ABSTRACTObjective and designOur prospective study is one of the largest prospective study assessing the role of detailed lung ultrasound features to discriminate the etiological diagnosis of Community acquired pneumonia (CAP) in children.MethodologyWe prospectively analysed patients aged from 1 month to 17 years admitted between March 2018 and April 2020 who were hospitalized for CAP. For all patients included in the study, history, clinical parameters, microbiological data, and lung ultrasound data were collected.Patients were stratified into three main groups (“bacterial”, “viral”, “atypical”) according to the presumed microbial aetiology and lung ultrasound findings evaluated according to the aetiological group.ResultsWe found that some ultrasound findings as size, number and distribution of consolidations, the position and motion of air bronchograms, pleural effusions and distribution of vertical artifacts significantly differ (p < 0.05) in children with bacterial, viral and atypical CAP. Conversely, clinical parameters and laboratory were not able to significantly distinguish between these groups. Chest x-ray, despite being still widely used, was the less useful tool in this discrimination.ConclusionOur study provides a detailed analysis of LUS features able to predict the etiology CAP in children. These findings may help the physicians to better manage a child with CAP and to offer personalized approach, from diagnosis to treatment and follow-up.
