HIV AIDS
What it stands for
Human Immunodeficiency Virus
Acquired ImmunoDeficiency
Syndrome
What it is A virus: an agent that replicates inside a living cell
A syndrome: a collection of multiple symptoms or characteristics that often occur together
How it is diagnosed
A test that shows HIV antibodies or antigens in a person’s blood or saliva
• HIV positive test • A T- Cell count of < 200 -OR-• 1 or more opportunistic
infections
![Page 7: NURS 330 - Schedule for 4/28/14 HIV Lecture – Disly Juarez, MPH Return and Review Quiz Group Activity Distribute Study Guide for 5/5/14 Mid-term In-Class](https://reader036.vdocuments.site/reader036/viewer/2022062516/56649db15503460f94aa036c/html5/thumbnails/7.jpg)
AIDS Criteria (CDC)HIV positive test AND a T-Cell count of <200 or 14%
(healthy T-Cell count ranges from 800-1200)
ORHIV positive test AND one or more opportunistic infections
(OIs)/certain cancers
7
If the T-Cell count goes up, or the opportunistic infection goes away, does the
person still have AIDS?
YES

HIV & the Immune System
HIV attacks the T cells (aka CD4 cells) weakening the immune system
Over time HIV can lead to AIDS

STDs and HIV
STDs increase the
concentration of “infection
fighting” CD4 cells in genital secretions, a
favorite target of HIV
STDs cause breaks in the skin on and
surrounding the penis, vagina and
anus, which provides a
perfect entry way for HIV
STD infection increases risk of contracting HIV (susceptibility)

HIV+ individuals who are also
infected with an STD have more
HIV in their genital
secretions

STDs and HIV
HIV+ men who are also infected with an STD have much more HIV in their semen than
HIV+ men without an STD
STD infection increases risk of passing HIV to a partner (infectiousness)

California’s “Willful Exposure” Law (1998)aka “Recalcitrant Behavior”:
Willfully exposing another to HIV through unprotected sex 8 years of imprisonment Intention to infect others with HIV through sex
To be prosecuted under the law, one would have to do ALL of the following: Have anal or vaginal sex Know that they are HIV + Fail to disclose their HIV status Fail to use a condom Have a specific intent to infect another person
Actual knowledge of HIV infection without more evidence of “specific intent” is insufficient for prosecution.

TREATMENTWhat are Anti-retrovirals (ARVs) ?
• Anti-retrovirals are drugs that interrupt the HIV replication process and help preserve the health of the immune system
• These drugs must be taken in combinations in order to have a lasting effect. The three drug combination is commonly known as a “triple cocktail”
• Using a combination of anti-retrovirals creates multiple obstacles to HIV replication. This is designed to keep the virus from replicating freely and reduce the possibility of a mutation.

When to start anti-HIV medications?
2 schools of thought:
1.Treatment should begin if there are severe symptoms of HIV infection or a diagnosis of AIDS with a CD4 count of 350 cells/mm3 or less
2.Starting treatment immediately following diagnosis
Because of the complexity of selecting and following a regimen, the severity of the side-effects, and the importance of compliance to prevent resistance, it is extremely important to engage patients in treatment decisions. 46
