Insights
In patients with inflammatory bowel disease (IBD), a family history of thrombosis is a significant predictor of developing blood clots. This finding is crucial for risk assessment in IBD patients, especially in populations with high consanguinity.
Area of Science:
- Gastroenterology
- Hematology
- Genetics
Background:
- Inflammatory bowel disease (IBD), encompassing ulcerative colitis and Crohn's disease, is linked to coagulation abnormalities and a hyper-coagulable state.
- Understanding risk factors for thromboembolic events in IBD is critical, particularly in populations with high consanguinity.
Purpose of the Study:
- To investigate the risk factors associated with thromboembolic events in patients diagnosed with inflammatory bowel disease (IBD).
- To assess the prevalence of thrombosis in a Saudi IBD population with a high rate of consanguinity.
Main Methods:
- A prospective cohort study involving 100 Saudi patients with IBD (72% Crohn's disease, 28% ulcerative colitis) was conducted over one year.
- Data collection utilized specifically designed case report forms (CRFs) by trained research personnel.
- Statistical analysis adjusted for age and gender to identify significant predictors of thrombosis.
Main Results:
- Eight percent (8%) of IBD patients experienced at least one thrombotic event, including deep venous thrombosis (DVT) and pulmonary embolism (PE).
- A family history of deep venous thrombosis was present in 5% of patients, and a family history of pulmonary embolism in 4%.
- A family history of any thrombotic event was the sole statistically significant predictor of thrombosis in IBD patients (Risk Ratio = 9.22).
Conclusions:
- Thromboembolic events occurred in 8% of IBD patients within a high consanguinity population.
- A positive family history of pulmonary embolism emerged as a predictor of thrombosis.
- Further research is warranted to elucidate the role of genetic factors in IBD-associated thrombosis within this demographic.
Background/Aims:
Inflammatory bowel disease (ulcerative colitis and Crohn's disease) is characterized by a chronic inflammatory condition, and is accompanied by abnormalities in coagulation and a hyper-coagulable state. This study was conducted to examine the risk factors for developing Thromboembolic Events in Inflammatory Bowel Disease (IBD) in a population with prevalent consanguinity.
Patients And Methods:
Patients with a definitive diagnosis of IBD who were seen in the gastroenterology clinic of King Khalid University Hospital (Riyadh, Saudi Arabia) from 2010- to 2012, were asked to participate in this prospective cohort study, and were followed for one 1 year. Data was collected using specifically designed case report forms (CRF) by trained research personnel.
Results:
A total of 100 Saudi patients with IBD were studied. There were 51 (51%) women and the mean ± standard deviation (SD) age of the group was 31.24 ± 10.78 years. Those with Crohn's disease constituted 72% of the patients, and 28% had ulcerative colitis. Eight patients (8%) had at least one Thrombotic Event ([six deep venous thrombosis (DVT), and two pulmonary embolism (PE)]. Family history of deep venous thrombosis was present in 5%, and family history of pulmonary embolism (PE) in 4% of the patients. After adjusting for age and gender, a family history of Thrombotic event was identified as to be the only statistically significant predictor of thrombosis in IBD patients (RR = 9.22, 95% CI: 2.10--40.43).
Conclusion:
In a population with high consanguinity, Thromboembolic events (DVT and PE) had a prevalence of 8% among IBD patients, positive family history of pulmonary embolism was a predictor of thrombosis. Further studies are needed to explore the role of genetic factors in this population.

Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...
