Evaluation of whole blood, mean platelet volume (MPV) and neutrophil-lymphocyte ratios (NLR) in people with B12 vitamin deficiency

Abstract

Introduction: It was aimed to investigate the effects of vitamin B12 deficiency on blood tests, mean platelet volume (MPV), and neutrophil-lymphocyte ratio (NLR), which is one of the inflammation markers.Methods: Our study is a case-control study of 375 patients. 170 patients with low B12 ( lt;130 pg/dL) were accepted as the experimental group, and 205 individuals with normal B12 levels were accepted as the control group. Between these two groups, white blood cells (WBC), platelet count (Plt), hemoglobin (Hgb), mean erythrocyte volume (Mean Corpuscular Volume-MCV), mean platelet volume (Mean Platelet Volume-MPV), neutrophil, lymphocyte counts, and neutrophil -lymphocyte ratios (NLR) were examined.Results: The mean age was 48.45 ±17.497 years in the B12 deficient group and 51.93 ±16.175 years in the control group. The mean of vitamin B12 in the deficient group was 101.41 ± 20.50 pg/mL (min-max 37-130), while it was 257.24 ± 88.13 pg/mL (131–498) in the control group. It was observed that there was no statistically significant difference between WBC, Hgb, Plt, neutrophil, lymphocyte, MVC, MPV and NLR values.Conclusion: In our study, we could not find a significant relationship between B12 deficiency and blood tests. In previous studies, there has been information that MPV values are affected by B12 deficiency. In our study, we found that there was no significant relationship between B12 deficiency and MPV or NLR (p gt; 0.05). There is a need for new studies on how B12 deficiency will change as the degree and duration of B12 deficiency increases, especially its effect on atherogenic events.
