Abstract：Objective To investigate characteristics of dislipidemia and the effect of gene polymorphism of low density lipoprotein receptor related protein (LRP) tetranucleotide on hemodialysis patients. Methods Serum total cholesterol (TC),triglyceride (TG),low density lipoprotein cholesterol (LDLC),high density lipoprotein cholesterol (HDLC),apolipoproteins (Apo A1,B,E) and lipoprotein(a) [Lp(a)] were measured;polymerase chain reaction-restriction fragment length polymophism (PCR-RFLP) was used to detect LRP gene polymorphism in hemodialysis patients. Results Serum levels of TG and ApoB were significantly higher in the hemodialysis patients than those in contrals,and the levels of TC,LDLC,HDLC were lower compare to those in contrals. Patients with cardiovascular disease had higher TG level comparing to the patients without cardiovascular disease. The data of LRP polymorphism detected by PCR-RFLP showed that the allele frequency and the distribution of the LRP genotype of tetranucleotide reapeat sequence did not differ significantly between controls and hemodialysis patients. There was no statistic difference of serum lipid levels among hemodialysis patients with different genotype of LRP tetranucleotide.Conclusions Hemodialysis patients can develop hypertrglyeridemia and hypocholesteroldemia. TG level might be related to the development of cardiovascular disease in hemodialysis patients. The gene polymorphisms of LRP tetranucleotide dose not affect the lipid levels significantly in hemodialysis patients.
