Brief Summary: Background

Primary sclerosing cholangitis is a rare chronic liver disease It affects the bile ducts of the

liver It can result in bile duct infections cirrhosis cancer and end stage liver disease Researchers want to learn more about this disease

Objective

To understand the biological causes of primary sclerosing cholangitis

Eligibility

Adults age 18 and older who have primary sclerosing cholangitis

Design

Participants will be screened with a medical history physical exam and blood tests

Participants will give blood saliva urine and stool samples They will have nasal swabs They will complete surveys

Participants will get an intravenous IV catheter A plastic tube is inserted into an arm vein

Participants will have a colonoscopy A tube with a video camera at the end is inserted into the rectum

Participants will have an upper endoscopy A scope with a light and camera at its tip is used to look inside the upper digestive tract

Participants will have a liver biopsy entering through the chest wall or a neck vein Blood is drawn from a blood vessel that carries blood to the liver A liver tissue sample is taken

Participants will have magnetic resonance imaging or spectroscopy They will get a contrast agent through an IV

Participants may have an optional bone marrow aspiration A large needle is inserted into the hip to withdraw marrow

Participants will have a liver ultrasound

Participants will complete a 3-day food diary They will have a nutrition assessment

Participants may give contact details for people who live with them to also take part in this study

Participation will last for 12 months
Detailed Description: Study Description

We hypothesize that primary sclerosing cholangitis PSC develops as a consequence of a genetically driven aberrant immune response to commensal or pathogenic bacteria and that unique genetic-immunemicrobial associations may underlie development of distinct disease patterns We intend to conduct a thorough radiologic endoscopic histologic and microbiological investigation of patients with PSC in order to determine potential associations

Objectives

Primary Objective

The ultimate goal of this study is to generate understanding of how factors driving pathogenesis in PSC interact by capturing and integrating collated datasets from across relevant biologic systems and interpreting those in the context of phenotypic presentation in one exceptionally well-characterized set of patients

Secondary Objectives

1 To collect comprehensive data on distinct patterns of disease expression through single cell sequencing and microRNA and transcriptome profiling
2 To conduct extensive phenotypic characterization of cellular and humoral immune responses as well as microbiome signatures at multiple anatomic sites
3 To evaluate metabolic signatures or biomarkers for PSC diagnosis and prognostication
4 To generate a humanized mouse model of each subject s disease by obtaining bone marrow aspirate

Endpoints

Primary Endpoint

1 Identification of immune signatures at multiple levels and from different anatomical sites and tissues
2 Characterization of microbiome signatures taxonomic and functional as well as identification of specific species
3 Identification of metabolomic signatures from different anatomical sites and tissues as well as identification of different biomarkers correlating with disease progression
4 MicroRNA profiling of portal and systemic blood
