| Abstract |
Purpose
: Interstitial lung disease(ILD) is a rare and poorly characterized disorder in children
with poor prognosis. To understand the ILD in children, we reviewed our experience with 21 patients
who were diagnosed interstitial lung disease during 9-year period at Asan Medical Center
retrospectively.
Methods
: Severity-of-illness score was measured by the Denver protocol. We evaluated underlying
diseases, clinical manifestations, high resolution computed tomography findings, lung pathology
and clinical responses after steroid therapy and prognosis. Fifteen patients were performed
open lung biopsy, but six patients were diagnosed bronchiolitis obliterans by HRCT.
Results
: The median ages at onset of ILD was 1 year 5 month old. Common clinical findings
were tachypnea(90.0%), hypoxemia(90.0%). 14 patients among 15 patients were diagnosed specifically
after open lung biopsy. Interstitial pneumonitis was 6 cases, including 3 nonspecific interstitial
pneumonitis, 2 cases of desquamative interstitial pneumonitis and one usual interstitial
pneumonitis. Other diagnosis included idiopathic pulmonary fibrosis, cytomegalovirus pneumonitis,
diffuse aspiration bronchiolitis, pulmonary lymphangiomatosis, BOOP(bronchiolotis obliterans organizing
pneumonia) and pulmonary histiocytosis. Six patients showed clinical and HRCT findings
consistent with bronchilitis obliterans. Common radiologic findings were mosaic perfusion(12/21),
bronchial wall thickening(9/21). 13 patients among 15 patients with methylprednisolone pulse
therapy showed improvement of clinical symptoms. The severity-of-illness score was improved
significantly after methylprednisolone pulse therapy.
Conclusion
: Pediatric ILD includes heterogeneous disorders. Open lung biopsy was helpful to
make early diagnosis. Severity-of-illness score is a noninvasive and useful measure of disease
progression or response to therapy. Methylprednisolone pulse therapy may be effective to treat
ILD. |
