Risk of hepatitis B virus reactivation in oncological patients treated with tyrosine kinase inhibitors:A case report and literature analysis

Hepatitis B virus(HBV)reactivation(HBVr)represents a severe and potentially life-threatening condition,and preventive measures are available through blood test screening or prophylactic therapy administration.The assessment of HBVr traditionally considers factors such as HBV profile,including hepatitis B surface antigen(HBsAg)and antibody to hepatitis B core antigen,along with type of medication(chemotherapy;immunomodulants).Nevertheless,consideration of possible patient’s underlying tumor and the specific malignancy type(solid or hematologic)plays a crucial role and needs to be assessed for decision-making process.

Antiviral treatment standards for hepatitis B:An urgent need for expansion

The present letter to the editor is related to the review with the title“Past,present,and future of long-term treatment for hepatitis B virus.”Chronic hepatitis B(CHB)represents an important and pressing public health concern.Timely identification and effective antiviral therapy hold the potential to reduce liver-related mortality attributable to chronic infection with hepatitis B virus(HBV)substantially.However,the current global treatment rates for CHB remain conspicuously low,with the excessively stringent treatment criteria advocated by national CHB guidelines being a contributing factor to these low rates.Nevertheless,recent strides in comprehending this malady and the emergence of novel antiviral agents prompt the imperative re-evaluation of treatment standards to extend the sphere of potential beneficiaries.An impending need arises for a novel paradigm for the classification of patients with CHB,the expansion of antiviral treatment eligibility for HBV-infected individuals,and even the streamlining of the diagnostic process for CHB to amplify cost-effectiveness and augment survival prospects.

Chronic hepatitis B virus infection in Eastern Ethiopia:Clinical characteristics and determinants of cirrhosis

BACKGROUND Chronic hepatitis B(CHB)virus infection is a major cause of liver-associated morbidity and mortality,particularly in low-income countries.A better understanding of the epidemiological,clinical,and virological characteristics of CHB will guide appropriate treatment strategies and improve the control and management of CHB in Ethiopia.AIM To investigate the characteristics of CHB in Eastern Ethiopia and assess the efficacy and safety of antiviral treatment.METHODS This cohort study included 193 adults who were human immunodeficiency virus-negative with CHB between June 2016 and December 2019.Baseline assessments included chemistry,serologic,and viral markers.χ^(2) tests,Mann-Whitney U tests,and logistic regression analyses were used to identify the determinants of cirrhosis.Tenofovir disoproxil fumarate(TDF)was initiated using treatment criteria from the Ethiopian CHB pilot program.RESULTS A total of 132 patients(68.4%)were men,with a median age of 30 years[interquartile range(IQR):24-38].At enrollment,60(31.1%)patients had cirrhosis,of whom 35(58.3%)had decompensated cirrhosis.Khat use,hepatitis B envelope antigen positivity,and a high viral load were independently associated with cirrhosis.Additionally,66 patients(33.4%)fulfilled the treatment criteria and 59(30.6%)started TDF.Among 29 patients who completed 24 months of treatment,the median aspartate aminotransferase to platelet ratio index declined from 1.54(IQR:0.66-2.91)to 1.10(IQR:0.75-2.53)(P=0.002),and viral suppression was achieved in 80.9%and 100%of patients after 12 months and 24 months of treatment,respectively.Among the treated patients,12(20.3%)died within the first 6 months of treatment,of whom 8 had decompensated cirrhosis.CONCLUSION This study highlights the high prevalence of cirrhosis,initial mortality,and the efficacy of TDF treatment.Scaling up measures to prevent and control CHB infections in Ethiopia is crucial.

