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.
Objective To evaluate the efficacy and safety of antiviral drugs for hepatitis B with YMDD motif variant. Methods We electronically searched MEDLINE (1989-April, 2004), EMBASE (1989-April, 2004), CBMdisc (expand) (1989-April, 2004), and handsearched unpublished Chinese conference proceedings. Randomized and quasi-randomized trials in patients with chronic hepatitis B with YMDD motif variant correlative to lamivudine were collected. Two reviewers extracted the data and assessed the quality of literature independently. The data were then analyzed by RevMan 4.2 software. Results Five studies involving 6 trials and 284 patients were included. According to the results of meta-analysis, antiviral therapy with adefovir plus lamivudine showed significantly better effects on the clearance of serum HBV-DNA and HBeAg and normalization of ALT than that of lamivudine alone (RR 16.61, 95%CI 2.29 to 120.71; RR 6.66, 95%CI 1.23 to 35.88 and RR 6.26, 95%CI 2.29 to 17.12 respectively); also, oxymatrine plus thymothin showed obviously better effects on the clearance of serum HBV-DNA and HBeAg (RR 2.96, 95%CI 1.26 to 6.93 and RR 2.51, 95%CI 1.05 to 5.98 respectively).But adefovir alone showed no better effects on clearance of serum HBV-DNA and HBeAg than that of lamivudine alone (RR 11.00, 95%CI 0.65 to 186.02 and RR 7.00, 95%CI 0.39 to 126.92 respectively); interferon plus lamivudine showed no better effects on the clearance of serum HBV-DNA, HBeAg and the normalization of ALT (RR 3.50, 95%CI 0.90 to 13.58; RR 4.90, 95%CI 0.70 to 35.10 and RR 2.80, 95%CI 0.91 to 8.12 respectively). Chinese herbs plus lamivudine showed no better effects on the clearance of serum HBV-DNA (RR 1.16, 95%CI 0.89 to 1.51). There were no significant side effects in the groups, except flu like symptom in the interferon group, slight kidney impairment in the adefovir group, and aggravation of rare cases in lamivudine group. Conclusions Antiviral therapy with adefovir plus lamivudine, or oxymatrine plus thymothin, shows better effects than with lamivudine alone in terms of antiviral therapy and clinical outcome improvement. However, the evidence is too weak to draw a definite conclusion in this systematic review. Larger sample size and rigorously designed randomized, double blind, placebo control trials are required for future study.
ObjectiveTo summarize the research status of the relationship between hepatitis B virus X protein (HBx), hepatitis B virus (HBV) genotypes and hepatocellular carcinoma (HCC) at home and abroad, and to prospect its clinical significance.MethodThe literatures about HBx, HBV genotypes and HCC were reviewed.ResultsThere was a close relationship between HBx and the occurrence, development, migration and metastasis of HCC. There was a certain association between HBV genotypes and HCC, but the specific mechanism had not been clarified.ConclusionsHBx and HBV genotypes play an important role in the occurrence and development of HCC. With the further study of molecular mechanism, it will promote the diagnosis and treatment of hepatitis B, liver cirrhosis and liver cancer, and provide more individualized intervention for clinical workers.
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.
Objective To assess the efficacy and safety of Chinese medicinal herbs for asymptomatic hepatitis B virus(HBV) infection. Data Source The trials registers of the Cochrane Hepato-Biliary Group, the Cochrane Library and the Cochrane Complementary Medicine Field were searched in combination with MEDLINE, EMBASE, and handsearches of Chinese journals and conference proceedings. Data Selection Randomized clinical trials with 3 months follow-up comparing Chinese medicinal herbs versus placebo, no intervention, non-specific treatment, or interferon treatment for asymptomatic HBV carriers were included. No language and blinding limitations were applied. Data Extraction Data were extracted independently by two reviewers. The methodological quality of trials was assessed by the Jadad-scale plus allocation concealment. Results Three randomized clinical trials (307 patients) with low methodological quality following patients for three months or more after the end of treatment were included. Herbal compound Jianpi Wenshen recipe showed significant effects on clearance of HBV markers compared to interferon: relative risk 2.40 (95 % CI 1.01 to 5.72) for clearance of serum HBsAg, and 2.54 (1.13 to 5.70) for seroconversion of HBeAg to anti-HBe. Phyllanthus amarus and Astragalus membranaceus showed no significant antiviral effect compared with placebo. Analysis of pooling eight randomized clinical trials with less than three months follow-up did not show a significant benefit of Chinese medicinal herbs on viral markers. No serious adverse event was observed. Conclusions There is insufficient evidence for treatment of asymptomatic HBVcarriers using Chinese medicinal herbs due to the low quality of the trials. Further randomized, double blind, placebo-controlled trials are needed.
Objective To explore the relationship between the HBsAg positive patients suffering from hepatocellular carcinoma (HCC) and HBV DNA genotype. Methods By using PCR type-specific primers combined with sequencing of genotype, we analyzed the genotype of HBV DNA in the serum of 500 patients with positive HBsAg in our hospital. Among them, 150 cases suffered from HCC. Results Genotype B and C were both predominant genotypes in HBsAg positive patients. But in HCC group, the rate of genotype C was 65.33% （98/150）, which was significantly higher than that in non-HCC group (88/350, 25.14%), while genotype B, in contrast, was 28.67% （43/150） and 68.86% （241/350）， χ2=75.45， Plt;0.05. The distribution of HBV DNA genotype B or genotype C in different gender or different age groups were not statistically significantly different in cases of HCC (Pgt;0.05). Conclusion Genotype C of HBV DNA is more common in patients with HCC, and maybe there is relationship between genotype C and the occurrence of HCC.
