However, some patients continue to have high levels of HBV replication and effective suppression of HBV replication with antiviral agents may potentially decrease hepatic necroinflammation and improve or stabilize liver function. This review was to under stand the efficacy and safety of lamivudine in the treatment of decompensated HBV cirrhosis. DATA SOURCES: An English-language literature search (MEDLINE January 1988-July 2005) was performed, and a total of 52 articles/abstracts relevant to the issue were selected. After review of the selected papers, the meaningful results and conclusions were extracted using scientific crite ria. The papers reviewed pertained mainly to the efficacy and safety profiles of lamivudine treatment for decompensated HBV cirrhosis. RESULTS: The ultimate treatment of decompensated HBV cirrhosis is liver transplantation, but lamivudine treatment may lead to rapid suppression of viral replication and improvement of biochemical and clinical parameters, reduced morbidity and hospitalization for complications of liver disease, increased pre-transplant survival as well as reduced need for transplantation. However, viral resistance can develop after prolonged treatment with lamivudine, and breakthrough hepatitis may be fatal in few patients. Adefovir is effective for lamivudine-resistant HBV mutants. CONCLUSIONS: Antiviral therapy with lamivudine for decompensated HBV cirrhosis can be effective. However, some patients may experience a hepatitis flare with the emergence of YMDD mutants resulting in progressive worsening of liver disease, and should be referred for 'rescue' therapy with other nucleoside/nucleotide analogues such as adefovir dipivoxil.展开更多

The patients were initially treated with LMV and then switched to ADV when LMV resistance developed. Antiviral efficacy was assessed by measuring the following: reduction in serum HBV DNA from baseline, HBV DNA negative conversion (defined as HBV DNA being undectable by the hybridization assay), and HBV DNA response (either HBV DNA level ≤ 10^s copies/mL or a ≥ 2 log10 reduction from baseline HBV DNA level).RESULTS: After two and six months of treatment, HBV DNA reduction was greater with LMV compared to ADV treatment (P = 0.021). HBV DNA negative conversion rates were 64% and 27% after one month of LMV and ADV treatment respectively (P = 0.001). Similarly, HBV DNA response rates were 74% and 51% after two months of LMV and ADV treatment respectively (P = 0.026). The time taken to HBV DNA negative conversion and to HBV DNA response were both delayed in ADV treatment compared with LMV.CONCLUSION: The antiviral efficacy of ADV in LMV-resistant patients is slower and less potent than that with LMV in nucleoside-naive patients during the early course of treatment.展开更多

The patients in the treatment group were given adefovir dipivoxil in combined with lamivudine, while the patients in the control group were given entecavir. After 12-month treatment, the efficacy was evaluated. The liver function, serum virology indicators, and AFP before and after treatment in the two groups were compared. The adverse reactions during the treatment process were recorded.Results: The serum GTP, ALT, AST, and TBIL levels after treatment in the two groups were significantly reduced when compared with before treatment (P<0.05);moreover, ALT and TBIL levels in the treatment group were significantly lower than those in the control group (P<0.05). HBeAg, HBV-DNA, and AFP levels after treatment in the two groups were significantly reduced when compared with before treatment (P<0.05), HBeAg and AFP levels in the treatment group were significantly lower than those in the control group (P<0.05), and the comparison of HBV-DNA between the two groups was not statistically significant (P>0.05). ALT normalization rate and HBeAg negative conversion rate after treatment in the treatment group were significantly higher than those in the control group (P<0.05). The comparison of HBV-DNA negative conversion rate and HBeAg conversion rate between the two groups was not statistically significant (P>0.05). No obvious drug adverse reactions and liver function damage occurred during the treatment process in the two groups. Conclusions:Adefovir dipivoxil in combined with lamivudine can significantly improve the liver function and serum virology indicators in patients with hepatitis B cirrhosis, with antiviral efficacy significantly superior to that by entecavir.展开更多

Of 117 patients,79 received treatment with different nucleoside analogs and 38 served as controls. Bleeding rate,change in variceal grade and non-bleeding duration were analyzed. Multivariate Cox proportional hazard regression was used to identify factors related to esophageal variceal bleeding.antiviral group compared to the control group(29.1%vs 65.8%,P < 0.001). Antiviral therapy was an independent factor related to esophageal bleeding in multivariate analysis(HR = 11.3,P < 0.001). The mean increase in variceal grade per year was lower in the antiviral group(1.0 ± 1.3 vs 1.7 ± 1.2,P = 0.003). Nonbleeding duration in the antiviral group was prolonged in the Kaplan-Meier model. Viral load rebound was observed in 3 cases in the lamivudine group and in 1 case in the adefovir group,all of whom experienced bleeding. Entecavir and adefovir resulted in lower bleeding rates(17.2% and 28.6%,respectively) than the control(P < 0.001 and P = 0.006,respectively),whereas lamivudine(53.3%) did not(P = 0.531).CONCLUSION:Antiviral therapy delays the progression of esophageal varices and reduces bleeding risk in HBV-related cirrhosis,however,high-resistance agents tend to be ineffective for long-term treatment.展开更多

