Fulminant hepatitis: Mayo Clinic experience with 34 cases

Area of Science:

• Hepatology
• Virology
• Toxicology

Background:

• Fulminant hepatitis is a rare but devastating condition with high mortality.
• Understanding the causes and prognostic factors is crucial for improving patient outcomes.

Purpose of the Study:

• To analyze the causes, clinical course, and outcomes of fulminant hepatitis cases.
• To identify factors associated with poor prognosis in fulminant hepatitis.

Main Methods:

• Retrospective review of 34 patients diagnosed with fulminant hepatitis between 1974 and 1982.
• Analysis of etiological factors including viral infections, drug toxicity, Wilson's disease, and industrial poisons.

Main Results:

• A survival rate of only 6% (2 out of 34 patients) was observed.
• Viral hepatitis (B and non-B) accounted for the majority of cases (23 patients).
• Death typically occurred within 10 days of encephalopathy onset, with hepatic failure being the primary cause.

Conclusions:

• Fulminant hepatitis in this cohort had a dismal prognosis, likely influenced by patient age and non-B hepatitis virus etiology.
• Complications such as renal failure, sepsis, and bleeding frequently complicated the clinical course.
• Hepatic failure remains the leading cause of mortality in fulminant hepatitis.
