Abstract
BACKGROUND Multiple myeloma is a malignant tumour of the blood in which abnormal proliferation of plasma cells leads to bone destruction, renal impairment, anaemia, and hypercalcaemia. Renal impairment caused by multiple myeloma is a common and serious condition; however, the prognosis of multiple myeloma at the time of diagnosis remains unclear. METHOD We conducted searches for literature in PubMed, Web of Science, Cochrane, Embase, CNKI, Wanfang, and VIP databases up to 30 April 2023. Progression-free survival and overall survival with and without renal impairment at the time of multiple myeloma diagnosis were compared, and prognostic indicators were analysed. RESULTS Six studies were finally included. Among patients with multiple myeloma, 319 had renal impairment, and 1166 had no renal impairment. Compared to the control group, no significant difference was observed in overall or progression-free survival in patients with multiple myeloma complicated with renal impairment. CONCLUSION The limited low-quality evidence available does not support an association between prognosis and multiple myeloma complicated by kidney injury.

Abstract
Multiple myeloma (MM) is a haematological lymphoid malignancy involving tumoural plasma cells and is usually characterized by the presence of a monoclonal immunoglobulin protein. MM is the second most common haematological malignancy, with an increasing global incidence. It remains incurable because most patients relapse or become refractory to treatments. MM is a genetically complex disease with high heterogeneity that develops as a multistep process, involving acquisition of genetic alterations in the tumour cells and changes in the bone marrow microenvironment. Symptomatic MM is diagnosed using the International Myeloma Working Group criteria as a bone marrow infiltration of ≥10% clonal plasma cells, and the presence of at least one myeloma-defining event, either standard CRAB features (hypercalcaemia, renal failure, anaemia and/or lytic bone lesions) or biomarkers of imminent organ damage. Younger and fit patients are considered eligible for transplant. They receive an induction, followed by consolidation with high-dose melphalan and autologous haematopoietic cell transplantation, and maintenance therapy. In older adults (ineligible for transplant), the combination of daratumumab, lenalidomide and dexamethasone is the preferred option. If relapse occurs and requires further therapy, the choice of therapy will be based on previous treatment and response and now includes immunotherapies, such as bi-specific monoclonal antibodies and chimeric antigen receptor T cell therapy.

Extracorporeal light-chain elimination in myeloma with simple medium cutoff membrane hemodialysis: a retrospective cohort study. Front Oncol 2023; 13:1193504. [PMID: 37746285 PMCID: PMC10514899 DOI: 10.3389/fonc.2023.1193504] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2023] [Accepted: 08/14/2023] [Indexed: 09/26/2023] Open
Abstract
Background We determined the efficacy of free light chain (FLC) removal by regular dialysis equipment (high-flux filtration) with medium cutoff (MCO) membrane hemodialysis (HD) as an adjuvant treatment to standard chemotherapy for patients with acute kidney injury complicating multiple myeloma (MM) and its impact on further dialysis dependency. Methods Sixty patients with acute dialysis-dependent renal failure secondary to MM were treated with MCO-HD (55 patients) or HCO (high cutoff)-HD (5 patients) as a control. FLC serum concentration, total protein, immunoglobulins, and LDH were measured throughout the dialysis therapy. The kidney function of the patients was followed up for 1 year. Results The median age was 69 years; 25 female and 35 male patients were enrolled. HD significantly reduced FLC kappa levels in the MCO/HCO group by 58%/84% (MCO/HCO group; p < 0.05) and FLC lambda by 39%/33% (MCO/HCO group; p < 0.05). Single HD data (MCO) showed a relative reduction of 70% in kappa and 37% in lambda FLC concentration, as expected by the different sizes of the light chains. Renal function improved significantly and continuously from starting creatinine 5.7/3.8 mg/dl (MCO/HCO group) before HD to 1.4/2.0 mg/dl (MCO/HCO group; p < 0.001) after 1 year. No significant alteration of total protein, immunoglobulins, and LDH concentrations by HD (HCO and MCO group) was observed. After 1 year, 37 of 60 patients were alive and 34 of them were off dialysis. Conclusion FLC elimination with MCO-HD is effective, technically easy, and less cost-intensive as compared with HCO-HD. Kidney function recovery in MM patients is achievable.

