Management Of Chronic Hepatitis B Research Articles

Assessing ChatGPT as a Medical Consultation Assistant for Chronic Hepatitis B: Cross-Language Study of English and Chinese.

Chronic hepatitis B (CHB) imposes substantial economic and social burdens globally. The management of CHB involves intricate monitoring and adherence challenges, particularly in regions like China, where a high prevalence of CHB intersects with health care resource limitations. This study explores the potential of ChatGPT-3.5, an emerging artificial intelligence (AI) assistant, to address these complexities. With notable capabilities in medical education and practice, ChatGPT-3.5's role is examined in managing CHB, particularly in regions with distinct health care landscapes. This study aimed to uncover insights into ChatGPT-3.5's potential and limitations in delivering personalized medical consultation assistance for CHB patients across diverse linguistic contexts. Questions sourced from published guidelines, online CHB communities, and search engines in English and Chinese were refined, translated, and compiled into 96 inquiries. Subsequently, these questions were presented to both ChatGPT-3.5 and ChatGPT-4.0 in independent dialogues. The responses were then evaluated by senior physicians, focusing on informativeness, emotional management, consistency across repeated inquiries, and cautionary statements regarding medical advice. Additionally, a true-or-false questionnaire was employed to further discern the variance in information accuracy for closed questions between ChatGPT-3.5 and ChatGPT-4.0. Over half of the responses (228/370, 61.6%) from ChatGPT-3.5 were considered comprehensive. In contrast, ChatGPT-4.0 exhibited a higher percentage at 74.5% (172/222; P<.001). Notably, superior performance was evident in English, particularly in terms of informativeness and consistency across repeated queries. However, deficiencies were identified in emotional management guidance, with only 3.2% (6/186) in ChatGPT-3.5 and 8.1% (15/154) in ChatGPT-4.0 (P=.04). ChatGPT-3.5 included a disclaimer in 10.8% (24/222) of responses, while ChatGPT-4.0 included a disclaimer in 13.1% (29/222) of responses (P=.46). When responding to true-or-false questions, ChatGPT-4.0 achieved an accuracy rate of 93.3% (168/180), significantly surpassing ChatGPT-3.5's accuracy rate of 65.0% (117/180) (P<.001). In this study, ChatGPT demonstrated basic capabilities as a medical consultation assistant for CHB management. The choice of working language for ChatGPT-3.5 was considered a potential factor influencing its performance, particularly in the use of terminology and colloquial language, and this potentially affects its applicability within specific target populations. However, as an updated model, ChatGPT-4.0 exhibits improved information processing capabilities, overcoming the language impact on information accuracy. This suggests that the implications of model advancement on applications need to be considered when selecting large language models as medical consultation assistants. Given that both models performed inadequately in emotional guidance management, this study highlights the importance of providing specific language training and emotional management strategies when deploying ChatGPT for medical purposes. Furthermore, the tendency of these models to use disclaimers in conversations should be further investigated to understand the impact on patients' experiences in practical applications.

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

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. To investigate the characteristics of CHB in Eastern Ethiopia and assess the efficacy and safety of antiviral treatment. 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. 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. 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.

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 interferon α, 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.

Chronic hepatitis B care in regional Australia: implications for clinical practice and public health policy.

Australia is struggling to meet its National Hepatitis B Strategy care targets, particularly in nonmetropolitan settings. It is vital to engage priority populations and improve their access to recommended care to reach these targets. This retrospective study examined people living with chronic hepatitis B (CHB) in regional North Queensland, Australia, and determined whether their care adhered to current national CHB management guidelines. The analysis aimed to identify gaps in care that might be addressed to improve future outcomes. All individuals referred to the gastroenterology clinic at the Townsville University Hospital in regional North Queensland, Australia, for CHB care between January 2015 and December 2020 were identified. Their linkage to care, engagement in care and receipt of guideline-recommended CHB care were determined. Of 255 individuals, 245 (96%) were linked to care; 108 (42%) remained engaged in care and 86 (38%) were receiving guideline-recommended care in 2021. There were 91/255 (36%) who identified as Indigenous Australians. Indigenous status was the only independent predictor of not being linked to care (odds ratio (OR): 0.13 (95% confidence interval (CI): 0.03-0.60), P = 0.01), not being engaged in care (OR: 0.19 (95% CI: 0.10-0.36), P < 0.0001), not receiving guideline-recommended CHB care (OR: 0.16 (95% CI: 0.08-0.31), P < 0.0001) or not being engaged in a hepatocellular carcinoma surveillance programme (OR: 0.08 (95% CI: 0.02-0.27), P < 0.0001). Current approaches are failing to deliver optimal CHB care to Indigenous Australians in regional North Queensland. Targeted strategies to ensure that Indigenous Australians in the region receive equitable care are urgently needed.

