Abstract
OBJECTIVES The natural history of chronic HBV infection (CHB) is generally divided into four phases: HBeAg-positive chronic HBV infection (EPCI) and -hepatitis (EPCH), HBeAg-negative chronic HBV infection (ENCI) and -hepatitis (ENCH). This study aimed to investigate changes in serum quantitative surface antigen (qHBsAg), systemic immune-inflammation index (SII) and systemic inflammatory response index (SIRI) in a large number of CHB patients. METHOD Three hundred seventy-two CHB patients who underwent liver biopsy between January 2015 and February 2020 were evaluated. RESULTS The SII-values were strongly significant between EPCI-EPCH ( P = 0.002), however, there was significant difference between ENCI-ENCH ( P = 0.025). Considering the SIRI results, there was a significant difference between both EPCI-EPCH ( P = 0.009) and ENCI-ENCH ( P = 0.118). In HBeAg-positive patients HBV-DNA, qHBsAg, and SII were found to be predictive ( P = 0.029, P = 0.039, P = 0.027, respectively) while in HBeAg-negative patients, age, AST, HBV-DNA, qHBsAg, SII, and SIRI were found to be predictive ( P = 0.047, P = 0.084, P = <0.001, P = 0.001, P = 0.012, P = 0.002, respectively). In EPCH phase, whereby accuracy rate results of HBV-DNA, qHBsAg, and SII were 75.3%, 73.4%, and 60.4%, respectively, while in the ENCH phase the accuracy rates of age, AST, HBV-DNA, qHBsAg, SII, and SIRI values were 57.8%, 65.6%, 68.3%, 63.8%, 57.3% and 53.2%, respectively. CONCLUSION HBV-DNA, qHBsAg, and SII are predictive in EPCH patients. Age, AST, HBV-DNA, qHBsAg, SII and SIRI are all predictive in ENCH patients. In patients with CHB, we recommend using SII to distinguish between EPCI-EPCH and ENCI-ENCH. Based on its sensitivity and features, we believe that qHBsAg and SII are suitable measuring instruments in discrimination both of EPCI-EPCH and ENCI-ENCH.

Arthrospira Enhances Seroclearance in Patients with Chronic Hepatitis B Receiving Nucleos(t)ide Analogue through Modulation of TNF-α/IFN-γ Profile. Nutrients 2022; 14:2790. [PMID: 35889747 PMCID: PMC9325115 DOI: 10.3390/nu14142790] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2022] [Revised: 06/30/2022] [Accepted: 07/04/2022] [Indexed: 12/12/2022] Open
Abstract
Chronic hepatitis B (CHB) virus infection, causing immune dysfunction and chronic hepatitis, is one of the leading risk factors for hepatocellular cancer. We investigated how Arthrospira affected hepatitis B surface antigen (HBsAg) reduction in CHB patients under continued nucleos(t)ide analogues (NA). Sixty CHB patients who had been receiving NA for at least one year with undetectable HBV DNA were randomized into three groups: control and oral Arthrospira at 3 or 6 g daily add-on therapy groups. Patients were followed up for 6 months. Oral Arthrospira-diet mice were established to investigate the possible immunological mechanism of Arthrospira against HBV. Within 6 months, mean quantitative HBsAg (qHBsAg) decreased in the oral Arthrospira add-on therapy group. Interestingly, interferon gamma (IFN-γ) increased but TNF-α, interleukin 6 (IL-6), hepatic fibrosis, and steatosis decreased in the add-on groups. In mice, Arthrospira enhanced both innate and adaptive immune system, especially natural killer (NK) cell cytotoxicity, B cell activation, and the interleukin 2 (IL-2), IFN-γ immune response. Arthrospira may modulate IL-2- and TNF-α/IFN-γ-mediated B and T cell activation to reduce HBsAg. Also, Arthrospira has the potential to restore immune tolerance and enhance HBsAg seroclearance in CHB patients through promoting T, B, and NK cell activation.

