Changes of NADH Fluorescence from the Skin of Patients with Systemic Lupus Erythematosus.

Changes of NADH fluorescence indicate the reduction in NADH restoration, observed especially during reperfusion, and suggest the occurrence of disorders in the microcirculation of the skin and/or at the mitochondrial level. Such changes of NADH during reperfusion in patients with SLE could be associated with their possible lower sensitivity to hypoxia and possibly with endothelial dysfunction.
