ABSTRACT
POEMS syndrome: Heavy Light Chains vs Free Light Chains measurements
POEMS syndrome is a rare paraneoplastic, multisystemic, plasma cell discrasia characterized by Polyneuropathy, Organomegaly, Endocrinopathy, Monoclonal gammopathy and Skin changes. Most patients have high serum free light chains (sFLC) concentrations but a normal sFLC ratio. Hevylite (HLC) is a new method that allows separated quantification of the serum k and l bounded levels of the six isotype specific immunoglobulins. In this study HLC and sFLC were measured in serum samples during the follow up of two patients with POEMS syndrome. The HLC ratio of the involved monoclonal immunoglobulin could provide additional information to assess residual disease, allowing detection of relapse earlier than clinical symptoms in patients with POEMS syndrome.
