Official Title: " Overlap Syndrome and PSC: Evaluating Role of Gut Microflora and Its Modification With Antibiotics in Children"

Brief Summary:

Based upon the possible implication of microbiota and abnormal microbial metabolites such as altered bile acids, in the pathogenesis of PSC, emerging data suggests that oral antibiotics, such as vancomycin and metronidazole, may have therapeutic effects in this overlap syndrome or PSC.

The goal of our study is to evaluate role of antibiotics and microflora in children with AIH/PSC overlap syndrome or with PSC alone. The investigators hope to learn what effects oral antibiotics has on the bacteria present in stool, and hope to learn to characterize human intestinal microbial communities, in children suffering from overlap syndrome or PSC.

The hypothesis of the investigators is that overlap syndrome and PSC develop due to altered microflora and the resulting abnormal bile acids pool. The outcome of overlap syndrome or PSC could be affected by presence or absence of RCUH. Antibiotics to correct the microflora may result in disease/cholangiopathy remission.
