A controlled, randomized study using an experimental model of contrast (iopromide)-induced nephropathy (CIN) in normal mongrel rats showed that the combination of treatment by hydration with the nicotinamide adenine dinucleotide (NAD)-containing formulation Nadcin, with cytoprotective and antiischemic actions, decreased the plasma creatinine and urea nitrogen levels 72 h after induction of CIN. Aclose correlational relationship ( r = 0.78, p 0.05) or between the ET-1 level and catalase activity ( r = 0.41, p > 0.05). In contrast to monotherapy with hydration, inclusion of Nadcin normalized blood ET-1 and the blood ET-1/creatinine ratio, the blood and renal NAD/NADH and NADP/NADPH redox potentials, and had more marked actions on reversing the overproduction of free radicals and on the antioxidant defense system in the blood and renal tissue. It is suggested that ET-1, the ET-1/creatinine ratio, and the plasma redox potential can be used as early markers for increases in the risk of developing stable impairment of renal function on use of x-ray contract agents.
