Manganese inhibits HBV transcription and promotes HBsAg degradation at non-toxic levels

Chronic hepatitis B virus (HBV) infection continues to pose a significant global health challenge. However, therapeutic measures for a cure are lacking in clinical practice. Manganese, an essential trace element, has garnered attention due to its potential to activate innate immune pathways and its significant role in antiviral and antitumor immunity. Yet, the specific impact of manganese on chronic hepatitis B has been largely unexplored. Our research reveals that manganese substantially inhibits HBV replication in hepatocellular carcinoma cells at non-toxic levels. This suppression occurs independently of well-known anti-HBV innate immune pathways, such as the cGAS-STING pathway. Mechanistically, manganese decreases HBV transcription by diminishing the levels of liver-specific transcription factors. Furthermore, it activates the mTOR pathway, enhancing HBsAg ubiquitination through the upregulation of the ubiquitin ligase β-TrCP and increasing proteasome activity via the augmentation of its subunits, leading to a ubiquitin-dependent degradation of HBsAg. Significantly, our study also uncovers a notable clinical correlation between manganese levels and chronic hepatitis B infection. These findings position manganese as a critical element in diminishing HBV replication, offering a new direction in the management of chronic hepatitis B.

Incidence and Predictors of HBsAg Loss in Paediatric Patients With Chronic Hepatitis B Undergoing Antiviral Treatment.

Achieving HBsAg loss is a critical clinical milestone in the management of chronic hepatitis B (CHB) towards the eradication of hepatitis B. However, there are limited researches on the incidence and determinants of HBsAg loss in paediatric CHB patients undergoing antiviral treatment. Therefore, we aimed to analyse the incidence and potential determinants of HBsAg loss in children who suffered from CHB and received antiviral treatment. This retrospective cohort study was performed on paediatric patients with progressive CHB who initiated either monotherapy or combination therapy using interferon/peg-interferon and entecavir. We utilised Cox regression models to evaluate the relationships between HBsAg loss and various determining factors. In total of 306 subjects with an average age of 4.99 years (range 1-15) were identified in this study, of whom 200 (65.4%) were male. After a median follow-up of 26 months, HBsAg loss occurred in 135 participants. The accumulated rate of HBsAg loss was 67.8% at the end of the follow-up evaluation. Multivariate Cox regression analysis revealed that older age (HR = 0.84, 95% CI: 0.79-0.90), female sex (HR = 1.61, 95% CI: 1.13-2.30), baseline HBsAg levels (HR = 0.72, 95% CI: 0.62-0.84), HBsAb positivity (HR = 1.77, 95% CI: 1.20-2.59) and serum bilirubin levels (HR = 0.96, 95% CI: 0.92-0.99) were statistically significant predictors of HBsAg loss. The incidence of HBsAg loss continues to increase in paediatric patients with CHB after antiviral treatment. Age, sex, baseline HBsAg and bilirubin levels and HBsAb positivity are found to be associated with sustained HBsAg loss.

The management of chronic hepatitis B

Given the myriad of available tests, guidelines and treatments, chronic infection with the hepatitis B virus (HBV) can seem daunting for the nonspecialist. However, its prevalence among some of the most vulnerable in society, the stigma surrounding it and its potential to lead to cirrhosis and hepatocellular carcinoma (HCC) make it crucial for the frontline primary care physician to understand.

Insights into the Management of Chronic Hepatitis in Children-From Oxidative Stress to Antioxidant Therapy.

Recent research has generated awareness of the existence of various pathophysiological pathways that contribute to the development of chronic diseases; thus, pro-oxidative factors have been accepted as significant contributors to the emergence of a wide range of diseases, from inflammatory to malignant. Redox homeostasis is especially crucial in liver pathology, as disturbances at this level have been linked to a variety of chronic diseases. Hepatitis is an umbrella term used to describe liver inflammation, which is the foundation of this disease regardless of its cause. Chronic hepatitis produces both oxidative stress generated by hepatocyte inflammation and viral inoculation. The majority of hepatitis in children is caused by a virus, and current studies reveal that 60-80% of cases become chronic, with many young patients still at risk of advancing liver damage. This review intends to emphasize the relevance of understanding these pathological redox pathways, as well as the need to update therapeutic strategies in chronic liver pathology, considering the beneficial effects of antioxidants.

