          Abstract

          Guillain-Barré syndrome (GBS) is an acute polyradiculoneuropathy, thought to be an autoimmune process. Although cases of GBS have been reported following a wide range of vaccines, a clear association has only been established with the 1976 H1N1 inactivated influenza vaccine.

          Guillain-Barré syndrome.

          Guillain-Barré syndrome consists of at least four subtypes of acute peripheral neuropathy. Major advances have been made in understanding the mechanisms of some of the subtypes. The histological appearance of the acute inflammatory demyelinating polyradiculoneuropathy (AIDP) subtype resembles experimental autoimmune neuritis, which is predominantly caused by T cells directed against peptides from the myelin proteins P0, P2, and PMP22. The role of T-cell-mediated immunity in AIDP remains unclear and there is evidence for the involvement of antibodies and complement. Strong evidence now exists that axonal subtypes of Guillain-Barré syndrome, acute motor axonal neuropathy (AMAN), and acute motor and sensory axonal neuropathy (AMSAN), are caused by antibodies to gangliosides on the axolemma that target macrophages to invade the axon at the node of Ranvier. About a quarter of patients with Guillain-Barré syndrome have had a recent Campylobacter jejuni infection, and axonal forms of the disease are especially common in these people. The lipo-oligosaccharide from the C jejuni bacterial wall contains ganglioside-like structures and its injection into rabbits induces a neuropathy that resembles acute motor axonal neuropathy. Antibodies to GM1, GM1b, GD1a, and GalNac-GD1a are in particular implicated in acute motor axonal neuropathy and, with the exception of GalNacGD1a, in acute motor and sensory axonal neuropathy. The Fisher's syndrome subtype is especially associated with antibodies to GQ1b, and similar cross-reactivity with ganglioside structures in the wall of C jejuni has been discovered. Anti-GQ1b antibodies have been shown to damage the motor nerve terminal in vitro by a complement-mediated mechanism. Results of international randomised trials have shown equivalent efficacy of both plasma exchange and intravenous immunoglobulin, but not corticosteroids, in hastening recovery from Guillain-Barré syndrome. Further research is needed to discover treatments to prevent 20% of patients from being left with persistent and significant disability.

            Population Incidence of Guillain-Barré Syndrome: A Systematic Review and Meta-Analysis

            Population incidence of Guillain-Barré syndrome (GBS) is required to assess changes in GBS epidemiology, but published estimates of GBS incidence vary greatly depending on case ascertainment, definitions, and sample size. We performed a meta-analysis of articles on GBS incidence by searching Medline (1966–2009), Embase (1988–2009), Cinahl (1981–2009) and CABI (1973–2009) as well as article bibliographies. We included studies from North America and Europe with at least 20 cases, and used population-based data, subject matter experts to confirm GBS diagnosis, and an accepted GBS case definition. With these data, we fitted a random-effects negative binomial regression model to estimate age-specific GBS incidence. Of 1,683 nonduplicate citations, 16 met the inclusion criteria, which produced 1,643 cases and 152.7 million person-years of follow-up. GBS incidence increased by 20% for every 10-year increase in age; the risk of GBS was higher for males than females. The regression equation for calculating the average GBS rate per 100,000 person-years as a function of age in years was exp[–12.0771 + 0.01813(age in years)] × 100,000. Our findings provide a robust estimate of background GBS incidence in Western countries. Our regression model may be used in comparable populations to estimate the background age-specific rate of GBS incidence for future studies.

              The spectrum of antecedent infections in Guillain-Barré syndrome: a case-control study.

              To determine which antecedent infections are specifically associated with the Guillain-Barré syndrome (GBS). Infections with many agents have been reported preceding GBS. Some infections are related to specific clinical and immunologic subgroups in GBS. Most agents were reported in case reports and uncontrolled small series of GBS patients only, and their relation to GBS and its subgroups remains unclear. A serologic study for 16 infectious agents in 154 GBS patients and 154 sex- and age-matched controls with other neurologic diseases. Acute phase, pretreatment samples were used from clinically well-defined GBS patients. The seasonal distribution of serum sampling in the GBS and control group was the same. Multivariate analysis showed that in GBS patients, infections with Campylobacter jejuni (32%), cytomegalovirus (13%), and Epstein-Barr virus (10%) were significantly more frequent than in controls. Mycoplasma pneumoniae infections occurred more often in GBS patients (5%) than in controls in univariate analysis. Infections with Haemophilus influenzae (1%), parainfluenza 1 virus (1%), influenza A virus (1%), influenza B virus (1%), adenovirus (1%), herpes simplex virus (1%), and varicella zoster virus (1%) were also demonstrated in GBS patients, but not more frequently than in controls. C. jejuni infections were associated with antibodies to the gangliosides GM1 and GD1b and with a severe pure motor form of GBS. Cytomegalovirus infections were associated with antibodies to the ganglioside GM2 and with severe motor sensory deficits. Other infections were not related to specific antiganglioside antibodies and neurologic patterns. Recent infections with C. jejuni, cytomegalovirus, Epstein-Barr virus, and M. pneumoniae are specifically related to GBS. The variety of infections may contribute to the clinical and immunologic heterogeneity of GBS.
