Abstract
Paraproteinemic polyneuropathies (PPN) occur generally infrequently and arise from diseases, associated with formation and accumulation of a pathological protein, commonly known as paraprotein, which is typically an immunoglobulin or its free light chain. Such diseases include the following: monoclonal gammopathy of undetermined significance, multiple myeloma, Waldenström’s macroglobulinemia, AL amyloidosis, POEMS syndrome, etc. Diagnosis of PPN is challenging due to nonspecific, indistinct or atypical clinical manifestation, and it is necessary to apply specialized laboratory methods, including immunochemical analysis of blood and urine. Moreover, medications can cause symptoms of polyneuropathy themselves. Thus, it is important to suspect the first symptoms of the disease in time, determine the mechanism of damage to nerve fibers, carry out differential diagnosis and initiate therapy targeting the suppression of pathological protein synthesis.
