A study was conducted by the School of Medicine in Baltimore, Maryland to determine the proportion of end-stage renal failure in people with diabetes.
The researchers studied 716 newly-treated patients, aged 20-64, with kidney failure. They also selected 361 age-matched controls.
It was found that the risk of end-stage renal failure was only slightly increased for diabetes lasting less than 15 years, but the ratio increased more than 20-fold for diabetes lasting more than 15 years.
The people with diabetes (both type I and II) had a 42 percent chance of developing kidney failure. Type I diabetes, however, played a greater role in kidney failure among the Caucasian subjects, and type 2 played a greater role among the African-Americans in the study.
The researchers concluded that the prevention of end-stage renal failure in both types of diabetes requires increased attention from doctors to laboratory and clinical research reports.
