AIM: To determine the therapeutic effect of lamivu- dine in late pregnancy for the interruption of motherto-child transmission (MTCT) of hepatitis B virus (HBV). METHODS: Studies were identified by searching available databases up to January 2011. Inclusive criteria were HBV-carrier mothers who had been involved in randomized controlled clinical trials (RCTs) with lamivudine treatment in late pregnancy, and newborns or infants whose serum hepatitis B surface antigen (HBsAg), hepatitis B e antigen (HBeAg) or HBV DNA had been documented. The relative risks (RRs) for inerruption of MTCT as indicated by HBsAg, HBV DNA or HBeAg of newborns or infants were calculated with 95% confidence interval (CI) to estimate the efficacy of lamivudine treatment. RESULTS: Fifteen RCTs including 1693 HBV-carrier mothers were included in this meta-analysis. The overall RR was 0.43 (95% CI, 0.25-0.76; 8 RCTs; Phet- erogeneity= 0.04) and 0.33 (95% CI, 0.23-0.47; 6 RCTs; Pheterogeneity = 0.93) indicated by newborn HBsAg or HBV DNA. The RR was 0.33 (95% CI, 0.21-0.50; 6 RCTs; Pheterogeneity = 0.46) and 0.32 (95% CI, 0.20-0.50; 4 RCTs; Pheterogeneity = 0.33) indicated by serum HBsAg or HBV DNA of infants 6-12 mo after birth. The RR (lamivudine vs hepatitis B immunoglobulin) was 0.27 (95% CI, 0.16-0.46; 5 RCTs; Pheterogeneity = 0.94) and 0.24 (95% CI, 0.07-0.79; 3 RCTs; Pheterogeneity = 0.60) indicated by newborn HBsAg or HBV DNA, respectively. In the mothers with viral load 〈 106 copies/mL after lamivudine treatment, the efficacy (RR, 95% CI) was 0.33, 0.21-0.53 (5 RCTs; Pheterogeneity = 0.82) for the interruption of MTCT, however, this value was not significant if maternal viral load was 〉 106 copies/mL after lamivudine treatment (P = 0.45, 2 RCTs), as indicated by newborn serum HBsAg. The RR (lamivudine initiated from 28 wk of gestation vs control) was 0.34 (95% CI, 0.22-0.52; 7 RCTs; Pheterogeneity = 0.92) and 0.33 (95% CI, 0.22-0.50; 5 RCTs; Pheterogeneity = 0.86) indicated by newborn HBsAg or HBV DNA. The incidence of adverse effects of lamivudine was not higher in the mothers than in controls (P = 0.97). Only one study reported side effects of lamivudine in newborns. CONCLUSION: Lamivudine treatment in HBV carrier- mothers from 28 wk of gestation may interrupt MTCT of HBV efficiently. Lamivudine is safe and more efficient than hepatitis B immunoglobulin in interrupting MTCT. HBV MTCT might be interrupted efficiently if maternal viral load is reduced to 〈 106 copies/mL by lamivudine treatment. 展开更多

