  • Hi. I see no replies so I just wanted to tell you that I have PBC and have no issues with my gamma or kappa free light chains, no M-spike or other related issues. However, my husband suffers from another, somewhat rare disorder called MGUS, which has caused an elevation in his kappa free light chain and a positive M-spike. Here is an excerpt of the explanation of what MGUS is: Monoclonal gammopathy of undetermined significance (MGUS) is a condition in which an abnormal protein — known as monoclonal protein or M protein — is in your blood. The protein is produced in a type of white blood cell (plasma cells) in your bone marrow. MGUS usually causes no problems but can be a precursor to multiple myeloma and other blood dyscrasias.

    I have not read or heard from our doctors that the MGUS is related to PBC, but then so little is known about what is and isn't a normal cohort of PBC that it's worth asking your gastroenterologist about the free light chain abnormalities.

    Good luck and please post if you find any links to MGUS since I'd be interested in knowing for my husband's sake.
