Neutrophil-to-Lymphocyte Ratio is a strong predictor of atherosclerotic carotid plaques in older adults

The Neutrophil-to-Lymphocyte Ratio (NLR), an index of systemic inflammation, has been reported to be associated with subclinical atherosclerosis, but its predictive role of the presence of carotid atherosclerotic plaques remains undefined. This study aims to assess this association which gives addit...

Description
Summary:The Neutrophil-to-Lymphocyte Ratio (NLR), an index of systemic inflammation, has been reported to be associated with subclinical atherosclerosis, but its predictive role of the presence of carotid atherosclerotic plaques remains undefined. This study aims to assess this association which gives additional value to this biomarker, with respect to the main risk factors, in the prediction of carotid atherosclerosis in older adults. We recruited 324 patients, aged ≥65 years, without hematopoietic disorders, and/or history of malignancies, evidence of acute infections, chronic inflammatory status, and history of glucocorticoid therapy within the past three months, hospitalized in the Unit of Internal Medicine, University of Catania, Catania, Italy from January 2014 to December 2016. All patients underwent blood sampling for white blood cell, neutrophil, lymphocyte and platelet counts, and for measurements of inflammatory markers, NLR was calculated as the ratio of the absolute neutrophil count to the absolute lymphocyte count. Patients also underwent carotid scan by ultrasonography (US) to evaluate abnormalities of carotid wall. NLR resulted a strong predictor of the presence of carotid plaques. NLR > 2.4 predicted with 80% probability carotid plaques (p  3.68 gave 97% probability (p = 0.013). Furthermore, NLR > 2.4 was associated with an average presence of 2.86 carotid plaques (p
