2025 Step & Shelf Update: New HIV Treatment
HIV is a top-10 high-yield topic for Step & Shelf exams, and there's a new first-line treatment you need to know in 2025. Here's the simplified guideline:
What's IN
- Integrase inhibitor-based regimens are now the clear first-line choice for most patients starting HIV therapy.
- These typically combine:
- One integrase inhibitor (e.g., bictegravir or dolutegravir)
- Two nucleoside reverse transcriptase inhibitors (NRTIs, e.g., tenofovir + emtricitabine)
- In some cases, a simplified two-drug integrase-based regimen (dolutegravir + lamivudine) is acceptable, but avoid if:
- Very high viral load (>500,000 copies/mL)
- Hepatitis B coinfection
- Starting therapy before resistance test results are available
What's OUT
Regimens based on:
- Protease inhibitors (e.g., atazanavir)
- Non-nucleoside reverse transcriptase inhibitors (NNRTIs, e.g., efavirenz)
- Older integrase inhibitors (raltegravir, elvitegravir)
These are out due to:
- Higher risk of resistance
- More side effects and drug interactions
- Higher pill burden and less convenience
Bottom line: When in doubt, pick an integrase inhibitor-based regimen for first-line HIV treatment questions!
P.S. HIV treatment is super nuanced. Tons of caveats (e.g. standard integrase inhibitor-based regimens are risky in patients who have taken long-acting cabotegravir as PrEP). If you need extra practice, Ora has over 500 HIV questions so you can study the details until you feel confident!