[PMID: 31009126 DOI: 10.1111/jvh.13114] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/09/2019] [Revised: 02/15/2019] [Accepted: 03/18/2019] [Indexed: 12/12/2022]
Abstract
Cessation of nucleos(t)ide analogue (Nuc) therapy in HBeAg-negative patients may increase HBsAg loss rate in patients with sustained remission (SR) and non-retreated clinical relapsers (CR). To investigate and compare the HBsAg kinetics from end of treatment (EOT) to HBsAg loss in these patients, serial serum samples after EOT from 36 SR and 12 CR with HBsAg loss (study group) and an 1:1 matched control who remained HBsAg-seropositive (control group) were assayed retrospectively for quantitative HBsAg (qHBsAg). The results showed that study group SR and CR had comparable EOT features except SR had lower EOT qHBsAg (67.5 vs 350.5 IU/mL; P = 0.02; < 100 IU/mL: 58.3% vs 25%; P = 0.09). All showed gradual qHBsAg decrease then "precipitous HBsAg decline" (>0.5 log10 IU/mL in 1 year) prior to HBsAg loss. Patients with EOT qHBsAg <100 showed earlier (<12 months) "precipitous HBsAg decline" (91.7% vs 58.3%; P = 0.017) and sooner HBsAg loss (5.5 vs 21.9 months; P = 0.026). The control group also showed gradual qHBsAg decrease but less frequent "precipitous HBsAg decline" (39.6% vs 100%; P < 0.001) which occurred later (15.1 vs 5.7 months; P = 0.003) and was less steep (slope -0.6 vs -1.65 log10 IU/mL/year; P < 0.001). HBsAg loss was achieved in 92.9% of the patients with "precipitous HBsAg decline" >0.76 log10 IU/mL in 1 year. In conclusion, both the SR and CR groups showed gradual HBsAg decrease followed by a "precipitous HBsAg decline", which is a prerequisite for HBsAg loss. Lower EOT HBsAg in the SR group and qHBsAg <100 IU/mL may reflect better immune control hence followed by sooner HBsAg loss.

Abstract
Hepatitis B is a clinically important public health issue. Infection leads to hepatocellular carcinoma. Therefore, patients need antiviral therapy for prolonged period to prevent the complication of the disease. Data concerning chronic hepatitis B (CHB) patients with high hepatitis B virus (HBV) DNA are limited. The aim of the study was to check the efficacy of the nucleoside reverse transcriptase inhibitors (tenofovir) in terms of suppression of HBV DNA. The secondary end point in the study is to evaluate trends of predictive variables that predict outcome of treatment. In this specific study, we evaluated 140 CHB male and female patients, of these 110 completed 48 weeks of treatment. On the basis of hepatitis B e antigen (HBeAg), patients were stratified; HBV DNA and hepatitis B surface antigen (HBsAg) levels were measured along with liver function tests. All enrolled patients were given tenofovir disoproxil fumarate 300 mg daily before breakfast. Overall, 69.1% of patients showed virologic response. HBeAg-negative patient group showed 68% viral suppression and HBeAg-positive patient group showed 45.9% over 24 months of treatment, while at 48 months it was shown to be 76.7% and 54.1%, respectively. None of the patients suffered HBsAg loss during the 48 months. Baseline high HBV DNA level was found as a significant predictor of response (OR, 1.9; 95% CI = 1.23-3.9, p = 0.005). None of the patients observed had serious adverse events. Mutations in the RT region of polymerase gene are shown to be associated with resistance to antiviral drugs. Among patients suffering with chronic HBV infection, HBeAg-negative patient group have better virologic response as compared with HBeAg-positive group. Higher concentration of HBV DNA at baseline has negative prediction for sustained viral suppression. The A-B motif interdomain rtL122F mutation was found in nonresponder patients in our study. Another mutation rtN248H observed in E motif considered to have effect on DNA primer grip, which forms part of binding pocket.

Abstract
Serum hepatitis B surface antigen (HBsAg) level has been developed as an important marker to predict treatment outcome recent years. The authors aimed to identify the correlation between quantitative HBsAg and hepatitis B virus (HBV) DNA level in chronic hepatitis B (CHB) patients and explore whether quantitative HBsAg can be used as a surrogate marker of serum HBV DNA for CHB patients. One hundred seventy-three patients were included in this study. Patients were divided into two groups: Hepatitis B e antigen (HBeAg) positive and negative patients. There was a positive correlation between quantitative HBsAg and HBV DNA level in HBeAg positive patients (r = 0.509, P < 0.001) and poor correlation in HBeAg negative patients (r = 0.176, P = 0.096). Interestingly, completely no correlation (r = -0.01, P = 0.994) was found in younger HBeAg negative patients (<40 years old), whereas in older HBeAg negative patients (>40 years old) there is a positive correlation (r = 0.448, P = 0.003). Mean HBsAg titer and Alanine aminotransferase (ALT) level were significantly higher in HBeAg positive group (3.81 log10 IU/mL; 105 IU/mL) than in negative group (2.85 log10 IU/mL; 32 IU/mL) (P < 0.001). We concluded that quantitative HBsAg could reflect HBV DNA level in HBeAg positive patients, but could not surrogate for HBV DNA level in HBeAg negative patients. Our study improves understanding of the relationship between HBsAg titers and HBV DNA levels in CHB patient and may have implications for future treatment algorithms evaluating the HBsAg titers in both HBeAg positive and negative patients.

