A 48-year-old man from Delhi with a 10-year history of alcohol use disorder presents with jaundice, ascites, and spider angiomas. He reports a recent episode of hematemesis. Laboratory investigations show: Total bilirubin 6.8 mg/dL, AST 320 IU/L, ALT 140 IU/L, ALP 220 IU/L, albumin 2.1 g/dL, PT-INR 2.8, platelet count 85,000/μL. Viral serology: HBsAg positive, anti-HBc IgM negative, anti-HBc IgG positive, HBeAg negative, anti-HBe positive, HBV DNA 2.5 × 10^4 IU/mL. Anti-HAV IgG positive, anti-HCV negative. What is the most likely diagnosis?

Explanation

## Diagnosis: Chronic Hepatitis B with Cirrhosis ### Serological Profile Interpretation | Marker | Result | Interpretation | |--------|--------|----------------| | HBsAg | Positive | Current HBV infection | | Anti-HBc IgM | Negative | NOT acute infection | | Anti-HBc IgG | Positive | Past or chronic infection | | HBeAg | Negative | Low viral replication (inactive phase or mutant) | | Anti-HBe | Positive | Consistent with inactive/low-replicative phase | | HBV DNA | 2.5 × 10^4 IU/mL | Moderate viremia (chronic, not acute) | **High-Yield:** Anti-HBc IgM is NEGATIVE, which excludes acute hepatitis B. The presence of anti-HBc IgG with HBsAg positive indicates chronic infection (≥6 months). ### Clinical Features of Cirrhosis **Key Point:** The constellation of jaundice, ascites, spider angiomas, hematemesis (variceal bleeding), thrombocytopenia, and coagulopathy (INR 2.8) indicates decompensated cirrhosis. **Mnemonic: Stigmata of Cirrhosis — ABCDEF** - **A**scites - **B**leeding (varices, coagulopathy) - **C**oagulopathy (elevated PT-INR) - **D**yspnea (hepatic hydrothorax) - **E**ncephalopathy - **F**etor hepaticus ### Laboratory Pattern **Clinical Pearl:** The AST > ALT ratio (320:140 ≈ 2.3:1) is typical of cirrhosis, especially in the setting of alcohol use. The markedly reduced albumin (2.1 g/dL) and elevated PT-INR reflect synthetic dysfunction. Thrombocytopenia (85,000/μL) suggests portal hypertension and splenic sequestration. ### Pathophysiology **Key Point:** Chronic hepatitis B (HBsAg-positive for >6 months) can progress to cirrhosis over 10–30 years, particularly in patients with concurrent alcohol use, which accelerates fibrosis. ### Distinction from Other Diagnoses 1. **NOT acute superinfection:** Anti-HBc IgM is negative (would be positive in acute infection). 2. **NOT acute alcoholic hepatitis alone:** HBsAg and anti-HBc IgG positivity indicate chronic HBV; acute alcoholic hepatitis does not cause these serological markers. 3. **HCC is possible but not the primary diagnosis:** While cirrhosis increases HCC risk, the presentation and labs are consistent with decompensated cirrhosis without specific HCC features (no mention of AFP, imaging findings, or mass). ### Management Considerations **High-Yield:** Patients with chronic hepatitis B and cirrhosis require: - Antiviral therapy (nucleos(t)ide analogues: entecavir, tenofovir) - Variceal prophylaxis / management (beta-blockers, endoscopic variceal ligation) - Ascites management (diuretics, sodium restriction) - Screening for HCC (6-monthly ultrasound + AFP) - Consideration for liver transplantation if decompensation progresses
