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
