ABOUT THE VIRUS
What is HIV/AIDS?
HIV stands for Human Immunodeficiency
Virus. It is the name given to the virus that causes AIDS.
AIDS stands for Acquired ImmunoDeficiency Syndrome.
It is the name given to a set of defined symptoms caused by the virus.
The difference between the two is this simple:
HIV is what you catch and transmit. HIV is the virus that effects your Immune
system.
AIDS is a Doctors diagnosis based on current medical and government data
defining a set of symptoms caused by HIV.
What is the most common way of getting HIV?
Your blood stream coming in contact with any of the
four fluids (Blood, semen, vaginal fluids, and breast milk) that can transmit
HIV.
The most common methods for this to happen are:
Unprotected sex
Sharing of needles
Breast feeding
For more information on the transmission of the virus and ways to protect yourself, Check out HIV/AIDS Education and the Guide to Risk Activities.
How do they monitor it's progress?
HIV is monitored in many ways. The two
most used methods now are two blood tests used comparatively.
The first test monitors T-Cells, or CD4 cells. They are a specific white cell in
your immune system. The lower they are the weaker your immune system is.
The second test is called a Viral Load. This is the newest test, which actually
counts active virus in the blood stream. The higher the viral load, the more
active the virus is.
Doctors use these tests together to monitor the progress of the virus and
determine if medications are working or not.
What is a T-Cell?
Okay, here is a very simplistic overview of what a T-Cell
is.
A T-Cell (also known by different names depending on the test you get) is a
specific kind of white blood cell in your immune system that is attacked by the
virus. It is kind of the 'General' of the army. It is what tells the rest of the
immune system what to do - what foreign agents to attack. With out the T-Cell
the rest of the immune system just doesn't know what to do.
This is why it is used as a monitor for how badly the immune system has been
compromised by HIV (and often in other conditions that compromise the immune
system - like chemotherapy).
In a normal system there should be about 700 to 1000 T-Cells. 500 is considered
the low end of 'normal'. Below that Dr.'s begin to worry. The amount of T-Cells
can vary in a system from hour to hour if you test it that often. They are only
a loose indicator - which is why the Viral Load test became so useful (Viral
Load test actually tells how much of the virus is active in the system).
When someone is telling you about their blood work, remember: T-Cell count - Up
(more generals to direct the army) Viral Load - Down (less of the enemy).
What physically happens (that you can see) to your body?
Nothing.
There are no physical (or mental) symptoms that are specific to HIV or AIDS.
Your body will look the same with or without HIV or AIDS.
There are no physical symptoms that you can feel. You don't get a fever or
headaches and you don't feel sick. It is possible to live your whole life with
HIV and not know it. Only an HIV anti-bodies test can tell if you have the
virus.
The virus effects your immune system. This is something that you can't see or
feel directly. As your immune system weakens, opportunistic diseases will take
advantage of your body; these are the symptoms that manifest physically on the
body. These are the symptoms of the Opportunistic infection - NOT HIV/AIDS.
How long does it take before you know you have the disease?
Right after that test comes back Positive (the second time), you know.
There are no physical symptoms of the HIV virus. You can't tell that you have it
until you have had the test. You can suspect you have it, or fear
you have it, or think you have it - but you don't know
you have it until you have had the test.
Just as you can't tell someone else has it by looking at them - you can't tell
you have it by looking at yourself or judging by the way you feel.
Example - Some people will develop flu like symptoms as the virus
initially establishes itself in the body. Not all people do. How many times have
you had the flu and not been HIV Positive?
Semantics - No one has ever died or gotten sick from AIDS/HIV.
They die or get sick from the complications arising from the opportunistic
infections taking advantage of what HIV does to the immune system.
To answer the question directly - indefinitely. Without a test
you could live your whole life without knowing you have the virus. You just
won't know why you couldn't recover from the accident or disease.
What are the steps a person goes through in the process of getting AIDS?
You engage in a risk activity.
You acquire the virus.
