5th to 6th decade of life. [6] Duration: Chronic. [6] ... Takatsuki disease, or PEP syndrome) is a rare paraneoplastic syndrome caused by a clone of aberrant plasma ...
Multiple myeloma is the result of a multi-step malignant transformation, and almost universally originates from the pre-malignant stage monoclonal gammopathy of undetermined significance (MGUS). As MGUS evolves into MM, another pre-stage of the disease is reached, known as smoldering myeloma (SMM). [15]
MGUS is a common, age-related medical condition characterized by an accumulation of bone marrow plasma cells derived from a single abnormal clone. Patients may be diagnosed with MGUS if they fulfill the following four criteria: [7] A monoclonal paraprotein band less than 30 g/L (< 3g/dL); Plasma cells less than 10% on bone marrow examination;
In another study, MGUS patients with none, 1, or 2 of the following risk factors, >95% of bone marrow plasma cells that are clonal in nature and a 10% or greater rise in the levels of their monoclonal proteins within 3 years, had 2, 16, and 72% risks, respectively, of progression within 7 years.

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.
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.
Importantly, they found that life expectancy for adults with ADHD relative to the general population was: 8.64 years shorter for females 6.78 years shorter for males.
The prevalence and incidence of MGRS in the general population or in specific populations is not known but it is more prevalent in those over the age of 50 as there is a monoclonal protein (M-protein) present in 3% of those 50 and years older and 5% of those 70 years and older (the presence of MGUS), placing those 50 and older at increased risk ...
