Interstitial lung disease in children--a report of four cases

Interstitial lung disease (ILD) is very rare in children. In the majority of cases the aetiology is unknown. Very little is known about the clinical course of this condition in children. Prognosis may be influenced by sex, age of onset of symptoms, radiographic features, presence of right ventricular hypertrophy and histopathology. We report our experience in managing four children with interstitial lung disease. All these children presented in early infancy with cough, respiratory distress, cyanosis and failure to thrive. Three of these children had finger clubbing and right ventricular hypertrophy. All patients received oral steroids. Chloroquine was added in two patients who showed no response. A trial of oral cyclophosphamide was started in one patient who failed with both drugs. One child is oxygen independent while another is on home oxygen therapy. The other two patients eventually died.
