Acromegaly is a disorder caused by excessive secretion of human growth hormone (GH). Somatostatin and its analogue-prolonged release formulation, lanreotide (Somatuline PR), inhibit the secretion of growth hormone. The aim of this open Phase III study was to investigate the clinical efficacy of lanreotide in the treatment of six acromegalic patients with a mean age of 44±13yr including two patients with diabetes mellitus. All the patients previously received transsphenoidal or transcranial hypophysectomy. Lanreotide was given intramuscularly every 2 weeks at a fixed dose of 30mg for 12 weeks. Serum GH and insulin-like growth factor-I (IGF-I) levels were evaluated before, 2, 6 and 12 weeks after treatment. After 12 weeks of treatment, mean (±SEM) GH levels decreased from 24.8±12.5 to 6.9±3.3ng/ml and mean serum IGF-I levels decreased from 689±282 to 430±216ng/ml. Abdominal ultrasonographic examinations showed no gallbladder stone or bile sand formation before or after the treatment. Three of the patients who did not receive octreotide presented with manifestations of mild gastrointestinal adverse effect such as mild abdominal pain and diarrhea. In conclusion, lanreotide is effective in the treatment of active postoperative acromegaly.
