Cure8 research brief
People with UC face higher cardiovascular risk; this study links a specific ITGA4 genetic variant (rs1143674 CC) with subclinical atherosclerosis in UC patients over 40, which could help identify higher-risk individuals for earlier screening.
Patients with ulcerative colitis (particularly age >40), gastroenterologists, cardiologists involved in IBD care, and researchers in IBD genetics and cardiovascular complications.
This study examined whether the ITGA4 rs1143674 genetic variant is linked with subclinical atherosclerosis in people with ulcerative colitis (UC). It used ultrasound of carotid and femoral arteries and genotyping in a cross-sectional cohort of UC patients and healthy controls.
The authors report that in UC patients aged >40, the homozygous CC genotype was more common among those with subclinical atherosclerosis and that age ≥40, CC genotype, and continuous UC course were independent predictors in multivariable analysis.
The paper proposes a prognostic model combining age, UC disease course, and ITGA4 genotype that showed acceptable discrimination (AUC reported). The study is single-center and cross-sectional, so it identifies associations rather than proving causation.
If you have UC and are interested in cardiovascular risk, this research suggests genetic factors (ITGA4 rs1143674 CC) might help identify higher-risk subgroups over age 40, but the work needs replication and prospective validation before changing clinical practice.
Cross-sectional design shows association only; single-center cohort and the prognostic model need external replication and prospective validation. The article reports ultrasound and genotyping methods but does not establish clinical benefit of genotype-guided screening.

This research suggests genetic risk scores could help identify people with IBD who are more likely to have severe disease, which might eventually inform earlier monitoring or treatment decisions. It’s a step toward more...
