Systematic Review of Antifungal-Induced Acute Liver Failure

Abstract:
Antifungals are effective antimicrobial agents broadly used in medical practice. Severe acute liver failure from oral or IV administration of antifungals is a rare but long-standing clinical challenge. We aimed to approximate the risk of clinical acute liver injury among users of oral antifungals in the general population. This review was completed based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Six articles were included, comprising case reports and cohort studies, after eliminating duplicate publications. No randomized control studies were found. In all studies, the duration of antifungal use was associated with significantly increased liver enzyme levels. Although it is not very common for patients on antifungals to develop acute liver failure, the prognosis is often good with swift discontinuation of the drug and proper treatment. Liver function evaluation before treatment and periodic monitoring every three to six weeks after commencement of treatment is suggested.
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.

Acute Pancreatitis I: Introduction
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:
