[Co-infection of malaria and COVID-19 in patients admitted to the COVID Infectious Disease Department of the Libreville University Hospital Center]. / Co-infection paludisme et COVID-19 chez les patients admis au service d'infectiologie COVID du Centre Hospitalier Universitaire de Libreville.

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. For each patient, demographics (age, gender, weight, height), history and clinical and biological examination results were reported in the Excel file. Of a total of 253 patients who met the inclusion criteria, 8 had malaria associated with positive SARS-CoV-2 PCR. These were women (3) and men (5), with an average age of 36.9 years (25- 53 years). The mode of transmission was unknown in 7/8. All patients were febrile, 6/8 had headaches and 5/8 had respiratory discomfort. Less than half of patients had otolaryngeal (anosmia, ageusia) or digestive (diarrhea) manifestations. One patient with severe form died on day 5 of hospitalization. Clinical similarities between malaria and COVID-19 can lead to confusion in malaria endemic areas. The co-infection of malaria and COVID-19 did not result in severe clinical forms.

Profil clinique et évolutif des patients atteints du COVID-19 à Libreville étude rétrospective et mono-centrique / Clinical and evolutionary profile of patients with COVID-19 in Libreville: A Retrospective Cohort study

Introduction : L'étude clinique des patients infectés par le SARS-CoV2 est nécessaire pour la mise en œuvre des mesures préventives de lutte contre la COVID-19. L'objectif de l'étude a été de déterminer le profil clinique et évolutif des patients Covid-19 au CHU de Libreville.Méthodes : Il s'agit d'une étude rétrospective à viser analytique menée en secteur d'infectiologie COVID du SICOV du CHU de Libreville sur une période d'activité allant du 15 mars au 30 juin. La régression logistique univariée et multivariée pour explorer les facteurs de risque associés à la mortalité au SICOV a été utilisée. Résultats : Au total 441 patients COVID-19 étaient inclus dans l'étude, parmi lesquels 398 survivants (90,2%) et 43 décédés (9,8%). La population de moins de 65 ans représentait 88,0% de l'effectif. Le sex-ratio était de 1,34. Par rapport aux 398 survivants, les 43 patients décédés étaient significativement plus âgés (âge médian, 59 ans vs 48 ans ; p <0,001). Les lésions pulmonaires avec atteinte critique > 75% étaient plus importantes chez les patients décédés (29,2% vs 3,0% ; p=0,001). Cependant, après ajustement en analyse multivariée, l'âge supérieur à 65 ans était le seul facteur de risque indépendant de décès (p<0,001 ; OR=4,632 IC95% [2,243 ­ 9,565]).Conclusion : L'âge supérieur à 65 ans était le facteur de risque indépendant de décès, nécessitant un renforcement de mesure de contrôle de l'infection dans cette population

Introduction: The study of the prognostic factors of death of patients infected with SARS-CoV2 is necessary for the implementation of preventive measures against COVID-19. Methods: This is a retrospective study conducted in the COVID infectious disease sector of the SICOV of the University Hospital of Libreville over a period of activity from March 15 to June 30. The clinical course of the survivors and the deceased were compared. Univariate and multivariate logistic regression to explore risk factors associated with SICOV deaths were used.Results: A total of 441 COVID-19 patients were included in the study, of which 398 survivors (90.2%) and 43 died (9.8%). The population under 65 represented 88.0% of the workforce. The sex ratio was 1.34. Compared to the 398 survivors, the 43 patients who died were significantly older (median age, 59 years vs 48 years; p <0.001). Lung lesions with critical impairment > 75% were greater in deceased patients (29.2% vs. 3.0%; p = 0.001). On multivariate analysis, age over 65 was the main independent risk factor for death (p <0.001; OR = 4.632 95% CI [2.243 - 9.565]).Conclusion: Age over 65 was the independent risk factor for death, requiring increased infection control measures in this population
