SYNDROME
OF ACQUIRED IMMUNODEFICIENCY: an
infection
by virus that causes
a
complete
failure
of the immunological
system
of the body.
Due to this virus, the immunological
system
(that includes the lymphocytes of the blood, the
spinal
marrow, the
liver
and the lymphatic glands) cannot produce antibodies that protect the organism against the
infections
and the
cancer
.
The virus that causes it is the Virus of Human Immunodeficiency or VIH (also HIV; of
English
) of that there are two main types, 1 and 2, and multitude of variants.
At the present time one calculates that 30 - 40 million people are infected anywhere in the world.
It is the cause commonest of death in the western world in men of 25 to 44 years.
Causes.
Infection
of virus VIH
transmitted
by:
Sexual
relations without protection.
Use of needles or contaminated injections.
Contact
with blood or derivatives contaminated.
Transmission
mother
- son.
The
AIDS
is not
transmitted
by accidental
contact
(to occur the hand,
a
kiss, etc. It is necessary an intimate
contact
or
a
contact
with contaminated fluids (serum, blood, etc.
The carrying person of virus VIH IS NOT
a
RISK FOR the GENERAL POPULATION.
Signs and symptoms.
The initial
infection
can not produce symptoms, or
a
picture like the
influenza
, that lasts one week and usually it is not related to the
disease
. Later it passes
a
period
of months in which some is no symptom, and the tests to detect the
infection
are negative, since months in becoming take positive, not being able to assure his result until about six months after the suspicious
contact
.
In the following phase, of
primary
infection
, already the analytical tests have been positivado, detecting the antibodies in the blood.
The third phase is
a
more or less inactive and prolonged phase. The patient is well,
but
already she
has
the
infection
, that is advancing inexorably. In this stage, the medication is effective to reduce the viral load and to delay the appearance of the
AIDS
.
Phases fourth and villa:
they are the beginning of the
AIDS
. The immunological defenses already are too much debilitated to protect the organism. The virus also
attacks
the
nervous
cells and appear:
Recurrent
fatigue, loss of
weight
,
infections
(
respiratory
, of the digestive apparatus, the skin, etc. that respond bad or they do not respond to the conventional treatments.
Inflamed fever, lymphatic ganglia, buccal increase as large as bazo, diarrea, ulcers and opportunistic
infections
by agents (virus,
bacteria
or fungi) who usually do not cause
diseases
in the healthy people.
Factors of risk.
Manifold even masculine homosexuals.
Manifold even heterosexual.
Exhibition of the workers of hospital,
aids
from laboratory to blood and other fluids of VIH patients.
Pinchazos with infected needles.
Children
born of positive
mother
VIH.
Intravenous drug
addiction
.
Transfusions before 1985, when the tests settled down to discard it in the blood donation points.
Prevention.
To avoid
sexual
contact
with affected people, or known drug users intravenous.
The
sexual
activity
will have to be restricted to pairs of the well - known
sexual
history.
To use you reduce for the
vaginal
and anal penetration.
To avoid the
sexual
relations when they are had wounded or
infections
in the parts pudendas (penis,
vagina
and
vaginal
introito)
To avoid intravenous drug self administration.
Not to share syringes. Not to use syringes without sterilizing.
To avoid transfusions of nonregistered blood.
Diagnosis and treatment.
The analytical tests can not give positive up to 6 months after the
contact
.
The precocious diagnosis is very recommendable.
General Measures.
To avoid to expose
itself
to
infections
.
To avoid conducts of risk for the others.
Psicoterápico treatment or medical advice to avoid the produced
depression
to suffer the
disease
.
To
contact
immediately the groups of aid of the
AIDS
.
To treat any
infection
or complication.
To hospitalize if there are serious complications.
Medication.
Until the moment the
infection
does not have cures,
but
there is control of the same and medication that it avoids that the
disease
progresses.
The present treatments, that combine three or more antiviral medicines, like zidovudina, inhibitors of the protease and inhibitors nucleósidos of transcriptasa inverse are not able to delay or to slow down the advance of the
disease
.
Activity
.
Exercise must be made daily.
Diet.
To maintain an feeding
optimal
.
To avoid nonpasteurizada milk or potentially contaminated foods.
Complications.
Serious
infections
in
organic
systems by opportunistic germs: Neumocistitis, Toxoplasmosis, Citomegalovirus, Candida albicans, Tuberculoses, etc. are most
common
.
The
cancer
of skin (Sarcoma de Karposi) and linfomas (
cancer
of the lymphatic cells) are frequent.
Also the encefalopatía and the
meningitis
by the VIH.
Prognosis.
It is
a
incurable
disease
. Nevertheless the symptoms can be reduced and the
disease
can that is not developed with the suitable medication, in 5 to 15 years, after giving to positive virus VIH.
There is
a
population group (the slow progresores) that by
a
congenital
deficiency
is resistant to the
infection
, not developing it or evolving very slowly.
Once it appears the
AIDS
, the average time of survival is of two years and average; although the new treatments improve year after year this statistic.
