Study Notes
Diagnostic Criteria for GBS
- Characterized by progressive and relatively symmetrical weakness.
- Presence of decreased or absent myotatic reflexes is an essential diagnostic feature.
Common Subtype of GBS
- Acute inflammatory demyelinating polyradiculoneuropathy (AIDP) is the most prevalent subtype of Guillain-Barré syndrome (GBS).
Pre-Onset Symptoms
- Typical complaints prior to GBS onset include respiratory or gastrointestinal symptoms.
Infectious Pathology Linked to GBS
- Campylobacter jejuni infection is the most common infectious agent associated with the development of GBS.
Pathophysiology of GBS
- GBS is fundamentally an inflammatory neuropathy caused by cross-reactivity between neural antigens and antibodies, triggered by specific infections.
Mechanism of C. jejuni in GBS
- C. jejuni contains lipooligosaccharides on its bacterial wall, which are structurally similar to gangliosides.
- This similarity leads to molecular mimicry, resulting in the formation of antiganglioside antibodies that attack peripheral nerves.
Common Symptoms Before GBS Onset
- Fever, cough, sore throat, and upper respiratory tract infections (URTI) are the most frequently reported symptoms prior to GBS diagnosis.
Association with Other Infections
- Epstein-Barr Virus infection has been linked to milder forms of GBS.
First-Line Treatment for GBS
- Plasma exchange is the primary treatment recommended for managing GBS.
Use of Corticosteroids
- Corticosteroids are not recommended for the treatment of Guillain-Barré syndrome.
