Kinetics of hepatitis B surface antigen and estimated glomerular filtration rate in telbivudine-treated hepatitis B patients with different rescue strategies. PLoS One 2020; 15:e0237586. [PMID: 32785260 PMCID: PMC7423127 DOI: 10.1371/journal.pone.0237586] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2020] [Accepted: 07/29/2020] [Indexed: 01/09/2023] Open
Abstract
This study investigated the kinetics of estimated glomerular filtration rate (eGFR) and quantitative hepatitis B surface antigen (qHBsAg) in telbivudine (LdT)-treated chronic hepatitis B (CHB) patients whose treatment was subsequently adjusted with the adding on adefovir or by switching to tenofovir disoproxil fumarate (TDF) as rescue. Of 295 CHB patients initially treated with LdT, 102 of them who subsequently receiving either adding-on adefovir (group A, n = 58) or switching to TDF (group B, n = 44) for more than 24 months were enrolled. Serial eGFR and qHBsAg levels (3 to 6 monthly) in both LdT monotherapy and rescue therapy periods were analyzed retrospectively. Subsequent decline of qHBsAg especially in rescue therapy period were noted (p<0.001 and p = 0.068 in group A and B). However, patients in group B achieved a significant increase of eGFR (p = 0.010) in LdT monotherapy period but had a significant decline of eGFR (p<0.001) in rescue therapy period. In contrast, patients in group A maintained eGFR levels in both periods. Meanwhile, switch to TDF (hazard ratio: 3.036; 95% confidence interval: 1.040-8.861; p = 0.042) was the sole factor related to the decrease of eGFR>20% from baseline. Both rescue therapies achieved subsequent declines of qHBsAg over time but caused different changes in eGFR. LdT-based rescue therapy maintained eGFR but TDF switching therapy descended eGFR. Therefore, it is essential to monitor patient's renal function intensively when switching from LdT to TDF as a rescue strategy.

Dig Dis Sci 2019; 64:3630-3641. [PMID: 31280390 DOI: 10.1007/s10620-019-05717-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/08/2019] [Accepted: 07/02/2019] [Indexed: 01/10/2023]
Abstract
AIM Renal toxicity of adefovir disoproxil (ADV) and tenofovir disoproxil fumarate (TDF) is a significant concern in chronic hepatitis B (CHB) patients. Early observational clinical data suggested that telbivudine (LdT) might have renoprotective effects. METHODS In this prospective study, consecutive CHB patients on combined lamivudine (LAM) + ADV/TDF were switched to LdT + ADV/TDF at recruitment and were followed up for 24 months. Estimated glomerular filtration rate (eGFR) was calculated with the modification of diet in renal disease equation. The effects of LdT on cell viability and expression of kidney injury or apoptotic biomarkers were investigated in cultured renal tubular epithelial cell line HK-2. RESULTS Thirty-one patients (median age 55 years, 90.3% male) were recruited (54.8% TDF: 45.2% ADV). Serum HBV DNA was undetectable at all time points. Median eGFR was 70.2 (IQR 62.6-77.9) and 81.5 (IQR 63.6-99.1) mL/min/1.73 m2 at baseline and 24 months, respectively (p < 0.001). Downstaging of chronic kidney disease was observed in eight (25.8%) patients and was more common in ADV-treated compared to TDF-treated patients (7/8 vs. 1/17, p = 0.011; OR 16, 95% CI 1.643-155.766, p = 0.017). In vitro data showed that adding LdT to ADV or TDF was associated with improved cell viability and lower expression of injury and apoptotic biomarkers compared with ADV or TDF alone. Treatment was prematurely discontinued in four(12.9%) patients due to myalgia. CONCLUSIONS Clinical and in vitro data suggest that LdT has renoprotective effects in patients on long-term ADV/TDF treatment. LdT may be considered as an adjuvant therapy in this special group of patients with renal impairment (NCT03778567).

