatients with IBS or CC compared with control subjects using the generic SF-36 questionnaire. One hundred and four consecutive black African outpatients complaining with IBS (n=72, mean age=38.

Systemic inflammatory response syndrome and model for end-stage liver disease score accurately predict the in-hospital mortality of black African patients with decompensated cirrhosis at initial hospitalization: a retrospective cohort study.

Background: Systemic inflammatory response syndrome (SIRS) and model for end-stage liver disease (MELD) predict short-term mortality in patients with cirrhosis. Prediction of mortality at initial hospitalization is unknown in black African patients with decompensated cirrhosis.

Aim: This study aimed to look at the role of MELD score and SIRS as the predictors of morbidity and mortality at initial hospitalization.

Twenty-Year Evolution of Hepatitis B Virus and Human Immunodeficiency Virus Prevalence and Incidence in Voluntary Blood Donors in Côte d'Ivoire.

Background: Hepatitis B virus (HBV) and human immunodeficiency virus (HIV) share common risk factors. The parallel description of their frequency over time may help capture their similarities and differences.

Methods: Using data from the National Transfusion Center of Abidjan, we estimated the following over a 20-year period: (1) the prevalence of HIV and hepatitis B surface antigen (HBsAg) positivity at first contact; and (2) the incidence of HIV and HBsAg seroconversion in negative first-time blood donors.

[A plea for introduction of hepatitis B vaccination at birth in Côte d'Ivoire].

The Côte d'Ivoire National Immunization Technical Advisory Group 2015 work plan included elaboration of an opinion on inclusion of hepatitis B vaccination at birth in the Expanded Program on Immunization (EPI) in Côte d'Ivoire. A task force was set up to conduct this assessment according to a systematized method. The task force analysed scientific articles on the burden of hepatitis B in Côte d'Ivoire, the burden of mother-child transmission, the impact of hepatitis B vaccination at birth in countries which have adopted this strategy, the efficacy and safety of hepatitis B vaccine in newborns, the cost-effectiveness of hepatitis B vaccination at birth, and the best strategy to introduce hepatitis B vaccination at birth in the EPI.

Evolution of hepatocellular carcinoma epidemiology in Côte d'Ivoire.

Introduction: Hepatocellular carcinoma is a major concern for Public health in West Africa. In Côte d'Ivoire, the bulk of our knowledge stems from studies conducted decades ago. Our aim was, thus, to assess whether the epidemiological features of this tumor changed recently.

Alcohol use, viral hepatitis and liver fibrosis among HIV-positive persons in West Africa: a cross-sectional study.

Introduction: Liver fibrosis is often the first stage of liver disease in people living with HIV (PLWHIV) in industrialized countries. However, little is known about liver fibrosis and its correlates among PLWHIV in sub-Saharan Africa.

Methods: The study was undertaken in three HIV referral clinics in Côte d'Ivoire, Senegal and Togo.

HIV infection, viral hepatitis and liver fibrosis among prison inmates in West Africa.

Background: Prisoners represent a vulnerable population for blood-borne and sexually transmitted infections which can potentially lead to liver fibrosis and ultimately cirrhosis. However, little is known about the prevalence of liver fibrosis and associated risk factors among inmates in sub-Saharan Africa.

Methods: Screening of liver fibrosis was undertaken in a randomly selected sample of male inmates incarcerated in Lome, Togo and in Dakar, Senegal using transient elastography.

A Trial of Early Antiretrovirals and Isoniazid Preventive Therapy in Africa.

Background: In sub-Saharan Africa, the burden of human immunodeficiency virus (HIV)-associated tuberculosis is high. We conducted a trial with a 2-by-2 factorial design to assess the benefits of early antiretroviral therapy (ART), 6-month isoniazid preventive therapy (IPT), or both among HIV-infected adults with high CD4+ cell counts in Ivory Coast.

Methods: We included participants who had HIV type 1 infection and a CD4+ count of less than 800 cells per cubic millimeter and who met no criteria for starting ART according to World Health Organization (WHO) guidelines.

How to optimize hepatitis C virus treatment impact on life years saved in resource-constrained countries.

Unlabelled: In resource-constrained countries where the prevalence of hepatitis C virus (HCV) disease is usually high, it is important to know which population should be treated first in order to increase treatment effectiveness. The aim was to estimate the effectiveness of different HCV treatment eligibility scenarios in three different countries. Using a Markov model, we estimated the number of life-years saved (LYS) with different treatment eligibility scenarios according to fibrosis stage (F1-F4 or F3-4), compared to base case (F2-F4), at a constant treatment rate, of patients between 18 and 60 years of age, at stages F0/F1 to F4, without liver complications or coinfections, chronically infected by HCV, and treated with pegylated interferon (IFN)/ribavirin or more-efficacious therapies (i.

Aims. To determine the usefulness of platelet count (PC), spleen diameter (SD) and platelet count/spleen diameter ratio (PC/SD ratio) for the prediction of oesophageal varices (OV) and large OV in black African patients with cirrhosis in Côte d'Ivoire. Materials and Methods.

Occult HBV infection in untreated HIV-infected adults in Côte d'Ivoire.

Background: In countries with high rates of chronic HBV, the World Health Organization recommends screening all HIV-infected adults for hepatitis B surface antigen (HBsAg) before initiating antiretroviral therapy (ART), and starting HIV-HBV-coinfected patients on regimens containing lamivudine (3TC) or emtricitabine (FTC) plus tenofovir disoproxil fumarate (TDF). Here, we estimated the prevalence of untreated HIV-infected adults with negative serum HBsAg and detectable plasma HBV DNA in Côte d'Ivoire.

Methods: This was a cross-sectional survey.

Reduced levels of T-cell subsets CD4+ and CD8+ in homozygous sickle cell anaemia patients with splenic defects.

T-lymphocyte subsets were studied in two patient groups: (1) 50 patients with homozygous sickle cell anaemia (SCA) (mean age 12 (range 3-32) years old) in good health at the time of the study who showed no infectious complication. (2) 50 patients (mean age 13 (range 4-29) years old) with normal haemoglobin rate. The global response revealed a significant increase in levels of CD3+ (P=0.
