Abstract
Presentation with severe acute kidney injury due to cast nephropathy (CN) is a medical emergency in multiple myeloma (MM), with high risk of dialysis-dependent renal failure and death. Accrual of patients with CN into interventional studies is difficult, while phase III trials exclude patients with severe renal insufficiency. Real-world data are warranted. We assessed 2252 patients from the population-based Danish Multiple Myeloma Registry (DMMR) who were diagnosed between 2013 and 2017. We identified 204 patients with clinically-suspected CN, defined as serum creatinine concentration >177 μmol/L and serum free light chain (sFLC) concentration >1000 mg/L at the time of diagnosis. The median age was 72 years. Thirty-one percent of patients presented with dialysis-dependent renal failure. Kidney biopsies were performed in 19% of patients and showed CN in 74% of cases. Despite prompt initiation of bortezomib-based therapy in 94% of patients, 33% of patients died in the first year after diagnosis. Compared with the rest of the patients in the DMMR with symptomatic MM, patients with clinically-suspected CN had worse overall survival (OS) irrespective of transplant eligibility. Achievement of renal recovery was associated with deep reductions of involved sFLC. Achievement of very good partial response or better in the first line of therapy and/or deep reduction of involved sFLC at 3 months after initiation of therapy were associated with superior OS. In conclusion, MM patients presenting with clinically-suspected CN have an alarmingly high one-year mortality when treated with current standards of care. Early and deep hematologic response is crucial for survival.

Abstract
Multiple Myeloma is a plasma cell proliferative disorder that commonly involves the kidney. Renal impairment is a serious complication during the course of the disease that is associated with increased morbidity and mortality. Light chain cast nephropathy is the predominant pattern of renal injury in Multiple Myeloma. This review article focuses on the pathophysiology and diagnostic approach of myeloma cast nephropathy. The management of precipitating factors as well as anti-plasma cell treatment modalities in the context of renal impairment are also discussed.

Abstract
PURPOSE OF REVIEW Renal failure is a frequent complication of multiple myeloma and portends a poor prognosis. Plasmapheresis has been suggested as an adjunct to chemotherapy to halt or reverse renal injury associated with multiple myeloma. The purpose of this article is to review the rationale for using plasmapheresis for this indication and then provide a discussion of the evidence regarding its use. RECENT FINDINGS The outcome of patients with multiple myeloma has improved considerably in recent years, mostly owing to the introduction of new highly effective chemotherapeutic agents. However, patients with renal failure who do not recover independent renal function continue to have very poor prognosis. Recent evidence now indicates that an early and sustained reduction in circulating free light chains (FLCs) is associated with improved renal recovery in patients with myeloma kidney. Extracorporeal removal of FLCs with plasmapheresis, or other techniques, can achieve rapid and sustained reduction in serum FLC concentration in patients with acute myeloma kidney. Unfortunately, there is currently no convincing evidence in the literature that the addition of mechanical removal of FLC to standard chemotherapy translates into clinical benefits for patients. SUMMARY Plasmapheresis is theoretically attractive as a means of rapidly lowering serum FLC burden in the hope of reducing nephrotoxicity in patients with multiple myeloma. However, the role of plasmapheresis in improving renal prognosis and patient survival remains to be demonstrated.

Abstract
OBJECTIVES The aim of this study was to report the long-term outcomes in patients with multiple myeloma (MM) who receive dialysis treatment for acute kidney injury (AKI) due to myeloma cast nephropathy and subsequently recover renal function. METHODS Patients presenting with dialysis-dependent AKI secondary to myeloma cast nephropathy and subsequently recovering independent renal function between January 2005 and December 2012 were included in this study. Both renal and haematological parameters were collected at multiple time points as part of routine clinic practice. Factors associated with renal function and overall survival (OS) were determined. RESULTS Twenty-four patients fulfilled the criteria for inclusion. Mean age was 62.1 years; 75% were male and 75% were of White ethnicity. The median OS was 64.1 months (95% confidence interval [CI] 34.8-93.3). Twenty-three (95.8%) patients remained dialysis-independent until death or end of follow-up; one patient required further haemodialysis treatment during the follow-up period. The independent determinant of worse OS was a known history of chronic kidney disease (CKD) at presentation. Shorter length of time on haemodialysis and higher percentage reduction in clonal serum FLC at day 21 from baseline predicted better excretory renal function (estimated glomerular filtration rate) at 6 months. CONCLUSION In this series, the large majority of patients with MM and dialysis-dependent AKI secondary to myeloma cast nephropathy who recovered independent renal function had no requirement for further dialysis. Survival following recovery of renal function is good, and early variables are independently associated with survival and future renal function.

