Vasculitis & polymyalgia rheumatica
Investigating the concomitance of anti-neutrophil cytoplasmic antibody (ANCA) associated vasculitides and inflammatory bowel disease (IBD)
Authors' conclusion
Objective observation and deductions from this study raise the concern for a possible pathogenic association of ANCA associated vasculitis and inflammatory bowel disease
Study context
- Population
- Patients with AAV (granulomatosis with polyangiitis (GPA), microscopic polyangiitis (MPA) or eosinophilic granulomatosis with polyangiitis (EGPA)) and overlapping IBD (Crohn's disease or ulcerative colitis), 01/01/2020 to 08/03/2023
- Participants
- 39 patients
- Exposure
- GPA vs MPA vs EGPA
- GPAn = 20
- MPAn = 6
- EGPAn = 4
- Outcome
- Order of diagnoses: IBD vs ANCA vasculitis
Main finding
As reported in the abstract
IBD diagnosis preceded the diagnosis of ANCA vasculitis
77.8 %
Observational data: associations, not effects.
