Abstract

SummaryObjectivesa: To evaluate the long‐term outcome of parapneumonic effusions (PPE) in children regarding lung function and exercise tolerance, (b) to investigate the role of bronchial asthma in the outcome of PPE.MethodsThe design of the study included 51 children with PPE, at least 2 years after the initial infection. They were divided in two groups. Group A (38 children) consisted of children with PPE but without asthma prior initial infection. Group B (13 children) included children with PPE and asthma prior infection. Thirty‐six children were taken as healthy controls (group C). All children performed spirometry and a maximal incremental cardiopulmonary exercise test on cycle ergometer.ResultsChildren of both groups (A and B) showed statistically significant lower values in FVC%, FEV1%, and FEV1/FVC compared to controls (group C). Children of group B had also significant lower FEF25–75% values compared to controls. Children of group B had significant lower FEV1/FVC values compared to group A. All children of the three groups showed no differences in maximal exercise capacity (VO2max). Children of group A had higher respiratory equivalent to oxygen (VE/VO2) during exercise compared to healthy subjects.ConclusionsThere are small effects on lung function and exercise capacity in the long‐term, among children with PPE, but of no clinical importance. Pre‐existing bronchial asthma doesn't influence the outcome significantly. Pediatr Pulmonol. 2015; 50:615–620. © 2014 Wiley Periodicals, Inc.
