Bone morphogenic protein-7 serum level decreases significantly in patients with contrast-induced nephropathy

Background and Aim Previous studies have demonstrated that endogenous bone morphogenic protein-7 (BMP-7) level is reduced in acute kidney injury and administration of exogenous BMP-7 has a beneficial effect on kidney function. In spite of preventive management, contrast-induced nephropathy (CIN) is still the third cause of acute deterioration of kidney function in hospitalized patients. With this background in mind, we studied changes in serum BMP-7 in a group of patients with chronic kidney disease and contrast-induced nephropathy.
