title: Increased level of cerebrospinal fluid beta 2-microglobulin is related to neurologic impairment in multiple sclerosis.
abstract: beta 2-microglobulin was measured in the CSF of 33 MS patients (age range 26-66 years) and compared with the 95% confidence interval determined in an age-matched reference group of 32 patients without neurologic disease. Six MS (18%) had moderately increased concentrations and this subgroup was characterized by severe neurologic impairment according to Kurtzke's expanded disability scale. Increased CSF beta 2-microglobulin concentration in MS may reflect lesion formation.
