Mortalité à long terme des survivants d'accidents vasculaires cérébraux ischémiques à Bobo Dioulasso, Burkina Faso / Long-term mortality of ischaemic stroke survivors in Bobo-Dioulasso, Burkina Faso

Contexte et objectif. La survie à long terme des accidents vasculaires cérébraux ischémiques (AVCI) reste un défi majeur. L'objectif de ce travail était d'analyser la mortalité à long terme des survivants d'AVCI. Méthodes. Il s'est agi d'une cohorte rétrospective portant sur les patients hospitalisés du 1er janvier 2017 au 31 décembre 2019, sortis vivants du service de neurologie au Centre Hospitalier Universitaire Sourô Sanou de Bobo-Dioulasso après un AVCI. Nous avons recouru aux méthodes de Kaplan Meier et la regression de Cox pour décrire respectivement la survie et les prédicteurs de la mortalité. Résultats. Au total, 87 patients dossiers ont été colligés. L'âge moyen était de 61,2 ans (±13,7). Le sex-ratio M/F était de 1,23/1. L'hypertension artérielle était le principal facteur de risque cardiovasculaire (65,5 %). Les antécédents de cardiopathies étaient présents chez 6 patients. La conscience était normale chez 82 patients et les complications de décubitus ont été observées chez 20 patients au cours de l'hospitalisation. La durée moyenne d'hospitalisation était de 15,8 jours. La mortalité cumulée en post hospitalisation était de 40,2 % à 4 ans. Les facteurs prédictifs de la mortalité étaient l'âge > 60 ans (p=0,008; HRa= 3,05 ; IC 95 % : 1,33-6,99), le score de Glasgow>9 (p<0,001; HRa = 0,09; IC 95 % : 0,02-0,31) et l'absence de complication de décubitus (p=0,009; HRa = 0,34; IC95 % : 0,15-0,76). Conclusion. Dans ce contexte, la mortalité à long terme des AVCI est élevée. Le renforcement du suivi vis-à-vis des groupes spécifiques pourrait contribuer à réduire considérablement cette mortalité à long terme.

Context and objective. Long-term survival from ischaemic stroke remains a major challenge. The aim of this study was to analyse the long-term mortality of stroke survivors at the Sourô Sanou University Hospital in Bobo-Dioulasso. Methods. This was a retrospective cohort of hospitalized patients from January 1, 2017 to December 31, 2019, discharged alive from the neurology service after ischaemic stroke. We used Kaplan Meier and Cox regression methods to describe survival and predictors of mortality, respectively. Results. A total of 87 patients were included in this study. The mean age was 61.2 years (±13.7). The sex ratio M/F was 1.23. Hypertension was the main cardiovascular risk factor (65.5%). A history of heart disease was present in 6 patients (6.9%). Consciousness was normal in 82 patients (94.2%) and decubitus complications were observed in 20 patients (23%) during hospitalisation. The average length of hospital stay was 15.8 days. Cumulative post-hospital mortality was 40.2% at 4 years. Factors predictive of mortality were age >60 years (p=0.008; aHR= 3.05; 95%CI: 1.33-6.99), Glasgow score>9 (p<0.001; aHR = 0.09; 95% CI: 0.02-0.31) and absence of decubitus complication (p=0.009; aHR = 0.34; 95%CI: 0.15-0.76). Conclusion. In this context, long-term mortality in ischaemic stroke is high. Closer monitoring of specific groups could help to reduce considerably this long-term mortality.

Objectif. L'apparition de plusieurs cas de pneumopathie d'origine inconnue en Chine a conduit à l'identification du SARS-CoV-2. L'objectif de ce travail était de décrire le profil épidémioclinique et évolutif des patients hospitalisés dans notre centre de prise en charge afin de contribuer à l'amélioration de la lutte contre cette pandémie. Population et Méthodes. Il s'est agi d'une étude de cohorte rétrospective qui s'est déroulée du 19 mars au 31 septembre 2020 au CHUSS de Bobo Dioulasso. Résultats. Au total, 44 patients ont été inclus dans l'étude. La moyenne d'âge des patients était de 46,8 ans [14-84 ans]. Le sex ratio était de 0,7. La tranche d'âge la plus représentée était celle 50 et 64 ans avec 38,4% des patients. Les patients diabétiques et hypertendus représentaient respectivement 25% et 29,5% des cas. Les principaux symptômes étaient la dyspnée, la fièvre et la toux notées respectivement chez 54,5%, 54,5 % et 47,7% des cas. A la radiographie thoracique, les opacités de type micronodulaire étaient les plus représentées dans 66,7% des cas. L'oxygénothérapie a été nécessaire dans 38,6% des cas. Le protocole Covid-19 en vigueur dans le pays était instauré chez 90,9% des cas. Avec une durée d'hospitalisation moyenne de 12,4 jours, l'évolution clinique a été marquée par un décès chez 22,7 % des cas. Conclusion. Dans notre contexte, cette maladie reste l'apanage des sujets âgés présentant des comorbidités. L'une de difficultés de sa prise en charge était l'insuffisance du plateau technique expliquant en grande partie ce fort taux de létalité.

