Summary
Primary sclerosing cholangitis (PSC) often co-occurs with other immune-mediated diseases, particularly inflammatory bowel disease (IBD). While IBD is linked to earlier PSC diagnosis, other immune conditions do not significantly impact patient outcomes.
Area of Science:
- Hepatology
- Immunology
- Gastroenterology
Background:
- Primary sclerosing cholangitis (PSC) is a chronic liver disease with suggested immune origins.
- Associations between PSC and inflammatory bowel disease (IBD) are known, but data on other concomitant immune-mediated diseases is limited.
Purpose of the Study:
- To determine the prevalence of other immune-mediated diseases in patients with PSC.
- To investigate the impact of these concomitant diseases on PSC outcomes.
Main Methods:
- Retrospective review of medical charts for 241 PSC patients.
- Analysis of concomitant immune-mediated diseases and their correlation with disease characteristics and outcomes.
Main Results:
- A high prevalence (71.4%) of concomitant immune-mediated diseases was observed in PSC patients.
- Inflammatory bowel disease (IBD) was the most common (61.8%), followed by autoimmune hepatitis (6.2%).
- Younger age at PSC diagnosis was associated with IBD, while other immune diseases correlated with later diagnosis; IBD was linked to longer survival.
Conclusions:
- Concomitant immune-mediated diseases are highly prevalent in PSC.
- IBD is associated with earlier PSC onset, whereas other immune diseases appear in later-onset PSC.
- Non-IBD immune-mediated diseases did not affect PSC outcomes.

01:17Chronic Bowel Disorders: Introduction
Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

01:20Cholecystitis
Cholecystitis is inflammation of the gallbladder, most commonly caused by obstruction of the cystic duct. This blockage prevents bile from draining, leading to gallbladder distension, inflammation, and potentially serious complications. This condition may present acutely or chronically and can happen with or without gallstones.EtiologyAbout 95% of cholecystitis cases are calculous, caused by gallstones blocking the cystic duct, leading to bile accumulation and inflammation of the gallbladder...
01:25Inflammatory Bowel Disease III: Crohn's Disease
Crohn’s disease is a chronic, relapsing form of inflammatory bowel disease characterized by segmental, transmural inflammation that can affect any part of the gastrointestinal tract. Its pathogenesis arises from a combination of genetic susceptibility, environmental exposures, epithelial barrier dysfunction, and immune dysregulation. Together, these factors lead to an exaggerated immune response against components of the gut microbiome.Genetic and Environmental InfluencesMultiple genetic...

Introduction
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

01:26Diseases of the Liver and Gallbladder
Liver and gallbladder diseases are a significant health concern, with prominent conditions including cirrhosis, hepatitis, non-alcoholic fatty liver disease (NAFLD), and gallstones. Jaundice is a common manifestation of liver and biliary disease.
Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not related to...

01:21Chronic Pancreatitis II: Pathophysiology
Chronic pancreatitis is a progressive and irreversible inflammation of the pancreas, most often caused by long-term alcohol abuse, but it can also be related to ductal obstruction, smoking, or genetic factors.Chronic pancreatitis occurs when the pancreas is repeatedly exposed to harmful agents like alcohol, smoking, ductal obstruction, or genetic predisposition. These factors lead to the release of toxic metabolites and inflammatory cytokines, sustaining chronic inflammation in the pancreatic...
