Primary Outcome Measures

Name	Time	Method
The predictive value of the Telomere length, TERT, TERC, MUC5B, MUC4, TOLLIP, SFTPA2 polymorphisms/mutations for the development, clinical course, classification and response to drugs of idiopathic pulmonary pneumonias.

Secondary Outcome Measures

Name	Time	Method
The association of the Telomere length, TERT, TERC, MUC5B, MUC4, TOLLIP, SFTPA2 polymorphisms/mutations for the development, clinical course, classification and response to drugs of idiopathic pulmonary pneumonias. Bank the immortalized lymphocytes for the future studies that investigate the association of the development of IIPs with the novel genetic biomarkers.