Abstract
Few studies have addressed the impact of adefovir dipivoxil (ADV)-based combination therapy on the renal function of patients with chronic hepatitis B (CHB). This study evaluated the effects of ADV combined with other antiviral nucleotide analogs (NAs) on renal function of patients with CHB, and analyzed the risk factors for more than 20% reduction of baseline estimated glomerular filtration rate (eGFR).The data of 164 patients with CHB were retrospectively analyzed in this study. Of the 164 patients, 42 received entecavir (ETV) combined with ADV (ETV + ADV group), 68 lamivudine (LAM) combined with ADV (LAM + ADV group), and 54 telbivudine (LDT) combined with ADV (LDT + ADV group). Serum creatinine (SCr) level, eGFR, and proportion of patients with eGFR ≥ 90 mL/min/1.73 m were observed. Also, the independent risk factors for more than 20% reduction of baseline eGFR were analyzed.After 104-week combination therapy, compared with the baseline level, SCr levels were significantly increased in the ETV + ADV group (67 μmol/L vs 73 μmol/L, P = .012) and LAM + ADV group (68 μmol/L vs 79 μmol/L, P = .008), but it was significantly decreased in the LDT + ADV group (69 μmol/L vs 64 μmol/L, P = .023). Compared with the baseline level, eGFR was significantly decreased in the ETV + ADV group (107.8 mL/min/1.73 m vs 96.1 mL/min 1.73/m, P = .004), and LAM + ADV group (105.4 mL/min/1.73 m vs 87.3 mL/min/1.73 m, P = .000), but it was significantly increased in the LDT + ADV group (104.1 mL/min 1.73/m vs 116.2 mL/min/1.73 m,P = .005). The proportion of patients with normal renal function (≥90 mL/min/1.73 m) was significantly higher in the LDT + ADV group than in the ETV + ADV group (P = .002) and LAM + ADV group (P = .001). Multivariate analysis showed that age (P = .035), male (P = .005), baseline eGFR (P < .001), LAM combined with ADV (P < .008), and ETV combined with ADV (P = .03) were independent risk factors for 20% reduction of baseline eGFR.As compared with ETV and ADV combination therapy as well as LAM and ADV combination therapy, LDT and ADV combination therapy can improve eGFR level, so LDT and ADV combination therapy is suitable for the patients with potential renal impairment.

Abstract
AIM To explore the serum conversion rate of hepatitis B e antigen (HBeAg) and renal function in patients with chronic hepatitis B (CHB) treated with aldefovir dipivoxil (ADV) plus telbivudine (L-DT).
METHODS This retrospective cohort study included 42 patients with HBeAg-negative CHB who were on ADV (10 mg) monotherapy. Twenty patients were treated with L-DT add-on therapy (combination therapy group), and 22 patients were switched to ETV monotherapy (monotherapy group). At 24 and 48 wk, the conversion rate of HBeAg and renal function evaluated by estimated glomerular filtration rate (eGFR) were analyzed and compared between the two groups.
RESULTS The eGFR at 24 and 48 wk did not differ significantly between the two groups (P = 0.773, 0.108). The eGFR in the combination therapy group was significantly higher at 48 wk than at baseline (t = -6.184, P < 0.05), but no significant difference was observed in the monotherapy group (t = -0.893, P > 0.05). The serum conversion rates of HBeAg at 24 wk and 48 wk were significantly higher in the combination therapy group than in the monotherapy group (P = 0.043, 0.034).
CONCLUSION L-DT based treatment is effective in elevating the serum conversion rate of HBeAg, and long-term therapy is associated with sustained improvement of renal function, particularly among HBeAg-negative CHB patients treated with ADV.

Abstract
BACKGROUND Safety profile of nucleos(t)ide analogues is an important issue in view of its widespread use for decades in patients with chronic hepatitis B (CHB). AIM To review and evaluate the latest evidence on the safety profiles of the six approved nucleoside analogues. METHODS Relevant articles related to nucleoside analogue safety were selected for review following extensive language- and date-unrestricted, electronic searches of the literature. RESULTS Nephrotoxicity has been well reported in patients receiving older generations of nucleotide analogues, namely adefovir dipivoxil and tenofovir disoproxil fumarate (TDF). Yet risks of renal failure and renal replacement therapy were similar in patients treated with nucleoside analogues versus nucleotide analogues in real-life setting. Bone toxicity is closely related to nucleoside analogue effect on renal proximal tubular and phosphaturia. Real-life data demonstrated increased risk of hip fracture in patients receiving adefovir but not TDF. The newly approved tenofovir alafenamide (TAF) has improved renal and bone safety profiles compared to TDF. Long-term use of nucleoside analogues eg entecavir does not increase the risk of other cancers. Muscular toxicity may be seen in telbivudine-treated patients so regular monitoring is advised. Peripheral neuropathy and lactic acidosis are rare adverse events. Latest international guidelines support the use of TDF, telbivudine and lamivudine during pregnancy; breastfeeding is not contraindicated during TDF therapy. CONCLUSIONS Long-term safety profile of nucleoside analogues is now better defined with more data from large real-life cohorts and clinical trials with long-term follow-up. The new nucleotide analogue, TAF is now available with favourable renal and bone safety profiles.

