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. ⋯ The present study demonstrates that, among patients with cardiovascular disease, 25(OH)D deficiency is associated with a higher metabolic and clinical risk profile and with an elevation of cellular and humoral inflammatory parameters. Future dedicated studies should be, therefore, advocated in order to define whether 25(OH)D supplementation can modulate the mediators of the acute phase response and therefore potentially offer clinical and prognostic advantages on a broad spectrum of inflammatory disease.
