Viral hepatitis-induced acute liver failure.

Area of Science:

• Hepatology
• Infectious Diseases
• Public Health

Background:

• Viral hepatitis is a significant cause of acute liver failure (ALF), particularly in developing nations.
• Acetaminophen overdose is a primary cause of ALF in Western countries.
• Hepatotropic viruses or systemic infections can lead to ALF.

Purpose of the Study:

• To highlight the importance of differentiating viral hepatitis-induced ALF from mimics like leptospirosis, scrub typhus, and malaria.
• To outline current treatment strategies for viral hepatitis-induced ALF.
• To emphasize preventive measures for viral hepatitis.

Main Methods:

• Review of viral hepatitis as a cause of ALF.
• Discussion of differential diagnoses for ALF in tropical regions.
• Overview of supportive care, antiviral therapy, and liver transplantation (LT) for ALF.

Main Results:

• Viral infections are a leading cause of ALF globally, necessitating specific therapeutic approaches.
• Accurate diagnosis is crucial for effective, etiology-specific treatment of ALF.
• Liver transplantation and bridging modalities are essential for severe cases.

Conclusions:

• Prompt identification and management of viral hepatitis-induced ALF, alongside preventive strategies, can significantly reduce liver-related mortality.
• Public health initiatives including vaccination and hygiene are key to prevention.
• Early referral for liver transplantation is critical for patient survival.
