Gastritis-II: Pathophysiology

463
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...

Myasthenia Gravis: Overview and Treatment

1.8K
Myasthenia gravis is a neuromuscular transmission disorder characterized by weakness and increased fatigability of skeletal muscles. It is an autoimmune disease affecting approximately one in 2000 people, where antibodies against the α1 subunit of nicotinic acetylcholine receptors are produced.
These antibodies interfere with the function of the nicotinic receptors in three ways: by binding to the receptor and disrupting acetylcholine binding; by causing cross-linking of receptors which...

Chronic Pancreatitis I: Introduction

135
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: Introduction01:17

Chronic Bowel Disorders: Introduction

525
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...

Autoimmune Disorders

621
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.
Concept and Mechanism of Autoimmune Diseases

Area of Science:

  • Hepatology
  • Immunology
  • Autoimmunity

Background:

  • Primary biliary cholangitis (PBC) is a chronic, immune-mediated liver disease.
  • It involves lymphocytic cholangitis, cholestasis, and progressive liver fibrosis.
  • End-stage liver disease complications are a major concern in PBC.

Purpose of the Study:

  • To review the diagnostic significance of autoantibodies in PBC.
  • To examine the relationship between autoantibodies, PBC pathophysiology, and prognosis.
  • To discuss novel and related disease autoantibodies in the context of PBC.

Main Methods:

  • Literature review focusing on autoantibodies in PBC.
  • Analysis of diagnostic and prognostic roles of autoantibodies.
  • Discussion of current and emerging autoantibody markers.

Main Results:

  • Autoantibody testing is vital for PBC diagnosis and prognosis stratification.
  • Specific autoantibodies correlate with disease mechanisms and progression.
  • Novel autoantibodies may offer new diagnostic and prognostic insights.

Conclusions:

  • Autoantibodies are indispensable tools in managing primary biliary cholangitis.
  • Understanding autoantibody profiles aids in personalized patient management.
  • Further research into novel autoantibodies can refine PBC diagnosis and treatment.
