Evidence of Intrathecal Immunoglobulin Synthesis in Stroke: A Cohort Study
JAMA Neurology, 03/16/2012Pruss H et al.
The strong association between cerebrospinal fluid (CSF)–specific immunoglobulin synthesis and stroke suggests a role in the development of cerebral ischemia and might constitute an immunologically defined stroke subgroup.
Patients (n = 318) with stroke who were undergoing lumbar puncture during diagnostic workup and 79 control patients.
Cerebrospinal fluid-specific immunoglobulin (IgG, IgM, and IgA) synthesis was significantly (P < .001) more frequent after stroke (24.8%) compared with the incidence in age- and sex-matched controls (2.5%).
Furthermore, 31.3% of stroke patients demonstrated blood-brain barrier dysfunction and 18.1% displayed pleocytosis.
