Manifestations cliniques de l'infection à Coronavirus SARS-Cov-2 (COVID-19)

La pandémie causée par le nouveau virus du coronavirus (SARS-CoV-2) à Wuhan, en Chine, en décembre 2019 est une maladie très contagieuse. L'Organisation mondiale de la Santé (OMS) a déclaré que l'épidémie en cours était une urgence mondiale de santé publique. Actuellement, les recherches sur ce nouveau coronavirus sont en cours et plusieurs publications sont disponibles. Les manifestations cliniques liées à l'infection au nouveau Corona-virus SARSCOV-2 semblent être très polymorphes et multi systémiques, dépassant largement le cadre nosologique typiquement respiratoire. Ces manifestations peuvent être cardiovasculaires, dermatologiques, ORL, hépatiques, rénales, ophtalmologiques et même neurologiques. Cette revue décrit les manifestations cliniques ainsi que de la pathogénie connues à ce jour du coronavirus 2019 (COVID19) ; le diagnostic et le traitement ne seront volontairement pas abordés

Admission hyperglycemia and associated risk factors among patients with acute stroke in intensive care units in Kinshasa, the Democratic Republic of the Congo

Context and objective. Despite being established as a correlate of unfavorable outcome in acute stroke, little is known about the burden and associated risk factors of admission hyperglycemia in acute stroke in sub-Saharan Africa. The present study aimed to assess its frequency and associated risk factors in Congolese patients admitted in Intensive Care Units (ICUs) in the acute phase of stroke. Methods. A multicenter (6 ICUs) prospective cohort study including consecutive patients with acute stroke was undertaken from July 15th, 2017 to March 15th, 2018.The Glasgow Coma Scale helped to determine the severety of the disease at admission. Stress hyperglycemia was considered for a random blood glucose levels at admission ˃140 mg/dL in patients without type 2 diabetes mellitus (T2DM). Independent factors associated with admission hyperglycemia were assessed using logistic regression analysis. Results. Out of 194 patients (mean age 58.7±13.1 years; 64% males, 74.7% light to moderate stroke severity; 59% hemorrhagic stroke) enrolled, admission hyperglycemia was found in 106 (54.6%) of patients (mean age 60.1 ± 14.3 years; 67% men, 67% hypertension) with 77 (72.6%) and 29 (27.4 %) of them having stress and chronic hyperglycemia, respectively. Independent predictors of admission hyperglycemia were age [aOR 1.98; 95%CI 1.17-3.36), GCS < 8 (aOR 3.83; 95% CI 1.99-7.35) and diabetes (aOR 9.02; 95%CI 3.38-14.05). Conclusion. More than half of critically ill patients exhibit admission hyperglycemia with age, severity of stroke and known diabetes as its main associated risk factors
