Trends in Mortality Related to Hepatitis B and C from 1990 to 2019 in the Western Pacific Region.

Background/Aims: : This study aimed to analyze the trends in mortality attributed to hepatitis B and C around the Western Pacific region from 1990 to 2019. Methods: : We used data from the Global Burden of Disease Study for a systematic analysis. The deaths related to hepatitis B and C were analyzed by age, sex, year, risk factors, geographical location, and Socio-demographic Index (SDI). Results: : From 1990 to 2019, the annual total deaths from hepatitis B decreased from 0.266 to 0.210 million and those from hepatitis C increased from 0.119 to 0.142 million in the Western Pacific region. The age-standardized mortality rate (ASMR) of hepatitis B and C decreased by 63.5% and 48.0%, respectively. The declines in the ASMR related to hepatitis B and C were only detected in 12 and two Western Pacific countries, respectively. As the major risk factors, the contribution of alcohol use to hepatitis B deaths was 52% and drug use to hepatitis C was 80%. In males and females, the ASMR attributed to hepatitis B decreased by 61% and 71%, respectively, and the ASMR attributed to hepatitis C decreased by 43% and 55%, respectively. The association between SDI and ASMRs suggested that hepatitis B and C, respectively, showed an overall decline and stable trends as the SDI improved in the Western Pacific region. Conclusions: : Although the mortality rate from hepatitis B and C decreased from 1990 to 2019, notable variation was observed among 27 Western Pacific countries. Efforts targeting hepatitis B and C prevention and treatment are still required in this region, especially for the pandemic countries.

Costs of viral hepatitis B in the Republic of Korea, 2002-2015.

The Republic of Korea has a high prevalence of hepatitis B virus (HBV) infection, and the policies concerning costly antiviral medication have been revised recently. However, in the past 10 years, no related research on costs has been conducted. The objective of this study was to estimate the economic burden of viral hepatitis B and determine the trend of changes in its costs between 2002 and 2015. Claims data from the National Health Insurance Service were used. To identify viral hepatitis B cases, the ICD-10th code B16, B17.0, B18.0 and B18.1 were used based on a primary diagnosis. This study was conducted from a societal perspective regarding both direct and indirect costs. Annual costs were adjusted for inflation by calculations based on the 2015 costs. The number of patients with viral hepatitis B increased from 213 758 in 2002 to 342 672 in 2015. The total socio-economic costs increased from 127.1 million USD in 2002 to 459.1 million USD in 2015, mainly due to the increase in pharmaceutical costs, which accounted for the largest proportion of total costs since 2009-220.5 million USD in 2015, which was ~15 times higher than that in 2002. The healthcare costs for viral hepatitis B accounted for 0.13% of the national health expenditure in 2002, increasing to 0.31% in 2015. The economic burden of viral hepatitis B has increased in the Republic of Korea. It is therefore essential to reduce the healthcare costs of HBV infection by establishing an effective management policy.

The impact of socioeconomic status on outcomes in hepatocellular carcinoma: Inferences from primary insurance.

BACKGROUND: To investigate the impact of insurance status on outcomes in patients with hepatocellular carcinoma (HCC). METHODS: Patients diagnosed with HCC in the cancer registry from 2005 to 2016 were retrospectively stratified by insurance group. Overall survival was assessed via Kaplan-Meier curves and Cox proportional hazard models including potential confounders in multivariable analyses. RESULTS: Seven hundred and sixty-nine patients met inclusion criteria (median age 63 years, 78.8% male, 65.9% Caucasian). 44.5% had private insurance (n = 342), 29.1% had Medicare (n = 224), and 26.4% had Medicaid (n = 203). At diagnosis, Medicaid patients had higher rates of Child-Pugh B (32.0%) and C disease (23.6%) vs Medicare (28.6% and 9.8%) and private insurance (26.9% and 6.7%, P < 0.0001) and higher MELD scores (median 11.0) vs Medicare (9.0) and private insurance (9.0, P = 0.0266). Across insurance groups, patients had similar distribution of American Joint Committee on Cancer stage, tumor size, and multifocal tumor burden. Patients with private insurance had the highest survival (median OS 21.9 months) vs Medicare (17.7 months) and Medicaid (13.0 months, overall P = 0.0061). On univariate analysis, Medicaid patients demonstrated decreased survival vs private insurance (HR 1.40, 95% CI: 1.146-1.715, P = 0.0011). After adjustment for liver disease factors, this survival difference lost statistical significance (Medicaid vs private insurance, HR 1.02, 95% CI: 0.819-1.266, P = 0.8596). CONCLUSION: Medicaid was associated with advanced liver disease at HCC diagnosis; however, insurance status is not an independent predictor of HCC survival.

