Lung disease more common with ulcerative colitis than Crohn's disease

A study published in Crohn's & Colitis 360 on July 24 reveals that interstitial lung disease (ILD) is more frequently linked to ulcerative colitis (UC) than to Crohn's disease (CD). Researchers from the University of Florida College of Medicine in Jacksonville analyzed data from 8,865 patients with inflammatory bowel disease (IBD) treated at two major healthcare centers in the southeastern United States between 2012 and 2022.

The findings indicate that 4.6% of these patients suffered from both IBD and ILD. The prevalence of ILD was notably higher in UC patients compared to CD patients. Although demographic factors were similar between UC-ILD and CD-ILD groups, minority patients with IBD-ILD had a higher rate of comorbidities compared to their White counterparts.

Furthermore, individuals with IBD-ILD were significantly older, had more emergency department visits and hospitalizations, relied more on steroids, and were less likely to receive mesalamine medication compared to those with IBD alone. Given the increased healthcare burden associated with IBD-ILD, early diagnosis and screening of ILD should be prioritized in all IBD patients, particularly UC patients, as suggested by the authors.