Telbivudine attenuates UUO-induced renal fibrosis via TGF-β/Smad and NF-κB signaling. Int Immunopharmacol 2017; 55:1-8. [PMID: 29207359 DOI: 10.1016/j.intimp.2017.11.043] [Citation(s) in RCA: 33] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2017] [Revised: 11/21/2017] [Accepted: 11/28/2017] [Indexed: 01/13/2023]
Abstract
Renal fibrosis yields decreased renal function and is a potent contributor to chronic kidney disease (CKD). Telbivudine (LdT) is an anti-hepatitis B virus (HBV) drug that has been found to steadily improve renal function, but the mechanism of drug action is unclear. One explanation is that LdT impacts inflammatory or fibrotic pathways. In this study, we investigated renal protection by LdT in a rat model of unilateral ureteral obstruction (UUO). UUO rats received oral gavage of LdT (1, 1.5, or 2g/kg/day) for 5weeks. Kidney tissues were examined histopathologically with hematoxylin and eosin and Masson's trichrome stain. To assess proliferation of myofibroblasts and matrix accumulation, α-smooth muscle actin (α-sma) and collagen type I and III were detected. Interleukin-1 (IL-1) and tumor necrosis factor (TNF)-α were evaluated as a measure of proinflammatory cytokines. Transforming growth factor (TGF)-β and nuclear factor-κB (NF-κB) were considered the canonical signaling components in our investigation of the underlying mechanism of LdT action. Histopathology results indicated that LdT ameliorates renal injury and matrix accumulation. Expression of α-sma and collagen I/III as well as key fibrotic signaling factors in the TGF-β/Smad pathway were downregulated. In addition, LdT suppressed the release of IL-1 and TNF-α and decreased the expression of NF-κB by inhibiting toll-like receptor 4. Taken together, these findings indicate that LdT can attenuate renal fibrosis and inflammation via TGF-β/Smad and NF-κB pathways in UUO.

Abstract
Hepatitis B virus infection is currently the most important cause of chronic viral hepatitis worldwide and is one of the most frequent causes of end-stage liver disease. With the international implementation of the hepatitis B vaccine and combined prophylaxis for infants born to HBsAg(+) mothers, the prevalence of hepatitis B has decreased remarkably. However, intra-uterine transmission has become a critical bottleneck for eliminating hepatitis B infection. The efficacy of nucleos(t)ide analogs on inhibiting hepatitis B replication has been widely confirmed, and the quality of life and the survival of individuals with chronic hepatitis B (CHB) have improved to a great degree. However, with the availability of long-term antiviral treatment and the ever increasing ageing population, renal disorders should be considered when choosing antiviral medicines. The antiviral efficacy and safety of telbivudine (LdT) have been shown in patients with CHB infection, and LdT is approved as a class B drug for pregnancy. Furthermore, the renal protective function of LdT has been demonstrated recently. In this review, we will focus on the efficacy and safety of LdT in gravidas with CHB infection, as well as the renal protective function of LdT in CHB patients. LdT might provide physicians with a solid option for effectively treating patients with CHB, especially gravidas or those either with or at risk of renal impairment.

