The cerebrospinal fluid (CSF) concentrations of somatostatin and neuropeptide Y were investigated by use of radioimmunoassay in patients suffering from chronic progressive multiple sclerosis. The somatostatin level was significantly decreased in the CSF of patients with multiple sclerosis compared to the control group. The magnitude of this change was more pronounced in patients with severe clinical symptoms of the illness. The CSF neuropeptide Y concentration did not differ from the control values. These findings suggest a selective involvement of somatostatin neurotransmission in multiple sclerosis.
