[New strategies for the etiologic study of interstitial pneumonia: familial registration and sib-pair analysis].
Etiology of idiopathic interstitial pneumonia (IIP) remains unknown. While many studies focused on the analysis of individual patients, available information is limited for the further study. Having experienced a case, 3 of 5 brothers suffered from IIP and 2 of them complicated with lung cancer, intensive familial history taking with chest photos and functional information for fibrotic lung was performed. Among 37 families in which at least 2 members were examined, 14 families (37.8%) had minimum 2 members with fibrotic lungs. Unexpectedly high familial accumulation of fibrotic lung indicates the possibility of multi-gene involvement for the pathogenesis. We need to start group studies to register sib-pairs with fibrotic lungs and systematize the automated genetic analysis for the responsible genes.
