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

Primary Sclerosing Cholangitis Clinical Trial

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

Clinical Trial 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.

Clinical Trial Description

The used antibiotic is Metronidazole (Flagyl), during 14 days, as induction therapy or rescue therapy. Study participants will provide blood and stool samples in order to evaluate bile acids profile and microbiome, before and after the course of metronidazole, and then comparison will be made pre- and post-antibiotics. The investigators will determine the benefit of oral metronidazole therapy through improvement of clinical symptoms and improvement of liver function tests. ;
