Coagulation disturbances in patients with multiple myeloma are presented. Platelet disfunction was especially observed, but only in patients with marked hyperproteinemia and a high level of immunoglobulins in plasma, whereas normal adhesion and aggregation were noticed in 3 out of 17 patients without protein disturbances. Chemotherapy as well as plasma exchange caused not only a decrease of the paraprotein level in plasma, but also a normalization of the failure previously observed in platelet function. Our experiments confirm the opinion that protein M in plasma is responsible for the disturbances observed in multiple myeloma.
