T cell activation in Guillain-Barré syndrome and in MS: elevated serum levels of soluble IL-2 receptors.

Author information

Guillain-Barré syndrome (GBS), chronic idiopathic demyelinating polyradiculoneuropathy (CIDP), and multiple sclerosis (MS) are disorders with presumed immunopathogenesis. To obtain evidence for T cell activation, we determined serum concentrations of soluble interleukin-2 receptors (sIL-2 R) in 50 patients with GBS, 24 with CIDP, and 54 with MS. Both in GBS and clinically active MS sIL-2 R levels were markedly increased compared with those in patients with other neurologic diseases. Four of 24 CIDP patients had abnormally increased sIL-2 R concentrations. sIL-2 R concentrations decreased with clinical improvement in serial samples taken from GBS patients, but were not otherwise correlated with disease severity. These data establish that T cells are activated in GBS and some patients with CIDP, and corroborate earlier evidence that activated T cells are circulating in the blood of MS patients.
