近年美国肾脏疾病的治疗方法不断改进

近日，来自美国肾脏病数据库系统的研究人员通过研究表示，尽管近年来美国肾脏疾病的发生率在逐年升高，但个体肾衰竭及相关死亡率却在不断下降。数据库中数据显示，如今在美国有14%的成年个体患有慢性肾脏疾病，其会进展成为肾衰竭。而慢性肾脏疾病的风险因子包括糖尿病、高血压、肥胖以及急性肾脏损伤等。

由于老龄化及过重人群的增加，终末期肾病的患者比率也在一直上升，据2012年的研究数据显示，在美国大约有637000名肾衰竭病人正经历着透析以及肾脏移植，这其中包括115000名被诊断为肾衰竭的个体。

研究者表示，然而这些患者或许表现比较良好，而且生存时间更久，从2010至2012年以来潜在的致死性肾衰竭的新发病例呈直线下降，Rajiv Saran教授说道，目前我们宣布抵御肾衰竭的胜利还为时过早，但是我们的分析数据却为揭示美国肾衰竭患者的现状提供了一定的参考数据。

后期研究者们将根据此前的研究数据来观察是否肾脏疾病的发生率会持续下降，研究者们认为，一种改善肾脏健康的综合性方法或许应该包括疾病的预防以及慢性肾脏疾病相关知识的知晓；有时候患病信号不足以引起个体主义，但是简单的测试或许就可以帮助进行个体肾脏疾病的早期诊断。

Researchers at the United States Renal Data System (USRDS) say that about 14 percent of U.S. adults have chronic kidney disease, which can progress to kidney failure. Risk factors for chronic kidney disease include diabetes, high blood pressure, obesity, acute kidney injury, a family history of kidney disease, being 50 and older, and being a member of a minority.

Because of an aging and overweight population, the rate of end-stage kidney disease is on the rise, according to USRDS.

According to 2012 data, across the United States almost 637,000 kidney failure patients are undergoing dialysis or have received a kidney transplant, including about 115,000 people diagnosed with kidney failure.

However, patients may be faring better and living longer, the report's authors said. The growth rate for new cases of potentially fatal kidney failure fell for three years in a row, from 2010 to 2012, according to the 2014 annual report from the USRDS, which is based at the University of Michigan.

"It is too soon to declare victory on the war against the rising tide of kidney failure, but our analysis provides some good news about kidney disease in the U.S.," Dr. Rajiv Saran, director of the USRDS coordinating center, said in a university news release......
