RESUMO

Over 257 million individuals worldwide are chronically infected with the Hepatitis B Virus (HBV). Nucleos(t)ide analogues (NAs) are the first-line treatment option for most patients. Entecavir (ETV) and tenofovir disoproxil fumarate (TDF) are both potent, safe antiviral agents, have a high barrier to resistance, and are now off patent. They effectively suppress HBV replication to reduce the risk of cirrhosis, liver failure, and hepatocellular carcinoma (HCC). Treatment is continued long-term in most patients, as NA therapy rarely induces HBsAg loss or functional cure. Two diverging paradigms in the treatment of chronic hepatitis B have recently emerged. First, the public health focussed "treat-all" strategy, advocating for early and lifelong antiviral therapy to minimise the risk of HCC as well as the risk of HBV transmission. In LMICs, this strategy may be cost saving compared to monitoring off treatment. Second, the concept of "stopping" NA therapy in patients with HBeAg-negative disease after long-term viral suppression, a personalised treatment strategy aiming for long-term immune control and even HBsAg loss off treatment. In this manuscript, we will briefly review the current standard of care approach to the management of hepatitis B, before discussing emerging evidence to support both the "treat-all" strategy, as well as the "stop" strategy, and how they may both have a role in the management of patients with chronic hepatitis B.

RESUMO

INTRODUCTION: Chronic hepatitis B (CHB) is a global public health problem. Antiviral therapy is the primary treatment. Studies have shown that a combined therapy of traditional Chinese medicine (TCM) and conventional antiviral drugs has better efficacy than conventional antiviral for treatment of CHB. YinQiSanHuang-antiviral decoction (YQSH) is a TCM compound preparation that has shown an effect on anti-hepatitis B virus and on slowing progression of hepatitis B-related liver diseases. To evaluate the efficacy and safety of YQSH combined with entecavir and its preventive effect on hepatitis B cirrhosis, we designed this randomized, double-blind and placebo-controlled trial. The objective is that the combination of YinQiSanHuang-antiviral decoction with entecavir will reduce the annual incidence of liver fibrosis/cirrhosis to 1%. METHODS: This is a multicenter, randomized, placebo-controlled, double-blinded trial involving five hospitals. A total of 802 patients are randomly allocated to two groups: the YQSH group (n = 401) or the placebo group (n = 401). The YQSH group receives YQSH with entecavir; the placebo group receives granules of placebo with entecavir. Patients receive treatment for 52 weeks and then are followed up for 52 ± 2 weeks. The primary outcome measure is the annual incidence of cirrhosis. The secondary outcome measures are hepatitis B virus DNA negative rate, hepatitis B surface antigen negative rate, hepatitis B e antigen seroconversion rate, liver function (alanine aminotransferase, aspartate aminotransferase , gamma-glutamyl transferase , alkaline phosphatase , serum albumin, and total bilirubin), spleen thickness, evaluation scores of patients' clinical symptoms, and safety assessment. Outcomes will be assessed at baseline and after treatment. DISCUSSION: Combination therapy could become a trend for treatment of CHB, and this trial expects to provide credible clinical evidence for the future combination of TCM and conventional antiviral drugs for the treatment of CHB. TRIAL REGISTRATION: Chinese Clinical Trial Registry: ChiCTR1900021521. Registered on 25 February 2019.

RESUMO

INTRODUCTION AND OBJECTIVES: The prevalence of alcohol, tobacco, and coffee use and association with liver health among North Americans with Chronic Hepatitis B (CHB) infection has not been well described. MATERIALS AND METHODS: The Hepatitis B Research Network includes an observational study of untreated CHB adults enrolled at 21 sites in the United States and Canada. Alcohol use was categorized as none, moderate, and at-risk based on the definition from the National Institute on Alcohol Abuse and Alcoholism; tobacco use as never, current and former; coffee use as none, 1-2 cups/day, and ≥3 cups/day. Linear regression and linear mixed models were used to associate lifestyle behaviors with ALT and FIB-4 values. RESULTS: 1330 participants met eligibility: 53% males, 71% Asian and the median age was 42 years (IQR: 34-52). Median ALT was 33U/L (IQR: 22-50), 37% had HBV DNA <103IU/mL, 71% were HBeAg negative, and 65% had a FIB-4 <1.45. At baseline, 8% of participants were at-risk alcohol drinkers, 11% were current smokers and 92% drank <3 cups of coffee/day. Current tobacco and 'at-risk' alcohol use, were significantly associated with elevated ALT levels in univariable analyses, however, these associations were not statistically significant when controlling for sociodemographic and HBV characteristics. CONCLUSIONS: In this large diverse cohort of untreated CHB participants, at-risk alcohol use, current tobacco use and limited coffee consumption did not have an association with high ALT and FIB-4 values. In contrast, significant associations were found between the frequency of these lifestyle behaviors and sociodemographic factors.

RESUMO

Chronic hepatitis B virus (HBV) infection is a serious public health issue. Vitamin D is involved in various pathophysiological mechanisms as an immune modulator and the deficiency rate of vitamin D is prevalent in chronic liver disease. Fucoidan exerts anti-inflammatory, anticoagulant, antitumor, antimetastatic, and antiangiogenetic effects; however, its effect on the immune responses of HBV patients is unclear. This study investigated how 25(OH)Vitamin D status affected the effectiveness of oligo fucoidan in patients with HBV infection in the immune tolerance phase. Fifty-one patients received oligo fucoidan 4400 mg/day for 48 weeks. Flow cytometry was used to detect T lymphocyte markers (CD3+CD4+, CD3+CD8+, CD4+CD45RO+, CD8+CD45RO+). The levels of white blood cell (WBC), platelets (PLT), and albumin were decreased after 48 weeks of supplementation (p < 0.05). Percentages of CD3+CD8+ and CD8+CD45RO+ cells were decreased after 12 weeks of supplementation (p < 0.05). In patients with adequate vitamin D, HBV-DNA concentrations decreased and the proportion of CD4+CD45RO+ and CD8+CD45RO+ cells increased upon oligo fucoidan supplementation. The HBeAg status of one vitamin D-adequate patient changed from positive to negative at the 12th week of supplementation. The oligo fucoidan may regulate immune effects in patients with HBV infection, and the 25(OH)Vitamin D status might have affected the effectiveness of oligo fucoidan.

RESUMO

To evaluate the efficacy and safety of Gantaishu Capsules in the treatment of viral B hepatitis. The randomized controlled trials( RCT) retrieved from Cochrane Library,PubMed,Sino Med,CNKI,Wan Fang and VIP were enrolled. The methodology quality of the included studies was evaluated,and a Meta-analysis was performed using Rev Man 5. 3 software. A total of six randomized controlled trials were included. Meta-analysis results showed that the similarities in the negative conversion rate of HBe Ag( RR = 2. 09,95%CI[0. 90,4. 85],P = 0. 09,I2= 0%),the HBV-DNA negative rate( RR = 1. 49,95% CI[0. 56,3. 95],P = 0. 43,I2= 0%) and the changes in ALT levels before and after treatment( RR =-6. 28,95%CI[-72. 83,60. 27],P = 0. 85,I2= 99%),with no statistical difference. In terms of quality of life,Gantaishu Capsules can significantly alleviate the symptoms of hepatitis B patients,with less adverse reactions. Gantaishu Capsules and Dongbao Gantai Tablets were similar in antiviral effect. In this term,Gantaishu Capsules was superior to Dangfei Liganning Capsules. It can significantly alleviate the symptoms of chronic hepatitis B patients,with a good clinical safety.Therefore,it can be applied in the case of syndrome differentiation and treatment. In view of the low quality of the included studies,more high-quality clinical trials were required to confirm its efficacy.

RESUMO

BACKGROUND: Hepatitis B virus (HBV) infection is a liver disease caused by hepatitis B virus, which may lead to serious complications such as cirrhosis and hepatocellular carcinoma. People with HBV infection may also have coinfections including HIV and other hepatitis viruses (hepatitis C or D), and coinfections may increase the risk of all-cause mortality. Chronic HBV infection increases morbidity, psychological stress, and it is an economic burden on people with chronic hepatitis B and their families. Radix Sophorae flavescentis, a herbal medicine, is administered mostly in combination with other drugs or herbs. It is believed that it decreases discomfort and prevents the replication of the virus in people with chronic hepatitis B. However, the benefits and harms of Radix Sophorae flavescentis on patient-centred outcomes are unknown, and its wide usage has never been established with rigorous review methodology. OBJECTIVES: To assess the benefits and harms of Radix Sophorae flavescentis versus other drugs or herbs in people with chronic hepatitis B. SEARCH METHODS: We searched The Cochrane Hepato-Biliary Group Controlled Trials Register, CENTRAL, MEDLINE, Embase, and seven other databases to December 2018. We also searched the World Health Organization International Clinical Trials Registry Platform (www.who.int/ictrp), ClinicalTrials.gov (www.clinicaltrials.gov/), and the Chinese Clinical Trial Registry for ongoing or unpublished trials to December 2018. SELECTION CRITERIA: We included randomised clinical trials, irrespective of publication status, language, or blinding, comparing Radix Sophorae flavescentis versus other drugs or herbs for people with chronic hepatitis B. In addition to chronic hepatitis B, participants could also have had cirrhosis, hepatocellular carcinoma, or any other concomitant disease. We excluded polyherbal blends containing Radix Sophorae flavescentis. We allowed cointerventions when the cointerventions were administered equally to all intervention groups. DATA COLLECTION AND ANALYSIS: Review authors in pairs individually retrieved data from published reports and after correspondence with investigators. Our primary outcomes were all-cause mortality, serious adverse events, and health-related quality of life. Our secondary outcomes were hepatitis B-related mortality, hepatitis B-related morbidity, and adverse events considered 'not to be serious'. We presented the meta-analysed results as risk ratios (RR) with 95% confidence intervals (CI). We assessed the risk of bias using domains with predefined definitions. We conducted Trial Sequential Analyses to control the risks of random errors. We used GRADE methodology to evaluate our certainty in the evidence (i.e. "the extent of our confidence that the estimates of the effect are correct or are adequate to support a particular decision or recommendation"). MAIN RESULTS: We included 10 randomised clinical trials with 898 participants. We judged all trials at high risk of bias. The trials covered oral capsules, intravenous infusion, intramuscular injection, and acupoint (a specifically chosen site of acupuncture) injection of Radix Sophorae flavescentis with a follow-up period from 1 to 12 months. The drugs being used as a comparator were lamivudine, adefovir, interferon, tiopronin, thymosin, or other Chinese herbs. Two trials included children up to 14 years old. Participants in one trial had cirrhosis in chronic hepatitis B. None of the trials reported all-cause mortality, health-related quality of life, serious adverse events, hepatitis B-related mortality, or morbidity. We are uncertain as to whether Radix Sophorae flavescentis has a beneficial or harmful effect on adverse events considered 'not to be serious' (RR 0.86, 95% CI 0.42 to 1.75; I2 = 0%; 2 trials, 163 participants; very low-certainty evidence), as well as if it decreases or increases the proportion of participants with detectable HBV-DNA (RR 1.14, 95% CI 0.81 to 1.63; I2 = 92%; 8 trials, 719 participants; very low-certainty evidence). Radix Sophorae flavescentis showed a reduction in the proportion of participants with detectable hepatitis B virus e-antigen (HBeAg) (RR 0.86, 95% CI 0.75 to 0.98; I2 = 43%; 7 trials, 588 participants; very low-certainty evidence).Two of the 10 trials were not funded, and one received academic funding. The remaining seven trials provided no information on funding.The randomisation process in another 109 trials was insufficiently reported to ensure the inclusion of any of these studies in our review. AUTHORS' CONCLUSIONS: The included trials lacked data on all-cause mortality, health-related quality of life, serious adverse events, hepatitis-B related mortality, and hepatitis-B related morbidity. The evidence on the effect of Radix Sophorae flavescentis on the proportion of participants with adverse events considered 'not to be serious' and on the proportion of participants with detectable HBV-DNA is still unclear. We advise caution regarding the results of Radix Sophorae flavescentis showing a reduction in the proportion of people with detectable HBeAg because the trials were at high risk of bias, because it is a non-validated surrogate outcome, and because of the very low certainty in the evidence. As we were unable to obtain information on a large number of studies regarding their trial design, we were deterred from including them in our review. Undisclosed funding may have influence on trial results and lead to poor design of the trial. In view of the wide usage of Radix Sophorae flavescentis, we need large, unbiased, high-quality placebo-controlled randomised trials assessing patient-centred outcomes.

RESUMO

BACKGROUND/PURPOSE: Although coffee consumption has been associated with decreased risk of liver fibrosis progression, cirrhosis or hepatocellular carcinoma in patients with HCV infection or fatty liver diseases, its effect on hepatitis B patients remains unclear. We aimed to examine the effect of coffee consumption on liver fibrosis progression and cirrhosis-related complications in patients with chronic HBV infection. METHODS: Coffee consumption was assessed in 2604 participants who were previously recruited from a population-based GERD survey. The primary endpoints of this study were the impact of coffee consumption on the development of cirrhosis-related complications, including liver cirrhosis, esophageal varices, or hepatocellular carcinoma at the end of 5-year follow-up. The secondary endpoints were the declines of serum predicting indices of liver fibrosis (AST/ALT, APRI, FIB-4, Hui score) or liver function tests (AST, ALT). RESULTS: 328 patients with chronic HBV infection were enrolled into this study. At baseline, coffee consumption was associated with higher education level, more frequent tobacco use and normal blood pressure (p < 0.05 for all). Patients with higher coffee consumption had a significant lower serum AST, APRI and FIB-4 index value than non-coffee drinkers [adjusted HR 0.30, 95% CI(0.11-0.82) for AST; 0.30, 95% CI (0.11-0.84) for APRI; 0.30, 95% CI (0.13-0.69) for FIB-4]. However, higher coffee consumption didn't change serum AST levels, APRI, FIB-4 index values or incidences of cirrhosis-related complications at the end of 5-year follow-up. CONCLUSION: Coffee consumption was not associated with fibrosis progression or HCC risk in chronic hepatitis B patients over the 5-year observation period.

