Brief Summary:
A case-control study to investigate whether job exposures are an under-recognized cause of idiopathic pulmonary fibrosis (IPF) using an interview to collect information about previous jobs and a blood test to investigate genetic susceptibility.

Condition or disease Intervention/treatment
IPF Idiopathic Pulmonary Fibrosis Other: Computer-assisted telephone interview Genetic: Genetic analysis

Detailed Description:
Idiopathic pulmonary fibrosis (IPF) is a scarring lung disease. It damages the air sacs that allow oxygen to be transferred into the blood and transported to vital organs. These changes make people with IPF cough and feel short of breath. It not known what causes the damage. People who get IPF are usually older than 40; it's a very serious illness that cannot be cured and gets worse over time. Statistics show that IPF is becoming more common in the UK but it's not known why. It can be difficult for doctors to tell if someone has IPF or another disease called asbestosis.

Groups and Cohorts

Group/Cohort Intervention/treatment
Case
Males with an incident diagnosis of IPF made between the 1st of February 2017 and the 5th of October 2019.
 Other: Computer-assisted telephone interview
Occupational history

Genetic: Genetic analysis
To include analysis of known susceptibility markers
Controls
Males with an incident hospital outpatient attendance between the 1st of February 2017 and the 5th of October 2019 who do not have a diagnosis of IPF. At each participating centre a control clinic is randomly selected from all control clinics that the research team is able to recruit from; this clinic is the source clinic for controls for the duration of the study.
 Other: Computer-assisted telephone interview
Occupational history

Genetic: Genetic analysis
To include analysis of known susceptibility markers


Outcome Measures
Go to 
Top of Page Study Description Study Design Groups and Cohorts Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Association between asbestos exposure and IPF [ Time Frame: 2 years ]
    estimated using logistic regression for any vs no asbestos exposure and adjusting for age and smoking status


Secondary Outcome Measures :
  1. Dose-response relationship between asbestos exposure and IPF [ Time Frame: 2 years ]
    estimated using logistic regression for categories of cumulative exposure and adjusting for age and smoking status

  2. Gene-environment interaction (for MUC5B rs35705950 and asbestos exposure) odds ratio. [ Time Frame: 2 years ]
    MUC5B rs35705950 and asbestos exposure odds ratio.