Abstract
Although high potent nucleos(t)ide analogues are strongly recommended as first-line therapy for chronic hepatitis B (CHB) in China, some patients are still being treated with adefovir disoproxil (ADV), especially those low-income patients whose health insurance could not reimburse the drug cost. Therefore, the management of patients who have failed ADV therapy or who sustained renal damage during ADV therapy remains an important clinical problem in China. This retrospective study aimed to compare the efficacy and safety of lamivudine (LAM), telbivudine (LdT) or entecavir (ETV) add-on strategies to optimize the treatment of patients with prior suboptimal response to ADV monotherapy. A total of 277 eligible patients were included in this study, and the baseline characteristics were similar among the LAM + ADV (n = 116), LdT + ADV (n = 72) and ETV + ADV (n = 89) groups. At week 96, both the proportion of undetectable HBV DNA (81.03% for LAM + ADV, 84.72% for LdT + ADV and 88.76% for ETV + ADV; P = .317) and ALT elevation (5.17% for LAM + ADV, 4.17% for LdT + ADV and 4.49% for ETV + ADV; P = 1.000) were similar among the three groups; also, a significant decline in liver stiffness was observed in each group from baseline to week 96. At week 96, the rate of HBeAg seroconversion was significantly higher in LdT + ADV than in LAM + ADV (26.39% vs 13.79%, P = .031) and ETV + ADV (26.39% vs 10.11%, P = .007). During the 96 weeks, no obvious renal injury was reported in any of the three groups, but an improvement in eGFR was found in LdT + ADV compared with LAM + ADV and ETV + ADV. In summary, all three combination strategies provide good control of virus replication, but the LdT + ADV combination therapy may yield better HBeAg seroconversion and eGFR improvement.

Abstract
Chronic renal failure is a frequent complication in liver transplantation. Telbivudine, anti-hepatitis B virus (HBV) nucleoside, can improve renal function. It is interesting if using telbivudine for prophylaxis of HBV recurrence has additional value on renal function improvement. 120 liver transplant recipients with lamivudine prophylaxis for HBV recurrence were 1 : 1 randomized into lamivudine-continuous (n = 60) and telbivudine-replacement (n = 60) groups. Fifty-eight patients in lamivudine-continuous group and 54 in telbivudine-replacement group completed the study. In telbivudine-replacement group, the estimated glomerular filtration rate (eGRF) was improved from 63.0 ± 16.3 ml/min to 72.8 ± 21.1 ml/min at 12 months after telbivudine administration (p = 0.003). Stratifying the patients according to renal function staging, the eGRF was improved from 74.7 ± 6.9 ml/min to 84.2 ± 16.6 ml/min (p = 0.002) in 32 stage II patients and from 48.2 ± 7.3 ml/min to 59.7 ± 11.8 ml/min in 20 stage III patients after 12 months of telbivudine administration (p < 0.001). Eleven (18.3%) patients with telbivudine developed polyneuritis during the trial and post hoc following-up. In conclusion, renal function was improved by telbivudine in liver transplant recipients with long-term chronic kidney disease. However, the high incidence of polyneuritis induced by telbivudine has to be closely monitored. This trial is registered with ClinicalTrials NCT02447705.

Abstract
BACKGROUND AND AIM The improvement of estimated glomerular filtration rates (eGFRs) in chronic hepatitis B (CHB) patients receiving telbivudine therapy is well known. The aim of this study was to clarify the kinetics of eGFRs and to identify the significant factors related to the improvement of eGFRs in telbivudine-treated CHB patients in a real-world setting. METHODS Serial eGFRs were calculated every 3 months using the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation. The patients were classified as CKD-1, -2, or -3 according to a baseline eGFR of ≥90, 60-89, or <60 mL/min/1.73 m2, respectively. A significant improvement of eGFR was defined as a more than 10% increase from the baseline. RESULTS A total of 129 patients were enrolled, of whom 36% had significantly improved eGFRs. According to a multivariate analysis, diabetes mellitus (DM) (p = 0.028) and CKD-3 (p = 0.043) were both significantly related to such improvement. The rates of significant improvement of eGFR were about 73% and 77% in patients with DM and CKD-3, respectively. CONCLUSIONS Telbivudine is an alternative drug of choice for the treatment of hepatitis B patients for whom renal safety is a concern, especially patients with DM and CKD-3.

