Cellular Immune Response
Immune Response
Human body has three means of defense
against bacteria, viruses or other
pathogens.
vPhagocytic immune response
vAntibody immune response
vCellular immune response
T lymphocytes (T-cells)
Killer T Cells
Helper T-Cells (CD4)

Suppressor T-Cells
Pathophysiology of HIV infection
Pathophysiology of HIV-1
Retrovirus carries genetic material in
RNA
1. HIV retrovirus attaches to the uninfected

CD4 cell.
2. Copies the RNA into cells DNA.
3. New viral particles bud from this cell and
begin the process all over again.
CD4+T cell count determines degree

of immune suppression

Origin of HIV in the

United States
HIV first appeared in 1981 in San
Francisco among homosexual men. It
is now believed that the virus
entered the US in the early 1970s
HIV/ AIDS today in the

United States
Prevalence of AIDS in the US
More than 1.2 million people in the United States

are living with HIV infection, and almost 1 in 8
(12.8%) are unaware of their infection.
Gay, bisexual, and other men who have sex with men
(MSMa), particularly young black/African American
MSM, are most seriously affected by HIV.
By race, blacks/African Americans face the most
severe burden of HIV.
11
33.410 HIV
In 1981, there were 291 reported cases

By 1995, there were 74,180 new cases.
1981-2000: 753,000 cases in the US
438,000 Deaths
2014- CDC estimates that 1,218,400 persons aged

13 years and older are living with HIV infection,
including 156,300 (12.8%) who are unaware of their
infection
12
HIV as a Global epidemic
THE AIDS PANDEMIC
According to estimates by WHO and

UNAIDS, 36.9 million people were living with
HIV globally at the end of 2014. That same
year, some 2 million people became newly
infected, and 1.2 million died of AIDSrelated causes..

Classification of AIDS
CD4+T cell count determines
degree of immune suppression.
AIDS is defined as clinical
category and those in categories
A3 and B3 and all of category C.

Exposure Category of HIV
The time from initial infection to the

development of AIDS ranges from months to
years depending on:
How HIV was acquired
Personal factors
Therapeutic intervention
Men who have sex with men

IV drug users
Male homosexuals who
also inject drugs
Hemophiliacs
Heterosexual contact
Recipient of blood transfusion

Transmission
Saliva, Tears, and Sweat
Any body fluid that contains HIV-1 or

CD4+
T lymphocytes
HIV has been found in saliva and tears in

very low quantities from some AIDS
patients.
Contact with saliva, tears, or sweat has
never been shown to result in
transmission of HIV.
Blood
Serum
Seminal fluid
Vaginal secretions, amniotic fluid
Breast milk
fluid surrounding the brain and the spinal cord
fluid surrounding bone joints

Stages of Infection
Post exposure prophylaxis

All health care providers who have
sustained a significant exposure:
AZT, Epivir, 3TC (reverse transcriptase

inhibitors)
Viracept, Crixivan (protease inhibitors)
Within 72 hours after exposure
For 4 weeks post exposure
25
EIA- Enzyme-Linked Immuno-
(ELISA)
Western blot assay

CD4/CD8 Counts
Lymphocyte Counts
OraQuick- In home HIV test
27
Nucleoside Reverse Transcriptase Inhibitors

(NRTIs)
Zidovudine (AZT) Retrovir
There are many treatments now that can help people with
HIV. As a result, many people with HIV are living much
longer and healthier lives than before.
Currently, medicines can slow the growth of the virus or stop
it from making copies of itself. Although these drugs don't
eliminate the virus from the body, they keep the amount of
virus in the blood low. The amount of virus in the blood is
called the viral load, and it can be measured by a test.
Non-nucleoside Reverse Transcriptase Inhibitors

(NNRTIs)
Efavirenz (EFV) Sustiva
Delavirdine (DLV) Rescriptor
33.410 HIV
Used to track the response to treatment for

HIV infection
Used to detect HIV infection before the
development of antibodies
Used to screen neonates
A better predictor of disease progression
than the CD4 count
The lower the viral load, the longer the
time to AIDs diagnosis & the longer the
survival time.

Taking the Drugs
Cost of HIV Medications
HIV medicines have become much easier to take in recent

years. Some newer drug combinations package 3 separate
medicines into only 1 pill, taken once a day, with minimal side
effects.
For the great majority of people, HIV medicines are
tolerable and effective, and let people infected with HIV live
longer and healthier lives.
Still, for some people taking medicine for HIV can be
complicated. Some of the drugs are difficult to take, can
cause serious side effects, and don't work for everyone.
Even when a drug does help a particular person, it may
become less effective over time or stop working altogether.

b. Decreased serum
globulin level
c. Increased serum
hemoglobin level
d. Increased number
of T-Helper cells
A client with HIV is receiving antiviral agent

zidovudine. What laboratory studies need to be
monitored in the client receiving this medication?
A Client with HIV has been hospitalized. During your

initial assessment of the client, you observe cheesylooking white patches in the clients mouth. When the
patches are rubbed, erythema and bleeding occur. You
suspect:
a. Serum glutamic-pyruvic
transaminase
b. BUN
c. Erythrocyte
sedimentation rate
d. Red blood cell count
A. Herpes simplex
B. Candidiasis
C. Leukoplakia
D. Karposis Sarcoma
The client with HIV has begun therapy with

zidovudine (AZT, Retrovir). The nurse carefully
monitors which of the following laboratory results
The client exposed to HIV about 3 months ago has

seroconverted to an HIV positive status. The nurse
anticipates that the client will experience which of
the following at this time?
a.
b.
c.
d.
during treatment with this medication?
a. Complete blood
count
b. BUN
c. Blood culture
d. Blood glucose level
Oral lesions
Purplish skin lesions
Chronic cough
No signs or
symptoms
Does person with HIV infection

have to be treated for the rest
of their life?
Right now, there is no cure for HIV infection
or AIDS. So, once one starts treatment, they
have to continue to be sure the virus doesn't
multiply out of control.
59
33.410 HIV
I am a nurse who was exposed to vomit or sputum

from an end stage AIDS patient which contacted a
small area of non-intact skin (less than 1 cm) on my
finger. What is the risk of infection from this
incident?
There is no evidence of a health care worker getting
infected with HIV through contact with vomit or
sputum. The real risk for transmission is partly
determined by the presence of blood in the vomit or
sputum; otherwise, those fluids only pose a
theoretical risk for infection. Given the fact that
these fluids also came into contact with a small area
of nonintact skin, your risk for infection is quite
small.
