HIV Flashcards
______: This is a retrovirus that attacks __________
Human Immunodeficiency Virus
CD4 T Lymphocytes
HIV may be transmitted through:
sexually,
blood transfusions,
sharing intravenous needles,
and from mother to child
PAGE 3-4
-
T/F Once CD4 counts become too high, host immune defences
cannot fight against opportunistic infections and
malignancies
F, low
CD4 count <200 =
AIDS Dx
Treatment of AIDS is focused on opportunistic infection
treatment and decreasing the HIV viral load through ________
Antiretroviral Therapy (ART)
Most HIV+ patients develop AIDS after ______ years if left
untreated
10
Undetectable = Untransmissible
-
Around 39 million people have died from HIV infection
Currently around 36.7 million living with HIV
There has been AIDS-defining efforts in the areas of education, prevention and research to decrease transmission and treat the virus.

RISK FACTORS
MSM,
unsafe sexual practices,
use of intravenous drugs,
vertical transmission, and
blood transfusions

PATHOPHYSIOLOGY
HIV attaches to host cells with _________ then the
virus then integrates its _________ material into that
of the host cell, taking over cell to generate more viral
proteins and genetic material. Eventually, the host cell
will die, and other CD4 cells will be infected.
Glycoproteins
Chromosomal
The number of CD4 cells within the affected individual
will fall by approximately _______ cells/uL per year WITHOUT the initiation of ART
50-80
With the addition of ART,__________ is now
the major cause of morbidity and mortality for HIV
patients.
Cardiovascular diseases
HX taking
Time of diagnosis
Complications/Opportunistic infections
Medications (ART)
Other comorbid illnesses
CD4 count and viral load
AFFECTED BODY SYSTEMS
CARDIAC
PULMONARY
OROPHARYNGEAL AND GI
CNS
ONCOLOGIC PROBLEMS AND HEMATOLOGIC SYSTEM
DERMATOLOGIC
T/F ART and HIV infection likely contribute to increased cardiovascular disease in patients
T
Common signs/symptoms of cardiovascular involvement:
Chest pain, SOB, fatigue
Jugular distension
Abnormal heart sounds
Pericarditis due to mycobacterium tuberculosis
PAGE 11
-
PULMONARY
Infectious diseases:
-URTI and acute bronchitis
Non-infectious diseases
-Kaposi’s sarcoma
-Non-Hodgkin’s Lymphoma
-Sarcoidosis
-Lung cancer
-Emphysema
For pulmnary sys., check for:
Signs of respiratory distress,
tachypnea,
cyanosis,
adventitious lung sounds
In the oro/GI system, HIV meds can cause:
pancreatitis,
hepatic steatosis, or
hepatotoxicity
*Hepatitis B or C co-infection
*Candida esophagitis and Cryptosporidium diarrhea
Assoc. symptoms for oro/GI system:
Nausea,
vomiting,
diarrhea,
constipation,
melena,
hematochezia, or
urinary symptoms
It is a very common manifestation of HIV infection
Candidia Esophagitis
FOR CNS, may include:
Meningitis,
focal demyelinating lesions,
malignancies from immunosuppresion
Pts with HIV affecting CNS will present c complaints of:
Altered mental status,
vision changes,
focalweakness,
seizures
Oncologic problems & Hematologic sys.:
-Anemia, thrombocytopenia, and leukemia
-Petechia or purpura
-Primary CNS lymphoma with Epstein Barr virus
ART and prophylactic medications can cause ________
Bone Marrow Toxicity
______patients will have concomitant infections
symptoms
Leukopenic
Hematologic problem that presents c weakness, fatigue, SOB
Anemia
PAGE 17
-
DERMATOLOGIC SYSTEM
Maculopapular or morbilliform rash
Oral ulcers or lesions
Molloscum contagiosum and HPV infections
Most common AIDS related cutaneous problem
Kaposi’s sarcoma
Kaposi’s Sarcome is a _______surrounded by violaceous
patches, nodules, or plaques
Vascular Neoplasm
PAGE 19-21

T/F Most patients with HIV will develop AIDS within 8 years if left untreated
F, 10
Asymptomatic phase: # of years: _______
~8 years
T/F If ART is started even after an initial diagnosis of AIDS,
the patient may live greater than 10 years