Changing trends in the disease burden of primary liver cancer caused by specific etiologies in China.

BACKGROUND: Liver cancer is a commonly diagnosed malignancy in China. The etiologies of liver cancer are widely known, although studies on temporal trends in liver cancer caused by specific etiologies are rare. METHODS: Data on the incidence and mortality of liver cancer were retrieved from the Global Burden of Diseases Study 2017. The estimated annual percentage change (EAPC) was used to quantify temporal trends in the age-standardized incidence rate (ASIR) and the age-standardized mortality rate (ASMR) of liver cancer from 1990 to 2017. RESULTS: Nationwide, the number of incident cases of liver cancer increased from 258 000 in 1990 to 515 900 in 2017. The ASIR decreased from 27.16 per 100 000 to 26.04 per 100 000 during this period, with an EAPC of -0.64 (95% confidence interval [CI] -0.84, -0.44). The number of deaths increased from 245 300 in 1990 to 418 200 in 2017, and the ASMR decreased from 26.72 to 21.30 (EAPC = -1.16, 95% CI -1.35, -0.97). The most pronounced decreases in the ASIR and ASMR were observed in liver cancer due to hepatitis B and in people aged 15-49 years. CONCLUSIONS: Since the extensive efforts for prevention of hepatitis B virus infection, the incidence of liver cancer due to hepatitis B has significantly decreased. However, liver cancer due to hepatitis C, NASH, and other causes remains a major public health concern. Additional preventive strategies tailored to liver cancer are needed to further reduce its disease burden in China.

Hepatitis B care pathway in Saudi Arabia: Current situation, gaps and actions.

Hepatitis B virus (HBV) infection remains a public health problem worldwide. In this review, we aim to assess the current situation of the HBV care pathway in the Kingdom of Saudi Arabia (KSA), identify gaps/barriers therein, and recommend initiatives to be taken to improve the management of such patients. Towards this end, a literature search was conducted in PubMed and free Internet searches. Interviews with individuals and focus group discussions were held with HBV experts in KSA. Although significant improvements have been made in the past 30 years in KSA in terms of the decline in prevalence (currently estimated to be around 1.3%), the morbidity and mortality related to the disease have not shown a parallel decline. This makes HBV an important public health concern. Furthermore, poor disease awareness, low diagnosis rates, and nonadherence to therapy amplify the disease burden. There are several mandated national screening structures present; however, established protocols for those who test positive and subsequent linkage-to-care are inadequate. In the absence of a virologic cure, a concerted effort should be made to provide safe and effective lifelong treatment. This review provides recommendations to reduce the HBV disease burden in the Saudi population.

Liver cirrhosis mortality at national and provincial levels in Iran between 1990 and 2015: A meta regression analysis.

