The effect of subcutaneous infusion versus subcutaneous injections of a somatostatin analogue (SMS 201-995) on the diurnal GH profile in acromegaly.

| Abstract |
Multiple sc injections of a long-acting somatostatin analogue (SMS 201-995) are currently used in the treatment of acromegaly. However, plasma GH concentration often reaches a pathological level (less than 5 micrograms/l) between two injections. In seven patients with active acromegaly we compared, in a short-term trial, the effect of SMS 201-995 administered by continuous sc infusion (50 micrograms and 100 micrograms a day) and by three sc injections (100 micrograms each). In six patients, plasma GH levels were significantly reduced regardless of the mode and dose of treatment (P less than 0.05). However, comparing diurnal profiles, 100 micrograms continuous sc infusion was more effective than discontinuous administration in reducing the number of GH levels above 5 micrograms/l (P less than 0.01). In two patients, continuous infusion was the only way to decrease all plasma GH values below 5 micrograms/l during the diurnal profile determination. Moreover, even when, in a long-term study, the dose of multiple injections was progressively increased to 500 micrograms three times a day, GH levels remained consistently elevated in one of these patients. Thus, in some acromegalic patients continuous sc injection seems currently the most efficient way of treatment with SMS 201-995.
