Gastritis-II: Pathophysiology

354
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...

Nephrotic Syndrome I : Introduction

9
Nephrotic Syndrome is a chronic kidney disorder defined by clinical findings such as severe proteinuria, hypoalbuminemia, hyperlipidemia, and edema. These symptoms result from damage to the glomeruli, the kidney’s filtering units, increasing their permeability to proteins.Definition and Meaning:Proteinuria, defined as the loss of more than 3.5 grams of protein per day in adults, is a crucial feature of nephrotic syndrome. This condition is often accompanied by edema, the accumulation of...

Liver Regeneration

3.3K
The liver is an important organ in vertebrates that plays an essential role in metabolism. It is also responsible for storing and redistributing nutrients such as carbohydrates, fats, and vitamins in the body. Additionally, the liver releases bile salts which are critical for digesting food and eliminating toxic metabolites from the body.
Cells of Liver
The liver comprises four major types of cells— hepatocytes, stellate, Kupffer, and sinusoidal endothelial cells. The hepatocytes are...

Cells of the Innate Immune Response

1.7K
The innate immune response is an immediate and non-specific response against pathogens, acting swiftly to prevent the spread of infections. The primary cells involved in this response are phagocytes and natural killer (NK) cells.
Phagocytes
Phagocytes police the peripheral tissues by removing cellular debris and responding to the invasion of foreign substances or pathogens. Many phagocytes attack and remove microorganisms even before lymphocytes detect them. The human body has two general...

Differentiation of Common Myeloid Progenitor Cells

3.2K
Common myeloid progenitors (CMPs) are oligopotent cells that can differentiate into granulocytes and macrophages. Granulocytes and macrophages are essential for protecting the body against bacterial, viral, or fungal infections. They migrate from the bone marrow into the circulating blood to reach specific tissue sites where they differentiate and help in immune surveillance. However, they survive only for a few days and must be continuously made available to the organism to maintain a robust...

Area of Science:

  • Immunology
  • Hepatology
  • Microbiology

Background:

  • Neutrophils are key innate immune cells crucial for pathogen defense.
  • Cirrhosis significantly alters neutrophil functions, including phagocytosis and bacterial killing.
  • Impaired neutrophil function in cirrhosis leads to increased susceptibility to infections.

Purpose of the Study:

  • To review current knowledge on neutrophil dysfunction in cirrhosis.
  • To identify proposed causes of altered neutrophil function.
  • To highlight knowledge gaps and future research directions.

Main Methods:

  • Literature review of studies on neutrophil function in cirrhosis.
  • Analysis of cellular and serum factors affecting neutrophil function.
  • Synthesis of existing data on neutrophil extracellular trap (NET) formation.

Main Results:

  • Neutrophils in cirrhosis show impaired phagocytosis, bacterial killing, chemotaxis, degranulation, ROS production, and NET formation.
  • Multidrug-resistant infections are a growing concern in cirrhosis patients.
  • The exact causes of neutrophil dysfunction remain incompletely understood.

Conclusions:

  • Neutrophil dysfunction is a significant contributor to infectious complications in cirrhosis.
  • Targeting neutrophil dysfunction presents a potential therapeutic strategy.
  • Further research is needed to elucidate the mechanisms and develop effective interventions.
