Man : Reckless Life (HIV/AIDS)
HIV/AIDS
Human
immunodeficiency virus (HIV) is a lentivirus
(a member of the retrovirus family) that causes acquired immunodeficiency
syndrome (AIDS), a condition in humans in which progressive failure of
the immune
system allows life-threatening opportunistic infections and cancers to thrive.
i.
HIV infects vital cells in the human immune
system such as helper T cells (specifically CD4+ T cells),
macrophages,
and dendritic
cells.
ii.
HIV infection leads to low levels of CD4+
T cells
through three main mechanisms:
a.
First, direct viral killing of infected
cells;
b.
second, increased rates of apoptosis in
infected cells; and
c.
killing of infected CD4+ T cells
by CD8 cytotoxic lymphocytes that recognize
infected cells.
When
CD4+ T cell numbers decline below a critical level, cell-mediated immunity is lost, and the body
becomes progressively more susceptible to opportunistic
What's the big deal about HIV and AIDS?
What’s the big fuss about AIDS
and HIV for other people to
worry about - the gay people, drug users, people who sleep around the one that
need the focusing. However it is a wrong for conclusion - all teens, all humanity;
need to take the threat of HIV, the virus that causes AIDS, seriously. To be
able to protect yourself, you need to know the facts, and know how to avoid
becoming infected.
Isn't
it only a problem for adults?
HIV
is a big problem for young people, as well as adults. It is estimated that
there were
a. 3.4
million children (under 15 year olds)
b. 5
million young people (15-24 year olds) living with HIV in 2010
c. one
third of all new HIV infections are among people aged 15-24.
Globally AIDS is the second
most common cause of death among 20-24 year olds.
What's
the difference between HIV and AIDS?
HIV is the virus that causes AIDS. HIV stands for the 'Human
Immunodeficiency Virus'.
AIDS stands for the 'Acquired
Immune Deficiency Syndrome'.
AIDS is a serious condition
that breaks down the body's defense system against illness. This means that
people with AIDS can get many different kinds of diseases which a healthy
person's body would normally fight off quite easily.
How
long does it take for HIV to cause AIDS?
Now, there are many drugs
(called antiretroviral drugs) that can be used to help people with HIV. People
living with HIV can be treated for a very long time with antiretroviral
drugs that prevent or delay the onset of AIDS. If someone infected
with HIV does not take treatment, then it usually takes around ten years for
AIDS to develop - however this varies from person to person. Many people around
the world do not have access to antiretroviral treatment and therefore people
continue to die from AIDS.
So how
do you get infected with HIV?
HIV is passed on in the sexual
fluids or blood of an infected person, so if infected blood or sexual fluid
gets into your body, you can become infected. This usually happens by either
having sexual intercourse with an
infected person or by sharing needles used to inject drugs with an infected
person. People can also be born with HIV if their mother is infected and a very small
number of people become infected by having medical treatment using infected
blood transfusions.
Three stages of HIV infection.
- The initial stage of infection (primary infection), which occurs within weeks of acquiring the virus, and often is characterized by a flu- or mono-like illness that generally resolves within weeks.
- The stage of chronic asymptomatic infection (meaning a long duration of infection without symptoms) lasts an average of eight to 10 years.
- The stage of symptomatic infection, in which the body's immune (or defense) system has been suppressed and complications have developed, is called the acquired immunodeficiency syndrome (AIDS). The symptoms are caused by the complications of AIDS, which include one or more unusual infections or cancers, severe loss of weight, and intellectual deterioration (called dementia).
HIV can't be caught by kissing, hugging or shaking
hands with an infected person, and it can't be transmitted by sneezes, door
handles or dirty glasses. The most common ways in which HIV is spreading
throughout the world include sexual
contact, sharing needles, and by transmission from infected mothers to their
newborns during pregnancy,
labor (the delivery process), or breastfeeding.
What is
'safe sex'?
Sex means sexual intercourse or
'penetrative sex' and cannot be described as 'safe sex'. Safe sex means sexual
activities even if one person is infected with HIV, and definitely won't pass
it on to the other person. Sexual activities such as kissing, cuddling,
massaging and rubbing each other's bodies. But if you have any cuts or sores on
your skin, make sure they are covered with plasters (band-aids). Nothing you do
on your own can cause you to get HIV - you can't get infected by masturbating.
What
about using drugs?
The only way to be safe around
drugs is not to take them. If you are on drugs you are taking risks you
normally wouldn't take, as an unsafe sex when you would normally be more
careful. If you take drugs, you might find it more difficult to use a condom or
you might forget altogether. One of the most common drugs this can happen with
is alcohol - if you're drunk, you might not always know what you're doing, or
you might not care.
If you inject drugs, always use
a clean needle, syringe and spoon, water, etc each time you inject, and never
share any of these with anyone else. If you snort drugs, and you use a note or
a straw to snort through, shouldn't share it, as blood can be passed from the
inside of one person's nose to another.
If you have a tattoo or a
piercing, you should make sure that the needles and equipment used are sterile.