RESUMO

BACKGROUND: The domestic prevalence of chronic hepatitis B (CHB) in China is 7.18% in 2006, imposing great societal healthcare burdens. Nucleot(s)ide analogues (NUCs) anti-hepatitis B virus (HBV) therapies are widely applied despite the relatively low rate of seroconversion and high risk of drug-resistant mutation. More effective treatments for CHB deserve further explorations. Combined therapy of NUCs plus Chinese herbal medicine (CHM) is widely accepted in China, which is recognized as a prospective alternative approach. The study was primarily designed to confirm the hypothesis that Tiaogan-Yipi Granule (, TGYP) or Tiaogan-Jianpi-Jiedu Granule (, TGJPJD) plus entecavir tablet (ETV) was superior over ETV monotherapy in enhancing HBeAg loss rate. METHODS: The study was a nationwide, large-scale, multi-center, double-blind, randomized, placebo-controlled trial with a designed duration of 108 weeks. A total of 16 hospitals and 596 eligible Chinese HBeAg positive CHB patients were enrolled from November 2012 to September 2013 and randomly allocated into 2 groups in 1:1 ratio via central randomization system: experimental group (EG) and control group (CG). Subjects in EG received CM formulae (TGYP or TGJPJD, 50 g per dose, twice daily) plus ETV tablet (or ETV placebo) 0.5 mg per day in the first 24 weeks (stage 1), and CHM granule plus ETV tablet (0.5 mg per day) from week 25 to 108 (stage 2). Subjects in CG received CHM Granule placebo plus ETV tablet (0.5 mg per day) for 108 weeks throughout the trial. The assessments of primary outcomes (HBV serum markers and HBV-DNA) were conducted by a third-party College of American Pathologists (CAP) qualified laboratory. Adverse effects were observed in the hospitals of recruitment. DISCUSSION: The study was designed to compare the curative effect of CM plus ETV and ETV monotherapy in respect of HBeAg loss, which is recognized by the European Association for the Study of the Liver as "a valuable endpoint". We believe this trial could provide a reliable status for patients' "journey" towards durable responses after treatment discontinuation. The trial was registered before recruitment on Chinese Clinical trial registry (No. ChiCTR-TRC-12002784, Version 1.0, 2015/12/23).

RESUMO

BACKGROUND/AIMS: To investigate the clinical effects of the combination therapy with Bushen Formula (BSF) plus enticavir (ETV) on chronic hepatitis B (CHB) patients with suboptimal response to ETV and explore the regulatory mechanisms of BSF on B cells-mediated humoral immunity. METHODS: Sixty-four HBeAg-positive CHB patients with suboptimal response to ETV were enrolled, and were randomly assigned into control group (C-Group, placebo combined with ETV for 12 months) or treatment group (T-Group, BSF combined with ETV for 12 months). Serum samples from 57 treatment-naïve CHB patients and 15 healthy controls were collected. Serum HBV DNA levels were evaluated by real-time PCR. Characteristics of peripheral blood B-cell subtypes were analyzed by flow cytometry. Serum HBV markers and B cell-activating factor (BAFF) levels were detected by ELISA. Chinese medicine symptom complex score was evaluated and recorded. RESULTS: After treatment, the rates of patients with a reduction of HBsAg > 0.5 log10 IU/ml or 1.0 log10 IU/ml and the rates of HBeAg clearance in T-Group were all higher than those in C-group, with no significant intergroup difference. Only in T-Group, Chinese medicine symptom complex score and the frequency of total B cells were significantly decreased, and the frequencies of Bm1, CD24+CD27-switched B cells and plasma cells were markedly increased after treatment compared with those before treatment. Compared with healthy controls, serum BAFF levels in treatment-naïve CHB patients were increased, and there was a significant positive correlation between serum BAFF and HBsAg levels. However, serum BAFF levels did not differ after treatment in T-Group and C-Group. CONCLUSIONS: The combination therapy with BSF plus ETV promotes the reduction of HBsAg level and the clearance of HBeAg in CHB patients with partial response to ETV through regulating the differentiation of B-cell subsets.

RESUMO

OBJECTIVE: To explore the effect of Telbivudine (LDT) Tablet combined with Jianpi Bushen Recipe (JBR) on serum hepatitis B virus (HBV) specific cytotoxic T lymphocyte (CTL) and HBeAg seroconversion in chronic hepatitis B (CHB) patients. METHODS: Totally 90 HBeAg-positive and human leukocyte antigen (HLA)-A2 positive CHB patients were randomly assigned to the treatment group and the control group, 45 cases in each group. Patients in the treatment group took LDT Tablet (600 mg, once per day) combined with JBR granule (twice per day), while those in the control group took LDT Tablet alone. The therapeutic course for all was one year. HBV DNA negative conversion rate, HBeAg seroconversion rate, and level of HBV specific CTL were compared after 1 year treatment; liver function, drug resistance mutations, and adverse reactions were also compared between the two groups. RESULTS: After 1 year treatment, HBV DNA negative conversion rate and HBeAg seroconversion rate were 88.89% (40/45) and 40.00% (18/45) in the treatment group, higher than those of the control group [68.89% (31/45) and 20.00% (9/45)], with statistical difference (P < 0.05). Level of HBV specific CTL in the treatment group was 0.78% +/- 0.09% after treatment, higher than that of the control group after 1 year treatment (0.54% +/- 0.11%) and that before treatment (0.36% +/- 0.07%), with statistical difference (P < 0.01). Level of HBV specific CTL in 27 patients with HBeAg seroconversion was 0.81% 0.10%, higher than that of 63 patients without HBeAg seroconversion (0.60% +/- 0.09%), with statistical difference (P < 0.01). ALT returned to normal in 44 cases of the treatment group (97.78%), while it was 42 cases (93.33%) of the control group, with no statistical difference between the two groups (P > 0.05). Total bilirubin (TBil) in the two groups all turned to normal. rtM204I variation occurred in 1 case (2.22%) of the treatment group and 2 cases (4.44%) in the control group. No obvious adverse reaction occurred in the two groups. CONCLUSION: LDT Tablet combined with JBR could elevate levels of HBV specific CTL and HBeAg seroconversion in CHB patients.

RESUMO

OBJECTIVE: To observe the correlation between constitution of yin deficiency syndrome (YDS) and polymorphism of HLA-DQA1/treatment response of Peg-lFNalpha therapy in HBeAg positive chronic hepatitis B (CHB) patients, and to explore constitution of Chinese medicine (CM) in response of interferon therapy. METHODS: Totally 120 HBeAg positive CHB patients who were treated with Peg-IFNalpha were enrolled, and assigned to YDS group (59 cases) and non-YDS group (61 cases) according to classification of CM constitutions. All patients were subcutaneously injected with Peg-IFNalpha-2b (1.0 microg/kg body weight) or Peg-IFNalpha-2a (180 microg), once per week. Effective efficacy was primarily judged when complete response (CR) or partial response (PR) was obtained at month 6. Those with CR or PR completed 1 year therapeutic course. HLA-DQA1 gene types were detected by polymerase chain reaction sequence specific primers (PCR-SSP). The distribution difference of CM constitutions in patients with CR or PR and their inter-group HLA-DQA1 allele frequency were compared. RESULTS: Different treatment responses of Peg-IFNalpha were observed in CHB patients of two different CM constitutions. The ratio of CR + PR was 61.0% (36/59) in YDS group, obviously lower than that in NYDS group [78.7% (48/61), P < 0. 05]. Patients with CR had a lower allele frequency of HLA-DQA1 * 0501 than those with no-response [14.8% (8/54) vs. 30.6% (22/72)] with statistical difference (P < 0.05). Patients with CR had a higher allele frequency of HLA-DQA1 * 0601 than those with no-response [18.5% (10/54) vs. 5.6% (4/72)] with statistical difference (P < 0.05). The allele frequency of HLA-DQA1 * 0301 was lower in YDS group than in non-YDS group [2. 5% (3/118) vs. 9.8% (12/122)] with statistical difference (P < 0.05). The allele frequency of HLA-DQA1 * 0501 was higher in YDS group than in non-YDS group [33.9% (40/118) vs. 18.9% (23/122)] with statistical difference (P < 0.05). Yet statistical significance was lost after adjustment (Pc > 0.05 for both). CONCLUSIONS: Both constitutions of CM and HLA-DQA1 gene polymorphism af- fect HBeAg positive CHB patients' response to Peg-INFalpha. Constitutions of YDS and HLA-DQA1 * 0501 was not favorable to response, their association needed to be further studied.

RESUMO

OBJECTIVE: To explore clinical efficacy of Yiguanjian Decoction (YD) combined Adefovir Dipivoxil Tablet (ADT) in treating HBeAg negative chronic viral hepatitis B (CVHB) active compensated liver cirrhosis (LC) patients. METHODS: Totally 68 HBeAg negative CVHB active compensated LC patients initially treated were assigned to the treatment group and the control group using random digit table, 34 in each group. Patients in the control group took ADT alone, 10 mg each time, once per day. Those in the treatment group additionally took YD, one dose per day. The therapeutic course for all was 48 weeks. Levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBil) were detected once in every two weeks. Hepatitis B virus (HBV)-DNA and four items of serum liver fibrosis [procollagen type I (PCN), hyaluronidase (HA), procollagen III peptide (PCIII), laminin (LN)] were detected once per every 4 weeks. Abdominal ultrasound B was performed before and after treatment. The inner diameter of the portal vein and the size of spleen were recorded. The fibrosis degree of liver was evaluated using Fibroscan. Efficacy of Chinese medicine (CM) was evaluated between the two groups before and after treatment using CM syndrome integrals. Efficacy of Western medicine (WM) was also evaluated between the two groups using Child-Pugh grading. Results Compared with before treatment in the same group, ALT and AST levels restored to normal levels, HBV-DNA turned negative (HBV-DNA < or = 1 x 10(2)) in the two groups after 48-week treatment. Besides, levels of TBil, ALB, PCIV, HA, PCIII, and LN obviously decreased (P < 0.05, P < 0.01). Results of ultrasound B showed the inner diameter of the portal vein and the size of spleen decreased. Fibroscan results showed that the elasticity value of the liver obviously decreased (P < 0.05). Besides, post-treatment levels of PCIV, HA, PCEJ, and LN, and the elasticity value of the liver decreased more obviously in the treatment group than in the control group (P < 0.01). There was no statistical difference in post-treatment levels of ALT, AST, TBil, ALB, inner diameter of the portal vein, or the size of spleen between the two groups (P > 0.05). Compared with before treatment in the same group, scores of Chinese medical syndrome and Child-Pugh scores decreased in the two groups after treatment (P < 0.05, P < 0.01). Besides, scores of Chinese medical syndrome decreased more obviously in the treatment group than in the control group (P < 0.05). The effective rate was 8824% (30/34) in the treatment group, higher than that of the control group [67.65% (23/34)] with statistical difference (P <0.05). Conclusion Combined treatment of YD and ADT could significantly improve symptoms of CM and fibrosis degree of liver of HBeAg negative CVHB active compensated LC patients.

