Vitamin D prevents endothelial damage induced by increased neutrophil extracellular traps formation in patients with systemic lupus erythematosus.

Aim: to investigate the effects of Vitamin D calcitriol/1,25(OH)2D3 on NETosis in systemic lupus erythematosus (SLE) patients with hypovitamin D.

Methods: neutrophlis of five SLE patients with hypovitamin D were divided into 4 groups, P0 (0 nM/control), P1 (1 nM), P2 (10 nM), and P3 (100 nM) as cultured samples. Phorbol Myristate Acetate (PMA) was used to stimulate NETs formation.
