Predictors of in-hospital mortality for stroke in douala, cameroon.

Background. The objective of this study was to describe complications in hospitalized patients for stroke and to determine the predictive factors of intrahospital mortality from stroke at the Douala General Hospital (DGH) in Cameroon. Patients and Methods. A prospective cross-sectional study was carried out from January 1, 2010 to December 31, 2012, at the DGH. All the patients who were aged more than 15 years with established diagnosis of stroke were included. A univariate analysis was done to look for factors associated with the risk of death, whilst the predictive factors of death were determined in a multivariate analysis following Cox regression model. Results. Of the 325 patients included patients, 68.1% were males and the mean age was 58.66 ± 13.6 years. Ischaemic stroke accounted for 52% of the cases. Sepsis was the leading complications present in 99 (30.12%) cases. Independent predicting factors of in-hospital mortality were Glasgow Coma Scale lower than 8 (HR = 2.17 95% CI 4.86-36.8; P = 0.0001), hyperglycaemia at admission (HR = 3.61 95% CI 1.38-9.44; P = 0.009), and hemorrhagic stroke (HR = 5.65 95% CI 1.77-18; P = 0.003). Conclusion. The clinician should systematically diagnose and treat infectious states and hyperglycaemia in stroke.

[Survival of comatose stroke victims in a neurological department in Dakar]. / Survie des accidents vasculaires cérébraux comateux à Dakar (Sénégal).

BACKGROUND: In Dakar, stroke is the most frequent neurological disease with the highest mortality. Victims may present in a critical state of coma. The objective of this study was to evaluate survival among comatose stroke patients in Dakar, Senegal. METHODS: This was a longitudinal prospective study from April 2006 to July 2007 conducted in the Neurological Intensive Care Unit (NICU) of Fann University Teaching Hospital in Senegal. Were included in the study, all stroke patients confirmed by CT scan with a Glasgow coma score less than or equal to 8/15. Patients with subarachnoid hemorrhage were excluded. RESULTS: A total of 105 patients were evaluated with 54 cases of ischemic stroke among them. The mean age was 61.87+/-14.16 years. The mean duration of hospital stay in the NICU was 10.82+/-11 days with an estimated mortality of 82.9%; the three-month survival was 9.52%. The median overall survival was 7+/-1 days (CI(95%): 5-9). CONCLUSION: Comatose stroke patients have a poor prognosis, emphasizing the crucial importance of primary prevention.

[Prognosis of intracerebral hemorrhage with coma in a neurological critical care unit in the tropics]. / Pronostic des hémorragies intracérébrales avec coma dans une unité de neuroréanimation tropicale.

Thirty-five percent of stroke events observed in Dakar, Senegal involve hemorrhaging. Coma is a frequent revealing sign of the disease and a severe prognostic factor. Since specific therapy is unavailable in sub-Saharan Africa, only symptomatic medical treatment is proposed to most patients presenting intracerebral hemorrhage. The purpose of this longitudinal study was to evaluate prognosis and survival in patients presenting with intracerebral hemorrhage in a neurological critical care unit in Senegal. Study was conducted from April 15, 2006 to July 18, 2007 in the neurological critical unit of the Fann University Hospital Center in Dakar. Mortality and probability of survival were estimated using Kaplan Meier methods. The predictive value of factors significantly correlated with prognosis was determined by multivariate analysis using a Cox proportional hazards model. A total of 51 cases of intracerebral hemorrhage were included in this study. Mean patient age was 64 years and the sex ratio was 1.13. Median survival was 7 days and mortality in the neurological critical care unit was 80.4%. The probability of survival at days 10, 30 and 90 were 43.14%, 21.57% and 13.73% respectively. Occurrence of a complication on day 3 was shown to be an independent risk factor for early death. Intracerebral hemorrhage with coma is associated with a high mortality rate. Better primary prevention is necessary.

Pronostic des hemorragies intracerebrales avec coma dans une unite de neuroreanimation tropicale

Trente cinq pour cent des accidents vasculaires cerebraux sont de nature hemorragique a Dakar. Le coma constitue souvent un mode de revelation de la maladie et un facteur de gravite. En l'absence de therapeutique specifique en Afrique subsaharienne; seul un traitement medical symptomatique est propose en general aux patients victimes d'hemorragie cerebrale. Le but de l'etude etait d'etudier la survie et d'evaluer le pronostic des hemorragies cerebrales avec coma dans une unite de neuroreanimation senegalaise. Il s'agissait d'une etude longitudinale qui s'etait deroulee du 15 avril 2006 au 18 juillet 2007 a l'unite de neuroreanimation du Centre Hospitalier Universitaire de Fann a Dakar. Les taux de mortalite et la probabilite de survie etaient estimes par la methode de Kaplan Meier. L'effet des variables significativement associees au pronostic etait etudie en analyse multivariee a l'aide d'un modele des risques proportionnels de Cox. Cinquante et un cas d'hemorragie intracerebrale etaient inclus avec une mediane d'age de 64 ans et un sex ratio de 1;13. La mediane de survie etait de 7 jours et la mortalite en neuroreanimation etait de 80;4. Les probabilites de survie a J10; J30 et J90 etaient respectivement de 43;14; 21;57et 13;73. L'existence de complications a J3 etait apparue comme facteur independant de mortalite precoce. Les hemorragies intracerebrales avec coma sont associees a une mortalite elevee et soulignent l'interet de la prevention primaire