Management of patients with CHB outside the guidelines: Insights from Egyptian cohort with long-term follow-up.

It is alarming that globally, only 2.2% (6.6 million) of patients with chronic hepatitis B (CHB) received treatment in 2019. One contributing factor to this low treatment rate is the complexity and restrictive nature of clinical practice guidelines. Since 1998, we have adopted a "treat-all" approach to patients with CHB. A retrospective study was conducted involving patients with CHB who received treatment from 1998 to 2020 at 2 institutions in Egypt. These patients underwent evaluation through various clinical and laboratory methods, which included testing for liver enzymes and HBV DNA. The study analyzed 1825 patients with HBV, finding that 27.4% had viremia levels under 2000IU/mL. Most (88%) were HBeAg-negative, with 12% positive. A large portion (77.6%) had normal alanine aminotransferase levels, though 5.6% exceeded twice the upper limit of normal. About 14.2% were diagnosed with liver cirrhosis, and 9.6% with F3 stage fibrosis at enrollment. Notably, 2% (25 cases) lost HBsAg over a median of 52 months. Patients with HBV DNA <2000IU/mL had a higher HBsAg loss rate (4.2%) compared to those with levels >2000IU/mL (1.3%). During follow-up, 9.5% (117 patients) experienced decompensation, with a higher incidence in those with HBV DNA <2000IU/mL (16.8%) than those >2000IU/mL (7.1%). HCC developed in 5.2% of patients with lower HBV DNA and 2.6% with higher levels, showing significant differences. Liver-related deaths occurred in 2.8% of the cohort, with a slightly higher rate in those with lower initial HBV DNA levels (3.5% vs. 2.5%). The findings suggest a paradigm shift in CHB management toward early and broader eligibility for antiviral therapy. This could improve patient outcomes and address the global treatment gap in CHB management, especially in regions with high CHB prevalence.

Comparison of architect assay and elecsys HBs Ag II assay in the quantification of hepatitis B surface antigen in chronic HBV patients

Background. Hepatitis B virus (HBV) infection is a global health concern, with an estimated 296 million chronic carriers worldwide. Quantification of hepatitis B surface antigen (HBsAg) is a crucial tool in HBV disease management, providing valuable insights into disease progression and treatment efficacy. Objective. To evaluate the comparative performance of the Abbott Architect HBsAg QT and Roche Elecsys HBsAg II assays in quantifying hepatitis B surface antigen (HBsAg) levels in patients with chronic hepatitis B (CHB). Methods. This prospective study enrolled 60 confirmed CHB patients between February 2021 and November 2021. HBsAg levels were measured using both assays and subsequently log-transformed (log10 IU/mL) for statistical analysis. Interclass correlation coefficient (ICC), Pearson correlation coefficient, and Bland-Altman analyses were employed to assess assay concordance and systematic bias. Results. A statistically significant positive correlation was observed between the Elecsys HBsAg II and Architect HBsAg QT assays for both untreated and treatment-receiving CHB patients (ICC values not specified, p &lt;0.001). Notably, Architect consistently yielded higher HBsAg measurements compared to Elecsys. Conclusion. Both the Elecsys HBsAg II and Architect HBsAg QT assays demonstrate robust correlation in quantifying HBsAg levels in CHB patients. However, the Architect assay exhibits a systematic positive bias relative to Elecsys, which should be considered when interpreting results and making clinical decisions. Both tools provide reliable assessments for HBsAg quantification within CHB management strategies, but it is essential to be aware of potential assay-specific differences.

Racial and Ethnic Disparities in Characteristics and Care Patterns of Chronic Hepatitis B Patients in the United States

Chronic hepatitis B (CHB) disproportionately impacts foreign-born patients and those of Asian or Black race. Given the paucity of data, we aimed to study the impact of race/ethnicity on CHB patient characteristics and management. A retrospective analysis of adult CHB patients using data recorded in the deidentified Optum Clinformatics Data Mart Database (January 2003‒March 2021) was performed. We characterized and examined the rates of receiving adequate treatment evaluation (measuring hepatitis B virus DNA and alanine transaminase) and hepatitis B virus treatment among the racial and ethnic groups. The study cohort included 42,140 patients: age, 51.9 ± 15.1 years; 56.1% male; 47% Asian; 26% White; 11% Black; and 7% Hispanic. Thirty-three percent of White and 48% of Asian patients had an annual household income greater than $100,000 US compared with 16% for Black and 25% for Hispanic patients (P < .001), with similar disparities in educational levels. Approximately one third of White (29.3%), Black (35.1%), and Hispanic (35.4%), and half of Asian (49.9%) patients received adequate evaluation (P < .001). Among patients who met American Association for the Study of Liver Diseases treatment criteria, treatment rates were similar among White (60.8%; P= .09) and Black (62.8%; P= .48), but lower among Hispanic (54.7%; P= .03), as compared with Asian patients (65.4%). On multivariable logistic regression adjusted for age, sex, provider type, viral co-infection, and fatty liver disease, Hispanic patients were less likely to receive treatment (adjusted hazard ratio, 0.69; 95% CI, 0.53‒0.91; P= .01) compared with Asian patients. Compared with Asian CHB patients, non-Asian patients were less likely to undergo adequate evaluation and Hispanic patients were less likely to receive treatment for CHB. Additional efforts are needed to improve CHB management, especially for non-Asian patients.

Gaps and Disparities in Chronic Hepatitis B Monitoring and Treatment in the United States, 2016-2019.

Chronic hepatitis B (CHB) carries an increased risk of death from cirrhosis and hepatocellular carcinoma (HCC). The American Association for the Study of Liver Diseases recommends patients with CHB receive monitoring of disease activity, including ALT, hepatitis B virus (HBV) DNA, hepatitis B e-antigen (HBeAg), and liver imaging for patients who experience an increased risk for HCC. HBV antiviral therapy is recommended for patients with active hepatitis and cirrhosis. Monitoring and treatment of adults with new CHB diagnoses were analyzed using Optum Clinformatics Data Mart Database claims data from January 1, 2016, to December 31, 2019. Among 5978 patients with new CHB diagnosis, only 56% with cirrhosis and 50% without cirrhosis had claims for≥1 ALT and either HBV DNA or HBeAg test, and among patients recommended for HCC surveillance, 82% with cirrhosis and 57% without cirrhosis had claims for≥1 liver imaging within 12 months of diagnosis. Although antiviral treatment is recommended for patients with cirrhosis, only 29% of patients with cirrhosis had≥1 claim for HBV antiviral therapy within 12 months of CHB diagnosis. Multivariable analysis showed patients who were male, Asian, privately insured, or had cirrhosis were more likely (P<0.05) to receive ALT and either HBV DNA or HBeAg tests and HBV antiviral therapy within 12 months of diagnosis. Many patients diagnosed with CHB are not receiving the clinical assessment and treatment recommended. A comprehensive initiative is needed to address the patient, provider, and system-related barriers to improve the clinical management of CHB.

Clinical Profile and Limitations in the Management of HBV Patients Attending Clinic at a District Hospital in Ghana.

Chronic hepatitis B (CHB) is estimated to cause between 500,000 and 1.2 million deaths worldwide every year through cirrhosis and hepatocellular carcinoma (HCC). Liver cirrhosis and HCC are the commonest liver diseases causing death in Ghana. The most critical problem in the management of CHB in sub-Saharan Africa is the high cost of investigations and antiviral drugs. There is scanty information concerning newly diagnosed CHB patients and their management challenges in Ghana. This study sought to determine the clinical characteristics and management challenges of CHB patients in Ghana. Methodology. A prospective cohort study was conducted involving newly diagnosed CHB patients being managed at St. Dominic Hospital. Patient demographic and clinical features were abstracted using a standardized questionnaire. The proportion of patients able to undertake investigations and treatment were determined, and the limitations to standard management were recorded. The performance of APRI score in the diagnosis of cirrhosis was also investigated. Of the 334 patients with newly diagnosed CHB, the median age at diagnosis was 35 (IQR 28-44) years. Less than a quarter (22.2%) were able to undertake viral load testing and 23.4% were eligible for treatment. Of those who were eligible for treatment, only 42.3% were able to initiate treatment. Almost a third of cases (32.1%) reported late with liver-related complications. The sensitivity of APRI score with cut-off value of 2 in the diagnosis of liver cirrhosis was 70.2% and specificity was 97.9%. A high proportion of newly diagnosed CHB patients presented late and with liver-related complications. Majority were not able to afford viral load testing and antiviral medication. Screening of hepatitis B among the general population and inclusion of CHB management in the National Health Insurance Scheme should be encouraged.

Nothing About Me Without Me: Shared Decision-Making in Chronic Hepatitis B

This GSK-sponsored symposium took place at the European Association for the Study of the Liver (EASL) International Liver Congress (ILC) on 23rd June 2022 in London, UK. The symposium was developed in collaboration with external experts, including people directly affected by hepatitis B infection, to help highlight priorities for communications between patients and healthcare professionals (HCPs) to ensure good patient outcomes. The panel members were Mark Douglas, a virologist at Westmead Institute for Medical Research, Sydney, Australia; Ahmed Elsharkawy, a consultant transplant hepatologist at the Queen Elizabeth Hospital in Birmingham, UK; Catherine Freeland, Public Health Programme Director at the Hepatitis B Foundation, Doylestown, Pennsylvania, USA; and Natalia Sadowska, who has chronic hepatitis B (CHB), and is a member of the GSK patient council. The symposium was a conversation between the panel members to help better understand the key patient communication priorities for people with CHB when interacting with their HCPs. Panel members discussed the disconnect between patients and their HCPs in information sharing and treatment decision-making. The symposium also explored the patient journey to diagnosis, patients’ fear of transmitting the virus to others, and the management of CHB in the current therapeutic landscape and the future as a functional cure becomes possible.

Analytical and clinical validation of 3′ RACE RT-qPCR assay for detection and quantification of hepatitis B virus (HBV) serum RNA

BackgroundOver 296 million people worldwide are living with chronic Hepatitis B (CHB) infection who require monitoring of viral activity and disease progression. Serum HBV RNA is a promising new biomarker in CHB management. No standardized method for serum HBV RNA quantification has been established. ObjectivesTo develop and validate, both analytically and clinically, a 3′ RACE RT-qPCR assay for quantification of serum HBV RNA. Study designThe 3′ RACE RT-qPCR method was developed using published primers. The analytical limit of detection and quantification, linearity, inter- and intra-assay repeatability, and clinical specificity and sensitivity were evaluated using synthetic pre-genomic RNA and specimens from various patient populations. Intra- and inter-laboratory ring trials involving three laboratories were completed. ResultsThe 3′ RACE RT-qPCR assay dynamic range is 25 to 108 copies/µL of synthetic RNA. Theoretical and measured serum HBV RNA quantities from a serially diluted sample showed excellent linearity (R2=0.9795). The inter- and intra-assay repeatability were 94.91% and 95.12%, respectively. Clinical specificity and sensitivity were 100% and 90%, respectively, in treated patients. Inter-laboratory analysis demonstrated moderate to high agreement among participating laboratories (κ = 0.581 to 0.867). High agreement was also observed between both operators participating in the intra-laboratory evaluation (κ = 0.867). ConclusionsOur methodology for the quantification of serum HBV RNA is specific and repeatable and employs a biologically relevant RNA standard suitable for medium throughput laboratories. Method standardization is required to facilitate the comparison of studies and better understand the clinical role of this novel biomarker.

