RESUMO

Asian, Pacific Islander, African, and Caribbean communities in the U.S. are heavily impacted by chronic hepatitis B (HBV) and hepatocellular carcinoma (HCC). Educating these groups about the link between the two diseases is imperative to improve screening rates and health outcomes. This study aims to identify and incorporate preferred mediated communication methods into community-specific educational campaigns which emphasize the connection between the conditions, to promote uptake of prevention and management behaviors for HBV and HCC. Fifteen focus groups and two key informant interviews were conducted with Micronesian, Chinese, Hmong, Nigerian, Ghanaian, Vietnamese, Korean, Somali, Ethiopian, Filipino, Haitian, and Francophone West African communities. Data were analyzed using thematic coding and analysis. Findings demonstrate that all communities preferred materials be offered in both English and native languages and requested that materials highlight the connection between HBV and HCC. Delivery channel preferences and messaging themes varied by group. This study provides insight into community-specific preferences for learning about HBV and HCC. The findings can be used to design culturally and linguistically tailored, multi-platform, health education campaigns to facilitate improved HBV screening and vaccination rates and increase knowledge about HCC risk among highly impacted communities in the U.S.

RESUMO

BACKGROUND: A greater understanding of the determinants of health behavior among those with and at-risk of chronic hepatitis B virus (HBV) infection is needed for effective design and implementation of public health initiatives. AIMS: To determine factors associated with (1) willingness to accept HBV antiviral treatment and (2) satisfaction with provider communication regarding HBV care in a diverse cohort of HBV-infected patients. METHODS: Using a multifaceted model of health behavior, the Health Behavior Framework, we conducted a comprehensive assessment of knowledge, attitudes, beliefs, and barriers to HBV care. RESULTS: We enrolled 510 patients, with mean age 46 years; 53.1% men; and 71.6% Asian or Hawaiian/Pacific Islander. Patients were knowledgeable about HBV infection, but one-fifth did not think that HBV was a treatable disease; over a quarter felt it was so common among family and friends that it did not concern them, and less than half of patients believed they were likely to have liver problems or transmit HBV to others during their lifetime. Perceived susceptibility to disease risk was the only independent predictor of willingness to accept HBV treatment (ß = 0.23, p = 0.0005), and contrary to expectations, having a doctor that speaks the same language was predictive of lower patient satisfaction with provider communication about their HBV care (ß = - 0.65, p < 0.0001). CONCLUSIONS: Patients with greater perceived susceptibility to the health consequences of HBV infection are more likely to accept treatment, and patient-provider language concordance impacts patient satisfaction with communication regarding HBV care in an unexpected direction.

RESUMO

BACKGROUND & AIMS: Although treatment of hepatitis C virus (HCV) infection has improved, the prevalence of alcoholic liver disease (ALD) has been increasing, so we need an updated estimate of the burden and etiology-specific mortality of chronic liver diseases. We studied trends in age-standardized mortality of chronic liver diseases in adults at least 20 years old in the United States from 2007 through 2016. METHODS: We collected data from the US Census and National Center for Health Statistics mortality records and identified individuals with HCV infection, ALD, nonalcoholic fatty liver disease, or hepatitis B virus infection using ICD-10 codes. We obtained temporal mortality rate patterns using joinpoint trend analysis with estimates of annual percentage change (APC). RESULTS: Age-standardized HCV-related mortality increased from 7.17 per 100,000 persons in 2007 to 8.14 per 100,000 persons in 2013, followed by a marked decrease in the time period at which patients began receiving treatment with direct-acting antiviral agents (from 8.09 per 100,000 persons in 2014 to 7.15 per 100,000 persons in 2016). The APC in HCV mortality increased 2.0%/year from 2007 through 2014 but decreased 6.4%/year from 2014 through 2016. In contrast, age-standardized mortality increased for ALD (APC 2.3% from 2007 through 2013 and APC 5.5% from 2013 through 2016) and nonalcoholic fatty liver disease (APC 6.1% from 2007 through 2013 and APC 11.3% from 2013 through 2016). Mortality related to hepatitis B virus decreased steadily from 2007 through 2016, with an average APC of -2.1% (95% CI -3.0 to -1.2). Etiology-based mortality in minority populations was higher. HCV-related mortality (per 100,000 persons) was highest in non-Hispanic blacks (10.28) and whites (6.92), followed by Hispanics (5.94), and lowest in non-Hispanic Asians (2.33). Non-Hispanic Asians had higher mortality for hepatitis B virus infection (2.82 per 100,000 vs 1.02 for non-Hispanic blacks and 0.47 for non-Hispanic whites). CONCLUSION: In our population-based analysis of chronic liver disease mortality in the United States, the decrease in HCV-related mortality coincided with the introduction of direct-acting antiviral therapies, whereas mortality from ALD and nonalcoholic fatty liver disease increased during the same period. Minorities in the United States have disproportionately higher mortality related to chronic liver disease.

