Abstract Summary A retrospective cohort study of 113,729 IBD patients with low cardiovascular (CV) risk using the US National TriNetX database. Anti-TNF and anti-integrin therapies were linked to reduced major adverse cardiovascular events (MACE), while JAK inhibitors showed no increased risk. Background Due to underlying chronic inflammation, inflammatory bowel disease (IBD) is associated with an increased risk of major adverse cardiovascular events (MACE). There is limited data on the role of cardiovascular (CV) risk factors and IBD medications on MACE. We aim to determine the association between MACE and IBD medications in a large national cohort of IBD patients with low baseline CV risk. Methods We conducted a retrospective cohort study between January 1, 2015—November 15, 2023 using the TriNetX database. Using logistic regression analysis, IBD patients exposed to biologics and small molecules were assessed for outcomes of individual and composite MACE [myocardial infarction (MI), ischemic stroke, percutaneous coronary intervention (PCI)/coronary artery bypass graft (CABG)]. Outcomes were adjusted for demographics, non-advanced IBD therapies, statin use, CV risk factors, and prior history of coronary artery disease (CAD). Results We identified 113,729 IBD patients with an average age of 42 years and low prevalence of CV risk factors (5-6%). Anti-TNF therapy was associated with a statistically significant decreased risk of composite MACE [adjusted OR (aOR) 0.795, 95% CI 0.670-0.930, p = 0.005] and PCI/CABG [aOR 0.56, 95% CI 0.274-0.562, p = 0.002] and anti-integrin therapy was associated with a decreased risk of composite MACE [aOR 0.76, 95% CI 0.580-0.980, p = 0.035]. Anti-IL12/23 and JAK inhibitors showed no increased risk of MACE. Conclusion In a cohort of young IBD patients with low CV risk, use of anti-TNF and anti-integrins is associated with a decreased risk of MACE and there was no increased risk of MACE with JAK inhibitors.

ObjectiveNeuroinflammatory adverse events have been observed among new users of tumor necrosis factor (TNF) inhibitors. No studies to date have compared the real‐world risk of TNFs with other new users of biologic or targeted synthetic disease‐modifying antirheumatic drugs (b/tsDMARDs). The objective of this study is to describe the risk of neuroinflammatory disease after initiation b/tsDMARDs.MethodsThis new user comparative effectiveness cohort study used a large US‐based electronic health records database to describe the unadjusted incidence of neuroinflammatory adverse events over a 3‐year period. The cohort included patients with rheumatoid arthritis, psoriasis, psoriatic arthritis, ankylosing spondylitis, Crohn's disease, or ulcerative colitis initiating treatment with a TNF inhibitor (n = 93,661) or other b/tsDMARD (n = 38,354).ResultsAmong 132,015 patients included in the analysis, the most common first biologic agent was a TNF inhibitor; the unadjusted incidence of neuroinflammatory events was numerically lower among new users of TNF inhibitors (incidence 1.34 per 1,000 patient‐years) as compared with the combined non‐TNF group (1.69 per 1,000 patient‐years). There was no significant association between TNF exposure and neuroinflammatory events as compared with the combined non‐TNF b/tsDMARDs overall (hazard ratio 1.01; 95% confidence interval 0.75–1.36) and within each disease group.ConclusionThe overall risk of neuroinflammatory events among new users of TNF inhibitors did not differ substantially as compared with new users of other b/tsDMARDs. Meta‐analyses of randomized trials should be conducted to corroborate these findings, which may be affected by channeling bias.
