Determine the benefit of oral vancomycin therapy for Primary Sclerosing Cholangitis.
|Study Design:||Endpoint Classification: Efficacy Study
Intervention Model: Single Group Assignment

Primary Purpose: Treatment
|Official Title:||Treatment of Primary Sclerosing Cholangitis in Inflammatory Bowel Disease Patients With Oral Vancomycin by the Study of Its Antimicrobial and Immunomodulating Effects|
- Determine the benefit of oral vancomycin therapy for Primary Sclerosing Cholangitis within 3 months of therapy. [ Time Frame: Within 3 months of therapy ] [ Designated as safety issue: No ]Determine the benefit of oral vancomycin therapy for Primary Sclerosing Cholangitis. Blood tests(liver enzymes - ALT and GGT), imaging studies (MRI, ERCP) and/or liver biopsy changes before and while on oral vancomycin will assess the benefit of the therapy.

Experimental: Oral Vancomycin
1) For children who weight < or = 30 kg, the vancomycin dose will be 50 mg/kg/day given orally 3 times per day for the 1st month and continue with the same dose for subsequent months if the clinical laboratory studies improved and are normal. If the laboratory studies are not normal the dose will be increased to 75 mg/kg/day given orally 3 times per day for the 2nd month and 100mg/kg/day given orally 3 times per day the 3rd month. If the laboratory studies do not improve by the end of the 3rd month since starting the vancomycin, the vancomycin will be stopped and the child will not continue the study. 2) For adults and children who weigh >30 kg, the vancomycin dose will be 500 mg given orally 3 times per day for the 1st month and continue with this dose if the clinical laboratory studies improve and are normal. If the laboratory studies are not normal the dose will be increased to 750 mg 3 times per day for the 2nd month and 1000 mg 3 times per day the 3rd month.
Drug: Oral Vancomycin
Other Name: Vancocin
The purpose of this study is to evaluate changes in the fecal and salivary microbiota during vancomycin treatment of children and adults with Primary Sclerosing Cholangitis (PSC), identify features of the host microbiota that are associated with disease activity and/or response to treatment and further delineate the immunological effects of oral vancomycin treatment of PSC. This study will correlate changes in microbiota with the immunological effects of oral vancomycin in children and adults with PSC. The results of this proposal will lead to new and validated targets for diagnosis and treatment of PSC that will have high impact in the short and long term for patients and their families.
