Background: Although cutaneous mycoses are a global public health problem, very few data are available in the Democratic Republic of Congo (DRC).

Objectives: This study aimed to describe the retrospective clinical epidemiology of dermatomycosis and their associated risk factors in dermatological consultations in Kinshasa, DRC.

Methods: A retrospective study based on the medical records of patients seen in the departments of dermatology of 2 major hospitals in Kinshasa from March 2000 to August 2023 was carried out.

We evaluated the prevalence of serum and meningeal cryptococcosis in asymptomatic outpatients with advanced HIV disease (CD4 < 200 cells/mm3) in a cross-sectional screening context in Kinshasa clinics (DRC). Lumbar puncture (LP) was performed in patients with positive serum cryptococcal antigen (CrAg) test, and Cryptococcus spp. isolated from cerebrospinal fluid (CSF) were identified by MALDI-TOF-MS, and characterized using serotyping-PCR, ITS-sequencing and multilocus sequence typing (MLST).

The African BioGenome Project (AfricaBP) Open Institute for Genomics and Bioinformatics aims to overcome barriers to capacity building through its distributed African regional workshops and prioritizes the exchange of grassroots knowledge and innovation in biodiversity genomics and bioinformatics. In 2023, we implemented 28 workshops on biodiversity genomics and bioinformatics, covering 11 African countries across the 5 African geographical regions. These regional workshops trained 408 African scientists in hands-on molecular biology, genomics and bioinformatics techniques as well as the ethical, legal and social issues associated with acquiring genetic resources.

Article Synopsis
  • IPTp-SP faces challenges due to rising resistance of Plasmodium falciparum to sulfadoxine-pyrimethamine, but its effects on maternal and newborn health were examined in a study involving 844 laboring women in Kinshasa, DRC.
  • The study found that maternal malaria was present in 10.8% of women at delivery, linked to higher instances of fever and anemia, while a significant mutation profile in the malaria parasites suggested ongoing susceptibility to SP.
  • Although IPTp-SP did not reduce maternal malaria, it showed a protective effect against negative pregnancy outcomes, such as maternal anemia, shortened gestation periods, and low birth weights, particularly with three or more doses administered.

Background: This study aimed to estimate the socio-economic costs of uncomplicated malaria and to explore health care-seeking behaviours that are likely to influence these costs in the Democratic Republic of Congo (DRC), a country ranked worldwide as the second most affected by malaria.

Methods: In 2017, a cross-sectional survey included patients with uncomplicated malaria in 64 healthcare facilities from 10 sentinel sites of the National Malaria Control Programme (NMCP) in the DRC. A standard questionnaire was used to assess health care-seeking behaviours of patients.

Artemisinin-based combination therapies (ACTs) have been recommended by the World Health Organization (WHO) as first-line treatment of uncomplicated Plasmodium falciparum (P. falciparum) malaria since 2005 in Democratic Republic of Congo (DRC) and a regular surveillance of the ACT efficacy is required to ensure the treatment effectiveness. Mutations in the propeller domain of the pfk13 gene were identified as molecular markers of artemisinin resistance (ART-R).

Malaria is a major public health problem in the Democratic Republic of Congo. Despite progress achieved over the past decade in the fight against malaria, further efforts have to be done such as in the surveillance and the containment of Plasmodium falciparum resistant strains. We investigated resistance to artemisinin-based combination therapies currently in use in Democratic Republic of Congo by surveying molecular polymorphisms in three genes: pfcrt, pfmdr1 and pfk13 to explore possible emergence of amodiaquine, lumefantrine or artemisinin resistance in Democratic Republic of Congo.

Plasmodiums are protozoa that may infect various hosts. Only five species are now recognized as naturally parasitizing humans: Plasmodium falciparum, Plasmodium vivax, Plasmodium malariae, Plasmodium ovale and Plasmodium knowlesi. This fifth species, P.

Malaria remains a major public health problem in the Democratic Republic of Congo (DRC) with 14 million cases reported by the WHO Malaria Report in 2014. Asymptomatic malaria cases are known to be prevalent in endemic areas and are generally untreated, resulting in a significant source of gametocytes that may serve as reservoir of disease transmission. Considering that microscopy certainly underestimates the prevalence of Plasmodium infections within asymptomatic carriers and that PCR assays are currently recognized as the most sensitive methods for Plasmodium identification, this study was conducted to weigh the asymptomatic carriage in DRC by a molecular method.
