Background/Purpose: The association of large vessel vasculitis (LVV), whether Takayasu arteritis (TA) or giant cell arteritis (GCA), with inflammatory bowel disease (IBD) is a rare and challenging condition. The prevalence of LVV in IBD cohorts is less than 1%, but the prevalence of IBD can be as high as 15.4% in TA cohorts, and population-based studies confirmed this association. We aimed to describe the characteristics and outcome of LVV-IBD patients, with a focus on the therapeutic management.
Methods: We performed an observational, multicenter, retrospective case-control study in Western Europe countries (France, Italy, Spain, Germany, Belgium). Cases were adults or children with both LVV and IBD (LVV-IBD), whereas controls had isolated TA (iTA) or GCA (iGCA).
Results: Fifty-one LVV-IBD patients were included, including 39 TA-IBD and 12 GCA-IBD patients, and compared with 93 iTA and 52 iGCA. LVV-IBD patients were mostly females (75% in TA-IBD and 72% in GCA-IBD). Crohn's disease was more common in TA-IBD (67%), while ulcerative colitis was more common in GCA-IBD (58%). LVV occurred after IBD in most cases (56% in TA-IBD and 75% in GCA-IBD), with a median interval of 1 year in TA-IBD and 8.6 years in GCA-IBD, and were diagnosed concomitantly in 16%. Location, behaviour and complications of IBD were similar to previously reported IBD cohorts.
Compared to iTA patients, TA-IBD patients were significantly younger at TA diagnosis (27 vs. 37 years, p < 0.001) and had more upper limb claudication (36 vs 12%, p=0.006). The number of affected arterial segments was lower in TA-IBD (3 vs. 4 segments, p=0.015) and carotid artery involvement was less common in TA-IBD patients than in iTA patients (50 vs. 75% respectively, p=0.005).
Compared to iGCA patients, GCA-IBD patients had more arthralgia (50 vs 15%, p=0.017) and vascular murmur (25 vs 0%, p=0.016). GCA-IBD patients had more arterial thickening or stenosis than controls (75 vs. 30% respectively, p=0.044).
LVV occurred in IBD patients while on therapy in 77% (86% for TA-IBD and 56% for GCA-IBD), including oral glucocorticoids (GCs) in 36%, azathioprine (AZA) in 25%, or TNF-a blockers in 33% of TA-IBD.
LVV-IBD were treated with GCs in 91%, methotrexate in 43%, AZA in 17% or cyclophosphamide in 3.2%. Biologics were used in 24%, including mainly TNF-a blockers in TA-IBD patients (33%). AZA was used more frequently in TA-IBD patients than in iTA, with the latter mainly receiving methotrexate.
The presence of IBD did not influence the vasculitis relapse rate (OR 1.40 [0.39-5.10] for GCA and OR 0.72 [0.34-1.51] for TA). Aortic insufficiency in GCA patients (OR 8.36, 95% CI 1.35-51.66), and ascendent aorta involvement (OR 2.35, 95% CI 1.20-4.60) and the presence of general symptoms (HR 2.02, 95% CI 1.01-4.03) in TA patients were identified as independent vasculitis relapse risk factors.
Conclusion: This large case-control study identifies new clinical, imaging and outcome features in LVV-IBD. Vascular involvement seems to be less severe in TA-IBD than in iTA, while it seems to be the opposite in GCA-IBD. LVV-IBD occurred despite ongoing treatment in 77%, including AZA and/or TNF-a blockers in almost half of the cases.
