Abstract:
Visibility of the nailfold vascular plexus has shown promise as a genetically transmitted marker for liability to schizophrenia. To assess whether this marker is specifically associated with negative or positive symptoms of schizophrenia, we reanalyzed patient data collected 20 years ago, well before interest in the negative/positive symptom distinction. Eighty-four patients, who retrospectively met DSM-III-R criteria for schizophrenia, had been rated for plexus visualization score (PVS) and independently interviewed using the Mental Status Schedule (MSS). Content scales were derived from the MSS to assess negative, positive, and affective symptoms. There was a highly significant correlation between PVS and negative symptoms (including verbal, motor, cognitive and motivational deficits), but not between PVS and positive or affective symptoms. These findings indicate that the negative symptoms of schizophrenia are due to a disease process biologically distinguishable from those causing positive symptoms and that plexus visibility is a risk marker for this pathology.

Abstract:
A group of 17 white male chronic schizophrenic subjects were divided on the basis of plexus visualization score (PVS). High and low PVS subjects were compared to each other and to low PVS controls on measures of platelet monamine oxidase (MAO), rbc catechol-o-methyl transferase (COMT), and plasma dopamine-beta-hydroxylase (D beta H). There were no differences between high and low PVS subjects on any biochemical variable. Schizophrenic subjects had lower platelet MAO activity than controls. Platelet MAO and rbc COMT were significantly correlated in schizophrenic subjects.