Impact of metabolic dysfunction-associated steatotic liver disease on the efficacy of immunotherapy in patients with chronic hepatitis B-related hepatocellular carcinoma

Objective:To investigate the impact of metabolic dysfunction-associated steatotic liver disease(MASLD)on the efficacy of immune checkpoint inhibitor(ICI)-based therapy in patients with chronic hepatitis B(CHB)-related hepatocellular carcinoma(HCC).Methods:A total of 155 patients with CHB-related HCC who received ICI–based therapy(in the Department of Hepatology,Tianjin Second People’s Hospital and Department of Hepatobiliary Oncology,Tianjin Medical University Cancer Institute&Hospital)between April 2021 and December 2023 were evaluated.Patients were divided into two groups:MASLD concurrent with CHB[MASLD-CHB](n=38),and CHB(n=117).Results:The median progression-free survival(PFS,6.9 months vs.9.3 months;P=0.001),progressive disease(57.89%vs.37.61%;P=0.028),and disease control rate(42.11%vs.62.39%;P=0.028)in the MASLD-CHB group were significantly worse than the CHB group.The median overall survival was not attained.The percentage of CD4+PD1+(17.56%vs.8.89%;P<0.001)and CD8+PD1+T cells(10.50%vs.7.42%;P=0.005)in patient samples from the MASLD-CHB group were significantly higher than the CHB group.Concurrent MASLD[hazard ratio(HR)=1.921;95%CI,1.138–3.245;P=0.015]and alpha-fetoprotein levels after 3 months of treatment(HR=2.412;95%CI,1.360–4.279;P=0.003)were independent risk factors for PFS in all patients.Conclusions:ICI-based therapy in patients with CHB-related HCC and concurrent MASLD resulted in poorer efficacy and shorter PFS compared to patients with CHB-related HCC alone.

Risk of hepatitis B virus reactivation in cancer patients undergoing treatment with tyrosine kinase-inhibitors

This editorial commented on an article in the World Journal of Gastroenterology titled“Risks of Reactivation of Hepatitis B Virus in Oncological Patients Using Tyrosine Kinase-Inhibitors:Case Report and Literature Analysis”by Colapietro et al.In this editorial,we focused on providing a more comprehensive exploration of hepatitis B virus reactivation(HBVr)associated with the usage of tyrosine kinase inhibitors(TKIs).It includes insights into the mechanisms underlying HBV reactivation,the temporal relationship between TKIs and HBV reactivation,and preventive measures.The aim is to understand the need for nucleos(t)ide analogs(NAT)and serial blood tests for early recognition of reactivation and acute liver injury,along with management strategies.TKIs are considered to be an intermediate(1%-10%)of HBVr.Current guidelines stipulate that patients receiving therapy with high or moderate risks of reactivation or recent cancer diagnosis must have at least tested hepatitis B surface antigen,anti-hepatitis B core antigen(HBc),and anti-hepatitis B surface antibody.Anti-HBc screening in highly endemic areas means people with negative tests should be vaccinated against HBV.Nucleoside or nucleotide analogs(NAs)like entecavir(ETV),tenofovir disoproxil fumarate(TDF),and tenofovir alafenamide(TAF)form the basis of HBV reactivation prophylaxis and treatment during immunosuppression.Conversely,lamivudine,telbivudine,and adefovir are generally discouraged due to their reduced antiviral efficacy and higher risk of fostering drug-resistant viral strains.However,these less effective NAs may still be utilized in cases where ETV,TDF,and TAF are not feasible treatment options.

Effectiveness and safety of tenofovir amibufenamide in chronic hepatitis B patients

This letter to the editor relates to the study entitled“Tenofovir amibufenamide vs tenofovir alafenamide for treating chronic hepatitis B:A real-world study”,which was recently published by Peng et al.Hepatitis B virus infection represents a significant health burden worldwide and can lead to cirrhosis and even liver cancer.The antiviral drugs currently used to treat patients with chronic hepatitis B infection still have many side effects,so it is crucial to identify safe and effective drugs to inhibit viral replication.

