RESUMO
The treatment conception was based on the theory of immunocorrective activity function of low doses of human interferon alpha (HuIFN alpha) multi-played by logistic amplifier system included in oral cavity. Twelve patients with chronic hepatitis, HBV infected, aged 7-59, were randomly chosen for treatment. Previously they underwent immunosuppression without success. All of them revealed clinical and biochemical symptoms of steel active disease with morphological progression including active cirrhosis (3 cases). HuIFN alpha therapy was started just after withdrawal of immunosuppression (steroids, steroids and azathioprine). Effects of 50-100 U/d dose of HUIFN alpha were monitored by examination of hematological, biochemical parametres and indicators of humoral and cellular immune response and HBV markers in control liver biopsy specimens too. The HBVDNA serum level was measured besides, using the method of molecular hybridisation. Observation period is from 5 to 17 month, now. Among all patients during 1-2 months from the treatment beginning, transient increase of biochemical parametres of liver function (f. ex: 2-3 times ALAT increase) were observed without any clinical signs of disease exacerbation. All patients revealed immune system activation that lasted longer than incipiens intensive stimulation. Four from twelve patients that finished therapy, eliminated HBVDNA from blood serum. One of them eliminated HBsAg too. Three further confirmed decrease of HBsAg with e system seroconversion. Three from 8 patients treated 6-9 months reveal decrease of HBVDNA concentration in blood serum.
