Intro to HIV Flashcards
How is HIV transmitted
Sexual contact Injection drug use Pregnancy, childbirth, and breast feeing Occupational exposure Blood transfusion/organ transplant
2 important proteins in the HIV structure
Gp 120 (docking protein) p24 (capsid protein)
3 critical enzymes for HIV lifecycle
Reverse transcriptase
Integrase
Protease
What are 3 symptoms/diseases you get with a CD4 count
- Under 500
- Under 200
- Under 100
- Under 50
- Weight loss, herpes zoster, lymphadenopathy
- Pneumocystic pneumonia, TB, esophageal candidiasis
- CNS lymphoma, cryptococcal meningitis, extra-pulmonary TB

3 reasons why you want to reduce viral replication
Restore and preserve immune function
Reduce HIV transmission
Reduce chronic inflammation and its consequences
ART should include what drugs?
2 NRTIs
And 1 either NNRTI, protease inhibitor, or integrase inhibitor
Pre-Exposure prophylaxis
Tenofovir/Emtricitabine
1 tablet daily for HIV negative people
For high risk people
Main side effect is nephrotoxicity
90-90-90 goal
90% of all people living with HIV will know their status
90% of all living with HIV will receive ART
90% of all receiving ART will have viral suppression
This will allow us to end the AIDS epidemic by 2030
2 theoretical ways to cure HIV
Viral eradication
Viral remission
Viral eradication methods to cure HIV
Reverse latency and destroy the reservoir
Bone marrow transplants from someone with immunity
Gene therapy