Recurrence and influencing factors of hepatitis B surface antigen seroclearance induced by peginterferon alpha-based regimens

BACKGROUND The long-term stability of hepatitis B surface antigen(HBsAg)seroclearance following peginterferon alpha(peg-IFN-α)-based therapy has not been extensively studied,leaving the full potential and limitations of this strategy unclear.AIM To assess HBsAg recurrence after seroclearance achieved by peg-IFN-αregimens.METHODS This prospective,multicenter,observational study was conducted from November 2015 to June 2021 at three Chinese hospitals:The Second Affiliated Hospital of Xi’an Jiaotong University,Ankang Central Hospital,and The Affiliated Hospital of Yan’an University.Participants who achieved HBsAg seroclearance following peg-IFN-α-based treatments were monitored every 4-12 weeks post-treatment for hepatitis B virus(HBV)markers,HBV DNA,and liver function.The primary outcome was HBV recurrence,defined as the reemergence of HBsAg,HBV DNA,or both,at least twice within 4-8 weeks of follow-up.RESULTS In total,121 patients who achieved HBsAg seroclearance were enrolled.After a median follow-up of 84.0(48.0,132.0)weeks,four subjects were lost to follow-up.HBsAg recurrence was detected in 16 patients.The cumulative HBsAg recurrence rate in the intention-to-treat population was 15.2%.Multivariate logistic regression analysis demonstrated that consolidation time<12 weeks[odds ratio(OR)=28.044,95%CI:4.525-173.791]and hepatitis B surface antibody disappearance during follow-up(OR=46.445,95%CI:2.571-838.957)were strong predictors of HBsAg recurrence.HBV DNA positivity and decompensation of liver cirrhosis and hepatocellular carcinoma were not observed.CONCLUSION HBsAg seroclearance following peg-IFN-αtreatment was durable over 84 weeks of follow-up with a cumulative recurrence rate of 15.2%.

Effect of viral hepatitis on type 2 diabetes:A Mendelian randomization study

BACKGROUND The effects of viral hepatitis(VH)on type 2 diabetes(T2D)remain controversial.AIM To analyze the causal correlation between different types of VH and T2D using Mendelian randomization(MR).METHODS Single nucleotide polymorphisms of VH,chronic hepatitis B(CHB),chronic hepatitis C(CHC)and T2D were obtained from the BioBank Japan Project,European Bioinformatics Institute,and FinnGen.Inverse variance weighted,MREgger,and weighted median were used to test exposure-outcome associations.The MR-Egger intercept analysis and Cochran’s Q test were used to assess horizontal pleiotropy and heterogeneity,respectively.Leave-one-out sensitivity analysis was used to evaluate the robustness of the MR analysis results.RESULTS The MR analysis showed no significant causal relationship between VH and T2D in Europeans[odds ratio(OR)=1.028;95%confidence interval(CI):0.995-1.062,P=0.101].There was a negative causal association between CHB and T2D among East Asians(OR=0.949;95%CI:0.931-0.968,P<0.001),while there was no significant causal association between CHC and T2D among East Asians(OR=1.018;95%CI:0.959-1.081,P=0.551).Intercept analysis and Cochran’s Q test showed no horizontal pleiotropy or heterogeneity(P>0.05).Sensitivity analysis showed that the results were robust.CONCLUSION Among East Asians,CHB is associated with a reduced T2D risk,but this association is limited by HBV load and cirrhosis.Although VH among Europeans and CHC among East Asians are not associated with the risk of T2D,focusing on blood glucose in patients with CHC is still relevant for the early detection of T2D induced by CHCmediated pathways of hepatic steatosis,liver fibrosis,and cirrhosis.

Evaluating short-term and long-term liver fibrosis improvement in hepatitis C patients after DAA treatment

Despite achieving a high cure rate with the direct-acting antivirals(DAAs)in hepatitis C treatment,further research is needed to identify additional benefits of the DAA therapy.The current study evaluated liver fibrosis improvement in 848 hepatitis C patients treated with DAAs,who also achieved sustained virologic response.By the fibrosis-4(FIB-4)index,patients were categorized based on their baseline fibrosis levels,and the improvement in fibrosis was analyzed in both short-term(9-26 weeks)and long-term(≥36 weeks)follow-up.The results showed a significant decrease in the FIB-4 index,indicating an improvement in liver fibrosis,in 63.0%and 67.6%of the patients during the short-term and long-term follow-up,respectively.Short-term improvement was associated with factors including ribavirin usage,blood cholinesterase levels,alanine transaminase levels,albumin levels,and the baseline FIB-4 index,while long-term improvement was associated with factors such as aspartate transaminase levels,total protein level,and the baseline FIB-4 index.The current study emphasizes the importance of continuous assessment and post-treatment monitoring of liver fibrosis,which will provide crucial insights for enhancing patient care in hepatitis C management.

Liver histological changes in untreated chronic hepatitis B patients in indeterminate phase

BACKGROUND Studies with large size samples on the liver histological changes of indeterminate phase chronic hepatitis B(CHB)patients were not previously conducted.AIM To assess the liver histological changes in the indeterminate phase CHB patients using liver biopsy.METHODS The clinical and laboratory data of 1532 untreated CHB patients were collected,and all patients had least once liver biopsy from January 2015 to December 2021.The significant differences among different phases of CHB infection were compared with t-test,and the risk factors of significant liver histological changes were analyzed by the multivariate logistic regression analysis.RESULTS Among 1532 untreated CHB patients,814(53.13%)patients were in the indeterminate phase.Significant liver histological changes(defined as biopsy score≥G2 and/or≥S2)were found in 488/814(59.95%)CHB patients in the indete-rminate phase.Significant liver histological changes were significant differences among different age,platelets(PLTs),and alanine aminotransferase(ALT)subgroup in indeterminate patient.Multivariate logistic regression analysis indicated that age≥40 years old[adjust odd risk(aOR),1.44;95%confidence interval(CI):1.06-1.97;P=0.02],PLTs≤150×10^(9)/L(aOR,2.99;95%CI:1.85-4.83;P<0.0001),and ALT≥upper limits of normal(aOR,1.48;95%CI:1.08,2.05,P=0.0163)were independent risk factors for significant liver histological changes in CHB patients in the indeterminate phase.CONCLUSION Our results suggested that significant liver histological changes were not rare among the untreated CHB patients in indeterminate phase,and additional strategies are urgently required for the management of these patients.

Elimination of hepatitis B as a public health threat:Addressing the challenge and taking action

Despite the significant efforts made in recent years,the latest data from the World Health Organization indicates that there are substantial challenges in achieving the elimination of hepatitis B virus(HBV)infection by 2030.The article in the World Journal of Hepatology by Ismael et al highlighted the limited accessibility to screening and antiviral treatment for HBV infection in eastern Ethiopia.Therefore,the editorial comments on this article will focus on the current challenges and recent efforts in the prevention and treatment of chronic hepatitis B,particularly emphasizing the expansion of screening and antiviral therapy,as well as feasible strategies to improve accessibility for HBV testing,antiviral therapy,and adherence enhancement.

Chronic hepatitis B:Prevent,diagnose,and treat before the point of no return

Hepatitis B remains a significant global health challenge,contributing to substantial morbidity and mortality.Approximately 254 million people world-wide live with Chronic hepatitis B(CHB),with the majority of cases occurring in sub-Saharan Africa and the Western Pacific regions.Alarmingly,only about 13.4%of the individuals infected with this disease have been diagnosed,and awareness of hepatitis B virus(HBV)infection status is as low as 1%in sub-Saharan Africa.In 2022,CHB led to 1.1 million deaths globally.The World Health Organization(WHO)has set a target of eliminating hepatitis B as a public health concern by 2030;however,this goal appears increasingly unattainable due to multiple challenges.These challenges include low vaccination coverage;a large number of undiagnosed cases;a low proportion of patients eligible for treatment under current guidelines;limited access to healthcare;and the costs associated with lifelong treatment.Treatment of HBV can yield significant clinical benefits within a long window of opportunity.However,the benefits of therapy are markedly diminished when the disease is detected at the advanced cirrhosis stage.This editorial aim to highlight the current challenges in hepatitis care and the necessary steps to achieve the WHO's hepatitis elimination goals for 2030.

