Association between celiac disease and lung disease

Area of Science:

• Pulmonology
• Gastroenterology
• Immunology

Background:

• European reports suggest a link between celiac disease and interstitial lung disease (ILD) of the hypersensitivity pneumonitis type.
• This association requires further investigation in diverse populations.

Purpose of the Study:

• To investigate the association between biopsy-proved celiac disease and interstitial lung disease in North American patients.
• To assess for evidence of airway obstruction in celiac disease patients.

Main Methods:

• A case-control study comparing 18 North American celiac patients with 18 age-, sex-, and smoking-matched controls.
• Assessment included chest roentgenograms, pulmonary function tests (PFTs), and evaluation of respiratory symptoms like cough and asthma.
• Specific PFT parameters measured included FEV1, Vmax 50%, and Vmax 25%.

Main Results:

• No evidence of interstitial lung disease was found in celiac patients via chest roentgenograms or PFTs.
• Celiac patients reported a higher prevalence of asthma or chronic cough compared to controls.
• Objective evidence of airway obstruction was observed in celiac patients, with significant differences in FEV1 and Vmax measurements.

Conclusions:

• The study does not support a link between celiac disease and interstitial lung disease in the studied North American cohort.
• Findings suggest a potential association between celiac disease and airway obstruction.
• Further research is warranted to explore the relationship between celiac disease and non-ILD respiratory conditions.