Abstract
Myeloma kidney (cast nephropathy) causing severe acute kidney injury occurs in up to 10% of patients with multiple myeloma. The lesion is caused by exposure of the kidneys to high serum levels of free clonal immunoglobulin light chains (LCs) and is associated with very high morbidity and mortality. The current focus on the management of this complication is on early and aggressive treatment to rapidly reduce the serum levels of the immunoglobulin LC clone and protect the kidneys from continuing injury. This has promoted intense interest in the role of direct (extracorporeal) removal of free LCs from serum by plasma exchange or high cut-off (protein permeable) hemodialysis. However, it remains uncertain whether direct removal provides an additional measurable clinical benefit over the current standard of care; rapid institution of treatment with a dexamethasone- and bortezomib-based chemotherapy regime. In this article, we review the rationale for direct removal of free LCs and the current clinical evidence base for plasma exchange and high cut-off hemodialysis.

Abstract
Myeloma kidney is a tubulointerstitial pathology that accounts for approximately 80-90% of severe acute kidney injury in patients with multiple myeloma. Unless there is rapid intervention, progressive irreversible damage from interstitial fibrosis and tubular atrophy occurs. Work over the past decade has demonstrated that an early sustained reduction in serum concentrations of pathogenic monoclonal free light chains (FLCs) leads to improved renal recovery rates. In turn, an early improvement in renal function is associated with improved patient survival. An early reduction in FLC levels should therefore become standard of care, although the optimum mechanisms to achieve this depletion of FLCs remain to be determined. To provide a coordinated, cross-disciplinary approach to research in this disease, the International Kidney and Monoclonal Gammopathy Research Group was formed. In this Review, we address the current state of knowledge in the management of myeloma kidney.

Abstract
BACKGROUND Approximately 10-20% of multiple myeloma patients experience dialysis-dependent renal failure. This is principally due to myeloma kidney, a tubulointerstitial injury caused by high circulating concentrations of monoclonal free light chains. Studies have found that between 3% and 37% of patients with myeloma kidney requiring dialysis recover renal function. In-vivo studies indicate that extended haemodialysis using high cut-off dialysers (HCO-HD) can remove significant quantities of free light chains and is associated with a renal recovery rate of 63-74% in these patients. OBJECTIVE The objective of this study was to assess the cost-effectiveness of HCO-HD compared to standard HD in the management of myeloma kidney. METHODS The study used a lifetime Excel-based decision tree model that followed all patients from treatment of the initial presentation with myeloma kidney requiring dialysis to death. It was populated with published clinical data, United Kingdom costs and expert opinion, using a National Health Service perspective and 3.5% annual discounting. RESULTS HCO-HD was dominant to standard HD, meaning it was both more effective (greater life years and quality adjusted life years) and less costly, due to a greater increase in the proportion of patients recovering renal function. The model projected lifetime costs of £31,345 per patient for patients treated with standard haemodialysis only and £24,845 for the new treatment (discounted). The model predicted an average survival of 19.92 months for patients on standard HD and 33.90 months for the new therapy (discounted). CONCLUSIONS The analysis found that treatment of myeloma kidney using an extended schedule of HCO-HD may substantially improve renal recovery in multiple myeloma patients compared to standard HD, resulting in greater life expectancy and cost savings due to avoided chronic dialysis. Limitations of the study include those common to rare diseases including small study sizes and limited natural history data.

