Congenital disorders are NOT all genetic
What are the manifestations of the initial/primary HIV
fever, fatigue, muscle pain, weakness, sore throat, night sweats, GI problems, swollen lymph nodes, macular/papular rash, headache, malaise
What happens in the Initial/ Primary period of HIV
Rapid viral replication
What is the possible test result at the initial/ primary period?
Test may come back negative at this point
What is the normal T- helper count?
800-1,000
What is the T helper count at initial/ primary period?
Less than 500
What happens during latency period?
No signs and symptoms
Up to 10 years
What is the CD4 count at latency period?
CD4 counts between 200-499
What is the CD4 count when a person has AIDS?
Less than 200
What are present in chronic inflammation
interferons
What produce interferons
T cells
What are the differents types of interferons
alpha
beta
gamma
What does IL-1 do
recruits neutrophils
activates inflammation
induces fever
What produces IL-1
activated macrophages
neutrophils
endothelial and epithelial cells
What does IL-4 do
promotes T, B, and mast cells survival
part of responses that involve eosinophils
What antibody is IL-4 related to
IgE
What produces IL-4
CD4 T helper cells
mast cells
What does IL-6 do
involved in acute inflammation- therefore CRP levels to increase
causes fever
stimulate neutrophil production
What produces IL-6
macrophages
T cells
endothelial cells
Tumor necrosis factor alpha
induces fever
seen in acute inflammation
stimulates NK cells to cause apoptosis
activates neutrophil and endothelial cells
What produce Tumor necrosis factor alpha
macrophages
T cells
mast cells
What are the consequences of AIDS
Risk of opportunistic infection, immune system compromised, wasting syndrome, metabolic disorders, malignancies