What is
safer sex?
Safer sex also means using a
condom during sexual intercourse. Using a condom is not absolutely safe as
condoms can break, but condoms can be effective if they are used correctly.
Oral sex (one person kissing,
licking or sucking the sexual areas of another person) does carry some risk of
infection. If a person sucks the penis of an infected man, for example,
infected fluid could get into the mouth. The virus could then get into the
blood if you have bleeding gums or tiny sores somewhere in the mouth. The same
is true if infected sexual fluids from a woman get into the mouth of her
partner. But infection from oral sex
alone seems to be very rare.
Can you
get infected your first time?
You can become infected, if your partner has HIV and
you have unsafe sex. Sexual transmission of HIV has been described from men to
men, men to women, women to men, and women to women through vaginal, anal, and
oral sex. The best way to avoid sexual transmission is abstinence
from sex until it is certain that both partners in a monogamous relationship
are not HIV infected.
Is
there a cure?
There is no cure for HIV
or AIDS. HIV is a virus, and no cure has been found for any type of virus.
Recently, doctors have been able to control the virus once a person is
infected, which means that a person with HIV can stay healthy for longer, but
they have not managed to get rid of the virus in the body completely.
How can
I tell if someone's infected with HIV?
There is no way to tell just by
looking at someone whether they are infected with HIV. Someone can be infected
but have no symptoms and still look perfectly healthy. They might also feel
perfectly healthy and not know themselves that they are infected. The only way
to know if a person is infected or not is if they have an HIV test.
In 1985, a blood
test became available that measures antibodies to HIV that are the body's
immune response to the HIV. The test used most commonly for diagnosing
infection with HIV is referred to as an ELISA. If the ELISA finds HIV
antibodies, the results must be confirmed, typically by a test called a Western
blot. HIV antibody tests remain the best method for diagnosing HIV infection.
Recently, tests have become available to look for these
same antibodies in saliva, some providing results within one to 20 minutes of
testing. Antibodies to HIV typically develop within several weeks of infection.
During this interval, patients have virus in their body but will test negative
by the standard antibody test, the so called "window period." In this
setting, the diagnosis can be made if a test is used that actually detects the
presence of virus in the blood rather than the antibodies, such as tests for
HIV RNA or p24 antigen.
A new test has been approved that measures both HIV
antibodies and p24 antigen, shrinking the duration of the window period from
infection to diagnosis. There also are many testing centers around the country
that are routinely screening blood samples that are HIV-antibody negative for
HIV RNA.
How can
I get tested?
It's much better to talk to
someone than to worry on your own. The clinic will suggest that you wait three
months after your last risky sexual contact before having a test. This is
because the virus is difficult to detect immediately after infection.
Will
they tell my parents?
Clinics in different places have different
policies. Most (but not all) clinics have a confidentiality policy, and will
not tell anyone, although some places will want to bring a parent to give
consent. You can phone the clinic before you go to find out.
What
will they do?
Before they do anything, the
doctor or nurse will ask if you're sure you want to have a test. They will
usually take a sample of blood from you to examine. If you also want to be
tested for STD's,
they may take a urine sample, or they might ask if they can take a swab from
the vagina or penis. Some places can give you the results on the same day, in
other places you may have to wait for a week or more. While you wait, you
shouldn't have sexual contact with anyone.
I have
HIV - what should I do?
If you have found that you have
HIV, you will need to consider telling the people who you have had sex with and
anyone you have shared needles with so that they can decide if they want to
have a test. This can be a very difficult thing to tell someone. If you think
you can't tell them, your doctor or nurse may be able to help you. Your doctor
at the clinic should also be able to give you more advice about how to stay
healthy. They will also be able to tell you if you need to have any other blood
tests done, and talk to you about medication.

What are symptoms and signs of
HIV infection and AIDS in men, women, and children?
The time from HIV infection to
the development of AIDS varies. Rarely, individuals develop complications of
HIV that define AIDS within one year, while others remain completely
asymptomatic after as many as 20 years from the time of infection.
However, without antiretroviral
therapy, the time from initial infection to AIDS is approximately eight to 10
years. The reason why people experience clinical progress of HIV at different
rates.
Within weeks of infection, many
people will develop the symptoms of primary or acute infection which typically
has been described as a "mononucleosis" or "influenza" like
illness but can range from minimal fever,
aches, and pains to very severe symptoms. The most common symptoms of primary
HIV infection are
- fever,
- aching muscles and joints,
- sore throat,
- and swollen glands (lymph nodes) in the neck.
During the first weeks of
infection when a patient may have symptoms of primary HIV infection, antibody
testing may still be negative (the so-called window period).
After primary infection, most
individuals enter a period of many years where they have no symptoms at all.
During this time, CD4 cells may gradually decline, and with this decline in the
immune system, patients may develop the mild symptoms of HIV such as vaginal or
oral, fungal
infections of the nails, a white brush-like border on the sides of
tongue called hairy leukoplakia,
chronic rashes,
diarrhea,
fatigue,
and weight loss.
