Multiple Myeloma (MM) is characterized by a neoplastic proliferation of plasma cell clones producing monoclonal immunoglobulin. Manifestations of the disease are heterogenous and include dialysis­‑requiring acute kidney injury (AKI) caused mainly by cast nephropathy (CN). It is known that early and rapid decrease in serum free light chains (sFLC) levels is particularly important for renal recovery, which has led to a renewed interest in extracorporeal methods of removal of sFLC. In this review we will discuss the management of light chain CN focusing on extracorporeal light chains removal modalities and their indication.

Patients with multiple myeloma (MM) are at risk for acquired dysfibrinogenemia resulting in laboratory abnormalities and/or bleeding complications. We describe a 63-year-old man who presented with bleeding diathesis in the presence of a low fibrinogen activity level with a normal fibrinogen antigen level. Further studies revealed elevated levels of lambda free light chains, and he was diagnosed with MM. Despite initiating treatment with bortezomib/dexamethasone, he continued to have recurrent bleeds along with hypofibrinogenaemia, prompting a switch to carfilzomib/dexamethasone. The patient responded with improvement in bleeding symptoms, normalisation of fibrinogen activity and a decrease in serum free light chains.

Abstract Abstract 2927 Background and Aims: Multiple Myeloma (MM) is characterized by bone marrow (BM) plasma cell infiltration and the presence of serum/urine monoclonal immunoglobulin (Ig). The depth of response has been associated with longer PFS in MM causing subsequent prolonged survival. Recently novel M-based biomarker immunoassays have been developed (Freelite™, Hevylite™) and their significance in MM diagnosis and prognosis has been demonstrated.1,2 Furthermore serum Free Light Chains (sFLC) are used for better assessment of treatment response, thus patients are considered to achieve stringed Complete Response (sCR) by having CR criteria plus normal serum Free Light Chains Ratio (sFLCR) and absent clonal cells on BM.3 The significance of Hevylite™ on response has not been assessed so far. Patients in nCR or better do not automatically restore their ratio of intact monoclonal Ig/intact polyclonal Ig of the same class (Hevylite™ or HLCR). We therefore investigated the importance of sFLCR and HLCR normalisation at plateau on PFS, in a series of patients with intact Ig MM. Patients and Methods: 50 intact immunoglobulin MM patients were studied from diagnosis to last follow up. Immunofixation was IgG (26 -kappa and 12 –lamdba) and IgA (6 –kappa and 6 -lambda). All patients were symptomatic at diagnosis. Sera samples (n=312) were analyzed for sFLC-kappa and sFLC-lambda with Freelite™ and sFLCR were calculated, and for IgGkappa, IgGlambda IgAkappa, IgAlambda with Hevylite™ and ratios IgGkappa/IgGlambda, IgGlambda/IgGkappa, IgAkappa,/IgAlambda and IgAlambda/IgAkappa (HLCRs) were calculated. sFLCRs and HLCRs values above the 95%-ile of normal individuals were considered abnormal. Statistical analysis was performed using SPSS ver 15.0. File data were reviewed. Results: At diagnosis sFLCR was abnormal in 86% of patients while HLCR was abnormal in all. All treatment lines were initiated according to standard criteria and median lines of therapy were 2 (range 1–11). Median follow up was 33 months (7–145). During patients' cumulative follow-up, 145 lines of therapy were studied and the subsequent responses were estimated. Thirty eight percent of responses were sCR, CR and nCR, 20% PR, 18% MR and 24% refractory and progressive disease. HLCR normalized in 44% of patients with sCR, CR and nCR. The depth of response correlated to PFS and patients in sCR, CR and nCR had longer PFS than the others (p<0.001). Serum FLCR and HLCR normal values at response were both strong parameters of increased PFS after treatment at any line (p=0.035 and p=0.046 respectively). Conclusion: Serum HLCR normalization at plateau reflects prolonged responses in intact Ig MM. Disclosures: Harding: Binding Site: Employment. Bradwell:The Binding Site: shareholder Other.

Abstract Abstract 5002 Background: Kidney failure is a major cause of morbidity in patients with Multiple Myeloma (MM). While up to half of MM patients can be shown to have renal impairment, 10% will become dialysis dependent. The main mechanism of kidney failure is cast nephropathy, which is linked to high amounts of circulating free light chains. A proposed strategy to prevent this outcome is the use of extended high cutoff (HCO) dialysis. An ongoing randomized controlled trial is testing the Gambro HCO1100 filter. Here we report the use of another dialyzer (Bellco Phylther), which has a smaller pore size than the Gambro filter, but which may prove to be as effective and is less costly. Methods: We present three patients with symptomatic MM, elevated κ or λ serum free light chains (>500mg/L), biopsy confirmed cast nephropathy, and kidney failure (estimated GFR <15ml/min/1.73 m2) requiring dialysis. In all patients, dialysis consisted of 10 hemodiafiltration dialysis sessions in the first two weeks and three times a week thereafter using a high flux Bellco Phylther HF22SD dialyzer (Bellco, Modena, Italy). All patients received concurrent chemotherapy: bortezomib 1.3mg/m2 IV and dexamethasone 40mg po on days 1, 4, 8 and 11 of a 21 day cycle and liposomal doxorubicin at 30mg/m2 on day 4 of every cycle. Serum free light chains were determined pre- and immediately post-dialysis using a nephelometric immunoassay (FREELITE, The Binding Site, Birmingham UK). Results: We observed significant (>50%) and rapid reductions in sFLCs. These reductions were sustained at 3 months in all cases, likely because of effective anti-myeloma treatment. Two of the three patients had recovery of kidney function and remain dialysis-independent at least 6 months after cessation of dialysis. Interestingly, the only patient that did not recover kidney function was also found to have tubulointerstitial disease on renal biopsy in addition to cast nephropathy. Conclusions: The HCO Bellco Phylther dialyzer appears effective in the rapid reduction of sFLCs in light chain MM patients with cast nephropathy requiring dialysis and concurrent anti-myeloma drug therapy. While the numbers are small, our review suggests that patients with uncomplicated MM cast nephropathy may benefit from aggressive hemodiafiltration with this HCO membrane. This dialysis membrane and protocol are worth considering for further study in patients with MM cast nephropathy. Disclosures: No relevant conflicts of interest to declare.
