In an attempt to decrease catheter drainage of pancreatic pseudocysts, a combined regimen of percutaneous drainage and administration of octreotide acetate was used in eight symptomatic patients. Indications for the combined therapy were pseudocyst recurrence (four patients), pancreatic fistula from percutaneous drainage (two patients), or elective treatment to restrict pancreatic drainage. Octreotide acetate was administered subcutaneously in doses of 50-1,000 micrograms three times a day. The drug was well tolerated and produced only limited adverse effects in four patients: pain at the injection site, hypoglycemia, diarrhea, headaches, and lower-extremity edema (more than one adverse effect was experienced by each patient). The combined use of percutaneous drainage and administration of octreotide was effective in seven patients and failed in one patient who had distal pancreatic duct occlusion. In five patients, catheter drainage decreased to no measurable amount by a mean of 13.8 days. These results suggest octreotide is effective in decreasing the output from pancreatic pseudocysts drained percutaneously.

A 26-yr-old woman with type 1 diabetes and severe symptomatic autonomic neuropathy was treated with the long-acting somatostatin analogue Sandostatin LAR for intractable diarrhea. Her diarrhea had previously been successfully managed with three daily injections of octreotide without adverse consequences. She was given a single dose of Sandostatin LAR and within 2 weeks reported the development of increasingly frequent and severe headaches. Three weeks after the injection, she was admitted to hospital with severe hypertension, which eventually resolved with the administration of antihypertensive agents. No other underlying cause of the hypertension was discovered. Rechallenge of the patient with octreotide resulted in a transient hypertensive episode, which lasted 3 h. Severe hypertension, therefore, seems to be a possible adverse effect of treatment of diabetic diarrhea with somatostatin analogues, which should be used with great caution in subjects with severe autonomic dysfunction.

A European multicentre, open-label 12-month study with Sandostatin LAR administered intramuscularly at 4-week intervals was initiated in 151 acromegalics responsive to octreotide. All patients received 3 injections of the 20 mg dose, following which the dose was adjusted to 10 mg in patients with mean 4-hour GH serum concentrations below 1 microgram/L (N: 29) and to 30 mg in patients with concentrations above 5 micrograms/L (N: 22). The GH level suppression was significant in the 20 mg dose group (p < 0.01) and for all 151 patients (p < 0.004), and was consistently maintained in all patients for the duration of the study. The suppression of the mean serum GH concentration to below 2.5 micrograms/L was recorded in 69.8% of patients at the endpoint treatment with Sandostatin LAR and 65.8% during prior treatment with Sandostatin s.c. A consistent suppression of serum IGF-I levels was also achieved. The number of patients with headache, fatigue, perspiration, joint pains and paresthesias had decreased significantly (p < 0.05) after the 6t]h injection of Sandostatin LAR vs. previous s.c. treatment. No patient discontinued the study because of drug-related adverse events. The most frequently reported adverse events were mild diarrhea, abdominal pain and flatulence. The local tolerability was very good. No impairment of safety hematology, biochemistry and thyroid function tests and no increased incidence of gallstone formation was recorded. Well tolerated and at least as efficacious as the s.c. formulation, Sandostatin LAR might become an alternative primary treatment to pituitary surgery and radiotherapy.

Patients with acromegaly, who are not cured after transsphenoidal adenomectomy, may be treated with external irradiation and/or octreotide injections. Recently, a long-acting formulation of octreotide (Sandostatin LAR has become available in clinical practice. We assessed the effects of treatment with this long-acting octreotide in 18 consecutive patients with acromegaly treated in our center, who had persistent signs and symptoms of acromegaly despite transsphenoidal surgery with (n=7) or without irradiation (n=11). Twelve had already been treated with regular Sandostatin for a period of 0.5-8 years in dosages of 3 x 50 to 3 x 300 mcg s.c. (median daily dose 300 mcg). All patients started with i.m. injections of 20 mg Sandostatin LAR every 4 weeks. In the patients who started treatment with octreotide for the first time, mean serum IGF-1 levels (measured by IRMA, Nichols Diagnostics) decreased from 634+/-229 to 255+/-88 ng/ml after 3 months, 271+/-81 ng/ml after 1 year and 263+/-97 ng/ml after 2 years (all P<0.05), while random GH levels (DELFIA, Wallac) decreased from 6.6 (range 3.1-67.0) to 2.1 (0.5-3.1) mU/l after 2 years (P<0.05). In the 12 patients who had already been treated with octreotide, mean IGF-1 also fell, from 367+/-193 to 331+/-195 ng/ml (P=0.023) after 3 months, to 342+/-191 ng/ml after 1 year and 277+/-169 ng/ml (P=0.002) after 2 years, while random GH levels decreased from 4.5 (1.1-46) mU/l at baseline to 2.1 (0.4-23.0) after 2 years (P=0.003). Therefore, the average decrease of IGF-1 was 10% after 3 months and 25% after 2 years. One patient had a decrease of less than 5% (but her IGF-1 was normal, 193 ng/ml), and one patient showed no response to both regular and long-acting Sandostatin (ave. IGF-1, 755 ng/ml). No specific side-effects occurred. One patient chose to return to t.i.d. injection of regular octreotide because of slight worsening of her complaints of headache despite normal IGF-1 levels. All other patients favoured continuation of the monthly injections. In six patients, the dose had to be increased to 30-40 mg monthly because the IGF-1 levels still remained elevated. Sandostatin LAR may be considered a great improvement for the treatment of patients with (symptomatic) acromegaly.

The authors report clinical observations in 12 acromegalic patients treated with long-acting octreotide (Sandostatin LAR, Novartis, 20 mg intramuscular injection per 28 days administered for 6-36 months). Clinically and hormonally active acromegaly was evidenced in all patients by the presence of typical clinical symptoms, increased serum growth hormone and insulin-like growth factor I concentrations, and by non-suppressible serum growth hormone levels after oral glucose administration. In all patients previous treatments (transsphenoidal surgery, pituitary irradiation and bromocriptine therapy) were uneffective or contraindicated, or they were refused by the patients. Octreotide test (Sandostatin, Novartis, 100 g subcutaneously) performed in all patients before treatment precisely predicted the hormonal effectiveness of long-acting octreotide treatment. Three-six months after therapy serum growth hormone levels decreased from 13.6 +/- 3.9 ng/ml (mean +/- SD) to 3.4 +/- 1.7 ng/ml, while insulin-like growth factor I concentrations decreased from 483 +/- 127 ng/ml to 248 +/- ng/ml. Of the 12 patients 7 (58%) had serum growth hormone levels considered as safe values (< 2.5 ng/ml), whereas in 9 patients (75%) serum insulin-like growth factor I concentrations returned to age- and sex-matched normals. Repeat pituitary magnetic resonance imaging performed in 8 patients treated longer than 1 year revealed a decrease of tumor size in 3 patients (37%). There was a considerable clinical improvement during treatment: severe headache, which was present in most patients, as well as perspiration, joint pain, swelling of extremities, and weakness markedly decreased or disappeared. These results indicate that long-acting octreotide offers a very effective treatment of choice in acromegalic patients in whom other previous therapies were ineffective, contraindicated, or refused.