Abstract
BACKGROUND This study aimed to investigate the relationship between intrahepatic cccDNA and serum HBsAg in chronic Hepatitis B (CHB) patients with undetectable serum HBV DNA during antiviral therapy. METHODS We investigated HBsAg serum levels and their relationship to intrahepatic total cccDNA and HBV DNA in CHB patients with undetectable serum HBV DNA during oral antiviral therapy. Intrahepatic cccDNA and HBV DNA quantitation were performed in the same needle biopsy material, while serum HBsAg, HBeAg and HBV DNA levels were measured in samples drawn on the day of the liver biopsy. RESULTS A total of 90 patients who had a liver biopsy were enrolled, including 80 patients with CHB and 10 patients with liver cirrhosis (LC). All the CHB patients were divided into HBeAg-positive and HBeAg-negative group. By using real-time PCR detection, we found that intrahepatic cccDNA and HBV DNA levels were higher in CHB patients than those in LC patients (Intrahepatic cccDNA: 6.15±1.19 vs. 6.12±0.36, HBV DNA: 7.26±0.49 vs. 5.59±0.45, both P<0.05). Intrahepatic cccDNA level was positively correlated with serum HBsAg in HBeAg-negative (r=0.66, P=0.02) and lower serum HBeAg (≤50S/CO) CHB patients (r=0.47, P=0.03), but not in higher serum HBeAg (>50S/CO) CHB patients (both P>0.05). In HBeAg negative patients, serum HBsAg level was correlated with intrahepatic total HBV DNA level (r=0.52, P=0.006). However, no relationship between HBsAg level and intrahepatic total HBV DNA level was found in HBeAg positive patients (both P>0.05). CONCLUSIONS Serum HBsAg can be used to predict intrahepatic cccDNA and HBV DNA level in CHB patients with low serum HBeAg statues, especially in HBeAg negative patients.

Abstract
BACKGROUND & AIMS Vertical transmission of hepatitis B virus (HBV) can occur despite immunoprophylaxis in mothers with high HBV DNA levels (>5-7 log10 IU/ml). Quantitative hepatitis B surface antigen (qHBsAg) testing could be used as a surrogate marker to identify high viral load carriers, but there is limited data in pregnancy. We conducted a prospective observational study to determine the cost-effectiveness and utility of qHBsAg as a valid surrogate marker of HBV DNA. METHODS Pregnant patients with chronic hepatitis B were recruited from a tertiary referral centre. HBV DNA levels and qHBsAg were assessed in the second to third trimester. Statistical analysis was performed by Spearman's rank correlation and student's t-test. The cost-effectiveness of qHBsAg as compared to HBV DNA testing was calculated. RESULTS Ninety nine women with 103 pregnancies, median age 32 years, 65% Asian, 23% African and 12% other [Hispanic, Caucasian] were enrolled. Overall, 23% (23/99) were HBV e Ag (HBeAg)-positive. A significant correlation between qHBsAg and HBV DNA levels was noted in HBeAg-positive patients (r = 0.79, P < 0.05) but not in HBeAg-negative patients (r = 0.17, P = 0.06). In receiver operating characteristic analysis, the optimal qHBsAg cut-off values for predicting maternal viraemia associated with immunoprophylaxis failure (i.e., HBV DNA ≥7 log10 IU/ml) was 4.3 log10 IU/ml (accuracy 98.7%, sensitivity 94.7%, specificity 94.4%) (95% CI, 97-100%, P < 0.05). Use of HBV DNA as compared to qHBsAg costs approximately $20 000 more per infection prevented. CONCLUSION In resource poor regions, qHBsAg could be used as a more cost-effective marker for high maternal viraemia, and indicate when anti-HBV nucleos/tide analogue therapy should be used to prevent HBV immunoprophylaxis failure.

