Abstract

We report a 73-year-old male with no relevant past medical history who presented with nephrotic syndrome and jaundice. Subsequent studies revealed immunoglobulinM (IgM) monoclonal gammopathy. Kidney biopsy revealed monoclonal Ig deposition disease and amyloidosis. Bone marrow biopsy demonstrated <10% infiltration by lymphoplasmacytic cells. However, rapidly progressive hypergammaglobulinemia of IgM and hyperbilirubinemia were noted. Despite aggressive treatment, the patient developed acute kidney injury and complications of hepatic failure. He eventually died of pneumonia, just two months after diagnosis.

 Introduction



Immunoglobulin M (IgM) monoclonal gammopathy is a spectrum of diseases that range from asymptomatic monoclonal gammopathy of undetermined significance (MGUS) to smoldering Waldenström macro-globulinemia (WM) to symptomatic WM. Kyle et al have shown in a long-term follow-up of 213 patients with IgMMGUS that 2.8% of patients developed WM. It is estimated that the rate of progression of IgMMGUS to symptomatic WM is approximately 1.5% per year.[1] Most patients have an indolent course.

We herein report an unusual case of IgM monoclonal gammopathy of renal significance (MGRS) with a swiftly progressive course.

 Case Report



A 73-year-old male with no special past medical history presented with lower leg edema. Physical examinations of the chest, heart, and abdomen were unremarkable. Neither significant lymphadenopathy nor hepatosplenomegaly was present. Laboratory data included the following values: white blood cell count 3,800/mm3, hemoglobin 13.4 g/dL, platelet count 212,000/mm3, aspartate aminotransferase 57 U/L, alanine aminotransferase 32 U/L, total bilirubin 2.66 mg/dL, creatinine 0.97 mg/dL, calcium 8.7 mg/dL, glucose 85 mg/dL, albumin 2.6 g/dL, IgG 427.0 mg/dL (normal 700–1600), IgA 62.9 mg/dL (normal 70–400), and IgM 2020 mg/dL (normal 40–230). Urine sediments contained red blood cells 3.1/high-power field without casts. Urine protein-to-creatinine ratio was 2324 mg/g. Serologies for antinuclear antibody, hepatitis B, and hepatitis C were negative. Type I cryoglobulinemia was detected. Serum protein electrophoresis disclosed a monoclonal component in the gamma region, which was classified as IgM lambda. Urine immuno-fixation revealed lambda light chains. Radio-graphic imaging of the bones did not show lytic lesions. Computed tomography of the chest and abdomen did not show organo-megaly or lymphadenopathy. Kidney biopsy revealed monoclonal Ig deposition disease, in which the deposits were composed of IgM and lambda light chain [Figure 1]. Congo red stain demonstrated apple-green birefringence under polarized light [Figure 2]. Bone marrow biopsy demonstrated <10% infiltration by lymphoplasmacytic cells with immunopheno-type CD20+, CD5-, and CD23-. [Figure 3] shows the summary of the clinical course. The patient was treated with dexamethasone, cyclophosphamide, rituximab, and bortezomib. Because of increased levels of IgM (peak 4120 mg/dL) with hyperviscosity syndrome (>10.0 centipoise), plasmapheresis was instituted. However, progressive proteinuria and hyper-bilirubinemia were noted. The patient subsequently developed acute kidney injury and complications of hepatic failure. Owing to his massive ascites and altered coagulation profile, liver biopsy was contraindicated. The patient was not considered to be a suitable candidate for liver transplantation due to multiple organ failure. He eventually died of pneumonia, just two months after diagnosis.{Figure 1}{Figure 2}{Figure 3}

 Discussion



We describe a patient initially presenting with nephrotic syndrome related to IgM monoclonal gammopathy in the absence of significant bone marrow lymphoplasmacytic infiltration and other characteristic features of WM that otherwise would be classified as MGRS. However, rapid disease progression to WM was identified when the patient developed hyperviscosity syndrome. To our knowledge, abrupt evolution like our case has never been reported in the literature.

Renal disease related to WM occurs infrequently. The largest series of biopsy-proven WM-related nephropathy in a cohort of 1,391 WM patients was described by Vos et al in 2016.[2] A total of 44 cases were identified. The estimated cumulative incidence of WM-related nephropathy was 5.1% at 15 years from WM diagnosis. There was a wide variation in kidney pathology, including amy-loidosis (25%), monoclonal IgM deposition disease/cryoglobulinemic glomerulonephritis (23%), lymphoplasmacytic lymphoma infiltration (18%), light-chain deposition disease (9%), cast nephropathy (9%), thrombotic microangiopathy (7%), minimal change disease (5%), membranous nephropathy (2%), and crystal-storing tubulopathy (2%).

Hepatic failure is another unique feature of our patient. Although hepatomegaly due to infiltration by lymphoplasmacytic cells is a characteristic feature of WM, it generally is not associated with severe liver damage. We suppose his hepatic failure was related to amyloidosis. Light chain amyloidosis (AL) can complicate IgMMGUS and WM. However, this is an uncommon event. IgM-related AL amyloidosis accounts for 6% of all AL amyloidosis cases and was reported in 2% of patients with IgM monoclonal gammopathy. Hepatic involvement is present in 62–90% of all AL amyloidosis cases and was reported in 14%–26% of IgM-related AL amyloidosis patients.[3] Despite the high prevalence of hepatic involvement with AL amyloidosis, clinical manifestations are generally mild. The development of acute hepatic failure from this entity is rare. Norero et al have previously published a review identifying 10 cases of acute hepatic failure associated with AL amyloidosis.[4] In all of these cases, patients initially presented with nonspecific symptoms such as jaundice, anasarca, or weight loss and subsequently developed fulminant hepatic failure over two to nine weeks from the time of initial presentation.

The therapeutic options for WM depend on the rapidity with which the symptom control is necessary. Hyperviscosity-related symptoms warrant urgent plasmapheresis. Rituximab (anti-CD20 monoclonal antibody)-based therapy is a preferred treatment option for most patients with symptomatic WM. Rituximab is generally well tolerated. However, rituximab alone is a poor choice for patients in urgent need of therapy since its median time to response is long, around three to four months or more.[5] In addition, a unique complication of rituximab therapy in WM is the IgM flare phenomenon. Bortezomib (proteasome inhibitors) is among the most effective therapies in WM, particularly when combined with steroids and rituximab, with a median time to response of 1.4 months.[6] The rapid response prompts physicians to use this combination in patients with hyperviscosity syndrome. Neuro-toxicity is the major concern with the use of bortezomib, and underlying IgM-related neuropathy may further complicate its use.

 Conclusion



Our case suggests that the evolution of IgMMGRS to WM could be abrupt. Disease activity should be monitored carefully. The prognosis of these patients with rapid disease progression is grave without prompt and effective chemotherapy. Since mortality usually arises from organ failure, evaluation of organ replacement therapy should be initiated promptly. Furthermore, new therapeutic approaches targeting amyloid deposit have to be developed in order to improve organ response.
