A recent article in the European Medical Journal (EMJ) highlights the significant potential of the Neutrophil-to-Lymphocyte Ratio (NLR) as an inflammatory biomarker for the early identification and progression of diabetic nephropathy (DN). Diabetic nephropathy, a severe complication of diabetes, results from high blood sugar damaging the small blood vessels in the kidneys, ultimately leading to impaired waste filtering, chronic kidney disease (CKD), and often end-stage renal disease (ESRD). The comprehensive meta-analysis summarized by the EMJ, which included studies with over 14,000 participants, found that individuals with DN consistently exhibited significantly elevated NLR levels compared to diabetic patients without nephropathy. A higher NLR was also associated with the deterioration of kidney function in DN patients. While the association between NLR and mortality was not significant overall, subgroup analyses revealed stronger correlations in older patients and those with a higher BMI. The EMJ article cautiously suggests that NLR could be a future biomarker, emphasizing the need for larger, standardized research to confirm its clinical utility across the full spectrum of DN. This research is particularly relevant for an audience in India, where diabetes and its complications, including DN, pose a substantial public health challenge. Diabetic nephropathy is reported as the leading cause of chronic renal failure in India, accounting for 31% of cases. The overall prevalence of CKD in Indian adults is estimated at 17.2%. Indian studies have independently corroborated the utility of NLR, noting its proportional increase with albumin excretion and its potential as an early indicator and prognostic risk marker for DN. Researchers in India emphasize that NLR is a simple, inexpensive, and routinely available test, making it an accessible screening tool for early detection in a resource-constrained environment. Early identification and intervention are crucial to slow or halt the progression of DN, thereby improving patient outcomes and reducing the burden of kidney disease.