BACKGROUND: Liver cirrhosis mortality number has increased over the last decades. We aimed to estimate the liver cirrhosis mortality rate and its trends for the first time by sex, age, geographical distribution, and cause in Iran. METHOD: Iranian Death Registration System, along with demographic (Complete and Summary Birth History, Maternal Age Cohort and Period methods) and statistical methods (Spatio-temporal and Gaussian process regression models) were used to address the incompleteness and misclassification and uncertainty of death registration system to estimate annual cirrhosis mortality rate. Percentages of deaths were proportionally redistributed into cirrhosis due to hepatitis B, C and alcohol use based on the data from the Global Burden of Disease (GBD) 2010 study. RESULTS: Liver cirrhosis mortality in elder patients was 12 times higher than that in younger patients at national level in 2015. Over the 26 years, liver cirrhosis mortality in males has increased more than that in females. Plus, the percentage of change in age adjusted mortality rate at provincial levels varied between decreases of 64.53% to nearly 17% increase. Mortality rate has increased until 2002 and then decreased until 2015.The province with highest mortality rate in 2015 has nearly two times greater rate compare to the lowest. More than 60% of liver cirrhosis mortality cases at national level are caused by hepatitis B and C infection. The rate of hepatitis B mortality is four times more than that from hepatitis C. CONCLUSION: This study demonstrated an increasing and then decreasing pattern in cirrhosis mortality that could be due to national vaccination of hepatitis B program. However monitoring, early detection and treatment of risk factors of cirrhosis, mainly in high risk age groups and regions are essential. Cirrhosis mortality could be diminished by using new non-invasive methods of cirrhosis screening, hepatitis B vaccination, definite treatment of hepatitis C.

Accelerating the elimination of viral hepatitis: a Lancet Gastroenterology & Hepatology Commission.

Viral hepatitis is a major public health threat and a leading cause of death worldwide. Annual mortality from viral hepatitis is similar to that of other major infectious diseases such as HIV and tuberculosis. Highly effective prevention measures and treatments have made the global elimination of viral hepatitis a realistic goal, endorsed by all WHO member states. Ambitious targets call for a global reduction in hepatitis-related mortality of 65% and a 90% reduction in new infections by 2030. This Commission draws together a wide range of expertise to appraise the current global situation and to identify priorities globally, regionally, and nationally needed to accelerate progress. We identify 20 heavily burdened countries that account for over 75% of the global burden of viral hepatitis. Key recommendations include a greater focus on national progress towards elimination with support given, if necessary, through innovative financing measures to ensure elimination programmes are fully funded by 2020. In addition to further measures to improve access to vaccination and treatment, greater attention needs to be paid to access to affordable, high-quality diagnostics if testing is to reach the levels needed to achieve elimination goals. Simplified, decentralised models of care removing requirements for specialised prescribing will be required to reach those in need, together with sustained efforts to tackle stigma and discrimination. We identify key examples of the progress that has already been made in many countries throughout the world, demonstrating that sustained and coordinated efforts can be successful in achieving the WHO elimination goals.

Independent Predictors of Mortality and Resource Utilization in Viral Hepatitis Related Hepatocellular Carcinoma.

INTRODUCTION: Hepatitis B (HBV) and C viruses (HCV) are important causes of hepatocellular carcinoma (HCC). Our aim was to assess mortality and resource utilization of patients with HCC-related to HBV and HCV. MATERIAL AND METHODS: National Cancer Institute's Surveillance, Epidemiology and End Results (SEER)-Medicare linked database (2001-2009) was used. Medicare claims included patient demographic information, diagnoses, treatment, procedures, ICD-9 codes, service dates, payments, coverage status, survival data, carrier claims, and Medicare Provider Analysis and Review (MEDPAR) data. HCC related to HBV/HCV and non-cancer controls with HBV/HCV were included. Pair-wise comparisons were made by t-tests and chi-square tests. Logistic regression models to estimate odds ratios (ORs) with 95% confidence intervals (CIs) were used. RESULTS: We included 2,711 cases of HCC (518 HBV, 2,193 HCV-related) and 5,130 non-cancer controls (1,321 HBV, 3,809 HCV). Between 2001-2009, HCC cases related to HBV and HCV increased. Compared to controls, HBV and HCV patients with HCC were older, more likely to be male (73.2% vs 48.9% and 57.1% vs. 50.5%), die within one-year (49.3% vs. 20.3% and 52.2% vs. 19.2%), have decompensated cirrhosis (44.8% vs. 6.9% and 53.9% vs. 10.4%) and have higher inpatient ($60.471 vs. $47.223 and $56.033 vs. $41.005) and outpatient charges ($3,840 vs. $3,328 and $3,251 vs. $2,096) (all P < 0.05). In two separate multivariate analyses, independent predictors of one-year mortality were older age, being male and the presence of decompensated cirrhosis. CONCLUSIONS: The rate of viral hepatitis-related HCC is increasing. Mortality and resource utilization related to HBV and HCV-related HCC is substantial.