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

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

METHODS: In this retrospective, multi-center trial, 318 Japanese patients with chronic hepatitis B received 100 mg of lamivudine daily for up to 36 (median 21) mo. Virological response was a decline to a serum HBV DNA level less than 3.7 log copies/mL. Virological breakthrough was defined as the reappearance of a serum HBV DNA level to more than 10-fold the minimum during treatment. RESULTS: Lamivudine produced virological response in 86.8% of the 318 patients at 6 mo, in 80.2% of 252 patients at 12 mo, in 69.2% of 133 patients at 24 mo, and in 53.6% of 28 patients at 36 mo. Forward stepwise logistic regression analysis showed an HBV DNA level less than 6.8 log copies/mL (P〈 0.0001), HBeAg negativity (P〈 0.0001), a platelet count of 100×10^9/L or more (P= 0.0162) at baseline, and a decline of the HBV DNA level of more than 3.2 log copies/mL as compared with the baseline level at 3 mo after the start of treatment (P= 0.0003) to be significantly associated with virological response. Among patients with a virological response, virological breakthrough was seen in 5.3% of 19 patients who responded virologically at 1 mo, in 20.7% of 203 patients at 3 mo, in 27.5% of 51 patients at 6 mo, in 33.3% of 12 patients at 9 mo, and in 100% of 3 patients at ≥15 mo. A virological breakthrough was found significantly more often in patients with delayed virological response. CONCLUSION: Lamivudine treatment could suppress serum HBV DNA in most of the tested Japanese patients. Long-term efficacy might be seen in patients without HBeAg at baseline, in the absence of cirrhosis, and in patients with a decline in HBV DNA level soon after the start of treatment.展开更多

ADV was added to LAM at week 48 in Arms A and B, but at week 24 in Arm C. Virological response, YMDD mutations, biochemical response, and liver function were evaluated.RESULTS: Comparison of the three arms demonstrated that early complete virologic response at week 24was associated with maintained viral suppression(undetectable rate of HBV DNA at week 144 was 95.96%, 66.67% and 35.29%, respectively, P = 0.000) and reduced YMDD mutations(mutation rate at week 144 was 0%, 3.23% and 15%, respectively, P = 0.015) after 144 wk treatment. For patients who failed to achieve complete virological response at week 24, switching to combination therapy further decreased HBV DNA level by 1 log10 IU/m L. All three arms obtained biochemical benefits including decline of alanine aminotransferase and elevation of albumin. In patients who developed HBV DNA breakthrough for YMDD mutations, ADV add-on therapy did not induce further multiple drug resistance to LAM or ADV.CONCLUSION: Optimized response-guided add-on therapy of ADV and LAM maintains long-term suppression of HBV DNA and improves liver function in CHB patients with compensated liver cirrhosis.展开更多

A literature review was carried out by framing the study questions. Vaccination in early childhood has been introduced in most countries and reduces the infection rate. Treatment of chronic hepatitis B can control viral replication in most patients today. It reduces risks for progression and may reverse liver fibrosis. The treatment effect on development of hepatocellular carcinoma is less pronounced when cirrhosis is already present. Despite the success of vaccination and therapy chronic hepatitis B remains a problem since many infected patients do not know of their disease. Although all guidelines recommend screening in high risk groups such as migrants, these suggestions have not been implemented. In addition, the performance of hepatocellular cancer surveillance under real-life conditions is poor. The majority of people with chronic hepatitis B live in resource-constrained settings where effective drugs are not available. Despite the success of vaccination and therapy chronic hepatitis B infection remains a major problem since many patients do not know of their disease. The problems in diagnosis andscreening may be overcome by raising awareness, promoting partnerships, and mobilizing resources.展开更多

Since the discovery of interferon-α as a therapeutic option the treatment of hepatitis B has evolved fast and management has become increasingly complicated. The amount of viral replication reflected in the viral load (HBV-DNA) plays an important role in the development of cirrhosis and hepatocellular carcinoma. The current treatment modalities for chronic hepatitis B are immunomodulatory (interferons) and antiviral suppressants (nucleoside and nucleotide analogues) all with their own advantages and limitations. An overview of the treatment efficacy for both immunomodulatory as antiviral compounds is provided in order to provide the clinician insight into the factors influencing treatment outcome. With nucleoside or nucleotide analogues suppression of viral replication by 5-7 log10 is feasible, but not all patients respond to therapy. Known factors influencing treatment outcome are viral load, ALT levels and compliance. Many other factors which might influence treatment are scarcely investigated. Identifying the factors associated with response might result in stopping rules, so treatment could be adapted in an early stage to provide adequate treatment and avoid the development of resistance. The efficacy of compounds for the treatment of mutant virus and the cross-resistance is largely unknown. However, genotypic and phenotypic testing as well as small clinical trials provided some data on efficacy in this population. Discontinuation of nucleoside or nucleotide analogues frequently results in viral relapse; however, some patients have a sustained response. Data on the risk factors for relapse are necessary in order to determine when treatment can be discontinued safely. In conclusion: chronic hepatitis B has become a treatable disease; however, much research is needed to tailor therapy to an individual patient, to predict the sustainability of response and determine the best treatment for those failing treatment.展开更多

