Guillain-Barré syndrome is a rare disorder that
causes injury to peripheral nerves. These nerves send messages from the brain
to muscles, instructing the muscles to move, but also carry sensations such as
pain from the body to the brain. Nerve injury causes muscle weakness, often to
the point of paralysis and can cause problems with sensation, including pain,
tingling, "goosebumps" or a certain amount of numbness (numbness).
Guillain-Barre syndrome can become a medical emergency weakness to affect the
chest muscles responsible for breathing, as when they are paralyzed, patients
may die due to lack of oxygen. Individuals with this syndrome should be
monitored frequently, usually in a hospital, to ensure that breathing and other
vital functions remain effective.
Guillain-Barre syndrome is an autoimmune disorder in which the body's immune
system attacks and destroys the myelin sheath which surrounds the long bodies
of nerve cells (neurons) as if an insulation around a water pipe . Myelin
protects nerve and helps speed the transmission of electrical impulses through
the nerve. If this is destroyed, nerve impulses traveling to go very slowly and
may even be interrupted. If the muscles do not receive adequate stimulation
through the nerves, will not work properly.
Unaware of the causes of the syndrome, but many experts think that the immune
system is trying to fight an infectious microorganism (bacteria or virus) and
yet harms accidentally nerve tissues.
Guillain-Barré syndrome is rare and is estimated to affect about 100 people a
year in Portugal. The reason for the disturbance to reach some people is a
mystery. In over two thirds of patients, Guillain-Barre syndrome occurs one to
three weeks after a viral disease, including common cold, flu, or infection
with human immunodeficiency virus (HIV), Epstein-Barr or cytomegalovirus. The
trigger factor seems to be most common infectious bacterial infection by
Campylobacter jejuni, which often cause intestinal infections. Sometimes,
Guillain-Barré seems to follow the immunization, surgery or bone marrow
transplantation. The study of the causes of Gulliain-Barré syndrome is a topic
of growing clinical research.
Treatment
Most patients with Guillain-Barré is hospitalized, because the disturbance may
weaken the chest muscles to such an extent that can lead to severe breathing
difficulties. In a hospital, may monitor patients up and put them in a fan if
necessary. If Guillain-Barré cause paralysis of the muscles of the leg or arm,
the affected person may need help with activities of daily living, such as
eating and going to the bathroom. The monitoring of cardiac function and blood
pressure and other supportive care (including psychological support, pain
management, skin care, prevention of blood clots and physiotherapy) are also
important.
Two treatments shown to reduce the severity of Guillain-Barré and speed
recovery:
• Plasmapheresis (plasma exchange or) is a process in which blood is removed
from the patient and then separated into plasma (the liquid part of blood) and
blood cells. After only blood cells are replaced again in the body causing the
body to fabricate most plasma offset has been removed. Nobody knows why this
treatment works, but most scientists believe that plasmapheresis removes
substances that contribute to the immune system attack on the peripheral
nerves.
• Infusions immunoglobulin, a mixture of antibodies that are produced naturally
by the body's immune system. The high doses of immunoglobulin can result in
blocking the antibodies that may have contributed to the disturbance.
These two are considered equally effective types of treatments; the choice of
treatment determined by several factors, such as availability of treatment and
patient preference. Is chosen, often immunoglobulin infusion because of their
ease of administration. Currently under investigation are other treatments for
Guillain-Barré syndrome.
After the beginning of restoration, it is likely that patients require therapy
to help them to resume adequate force and motion.
Prevention
Given that no one knows what causes Guillain-Barré syndrome, there is no way to
avoid it.