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.

Clinical impact and mechanisms of hepatitis B virus infection concurrent with non-alcoholic fatty liver disease.

Chronic hepatitis B (CHB) virus infection is an important threat to global health despite the administration of vaccines and the use of antiviral treatments. In recent years, as the prevalence of obesity and metabolic syndrome has increased, non-alcoholic fatty liver disease (NAFLD) in patients with CHB has become more common. Both diseases can lead to liver fibrosis and even hepatocellular carcinoma, but the risk of dual etiology, outcome, and CHB combined with NAFLD is not fully elucidated. In this review, we assess the overlapping prevalence of NAFLD and CHB, summarize recent studies of clinical and basic research related to potential interactions, and evaluate the progressive changes of treatments for CHB patients with NAFLD. This review increases the understanding of the relationship and mechanisms of interaction between steatosis and hepatitis B virus infection, and it provides new strategies for the future clinical management and treatment of CHB combined with NAFLD.

Real-world tertiary referral centre experience stopping nucleos(t)ide analogue therapy in patients with chronic hepatitis B.

BACKGROUND: Identifying strategies for stopping nucleos(t)ide analogues (NUC) in patients with chronic hepatitis B (CHB) is a major goal in CHB management. Our study describes our tertiary-centre experience stopping nucleos(t)ide analogues (NUC) in CHB. METHODS: We conducted a retrospective cohort study of all individuals with CHB seen at the Calgary Liver Unit between January 2009 and May 2020 who stopped NUC. We collected baseline demographics and HBV lab parameters before and after stopping NUC with results stratified by off-treatment durability. Clinical flare was defined as alanine aminotransferase (ALT) over twice the upper limit of normal and virological flare as HBV DNA >2000 IU/mL. RESULTS: Forty-seven (3.5%) of the 1337 individuals with CHB stopped NUC therapy. During follow-up, six patients (12.8%) restarted NUCs because of a flare. All flares occurred within six months of discontinuation. Median time to restart treatment was 90 days (Q1 65, Q3 133). Upon restarting, all showed suppression of HBV DNA and ALT normalization. Factors associated with restarting NUC therapy included hepatitis B e antigen (HBeAg) positive status at first appointment and longer NUC consolidation therapy. Age, sex, ethnicity, liver stiffness measurement, choice of NUC, and quantitative hepatitis B surface antigen (qHBsAg) level at stopping were not associated with sustained response off-treatment. Six patients had functional cure with HBsAg loss. CONCLUSIONS: Stopping long-term NUC is feasible in HBeAg negative CHB. Hepatic flares can occur despite low levels of qHBsAg. Finite NUC therapy can be considered in eligible patients who are adherent to close monitoring and follow-up, particularly in the first six months after stopping NUC therapy.

Role of Innate Immune Regulatory Genes, FOXP3 and FOS in Chronic Hepatitis B Infection.

Persistence of hepatitis B virus (HBV) infection leading to chronic infection and its sequalae is responsible for over half a million deaths worldwide. The reason for persistence of chronic hepatitis B (CHB) infection is still not clearly understood. An attempt was made to understand the role of immune regulatory genes in CHB in comparison to spontaneously cleared HBV infection. Relative gene expression of 26 genes involved in innate immunity were studied using Real-Time Polymerase Chain Reaction Array. A total of 679 subjects from three different geographical regions of Northeast India (Assam, Arunachal Pradesh, and Tripura) were included in this case-control study. The cases were subdivided into CHB cases with HBeAg(+)(72), CHB with HBeAg(-)(278), spontaneously cleared controls (88), and healthy controls (228). Overall, 28.3% of the subjects had previous exposure with HBV, while 28.6% had protective antibodies IgG/IgM against HBV. There was a statistically higher number of CHB in men (66.4%) compared to women (33.6%) (p = 0.0001). Proto-oncogene FOS has been found to be moderately upregulated in CHB with HBeAg +ve (2.3-fold) and significantly upregulated (4.1-fold upregulation) in hepatocellular carcinoma. Further, FOXP3 was found to be significantly upregulated (3.0-fold, p = 0.01) in CHB with HBeAg (+) compared to spontaneously cleared HBV infection. In conclusion, CHB with HBeAg positivity was found to have disrupted immune response with upregulation of FOS and FOXP3. Thus, early induction of HBeAg seroconversion with interferon-based therapy or oral nucleos(t)ide analogs along with FOS inhibitors can have important clinical implications in the management of CHB and preventing cirrhosis and HCC.

