Clinical Aspects of HIV Disease Kara Chew, M.D. Division of Infectious Diseases David Geffen School of Medicine at UCLA
Objectives Part I: Overview of clinical aspects of HIV infection and associated clinical disease • Acute infection • HIV Basics • Whirlwind tour of opportunistic infections in HIV/AIDS • Prevention of opportunistic infection Part II: Overview of occupational exposure risks and management for health care workers
Take Home Points 1) Every organ system is impacted by HIV infection 2) Best strategy is for PREVENTION of morbidity with timely diagnosis of HIV infection and antiretroviral therapy
The beginning: Acute Retroviral Syndrome (“acute HIV”) • Up to 80% of new HIV infections present with symptoms of viral illness, many misdiagnosed (influenza, infectious mononucleosis) • Fever, fatigue, rash, and headache • Lymphadenopathy, pharyngitis, myalgia, arthralgia, oral candidiasis • Nausea, vomiting, diarrhea; night sweats; oral ulcers • Duration of illness ranges from a few days to more than 10 weeks

Treatment regimens are much simpler today • Fixed-drug, multi-class combination pills (one pill once daily) • Tenofovir/emtricitabine/efavirenz • Elvitegravir/cobicistat/emtricitabine/tenofovir disoproxil fumarate • Emtricitabine/rilpivirine/tenofovir disoproxil fumarate • Once daily or twice daily regimens (3 pills once daily, 3 pills twice daily)
Goals of Treatment • Reduce HIV-associated morbidity and prolong the duration and quality of survival • Restore and preserve immunologic function • Maximally and durably suppress plasma HIV viral load • Prevent HIV transmission Panel on Antiretroviral Guidelines for Adults and Adolescents.
