Risk Factors and Reversibility of Renal Failure in Patients with Newly Diagnosed Multiple Myeloma

patients with MM. Methods: Patients newly diagnosed with MM from 2005 to 2008 were included. We investigated factors associated with renal insufficiency and those related to recovery from renal dysfunction after 12 weeks of treatment of MM. Results: Renal failure was recognized in 86 (39%) of 221 patients at diagnosis. In the binary logistic regression analysis, low hemoglobin (odds ratio [OR], 0.813; p = 0.02), high β2microglobulin (OR, 1.006; p < 0.01), and use of angiotensin-converting enzyme inhibitors (ACEi) (OR, 2.783; p < 0.04) at initial presentation were independent risk factors for renal failure in patients with multiple myeloma. After 12 weeks of treatment, 25 of 86 (29%) patients with renal failure had recovered renal function. Good response to chemotherapy (OR, 6.044; p < 0.01) and higher eGFR (OR, 1.084; p < 0.01) were associated with renal function recovery. Conclusions: Levels of hemoglobin and β2microglobulin, and use of ACEi were independent risk factors for the development of renal failure in MM patients. The response to chemotherapy and eGFR at diagnosis significantly influenced recovery of renal function. (Korean J Med 2014;86:190-197)
