Multiple myeloma (MM) is a neoplastic proliferation of plasma cells with overproduction of monoclonal immunoglobulins and infiltration into the bone and other organs. Ascites can develop in patients with lymphoproliferative and solid malignancies involving the peritoneum. However, ascites is unusual in MM and rarely the initial presenting sign or symptom. The development of ascites can be due to peritoneal infiltration or secondary to hepatic involvement, heart failure, or kidney failure. Ascites in MM reflects a more aggressive stage, and the reported prognosis is poor, with a median survival of 1-2 months...

Myeloma cast nephropathy is a major complication of multiple myeloma. Recent evidence has demonstrated that the earlier induction of bortezomib-based chemotherapy with plasma exchange (PE) provides better results for kidney function and patient survival. Due to its non-selectivity, PE with albumin replacement carries the risk of fibrinogen loss, leading to bleeding. We herein report a case of successful treatment of myeloma cast nephropathy using bortezomib-based chemotherapy and selective PE. A 61-year-old woman who had a 20-year history of type II diabetes mellitus was admitted to our hospital for the evaluation of hypercalcemia, severe kidney dysfunction, and anemia...

BACKGROUND AND OBJECTIVES: The exploration of electronic hospital records offers a unique opportunity to describe in-depth the prevalence of conditions associated with diagnoses at an unprecedented level of comprehensiveness. We used a diagnosis-wide approach, adapted from phenome-wide association studies (PheWAS), to perform an exhaustive analysis of all diagnoses associated with hospital-acquired AKI (HA-AKI) in a French urban tertiary academic hospital over a period of 10 years. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: We retrospectively extracted all diagnoses from an i2b2 (Informatics for Integrating Biology and the Bedside) clinical data warehouse for patients who stayed in this hospital between 2006 and 2015 and had at least two plasma creatinine measurements performed during the first week of their stay...

Multiple myeloma (MM) represents a haematological cancer characterized by the pathological hyper proliferation of antibody-producing B-lymphocytes. Patients typically suffer from kidney malfunction and skeletal disorders. In the context of MM, the transforming growth factor β (TGFβ) member Activin A was recently identified as a promoter of both accompanying symptoms. Because studies have shown that bone morphogenetic protein (BMP)-2-mediated activities are counteracted by Activin A, we analysed whether BMP2, which also binds to the Activin A receptors ActRII and ActRIIB but activates the alternative SMAD-1/5/8 pathway, can be used to antagonize Activin A activities, such as in the context of MM...

BACKGROUND: Some malignancies are known to be associated with increased risk of herpes zoster, but little is known about how associations between cancer and subsequent zoster risk vary by cancer site, by time since cancer diagnosis, and by age. METHODS: An age-, sex-, calendar time-, and practice-matched case-control study, nested in the broadly UK representative Clinical Practice Research Datalink (CPRD) primary care database, was analysed using conditional logistic regression to estimate the association between 21 of the most common specific malignancies and subsequent zoster risk...

Two categories of renal disorders associated with monoclonal gammopathies are to be distinguished, according to the characteristics of the underlying B-cell clone. The first group of renal diseases always occurs in the setting of high tumor mass with production of large amounts of monoclonal immunoglobulins. The main complication is the so-called myeloma cast nephropathy, which almost invariably complicates high tumor mass myeloma. The second group includes all renal disorders caused by a monoclonal immunoglobulin secreted by a nonmalignant B-cell clone, and currently referred as a "monoclonal gammopathy of renal significance (MGRS)"...

Multiple myeloma (MM) is a clonal proliferation of malignant plasma cells in the bone marrow (BM) that secretes monoclonal paraproteins in the blood serum and urine. Bone marrow MM cells can invade and damage the functions of other tissues and organs, such as the lungs, spleen, liver, pancreas, kidneys and lymph nodes. However, the invasion of MM cells primarily located in the BM to the anterior mediastinum at the site of the thymus is an extremely rare event. The current study reports the case of a 53-year-old female who presented with MM with involvement of the anterior mediastinum...

Light chain deposition disease (LCDD) is characterized by monotypic immunoglobulin depositions which will eventually lead to loss of organ function if left untreated. While the kidney is almost always affected, the presence and degree of LCDD in other organs vary. Ten to 30% of LCDD patients have underlying Multiple Myeloma (MM), yet outcome and prognostic markers in this particular patient group are still lacking. Here, we analyzed 69 patients with MM and biopsy proven LCDD and report on renal and extra-renal involvement and its impact on prognosis as well as renal response depending on hematologic response...

Transplantation centers have historically considered a history of multiple myeloma as a contraindication to kidney transplantation due to high recurrence rates and poor transplant survival. However, there have been significant advances in the treatment of multiple myeloma, with improved patient survival, which may allow for successful kidney transplantation in these patients. We report on 4 patients who underwent kidney transplantation at our institution between 2009 and 2015 after having achieved a very good partial response or better with chemotherapy and autologous stem cell transplantation...

Immunoglobulin light chain (AL) amyloidosis is a fatal complication of B-cell proliferation secondary to deposition of amyloid fibrils in various organs. Urinary exosomes (UEX) are the smallest of the microvesicles excreted in the urine. Previously, we found UEX of patients with AL amyloidosis contained immunoglobulin light chain (LC) oligomers that patients with multiple myeloma did not have. To further explore the role of the LC oligomers, UEX was isolated from an AL amyloidosis patient with progressive renal disease despite achieving a complete response...

BACKGROUND: Light chain amyloidosis (AL) is a rare deposition disease and is present in 10-15% of patients with myeloma (MM). In contrast to symptomatic AL in MM, presence of bone marrow (BM) amyloid deposits (AD) in MM is not connected to kidney damage. Renal AD but not BM-AD occur mostly in MM with lambda paraprotein (lambda MM). METHODS: We investigated amyloid presence in BM clots taken at diagnosis in 84 patients with symptomatic MM and compared disease characteristics in MM with kappa paraprotein (kappa MM)/lambda MM with and without BM-AD...

Renal impairment (RI) is one of the hallmarks of multiple myeloma (MM) and carries a poor prognosis. Microvesicles (MVs) are membrane vesicles and play an important role in disease progression. Here, we investigated the role of MVs derived from MM cells (MM-MVs) in RI of MM. We found that MM-MVs significantly inhibited viability and induced apoptosis, but not epithelial-mesenchymal transition in human kidney-2 (HK-2), a human renal tubular epithelial cell line. The protein levels of cleaved caspase-3, 8, and 9, and E-cadherin, were increased, but vementin levels were decreased in the HK-2 cells treated with MM-MVs...

Multiple myeloma is characterised by the neoplastic proliferation of a single clone of plasma cells producing a monoclonal immunoglobulin. This clone of plasma cells proliferates in the bone marrow, resulting in extensive skeletal destruction with osteolytic lesions, osteopenia and pathological fractures. Additional disease-related complications include hypercalcaemia, renal insufficiency, anaemia and infection. We present the case of a 64-year-old woman presenting with rapid onset, painful distal symmetrical lower limb weakness and an acute kidney injury...