RESUMO

Chronic hepatitis B (CHB) is a major infectious disease which threatens people's health around the world. Health-related quality of life (HRQoL) has become an important index for evaluating the treatment and prognosis of patients with CHB. Many studies abroad have shown that the HRQoL of patients with CHB is influenced by various factors. Disease severity, clinical symptoms, and low self-efficacy are important influencing factors for patients' quality of life. Anti-viral therapy, proper physical therapy, or psychological intervention can significantly improve the HRQoL of community CHB patients, and HRQoL is even significantly improved in patients undergoing liver transplantation one year ago. These studies provide valid evidence for antiviral therapy for hepatitis B patients and liver transplantation techniques from the psychological level. At present, there still lacks studies on HRQoL of CHB patients in China. This article summarizes the measurement tools for HRQoL widely used in recent years in China and foreign countries, reviews the research advances in HRQoL in community patients with CHB, and discusses the perspectives for future studies.

RESUMO

BACKGROUND: Language support for linguistic minorities can improve patient safety, clinical outcomes and the quality of health care. Most chronic hepatitis B/C infections in Europe are detected among people born in endemic countries mostly in Africa, Asia and Central/Eastern Europe, groups that may experience language barriers when accessing health care services in their host countries. We investigated availability of interpreters and translated materials for linguistic minority hepatitis B/C patients. We also investigated clinicians' agreement that language barriers are explanations of three scenarios: the low screening uptake of hepatitis B/C screening, the lack of screening in primary care, and why cases do not reach specialist care. METHODS: An online survey was developed, translated and sent to experts in five health care services involved in screening or treating viral hepatitis in six European countries: Germany, Hungary, Italy, the Netherlands, Spain and the United Kingdom (UK). The five areas of health care were: general practice/family medicine, antenatal care, health care for asylum seekers, sexual health and specialist secondary care. We measured availability using a three-point ordinal scale ('very common', 'variable or not routine' and 'rarely or never'). We measured agreement using a five-point Likert scale. RESULTS: We received 238 responses (23% response rate, N = 1026) from representatives in each health care field in each country. Interpreters are common in the UK, the Netherlands and Spain but variable or rare in Germany, Hungary and Italy. Translated materials are rarely/never available in Hungary, Italy and Spain but commonly or variably available in the Netherlands, Germany and the UK. Differing levels of agreement that language barriers explain the three scenarios are seen across the countries. Professionals in countries with most infrequent availability (Hungary and Italy) disagree strongest that language barriers are explanations. CONCLUSIONS: Our findings show pronounced differences between countries in availability of interpreters, differences that mirror socio-cultural value systems of 'difference-sensitive' and 'difference-blindness'. Improved language support is needed given the complex natural history of hepatitis B/C, the recognised barriers to screening and care, and the large undiagnosed burden among (potentially) linguistic minority migrant groups.

