[Inspiration from diffuse panbronchiolitis].

Diffuse panbronchiolitis is a new respiratory tract disease and was initially found in Japan. Strong association between race-dependent antigens and diffuse panbronchiolitis suggests a genetic predisposition to the disease. 14-member ring and 15-member ring macrolides have been proved to have significant therapeutical effect on diffuse panbronchiolitis. The discovery of diffuse panbronchiolitis and the advent of macrolide therapy for this disease suggests that clinicians should pay more attention to racial difference of some diseases and never overlook any accidental phenomenon in clinical practice.