Abstract
Loss of hepatitis B surface antigen (HBsAg) is considered to reflect the resolution of a hepatitis B virus (HBV) infection. Patient characteristics and various seromarkers were evaluated to characterize factors predicting spontaneous HBsAg loss in a cohort of HBeAg-seronegative patients with presumed chronic HBV infection. Relationships between seromarkers and HBsAg loss were assessed annually and after 6 years using binary logistic regression. Among the 634 participants, 117 (18.45%) cleared HBsAg after 6 years, with a 3.08% annual seroclearance rate. Baseline HBsAg levels and platelet (PLT) counts were predictors of HBsAg seroclearance. The HBsAg level predicted HBsAg seroclearance better than the PLT count (area under the receiver operating characteristic curve (AUROC): HBsAg, 0.965 (95%CI, 0.947-0.980) versus PLT count, 0.617 (95%CI, 0.561-0.669); P < 0.001). A cutoff HBsAg level of 10 IU/ml at baseline predicted spontaneous HBsAg seroclearance at 6 years with a diagnostic accuracy of 93.4%, a sensitivity of 87.2%, a specificity of 94.8%, a positive predictive value of 79.1%, and a negative predictive value of 97.0%. HBsAg seroclearance may occur more commonly than expected. A serum HBsAg level <10 IU/ml and PLT count were accurate predictors of clearance.

Abstract
Despite several studies regarding the correlation between serum HBsAg titers and viral loads, the association remains uncertain. Eighty‐nine individuals were selected randomly from a Chinese cohort of 2,258 subjects infected persistently with hepatitis B virus (HBV) for cross‐sectional and longitudinal analysis. Viral loads of mutant HBV are lower than those of wild type HBV. The serum HBsAg titers correlate positively with viral loads in both HBeAg positive and negative subjects (r = 0.449, P = 0.013; r = 0.300, P = 0.018, respectively). No correlation between serum HBsAg titer and viral loads was found in any of the four phases of chronic HBV infection. The serum HBsAg titers correlate positively with viral loads in the group with wild type sequences of the PreS/S, basal core promoter (BCP), and preC regions of HBV(r = 0.502, P = 0.040). However, the correlation was not seen in the group with mutations in these regions (r = 0.165, P = 0.257). The correlation between HBsAg titers and viral loads was seen in individuals with wild type PreS/S sequences but not in the subgroup with BCP double mutations or PreC stop mutation, although their sequences in the preS/S regions were wild type. All these findings were confirmed by the longitudinal analysis. In conclusion, the correlation between serum HBsAg levels and viral loads may not differ between HBeAg positive and negative individuals but may depend on wild‐type or mutated genomic sequences. Therefore, HBsAg quantitation may be used as a surrogate for viral loads in only wild‐type HBV infections. J. Med. Virol. 87:1351–1360, 2015. © 2015 The Authors.

Abstract
Heme oxygenase‑1 (HO‑1) possesses significant potential as a drug target for hepatitis B, which may be transferable to patient therapy. The aim of the present study was to clarify the dynamic correlation between the hepatitis B virus (HBV) and HO‑1. The levels of HBV replication and expression of HO‑1 were investigated in HepG2.2.15 hepatoma cells following exposure to 5‑50 µM hemin for 1‑6 days. The mRNA expression levels of HO‑1 were then detected using reverse transcription‑quantitative polymerase chain reaction (RT‑qPCR). HBV replication levels were determined by enzyme‑immunoassay and a PCR‑fluorescence quantitation assay. The results of the present study demonstrated that the mRNA expression levels of HO‑1 increased in a dose‑dependent manner in the HepG2.2.15 cells, following exposure to 5‑50 µM hemin. The mRNA expression levels of HO‑1 reached a peak following exposure of the cells to hemin for three days, subsequently the expression of HO‑1 decreased. Following exposure to hemin at an optimal concentration of 50 µM for 1‑6 days, the levels of the hepatitis B surface antigen (HBsAg) and hepatitis B e antigen (HBeAg) in the cells were significantly reduced. This marked reduction in the expression of HBsAg and HBeAg reached its peak on the first day, following which the inhibition weakened as the duration of exposure increased. In addition, the inhibition of HBV DNA replication increased with the a longer duration of exposure. Furthermore, HBV DNA levels were significantly decreased following exposure to hemin for 3‑6 days. In conclusion, the present study demonstrated that induced expression of HO‑1 interfered with HBV replication in a dose and time‑dependent manner, implying that a reduction of the HBV viral load may contribute to upregulation in the expression of HO‑1.

