Elucidating the clinical and genetic spectrum of inositol polyphosphate phosphatase INPP4A-related neurodevelopmental disorder.

Purpose: Biallelic INPP4A variants have recently been associated with severe neurodevelopmental disease in single-case reports. Here, we expand and elucidate the clinical-genetic spectrum and provide a pathomechanistic explanation for genotype-phenotype correlations.

Methods: Clinical and genomic investigations of 30 individuals were undertaken alongside molecular and in silico modelling and translation reinitiation studies.

Development and evaluation of a simple treatment eligibility score (HEPSANET) to decentralise hepatitis B care in Africa: a cross-sectional study.

Background: Hepatitis B virus (HBV) elimination requires expanding and decentralising HBV care services. However, peripheral health facilities lack access to diagnostic tools to assess eligibility for antiviral therapy. Through the Hepatitis B in Africa Collaborative Network (HEPSANET), we aimed to develop and evaluate a score using tests generally available at lower-level facilities, to simplify the evaluation of antiviral therapy eligibility in people living with HBV.

Availability of substance use screening and treatment within HIV clinical sites across seven geographic regions within the IeDEA consortium.

Background: Overwhelming evidence highlights the negative impact of substance use on HIV care and treatment outcomes. Yet, the extent to which alcohol use disorder (AUD) and other substance use disorders (SUD) services have been integrated within HIV clinical settings is limited. We describe AUD/SUD screening and treatment availability in HIV clinical sites participating in the International epidemiology Databases to Evaluate AIDS (IeDEA) consortium.

Antiviral Activity of Lenacapavir Against Human Immunodeficiency Virus Type 2 (HIV-2) Isolates and Drug-Resistant HIV-2 Mutants.

The activity of lenacapavir against human immunodeficiency virus type 1 (HIV-1) has been extensively evaluated in vitro, but comparable data for human immunodeficiency virus type 2 (HIV-2) are scarce. We determined the anti-HIV-2 activity of lenacapavir using single-cycle infections of MAGIC-5A cells and multicycle infections of a T-cell line. Lenacapavir exhibited low-nanomolar activity against HIV-2, but was 11- to 14-fold less potent against HIV-2 in comparison to HIV-1.

Thyroid gland is an endocrine gland playing a major role in energy and phosphocalcic metabolism, among others. It commonly occurs in the anterior cervical and pretracheal region. Ectopic thyroid is quite rare.

Informing a target product profile for rapid tests to identify HBV-infected pregnant women with high viral loads: a discrete choice experiment with African healthcare workers.

Background: Elimination of mother-to-child transmission of hepatitis B virus (HBV) requires infant immunoprophylaxis and antiviral prophylaxis for pregnant women with high viral loads. Since real-time polymerase chain reaction (RT-PCR), a gold standard for assessing antiviral eligibility, is neither accessible nor affordable for women living in low-income and middle-income countries (LMICs), rapid diagnostic tests (RDTs) detecting alternative HBV markers may be needed. To inform future development of the target product profile (TPP) for RDTs to identify highly viremic women, we used a discrete choice experiment (DCE) and elicited preference and trade-off of healthcare workers (HCW) in Africa between the following four attributes of fictional RDTs: price, time-to-result, diagnostic sensitivity, and specificity.

Surveillance of Viral Encephalitis in the Context of COVID-19: A One-Year Observational Study among Hospitalized Patients in Dakar, Senegal.

The burden of encephalitis and its associated viral etiology is poorly described in Africa. Moreover, neurological manifestations of COVID-19 are increasingly reported in many countries, but less so in Africa. Our prospective study aimed to characterize the main viral etiologies of patients hospitalized for encephalitis in two hospitals in Dakar.

Spectrum of Activity of Raltegravir and Dolutegravir Against Novel Treatment-Associated Mutations in HIV-2 Integrase: A Phenotypic Analysis Using an Expanded Panel of Site-Directed Mutants.