Plasma metabolome analysis for predicting antiviral treatment efficacy in chronic hepatitis B: diagnostic biomarkers and therapeutic insights.

The early and accurate identification of predictive biomarkers for antiviral treatment efficacy remains a significant clinical challenge, particularly in the management of chronic hepatitis B (CHB). This study aimed to assess whether the plasma metabolome could reliably predict the success of antiviral therapy in CHB patients. We conducted a retrospective analysis on 56 treatment-naive CHB patients at the First Affiliated Hospital of Zhejiang University from December 2013 to March 2016. Patients who underwent a 48-week treatment regimen of entecavir (ETV) and interferon-alpha (IFN-α) were randomly assigned to either a discovery cohort (n=29) or a validation cohort (n=27). Based on the outcome of the treatment, patients were classified as HBeAg seroconversion group (High responders, Hrp) or the non-remission group (Low responder, Lrp). Our methodology involved an untargeted analysis of the amine/phenol and carboxylic acid submetabolomes in the CHB patients under treatment, utilizing chemical isotope labeling (CIL) techniques with liquid chromatography-mass spectrometry (LC-MS). Several metabolites were identified as having significant diagnostic potential for distinguishing Hrp from Lrp, with areas under the receiver operating characteristic curve (AUC) exceeding those typical clinical indicators. Notably, four metabolites, namely 2-methyl-3-ketovaleric acid, 2-ketohexanoic acid, 6-oxo-1,4,5,6-tetrahydronicotinic acid, and α-ketoisovaleric acid, demonstrated exceptionally high sensitivity and specificity in both cohorts, nearing 100%. In contrast, the clinical indicators, including HBcAb, log(HBsAg), and HBeAb, demonstrated lower and inconsistent sensitivity and specificity between the discovery and validation cohorts. Using HBcAb as a marker, the sensitivity was 87.5% with 76.9% specificity in the discovery cohort; however, the sensitivity dropped to 46.7% with 91.7% specificity in the validation cohort. Using log(HBsAg), the sensitivity was 84.6% with 69.2% specificity in the discovery cohort, compared to 85.7% sensitivity and 83.3% specificity in the validation cohort. For HBeAb, the separation of Hrp and Lrp had a sensitivity of 87.5% with 69.2% specificity in the discovery cohort, while the validation cohort showed 86.7% sensitivity and 91.7% specificity.

HBsAg Status, Molecular Detection and Therapy Evaluation of Hepatitis B Patient

The management of chronic hepatitis B involves various therapeutic approaches, including nucleotide analogs (NUCs) and pegylated-interferon alpha (peg-IFN), either in isolation or in combination. Reverse transcriptase enzyme is competitively inhibited by NUCs, which effectively suppresses HBV replication and lowers viral load. Concerning their cost-effectiveness, high response rates, low side effects, and oral administration, NUCs are recommended. Prolonged use, particularly of NUCs with a low genetic barrier or as monotherapy, can, however, lead to resistance, long-term safety issues, and the need for ongoing treatment. Physicians and other healthcare professionals are extremely concerned about the emergence of resistance and possible safety concerns related to the long-term use of NUCs. Moreover, the requirement for continuous therapy presents notable obstacles concerning patient adherence, distribution of healthcare resources, and overall economic viability. To clarify these problems and direct the creation of more potent and long-lasting treatment plans for chronic hepatitis B, urgent research is required. Hepatitis B surface antigen (HBsAg) detection is frequently accomplished via the use of the Chemiluminescent Microparticle Immunoassay (CMIA), which is a crucial early serologic marker for screening and diagnosis. Polymerase chain reaction (PCR) molecular testing is employed to confirm the presence of HBsAg. Polymerase Chain Reaction (PCR) was the technique we utilized to verify the outcomes. Twenty-eight of the HBsAg-positive patients at W.Z. Johannes Kupang Hospital had positive PCR results, highlighting the significance of molecular confirmation. The results of this study emphasize the value of precise HBsAg testing and the supplementary function of molecular confirmation in the treatment of patients with chronic hepatitis B. Furthermore, it clarifies the current therapeutic approaches applied to this patient population, highlighting the necessity of customized therapeutic approaches based on each patient's unique profile and potential complications.

