New Data Shows Kidney Disease Rising Due to Diabetes

New data confirms the rate of chronic kidney disease is increasing along with the rising rates of diabetes. Up to 40% of people with diabetes will experience kidney problems in their lifetime.

In late September, the U.S. Renal Data System published its 2009 Annual Data report, which shows the incidence of chronic kidney disease in the U.S. Medicare population is now 9.8%, up from 8.7% reported in last year's data analysis.

The American Diabetes Association recommends people with diabetes check their kidneys with an annual microalbumin test. However, fewer than 40% of Texas Medicare beneficiaries with diabetes received this screening in 2007, according to claims data from the Centers for Medicare & Medicaid Services.

"I regularly see patients who discover they have kidney disease when they come to the hospital for emergency treatment because their kidneys have failed," Dr. Collazo continues. "This is too late. People with diabetes must check their kidney health every year."

"It's optimal to treat kidney disease before the damage is apparent to the patient," says Dr. Collazo. "In the earliest stages, it's unlikely the patient will experience obvious symptoms that would prompt a doctor's visit."

The urine microalbumin test looks for traces of albumin, a protein, in a patient's urine. Damage impairs the kidneys' ability to filter the blood for proteins, which then "spill" into a patient's urine. This is an early marker of kidney disease.

"Getting a microalbumin test is very easy. It's just a urine sample. No needles and no pain," says Dr. Collazo. "If we find kidney disease at the early stages, we can treat it and most likely avoid dialysis. Not everyone with kidney damage progresses to kidney failure, but first you have to get tested regularly and then get timely treatment to prevent that outcome."

Up to 40% of people with diabetes will experience kidney problems in their lifetime. Minorities with diabetes are also disproportionately affected: African-Americans are four times more likely than Caucasians to experience kidney failure, and Mexican-Americans with diabetes are twice as likely as non-Hispanic whites to have diabetes.

Accounting for 44% of new cases, diabetes is the leading cause of kidney disease, the U.S. Renal Data System reported in 2007.
