The objective of the ...Currently available monotherapies of oral nucleoside/nucleotide analogs or interferon are unable to achieve a sustained and effective response in most of patients with chronic hepatitis B（CHB）. The objective of the present study was to compare the efficacy and safety of pegylated interferon（Peg-IFN） alpha-2b plus adefovir dipivoxil combination therapy versus Peg-IFN alpha-2b alone. Sixty-one HBeAg-positive chronic hepatitis B patients were randomized to receive Peg-IFN alpha-2b alone（1.5 μg/kg once weekly） or Peg-IFN alpha-2b plus adefovir（10 mg daily） for up to 52 weeks. Efficacy and safety analyses were performed on all participants who received at least one dose of study medication. The rate of HBeAg seroconversion and undetectable HBV-DNA were evaluated after 52 weeks of therapy. At the end of treatment, 11 of 30（36.7%） patients receiving combination therapy achieved HBeAg seroconversion versus 8 of 31（25.8%） in the monotherapy group（P=0.36）. In contrast, the percentage of patients with undetectable serum HBV DNA was significantly higher in the combination group than in the monotherapy group（76.7% vs. 29.0%, P〈0.001）. Thyroid dysfunction was more frequent in the combination group than in the monotherapy group（P〈0.05）. In HBeAg-positive CHB, combination of Peg-IFN alpha-2b and adefovir for 52 weeks resulted, at the end of treatment, in a higher virological response but without significant impact on the rate of HBeAg seroconversion and possibly an adverse effect on thyroid function.展开更多

METHODS： Sixty-one patients were divided into three groups. Forty-two patients who had not received a nucleoside analogue were randomized into two groups： group A （n = 21） received LVD 100 mg/d and group B （n -- 21） received ETV 0.5 mg/d. The remaing 19 patients treated with LVD （n = 19）, who switched to ETV 1.0 mg/d served as group C. All patients were treated for 48 wk. HBV DNA levels were measured with polimerase- chain-reaction （PCR） analysis. Liver function tests, HBV serology and safety assessments were also conducted. RESULTS： Significantly more patients in group B （52.1% and 71.4%） had undetectable HBV DNA levels than in groups A （35.8% and 38%; P 〈 0.0001） and C （10.6% and 21.1%, P 〈 0.0001） at wk 24 and 48, respectively. At wk 48, ALT levels were normalized in more patients in group B （85.7%） than in groups A （76.2%） and C （74%）. CONCLUSION： ETV had a significantly higher response rate than LVD in patients with HBeAg-positive CriB who had not previously received a nucleoside analogue; ETV can effectively inhibit the replication of HBV DNA and normalize the levels of ALT in refractory CriB patients treated with LVD; and ETV is safe in clinical application.展开更多

METHODS:We conducted a literature search using PubMed, MEDLINE, EMBASE, the China National Knowledge Infrastructure, the VIP database, the Wanfang database and the Cochrane Controlled Trial Register for all relevant articles published before April 1, 2012. Randomized controlled trials (RCTs) comparing LDT with ETV for treatment of HBeAg-positive chronic hepatitis B were included. The data was analyzed with Review Manager Software 5.0. We used relative risk (RR) as an effect measure, and reported its 95% CI. Meta-analysis was performed using either a fixedeffect or random-effect model, based on the absence or presence of significant heterogeneity. Two reviewers assessed the risk of bias and extracted data indepen- dently and in duplicate. The analysis was executed using the main outcome parameters including hepatitis B virus (HBV) DNA undetectability, alanine aminotransferase (ALT) normalization, HBeAg loss, HBeAg seroconversion, drug-resistance, and adverse reactions. Meta-analysis of the included trials and subgroup analyses were conducted to examine the association between pre-specified characteristics with the therapeutic effects of the two agents. RESULTS:Thirteen eligible trials (3925 patients in total) were included and evaluated for methodological quality and heterogeneity. In various treatment durations of 4 wk, 8 wk, 12 wk, 24 wk, 36 wk, 48 wk, 52 wk, 60 wk and 72 wk, the rates of HBV DNA undetectability and ALT normalization in the two groups were similar, without statistical significance. At 4 wk and 8 wk of the treatment, no statistical differences were found in the rate of HBeAg loss between the two groups, while the rate in the LDT group was higher than in the ETV group at 12 wk, 24 wk, 48 wk and 52 wk, respectively (RR 2.28, 95% CI 1.16, 7.03, P = 0.02; RR 1.45, 95% CI 1.16, 1.82, P = 0.001; RR 1.45, 95% CI 1.11, 1.89, P = 0.006; and RR 1.86, 95% CI 1.04, 3.32, P = 0.04). At 4 wk, 8 wk, 60 wk and 72 wk of the treatment, there were no significant differences in the rate of HBeAg seroconversion between the two groups, while at 12 wk, 24 wk, 48 wk and 52 wk, the rate in the LDT group was higher than in the ETV group (RR 2.10, 95% CI 1.36, 3.24, P = 0.0008; RR 1.71, 95% CI 1.29, 2.28, P = 0.0002; RR 1.86, 95% CI 1.36, 2.54, P < 0.0001; and RR 1.87, 95% CI 1.21, 2.90, P = 0.005). The rate of drug-resistance was higher in the LDT group than in the ETV group (RR 3.76, 95% CI 1.28, 11.01, P = 0.02). In addition, no severe adverse drug reactions were observed in the two groups. And the rate of increased creatine kinase in the LDT group was higher than in the ETV group (RR 5.58, 95% CI 2.22, 13.98, P = 0.0002). CONCLUSION:LDT and ETV have similar virological and biomedical responses, and both are safe and well tolerated. However, LDT has better serological response and higher drug-resistance.展开更多

The rate of HBe Ag seroconversion was determined after therapy, and the factors influencing HBe Ag seroconversion were analyzed.Results The rate of HBe Ag seroconversion was 30.00% at the end of treatment. The rate of HBe Ag seroconversion gradually increased with the elevation of liver inflammatory activity(χ2 = 9.170, P = 0.027). But liver fibrosis has little correlation with the rate of HBeA g seroconversion(χ2 = 5.917, P = 0.116). Except HBeA g, other baseline indexes including gender, age, serum ALT and serum HBV DNA 1evels had no statistical difference between the patients with HBe Ag seroconversion and the patients without HBe Ag seroconversion. By binary logistic regression analysis, liver inflammation and HBeA g were influencing factors for HBeA g seroconversion. Conclusions Pegylated interferon α therapy induces a higher rate of HBeA g seroconversion in HBeA g-positive chronic hepatitis B patients with severe liver inflammation, so the liver biopsies should be performed in time.展开更多

文摘AIM: To evaluate the predictive effect of baseline hepatitis B surface antigen (HBsAg) on response to pegylated interferon (PEG-IFN)-α2b in hepatitis B e antigen (HBeAg)-positive chronic hepatitis B (CHB) patients.
文摘Currently available monotherapies of oral nucleoside/nucleotide analogs or interferon are unable to achieve a sustained and effective response in most of patients with chronic hepatitis B（CHB）. The objective of the present study was to compare the efficacy and safety of pegylated interferon（Peg-IFN） alpha-2b plus adefovir dipivoxil combination therapy versus Peg-IFN alpha-2b alone. Sixty-one HBeAg-positive chronic hepatitis B patients were randomized to receive Peg-IFN alpha-2b alone（1.5 μg/kg once weekly） or Peg-IFN alpha-2b plus adefovir（10 mg daily） for up to 52 weeks. Efficacy and safety analyses were performed on all participants who received at least one dose of study medication. The rate of HBeAg seroconversion and undetectable HBV-DNA were evaluated after 52 weeks of therapy. At the end of treatment, 11 of 30（36.7%） patients receiving combination therapy achieved HBeAg seroconversion versus 8 of 31（25.8%） in the monotherapy group（P=0.36）. In contrast, the percentage of patients with undetectable serum HBV DNA was significantly higher in the combination group than in the monotherapy group（76.7% vs. 29.0%, P〈0.001）. Thyroid dysfunction was more frequent in the combination group than in the monotherapy group（P〈0.05）. In HBeAg-positive CHB, combination of Peg-IFN alpha-2b and adefovir for 52 weeks resulted, at the end of treatment, in a higher virological response but without significant impact on the rate of HBeAg seroconversion and possibly an adverse effect on thyroid function.
文摘To evaluate the efficacy and safety of entecavir （ETV） in hepatitis Be antigen （HBeAg）-positive chronic hepatitis B （CriB） patients who had not received a nucleoside analogue and who had failed in lamivudine （LVD） therapy. METHODS： Sixty-one patients were divided into three groups. Forty-two patients who had not received a nucleoside analogue were randomized into two groups： group A （n = 21） received LVD 100 mg/d and group B （n -- 21） received ETV 0.5 mg/d. The remaing 19 patients treated with LVD （n = 19）, who switched to ETV 1.0 mg/d served as group C. All patients were treated for 48 wk. HBV DNA levels were measured with polimerase- chain-reaction （PCR） analysis. Liver function tests, HBV serology and safety assessments were also conducted. RESULTS： Significantly more patients in group B （52.1% and 71.4%） had undetectable HBV DNA levels than in groups A （35.8% and 38%; P 〈 0.0001） and C （10.6% and 21.1%, P 〈 0.0001） at wk 24 and 48, respectively. At wk 48, ALT levels were normalized in more patients in group B （85.7%） than in groups A （76.2%） and C （74%）. CONCLUSION： ETV had a significantly higher response rate than LVD in patients with HBeAg-positive CriB who had not previously received a nucleoside analogue; ETV can effectively inhibit the replication of HBV DNA and normalize the levels of ALT in refractory CriB patients treated with LVD; and ETV is safe in clinical application.

文摘AIM:To compare the effects of telbivudine (LDT) and entecavir (ETV) in treatment of hepatitis B e antigen (HBeAg)-positive chronic hepatitis B by meta-analysis. METHODS:We conducted a literature search using PubMed, MEDLINE, EMBASE, the China National Knowledge Infrastructure, the VIP database, the Wanfang database and the Cochrane Controlled Trial Register for all relevant articles published before April 1, 2012. Randomized controlled trials (RCTs) comparing LDT with ETV for treatment of HBeAg-positive chronic hepatitis B were included. The data was analyzed with Review Manager Software 5.0. We used relative risk (RR) as an effect measure, and reported its 95% CI. Meta-analysis was performed using either a fixedeffect or random-effect model, based on the absence or presence of significant heterogeneity. Two reviewers assessed the risk of bias and extracted data indepen- dently and in duplicate. The analysis was executed using the main outcome parameters including hepatitis B virus (HBV) DNA undetectability, alanine aminotransferase (ALT) normalization, HBeAg loss, HBeAg seroconversion, drug-resistance, and adverse reactions. Meta-analysis of the included trials and subgroup analyses were conducted to examine the association between pre-specified characteristics with the therapeutic effects of the two agents. RESULTS:Thirteen eligible trials (3925 patients in total) were included and evaluated for methodological quality and heterogeneity. In various treatment durations of 4 wk, 8 wk, 12 wk, 24 wk, 36 wk, 48 wk, 52 wk, 60 wk and 72 wk, the rates of HBV DNA undetectability and ALT normalization in the two groups were similar, without statistical significance. At 4 wk and 8 wk of the treatment, no statistical differences were found in the rate of HBeAg loss between the two groups, while the rate in the LDT group was higher than in the ETV group at 12 wk, 24 wk, 48 wk and 52 wk, respectively (RR 2.28, 95% CI 1.16, 7.03, P = 0.02; RR 1.45, 95% CI 1.16, 1.82, P = 0.001; RR 1.45, 95% CI 1.11, 1.89, P = 0.006; and RR 1.86, 95% CI 1.04, 3.32, P = 0.04). At 4 wk, 8 wk, 60 wk and 72 wk of the treatment, there were no significant differences in the rate of HBeAg seroconversion between the two groups, while at 12 wk, 24 wk, 48 wk and 52 wk, the rate in the LDT group was higher than in the ETV group (RR 2.10, 95% CI 1.36, 3.24, P = 0.0008; RR 1.71, 95% CI 1.29, 2.28, P = 0.0002; RR 1.86, 95% CI 1.36, 2.54, P < 0.0001; and RR 1.87, 95% CI 1.21, 2.90, P = 0.005). The rate of drug-resistance was higher in the LDT group than in the ETV group (RR 3.76, 95% CI 1.28, 11.01, P = 0.02). In addition, no severe adverse drug reactions were observed in the two groups. And the rate of increased creatine kinase in the LDT group was higher than in the ETV group (RR 5.58, 95% CI 2.22, 13.98, P = 0.0002). CONCLUSION:LDT and ETV have similar virological and biomedical responses, and both are safe and well tolerated. However, LDT has better serological response and higher drug-resistance.

文摘Objective To investigate the efficiency of pegylated interferon α therapy for patients with HBe Ag-positive chronic hepatitis B(CHB) and explore whether liver histopathological features and other factors might influence HBe Ag seroconversion.Methods Total of 80 HBe Ag-positive CHB patients who received liver puncture were treated with pegylated interferon α once a week for 48 weeks. The rate of HBe Ag seroconversion was determined after therapy, and the factors influencing HBe Ag seroconversion were analyzed.Results The rate of HBe Ag seroconversion was 30.00% at the end of treatment. The rate of HBe Ag seroconversion gradually increased with the elevation of liver inflammatory activity(χ2 = 9.170, P = 0.027). But liver fibrosis has little correlation with the rate of HBeA g seroconversion(χ2 = 5.917, P = 0.116). Except HBeA g, other baseline indexes including gender, age, serum ALT and serum HBV DNA 1evels had no statistical difference between the patients with HBe Ag seroconversion and the patients without HBe Ag seroconversion. By binary logistic regression analysis, liver inflammation and HBeA g were influencing factors for HBeA g seroconversion. Conclusions Pegylated interferon α therapy induces a higher rate of HBeA g seroconversion in HBeA g-positive chronic hepatitis B patients with severe liver inflammation, so the liver biopsies should be performed in time.

文摘In this editorial,we comment on the article by Meng et al.Chronic hepatitis B(CHB)is a significant global health problem,particularly in developing countries.Hepatitis B virus(HBV)infection is one of the most important risk factors for cirrhosis and hepatocellular carcinoma.Prevention and treatment of HBV are key measures to reduce complications.At present,drug therapy can effectively control virus replication and slow disease progression,but completely eliminating the virus remains a challenge.Anti-HBV treatment is a long-term process,and there are many kinds of antiviral drugs with different mechanisms of action,it is essential to evaluate the safety and efficacy of these drugs to reduce side effects and improve patients’compliance.We will summarize the current status of CHB drug treatment,hoping to provide a reference for the selection of clinical antiviral drugs.

文摘BACKGROUND C-X-C chemokine receptor type 5(CXCR5)^(+)CD8^(+)T cells represent a unique immune subset with dual roles,functioning as cytotoxic cells in persistent viral infections while promoting B cell responses.Despite their importance,the specific role of CXCR5^(+)CD8^(+)T cells in chronic hepatitis B(CHB),particularly during interferon-alpha(IFN-α)treatment,is not fully understood.This study aims to elucidate the relationship between CXCR5^(+)CD8^(+)T cells and sustained serologic response(SR)in patients undergoing 48 weeks of pegylated IFN-α(peg-IFN-α)treatment for CHB.AIM To elucidate the relationship between CXCR5^(+)CD8^(+)T cells and sustained SR in patients undergoing 48 weeks of peg-IFN-αtreatment for CHB.METHODS This study enrolled 60 patients with hepatitis Be antigen(HBeAg)-positive CHB undergoing 48 weeks of peg-IFN-αtreatment.Participants were assessed for eligibility based on criteria such as persistent HBsAg-positive status for at least six months,HBeAb-negative,hepatitis B virus DNA levels exceeding 2×10^(4) copies/mL,and alanine aminotransferase(ALT)levels between 2 and 10 times the upper limit of normal.Blood samples were collected at baseline and at weeks 12,24,48,and a 24-week treatment-free follow-up(week 72)to measure serum interleukin(IL)-21 concentration via ELISA and to analyze CXCR5 and programmed death-ligand 1(PD-L1)expression on CD8^(+)T cells by flow cytometry,CXCR5 is a chemokine receptor that directs immune cells to specific tissues,while PD-L1 is a protein that regulates immune responses by inhibiting T cell activity.RESULTS Patients with CHB exhibited significantly lower levels of circulating CXCR5^(+)CD8^(+)T cells compared to healthy controls(P<0.01).Notably,CXCR5^(+)CD8^(+)T cells were prominently expressed in patients who achieved sustained SR compared to non-SR(NSR).A significant correlation was observed between CXCR5 and PD-L1 expression(r=-0.189,P=0.002).However,there was no significant correlation between serum IL-21 levels and CXCR5+CD8+lymphocytes(r=-0.03,P=0.625)or serum ALT levels(r=0.026,P=0.678).CONCLUSION The enhanced expression of CXCR5^(+)CD8^(+)T cells in patients achieving HBeAg seroconversion during IFN-αtreatment suggests that these cells play a crucial role in antiviral immune responses against hepatitis B.This study highlights the potential of CXCR5^(+)CD8^(+)T cells as immune regulators in CHB,which may inform future therapeutic strategies to optimize antiviral treatments.
文摘BACKGROUND Liver function of chronic hepatitis B(CHB)patients is essentially normal after treatment with antiviral drugs.In rare cases,persistently abnormally elevatedα-fetoprotein(AFP)is seen in CHB patients following long-term antiviral treatment.However,in the absence of imaging evidence of liver cancer,a reasonable expla-nation for this phenomenon is still lacking.AIM To explore the causes of abnormal AFP in patients with CHB who were not diag-nosed with liver cancer.METHODS From November 2019 to May 2023,15 patients with CHB after antiviral treatment and elevated AFP were selected.Clinical data and quality indicators related to laboratory testing,imaging data,and pathological data were obtained through inpatient medical records.RESULTS All patients had increased AFP and significantly elevated IgG.Cancer was excluded by imaging examination.Only four patients had elevated alanine ami-notransferase,10 had elevated aspartate aminotransferase,nine had elevated total bilirubin,and two had antinuclear antibodies.The liver biopsy and histopatho-logical examination indicated that 14 patients had rosette,moderate,or higher interfacial inflammation,lymphocyte infiltration,and severe hepatic fibers(11 cases),which was consistent with the pathological features of autoimmune hepa-titis(AIH).After 8-12 week of hormone therapy,the levels of AFP and IgG,and liver function returned to normal(P<0.05).CONCLUSION For patients with CHB and elevated AFP after antiviral treatment,autoimmune hepatitis should be considered.CHB with AIH is clinically insidious and difficult to detect,and prone to progression to cirrhosis.Liver puncture pathological examination should be performed when necessary to confirm diagnosis.

文摘BACKGROUND Hepatic steatosis,characterized by fat accumulation in hepatocytes,can result from metabolic dysfunction-associated steatotic liver disease(MASLD),infections,alcoholism,chemotherapy,and toxins.MASLD is diagnosed via imaging or biopsy with metabolic criteria and may progress to metabolic dysfunction–asso-ciated steatohepatitis,potentially leading to fibrosis,cirrhosis,or cancer.The coexistence of hepatic steatosis with chronic hepatitis B(CHB)is mainly related to metabolic factors and increases mortality and cancer risks.As a noninvasive method,attenuation imaging(ATI)shows promise in quantifying liver fat,demonstrating strong correlation with liver biopsy.AIM To investigate the disparity of ATI for assessing biopsy-based hepatic steatosis in CHB patients and MASLD patients.METHODS The study enrolled 249 patients who underwent both ATI and liver biopsy,including 78 with CHB and 171 with MASLD.Hepatic steatosis was classified into grades S0 to S3 according to the proportion of fat cells present.Liver fibrosis was staged from 0 to 4 according to the meta-analysis of histological data in viral hepatitis scoring system.The diagnostic performance of attenuation coefficient(AC)values across different groups was compared for each grade of steatosis.Factors associated with the AC values were determined through linear regression analysis.A multivariate logistic regression model was established to predict≥S2 within the MASLD group.RESULTS In both the CHB and the MASLD groups,AC values increased significantly with higher steatosis grade(P<0.001).In the CHB group,the areas under the curve(AUCs)of AC for predicting steatosis grades≥S1,≥S2 and S3 were 0.918,0.960 and 0.987,respectively.In contrast,the MASLD group showed AUCs of 0.836,0.774,and 0.688 for the same steatosis grades.The diagnostic performance of AC for detecting≥S2 and S3 indicated significant differences between the two groups(both P<0.001).Multivariate linear regression analysis identified body mass index,trigly-cerides,and steatosis grade as significant factors for AC.When the steatosis grade is≥S2,it can progress to more serious liver conditions.A clinical model integrating blood biochemical parameters and AC was developed in the MASLD group to enhance the prediction of≥S2,achieving an AUC of 0.848.CONCLUSION The AC could effectively discriminate the degree of steatosis in both the CHB and MASLD groups.In the MASLD group,when combined with blood biochemical parameters,AC exhibited better predictive ability for moderate to severe steatosis.
文摘BACKGROUND Chronic hepatitis B often progresses silently toward hepatocellular carcinoma(HCC),a leading cause of mortality worldwide.Early detection of HCC is crucial,yet challenging.AIM To investigate the role of dynamic changes in alkaline phosphatase to prealbumin ratio(APR)in hepatitis B progression to HCC.METHODS Data from 4843 patients with hepatitis B(January 2015 to January 2024)were analyzed.HCC incidence rates in males and females were compared using the log-rank test.Data were evaluated using Kaplan–Meier analysis.The Linear Mixed-Effects Model was applied to track the fluctuation of APR levels over time.Furthermore,Joint Modeling of Longitudinal and Survival data was employed to investigate the temporal relationship between APR and HCC risk.RESULTS The incidence of HCC was higher in males.To ensure the model’s normality assumption,this study applied a logarithmic transformation to APR,yielding ratio.Ratio levels were higher in females(t=5.26,P<0.01).A 1-unit increase in ratio correlated with a 2.005-fold higher risk of HCC in males(95%CI:1.653-2.431)and a 2.273-fold higher risk in females(95%CI:1.620-3.190).CONCLUSION Males are more prone to HCC,while females have higher APR levels.Despite no baseline APR link,rising APR indicates a higher HCC risk.

文摘Background and Aims:Few previous studies have reported on a combination response(hepatitis B virus(HBV)DNA undetected,alanine aminotransferase normalization and hepatitis B e antigen(HBeAg)seroconversion)following nucleos(t)ide analogue(NAs)long-term therapy in patients with chronic hepatitis B(CHB).This study aimed to investigate the combination response on long-term NAs therapy in patients with HBeAg-positive CHB and to determine whether prolonged therapy is beneficial for combination response,particularly in optimal patients(baseline alanine aminotransferase level≥5 upper limit of normal and HBV DNA level<10^(9) copies/mL).Methods:In total,280 HBeAg-positive CHB patients were enrolled in this study.Among them,190 were treated with entecavir and 90 were treated with telbivudine.Results:The cumulative rates of combination response in the total number of patients were 8.6%at 1 year,13.2%at 2 years,19.1%at 3 years,24.2%at 4 years and 26.0%at 5 years.In optimal patients,the cumulative rate of combination response was significantly higher than that in the non-optimal patients at 3 years(p=0.043);the trend of the cumulative rate was not strong at the later time.Interestingly,in optimal patients,combination response mainly occurred in the first 3 years.Multivariate analysis identified HBeAg/anti-HBe seroconversion at 1 year as the only factor for combination response in optimal patients(hazard ratio:16.321;p=0.000).During the 3 years,the proportion with aspartate aminotransaminase to platelet ratio index≤0.5 increased from 15.6%at baseline to 71.3%at year 3.Conclusions:Upgrading the rate of combination response is limited by prolonging the treatment duration of NAs from 3 years to 5 years in HBeAg-positive CHB patients;a new switch treatment strategy modification should be considered,particularly in optimal patients.

文摘Background and Aims:Only a small percentage of chronic hepatitis B(CHB)patients effectively respond to treatment with pegylated-interferon alpha(PegIFNα)or nucleos(t)ide analogues(NUCs).We aimed to detect the correlations of complement regulators-associated single-nucleotide polymorphisms(SNPs)with treatment response of hepatitis B e antigen(HBeAg)-positive CHB patients.Methods:A total of 1,763 HBeAg-positive CHB patients were enrolled,894 received PegIFNαfor at least 48 weeks and were followed up for 24 weeks,and 869 received NUCs for 104 weeks.For each patient,nine SNPs in genes encoding for complement regulators were determined and genotyped.To assess the cumulative effect of numerous SNPs,a polygenic score(PGS)was utilized.The correlations of SNPs and PGS with the levels of combined response(CR)and hepatitis B s antigen(HBsAg)loss were also investigated.Results:In PegIFNα-treated patients,an intronic SNP of CD55,rs28371597,was strongly related to CR,and the CR rate in rs28371597_GG genotype carriers was only approximately half that of rs28371597_GT/TT genotype carriers(20.29%vs.37.10%,p=2.00×10^(−3)).A PGS incorporating CD55_rs28371597 and two additional SNPs,CFB_rs12614 and STAT4_rs7574865,which had been considered as predictors for PegIFNαtreatment response before,was strongly correlated with the levels of CR(ptrend=7.94×10^(−6))and HBsAg loss(p-trend=9.40×10^(−3))in PegIFNα-treated patients.In NUCs-treated individuals,however,none of the nine SNPs were shown to be significantly linked to CHB treatment response.Conclusions:CD55_rs28371597 is a promising biomarker for predicting CHB patients’responsiveness to PegIFNαtherapy.The updated PGS may be used for optimizing CHB treatment.
