What kills people living with HIV?

NA-ACCORD: Smoking, HTN & Cholesterol Contribute to MI risk in HIV Infection

Smoking

• shortens life span of people with HIV by 6 yr

• far more harmful than well managed HIV itself

HTN

• Major risk factor ‐ CAD 

Hypercholesterolemia

• ASCVD score

• Statin use

What is U=U?

Page 17: HIV Well Into the 21st Century - Creighton University...4/26/2019 1 HIV Well Into the 21st Century Manasa Velagapudi, MBBS Assistant Professor Division of Infectious Diseases CHI Health

Why Is U=U Important

• Knowing U=U can be transformative for people living with HIV (PLWH) & their interpersonal relationships

• Affirms they are not disease vectors & can be touched and loved

• Many PLWH still face both institutional & personal stigma , discrimination

• As a result, many avoid relationships, sexual or otherwise, because of their perceived potential to transmit HIV

Talk to Your Patients about U=U

• Counsel on the necessity of staying undetectable for U=U to work

• Educate on the importance of taking HIV medications every day to stay healthy and also prevent transmission to their sexual partners

• Explain and reinforce that when the virus is suppressed, they will not transmit HIV to partners

• Encourage patients to know their viral load by keeping their medical appointments so they and their partners are sure of their undetectable status

Despite Extraordinary Efficacy, HIV Therapy Can Be Improved

ART approaches under current investigation include:

Virologic suppression rates can barely be improved in adherent patients

But there is room to improve ART:

• Short‐term and long‐term safety

• Tolerability

• Convenience

• Cost

• Activity against panresistantvirus

• Still no available cure

What is PrEP?
