Guillain-Barré syndrome (GBS) is an acute, frequently severe, and fulminant polyradiculoneuropathy that is autoimmune in nature in which your body’s immune system attacks your nerves.
- GBS appears days or weeks after a respiratory or digestive tract infection.
- COVID-19 virus
- Swine influenza vaccine
- Recent surgery
- Influenza vaccinations
- Childhood vaccinations
- Rabies vaccine
- Most commonly, infection with campylobacter, a type of bacteria often found in undercooked poultry
- Influenza virus
- Epstein-Barr virus
- Zika virus
- Hepatitis A, B, C and E
- HIV, the virus that causes AIDS
- Mycoplasma pneumonia
- Hodgkin’s lymphoma
- COVID-19 Johnson & Johnson vaccine
- Prickling, pins and needles sensations in your fingers, toes, ankles or wrists
- Weakness in your legs that spreads to your upper body
- Unsteady walking or inability to walk or climb stairs
- Difficulty with facial movements, including speaking, chewing or swallowing
- Double vision or inability to move eyes
- Severe pain that may feel achy, shooting or cramplike and may be worse at night
- GBS manifests as a rapidly evolving areflexic motor paralysis with or without sensory disturbance.
- The usual pattern is an ascending paralysis that may be first noticed as rubbery legs.
- Weakness typically evolves over hours to a few days and is frequently accompanied by tingling dysesthesias in the extremities.
- The legs are usually more affected than the arms, and facial diparesis is present in 50% of affected individuals.
- The lower cranial nerves are also frequently involved, causing bulbar weakness with difficulty handling secretions and maintaining an airway.
- Pain in the neck, shoulder, back, or diffusely over the spine is also common.
- Deep tendon reflexes attenuate or disappear within the first few days of onset.
- Cutaneous sensory deficits (e.g., loss of pain and temperature sensation) are usually relatively mild.
- Wide fluctuations in blood pressure, postural hypotension, and cardiac dysrhythmias.
- Acute inflammatory demyelinating polyneuropathy (AIDP)
- Acute motor axonal neuropathy (AMAN)
- Miller Fisher syndrome (MFS)
- Acute pharyngeal cervicobrachial neuropathy (APCBN)
GBS results from immune responses to nonself antigens (infectious agents, vaccines) that misdirect to host nerve tissue through a resemblance-of-epitope (molecular mimicry) mechanism. The neural targets are likely to be gangliosides. Gangliosides are present in large quantity in human nervous tissues, such as nodes of Ranvier.