RESUMO

Objective: To systemically analyze family burden, quality of life of chronic hepatitis B and C patients in Shanghai and related influencing factors. Methods: A representative sample of chronic hepatitis patients (n=1 478) and their family members (n=1 478) was randomly selected through a multi-stage cluster sampling from 30 communities in 10 districts of Shanghai. One patient and one family member of each family were interviewed using different questionnaires to collect related information. Based on Bronfenbrenner' s ecological systems, psychological measurement, two-level random intercept model and multivariable structural equation model were applied to determine the effects and directions of the factors between life quality of chronic hepatitis patients and family burden. Results: The mean score of quality of life of chronic hepatitis patients in Shanghai was 78.70 ± 13.25, the score of " specific module" was highest and the score of " social function" was lowest. Additionally, the mean score of burden reported by the family members was 12.62±10.74, the score of " financial burden" was highest, and the score of " effect on family member' s health" was lowest. Multivariable structural equation model indicated that eight factors were related with life quality and family burden of patients with chronic hepatitis. Among them, HCV infection, elevated serum alanine aminotransferase level, average monthly cost for patient >3 000 yuan (RMB) and poor health of family members were the direct risk factors for the life quality of the patients as well as family burden. The factor of drinking more than once a week influenced the patients' life quality directly and family burden indirectly. On the contrary, the factors of local household registration, hospitalization and family member's indifferent attitude to hepatitis B vaccination influenced the family burden of the chronic hepatitis patients directly and the life quality of the patients indirectly. Conclusion: The findings could be used in the development of community based management and intervention of chronic hepatitis patients in Shanghai.

RESUMO

Chronic hepatitis B virus (HBV) infection is highly prevalent worldwide and is most often diagnosed through screening efforts. In order to identify the specific ethnic groups at greatest risk, it is necessary to go beyond traditional categories. We conducted a retrospective case series in a primary care clinic serving non-English speaking immigrants to determine the prevalence of HBV among patients of various primary spoken languages (used as a proxy for ethnicity). Among the 1378 patients, the overall prevalence of current infection was 8%. HBV infection was markedly higher among Somali, Oromo and Khmer speakerscompared to other groups. This study illustrates the use of granular language data in describing the serologic profiles of HBV infection among non-English speaking patients in primary care setting. The variations in prevalence by language have implications for public health HBV screening efforts, in addition to suggesting potential risk factors for transmission.

RESUMO

Chronic hepatitis B (CHB) and C (CHC) represent significant public health problems worldwide. Combined, over 7 million persons in the USA are chronically infected with either the hepatitis B or the hepatitis C virus. Although the populations affected by the viruses differ, both CHB and CHC are ideal conditions for preventive screening because of a high prevalence and low rate of diagnosis; an early asymptomatic period; highly sensitive and specific test; and treatments which have been shown to result in improved clinical outcomes including liver-related mortality and hepatocellular carcinoma. Improving healthcare delivery for CHB and CHC requires interventions that will increase screening for the infections, expanded capacity for evaluation and monitoring of the infection, and ultimately improved access to treatment. Many of these interventions may leverage opportunities within electronic health records, but must also address unique social, cultural, and language barriers that may prevent effective implementation of novel interventions. Herein, we will review current knowledge related to strategies employed to improve healthcare systems to reduce disparities in viral hepatitis.

RESUMO

Untreated chronic hepatitis B can lead to liver failure and/or liver cancer. These complications can be avoided through prevention with vaccination or treatment of disease. To inform health policy for the Tibetan community in India, we conducted study of hepatitis B prevalence and treatment needs. We conducted a cross-sectional study over 3 months of 2013. Households were randomly selected for participation via a satellite map; one boarding school and one residential monastery were also included. Participants were asked questions and a whole blood sample was collected for HBsAg assay. Participants with a positive HBsAg result were tested for hepatitis B e antigen, ALT, and AST. Participants with a negative HBsAg result were tested for anti-hepatitis B core antibodies. We recruited 2,769 participants; of which 247 (8.9%) were positive for HBsAg. Participants more likely to have a positive HBsAg result were those born in Tibet (12.4%) and aged 30-59 years old. Of those with a positive HBsAg result, 60.7% were positive for hepatitis B e antigen 7% of whom fit into a likely treatment-needed category; the others fit into management categories requiring repeat ALT testing with or without liver fibrosis assessment. Among participants negative for HBsAg, 52.9% from household sampling had anti-HBc antibodies. We identified a high endemicity of chronic hepatitis B in a Tibetan community in India. Resource appropriate approaches are needed for managing chronic hepatitis B in settings such as this one. J. Med. Virol. 88:1357-1363, 2016. © 2016 Wiley Periodicals, Inc.

