2008 National Survey of Idiopathic Interstitial Pneumonia in Korea

Abstract

BACKGROUND
There is limited data on the epidemiology and relative frequency of idiopathic interstitial pneumonia (IIP) worldwide. This survey was performed to assess the epidemiology and relative frequency of IIP in Korea.
METHODS
The patients with IIP and who were confirmed by lung biopsy, except those patients with idiopathic pulmonary fibrosis, (IPF) over a 5 year period (from Jan. 1st, 2003 to Dec. 31st, 2007) were registered by a web-base questionnaire.
RESULTS
A total of 3,156 cases were registered, but 970 cases were excluded due to duplicative registration, inadequate data and the unmet ATS/ERS diagnostic criteria. A total of 2,186 cases were analyzed. The male to female ratio was about 2 : 1 and their mean age was 65 (range: 11~94). The most frequent disease was IPF (77.1%), followed in decreasing order by nonspecific interstitial pneumonia (NSIP) (11.9%), cryptogenic organizing pneumonia (COP) (8.5%), acute interstitial pneumonia (AIP) (1.1%), desquamative interstitial pneumonia (DIP) (0.9%), respiratory bronchiolitis-interstitial lung disease (RB-ILD) (0.4%) and lymphocytic interstitial pneumonia (LIP) (0.1%). The mean age of the patients with IPF, NSIP and COP was 67.8, 57.1 and 57.7 years old, respectively. The most frequent symptom was dyspnea on exertion (69%) followed by coughing (61%) and sputum (33%) for the whole population. The three year survival rate was 62% for the patients with IPF and the five year survival rate was 85% in both the NSIP and COP patients.
CONCLUSION
This survey provides helpful information for the management of IIP and to produce management guidelines for this illness in Korea.
