Abstract:
Accelerated atherosclerosis is not only a frequent complication but also the most common cause of death in patients with chronic renal failure (CRF). Although mechanisms are unclear, disorder of lipid metabolism may be a major factor. Since apolipo-protein (apo) E is known to play a major regulatory role in lipid metabolism, we evaluated apo E genotype in 72 male patients with CRF and compared with that in 194 rnale normal controls. In addition, we measured plasma lipid and apolipoprotein concentrations and evaluated them according to apo E genotype in patients and controls. Apo E genotype was determined with the INNO-LiPA Apo E kit (Innogenetics, Belgium), which is based on reverse hybridization. The results are as follows ; 1) The distribution of the three major apo E alleles in patients with CRF ( e 2: 6.2%, e 3: 80.6%, e 4: 13.2%) was not different from that in controls ( e 2: 4.1%, e 3: 87.6%, e 4: 8.3%). 2) In patients with CRF, total cholesterol, lowdensity lipoprotein (LDL) and high-density lipoprotein (HDL) levels were significantly lower and the triglyceride and lipoprotein (a) levels were significantly higher than those in controls. 3) In controls, E 4/3 group had significantly lower levels of HDL than E 3/3 and E 3/2 groups. In patients with CRF, E 4/3 group had significantly higher levels of total cholesterol and apo B lipoprotein than E3/2 group. In conclusion, although there was no significant difference in the apo E genotype frequencies between male patients with CRF and controls, apo E polymorphism may play an important role in the determination of individual differences in plasma lipids in male patients with CRF.