Cost-effectiveness analysis of antiviral therapy in patients with advanced hepatitis B virus-related hepatocellular carcinoma treated with sorafenib.

BACKGROUND AND AIM: Antiviral therapy has been demonstrated to significantly improve the survival in patients with advanced hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC). The aim of the study was to investigate the cost-effectiveness of antiviral therapy in patients with advanced HBV-related HCC treated with sorafenib. METHODS: To conduct the analysis, a Markov model comprising three health states (progression-free survival, progressive disease, and death) was created. The efficacy data were derived from medical records. Cost data were collected based on the Chinese national drug prices. Utility data came from the previously published studies. One-way sensitivity analyses as well as probabilistic sensitivity analyses were performed to explore model uncertainties. RESULTS: In the base-case analysis, addition of antiviral therapy to sorafenib generated an effectiveness of 0.68 quality-adjusted life years (QALYs) at a cost of $25 026.04, while sorafenib monotherapy gained an effectiveness of 0.42 QALYs at a cost of $20 249.64. The incremental cost-effectiveness ratio (ICER) was $18 370.77/QALY for antiviral therapy group versus non-antiviral therapy group. On the other hand, the ICER between the two groups in patients with high or low HBV-DNA load, with or without cirrhosis, normal or elevated alanine aminotransferase/aspartate aminotransferase were $16 613.97/QALY, $19 774.16/QALY, $14 587.66/QALY, $19 873.84/QALY, $17 947.07/QALY, and $18 785.58/QALY, respectively. CONCLUSIONS: Based on the cost-effectiveness threshold ($20 301.00/QALY in China), addition of antiviral therapy to sorafenib is considered to be a cost-effective option compared with sorafenib monotherapy in patients with advanced HBV-related HCC in China from the patient's perspective.

The Economic Burden of Hepatitis A, B, and C in South Korea.

The prevalence of hepatitis in South Korea is relatively high compared to that in other high-income countries. For this reason, viral hepatitis infection not only affects the population's health, but also impacts national healthcare costs. This study was performed in order to estimate the individual economic costs of the hepatitis A, B, and C viruses as well as to determine, using nationally representative data, the trends in South Korea with respect to these viruses during the 2008-2011 period. The study found that the prevalence of hepatitis A had decreased, but those of hepatitis B and C had increased overall. The mortality rate of hepatitis C was higher than that of the other two types. The mortality rate of hepatitis B had changed little, whereas that of hepatitis C had risen. The total cost of hepatitis A had decreased, from US $62.2 million to US $45.7 million, although a notable exception occurred in 2009, when the cost was US $126.6 million. Conversely, the total cost of hepatitis B had increased rapidly during the same period, from US $501.4 million to US $607.8 million. Finally, the total cost of hepatitis C had also increased from US $63.9 million to US $90.7 million. The direct costs of hepatitis A, B, and C were estimated to account for approximately 35.5%, 46.6%, and 58.0% of the total, respectively. These findings demonstrate the economic burden associated with hepatitis A, B, and C, and demonstrate the need to establish an effective prevention and management policy for future planning in South Korea.

Change in fibrosis score as a predictor of mortality among HIV-infected patients with viral hepatitis.

