Guillain-Barré Syndrome

GBS is an acute immune-mediated peripheral neuropathy with heterogeneous demyelinating and axonal forms. The classic syndrome includes progressive motor difficulty, absent deep-tendon reflexes, paresthesias without objective sensory loss, and CSF albuminocytologic dissociation. BMJBMJGuillain-Barre syndrome - Symptoms, diagnosis and treatment | BMJ Best Practice US An antecedent respiratory or gastrointestinal illness occurs in approximately two thirds of patients and may precede neurologic symptoms by up to 6 weeks.

Assess trajectory, bulbar function, facial weakness, cough effectiveness, respiratory symptoms, autonomic symptoms, pain, and ability to walk independently at presentation and serially. Severe generalized GBS with respiratory failure affects approximately 20% to 30% of cases; one source estimates that one quarter of patients require assisted ventilation.

GBS remains clinically defined. CSF albuminocytologic dissociation—elevated protein with a normal cell count—is a classic supportive finding.

Order nerve-conduction studies and electromyography to support GBS and characterize demyelinating versus axonal physiology. Early studies may be incomplete or nonspecific: absent H reflexes were reported as the most sensitive early electrodiagnostic finding, while upper-extremity sensory nerve action potentials, F waves, and other parameters may also be abnormal.

IVIG and plasma exchange are the two proven immunotherapies for GBS and are described as equally effective.

Supportive care is central because respiratory failure, cranial neuropathy with dysphagia, autonomic dysfunction, pain, and prolonged disability drive acute morbidity.

At follow-up, document walking ability, cranial and respiratory recovery, pain, fatigue, sensory symptoms, autonomic symptoms, and return to activities. Persistent progression or recurrent deterioration should trigger diagnostic reassessment, including acute-onset CIDP, rather than automatic escalation of GBS treatment.

Most GBS cases are not associated with vaccines. CDCCDCGuillain-Barré Syndrome and Flu Vaccine | Influenza (Flu) | CDC CDC reports that evidence regarding seasonal influenza vaccine and GBS varies across seasons; if increased risk exists, it is small—about 1 to 2 additional cases per million vaccine doses administered.
