question | answer |
---|---|
order of infection of cell by HIV virus | viral attachment -> viral penetration/fusion -> uncoating -> reverse transcriptase -> integration -> viral latency and protein synthesis -> cleavage and viral assembly -> budding...starts all over again |
s+sx of acute retroviral syndrome | can be asymptomatic to flu-like symptoms 2-6 weeks post infection |
s+sx of chronic HIV infection | may be asymptomatic, but may also have enlarged lymph nodes, lack of energy, weight loss, frequent fever and night sweats, persistent or frequent yeast infections, persistent skin rashes/flaky skin, short-term memory loss, frequent severe herpes infection |
AIDS infection | CD4 <200 and opportunistic infection |
s+sx of AIDS infection | coughing/SOB, seizures/lack of coordination, confusion/forgetfulness, severe persistent diarrhea, fever, weight loss, N+V, abdominal cramping, weight loss and extreme fatigue, severe headache, coma |
if western blot postive | HIV positive status |
risk factors | aboriginal people in Canada, injection drug users, MSM, sexual transmission (vaginal, anal, oral), infected blood, accidental needle stick, mother to child transmission in pregnancy or through breastmilk |
virulogic failure | HIV still detectable in blood 48 weeks after starting treatment or is detected again after viral load was undetectable |
immunologic failure | CD4 decreases further or does not increase within 1st year of therapy |
clinical failure | opportunistic infection or decline in health after at least 3 months on ARV therapy |
nucleoside reverse transcriptase inhibitor | contains faulty imitation of T-cells nucleotides which prevents formation of the double strand DNA |
non-nucleoside reverse transcriptase inhibitor | attach to the reverse transcriptase enzyme preventing it from functioning |
protease inhibitors | binds to protease enzyme and prevents separation of substances |
ABCD of HIV | Abstinence, Be faithful, Condom, Disclosure of HIV status |
average person living with HIV | a "she" with 3-4 children lives in africa and has a poor life expectancy |