RESUMO

OBJECTIVE: To evaluate the effect of long-term therapy with entecavir and Fufang Biejia Ruangan tablet in patients with chronic hepatitis B (CHB)-associated fibrosis and explore the synergistic therapy that accelerates the reversion of liver fibrosis. METHODS: A total of 197 patients with CHB-associated fibrosis were recruited from Nanfang Hospital between June, 2010 and June, 2015. The patients were divided into two groups after matching for age, gender and liver stiffness measurement (LSM), namely group A (n=98) treated with Fufang Biejia Ruangan Tablet plus entecavir, and group B (n=99) to receive entecavir only. HBV DNA quantification, HBV serological indicators, blood biochemical indexes, and results of abdominal ultrasound and FibroScan were recorded every 12 weeks. FibroScan values were converted to Metavir staging. RESULTS: Both groups showed significant decreases in serum levels of HBV DNA, alanine aminotransferase (ALT), and LSM value from baseline (all P<0.05). The median time to achieve Metavir fibrosis staging improvement were 72 weeks in group A and 96 weeks in group B (P<0.05), and the median time to achieve ALT and AST normalization were 12 and 24 weeks in Group A, respectively, significantly shorter than the time in group B (P<0.05). No significant difference was found between the two groups in HBV DNA undetectable rate and HBeAg seroconversion rate. CONCLUSION: The combination therapy with Fufang Biejia Ruangan tablet and entecavir produces a stronger efficacy than entecavir alone in the treatment of chronic hepatitis B patients with liver fibrosis, and Fufang Biejia Ruangan tablet shows an obvious hepatoprotective effect in these patients.

RESUMO

INTRODUCTION: Traditional Chinese herbs are widely used for the treatment of chronic hepatitis B (CHB) in China. The aim of this study was to perform a meta-analysis of randomized controlled trials (RCTs) comparing peginterferon therapies with peginterferon plus Chinese herbal therapies in hepatitis B e antigen (HBeAg)-positive CHB patients. METHODOLOGY: The main biomedical databases were searched to identify RCTs that compared the efficiency of peginterferon with peginterferon plus Chinese herbs in CHB patients. RESULTS: The literature search yielded 616 studies, and 8 RCTs (624 patients) matched the selection criteria. Combined therapies of peginterferon plus Chinese herbal therapies were superior to peginterferon therapies alone in achieving the serum HBV DNA clearance rate (64.5% vs. 45.0%), serum HBeAg clearance rate (47.4% vs. 33.5%), and HBeAg seroconversion rates (39.2% vs. 23.1%) at the end of treatment. Combined therapies were more effective than peginterferon alone therapies in the improvement of liver fibrosis related biomarkers, including hyaluronic acid, procollagen type III, type IV collagen, and lamina. Combined therapies also resulted in fewer relapses, fewer adverse events, and more rapid alanine transaminase normalization. CONCLUSIONS: The current evidence suggests that peginterferon plus Chinese herbal therapies were associated with higher virological response than peginterferon alone in HBeAg-positive CHB patients.

RESUMO

AIM: To investigate the frequency of mutations in pre-core (pre-C) and basic core promoter (BCP) regions of hepatitis B virus (HBV) from Shanxi Province, and the association between mutations and disease related indexes. METHODS: One hundred chronic hepatitis B patients treated at Shanxi Province Hospital of Traditional Chinese Medicine were included in this study. PCR-reverse dot blot hybridization and mismatch amplification mutation assay (MAMA)-PCR were used to detect the mutations in the HBV pre-C and BCP regions. HBV DNA content and liver function were compared between patients with mutant HBV pre-C and BCP loci and those with wild-type loci. The consistency between PCR-reverse dot blot hybridization and MAMA-PCR for detecting mutations in the HBV pre-C and BCP regions was assessed. RESULTS: Of the 100 serum samples detected, 9.38% had single mutations in the pre-C region, 29.17% had single mutations in the BCP region, 41.67% had mutations in both BCP and pre-C regions, and 19.79% had wild-type loci. The rates of BCP and pre-C mutations were 65.7% and 34.3%, respectively, in hepatitis B e antigen (HBeAg) positive patients, and 84.6% and 96.2%, respectively, in HBeAg negative patients. The rate of pre-C mutations was significantly higher in HBeAg negative patients than in HBeAg positive patients (χ (2) = 26.62, P = 0.00), but there was no significant difference in the distribution of mutations in the BCP region between HBeAg positive and negative patients (χ (2) = 2.43, P = 0.12). The presence of mutations in the pre-C (Wilcoxon W = 1802.5, P = 0.00) and BCP regions (Wilcoxon W = 2906.5, P = 0.00) was more common in patients with low HBV DNA content. Both AST and GGT were significantly higher in patients with mutant pre-C and BCP loci than in those with wild-type loci (P < 0.05). PCR-reverse dot blot hybridization and MAMA-PCR for detection of mutations in the BCP and pre-C regions had good consistency, and the Kappa values obtained were 0.91 and 0.58, respectively. CONCLUSION: HBeAg negative patients tend to have HBV pre-C mutations. However, these mutations do not cause increased DNA copies, but associate with damage of liver function.

