Pulmonary Fibrosis and Telomerase Mutation Study
|ClinicalTrials.gov Identifier: NCT01501578|
Recruitment Status : Completed
First Posted : December 29, 2011
Last Update Posted : February 20, 2018
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|
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.
