Profil comparatif et évolutif des personnes infectées par le virus de l’immunodéficience humaine traitées aux antirétroviraux à Kinshasa, République Démocratique du Congo

Introduction: a trithérapie (ARV) introduite en R.D.Congo en 1996, a permis l´amélioration substantielle de la qualité de vie des PVVIH et a réduit la morbimortalité liée au sida en R.D. Congo. L'objectif de cette étude est de présenter le profil épidémiologique comparatif, clinique, ainsi que l'évolution anthropométrique des PVVIH sous ARV à Kinshasa. Méthodes: étude de cohorte sur 438 PVVIH, de 18 ans et plus, suivies entre mai 2010 à 2011 à Amo Congo à Kinshasa. Une comparaison a été faite entre les patients suivis pendant un an et ceux perdus de vue. Le Chi carré de Mc Nemar et l'analyse de variance pour mesures répétées ont été appliqués pour étudier l'évolution. Résultats: près 12 mois de suivi, 11,4% de patients ont été perdus de vue. Parmi eux, on observait des proportions significativement plus élevées de personnes de niveau socioéconomique bas, d'indice de masse corporelle (IMC) bas, présentant de l'anorexie, des affections opportunistes. Les proportions de patients aux stades OMS 3 & 4 et naïfs étaient également significativement plus élevées et la durée sous ARV plus courte. Les gains moyens des paramètres anthropométriques au 12ème mois, étaient importants : de 3,6 [3,2 - 4,0] kg pour le poids, 1,8 (1,4 - 2,3) cm pour le périmètre abdominal, 0,9 (0,8 - 1,2) cm pour le périmètre brachial, 1,4 (1,2 - 1,5) kg/m2 pour l'IMC. La proportion de patients avec un IMC <18,5 kg/m2 a significativement plus baissé entre l'admission et le 12ème mois parmi les patients sans stomatite que parmi ceux avec stomatite. L'IMC moyen évoluait significativement différemment entre l'admission et le 12ème mois selon l'âge et la taille de ménage. Conclusion: les facteurs fragilisant la rétention des patients sous antirétroviraux et une évolution progressive de l'état nutritionnel ont été observés

La recherche en santé

Les activités de recherche font partie du modèle de coopération développé par le Cemubac. Les fondements de la recherche sont établis sur le renforcement du fonctionnement des systèmes et des services de santé aboutissant à l’amélioration de la qualité des prestations offertes aux communautés. Qu’elle soit quantitative ou qualitative, cette recherche à composante participative élevée a pu se développer à la faveur d’un partenariat établi avec les acteurs, qu’ils soient professionnels ou bénéficiaires. Elle s’appuie largement sur une implication de cadres institutionnels formés à cet effet et repose sur une présence inscrite dans la durée. La recherche menée au Kivu a été conduite depuis plus de quinze ans dans un climat de dégradation de l’environnement économique, social et surtout sécuritaire. Appareil d’acquisition de connaissances, la recherche développée au Kivu reste avant tout orientée vers l’amélioration de l’offre des services.Research activities are part of the cooperation model developed by the Cemubac. The foundation for the research is based on strengthening the capacity of health systems and services resulting in the improvement of care offered to communities. The research (quantitative and qualitative) has a high participatory dimension and was able to develop thanks to partnerships with professionals and beneficiaries. It relies heavily on the implication of national public staff trained specifically for this work and on long-term presence in the area. The work in Kivu has continued over the past fifteen years despite a deteriorating social, economic and security context. As an organism for acquiring knowledge, the Cemubac’s work in Kivu is primarily geared towards improving health services

Community volunteers can improve breastfeeding among children under six months of age in the Democratic Republic of Congo crisis

<p>Abstract</p> <p>Background</p> <p>Malnutrition is a major public health problem in developing countries and exclusive breastfeeding is an efficient strategy that can be used to prevent malnutrition and reduce child mortality. The objective of this study is to evaluate the effectiveness of community volunteers in promoting exclusive breastfeeding from birth in an area of endemic malnutrition.</p> <p>Methods</p> <p>This evaluation analyzed the impact of the community-based nutrition project in Katana health district of the Democratic Republic of Congo from 2004 to 2006. Each of the villages in this sector had a nutritional village committee made up of five members responsible for continuously working to raise awareness of the importance of exclusive breastfeeding from birth among pregnant women and community leaders in their respective villages. The program worked with community volunteers with a mean age of 37 years, most of whom were married (86%). Eighty percent of the community volunteers had completed secondary school or a higher level of education. Data related to the period of exclusive breastfeeding and to the number of visits made to the health services for 208 children. The data were compared with data from 178 infants collected from another health sector, which had never developed a community-based nutrition program.</p> <p>Results</p> <p>The duration of exclusive breastfeeding from birth (median, range) was 6 months (2 to 7) in the intervention area compared with 4 months (1 to 6) in the comparison area (p < 0.001). The proportion of infants receiving exclusive breastfeeding at six months of age was higher in the intervention area than in the comparison area: 57.7% (95% Confidence Interval, CI, 50.9 to 64.5) versus 2.7% (95%CI, 1.1 to 6.6) (p < 0.001). The intervention group had a higher mean weight at 12 months (standard deviation): 8.42 kg (1.41) compared to 7.97 kg (1.02), although this difference was not statistically significant (p = 0.055).</p> <p>Conclusions</p> <p>The promotion of breastfeeding by community volunteers in an area of endemic malnutrition in rural Democratic Republic of Congo increased the duration of exclusive breastfeeding from birth.</p