Disparities in presentation and management of chronic hepatitis B among Hispanics in a diverse safety net system.

Chronic hepatitis B (HBV) prevalence is highest in foreign-born Asian and African individuals in the US, though Hispanics make up the largest proportion of the immigrant population. Differences in the diagnosis and management of chronic HBV in Hispanics might exist due to the lower awareness of risk. We aim to examine racial/ethnic disparities in the diagnosis, presentation, and immediate management of chronic HBV in a diverse safety net system enriched for Hispanics. In a large urban safety-net hospital system, we retrospectively identified patients with chronic HBV by serological data and categorized them into mutually exclusive self-identified racial/ethnic groups: Hispanics, Asians, Blacks, and Whites. We then examined differences in screening, disease phenotype and severity, follow-up testing, and referral by race/ethnicity. Among 1063 patients, 302 (28%) were Hispanics, 569 (54%) Asians, 161 (15%) Blacks, and 31 (3%) Whites. More Hispanics (30%) were screened in the acute setting (defined as inpatient or emergency department encounters) than Asians (13%), Blacks (17%), or Whites (23%) (p<0.01). Hispanics also had lower rates of follow-up testing after HBV diagnosis than Asians including HBeAg status (43% vs. 60%, p<0.01) and HBV DNA levels (42% vs. 58%, p<0.01) and lower rates of linkage to specialty care (32% vs. 55%, p<0.01). Among those with available testing, however, the presence of immune-active chronic HBV was infrequent and similar across racial/ethnic groups. 25% of Hispanics had cirrhosis at initial presentation, proportionally higher than other groups (p<0.01). Our results underscore the importance of raising chronic HBV awareness and increasing both screening and linkage to care among Hispanic immigrants in addition to the existing risk groups, with the goal of mitigating downstream liver-related complications.

The role of different viral biomarkers on the management of chronic hepatitis B.

Chronic hepatitis B infection is a major public health challenge. With the advancement in technology, various components of the viral cycle can now be measured in the blood to assess viral activity. In this review article, we summarize the relevant data of how antiviral therapies impact viral biomarkers, and discuss their potential implications. Viral nucleic acids including hepatitis B virus (HBV) double-stranded deoxy-ribonucleic acid (DNA) and to a lesser extent, pre-genomic RNA, are readily suppressed by nucleos(t)ide analogues (NUCs). The primary role of these markers include risk prediction for hepatocellular carcinoma (HCC) and risk stratification for partial cure, defined as off-therapy virological control, or functional cure, defined as hepatitis B surface antigen (HBsAg) seroclearance plus undetectable serum HBV DNA for ≥6 months. Viral translational products including hepatitis e antigen, quantitative HBsAg and hepatitis B core-related antigen can be reduced by NUCs and pegylated interferon a. They are important in defining disease phase, delineating treatment endpoints, and predicting clinical outcomes including HCC risk and partial/ functional cure. As the primary outcome of phase III trials in chronic hepatitis B is set as HBsAg seroclearance, appropriate viral biomarkers can potentially inform the efficacy of novel compounds. Early viral biomarker response can help with prioritization of subjects into clinical trials. However, standardization and validation studies would be crucial before viral biomarkers can be broadly implemented in clinical use.

Comparison of patients using lamivudine, entecavir, and tenofovir according to liver fibrosis markers fibrosis-4 and aspartate aminotransferase-to-platelet ratio index scores.

It was intended to assess the efficacy of lamivudine, entecavir, and tenofovir regimens in the management of chronic hepatitis B (CHB) guided by Fibrosis-4 (FIB-4) and aspartate aminotransferase-to-platelet ratio index (APRI) scores. Our study was conducted on patients who applied to the hepatitis outpatient clinic between 2008 and 2015 retrospectively. Lamivudine, entecavir, and tenofovir regimens used in the practice of CHB cases were compared by measuring noninvasive FIB tests. Entirely 199 patients involved in the research were evaluated in three treatment arms; 48 used lamivudine, 46 used entecavir, and 105 used tenofovir. Similar statistical characteristics were observed between research arms regarding age, gender, and alanine aminotransferase normalization by years (P > 0.05). Totally 5 (13.5%) of patients developed Hepatitis B e antigen (HBeAg) seroconversion among 36 HBeAg positivity, and similar statistical features were seen by comparing the groups (P > 0.05). In the entecavir and tenofovir arms, a significant decrease was seen in FIB-4, and APRI index values in the 1st year of treatment (P < 0.001). At the graph curve, a plateau was observed in the APRI test after the 1st year, and a plateau was observed in the FIB-4 test after the 2nd year. Consistent with the study outcome, when we consider FIB regression, tenofovir and entecavir regimens were found more effective than lamivudine. In addition, entecavir was more effective than the other two drugs after the 1st year.

