In a significant advancement for diabetes care, researchers from IIT Bombay, collaborating with Osmania Medical College, have discovered novel blood biomarkers capable of detecting early signs of diabetic kidney disease (DKD). This breakthrough offers hope for millions of diabetes patients worldwide by potentially enabling earlier diagnosis and personalized treatment strategies, drastically reducing the risk of severe complications.
An Urgent Need for Early Diagnosis
Diabetic kidney disease is one of the most serious complications associated with Type 2 diabetes. It affects approximately one in three diabetic patients worldwide and is a primary cause of kidney failure, also impacting cardiovascular health and vision. Alarmingly, many patients are diagnosed only when the disease has progressed significantly, limiting effective treatment options.
The late diagnosis often results in irreversible kidney damage and heightened risk of heart disease and blindness. Early detection is critical to managing DKD progression and improving patient outcomes, but current clinical tests such as urinary albumin levels and serum creatinine often fail to identify subtle, early-stage changes.

The Scientific Breakthrough
The cutting-edge study, led by Prof. Pramod Wangikar of IIT Bombay and Dr. Rakesh Kumar Sahay and Dr. Manisha Sahay of Osmania Medical College, utilized metabolomics—a sophisticated approach that studies small molecules (metabolites) in biological samples. Through this technique, the researchers analyzed the blood metabolite profiles of diabetic patients at varying stages and compared them to healthy individuals.
Using advanced equipment like liquid chromatography-mass spectrometry (LC-MS) and gas chromatography-mass spectrometry (GC-MS), the team assessed nearly 300 metabolites from whole blood samples of 52 participants over a year. This approach enabled the detection of intricate metabolic changes signaling early kidney dysfunction.
Their findings revealed 26 metabolites significantly altered in diabetic subjects. More importantly, seven metabolites including myo-inositol, arabitol, ribothymidine, and the uremic toxin 2PY progressively increased with worsening kidney function, suggesting their potential as early warning biomarkers.
Dr. Manisha Sahay highlighted the clinical importance, saying, “These biomarkers could enable doctors to identify patients at risk much earlier than currently possible, opening doors for timely intervention tailored to individual needs.”

Advantages Over Traditional Testing
Unlike conventional markers, which detect kidney damage only at later stages, these novel biomarkers can flag risk long before symptoms or abnormal lab values emerge. Also, using whole blood samples—simpler to collect than plasma—could facilitate easier, less invasive and more affordable testing, potentially even from dried blood spots via finger pricks.
This research represents a major leap in personalized medicine for diabetes care, allowing interventions to be specifically tailored based on metabolic profiles rather than a one-size-fits-all approach.

Potential Impact on Public Health
With India recognized as the diabetes capital of the world, home to over 101 million adults with diabetes and many more prediabetic, the implications are profound. Early diagnosis through blood biomarkers could lead to improved clinical decision-making, slowing or preventing kidney disease progression. This would reduce the need for dialysis or transplantation, ultimately lowering healthcare costs and improving quality of life for millions.
The Innovation also holds promise globally in regions facing rising diabetes incidence and related complications.

Future Directions
While the discovery is promising, the researchers emphasize the need for large-scale clinical trials to validate these biomarkers before they can be routinely used in clinics. Ongoing collaborations with hospitals and biotech companies aim to develop affordable, easy-to-use diagnostic kits based on these findings.
The team is optimistic that integrating biomarker-based screening into routine diabetes management could become standard practice in the near future.
