Cinacalcet,小说calcimimetic化合物,是有效减少甲状旁腺激素(素水平在大约70%的患者继发性甲状旁腺功能亢进。然而,个人间的差异实现治疗目标所需的剂量已经在临床研究指出。我们的调查研究的基因多态性calcium-sensing受体(CaSR)基因cinacalcet不同反应的一个可能的原因。我们报告数据七个终末期肾功能衰竭患者接受常规血液透析和cinacalcet参与临床试验。所有患者继发性甲状旁腺功能亢进与基线完整的甲状旁腺素(iPTH)水平大于600 pg / ml。男4女3名患者平均+ / -标准差60岁+ / -12年。从外周淋巴细胞DNA提取。CaSR基因外显子7的面积扩大了聚合酶链反应、测序。意思是+ / -标准差基线iPTH 1086 + / -189 pg / ml。五个病人没有Arg990Gly演示了一个29.7 + / - -4.0%(+ /钙减少iPTH从个人基线。 One patient was found to be homozygous for the Arg990Gly polymorphism and another was heterozygous for both arginine and glycine alleles. The homozygous patient showed a significantly higher sensitivity to cinacalcet compared to the other patients (P=0.003) with a 76.3+/-7.7% reduction in iPTH from baseline. No polymorphisms were noted in codons 986 or 1011. This preliminary study points to the possibility that patients homozygous for glycine at the 990 position in exon 7 of the CaSR may be more sensitive to the calcimimetic drug cinacalcet compared to those who are homozygous for arginine at that location.
