Abstract
Background
IBD patients are at increased risk of coronary artery disease in the absence of traditional risk factors. However, the disease-related risk factors remain poorly understood although increased inflammation seems to increase cardiovascular disease risk in IBD. Thrombocytes are involved in the pathogenesis of coronary artery disease, and a subset of IBD patients have reactive thrombocytosis.
Aim
The aim of our study was to investigate the effect of persistent reactive thrombocytosis on the development of coronary artery disease in IBD.
Methods
We evaluated a retrospective cohort of 2525 IBD patients who were evaluated at the Henry Ford hospital from 2000 to 2004. We performed a case–control study comparing patients with persistent thrombocytosis and patients without persistent thrombocytosis. Cases (n = 36) and controls (n = 72) were matched for age and gender. Coronary artery disease incidence was compared between the two groups.
Results
Cases (n = 36) and controls (n = 72) were matched for age and gender. Cases and controls were similar in age at onset of IBD (41.5 vs. 35.5, p value 0.11) and smoking status (33.3 vs. 27.8 %, p value 0.66). Persistent thrombocytosis was less common among Caucasian patients (44.44 vs. 62.5 %, p value 0.09) and more common in patients who had exposure to steroids during the study follow-up period. Coronary artery disease occurred in 13 (36.1 %) patients with persistent thrombocytosis compared to only seven (9.7 %) patients in the control group.
Conclusions
Persistent reactive thrombocytosis among IBD patients is associated with increased risk of coronary artery disease. Further studies should characterize the clinical and molecular associations of this phenomenon and determine appropriate therapeutic measures.
