Guillain-Barre syndrome Flashcards
what is Gullian barre syndrome
- autoimmune & inflammation damage to peripheral nervous system
- aute, generalized paralysis
what always comes with autoimmunity
autoimmunity causes inflm, so with autoimmunity comes inflm
how does classic autoimminty come about
-for classic autoimmunity always preceded by an infection that triggers autoimmunity, so immune response is producing antibodies and T cells, then something changes in immunity causing target of self component
gullian barre syndrome essentially presents as
acute generalized paralysis
Etiology of Guillian Barre syndrome
- idiopathic
- preceded by infection (1-4 wks)
guillian barre syndrome preceded by
infect (1-4 wks before)
most common: campylobacter jejuni (bacterium, tend to encounter in unpasteurized milk, poultry, contaminated water)
also can be causes by viruses such as EBV
Patho of Guilian-Barre syndrome
antibodies and t cells target myelin sheath (in peripheral nervous system)
schwann cell damage
what cells make up the myelin sheath in the peripheral nervous system
schwann cells
mnfts of Guillian-Barre syndrome
- progressive ascending muscle weakness & paralysis
- partheisias (numbness & tingling sensation in periphery)
- partheisia (ascending usually origin in periphery hands & feet)
- deep muscle pain (shoulder & thigh)
- complete paralysis (may or may not happen based on intervention)
- respiratory failure (aprox 25%) approximately 25% will progress till respiratory failure
Diagnosing Guillian-Barre syndrome
- history (history to exclude things such as myasthenia gravis)
- physical exam (weakness & reflexes)
- nerve conduction (stimulate nerve electrically & see if conducting, if demylinated conduction will be impaired)
- CSF (for exclusion, some changes elevated protien content because inflm in PNS if close to spinal cord)
Treatment of Guillan-Barre syndrome
- life support (respiratory system)
- plasmapheresis (take blood seperate palasma from cells, plasma has antiboides and other neurotoxic compounds discard plasma, to get rid of antiboides from circulation)
- IV igG (give antibodies because low from plasmapheresis)
- 80-90% recover in 6-12 months(
with Guillan-Barre syndrome disease mnfts _________ and recover in ________
mnfts in ascending (periphery damage first & vital organs-breathing muscles last)
and recover in descending (vital organs, breathing recover first then periphery)
Guillian-barre syndrome you have to ________ not _______
you have to intervene not self-limiting
