Abstract
Chronic kidney disease (CKD) is an important public health problem. Patients with end-stage renal disease have a significant renalase deficiency, which could be one of the mechanisms explaining high prevalence of hypertension in these patients. The aim of this study was to investigate the possible association of renalase gene (rs2296545) polymorphism with normotensive and hypertensive CKD in sampled Egyptian patients and to determine the effect of such polymorphism on epinephrine level. Renalase gene (rs2296545) polymorphism was genotyped in 178 patients with CKD (83 normotensive and 95 hypertensive nephrosclerosis) and 178 normal healthy adults using polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP). Epinephrine level was measured by HPLC method. We found an association of renalase (rs2296545) CC genotype and C allele with CKD. Also, the epinephrine level was significantly increased in normotensive and hypertensive nephrosclerosis patients as compared to controls. CKD patients with CC genotype showed significant high epinephrine level as compared to CG and GG genotypes.
