Objectives
Low level inflammatory Mild Encephalitis (ME) mechanisms were suspected in a subgroup of treatment resistant hospitalised affective and schizophrenic spectrum disorder patients.Methods
We analysed albumin, IgG, IgA, IgM, oligoclonal IgG and specific antibodies in paired cerebrospinal fluid (CSF) and serum samples from patients with affective (n=24) or schizophrenic spectrum disorders (n=39). Numerical and graphical interpretation of CSF protein data was performed by Reibergrams with reference to a large control group (n= 4100).
Results
In 41 % of the psychiatric patients (n=63) we observed CSF pathologies: 14 % displayed intrathecal humoral immune responses, 10 % slightly increased CSF cell counts (5-8/μL) and 29 % had moderate blood-CSF barrier dysfunctions, in 24 % as the only pathological sign with normal IgG, IgA and IgM concentrations in CSF (p= 0.9 testing the null hypothesis for intrathecal synthesis with reference to Qmean of the reference group). In the affective (n= 24) spectrum 20 % displayed a systemic immune reaction as detected by oligoclonal IgG. In probable 6 % of virusspecific, bacterial or autoimmune associated disorder with CNS involvement. Elevated CSF neopterin concentration in 34 % of the patients was interpreted as an increased release from astrocytes or from other glia cells.
Conclusion
The low level immune response and barrier dysfunctions are discussed on the base of a ME pathomechanism in subgroups of psychiatric patients. CSF analysis is shown to be a useful diagnostic tool for differential diagnosis in psychiatric diseases.