Abstract
Hepatitis B surface antigen (HBsAg) quantification has garnered attention because of its high predictive value in determining treatment responses. The HBsAg quantification assays, such as Architect and Elecsys, are commercially available, and more assays are in development. We aimed to compare the results of the Architect and Elecsys assays with those of a new assay, WTultra. The WTultra HBsAg assay is a sandwich chemiluminescent microplate enzyme immunoassay and provides an alternative choice which is more cost-effective and potentially applicable in developing or resource-constrained countries and areas. A total of 411 serum samples were collected from patients during various phases of chronic hepatitis B (CHB) infection. The samples were assessed using the three assays, and the results were compared and analyzed. The results for the Architect, Elecsys, and WTultra assays were well correlated according to the overall results for the samples (correlation coefficients, rArchitect versus WTultra = 0.936, rArchitect versus Elecsys = 0.952, and rWTultra versus Elecsys = 0.981) and the various infection phases (rArchitect versus WTultra ranging from 0.67 to 0.975, rArchitect versus Elecsys ranging from 0.695 to 0.982, and rWTultra versus Elecsys ranging from 0.877 to 0.99). Additionally, consistent results were observed according to genotype (genotype B: rArchitect versus WTultra = 0.976, rArchitect versus Elecsys = 0.978, and rWTultra versus Elecsys = 0.979; genotype C: rArchitect versus WTultra = 0.950, rArchitect versus Elecsys = 0.963, and rWTultra versus Elecsys = 0.981) and hepatitis B virus (HBV) DNA levels (rArchitect = 0.540, rWTultra = 0.553, and rElecsys = 0.580). In conclusion, the Elecsys and WTultra assays were well correlated with the Architect assay, irrespective of the CHB infection phase or genotype. All of these assays are reliable for HBsAg quantification.

Abstract
BACKGROUND The timing of antiviral therapy cessation in hepatitis B e antigen (HBeAg)-negative patients is controversial. Here, we aimed to investigate the role of HBV DNA and hepatitis B surface antigen (HBsAg) monitoring to predict off-treatment sustained response. METHODS A total of 53 HBeAg-negative chronic hepatitis B patients who received lamivudine for 34 ±23 (range 12-76) months and had lamivudine stopped for 47 ±35 months were studied. Primary outcome was sustained response, defined as HBV DNA≤200 IU/ml, at 12 months post-treatment (SR-12). RESULTS A total of 9 (17%) patients achieved SR-12. HBV DNA at baseline, month 6 and end of treatment had no association with SR-12. HBsAg levels tended to decrease more significantly during treatment among SR-12 responders. At the end of treatment, both HBsAg ≤2 log IU/ml and reduction by >1 log from baseline had sensitivity, specificity, positive and negative predictive values for SR-12 of 78%, 96%, 78% and 96%, respectively. All 5 patients with HBsAg≤2 log IU/ml and reduction >1 log at the end of treatment achieved SR-12 and all 40 patients with HBsAg>2 log IU/ml and reduction ≤1 log did not have SR-12. The cumulative probability of sustained response and HBsAg clearance at 5 years among patients with HBsAg≤2 log IU/ml were 88% and 72%, respectively, that among patients with HBsAg reduction >1 log were 74% and 61%, respectively. CONCLUSIONS Monitoring of HBsAg level can guide the timing of stopping lamivudine in HBeAg-negative chronic hepatitis B.

Abstract
This clinically relevant review focuses on recent findings concerning hepatitis B surface antigen (HBsAg) quantitation in untreated patients and treated patients with chronic hepatitis B. Recent studies and emerging data have shown that both HBsAg and hepatitis B virus (HBV) DNA levels decline during the natural course of a chronic HBV infection; they are lowest in the inactive phase, which is also characterized by the highest HBsAg/HBV DNA ratio. It has been demonstrated that the combined use of HBsAg and HBV DNA levels might help in the identification of true inactive carriers with high accuracy. Retrospective analyses of HBsAg levels in patients undergoing therapy have suggested a role for HBsAg quantitation in monitoring the response to therapy. In comparison with nucleos(t)ide analogues (NAs), interferon-based therapy results in greater overall declines in serum HBsAg levels. A rapid on-treatment decline in HBsAg levels appears to be predictive of a sustained response. With the aid of HBsAg quantitation, it appears that we can anticipate an individualized approach to tailoring the treatment duration. The proposal of early stopping rules for patients not responding to pegylated interferon (according to a lack of any HBsAg decline) represents a step toward a response-guided approach. The development of stopping rules for patients treated with NAs is desirable for reducing the need for lifelong therapy. However, before stopping rules for antiviral therapy can be applied, we need to learn more about the kinetics of HBsAg declines during the natural history of the infection and as a response to therapy so that we can better define the best timing, the relevant HBsAg cutoff levels, and the best ways to apply these rules in clinical practice.