Abstract
PURPOSE Patients with multiple myeloma (MM) are prone to developing persistent renal insufficiency. Novel therapeutic medications have improved long-term survival, making kidney transplantation (KT) a viable treatment option for MM survivors with end-stage renal disease. This study aimed to investigate the clinical outcomes in patients with MM who have received KT. METHODS Data from hospitalized patients ≥ 40 years of age with MM in the Nationwide Inpatient Sample 2016-2018 of the United States were queried. Patients were classified as having or not having undergone KT, as well as the stage of chronic kidney disease (CKD) for those who had not received KT. Propensity-score matching (PSM) was applied to balance the characteristics between the groups. Binary logistic regression was utilized to determine the associations between study variables and inhospital mortality, unfavorable discharges, prolonged length of stay (LOS), and major complications. RESULTS In total, 50,654 hospitalized patients with MM were identified, of whom 165 (0.3%) had received KT and 50,489 had not (5,905 at stage 5 CKD [CKD5D], 11,559 at stage 1-4 CKD [CKD1-4D], and 33,025 who were CKD-free). After PSM, between-group demographic and hospital-related characteristics were balanced. Binary regression analysis revealed that, compared to patients who were CKD-free, patients at CKD5D were significantly more likely to experience a prolonged LOS (odds ratio [OR], 1.31; 95% confidence interval [CI], 1.01-1.70) after adjusting for relevant confounders. Furthermore, compared to CKD-free patients, those who underwent KT were significantly more likely to have sepsis (OR, 1.48; 95% CI, 1.02-2.14). However, KT showed no association with the other adverse inpatient outcomes. CONCLUSION Although KT is not common in MM patients, those who had undergone KT had comparable hospital outcomes to CKD-free patients. These data will help clinicians deliver better consultations to MM patients attempting to receive KT.

Abstract
Multiple myeloma (MM) patients risk diagnostic delays and irreversible organ damage. In those with newly diagnosed myeloma, we explored the presenting symptoms to identify early signals of MM and their relationships to organ damage. The symptoms were recorded in patients' own words at diagnosis and included diagnostic time intervals. Those seen by a haematologist >6 months prior to MM diagnosis were classified as precursor disease (PD). Most (962/977) patients provided data. Back pain (38%), other pain (31%) and systemic symptoms (28%) predominated. Patients rarely complain of 'bone pain', simply 'pain'. Vertebral fractures are under-recognised as pathological and are the predominant irreversible organ damage (27% of patients), impacting the performance status (PS) and associated with back pain (odds ratio (OR) 6.14 [CI 4.47-8.44]), bone disease (OR 3.71 [CI 1.88-7.32]) and age >65 years (OR 1.58 [CI 1.15-2.17]). Renal failure is less frequent and associated with gastrointestinal symptoms (OR 2.23 [CI1.28-3.91]), age >65 years (OR 2.14 [CI1.28-3.91]) and absence of back pain (OR 0.44 [CI 0.29-0.67]). Patients with known PD (n = 149) had fewer vertebral fractures (p = 0.001), fewer adverse features (p = 0.001), less decline in PS (p = 0.001) and a lower stage (p = 0.04) than 813 with de novo MM. Our data suggest subgroups suitable for trials of 'symptom-directed' screening: those with back pain, unexplained pain, a general decline in health or low-impact vertebral compression fractures.

Abstract
Light chain cast nephropathy (LCCN) is a leading cause of acute kidney injury (AKI) in patients with multiple myeloma (MM) and is now defined as a myeloma defining event. While the long-term prognosis has improved with novel agents, short-term mortality remains significantly higher in patients with LCCN especially if the renal failure is not reversed. Recovery of renal function requires a rapid and significant reduction of the involved serum free light chain. Therefore, proper treatment of these patients is of the utmost importance. In this paper, we provide an algorithm for treatment of MM patients who present with biopsy-proven LCCN or in those where other causes of AKI have been ruled out. The algorithm is based on data from randomized trial whenever possible. When trial data is not available, our recommendations is based on non-randomized data and expert opinions on best practices. We recommend that all patients should enroll in a clinical trial if available prior to resorting to the treatment algorithm we outlined.

Abstract
Immune therapies, including CAR-T cells, bispecific antibodies, and antibody-drug conjugates, are revolutionizing the treatment of multiple myeloma. In this review, we discuss clinical trial design considerations relevant to immune therapies. We first examine issues pertinent to specific populations, including elderly, patients with renal impairment, high-risk/extramedullary disease, and prior immune therapies. We then highlight trial designs to optimize the selection of dose and schedule, explore rational combination therapies based on preclinical data, and evaluate the nuances of commonly used endpoints. By exploiting their pharmacokinetic/pharmacodynamic profiles and utilizing novel translational insights, we can optimize the use of immune therapies in multiple myeloma.

