In a significant medical breakthrough, UT Health San Antonio researchers have pinpointed a molecule, adenine, in the urine that can foretell kidney failure in diabetes patients years before its onset. As reported by FOX San Antonio, this discovery holds the potential to revolutionize the monitoring and treatment of those at risk.
The research, which spanned approximately four to five years, found that elevated levels of urine adenine are connected to kidney damage. This correlation could predict kidney failure in diabetic patients five to ten years prior to its occurrence. According to Dr. Kumar Sharma, Chief of nephrology at UT Health San Antonio, "If they are at high risk of kidney failure even if they don’t have protein in their urine and those patients could be treated either with more intensive dietary modifications, or a new medication that will control their diabetes and specifically lower adenine in the urine and in the kidney and protect their kidneys in the long run." The test, though currently experimental, is expected to be widely available in due course.
A deeper dive by UT Health San Antonio News into this revolutionary research reveals it carries significance due to the fact that many diabetes patients who eventually suffer kidney failure do not exhibit elevated protein levels in their urine. The study examines over 1,200 diabetic patients and utilizes spatial metabolomics on kidney biopsies, a technique that, though complex, enables precise analysis of metabolites like adenine in kidney tissues.
With implications clear across a range of diverse study populations, including African American, Hispanic, Caucasian, and Asian cohorts, the consistency of these findings cannot be overstated. Dr. Sharma told UT Health San Antonio News, "We are truly grateful for all the participants in this global study, and I would like to thank all of the investigators and research teams who were part of this collaborative effort." Moreover, a promising oral therapeutic drug that blocks endogenous adenine production showed positive results in protecting against major aspects of diabetic kidney disease in mice, providing hope for future treatments free from dialysis dependency.
UT Health San Antonio is at the forefront of these groundbreaking investigations, aiming to extend the life of kidneys for diabetic patients before they need dialysis, a life-altering procedure associated with a high mortality rate, especially in those with concurrent diabetes. This research has garnered the support and funding from the National Institutes of Health and the National Institute of Diabetes and Digestive and Kidney Diseases, demonstrating the high stakes and potential impact of these findings on diabetic kidney disease management.
