Atorvastatin and telmisartan do not reduce nasopharyngeal carriage of SARS-CoV-2 in mild or moderate COVID-19 in a phase IIb randomized controlled trial.

Observational studies suggest a reduction in fatal or severe COVID-19 disease with the use of ACE2 inhibitors and statins. We implemented a randomized controlled tree-arm open label trial evaluating the benefits of adding telmisartan (TLM) or atorvastatin (ATV) to lopinavir boosted ritonavir (LPVr) on the SARS-CoV-2 nasopharyngeal viral load in patients with mild / moderate COVID-19 infection in Côte d'Ivoire. RT-PCR positive COVID-19 patients ≥ 18 years, with general or respiratory symptoms for less than 7 days were randomized (1:1:1) to receive LPVr (400 mg/100 mg twice daily), LPVr + TLM (10 mg once daily) or LPVr + ATV (20 mg once daily) for 10 days.

Phylogenetic Profile of Nonulcerans and Nontuberculous Environmental Mycobacteria Isolated in Côte d'Ivoire.

Background: Environmental mycobacteria are involved in several infections ranging from lung to skin infections. In Côte d'Ivoire, apart from Mycobacterium ulcerans and Mycobacterium tuberculosis, little information exists on other species. The culture of these species, a real challenge, especially in developing countries like Cote d'Ivoire, limits their identification.

Seroprevalence of SARS-CoV-2 antibodies and retrospective mortality in two African settings: Lubumbashi, Democratic Republic of the Congo and Abidjan, Côte d'Ivoire.

Although seroprevalence studies have demonstrated the wide circulation of SARS-COV-2 in African countries, the impact on population health in these settings is still poorly understood. Using representative samples of the general population, we evaluated retrospective mortality and seroprevalence of anti-SARS-CoV-2 antibodies in Lubumbashi and Abidjan. The studies included retrospective mortality surveys and nested anti-SARS-CoV-2 antibody prevalence surveys.

Mosquito (Diptera: Culicidae) Larval Ecology in Rubber Plantations and Rural Villages in Dabou (Côte d'Ivoire).

In Côte d'Ivoire, rubber cultivation has more than doubled since 2010. These mass agricultural areas require a large workforce with little information on how this environment might impact risk of mosquito-borne diseases. The objective of this study was to assess the larval ecology of mosquitoes in rubber areas of Dabou, Côte d'Ivoire.

Impacts of nutrient loading and fish grazing on the phytoplankton community and cyanotoxin production in a shallow tropical lake: Results from mesocosm experiments.

Given the increasing eutrophication of water bodies in Africa due to increasing anthropogenic pressures, data are needed to better understand the responses of phytoplankton communities to these changes in tropical lakes. These ecosystems are used by local human populations for multiple purposes, including fish and drinking water production, potentially exposing these populations to health threats if, for example, an increase in toxic cyanobacterial blooms is associated with increasing eutrophication. To test the short-term response of the phytoplankton community to the addition of nutrients (phosphorus and nitrogen, alone or in combination) and Nile tilapia, we developed an in situ mesocosm experiment in a freshwater lagoon located near Abidjan (Ivory Coast).

Team experience of nasopharyngeal samples reception, decontamination, and sorting during the COVID-19 pandemic (2020) at Institut Pasteur Côte d'Ivoire.

Molecular testing sensitivity, which allows for early diagnosis of the 2019 coronavirus disease (COVID-19), could be affected by sample quality, storage, and transportation timeframe to the laboratory, along with bias related to the pre-analytic phase. The present study reports the selection and decontamination of nasopharyngeal samples during COVID-19 management at the Institut Pasteur Côte d'Ivoire. The objective of this work was to organize sample reception management and report a complete picture of sample selection and decontamination in the context of diagnosis activity decentralization.

Viral and bacterial factors of mother-to-child transmission of hepatitis B virus.

Hepatitis B virus (HBV) infection is the tenth leading cause of death worldwide. Mother-to-child transmission of HBV occurring mainly at delivery remains one of the most common routes of infection in developing countries. One of the main challenges concerning HBV in Africa is to implement a prevention policy aiming at interrupting the cycle of pseudo-vertical transmission of this infection.
