World’s dialysis burden has grown 165% since 1990


 

AT KIDNEY WEEK 2013

ATLANTA – The global prevalence of maintenance dialysis for end-stage renal disease has increased 165% over the past 2 decades – a rate that has far outpaced that of population growth in most regions of the world, according to Dr. Bernadette A. Thomas.

The findings – the first to quantify the global burden of end-stage renal disease – underscore a need for improved detection of early chronic kidney disease and for treatment aimed at preventing end-stage renal disease (ESRD), because a continued rise in the prevalence of maintenance dialysis may not be sustainable, Dr. Thomas of the University of Washington, Seattle, said at Kidney Week 2013.

From 1990 to 2010, the global prevalence of maintenance dialysis in areas with universal dialysis access increased 134%, after adjustment for population growth and aging. The increase was 145% among women and 123% among men. Even in countries with a lack of universal access, the adjusted prevalence increased by 102% (116% for women and 90% for men).

The regions that did not experience an increase in dialysis prevalence included Oceania, South Asia, Central Sub-Saharan Africa, Eastern Europe, and tropical Latin America, Dr. Thomas said at the conference, which was sponsored by the American Society of Nephrology.

The findings are based on data extracted from the Global Burden of Disease database, the largest existing database for global causes of morbidity and mortality. Prevalence estimates were based on national and regional ESRD registries and a structured literature review. Data from 23 countries with universal dialysis access and from 138 countries with partial access were included; data from 26 countries that lack routine access were excluded.

"The statistics are appalling," American Society of Nephrology President Bruce A. Molitoris of Indiana University, Indianapolis, noted during a press briefing. Dr. Molitoris called for stepped-up efforts to educate the public about the importance of kidney health.

"We have targeted the patients in the past [via] patient education, and we have not presented, I think, a fair outlook to the public of the potential importance of kidney disease," he said.

Up to one-third of U.S. residents will, at some point in their lives, have severe kidney disease, Dr. Molitoris said, and 8% of African Americans and 3.6% of the total population will go on dialysis or need a transplant.

"And yet, people think they are immune to kidney disease," he cautioned. "The field is in need of innovation; the field is in need of individualization of care. And to do that, we have to have public awareness."

Kidney disease ranks near the bottom when it comes to research funding, and public awareness will go a long way toward changing that, he added.

Dr. Molitoris said he is optimistic that as the pharmaceutical industry continues taking an interest in kidney disease, and as public awareness increases, funding – and therefore innovation – will also increase. He said he envisions a time when the public will be as aware of their kidney function level as they are of their cholesterol level.

"With what is going on in science and technology and biology, it’s not a far leap for us to make major strides," he said.

The study by Dr. Thomas was supported by a private foundation. Dr. Thomas reported having no relevant financial disclosures. Dr. Molitoris reported consultancy, ownership interest, research funding, honoraria, and/or a scientific advisory or membership role for numerous companies. He also reported a patent/invention with FAST Diagnostics, Indiana University.
