title: Medical management of acromegaly: effects of SMS 201-995 in 30 patients.
abstract: The effect of chronic administration of SMS 201-995, a long acting analogue of somatostatin, has been studied in 30 acromegalic patients (pts). CT-scan showed pituitary adenoma in 20/30 pts, empty sella in 9/30 pts and no sign of pituitary tumor in one case. SMS 201-995 was administered subcutaneously every 8 hours at the daily dose of 150-900 micrograms. Blood samples for GH, insulin and blood glucose were taken hourly from 04:00 to 20:00 h before treatment, after 15 days and then monthly or fortnightly. IGF-I plasma levels were assayed at 08:00 h in the same day as GH determinations. CT-scan controls were carried out after 12-24 months of treatment in 16/20 pts. GH plasma levels were normalized in 16/30 pts after 0.5-9 months of SMS treatment, whereas in 14/30 pts they were reduced by about 50%. In 10/16 pts the CT-scan examination showed a shrinkage of the tumor size of 20-55%, while no variation of the tumor mass was observed in the 2 pts. In conclusion our data show that SMS 201-995 is a very effective medical treatment in acromegalic patients.
