چکیده
BACKGROUND & AIMS Patients with inflammatory bowel disease (IBD) are at increased risk of a first venous thromboembolism (VTE), yet their risk of recurrent VTE is unknown. We performed a cohort study to determine the risk for recurrent VTE among patients with IBD compared with subjects without IBD. METHODS We assessed 2811 patients with IBD for a history of VTE, recruited from outpatient clinics at 14 referral centers (June 2006-December 2008). Patients with VTE before a diagnosis of IBD or those not confirmed to have VTE, cancer, or a VTE other than deep vein thrombosis or pulmonary embolism, were excluded. Recurrence rates were compared with 1255 prospectively followed patients without IBD that had a first unprovoked VTE (not triggered by trauma, surgery, or pregnancy). The primary end point was symptomatic, objectively confirmed, recurrent VTE after discontinuation of anticoagulation therapy after a first VTE. RESULTS Overall, of 116 IBD patients who had a history of first VTE, 86 were unprovoked. The probability of recurrence 5 years after discontinuation of anticoagulation therapy was higher among patients with IBD than patients without IBD (33.4%; 95% confidence interval [CI]: 21.8-45.0 vs 21.7%; 95% CI: 18.8-24.6; P = .01). After adjustment for potential confounders, IBD was an independent risk factor of recurrence (hazard ratio = 2.5; 95% CI: 1.4-4.2; P = .001). CONCLUSIONS Patients with IBD are at an increased risk of recurrent VTE compared to patients without IBD.

Pulmonary thromboembolism (PTE) is a clinically critical disease, misdiagnosis or delayed diagnosis of which can lead to increased rate of mortality. For prevention of recurrence of PTE, recognition of its risk factors or underlying diseases is of great importance. PTE is common in patients with cancer and has high morbidity and mortality rates. Although cancer is a lethal condition, PTE accele...

Inflammatory bowel disease (IBD) is a disease-specific risk factor for incident and recurrent venous thromboembolism (VTE). The reasons are acquired, multifactorial, and related to prothrombotic aberrations during active disease, although the mechanisms remain incompletely elucidated. VTE represents a potentially life-threatening extraintestinal manifestation of IBD, but the associated morbidit...

Background: Patients with inflammatory bowel disease (IBD) have an increased risk of venous thromboembolisms and recurrent thrombotic disease compared with the general population. Plasma coagulation factor XIII activity has been reported to be decreased in IBD. Two common non-synonymous polymorphisms in the gene encoding coagulation factor XIII, A1 polypeptide F13A1 Val34Leu and F13A1 Pro564Leu...

BACKGROUND Patients with inflammatory bowel disease who develop deep vein thrombosis or pulmonary embolism often have active disease at the time of thromboembolism. We therefore aimed to quantify the risk of venous thromboembolism prospectively during different activity phases of inflammatory bowel disease. METHODS From the General Practice Research Database, we matched patients with prospect...
متن کاملIdentifying risk factors for venous thromboembolism.
Our understanding of risk factors associated with the development of venous thromboembolism (VTE) has increased steadily over the past 20 years. In the 1980s, the development of VTE was conceptualized in the context of the factors in Virchow’s classic triad that he believed led to venous thrombosis. These factors were injury to the endothelium, alteration in blood flow (particularly stasis/immo...