ObjectiveTo investigate the correlation of spontaneous YMDD mutation in different hepatitis B virus (HBV) genotypes with HBV-related hepatocellular carcinoma (HCC). MethodFrom May 2010 to May 2012, 110 HBV-related hepatocellular cancer patients not treated by anti-virus drugs and 1 079 chronic HBV infectors (including asymptomatic HBV carriers, chronic hepatitis B patients, and HBV-related liver cirrhosis patients) were included in our study. HBV YMDD mutation was detected by fluorescence hybridization bioprobe polymerase chain reaction (PCR) and melting curve assay using Diagnosis Kit for HBV YMDD Mutation (Qiagen Biotechnology). Serum HBV genotype was detected by real time PCR using genotype specific TaqMan probe. According to data type, t-test, χ2-test and unconditional logistic regression were used for statistical analysis. ResultsIn the HCC group, genotype C virus, spontaneous YMDD mutation and genotype C virus with YMDD mutation were detected in 39 patients (35.5%), 16 patients (14.5%) and 14 patients (12.7%), respectively. In the chronic HBV infection group, HBV genotype C virus, spontaneous YMDD mutation and genotype C virus with YMDD mutation were detected in 153 patients (14.2%), 46 patients (4.3%) and 17 patients (1.6%), respectively. The difference between the two groups were statistically significant (χ2=33.368, P<0.001; χ2=21.353, P<0.001; χ2=48.889, P<0.001). Unconditional logistic regression analysis suggested that infection of genotype C virus and genotype C virus with spontaneous YMDD mutation might be important risk factors for the development of HCC[OR=2.943, 95%CI (1.778, 4.872), P<0.001; OR=5.989, 95%CI (2.394, 14.980), P<0.001]. ConclusionsInfection of genotype C virus with spontaneous YMDD mutation is tightly related with the occurrence of HCC and has important value for earlier warning of HCC.
目的 探討乙型肝炎病毒（HBV）表面抗原（HBsAg）陽性肝硬化患者血清中HBV前S1抗原(前S1抗原)、HBV e抗原（HBeAg）及HBV核酸定量檢測（HBV DNA）相關性。 方法 2008年7月－2011年5月對97例HBsAg陽性肝硬化住院患者和50份HBsAg陰性的健康體檢者血清進行前S1抗原、HBV血清標志物檢測及實時熒光定量PCR檢測HBV DNA結果進行分析。 結果 97份HBsAg陽性肝硬化患者血清中，前S1抗原、HBeAg及HBV DNA陽性率分別為53.6%（52/97）、22.7%（22/97）及61.8%（60/97）。22例HBeAg陽性血清中，前S1抗原陽性18例（81.8%）， HBV DNA陽性20例（90.9%)。75例HBeAg陰性血清中，前S1抗原陽性34例（45.3%），HBV DNA陽性40例（53.3%），兩者的前S1抗原與HBV DNA結果間都具有很好的相關性。HBV DNA含量與前S1抗原及HBeAg陽性結果顯示：HBsAg陽性的肝硬化患者血清中HBV DNA陰性率為38.1%（含量＜103 copies/mL），而陽性檢出率HBV DNA含量主要集中在103～105 copies/mL，占81.7%（49/60），HBV DNA含量＞105 copies/mL占18.3%（11/60）。 結論 HBsAg陽性的肝硬化患者血清中主要以HBV非HBeAg陽性血清學模式為主，HBV DNA陽性檢出率的含量主要集中在103～105 copies/mL。前S1抗原在HBeAg陽性血清中與其含有HBsAg病毒及HBeAg陽性患者具有很好的相關性，而在HBeAg陰性血清中存在著差異。Objective To study the correlation among Pre-S1 antigen, HBeAg and HBV DNA results in patients with HBsAg-positive liver cirrhosis. Methods We retrospectively analyzed the serum pre-S1-antigen, HBV serum markers and real-time quantitative PCR HBV DNA results in 97 patients with HBsAg-positive liver cirrhosis and 50 HBsAg-negative healthy volunteers in our hospital from July 2008 to May 2011. Results Among the 97 samples of HBsAg-positive liver cirrhosis patients’ serum, the positive rates of Pre-S1 antigen, HBeAg and HBV DNA were 53.6% (52/97), 22.7% (22/97) and 61.8% (60/97), respectively. In the 22 samples of HBeAg-positive serum, the number of positive pre-S1 antigen and HBV DNA was 18 (81.8%) and 20, respectively. In the 75 samples of negative HBeAg serum, the number of positive pre-S1 antigen and HBV DNA was 34 (45.3%) and 40 (53.3%) respectively. The pre-S1 antigen was correlated well with HBV DNA results in both the two groups. HBV DNA level, pre-S1 antigen and HBeAg-positive results showed that the serum HBV DNA negative rate of HBsAg-positive patients with cirrhosis was 38.1% (＜103 copies/mL), while the positive rate of HBV DNA level was mainly concentrated at 103~105 copies/mL, accounting for 81.7% (49/60), and HBV DNA level over 105 copies/mLaccounted for only 18.3% (11/60). Conclusions HBsAg-positive patients with cirrhosis mainly have a serum non-HBeAg-positive HBV serology pattern, and HBV DNA positive rate of the content is mainly concentrated at 103~105 copies/mL. There is a good correlation between pre-S1 antigen in HBeAg-positive serum and patients with HBsAg virus or positive HBeAg, while for Pre-S1 antigen in HBeAg-negative serum, it is quite different.