AIM:To compare the effects of entecavir(ETV)and lamivudine(LAM)for the treatment of hepatitis B decompensated cirrhosis using a meta-analysis.METHODS:We conducted a literature search for all eligible studies published prior to May 30,2013 using PUBMED,MEDLINE,EMBASE,the China National Knowledge Infrastructure(CNKI),the VIP database,the Wanfang database and the Cochrane Controlled Trial Register.Randomized controlled trials(RCTs)comparing ETV with LAM for the treatment of hepatitis B decompensated cirrhosis were included.The data were analyzed with Review Manager Software 5.0.2.We used RR as an effect measure,and reported its95%CI.The meta-analysis was performed using either a fixed-effect or random-effect model,based on the absence or presence of significant heterogeneity.Two reviewers assessed the risk of bias and extracted data independently and in duplicate.The analysis was executed using the main outcome parameters including hepatitis B virus(HBV)DNA undetectability,HBV DNA level,hepatitis B e antigen(HBeAg)seroconversion,alanine aminotransferase(ALT)level,albumin level,total bilirubin(TBIL)level,prothrombin time activity(PTA)level,Child-Turcotte-Pugh(CTP)score,mortality,drugresistance,and adverse reactions.Meta-analysis of the included trials and subgroup analyses were conducted to examine the association between pre-specified characteristics and the therapeutic effects of the two agents.RESULTS:Thirteen eligible trials(873 patients in total)were included and evaluated for methodological quality and heterogeneity.Of these studies,all had baseline comparability,12 of them reported baseline values of the two treatment groups in detail.Following various treatment durations(12,24,36,48 and>48 wk),both ETV and LAM significantly reduced HBV DNA level,however,reductions were greater in the ETV group(MD=-0.66,95%CI:-0.83-0.50,P<0.00001),(MD=-0.93,95%CI:-1.36-0.51,P<0.0001),(MD=-1.4,95%CI:-1.78-1.01,P<0.00001),(MD=-1.18,95%CI:-1.90-0.46,P=0.001),(MD=-0.14,95%CI:-0.17-0.11,P<0.00001,respectively).At 12,24 and48 wk of treatment,ETV had a significant effect on the rate of HBV DNA undetectability(RR=1.55,95%CI:1.22-1.99,P=0.0004),(RR=1.25,95%CI:1.13-1.38,P<0.0001),(RR=1.2,95%CI:1.10-1.32,P<0.0001,respectively).Although HBeAg seroconversion in the ETV group was more pronounced than that in the LAM group at 24 wk(27.90%vs 26.19%)and 48 wk(31.52%vs 25.00%)of treatment,there was no statistically significant difference between them(RR=1.49,95%CI:0.98-2.28,P=0.07),(RR=1.27,95%CI:0.98-1.65,P=0.07,respectively).Following various treatment durations,both the ETV group and the LAM group showed significantly improved liver function(ALT,AIB,TBIL,PTA and CTP levels)and reduced mortality(ETV 6.37%,LAM 7.89%).The effects in the ETV group(0.33%)were statistically lower than those in the LAM group(14.33%)regarding the rate of drug-resistance(RR=0.1,95%CI:0.04-0.24,P≤0.00001).In addition,no severe adverse reactions were observed in the two treatment groups.CONCLUSION:ETV and LAM significantly improved liver function and reduced mortality.Both drugs produced similar serological responses,and were safe and well tolerated.However,ETV resulted in a better virological response and lower drug-resistance,but is more expensive. 展开更多

AIM:To investigate the short-term and long-term efficacy of entecavir versus lamivudine in patients with spontaneous reactivation of hepatitis B presenting as acute-on-chronic liver failure(ACLF).METHODS:This was a single center,prospective cohort study.Eligible,consecutive hospitalized patients received either entecavir 0.5 mg/d or lamivudine 100mg/d.All patients were given standard comprehensive internal medicine.The primary endpoint was survival rate at day 60,and secondary endpoints were reduction in hepatitis B virus(HBV)DNA and alanine aminotransferase(ALT)levels,and improvement in Child-Turcotte-Pugh(CTP)and model for end-stage liver disease(MELD)scores at day 60 and survival rate at week 52.RESULTS:One hundred and nineteen eligible subjects were recruited from 176 patients with severe acute exacerbation of chronic hepatitis B:65 were included in the entecavir group and 54 in the lamivudine group(full analysis set).No significant differences were found in patient baseline clinical parameters.At day 60,entecavir did not improve the probability of survival(P=0.066),despite resulting in faster virological suppression(P<0.001),higher rates of virological response(P<0.05)and greater reductions in the CTP and MELD scores(all P<0.05)than lamivudine.Intriguingly,at week 52,the probability of survival was higher in the entecavir group than in the lamivudine group[42/65(64.6%)vs 26/54(48.1%),respectively;P=0.038].The pretreatment MELD score(B,1.357;95%Cl:2.138-7.062;P=0.000)and virological response at day30(B,1.556;95%Cl:1.811-12.411;P=0.002),were found to be good predictors for 52-wk survival.CONCLUSION:Entecavir significantly reduced HBV DNA levels,decreased the CTP and MELD scores,and thereby improved the long-term survival rate in patients with spontaneous reactivation of hepatitis B presenting as ACLF. 展开更多

