The course of multiple sclerosis cases with extremely high gamma-globulin values in the cerebrospinal fluid.

40 selected cases of multiple sclerosis (MS) with extremely high gamma-globulin values in the cerebrospinal fluid (CSF) (over 25 rel%, upper normal limit 7.5 rel%) were matched with the same number of MS patients with normal CSF findings. Surprisingly, no definite relationship could be shown between the amount of CSF gamma-globulins and the various clinical criteria in MS, such as age, type of progression, duration of illness, remission, extent of plaques and gravity of the disease.
