Baltimore - The presence of protein in urine can indicate that someone was injured on the kidney.Patients who have high levels of urine, or albuminuria, have a fivefold risk of suffering from acute kidney injury, reports a number of researchers in the Journal of the American Society of Nephrology.
Finding protein in the urine through an easy and inexpensive test may be used as a way to see the damage the kidneys and improve inspection methods applied at this time, called the estimated glomerular filtration rate, said a team from the University of Johns Hopkins University in Baltimore.
Acute kidney injuries, which often happens when people are in hospital, recorded at 1.6 percent of all hospital patients and occurs when the kidneys suddenly lose the ability to filter waste products from blood.
Acute renal injuries could be cured if the patient is healthy enough, but often causes chronic kidney disease and kidney failure requiring dialysis or kidney transplantation.
"Potential to be cured, but not always. And the reason why we are very concerned with acute kidney injury is that it can cause bad things in the future, increasing the risk of death, and the risk of becoming chronic kidney disease," said Dr Morgan Grams, who worked on the study.
Grams and colleagues studied 11 200 patients, by examining their medical records. They have been tested for albuminuria as part of their treatment.
The researchers found that even low levels of albuminuria may indicate that patients experiencing acute kidney injury.
Kidney injuries may occur when patients receive the drug or a substance through an IV to make their organs can be seen during the examination by computer tomography or CAT scan or procedure in the coronary arteries.
"You have to undergo a CAT scan, but you can try to minimize the amount of material supplied or to provide better ingredients," Gram said as reported by Reuters.
According to the American Society of Nephrology, nearly 30 million Americans, or 10 percent of the country's population, suffer from chronic kidney disease. More than 100,000 Americans diagnosed with kidney failure each year, with diabetes as the main cause.
The doctors have a clear way to measure risk factors for chronic kidney disease. They test the serum levels of creatinine in the blood. They adjust the measurements to demographic risk factors such as age, gender and race. "This is to measure the overall population of people who are at risk of suffering from acute kidney injury," said Grams.
It is estimated that there are genetic links. Scientists at Decode Genetics in Iceland found a link between single-letter variations in the genetic code with the concentration of serum creatinine, a protein that indicates chronic kidney disease.
According to them in the journal PLoS Genetics of the Public Library of Science, the discovery could lead to better ways to prevent kidney disease.
