Objective: To investigate the changes in the cytokine profiles of chronic hepatitis B (CHB) patients undergoing antiviral treatment. Methods: Hepatitis B e antigen (HBeAg)-positive patients were treated with Pegylated interferon (PEG-IFN) and entecavir (ETV). Clinical biochemistry and cytokines were detected at baseline and every 3 months. Results: In all, 200 patients completed 48 weeks of treatment, 100 in the PEG-IFN group and 100 in the ETV group. During 3-6 months of treatment, compared with baseline, the PEG-IFN group showed a significant decrease in interferon-gamma (IFN-γ), interleukin-17A (IL-17A), interleukin-6(IL-6), interleukin-10(IL-10), and transforming growth factor beta (TGF-β) ( Conclusion During antiviral therapy, a change in the cytokine profile occurred; in the aspect of immune control and functional cure, PEG-IFN was significantly better than ETV.

OBJECTIVE: To evaluate the therapeutic effects of entecavir (ETV) and interferon- (IFN-) treatments for 48 weeks for chronic hepatitis B (CHB) in patients with different baseline alanine aminotransferase (ALT) levels. METHODS: We retrospectively analyzed the data of 369 CHB patients receiving ETV and IFN- treatments for 48 weeks. We compared the virological response rates, HBsAg clearance, and HBsAg reduction between the patients receiving ETV and IFN- treatments with different baseline ALT levels[≤ 5×upper limits of normal (ULN) level (subgroup 1), 5-10×ULN (subgroup 2), and > 10× ULN (subgroup 3)]. RESULTS: In patients receiving ETV treatment, the virological response rate was 83.3% in subgroup 1, 91.4% in subgroup 2, and 95.5% in subgroup 3, as compared with 19.7%, 40%, and 42.9% in the 3 subgroups with IFN- treatment, respectively, showing significantly differences both among different subgroups with the same treatment and between the same subgroup with different treatments ( < 0.05). HBeAg clearance rates in the 3 subgroups were 8.3%, 16.7% and 35.5% in patients with ETV treatment and were 1.8%, 41.9%, and 38.1% in patients with IFN- treatment, respectively, showing significant differences among the 3 subgroups with the same treatment ( < 0.05); in the same subgroups with different treatments, the rates differed significantly only between subgroups 2 ( < 0.05). In ETV group, the rate of HBsAg reduction to below 200 IU/ml was 2.5% in subgroup 1 and 13.8% in subgroup 2, showing no significant difference between the two subgroups; in IFN- group, the rates were also similar between subgroups 1 and 2 (30.6% 33.3%, > 0.05); but the rates differed significantly between the same subgroups with different treatments ( < 0.05). CONCLUSIONS In all the subgroups with different baseline ALT levels, ETV treatment for 48 weeks results in significantly higher virological response rates than IFN- treatment in patients with CHB. In patients with a baseline ALT of 5-10 ×ULN, IFN- can result in a higher HBeAg clearance rate than ETV. In patients with comparable baseline ALT level, IFN- more effectively reduces HBsAg level than ETV. The patients with a relatively high baseline ALT level (> 5 × ULN) show better responses to both ETV and IFN- treatment than those with ALT level below 5×ULN. We thus recommend IFN- for patients with a baseline ALT of 5-10×ULN and ETV for patients with a baseline ALT either below 5 × ULN or beyond 10×ULN.

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

<b>OBJECTIVEb>To explore the predictive value of baseline HBsAg level and early response for HBsAg loss in patients with HBeAg-positive chronic hepatitis B during pegylated interferon alpha-2a treatment.

<b>METHODSb>A total of 121 patients with HBeAg-positive chronic hepatitis B who achieved HBsAg loss were enrolled; all patients were treated with PEG-IFNα-2a 180 μg/week. Serum HBV DNA and serological indicators (HBsAg, anti-HBs, HBeAg, and anti-HBe) were determined before and every 3 months during treatment.

<b>RESULTSb>The median treatment time for HBsAg loss was 84 weeks (7-273 weeks), and 74.38% (90 cases) of the patients needed extended treatment (> 48 weeks). The correlation between baseline HBsAg levels and the treatment time of HBsAg loss was significant (B = 14.465, t = 2.342, P = 0.021). Baseline HBsAg levels together with the decline range of HBsAg at 24 weeks significantly correlated with the treatment time of HBsAg loss (B = 29.862, t = 4.890, P = 0.000 and B = 27.993, t = 27.993, P = 0.005).

<b>CONCLUSIONb>Baseline HBsAg levels and extended therapy are critical steps toward HBsAg loss. Baseline HBsAg levels together with early response determined the treatment time of HBsAg loss in patients with HBeAg-positive chronic hepatitis B during pegylated interferon alpha-2a treatment.