Telbivudine attenuates gentamicin-induced kidney injury in rats. Int J Antimicrob Agents 2017; 49:595-602. [PMID: 28373116 DOI: 10.1016/j.ijantimicag.2017.01.015] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2016] [Revised: 12/26/2016] [Accepted: 01/06/2017] [Indexed: 01/10/2023]
Abstract
Nephrotoxicity has been associated with nucleos(t)ide analogues other than telbivudine (LdT). This study investigated the potential effects of LdT and lamivudine (LAM) on renal function in an experimental rat model of gentamicin-induced acute nephrotoxicity. A total of 28 healthy Wistar albino rats were randomly divided into four experimental groups: negative control; positive control (PC); LdT; and LAM. Nephrotoxicity was induced by gentamicin in the LdT, LAM and PC groups. LdT and LAM were administered to two groups for 6 weeks starting on the ninth day. Blood samples were collected weekly and cystatin C levels were measured by ELISA. Animals were sacrificed on the 50th day and the kidneys were removed for histological examination. Serum cystatin C levels differed significantly between the LdT and LAM groups (P <0.007) and between the LdT and PC groups (P <0.001). Renal function was significantly improved in the LdT group at the start of antiviral treatment on Day 8 and at the end of treatment on Day 50 (P = 0.001 and 0.007). Glomerular injury, acute tubular necrosis and total injury score were significantly reduced in the LdT group relative to the PC and LAM groups upon histopathological examination. LdT was associated with significant improvements in renal function as measured by biochemical and histopathological methods. The acute kidney injury model data should be supported by clinical studies to suggest that LdT treatment may have advantages for patients with underlying chronic kidney disease receiving chronic hepatitis B treatment.

Abstract
Background Controversy remains as to whether antiviral agents contribute to renal dysfunction in patients with chronic hepatitis B virus (HBV) infection. Thus, the aim of study was to analyze the changes in renal function of chronic hepatitis B (CHB) patients in response to anti-HBV therapy and the association with treatments. Method We performed a retrospective observational cohort study to investigate factors associated with renal function in 249 Chinese CHB patients who were treated with pegylated interferon α-2a (PEG-IFN-α-2a) or nucleos(t)ide analogues for 48 weeks. Changes of estimated glomerular filtration rate (eGFR), which was computed with both the Chronic Kidney Disease Epidemiology Collaboration and the Modification of Diet in Renal Disease formulas, were tested by repeated measures One-way analysis of variance within groups. A linear mixed effects model for repeated measures was also used to evaluate the association between baseline information and eGFR changes over time in all enrolled patients. The model considered the baseline age, sex, HBV DNA, aminotransferase, blood urea nitrogen, treatment group, time, and group-by-time interaction as fixed effects and incorporated random effects for individual subjects. Results The eGFR increased in patients given PEG-IFN-α-2a, decreased in patients given adefovir, but remained stable in patients given entecavir. Age and blood urea nitrogen were significant negative predictive factors for eGFR changes. Conclusion In real-life study, PEG-IFN-α-2a therapy in CHB patients increased eGFR, thus may associate with renoprotective effects when compared with adefovir or entecavir therapies.

Abstract
Telbivudine (LdT) is an antiviral agent currently used in the treatment of chronic hepatitis B virus, which was first approved by the US FDA in 2006. The safety of LdT is of great importance for patients that receive long-term treatment for this condition. It has been confirmed that patients treated with LdT have significantly elevated creatine kinase levels. However, the mechanism responsible for this adverse reaction is unclear. This review summarizes the current literature of the adverse reactions of LdT and the possible mechanisms that are involved in chronic hepatitis B infection. Thus, we aim to provide guidance on best practices in using LdT and to provide evidence of the possible mechanisms of LdT-associated adverse reactions.

Abstract
AIM To make efficacy and safety comparison of telbivudine-raodmap and tenofovir-roadmap in hepatitis B e antigen (HBeAg)-negative chronic hepatitis B (CHB) patients.
METHODS This was the first prospective, randomised, two-arm, open-label, non-inferiority study in HBeAg-negative CHB patients that compared telbivudine and tenofovir administered as per roadmap concept. Patients were treated up to 24 wk and, depending on virologic response, continued the same therapy or received add-on therapy up to 104 wk. Eligible patients received an additional 52 wk of treatment in the extension period (i.e., up to 156 wk). Patients who developed virologic breakthrough (VB) while on monotherapy also received add-on therapy. The primary efficacy endpoint was the rate of patients achieving hepatitis B virus (HBV) DNA < 300 copies/mL at week 52. Secondary efficacy endpoints included the rates of HBV DNA < 300 and < 169 copies/mL, HBV DNA change from baseline, alanine aminotransferase normalisation, hepatitis B surface antigen (HBsAg) loss, HBsAg seroconversion, VB, and emergence of resistance at various timepoints throughout the study. Safety and estimated glomerular filtration rate (eGFR) were also analysed.
RESULTS A total of 241 patients were randomised. Non-inferiority of telbivudine arm to tenofovir arm was demonstrated at week 52 (± 7 d window), with over 91% of patients in each treatment arm achieving HBV DNA level < 300 copies/mL. Both arms were similar in terms of key secondary efficacy variables at weeks 104 and 156. The percentage of patients achieving HBV DNA < 300 copies/mL remained high and was similar in the telbivudine and tenofovir arms at both weeks 104 and 156. Over 82% of patients in both arms achieved alanine aminotransferase normalisation at week 52, and this percentage remained high at weeks 104 and 156. Telbivudine treatment progressively reduced serum HBsAg levels from baseline while no change was reported in quantitative HBsAg during therapy with tenofovir. Both treaments showed acceptable safety profiles. The telbivudine arm showed eGFR improvement unlike the tenofovir arm.
CONCLUSION Efficacy was shown for both telbivudine-roadmap and tenofovir-roadmap regimens in HBeAg-negative CHB patients over 156 wk. Telbivudine arm was associated with renal improvement.