Lamivu- dine has been referred as a novel antiviral agent against HBV in HBV cirrhotic patients even in liver transplantation setting. We assessed the prophylatic effect of lamivudine on liver allograft HBV reinfection and clarified the dynamic changes of HBV markers in HBV related decompensated liver cirrhosis after liver transplantation. METHODS: Twenty-five recipients were divided into three groups: HBV active replication group (15 recipients), HBV inactive replication group (7), and control group (3). 100 mg/d lamivudine was administered preoperatively except in the control group. The HBV markers of serial sera and liver biopsy samples of the 25 recipients were evaluated re- gularly with enzyme-linked radioimmunoassay, HBV DNA fluorecent quantitative assay, immunohistochemical stain- ing , labelled streptavidin biotin ( LSAB) and digoxin la- belled HBV DNA hybridization in situ. The dynamic alter- nation of HBV markers under lamivudine prophylaxis was observed. RESULTS: In the HBV active replication group who had received lamivudine 2 weeks before liver transplantation, serum HBV DNA positive converted to negative by 80%. HBsAg of all recipients disappeared after liver transplanta- tion , but corresponding antibodies of HBV appeared within one week after the operation. HBsAb 9/15, HBcAb 13/15 and HBeAb 11/15 appeared and subsided gradually within 24 weeks. HBV DNA in sera was kept negative; HBsAg, HBcAg and HBV DNA hybridization in situ of liver biopsy samples remained negative after use of lamivudine. Ten of the 15 recipients showed clearance of HBV, and per se HBV markers were undetectable both in serum and liver bi- opsy samples between 12 to 44 weeks (24 weeks on ave- rage). The 1-, 2-year survival rates were 83% in this group. Two of the 15 recipients developed HBV allograft reinfection or recurrence of hepatitis 2 years after lamivudi- ne monoprophylaxis (2/15, 13.3%). In the HBV inactive replication group, the outcome was similar to that of the HBV active group. The HBV antibody frequency was HBs- Ab 4/7, HBcAb 6/7, and HBeAb 2/7. Three of 7 recipients showed HBV clearance both in sera and liver biopsy sam- ples , whereas in the control group all 3 recipients developed HBV allograft reinfection and recurrent hepatitis 8, 10, 12 months postoperatively; one of them died of fibrosing cho- lestatic hepatitis, and the remaining 2 recovered after addi- tional lamivudine therapy. The overall allograft reinfection rate was 9.1% (2/22) and the overall 1-, 2-year survival rates were 87%) in the lamivudine prophylaxis group. CONCLUSIONS: Lamivudine prophylaxis can prevent ef- fectively liver allograft from HBV reinfection in patients with HBV-related decompensated liver cirrhosis even in HBV active replication recipient after liver transplantation. Its long-term outcome remains to be studied.展开更多

Chronic hepatitis B virus(HBV) infection(CHB) is the most important etiologic factor of this tumor, accounting for the development of more than50% of the cases in the world. Primary prevention ofHCC is possible by hepatitis B vaccination conferring protection from HBV infection. However, according to the World Health Organization Hepatitis B Fact sheet N° 204(update of July 2014) globally there exists a large pool of > 240 million people chronically infected with HBV who are at risk for development of HCC. These individuals represent a target population for secondary prevention both of cirrhosis and of HCC. Since ongoing HBV replication in CHB is linked with the progression of the underlying liver disease to cirrhosis as well as with the development of HCC, effective antiviral treatment in CHB has also been evaluated in terms of secondary prevention of HCC. Currently, most patients with active CHB are subjected to long term treatment with the first line nucleos(t)ide analogues entecavir and tenofovir. These compounds are of high antiviral potency and have a high barrier to HBV resistance compared to lamivudine, adefovir dipivoxil and even telbivudine. Many studies have shown that patients under antiviral treatment, especially those in virological remission, develop less frequently HCC compared to the untreated ones. However, the risk for development of HCC cannot be eliminated. Therefore, surveillance for the development of HCC of patients with chronic hepatitis B must be lifelong or until a time in the future when new treatments will be able to completely eradicate HBV from the liver particularly in the early stages of CHB infection. In this context, the aim of this review is to outline the magnitude of the risk for development of HCC among patients with CHB, in the various phases of the infection and in relation to virus, host and environmental factors as evaluated in the world literature. Moreover, the benefits of antiviral treatment of CHB with nucleos/tide analogs, which have changed the natural history of the disease and have reduced but not eliminated the risk of HCC are also reviewed.展开更多

