Abstract:
The clinical features, imaging findings and pathological manifestations of children diagnosed with acute interstitial pneumonia (AIP) in the Department of Respiratory, Beijing Children′s Hospital, Capital Medical University from January 2016 to December 2017 were retrospectively analyzed.One patient was a girl aged 8 years and 4 months, and the other patient was a boy aged 1 year and 11 months.Both of them had cough and tachypnea for 20 days with transient afebrile.They were diagnosed as Mycoplasma pneumonia and viral pneumonia, respectively, in other hospitals, but the treatment effect was poor.The physical examination results at admission suggested tachypnea, three depression sign (+ ), cyanosis of lips and fingers, no acropachia, and no rales.No abnormality in cardio abdominal and nervous system was detected.Both patients had hypoxemia.The partial pressure of carbon dioxide was normal.The investigations of pathogen were negative.Autoantibody and antineutrophil cytoplasmic antibodies were negative.High resolution CT (HRCT) showed reduced light transmittance of both lungs (especially the lower lung), diffuse bilateral ground glass opacities, consolidation, and traction associated bronchiectasis.The pulmonary histopathology showed di-ffuse alveolar damage, thickened alveolar septum and fibrous tissue in the alveolar cavity.The hyaline membrane was observed in the girl patient.Both patients were treated with corticosteroid.The girl patient had nasal cannula oxygenation, while the boy patient received nasal continuous positive airway pressure (NCPAP) support.They were followed up with improvement.The course of corticosteroid was taped for 8 months and 1 year in the girl patient and boy patient, respectively.After treatment, lung lesions were basically absorbed.
