1. Somatostatin displays a regulatory function on several aminergic neurotransmitters, including dopamine. In addition, decreased CSF levels of the peptide has been found in Schizophrenia and other neuropsychiatric disorders. 2. In the present work, we have investigated levels of plasmatic somatostatin in a sample of 50 schizophrenic patients compared with a normal control group. 3. Somatostatin was increased in the patient group (p less than 0.01) as a whole but statistical analysis revealed that the increase was associated with the presence of positive symptoms (Factorial Analysis) with a significant correlation, specially with delusion and hallucination scores in the Andreasen rating scales.

A patient with a macroprolactinoma and extrasellar extension was treated by incomplete transfrontal surgery, external irradiation and additional bromocriptine (Br) treatment. After 4 years, partial bromocriptine resistance developed (a rare occurrence) together with the appearance of intracranial metastases. 123I-Iodobenzamide was helpful in evaluating the dopamine D2 receptor status of the metastatic tumour both in vivo using single-photon emission computed tomography (SPECT) and in vitro. Prolactin release by the cultured metastatic tumour cells was more potently inhibited by CV 205-502 than by bromocriptine. The patient, treated by surgery, irradiation and CV 205-502, developed a ptosis of the left eye and a transient psychiatric delusional state, the latter probably an effect of the dopamine agonist. As the right frontal metastasis was markedly positive on SPECT with 111In-SMS, somatostatin treatment was added to the CV 205-502.