It is estimated that about 350 million people throughout the world are chronically infected with HBV. Some of these people will develop hepatic cirrhosis with decompensation and/or hepatocellular carcinoma. For such patients, liver transplantation may be the only hope for cure or real improvement in quality and quantity of life. Formerly, due to rapidity of recurrence of HBV infection after liver transplantation, usually rapidly progressive, liver transplantation was considered to be contraindicated. This changed dramatically following the demonstration that hepatitis B immune globulin (HBIG), could prevent recurrent HBV infection. HBIG has been the standard of care for the past two decades or so. Recently, with the advent of highly active inhibitors of the ribose nucleic acid polymerase of HBV (entecavir, tenofovir), there has been growing evidence that HBIG needs to be given for shorter lengths of time; indeed, it may no longer be necessary at all. In this review, we describe genetic variants of HBV and past, present, and future prophylaxis of HBV infection during and after liver transplantation. We have reviewed the extant medical literature on the subject of infection with the HBV, placing particular emphasis upon the prevention and treatment of recurrent HBV during and after liver transplantation. For the review, we searched PubMed for all papers on the subject of “hepatitis B virus AND liver transplantation”. We describe some of the more clinically relevant and important genetic variations in the HBV. We also describe current practices at our medical centers, provide a summary and analysis of comparative costs for alternative strategies for prevention of recurrent HBV, and pose important still unanswered questions that are in need of answers during the next decade or two. We conclude that it is now rational and cost-effective to decrease and, perhaps, cease altogether, the routine use of HBIG during and following liver transplantation for HBV infection. Here we propose an individualized prophylaxis regimen, based on an integrated approach and risk-assessment.展开更多

文摘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.
文摘BACKGROUND: Patients with decompensated hepatitis B vires (HBV)-related cirrhosis tend to have low or undetectable HBV replication. However, some patients continue to have high levels of HBV replication and effective suppression of HBV replication with antiviral agents may potentially decrease hepatic necroinflammation and improve or stabilize liver function. This review was to under stand the efficacy and safety of lamivudine in the treatment of decompensated HBV cirrhosis. DATA SOURCES: An English-language literature search (MEDLINE January 1988-July 2005) was performed, and a total of 52 articles/abstracts relevant to the issue were selected. After review of the selected papers, the meaningful results and conclusions were extracted using scientific crite ria. The papers reviewed pertained mainly to the efficacy and safety profiles of lamivudine treatment for decompensated HBV cirrhosis. RESULTS: The ultimate treatment of decompensated HBV cirrhosis is liver transplantation, but lamivudine treatment may lead to rapid suppression of viral replication and improvement of biochemical and clinical parameters, reduced morbidity and hospitalization for complications of liver disease, increased pre-transplant survival as well as reduced need for transplantation. However, viral resistance can develop after prolonged treatment with lamivudine, and breakthrough hepatitis may be fatal in few patients. Adefovir is effective for lamivudine-resistant HBV mutants. CONCLUSIONS: Antiviral therapy with lamivudine for decompensated HBV cirrhosis can be effective. However, some patients may experience a hepatitis flare with the emergence of YMDD mutants resulting in progressive worsening of liver disease, and should be referred for 'rescue' therapy with other nucleoside/nucleotide analogues such as adefovir dipivoxil.