AIM: To identify the factors associated with virologic breakthrough and to select a subgroup of patients who respond well to lamivudine without developing virologic breakthrough (VBT). METHODS: Of 79 patients who had received lamivudine therapy for 9-57 mo, 34 were HBeAg-positive and 45 were HBeAg-negative, 24 developed virologic breakthrough and 55 did not. Clinical and virologic factors were compared between the two groups. RESULTS: The median duration of therapy was 25 (9-57) mo. Virologic breakthrough was defined as a > 1 log HBV DNA increase following initial suppression. When several factors, including gender, duration of infection, baseline HBV DNA, and baseline ALT in HBeAg-positive chronic hepatitis patients were analyzed by logistic regression, the most important predictor of virologic breakthrough was the baseline HBV DNA (r2 = 0.12, P < 0.05). When HBeAg-postitive chronic hepatitis patients were divided into two groups by a point of 6.6 log HBV DNA, the incidence of virologic breakthough between two groups was significantly different. CONCLUSION: Lamivudine may remain an effective first line therapy for those HBeAg-positive patients with a baseline HBV DNA < 6.6 log10 copies/mL. 展开更多

AIM To demonstrate the non-inferiority(15% non-inferiority limit) of monotherapy with tenofovir disoproxil fumarate(TDF) vs the combination of lamivudine(LAM) plus adefovir dipivoxil(ADV) in the maintenance of virologic response in patients with chronic hepatitis B(CHB) and prior failure with LAM.METHODS This study was a Phase IV prospective, randomized, open, controlled study with 2 parallel groups(TDF and LAM+ADV) of adult patients with hepatitis B e antigen(HBe Ag)-negative CHB, prior failure with LAM, on treatment with LAM+ADV for at least 6 mo, without prior resistance to ADV and with an undetectable viral load at the start of the study, in 14 Spanish hospitals. The follow-up time for each patient was 48 wk after randomization, with quarterly visits in which the viral load, biochemical and serological parameters, adverse effects, adherence to treatment and consumption of hospital resources were analysed.RESULTS Forty-six patients were evaluated [median age: 55.4 years(30.2-75.2); 84.8% male], including 22 patients with TDF and 24 with LAM+ADV. During study development, hepatitis B virus DNA(HBV-DNA) remained undetectable, all patients remained HBe Ag negative, and hepatitis B surface antigen(HBs Ag) positive. Alanine aminotransferase(ALT) values at the end of the study were similar in the 2 groups(25.1± 7.65, TDF vs 24.22 ± 8.38, LAM+ADV, P = 0.646). No significant changes were observed in creatinine or serum phosphorus values in either group. No significant differences between the 2 groups were noted in the identification of adverse effects(AEs)(53.8%, TDF vs 37.5%, LAM+ADV, P = 0.170), and none of the AEs which occurred were serious. Treatment adherence was 95.5% and 83.3% in the TDF and the LAM+ADV groups, respectively(P = 0.488). The costs associated with hospital resource consumption were significantly lower with the TDF treatment than the LAM+ADV treatment(€4943 ± 1059 vs €5811 ± 1538, respectively, P < 0.001).CONCLUSION TDF monotherapy proved to be safe and not inferior to the LAM+ADV combination therapy in maintaining virologic response in patients with CHB and previous LAM failure. In addition, the use of TDF generated a significant savings in hospital costs. 展开更多