Abstract
BACKGROUND AND OBJECTIVES Extended hemodialysis using a high cut-off dialyzer (HCO-HD) removes large quantities of free light chains in patients with multiple myeloma. However, the clinical utility of this method is uncertain. This study assessed the combination of chemotherapy and HCO-HD on serum free light chain concentrations and renal recovery in patients with myeloma kidney (cast nephropathy) and dialysis-dependent acute renal failure. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS An open-label study of the relationship between free light chain levels and clinical outcomes in 19 patients treated with standard chemotherapy regimens and HCO-HD. RESULTS There were sustained early reductions in serum free light chain concentrations (median 85% [range 50 to 97]) in 13 patients. These 13 patients became dialysis independent at a median of 27 d (range 13 to 120). Six patients had chemotherapy interrupted because of early infections and did not achieve sustained early free light chain reductions; one of these patients recovered renal function (at 105 d) the remaining 5 patients did not recover renal function. Patients who recovered renal function had a significantly improved survival (P < 0.012). CONCLUSION In dialysis-dependent acute renal failure secondary to myeloma kidney, patients who received uninterrupted chemotherapy and extended HCO-HD had sustained reductions in serum free light chain concentrations and recovered independent renal function.

Abstract
BACKGROUND Monoclonal free light chains (FLCs) frequently cause rapidly progressive renal failure in patients with multiple myeloma. Immunoassays which provide quantitative measurement of FLCs in serum, have now been adopted into screening algorithms for multiple myeloma and other lymphoproliferative disorders. The assays indicate monoclonal FLC production by the presence of an abnormal kappa to lambda FLC ratio (reference range 0.26-1.65). Previous work, however, has demonstrated that in patients with renal failure the FLC ratio can be increased above normal with no other evidence of monoclonal proteins suggesting that in this population the range should be extended (reference range 0.37-3.1). This study evaluated the diagnostic sensitivity and specificity of the immunoassays in patients with severe renal failure. METHODS Sera from 142 patients with new dialysis-dependent renal failure were assessed by serum protein electrophoresis (SPE), FLC immunoassays and immunofixation electrophoresis. The sensitivity and specificity of the FLC ratio's published reference range was compared with the modified renal reference range for identifying patients with multiple myeloma; by receiver operating characteristic curve analysis. RESULTS Forty one patients had a clinical diagnosis of multiple myeloma; all of these patients had abnormal serum FLC ratios. The modified FLC ratio range increased the specificity of the assays (from 93% to 99%), with no loss of sensitivity. Monoclonal FLCs were identified in the urine from 23 of 24 patients assessed. CONCLUSION Measurement of serum FLC concentrations and calculation of the serum kappa/lambda ratio is a convenient, sensitive and specific method for identifying monoclonal FLC production in patients with multiple myeloma and acute renal failure. Rapid diagnosis in these patients will allow early initiation of disease specific treatment, such as chemotherapy plus or minus therapies for direct removal of FLCs.

Abstract
Data are presented on 81 multiple myeloma (MM) patients with renal failure (creatinine > 176.8 micromol/l) at the time of autologous stem cell transplantation (auto-SCT), including 38 patients on dialysis. The median age was 53 years (range: 29-69) and 26% had received more than 12 months of prior chemotherapy. CD34+ cells were mobilized with granulocyte colony-stimulating factor (G-CSF) alone (n = 51) or chemotherapy plus G-CSF (n = 27), yielding medians of 10 and 16 x 106 CD34+ cells/kg respectively (P = 0.003). Sixty patients (27 on dialysis) received melphalan 200 mg/m2 (MEL-200). Because of excessive toxicity, the subsequent 21 patients (11 on dialysis) received MEL 140 mg/m2 (MEL-140). Thirty-one patients (38%) completed tandem auto-SCT, including 11 on dialysis. Treatment-related mortality (TRM) was 6% and 13% after the first and second auto-SCT. Median times to absolute neutrophil count (ANC) > 0.5 x 109/l and to platelets > 50 x 109/l were 11 and 41 d respectively. Non-haematological toxicities included mucositis, pneumonitis, dysrhythmias and encephalopathy. At a median follow up of 31 months, 30 patients have died. Complete remission (CR) was achieved in 21 patients (26%) after first SCT and 31 patients (38%) after tandem SCT. Two patients discontinued dialysis after SCT. Median durations of complete remission (CR) and overall survival (OS) have not been reached; probabilities of event-free survival (EFS) and OS at 3 years were 48% and 55% respectively. Dialysis dependence and MEL dose did not affect EFS or OS. Sensitive disease prior to SCT, normal albumin level and younger age were independent prognostic factors for better OS. In conclusion, renal failure had no impact on the quality of stem cell collections and did not affect engraftment. MEL-140 had an acceptable toxicity and appeared equally effective as MEL-200. In the setting of renal failure, the role of auto-SCT early in the disease course and benefits of tandem SCT require further evaluation.
