Insights

Antifungal medications can cause liver injury, though severe liver failure is rare. Early drug cessation and treatment often lead to good outcomes for patients experiencing adverse liver effects.

Area of Science:

  • Pharmacology
  • Hepatology
  • Clinical Medicine

Background:

  • Antifungals are essential antimicrobial drugs.
  • Severe acute liver failure (SALF) from antifungals is a rare but serious clinical concern.
  • Risk assessment for drug-induced liver injury (DILI) from oral antifungals is needed.

Purpose of the Study:

  • To approximate the risk of clinical acute liver injury (ALI) in the general population using oral antifungals.
  • To review existing literature on antifungal-associated liver injury.
  • To inform clinical practice regarding monitoring and management.

Main Methods:

  • Systematic review adhering to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.
  • Inclusion of six articles: case reports and cohort studies.
  • Exclusion of randomized controlled trials due to limited availability.

Main Results:

  • A significant association was found between the duration of antifungal use and elevated liver enzyme levels across all included studies.
  • While acute liver failure is uncommon, prompt drug discontinuation and appropriate medical management generally result in a favorable prognosis.
  • No randomized controlled trials were identified, limiting the strength of evidence.

Conclusions:

  • Oral antifungals are associated with an increased risk of liver enzyme elevation, with duration of use being a key factor.
  • Prompt recognition and management of drug-induced liver injury are crucial for positive patient outcomes.
  • Pre-treatment liver function assessment and regular monitoring (every 3-6 weeks) are recommended for patients on antifungal therapy.

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...

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...

Effect of Hepatic Disease on Pharmacokinetics: Dose Adjustments Due to Hepatic Impairment

Hepatic impairment, characterized by decreased liver function, does not uniformly mandate adjustments in drug dosage. Whether dosage modifications are necessary depends on various factors related to the drug's metabolism and elimination pathways. If a drug is primarily excreted via the kidneys and bypasses significant hepatic processing, if it undergoes minimal metabolic transformation in the liver, or if it is volatile and primarily expelled through the lungs, dose adjustments may not be...

Effect of Hepatic Disease on Pharmacokinetics: Active Drug, Metabolite and Fraction of Metabolized Drug

In pharmacotherapy, monitoring drug concentrations is paramount, especially for drugs whose therapeutic effects hinge on both the active compound and its metabolite. Hepatic impairment profoundly influences drug potency by altering liver function. If the drug is more potent than its metabolite, impaired liver function amplifies drug activity due to elevated drug concentration levels. Conversely, if the metabolite holds greater potency, diminished liver function diminishes drug activity by...

Diseases of the Liver and Gallbladder

Liver and gallbladder diseases are a significant health concern, with prominent conditions including cirrhosis, hepatitis, non-alcoholic fatty liver disease (NAFLD), and gallstones. Jaundice is a common manifestation of liver and biliary disease.
Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not...

Acute Pancreatitis I: Introduction

Pancreatitis is inflammation of the pancreas, an organ located behind the stomach. It can be either acute or chronic.
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:
