The World

: Hepatitis B virus [HBV], the best-described hepadnavirus, distributed all around the world and may lead to chronic and acute liver disease, cirrhosis, and hepatocellular carcinoma. Despite the advancement in treatment against HBV, an error-prone reverse transcriptase which is require for HBV replication as well as host immune pressure lead to constant evolution and emergence of genotypes, sub-genotypes and mutant viruses; so, HBV will be remained as a major healthcare problem around the world. This review article mainly focuses on the HBV mutations which correlated to occult HBV infection, Immune scape, vaccine failure and eventually liver cirrhosis and HCC. Current study indicated that preS/S region mutations are related to vaccine failure, immune escape, occult HBV infection and the occurrence of HCC. Whereas, P region Mutations may lead to drug resistance to NA antivirals. PreC/C region mutations are associated to HBeAg negativity, immune escape, and persistent hepatitis. Moreover, X region Mutations play an important role in HCC development.

<b><i>Background:</i></b> Although transmission of pathogenic viruses through human tissue grafts is rare, it is still one of the most serious dreaded risks of transplantation. Therefore, in addition to the detailed medical and social history, a comprehensive serologic and molecular screening of the tissue donors for relevant viral markers for human immunodeficiency virus (HIV), hepatitis B virus (HBV), and hepatitis C virus (HCV) is necessary. In the case of reactive results in particular, clear decisions regarding follow-up testing and the criteria for tissue release must be made. <b><i>Methods:</i></b> Based on the clinical relevance of the specific virus markers, the sensitivity of the serological and molecular biological methods used and the application of inactivation methods, algorithms for tissue release are suggested. <b><i>Results:</i></b> Compliance with the preanalytical requirements and assessment of a possible hemodilution are mandatory requirements before testing the blood samples. While HIV testing follows defined algorithms, the procedures for HBV and HCV diagnostics are under discussion. Screening and decisions for HBV are often not as simple, e.g., due to cases of occult HBV infection, false-positive anti-HBc results, or early window period positive HBV NAT results. In the case of HCV diagnostics, modern therapies with direct-acting antivirals, which are often associated with successful treatment of the infection, should be included in the decision. <b><i>Conclusion:</i></b> In HBV and HCV testing, a high-sensitivity virus genome test should play a central role in diagnostics, especially in the case of equivocal serology, and it should be the basis for the decision to release the tissue. The proposed test algorithms and decisions are also based on current European recommendations and standards for safety and quality assurance in tissue and cell banking.

e15199 Background: Occult hepatitis B virus (HBV) infection is characterized by persistence of HBV DNA into the tissue of hepatitis B surface antigen-negative individuals. The clinical relevance of this infection is still under debate. In particular, the impact of occult HBV infection in cases of hepatocellular carcinoma (HCC) is uncertain. Methods: We investigated the prevalence of occult HBV in patients with chronic liver disease, with or without HCC, that were submitted to liver transplantation or partial hepatectomy in Alfa Institute of Gastroenterology from Clinical Hospital - UFMG - Brazil. We tested the presence of VHB DNA in liver sample using nested PCR in four different regions of viral genome (pre-S/S, pre –core/core, polymerase and X). We also tested these patients’serum for HVB antigens (HBsAg and HBeAg)and antibodies (anti-HBs, anti-HBe and anti-HBC). Results: Our studied population included 71 patients, 50 (70.4%) were male and had median age of 51±12.5 years. Cirrhosis etiology was alcoholic (22 cases, 32.4%), viral hepatitis (17 cases, 25%), cryptogenic (16 cases, 23.5%), autoimmune (10 cases, 14.7%) and 3 cases of other etiologies. HCC was found in 22 patients (31.4%). Viral DNA was detected in 4 cases (5.6%), three of them with HCC. Among these three cases viral DNA was found in non-tumoral area in two of them and in HCC sample in the other one. Conclusions: The prevalence of occult hepatitis B infection was high in our population of cirrhotic patients submitted to liver transplant, especially with associated HCC.
