Signs and symptoms

The disorder is characterized by symmetrical weakness which usually affects the lower limbs first, and rapidly progresses in an ascending fashion. Patients generally notice weakness in their legs, manifesting as "rubbery legs" or legs that tend to buckle, with or without dysesthesias (numbness or tingling). As the weakness progresses upward, usually over periods of hours to days, the arms and facial muscles also become affected. Frequently, the lower cranial nerves

Cause

All forms of Guillain–Barré syndrome are due to an immune response to foreign antigens (such as infectious agents) that is mistargeted at host nerve tissues instead. The targets of such immune attack are thought to be gangliosides, compounds naturally present in large quantities in human nerve tissues. The most common antecedent infection is the bacterium Campylobacter jejuni

Influenza

Becoming infected with influenza increases both the risk of developing GBS and the risk of death (up to 1 in 10,000 who get influenza will die from it). While influenza vaccines have sometimes been suspected to raise the incidence of GBS, the evidence is equivocal, as shown below. Moreover, the highest level of suspected risks from the influenza vaccine is less than one-tenth the risk from the influenza disease itself, as discussed in more detail in the next section. The risk of GBS following influenza vaccination is about one case per 1 million vaccines given.

Influenza vaccine

GBS may be a rare side-effect of influenza vaccines; a study of the Vaccine Adverse Event Reporting System

The 1976 swine flu outbreak, also known as the swine flu fiasco, or the swine flu debacle, was a strain of H1N1 influenza virus that appeared in 1976. Infections were only detected from January 19 to February 9, and were not found outside Fort Dix. The outbreak is most remembered for the mass...

(By comparison, the average flu season kills around 30,000 people in the United States). However, the role of the vaccine even in those 25 cases in 1976 has remained unclear, partly because GBS had an unknown but very low incidence

 rate in the general population making it difficult to assess whether the vaccine was really increasing the risk for GBS. Later research has pointed to the absence of, or only a very small increase in, the GBS risk due to the 1976 swine flu vaccine. Furthermore, the GBS may not have been directly due to the vaccine but to a bacterial contamination of the 1976 vaccine.

Since 1976, no other influenza vaccines have been linked to GBS, though as a precautionary principle

From October 6 to November 24, 2009, the U.S. CDC, through the VAERS reporting system, received ten reports of Guillain-Barré syndrome cases associated with the H1N1 vaccine and identified two additional probable cases from VAERS reports (46.2 million doses were distributed within the U.S. during this time).

's Emerging Infections Programs (EIP) calculates the rate of GBS observed in patients who previously received the 2009 H1N1 influenza vaccination is an excess of 0.8 per million cases, which is on par with the rate seen with the seasonal trivalent influenza vaccine.

Although one review gives an incidence of about one case per million vaccinations, a large study in China, reported in the NEJM covering close to 100 million doses of vaccine against the 2009 H1N1 "swine" flu found only eleven cases of Guillain-Barré syndrome (0.1 per million) total incidence in persons vaccinated, actually lower than the normal rate of the disease in China, and no other notable side effects; "The risk-benefit ratio, which is what vaccines and everything in medicine is about, is overwhelmingly in favor of vaccination."

Diagnosis

The diagnosis of GBS usually depends on findings such as rapid development of muscle paralysis, areflexia, absence of fever, and a likely inciting event. Cerebrospinal fluid analysis (through a lumbar spinal puncture) and electrodiagnostic tests of nerves and muscles (such as nerve conduction studies) are common tests ordered in the diagnosis of GBS.

Typical CSF findings include albumino-cytological dissociation. As opposed to infectious causes, this is an elevated protein level (100–1000 mg/dL), without an accompanying increased cell count pleocytosis. A sustained increased white blood cell count may indicate an alternative diagnosis such as infection.

Once the patient is stabilized, treatment of the underlying condition should be initiated as soon as possible. Either high-dose intravenous immunoglobulins (IVIg) at 400 mg/kg for 5 days or plasmapheresis

 can be administered, as they are equally effective and a combination of the two is not significantly better than either alone. Therapy is no longer effective two weeks after the first motor symptoms appear, so treatment should be instituted as soon as possible. IVIg is usually used first because of its ease of administration and safety profile, with a total of five daily infusions for a total dose of 2 g/kg body weight (400 mg/kg each day). The use of intravenous immunoglobulins is not without risk, occasionally causing hepatitis, or in rare cases, renal failure if used for longer than five days. Glucocorticoids have not been found to be effective in GBS. If plasmapheresis is chosen, a dose of 40-50 mL/kg plasma exchange (PE) can be administered four times over a week.

Following the acute phase, the patient may also need rehabilitation to regain lost functions. This treatment will focus on improving ADL (activities of daily living

) functions such as brushing teeth, washing, and getting dressed. Depending on the local structuring on health care, a team of different therapists and nurses will be established according to patient needs. An occupational therapist can offer equipment (such as wheelchair and special cutlery) to help the patient achieve ADL independence. A physiotherapist would plan a progressive training program and guide the patient to correct functional movement, avoiding harmful compensations which might have a negative effect in the long run. There is also some evidence supporting physiotherapy

 in helping patients with Guillain–Barré syndrome regain strength, endurance, and gait quality, as well as helping them prevent contractures, bedsores, and cardiopulmonary difficulties. A speech and language therapist would be essential in the patient regaining speaking and swallowing ability if they were intubated and received a tracheostomy. The speech and language therapist would also offer advice to the medical team regarding the swallowing abilities of the patient and would help the patient regain their communication ability pre-dysarthria. There would also be a doctor, nurse and other team members involved, depending on the needs of the patient. This team contribute their knowledge to guide the patient towards his or her goals, and it is important that all goals set by the separate team members are relevant for the patient's own priorities. After rehabilitation the patient should be able to function in his or her own home and attend necessary training as needed.

Prognosis

Most of the time recovery starts after the fourth week from the onset of the disorder. Approximately 80% of patients have a complete recovery within a few months to a year, although minor findings may persist, such as areflexia. About 5–10% recover with severe disability, with most of such cases involving severe proximal motor and sensory axonal damage with inability of axonal regeneration. However, this is a grave disorder and despite all improvements in treatment and supportive care, the death rate among patients with this disorder is still about 2–3% even in the best intensive care units. Worldwide, the death rate runs slightly higher (4%), mostly from a lack of availability of life support equipment during the lengthy plateau lasting four to six weeks, and in some cases up to one year, when a ventilator is needed in the worst cases. About 5–10% of patients have one or more late relapses, in which case they are then classified as having chronic inflammatory demyelinating polyneuropathy

 (CIDP).

Poor prognostic factors include: 1) age, over 40 years, 2) history of preceding diarrheal illness, 3) requiring ventilator support, 4) high anti-GM1 titre and 5) poor upper limb muscle strength.

Epidemiology

The incidence of GBS during pregnancy is 1.7 cases per 100,000 of the population. The mother will generally improve with treatment but death of the fetus is a risk. The risk of Guillain–Barré syndrome increases after delivery, particularly during the first two weeks postpartum. There is evidence of Campylobacter jejuni
