• W3084421853 abstract "ABSTRACT Objectif. Les infections representent la premiere cause de morbidite et la deuxieme cause de mortalite chez les hemodialyses. Le portage nasal du Staphylococcus aureus joue un role preponderant dans la survenue de ces infections. L’objectif de notre etude etait de determiner la prevalence de ce portage nasal chez les patients hemodialyses et le personnel du centre. Patients et methodes. Il s’agissait d’une etude prospective transversale de 2 mois allant du 1er fevrier au 30 avril 2020 dans le centre d’hemodialyse de l’hopital regional de Ziguinchor. La recherche de Staphylococcus aureus au niveau nasal a ete effectuee, chez tous les patients hemodialyses chroniques, leurs accompagnants et le personnel soignant. L'ecouvillon a ete introduit dans les narines des patients a une profondeur d’au moins 1 cm en faisant des mouvements rotatoires. Apres une incubation, l’isolement des souches est fait sur milieu selectif de Chapman et les colonies bacteriennes ont ete identifiees par la morphologie, le test enzymatique au peroxyde d’hydrogene, les tests de pathogenicites et le test au latex. Resultats. Sur les 41 ecouvillons realises, 9 avaient isoles le staphylococcus aureus soit une prevalence de 21,95%. Parmi les 9 cas, 5 etaient hemodialyses chroniques. L’âge moyen des depistes etait de 34,66 +/- 12,32ans. La duree moyenne en dialyse des patients etait de 29,44 mois. Trois germes (33,33%) etaient meti-R. Conclusion. Les catheters de dialyse sont des portes d’entree d’infections chez les hemodialyses avec portage nasal de Staphylococcus aureus. Le depistage de ces patients serait important afin de prevenir ce risque. RESUME Objective. Infections are the first cause of morbidity and the second cause of mortality in hemodialysis patients. Nasal carriage of Staphylococcus aureus plays a major role in the occurrence of these infections. The objective of our study was to determine the prevalence of nasal portage in hemodialysis patients and centre staff. Patients and methods. This was a 2-month cross-sectional prospective study from February 1 to April 30, 2020 in the hemodialysis centre of the Ziguinchor regional hospital. The search for Staphylococcus aureus in the nasal area was carried out in all chronic haemodialysis patients, their carers and nursing staff. The swab was introduced into the nostrils of the patients to a depth of at least 1 cm using rotational movements. After incubation, strain isolation was performed on selective Chapman medium and bacterial colonies were identified by morphology, hydrogen peroxide enzyme test, pathogenicity tests and latex test. Results. Of the 41 swabs taken, 9 had isolated Staphylococcus aureus, a prevalence of 21.95%. Of the 9 cases, 5 were chronic hemodialysis cases. The mean age of the detected cases was 34.66 +/- 12.32 years. The average length of time on dialysis was 29.44 months. Three germs (33.33%) were meti-R. Conclusion. Dialysis catheters are gateways for infections in hemodialysis patients with nasal carriage of Staphylococcus aureus. Screening of these patients would be important to prevent this risk." @default.
