Recognizing warning signs may prevent kidney injury

Washington, July 30 (ANI): A recent study has revealed that people with reduced kidney function and protein in the urine are more likely to have kidney injury.

The results have also suggested that improved recognition of these warning signs could help reduce preventable forms of acute kidney injury (AKI).

Acute kidney injury, which occurs when a person’s kidney function deteriorates over a short period of time, can have severe health consequences, including end stage kidney disease and even premature death.

Morgan Grams,Josef Coreshand colleagues at Johns Hopkins University studied risk factors for AKI in the general population.

Using information from a large population-based group of 11,200 individuals who were followed for an average of eight years, the researchers evaluated the potential links between acute kidney injury and markers of reduced kidney function (estimated glomerular filtration rate, or eGFR) and kidney damage (protein excreted in the urine, or albuminuria), as well as traditionally recognized risk factors, such as age, race, and sex.

The researchers discovered that patients with the highest levels of albuminuria had almost a 5-fold increased risk of developing AKI.

Similarly, the risk of developing acute kidney injury increased, as eGFR decreased. These associations persisted within subgroups of patients categorized by age, race, and sex.

“The results suggest that a person’s risk profile for acute kidney injury depends not only on eGFR, which is the basis of the current kidney disease staging system, but also on levels of albuminuria,” Grams said.

The findings were published in the journal of the American Society of Nephrology. (ANI)
