A systematic review and meta-analysis featured in the European Medical Journal (EMJ) has established a significant link between an elevated Neutrophil-to-Lymphocyte Ratio (NLR) and both the risk and progression of Diabetic Nephropathy (DN). The study suggests that NLR could serve as a valuable inflammatory biomarker for identifying individuals at increased risk of developing DN and monitoring its advancement. Diabetic Nephropathy is a severe complication of diabetes and ranks among the primary causes of chronic kidney disease (CKD) and end-stage renal failure globally. The challenge of early identification in at-risk patients has spurred interest in readily available and economical biomarkers. NLR, which is calculated from routine blood counts, acts as an indicator of systemic inflammation and has garnered attention across various chronic diseases. The comprehensive analysis reviewed 39 cohort and case-control studies, encompassing 14,300 participants, to assess the correlation between NLR and DN occurrence, disease progression, and mortality. The findings consistently revealed a robust association between elevated NLR and the presence of DN; patients with DN exhibited notably higher NLR levels compared to diabetic individuals without nephropathy, indicating over a twofold increased odds of DN occurrence. Furthermore, among patients already diagnosed with DN, higher NLR values were also linked to a deterioration in kidney function, suggesting its prognostic value for disease progression. While a trend towards increased mortality risk was observed with higher NLR, it did not achieve statistical significance in the pooled results. Subgroup analyses, however, hinted at stronger associations in older patients (aged 60+) and those with a BMI of 25 kg/m² or higher. Credible sources, including studies indexed on NIH and published in other medical journals, corroborate these findings, affirming NLR as an early indicator and prognostic marker for DN. The European Medical Journal is a peer-reviewed, open-access publication established in 2012, bolstering the credibility of this research. The implications of this research are particularly relevant for countries like India, where diabetic nephropathy is a significant public health burden, affecting a substantial portion of the diabetic population and contributing significantly to chronic kidney disease prevalence. Although promising, the EMJ article also prudently notes the potential for bias and heterogeneity in the included studies, advocating for further large-scale, standardized research before widespread clinical implementation.
