What is a monoclonal spike?
A monoclonal spike (M spike or paraprotein) on serum protein electrophoresis (SPEP) is a frequent finding in the general population and typically is pathognomonic of an asymptomatic, premalignant condition called monoclonal gammopathy of undetermined significance (MGUS).
How serious is M spike?
Most people who have M proteins in their blood don’t go on to develop further health problems. However, a small number of people with MGUS will develop serious cancers or conditions of the blood, such as multiple myeloma.
What does it mean when your M spike is high?
High levels of M proteins can indicate that a person has multiple myeloma. However, high M protein levels may also be a sign of several other plasma cell disorders, including: solitary plasmacytoma. smoldering multiple myeloma (SMM)
Is M protein the same as M spike?
If the substance shows up in your blood or urine, it’s a sign you might have that disease or another condition. M proteins go by a lot of different names. You may hear your doctor call them “monoclonal ” proteins. They’re also called monoclonal immunoglobulin, mylenoma, M spike, or paraprotein.
What is considered a high level of M protein?
High levels mean the disease is more advanced and may indicate a poor prognosis. The presence of any M spike is abnormal and shows the presence of an abnormal clone of plasma cells. If the amount of protein is ≥30 g/L and/or there are other disease symptoms, the patient may have myeloma.
Can M spike fluctuate?
The M-spike usually remains stable with small fluctuations in its concentration, until MM develops. Patients are at higher risk for developing venous thromboembolism, osteoporosis, and fractures, even in the absence of progression to MM.
Can you live a long life with MGUS?
Data from the Mayo Clinic showed that the median survival of MGUS patients was 8.1 years compared to 11.8 in the comparable US population. In a prior study from Denmark, 1,324 MGUS patients were found to have a 2-fold higher mortality compared to that of the general population.
Who is most likely to get multiple myeloma?
Myeloma occurs most commonly in people over 60. The average age at diagnosis is 70. Only 2% of cases occur in people under 40.
Is multiple myeloma a painful death?
Experiencing a Peaceful Passing Accounts of those who have accompanied a loved one as they died from complications of multiple myeloma generally report a relatively calm death in which pain has been effectively managed.
What causes an M spike?
Many conditions can cause a monoclonal gammopathy, a spike in one protein product; and, not all of these conditions are cancerous. You can have M protein with certain connective tissue disorders, like systemic lupus erythematosus, rheumatoid arthritis, and psoriatic arthritis.
What causes M protein Spike?
In contrast, polyclonal gammopathies may be caused by any reactive or inflammatory process, and they usually are associated with nonmalignant conditions. An M protein is characterized by the presence of a sharp, well-defined band with a single heavy chain and a similar band with a kappa or lambda light chain.
What does elevated M protein mean?
High blood protein may be caused by something as simple as mild dehydration, increasing the concentration of protein in your bloodstream. In this case, the blood proteins only appear to be elevated. High blood protein may also be a warning sign of chronic inflammation or infection, particularly of the liver.
What is it to be a spike?
A spike is a product development method originating from Extreme Programming that uses the simplest possible program to explore potential solutions. It is used to determine how much work will be required to solve or work around a software issue.
