Summary
Therapeutic strategies for acute liver failure, including bioartificial and artificial liver support, are reviewed. While these systems show promise in improving patient parameters, further development is needed to enhance survival rates.
Area of Science:
- Hepatology
- Biomedical Engineering
- Critical Care Medicine
Background:
- Acute liver failure (ALF) presents a high mortality rate, with liver transplantation being the primary but limited treatment.
- Understanding the complex pathophysiology of ALF is crucial for developing effective interventions.
- Extracorporeal liver support aims to bridge patients to recovery or transplantation.
Purpose of the Study:
- To summarize therapeutic approaches for acute liver failure, focusing on bioartificial and artificial liver support systems.
- To review recent advances in understanding ALF pathophysiology and their impact on treatment strategies.
- To evaluate the current status and future directions of extracorporeal liver support.
Main Methods:
- Review of current literature on acute liver failure treatments.
- Analysis of bioartificial liver support (BALS) systems utilizing hepatocytes.
- Evaluation of artificial liver support (ALS) systems for toxin removal.
Main Results:
- Both BALS and ALS systems can be safely applied and improve clinical and biochemical parameters in ALF patients.
- BALS devices have not yet demonstrated improved survival rates, but ongoing development is promising.
- ALS systems show potential in modulating ALF's pathophysiological mechanisms, though survival data remain limited.
Conclusions:
- Despite advances, mortality in acute liver failure remains high, necessitating alternative therapeutic options beyond transplantation.
- Further research into ALF pathophysiology and device engineering is essential for effective extracorporeal liver assist.
- Bioartificial and artificial liver support represent critical areas for future therapeutic development in ALF management.

01:26Effect of Hepatic Disease on Pharmacokinetics: Drug Dosing and Hepatic Blood Flow
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 binding...
01:22Effect of Hepatic Disease on Pharmacokinetics: Pathophysiologic Assessment and Liver Function Test
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 the...

01:24Liver Regeneration
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.

01:30Liver Physiology
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 also...

Esophageal varices often manifest as gastrointestinal bleeding episodes, presenting symptoms like hematemesis (vomiting of blood), hematochezia (passing fresh blood via the rectum), and melena (black, tarry stools). Other signs can include weight loss, anorexia, abdominal discomfort, jaundice, pruritus, altered mental status, and muscle cramps.