文摘AIM: To compare the antiviral efficacy of adefovir (ADV) in lamivudine (LMV)-resistant patients with LMV treatment in nucleoside-naive patients, using serum samples collected sequentially during the course of treatment progressing from LMV to ADV.METHODS: Forty-four patients with chronic hepatitis B (CHB) were included. The patients were initially treated with LMV and then switched to ADV when LMV resistance developed. Antiviral efficacy was assessed by measuring the following: reduction in serum HBV DNA from baseline, HBV DNA negative conversion (defined as HBV DNA being undectable by the hybridization assay), and HBV DNA response (either HBV DNA level ≤ 10^s copies/mL or a ≥ 2 log10 reduction from baseline HBV DNA level).RESULTS: After two and six months of treatment, HBV DNA reduction was greater with LMV compared to ADV treatment (P = 0.021). HBV DNA negative conversion rates were 64% and 27% after one month of LMV and ADV treatment respectively (P = 0.001). Similarly, HBV DNA response rates were 74% and 51% after two months of LMV and ADV treatment respectively (P = 0.026). The time taken to HBV DNA negative conversion and to HBV DNA response were both delayed in ADV treatment compared with LMV.CONCLUSION: The antiviral efficacy of ADV in LMV-resistant patients is slower and less potent than that with LMV in nucleoside-naive patients during the early course of treatment.
文摘Objective:To explore the effect of adefovir dipivoxil in combined with lamivudine on the liver function in patients with hepatitis B cirrhosis and the antiviral efficacy.Methods:A total of 156 patients with hepatitis B cirrhosis who were admitted in our hospital were included in the study and randomized into the treatment group and the control group with 78 cases in each group. The patients in the treatment group were given adefovir dipivoxil in combined with lamivudine, while the patients in the control group were given entecavir. After 12-month treatment, the efficacy was evaluated. The liver function, serum virology indicators, and AFP before and after treatment in the two groups were compared. The adverse reactions during the treatment process were recorded.Results: The serum GTP, ALT, AST, and TBIL levels after treatment in the two groups were significantly reduced when compared with before treatment (P<0.05);moreover, ALT and TBIL levels in the treatment group were significantly lower than those in the control group (P<0.05). HBeAg, HBV-DNA, and AFP levels after treatment in the two groups were significantly reduced when compared with before treatment (P<0.05), HBeAg and AFP levels in the treatment group were significantly lower than those in the control group (P<0.05), and the comparison of HBV-DNA between the two groups was not statistically significant (P>0.05). ALT normalization rate and HBeAg negative conversion rate after treatment in the treatment group were significantly higher than those in the control group (P<0.05). The comparison of HBV-DNA negative conversion rate and HBeAg conversion rate between the two groups was not statistically significant (P>0.05). No obvious drug adverse reactions and liver function damage occurred during the treatment process in the two groups. Conclusions:Adefovir dipivoxil in combined with lamivudine can significantly improve the liver function and serum virology indicators in patients with hepatitis B cirrhosis, with antiviral efficacy significantly superior to that by entecavir.
文摘AIM:To investigate the effect of antiviral therapy with nucleoside analogs in hepatitis B virus(HBV)-related cirrhosis and esophageal varices.METHODS:Eligible patients with HBV-related cirrhosis and esophageal varices who consulted two tertiary hospitals in Beijing,China,the Chinese Second Artillery General Hospital and Chinese PLA General Hospital,were enrolled in the study from January 2005 to December 2009. Of 117 patients,79 received treatment with different nucleoside analogs and 38 served as controls. Bleeding rate,change in variceal grade and non-bleeding duration were analyzed. Multivariate Cox proportional hazard regression was used to identify factors related to esophageal variceal bleeding.antiviral group compared to the control group(29.1%vs 65.8%,P < 0.001). Antiviral therapy was an independent factor related to esophageal bleeding in multivariate analysis(HR = 11.3,P < 0.001). The mean increase in variceal grade per year was lower in the antiviral group(1.0 ± 1.3 vs 1.7 ± 1.2,P = 0.003). Nonbleeding duration in the antiviral group was prolonged in the Kaplan-Meier model. Viral load rebound was observed in 3 cases in the lamivudine group and in 1 case in the adefovir group,all of whom experienced bleeding. Entecavir and adefovir resulted in lower bleeding rates(17.2% and 28.6%,respectively) than the control(P < 0.001 and P = 0.006,respectively),whereas lamivudine(53.3%) did not(P = 0.531).CONCLUSION:Antiviral therapy delays the progression of esophageal varices and reduces bleeding risk in HBV-related cirrhosis,however,high-resistance agents tend to be ineffective for long-term treatment.

