Regularities of cytokine status changes in chronic lymphocytic leukaemia and their role in pathogenesis of progressive forms of disease

Abstract

The aim of the research is to study and to analyze results of investigations of cytokine blood profile in patients with B-cellular chronic lymphocytic leukaemia. Materials and methods: Complex investigation of 60 patients with B-cellular chronic lymphocytic leukaemia has been carried out. Patients have been randomized into 4 groups of observation according to the severety of disease (classification of Rai K. R., 1975). Accepted methods of somatic status and he-matologic indices as well as method of flow cytometry for establishment of B-lymphocytes immune phenotype have been used. Cytokine levels were detected by enzyme immunodetection. Results: Regular peculiarity of cytokine status change in different forms of chronic lymphocytic leukaemia development has been an increase of interleukine-4, interleukine-6, interleukine-7, interleukine-10 and tumor necrosis factor-alpha levels in serum that is one of the main pathogenetic factor of intercellular interaction abnormality in lymphoid tissue in the chronic lymphocytic leukaemia development. Conclusion: Increased indications of cytokines content in blood may be used as diagnostic criteria of pathology severity and in evaluation of effectiveness of complex therapy of the disease, as well as a classification sign of severity of chronic lymphocytic leukaemia
