- Background and aims: Hepatic lipase (HL) catalyzes the hydrolysis of triglycerides and phospholipids from lipoproteins, and promotes the hepatic uptake of tipoproteins. A common G-250A polymorphism in the promoter of the hepatic lipase gene (LIPC) has been described. The aim was to study the effects of the G-250A polymorphism on HL activity, serum lipid profile and insulin sensitivity. Methods and results: Altogether 151 healthy subjects (age 49 +/- 8 years, BMI 26.5 +/- 3.0 kg/m(2)) were randomly assigned for 3 months to an isoenergetic diet containing either a high proportion of saturated fatty acids (SFA diet) or monounsaturated fatty acids (MUFA diet). Within groups there was a second random assignment to supplements with fish oil (3.6 g n-3 FA/day) or placebo. At baseline, the A-250A genotype was associated with high serum LDL cholesterol concentration (P = 0.030 among three genotypes). On the MUFA diet carriers of the A-250A genotype presented a greater decrease in LDL cholesterol concentration than subjects with other genotypes (P = 0.007 among three genotypes). The rare -250A allele was related to Low HL activity (P < 0.001 among three genotypes). The diet did not affect the levels of HL activity among the genotypes. Conclusion: The A-250A genotype of the LIPC gene was associated with high LDL cholesterol concentration, but the MUFA-enriched diet reduced serum LDL cholesterol concentration especially in subjects with the A-250A genotype.

- OBJECTIVE - The efficacy and Safety of adding liraglutide (a glucagon-like peptide-1 receptor agonist) to Metformin were compared with addition of placebo or glimepiride to metformin in subjects previously treated With oral antidiabetes (OAD) therapy. RESEARCH DESIGN AND METHODS - In this 26-week, double-blind, double-dummy, placebo- and active-controlled, parallel-group trial, 1,091 subjects were randomly assigned (2:2:2:1:2) to once-daily liraglutide (either 0.6, 1.2, or 1.8 mg/day injected subcutaneous ), to placebo, or to glimepiride (4 mg once daily). All treatments were in combination therapy with metformin (1g twice daily). Enrolled subjects (aged 25-79 years) had type 2 diabetes, A1C of 7-11% (previous OAD monotherapy for >= 3 months) or 7-10% (previous OAD combination therapy for >= 3 months), and BMI <= 40 kg/m(2). RESULTS - A1C Values were significantly reduced in all liraglutide groups versus the placebo group (P<0.0001) with mean decreases of 1.0% for 1.8 mg liraglutide, 1.2 mg liraglutide and glimepiride and 0.7% for 0.6 mg liraglutide and -,in increase of 0.1% for placebo. Bod weight decreased in all liraglutide groups (1.8-2.8 kg) compared with an increase in the glimepiride group (1.0 kg; P < 0.0001). The incidence of minor hypoglycemia with liraglutide (similar to 3%) was comparable to that, with placebo but less than that with glimepiride (1,7%; P < 0.001). Nausea was reported by 11-19% of the liraglutide-treated subjects versus 3-4% in the placebo and glimepiride groups. The incidence of nausea declined over time. CONCLUSIONS - In subjects with type 2 diabetes, once-daily liraglutide induced similar glycemic control, reduced body weight, and lowered the Occurrence of hypoglycemia compared with glimepiride, when both had background therapy of metformin.
