Liver Regeneration01:24

Liver Regeneration

4.1K
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...

Liver Physiology

3.8K
The liver, an essential organ in the human body, performs over 200 vital functions that can be broadly categorized into metabolic, hematological, endocrine regulation, and bile production.
Metabolic Regulation:
The liver is the central organ involved in regulating blood composition. It stabilizes blood glucose levels, maintaining them within the range of  70–110 mg/dL. When these levels drop, the liver breaks down glycogen reserves and releases glucose into the bloodstream. It can...

Effect of Hepatic Disease on Pharmacokinetics: Drug Dosing and Hepatic Blood Flow01:26

Effect of Hepatic Disease on Pharmacokinetics: Drug Dosing and Hepatic Blood Flow

382
Chronic liver disease significantly impacts drug metabolism due to alterations in hepatic blood flow and enzyme accessibility. This disruption affects the body's pharmacokinetics—the movement and processing of drugs within the system. Key enzymes crucial for metabolizing medications become less accessible, changing how drugs are processed and utilized. Furthermore, liver disease influences the synthesis of plasma proteins, such as albumin and globulins, which play critical roles in drug...

Effect of Hepatic Disease on Pharmacokinetics: Pathophysiologic Assessment and Liver Function Test

271
In clinical practice, the direct measurement of hepatic blood flow to evaluate liver function presents significant challenges due to the intricate and specialized nature of the necessary techniques. Consequently, healthcare professionals often rely on empirical estimates derived from thorough patient examinations and liver function tests to gauge liver health. Among the tools at their disposal, the Child–Pugh and MELD scoring systems stand out for their ability to categorize and assess...

Cirrhosis I: Introduction01:23

Cirrhosis I: Introduction

28
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...

Cirrhosis II: Pathophysiology01:24

Cirrhosis II: Pathophysiology

42
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...

Summary
This summary is machine-generated.

Patients with alcoholic liver disease often have impaired splenic function, indicated by a higher percentage of pitted red blood cells. This functional hyposplenism may increase infection risk in these individuals.

Area of Science:

  • Hepatology
  • Immunology
  • Hematology

Background:

  • Alcoholic liver disease (ALD) is associated with increased susceptibility to infections.
  • The spleen plays a crucial role in immune surveillance and clearing pathogens.
  • Functional hyposplenism, a state of reduced splenic function, is a known risk factor for severe infections.

Purpose of the Study:

  • To investigate splenic function in patients with alcoholic liver disease.
  • To determine if alcoholic liver disease is associated with functional hyposplenism.
  • To explore the relationship between hyposplenism, liver disease severity, and infection risk.

Main Methods:

  • Assessed splenic function by quantifying pitted erythrocytes using differential interference contrast microscopy in 42 ALD patients and 42 controls.
  • Pitted erythrocytes represent cellular debris normally cleared by the spleen, with higher counts indicating reduced splenic function.
  • Compared pitted red cell counts between patients and controls, and correlated findings with disease severity (cirrhosis, ascites) and infection history.

Main Results:

  • Patients with ALD exhibited significantly higher mean pitted red cell counts (2.7%) compared to controls (0.7%) (p < 0.001).
  • Eight reformed drinkers had normal pitted red cell counts.
  • 18 patients had elevated counts, with 11 having cirrhosis and/or ascites; two patients with severe infections had evidence of hyposplenism.

Conclusions:

  • This study demonstrates the presence of functional hyposplenism in patients with alcoholic liver disease.
  • Functional hyposplenism in ALD patients may contribute to their increased predisposition to infections.
  • Further research is needed to elucidate whether alcohol toxicity or cirrhosis underlies this hyposplenism.