RESUMO

BACKGROUND: Immigrant populations are believed to be more frequently infected with hepatitis viruses. However, limited unbiased data are available on immigrants outside of academic centres. Therefore, the aim of this study was to perform large-scale screening for hepatitis markers in primary care centres treating mainly individuals with a migrational background in Germany. METHODS: Between November 2010 and January 2012, we prospectively screened 1313 individuals treated by general practitioners at eight primary care centres in North-western Germany. Patients were eligible if they or their parents were not born in Germany. Serological screening for hepatitis B core protein antibodies, hepatitis B surface antigens (HBsAgs), and anti-hepatitis C virus antibodies was performed in each individual. HBsAg-positive and anti-hepatitis C virus-positive patients were further tested for molecular markers of viral replication. RESULTS: The mean age was 49.1±15.8 years. Of the patients, 45.7% were male; 87.3% had migrated to Germany from the Eastern Mediterranean area and 12.0% from Eastern Europe. Of the patients, 32.5% tested positive for hepatitis B core protein antibodies. HBsAgs were found in 3.6% of patients. Overall, hepatitis B virus DNA was detected in 2.2% of patients. Markers for hepatitis C virus infection were found in an almost similar high frequency (1.9%). Individuals with migrational background showed significant deficits in knowledge on general routes of transmission. CONCLUSION: Hepatitis virus infections are indeed significantly more prevalent in immigrant populations as compared with the general German population. These data underline the importance of introducing screening programs in this particular risk group.

RESUMO

It is paramount to understand the epidemiology of chronic hepatitis B to inform national policies on vaccination and screening/testing as well as cost-effectiveness studies. However, information on the national (Scottish) prevalence of chronic hepatitis B by ethnic group is lacking. To estimate the number of people with chronic hepatitis B in Scotland in 2009 by ethnicity, gender and age, the test data from virology laboratories in the four largest cities in Scotland were combined with estimates of the ethnic distribution of the Scottish population. Ethnicity in both the test data and the Scottish population was derived using a name-based ethnicity classification software (OnoMAP; Publicprofiler Ltd, UK). For 2009, we estimated 8720 [95% confidence interval (CI) 7490-10 230] people aged ⩾15 years were living with chronic hepatitis B infection in Scotland. This corresponds to 0·2% (95% CI 0·17-0·24) of the Scottish population aged ⩾15 years. Although East and South Asians make up a small proportion of the Scottish population, they make up 44% of the infected population. In addition, 75% of those infected were aged 15-44 years with almost 60% male. This study quantifies for the first time on a national level the burden of chronic hepatitis B infection by ethnicity, gender and age. It confirms the importance of promoting and targeting ethnic minority groups for hepatitis B testing.

RESUMO

OBJECTIVE: The number of Australians living with chronic hepatitis B (CHB) is thought to be increasing, as are adverse outcomes including cirrhosis and liver cancer, however, robust, up-to-date estimates of this burden are limited. Contemporary estimates of the prevalence of CHB in Australia are essential to guide appropriate public health and clinical responses. METHODS: This study used census-based methodology attributing risk of CHB by country of birth and Aboriginal and Torres Strait Islander status, augmented with priority risk-group based estimates. Deterministic mathematical modelling was used for comparison and for validation of census-derived estimates. RESULTS: An estimated 218,000 Australians (plausible range 192,000-284,000) are living with CHB, a significant increase over previous estimates. The prevalence derived using mathematical modelling was similar, at 204,000. Notable differences were observed by geographic area in both prevalence and the populations predominantly affected. It is estimated that only 56% of people living with CHB in Australia have been diagnosed and notified. CONCLUSIONS: The prevalence of CHB in Australia is increasing, with 1% of the population now estimated to be affected. The majority of the burden is experienced by people born overseas in endemic areas, with more than 95% of new cases of CHB entering the population through migration. IMPLICATIONS: It is imperative that more attention and greater resources are devoted to addressing CHB in Australia; to increase the proportion of Australians affected who have been diagnosed and who are on treatment, in accordance with the First National Hepatitis B Strategy.