文摘Objective:To evaluate the efficacy of entecavir and adefovir dipivoxil on HBeAg-positive nucleos(t)ide-naive patients with chronic hepatitis B with the method of Meta analysis.Methods:We searched PUBMED,EMBASE,CNKI (China National Knowledge Infrastructure),the Cochrane Central Register of Controlled Trials and the Cochrane Database of Systematic Reviews with reference to all data documented before May 2010.The dosage of entecavir and adefovir dipivoxil was 0.5 mg/d and 10 mg/d,respectively.Heterogeneity was examined by Chi-square test,the relative risk calculated and forest plot drawn.Rates of undetected serum HBV DNA,serum alanine aminotransferase (ALT) normalization,HBeAg clearance,HBeAg seroconversion and adverse effect occurrence were analyzed.Results:Six articles were included,which fit well in with this study.Meta analysis showed that the rate of undetected serum HBV DNA(P=0.000 2 at week 12,P=0.002 at week 48)and that of serum ALT normalization(P=0.04 at week 12,P=0.008 at week 48)in the entecavir group were higher than those in the adefovir dipivoxil group.However,no statistic significance existed between the two groups in the rate of HBeAg clearance (P=0.17),the rate of HBeAg seroconversion(P=0.53)or the rate of adverse effect occurrence(P=0.92)at week 48.Conclusion:Entecavir was superior to adefovir dipivoxil in decreasing serum HBV DNA and normalizing serum ALT in the HBeAg-positive nucleos(t)ide-naive patients with chronic hepatitis B.
文摘Due to sedentary lifestyle and rising prevalence of obesity,patients with general population and those who are infected with chronic hepatitis B are found to have metabolic dysfunction associated steatotic liver disease(MASLD).Both chronic hepatitis B virus(HBV)infection and MASLD can damage hepatocytes in their own way,but concomitant HBV-MASLD has its own clinical implications.Cherry on top is the presence of diabetes mellitus,hypertension or obesity which added more chances of unfavorable outcomes in these patients.In this article,we co-mment on the article by Wang et al published in the recent issue.This article provides a comprehensive overview of the complex interaction between HBV-MASLD,HBV alone and MASLD alone patients.We discuss key findings from recent studies,including the promising outcomes observed in patients with concurrent HBV and MASLD,warrants further research.The insights presented here offer renewed understanding of this complex interaction.

文摘BACKGROUND Models for predicting hepatitis B e antigen(HBeAg)seroconversion in patients with HBeAg-positive chronic hepatitis B(CHB)after nucleos(t)ide analog treatment are rare.AIM To establish a simple scoring model based on a response-guided therapy(RGT)strategy for predicting HBeAg seroconversion and hepatitis B surface antigen(HBsAg)clearance.METHODS In this study,75 previously treated patients with HBeAg-positive CHB underwent a 52-week peginterferon-alfa(PEG-IFNα)treatment and a 24-wk follow-up.Logistic regression analysis was used to assess parameters at baseline,week 12,and week 24 to predict HBeAg seroconversion at 24 wk post-treatment.The two best predictors at each time point were used to establish a prediction model for PEG-IFNαtherapy efficacy.Parameters at each time point that met the corresponding optimal cutoff thresholds were scored as 1 or 0.RESULTS The two most meaningful predictors were HBsAg≤1000 IU/mL and HBeAg≤3 S/CO at baseline,HBsAg≤600 IU/mL and HBeAg≤3 S/CO at week 12,and HBsAg≤300 IU/mL and HBeAg≤2 S/CO at week 24.With a total score of 0 vs 2 at baseline,week 12,and week 24,the response rates were 23.8%,15.2%,and 11.1%vs 81.8%,80.0%,and 82.4%,respectively,and the HBsAg clearance rates were 2.4%,3.0%,and 0.0%,vs 54.5%,40.0%,and 41.2%,respectively.CONCLUSION We successfully established a predictive model and diagnosis-treatment process using the RGT strategy to predict HBeAg and HBsAg seroconversion in patients with HBeAg-positive CHB undergoing PEG-IFNαtherapy.