RESUMO

To observe the clinical efficacy of spleen, liver and kidney-strengthening formula combined with polyethylene glycol interferon in the treatment of HBeAg positive chronic hepatitis B(HP-HBV).One hundred and twenty-six patients with HP-HBV, who were treated in the hospital from June 2012 to December 2014, were selected and injected with polyethylene glycol interferon α-2a(or α-2b). The treatment course for the patients lasted for 24 weeks. Base on the level of HBV-DNA, patients are divided into response group and poor response group. According to random number table, the poor response group were randomized into control group and test group. Patients in the control group were injected with polyethylene glycol interferon α-2a(or α-2b), and patients in the test group were treated with spleen, liver and kidney-strengthening formula combined with polyethylene glycol interferon. Clinical efficacies of the 2 groups were observed, and changes in the level of HBeAg, ALT and HBV-DNA were observed before treatment and at the 24th week after treatment, and virological and serological response, biochemical responses, integral clinical symptoms and signs, adverse reactions were observed after 48 weeks of treatment.After 24 weeks of treatment, the response group was significantly better than the poor response group in HBeAg, ALT and the level of HBV-DNA(P<0.05). After 48 weeks of treatment, there was statistical significance in HBV-DNA negative conversion rate, HBeAg negative conversion rate between the 2 groups(P<0.05), and the test group was better in the two indicators. And the test group was significantly lower than the control group in clinical symptoms and signs score at the 48th week after treatment(P<0.05), with a significantly lower adverse reaction rate than the control group(P<0.05).Combination of spleen, liver and kidney-strengthening formula and polyethylene glycol interferon α-2a was effective and safe in the treatment of chronic hepatitis B, and so worth promoting in clinic.

RESUMO

BACKGROUND: Entecavir (ETV) is a first-line, oral antinucleoside agent for the treatment of chronic hepatitis B patients. Despite its high potency, some patients may still be viremic after prolonged therapy with ETV monotherapy. Long-term outcome data comparing maintained ETV monotherapy to alternative therapies in persistently viremic patients are limited. Our goal was to compare complete viral suppression (CVS) rates [hepatitis B DNA (HBV DNA)<40 to 60 IU/mL] with alternative therapies to continued ETV monotherapy in ETV partial responders. METHODS: This is a retrospective cohort study consisting of 86 consecutive treatment-naive, ETV=0.5 mg partial responders (detectable HBV DNA after ≥12 mo on ETV) who maintained ETV=0.5 mg daily (n=29) or switched to either ETV=1.0 mg daily (n=32) or ETV/tenofovir (TDF)=0.5 mg/300 mg (n=25) in 3 US GI/liver clinics from January 2005 to January 2012. Patients were identified by International Classification of Diseases, Ninth Revision query and data were collected by individual chart review. For those who remained on ETV=0.5 mg, comparison at regimen "switch time" was done using values at 12 months from initial ETV therapy. Rates of CVS were evaluated using Kaplan-Meier methods. Multivariate Cox proportional hazard models were used to estimate hazard ratio (HR) relating to potential predictors to the desirable outcomes of CVS. RESULTS: In all therapy groups, the majority of patients were Asian (93.1% to 100.0%), male (64.0% to 68.8%), and hepatitis B e antigen-positive (95.8% to 100.0%) and had similar baseline alanine aminotransferase (ALT) levels. However, baseline HBV DNA (7.0 vs. 7.9 vs. 7.8 log10 IU/mL, P=0.05) and HBV DNA at regimen switch point (2.9 vs. 3.7 vs. 3.6 log10 IU/mL, P=0.0014) were lower in the ETV=0.5 mg cohort compared with those switched to ETV=1.0 mg or ETV/TDF, respectively. The ETV=0.5 mg cohort also had the shortest duration of ETV=0.5 mg therapy before switch (11.8 vs. 13.5 vs. 19.2 mo, P<0.0001). After the switch point, more patients on ETV/TDF achieved CVS compared with those on ETV=0.5 mg or ETV=1.0 mg at month 6 (77.3% vs. 13.8% vs. 9.4%), month 12 (86.4% vs. 40.5% vs. 25.0%), and month 18 (100% vs. 70.2% vs. 33.3%). Compared with the ETV=0.5 mg and ETV=1.0 mg groups, the ETV/TDF group also had higher rates of ALT normalization at month 6 (73.0% vs, 46.4% vs. 63.0%), month 12 (79.7% vs. 69.5% vs. 77.9%), and month 18 (100.0% vs. 69.5% vs. 86.8%), respectively. The multivariate analyses, inclusive of baseline age and treatment duration on initial therapy with ETV=0.5 mg, indicated that the ETV/TDF combination (HR=12.19, P<0.0001) was independently and positively associated with CVS, whereas high HBV DNA levels at baseline (HR=0.77, P=0.02) and at switch point (HR=0.46, P=0.002) were negatively associated with CVS. ETV=1.0 mg dose was not a predictor for CVS compared with ETV=0.5 mg. CONCLUSIONS: Following adjustments for HBV DNA levels and prior treatment duration, ETV/TDF combination therapy independently predicted superior viral suppression and ALT normalization in partial responders to ETV=0.5 mg daily compared with ETV=0.5 mg or ETV=1.0 mg monotherapy. In patients who continued to be viremic after 12 months of ETV=0.5 mg, one third were still viremic after another 18 months on the same therapy. Alternative therapies should be considered for these patients.