Liver stiffness in hepatocellular carcinoma and chronic hepatitis patients:Hepatitis B virus infection and transaminases should be considered

BACKGROUND Liver condition is a crucial prognostic factor for patients with hepatocellular carcinoma(HCC),but a convenient and comprehensive method to assess liver condition is lacking.Liver stiffness(LS)measured by two-dimensional shear wave elastography may help in assessing liver fibrosis and liver condition.Chronic hepatitis B(CHB)is an important risk factor for HCC progression,but LS was found to be less reliable in assessing liver fibrosis following hepatitis viral eradication.We hypothesize that the status of hepatitis virus infection would affect the accuracy of LS in assessing the liver condition.AIM To test the feasibility and impact factors of using LS to assess liver condition in patients with HCC and CHB.METHODS A total of 284 patients were retrospectively recruited and classified into two groups on the basis of serum CHB virus hepatitis B virus(HBV)-DNA levels[HBV-DNA≥100.00 IU/mL as Pos group(n=200)and<100.00 IU/mL as Neg group(n=84)].Correlation analyses and receiver operating characteristic analyses were conducted to evaluate the relationship between LS and liver condition.RESULTS A significant correlation was found between LS and most of the parameters considered to have the ability to evaluate liver condition(P<0.05).When alanine aminotransferase(ALT)concentrations were normal(≤40 U/L),LS was correlated with liver condition indices(P<0.05),but the optimal cutoff of LS to identify a Child-Pugh score of 5 was higher in the Neg group(9.30 kPa)than the Pos group(7.40 kPa).When ALT levels were elevated(>40 U/L),the correlations between LS and liver condition indices were not significant(P>0.05).CONCLUSION LS was significantly correlated with most liver condition indices in patients with CHB and HCC.However,these correlations varied according to differences in HBV-DNA and transaminase concentrations.

Hepatitis B cure:Current situation and prospects

Achievement of a‘clinical cure’in chronic hepatitis B(CHB)implies sustained virological suppression and immunological control over the infection,which is the ideal treatment goal according to domestic and international CHB management guidelines.Clinical practice has shown encouraging results for specific patient cohorts using tailored treatment regimens.These regimens incorporate either nucleos(t)ide analogs,immunomodulatory agents such as pegylated interferonα,or a strategic combination of both,sequentially or concurrently administered.Despite these advancements in the clinical handling of hepatitis B,achieving a clinical cure remains elusive for a considerable subset of patients due to the number of challenges that preclude the realization of optimal treatment outcomes.These include,but are not limited to,the emergence of antiviral resistance,incomplete immune recovery,and the persistence of covalently closed circular DNA.Moreover,the variance in response to interferon therapy and the lack of definitive biomarkers for treatment cessation also contribute to the complexity of achieving a clinical cure.This article briefly overviews the current research progress and existing issues in pursuing a clinical cure for hepatitis B.

Prediction model for hepatitis B e antigen seroconversion in chronic hepatitis B with peginterferon-alfa treated based on a responseguided therapy strategy

BACKGROUND Models for predicting hepatitis B e antigen(HBeAg)seroconversion in patients with HBeAg-positive chronic hepatitis B(CHB)after nucleos(t)ide analog treatment are rare.AIM To establish a simple scoring model based on a response-guided therapy(RGT)strategy for predicting HBeAg seroconversion and hepatitis B surface antigen(HBsAg)clearance.METHODS In this study,75 previously treated patients with HBeAg-positive CHB underwent a 52-week peginterferon-alfa(PEG-IFNα)treatment and a 24-wk follow-up.Logistic regression analysis was used to assess parameters at baseline,week 12,and week 24 to predict HBeAg seroconversion at 24 wk post-treatment.The two best predictors at each time point were used to establish a prediction model for PEG-IFNαtherapy efficacy.Parameters at each time point that met the corresponding optimal cutoff thresholds were scored as 1 or 0.RESULTS The two most meaningful predictors were HBsAg≤1000 IU/mL and HBeAg≤3 S/CO at baseline,HBsAg≤600 IU/mL and HBeAg≤3 S/CO at week 12,and HBsAg≤300 IU/mL and HBeAg≤2 S/CO at week 24.With a total score of 0 vs 2 at baseline,week 12,and week 24,the response rates were 23.8%,15.2%,and 11.1%vs 81.8%,80.0%,and 82.4%,respectively,and the HBsAg clearance rates were 2.4%,3.0%,and 0.0%,vs 54.5%,40.0%,and 41.2%,respectively.CONCLUSION We successfully established a predictive model and diagnosis-treatment process using the RGT strategy to predict HBeAg and HBsAg seroconversion in patients with HBeAg-positive CHB undergoing PEG-IFNαtherapy.

