Facteurs associes aux décès des nouveau-nés suspects d’infections bactériennes au Centre Hospitalier Universitaire Pédiatrique Charles de Gaulle de Ouagadougou, Burkina Faso

RésuméIntroduction: il s'agit d'étudier les facteurs associés au décès des nouveau-nés suspects d'infections bactériennes au centre hospitalier universitaire pédiatrique Charles de gaulle de Ouagadougou. Méthodes: nous avons mené une étude de cohorte rétrospective du 1er janvier 2009 au 31 décembre 2012 au centre hospitalier universitaire pédiatrique Charles de gaulle de Ouagadougou. Résultats: la fréquence hospitalière des nouveau-nés suspects d'infection bactérienne sur était de 62,8%. L'âge médian à l'admission était de trois jours et le sex ratio de 1,1.Parmi ces nouveau-nés, 351 (22,8%) ont bénéficié d'au moins un examen bactériologique, et 28 (8%) ont eu la confirmation de l'origine bactérienne de l'infection. Au cours de la période néonatale, 138(9%) nouveau-nés sont décédés avec un taux de létalité précoce et tardive respectivement de 9,6% et 8,3%. Le lieu de résidence, le mode d'admission, le nombre de consultations prénatales, le poids de naissance, la présence de signes de gravité et l'année d'admission étaient les facteurs de risque indépendants associés au décès. Conclusion: les facteurs associés au décès devraient être pris en compte dans les interventions de santé pour réduire la mortalité néonatale.English abstractIntroduction: the aim of this study was to analyze factors associated with death in newborns suspected of bacterial infections in pediatric teaching hospital of Charles de Gaulle Ouagadougou. Methods: we conducted a retrospective cohort study from 1 January 2009 to 31 December 2012 in pediatric teaching hospital of Charles de Gaulle Ouagadougou. Results: the hospitalization rate for newborns suspected of bacterial infection was 62.8%. The average age at admission was three days and the sex ratio was 1.1. Of these newborns, 351 (22.8%) underwent at least one bacteriological examination, and 28 (8%) had confirmation of bacterial infection. During the neonatal period, 138 (9%) newborns died with early and late case fatality rate of 9.6% and 8.3% respectively. Place of residence, mode of admission, number of prenatal consultations, birth weight, presence of severe signs and year of admission were independent risk factors associated with death.Conclusion: factors associated with death should be taken into account in health interventions to reduce neonatal mortality.Key words: Newborn, bacterial infection, bacteriology, risk factors, deat

Meningitis Dipstick Rapid Test: Evaluating Diagnostic Performance during an Urban Neisseria meningitidis Serogroup A Outbreak, Burkina Faso, 2007

Meningococcal meningitis outbreaks occur every year during the dry season in the “meningitis belt” of sub-Saharan Africa. Identification of the causative strain is crucial before launching mass vaccination campaigns, to assure use of the correct vaccine. Rapid agglutination (latex) tests are most commonly available in district-level laboratories at the beginning of the epidemic season; limitations include a short shelf-life and the need for refrigeration and good technical skills. Recently, a new dipstick rapid diagnostic test (RDT) was developed to identify and differentiate disease caused by meningococcal serogroups A, W135, C and Y. We evaluated the diagnostic performance of this dipstick RDT during an urban outbreak of meningitis caused by N. meningitidis serogroup A in Ouagadougou, Burkina Faso; first against an in-country reference standard of culture and/or multiplex PCR; and second against culture and/or a highly sensitive nested PCR technique performed in Oslo, Norway. We included 267 patients with suspected acute bacterial meningitis. Using the in-country reference standard, 50 samples (19%) were positive. Dipstick RDT sensitivity (N = 265) was 70% (95%CI 55–82) and specificity 97% (95%CI 93–99). Using culture and/or nested PCR, 126/259 (49%) samples were positive; dipstick RDT sensitivity (N = 257) was 32% (95%CI 24–41), and specificity was 99% (95%CI 95–100). We found dipstick RDT sensitivity lower than values reported from (i) assessments under ideal laboratory conditions (>90%), and (ii) a prior field evaluation in Niger [89% (95%CI 80–95)]. Specificity, however, was similar to (i), and higher than (ii) [62% (95%CI 48–75)]. At this stage in development, therefore, other tests (e.g., latex) might be preferred for use in peripheral health centres. We highlight the value of field evaluations for new diagnostic tests, and note relatively low sensitivity of a reference standard using multiplex vs. nested PCR. Although the former is the current standard for bacterial meningitis surveillance in the meningitis belt, nested PCR performed in a certified laboratory should be used as an absolute reference when evaluating new diagnostic tests