RESUMO

To verify the effect of echinacoside on replication and antigen expression of hepatitis B virus (HBV) by using HBV-transfected HepG2. 2. 15 cells as the in vitro model. The ELISA method was used to determine HBeAg and HBsAg levels in cellular supernatants. The effect of echinacoside on HBV replication was studied by using HBV transgenic mice as the in vivo model. First of all, the HBV DNA level in hepatic tissues was quantified with PCR method. Meanwhile, the serum transaminase levels and hepatic pathological changes were also evaluated. Subsequently, HBV transgenic mice were divided into five groups: the control group, the lamivudine group (50 mg · kg(-1)) and echinacoside high, medium and low dose group (50, 25 and 12.5 mg · kg(-1)). The mice were orally administered with drugs once per day for 30 days. At the 31st day, the mice serum was separated to measure HBsAg, HBeAg and HBV DNA. Additionally, the liver HBV DNA level and histopathological change were detected. The results indicated that echinacoside at 50 and 100 mg · L(-1) suppressed significantly HBsAg and HBeAg expressions on the sixth day, with the maximum inhibition ratios of 42.68% and 46.29%; And echinacoside at 100 mg · L(-1) also showed an inhibitory effect on HBV DNA. Besides, echinacoside at 50 mg · kg(-1) inhibited significantly HBsAg and HBeAg expressions of HBV transgenic mice, with the inhibition ratios of 42.82% and 29.12%, and reduced markedly the serum HBV DNA level in HBV transgenic mice. In conclusion, the study suggested that echinacoside has a strong effect against HBV replication and antigen expression.

RESUMO

BACKGROUND: Seven drugs are licensed for the treatment of chronic hepatitis B (CHB) in the United Kingdom. Which initial treatment, secondary therapy, and whether antivirals should be given alone or in combination are questions of considerable uncertainty. OBJECTIVE: The aim of this model was to undertake a comprehensive economic evaluation of all antiviral treatments for CHB to recommend the most cost-effective therapeutic sequence. METHODS: We developed a probabilistic Markov model to compare the cost-effectiveness of all clinically relevant antiviral treatment sequences for nucleos(t)ide-naive adults with hepatitis B e-antigen (HBeAg)-positive or HBeAg-negative CHB. Relative rates of HBeAg seroconversion and viral suppression were obtained from a network meta-analysis. Data on mortality, antiviral drug resistance, durability of response, adverse events, and costs were obtained from published literature. Results are reported in terms of lifetime costs, quality-adjusted life-years (QALYs), and expected net benefit. RESULTS: In the base-case analysis, pegylated interferon alpha-2a (peg-IFN α-2a) followed by tenofovir disoproxil fumarate was most effective and cost-effective in HBeAg-positive patients, with a cost of £7488 per QALY gained compared with no treatment. In HBeAg-negative patients, peg-IFN α-2a followed by entecavir was most effective and cost-effective, with a cost of £6981 per QALY gained. The model was robust to a wide range of sensitivity analyses. CONCLUSIONS: Peg-IFN α-2a followed by tenofovir disoproxil fumarate or entecavir is the most effective antiviral treatment strategy for people with both variants of CHB. At a cost of less than £10,000 per QALY gained, these sequences are considered cost-effective in England and Wales. The results of this analysis were used to inform 2013 National Institute for Health and Care Excellence guideline recommendations.

RESUMO

BACKGROUND/AIMS: The efficacy of tenofovir disoproxil fumarate (TDF) for the treatment of chronic hepatitis B (CHB) patients following prior treatment failure with multiple nucleos(t)ide analogues (NAs) is not well defined, especially in Asian populations. In this study we investigated the efficacy and safety of TDF rescue therapy in CHB patients after multiple NA treatment failure. METHODS: The study retrospectively analyzed 52 CHB patients who experienced failure with two or more NAs and who were switched to regimens containing TDF. The efficacy and safety assessments included hepatitis B virus (HBV) DNA undetectability, hepatitis B envelop antigen (HBeAg) seroclearance, alanine transaminase (ALT) normalization and changes in serum creatinine and phosphorus levels. RESULTS: The mean HBV DNA level at baseline was 5.4 ± 1.76 log10 IU/mL. At a median duration of 34.5 months of TDF treatment, the cumulative probabilities of achieving complete virological response (CVR) were 25.0%, 51.8%, 74.2%, and 96.7% at 6, 12, 24, and 48 months, respectively. HBeAg seroclearance occurred in seven of 48 patients (14.6%). ALT levels were normalized in 27 of 31 patients (87.1%) with elevated ALT at baseline. Lower levels of HBV DNA at baseline were significantly associated with increased CVR rates (p < 0.001). However, CVR rates did not differ between TDF monotherapy or combination therapy with other NAs, and were not affected by mutations associated with resistance to NAs. No significant adverse events were observed. CONCLUSIONS: TDF is an efficient and safe rescue therapy for CHB patients after treatment failure with multiple NAs.