Lack of Renal Recovery Predicts Poor Survival in Patients of Multiple Myeloma With Renal Impairment. CLINICAL LYMPHOMA, MYELOMA & LEUKEMIA 2022; 22:626-634. [PMID: 35610119 DOI: 10.1016/j.clml.2022.04.013] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/01/2022] [Revised: 04/04/2022] [Accepted: 04/10/2022] [Indexed: 11/17/2022]
Abstract
BACKGROUND Renal impairment (RI) confers a poor prognosis in multiple myeloma. Reversibility of renal function is associated with improved survival in such patients. Patients in developing countries often present at an advanced stage and renal impairment is present in up to 40% of patients at diagnosis. We studied the renal outcome and survival of these patients with bortezomib-based induction therapy. MATERIALS AND METHODS It was a single-center prospective study in a tertiary care multi-specialty institute in patients of newly diagnosed multiple myeloma (NDMM) who presented with RI from July 2018 to December 2019. The diagnosis of multiple myeloma was made based on IMWG14 criteria. All patients received bortezomib and or immunomodulatory drug-based triplet or quadruplet induction therapy. Hematological and renal outcomes were assessed as per IMWG 2016 criteria. RESULTS Among 216 consecutive patients of NDMM, RI was seen in 91 (42.2%) patients. The median age of 91 patients was 60 years. (range- 32-80 years). Light chain myeloma was seen in 26% (n = 24) of patients. The median estimated glomerular filtration rate (eGFR) was 15.36 mL/min (3.1-38 mL/min) and a majority of patients were in the advanced ISS stage. (ISS III = 85.7%). Thirty-six (39.5%) patients received hemodialysis at presentation. Renal response was seen in 67 (73%) patients and 20 (out of 36; 55%) became dialysis independent over a median time of 38 days (Range 15-160 days). At a median follow-up of 14.7 months, 30 (33%) patients had died, of which, 14 (15.4%) patients had early mortality (within 2 months of diagnosis). Presence of light chain myeloma and cast nephropathy (definite or probable) were identified as independent predictors of poor renal recovery on multivariate analysis. (HR = 2.841; 95% CI [1.471-5.486], P = .002 for light chain myeloma; HR = 1.859; 95% CI (1.087-3.180); P = .024 for cast nephropathy) Patients with low eGFR at presentation (<12.5 mL/min) were more likely to have persistent renal insufficiency. (HR-3.521; 95% CI (1.856-6.679), P = .000). Patients who attained sustained renal recovery had improved survival as compared to patients in whom renal function failed to improve. (median OS- not reached vs. 8.3 months, P = .000) Achievement of hematological response and independence from hemodialysis was associated with improved survival on multivariate analysis. CONCLUSION Renal impairment was reversible in almost three-fourths of NDMM patients. achievement of hematological response and hemodialysis independence were independent predictors of improved overall survival in NDMM patients with RI.

Abstract
BACKGROUND Recent improvement in treatment and patient survival has opened the eligibility of kidney transplantation to patients who developed end-stage kidney disease (ESKD) from plasma cell dyscrasias (PCDs). Data on clinical outcomes in this population are lacking. METHODS We conducted a retrospective study of United Network for Organ Sharing/Organ Procurement and Transplantation Network dataset (2006-2018) to compare patient and graft outcomes of kidney transplant recipients with ESKD due to PCD versus other causes. RESULTS Among 168 369 adult first kidney transplant recipients, 0.22-0.43% per year had PCD as the cause of ESKD. The PCD group had worse survival than the non-PCD group for both living and deceased donor types {adjusted hazard ratio [aHR] 2.24 [95% confidence interval (CI) 1.67-2.99] and aHR 1.40 [95% CI 1.08-1.83], respectively}. The PCD group had worse survival than the diabetes group, but only among living donors [aHR 1.87 (95% CI 1.37-2.53) versus aHR 1.16 (95% CI 0.89-1.2)]. Graft survival in patients with PCD were worse than non-PCD in both living and deceased donors [aHR 1.72 (95% CI 1.91-2.56) and aHR 1.30 (95% CI 1.03-1.66)]. Patient and graft survival were worse in amyloidosis but not statistically different in multiple myeloma compared with the non-PCD group. CONCLUSION The study data are crucial when determining kidney transplant eligibility and when discussing transplant risks in patients with PCD.

