title: Effect of dietary omega-3 fatty acids on high-density lipoprotein apolipoprotein AI kinetics in type II diabetes mellitus.
abstract: The effect of a dietary fish oil supplementation on metabolism of HDL was studied in type II diabetes mellitus. Endogenous labeling of HDL-apo AI was performed using a 14 h primed infusion of D3-leucine in five diabetic patients before and 2 months after treatment with maxEPA(R). Isotopic enrichment curves were analyzed using a monoexponential function. After treatment, plasma cholesterol level remained unchanged (205.4+/-41.9 vs. 206.8+/-30.7 mg/dl, NS), whereas plasma triglycerides were decreased (155.4+/-67.9 vs. 202.6+/-32.2 mg/dl, P=0.06). Plasma apo AI was similar under maxEPA(R) (116.0+/-25.6 vs. 111.8+/-25.4 mg/dl, NS), and HDL-cholesterol and HDL-triglycerides were also not markedly changed (30.2+/-10.0 vs. 27.1+/-10 mg/dl, and 15.3+/-9.8 vs. 19.2+/-10.4 mg/dl, NS). HDL-apo AI fractional catabolic rate (FCR) and absolute production rate (APR) were significantly decreased after treatment with maxEPA(R) (0.27+/-0.09 vs. 0.37+/-0.08 pool day, P<0.05, and 12.1+/-2.8 vs. 16.1+/-3.3 mg/kg per day, P<0.05). These findings showed an effect of maxEPA(R) on kinetics of apolipoprotein AI in type II diabetes mellitus, probably linked to changes in plasma triglyceride level.
