[Immunological and rheological disorders in multiple myeloma patients]

Overall 30 patients with multiple myeloma (MM) were examined for immunological and rheological parameters. MM was shown to be marked by imbalance of immunobiological reactivity, with the greatest changes being seen in the B cell immunity system. MM is also characterized by marked rheological shifts related to the immunological alterations and underlying the hyperviscosity syndrome and heart failure. Administration of polychemotherapy resulted in a decrease of the count of B lymphocytes, circulating immune complexes; a tendency toward normalization of the rheological blood properties was observed. Introduction of plasmapheresis into the treatment program of the patients noticeably raised the treatment efficacy.
