Abstract

Background: Recent studies have shown that neutrophil lymphocyte ratio (NLR) is a strong indicator in determining inflammation in cardiac and non-cardiac diseases. We aimed to evaluate the relationship between proteinuria and NLR in chronic kidney disease (CKD) patients without diabetes mellitus (DM).

Methods: Between 2011 and 2012 files of a total of 1000 CKD patients attending outpatient clinic were retrospectively scanned. Patients with DM, chronic disease, malignancy or stage 5 CKD were excluded. After these patients were excluded, a total of 69 patients with stage 3 and 4 CKD were evaluated.

Results: The study comprised 27 patients with CKD without proteinuria (Group 1), 42 patients with CKD and proteinuria (Group 2) and 30 healthy volunteers (Group 3). NLR was highest in Group 2 and this was statistically significant compared with the control group (p = 0.012). The platelet lymphocyte ratio (PLR) in Group 2 was higher than the control group at a significant level (p = 0.004). There was a moderate positive correlation found between proteinuria and NLR (p = 0.013, r = 0.3). There was a positive correlation found between proteinuria and PLR (p = 0.002, r = 0.306).

Conclusion: In conclusion, NLR, a parameter easily found in routine blood counts of CKD patients, is a marker with prognostic value for the presence and degree of proteinuria.
