Oncology. Monoclonal gammopathy, also known as paraproteinemia, is the presence of excessive amounts of myeloma protein or monoclonal gamma globulin in the blood. It is usually due to an underlying immunoproliferative disorder or hematologic neoplasms, especially multiple myeloma. It is sometimes considered equivalent to plasma cell dyscrasia.
A small spike would be present in the gamma (γ) band in MGUS. Monoclonal gammopathy of undetermined significance ( MGUS) is a plasma cell dyscrasia in which plasma cells or other types of antibody-producing cells secrete a myeloma protein, i.e. an abnormal antibody, into the blood; this abnormal protein is usually found during standard ...
Monoclonal gammopathy of renal significance. Monoclonal gammopathy of renal significance ( MGRS) are a group of kidney disorders that present with kidney damage due to nephrotoxic monoclonal immunoglobulins (M proteins) secreted by clonal plasma cells or B cells. By definition, people with MGRS do not meet criteria for multiple myeloma or other ...
In hematology, plasma cell dyscrasias (also termed plasma cell disorders and plasma cell proliferative diseases) are a spectrum of progressively more severe monoclonal gammopathies in which a clone or multiple clones of pre-malignant or malignant plasma cells (sometimes in association with lymphoplasmacytoid cells or B lymphocytes) over-produce and secrete into the blood stream a myeloma ...
Being asymptomatic, monoclonal gammopathy of undetermined significance and smoldering multiple myeloma are typically diagnosed fortuitously by detecting a myeloma protein on serum protein electrophoresis tests done for other purposes. MGUS is a relatively stable condition afflicting 3% of people aged 50 and 5% of people aged 70; it progresses ...
Bortezomib-based management, Organ transplant. Monoclonal immunoglobulin deposition disease, or MIDD, is a disease characterised by the deposition of monoclonal immunoglobulins on the basement membrane of the kidney. Monoclonal immunoglobulins are produced by monoclonal plasma cells, which are found in a variety of plasma cell dyscrasias.
Plasma cell dyscrasia. Plasma cell dyscrasias are a group of monoclonal gammopathies in which normal plasma cells in the bone marrow and soft tissues become altered. POEMS syndrome is often associated with an IgA or IgG lambda limited plasma cell dysfunction. On iliac crest biopsies, patients with POEMS syndrome often have few monoclonal plasma ...
Smouldering myeloma is a disease classified as intermediate in a spectrum of step-wise progressive diseases termed plasma cell dyscrasias.In this spectrum of diseases, a clone of plasma cells secreting monoclonal paraprotein (also termed myeloma protein or M protein) causes the relatively benign disease of monoclonal gammopathy of undetermined significance.
