A 20-year-old male who is a known IV drug user presents with jaundice, dark urine, and fatigue. Lab tests show elevated liver enzymes and a positive Hepatitis B core IgM antibody. What is the likely diagnosis and next steps?
These findings suggest an acute Hepatitis B infection. Acute Hepatitis B is usually self-limited and managed with supportive care, including rest, hydration, and avoidance of alcohol. However, this patient should be monitored closely for signs of acute liver failure, which, though rare, can occur. Harm reduction advice, including cessation of IV drug use and avoiding transmission to others, should also be emphasized.