Genetic Associations in Chronic Hepatitis B Infection: Toward Developing Polygenic Risk Scores

Chronic hepatitis B (CHB) infection results in multiple clinical phenotypes of varying severity. One of the critical gaps in CHB management is the lack of a genetic-based tool to aid existing hepatocellular carcinomaand cirrhosis risk stratification models for patients with active CHB. Such individual predictive models for CHB are plagued by an inherent limitation of discriminatory power that clearly indicatesthe need for their improvement. In this article, we highlight genetic association studies in CHB that identified HLA and cytokinegenetic susceptibility loci to CHB. We advance the position that translating CHB genetic susceptibility loci into polygenic risk scoreswill be a welcome addendum to the current arsenal of CHB outcome predictive models. We conclude with comments on hurdles that future research efforts should address within the research enclave of CHB and advocate for increased genetic data representation from sub-Saharan Africa.

Abstract PO-267: Demographic and psychosocial predictors of regular chronic hepatitis B monitoring among Asian Americans

Abstract Background: Asian Americans are 8-13 times more likely to develop liver cancer caused by chronic hepatitis B (CHB) and experience a 60% higher death rate than non-Hispanic whites. Doctor visitation for CHB monitoring every six months is effective to prevent liver cancer. Methods: This study utilized the baseline data from an ongoing randomized controlled clinical trial aimed at improving long-term adherence to CHB monitoring and treatment. The goal was to examine the association of sociodemographic and psychosocial factors with having a doctor's visit for their CHB in the past 12-months. Eligible Asian American CHB patients were recruited from the Greater Philadelphia Area and New York City. Multivariable logistic regression was conducted to test the associations. Results: The analysis sample consists of 240 participants, among which 74% did not have a college degree, 46% had lower than $20,000 annual household income, 72% had limited English proficiency. Multivariable logistic regression showed that a higher hepatitis B (HBV) knowledge score (OR = 1.24, p &amp;lt; 0.01) and having a regular physician (OR = 3.45, p &amp;lt; .05) were significantly associated with a higher chance of having visited a doctor in the past 6 months for their CHB management. Having health insurance (OR = 4.63, p &amp;lt; .05), a higher knowledge score (OR = 1.29, p &amp;lt; .01), and a higher CHB management motivation score (OR = 1.12, p &amp;lt; .001) were associated with a higher chance of having blood work done in the past 6 months; Vietnamese ethnicity (vs Chinese) and having a college degree (vs not) were associated with a lower chance of testing. Conclusion: Our study found that both sociodemographic and psychosocial factors had significant impacts on CHB management, suggesting that addressing barriers to health care and improving CHB patients' psychosocial status would be effective intervention strategies to promote CHB management and liver cancer prevention among vulnerable Asian Americans with CHB.

Abstract PO-035: Knowledge, motivation, and mental health: Factors associated with adherence to Hepatitis B medication among underserved Asian Americans