Quantitative hepatitis B core antibody and quantitative hepatitis B surface antigen:Novel viral biomarkers for chronic hepatitis B management

The management of hepatitis B virus(HBV)infection now involves regular and appropriate monitoring of viral activity,disease progression,and treatment response.Traditional HBV infection biomarkers are limited in their ability to predict clinical outcomes or therapeutic effectiveness.Quantitation of HBV core antibodies(qAnti-HBc)is a novel non-invasive biomarker that may help with a variety of diagnostic issues.It was shown to correlate strongly with infection stages,hepatic inflammation and fibrosis,chronic infection exacerbations,and the presence of occult infection.Furthermore,qAnti-HBc levels were shown to be predictive of spontaneous or treatment-induced HBeAg and HBsAg seroclearance,relapse after medication termination,re-infection following liver transplantation,and viral reactivation in the presence of immunosuppression.qAnti-HBc,on the other hand,cannot be relied on as a single diagnostic test to address all problems,and its diagnostic and prognostic potential may be greatly increased when paired with qHBsAg.Commercial qAnti-HBc diagnostic kits are currently not widely available.Because many methodologies are only semi-quantitative,comparing data from various studies and defining universal cut-off values remains difficult.This review focuses on the clinical utility of qAnti-HBc and qHBsAg in chronic hepatitis B management.

Chronic Hepatitis B in Indian Americans: Lack of Screening and Poor Linkage to Care

Background: Chronic hepatitis B (CHB) is a major cause of liver-related morbidity and mortality in the United States (US) and globally. CHB disproportionately affects Asian Americans and many other immigrant minority populations, primarily owing to the high prevalence of CHB in their countries of origin. India is a country with a medium-to-high prevalence of hepatitis B (HB) (>2%) and has over 40 million people infected with hepatitis B virus (HBV), with more than 115,000 deaths annually from HBV-related complications. Indian Americans are one of the largest immigrant populations in the US but remain underdiagnosed and poorly linked to clinical care. We, therefore, assessed the HBV prevalence and evaluated the linkage-to-care (LTC) among Indian Americans to develop strategic plans to reduce the impact of HBV in the US. Methods: Between April 2022 and January 2024, serologic screening and surveys were provided to 328 Indian American adults (age 20 - 80) in New York City. All participants were tested for a triple panel consisting of hepatitis B surface antigen (HBsAg), hepatitis B surface antibody (anti-HBs), and hepatitis B core IgG antibody (anti-HBc). A survey was conducted on the subjects chronically infected with HBV regarding their histories of infection. Self-administered questionnaires were employed to evaluate demographic and epidemiologic characteristics. Results: Of 328 screened and evaluated (246 males and 82 females), 10 (3.0%) were HBV-infected, 222 (67.7%) were susceptible to HBV, and 96 (29.3%) were immune. The prevalence of chronic HBV varied between the age groups: 4.6% (age 20 - 40), 3.4% (age 41 - 60), and 1.7% (age 61 - 80). Of 10 chronically infected, only two subjects had been previously diagnosed but were not engaged in care. Conclusion: HBV disproportionately affects Asian Americans, primarily owing to immigration from parts of the world where the disease is endemic. Indian Americans belong to an intermediate-risk group, with an HBV prevalence of >2%, but remain underdiagnosed and poorly linked to care. Our pilot study on Indian American populations, the first of its kind, demonstrates a 3% prevalence of CHB, none of whom are linked to care. In addition, this population has a high percentage of unimmune subjects, creating a large reservoir for future infection. With the growing population of Indian Americans, our findings can be used to develop community-based strategies for HBV screenings and LTC that target high-risk groups.

