Abstract

BACKGROUND:

A thrombotic etiology for inflammatory bowel disease (IBD) has been proposed as a result of its association with thromboembolic complications, smoking, the oral contraceptive pill, and the response of ulcerative colitis (UC) patients to heparin. We have previously demonstrated an increased prevalence of the Factor V Leiden mutation in UC and wished to investigate the frequency of the recently discovered prothrombin G20210A gene mutation in IBD. The aim of the study was to investigate the hypothesis that the prothrombic state associated with the prothrombin G20210A gene mutation is involved in the etiology of IBD.

PATIENTS AND METHODS:

A prospective cohort study of patients attending the Bristol Royal Infirmary and Gloucestershire Royal Hospital's IBD clinics was performed. Thirty-nine patients with IBD (24 with Crohn's disease and 15 with UC) and 100 historical controls were screened for the presence of the prothrombin gene mutation using a heteroduplex-based polymerase chain reaction technique. None of the patients with IBD had a personal history of thromboembolism, while three of them had a family history.

RESULTS:

No IBD patients had the prothrombin gene mutation compared with four (4%) controls (allelic frequency 2%).

CONCLUSION:

There does not appear to be an association of the prothrombin gene mutation with IBD and therefore it is unlikely to be involved in the etiology of IBD.
