We report the case of a male,33-year-old cirrhotic patient who has tested positive for serum HBsAg,and HBeAg,with 9.04 × 107 copies/mL of HBV DNA. He suffered from acute liver failure and was near death before undergoing emergency LT. No HBIg was available at the time,so only lamivudine was used. He routinely received immunosuppression medication. Serum HBV DNA and HBsAg still showed positive post-LT,and the graft re-infected. Hepatitis B flared three months later. Adefovir dipivoxil was added to the treatment,but in the 24th mo of treatment,the patient developed lamivudine resistance and a worsening of the hepatitis occurred shortly thereafter. The treatment combination was then changed to a double dosage of entecavir and the disease was gradually resolved. After 60-mo of post-LT nucleos(t)ide analogue therapy,anti-HBs seroconverted,and the antiviral was stopped. By the end of a 12-mo follow-up,the patient had achieved sustained recovery. In conclusion,the case seems to point to evidence that more potent and less resistant analogues like entecavir might fully replace HBIg as an HBV prophylaxis and treatment regimen.展开更多

In men, it is the fifth most common cancer and seventh most common in women;HCC is the second highest cause of cancer-related death worldwide. It is less prevalent in the USA and Northern Europe and more prevalent in Eastern and South-Eastern Asia. Over 700,000 cases are diagnosed each year - half of which occur in China - and result in roughly the same number of deaths per year. HCC significantly impairs quality of life and is associated with great costs to society. It is estimated that half of the deaths from HCC are associated with hepatitis B virus (HBV). Fortunately, HBV vaccination and antiviral therapy have shown excellent efficacy in decreasing the incidence of HCC. We will discuss the relationship of HBV to HCC, address available treatments for HBV and the impact of treatment on the development of HCC.展开更多
