Case Rep Oncol 2020 May-Aug;13(2):883-891. Epub 2020 Jul 29.

Department of Medical Education, Hamad Medical Corporation, Doha, Qatar.

Pleural effusion is a rare presentation of plasma cell myeloma, occurring in around 6% of patients during the course of their disease, most commonly as a consequence of a concurrent disease process like heart failure secondary to amyloid deposition. Direct infiltration of the pleural fluid by malignant cells leading to myelomatous pleural effusion is a rare mechanism occurring in less than 1% of patients with plasma cell myeloma, and it is associated with a worse prognosis. There are few case reports of myelomatous pleural effusion as an initial presentation of multiple myeloma. Read More

Extramedullary multiple myeloma with central nervous system and multiorgan involvement: Case report and literature review.

J Radiol Case Rep 2019 Dec 31;13(12):1-12. Epub 2019 Dec 31.

Department of Radiology, Sengkang General Hospital, Singapore.

Multiple myeloma is a hematologic malignancy due to monoclonal plasma cell proliferation. It is usually confined to the bone marrow, although extramedullary involvement is known to occur in almost any organ system; myelomatous spread to the central nervous system is a rare manifestation of myeloma. Extramedullary disease is thought to be related to hematogenous spread when myeloma cells show decreased cell surface receptor expression, allowing cells to escape from the bone marrow. Read More

Mesangiogenic progenitor cells are forced toward the angiogenic fate, in multiple myeloma.

Oncotarget 2019 Nov 26;10(63):6781-6790. Epub 2019 Nov 26.

Department of Clinical and Experimental Medicine, Hematology Division, University of Pisa, Pisa, Italy.

Multiple myeloma (MM) progresses mainly in the bone marrow where the involvement of a specific microenvironment plays a critical role in maintaining plasma cell growth, spread, and survival. In active disease, the switch from a pre-vascular/non-active phase to a vascular phase is coupled with the impairment of bone turnover. Previously, we have isolated (MPCs), a bone marrow population that showed mesengenic and angiogenic potential, both and . Read More

Preventing and Repairing Myeloma Bone Disease by Combining Conventional Antiresorptive Treatment With a Bone Anabolic Agent in Murine Models.

J Bone Miner Res 2019 05 26;34(5):783-796. Epub 2018 Nov 26.

Sheffield Myeloma Research Team, Department of Oncology and Metabolism, Medical School, University of Sheffield, Sheffield, UK.

Multiple myeloma is a plasma cell malignancy, which develops in the bone marrow and frequently leads to severe bone destruction. Current antiresorptive therapies to treat the bone disease do little to repair damaged bone; therefore, new treatment strategies incorporating bone anabolic therapies are urgently required. We hypothesized that combination therapy using the standard of care antiresorptive zoledronic acid (Zol) with a bone anabolic (anti-TGFβ/1D11) would be more effective at treating myeloma-induced bone disease than Zol therapy alone.

Relevance of urinary specific protein assay in the diagnosis of kidney diseases.

Ann Biol Clin (Paris) 2018 Jun;76(3):259-269

Université Paris Descartes, Paris, France, Service de néphrologie, Hôpital Européen Georges Pompidou, Paris, Service de biochimie, Hôpital Européen Gorges Pompidou, AP-HP, Paris, France.

The analysis of urinary protein composition is an important step in the evaluation and monitoring of kidney diseases. Among the various approaches, the determination of urinary-specific proteins makes it possible to non-invasively detect a preferentially tubular or glomerular injury, to orientate towards a pathological process, to guide the indication of a kidney biopsy, and to follow the evolution of the disease and the effectiveness of a therapy. No study systematically evaluated the performance of urinary-specific proteins for the diagnosis of a renal disease. Read More
