The spontaneous seroclearance of hepatitis B upon development of a hepatocellular carcinoma (HCC) is extremely rare. To date, there has been one published case series reporting hepatitis B seroconversion following HCC resection. We describe two novel cases of spontaneous hepatitis B seroclearance following the development of HCC, prior to resection. Following resection, specimens were HBsAg- and HBcAg-negative in both tumor and peritumor tissues. Although the precise mechanism of this is poorly understood, nonuniform integration of hepatitis B virus DNA within the liver could lead to selective tumorigenesis of HBsAg-producing cells, explaining the observed clearance of serum HBsAg with the development of HCC.

Introduction: Despite treatment with antibiotic therapy, spontaneous bacterial peritonitis (SBP) accounts for approximately 20-40% mortality in hospitalized patients. The data is scarce regarding mortality predictors in SBP. Recently, multiple factors have been studied for effectiveness in prognosis prediction in SBP.

This study investigates the impact of twin intrahepatic cholestasis in pregnancy (ICP) in different chorionicity scenarios on pregnancy outcome and risk factors. This retrospective study was designed to investigate the association between ICP and pregnancy outcomes and associated risk factors. Logistic regression analysis was used to verify the correlation between ICP and pregnancy outcome and the associated risk factors with the risk of ICP.

Personalized neoantigen cancer mRNA vaccines are promising candidates for precision medicine. However, the difficulty of identifying neoantigens heavily hinders their broad applicability. This study developed a universal strategy of anti-tumor mRNA vaccine by harnessing "off-the-shelf" immunity to known antigens.

It is estimated that two billion people worldwide are infected with hepatitis B. In such cases, patients exposed to the virus may experience HBV-reactivation(HBVr), which is usually due to immunosuppression. It is not anticipated that spontaneous-HBVr will occur in the absence of immunosuppression in resolved HBV.
