Postprandial changes in the distribution of apolipoprotein AIV between apolipoprotein B- and non apolipoprotein B-containing lipoproteins in obese women.
Metabolism 2003; 52(12):1537-41M

Abstract

Plasma apolipoprotein AIV (apo AIV) level has been shown to be a good marker of triglyceride changes after a high-fat diet. However, the distribution of apo AIV between apo B- and non-apo B-containing lipoproteins (Lp) during the postprandial state has not been described as well as the influence of obesity on this distribution. Our aim was to study the influence of parameters related to obesity and insulin resistance on the postprandial changes in apo AIV-containing Lp after a high-fat meal in obese women. Twenty-three overweight or obese women (body mass index [BMI] ranging from 29.1 and 64.0 kg.1 m(-2)), for whom blood samples were taken after fasting overnight, participated in the study. Thirteen of these obese women were given a fatty meal and, in this case, blood samples were taken at fast and 30 minutes, 1, 2, 4, and 6 hours after ingestion of the fat meal. Apo AIV-containing particle families, Lp B:AIVf (family [f] of particles containing at least apo B and apo AIV) and Lp AIV non-Bf (family [f] of particles containing apo AIV, but free of apo B) were quantified by sandwich enzyme-linked immunosorbent assay (ELISA). When fasting, Lp B:AIVf and Lp AIV non-Bf did not correlate with any of the parameters related to obesity and insulin resistance, if one excepts a positive correlation between HDL-cholesterol (HDL-C) and Lp AIV non-Bf. Postprandial lipemia was associated with a trend towards an increase in the plasma levels of apo AIV-containing Lp 6 hours after fat ingestion. The postprandial peak of Lp B:AIVf and Lp AIV non-Bf occurred 2 hours after the triglyceride peak. The distribution between apo B- and non-apo B-containing Lp did not change after ingestion of the fat meal, if one excepts a tendancy towards a lower ratio of bound and nonbound forms at 8 hours. Fasting plasma Lp B:AIVf concentration correlated with the area under the curve (AUC) of plasma triglycerides (beta = 0.11, P <.02). In a multivariate analysis, BMI (beta = 51.85, P <.001), fasting triglycerides (beta = 431.08, P <.01), and low-density lipoprotein-cholesterol (LDL-C) (beta = 2638.57, P <.005) were independent and positive determinants of the AUC of Lp AIV non-Bf, while waist circumference (beta = -23.94, P <.001), cholesterol (beta = -1655.02, P <.01), and systolic blood pressure (beta = -6.34, P <.05) were negative and independent determinants of this AUC. Fasting Lp B:AIVf may represent a good marker of the postprandial triglyceride increase in obese women. Changes in apo AIV concentrations in apo B- and non-apo B-containing Lp after a fat meal depend mainly on the degree of obesity rather than on insulin resistance. This effect is more obvious for Lp AIV non-Bf than for Lp B:AIVf.