文摘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.
文摘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.
文摘A 69-year-old man was admitted to our hospital in October 2003,for further examination of two liver tumors.He was diagnosed with hepatocellular carcinoma(HCC) arising from decompensated hepatitis B virus(HBV)-related cirrhosis.Long-term lamivudine administration improved liver function dramatically despite repeated treatment for HCC.His Child-Pugh score was 9 points at start of lamivudine treatment,improving to 5 points after 1 year.His indocyanine green at 15 min after injection test score was 48%before lamivudine treat-ment,improving to 22%after 2 years and to 5%after 4 years.Radiofrequency ablation controlled the HCC foci and maintained his liver function.In April 2009,abdominal computed tomography revealed a tumor thrombus in the right portal vein.Since his indocyanine green test results had improved to less than 10%,we performed a right hepatectomy,which was successful.To our knowledge,there have been no documented reports of patients undergoing successful right hepatectomy for HCC arising from decompensated cirrhosis.The findings observed in our patient indicate the importance of nucleoside analogs for treating HBV-related HCC.

文摘AIM:To investigate the appropriate time for combination therapy in HBeAg positive chronic hepatitis B(CHB) patients with decompensated cirrhosis.METHODS:Thirty HBeAg positive CHB patients with decompensated cirrhosis were enrolled in the study.All of the patients were given 48 wk combination therapy with lamivudine(LAM) and adefovir dipivoxil(ADV) .Briefly,10 patients were given the de novo combination therapy with LAM and ADV,whereas the other 20 patients received ADV in addition to LAM after hepatitis B virus(HBV) genetic mutation.RESULTS:Serum alanine aminotransferase and total bilirubin were both improved in the two groups at 4,12,24 and 48 wk after treatment.Serum albumin was also improved at 24 and 48 wk after combination therapy in both groups.The serum HBV DNA level wasstill detectable in every patient in the two groups at 4 and 12 wk after combination treatment.However,in the de novo combination group,serum HBV DNA levels in 4(40%) and 9(90%) patients was decreased to below 1×10 3 copies/mL at 24 and 48 wk after the combination treatment,respectively.In parallel,serum HBV DNA levels in 2(20%) and 8(40%) patients in the add-on combination group became undetectable at 24 and 48 wk after combination treatment,respectively.Furthermore,6(60%) patients in the de novo combination group achieved HBeAg seroconversion after 48 wk treatment,whereas only 4(20%) patients in the add-on combination group achieved seroconversion.Child-Pugh score of patients in the de novo combination group was better than that of patients in the add-on combination group after 48 wk treatment.Moreover,patients in the de novo combination group had a significantly decreased serum creatinine level and elevated red blood cell counts.CONCLUSION:De novo combination therapy with LAM and ADV was better than add-on combination therapy in terms of Child-Pugh score,virus inhibition and renal function.
文摘AIM: To determine the efficacy of long-term lamivudine treatment of a large number of Japanese patients with chronic hepatitis B. METHODS: In this retrospective, multi-center trial, 318 Japanese patients with chronic hepatitis B received 100 mg of lamivudine daily for up to 36 (median 21) mo. Virological response was a decline to a serum HBV DNA level less than 3.7 log copies/mL. Virological breakthrough was defined as the reappearance of a serum HBV DNA level to more than 10-fold the minimum during treatment. RESULTS: Lamivudine produced virological response in 86.8% of the 318 patients at 6 mo, in 80.2% of 252 patients at 12 mo, in 69.2% of 133 patients at 24 mo, and in 53.6% of 28 patients at 36 mo. Forward stepwise logistic regression analysis showed an HBV DNA level less than 6.8 log copies/mL (P〈 0.0001), HBeAg negativity (P〈 0.0001), a platelet count of 100×10^9/L or more (P= 0.0162) at baseline, and a decline of the HBV DNA level of more than 3.2 log copies/mL as compared with the baseline level at 3 mo after the start of treatment (P= 0.0003) to be significantly associated with virological response. Among patients with a virological response, virological breakthrough was seen in 5.3% of 19 patients who responded virologically at 1 mo, in 20.7% of 203 patients at 3 mo, in 27.5% of 51 patients at 6 mo, in 33.3% of 12 patients at 9 mo, and in 100% of 3 patients at ≥15 mo. A virological breakthrough was found significantly more often in patients with delayed virological response. CONCLUSION: Lamivudine treatment could suppress serum HBV DNA in most of the tested Japanese patients. Long-term efficacy might be seen in patients without HBeAg at baseline, in the absence of cirrhosis, and in patients with a decline in HBV DNA level soon after the start of treatment.
文摘Objective:To study the effect of Qianggan Pills combined with antiviral treatment on the fibrosis indexes, immune and inflammatory response in patients with compensated hepatitis b cirrhosis.Methods:A total of 88 patients with compensated hepatitis b cirrhosis treated in our hospital between April 2013 and March 2016 were collected and divided into observation group and control group according to single blind randomized control. Observation group of patients accepted Qianggan Pills combined with antiviral treatment and control group of patients received antiviral treatment alone. After 6 months of treatment, chemiluminescence method was used to detect serum fibrosis indexes, flow cytometer was used to detect peripheral blood T lymphocyte subset levels, and enzyme-linked immunosorbent assay (ELISA) was used to detect serum levels of inflammatory factors.Results: Before treatment, differences in fibrosis indexes, immune and inflammatory response indexes were not statistically significant between two groups of patients;after 6 months of treatment, serum LN, HA andⅣ-C levels of observation group were lower than those of control group, peripheral blood CD3+ and CD4+T lymphocyte levels as well as CD4+/CD8+ ratio were higher than those of control group, and CD8+ T lymphocyte level was lower than that of control group;serum PCT and CRP levels were lower than those of control group while IL-10 and IL-13 levels were higher than those of control group.Conclusion:Qianggan Pills combined with antiviral treatment can inhibit the fibrosis process, strengthen the body's immune function and also relieve systemic inflammatory response in patients with compensated hepatitis b cirrhosis.
文摘Patients with chronic hepatitis B are at increased risk of hepatocellular carcinoma(HCC),while the inhibition of viral replication can represent a reasonable target for HCC prevention.Interferon-αtherapy results in decreased HCC risk,which is more evident in patients with high baseline HCC risk.The majority of chronic hepatitis B patients are treated with a nucleos(t)ide analogue(NA)for several reasons including the nonsustained response after interferon-α.The effect of the first licensed and low genetic barrier NA,lamivudine,on HCC incidence,has been repeatedly evaluated.Lamivudine,compared to no treatment,reduces the HCC incidence,which may increase again in cases with lamivudine resistance.Emerging data with the currently first-line NAs,entecavir and tenofovir,suggest that they also reduce the HCC incidence.The treatment benefit in reduction of the HCC incidence is always greater in patients with high baseline HCC risk,particularly cirrhotics,and without virological remission under entecavir/tenofovir.However,the HCC risk is not eliminated even in the vast majority of patients who remain in virological remission under entecavir/tenofovir.Therefore,patients at increased baseline HCC risk should continue to undergo HCC surveillance even if they have achieved complete long-term inhibition of viral replication and improvements in liver histology.

