Conclusion: The prevalence of HBV infection in IBD patients was similar to that in general population in South China. HBV infection didn’t affect the clinical characters and medicine choices in either CD or UC. HBV-postive CD patients have lower PLT count and less common use of infliximab compared with HBV-negative CD patients. Key Word(s): 1. HBV infection; 2. IBD; 3. Crohn’s Disease; 4.

disease (IBD), and provide a new measurement to monitor disease activity and prognosis. Methods: 85 IBD patients including 54 with ulcerative colitis (UC), 31 with crohn’s disease (CD) and 53 healthy people (Control) were involved in the study. Autonomic nervous function was determined: postural blood pressure change and sustained handgrip test for sympathetic nerve function, and valsalva maneuver, lying to standing heart rate response for vagus nerve function. Results:  1. Postural blood pressure changes were selleck chemicals higher but sustained handgrip test and lying to standing heart rate responses of IBD patients were lower than healthy. 2. Postural blood pressure changes of mild CD patients were lower but sustained handgrip test, valsalva maneuver and lying to standing heart rate responses were higher than that of moderate CD patients. 3. Postural blood pressure changes of the mild UC patients were lower MCE公司 but sustained handgrip test and lying to standing heart rate responses were higher than that of moderate UC patients. Conclusion: IBD patients show autonomic never function disorder, with elevated sympathetic function but decreased vagus function. Autonomic dysfunction of IBD patients is correlated with disease activity, and may be a potential monitoring

marker of disease activity. Key Word(s): 1.

The aim of our study was to identify predictive factors of hospital readmissions in IBD patients. Methods: We retrospectively reviewed the clinical data of IBD patients with first hospitalization between January 2007 and December 2011. Hospital readmission was defined as any subsequent hospitalization related to IBD.
