Abstract
Background/Aims: Some studies had suggested that neutrophil lymphocyte ratio (NLR) levels grow 
with the increase of nerve conduction velocity (NCV). Recently, several studies found that vitamin (D) 
deficiency can cause the risk of diabetes mellitus (DM) and its complication including neuropathy.
The aim of our study is to evaluate the association between NLR, vitamin (D) deficiency and 
development of peripheral neuropathy in type 2 diabetic (T2DM) patients. Methods: In cross sectional
study we selected a total of 60 T2DM patients. All patients underwent nerve conduction study (NCS). 
Then we divided them according to the results into two groups, 45 patients with DPN and 15 patients 
without DPN as a control group. DPN group was subdivided according to NCS results into three 
groups, 11 patients with mononeuropathy, 4 patients with mononeuropathy multiplex and 30 patients 
with polyneuropathy. We evaluated the effect of DPN in these patients as regarded NCS results on 
HbA1c levels, NLR and vitamin (D) levels. Results: There were very highly statistically significant 
differences between DPN group and non-DPN group as regard HbA1c and [25(OH) D] levels, (P < 
0.001*** for all). There was no statistically significant difference between them as regarded NLR, (P 
= 0.501). Multivariate logistic regression analysis showed that, [25(OH) D] levels and duration of DM
were independent risk factors for DPN, (P = 0.041*, OR = 0.88, 95% CI = 0.78-0.10), (P = 0.016*, 
OR = 1.54, 95% CI = 1.09-2.18) respectively. Conclusions: Vitamin (D) deficiency and HbA1c levels 
may be independent risk factors for development of DPN in T2DM in Minia. It is important to supply 
vitamin (D) appropriately and control of diabetes for preventing the generation of DPN in T2DM. 
NLR can't be a predictor for DPN.
