Chronic Pancreatitis I: Introduction01:24

Chronic Pancreatitis I: Introduction

804
The pancreas, an elongated and flat gland situated behind the stomach, serves a vital function in digesting food and managing blood sugar levels.
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...

Chronic Bowel Disorders: Introduction

853
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...

Gastritis-II: Pathophysiology

1.5K
Gastritis is marked by disruption of the mucosal barrier that usually protects the stomach tissue from digestive juices and manifests in acute and chronic forms.
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...

Autoimmune Disorders01:29

Autoimmune Disorders

2.0K
Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.

Diseases of the Liver and Gallbladder

2.1K
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...

Summary
This summary is machine-generated.

Current evidence is insufficient to distinguish autoimmune cholangitis (AIC) from primary biliary cholangitis (PBC). Further research into causes and mechanisms is needed to determine if AIC is a separate disease from AMA-positive PBC.

Area of Science:

  • Hepatology
  • Immunology
  • Gastroenterology

Background:

  • Primary biliary cholangitis (PBC) is an autoimmune liver disease.
  • Autoimmune cholangitis (AIC) is defined as AMA-negative PBC with ANA or SMA.
  • The distinction between PBC and AIC remains unclear.

Purpose of the Study:

  • To evaluate the current evidence regarding the classification of PBC and AIC.
  • To discuss the potential for AIC to be recognized as a distinct disease entity.

Main Methods:

  • Review of existing scientific literature and evidence.
  • Analysis of diagnostic criteria and serological markers (AMA, ANA, SMA).

Main Results:

  • Current evidence is insufficient to definitively classify AIC as a separate disease from PBC.
  • Further investigation into etiological factors and pathogenetic mechanisms is required.

Conclusions:

  • The term "autoimmune cholangitis" has been proposed for PBC with or without AMA.
  • PBC is likely to remain the established term, with AIC and AMA-negative PBC used interchangeably by hepatologists.
