Seroprevalence of Anti-bodies Against Clostridium Difficile Toxins and Prevalence of Asymptomatic Carriage of Clostridium Difficile in IBD Patients.

• Conditions: Clostridium Difficile; Inflammatory Bowel Diseases

• Registration Number: NCT03889808
• Lead Sponsor: Hospital Universitari de Bellvitge

Brief Summary

The objective of this study to evaluate the seroprevalence of anti-bodies against C. difficile toxins A and B and the asymptomatic carriage of C. difficile in IBD patients according to the need and type of immunosuppressive therapy. The ultimate goal is to identify, among IBD patients, those with the highest risk of CDI.

Primary Outcome Measures

Name	Time	Method
Prevalence of Clostridium difficile anti-toxin Abs in patients with IBD	0 days	Determination of serum anti-toxin Abs for C. difficile with ELISA (enzyme-linked immunosorbent assay). The concentration of C. difficile anti-toxin Abs will be categorized as: \< 25 percentile: Low, \>26 \< 75 percentiles: Intermediate, \>76 \<90 percentiles: High, \>91 percentile: Very high.
Prevalence of asymptomatic carrier of Clostridium difficile in patients with IBD	0 days	Stool testing for C. difficile as part of a multiple step algorithm: GDH (glutamate dehydrogenase), toxin EIA (enzyme immunoassay) test and C. difficile culture.
Study the relationship between the different maintenance therapies for IBD and C. difficile anti-toxin Abs and asymptomatic carriers.	0 days