BACKGROUND: It has been demonstrated that only a minority of patients with hepatitis B e antigen (HBeAg) negative chronic hepatitis B (CHB) obtain a sustained response after either interferon (IFN) or nucleos (t)ide analogue monotherapy. Therefore, combination therapy of drugs with synergistic antiviral effects was proposed to have a sustained response in these patients. We compared the effect and safety of lamivudine monotherapy and its combination with IFN including conventional interferon (CON-IFN) and pegylated interferon (PEG-IFN) for HBeAg-negative CHB patients. DATA SOURCES: A group of three independent reviewers identified 9 eligible randomized controlled trials through electronic searches (MEDLINE, OVID, EMBASE, the Cochrane Library Clinical Trials Registry, and the Chinese Medical Database), manual searches, and contact with experts. Sustained virological and biochemical responses were defined as primary efficacy measures. We performed quantitative meta-analyses to assess differences between CON-IFN plus lamivudine combination and lamivudine monotherapy groups. RESULTS: No greater sustained virological and biochemical rates were found in patients receiving CON-IFN/lamivudine combination therapy [29.1% vs. 26.7%, odds ratio (OR)=0.98, 95% confidence interval (CI) 0.65-1.50, P=0.94, and 41.8% vs. 40.3%, OR=1.13, 95% CI 0.78-1.65, P=0.51, respectively],though a reduced YMDD mutation rate was achieved in the combination group [8.39% vs. 30.0%, OR=0.16, 95% CI 0.076-0.33, P<0.001]. However, data from one PEG-IFN trial showed greater sustained virological and biochemical rates in patients receiving combination therapy [response rate 19.5% vs. 6.6%, OR=3.42, 95% CI 1.71-6.84, P<0.001 and 60.0% vs. 44.2%, OR=1.88, 95% CI 1.23-2.85, P=0.003, respectively]. CONCLUSIONS: Addition of CON-IFN to lamivudine did not improve treatment efficacy but suppressed YMDD mutation by lamivudine. Combination of PEG-IFN and lamivudine might increase the sustained response, and further clinical trials are needed for confirmation. 展开更多

AIM:To assess the efficacy of tenofovir disoproxil fumarate(TDF) in lamivudine(LAM)-resistant patients with a suboptimal response to LAM plus adefovir(ADV).METHODS:We retrospectively analyzed the efficacy of switching to tenofovir disoproxil fumarate in suboptimal responders to lamivudine plus adefovir.Charts were reviewed for LAM-resistant chronic hepatitis B(CHB) patients who visited the Zhejiang Province People's Hospital and The First Affiliated Hospital,College of Medicine,Zhejiang University,from June 2009 to May 2013.Patients whose serum hepatitis B virus(HBV) DNA remained detectable despite at least 6 mo of LAM plus ADV combination therapy were included.Patients with a suboptimal response to LAM plus ADV were randomized to switch to TDF monotherapy(300 mg/d orally; TDF group) or to continuation with LAM(100 mg/d orally) plus ADV(10 mg/d orally; LAM plus ADV group) and were followed for 48 wk.Serum HBV DNA was determined at baseline and weeks 4,12,24,36,and 48.HBV serological markers and biochemistry were assessed at baseline and weeks 12,24,and 48.Resistance surveillance and side effects were monitored during therapy.RESULTS:Fifty-nine patient were randomized to switch to TDF(n =28) or continuation with LAM plus ADV(n =31).No significant differences were found between the groups at baseline.Prior to TDF therapy,all patients had been exposed to LAM plus ADV for a median of 11 mo(range:6-24 mo).No difference was seen in baseline serum HBV DNA between the two groups [5.13 ± 1.08 log10 copies/m L(TDF) vs 5.04 ± 31.16 log10 copies/m L(LAM +ADV),P =0.639].There was no significant difference in the rates of achieving complete virological response(CVR) at week 4 between the TDF and LAM +ADV groups(17.86% vs 6.45%,P =0.24).The rate of achieving CVR in the TDF and LAM plus ADV groups was 75% vs 16.13% at week 12,82.14% vs 22.58% at week 24,89.29% vs 25.81% at week 36,and 96.43% vs 29.03% at week 48,respectively(P < 0.001).The rate of alanine aminotransferase normalization was significantly higher in the TDF than in the LAM plus ADV group at week 12(75% vs17.86%,P < 0.001),but not at week 24(78.57% vs 54.84%,P =0.097) or 48(89.26% vs 67.74%,P =0.062).Patients were hepatitis B e antigen(HBe Ag) positive at baseline.There was no significant difference in HBe Ag negativity between the TDF and LAM plus ADV groups at week 48(4% vs 0%,P =0.481).There were no drug-related adverse effects at week 48 in either group.CONCLUSION:Switching to TDF monotherapy was superior to continuous add-on therapy in patients with LAM-resistant CHB with a suboptimal response to LAM plus ADV. 展开更多

We describe a 77-year-old woman with chronic hepatitis B who became resistant to lamivudine.She was started on adefovir(10 mg daily)while still continuing lamivudine therapy.Four mo later her liver function improved and serum Hepatitis B virus(HBV)-DNA level became undetectable.Three years after the start of additional adefovir treatment,hepatocellular carcinoma (HCC)was detected and the patient underwent a successful hepa-tectomy.Our findings suggest tha-t the addition of adefovir to ongoing lamivudine therapy cannot completely suppress hepatocarcinogenesis,but is useful for improving liver function in patients with lamivudine-resistant HBV-related cirrhosis,allowing HCC surgery. 展开更多

