Official title
Domestic Environmental Exposure and Progression of Fibrosing Interstitial Lung Diseases: An Exploratory Case-Control Study
Overview
The project titled "Domestic Environmental Exposure and Progression of Progressive or Stable Fibrosing Interstitial Lung Diseases: An Exploratory Case-Control Study" is a Category 3 study involving 60 patients with progressive or stable fibrosing interstitial lung diseases (ILDs). These patients are matched based on the same ILD subtype and their use or non-use of antifibrotic medication. The study aims to thoroughly describe the domestic environment of these patients and investigate the associations between the progression of pulmonary fibrosis and: i) The presence of pollutants and risk factors in the home, including concentrations of nitrogen dioxide, volatile organic compounds, aldehydes, fine particles, mold, dust mite allergens, building defects, and lifestyle habits that increase pollutant exposure. ii) The ambient air quality at the patients' addresses. Occupational exposures will also be considered in the analysis. This project is designed to enhance our understanding of how an unfavorable domestic environment impacts the progression of pulmonary fibrosis and to evaluate the effects of the CMEI (Comprehensive Environmental and Indoor Audit) on patients' ability to manage identified risk factors within their homes, their respiratory health, and their medical diagnosis. The CMEI audit is a preventive measure that could serve as a significant intervention to alter patient behavior, reduce exposure, and improve health outcomes. This project is sponsored by the Environmental Health Laboratories Department, in collaboration with Unit 1018 of the Research Center in Epidemiology and Population Health (CESP), and two investigative centers: Tenon Hospital and Paris Saint-Joseph Hospital.
Interventions
- Other Environmental audit of patient housing
During the home audit of the patient, the Environmental Health Medical Advisor searchs for potential sources of indoor pollution and other housing risk factors (building defects and occupant habits that negatively impact respiratory health). An environmental questionnaire is administered to the patient to gather information about the home environment (ventilation, presence of plants, presence of pets, pests, etc.) and the patient's lifestyle (ventilation habits, use of air fresheners and cleanin
Primary outcome measures
- ILD development linked to exposure to indoor risk factors [Time frame: 6 months]
Secondary outcome measures (2)
- Determine the revision of the ILD diagnosis following the CMEI audit [Time frame: 6 months]
- Assess the impact of EHRA recommendations on patients' respiratory health 6 months after the audit [Time frame: 6 months]
Eligibility criteria
Inclusion criteria
- Patient aged over 18 years
- Patient affected by one of the following interstitial lung diseases (ILDs): Idiopathic Pulmonary Fibrosis (IPF), Nonspecific Interstitial Pneumonia (NSIP), Pneumoconioses, ILDs associated with autoimmune features, Pleuroparenchymal Fibroelastosis (PPFE), Chronic Hypersensitivity Pneumonitis (CHP) whose etiology is not primarily related to the domestic environment, Stage 4 fibrosing sarcoidosis, unclassifiable ILDs.
- ILD patient with progressive fibrosis over the past 12 months (case group)
- ILD patient with non-progressive fibrosis over the past 12 months (control group)
- Patients without reduction in the treatment of interstitial lung disease in the 12 months prior to inclusion, patients without treatment can be included
- Matching "1 progressive fibrosis" / "2 non-progressive fibrosis":
