In order to investigate the influence of 25-hydroxyvitamin D (25-OHD) levels on vascular function in ALL survivors, Muggeo et al. [89] evaluated the biochemical and hemostatic markers of endothelial function (ET-1, high-molecular weight adiponectin, thrombin–antithrombin complex, vWF antigen, D-dimers, fibrinogen, and high-sensitive C-reactive protein) and ultrasound markers of vascular endothelial function (FMD, cIMT, and the anteroposterior diameter of the infrarenal abdominal aorta); 52 ALL survivors and 40 matched HCs were compared. This evidence concerns the gene ADIPOQ and acute lymphoblastic leukemia.