Your immune system becomes weaker, until you fit some medical criteria for AIDS.
These are the only absolute givens. Everything else is a variable.
The HIV/AIDS virus effects persons in as individual a way as there are
individuals. This is one of the reasons HIV is a very personal thing. One
persons experience with the virus is not the same as the next persons. Infected
in different ways, find out in different ways, deal with it differently,
different incubation periods, different medical regiments, different
opportunistic infections, different complications. It's all similar, but
different. As unique as you are.
Here is a HIV/AIDS time line that will show just how different the range of
infection can be.
It works like all viruses, but here are some specifics. (This may get a little technical, but I have tried to keep it as simple as possible.)
(All Viruses)
Regardless of the type of host cell, all viruses follow the same basic steps in
what is known as the lytic cycle:
Those viruses that do not enter the cell must inject their contents (genetic instructions, enzymes) into the host cell. Those viruses that dissolve into a cell simply release their contents once inside the host. In either case, the results are the same.
Once inside the cell, the viral enzymes take over those enzymes of the host cell and begin making making copies of the viral genetic instructions and new viral proteins using the virus's genetic instructions and the cell's enzyme machinery. The new copies of the viral genetic instructions are packaged inside the new protein coats to make new viruses.
Once the new viruses are made, they leave the host cell in one of two ways:
(HIV specifics)
There are many kinds of viruses, for example the hepatitis viruses that
infect liver cells and cause hepatitis, or the herpes viruses that infect nerve
cells and cause herpes, and HIV which infects the immune system.
The immune system will produce anti-bodies to any virus. Each anti-body is
specific (there is a different one for measles, hepatitis, and HIV - see
TESTS) and allows the immune system to track down viruses and destroy them.
In the case of HIV, it infects the immune system, thus the immune system begins
to fight itself.
HIV is a Retrovirus
HIV belongs to a class of viruses called retroviruses, which have genes
composed of ribonucleic acid (RNA) molecules. In contrast,
the genes of humans and almost all other organisms are made of a related
molecule, deoxyribonucleic acid (DNA) .
Like all viruses, HIV can replicate only inside cells-- commandeering the cell's
machinery to reproduce. However, only HIV and other retroviruses use
an enzyme called reverse transcriptase to convert their RNA into DNA,
which can be incorporated into the host cell's genes. Since only
retroviruses use this enzyme (i.e., and it is not used by the host cell),
treatment strategies have focused heavily on this enzyme.
Structure of HIV
The viral envelope. HIV has a diameter of 1/10,000 of a
millimeter and is spherical in shape. The outer coat of the virus, known as the
viral envelope, is composed of two layers of fatty molecules called
lipids. These lipids actually come from the membrane of a
human cell when a newly formed virus particle buds from the cell.
Embedded in the viral envelope are proteins from the host cell together with
copies of a complex HIV protein that protrudes from the envelope surface.
This Envelope protein, known as Env, consists of a cap and a
stem that anchors the structure in the viral envelope. Much of the
research to develop a vaccine against HIV has focused on portion of this complex
envelope protein.
The viral core (or capsid). Within the envelope of a mature
HIV particle is a bullet-shaped core made of 2000 copies of another viral
protein (p24.) The core surrounds two single strands of HIV RNA,
each of which has a copy of the virus's nine genes.
The core of HIV also includes another protein (p7), the HIV nucleocapsid
protein; and three enzymes that carry out later steps in the virus's life cycle:
reverse transcriptase, integrase and protease.
Steps
in Viral Replication
The replication of HIV within the body occurs in a predictable sequence of nine
steps:
Now in the case of HIV, the immune system is producing new virus and fighting itself.
Why is it so hard to find a cure?
First, viruses have no cure. Not even the
common cold virus. In the case of the common cold, the virus is in cells that
can be found and destroyed by the immune system. HIV is using the immune system
to reproduce.
Because of the way a virus works (See how the virus
works), it will be difficult to ever find a cure.
