Brief Summary:

This study is an observational and retrospective study of patients with pulmonary fibrosis associated or not with telomerase mutation.

The purpose of this study is to describe in detail the cases with telomerase mutation in terms of features on CT scan, respiratory function and evolution, in comparison to control subjects with idiopathic pulmonary fibrosis and no telomerase mutation identified or family history.


Condition or disease
Pulmonary Fibrosis

Detailed Description:

Two "control" subjects will be enrolled for one subject with telomerase mutation.

The data are all the results of investigations conducted for the diagnosis of idiopathic pulmonary fibrosis and during routine follow up of patients.

The CT scans will reviewed centrally to homogenize the description.


Study Type : Observational
Actual Enrollment : 81 participants
Observational Model: Case-Control
Time Perspective: Retrospective
Official Title: Phenotype of Pulmonary Fibrosis Associated With a Mutation of Telomerase
Study Start Date : December 2011
Actual Primary Completion Date : June 2012
Actual Study Completion Date : December 2015

Group/Cohort
telomerase mutation
Patients with interstitial lung disease and telomerase mutation
control
Patients with idiopathic pulmonary fibrosis and without telomerase mutation



Primary Outcome Measures :
  1. Description of imaging pattern [ Time Frame: at baseline only ]
    Description of imaging pattern on representative CT scan at diagnosis.


Secondary Outcome Measures :
  1. Pathology of the lung [ Time Frame: at baseline only ]
    description of pathological pattern

  2. Pulmonary function tests [ Time Frame: from diagnosis to last follow-up, for an average of one year ]
    analyze the respiratory function


Biospecimen Retention:   Samples With DNA
one blood sample is collected for genetic analysis of telomerase mutation