Bergner R, Hoffmann M, Uppenkamp M, Paschka P, Klank D. The urine light chain/glomerular filtration rate (GFR) quotient shows a high sensitivity and specificity to detect cast nephropathy in monoclonal light chain disease. Eur J Haematol 2021; 106:836-841. [PMID: 33725381 DOI: 10.1111/ejh.13616] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2020] [Revised: 03/01/2021] [Accepted: 03/03/2021] [Indexed: 11/27/2022]
Abstract
BACKGROUND Cast nephropathy (CN) is associated with a unfavourable outcome in monoclonal light chain (mLC) disease, but also more possible LC-related renal diseases as well as non-LC-related disease can occur. Thus, it is crucial to understand the underlying renal disease. On the other hand, LC can interfere with coagulation preventing kidney biopsy as the gold standard. We sought to develop a non-invasive algorithm to diagnose CN with a good sensitivity and specificity. METHOD We analysed data from patients with mLC disease who underwent kidney biopsy. The patients were classified in 4 groups according the renal histology: CN, AL amyloidosis, light chain deposition disease, and other renal disease. Afterwards, different algorithms were calculated for their sensitivity and specificity. RESULTS CN showed a significant higher concentration of serum-free LC and urine LC (LCu), but there was a wide and overlapping range with the other groups. The best accuracy was achieved for a LCu/GFR ratio >2 in patients with lambda LC and either a LCu/GFR > 1 and proteinuria <8 g/24 h or a LCu/GFR > 5 in patients with proteinuria >8 g/24 h in patients with kappa LC. In lambda LC, the sensitivity and specificity for CN was 94% and 90%, respectively; in kappa LC 87% and 81%, respectively. DISCUSSION In patients with coagulation disturbances due to LC, a non-invasive algorithm can separate patients with CN from other renal disease in mLC disease.

Abstract
Myeloma-related kidney disease has several manifestations; the 2 most common histologic diagnoses are myeloma cast nephropathy and acute tubular necrosis. We describe a case of different kidney pathologies occurring concomitantly in a patient found to have immunoglobulin A κ multiple myeloma. A White woman in her 70s presented with an 8-month history of back pain and was found to have nephrotic-range proteinuria and acute kidney injury. Serum calcium level was 12.6 mg/dL. Kidney biopsy showed κ light chain only proliferative glomerulonephritis with monoclonal immunoglobulin deposits, crystalglobulinemia, light chain proximal tubulopathy with κ light chain deposits, mild tubular atrophy, and interstitial fibrosis. Free κ light chain ratio was >1,000 mg/dL and free κ light chain level was 4,670 mg/dL. Within a week following treatment of hypercalcemia and initiation of chemotherapy, her acute kidney injury and hypercalcemia resolved. This case highlights the many kidney manifestations of multiple myeloma and that prompt management targeting these manifestations, including hypercalcemia, can improve clinical outcomes.

Real world analysis of high-cut-off (HCO) hemodialysis with bortezomib-based backbone therapy in patients with multiple myeloma and acute kidney injury. J Nephrol 2020; 34:1263-1270. [PMID: 33382447 PMCID: PMC8357738 DOI: 10.1007/s40620-020-00939-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2020] [Accepted: 11/30/2020] [Indexed: 10/27/2022]
Abstract
BACKGROUND In patients with multiple myeloma (MM) free light chain-induced cast nephropathy is a serious complication associated with poor survival. High-cut-off (HCO) hemodialysis can reduce the amount of serum free light chains (sFLC), but data on its impact on clinical outcome is limited and contradictory. To gain further insights we collected real world data from two major myeloma and nephrology centers in Austria and the Czech Republic. METHODS Sixty-one patients with MM and acute kidney injury, who were treated between 2011 and 2019 with HCO hemodialysis and bortezomib-based MM therapy, were analyzed. RESULTS The median number of HCO hemodialysis sessions was 11 (range 1-42). Median glomerular filtration rate at diagnosis was 7 ± 4.2 ml/min/1.73m2. sFLC after the first HCO hemodialysis decreased by 66.5% and by 89.2% at day 18. At 3 and 6 months, 26 (42.6%) and 30 (49.2%) of patients became dialysis-independent. CONCLUSION The widely used strategy combining HCO hemodialysis and bortezomib-based antimyeloma treatment is dissatisfactory for half of the patients undergoing it and clearly in need of improvement.
