In most European countries rare orphan diseases such as pediatric interstitial lung diseases (ILDs) are still underdiagnosed.Objective: To investigate/ describe pediatric ILDs in a tertiary university hospital in North Italy.Methods: we included 18 children admitted to the Pediatric Department of the Padova University Hospital from 2003 until 2012 with a diagnosis of ILD. Children were identified retrospectively through clinical charts and clinical, radiological, functional, pathological, biological and genetic data were collected.Results: Data were available for x children presenting with ILD.Median age at diagnosis was 5.5 years [1-16 years], and the sex ratio was 0.5 male/female.Radiologic, laboratory histology and genetics led to the following diagnosis: Bronchiolitis obliterans organizing pneumonia (BOOP), surfactant protein B mutation and viral induced interstitial lung disease were the most common diagnoses. At high resolution CT-scan, 14/18 children showed in 16 % a Honey comb pattern, in 16 %, a reticular picture, in 16% a nodular picture, and in 52% ground glass opacity.Chronic cough and wheezing episode were the most common symptoms reported.Conclusion: In Italy, pediatric ILD is still under estimated. A national database, such as the German, UK or France registry, and national guidelines for diagnosis and possible therapies are necessary to allow physicians and patients to have a more adequate diagnosis and follow-up.
