conclusions in our study, only hbv genotype d was found among all the positive hbsag and occult hbv infection. moreover, high prevalence (40.7%) of occult hbv infection was determined among patients suffered from cryptogenic cirrhosis. results eleven (40.7%) out of 27 hbv cryptogenic cirrhosis and all 11 hbsag-positive patients were positive for hbv dna. the seroprevalences of hepatitis b virus...

Human immunodeficiency virus (HIV)- infected patients are at risk of acquiring viral hepatitis, due to common routes of transmission. As the introduction of highly active antiretroviral therapy (HAART) reduced the frequency of opportunistic infections and improved survival, viral hepatitis emerged as an important cause of morbidity and mortality in HIV-infected cases. Occult hepatitis B virus (...

Case series with 1-year follow-up. SETTING. Regional hospital, Hong Kong. PATIENTS. Consecutive patients who were newly diagnosed to have lymphoma in the hospital between 1 April 2007 and 31 March 2008 were tested for hepatitis B...