Noninvasive markers of liver fibrosis, measured at baseline, have been shown to predict liver-related mortality. It remains unknown if a change in the value of the scores over time predicts mortality in patients with HIV and viral hepatitis. In this retrospective study, survival in HIV/hepatitis B virus (HBV; n = 67), HIV/hepatitis C virus (HCV; n = 43), and HIV/HBV/HCV (n = 41) patients was examined using Kaplan-Meier life table analysis. Aspartate aminotransferase (AST)-to-platelet ratio index (APRI) and FIB-4 scores, two noninvasive markers of liver fibrosis, were calculated at baseline and at last available clinical follow-up to determine the change in fibrosis score. Factors associated with mortality were assessed by Cox proportional hazards, including the change in the noninvasive marker score between the two time points. All-cause mortality was determined by Social Security Death Index and chart review. Sixty-seven were coinfected with HIV/HBV, 43 with HIV/HCV, and 41 were triply infected (HIV/HBV/HCV). Kaplan-Meier analysis showed similar survival for the three groups at 7 years of follow-up (p = 0.10). However, median length of follow-up was lower in HIV/HCV (60.5; range 0-102) compared to HIV/HBV (75.7; 12.3-126.5) and HIV/HBV/HCV (80.0; 2.7-123) months, respectively, p = 0.02. Baseline fibrosis score (p = 0.002), an increase in the value for noninvasive measurements for fibrosis (p < 0.001), and the presence of HIV/HCV coinfection (p = 0.041) were each associated with higher risk for mortality. Baseline fibrosis score (p = 0.03) and an increase in FIB-4 score (p = 0.05) were independent predictors of all-cause mortality, but liver-related mortality was not evaluated. In this study, baseline fibrosis score was predictive of 7-year all-cause mortality. Further studies are needed in a prospective cohort to evaluate the predictive value of monitoring changes in fibrosis scores over time to predict mortality in patients with viral hepatitis.

Use of hepatitis B vaccination for adults with diabetes mellitus: recommendations of the Advisory Committee on Immunization Practices (ACIP).

Hepatitis B virus (HBV) causes acute and chronic infection of the liver leading to substantial morbidity and mortality. In the United States, since 1996, a total of 29 outbreaks of HBV infection in one or multiple long-term-care (LTC) facilities, including nursing homes and assisted-living facilities, were reported to CDC; of these, 25 involved adults with diabetes receiving assisted blood glucose monitoring. These outbreaks prompted the Hepatitis Vaccines Work Group of the Advisory Committee on Immunization Practices (ACIP) to evaluate the risk for HBV infection among all adults with diagnosed diabetes. The Work Group reviewed HBV infection-related morbidity and mortality and the effectiveness of implementing infection prevention and control measures. The strength of scientific evidence regarding protection was evaluated using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) methodology,* and safety, values, and cost-effectiveness were incorporated into a recommendation using the GRADE system. Based on the Work Group findings, on October 25, 2011, ACIP recommended that all previously unvaccinated adults aged 19 through 59 years with diabetes mellitus (type 1 and type 2) be vaccinated against hepatitis B as soon as possible after a diagnosis of diabetes is made (recommendation category A). Data on the risk for hepatitis B among adults aged ≥60 years are less robust. Therefore, ACIP recommended that unvaccinated adults aged ≥60 years with diabetes may be vaccinated at the discretion of the treating clinician after assessing their risk and the likelihood of an adequate immune response to vaccination (recommendation category B). This report summarizes these recommendations and provides the rationale used by ACIP to inform their decision making.

Economic evaluation of infant and adolescent hepatitis B vaccination in the UK.

A Markov model of hepatitis B virus (HBV) disease progression in the UK estimated that 81% of predicted HBV-associated morbidity and mortality could be prevented by universal infant vaccination at a cost of approximately £ 260,000 per QALY gained. Universal adolescent vaccination would be less effective (45% prevented) and less cost-effective (£ 493,000 per QALY gained). Higher HBV incidence rates in males and intermediate/high risk ethnic populations meant it was approximately 3 times more cost-effective to vaccinate these groups. At current vaccine costs a selective infant vaccination programme, based on vaccinating intermediate/high risk ethnic populations would not be considered cost effective. The threshold cost per vaccinated child at which the programme would be considered cost-effective was investigated. Universal infant vaccination would be cost-effective if the average cost of vaccinating each child against HBV, including vaccine and administration costs of all doses, was less than £ 4.09. Given the low cost of vaccination required to make a universal programme cost-effective the most feasible policy in the UK would be to use a suitably priced combined vaccine that included the other antigens in the current infant vaccination schedule.

Trends of acute hepatitis B hospitalizations, comorbidities, fatality rate, and costs associated with the hospitalization in Spain (2001-2006).

