Vasculitis & polymyalgia rheumatica
Association between large vessel vasculitis and inflammatory bowel disease: a case-control study
An erratum to this article was published (Rheumatology (Oxford), 8 Jan 2026 ↗)
Authors' conclusion
This study identifies specific clinical and imaging characteristics of LVV-IBD patients, in particular a more severe vascular presentation of GCA-IBD patients compared with iGCA patients.
Study context
- Population
- Patients with large vessel vasculitis (LVV) (Takayasu arteritis or GCA) and IBD from European countries; controls with isolated LVV
- Participants
- 39 / 93 / 12 / 52
- Comparison
- LVV with IBD vs isolated LVV
- TA-IBDn = 39
- Isolated TA (iTA)n = 93reference
- GCA-IBDn = 12
- Isolated GCA (iGCA)n = 52reference
- Outcome
- Clinical and imaging characteristics of LVV-IBD vs isolated LVV: age at TA diagnosis and upper limb claudication (TA-IBD vs iTA); arterial thickening or stenosis (GCA-IBD vs iGCA)
