MONOCLONAL GAMMOPATHY. Monoclonal means a single clone/copy of a plasma cell. Gammopathy stands for gammaglobulin, another name for antibody or protein. So monoclonal gammopathy is the presence in the blood of a large quantity of one antibody/protein - or paraprotein. The excess protein may be detected as part of any complete physical examination, through a process known as serum protein electropheresis performed on a blood sample. Neurologists are aware that there may be anti-nerve components in the protein that, in certain circumstances, may recognise components on the myelin or axon and react. Thus damage to the myelin and/or the axon of peripheral nerve cells occurs. Most people with a paraprotein in their serum will be unaware of its presence however. It may exist benignly for years without the bearer having any awareness of it or any symptoms of damage ever occurring. Yet some 3% of people with a paraprotein or monoclonal gammopathy may acquire a neuropathy.

POSSIBLE DISORDERS from a monoclonal gammopathy. A number of disorders termed paraproteinaemic neuropathies, closely connected with the presence of paraprotein/monoclonal gammopathy, do occur. Peripheral neuropathy (disorder of the peripheral nerves) in association with a monoclonal gammopathy (paraprotein) is not totally uncommon. One group of neurological researchers (Kelly et al) found a paraprotein in 10% of people with otherwise undiagnosed peripheral neuropathies. Systemic diseases such as diabetes mellitus, alcoholism and connective tissue disorders may have been eliminated at an early diagnostic stage.

Most monoclonal gammopathies are non-malignant but when paraprotein is found in the serum along with a neuropathy, then there should be tests for any suspected, potentially serious malignant conditions, in order to exclude them from the diagnosis. These disorders include multiple myeloma, amyloidosis (AL), lymphoma, POEMS syndrome (osteosclerotic myeloma), leukemia and Waldenström's Macroglobulemia. However in 2-3rds of patients with paraprotein and a neuropathy no underlying malignant disorder is found to explain the presence of the monoclonal gammopathy/paraprotein.

MGUS - monoclonal gammopathy of undetermined significance, is then the diagnosis by elimination. There is a smaller amount of paraprotein in the serum of MGUS bearers than in the serum of those with the malignant disorders. Patients with MGUS usually have less than 15% marrow plasma cells; a serum monoclonal protein level less than 3 g/dL. In IgM it is usually <2.5g/dl, in IgA <1.5g/dl and in IgG <2.5g/dl. Also the levels of the other immunoglobulins are within the normal reference range, there is no urinary Bence-Jones protein, and no anemia, renal failure, lytic bone lesions or hypercalcemia. NOTE. The term 'undetermined significance' may be ultimately misleading. It has been assessed that 17% to 25% of MGUS bearers may develop one of the malignant disorders, usually in another ten years.

BY DEDUCTION, if there is an unexplained underlying neuropathy with the MGUS/paraprotein, then the probable remaining form of paraprotein-related polyneuropathy is one of the Paraproteinaemic Demyelinating Neuropathy group – be it IgM, IgG or IgA. These are explained on the next page!

ANNUAL TESTS RE POTENTIAL MALIGNANCY. The level of paraprotein in the blood of every PDN sufferer should be checked at least annually and indefinitely. This is to check for any significant rise in the level that would indicate the developing presence of a more serious malignant condition. However, in a long-term clinical and neurophysiological follow-up of 50 patients "with peripheral neuropathy associated with benign monoclonal gammopathy", that is PDN, only three patients developed haematological malignancy. (Sawantha Ponsford et al. 2000.)



Go on you for posting it again. Sometimes things just get missed. Keep hitting us over the head and sooner or later someone notices.

I don't know anything about this but I love new info so thank you for taking the time and effort to share. I shall enjoy reading.
So from reading I understand that paraprotein needs to be checked regularly in case it leads to malignancy?

What symptoms do you experience with it?
Do you think it connects with your RA?
How does it effect your RA?
What do they treat it with?


hi cordelia nice to meet you.. i have a lot of stangethings goingon in the body
i knew i had paraprotein 13 yrs ago..but never knew what it was . then got internet
and done some searching.. i am more interested to learn if any 1 whith paraprotein
is getting the neuropathy .. i get yearly tests ..there is no treatment.. unless
paraprotein levels rise i have copied this below tohelp youa little more..
i have been moitored for 5yrs for chronic leukemia but this was due to high white count
and fevers. wbc has been high scince having ra.. but haematologist is 99.9 percent
sure wbc and fevers aredue to severe ra and pred usage..

Summary  There is evidence that the prevalence of monoclonal parparoteinaemia is slightly increased in patients with rheumatoid arthritis. The possibility that this may be a marker of the development of later malignancy in such patients is explored. Mortality rates in rheumatoid arthritis are increased although the development of lymphoreticular malignancy contributes only a small percentage of this increase. However, it does seem likely that patients with longstanding severe rheumatoid arthritis are more at risk of developing myeloma or lymphoma if they have a monoclonal paraprotein band in their serum. IgA paraprotein seems to carry a higher risk than IgG whilst other factors such as urinary free light chains and the presence of secondary Sjögren's syndrome are of less prognostic significance. Similarly a monoclonal para-protein may identify patients with primary Sjögren's syndrome who have a particular risk of later lymphoma whilst this risk does not appear to extend to patients with systemic lupus erythematosus. Patients with an overlap syndrome do not appear to be at greater risk than those with “pure disease”. The association of other rheumatological disease and paraproteinaemia is briefly discussed.
Wow, Boney. Nice to meet you too. I am an 'oldie' here but in the last month or so hadn't been posting much.

Thank you for all that info. I hope someone else knows something about it and can help you.

Your poor old body is going through a lot, by the sounds of it. Many of us are having to deal with multiple issues of varying proportions. I so hope you find your way though. I noticed your sense of humor is well in tact which is always beneficial for getting through challenges. I try and keep mine well oiled also.

ok cordelia ..well i tryto keep postive and it helps to have a laugh..
and a good sense of humoure can certainly help.. i hope you got a large can
of oil you may need it
