Hidradenitis Suppurativa More Prevalent Among Patients With Crohn Disease
Skin disease (hidradenitis suppurativa) may be more common in people with IBD—particularly Crohn disease—and could be linked with more severe intestinal complications. Awareness can prompt coordinated care between gastroenterology and dermatology.
Adults with Crohn disease or ulcerative colitis, clinicians caring for IBD patients, dermatologists, and researchers studying shared inflammatory mechanisms between skin and gut disease.
What To Know
Hidradenitis suppurativa (HS) appears more common in people with IBD—especially Crohn disease—and was associated with markers of more severe intestinal disease in a retrospective TriNetX cohort presented at AIBD 2024.
The study compared prevalence and clinical outcomes (including colectomy, bowel obstruction, perforation, hospitalizations, and mortality) between patients with IBD with and without HS and between HS patients with CD versus UC.
The report found higher prevalence of HS in CD than UC and that IBD patients with HS had higher rates of bowel obstruction; several complications (fistula, abscess, strictures/obstruction, ulcers) were more common in CD patients with HS than in UC patients with HS.
The authors suggest HS may signal shared inflammatory mechanisms and greater disease activity, and they call for further research. This is a conference abstract / retrospective database analysis rather than a randomized trial; it can identify associations but not prove cause.
If you have both IBD and skin disease, discuss this with your gastroenterologist and dermatologist so they can consider coordinated care and appropriate monitoring.
This report summarizes a retrospective TriNetX database analysis presented as a conference abstract (AIBD 2024). Such studies can show associations but have limitations (coding accuracy, unmeasured confounding). The findings suggest a need for further prospective research before changing treatment.
