Malignancy following solid organ transplant remains a significant threat to the survival of cardiac transplant recipients. Plasma cell dyscrasias including multiple myeloma have been encountered in this population, and medication treatments traditionally used to treat these disorders demonstrate immunomodulatory effects that may have implications on the transplanted allograft. Lenalidomide is an immunomodulatory agent that has been used to treat plasma cell disorders, including light-chain amyloidosis (AL) and multiple myeloma, and represents such a class of medications in which the risks and benefits in the solid organ transplant population remain to be fully elucidated...

BACKGROUND: Plasma cell dyscrasias (PCD) are a spectrum of disorders resulting from the clonal expansion of plasma cells, ranging from the pre-malignant condition monoclonal gammopathy of undetermined significance (MGUS) to multiple myeloma (MM). MM generates a significant burden of disease on the community and it is predicted that it will increase in both incidence and prevalence owing to an ageing population and longer survival secondary to new therapeutic options. Robust and comprehensive clinical data are currently lacking but are required to define current diagnostic, investigational and management patterns in Australia and New Zealand (ANZ) for comparison to both local and international guidelines for standards of care...

AIM: The Danish National Multiple Myeloma Registry (DMMR) is a population-based clinical quality database established in January 2005. The primary aim of the database is to ensure that diagnosis and treatment of plasma cell dyscrasia are of uniform quality throughout the country. Another aim is to support research. Patients are registered with their unique Danish personal identification number, and the combined use of DMMR, other Danish National registries, and the Danish National Cancer Biobank offers a unique platform for population-based translational research...

Plasma cell leukemia (PCL) is a rare, but very aggressive, plasma cell dyscrasia, representing a distinct clinicopathological entity as compared to multiple myeloma (MM), with peculiar biological and clinical features. A hundred times rarer than MM, the disease course is characterized by short remissions and poor survival. PCL is defined by an increased percentage (>20%) and absolute number (>2 × 10(9)/l) of plasma cells in the peripheral blood. PCL is defined as 'primary' when peripheral plasmacytosis is detected at diagnosis, 'secondary' when leukemization occurs in a patient with preexisting MM...

Multiple myeloma (MM) and primary systemic light chain amyloidosis (AL) are both chronic plasma cell dyscrasias with different clinical expression but limited treatment options for relapsed refractory disease. We report the effect of the addition of clarithromycin on 31 MM and 17 AL with relapsed or refractory disease who had an insufficient response or disease progression while on an IMiD based therapy. In this high risk population, hematological response was reported in 48% of MM patients and 94% of AL patients...

Kidney injury related to paraproteinemia is common and typically occurs after the fourth decade of life in association with an underlying plasma cell dyscrasia or other lymphoproliferative disease. Kidney transplantation in paraprotein-related kidney disease can be successful in conjunction with treatment of the underlying hematopoietic process; however, when hematologic response to therapy is not achieved, recurrent kidney injury is frequently seen. We describe a young male patient who presented at the age of 23 years with end-stage kidney disease thought to be secondary to focal segmental glomerulosclerosis; this patient ultimately received two kidney allografts...

Data in the literature are lacking regarding the infection-related adverse events of bendamustine-containing regimens. Therefore, we aimed to assess this risk. We conducted a systematic review and meta-analysis of all randomized controlled trials including bendamustine-containing regimens and those administered for any lymphoproliferative disorder or plasma cell dyscrasia compared with any other regimens. A comprehensive search was conducted until December 2015. Two reviewers appraised the quality of trials and extracted data...

Plasma cell leukemia (PCL) is a rare and aggressive variant of myeloma accounting for 2-3% of all plasma cell dyscrasias characterized by the presence of circulating plasma cells. The diagnosis is based on the % (≥20%) and absolute number (≥2x10 9 /L) of plasma cells in the peripheral blood. The incidence of primary PCL (pPCL) is very rare and reported to occur in <1 in a million. It is classified as either pPCL occurring at diagnosis or as secondary PCL in patients with relapsed/refractory myeloma. pPCL is a distinct clinicopathological entity with different cytogenetic and molecular findings...

BACKGROUND: Serum and urine immunofixation electrophoreses (SIFE/UIFE) are used for clonal detection in plasma cell dyscrasias, while serum free light chain (sFLC) testing provides quantitation of clonal disease. Up to 20% of patients with light chain (AL) amyloidosis may present with normal FLC ratio (FLCr). METHODS: We assessed the diagnostic, quantitative and prognostic potential of serum heavy light chain ratio (HLCr) in 199 untreated patients at initial evaluation...

Systemic AL amyloidosis is known to be associated with plasma cell dyscrasias, including multiple myeloma. The cutaneous manifestations of systemic AL amyloidosis are varied, but typically include waxy plaques or subcutaneous nodules. We report a woman who presented with bilateral eruptions of hyperpigmented plaques in her axillae, which were diagnosed as milia en plaque. She had a history of multiple myeloma, for which she was under the care of a haematologist. This is the first documented case, to our knowledge, of an eruption in the axillae being milia en plaque...

POEMS syndrome is a rare para-neoplastic syndrome secondary to a plasma cell dyscrasia. Effective treatment can control the disease-related symptom complex. We describe the clinical outcome of autologous stem cell transplantation for patients with POEMS syndrome, determining the impact of patient and disease-specific factors on prognosis. 127 patients underwent an autologous stem cell transplantation between 1997-2010 with a median age of 50 years (range 26-69). The median time from diagnosis to ASCT was 7...

Cardiac amyloid light-chain amyloidosis (AL amyloidosis) is a rare disease with a very poor prognosis, associated with plasma cell dyscrasias such as monoclonal gammopathy of undetermined significance and multiple myeloma. Though bortezomib-containing regimens have achieved high hematologic response rates, there are still few reports describing the outcomes of Japanese patients. Six patients with severe cardiac AL amyloidosis were treated with bortezomib-containing regimens. Involved free light chain (iFLC) decreased immediately in most of these cases...

In recent years, the survival of patients with plasma cell dyscrasias has improved due to improvements in anticancer and supportive therapy. However, the risk of secondary malignancies has increased, thought to be due to a combination of environmental and disease-related factors, as well as treatment. In the present review, we evaluate the risk of secondary malignancies in patients with monoclonal gammopathy of undetermined significance (MGUS), multiple myeloma (MM) and Waldenström macroglobulinemia (WM). Patients with MGUS appear to have a higher risk of developing myeloid malignancies such as myelodysplastic syndromes (MDS) and acute myeloid leukemia (AML)...
