Entecavir and lamivudine therapy for severe acute chronic hepatitis B

Abstract

Severe acute exacerbation in patients with chronic hepatitis B is a unique clinical presentation that results in high mortality. To compare the efficacy of 4 weeks of entecavir or lamivudine therapy in patients with severe acute exacerbation caused by chronic hepatitis B, 65 patients were retrospectively analyzed. The groups received 0.5 mg entecavir (group A) or 100 mg lamivudine (group B) daily. After 4 weeks of treatment, virological and biochemical responses and the deterioration rates were determined. The average age and alanine aminotransferase (ALT), bilirubin, albumin, creatinine (Cr), and HBV DNA levels were similar in groups A and B prior to treatment, but the prothrombin time (PT) was shorter in group A. Following treatment, ALT and bilirubin levels were improved while there were no significant changes in PT, albumin or Cr levels at week 4 in group B. Only ALT was markedly upregulated following treatment in group A. There were no significant differences between the virological and biochemical responses or the deterioration rates of the two groups. These results suggested that short-term treatment with lamivudine markedly alleviated the increased bilirubin (TB) levels in patients with severe acute exacerbation of chronic hepatitis B and that there was no significant difference in the deterioration rate between patients treated by the two types of medication.
