FRIDAY, Dec. 7 (HealthDay News) -- The incidence of the most
severe form of acute kidney injury increased dramatically in the
United States over the past decade, and deaths associated with the
condition doubled over that time, a new study says.
Acute kidney injury refers to the abrupt or rapid decline in
kidney function that can occur after serious infections, major
surgery or taking certain medications. Acute kidney injury is one
of the most common and serious complications of hospitalized
patients. The most severe form of acute kidney injury requires
Researchers analyzed national data for the years 2000 to 2009
and found that the incidence of acute kidney injury requiring
dialysis rose about 10 percent on average a year. Older people, men
and blacks were most likely to develop dialysis-requiring acute
The number of deaths associated with dialysis-requiring acute
kidney injury increased from 18,000 in 2000 to nearly 39,000 in
2009, according to the study released Dec. 6 in advance of
publication in an upcoming issue of the
Journal of the American Society of Nephrology.
The incidence of dialysis-requiring acute kidney injury is now
greater than the incidence of kidney failure requiring dialysis or
transplant, the researchers said.
"Most of the discussion regarding the 'epidemic of kidney
disease' in the past decade or more has been focused on chronic
kidney disease and end-stage [kidney] disease. We want to point out
that acute kidney injury is equally important," study author Dr.
Chi-yuan Hsu, of the University of California, San Francisco, said
in a news release from the American Society of Nephrology.
Because the number of acute kidney injury cases that don't
require dialysis is about 10 times higher than the number of
dialysis-requiring acute kidney injury cases, and because even
small changes in kidney function are associated with increased
illness and death, the data in the study likely represent only the
"tip of the iceberg" in terms of the public health burden of acute
kidney injury, the researchers pointed out in the news release.
Further research is needed to pinpoint the causes behind the
sharp rise in the incidence of dialysis-requiring acute kidney
injury, they added.
