  • Observation of hepatitis B reactivation within 1 month after partial hepatectomy

    Objective To clarify incidence and risk factors of hepatitis B reactivation during short term (one month) in hepatitis B virus (HBV) related hepatocellular carcinoma (HCC) patients receiving partial hepatectomy. Methods From January 2015 to December 2015, 214 consecutive patients with HBV-related HCC who underwent partial hepatectomy were retrospectively enrolled in this study. The risk factors affecting incidence of hepatitis B reactivation were analyzed. Results Hepatitis B reactivation happened in 7.0% (15/214) of patients within 1 month after partial hepatectomy. By univariate analysis, the preoperative HBV-DNA negativity and hepatitis B e antigen (HBeAg) positivity were significantly correlated with the occurrence of hepatitis B reactivation (P=0.023 and P=0.001, respectively). By multivariate analysis, the preoperative HBV-DNA negativity 〔OR=9.21, 95% CI (2.40, 35.45), P=0.001〕 and HBeAg positivity 〔OR=20.51, 95% CI (5.41, 77.73), P<0.001〕 were the independent risk factors for hepatitis B reactivation. Conclusions Hepatitis B reactivation is common after partial hepatectomy for HBV-related HCC during short term, especially in patients whose preoperative HBV-DNA negativity and HBeAg positivity. A close monitoring of HBV-DNA during short term after partial hepatectomy is necessary, once hepatitis B is reactivated, antiviral therapy should be given.

  • Advanced Research of Association of HBV with Spontaneous Rupture of Hepatocellular Carcinoma

    Objective To study the relationship of hepatitis B virus (HBV) to spontaneous rupture of hepatocellular carcinoma (HCC-SR) and its mechanism. Method The related literatures about theory of HCC-SR were consulted and reviewed. Results The injury of small arteries was usually followed in patients with HCC-SR, which was related to vascular autoimmune injury caused by the HBV infection. The small arteries in which immune complex deposited were readily injured, as a result HCC-SR happened while vascular load increased. Conclusion The HBV infection resulted in vascular autoimmune injury maybe a important factor in the pathogenesis of HCC-SR.

  • Research progress of biomarkers of hepatitis B virus and clinical significance

    The infection of Hepatitis B virus (HBV) can result in severe consequences, including chronic hepatitis, liver fibrosis, cirrhosis, and even liver cancer. Effective antiviral treatment has the potential to slow down the progression of the disease. HBV serum biomarkers play a crucial role in the dynamic management of chronic hepatitis B (CHB) patients. However, the conventional hepatitis B virus markers, such as hepatitis B serologic testing and HBV DNA, are insufficient to meet the clinical requirements. This review provided a comprehensive overview of the current research on the quantification of HBsAg and anti-HBc, HBV RNA and HBV core-associated antigen, which summarized the crucial role these markers play in the administration of antiviral medications, predicting the efficacy of treatment and anticipating the likelihood of virologic rebound following drug cessation, as well as assessing disease progression in CHB patients.

  • Clinical Analysis of Lamivudine Combined with Low-Dose Hepatitis B Immune Globulin to Prevent HBV Reinfection after Liver Transplantation

    ObjectiveTo investigate the efficacy of lamivudine combined with low-dose hepatitis B immune globulin to prevent HBV reinfection after liver transplantation. MethodsThe clinical data of 76 cases of HBV-related liver disease after liver transplantation using lamivudine combined with low-dose hepatitis B immune globulin to prevent HBV re-infection were retrospectively analyzed, and the HBV re-infection risk factors were analyzed. ResultsSeventy-six patients' HBsAg became negative after liver transplantation, HBV re-infect in 9 cases.The re-infection rate was 9.2% (7/76) and 11.8% (9/76), respectively, in 1-year and 2-year after liver transplantation. ConclusionsLamivudine combined with low-dose hepatitis B immune globulin after liver transplantation can be effective preventing re-infection with HBV.HBeAg positive and HBV-DNA positive before liver transplantation is risk factors of HBV re-infection.

