response to various treatments in the patients with chronic hepatitis b; a cross-sectional study

Hepatitis b is one of the most common chronic viral infections worldwide, especially in developing countries. the insufficient treatment of the disease increases the risk of cirrhosis and hepatocellular carcinoma, which impose heavy costs to the patient and the society. different studies evaluated several protocols for the treatment of the disease. the aim of this study was to evaluate the response rate of the different treatments in patients with chronic hepatitis b (chb). in a cross-sectional study, 89 patients with chb who were referred to infectious diseases clinics during 2004 to 2009 were studied. serological and biochemical outcomes to the different treatments were evaluated. the data were analyzed by spss 16. chb was more frequent in men (74.2%) than women (25.8%). the mean age of the patients was 36 ± 1.36 years. fifty-three patients (59.6%) had active chb while 36 (40.4%) were asymptomatic carriers. serologic and biochemical responses to the treatment were 50% and 69.44%, respectively. however, 50% of the patients with positive hbeag showed serologic response to the treatment, 37.5% showed hbeab as well as reduced amounts of hbeag, and 12.5% just showed reduced amounts of hbeag. patients treated by lamivudine showed the highest serologic response rate (75%). serologic and biochemical response to the different treatments in the patients were better than other similar studies. besides, it is recommended to begin antiviral therapy against chb infection with lamivudine alone as a first-line therapy.
