Prevalence and risk factors for thromboembolic complications in IBD patients

Background: Inflammatory bowel disease (IBD) patients have an increased risk of venous thromboembolic complications (VTEC) such as deep vein thrombosis (DVT) and pulmonary embolism when compared to the non-IBD population. However, studies assessing VTEC prevalence in IBD as well as analyses of VTEC associated risk factors are scarce. We aimed to assess VTEC prevalence in IBD patients and to identify associated risk factors. Methods: Data from patients enrolled in the Swiss IBD Cohort Study (SIBDCS) were analyzed. Since 2006 the SIBDCS collects data on a large sample of IBD patients from hospitals and private practices across Switzerland. Results: A  total of 90/2284 (3.94%) IBD patients suffered from VTEC. Of these, 45/1324 (3.4% overall; 2.42% with DVT, 1.51% with PE) had CD, and 45/960 (4.7% overall; 3.23% with DVT, 2.40% with PE) presented with UC.

Incidence and outcomes of symptomatic neonatal arterial ischemic stroke.

BACKGROUND AND OBJECTIVES: Neonatal arterial ischemic stroke (NAIS) is associated with considerable lifetime burdens such as cerebral palsy, epilepsy, and cognitive impairment. Prospective epidemiologic studies that include outcome assessments are scarce. This study aimed to provide information on the epidemiology, clinical manifestations, infarct characteristics, associated clinical variables, treatment strategies, and outcomes of NAIS in a prospective, population-based cohort of Swiss children. METHODS: This prospective study evaluated the epidemiology, clinical manifestations, vascular territories, associated clinical variables, and treatment of all full-term neonates diagnosed with NAIS and born in Switzerland between 2000 and 2010. Follow-up was performed 2 years (mean 23.3 months, SD 4.3 months) after birth. RESULTS: One hundred neonates (67 boys) had a diagnosis of NAIS. The NAIS incidence in Switzerland during this time was 13 (95% confidence interval [CI], 11-17) per 100 000 live births. Seizures were the most common symptom (95%). Eighty-one percent had unilateral (80% left-sided) and 19% had bilateral lesions. Risk factors included maternal risk conditions (32%), birth complications (68%), and neonatal comorbidities (54%). Antithrombotic and antiplatelet therapy use was low (17%). No serious side effects were reported. Two years after birth, 39% were diagnosed with cerebral palsy and 31% had delayed mental performance. CONCLUSIONS: NAIS in Switzerland shows a similar incidence as other population-based studies. About one-third of patients developed cerebral palsy or showed delayed mental performance 2 years after birth, and children with normal mental performance may still develop deficits later in life.
