Quantification of Hepatitis B Virus DNA: Validation of a qPCR Approach to detect Pregnant Women at High Risk to Transmit the Virus in Mali.

Introduction: Mother-to-child transmission (MTCT) of hepatitis B virus (HBV) is one of the main causes of chronic hepatitis B in endemic regions such as West Africa. Its prevention constitutes an essential element to eliminate HBV. Without intervention, rates of vertical transmission of HBV vary depending on the level of viral replication.

Risk of transfusion-associated malaria in sub-Saharan Africa: The case of Mali.

Introduction: Malaria is a health threat in sub-Saharan Africa, where Plasmodium is not tested in blood bags. Our objective was to determine the prevalence of plasmodial carriage in blood bags and the associated factors, and the involvement of these bags in the occurrence of malaria in recipients.

Methods: From 1st April to 30th November, 2020, we conducted a prospective cross-sectional study of 348 blood bags stored at 4°C in Bamako.

A multiplexed real-time PCR assay for simultaneous quantification of human immunodeficiency virus and Hepatitis B virus for low-and-middle- income countries.

Due to shared routes of transmission, including sexual contact and vertical transmission, HIV-HBV co-infection is common, particularly in sub-Saharan Africa. Measurement of viral load (VL), for both HIV and HBV, plays a critical role for determining their infectious phase and monitoring response to antiviral therapy. Implementation of viral load testing in clinical settings is a significant challenge in resource-limited countries, notably because of cost and availability issues.

[Ear tuberculosis concomitant with pulmonary localization in an HIV-immunosuppressed patient, in Bamako, Mali].

Introduction/rationale: Tuberculosis remains a major public health issue. It is an opportunistic pathology, very common in HIV-immunocompromised persons, classifying it at the WHO stage 4. Ear tuberculosis remains a rare and under-diagnosed clinical form.

Neuromeningeal Cryptococcosis and Tuberculosis Coinfection in Bamako: A One-Year Case Series.

Cryptococcosis and tuberculosis are life-threatening opportunistic infections that occur in apparently immunocompetent or severely immunocompromised individuals worldwide. As both infections are strongly linked to HIV infection, they may share certain clinical manifestations, and the interaction of their treatments should be considered. However, despite their similarity, concurrent tuberculosis and cryptococcal infections have rarely been reported in West Africa.

Hepatitis B Virus in West African Children: Systematic Review and Meta-Analysis of HIV and Other Factors Associated with Hepatitis B Infection.

While Hepatitis B virus (HBV) and the human immunodeficiency virus (HIV) are endemic in West Africa, the prevalence of HBV/HIV coinfection and their associated risk factors in children remains unclear. In this review, we sought to assess HBsAg seroprevalence among 0- to 16-year-olds with and without HIV in West African countries and the risk factors associated with HBV infection in this population. Research articles between 2000 and 2021 that reported the prevalence of HBV and associated risk factors in children in West Africa were retrieved from the literature using the Africa Journals Online (AJOL), PubMed, Google Scholar, and Web of Science databases as search tools.

[Neuromeningeal cryptococcosis in an HIV-negative patient with pulmonary tuberculosis in the Infectious and tropical diseases department of the University teaching hospital Point G of Bamako, Mali].

Neuromeningeal cryptococcosis and pulmonary tuberculosis are respectively serious mycotic and bacterial infections occurring in a subject regardless of its HIV serological status. We report here a case of neuromeningeal cryptococcosis associated with pulmonary tuberculosis and malnutrition in an HIV-seronegative patient with a CD4 count of 750/mm, to highlight some particularities opposed to certain literatures. This is an 18-year-old patient, housewife, from Bamako, admitted in the Infectious and tropical diseases department of the University teaching hospital Point G of Bamako on March 13, 2022 for fever and impaired consciousness.

IFNγ, TNFα polymorphisms and IFNγ serum levels are associated with the clearance of drug-resistant P. falciparum in Malian children.

Host immunity has been suggested to clear drug-resistant parasites in malaria-endemic settings. However, the immunogenetic mechanisms involved in parasite clearance are poorly understood. Characterizing the host's immunity and genes involved in controlling the parasitic infection can inform the development of blood-stage malaria vaccines.

The estimated burden of fungal diseases in Mali.

Mali is a developing country facing several health challenges with a high rate of tuberculosis (TB) and a moderate HIV infection burden. Little is known or done about fungal diseases, yet they represent a significant public health problem in certain populations. The aim of this study was to estimate the national burden of fungal disease, and summarize data, diagnostic and treatment gaps.

Point-of-care ultrasound for tuberculosis management in Sub-Saharan Africa-a balanced SWOT analysis.

Point-of-care ultrasound (POCUS) is an increasingly accessible skill, allowing for the decentralization of its use to nonspecialist healthcare workers to guide routine clinical decision-making. The advent of ultrasound-on-a-chip has transformed the technology into a portable mobile health device. Because of its high sensitivity to detect small consolidations, pleural effusions, and subpleural nodules, POCUS has recently been proposed as a sputum-free likely triage tool for tuberculosis (TB).

Raoultella planticola and urinary tract infection: The first laboratory-confirmed case in an HIV-infected patient in Mali.

Raoultella planticola is a Gram-negative, aerobic, non-motile bacterium, abundant in the environment, but rarely associated with pathology in humans. Notably, few urinary tract infections caused by R. planticola have been reported.

Incidence and Predictors of Imported Cases of COVID-19 in Burkina Faso.

Background: To limit the spread of COVID-19 due to imported cases, Burkina Faso has set up quarantine measures for arriving passengers. We aimed to determine the incidence and predictors of imported cases of COVID-19 in Burkina Faso.

Methods: A prospective cohort study was performed using data from passengers arriving at the airport from April 9 to August 31, 2020.

High SARS-CoV-2 Seroprevalence among Healthcare Workers in Bamako, Mali.

In Mali, a country in West Africa, cumulative confirmed COVID-19 cases and deaths among healthcare workers (HCWs) remain enigmatically low, despite a series of waves, circulation of SARS-CoV-2 variants, the country's weak healthcare system, and a general lack of adherence to public health mitigation measures. The goal of the study was to determine whether exposure is important by assessing the seroprevalence of anti-SARS-CoV-2 IgG antibodies in HCWs. The study was conducted between November 2020 and June 2021.

[Cerebral toxoplasmosis in the infectious diseases department of the CHU du Point G in people living with HIV].
