Abstract
BACKGROUND
Dyslipidemia is an important complication in renal transplant patients. Cholesteryl ester transfer protein (CETP) mediates the exchange of cholesteryl ester between high density lipoproteins and low density lipoproteins. The aim of this study was to investigate CETP Taq1B gene polymorphism and lipid abnormalities in renal transplant patients.
METHODS
We studied 29 renal transplant patients and 29 healthy controls. CETP Taq1B polymorphism was determined by polymerase chain reaction and restriction fragment length polymorphism techniques. Serum lipid levels were measured enzymatically. Statistical analyses was performed by SPSS for Windows version 7.5.
RESULTS
The frequencies of CETP Taq1B B1B1, B1B2, and B2B2 genotypes in patients were 44.8%, 34.5%, and 20.7%; and in control subjects, 37.9%, 37.9%, and 24.2%, respectively. The patients with B1B1 genotype displayed higher levels of total cholesterol (TC), triglycerides, low density lipoprotein-cholesterol (LDL-C), very low density lipoprotein-cholesterol (VLDL-C), and diastolic blood pressure (DBP). (P<.05). Also, patients showing a B1 allele had higher levels of TC, LDL-C, VLDL-C, and DBP compared to healthy controls (P<.05).
CONCLUSION
We observed that CETP Taq1B B1 allele and B1B1 genotype have effects on the serum lipid profile among renal transplant patients.
