ARTICLE HIGHLIGHTS
Research background
Venous thromboembolism (VTE) is a major complication in patients with inflammatory bowel disease (IBD). However, it is often underappreciated among physicians and patients. Furthermore, limited VTE risk stratification tools are available for personalized thromboprophylaxis.
Research motivation
A large IBD patient cohort is available from the UK Biobank (UKB). Its long-term clinical follow-up data and genome-wide genetic data provide a rare and efficient opportunity to address these two major challenges.
Research objectives
To estimate the prevalence of VTE complications among IBD patients and assess the performance of known and novel genetic predictors of VTE risk stratification in these patients.
Research methods
We retrospectively followed the incident VTE complication among 8465 IBD patients in the UKB. The associations of VTE with factor V leiden (FVL) mutation in the F5 gene, G20210A prothrombin gene mutation (PGM) in the F2 gene, and polygenic score (PGS) were tested using Cox hazards regression analysis, adjusting for age at IBD diagnosis, gender, and genetic background (top 10 principal components). The performance of genetic risk factors for discriminating VTE complications was estimated using the area under the receiver operating characteristic curve (AUC).
Research results
The overall prevalence of VTE complication after an IBD diagnosis was 4.70%. This prevalence was comparable to that of cancer patients (4.66%) who are well-known at increased risk for VTE. A novel genetic predictor (PGS) was significantly associated with VTE risk and was independent of known genetic predictors (FVL/PGM). The AUC of differentiating VTE complication was significantly higher for PGS [0.68, 95% confidence interval (CI): 0.66-0.71] than that of FVL/PGM (0.64, 95%CI: 0.61-0.67) and was highest by combining these two genetic predictors (0.69, 95%CI: 0.66-0.71).
Research conclusions
VTE complication is common in IBD patients and is similar to that of cancer patients. Newly developed PGS provides a more informative VTE risk stratification tool than known mutations (FVL/PGM).
Research perspectives
Findings from this large study of IBD patients have potential clinical utilities. It not only highlights the significance of VTE complications in IBD patients, but also provides an informative VTE risk assessment tool for developing personalized thromboprophylaxis strategies.