Abstract Introduction: Chronic Hepatitis B (CHB) Virus disproportionately affects Asian Americans, where they represent 6% of the total United States (U.S.) population but make up 58% of Hepatitis B Virus (HBV)-linked hepatocellular carcinoma (HCC) cases. HBV is the leading risk factor for developing HCC. Vietnamese and Chinese Americans suffer from disproportionate amounts of HBV infections as they represent foreign born immigrants that have come from countries with endemic HBV levels. The consequences of non-adherence to medication among is increased virological failure and a higher risk of disease progression to CHB leading to conditions such as cirrhosis as well as HCC. Understanding what factors contribute to medication adherence can be crucial for providing appropriate support for maintaining long-term treatment adherence and sustaining a virological response through interventions and strategies for high-risk populations affected by HBV. This study aims to examine the sociodemographic and psychosocial predictors of low versus medium/high adherence to medication among a community-based sample of Chinese and Vietnamese HBV infected patients. Methods: Study participants were comprised of 382 Asian American CHB patients, including 298 (78.01%) Chinese Americans and 84 (21.99%) Vietnamese Americans. Study participants were recruited between March 2019 to March 2020 and were enrolled through multiple recruitment approaches in the Greater Philadelphia Area and New York City regions. This presentation reports data from the study baseline survey with measures that included medication adherence measured by the Morisksy Medication Adherence Scale, knowledge regarding HBV diagnosis, prevention and treatment, motivation of HBV medication treatment, self-efficacy about HBV medication treatment, depression, and socioeconomic status. Multivariable logistic regression model was used, controlling for recruitment source and clustering by site. Results: Multivariable logistic regression analysis revealed that with regards to sociodemographic predictors, living longer in the U.S. (OR=4.46; 95% CI: 1.23, 16.14; p=0.023), and greater English proficiency characterized as speaking English well or very well were associated with greater odds of medium/high medication adherence (OR=0.31; 95% CI: 0.10, 0.89; p=0.030). With regards to psychosocial predictors, greater knowledge about HBV diagnosis, prevention, and treatment was associated with greater odds of medication adherence (OR=1.46; 95% CI: 1.16, 1.83, p=0.025). Additionally, greater depression score was associated with lower odds of medium/high medication adherence (OR=0.88; 95% CI: 0.78, 0.98, p=0.025). Conclusion: The study findings suggested a need for intervention regarding medication treatment and tertiary prevention and management of CHB among underserved Asian Americans. Furthermore, the association between depression and medication adherence suggests the need for psychological interventions to enhance mental health outcomes and quality of life to potentially improve or maintain medication adherence.

Chronic hepatitis B management in six South Australian Aboriginal community controlled health services.

Chronic hepatitis B is a significant public health issue; however, there is limited understanding of the engagement in primary health care of Aboriginal people living with chronic hepatitis B (CHB). To better understand the management of CHB, diagnostic reports and case note audits were conducted in six South Australian Aboriginal community controlled health services. The audits covered the initial assessment, CHB monitoring, and hepatocellular carcinoma screening. The initial assessment was reviewed by auditing client clinical records for the first 12months from the date of diagnosis, whereas CHB monitoring and hepatocellular carcinoma screening were determined by auditing a 12-month sample period (January to December 2019). Associations with CHB monitoring were determined using a Chi-squared test and Fisher's exact test P -values, as appropriate. There were 50 current clients with a diagnosis of CHB at the time of the audit (January 2020). Testing was incomplete for the initial assessment, CHB monitoring and hepatocellular carcinoma screening. There were significant associations between the increased likelihood of accessing monitoring and the number of times a person attended an Aboriginal community controlled health service, accessing care in a more remote region, having a documented recall and having a GP management plan containing CHB. Through providing evidence of significant associations between having a recall set and GP management plans with increased uptake of disease monitoring, this study has highlighted areas for improvement in clinical management.

Management of hepatitis B and C in special population.

Chronic viral hepatitis is one of the leading causes of cirrhosis worldwide. Chronic hepatitis B is more common in the Asia-Pacific region due to the larger population and lower screening availability. Hepatitis C predominates in the west due to injection drug abuse. The discovery of (oral) direct-acting antiviral agents (DAAs) has changed the landscape of chronic hepatitis C (CHC) management. Nucleos(t)ide analogs (NUCs) have also changed the approach to the treatment of chronic hepatitis B (CHB). Oral NUCs and DAAs have excellent efficacy and patient acceptance as well as a lower risk of resistance. However, certain populations have no robust data and safety and efficacy of such oral drugs is still evolving. In this review, we provide an overview of the management of CHB and CHC in special populations, such as those with chronic kidney disease, pregnant women, healthcare workers, and those undergoing chemo- or immunosuppressive therapy.
