Guillain-Barré syndrome with exaggerated pleocytosis and anti-GM1 ganglioside antibodies

Anti-GM1 antibodies in patients with Guillain-Barré syndrome.

Anti-GM1 antibodies were measured in 22 patients with the Guillain-Barré syndrome (GBS) and compared with anti-GM1 antibody activity in patients with other neurological or immunological diseases and in normal subjects. Four out of 22 patients with GBS had raised IgM, IgG, or IgA anti-GM1 antibody activities. All four patients were tetraparetic with only minimal or no sensory deficit. Three of t...

Detection of Anti-Ganglioside Antibodies in Guillain-Barre Syndrome

The presence of Mycoplasma pneumoniae infection and GM1 ganglioside antibodies in Guillain-Barré syndrome.

INTRODUCTION Guillain-Barré syndrome (GBS) is an autoimmune disorder affecting the peripheral nervous system, usually triggered by an acute infection. GBS patients are known to have antecedent bacterial infections associated with auto-antibodies to various gangliosides. This investigation aimed to evaluate GBS patients for serological evidence of Mycoplasma pneumoniae infection and anti GM1 gan...

Individual Restriction Of Fine Specificity Variability In Anti-GM1 IgG Antibodies Associated With Guillain-Barré Syndrome

Elevated titers of serum antibodies against GM1 ganglioside are associated with a variety of autoimmune neuropathies. Much evidence indicates these autoantibodies play a primary role in the disease processes, but the mechanism for their appearance is unclear. We studied the fine specificity of anti-GM1 antibodies of the IgG isotype present in sera from patients with Guillain-Barré syndrome (GBS...

Increased circulating T cell reactivity to GM1 ganglioside in patients with Guillain-Barré syndrome.

This study was performed to determine whether increased ganglioside-specific T cell reactivity can be detected in the peripheral blood of patients with Guillain-Barre syndrome (GBS) and chronic inflammatory demyelinating polyradiculoneuropathy (CIDP). T cell responsiveness to the gangliosides GM1, GM3, GD1a, GD1b, GD3, GT1b, GQ1b and sulphatide was assessed in peripheral blood mononuclear cells...
