Iodine-based contrast media, multiple myeloma and monoclonal gammopathies: literature review and ESUR Contrast Media Safety Committee guidelines

Objectives Many radiologists and clinicians still consider multiple myeloma (MM) and monoclonal gammopathies (MG) a contraindication for using iodine-based contrast media. The ESUR Contrast Media Safety Committee performed a systematic review of the incidence of post-contrast acute kidney injury (PC-AKI) in these patients. Methods A systematic search in Medline and Scopus databases was performed for renal function deterioration studies in patients with MM or MG following administration of iodine-based contrast media. Data collection and analysis were performed according to the PRISMA statement 2009. Eligibility criteria and methods of analysis were specified in advance. Cohort and case-control studies reporting changes in renal function were included. Results Thirteen studies were selected that reported 824 iodine-based contrast medium administrations in 642 patients withMMorMG, in which 12 unconfounded cases of PC-AKIwere found (1.6 %). The majority of patients had intravenous urography with high osmolality ionic contrast media after preparatory dehydration and purgation. Conclusions MM and MG alone are not risk factors for PCAKI. However, the risk of PC-AKI may become significant in dehydrated patients with impaired renal function. Hypercalcaemia may increase the risk of kidney damage, and should be corrected before contrast medium administration. Assessment for Bence-Jones proteinuria is not necessary. Key Points \u2022 Monoclonal gammopathies including multiple myeloma are a large spectrum of disorders. \u2022 In monoclonal gammopathy with normal renal function, PCAKI risk is not increased. \u2022 Renal function is often reduced in myeloma, increasing the risk of PC-AKI. \u2022 Correction of hypercalcaemia is necessary in myeloma before iodine-based contrast medium administration. \u2022 Bence-Jones proteinuria assessment in myeloma is unnecessary before iodine-based contrast medium administration
