Growth hormone responses to apomorphine HCl in schizophrenic patients on drug holidays and at relapse
JM Cleghorn, GM Brown, PJ Brown, RD Kaplan, SW Dermer, DJ MacCrimmon and J Mitton
In nine schizophrenic patients on drug holiday, growth hormone (GH)
response to apomorphine HCl 0.75 mg (APO) was compared with normal control
data. Patients were tested at two month intervals for up to 14 months.
Seven patients relapsed, and of these, five had exaggerated GH responses to
APO at that time. Of these five, three had exaggerated GH responses to APO
prior to clinical deterioration. Further work is required to determine
whether this test can be a useful predictor of relapse.
