Prolonged neonatal jaundice in RegionÖrebro County : - a comparison of two management strategies

Perpåls, Adina January 2022 (has links)
Introduction: Prolonged neonatal jaundice is defined as persistent jaundice at two-three weeksof age. Prolonged neonatal jaundice is usually harmless but one in 2500 newborns have jaundicedue to cholestasis, why further investigation must be made. Region Örebro County introduced anew referral routine for prolonged neonatal jaundice 2021-02-12 that allows for follow up inLindesberg or Karlskoga instead of Örebro alone, and only three variables need to be mentionedfor the referrals to be considered complete, contrary to previous six. Aim: To compare Region Örebro County’s current and previous referral routine for prolongedneonatal jaundice in regard to compliance and complete referrals. Methods: A chart review was performed of all children born in Region Örebro County between2021-02-12 and 2022-02-01 with either sampled bilirubin and/or diagnosis code p.55, p.57-59. Results: A statistically significant difference was observed between the routines regarding stoolcolour (p=0.004), general condition (p<0.001), complete referrals (p<0.001) and length ofinvestigation (p<0.001). Significantly fewer patients were lost during investigation (p<0.002) orhad no feedback on their test results (p<0.011). Two cases of cholestasis were found. The meanvalue of conjugated bilirubin was higher in patients who saw a doctor. Few children werereferred from Lindesberg or Karlskoga. Conclusion: The current routine had more complete referrals, shorter investigation times andless absence of feedback as well as fewer patients lost during investigation. Sick patients wereidentified before getting critically ill. Shifting the entire investigation to primary care andimplementing stool charts could possibly improve the routine further.

L'effet de l'âge gestationnel sur l'incidence, l'étiologie, le traitement et le pronostic de la cholestase néonatale

El Raichani, Nadine 08 1900 (has links)
Cadre conceptuel et problématique : La cholestase hépatique est une pathologie à large éventail d’étiologies, affectant fréquemment les nouveau-nés. Un diagnostic approprié est essentiel pour la prise en charge clinique, le choix des traitements et l’amélioration du pronostic. Alors que les prématurés ont un risque accru de développement de la cholestase, les algorithmes de traitement ne proposent qu’une prise en charge unique, quel que soit l’âge gestationnel (AG) du patient. Objectif : Déterminer si le profil clinique, la prise en charge et le pronostic de la cholestase néonatale diffèrent selon l’AG. Méthodologie : Une étude de cohorte rétrospective de nouveau-nés atteints de cholestase et admis en néonatologie au CHU Sainte Justine entre janvier 2014 et décembre 2017 a été menée. La cholestase était définie par au moins deux valeurs consécutives de bilirubine conjuguée ≥ 34 μmol/L. La cohorte a été stratifiée en deux groupes d’AG : les extrêmes et les grands prématurés (< 32 semaines AG) et les prématurés modérés ou tardifs et naissances à terme (≥ 32 semaines AG). Résultats : 125 nouveau-nés sur 3 277 ont développé une cholestase. L’incidence globale était de 4% ; cette incidence était 5 fois plus élevée chez les nouveau-nés < 32 semaines d’AG comparativement aux ≥ 32 semaines d’AG. La cholestase était associée à une nutrition parentérale chez 91% des patients avec AG < 32 semaines et seulement 40% des patients avec AG ≥ 32 semaines (p < 0,01). Alors que l'acide ursodésoxycholique était plus prescrit aux nouveau-nés ≥ 32 semaines AG, les émulsions lipidiques à base d'huile de poisson étaient plus administrées aux nouveau-nés < 32 semaines AG, parmi les patients recevant une nutrition parentérale. Conclusion : La cholestase néonatale est associée à deux profils cliniques différents, basés sur l'AG. Nous recommandons que les tests diagnostics et la prise en charge clinique de la cholestase soient adaptés à l'AG. Une nouvelle approche pour l'évaluation d'un nourrisson atteint d'hyperbilirubinémie conjuguée est proposée. / Background and Aims: Cholestasis is a frequent neonatal disease that has a wide range of etiologies. Appropriate diagnosis is essential to clinical management, treatment choices and improvement of outcomes. Most references discuss neonatal cholestasis as one entity. The goal of this study was to determine if the clinical profile, management and outcome of cholestasis differ according to gestational age (GA). Methods: Medical records of infants with cholestasis in the division of neonatology at CHU Sainte Justine, between January 2014 and December 2017, were retrospectively reviewed. Cholestasis was defined as two or more consecutive conjugated bilirubin values ≥ 34μmol/L. The cohort was stratified into two groups: extremely to very preterm (< 32 weeks GA) and moderate to late preterm and term (≥ 32 weeks GA). Results: 125 of 3,277 patients developed cholestasis. Overall incidence of cholestasis was 4%. Incidence was 5 times higher in neonates < 32 weeks GA compared to neonates ≥ 32 weeks GA. Cholestasis was associated with parenteral nutrition in 91% of patients with GA < 32 weeks and 40% of patients with GA ≥ 32 weeks (p < 0.01). While ursodiol treatment was prescribed more to cholestatic neonates ≥ 32 weeks GA, fish oil lipid was administered more to neonates < 32 weeks GA, among patients receiving parenteral nutrition. Conclusions: Neonatal cholestasis was associated with two different clinical profiles based on GA. We recommend diagnostic tests and clinical management of neonatal cholestasis be adapted to GA. A GA-based approach to the evaluation of an infant with conjugated hyperbilirubinemia is proposed.