  • Screening of Hepatitis B Virus Infection before Chemotherapy for Patients with Lymphoma

    ObjectiveTo analyze the influencing factors for hepatitis B virus (HBV) infection screening in lymphoma patients prior to chemotherapy with a focus on HBV reactivation after chemotherapy. MethodsThe HBV infection screening data of 449 patients with lymphoma treated by chemotherapy between June 2010 and July 2012 were analyzed retrospectively. ResultsAmong the 449 patients, 387 (86.2%) were screened for HBV before initiation of chemotherapy, and patients with elevated aminotransferase levels were more likely to receive pre-chemotherapy HBV testing (OR=2.509, P=0.040). HBV reactivation was observed in 16.1% (9/56) of the HBsAg-positive patients after chemotherapy, and it was more likely to occur in patients with the use of rituximab (29.2% vs. 6.3%; P=0.030). Prophylactic antiviral therapy can significantly reduce the incidence of chemotherapy-induced HBV reactivation (12.0% vs. 50.0%; P=0.046). Two cases of reactivation occurred in patients who were HBsAg negative and hepatitis B core antibody positive. ConclusionHBV reactivation, especially for people with the use of rituximab, is a common complication in patients with HBV infection. HBV infection testing should be considered for lymphoma patients who were planned for chemotherapy. Prophylactic antiviral therapy can greatly decrease the incidence of HBV reactivation.

  • Progress on prognosis of hepatitis B virus related acute-on-chronic liver failure with artificial liver support system therapy in emergency department

    Hepatitis B virus related acute-on-chronic liver failure (HBV-ACLF) has the characteristics of rapid progress and high mortality. Artificial liver support system (ALSS) is far superior to standard drug therapy in the treatment of such patients, and is widely used in emergency. ALSS is the use of external mechanical or biological devices to replace a part of the damaged liver function, divided into bioartificial, non-bioartificial liver and a combination of the two. At present, there is no unified sensitive prognostic index and recognized prognostic model for HBV-ACLF in artificial liver treatment. This paper reviews the research progress of prognosis evaluation of ALSS in the treatment of HBV-ACLF, in order to provide reference for clinicians and researchers

  • 荧光定量聚合酶链反应检测法诊断新生儿乙型肝炎病毒感染的卫生经济学评价

    目的 探讨采用荧光定量聚合酶链反应(FQ-PCR)检测法诊断新生儿乙型肝炎病毒(HBV)感染的经济学成本。 方法 对2010年3月-2010年7月间202例日龄在28 d以内的新生儿采用酶联免疫吸附法检测HBV血清学标志物,对于HBV血清学标志物中除乙型肝炎表面抗原外其余任何一项或一项以上阳性的新生儿采用FQ-PCR检测其血清HBV-DNA的含量,并分析确诊1例HBV感染病例的费用。 结果 血清HBV-DNA水平与HBV标志物表现模式有关,乙型肝炎e抗原(HBeAg)阳性的新生儿,FQ-PCR阳性率为3/16 (18.8%)。HBeAg阴性之新生儿,FQ-PCR阳性率为1/186(5.4‰)。HBeAg阳性病例为进一步明确乙型肝炎病毒含量而进行FQ-PCR检测所产生的费用为587元/例,HBeAg阴性者为20 460元/例。 结论 FQ-PCR确诊HBeAg阳性的新生儿为HBV感染的费用-效益比远高于HBeAg阴性的新生儿,对于HBeAg阴性的新生儿该法不适合大规模的流行病学诊断性研究。

  • 微 RNA 在乙型肝炎相关疾病中作用研究进展

    乙型肝炎病毒(hepatitis B virus,HBV)感染是造成肝纤维化、肝衰竭和肝癌的主要原因。微 RNA(microRNA,miRNA)在 HBV 慢性感染状态下出现异常表达。部分表达异常的 miRNA 可以通过活化肝星状细胞或产生胶原蛋白来促进肝纤维化过程;也可以通过诱导肝细胞短期内大量坏死或凋亡来加速肝衰竭进展;亦可以通过上调癌基因或下调抑癌基因表达促进癌症的发生与发展。该文初步探讨了 miRNA 在肝纤维化、肝衰竭、肝癌中的作用。