文摘AIM: To observe the effect of response-guided add-on therapy with adefovir(ADV) and lamivudine(LAM) in cirrhotic hepatitis B(CHB) patients.METHODS: A total of 100 patients with CHB and cirrhosis were divided into three arms according to hepatitis B virus(HBV) DNA level after 24 wk LAM monotherapy: Arm A(complete response, HBV DNA ≤ 60 IU/m L, n = 49), Arm B(partial response, HBV DNA: 60-2000 IU/m L, n = 31) and Arm C(inadequate response, HBV DNA > 2000 IU/m L, n = 20). ADV was added to LAM at week 48 in Arms A and B, but at week 24 in Arm C. Virological response, YMDD mutations, biochemical response, and liver function were evaluated.RESULTS: Comparison of the three arms demonstrated that early complete virologic response at week 24was associated with maintained viral suppression(undetectable rate of HBV DNA at week 144 was 95.96%, 66.67% and 35.29%, respectively, P = 0.000) and reduced YMDD mutations(mutation rate at week 144 was 0%, 3.23% and 15%, respectively, P = 0.015) after 144 wk treatment. For patients who failed to achieve complete virological response at week 24, switching to combination therapy further decreased HBV DNA level by 1 log10 IU/m L. All three arms obtained biochemical benefits including decline of alanine aminotransferase and elevation of albumin. In patients who developed HBV DNA breakthrough for YMDD mutations, ADV add-on therapy did not induce further multiple drug resistance to LAM or ADV.CONCLUSION: Optimized response-guided add-on therapy of ADV and LAM maintains long-term suppression of HBV DNA and improves liver function in CHB patients with compensated liver cirrhosis.
文摘This review analyzes progress and limitations of diagnosis, screening, and therapy of patients with chronic hepatitis B infection. A literature review was carried out by framing the study questions. Vaccination in early childhood has been introduced in most countries and reduces the infection rate. Treatment of chronic hepatitis B can control viral replication in most patients today. It reduces risks for progression and may reverse liver fibrosis. The treatment effect on development of hepatocellular carcinoma is less pronounced when cirrhosis is already present. Despite the success of vaccination and therapy chronic hepatitis B remains a problem since many infected patients do not know of their disease. Although all guidelines recommend screening in high risk groups such as migrants, these suggestions have not been implemented. In addition, the performance of hepatocellular cancer surveillance under real-life conditions is poor. The majority of people with chronic hepatitis B live in resource-constrained settings where effective drugs are not available. Despite the success of vaccination and therapy chronic hepatitis B infection remains a major problem since many patients do not know of their disease. The problems in diagnosis andscreening may be overcome by raising awareness, promoting partnerships, and mobilizing resources.
文摘Chronic hepatitis B virus infection affects about 400 million people around the globe and causes approximately a million deaths a year. Since the discovery of interferon-α as a therapeutic option the treatment of hepatitis B has evolved fast and management has become increasingly complicated. The amount of viral replication reflected in the viral load (HBV-DNA) plays an important role in the development of cirrhosis and hepatocellular carcinoma. The current treatment modalities for chronic hepatitis B are immunomodulatory (interferons) and antiviral suppressants (nucleoside and nucleotide analogues) all with their own advantages and limitations. An overview of the treatment efficacy for both immunomodulatory as antiviral compounds is provided in order to provide the clinician insight into the factors influencing treatment outcome. With nucleoside or nucleotide analogues suppression of viral replication by 5-7 log10 is feasible, but not all patients respond to therapy. Known factors influencing treatment outcome are viral load, ALT levels and compliance. Many other factors which might influence treatment are scarcely investigated. Identifying the factors associated with response might result in stopping rules, so treatment could be adapted in an early stage to provide adequate treatment and avoid the development of resistance. The efficacy of compounds for the treatment of mutant virus and the cross-resistance is largely unknown. However, genotypic and phenotypic testing as well as small clinical trials provided some data on efficacy in this population. Discontinuation of nucleoside or nucleotide analogues frequently results in viral relapse; however, some patients have a sustained response. Data on the risk factors for relapse are necessary in order to determine when treatment can be discontinued safely. In conclusion: chronic hepatitis B has become a treatable disease; however, much research is needed to tailor therapy to an individual patient, to predict the sustainability of response and determine the best treatment for those failing treatment.

