Cure8 research brief
The study found higher recorded rates of hidradenitis suppurativa in people with Crohn’s disease and psoriatic arthritis, and a smaller increase in ulcerative colitis, suggesting clinicians should consider asking about HS symptoms in these patient groups.
Clinicians treating Crohn’s disease, psoriatic arthritis, or ulcerative colitis; dermatologists; researchers on immune-mediated skin–gut diseases; adult IBD and psoriatic disease patients noticing recurrent skin problems.
The paper used ICD-coded diagnoses from electronic health records collected between 2006–2026 to estimate baseline prevalence and crude incidence of HS across several spondyloarthritis-related diseases and rheumatoid arthritis for context.
After propensity-score matching (age, sex, BMI, comorbidities) the strongest associations with higher HS incidence were seen for Crohn’s disease and psoriatic arthritis; ulcerative colitis showed a smaller increase. Axial spondyloarthritis and rheumatoid arthritis had lower incidence than matched controls.
The study is epidemiological and identifies associations, not causal mechanisms. The authors call for further research into shared pathophysiology between HS and psoriatic disease.
Retrospective EHR-based study using ICD codes (2006–2026); associations do not prove causation and may be influenced by coding and detection differences. Absolute incidence rates remain low.
