Infants and Young Children with Children's Interstitial Lung Disease

Though interstitial lung disease (ILD) can occur at any age in children, disorders more common in infancy and young children have received increased attention as an important group that is disproportionally affected, linked to lung development and lung injury, and represents disorders not seen in adult ILD. Identifying those children with potential children's ILD (chILD) and establishing a specific chILD diagnosis has evolved and is critical for pediatric pulmonologists, neonatologists, radiologists, and pathologists to recognize. Specific disorders more common in infancy include diffuse developmental disorders, growth abnormalities, pulmonary interstitial glycogenosis, neuroendocrine cell hyperplasia of infancy, and surfactant mutation dysfunction mutations. The presentation, evaluation, treatment, and clinical course are discussed for each of these specific disorders and other categories less common in infants and young children are briefly mentioned.

Childhood interstitial lung diseases in immunocompetent children in Australia and New Zealand: a decade’s experience

Abstract Background Childhood interstitial lung disease (chILD) represents a rare heterogeneous group of respiratory disorders. In the absence of randomized controlled clinical trials, global collaborations have utilized case series with an aim to standardising approaches to diagnosis and management. Australasian data are lacking. The aim of this study was to calculate prevalence and report the experience of chILD in Australasia over a decade. Methods Paediatric pulmonologists in Australia and New Zealand involved in the care of patients aged 0–18 years with chILD completed a questionnaire on demographics, clinical features and outcomes, over a 10 year period. These data, together with data from the 2 reference genetics laboratories, were used to calculate prevalence. Results One hundred fifteen cases were identified equating to a period prevalence (range) of 1.5 (0.8–2.1) cases/million for children aged 0–18years. Clinical data were provided on 106 patients: the <2 year group comprised 66 children, median age (range) 0.50 years (0.01–1.92); the ≥2 year group comprised 40 children, median age 8.2 years (2.0–18.0). Management approach was heterogeneous. Overall, 79% of patients had a good clinical outcome. Mortality rate was 7% in the study population. Conclusion chILD is rare in Australasia. This study demonstrates variation in the investigations and management of chILD cases across Australasia, however the general outcome is favorable. Further international collaboration will help finesse the understanding of these disorders
