Plasma benzylamine oxidase (BzAO) activity was analysed in a group of 40 schizophrenic patients and compared with that of healthy controls. Although plasma BzAO was significantly decreased in schizophrenics as a whole, when patients were divided into type I (favourable course) and type II (poor course) it was found that the reduced BzAO activity was only observed in type I. Several clinical features were associated with a low BzAO level. The clinical and biological significance of the identification of a biochemical alteration in a subgroup of schizophrenic patients is discussed, and we suggest that the possibility of BzAO being a marker for prognosis in schizophrenia should be further investigated.