A cure would entail finding something that could identify the specific DNA or
RNA in the host cell that belonged to the virus (which is now wound up in our
own DNA) and cut it free or eliminate it while leaving the DNA of the host in
tact.
Vaccines, which would prevent the virus from ever replicating in the body, are
in the works. This would prevent any new infections, but not 'cure' the people
that already have the virus.
Does having HIV/AIDS limit what you can do physically?
HIV - No, not really. It will depend on the
person, but in general with HIV the person looks and feels healthy in all
respects and can do anything that he or she did before. There is also nothing
that says they can't get better then they were either (for example, if you are
an athlete training for an event, you can still run faster with practice or get
stronger).
AIDS - This is a medical diagnosis of how far the immune system as been
compromised. Since it also includes having been subject to an Opportunistic
Infection, it is possible that there are now physical limits to the things you
can do. What is limited depends on the Opportunistic Infection and how well the
patient recovers.
No.
The H in HIV stands for HUMAN, and tells us that the virus ONLY effects Humans.
There are related strains of the virus in Animals, but they do NOT cross species.
Related strains would include SIV (Simian Immune Deficiency
Virus - effecting Primates) FIV (Feline Immune Deficiency Virus - effecting
Cats) EIAV (Equine Infectious Anemia Virus - effecting Horses) BIV (or BIDV
Bovine Immune Deficiency Virus - effecting Cows), CAEV (Caprine
arthritis-encephalitis virus - effecting Sheep and Goats)
ABOUT THE MEDICATIONS
I read something about Medications they are using to fight AIDS. Could you explain what they are and how they are working?
The drugs used to fight HIV/AIDS are called Antiretrovirals (Anti-retro-virals : It's a mouth full - and it gets worse). These drugs fall into three different categories, depending on how they work.
Nucleoside Reverse Transcriptase Inhibitors (Nucleoside Analogs or
"Nukes")
This drug mimics one or more components of the HIV's DNA or RNA and interrupts
the viral replication process. They work by blocking the reverse Transcriptase
enzyme essential for viral replication. This terminates the viral DNA chain,
halting the replication process before it is completed.
Protease Inhibitors (PI's)
These drugs block the process by which HIV reassembles itself inside a cell.
Specifically, these drugs disable protease, an enzyme that is necessary for
cutting large viral peptides into smaller, functional units, in order to create
active, new viral particles. The resulting virus is defective and not
infectious.
Non-Nucleoside Reverse Transcriptase Inhibitors (NNRTI or 'nerts')
Like the nucleoside analogs, this class of drugs inhibit HIV replication by
interfering with the reverse Transcriptase enzyme for viral replication. These
drugs have a different mechanism of action and a distinct side effect profile
from the other drugs.
The 'cocktail' is a combination of at least two drugs (preferably from different groups) to help stop the replication of the virus in as many places as possible.
Is it true that with the weakened immune system (AIDS) patients can't tolerate the meds and it won't do them any good?
No.
The question really boils down to a patient / Doctor decision on whether the
risks (or side effects) outweighs the benefits (of stopping or slowing the
virus's progression). This question is relevant in any stage of the disease.
Many do not tolerate or react well to the medications - others do. Some have
severe side effects - others don't.
Patients and Doctors need to communicate their desires and tolerances in the
debate of Quality vs. Quantity of life. This is what will determine whether the
medications are doing them any good.
What are the side effects of the medications out there? Can they be helped with vitamins?
The side effects range from headaches to nerve damage, and it varies from
person to person. Different drugs react differently in different people. Some
people have no side effects - some have all the side effects - some only have
one or two of them and in different degrees of severity.
The most common are - (in no particular order)
headaches, nausea, diarrhea, upset stomachs, appetite loss, rashes, gas, rashes,
fatigue, insomnia, vomiting, dizziness, drowsiness, fevers.
