HIV/AIDS | Pathophysiology, Diagnosis & Disease Progression

Ninja Nerds!
In this episode of the Ninja Nerd Podcast, Zach and Rob walk you through a high-yield, case-based approach to HIV/AIDS, focusing on how HIV infects the immune system, progresses through its clinical stages, and ultimately leads to acquired immunodeficiency syndrome (AIDS). This episode builds the foundation you need before diving into opportunistic infections and antiretroviral therapy.
We start with the fundamentals of HIV, breaking down viral structure, transmission, and the HIV life cycle. From there, we explain how the virus targets CD4+ T cells, the roles of CCR5 and CXCR4, and how progressive immune dysfunction develops over time. We also walk through the transition from acute retroviral syndrome to chronic HIV infection and eventually AIDS, emphasizing the changes in viral load, CD4 count, and immune responses throughout each stage.
Next, we focus on the diagnostic approach, including fourth-generation HIV testing, confirmatory testing, viral load measurement, and CD4 monitoring. Along the way, we highlight key clinical findings that help distinguish acute HIV from other infectious syndromes and explain how laboratory testing changes throughout the course of infection.
This episode provides the essential framework for understanding HIV pathophysiology and diagnosis, setting the stage for our next discussions on AIDS-defining illnesses, opportunistic infections, and antiretroviral therapy.
Let’s get into it, Ninja Nerds!
