Objective: To study the association between a high preoperative neutrophil lymphocyte ratio (NLR) and red cell distribution width (RDW) with arteriovenous fistula (AVF) failure, as well as to determine the cut-off values in a South Asian population.

Materials and Methods: A total of 150 consecutive patients with a failed fistula who presented in the Department of Vascular Surgery between January 2014 and January 2016. Patients fulfilling the inclusion criteria were selected as defined as Case. They were compared with 150 patients who had matured fistulae (Control).

Results: A significant difference was found between the Case and Control groups in mean preoperative NLR (3.3±0.5 versus 2.2±0.9, P value=0.011) and RDW (15.9±2.9 versus 13.6±1.1%, P value of 0.02), respectively. Multivariate analysis revealed that NLR (Odds Ratios (OR) 1.39; 95% Confidence Intervals (CI) 1.02 to 2.08; P<0.001) and RDW (OR 1.39; 95%CI 1.11 to 1.69; P<0.001) were strong independent predictors of AVF failure. A receiver operating characteristic curve analysis showed a cut-off value of 2.65 (specificity 80%, sensitivity 98%) and 15.1 (specificity 79%, sensitivity 98%) for NLR and RDW, respectively.

Conclusion: Increased preoperative NLR and RDW were associated with a high rate of AVF failure in a South Asian population.
