Évaluation du Risque Cardiovasculaire Absolu Chez les Patients Hémodialysés Diabétiques et Non diabétiques au Centre National d’Hémodialyse de Donka Conakry
Le risque cardiovasculaire chez les hémodialysés semble varier en fonction du statut diabétique ainsi que d’autres facteurs associés et constitue un problème de santé publique en Afrique en général et particulièrement en Guinée. Dans ce sens, l’objectif de cette étude était d’évaluer le risque de survenue d’une pathologie cardiovasculaire absolu chez les patients hémodialysés diabétiques, par rapport aux patients hémodialysés non diabétiques. La présente, étude transversale, descriptive et analytique a été réalisée entre le 1 ier avril et le 30 juin 2019 au Centre National d’Hémodialyse de Donka. L’étude a inclus les 140 patients hémodialysés durant la période. Le recrutement était exhaustif et concernait tous les patients hémodialysés répondant aux critères de sélection. Les données ont été recueillies prospectivement chez les patients hémodialysés puis compilées et traitées dans Epi info. 7.2.2.6. Un questionnaire semi-administré a été utilisé à ce fin. Pour évaluer le risque cardiovasculaire chez les patients le FRAMINGHAM RISK SCORE (FRS) a été aussi utilisé. L’enquête a concerné 140 individus dont 91 (65,00%) étaient des hommes, contre 49 (35,00%) de femmes, soit un sex- ratio de 1,86 soit 2 hommes pour une femme. L’âge moyen était de 41 ± 4,1 ans avec des extrêmes de (30 ; 74) ans. On notait une prédominance chez les hommes des facteurs de risque, pour le tabagisme. L’étude a trouvé 39 diabétiques contre 101 non diabétiques. Le risque était élevé chez 23 diabétiquessur 39 ; et 25 sur 101 des patients non diabétiques. L’étude montre qu’un patient sur quatre aurait un risque absolu élevé chez les patients non diabétiques et un patient sur deux chez les patients diabétiques. Ce risque est majoré par d’autres facteurs associés.
Introduction: Cardiovascular risk in hemodialysis appears to vary depending on diabetic status and other associated factors and is a public health problem in Africa in general and particularly in Guinea. The objective of this study was to assess the risk of absolute cardiovascular disease in diabetic hemodialysis patients, compared to non-diabetic hemodialysis patients. Methods: Between April 1 and June 30, 2019, a descriptive and analytical cross-sectional study was conducted at the National Hemodialysis Centre in Donka. The study included 140 hemodialysis patients during the period. Recruitment was comprehensive and involved all hemodialysis patients meeting the selection criteria. The data were collected prospectively in hemodialysis patients and then compiled and processed in Epi info. 7.2.2.6. A semi-administered questionnaire had been used. To assess cardiovascular risk in patients, FRAMINGHAM RISK SCORE (FRS) was used. Results: The survey involved 140 individuals, 91 of whom (65.00%) 49 (35.00%) were men. sex ratio of 1.86 or 2 men per woman. The average age was 41-4.1 years with extremes of (30; 74) years. There was a predominance among men of risk factors for smoking. The study found 39 diabetics versus 101 non-diabetics. The risk was high in 23 out of 39 diabetics; and 25 out of 101 non-diabetic patients. Conclusion: The study shows that one in four patients would have a high absolute risk in diabetic and non-diabetic patients and also confirms the association of other factors that increase this risk. The survey involved 140 individuals, 91 of whom (65.00%) 49 (35.00%) were men. sex ratio of 1.86 or 2 men per woman. The average age was 41-4.1 years with extremes of (30; 74) years. There was a predominance among men of risk factors for smoking and diabetes. In our series, most of our patients had a low risk level of 56 (40%). Conclusion: This survey finds a low risk in this hemodialysis population. This should lead to strengthening strategies for preventing cardiovascular disease in this at-risk population
A community-based contact isolation strategy to reduce the spread of Ebola virus disease: an analysis of the 2018-2020 outbreak in the Democratic Republic of the Congo
Introduction: Despite tremendous progress in the development of diagnostics, vaccines and therapeutics for Ebola virus disease (EVD), challenges remain in the implementation of holistic strategies to rapidly curtail outbreaks. We investigated the effectiveness of a community-based contact isolation strategy to limit the spread of the disease in the Democratic Republic of Congo (DRC).
Methods: We did a quasi-experimental comparison study. Eligible participants were EVD contacts registered from 12 June 2019 to 18 May 2020 in Beni and Mabalako Health Zones. Intervention group participants were isolated to specific community sites for the duration of their follow-up. Comparison group participants underwent contact tracing without isolation. The primary outcome was measured as the reproduction number (R) in the two groups. Secondary outcomes were the delay from symptom onset to isolation and case management, case fatality rate (CFR) and vaccination uptake.
Results: 27 324 EVD contacts were included in the study; 585 in the intervention group and 26 739 in the comparison group. The intervention group generated 32 confirmed cases (5.5%) in the first generation, while the comparison group generated 87 (0.3%). However, the 32 confirmed cases arising from the intervention contacts did not generate any additional transmission (R=0.00), whereas the 87 confirmed cases arising from the comparison group generated 99 secondary cases (R=1.14). The average delay between symptom onset and case isolation was shorter (1.3 vs 4.8 days; p<0.0001), CFR lower (12.5% vs 48.4%; p=0.0001) and postexposure vaccination uptake higher (86.0% vs 56.8%; p<0.0001) in the intervention group compared with the comparison group. A significant difference was also found between intervention and comparison groups in survival rate at the discharge of hospitalised confirmed patients (87.9% vs 47.7%, respectively; p=0.0004).
Conclusion: The community-based contact isolation strategy used in DRC shows promise as a potentially effective approach for the rapid cessation of EVD transmission, highlighting the importance of rapidly implemented, community-oriented and trust-building control strategies.</p
