OBJECTIVE: Experimental study of the effect profile of bortezomib in the plasma cell myeloma (PCM) patients depend- ing on a specific phenotype carrier state and a pharmacochemical characteristics of ABO system glycoproteins.
MATERIALS AND METHODS: The research was conducted on the 104 PCM patients, including the Chornobyl NPP acci- dent survivors (n = 49) and 65 study subjects in the comparison group. Immunogenetic criteria for positive response to the applied treatment protocols were issued according to the duration of remission, absence of infectious com- plications, and evidence of chronic renal failure as a disease complication.
RESULTS: Possibility of glycoproteins A and B participation in the formation of human biological individuality at a level of protein-protein interaction with antineoplastic drug bortezomib, which is widely used in cancer management prac- tice, in particular in the PCM treatment is considered. The glycoprotein B was shown being a selective target for borte- zomib, slowing down the recognition and interaction of antigen B with monoclonal anti-B antibody, while the agglu- tination period lengthens at that by 66 %. Assumption that the formation of bortezomib complex with glycoprotein B provides a background for interaction with the key reaction of proteasome 26S inhibition, which to some extent con- tributes to the drug effect retardation was confirmed through the quantum-chemical calculations. Equilibrium is shift- ed toward the main reaction leading to a higher drug efficacy in patients with blood groups O (I) and A (II).
CONCLUSIONS: Since the complexation occurs predominantly in alkaline medium the administration of drugs with alkaline reaction should be restricted for at least round the clock after administration of bortezomib according to its half-life in plasma in patients with B (III) blood group and chronic renal failure.