Malaria Lethality in Children under 5 Years of Age and Study of Risk Factors in MbujiMayi Paediatric Environment, a Neglected Deadly Epidemic in the Democratic of Republic of Congo

The objective of this study was to determine the risk factors for malaria lethality in the MbujiMayi paediatric environment, a follow-up study of hospitalised cases over 5 years was conducted between January 2016 and December 2020 in the four hospitals. The case rate was 6.9% for the total (139 cases of death for 2017 cases of severe malaria for 5 years,) and varied from year to year (10.7% in 2016 to 4.6% in 2020). Cox Proportional Risk Model results including significant covariates in multivariate analysis [HR (IC95%)]. In multivariate analysis, two models were considered. The case-fatality rate was independently associated with late arrival after 48 hours [3.1 (1.9–5.1); p < 0.001], types of pre-hospital recourse such as recourse to the church [1.4 (1.1–2.1),; p = 0.042) and tradipractor [3.2 (1.8–6.1); p < 0.001] for severe malaria, children under 12 months of age [1.8 (1.2–2.8); p < 0.001], those with circulatory collapse [2.6 (1.1–6.1); p < 0.001] and those in deep coma [1.9 (1.1–3.4); p = 0.016]. The second model with the number of associated syndromes, showed that the risk was 1.7 plus for children with a complex clinical picture, made up of the combination of several signs [1.7 (1.1–2.6); p < 0.001]. These results highlight the need for more information campaigns to encourage people to seek institutional care for malaria. Our results also suggest that prophylactic treatment may be advisable for children under 5 years of age

Malaria and Iron Load at the First Antenatal Visit in the Rural South Kivu, Democratic Republic of the Congo: Is Iron Supplementation Safe or Could It Be Harmful?

We investigated the relationship between malaria infection and iron status in 531 pregnant women in South Kivu, Democratic Republic of the Congo. Sociodemographic data, information on morbidity, and clinical data were collected. A blood sample was collected at the first antenatal visit to diagnose malaria and measure serum ferritin (SF), soluble transferrin receptor, C-reactive protein, and α1-acid-glycoprotein. Malaria prevalence was 7.5%. Median (interquartile range) SF (adjusted for inflammation) was significantly higher in malaria-infected (82.9 μg/L [56.3-130.4]) than in non-infected (39.8 μg/L [23.6-60.8]) women (P < 0.001). Similarly, estimated mean body iron store was higher in malaria-infected women (P < 0.001). Malaria was significantly and independently associated with high levels of SF. Efforts to improve malaria prevention while correcting iron deficiency and anemia during pregnancy are warranted

Definition and characterization of localised meningitis epidemics in Burkina Faso: a longitudinal retrospective study

<p>Abstract</p> <p>Background</p> <p>The epidemiology of meningococcal meningitis in the African meningitis belt is characterised by seasonality, localised epidemics and epidemic waves. To facilitate research and surveillance, we aimed to develop a definition for localised epidemics to be used in real-time surveillance based on weekly case reports at the health centre level.</p> <p>Methods</p> <p>We used national routine surveillance data on suspected meningitis from January 2004 to December 2008 in six health districts in western and central Burkina Faso. We evaluated eight thresholds composed of weekly incidence rates at health centre level for their performance in predicting annual incidences of 0.4%and 0.8% in health centre areas. The eventually chosen definition was used to describe the spatiotemporal epidemiology and size of localised meningitis epidemics during the included district years.</p> <p>Results</p> <p>Among eight weekly thresholds evaluated, a weekly incidence rate of 75 cases per 100,000 inhabitants during at least two consecutive weeks with at least 5 cases per week had 100% sensitivity and 98% specificity for predicting an annual incidence of at least 0.8% in health centres. Using this definition, localised epidemics were identified in all but one years during 2004-2008, concerned less than 10% of the districts' population and often were geographically dispersed. Where sufficient laboratory data were available, localised epidemics were exclusively due to meningococci.</p> <p>Conclusions</p> <p>This definition of localised epidemics a the health centre level will be useful for risk factor and modelling studies to understand the meningitis belt phenomenon and help documenting vaccine impact against epidemic meningitis where no widespread laboratory surveillance exists for quantifying disease reduction after vaccination.</p
