Hepatitis B
Notes de l’épisode
Ninja Nerds!
In this episode of the Ninja Nerd Podcast, Zach and Rob walk you through a high-yield, case-based approach to Hepatitis B, focusing on how to recognize acute versus chronic infection, interpret serologies, and make the right clinical decisions on exams and in practice. This is one of the most testable topics in infectious diseases because it blends clinical medicine with pattern recognition and lab interpretation.
We start with a classic case of acute Hepatitis B, highlighting key clues like rash and arthralgia that help distinguish it from other causes of acute hepatitis. From there, we break down the step-by-step workup, including confirming hepatocellular injury, ruling out obstruction, and using the HBV triple panel to make the diagnosis. You will also learn high-yield concepts like the window period and when supportive care is appropriate versus when escalation is needed. 
Next, we shift to chronic Hepatitis B using an asymptomatic patient scenario, focusing on screening, risk factors such as perinatal transmission, and how to interpret serologies indicating chronic infection. We then walk through staging with HBeAg and HBV DNA, and clarify when to initiate antiviral therapy, along with the importance of long-term monitoring and hepatocellular carcinoma surveillance. 
We close with rapid, high-yield concepts including major complications, hepatitis D superinfection, and prevention strategies such as vaccination and post-exposure prophylaxis. This episode provides a clear, practical framework for confidently approaching Hepatitis B from diagnosis to management.
Let’s get into it, Ninja Nerds!
