Kidney Disease Incidence Increasing

More acute renal failure associated with diabetes and hypertension

MONDAY, March 31 (HealthDay News) -- The number of patients discharged from the hospital with a diagnosis of kidney disease has been increasing since the 1990s, and there has been a shift from chronic kidney failure to acute renal failure, associated with a concomitant diagnosis of diabetes mellitus or hypertension, according to a report published in the March 28 issue of the U.S. Centers for Disease Control and Prevention's Morbidity and Mortality Weekly Report.

Nicole T. Flowers, M.D., and J.B. Croft, Ph.D., of the CDC's National Center for Chronic Disease Prevention and Health Promotion in Atlanta, report that between 1980 and 2005, there were approximately 10 million hospitalizations with a recorded diagnosis of kidney disease, and that the incidence rose from 416,000 in 1980 to almost 1.65 million in 2005.

Acute renal failure accounted for 7.3 percent of kidney disease hospitalizations in 1980, versus 60 percent by 2005, the researchers report. The proportion of patients with an additional diagnosis of diabetes mellitus rose from 23.4 percent in 1980, peaked at 39 percent in 1996 and was 27 percent in 2005. Hypertension diagnoses rose from 19.6 percent of cases in 1980 to 41.1 percent in 2005, the investigators found.

"These findings indicate a need for additional research to determine the cause of the increase in acute renal failure discharge diagnoses and to quantify the progression from acute renal failure to chronic kidney disease and end-stage renal disease," the authors write.