The aim of this study was to describe the epidemiological and clinical profile of patients admitted to our care center to contribute to the improvement of the control of this pandemic. Population and methods. This was a retrospective cohort study which took place from 19 March to 31 September 2020 at the CHUSS of Bobo Dioulasso. Results. A total of 44 patients were included in the study. The mean age of the patients was 46.8 years [14- 84 years]. The sex ratio was 0.7. The most represented age group was 50-64 years with 38.4% of patients. Diabetic and hypertensive patients represented 25% and 29.5% of the cases respectively. The main symptoms were dyspnea, fever and cough, which were noted in 54.5%, 54.5% and 47.7% of cases respectively. On chest X-ray, micronodular opacities were the most common in 66.7% of cases. Oxygen therapy was required in 38.6% of cases. The Covid-19 protocol in force in the country was implemented in 90.9% of cases. With an average hospital stay of 12.4 days, the clinical course was marked by death in 22.7% of cases. Conclusion. In our context, this disease remains the prerogative of elderly subjects with comorbidities. One of the difficulties of its management was the insufficiency of the technical platform explaining in large part this high rate of lethality.

Larvicidal Activity of Crude Extracts of Vernonia cinerea Less (Asteraceae) against the Larvae of Anopheles gambiae in Bobo Dioulasso, Burkina Faso

Aims: This study aims to evaluate the larvicidal activity of lyophilized methanolic extracts, hydro-methanolic extracts and aqueous extracts of Vernonia cinerea Less against the 3rd and 4th instars larvae of Anopheles gambiae. Place and Duration of Study: Pharmacognosy Laboratory, Department of Biomedical Sciences, Centre MURAZ /Research Institute for Health; Ministry of Health, Bobo-Dioulasso, between February 2017 and January 2018. Institut de Recherche en Sciences de la Santé/Direction Régionale de l’Ouest (IRSS) Bobo-Dioulasso, between March 2017 and January 2018. Methodology: The whole plant material was collected in Banfora, located at West of Burkina Faso. The 80% methanolic, 50/50% hydro-methanolic and aqueous extracts were obtained by using the classical natural product extraction method of the laboratory. Extracts were lyophilized and a series of concentrations of the extracts ranging from 0.001 – 100 mg/L were prepared. The larvicidal activity of lyophilized extracts has been tested against the 3rd and 4thAnopheles gambiae larvae. The larval mortality was evaluated after 24 hours and 48 hours of exposure. The percent of means of mortality was calculated. Lethal Concentration LC50 and LC90 values were determined. Results: In the laboratory, the results of methanolic extract at 100 mg/L achieved (100%) mortality against Anopheles gambiae after 24 hours of exposure.The same extract at 10 mg/L generated (95.85±1.26%) of mortality outside the laboratory. The 80% methanolic extract showed Lethal Concentration LC50 of 11.07 mg/L and Lethal Concentration LC90 of 81.38 mg/L (after 24 hours). The 50/50% hydro-methanolic extracts achieved Lethal Concentration LC50 of 22.27 mg/L against 3417.78 mg/L respectively inside and outside of the laboratory. Conclusion: The methanolic extract is the most effective in killing on the larvae compared to the other extracts tested. Vernonia cinerea Less possesses larvicidal activity against Anopheles gambiae larvae. It may be a possible source of mosquito vector control. This study provided promising finding for using crude extracts of Vernonia cinerea Less in controlling larvae of malaria vectors.

Digestive fungal flora in asymptomatic subjects in Bobo-Dioulasso, Burkina Faso

Objective: To identify Candida species in asymptomatic subjects in Bobo-Dioulasso (Burkina Faso) by the matrix-assisted laser desorption ionization-time of flight mass spectrometry. Methods: A cross-sectional study was conducted from January to February 2013 in Bobo-Dioulasso to collect fecal and urine specimens from voluntary donors. Fungal strains were isolated on Sabouraud dextrose agar and analyzed using matrix-assisted laser desorption ionisation-time-of-flight mass spectrometry. Results: A total of 135 samples including stools (78.5%, 106/135) and urine (21.5%, 29/135) were analyzed. The results revealed that fecal specimens contained mainly Candida krusei (C. krusei) (42.5%) followed by Candida albicans (29.3%), Candida glabrata (18.0%) and Candida tropicalis (C. tropicalis) (4.7%). C. krusei (34.6%) was also found to be the most frequently identified in urine samples followed by Candida albicans (27.0%), C. tropicalis (15.4%) and Candida parapsilosis. However, uncommon species such as Candida nivariensis, Candida kefyr, Candida norvegensis, Candida parapsilosis, Candida lusitaniae and Candida robusta were also identified from fecal and urines samples. Conclusions: This study noted the emergence of species such as C. krusei, Candida glabrata, Candida parapsiolosis, C. tropicalis, Candida nivariensis, Candida norvegensis, and others. It is an imperative to take into account the existence of these species in the therapeutic management of patients in Bobo-Dioulasso.
