据报道,血浆高密度脂蛋白胆固醇(HDL-C)水平与甘油三酯(TG)水平和餐后脂血症程度呈负相关,因为低HDL-C伴高TG水平的受试者餐后对脂肪负荷的反应往往增加。然而,关于低HDL-C和正常空腹TG(低α脂蛋白血症[低α])受试者餐后对脂肪负荷的反应的信息有限。我们给6名低α患者和6名年龄匹配的对照组口服脂肪负荷(70 g/m2体表面积)。每2小时测量一次血浆脂质、脂蛋白水平和富甘油三酯脂蛋白质量(TRLs: Sf bbb100和Sf 20-100),持续8小时。空腹组间Sf - bbb100和Sf - 20-100 trl的质量和化学成分无显著差异;低α血症患者餐后Sf -100、Sf -100 TRLs(平均+/- SD)显著降低(200.4 +/- 64.8 mg/dL vs 110.6 +/- 50.9 mg/dL;方差分析,F检验,p = 0.04)。在低α受试者中,餐后Sf -100 trl的TG含量较低,胆固醇和磷脂含量较高(p < 0.001),而Sf - 20-100 trl的胆固醇和磷脂含量较高,蛋白质含量相对较低(p = 0.002)。(摘要删节250字)
The plasma level of high density lipoprotein cholesterol (HDL-C) has been reported to be inversely correlated with the level of triglycerides (TGs) and the magnitude of postprandial lipemia because subjects with low HDL-C accompanying high TG levels often have an increased postprandial response to a fat load. However, information is limited regarding the postprandial response to a fat load in subjects with low HDL-C and normal fasting TG values (hypoalphalipoproteinemia [hypoalpha]). We administered an oral fat load (70 g/m2 of body surface area) to six subjects with hypoalpha and six aged-matched control subjects. Plasma levels of lipids and lipoproteins and the mass of triglyceride-rich lipoproteins (TRLs: Sf > 100 and Sf 20-100) were measured every 2 hours for 8 hours. The mass and chemical composition of Sf > 100 or Sf 20-100 TRLs were not different between the fasting groups; postprandial Sf > 100 but not Sf 20-100 TRLs (mean +/- SD) was significantly lower in subjects with hypoalpha (200.4 +/- 64.8 mg/dL versus 110.6 +/- 50.9 mg/dL; analysis of variance, F test, p = 0.04). In the hypoalpha subjects, the compositions of postprandial Sf > 100 TRLs were TG poor and cholesterol and phospholipid enriched (p < 0.001) while the Sf 20-100 TRLs were enriched in cholesterol and phospholipid but relatively protein depleted (p = 0.002).(ABSTRACT TRUNCATED AT 250 WORDS)
