RESUMO

Context and objective In intensive care units (ICU), clinicians have little information to identify COVID-19 patients at high risk of poor prognosis requiring intubation. Considering the clinical and biological parameters of the patients during their admission to ICU, we determined the incidence of a pejorative evolution requiring intubation, and secondarily we searched among the starting parameters, which were predictors of the intubation during follow-up Methods We conducted a monocentric retrospective cohort study of adult patients admitted for moderate, severe or critical COVID-19/WHO clinical classification, during the first two waves of the pandemic in Kinshasa/DR Congo. Our primary end point was the incidence of intubation. Potential predictors of intubation were determined by the Cox regression analysis. The relative risk of death was assessed according to treatment with mechanical ventilation. (intubation) Results We included 219 patients (average age of 56.8 ±15.2 years; 75 % men), respectively 37 % in the 1st and 63 % in the 2nd wave of the pandemic.Cumulative incidence of intubation was 24% (1stwave: 26% vs 2nd wave: 24%). One-third of intubations were performed on the first 3 days versus two-thirds beyond the third day. The Cox's regression model showed that among data from the 1st day of ICU admission, those predicting intubation were: age (Hazard ratio: 1.025, CI 95%: 1.005-1.044), obesity (HR: 4.808; CI 95%: 2.660-8.696), corticosteroid therapy (HR: 0.313, CI 95%: 0.102-0.965), ROX index < 4.88 (HR: 2.024, CI 95 %: 1.003-4.080) and black race (HR: 0.502, CI 95%: 0.272-0.928). In total, 54 deaths (25 % of patients) were recorded with a higher relative risk (18.8) in intubated patients. Conclusion A quarter of COVID-19 patients admitted to ICU could worsen and be intubated. The majority of intubations were performed after the third day of admission and mortality was high. The predictors of intubation that have been identified can help anticipate management by being proactive

RESUMO

Context and objective. The steady increase in the number of chronic hemodialysis patients in sub-Saharan Africa (SSA) calls for improved management of those patients. The present study aimed to determine the frequency of hepatitis C virus (HCV) infection, the prevalent genotypes, and the risk factors associated with HCV in hemodialysis patients in Kinshasa (DR Congo). Methods. A cross-sectional study was conducted from February to June 2018 in all hemodialysis centers in Kinshasa. Blood samples were collected from 127 chronic hemodialysis patients and tested for the presence of antibodies against HCV. The HCV genotype was identified by real-time polymerase chain reaction (RT- PCR). Results. Twenty-two (17.3 %) patients were positive for anti-HCV antibodies, ranging from 0 % to 52.9 % in different centers. Genotype 4 was detected in 18/22 (81.8 %), followed by genotype 2 in 2/22 (9.1%), and both genotypes 2 and 4 in one patient (4.5%). One patient had an undetermined genotype (4.5 %). Having received at least 4 transfusions [7,21 (1,09- 10,61); p=0.040)], not being under EPO treatment [5,81(1,47-12,96); p=0.012)], being on hemodialysis for at least 14 months [3,63(1,60-5,05); p=0.035)]and being dialyzed in an overloaded center [2,06(0,83-5,86); p=0.073)] were associated with a greater risk of HCV infection. Conclusion. This high HCV prevalence (17.3 %) represents a substantial health burden in HD patients from Kinshasa, DR Congo. It is largely driven by the number of blood transfusions, the duration time in hemodialysis. Observations from the present study underscore the need of reducing the number of blood transfusions in people on dialysis through the administration of erythropoietin, given the unaffordable cost of HCV therapy for most individuals in DR Congo.


