ABSTRACT
PURPOSE:
Klotho mutant mice showed abnormal calcium and vitamin D metabolism, hyperphosphatemia and vascular calcification. We observed the frequencies of klotho gene polymorphism and investigated their relation with some clinical parameters including serum osteoprotegerin (OPG) levels in maintenance hemodialysis (HD) patients.METHODS:
Total 88 patients (mean age 58+/-13 years, malefemale=4741) on maintenance HD were enrolled. The genotypings for G-395A in promoter and C1818T in exon 4 of klotho gene were performed with real-time polymerase chain reaction. We measured blood pressure, body mass index (BMI), and serum calcium, phosphorus, parathyroid hormone (PTH), alkaline phosphatase, hs-CRP, lipid profiles and OPG.RESULTS:
In G-395A in promoter, the distribution of genotypes was GG 66% (n=58), GA 23% (n=20) and AA 11% (n=10), respectively and the allele frequencies were 0.773 for G allele and 0.227 for A allele. In C1818T in exon 4, the distribution of genotypes was CC 63% (n=55), CT 30% (n=26), and TT 7% (n=7), and the frequencies were 0.773 for C allele and 0.227 for T allele. G-395A shows correlations with BMI and HDL-cholesterol (p<0.005). G-395A and C1818T in klotho gene show no statistical correlation with other clinical parameters of vascular calcification including OPG.CONCLUSION:
Klotho G-395A and C1818T polymorphisms are not correlated with OPG in maintenance HD patients. Further research needs for the other klotho polymorphisms on chronic kidney disease and end-stage renal disease.
