An interventional study of Blood sample in Idiopathic Pulmonary Fibrosis, Pulmonary Disease and Pulmonary Medicine, sponsored by Assistance Publique - Hôpitaux de Paris. Recruiting at 16 sites in France. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2021-10-25.

Idiopathic Pulmonary Fibrosis(IPF) is the most common idiopathic interstitial lung disease whose cause is unknown. With age and gender, socio-economic factors are the most influential indicators of health. At present there is very little data on socio-economic factors in the IPF. The investigators hypothesize that a lower socio-economic level and / or exposure to various air pollutants may influence the IPF's natural history, including the severity of diagnosis and prognosis of the IPF. The investigators also hypothesize that the deleterious effect of air pollutants is modulated by individual susceptibility (shorter telomeres) and that this effect is related to oxidative stress and shortening of telomeres.
Idiopathic Pulmonary Fibrosis is the most common idiopathic interstitial lung disease whose cause is unknown. However, it remains a rare disease, there is an incidence of approximately 4400 new patients per year in France. It is a serious disease with few therapeutic options and a median survival after diagnosis around 36 months. It is also responsible for high morbidity, with a marked deterioration in quality of life (dyspnea, cough, fatigue and anxiodepressive disorders) and significant functional impairment (respiratory failure) With age and gender, socio-economic factors are the most influential indicators of health.

Exclusion Criteria:
Blood sample were performed during the study for all patients.
Diagnostic Test: Blood sample
Blood sample performed at the inclusion and during the follow-up.
Determine if the household income is associated with the severity of the IPF at inclusion
Patients will be classified into three groups: "lower" standard of living, "average" level and "higher" level. These groups are respectively defined by wages : less than 1000 euros, greater than or equal to 1000 euros and less than 4000 euros, and greater than or equal to 4000 euros. The severity of the IPF at baseline will be defined by the respiratory functional impact: a forced vital capacity (FVC) of less than 50% and / or a Carbon monoxide diffusion capacity of less than 30%.

Time frame: 24 months
Determine if the deleterious effect of air pollutants on the decline of respiratory function is dependent on the size of the telomeres
Collection of data about deleterious effect of air pollutants on the decline of respiratory function and about the length of telomers calculated with T/S ratio. Blood samples will be performed for analysis of biomarkers and oxidative stress in IPF, measurement of telomere length, MUC5B, TOLLIP and GSTT1 polymorphisms.
