Waldenstrm macroglobulinemia (WM) is a rare B-cell malignancy defined by the World Health Organization as infiltration of lymphoplasmacytic lymphoma in the bone marrow with associated hypersecretion of immunoglobulin M (IgM) monoclonal protein, belonging to the non-Hodgkin B lymphoma category ( Swerdlow et al., 2016 ). Predictors of symptomatic hyperviscosity in Waldenstrm macroglobulinemia. HHS Vulnerability Disclosure, Help This included a triad of mucosal bleeding, visual alterations, and neurologic abnormalities and was consistent with reports of increased serum viscosity in multiple myeloma previously documented between 1932 and 1937. MR MacKenzie, TK Lee; Blood viscosity in Waldenstrom macroglobulinemia.

Am J Hematol. who have demonstrable serum immunoglobulin M monoclonal protein. Nerve conduction studies may show axonal degeneration in patients with longstanding sensorimotor neuropathy or amyloidosis; small fiber neuropathy may also be seen. Clin Hemorheol Microcirc. A 74-year-old woman was diagnosed with WM 7 years ago. These fixed-duration alkylator-free regimens, even without maintenance, offer prolonged progression free survival (PFS).48,54 A randomized prospective study (ECWM-1) comparing DRC vs DRC with bortezomib in previously untreated symptomatic patients has completed accrual. Positron emission tomography does not seem to offer additional information,28 but if transformation to an aggressive lymphoma or another malignancy is suspected, positron emission tomography/CT may be used to biopsy the most fluorodeoxyglucoseavid lesion. For patient 4, repeating DRC43 or starting BR was discussed. Given the available treatment options, these drugs are seldom considered for salvage therapy. government site. Viscosity, Serum - High serum viscosity may be most commonly observed in patients with Waldenstrm's macroglobulinemia and multiple myeloma. Mean serum IgM levels for all 10 spiking patients rose from 4370 (range, 655-7940) to a peak of 5865 (range, 872-11 800) mg/dl (P=0.004), which occurred at a mean of 4 (range, 1-8) weeks following initiation of therapy. [6], The physical exam is consistent with hyperviscosity syndrome, presenting with symptoms of neurologic dysfunction such as headache and fatigue, bleeding diathesis such as epistaxis, and visual abnormalities associated with retinopathy. Abrupt increases in serum IgM levels commonly occur following rituximab therapy in WM. An official website of the United States government. Data from CLL indicate that probably there is no difference, but according to iNNOVATE data, in patients with MYD88WT, ibrutinib with rituximab may be preferable to ibrutinib alone,64 as these patients seem to have similar outcomes to those bearing MYD88L265P. The site is secure. A LPL without monoclonal IgM present or secreting monoclonal non-IgM is not WM, although the biology may not differ significantly. The disease may have an asymptomatic phase, or patients may present with symptoms and complications resulting from marrow or other tissue infiltration, or from physicochemical or immunological properties of the monoclonal IgM. Hyperviscosity in plasma cell dyscrasias. CXCR4 mutation; MYD88 mutation; Waldenstrm macroglobulinaemia; hyperviscosity; immunoglobulin M. MeSH High serum viscosity may be most commonly observed in patients with Waldenstrm's macroglobulinemia and multiple myeloma.

[3][5] Viscosity is highest in small venules; therefore, the force exerted by viscous fluids will tear the venule wall, resulting in microvascular bleeding. 2009 Mar;9(1):56-8. doi: 10.3816/CLM.2009.n.014. About 19% to 28% of patients have asymptomatic WM8,29 and can remain asymptomatic for several years; median time to symptom development may exceed 5 to 10 years.8,30,31Table 4 depicts indications to start therapy31,32; however, clinical judgement is required. She had anemia (hemoglobin, 9.8 g/dL) and 2.5 g/dL of IgM(), and BM had 80% LPL infiltration. For patients presenting with or at risk for hyperviscosity, severe cryoglobulinemia or cold agglutinin disease, plasmapheresis should be considered. Haematologica. In younger patients, deeper responses may be the goal; short-term toxicity is better tolerated, but long-term toxicity (secondary malignancies, MDS, disease transformation resulting from exposure to alkylators, nucleoside analogs, or prolonged immunosuppression) is of concern; thus, alkylator-free regimens such as BDR may be preferable. Keywords: Your comment will be reviewed and published at the journal's discretion. In the early stages of Waldenstrom macroglobulinemia, it is postulated that small retinal hemorrhages are seen in the far periphery that can be observed on indirect ophthalmoscopy with scleral depression. Waldenstroms Macroglobulinemia - CancerCare WebSymptoms of hyperviscosity begin when serum viscosity is >4 centipoises (normal 1.8). Rapidly progressing neuropathy should alert for alternate causes. and E.K. This syndrome occurs most typically in Waldenstroms macroglobulinemia when the monoclonal IgM concentration exceeds 5 g/dl or when serum viscosity is greater than 4.0 centipoises (cp) . Clipboard, Search History, and several other advanced features are temporarily unavailable. Semin Thromb Hemost. P denotes patient required A close follow-up and clinical evaluation is important, and he was followed clinically at 3-month intervals, at least for the first couple of years, to evaluate the pace of the disease. Would you like email updates of new search results? For patients with an IgM >=3,000 mg/dL, a stratified hazard analysis was performed to compare the risk of HVS associated with increasing serum IgM levels. [3]. Although maintenance rituximab could provide some clinical benefit, according to retrospective data,83 it cannot be recommended because of the lack of prospective data in WM; the results of the MAINTAIN study, which compares 2 years of rituximab maintenance vs no maintenance after BR, are awaited. 2000 May-Jun;47(33):842-5. In the case of isolated cardiac involvement in an elderly male patients with WM, evaluation for ATTRwt should also be performed.27 Computed tomography (CT) or magnetic resonance imaging are useful for evaluation of organomegaly and lymphadenopathy. Management of patients that relapse after rituximab-based therapy. The most rapidly acting therapy, whenever immediate IgM reduction is required (such as for hyperviscosity, symptomatic cryoglobulinemia, severe hemolysis resulting from cold agglutinin disease, etc) is plasmapheresis (Figures 1 and 2); blood warmers should be considered during apheresis if cryoglobulins are present.39 After 2 to 3 plasmapheresis sessions, IgM levels can be reduced significantly, but the effect is only transient, and systemic therapy is required. This page was last edited on April 4, 2023, at 16:02. Waldenstrom macroglobulinemia is characterized by cytopenia due to bone marrow infiltration, anemia, lytic bone disease, organomegalies, diffuse pulmonary infiltrates or pleural effusion due to lymphoplasmacytic infiltration of the parenchyma, and malignant infiltration of the bowel, stomach, skull base, orbit, and CNS. Ibrutinib (monotherapy or with rituximab) is very active, but the risk for AF is higher in the elderly,81,82 and treatment may be challenging in those with cardiac comorbidities or in need of anticoagulation or double-antiplatelet therapy or in those receiving drugs that interact with ibrutinib. Additionally, having a pre-existing IgMMonoclonal Gammopathy of Undetermined Significance (MGUS) significantly increases the risk of developing WM later in life. Introduction: Hyperviscosity syndrome (HVS) is a clinical feature associated with Waldenstrm macroglobulinemia (WM).
