Childhood Interstitial Lung Disease

Background Surfactant protein C dysfunction is one of the causes of childhood interstitial lung disease but has not previously been reported in Arabian countries. Case presentation A six-year-old girl had presented at the age of eight months old with bronchiolitis followed by a persistent cough, dyspnea and hypoxaemia. She was found to have gastroesophageal reflux disease, but her symptoms did not resolve despite her therapy being optimised. Further tests, including a chest computed tomographic scan, lung biopsy and genetic testing, confirmed a diagnosis of surfactant protein C dysfunction. Conclusion We report the first case in the Arab region of childhood interstitial lung disease caused by surfactant protein C deficiency.

Heterozygous Carriers

Patients with interstitial lung disease due to surfactant protein C (SFTPC) mutations are rare and not well characterised.We report on all subjects collected over a 15-year period in the kids-lung register with interstitial lung disease and a provenSFTPCmutation. We analysed clinical courses, interventions and outcomes, as well as histopathological and radiological interrelations.17 patients (seven male) were followed over a median of 3 years (range 0.3–19). All patients were heterozygous carriers of autosomal dominantSFTPCmutations. Three mutations (p.L101P, p.E191 K and p.E191*) have not been described before in the context of surfactant protein C deficiency. Patients with alterations in the BRICHOS domain of the protein (amino acids 94–197) presented earlier. At follow-up, one patient was healthy (2 years), six patients were “sick-better” (2.8 years, range 0.8–19), seven patients were “sick-same” (6.5 years, 1.3–15.8) and three patients were “sick-worse” (0.3 years, 0.3–16.9). Radiological findings changed from ground-glass to increasing signs of fibrosis and cyst formation with increasing age. Empiric treatments had variable effects, also in patients with the same genotype.Prospective studies with randomised interventions are urgently needed and can best be performed in the framework of international registers.
