Quantitative determination of immunoglobulins in CSF and plasma of chronic schizophrenic patients
LE Delisi, DR Weinberger, S Potkin, LM Neckers, DJ Shiling and RJ Wyatt
Immunoglobulins, IgG, IgA and IgM were quantified in cerebrospinal fluid
(CSF) and plasma from chronic schizophrenic patients and controls using an
immunofluorescent antibody technique. A generalized reduction in
immunoglobulin levels was observed in the schizophrenic patients compared
with controls. While this study supports other reports of abnormal immune
functioning in schizophrenia, it failed to replicate previous findings of
elevations in CSF IgG and elevations in serum IgA. The aetiology and
significance of these findings are hypothesized but remain elusive.
