The Relationship Between Neutrophil-Lymphocyte Ratio And Early Renal Fibrosis And Renal Prognosis In Patients With Lupus Nephritis

Objective: To explore the relationship between neutrophil-lymphocyte ratio (NLR) and early renal fibrosis and renal prognosis in patients with lupus nephritis. Methods: A total of 186 patients with lupus nephritis admitted to our hospital were enrolled and grouped according to the standard of "NLR=3.175". There were 90 patients in the higher NLR group and 96 patients in the lower NLR group. The correlation and independent relationship between NLR/estimated glomerular filtration rate (eGFR) and pathological indicators were explored by comparing the differences of physiological indicators between the two groups. The correlation between NLR/eGFR and renal insufficiency and renal prognosis were explored. Results: The higher NLR group showed increased levels of hs-CRP, white blood cells, neutrophils, platelets, PLR values, eGFR, D-dimer, crescent compared with the lower NLR group, while lymphocyte count in the higher NLR group was lower than that in the lower NLR group. Platelets, neutrophils, white blood cells, serum anhydride, serum C4 and vascular cellulose had positive correlations with NLR. eGFR, age, systolic blood pressure, diastolic blood pressure, neutrophils, leukocytes, NLR, blood uric acid, triglycerides, crescent ratio, endothelial hyperplasia, spherical sclerosis ratio, intraglomerular leukocyte infiltration, platinum loop, micro-thrombus, nuclear fragmentation, interstitial inflammatory cell infiltration, renal tubular atrophy, interstitial fibrosis, and mesangial cell showed negative correlation with matrix hyperplasia, arteriolar wall thickening and pathological activity scores, but showed positive correlation with hemoglobin and low-density lipoprotein. Conclusion: NLR affects some important renal functions to a certain extent and is not the only risk factor for renal prognosis in patients with LN.
