Cholecalciferol levels, inflammation and leukocytes parameters: Results from a large single-centre cohort of patients

Vitamin D deficiency represents a pandemic health problem with a broad spectrum of clinical implications. Several studies have involved lower levels of vitamin D with inflammatory disorders including cardiovascular, autoimmune and infectious disease. Indeed, the pathophysiological mechanisms are still poorly ascertained. We aimed at evaluating the impact of cholecalciferol (25(OH)D) levels on the biomarkers of acute-phase response and inflammation in a large cohort of patients with cardiovascular disease. Consecutive patients undergoing coronary angiography were included. Main clinical features and chemistry parameters were assessed at admission. 25(OH)D levels were measured by chemiluminescence immunoassay kit LIAISON® Vitamin D assay (Diasorin Inc, Stillwater, US). Hypovitaminosis D was defined for 25(OH)D
