(Press-News.org) New estimates published in The Lancet indicate that at best only half of people worldwide needing kidney dialysis or transplantation to treat kidney failure in 2010 received it. This suggests that at least 2.3 million people may have died prematurely from kidney failure because they could not access this life-saving treatment.
The research shows that most of these preventable deaths occurred in China, India, Indonesia, Pakistan, and Nigeria, where less than a quarter of eligible patients receive treatment for kidney failure.
"The high cost of current dialysis techniques (US$ 20 000-100 000 per person each year) are unaffordable to most people who need it," [1] says lead author Professor Vlado Perkovic of The George Institute for Global Health and The University of Sydney, Australia.
"With the number of people receiving dialysis or kidney transplantation set to more than double to over 5 million by 2030 there is a dire need for low-cost dialysis techniques, as well as population-wide prevention programmes to tackle the key risk factors for end-stage kidney disease including diabetes, high blood pressure, and obesity." [1]
Perkovic and colleagues systematically reviewed observational studies, renal registries, and contacted national experts to collect data on the actual numbers of patients receiving renal replacement therapy (RRT; dialysis and kidney transplantation) in 123 countries, representing 93% of the world population. They used mathematical modelling to develop both upper and lower estimates of the likely need for RRT in each country, and projected needs to 2030.
The findings show that 2.62 million people were actually treated with RRT in 2010, with 78% of them given dialysis (see table 2 page 3). Most (92.8%) of those treated in 2010 lived in high- or high-middle income countries, and just 7.2% in low- and low-middle income countries.
However, the authors calculated that worldwide the number of patients needing RRT in 2010 were 4.9 million in a conservative model (in which RTT was only partly implemented) and 9.7 million if RRT access were high in all countries. "These scenarios suggest that between 2.3 million and 7.1 million individuals who could have been kept alive with RRT in 2010 died prematurely because treatment was unavailable," [1] explains Perkovic.
The authors also forecast that the number of people receiving RRT will more than double to 5.4 million by 2030, mostly in developing regions such as Asia (from 0.968 million in 2010 to 2.162 million by 2030) and Africa (from 0.083 million to 0.236 million; see figure 5 page 6).
According to Professor Perkovic, "Quantifying the burden of end-stage kidney disease is vital because without good numbers there can be no targets for improvement or evidence for industry to invest in developing new low-cost technologies for RRT. The large number of deaths occurring because of poor access to treatment sets a demanding task for the nephrology community and the health-care and research communities in general." [1]
Writing in a linked Comment, Josef Coresh from John Hopkins University, Baltimore, USA, and Tazeen Jafar from Duke-NUS Graduate Medical School in Singapore say, "Reduction in worldwide inequity in access to RRT needs attention to chronic kidney disease from international donors and developmental agencies. Engagement of powerful new partners, such as the Bill & Melinda Gates Foundation and the UK Department for International Development, might be needed to make substantial progress in low-income and middle income countries. The time has come to include treatment of kidney failure, and its prevention by detection and management of chronic kidney disease, in the global health agenda."
As a result of this research, three leading players in global kidney health have joined together to create a world-wide competition, with a prize of $100,000, to design the world's first truly affordable dialysis machine. The prize is sponsored by The George Institute, the International Society of Nephrology and the Asian Pacific Society of Nephrology with the support of the Farrell Family Foundation.
According to Perkovic, "Dialysis machines purify the blood, replacing an essential function of the kidneys. If we can develop an affordable dialysis machine with low operating costs, that runs on solar power and uses local water sources, many more people will have access to the treatment and millions of lives could be saved."

SAN DIEGO -- Healthy young adults who don't consume caffeine regularly experienced greater rise in resting blood pressure after consumption of a commercially available energy drink -- compared to a placebo drink -- thus raising the concern that energy drinks may increase the risk of cardiac events, Mayo Clinic researchers found.
Results of the study will be presented Saturday, March 14, at the American College of Cardiology's 64th Annual Scientific Session in San Diego.
In this study, researchers alternately gave a can of a commercially available energy drink or a placebo ...

A study led by Massachusetts General Hospital (MGH) investigators suggests that bariatric surgery can significantly reduce the risk of asthma attacks - also called exacerbations - in obese patients with asthma. Their report, published online in the Journal of Allergy and Clinical Immunology, is the first to find that significant weight reduction can reduce serious asthma-associated events.
"We found that, in obese patients with asthma, the risk of emergency department visits and hospitalizations for asthma exacerbations decreased by half in the two years after bariatric ...
Media and popular culture might portray religion and science as being at odds, but new research from Rice University suggests just the opposite.
Findings from the recently completed study "Religious Understandings of Science (RUS)" reveal that despite many misconceptions regarding the intersection of science and religion, nearly 70 percent of evangelical Christians do not view the two as being in conflict with each other.
The research was presented by Rice sociologist Elaine Howard Ecklund today in Washington, D.C., during the American Association for the Advancement ...
Case Western Reserve researchers are part of an international team that has discovered that a common herpes drug reduces HIV-1 levels -- even when patients do not have herpes.
Published online in Clinical Infectious Diseases, the finding rebuts earlier scientific assumptions that Valacyclovir (brand name, Valtrex) required the presence of the other infection to benefit patients with HIV-1.
The result not only means that Valacyclovir can be used effectively with a broader range of HIV-1 patients, but also suggests promising new avenues for the development of HIV-fighting ...
Washington, D.C.-Two new papers from members of the MESSENGER Science Team provide global-scale maps of Mercury's surface chemistry that reveal previously unrecognized geochemical terranes -- large regions that have compositions distinct from their surroundings. The presence of these large terranes has important implications for the history of the planet.
The MESSENGER mission was designed to answer several key scientific questions, including the nature of Mercury's geological history. Remote sensing of the surface's chemical composition has a strong bearing on this and ...
Among the facts so widely assumed that they are rarely, if ever studied, is the notion that wider hips make women less efficient when they walk and run.
For decades, this assumed relationship has been used to explain why women don't have wider hips, which would make childbirth easier and less dangerous. The argument, known as the "obstetrical dilemma," suggests that for millions of years female humans and their bipedal ancestors have faced an evolutionary trade-off in which selection for wider hips for childbirth has been countered by selection for narrower hips for ...
WASHINGTON - A legal scholar and tobacco control expert says he has developed a research-based roadmap that allows for the immediate regulation of e-cigarettes.
Writing in the March issue of Food and Drug Law Journal, Eric N. Lindblom, JD, senior scholar at the O'Neill Institute for National and Global Health Law, says his proposal would minimize the threats e-cigarettes pose to public health while still enabling them potentially help reduce smoking.
"This approach could help to heal the current split in the public health community over e-cigarettes by addressing ...
New research led by University of York scientists highlights how poor connectivity of protected area (PA) networks in Southeast Asia may prevent lowland species from responding to climate change.
Tropical species are shifting to higher elevations in response to rising temperatures, but there has been only limited research into the effectiveness of current protected area networks in facilitating such movements in the face of climate change.
However, the new study, published in the journal Biological Conservation, focuses on the connectivity of the protected area network ...
