Spontaneous resolution of de novo hepatitis B after living donor liver transplantation with hepatitis B core antibody positive graft: a case report

Feasibility of using marginal liver grafts in living donor liver transplantation

Liver transplantation (LT) is one of the most effective treatments for end-stage liver disease caused by related risk factors when liver resection is contraindicated. Additionally, despite the decrease in the prevalence of hepatitis B virus (HBV) over the past two decades, the absolute number of HBsAg-positive people has increased, leading to an increase in HBV-related liver cirrhosis and hepatocellular carcinoma. Consequently, a large demand exists for LT. While the wait time for patients on the donor list is, to some degree, shorter due to the development of living donor liver transplantation (LDLT), there is still a shortage of liver grafts. Furthermore, recipients often suffer from emergent conditions, such as liver dysfunction or even hepatic encephalopathy, which can lead to a limited choice in grafts. To expand the pool of available liver grafts, one option is the use of organs that were previously considered “unusable” by many, which are often labeled “marginal” organs. Many previous studies have reported on the possibilities of using marginal grafts in orthotopic LT; however, there is still a lack of discussion on this topic, especially regarding the feasibility of using marginal grafts in LDLT. Therefore, the present review aimed to summarize the feasibility of using marginal liver grafts for LDLT and discuss the possibility of expanding the application of these grafts.

Kushenin combined with adefovir dipivoxil affects the HBV-DNA load in serum, immune functions and liver functions of patients with chronic hepatitis B

This study aimed to explore the effect of kushenin combined with adefovir dipivoxil on the load of hepatitis B virus DNA (HBV-DNA) in serum, in immune functions and in liver functions of patients with chronic hepatitis B. A sample of 80 patients with chronic hepatitis B was selected who were admitted to Weifang People's Hospital for treatment between January, 2013 and December, 2015. They were divided into the observation group (n=40) and the control group (n=40). The patients in both groups received adefovir dipivoxil, while those in the observation group additionally received the kushenin. Variations in HBV-DNA load and transforming growth factor-β1 (TGF-β1) in the two groups were detected before intervention, at 1 month, 3 months and 6 months after intervention. In addition, after intervention, we also observed the changes in CD4+, CD8+ and CD4+/CD8+, as well as the levels of immune globulin. Furthermore, in these two groups, we detected the changes in endotoxin in serum before and after intervention, the liver function after intervention, and the variations of hyaluronic acid (HA) and type III procollagen (PCIII) before and after intervention which were used to serve as the indicators for hepatic fibrosis. Results showed that at one month, 3 months and 6 months after intervention, HBV-DNA load and the level of TGF-β1 in the observation group were lower than those in the control group (P<0.05). In the observation group, the HBV-DNA load at 6 months after intervention was the lowest, sequentially followed by the levels at 3 months, at 1 month and before intervention (P<0.05). After intervention, the levels of CD4+ and CD8+ and CD4+/CD8+ in the observation group were higher than those in the control group (P<0.05). Moreover, the levels of immunoglobulin M (IgM), immunoglobulin G (IgG) and immunoglobulin A (IgA) were elevated in the observation group compared to the levels in the control group (P<0.05). Additionally, the level of endotoxin in serum, the levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST) and total bilirubin (TBil). Besides, after intervention, the levels of HA and PCIII in the observation group were found to be lower than those in the control group before and after intervention (P<0.05). This study concludes that, for patients with chronic hepatitis B, kushenin combined with adefovir dipivoxil can remarkably decrease the HBV-DNA load, improve their immunity, ameliorate the liver function and delay the onset of liver cirrhosis.
