Abstract

BACKGROUND:

Venous thromboembolism (VTE) has been shown to be more frequent in inflammatory bowel disease (IBD) than in the general population in Western studies. However, the actual state of VTE in Asian IBD remains poorly understood.

AIMS:

To reveal the incidence of VTE in IBD patients in Japan.

METHODS:

Eighty-five patients admitted to 3 gastroenterology centers were registered from 2013 to 2018. The incidence of VTE in patients with IBD (n = 42) was prospectively compared to that among patients with other digestive diseases (n = 43). The presence of VTE was surveyed using contrast-enhanced computed tomography and/or ultrasonography at admission and at 1-2 weeks after admission. The patient characteristics and laboratory data of IBD patients with or without VTE were compared to determine the risk factors for VTE.

RESULTS:

The incidence of VTE with IBD was 16.7%, which was significantly more frequent than with other digestive diseases (2.3%; p = 0.0296). In IBD patients, VTE was detected in 6 of 22 patients with ulcerative colitis (27.2%) but in only 1 of 20 patients with Crohn's disease (5.0%). VTE was diagnosed at admission in 4 IBD patients and 2 weeks after admission in 3 IBD patients. The risk factors of VTE in IBD were the presence of an indwelling central venous catheter, a low level of total protein, a low activated partial thromboplastin time, and a high level of fibrinogen degradation products.

CONCLUSION:

VTE was frequently detected in Japanese IBD patients both at and after admission. Adequate screening and prophylaxis for VTE is deemed necessary in IBD.
