Beneficial effects of acarbose on familiar hypertriglyceridemias.

Abstract Elevated serum triglyceride levels may be related to the following clinical features: increased blood coagulation and viscosity, increased serum fibrinogen levels, decreased fibrinolysis, and for serum levels over 1000 mg/dl, a strong increase of acute pancreatitis rate. Pharmacological choice among the numerous drugs to treat hypertriglyceridemias is currently debated. Our study was aimed to assess the therapeutic efficacy of acarbose in the treatment of non-diabetic subjects, affected by familiar hypertriglyceridemia (FH). We studied 18 non-diabetic patients (10 males, 8 females; mean age 57.61+/-6.85 years) without family history of diabetes mellitus affected by familiar hypertriglyceridemia. The study protocol planned a treatment period of 20 weeks, divided into five 4-week courses and made up as follows: diet plus acarbose therapy (4 weeks); diet therapy alone (4 weeks) alternatively. In the second and fourth 4-week courses diet plus acarbose were administered, while diet therapy alone was administered in the first, third, and fifth 4-week courses. Acarbose doses consisted of 50 mg (1/2 pill) twice daily. Mean serum triglyceride levels, after first month of dietary treatment, underwent a significant reduction from 481.5 +/- 67.1 mg/dl to 389.5 +/- 62.7 mg/dl, even if they did not reach the optimal levels to keep on the dietary therapy alone. After the first month of treatment with acarbose associated to diet, we observed a further reduction of serum triglycerides levels (p = 0.02). When diet alone was administered, mean triglyceride serum levels underwent a significant enhancement (p = 0.003). Restarting for the second time the association treatment, we observed a noteworthy reduction of mean serum triglyceride levels (p = 0.0001). Acarbose acts on the pathogenesis of FH, lowering the production of endogenous triglycerides. Our data suggested that acarbose can be considered a valid therapeutic tool in the treatment of familiar hypertriglyceridemias, also in non-diabetic patients.
