[Socio-demographic and economic profile of adult patients with sickle cell disease followed up on a regular basis at the University Hospital Center of Libreville].

Sickle cell disease is a genetic disease transmitted as an autosomal recessive trait. Since September 2016, at the University Hospital Center of Libreville (UHCL) hematology consultation dedicated to adult patients with sickle cell disease was offered. This was the occasion to conduct this study, the purpose of which was to describe the socio-demographic and economic profile of patients followed up on a regular basis.

[Co-infection of malaria and COVID-19 in patients admitted to the COVID Infectious Disease Department of the Libreville University Hospital Center].

The purpose of this study was to report the cases of co-infection of malaria and COVID-19, after systematic search for plasmodium in patients treated in the COVID Infectious Disease Department (SiCOV) of the Libreville University Hospital (LUH). We conducted a prospective, observational study in the LUH SiCOV from April to July 2020. Patients of both sexes, aged over 18 years, with positive Polymerase Chain Reaction (PCR) test for SARS-CoV-2 with thick blood smear result available, were included.

Complete Blood Count Parameters, C-Reactive Protein and the Severity of Coronavirus Disease.

Background: Coronavirus disease, which initially appeared in Wuhan, China during the month of December 2019, very quickly spread and became a worldwide pandemic. The African continent was not spared. The poor health system and low socioeconomic status in some regions has raised concern on the risk of an epidemic disaster due to the rapid transmission of the virus.

Myeloblasts and atypical bone marrow: Fortuitous discovery of the filiarial nematode loa loa in the bone marrow during a work-up for prolymphocytic T-cell leukemia.

Loiasis is a chronic cutaneous disease caused by a filarial nematode for whom humans are the only definitive host: Loa loa, an African eyeworm transmitted by Chrysops flies. The parasite is seen on blood smears, in the skin, or during its ocular migration, but rarely on a bone marrow smear. We report the case of a 57-year-old Gabonese woman whose bone marrow aspiration during a work-up for T-cell leukemia fortuitously found Loa loa filariae.

The risk of transfusion-transmitted viral infections at the Gabonese National Blood Transfusion Centre.

Background: Blood transfusions carry the risk of transmitting blood-borne infections. In contrast to the situation in the developed world, there is a limited number of studies examining this problem in sub-Saharan Africa. In this study we aimed to calculate the risks of acquiring human immunodeficiency virus (HIV), hepatitis B virus (HBV), and hepatitis C virus (HCV) infection from units of blood issued by the Gabonese Blood Transfusion Centre between 2009 and 2011.