Mental side effects - anxiety, confusion, depression, inability to concentrate,
nightmares, paranoia, more rarely: suicidal tendencies (most of these are only
associated with the drug Sustiva, but others have displayed them)
Some of the more rare and sever side effects can be - Kidney stones, elevated
liver enzymes, hair loss, peripheral neuropathy, anemia, muscle loss (or
'wasting syndrome'), unexplained pains, pancreatitis, liver inflammation.
Long term side effects - Changes in blood sugar levels (development of
Diabetes), changes in fat levels and how the body stores it, bone marrow
suppression, damage to mitochondria, fluctuations in red and white blood cell
counts, lactic acidosis (which can cause liver and kidney failure), pancreatitis.
Can they be helped with vitamins?
Maybe - Once again - like these drugs, different things react differently in
different people.
The only symptom that I have tried to alter with vitamins and diet was diarrhea
- I had no luck. It didn't matter what I ate, drank, or how much anti-diarrheals
I took, I had diarrhea until I stopped taking the medication. In fact, it only
took 24 hours for the diarrhea to stop after the ceasing of the medication.
All of this information can be gotten from the drug manufactures, the
pharmacist, magazines, and on the web. Specific drugs have specific side effects
- this is a run down of the most common from them all.
Could you be more specific about which drugs cause which side effects?
Yes I can, with the help of a Chart Published in POZ magazine.
(PI's) Protease Inhibitors - This class of drug blocks the process in which HIV reassembles itself inside a cell. Specifically, they block Protease, and enzyme necessary for cutting viral peptides into smaller, functional units, in order to create new active viral particles.
| Agenerase (amprenavir) | Diarrhea, nausea, oral tingling and numbness, rash, vomiting. | Long term side effects : Changes in blood sugar levels (and potentially development of diabetes), elevations in blood fat levels, and changes in the way the body stores fat (including development of fat deposits in the abdomen and on the back of the shoulders, breasts and limbs, as well as loss of fat in the arms, buttocks, legs and face). |
| Crixivan (indinavir) | Anxiety, back pain, diarrhea, headache, insomnia, kidney stones, nausea, rash, stomach upset, vomiting. | |
| Fortovase (saquinavir) | Diarrhea, elevated liver enzymes, headache, insomnia, nausea, stomach upset. | |
| Norvir (ritonavir) | Appetite loss, diarrhea, elevated liver enzymes, nausea, oral tingling and numbness, stomach upset, vomiting. | |
| Kaletra (lopinavir and ritonavir) | (See Norvir, and), headache, vomiting, stomach pain, weakness, rash, abnormal bowel movements. | |
| Viracept (nelfinavir) | Diarrhea, elevated liver enzymes, gas, nausea, rash, stomach upset. |
(NRTIS or 'Nukes') Nucleoside Reverse Transcriptase Inhibitors - This class of drug mimics one or more of the components of HIV DNA or RNA interrupting the viral replication process. Specifically, it blocks the reverse transcriptase enzyme, inserting a nucleoside analog into the new viral DNA strand which terminates the replication process before it is complete.
| Retrovir (AZT) | Appetite loss, fatigue, headache, nausea, stomach upset: more rarely: anemia, muscle loss, pain | Long term side effects : bone marrow suppression and damage to the mitochondria (the cell's energy source). These effects may cause low red and white blood cell counts, muscle pain and loss (particularly in the arms, buttocks and legs - often referred to as 'wasting'), fatigue and peripheral neuropathy. More rarely: lactic acidosis (which can cause liver and kidney failure and death) and pancreatitis. |
| Epivir (3TC) | Hair loss, nausea | |
| Combivir (AZT+3TC) | See Epivir (3TC) and Retrovir (AZT) |
|
| Hivid (ddC) | Mouth ulcers, nausea, peripheral neuropathy | |
| Videx (ddI) | Diarrhea, nausea, peripheral neuropathy; more rarely: pancreatitis | |
| Ziagen (abacavir) | Serious allergic reaction*, appetite loss, diarrhea,
insomnia, nausea, vomiting *Serious allergic reaction - resembles the flu - Call your Doctor immediately to determine if it is the allergic reaction - and follow Dr's instructions. Do not do this on your own! Do not stop taking the medication, if you do - do not start taking it again. This can cause a FATAL allergic reaction. To avoid this a Doctor's supervision is necessary. |
|
| Zerit (d4T) | Facial wasting, nausea, peripheral neuropathy: more rarely: pancreatitis |
Nucleotide Reverse Transcriptase Inhibitors - Nucleotide
analogues are very similar to nucleoside
analogues (or 'nukes') preventing HIV from entering the nucleus of healthy
T-cells and preventing the cells from producing new virus and decreases the
amount of virus in the body. The only difference is that nucleotide analogues,
unlike nucleoside analogues, are chemically preactivated and thus require less
biochemical processing in the body for them to become active.