Recent studies suggest that liver cirrhosis is reversible after administering oral nucleos(t)ide analogue therapy to patients with hepatitis B virus (HBV) infection. However, few studies have addressed whether esophageal varices can regress after such therapy. We report a case of complete regression of esophageal varices during entecavir therapy in patients with HBV-related liver cirrhosis, suggesting that complications of liver cirrhosis such as esophageal varices can regress after the long-term suppression of HBV replication.

BACKGROUND/AIMS: Tenofovir disoproxil fumarate (TDF) exhibits similar antiviral efficacy against treatment-naïve and lamivudine (LAM)-resistant chronic hepatitis B (CHB). However, there are few clinical reports on the antiviral effects of TDF-LAM combination therapy compared to TDF monotherapy in patients with LAM-resistant CHB. METHODS: We investigated the antiviral efficacy of TDF monotherapy vs. TDF-LAM combination therapy in 103 patients with LAM-resistant CHB. RESULTS: The study subjects were treated with TDF alone (n=40) or TDF-LAM combination therapy (n=63) for ≥6 months. The patients had previously been treated with TDF-based rescue therapy for a median of 30.0 months (range, 8-36 months). A virologic response (VR) was achieved in 99 patients (96.1%): 95.0% (38/40) of patients in the TDF monotherapy group and 96.8% (61/63) of patients in the TDF-LAM combination therapy group. The VR rates were not significantly different between the TDF monotherapy and TDF-LAM combination therapy groups (88.9 vs. 87.3% at month 12, and 94.4 vs. 93.7% at month 24, log-rank p=0.652). Univariate and multivariate analyses revealed that none of the pretreatment factors were significantly associated with VR. CONCLUSIONS: TDF monotherapy was as effective as TDF-LAM combination therapy for maintaining viral suppression in the vast majority of patients with LAM-resistant CHB, which suggests that TDF add-on therapy with LAM is unnecessary.

BACKGROUND/AIMS: The optimal timing for discontinuing oral antiviral therapy in patients with HBeAg-positive chronic hepatitis B (CHB) is unclear. The aim of our study was to investigate sustained remission after stopping antiviral therapy in patients with HBeAg-positive CHB. METHODS: We analyzed the medical records of 58 patients who were HBeAg-positive and had discontinued antiviral therapy. Antiviral therapy was discontinued after HBeAg seroconversion and HBV DNA negativity for 6-12 months with consolidation therapy. Virologic relapse was defined as an increase in serum HBV DNA >2,000 IU/mL. RESULTS: No difference was observed between the virologic non-relapse and virologic relapse groups in baseline HBV DNA level (p=0.441) or duration of seroconversion (p=0.070). Time-to-undetectable HBV DNA during treatment was shorter in the virologic non-relapse group (29 patients) compared to the relapse group (29 patients) (4.9+/-2.6 vs. 13.2+/-12.7 months; p<0.01). Cumulative relapse rates were 12.7 in month 3, 32.7 in month 6, 47.3 in month 12, and 52.7% in month 18. We determined by multivariate analysis that the consolidation period (> or =18 months, p=0.020) and early virologic response (HBV DNA <20 IU/mL) at six months during antiviral therapy (p=0.017) were significant predictors for sustained remission. CONCLUSIONS: A consolidation period of at least 18 months and early virological response at six months during antiviral therapy were associated with sustained remission in patients with HBeAg-positive CHB after treatment.

BACKGROUND/AIMS: It remains to be determined whether switching from adefovir (ADV) to tenofovir (TDF) provides better virological outcomes in patients exhibiting suboptimal responses to ADV plus nucleoside analogue (ADV+NA) therapy for NA-resistant chronic hepatitis B (CHB). METHODS: In this prospective trial, patients who showed partial responses (defined as serum hepatitis B virus [HBV] DNA >60 IU/mL) to ADV+NA therapy for NA resistance were randomly allocated to receive TDF plus NA (TDF+NA group, n=16) or to continue their current therapy (ADV+NA group, n=16). The primary end point was the proportion of patients with complete virological response (CVR, defined as serum HBV DNA <60 IU/mL) at 48 weeks. RESULTS: The median age was 52 years (16 men), and 28 were positive for hepatitis B e antigen (HBeAg). The baseline characteristics did not differ significantly between the two groups. The proportion with CVR was significantly higher in the TDF+NA group than in the ADV+NA group at 24 weeks (81.3% vs. 25.0%, P=0.001) and 48 weeks (87.5% vs. 37.5%, P=0.002). Furthermore, a decrease in the serum HBV DNA level of >2log10 IU/mL was more likely in the TDF+NA group at both 24 and 48 weeks (68.8% vs. 56.3%, P=0.014 vs. 81.3% vs. 56.3%, P=0.001, respectively). During the follow-up, the rate of HBeAg seroconversion was higher in the TDF+NA group than the ADV+NA group (12.5% vs. 6.25%, P=0.640), as was that for the hepatitis B surface antigen (6.25% vs. 0%, P=0.080). No serious adverse events due to antiviral agents occurred. CONCLUSIONS: In patients exhibiting suboptimal responses to ADV+NA therapy for NA-resistant CHB, switching from ADV to TDF might provide better virological outcomes.