Background: Integrase inhibitors (INIs) are a key component of antiretroviral therapy for human immunodeficiency virus-1 (HIV-1) and HIV-2 infection. Although INI resistance pathways are well-defined for HIV-1, mutations that emerge in HIV-2 in response to INIs are incompletely characterized.

Methods: We performed systematic searches of GenBank and HIV-2 drug resistance literature to identify treatment-associated mutations for phenotypic evaluation.

Resource and infrastructure challenges on the RESIST-2 Trial: an implementation study of drug resistance genotype-based algorithmic ART switches in HIV-2-infected adults in Senegal.

Background: Second-line treatment of HIV-2 in resource-limited settings (RLS) is complicated by a lack of controlled trial data, limited availability of HIV-2-active antiretroviral drugs, and inadequate access to drug resistance testing. We conducted an implementation trial of a dried blood spot- (DBS) based, drug resistance genotype-informed antiretroviral therapy (ART) switching algorithm for HIV-2-infected patients in Senegal.

Methods: HIV-2-infected adults initiating or receiving ART through the Senegalese national AIDS program were invited to participate in this single-arm trial.

[Features of the incarcerated population followed on an outpatient basis in the Department of Psychiatry of the National University Hospital of Fann in Senegal].

Introduction: psychiatric disorders affect the highest number of incarcerated individuals. Indeed, detention conditions in Senegal have been criticized for several years by referring, in particular, to overcrowding. These conditions probably play a determining role in the occurrence of mental disorders in this population.

Impact of Traditional Healers on the HIV Care Cascade in Senegal, West Africa: A Longitudinal Study.

Consultation with traditional healers (THs) is common among people living with HIV in sub-Saharan Africa. We conducted a prospective longitudinal study to determine the association between consultation with THs and HIV outcomes following 12 months of antiretroviral therapy (ART). HIV-infected individuals presenting for care and initiation of ART in Dakar and Ziguinchor, Senegal were eligible for enrollment.

Chronic viral hepatitis, HIV infection and Non-Hodgkin lymphomas in West Africa, a case-control study.

Non-Hodgkin lymphomas (NHL) are underestimated causes of cancer in West Africa where chronic viral hepatitis and HIV are endemic. While the association with HIV infection has already been characterized, limited information is available on the association between chronic viral hepatitis and NHL in sub-Saharan Africa. A case-control study was conducted in referral hospitals of Abidjan (Cote d'Ivoire) and Dakar (Senegal).

Food insecurity predicts loss to follow-up among people living with HIV in Senegal, West Africa.

The goals of this study were to assess retention on antiretroviral therapy (ART) and to identify predictors of loss to follow-up (LTFU) among people living with HIV (PLHIV) in Senegal. HIV-positive individuals presenting for initiation of ART in Dakar and Ziguinchor were enrolled and followed for 12 months. Data were collected using interviews, clinical evaluations, laboratory analyses, chart review, and active patient tracing.

The impact of food insecurity on HIV outcomes in Senegal, West Africa: a prospective longitudinal study.

Background: Understanding the impact of food insecurity on HIV outcomes is critical for the development and implementation of effective, evidence-based interventions to address food insecurity and improve the HIV care cascade. We conducted a prospective, longitudinal study to determine the impact of food insecurity on HIV outcomes in Senegal, West Africa.

Methods: HIV-infected individuals presenting for care and initiation of ART through the Senegalese National AIDS program in Dakar and Ziguinchor were eligible for enrollment.

[Ensuring continuity of care at the time of COVID-19: challenges for the Dakar Integrated Support Center for Addictions].

The COVID-19 pandemic has an impact on health systems, whose modes of adaptation and response on the ground are still poorly documented and are evolving. The Dakar Integrated Support Center for Addictions (CEPIAD) has been implementing risk reduction since 2014, particularly with drug users. The COVID-19 pandemic and related public health measures were an obstacle to its attendance by patients, in particular due to movement restriction.

Long-term Experience and Outcomes of Programmatic Antiretroviral Therapy for Human Immunodeficiency Virus Type 2 Infection in Senegal, West Africa.

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.
