Effect of Hepatic Disease on Pharmacokinetics: Pathophysiologic Assessment and Liver Function Test01:22

Effect 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...

Effect 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...

Chronic Kidney Disease III: Interprofessional Care

Chronic kidney disease (CKD) requires collaborative and comprehensive management. CKD progresses through stages and can lead to end-stage kidney disease (ESKD) if untreated. Interprofessional collaboration and patient education are crucial, enabling patients to manage their health and improve their quality of life.Diagnostic approach for chronic kidney diseaseThe diagnosis of CKD primarily focuses on the glomerular filtration rate (GFR), which assesses kidney function by measuring how well...
Esophageal Varices-II: Clinical Features and Management01:28

Esophageal Varices-II: Clinical Features and Management

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.
In the initial assessment, a thorough review of the patient's medical history is vital to identify risk factors such as liver disease, alcohol abuse, or...
Cirrhosis II: Pathophysiology01:24

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...
Liver Physiology01:30

Liver 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...

Summary

Critically ill patients often receive excessive calories, leading to artificial nutrition-associated liver dysfunction. This review explores the pathogenesis, linking it to overfeeding, sepsis, and metabolic syndrome similarities.

Area of Science:

  • Critical care medicine
  • Hepatology
  • Nutritional science

Background:

  • Current guidelines often recommend excessive caloric intake for critically ill patients, contrary to emerging evidence.
  • This overfeeding practice, especially in septic patients, is linked to adverse outcomes and liver dysfunction.

Purpose of the Study:

  • To review recent developments in the pathogenesis of artificial nutrition-associated liver dysfunction (ANALD) in critically ill patients.
  • To highlight the role of overfeeding and sepsis in ANALD.

Main Methods:

  • Literature review focusing on recent research.
  • Analysis of experimental evidence on metabolic alterations in critically ill patients.

Main Results:

  • The liver's role in metabolism and inflammation is crucial in critical illness.
  • Insulin resistance and altered glucose/lipid metabolism are key features, potentially mirroring type 2 diabetes and metabolic syndrome.
  • Excess glucose and lipids, combined with inflammation, can induce liver dysfunction and steatosis.

Conclusions:

  • ANALD pathogenesis involves overfeeding and sepsis, sharing similarities with metabolic syndrome and type 2 diabetes.
  • Modifying nutritional strategies and incorporating new drugs may help prevent ANALD.
