Guillain-Barre Syndrome

• An acquired disease of the peripheral nervous system

• Major features: weakness and areflexia• The most common cause of acute

flaccid paralysis in all ages. • No specific test to confirm the

diagnosis• A syndrome rather than a disease

Epidemiology

• Annual incidence: 0.4 – 1.7 / 100.000

• Rare before 1 year of age• M:F - 1.5:1

Guillain-barre Syndrome Clinical features

• Progressive weakness and diminished deep tendon reflexes in a symmetric distribution.

• Ascending progression – most common

• 5 – 10% upper >> lower• 5-10% proximal >> distal

Guillain-barre SyndromeClinical features

• Sensory disturbances: 40% pain or paresthesias

• Cranial nerves• Autonomic disturbances –

infrequent but life threatening. • 15-20% progress to respiratory

failure.

Guillain-barre Syndromediagnostic features

Clinical features

Stages:• Progression phase- days to weeks,

max. 6 weeks. Period of major complications

• plateau phase - days to weeks• Recovery – weeks to months

clinical variants

Laboratory findings:

CSF• normal cell count – up to 10

lymphocytes• elevated protein – 80-200 mg/dl ,

after 1 week

Laboratory findings

Electrophysiological tests:• 80% abnormal studies• Multiple nerves must be studied• Evidence of multifocal demyelination in motor

and sensory nerves. • prolonged distal latency• Reduction of the F WAVE response and H-

REFLEX. • H REFLEX – single most sensitive test for

early GBS, absent in 97% of pts in the first week )Gordon at al. neurol 2001(

Pathology

Depend upon the form of GBS. AIDP and MILLER-FISHER:• Inflammation and demyelination• More severe inflammation at the

junction of dorsal and ventral roots at the site of the dural attachment.

• Secondary axonal degeneration

Histology

Pathology

Motor and motor-sensory variants: • Axonal degeneration without an

inflammatory response• The immune process is directed at

the nodes of Ranvier• No demyelination

Pathophysiology

• Immune mediated disease• Possible mechanism: autoAB bind

to glycoproteins on peripheral myelin , causing a cascade of events which eventually destroy the myelin.

Pathophysiology

• 50 – 70% have an antecedent illness within the previous 4 weeks.

• URTI, gastroenteritis• C. Jejuni – more severe symptoms• CMV, EBV

The Lancet; Nov 5-Nov 11, 2005; 366, 9497;

• Campylobacter is the most commonly identified precipitant of GBS

• Demonstrated in up to 30% of cases• 27 / 103 pts )26%( with GBS had

evidence of C.jejuni infection compared with 1% of controls.

• 70% of those infected with C.jejuni reported diarrheal illness within 12 weeks before the onset of GBS.

Guillain-barre Syndromeand Campylobacter

• Campylobacter associated GBS have a worse prognosis – slower recovery and greater residual neurological disability.

• The risk of developing GBS during the 2 months after C.jejuni infection is 100-fold higher than the risk in the general population!

• Specific strains )class A, serotype HS:19( were found more frequently )78% vs 17%( in patients with GBS than in patients with enteritis.

• Class A strain carries gangliosid -like lipo-oligosaccharide

• Increased risk of producing antiganglioside autoantibodies and developing GBS.

Pathophysiology

Immunizations:

• “swine flu” vaccine (1976)

• Rabies vaccine

Guillain-Barré cases among recipients of meningococcal conjugate vaccine

The Food and Drug Administration (FDA) and the Centers for Disease Control and Prevention (CDC) are investigating six cases of Guillain-Barré syndrome that occurred after receipt of meningococcal conjugate vaccine (MCV4, Menactra – sanofi pasteur). This number of cases of Guillain-Barré syndrome is not greater than would be expected in an unvaccinated teenage population. However, the onset of neurologic symptoms within two to five weeks following vaccination is a reason to gather further information.

The AAP Committee on Infectious Diseases continues to recommend MCV4 for adolescents "Anyone who has ever had Guillain-Barré syndrome should talk with their doctor before getting MCV4."

Proximal weakness

Therapy

• Supportive• Monitoring: BP, HR, RR, TEMP. • Frequent physical examinations to

establish a trend. • Serial lung function testing• If dysphagia or shoulder

weakness: respiratory assistance may be necessary.

Therapy

Indications for transfer to ICU: • Respiratory failure• Autonomic dysfunction• Bulbar dysfunction• Bilateral facial weakness• aspiration

Therapy

• Anticipate the need for mechanical ventilation – better to intubate electively!

• Vital capacity < ½ normal for age or <15-20 ml /kg

• Serial measurements of pulmonary function tests were most helpful in detecting the risk of respiratory failure )Arch Neurol 2001(

• Children < 6 years – monitor fatigue: blood gases, chest x-ray.

Therapy

American Academy of Neurology recommendations for treatment of GBS: indications for treatment:

• Rapidly progressing weakness• Worsening respiratory status or need

for mechanical ventilation• Significant bulbar weakness• Inability to walk unaided.

GBS Motor Disability Scale

grade Motor disability

0 Normal

1 Minor symptoms

2 Able to walk 5 meters unaided

3 Able to walk 5 meters aided

4 Bedridden

5 Respiratory failure

6 death

Therapy

Corticosteroids:• First immunotherapy for GBS • “Corticosteroid medications do not seem to

help improve symptoms or lessen nerve damage from Guillain-Barre syndrome” - The Cochrane Database of Systematic Reviews 2000 (6 RCT’s, 195 pts treated with steroids vs 187 pts with supportive care)

• No indication as monotherapy, evidence of benefit if added to IVIG.

Plasma exchange for Guillain-Barre syndromeRaphal JC, Chevret S, Hughes RAC, Annane

"Plasma exchange is the first and only treatment that has been proven to be superior to supportive treatment alone in Guillain-Barre syndrome. Consequently, plasma exchange should be regarded as the treatment against which new treatments, such as intravenous immunoglobulin, should be judged."

Therapy

Plasma exchange• reduce length of stay in the ICU and in hospital• Reduce need for and period of ventilation• Reduce length to unaided walking and neurological sequele. • 4 double-volume exchanges on alternate days over 1 week.• exchange with albumin 5%• more beneficial when started within seven days of the

disease onset.

Therapy

• Small children: access problems )need central line – thrombosis, bleeding, infections(, CVS instability after exchange

• No EBM regarding plasmapheresis in children

Therapy

Use of plasma exchange:• severe disease• Failure of IVIG treatment• Previous adverse reaction to IVIG

Therapy

IVIG• Probably same effects as plasma

exchange or even superior • More available, less side effects• 2 g/ Kg over 2-4 days• Caution: early transient relapse

after IVIG administration

The Cochrane Database of Systematic Reviews 2006Intravenous immunoglobulin for Guillain-Barre

syndromeHughes RAC, Raphael J-C, Swan AV, van Doorn PA

• 6 RCT’s, 536 patients )mostly adults(• Plasma exchange vs IVIG• No statistically significant difference in

primary and secondary outcome• Regimen: no significant difference

between 5 days and 2 days• 3 studies including 75 children

suggested that IVIG significantly hasten recovery compared with supportive care.

Immune globulins are effective in severe pediatric Guillain-Barre syndrome.

• 26 children,Prospective, no control • All bedridden, 2 needed artificial ventilation• All treated with IVIG 2g/kg in 2 days• No adverse effects• 25 improved in 1-2 grades in GMDS within 2

weeks• 18 recovered by 2 weeks• The rest recovered within 4 months• Rapid improvement compared with the

natural history of GBS.

Neonatal Guillain-Barre syndrome.

al-Qudah AA, Shahar E, Logan WJ, Murphy EG.

Department of Pediatrics; Hospital for Sick Children, Toronto, Ontario, Canada.

A term female infant had the clinical manifestations and accompanying electrophysiologic studies to fulfill the criteria of Guillain-Barre syndrome. At birth, she presented with generalized hypotonia, paucity of lower limb movements, and diminished muscle stretch reflexes. At 3 weeks of age, motor nerve conduction studies demonstrated evidence of demyelination and axonal involvement. Progressive clinical improvement was observed beginning at the age of 2 weeks with subsequent normalization of clinical examinations and nerve conduction studies. To our knowledge, this patient is the youngest reported with Guillain-Barre syndrome.