文摘BACKGROUND: Liver allograft hepatitis B virus (HBV) reinfection and hepatitis B (HB) recurrence jeopardize the long-term survival of recipient and liver allograft. Lamivu- dine has been referred as a novel antiviral agent against HBV in HBV cirrhotic patients even in liver transplantation setting. We assessed the prophylatic effect of lamivudine on liver allograft HBV reinfection and clarified the dynamic changes of HBV markers in HBV related decompensated liver cirrhosis after liver transplantation. METHODS: Twenty-five recipients were divided into three groups: HBV active replication group (15 recipients), HBV inactive replication group (7), and control group (3). 100 mg/d lamivudine was administered preoperatively except in the control group. The HBV markers of serial sera and liver biopsy samples of the 25 recipients were evaluated re- gularly with enzyme-linked radioimmunoassay, HBV DNA fluorecent quantitative assay, immunohistochemical stain- ing , labelled streptavidin biotin ( LSAB) and digoxin la- belled HBV DNA hybridization in situ. The dynamic alter- nation of HBV markers under lamivudine prophylaxis was observed. RESULTS: In the HBV active replication group who had received lamivudine 2 weeks before liver transplantation, serum HBV DNA positive converted to negative by 80%. HBsAg of all recipients disappeared after liver transplanta- tion , but corresponding antibodies of HBV appeared within one week after the operation. HBsAb 9/15, HBcAb 13/15 and HBeAb 11/15 appeared and subsided gradually within 24 weeks. HBV DNA in sera was kept negative; HBsAg, HBcAg and HBV DNA hybridization in situ of liver biopsy samples remained negative after use of lamivudine. Ten of the 15 recipients showed clearance of HBV, and per se HBV markers were undetectable both in serum and liver bi- opsy samples between 12 to 44 weeks (24 weeks on ave- rage). The 1-, 2-year survival rates were 83% in this group. Two of the 15 recipients developed HBV allograft reinfection or recurrence of hepatitis 2 years after lamivudi- ne monoprophylaxis (2/15, 13.3%). In the HBV inactive replication group, the outcome was similar to that of the HBV active group. The HBV antibody frequency was HBs- Ab 4/7, HBcAb 6/7, and HBeAb 2/7. Three of 7 recipients showed HBV clearance both in sera and liver biopsy sam- ples , whereas in the control group all 3 recipients developed HBV allograft reinfection and recurrent hepatitis 8, 10, 12 months postoperatively; one of them died of fibrosing cho- lestatic hepatitis, and the remaining 2 recovered after addi- tional lamivudine therapy. The overall allograft reinfection rate was 9.1% (2/22) and the overall 1-, 2-year survival rates were 87%) in the lamivudine prophylaxis group. CONCLUSIONS: Lamivudine prophylaxis can prevent ef- fectively liver allograft from HBV reinfection in patients with HBV-related decompensated liver cirrhosis even in HBV active replication recipient after liver transplantation. Its long-term outcome remains to be studied.
文摘Hepatocellular carcinoma(HCC) is a major health problem worldwide, representing one of the leading causes of death. Chronic hepatitis B virus(HBV) infection(CHB) is the most important etiologic factor of this tumor, accounting for the development of more than50% of the cases in the world. Primary prevention ofHCC is possible by hepatitis B vaccination conferring protection from HBV infection. However, according to the World Health Organization Hepatitis B Fact sheet N° 204(update of July 2014) globally there exists a large pool of > 240 million people chronically infected with HBV who are at risk for development of HCC. These individuals represent a target population for secondary prevention both of cirrhosis and of HCC. Since ongoing HBV replication in CHB is linked with the progression of the underlying liver disease to cirrhosis as well as with the development of HCC, effective antiviral treatment in CHB has also been evaluated in terms of secondary prevention of HCC. Currently, most patients with active CHB are subjected to long term treatment with the first line nucleos(t)ide analogues entecavir and tenofovir. These compounds are of high antiviral potency and have a high barrier to HBV resistance compared to lamivudine, adefovir dipivoxil and even telbivudine. Many studies have shown that patients under antiviral treatment, especially those in virological remission, develop less frequently HCC compared to the untreated ones. However, the risk for development of HCC cannot be eliminated. Therefore, surveillance for the development of HCC of patients with chronic hepatitis B must be lifelong or until a time in the future when new treatments will be able to completely eradicate HBV from the liver particularly in the early stages of CHB infection. In this context, the aim of this review is to outline the magnitude of the risk for development of HCC among patients with CHB, in the various phases of the infection and in relation to virus, host and environmental factors as evaluated in the world literature. Moreover, the benefits of antiviral treatment of CHB with nucleos/tide analogs, which have changed the natural history of the disease and have reduced but not eliminated the risk of HCC are also reviewed.

文摘Hepatitis B virus (HBV) continues to be a major cause of morbidity and mortality worldwide. It is estimated that about 350 million people throughout the world are chronically infected with HBV. Some of these people will develop hepatic cirrhosis with decompensation and/or hepatocellular carcinoma. For such patients, liver transplantation may be the only hope for cure or real improvement in quality and quantity of life. Formerly, due to rapidity of recurrence of HBV infection after liver transplantation, usually rapidly progressive, liver transplantation was considered to be contraindicated. This changed dramatically following the demonstration that hepatitis B immune globulin (HBIG), could prevent recurrent HBV infection. HBIG has been the standard of care for the past two decades or so. Recently, with the advent of highly active inhibitors of the ribose nucleic acid polymerase of HBV (entecavir, tenofovir), there has been growing evidence that HBIG needs to be given for shorter lengths of time; indeed, it may no longer be necessary at all. In this review, we describe genetic variants of HBV and past, present, and future prophylaxis of HBV infection during and after liver transplantation. We have reviewed the extant medical literature on the subject of infection with the HBV, placing particular emphasis upon the prevention and treatment of recurrent HBV during and after liver transplantation. For the review, we searched PubMed for all papers on the subject of “hepatitis B virus AND liver transplantation”. We describe some of the more clinically relevant and important genetic variations in the HBV. We also describe current practices at our medical centers, provide a summary and analysis of comparative costs for alternative strategies for prevention of recurrent HBV, and pose important still unanswered questions that are in need of answers during the next decade or two. We conclude that it is now rational and cost-effective to decrease and, perhaps, cease altogether, the routine use of HBIG during and following liver transplantation for HBV infection. Here we propose an individualized prophylaxis regimen, based on an integrated approach and risk-assessment.