| Viread (tenofovir disoproxil fumarate) | nausea, vomiting, diarrhea, flatulence (intestinal gas), and loss of appetite. | Long term effects are not yet known, but may be similar to "nuke" side-effects. |
(NNRTIs or 'Nerts') Non-Nucleoside Reverse Transcriptase Inhibitors - Like the nucleoside analogs, they interfere with the reverse transcriptase enzyme essential for viral replication. they have a different mechanism of action and a distinct side effects profile.
| Rescriptor (delavirdine) | Elevated liver enzymes, fatigue, headache, rash, stomach upset. | Resistance develops very easily in the NNRTI class - meaning that if you are taking one of these, adherence to medication is a must or it will become useless. |
| Sustiva (efavirenz) | Anxiety, confusion, depression, dizziness, drowsiness, elevated liver enzymes, fever, inability to concentrate, insomnia, nausea, nightmares, paranoia, rash, stomach upset, more rarely: suicidal tendencies. | |
| Viramune (nevirapine) | Elevated liver enzymes, headache, rash, stomach upset: more rarely: liver inflammation. |
ISSUES AROUND HIV/AIDS
Why do people think it won't happen to them?
This is a good question that I can't
really answer.
The best I can do is ask you to think about why you think it can't or won't
happen to you, then read all of this site, and do your research to knock all
those reasons down.
Know how to protect yourself, and follow through on it (every time, because it
only takes once) ... or it can happen to you.
Do you have a medical explanation or recommend any link about this
matter?
Please forgive me if this question is so stupid!
Your question is not stupid.
Homosexuals are NOT at a higher risk then heterosexuals.
The virus does not discriminate against people. It doesn't care WHO you are, it
cares WHAT YOU DO for it's survival.
As you
may or may not know America is the only part of the world with a
disproportionate number of Homosexual infections. Throughout the rest of the
world it is near equally spread across the population (and we in the US are
quickly catching up to them in the statistical spread).
Just for those that may not know - you are in a risk group if you have had sex,
used intravenous drugs, or come in contact with infected fluids (like blood,
semen, vaginal fluid or breast milk). This is all the virus cares about, not
your age, race, religion, sex or sexual preference. Thus it is the way people
interact within a culture that fills in the rest of the transmission patterns,
thus Transmission and sociology (or culture) could be contributing causes.
The CDC (Center for Disease Control) identified the original carrier (to the
US) as a Homosexual that traveled extensively. The fact that he was a Homosexual
was just chance. This lead to the idea that it was a 'gay virus'. We quickly
became educated otherwise, but the stigma remained. However, because the 'zero
patient' was gay, the virus spread first in the
Homosexual population. Fifteen to 20 years ago our country held marriage and
monogamous relationships in the forefront and considered Homosexuality a
forbidden thought. With this set up, (relatively speaking) only Homosexuals
where having frequent sexual contact with multiple partners that would not come
forward and admit it. This made it difficult to track. Also, because it infected
a group of people in the minority and that was frowned upon - government
agencies looked the other way thinking it would only effect Homosexuals.
In our country it took A LOT of hard work to remove AIDS from the idea that it
was "God's retribution" against undesirables like Homosexuals and drug
users.
