  • Clinical characteristics analysis of hepatitis B virus infected individuals with high hepatitis B virus pregenomic RNA

    Objective To analyze the clinical characteristics of individuals with high hepatitis B virus (HBV) pregenomic RNA (pgRNA), and further explore the value of pgRNA in the management of patients with chronic hepatitis B. Methods From December 1st, 2020 to April 1st, 2022, chronic hepatitis B patients who had been treated with nucleotide analogues for a long time and followed up in the Hepatitis Clinic of the Center of Infectious Diseases, West China Hospital, Sichuan University were included, and the clinical characteristics of chronic hepatitis B patients with high pgRNA were analyzed and summarized. Results A total of 107 patients were included. Male patients accounted for 66.4%, with an average age of 44.02 years. There were no statistically significant differences in gender, age, aspartate transaminase, alanine transaminase, γ-glutamyl transferase, HBV surface antigen, proportion of patients with HBV e antigen ≥0.1 U/mL, HBV DNA, and alpha fetoprotein between the high and low pgRNA groups (P>0.05). The proportion of patients with HBV surface antigen<100 U/mL in the high pgRNA group was lower than that in the low pgRNA group (4.4% vs. 22.6%, P<0.05). Conclusion The proportion of chronic hepatitis B patients with high pgRNA whose HBV surface antigen≥100 U/mL is higher.

  • 慢性乙型肝炎患者健康教育需求调查分析

    目的:为了解慢性乙型肝炎患者对乙肝相关知识的了解程度,对健康教育内容和方式的需求,为临床实施健康教育提供依据。方法:采用问卷调查方式,问卷为自行设计,经反复修改,并行预调查,证明可行。发出调查问卷141份,收回113份,回收率80.1%.由专职护士在统一指导语下先对患者作必要的解释,然后由患者独立完成问卷;将资料量化后输入计算机,数据用统计软件SPSS11.0处理,问卷总分用x-±s进行t检验。结果:从113例慢性乙肝患者问卷平均得分为(11.54±2.65),基本达到及格要求,反映出患者有一定的健康信息储量,但缺乏较深层次的健康知识指导;慢性乙肝患者对乙肝相关知识的了解情况与文化程度及病程长短相关;对能解决实际问题的教育内容需求较多,最受欢迎的健康教育方式为发放健康手册,一病一卡(建立患者档案,医护定时上门)。结论:慢性乙肝患者有一定的健康信息储量,但不全面;患者对健康教育有较强的需求愿望;患者受着不同程度的心理压力,且知行未完全合一;因此, 对慢性乙型肝炎患者的健康教育需加强知识的深度和广度,重视教育内容和方式的有机结合,还要加强对慢性乙肝患者的心理疏导,情感支持,也是至关重要的。

  • The Correlation of Hepatocellular Carcinoma and Different Hepatitis B Virus Genotypes with Spontaneous YMDD Mutation

    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.

  • Efficacy of Peginterferon Alpha Initially Combined with Lamivudine or Adefovir in Treatment of HBeAg-positive Chronic Hepatitis B: A Systematic Review and Meta-analysis

    ObjectiveTo systematically review the efficacy of peginterferon alpha (PEG-IFNα) initially combined with lamivudine (LAM) or adefovir (ADV) in treatment of HBeAg-positive chronic hepatitis B (CHB) patients. MethodsWe electronically searched databases including The Cochrane Library (Issue 11, 2014), PubMed, CBM, CNKI, VIP, and WanFang Data from inception to December 2014, to collect randomized controlled trials (RCTs) about PEG-IFNα initially combined with LAM or ADV for HBeAg-positive CHB. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then, meta-analysis was performed by using RevMan 5.2 software. ResultsA total of 11 RCTs involving 2031 patients were included. The results of meta-analysis showed that: After 48 weeks of treatment, the HBsAg seroconversion rate of the PEG-IFNα plus ADV group was significantly higher than that of the PEG-IFNα monotherapy group (8.6% vs. 0%, OR=7.73, 95%CI 1.53 to 39.05, P=0.01) or the ADV monotherapy group (8.5% vs. 0%, OR=7.75, 95%CI 1.07 to 56.23, P=0.04); and the HBsAg seroclearance rate in the combination therapy group was significantly higher than that of the ADV monotherapy group (10.5% vs. 1.2%, OR=5.56, 95%CI to 2.14 to 14.47, P=0.0004). After 52 weeks of treatment, the HBsAg seroconversion rate of the PEG-IFNα plus LAM group was significantly higher than that of the PEG-IFNα monotherapy group (11.6% vs. 5.6%, OR=2.21, 95%CI 1.04 to 4.72, P=0.04). After 26 weeks of follow-up, no significant differences were found between the combination therapy group and the PEG-IFNα monotherapy group in HBsAg seroclearance rate and HBsAg seroconversion rate (all P values >0.05). ConclusionCurrent evidence shows that, compared with PEG-IFNα, LAM, or ADV monotherapy, PEG-IFNα plus LAM or ADV could improve the HBsAg seroclearance or seroconversion rate after 48-52 weeks of treatment for HBeAg-positive CHB, but this effect is still limited. Due to the limited quality and quantity of the included studies, more high quality studies are needed to verify the above conclusion.

  • Effect of Preoperative Serum HBeAg Status on Recurrence and Survival in Hepatocellular Carcinoma Patients after Radical Resection

    Objective To study the effect of HBeAg on recurrence and survival after radical resection of small (≤3 cm) hepatocellular carcinoma (HCC). Methods Two hundreds and twenty-three HCC patients undergone radical resection from 1999 to 2000 were divided into two groups according to serum HBeAg status, HBeAg positive group (n=73) and HBeAg negative group (n=150). The patients’ factors, operative factors and tumorous facors were studied retrospectively between the two groups. And risk factors of overall survival (OS) and disease-free survival (DFS) were analyzed. Results There were no significant differences in operative and tumorous factors between the two groups, but the HBeAg positive group were younger with more severe cirrhosis (P=0.004, P=0.008). The OS and DFS were significantly different between the HBeAg positive group and HBeAg negative group. The 1-, 3- and 5-year OS were 91.5%, 76.8%, 60.1% and 95.2%, 85.3%, 73.2%, respectively (P=0.053); and the 1-, 3- and 5-year DFS were 73.3%, 53.7%, 40.3% and 86.6%, 65.5%, 54.5%, respectively (P=0.002). Multivariate analysis revealed that age >50 years, HBeAg positive and macronodular cirrhosis were significantly related to OS, and HBeAg positive, multiple tumor nodulars were significantly related to DFS. Positive serum HBeAg status was an independent risk factor for both OS and DFS. Conclusion Positive serum HBeAg is closely related to early recurrence and survival after radical resection of patients with small HCC.

  • 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。
