A 32-year-old man from Mumbai presents with jaundice, dark urine, and abdominal discomfort for 5 days. He reports consuming contaminated water 3 weeks ago. On examination, he is afebrile with hepatomegaly and mild splenomegaly. Laboratory findings show ALT 2400 IU/L, AST 1800 IU/L, total bilirubin 8.2 mg/dL, INR 1.1, and albumin 3.8 g/dL. Anti-HAV IgM is positive. What is the most appropriate next step in management?

Explanation

## Clinical Context This patient has acute hepatitis A with typical presentation: recent contaminated water exposure, acute jaundice, marked transaminitis, and positive anti-HAV IgM. Coagulation profile (INR 1.1) and albumin remain normal — signs of preserved synthetic function. ## Management Approach for Acute Hepatitis A **Key Point:** Acute hepatitis A is a self-limiting illness in immunocompetent adults. Management is entirely **supportive**; no specific antiviral therapy is indicated. ### Rationale for Correct Answer **High-Yield:** The standard management of acute viral hepatitis A includes: 1. **Admission** — for monitoring and supportive care (especially if bilirubin >10 mg/dL or INR rising) 2. **Supportive measures** — hydration, nutritional support, rest 3. **Serial monitoring** — coagulation profile (INR, PT), bilirubin, albumin to detect fulminant hepatic failure 4. **Patient education** — strict hygiene, safe water practices to prevent transmission **Clinical Pearl:** In acute hepatitis A, fulminant hepatic failure (FHF) is rare in immunocompetent adults (~0.1–0.4%) but can occur; hence INR monitoring is essential. If INR rises or encephalopathy develops, transfer to a transplant centre becomes necessary. ## Why Each Distractor Is Wrong | Option | Reason | | --- | --- | | **Interferon-alpha therapy** | Antivirals (interferon, ribavirin) have NO role in acute hepatitis A. HAV is self-limiting and clears spontaneously in >95% of immunocompetent adults. Antivirals are not indicated and do not improve outcomes. | | **Liver biopsy** | Biopsy is contraindicated in acute hepatitis with normal INR and no suspicion of concurrent chronic liver disease. It carries bleeding risk and does not change acute management. Histology is not needed for diagnosis (serology suffices) or prognosis in uncomplicated acute HAV. | | **Corticosteroid therapy** | Steroids have no proven benefit in acute viral hepatitis and may increase viral replication and risk of secondary infection. They are not indicated unless there is autoimmune hepatitis (which is not the case here given positive anti-HAV IgM and acute presentation). | ## Key Monitoring Parameters **Warning:** Watch for signs of **fulminant hepatic failure**: - Rising INR (>1.5) - Falling albumin - Encephalopathy - Hypoglycaemia - Renal dysfunction If any develop → **urgent transfer to transplant centre**. **Mnemonic: SAFE Management of Acute Hepatitis A** - **S** — Supportive care (fluids, nutrition, rest) - **A** — Admit if bilirubin high or INR rising - **F** — Follow coagulation and liver synthetic function - **E** — Educate on hygiene and water safety