BACKGROUND/AIMS: Clear indicators for stopping antiviral therapy in chronic hepatitis B (CHB) patients are not yet available. Since the level of hepatitis B surface antigen (HBsAg) is correlated with covalently closed circular DNA, the HBsAg titer might be a good indicator of the off-treatment response. This study aimed to determine the relationship between the HBsAg titer and the entecavir (ETV) off-treatment response. METHODS: This study analyzed 44 consecutive CHB patients (age, 44.6±11.4 years, mean±SD; men, 63.6%; positive hepatitis B envelope antigen (HBeAg) at baseline, 56.8%; HBV DNA level, 6.8±1.3 log₁₀ IU/mL) treated with ETV for a sufficient duration and in whom treatment was discontinued after HBsAg levels were measured. A virological relapse was defined as an increase in serum HBV DNA level of >2000 IU/mL, and a clinical relapse was defined as a virological relapse with a biochemical flare, defined as an increase in the serum alanine aminotransferase level of >2 × upper limit of normal. RESULTS: After stopping ETV, virological relapse and clinical relapse were observed in 32 and 24 patients, respectively, during 20.8±19.9 months of follow-up. The cumulative incidence rates of virological relapse were 36.2% and 66.2%, respectively, at 6 and 12 months, and those of clinical relapse were 14.3% and 42.3%. The off-treatment HBsAg level was an independent factor associated with clinical relapse (hazard ratio, 2.251; 95% confidence interval, 1.076–4.706; P=0.031). When patients were grouped according to off-treatment HBsAg levels, clinical relapse did not occur in patients with an off-treatment HBsAg level of ≤2 log10 IU/mL (n=5), while the incidence rates of clinical relapse at 12 months after off-treatment were 28.4% and 55.7% in patients with off-treatment HBsAg levels of >2 and ≤3 log₁₀ IU/mL (n=11) and >3 log₁₀ IU/mL (n=28), respectively. CONCLUSION: The off-treatment HBsAg level is closely related to clinical relapse after treatment cessation. A serum HBsAg level of <2 log₁₀ IU/mL is an excellent predictor of a sustained off-treatment response in CHB patients who have received ETV for a sufficient duration.

<b>OBJECTIVEb>To observe the correlation between constitution of yin deficiency syndrome (YDS) and polymorphism of HLA-DQA1/treatment response of Peg-lFNalpha therapy in HBeAg positive chronic hepatitis B (CHB) patients, and to explore constitution of Chinese medicine (CM) in response of interferon therapy.

<b>METHODSb>Totally 120 HBeAg positive CHB patients who were treated with Peg-IFNalpha were enrolled, and assigned to YDS group (59 cases) and non-YDS group (61 cases) according to classification of CM constitutions. All patients were subcutaneously injected with Peg-IFNalpha-2b (1.0 microg/kg body weight) or Peg-IFNalpha-2a (180 microg), once per week. Effective efficacy was primarily judged when complete response (CR) or partial response (PR) was obtained at month 6. Those with CR or PR completed 1 year therapeutic course. HLA-DQA1 gene types were detected by polymerase chain reaction sequence specific primers (PCR-SSP). The distribution difference of CM constitutions in patients with CR or PR and their inter-group HLA-DQA1 allele frequency were compared.

<b>RESULTSb>Different treatment responses of Peg-IFNalpha were observed in CHB patients of two different CM constitutions. The ratio of CR + PR was 61.0% (36/59) in YDS group, obviously lower than that in NYDS group [78.7% (48/61), P < 0. 05]. Patients with CR had a lower allele frequency of HLA-DQA1 * 0501 than those with no-response [14.8% (8/54) vs. 30.6% (22/72)] with statistical difference (P < 0.05). Patients with CR had a higher allele frequency of HLA-DQA1 * 0601 than those with no-response [18.5% (10/54) vs. 5.6% (4/72)] with statistical difference (P < 0.05). The allele frequency of HLA-DQA1 * 0301 was lower in YDS group than in non-YDS group [2. 5% (3/118) vs. 9.8% (12/122)] with statistical difference (P < 0.05). The allele frequency of HLA-DQA1 * 0501 was higher in YDS group than in non-YDS group [33.9% (40/118) vs. 18.9% (23/122)] with statistical difference (P < 0.05). Yet statistical significance was lost after adjustment (Pc > 0.05 for both).

<b>CONCLUSIONSb>Both constitutions of CM and HLA-DQA1 gene polymorphism af- fect HBeAg positive CHB patients' response to Peg-INFalpha. Constitutions of YDS and HLA-DQA1 * 0501 was not favorable to response, their association needed to be further studied.
