Curative effect of interferon in the treatment of chronic hepatitis / 中国基层医药

ABSTRACT

Objective To investigate the effect of recombinant interferon in the treatment of chronic hepatitis and the influence of neutralizing antibody (NA) on its clinical efficacy.Methods 80 cases with chronic hepatitis were randomly divided into the treatment group(n=40) and control group(n=40).The content of HBV DNA was determined by fluorescence quantitative polymerase chain reaction ( PCR) assay.The neutralizing antibodies against interferon were measured by antiviral-neutralizing assay(AVA).Results After the treatment,the content of HBV DNA in the observation group was significantly lower than before treatment (F=12.55,P0.05).The contents of HBV DNA in NA positive group had no significant difference before and after treatment (F=0.88,P>0.05);The contents of HBV DNA in NA negative group had significant difference before and after the treatment ( F=11.55,P<0.05).In 80 cases,degree of cell lesions in 0 grade(10 cases),1 grade(25 cases),2 grade (25 cases),3 grade (12 cases) and 4 grade(8 cases).Conclusion The recombinant interferon in the treatment of chronic hepatitis has certain effect,but NA can affect its treatment effect .