Treatment endpoints for chronic hepatitis D.

Management of chronic hepatitis D (CHD) has entered a new era. In this new era, the virus entry inhibitor bulevirtide has received conditional approval as a treatment for compensated CHD. Three phase 3 studies with two new compounds are ongoing for the treatment of CHD. In this context, surrogate markers of treatment efficacy have been well defined for chronic hepatitis B (CHB) (7) and chronic hepatitis C (8) but not for CHD. The aim of this review is to give a perspective on treatment endpoints in CHD. For this, we took guidance from CHB studies and tried to make suggestions which differed according to finite versus prolonged treatment durations and also took into account the different characteristics of the new compounds.

Chronic hepatitis E: Advancing research and patient care.

The hepatitis E virus (HEV) was initially thought to exclusively cause acute hepatitis. However, the first diagnosis of chronic hepatitis E in transplant recipients in 2008 profoundly changed our understanding of this pathogen. We have now begun to understand that specific HEV genotypes can cause chronic infection in certain immunocompromised populations. Over the past decade, dedicated clinical and experimental research has substantiated knowledge on the epidemiology, transmission routes, pathophysiological mechanisms, diagnosis, clinical features and treatment of chronic HEV infection. Nevertheless, many gaps and major challenges remain, particularly regarding the translation of knowledge into disease prevention and improvement of clinical outcomes. This article aims to highlight the latest developments in the understanding and management of chronic hepatitis E. More importantly, we attempt to identify major knowledge gaps and discuss strategies for further advancing both research and patient care.

Management of Chronic Hepatitis B in HIV-Coinfected Patients.

Hepatitis B virus infection occurs in approximately 7% of people living with HIV (PLWH), with substantial regional variation and higher prevalence among intravenous drug users. Early studies on the natural history of HIV/HBV coinfection demonstrated that in coinfected patients, chronic hepatitis B (CHB) has a more rapid progression than in HBV-monoinfected patients, leading to end-stage liver disease complications, including hepatocellular carcinoma. Therefore, the adequate management of CHB is considered a priority in HIV-coinfected patients. Several guidelines have highlighted this issue and have provided recommendations for preventing and treating HBV infection. This article discusses the management of liver disease in patients with HIV/HBV coinfection and summarizes the current and future therapeutic options for treating chronic hepatitis B in this setting.

Prevalence and management of chronic hepatitis B in pemphigus and pemphigoid patients: New evidence for the safety of rituximab.

Although the treatments of pemphigus and pemphigoid patients have tended toward safer options, patients with chronic infections seem to be still at the risk of infection reactivation when they are exposed to any of immunosuppressive treatments. A retrospective study on 1646 registered pemphigus and pemphigoid patients was conducted between January 2017 and February 2019 and the prevalence of HBV, the association between the treatments, mainly prednisolone and rituximab with HBV reactivation as well as outcomes of patients after management with antiviral therapies were evaluated. From 1646 reviewed patients, 10 (0.60%) patients with chronic HBV were identified. We found a negative correlation between the ALT (p-value<0.001), AST (p-value=0.090), and Pemphigus Disease Area Index (PDAI) (p-value=0.034) and age of patients. At the time points that prednisolone dosage was higher, higher levels of ALT, but no difference in AST levels was noted. The portion of patients with normal ALT was significantly higher (p-value=0.036; OR=2.22) in those who had received rituximab within the previous 6 months (38 of 49; 77.6%) as compared to those who did not (81 of 133; 60.9%). We concluded that avoidance (high dose) systemic corticosteroids in patients with chronic HBV, and using rituximab instead in severe cases benefit this group of patients.
