CONSIDERATIONS FOR INTRADERMAL APPLICATION OF IMMUNIZATION WITH NATIVE AUTOLEUKOCYTES IN MEDICINE.

OBJECTIVE: The aim: Analyzing literature sources, to assess possibilities of using the method of intradermal immunization with native autoleukocytes to treat different diseases, to investigate the areas of usage, efficacy and expediency of the technique in clinical practice. PATIENTS AND METHODS: Materials and methods: Analysis of literature sources associated with intradermal immunization with native autoleukocytes. CONCLUSION: Conclusions: The possibilities of using the method of intradermal immunization with native autoleukocytes in the treatment of various diseases are consid¬ered in the literature review. Intradermal immunization with autoleukocytes is one of the methods of personalized medicine. The application of the method results in normalization of the immune system condition as well as suppression of autoimmune and inflammatory processes. It also reduces the synthesis of pro-inflammatory cytokines and strengthens cellular antiviral immunity in a number of viral infections. It is proved, in particular, that the method reduces the synthesis of cryoglobulins, the formation of antithyroid antibodies, normalizes the level of tumor necrosis factor alpha, as well as reduces extrahepatic manifestations of chronic hepatitis and increases the effectiveness of antiviral therapy in patients with viral hepatitis B. Considering that immunization with native autoleukocytes has no contraindications, it can be used in many diseases.

INTENSIFICATION OF ANTIVIRAL THERAPY OF CHRONIC HEPATITIS B BY MEANS OF INTRADERMAL IMMUNIZATION WITH AUTOLEUKOCYTES.

OBJECTIVE: The aim: Was a trial of intradermal immunization with native autoleukocytes as a curative vaccine. PATIENTS AND METHODS: Materials and methods: Thus, 3-shot series vaccination by means of intradermal injection of autoleukocytes with 30 - 40 days interval was conducted for patients who, in spite of continuous (at least 2 years) therapy with nucleotide analogue, experienced HBV DNA reproduction. For this procedure, 80 - 100 ml of a patient's heparinized venous blood was being precipitated at the temperature 37оС for 120 - 140 minutes, after blood plasma was being centrifuged at 450g for 8 minutes. The precipitate was resuspended in 1 - 1.5 ml of blood serum and injected intradermally in the region of the back. RESULTS: Results: Viral load decreased in all patients even after single immunization; it was possible to achieve a negative result by ultrasensitive PCR method in 23.33% of patients in the group of patients who did not respond adequately to antiviral therapy. CONCLUSION: Conclusions: In patients with chronic hepatitis B, intradermal immunization with autoleukocytes has a significant impact on intensity of virus replication. It is confirmed by a considerable reduction of DNA HBV amount in patients, in whom antiviral therapy was stopped before immunization.

Intensification of antiviral therapy for chronic hepatitis B with autoleukocyte immunization.

INTRODUCTION: The article presents a new method of intensification of antiviral therapy for chronic hepatitis B with intradermal autoleukocyte immunization during treatment with a drug of nucleotide analogues - tenofovir (patent UA 113873 U, 2017); other curative vaccines for chronic hepatitis B are also regarded. OBJECTIVE: The research involves patients with chronic hepatitis B (30), whose replication of HBV DNA decreased to a certain level after long-lasting (over 2 years) antiviral therapy, its further reduction ceased. These patients underwent intradermal autoleukocyte immunization for intensification of antiviral therapy. METHOD: Leukocytes were isolated from plasma of a patient's heparinized venous blood by centrifuging at 400 g for 8 minutes, after that the precipitate was resuspended in 1-1.5 ml of own blood serum and injected intradermally into the back in the dose 0.1 ml. Immunization was conducted at least 3 times with 30-40-day interval. RESULTS: Due to autoleukocyte immunization, the process of further decrease in virus reproduction resumed in 24 patients (out of 30; 80%). Out of six other patients (20%), in whom HBV DNA was detected only by supersensitive PCR method (sensitivity to 5 IU/ml) after long-lasting antiviral therapy, a negative result on examination was achieved in 2 individuals (33.33%). CONCLUSION: Autoleukocyte immunization intensifies efficiency of antiviral therapy for chronic hepatitis B with a drug from the group of nucleotide analogues.