Abstract
AIM: To investigate the rate of and risk factors for renal dysfunction in initially treated patients with chronic hepatitis B.
METHODS: Patients with chronic hepatitis B treated at our hospital from November 2013 to October 2015 were divided into a chronic hepatitis B group, a compensated liver cirrhosis group, and a decompensated liver cirrhosis group. The simplified Modification of Diet in Renal Disease Study Equation was used to estimate the glomerular filtration rate (e-GFR) to calculate the rate of renal dysfunction [e-GFR < 90 mL/(min•1.73 m2)]. The risk factors for renal dysfunction were analyzed by univariate and multivariate binary logistic regression analyses.
RESULTS: This study collected a total of 358 cases, of which 15.9% had renal dysfunction. The rate of renal dysfunction was 9.5% for the chronic hepatitis B group, 7.9% for the compensated liver cirrhosis group, and 25.2% for the decompensated group (χ2 = 16.726, P = 0.000). Multivariate binary logistic regression analysis showed that age, sex, disease progression, and kidney stones were independent risk factors for renal dysfunction.
CONCLUSION: Disease progression is an independent risk factor for abnormal renal function in initially treated patients with chronic hepatitis B. Clinicians should make the best decision based on the specific condition of the patient.

Abstract
OBJECTIVE Limited data is available on the clinical outcomes of telbivudine (LdT) and entecavir (ETV) in pre-emptive antiviral chemoprophylaxis. This study aimed to evaluate the clinical efficacy and renal safety of LdT and ETV in patients with chronic hepatitis B (CHB) who received cytotoxic chemotherapy. METHODS Altogether 290 treatment-naïve CHB patients undergoing intense chemotherapy were enrolled to receive daily 600 mg of LdT or 0.5 mg of ETV as pre-emptive antiviral chemoprophylaxis. RESULTS The ETV group had significantly higher proportion of patients with undetectable hepatitis B viral (HBV) DNA load compared with LdT at week 24 (73.0% vs 50.3%, P = 0.000). The cumulative rates of virological breakthrough in the LdT and ETV groups were 9.15% and 3.65% at the second year of therapy, respectively (P = 0.059), which was associated with detectable HBV DNA at week 24 (P = 0.000). The MELD score of the LdT group was significantly lower than that of the ETV group after the first year (4.53 vs 7.53, P = 0.002) and the second year (1.96 vs 7.09, P = 0.000) of antiviral therapy. Moreover, the estimated glomerular filtration rate (eGFR) was significantly improved in the LdT group than in the ETV group after two years of antiviral therapy. CONCLUSION LdT has a lower clinical efficacy in viral suppression than ETV, but LdT is associated with greater extent of improvement in liver and renal functions of patients in pre-emptive prophylaxis for cytotoxic chemotherapy.