RESUMO

Our goal is to examine the prevalence, risk factors, and disease knowledge of chronic hepatitis B (CHB) among Vietnamese Americans in California. We also examined treatment eligibility and linkage to care among patients who tested positive for CHB. We enrolled 717 subjects from ten different hepatitis B virus (HBV) screening events in five locations from January 2009 to June 2010 in California. HBV status was determined by hepatitis B surface antigen (HBsAg) and antibody. Data were collected by a 36-question survey. A total of 99 patients (13.8 %) had positive HBsAg, especially those aged 31-40 years (23.6 %), and 177 (24.7 %) were still susceptible to HBV infection. A significant proportion of those who were HBsAg positive or still susceptible reported a history of HBV vaccination (10 and 20 %, respectively). Following adjustments for age and sex, significant predictors for HBsAg positivity were lack of healthcare coverage (OR=2.4, p=0.004), having a family history of CHB (OR=2.1, p=0.009), and prior occupational exposure (OR=3.0, p=0.007). Of those who tested positive, 13.3 % met criteria for antiviral therapy, but none had been initiated on treatment. HBV prevalence in Vietnamese Americans in California was high (13.8 %), especially in those between 31 and 40 years of age. Patient disease and treatment knowledge was poor, as were follow-up and management of those found to have CHB and/or have indication for antiviral therapy.

RESUMO

AIM: To compare program costs of chronic hepatitis B (CHB) screening and treatment using Australian and other published CHB treatment guidelines. METHODS: Economic modeling demonstrated that in Australia a strategy of hepatocellular cancer (HCC) prevention in patients with CHB is more cost-effective than current standard care, or HCC screening. Based upon this model, we developed the B positive program to optimize CHB management of Australians born in countries of high CHB prevalence. We estimated CHB program costs using the B positive program algorithm and compared them to estimated costs of using the CHB treatment guidelines published by the Asian-Pacific, American and European Associations for the Study of Liver Disease (APASL, AASLD, EASL) and those suggested by an independent United States hepatology panel. We used a Markov model that factored in the costs of CHB screening and treatment, individualized by viral load and alanine aminotransferase levels, and calculated the relative costs of program components. Costs were discounted by 5% and calculated in Australian dollars (AUD). RESULTS: Using the B positive algorithm, total program costs amount to 13,979,224 AUD, or 9634 AUD per patient. The least costly strategy is based upon using the AASLD guidelines, which would cost 34% less than our B positive algorithm. Using the EASL and the United States Expert Group guidelines would increase program costs by 46%. The largest expenditure relates to the cost of drug treatment (66.9% of total program costs). The contribution of CHB surveillance (20.2%) and HCC screening and surveillance (6.6%) is small--and together they represent only approximately a quarter of the total program costs. CONCLUSION: The significant cost variations in CHB screening and treatment using different guidelines are relevant for clinicians and policy makers involved in designing population-based disease control programs.

RESUMO

Despite a high prevalence of liver disease in Viet Nam, there has been no nationwide approach to the disease and no systematic screening of at-risk individuals. Risk factors include chronic hepatitis B (estimated prevalence of 12%), chronic hepatitis C (at least 2% prevalence), and heavy consumption of alcohol among men. This combination of factors has resulted in liver cancer being the most common cause of cancer death in Viet Nam. There is a general lack of understanding by both the general public and health-care providers about the major risk to health that liver disease represents. We report here the initial steps taken as part of a comprehensive approach to liver disease that will ultimately include nationwide education for health-care providers, health educators, and the public; expansion of nationwide screening for hepatitis B and C followed by hepatitis B virus vaccination or treatment of chronic hepatitis B and/or hepatitis C; education about alcoholic liver disease; long-term surveillance for liver cancer; reduction of infection transmission related to medical, commercial, and personal re-use of contaminated needles, syringes, sharp instruments, razors, and inadequately sterilized medical equipment; and ongoing collection and analysis of data about the prevalence of all forms of liver disease and the results of the expanded screening, vaccination, and treatment programs. We report the beginning results of our pilot hepatitis B screening program. We believe that this comprehensive nationwide approach could substantially reduce the morbidity and mortality from liver disease and greatly lessen the burden in terms of both lives lost and health-care costs.