INTRODUCTION: The objective of this study is to analyze data related to hospitalization, comorbidities, fatality rate, average stays, and costs associated with hospitalized cases of acute hepatitis B in Spain, during 2001-2006. METHODS: A retrospective study to analyze the characteristics of acute hepatitis B patients admitted to Spanish hospitals was performed using the minimum basic data set. Costs were calculated using the diagnosis-related groups for the disease. RESULTS: The total number of hospitalized patients diagnosed with acute hepatitis B was 2160, of which 73.8% were diagnosed in men. The highest rate corresponds to the group aged 20-39 years (2.33/100 000 inhabitants). Ninety deaths (4.2%) were reported out of the total hospitalized patients. The average hospital stay was 10 days. The trends in the rate of hospitalized acute hepatitis B cases were not statistically significant. There were no differences found in the average length of stay or in the cost during the study period. The estimated total cost was 7 451 098 euros. CONCLUSION: The rate of hospitalized acute hepatitis B patients in Spain did not change during the 2001-2006 period. Having an adequate surveillance system and continuing with the universal immunization and risk group programs, and health education, remain a high priority.

[Estimation on disease burden related to hepatitis B virus infection in Shandong province of China].

OBJECTIVE: To comprehensively measure the burden of hepatitis B, liver cirrhosis and liver cancer in Shandong province, using disability-adjusted life years (DALYs) to estimate the disease burden attribute to hepatitis B virus (HBV) infection. METHODS: Based on the mortality data of hepatitis B, liver cirrhosis and liver cancer derived from the third National Sampling Retrospective Survey for Causes of Death during 2004 and 2005, the incidence data of hepatitis B and the prevalence and the disability weights of liver cancer gained from the Shandong Cancer Prevalence Sampling Survey in 2007, we calculated the years of life lost (YLLs), years lived with disability (YLDs) and DALYs of three diseases following the procedures developed for the global burden of disease (GBD) study to ensure the comparability. RESULTS: The total burden for hepatitis B, liver cirrhosis and liver cancer were 211,616 (39,377 YLLs and 172,239 YLDs), 16,783 (13,497 YLLs and 3286 YLDs) and 247,795 (240,236 YLLs and 7559 YLDs) DALYs in 2005 respectively, and men were 2.19, 2.36 and 3.16 times as that for women, respectively in Shandong province. The burden for hepatitis B was mainly because of disability (81.39%). However, most burden on liver cirrhosis and liver cancer were due to premature death (80.42% and 96.95%). The burden of each patient related to hepatitis B, liver cirrhosis and liver cancer were 4.8, 13.73 and 11.11 respectively. CONCLUSION: Hepatitis B, liver cirrhosis and liver cancer caused considerable burden to the people living in Shandong province, indicating that the control of hepatitis B virus infection would bring huge potential benefits.

Liver transplantation outcomes among Caucasians, Asian Americans, and African Americans with hepatitis B.

Several previous studies found that Asians transplanted for hepatitis B virus (HBV) infection had worse post-transplant outcomes than Caucasians. Data on post-transplant outcomes of African Americans and waitlist outcomes of Asian Americans and African Americans with hepatitis B are scant. The aim of this study was to compare waitlist and post-transplant outcomes among Asian Americans, African Americans, and Caucasians who had HBV-related liver disease. Data from a retrospective-prospective study on liver transplantation for HBV infection were analyzed. A total of 274 patients (116 Caucasians, 135 Asians, and 23 African Americans) from 15 centers in the United States were enrolled. African Americans were younger and more Asian Americans had hepatocellular carcinoma (HCC) at the time of liver transplant listing. The probability of undergoing transplantation and the probability of survival on the waitlist were comparable in the 3 racial groups. Of the 170 patients transplanted, 19 died during a median follow-up of 31 months. The probability of post-transplant survival at 5 years was 94% for African Americans, 85% for Asian Americans, and 89% for Caucasians (P = 0.93). HCC recurrence was the only predictor of post-transplant survival, and recurrence rates were similar in the 3 racial groups. Caucasians had a higher rate of HBV recurrence: 4-year recurrence was 19% versus 7% and 6% for Asian Americans and African Americans, respectively (P = 0.043). In conclusion, we found similar waitlist and post-transplant outcomes among Caucasians, Asian Americans, and African Americans with hepatitis B. Our finding of a higher rate of HBV recurrence among Caucasians needs to be validated in other studies.