This ignorance is now haunting us as we now catch up to the rest of the world in
infection rates among women and children. I still find it funny that now
infection rates in Homosexuals is down drastically because they became the most
educated against the spread.
None of this has been proven or documented to my knowledge. The CDC does have a Web Page that may have information on infection rates and the reason for them, but every time I have tried to find anything on their pages I get lost in the Scientific jargon and political overtones.
If you want a more medical reason, there are two to consider. The rectum tends to be subject to tiny tears during intercourse. Thus blood, semen and other fluids are combine providing a rich environment for the virus. (Note, this would seem that you would only be at risk if you where the 'bottom' or the one receiving intercourse in the rectum. THIS IS NOT TRUE.) Second, there are different strains of the virus. Our version of the virus doesn't seem to be present in vaginal fluids as much as the versions in Europe and Africa. This is probably due to the virus mutating in different environments in the different cultures.
The best link I can suggest would be AEGIS.COM because it has a comprehensive library and HIV/AIDS search engine.
I hope I have answered your question, and I thank you for it.
Keep asking, and learning.
Yes and No, depends on what you call progress.
Many that say we are making progress are the ones that want you to
believe the epidemic is over because AIDS deaths are down. AIDS deaths
are down, because of the advances in medicine and health care (if you can get
it).
However, that means that care programs and resources are being taxed and
strained because there are more people living with AIDS/HIV. There is
still no cure, and the epidemic is just getting started because the rates of new
infections is still quite startling.
We are not making nearly enough progress for the care of those living with
HIV/AIDS, or in halting the spread of the virus.
This is the proverbial "One step forward, two steps back."
Does a pregnant woman with AIDS / HIV always pass it on to their unborn child? What are the odds?
No, she does not always pass it on to the unborn child. The odds are
getting better (last I heard the odds where - with out
medication you pass it to the child with a 1 in 4 chance - with medications it
drops to a 1 in 12 chance).
If you are pregnant and HIV+ make sure your Dr. is aware of it. What generally
happens is that the mother will start (if she hasn't already) a cocktail of
drugs in the last trimester to get the viral load as low as possible. The virus
isn't passed on through the umbilical cord - it is passed on during the birth
process. Thus by getting rid of as much of the virus as possible - the child has
a better chance of not contracting the virus during birth.
The next risk factor for the child is then in post-natal care. You can't breast
feed for example. The Dr. will advise you on all the precautions to be taken.
By the way - this is a very new process. There may be some long range problems
for the child from the medications that we have yet to see.
How should you go about telling someone you have HIV? (Disclosure)
This is a big and very personal debate for each person having to face it - not only for HIV/AIDS but for anything that is contagious.
There is no right or wrong way. There is no easy way. Every situation and
person will be different.
DO WHAT MAKES YOU COMFORTABLE.
Suggestions:
Know how the virus is transmit and be responsible enough to teach anyone that
you tell. Let them decide what risks they are willing to take.
Consider when YOU would have liked to of known from a partner they were HIV
positive. Tell the other person then.
If asked, then tell them - they obviously want to know.
Be honest.
If you are told by someone that they are HIV+ and you are upset about the
timing on it - ask yourself ... Are you upset
because they didn't tell you - or because you forgot to ask?
Don't put the burden on someone else. It is as much your responsibility to ask,
as it is for them to tell.
How does it affect you Family and Friends?
Everyone will be effected differently. Everyone is a
unique individual with different information and experiences at there disposal
to affect the way they react to someone with HIV/AIDS.
It will however effect them some how. They can't be an important part of someone's
life, and not be affected by the information that someone they know and love is
now infected with this virus.
I would hope they respond with Love, Support and Understanding - but many times
it is also Anger, Fear and Ignorance.
What research is going on right now?
Most of the research in HIV and AIDS is still centered around treatment or
medications.
There is work being done on a Vaccine that will prevent further infections.
Not much has been discovered in the way of a 'cure'.
For the most up-to-date information on HIV/AIDS research I recommend AEGIS.COM which posts the most recent articles and has a search engine for their site.
