Objective To explore the clinical efficacy of entecavir combined with Vitamin E in treating patients with Chronic hepatitis B complicated with non-alcoholic fatty liver.Methods Retrospective analysis was done by reviewing the clinical data of 103 patients, who suffered with chronic hepatitis B complicated with non-alcoholic fatty liver and treated in our hospital from 2015 to 2016.The patients were divided into the control group with 61 cases and the observation group with 42 cases based on different therapies.The control group was treated with only entecavir while the observation group was treated with entecavir and Vitamin E, and both the courses of treatment lasted for 6 months.The negative conversion ratio of HBV-DNA, levels of ALT, TBIL, ALP, the disease state and the adverse reactions of the two groups were compared before and after treatment.Results The negative conversion ratio of HBV-DNA of the observation group was obviously higher than that of the control group, and the patients of the observation group showed significant improvement.Meanwhile, the levels of ALT, TBIL and ALP in the two groups were both lower than before treatment.Compared with the control group, those indexes in the observation group were significantly lower (P<0.05).Conclusion Entecavir combined with Vitamin E for the treatment of chronic hepatitis B complicated with non-alcoholic fatty liver could significantly decrease the viral infections so that the state of patients can be improved.