Contexte et Objectifs. Le nombre des patients hémodialisés en Afrique subsaharienne en constante augmentation ; justifiant de ce fait une meilleure prise en charge de ces patients. La présente étude détermine la prévalence de l'infection par le virus de l'hépatite C en en determinant les génotypes ainsi que les facteurs y associés dans ce groupe de patients. Méthodes. 127 patients hémodialisés chroniques ont subis des tests sérologiques à la recherche des anticorps anti-VHC dans plusieurs centres de Kinshasa de février à juin 2018. Le génotype viral a été déterminé par la RT-PCR. Résultats. La fréquence des anticorps anti-VHC a varié de 0 à 52,9 % dans ce groupe. Les génotypes le plus fréquents ont été le 4 (18/22) et le 2 (2/22) ; étant sumultanément rétrouvé chez un patient, et indéterminé chez un autre sujet. Avoir reçu au moins 4 transfusions [7,21 (1,09-10,61; p=0.040)], ne pas être sous EPO [5,81(1,47-12,96); p=0.012)], être en hémodialyse depuis au moins 14 mois [3,63(1,60- 5,05); p=0.035)] et être dialysé dans un centre surchargé [2,06 (0,83-5,86); p=0.073)] étaient associés à un risque plus élevé d'infection par le VHC. Conclusion. Ses principaux déterminants sont : le nombre des transfusions sanguines et la durée d'HD ; d'où la nécessité de réduire les transfusions sanguines chez les sujets dialysés par l'administration d'EPO, étant donné le coût prohibitif du traitement contre le VHC dans notre contexte

RESUMO

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

RESUMO

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

RESUMO

Introduction: since the 1st case of coronavirus disease 2019 (COVID-19) in Kinshasa on March 10th 2020, mortality risk factors have not yet been reported. The objectives of the present study were to assess survival and to identify predictors of mortality in COVID-19 patients at Kinshasa University Hospital.Methods: a retrospective cohort study was conducted, 141 COVID-19 patients admitted at the Kinshasa University Hospital from March 23 to June 15, 2020 were included in the study. Kaplan Meier's method was used to described survival. Predictors of mortality were identified by COX regression models.Results: of the 141 patients admitted with COVID-19, 67.4 % were men (sex ratio 2H:1F); their average age was 49.6±16.5 years. The mortality rate in hospitalized patients with COVID-19 was 29% during the study period with 70% deceased within 24 hours of admission. Survival was decreased with the presence of hypertension, diabetes mellitus, low blood oxygen saturation (BOS), severe or critical stage disease. In multivariate analysis, age between 40 and 59 years [adjusted Hazard Ratio (aHR): 4.07; 95% CI: 1.16 - 8.30], age at least 60 years (aHR: 6.65; 95% CI: 1.48-8.88), severe or critical COVID-19 (aHR: 14.05; 95% CI: 6.3-15.67) and presence of dyspnea (aHR: 5.67; 95% CI: 1.46-21.98) were independently and significantly associated with the risk of death.Conclusion: older age, severe or critical COVID-19 and dyspnea on admission were potential predictors of mortality in patients with COVID-19. These predictors may help clinicians identify patients with a poor prognosis

RESUMO

Contexte & objectif. Le syndrome d'apnées du sommeil est une pathologie fréquemment sous diagnostiquée et souvent méconnue; particulièrement à cause d'une accessibilité insuffisante au gold-standard du diagnostic, la polysomnographie ou la polygraphie ventilatoire. Et pourtant, l'affection est responsable des complications surtout cardiovasculaires majeures. L'objectif de la présente étude était d'évaluer le niveau de performance de l'oxymétrie nocturne dans le diagnostic du syndrome d'apnées du sommeil. Méthodes. Enquête transversale menée entre le 1er janvier 2016 et le 30 septembre 2017. Tous les patients hospitalisés pour suspicion du syndrome d'apnées du sommeil ont bénéficié d'une oxymétrie nocturne et d'une polygraphie ventilatoire. Les logiciels Excel 2010 et SSPSS 21.0 ont permis d'analyser les données. Nous avons déterminé la sensibilité, la spécificité, la valeur prédictive positive et la valeur prédictive négative. La courbe ROC a été calculée. p < 0,05. Résultats. Au total 201 patients d'âge moyen de 64,6±11,8 ans, avec une prédominance masculine (55%) et en majorité obèses (IMC moyen de 32kg/m²) ont été inclus. La sensibilité et la spécificité de l'oxymétrie nocturne sont respectivement de 87 et de 85% avec une courbe ROC montrant une surface importante sous la courbe de 0,75. Conclusion. Avec sa sensibilité et spécificité élevées, l'oxymétrie nocturne peut constituer une alternative valable au diagnostic du syndrome d'apnées du sommeil. Son innocuité et sa bonne acceptabilité en font un outil facilement exportable et recommandable en cas de carence de moyens appropriés
