Molecular epidemiology of non-falciparum Plasmodium infections in three different areas of the Ivory Coast.

Background: Malaria is a major public health problem, particularly in the tropical regions of America, Africa and Asia. Plasmodium falciparum is not only the most widespread but also the most deadly species. The share of Plasmodium infections caused by the other species (Plasmodium ovale and Plasmodium malariae) is clearly underestimated.

Dermatophytosis and the associated risk factors among primary school children in southern and central Côte d'Ivoire.

Background: Dermatophytosis, particularly the subtype tinea capitis, is common among African children; however, the risk factors associated with this condition are poorly understood.

Objectives: This study aimed to determine the factors associated with tinea capitis and the prevalence rate of other dermatophytoses among primary school students in the rural and urban areas of the southern and central Côte d'Ivoire.

Patients And Methods: The study was carried out in seven towns of Côte d'Ivoire from October 2008 to July 2009, among 17,745 children aged 4-17 years and attending urban and rural primary schools; a complete physical examination of the skin and appendages, including nails and hair, was performed by the physicians.

Genotyping Canadian Isolates to Supplement Cyclosporiasis Outbreak Investigations.

is an emerging foodborne parasite that causes cyclosporiasis, an enteric disease of humans. Domestically acquired outbreaks have been reported in Canada every spring or summer since 2013. To date, investigations into the potential sources of infection have relied solely on epidemiological data.

Higher risk of mortality in HIV-HBV co-infected patients from sub-Saharan Africa is observed at lower CD4 cell counts.

Background: Hepatitis B virus (HBV) co-infection in human immunodeficiency virus (HIV)-positive individuals increases the risk of overall mortality, especially when HBV DNA levels are high. The role of CD4 cell counts in this association is poorly defined. We aimed to determine whether HIV-HBV co-infection influences changes in CD4 cell count before and during antiretroviral therapy and whether it affects mortality risk at levels of CD4.

Mortality in relation to hepatitis B virus (HBV) infection status among HIV-HBV co-infected patients in sub-Saharan Africa after immediate initiation of antiretroviral therapy.

It is unknown how past and active hepatitis B virus (HBV) infection affect immunorecovery and mortality in people with HIV who initiate tenofovir-based antiretroviral therapy (ART). Using data collected between 2008 and 2015, we studied people with HIV in sub-Saharan Africa initiating immediate ART in the Temprano randomized control trial. We classified participants into HBV groups at ART initiation: hepatitis B surface antigen (HBsAg)-positive with HBV DNA ≥ 2,000 IU/ml; HBsAg-positive with HBV DNA < 2,000 IU/ml; isolated HBcAb-positive; resolved infection (HBsAb-positive/HBcAb-positive); and HBV non-immune/vaccinated (HBcAb-negative).

Association between cellular HIV-1 DNA level and mortality in HIV-1 infected African adults starting ART with high CD4 counts.

Background: High HIV-1 DNA levels in peripheral blood mononuclear cells (PBMC) were associated with a higher risk of severe morbidity and a faster decline in CD4 count in ART-naive patients. We report the association between HIV-1 DNA and mortality in HIV-infected adults in a trial of early ART in West Africa.

Methods: In the Temprano trial, HIV-infected adults were randomly assigned to start ART immediately or defer ART.

Comparative typing analyses of clinical and environmental strains of the Cryptococcus neoformans/Cryptococcus gattii species complex from Ivory Coast.

Purpose: The aim of this study was to assess the biotope of the Cryptococcus neoformans/Cryptococcus gattii species complex from Ivory Coast, and clarify the possible epidemiological relationship between environmental and clinical strains.

Methodology: Samples from Eucalyptus camaldulensis (n=136), Mangifera indica (n=13) and pigeon droppings (n=518) were collected from different sites close to the living environment of Ivorian HIV patients with cryptococcosis (n=10, 50 clinical strains). Clinical and environmental strains were characterized by molecular serotyping and genotyping [RFLP analysis of the URA5 gene, (GACA)4, (GTG)5 and M13 PCR fingerprinting] and compared.

Effect of isoniazid preventive therapy on risk of death in west African, HIV-infected adults with high CD4 cell counts: long-term follow-up of the Temprano ANRS 12136 trial.

Background: Temprano ANRS 12136 was a factorial 2 × 2 trial that assessed the benefits of early antiretroviral therapy (ART; ie, in patients who had not reached the CD4 cell count threshold used to recommend starting ART, as per the WHO guidelines that were the standard during the study period) and 6-month isoniazid preventive therapy (IPT) in HIV-infected adults in Côte d'Ivoire. Early ART and IPT were shown to independently reduce the risk of severe morbidity at 30 months. Here, we present the efficacy of IPT in reducing mortality from the long-term follow-up of Temprano.
