A 28-year-old man from rural Maharashtra presents with jaundice, dark urine, and abdominal pain for 10 days. He has no prior history of liver disease. Serum bilirubin is 8.2 mg/dL (direct 5.1 mg/dL), ALT 1840 IU/L, AST 1620 IU/L, ALP 180 IU/L. Anti-HAV IgM is positive; anti-HBc, anti-HCV, and anti-HDV are all negative. INR is 1.1, albumin 3.8 g/dL, and he is alert and oriented. What is the most appropriate next step in management?

Explanation

## Clinical Assessment This patient has acute hepatitis A with: - **Serological confirmation:** Anti-HAV IgM positive (diagnostic of acute HAV infection) - **Preserved synthetic function:** INR 1.1, albumin 3.8 g/dL (no fulminant hepatic failure) - **Compensated acute hepatitis:** Alert, oriented, no encephalopathy ## Management Principles for Acute HAV **Key Point:** Acute hepatitis A is self-limited in >99% of immunocompetent adults. Management is entirely supportive; no specific antiviral therapy is indicated or effective. **High-Yield:** HAV does NOT cause chronic infection. Recovery is complete in 3–6 months in the vast majority of cases. ## Appropriate Next Steps 1. **Admission and monitoring** — indicated because: - Severe acute hepatitis (ALT >1500 IU/L) - Need to monitor for fulminant hepatic failure (though risk is low in this age group) - Supportive care: fluid balance, nutritional support, avoid hepatotoxins 2. **Counseling on transmission** — fecal-oral route; hygiene measures essential to prevent spread to household and community 3. **Serial monitoring** — INR, albumin, mental status; escalate to ICU if signs of coagulopathy or encephalopathy develop **Clinical Pearl:** Fulminant hepatic failure in HAV is rare (<0.5%) in immunocompetent adults but more common in those with pre-existing chronic liver disease or age >40 years. ## Why Supportive Care Is the Standard ```mermaid flowchart TD A[Acute HAV confirmed]:::outcome --> B{Synthetic function intact?}:::decision B -->|Yes| C[Supportive care, monitor]:::action B -->|No| D[ICU admission, consider transplant evaluation]:::urgent C --> E[Counsel on hygiene, fecal-oral precautions]:::action C --> F[Serial INR, albumin, mental status]:::action E --> G[Full recovery expected in 3-6 months]:::outcome ```
