Frequency of hepato-pulmonary syndrome in pediatric transplanted patients in a high complexity hospital in Medellín, Colombia

Abstract

Introduction. Hepatopulmonary syndrome (HPS) is a serious complication in patients with chronic liver disease and/or portal hypertension. The frequency described in adults is between 4% and 47%. In pediatrics, reports are also highly variable and range from 3% to 40%, with the real incidence not clear yet. The objective of this study is to know the frequency of HPS in our population through an active search for HPS in pre-liver transplant studies in clinical records. Methodology. This is a 5-year retrospective study, in a reference hospital in Colombia, that included children under 15 years of age with a first liver transplant. Results. In 24 patients, the information was available, demographic variables were analyzed, and HPS was confirmed in 18 patients (75%), finding mild and moderate severity in 33% and 44%, respectively. In this group, cirrhosis with complications due to portal hypertension was the most frequent indication for transplantation and biliary atresia was the main etiology in 61%. Conclusion. HPS in our population was found with a high frequency, higher than is described in the literature, leading to the recommendation of an active search, with the aim of providing comprehensive and timely management.