AIM: To investigate the safety and efficacy of long-term combination therapy with alpha interferon and lamivudine in non-responsive patients with anti-HBe-positive chronic hepatitis B.METHODS: 34 patients received combination treatment (1 month lamivudine, 12 month lamivudine+interferon, 6month lamivudine), 24 received lamivudine (12 months),24 received interferon (12 months). Interferon was administered at 6 MU tiw and lamivudine at 100 mg orally once daily. Patients were followed up for 6 months after treatment.RESULTS: At the end of treatment, HBV DNA negativity rates were 88 % with lamivudine+interferon, 99 % with lamivudine and 55 % with interferon, (P=0.004, combination therapy vs. interferon, and P=0.001 lamivudine vs.interferon), and serum transaminase normalization rates were 84 %, 91% and 53 % (P=0.01 combination therapy vs. interferon, and P=0.012 lamivudine vs. interferon). Six months later, HBV DNA negativity rates were 44 % with lamivudine+interferon, 33 % with lamivudine and 25 % with interferon, and serum transaminase normalization rates were 61%, 42 % and 45 %, respectively, without statistical significance. No YMDD variants were observed with lamivudine+interferon (vs. 12 % with lamivudine). The combination therapy appeared to be safe. CONCLUSION: Although viral clearance and transaminase normalization are slower with long-term lamivudine+interferon than that with lamivudine alone, the combination regimen seems to provide more lasting benefits and to protect against the appearance of YMDD variants. Studies with other regimens regarding sequence and duration are needed. 展开更多

A 53-year-old man was followed since 1998 for HBV-related chronic hepatitis. Serum HBV-DNA was 150 MEq/mL (branched DNA signal amplification assay) and ALT levels fluctuated between 50-200 IU/L with no clinical signs of liver cirrhosis. Lamivudine (100 mg/d) was started in May 2001 and serum HBV-DNA subsequently decreased below undetectable levels. In May 2002, serum HBV-DNA had increased to 410 MEq/mL, along with ALT flare (226 IU/L). The YMDD motif in the DNA polymerase gene had been replaced by YIDD. Lamivudine was continued and ALT spontaneously decreased to the former levels. On Oct 3 the patient presenting with general fatigue, nausea and jaundice was admitted to our hospital. The laboratory data revealed HBV reactivation and liver failure (ALT: 1828 IU/L, total bilirubin: 10 mg/dL, and prothrombin INR: 3.24). For religious reasons, the patient and his family refused blood transfusion, plasma exchange and liver transplantation. The patient died 10 d after admission. The autopsy revealed remarkable liver atrophy. 展开更多

AIM:To investigate and identify prevalent hepatitis B virus(HBV) genotypes and to explore lamivudine-resistant mutations among treated and untreated patients in Jordan.METHODS:A total of 107 cases with chronic hepatitis B were recruited from different medical centers in Jordan.Serological tests were preformed for all cases using a microparticle enzyme immunoassay.HBV Genotyping was performed for 70 cases using Line probe genotyping assay.The YMDD mutations were explored for 20 cases(4 were lamivudine naive) using the INNO-LiPA HBV DR assay.RESULTS:Genotype D was the only detected genotype.A total of 6 YMDD mutations were detected in 5 treated patients(31%) while one mutation was detected in the naive patients.Seventeen percent of cases were positive for HBeAg and had statistically significant higher levels of serum aminotransferases.CONCLUSION:HBV genotype D appears to be the only circulating type in Jordanian patients.The YMDD mutations were detected in 31% of lamivudine-treated cases with similar patterns to those found in the literature.We also found a relatively low prevalence of HBeAg expression among examined cases(17%).Awareness of these serologic,genotypic and resistance patterns might help in the formulation of management plans and for predicting clinical outcomes.Further larger scale studies are needed to confirm our results and to examine possible associations among clinical,serologic,and genetic patterns of HBV infections in Jordan. 展开更多