RESUMO

BACKGROUND: Blood component donations by apheresis has become more common in modern blood transfusion practices. However, apheresis donation still remains less common in China. This study describes the demographic profile and transfusion-transmissible infection (TTI) prevalence among donors making apheresis platelet (AP) donations compared to those making whole blood (WB) donations and the differences among five geographically diverse blood centers in China. STUDY DESIGN AND METHODS: This is a descriptive study using data from all successful donations at the five blood centers in 2008 and 2009. Donor demographic and TTI screening reactive rates were collected for WB and AP donations and blood centers. Logistic regression was used to identify independent factors associated with AP donations. RESULTS: From January 1, 2008, to December 31, 2009, there were 512,594 WB and 26,199 AP donations at five blood centers. AP donations accounted for 4.9% of all donations. AP donations have lower reactive rate than WB donations for hepatitis B virus surface antigen, hepatitis C virus antibodies, human immunodeficiency virus antibodies, and syphilis screening testing. Males, donors older than 25 years old, non-Han donors, and donors with below high school educational level were more likely to make AP donations. The characteristics of AP donations differed among the five Chinese blood centers. CONCLUSION: Our analysis suggests that the characteristics of AP donations in China are different from WB donations and differ among the five Chinese blood centers. Some of the differences are likely due to different recruitment policies. Further studies should be conducted to understand what motivates Chinese blood donors to participate as AP donors.

RESUMO

Compared to any other racial/ethnic group, Asian Americans represent a population disproportionately affected by hepatitis B virus (HBV) infection, a leading cause of liver cancer. Since 2007, the San Francisco Hep B Free (SFHBF) Campaign has been actively creating awareness and education on the importance of screening, testing, and vaccination of HBV among Asian Americans. In order to understand what messages resonated with Asian Americans in San Francisco, key informant interviews with 23 (n = 23) individuals involved in community outreach were conducted. A key finding was the ability of the SFHBF campaign to utilize unique health communication strategies to break the silence and normalize discussions of HBV. In addition, the campaign's approach to using public disclosures and motivating action by emphasizing solutions towards ending HBV proved to resonate with Asian Americans. The findings and lessons learned have implications for not only HBV but other stigmatized health issues in the Asian American community.

RESUMO

BACKGROUND: Community coalitions are increasingly recognized as important strategies for addressing health disparities. By providing the opportunity to pool resources, they provide a means to develop and sustain innovative approaches to affect community health. OBJECTIVES: This article describes the challenges and lessons learned in building the Asian American Hepatitis B Program (AAHBP) coalition to conduct a community-based participatory research (CBPR) initiative to address hepatitis B (HBV) among New York City Asian-American communities. METHODS: Using the stages of coalition development as a framework, a comprehensive assessment of the process of developing and implementing the AAHBP coalition is presented. LESSONS LEARNED: Findings highlight the importance of developing a sound infrastructure and set of processes to foster a greater sense of ownership, shared vision, and investment in the program. CONCLUSION: Grassroots community organizing and campus-community partnerships can be successfully leveraged to address and prevent a significant health disparity in an underserved and diverse community.

RESUMO

BACKGROUND AND AIM: Hepatitis B viral (HBV) infection is the predominant etiology of hepatocellular carcinoma (HCC) in Asia. Our group previously reported a staging system known as the Chinese University Prognostic Index (CUPI) for HCC populations of which HBV infection is the predominant etiology. This study aims to validate CUPI and compare with other published staging systems. METHODS: We analyzed a prospective cohort of patients with newly diagnosed HCC from 2003 to 2005. All patients were staged with CUPI, Barcelona Clinic Liver Cancer Classification (BCLC), Cancer of the Liver Italian Program score (CLIP), tumor-node-metastasis (TNM) and Okuda systems at diagnosis. They were followed with survival data and the performance of each staging system (in terms of homogeneity, discriminatory ability and monotonicity of gradient) were analyzed and compared. RESULTS: A total of 595 patients (80.2% with chronic HBV infection) were analyzed. The median follow-up was 41.4 months and the median survival was 6.6 months. Multivariate analyses identified symptomatic disease, ascites, vascular involvement, Child-Pugh-stage, alpha-fetoprotein and treatment to be the independent prognostic factors. CUPI could identify three groups with statistically significant survival difference (P < 0.0001). Both CUPI and CLIP had the most favorable performance in terms of discriminatory ability, homogeneity and monotonicity. CUPI performed the best in predicting 3-month survival while CLIP performed better in predicting the outcome of 6- and 12-month survival rate. BCLC was inferior to CLIP and CUPI in the overall performance. CONCLUSION: We have validated CUPI in a population composed of predominant HBV-related HCC. CUPI is an appropriate staging system for HBV-related HCC. In patients with advanced HCC, both CUPI and CLIP offer good risk stratification.
