Advances and controversies in the pathogenesis and management of primary sclerosing cholangitis

Introduction:
Primary sclerosing cholangitis (PSC) is a chronic immune-mediated liver disease that results in end-stage liver disease requiring liver transplantation. PSC is closely associated with inflammatory bowel disease (IBD) with 70% of patients with PSC also suffering from IBD.
Sources Of Data:
Data for this review were obtained from PubMed.
Areas Of Agreement:
Historical and genome-wide association studies have established a strong human leukocyte antigen (HLA) linkage to PSC and defined specific haplotypes associated with enhanced PSC risk. Fifteen non-HLA loci have been defined in PSC.
Areas Of Controversy:
The biological role of risk loci in PSC and their place in PSC pathogenesis remain speculative but suggest significant interactions with the host microbiome and therapeutic opportunities.
Growing Points:
Genetics provides a platform to systematically target emerging therapies in PSC.
Areas Timely For Developing Research:
Linking PSC genotypes with biology and disease phenotypes paves the way for a personalized medicine approach to manage PSC.

Chronic Pancreatitis I: Introduction
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...