Abstract
Background To assess the potential effects of telbivudine (LdT) and entecavir (ETV) on renal function in patients with chronic hepatitis B (CHB), we performed a meta-analysis of the relevant data available on these agents to evaluate their effects on the estimated glomerular filtration rate (eGFR) during treatment. Methods The PubMed, EMBASE, Scopus, CNKI (China National Knowledge Infrastructure), Cochrane Library, and WanFang databases were searched for relevant articles appearing in the literature up to July 1, 2015. A total of 6 studies (1960 CHB patients) with 1-year eGFR outcomes were retrieved and analyzed. Results Generally, the results of the 6 studies analyzed showed that eGFR was improved after LdT treatment, but was decreased after ETV treatment. Using a fixed-effects approach, the change in eGFR was found to be significantly different between LdT and ETV treatment (Z = 3.64; P = 0.0003). Whereas the eGFR was slightly decreased with ETV compared with baseline (−1.45 mL/min/1.73 m2), the eGFR was improved with LdT (2.99 mL/min/1.73 m2) after 1 year of treatment. An overall test of effect in the meta-analysis showed that the eGFR in LdT-treated patients was significantly improved after 1-year of treatment (Z = 3.71; P = 0.0002). Conclusion This meta-analysis has confirmed that LdT has a renal protective effect whereas ETV does not. However, whether the benefit on renal function outweighs the occurrence of resistance in specific clinical situations is not yet clear.

Abstract
It has been reported that treatment with telbivudine might be associated with a significant improvement of renal function in patients with chronic hepatitis B. To confirm this finding, a systematic literature review was conducted. Four online databases (PubMed, CNKI/FMJS, Ovid and SpringerLink) were searched. Serum creatinine, glomerular filtration rate and estimated glomerular filtration rate changes from baseline to the end of the treatment were analyzed. A total of seven full-text articles and 13 abstracts with sample sizes ranging from 15 to 689 patients fulfilled the selection criteria for review. The results showed that long-term treatment with telbivudine, either as monotherapy or combined with other nucleos(t)ide analogs, can significantly improve renal function in chronic hepatitis B patients, particularly those at high risk of renal impairment.

Abstract
INTRODUCTION Oral nucleoside/ nucleotide analogues (NAs) are currently the mainstay of treatment for patients with chronic hepatitis B virus (HBV) infection. They are generally safe to use. However, since their approval in the last decade and a half, the literature has reported adverse effects associated with the use of NA in HBV patients. A comprehensive review on the drug safety is lacking. AREAS COVERED Significant adverse effects associated with NA use in HBV patients including muscle toxicity, peripheral neuropathy, nephrotoxicity and lactic acidosis are discussed. The reported prevalence of each adverse effect, as well as their predictive factors, reversibility and their use in pregnancy and lactating mothers are covered in this review. Novel data regarding reno-protective effect of telbivudine are also discussed. EXPERT OPINION Use of NA in HBV is generally safe. Uncommon adverse effects can be minimized or detected early if clinicians exercise adequate precautions when using NA for at-risk populations with regular monitoring.

Abstract
BACKGROUND Data comparing the clinical outcomes of telbivudine (LdT) and entecavir (ETV) in elderly patients with chronic hepatitis B are limited. GOALS The aim of the present study was to compare the efficacy and renal safety of LdT and ETV in treatment-naive elderly (≥ 60 years) patients with chronic hepatitis B. METHODS A total of 33 patients treated with LdT were consecutively enrolled in the study. Each patient was matched on the basis of age, sex, and baseline hepatitis B virus (HBV) DNA levels with three to four randomly selected controls treated with ETV. RESULTS Clinical characteristics were comparable between the two groups. Higher cumulative HBeAg-seroconversion rates were observed in the LdT group than in the ETV group after 2 years (50 vs. 20%) and 3 years (50 vs. 26.67%) of treatment (all P<0.0001). Virological response rate at week 24 was significantly lower in the LdT group than it was in the ETV group (54.55 vs. 70.87%, P<0.0001), but no significant difference was noted in long-term cumulative rates of undetectable HBV DNA levels between the two groups (P=0.562). Virological breakthrough occurred in six (18.18%) LdT patients, with no such cases reported in the ETV group (P<0.0001). Antiviral resistance was strongly associated with LdT use and the absence of undetectable HBV DNA at weeks 12 and 24 (P<0.0001). During the study, significant improvement was observed in the estimated glomerular filtration rate and model for end-stage liver disease score in LdT versus ETV group. CONCLUSION LdT has a lower clinical efficacy for viral suppression and a higher risk of antiviral resistance than does ETV. However, LdT resulted in higher HBeAg-seroconversion rates and better renoprotective effects than did ETV.

