Abstrakt: Objective: identify the nature of anti-inflammatory and pro-inflammatory cytokine regulation in different periods of plasma cell myeloma (PCM) natural history with evaluation of its role as a prognostic criterion for the disease course in the Chornobyl NPP (ChNPP) accident survivors. Materials and methods. Levels of pro-inflammatory (IL-6, TNF-α) and anti-inflammatory (IL-10) cytokines both with their relationship were studied in the stage I-II and stage III PCM patients (n = 74) in different periods of the disease natural history i.e. remission/stabilization and progression. Study groups included the ChNPP accident survivors (n = 35) and non-irradiated subjects (n = 39). Immunoenzymatic method was applied using the Vector-Best CJSC commercial kits. Results. There was a unidirectional increase in the levels of IL-6, TNF-α, and IL-10 in irradiated persons, and an elevation of IL-6 and TNF-α; concentration but with a decreased level of IL-10 in non-irradiated subjects compared to control at the time of PCM diagnosis. Period of the disease remission/stabilization in PCM stage I-II patients featured a decrease in IL-6 concentration regardless of the exposure to ionizing radiation, while TNF-α content remained at the level of the control group. There was a significant increase in IL-6 concentration in both study groups during the disease relapse, while TNF-α level remained unchanged compared to stabilization phase of the disease. According to the obtained data a certain contribution of radiation exposure to the PCM pathogenesis as a possible predictor of the exacerbated disease course cannon be excluded. Conclusion. Determining the serum level of pro-inflammatory and anti-inflammatory cytokines (IL-6, TNF-α and IL-10 respectively) provides advancement in assessment of the PCM course and predict the effectiveness of administration of therapy protocols.
