Objective: Introduction: data about influence of intradermal vaccination with native autoleukocytes on activity level of pro-inflammatory cytokine tumor necrosis factor alpha in patients with chronic hepatitis B have been presented in the article. The aim: Based on positive results, obtained from autoleukocyte immunization in patients with psoriasis [14], the aim of our research was to use and study such therapy for reducing the synthesis of pro-inflammatory cytokine TNF-α in patients with chronic hepatitis B (chronic hepatitis B).

Patients and methods: Materials and methods: Patients with chronic hepatitis B with high level of tumor necrosis factor alpha (≥30pg/ml) were vaccinated with native autoleukocytes (23); simultaneously, the same procedure was performed to patients (11) with low level of this cytokine (5pg/ml). Leukocytes were isolated from heparinized peripheral venous blood of a patient with hepatitis B by centrifuging plasma, obtained after blood precipitation for 140-160 minutes at temperature 370 С. The suspension was resuspended in 1-1.5 ml of a patient's blood serum and injected into the skin of the back in the dose 0.1 ml.

Results: Results: in 30 days after immunization, reduction of tumor necrosis factor alpha was observed in all patients with its high level (100%), in 65.25% of individuals - to 5 pg/ml; in some patients, who had low or average level of pro-inflammatory cytokine, the level individually increased (41.67%).

Conclusion: Conclusions: The elaborated method of influence on activity of tumor necrosis factor alpha in patients with chronic hepatitis B is effective and worth implementing into clinical practice.