Factors Associated with Renal Impairment in Patients on Tenofovir for Chronic Hepatitis B in Yaoundé (Cameroon)

Background: Tenofovir (TFV) is widely used to treat patients with hepatitis B virus (HBV) infection. But kidney abnormalities are the main concern using this drug. Few studies have described the renal impairment due to the TFV in chronic hepatitis B (CHB) in Sub-Saharan Africa. The objective was to evaluate factors associated with renal impairment observed in patients on TFV for CHB. Method: It was a hospital based cross sectional prospective study carried out from June 2023 to July 2023 in Yaoundé (Cameroon) and included any patient treated with TFV for CHB during at least a period of 6 months. For each participant, we collected in the medical report socio-demographic data, clinical data, baseline creatinine, treatment information (type of TFV which was Disoproxil Fumarate (TDF) or Alafenamide (TAF), duration). Then, we collected blood samples to measure serum creatinine and phosphate levels and urine dipstick analysis. Factors associated with renal impairment were assessed with the Odds Ratio. A p value of Results: A total of 60 participants were included. The median age was 44 years [36-55] and median duration of TFV therapy was 17.5 months [11.7-25.7]. The prevalence of reduced eGFR (Conclusion: Kidney function was impaired in some patients receiving TFV for CHB. It should be monitored, particularly after 36 months and for those receiving TDF prodrug.

Community-Based Hepatitis B Campaign in Asian Americans

Chronic hepatitis B (CHB) disproportionately affects minority groups in the US, particularly Asian Americans, with numerous factors contributing to this disparity. Of the 2.4 million people living with chronic HBV in the US, 60% are Asian American. Many are unaware of their status and lack access to proper clinical care, with less than ten percent receiving necessary antiviral treatment. Barriers to screening and care include lack of disease awareness, language and cultural barriers, and financial constraints. Additionally, healthcare providers and systems in the US often overlook the importance of CHB, leading to inadequate care. In response, the Center for Viral Hepatitis (CVH) has implemented a community-based outreach program over the past sixteen years, employing a multifaceted approach involving all sectors of society and various organizations to combat health disparities in CHB. This grassroots campaign has proven highly effective, leveraging CVH’s leadership in spearheading numerous collaborative activities with community members, healthcare professionals, and policymakers. We have summarized the key points of CVH's efforts and their significance in combating CHB-related health disparities. The CHB Screening and Awareness Campaign, tailored to the Asian American community, serves as a successful model for increasing CHB screening, linkage-to-care, and addressing socio-cultural barriers and health literacy. Insights from these outreach programs have guided the development of culturally relevant resources and education initiatives. These findings suggest that such community-driven approaches are essential for addressing health disparities. The strategies and outcomes of CVH’s efforts can inform future health initiatives for other minority communities in the US and globally.

Global trends in hepatitis C-related hepatocellular carcinoma mortality:A public database analysis(1999-2019)

BACKGROUND Hepatitis C is the leading cause of chronic liver disease worldwide and it significantly contributes to the burden of hepatocellular carcinoma(HCC).However,there are marked variations in the incidence and mortality rates of HCC across different geographical regions.With the advent of new widely available treatment modalities,such as direct-acting antivirals,it is becoming increasingly imperative to understand the temporal and geographical trends in HCC mortality associated with Hepatitis C.Furthermore,gender disparities in HCC mortality related to Hepatitis C are a crucial,yet underexplored aspect that adds to the disease's global impact.While some studies shed light on gender-specific trends,there is a lack of comprehensive data on global and regional mortality rates,particularly those highlighting gender disparities.This gap in knowledge hinders the development of targeted interventions and resource allocation strategies.DISCUSSION The results of our study show an overall decline in the mortality rates of patients with hepatitis C-related HCC over the last two decades.Notably,females exhibited a remarkable decrease in mortality compared to males.Regionally,East Asia and the Pacific displayed a significant decline in mortality,while Europe and Central Asia witnessed an upward trend.Latin America and the Caribbean also experienced an increase in mortality rates.However,no significant difference was observed in the Middle East and North Africa.North America exhibited a notable upward trend.South Asia and Sub-Saharan Africa significantly declined throughout the study period.This raises the hope of identifying areas for implementing more targeted resources.Despite some progress,multiple challenges remain in meeting the WHO 2030 goal of eliminating viral hepatitis[24].
