Abstract: | Liquor:serum quotients of IgG and albumin in patients with meningism, meningitis and multiple sclerosis have been studied. Abnormal quotients indicative of disturbed blood-brain barrier function and/or intrathecal IgG synthesis were found in various proportions of all 3 groups of patients. In some patients with aseptic meningitis and meningism, the abnormal quotients were comparable with those found in patients with multiple sclerosis. The reason for this is unknown. An unspecific reaction to febrile illness may be involved. As a consequence, the findings of abnormal liquor:serum quotients of IgG and albumin should be evaluated with great caution in patients with recent or present febrile illness. |