With a further decline in
function of the immune system, patients risk of developing more severe
complications of HIV, including many more serious infections (opportunistic
infections), malignancies, severe weight loss, and decline in mental function.
Most physicians think about
patients with HIV diseases as having no symptoms, mild symptoms, or being
severely symptomatic.
Psychological Effects of HIV/AIDS
Getting diagnosed with HIV elicits
many different emotions and psychological effects.
Depression
Characterized by feelings of
guilt, difficulty sleeping, feelings of hopelessness and helplessness. Some
people have a preoccupation with death or thoughts of suicide. Having HIV or
AIDS can lead to depression in some people. The need to counseling to discuss their
feelings. In some cases, therapy and medication are required.
Anxiety
Excessive fear and apprehension
or panic and accompanied by physical complaints such as chest pain, shortness
of breath, headaches or other problems. People with HIV or AIDs who experience
anxiety symptoms may benefit from learning relaxation exercises such as
progressive relaxation, meditation or yoga. In some cases, you may need therapy
or medication.
Cognitive
Problems
People with HIV sometimes experience cognitive
problems related to the disease, may experience dementia complex, delirium and
psychosis. Symptoms such as forgetfulness, inability to make decisions,
attention problems, speech difficulties, confusion or other problems.
Other
Emotions
Experiencing feeling of guilt,
fear, sadness, embarrassment or confusion. Support from loved ones or community
groups, medical providers, counselors, psychologists and psychiatrists. Become
educated about the disease and treatments available to empower you to lead a
healthier life, physically and emotionally.
Treatments
for HIV
Though there is no cure for HIV there are a number of medications which can improve the sufferer’s quality of life and delay the onset of AIDS for longer periods of time. Different types of medications block the virus in various ways. HIV research shows best results when combination therapy is used by combining at least three different drugs from two different categories. This prevents the HIV virus from mutating and becoming immune to the medications being used. The categories of HIV drugs are:
Though there is no cure for HIV there are a number of medications which can improve the sufferer’s quality of life and delay the onset of AIDS for longer periods of time. Different types of medications block the virus in various ways. HIV research shows best results when combination therapy is used by combining at least three different drugs from two different categories. This prevents the HIV virus from mutating and becoming immune to the medications being used. The categories of HIV drugs are:
A. Drugs
:
i.
NNRTI’s:
Non-nucleoside reverse transcriptase inhibitors work by disabling a specific
protein which HIV needs to reproduce. Examples are efavirenz, etravirine and
nevirpaine.
ii.
NRTI’s:
Nucleoside reverse transcriptase inhibitors are ‘fake’ building blocks that HIV
needs to reproduce. These fake blocks contain faults which essentially slow the
virus from copying itself. Examples are abacavir and combination drugs
emtricitabine and tenofovir.
iii.
PI’s: Protese
inhibitors disable a protein that HIV needs to reproduce. Examples include
atazanavir and darunavir.
iv.
Entry or fusion
inhibitors: This category of drugs prevents HIV from
entering the CD4 cells. Examples are enfuvirtide and maraviroc.
v.
Integarse Inibitors:
This category again disables a protein, one which HIV specifically uses to
insert itself into the CD4 cells.
B.
Beyond Medication: A Healthy Lifestyle
Besides taking medications, there are many different
lifestyle changes which can be made to improve the quality of life of someone
who’s been infected with HIV.
a.
Eating a more nutritious
diet:
Improving
dietary intake can help slow down the progression to AIDS, improve their weight
and prevent weight loss (which usually occurs with the virus) as well as
improve their overall feeling of well-being, even with the symptoms that HIV
can bring on.
A
healthy diet for someone with HIV includes whole grains, low fat dairy
products, protein and lots of fresh fruits and vegetables. Multivitamins are
also a good idea to take, but remember to consult the doctor first. Fried food
and sugary drinks, such as processed juices and sodas, should be eliminated.
b.
Exercising:
Regular,
moderate exercises helps improve muscle mass, improves breathing, reduces
stress, increases bone strength, improves appetite, improves sleep, and helps
control glucose levels. People with HIV are especially prone to dehydration,
losing body mass and infections from injuries so it’s important to talk to the
doctor about the type and frequency of exercise.
c.
Quitting
·
Smoking
·
Stopping illicit drug use
·
Practicing safer sex
·
Getting tested and treated for STI’s
·
Taking steps to prevent infection
C. Support
Groups for HIV
For someone who is living with HIV,
having a support group to discuss day to day difficulties or even to provide
support to someone else with HIV is a good way to improve mental and emotional
health. Below are some links that will provide information on both online and
offline support systems for people with HIV or AIDS.
"The
global HIV/AIDS epidemic is an unprecedented crisis that requires an
unprecedented response. In particular it requires solidarity -- between the
healthy and the sick, between rich and poor, and above all, between richer and
poorer nations. We have 30 million orphans already. How many more do we have to
get, to wake up?"
Kofi Annan
