Cirrhosis II: Pathophysiology

Cirrhosis II: Pathophysiology

Cirrhosis is a progressive chronic liver injury caused by prolonged inflammation, excessive fibrotic remodeling, and impaired regeneration. Over time, repeated hepatic insults disrupt the liver’s architecture and function, leading to reduced blood flow, impaired bile drainage, and diminished metabolic capacity.Pathophysiology of cirrhosisCirrhosis arises from three main responses to chronic liver damage: inflammation, immune activation, and hepatocyte death. These processes lead to structural...

Toxic Reactions: Overview

Toxic Reactions: Overview

When toxic substances penetrate the human body, they disseminate to various tissues, undergoing metabolic changes. This process yields reactive metabolites that may covalently bind with specific target molecules, resulting in toxicity.
Toxicity falls into two primary categories: local and systemic.
Local toxicity appears at the exposure site, such as protein denaturation caused by caustic substances.
In contrast, systemic toxicity requires the toxic agent's absorption and distribution,...

Hepatic Encephalopathy

Hepatic Encephalopathy

DefinitionHepatic encephalopathy is a reversible neurologic syndrome that results from advanced liver dysfunction or portosystemic shunting. It leads to disturbances in cognition, behavior, and motor function due to the brain’s exposure to gut-derived toxins that the liver fails to detoxify.EtiologyThis condition develops either in the setting of acute fulminant hepatitis or progressively during chronic liver disease, such as cirrhosis and portal hypertension. Portosystemic shunting—including...

Cirrhosis I: Introduction

Cirrhosis I: Introduction

Cirrhosis is a chronic, irreversible liver disease characterized by the widespread replacement of healthy liver tissue with fibrotic scar tissue and the formation of regenerative nodules.Etiology of cirrhosisCirrhosis results from sustained liver injury that triggers progressive fibrosis and structural remodeling. The underlying causes are diverse, encompassing common and less frequent clinical conditions. Regardless of the origin, all causes lead to chronic inflammation, hepatocyte loss, and...

Cellular Injury I: Introduction

Cellular Injury I: Introduction

Cellular injury occurs when a cell cannot maintain homeostasis or adapt to stressors such as hypoxia, toxins, or trauma. Depending on severity and duration, injury may be reversible, allowing recovery, or irreversible, leading to cell death.General Mechanisms of Cell InjuryAlthough causes vary, most cellular injuries arise from a few key mechanisms that disrupt essential functions and often amplify one another. Cell survival depends on the extent and balance of these disturbances.ATP depletion...

Drug Toxicity: Overview

Drug Toxicity: Overview

Drug toxicity quantifies the harm a compound causes to an organism, varying by dose and potentially impacting whole systems or specific organs like the liver. Toxic reactions may arise from venomous insect or spider bites, with effects ranging from mild symptoms to severe outcomes such as brain damage or death. Common forms of acute poisoning include ethanol intoxication and overdose of pain or fever medications, with substances like GHB and heroin being particularly lethal at doses close to...

Area of Science:

Toxicology
Occupational Medicine
Hepatology

Background:

Toxic liver injury is a major health concern in occupational medicine.
Exposure to xenobiotics can cause acute or chronic liver damage.
Liver injury manifests as cell regeneration, functional loss, or necrosis.

Purpose of the Study:

To present current knowledge on the pathogenesis of morphological changes in hepatocytes.
To review how xenobiotics induce liver injury.
To discuss the different phenotypes of drug- or chemical-induced liver injury.

Main Methods:

Review of current literature on toxic liver injury.
Analysis of xenobiotic-induced hepatotoxicity.
Discussion of morphological changes in hepatocytes.

Main Results:

Xenobiotic exposure leads to diverse toxicological responses in the liver.
Morphological changes in hepatocytes define injury phenotypes.
Common phenotypes include cholestatic injury, hepatocellular injury, mitochondrial damage, and delayed immunological injury.

Conclusions:

Understanding the pathogenesis of hepatocyte morphological changes is crucial for managing toxic liver injury.
Identifying injury phenotypes aids in diagnosing and treating liver damage from xenobiotics.
Further research into xenobiotic-induced liver injury is warranted.