Abstract
Worldwide, some 240 million people have chronic hepatitis B virus (HBV), with the highest rates of infection in Africa and Asia. Our understanding of the natural history of HBV infection and the potential for therapy of the resultant disease is continuously improving. New data have become available since the previous APASL guidelines for management of HBV infection were published in 2012. The objective of this manuscript is to update the recommendations for the optimal management of chronic HBV infection. The 2015 guidelines were developed by a panel of Asian experts chosen by the APASL. The clinical practice guidelines are based on evidence from existing publications or, if evidence was unavailable, on the experts' personal experience and opinion after deliberations. Manuscripts and abstracts of important meetings published through January 2015 have been evaluated. This guideline covers the full spectrum of care of patients infected with hepatitis B, including new terminology, natural history, screening, vaccination, counseling, diagnosis, assessment of the stage of liver disease, the indications, timing, choice and duration of single or combination of antiviral drugs, screening for HCC, management in special situations like childhood, pregnancy, coinfections, renal impairment and pre- and post-liver transplant, and policy guidelines. However, areas of uncertainty still exist, and clinicians, patients, and public health authorities must therefore continue to make choices on the basis of the evolving evidence. The final clinical practice guidelines and recommendations are presented here, along with the relevant background information.

Abstract
Monotherapy with telbivudine or adefovir can affect estimated the glomerular filtration rate (eGFR). However, only a few studies have assessed changes in eGFR in patients who have chronic hepatitis B (CHB) and are receiving nucleos(t)ide analogue (NA) combination therapy. In our study, we aimed to evaluate the effects of long-term NA combination therapy on eGFR in Chinese CHB patients. This retrospective study included 195 CHB patients. Patient subgroups included those treated with lamivudine plus adefovir (n = 73), telbivudine plus adefovir (n = 51), and entecavir plus adefovir (n = 35); untreated patients (n = 36) served as a control group. After an average follow-up duration of 24 months with combination therapy, analysis of changes in eGFR from baseline values, calculated by the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) and Modification of Diet in Renal Disease (MDRD) formulas, showed decrease by 11.08 and 18.34 mL/min (P < .001), respectively, in the lamivudine plus adefovir group; decrease by 3.73 and 10.04 mL/min (P = .012), respectively, in the entecavir plus adefovir group; and increase by 0.91 and 2.12 mL/min (P = .46), respectively, in the telbivudine plus adefovir group. The eGFR in the telbivudine plus adefovir group was similar to that for the untreated group. The eGFR decreases due to adefovir therapy could be rescued by adding telbivudine, and the eGFR increase due to telbivudine could be compromised by adding adefovir. Adefovir in combination with lamivudine or entecavir therapy was significantly associated with decreased eGFR, but telbivudine could rescue the eGFR decrease that results from adefovir treatment.

Abstract
The development of effective nucleos(t)ide analogs (NAs) against hepatitis B virus (HBV) has improved the outcome of patients with chronic hepatitis B (CHB). This review updates issues related to the management of CHB patients included in special populations. Entecavir (ETV) and tenofovir (TDF) represent the currently recommended first-line NAs in patients with HBV decompensated cirrhosis. The combination of HBV immunoglobulin (usually for a finite duration) and NA is considered the standard of care for prophylaxis against HBV recurrence after liver transplantation. TDF is the best choice for hemodialysis patients and in patients with chronic kidney disease with nucleoside resistance. ETV and telbivudine are the preferred options in naïve renal transplant recipients and with low viremia levels, respectively. All hepatitis B surface antigen (HBsAg)-positive candidates should be treated with NAs before renal transplantation to achieve undetectable HBV DNA at the time of transplantation. Conventional interferon or NAs can also be used in children, on the basis of well-established therapeutic indication. Pregnant women at high risk of perinatal transmission could be treated with lamivudine, telbivudine or TDF in the last trimester of pregnancy. HBsAg-positive patients under immunosuppression should receive NA pre-emptively (regardless of HBV DNA levels) up to 12 mo after its cessation. In HBsAg negative, anti-HBc positive patients under immunosuppression, further studies are needed to form a final conclusion; however, it seems that anti-HBV prophylaxis is justified in such patients with hematological diseases and/or for those receiving rituximab-containing regimens, regardless of their anti-HBs or serum HBV DNA status.
