|
|
|
virus component: Capsid
|
Outermost layer (cell wall)

|
|
|
HIV
|
from monkeys (simians), started as SIV.
Came from eating monkey. Transported to humans in about 1930’s (didn’t hear about it because Africa was undeveloped). Urbanization caused spread, same with prostitution. Earliest documented case was man who died in the 1950’s in Congo. In west, first case was Norwegian sailor in 1976 who had served in Africa in the 1930’s. In U. S. in 1981, from Canada to LA. Seen in male homosexuals. Retro virus. Classified as a lentivirus. Two strands of RNA that are identical. Reverse transcription. Has envelope and spikes. Receptor sites are found on helper T cells, on phagocyte cells and on nerve cells. Extended latent period. Formation of pro-virus during latent period (forms new cells but doesn’t leave host cell). Second stage – Forms latent virions Host cells replicating virus but remain in cell. Next stage is cell to cell fusion (moves cell to cell). Has high mutation rate because creating DNA from RNA. In asymptomatic people, its assumed virus mutates a million times a day. In AIDS patients it mutates one hundred million times a day. |
|
|
HIV stages, Category A
|
Person in asymptomatic or experiences lymphadenopathy
(swelling of the glands) |
|
|
HIV stage, Category B
|
Person starts to develop secondary infections. Lead to
Candide albieans which leads to thrush. Genital yeast infections and shingles will occur. On and off fever. A lot of G.I. problems |
|
|
HIV stage, Category C
|
AIDS Throat, bronchus and lungs. Other diseases will
occur such as CMU, TB, toxoplasmosis, pneumocytisis, carni pneumonia (most common cause of death in AIDS), Harposis sarcoma (most common cancer in AIDS) |
|
|
Second Classification of HIV, Group I
|
Acute illness, 50% of people who contract AIDS will develop
symptoms in 3 – 6 weeks. General symptoms, they will last a couple of weeks then go away. Are infectious during this stage. |
|
|
Second Classification of HIV. Group II
|
Asymptomatic infection.
Lasts months to years (no symptoms) 50% of people will develop AIDS in 7 – 10 years. Are infectious during this stage |
|
|
Second Classification of HIV. Group III
|
Generalize lympodenopathy
|
|
|
Second Classification of HIV, Group IV
|
Superimposed disease, AIDS
|
|
|
Third Classification of HIV – T-cell count
|
Normal T-cell count 800 – 1000 per cubic mm.
Below 200 is considered AIDS. There are at least 100 billion new viruses produced each day in a HIV patient. Most viruses form in T4-cells. A normal T4-cell should live several years, an infected T4-cell will live two days. |
|
|
Survival with HIV
|
About 5% of people who contract HIV are referred to as
long term non-progressors. Can go 20 – 25 years without progressing to AIDS. In a few cases virus is less virulent, but in most cases killer T-cells destroy helper T- cells before they replicate. Some people who are repeatedly exposed might have natural immunity. |
|
|
Testing for HIV
|
Checking for antibodies. Problem is long dormant period, most test can tell is 2 months after contracting disease.
There is a test to check for virus itself, in 48 hours, but it is expensive. Eliza is one type of test, faster results then Western blut test. |
|
|
Transmission of HIV
|
Direct contact with body fluids. Blood contain high
number, 1,000 and above. Semen contains low number, 10 to 100 viruses. Can live 6 hours outside a cell. Can cross placenta, contaminated needles, transfusions, transplants. Anal intercourse highest transmitter. Rare for oral to genital contract. Not spread by saliva, tears, sweat, casual contact, formites or vectors. World wide close to 3 million deaths. 50 million people infected. Leading cause of death in African countries. 16,000 new cases a day in Africa, almost all are heterosexual. In U.S. primary IV drug users and male homosexuals but heterosexual are gaining. Cannot develop vaccine, there are no subject to test on. |
|
|
Medications for HIV
|
To treat symptoms not cure the disease.
Popular drugs are AZT, ddI, ddC, they target reverse transcription, try to stop it. Protease inhibitors, works at cell level to stop host cell from producing protein. Interpheron has been used. Cocktail is at least 3 different medications |
|
|
Infants and AIDS
|

Common Secondary Infections Agents in AIDS
1. Pneumocystis carnii |
Protozoa– PCP. Leading infectious cause of death in AIDS.
Controversy over how to classify it. Recently been reclassified as a fungus (yeast). Ergosterol not present in fungal membrane. Cannot grow it in a culture. Used to be extremely rare but since AIDS it is more common. Don’t know what species it is. Close to 100% of children around the world have antibodies against it. Inhale it, then it goes dormant in your lungs unless you get AIDS. Can’t catch it from others. Aveli become inflamed. Lungs fill with mucus. Very aggressive combo of antibodies and sulfa drugs can save 50% of people who contract it. |
