Evolution clinique et biologique des enfants infectés par le VIH sous traitement antirétroviral à Lubumbashi, République Démocratique du Congo

Introduction: en 2014, moins de 3 enfants sur dix (823 000 enfants environ) vivant avec le VIH avaient accès à un traitement antirétroviral (TAR), contre plus de quatre adultes sur dix. En conséquence, les enfants survivants qui ont une chance d´accéder au TAR sont traités souvent tardivement, à un stade avancé de la maladie. À Lubumbashi (RDC), les études sur l´évaluation du TAR chez l´enfant sont quasi nulles. Cette étude avait comme objectif décrire les caractéristiques sociodémographiques, cliniques, immunologiques et thérapeutiques des enfants infectés par le VIH et sous TAR et identifier les facteurs associés à un échec thérapeutique. Méthodes: il s'agit d'une étude transversale, réalisée du 1er janvier au 31 mars 2015 et portant sur une cohorte d'enfants de moins de 15 ans infectés par le VIH, suivis dans le service de Pédiatrie de l´hôpital Jason Sendwe. Résultats: 62 enfants âgés de moins de 15 ans infectés par le VIH ont été mis sous TAR. Les filles étaient prédominants (54,8%). 83,9% étaient à un stade clinique avancé (3 ou 4) lors de l´initiation au TAR. Notre étude montre que l´échec thérapeutique était significativement associé à l´âge ≥10 ans lors de l´évaluation de la prise en charge. Conclusion: l´étude a permis de montrer le retard avec lequel la prise en charge de l´enfant infecté VIH à Lubumbashi s´effectue; suggérant ainsi un renforcement du programme de la PTME et un dépistage précoce en vue d´une prise en charge précoce et la mise en place d´un mécanisme de rétention des enfants suivis

Severe malaria and death risk factors among children under 5 years at Jason Sendwe Hospital in Democratic Republic of Congo.

INTRODUCTION: Malaria is still a major public health concern in the Democratic Republic of Congo. Its morbidity and mortality challenge the actual strategies of the fight agains malaria. This study was aimed to describe the epidemiology, the clinical caracteristics and the risk factors of death associated to severe malaria in the pediatric population under 5 years at Sendwe Hospital of Lubumbashi. METHODS: This analytical retrospective study was conducted in Lubumbashi, in the province of Haut-Katanga. All patients under 5 years hospitalized for severe malaria were registered from January 2014 to December 2016. RESULTS: Among the 3,092 patients hospitalised during our study period, 452 (14.6%) were admitted for severe malaria. The average age was 27.04 months, the male sex was the most affected (53.54% with the sex-ratio 1.15). The most frequent forms of gravity noticed were cerebral malaria (48.23%) and severe anemia (46.90%). Death was noted in the evolution in 28.32%. Repeated convulsion (OR = 2.27; 95% CI: 1.47-3.48), coma (OR = 3.55; 95% CI: 2.19-5.74) and severe acute malnutrition (OR = 3.32; 95% CI: 1.56-7.06) were asscociated with a high risk of death. CONCLUSION: This research shows that severe malaria is still an important cause of morbidity and mortality among young children in Lubumbashi. Neurologic and anemic forms are the most frequent. The predictive signs of death are: repeated convulsions, coma and severe acute malnutrition.

[Seroprevalence and factors associated with Voluntary Counselling and Testing (VCT) for HIV among children in Lubumbashi, Democratic Republic of the Congo]. / Séroprévalence et facteurs associés à l'acceptation du Conseil et Dépistage Volontaire du VIH chez l'enfant à Lubumbashi, République Démocratique du Congo.

INTRODUCTION: Despite proposals for screening infants or preschool children for HIV infection, the proportion of children who grow or die with unknown HIV status is high in the Democratic Republic of the Congo (DRC). This study aimed to determine the seroprevalence during a voluntary screening and to identify factors associated with Voluntary Counselling and Testing (VCT) for HIV in the paediatric population of non-HIV infected or non-HIV exposed infants and children in Lubumbashi, DRC. METHODS: We conducted a cross-sectional prospective analytical study in 4 community VCT centers divided into 4 health zones in the city of Lubumbashi, DRC (Lubumbashi, Ruashi, Kampemba and Kenya) over the period 1 August 2006 - 31 September 2007. The study aimed to evaluate voluntary testing for HIV among children less than 15 years. The sociodemographic characteristics and the parameters related to Voluntary Counselling and Testing (VCT) for HIV were analyzed. Usual descriptive statistical analyses and logistic regression were perfomed. RESULTS: Out of 463 children screened for HIV, 41 (8.9%; 95% CI: 6.5%-11.9%) were HIV positive. Voluntary Counselling and Testing (VCT) for HIV in the paediatric population of non-HIV infected or non-HIV exposed infants or children was significantly higher in children over 2 years of age (adjusted odds ratio (AOR)=3.6 [95% CI: 1,1-12,2]) when both of their parents had negative or uknown HIV status (AOR = 27.4 [95% CI: 9,4-80,0]), when either or both of their biological parents were alive (AOR = 24.9 [95% CI: 2,4-250,8]) and when screening programs were not only carried out by health professionals (AOR = 2.9 [95% CI: 1,0-7,9]). CONCLUSION: Our study shows a high HIV prevalence among children supporting the need for VCT highly accepted by parents and tutors in the city of Lubumbashi.
