[Frequency of immunologic disorders in acute schizophrenia]

Immunological examinations in schizophrenic patients have shown that there are many alterations in both arms of the immune system, i.e. cellular and humoral activities. The results are quite heterogeneous, as not even all schizophrenics show these pathological changes. Immunological findings are assumed to be etiopathogenetically related to the disease process or to be an epiphenomenon. The present study supposes that immunological alterations as they can be found during the course of schizophrenia may be an indicator for somatic vulnerability or an epiphenomenon. 60 male inpatients, fulfilling DSM-IV criteria of schizophrenia where examined during their acute phases of psychosis and during their phases of clinical improvement, by means of a serological profile including cellular and humoral parameters. The control group consisted of 42 healthy male volunteers. It was the aim of this study to find out if there were (a) overall differences in the immune profiles between patients and control group and (b) differences between different categories of schizophrenic disorder. During the acute phase nearly half of the schizophrenic patients showed pathologic immunological parameters, whereas none of the controls did. During the phase of clinical improvement the number of patients with normal immunological findings predominated. Furthermore there was a difference between the Paranoid and the Disorganized Subtype, the latter showing more immunological abnormalities. The results of this study give further support to the hypothesis that immunological aberrations should not be seen as closely etiopathogenetically related to schizophrenic disorders, but rather as an epiphenomenon (e.g. as a stress marker) and/or as indicators for somatic vulnerability.
