Effects of octreotide on lipid metabolism in acromegaly.
Hypertriglyceridemia is the most frequent modification of lipid metabolism observed in acromegaly. The somatostatin analog, octreotide (Sandostatin), widely used in the treatment of acromegaly, is able to produce a decrease in levels of growth hormone (GH), insulin, and Insulin-like Growth Factor 1 (IGF1). We have attempted to evaluate the influence of this treatment on the lipid status of acromegalic patients. Seventeen patients with active acromegaly were treated with octreotide, 100 to 500 micrograms/injection subcutaneously three times daily. The levels of fasting serum triglycerides (TG), total cholesterol, High Density Lipoprotein (HDL) cholesterol and IGF1, as well as mean plasma GH and insulin levels during a diurnal profile, were evaluated before and after three months of octreotide therapy. GH, insulin and IGF1 decreased by 61%, 42% and 36% respectively (p less than 0.05). Mean levels (+/- SEM) of TG and total cholesterol fell from 2.2 +/- 0.4 mmol/l to 1.6 +/- 0.3 mmol/l (p less than 0.05) and 6.4 +/- 0.39 mmol/l to 5.6 +/- 0.27 mmol/l (p greater than 0.05), respectively. There was no correlation between triglyceride decrease and hormonal changes or clinical status (BMI, age, sex). In conclusion, the administration of octreotide over a three month period to acromegalic patients is associated with a decrease in TG levels.
