Evolving characteristics of decedents with hepatitis A listed as a cause of death, United States, 2011-2021
Hofmeister MG , Ly KN , Yin S , Spradling PR . J Viral Hepat 2024 Hepatitis A is a vaccine-preventable disease that typically causes mild illness. Hepatitis A outbreaks associated with person-to-person transmission have been widespread in the United States since 2016. We used public-use US Multiple Cause of Death data to compare characteristics and listed comorbidities among decedents with hepatitis A-listed deaths during non-outbreak (2011-2015) and outbreak (2017-2021) periods and assessed the median age at death among decedents with and without hepatitis A-listed deaths during the outbreak period. From the non-outbreak period to the outbreak period, hepatitis A-listed deaths more than doubled (from 369 to 801), while the hepatitis A-listed age-adjusted mortality rate increased 150% (p < 0.001). When compared with the non-outbreak period, hepatitis A-listed decedents during the outbreak period were more frequently male, aged 18-49 years, non-Hispanic White, died in an inpatient setting, and had hepatitis A listed as their underlying cause of death. The median age at death for hepatitis A-listed decedents was significantly younger during the outbreak period overall and among females (62 and 66 years, respectively) compared with the non-outbreak period (64 and 72 years, respectively, p < 0.001). During the outbreak period, median age at death for hepatitis A-listed decedents was 14 years younger than decedents without hepatitis A listed. Compared with the general US population, decedents with hepatitis A listed on the death certificate died at younger ages during 2017-2021. Efforts are needed to improve hepatitis A vaccination coverage among adults recommended for hepatitis A vaccination to prevent additional premature hepatitis A deaths. |
Rate and durability of clearance of hepatitis B surface antigen in Alaska Native persons with long-term hepatitis B virus infection: 1982-2019
Bruden D , McMahon BJ , Snowball M , Towshend-Bulson L , Homan C , Johnston JM , Simons BC , Bruce MG , Cooley L , Spradling PR , Harris AM . Hepatology 2024 79 (6) 1412-1420 BACKGROUND AND AIMS: A functional cure and therapeutic end point of chronic HBV infection is defined as the clearance of HBsAg from serum. Little is known about the long-term durability of HBsAg loss in the Alaskan Native population. APPROACH AND RESULTS: We performed a retrospective cohort study of Alaska Native patients with chronic HBV-monoinfection from January 1982 through December 2019. The original group in this cohort was identified during a 1982 to 1987 population-based screening for 3 HBV serologic markers in 53,000 Alaska Native persons. With close to 32,000 years of follow-up, we assessed the frequency and duration of HBsAg seroclearance (HBsAg-negative for > 6 mo). We examined factors associated with HBsAg clearance and followed persons for a median of 13.1 years afterward to assess the durability of HBsAg clearance. Among 1079 persons with an average length of follow-up of 33 years, 260 (24%) cleared HBsAg at a constant rate of 0.82% per person/per year. Of the 260 persons who cleared, 249 (96%) remained HBsAg-negative, while 11 persons had ≥ 2 transient HBsAg-positive results in subsequent follow-up. CONCLUSIONS: Of the patients with chronic HBV monoinfection, 0.82% of people per year achieved a functional cure. HBsAg seroclearance was durable for treated and nontreated patients and lasted, on average, over 13 years without seroreversion. |
Regional differences in hepatitis C-related hospitalization rates, United States, 2012-2019
Hofmeister MG , Zhong Y , Moorman AC , Teshale EH , Samuel CR , Spradling PR . Public Health Rep 2024 333549241260252 OBJECTIVES: In the United States, hepatitis C is the most commonly reported bloodborne infection. It is a leading cause of liver cancer and death from liver disease and imposes a substantial burden of hospitalization. We sought to describe regional differences in hepatitis C virus (HCV)-related hospitalizations during 2012 through 2019 to guide planning for hepatitis C elimination. METHODS: We analyzed discharge data from the National Inpatient Sample for 2012 through 2019. We considered hospitalizations to be HCV-related if (1) hepatitis C was the primary diagnosis or (2) hepatitis C was any secondary diagnosis and the primary diagnosis was a liver disease-related condition. We analyzed demographic and clinical characteristics of HCV-related hospitalizations and modeled the annual percentage change in HCV-related hospitalization rates, nationally and according to the 9 US Census Bureau geographic divisions. RESULTS: During 2012-2019, an estimated 553 900 HCV-related hospitalizations occurred in the United States. The highest hospitalization rate (34.7 per 100 000 population) was in the West South Central region, while the lowest (17.6 per 100 000 population) was in the West North Central region. During 2012-2019, annual hospitalization rates decreased in each region, with decreases ranging from 15.3% in the East South Central region to 48.8% in the Pacific region. By type of health insurance, Medicaid had the highest hospitalization rate nationally and in all but 1 geographic region. CONCLUSIONS: HCV-related hospitalization rates decreased nationally and in each geographic region during 2012-2019; however, decreases were not uniform. Expanded access to direct-acting antiviral treatment in early-stage hepatitis C would reduce future hospitalizations related to advanced liver disease and interrupt HCV transmission. |
Disparities in social vulnerability and premature mortality among decedents with hepatitis B, United States, 2010-2019
Ly KN , Yin S , Spradling PR . J Racial Ethn Health Disparities 2024 BACKGROUND: Current US hepatitis B mortality rates remain three times higher than the national target. Mortality reduction will depend on addressing hepatitis B disparities influenced by social determinants of health. OBJECTIVES: This study aims to describe characteristics of hepatitis B-listed decedents, which included US birthplace status and county social vulnerability attributes and quantify premature mortality. METHODS: We conducted a cross-sectional analysis of 17,483 hepatitis B-listed decedents using the 2010-2019 US Multiple-Cause-of-Death data merged with the county-level Social Vulnerability Index (SVI). Outcomes included the distribution of decedents according to US birthplace status and residence in higher versus lower death burden counties by sociodemographic characteristics, years of potential life lost (YPLL), and SVI quartiles. RESULTS: Most hepatitis B-listed decedents were US-born, male, and born during 1945-1965. Median YPLL was 17.2; 90.0% died prematurely. US-born decedents were more frequently White, non-college graduates, unmarried, and had resided in a county with < 500,000 people; non-US-born decedents were more frequently Asian/Pacific Islander, college graduates, married, and had resided in a county with ≥ 1 million people. Higher death burden (≥ 20) counties were principally located in coastal states. US-born decedents more frequently resided in counties in the highest SVI quartile for "Household Characteristics" and "Uninsured," whereas non-US-born decedents more frequently resided in counties in the highest SVI quartile for "Racial/Ethnic Minority Status" and "Housing Type/Transportation." CONCLUSION: This analysis found substantial premature hepatitis B mortality and residence in counties ranked high in social vulnerability. Successful interventions should be tailored to disproportionately affected populations and the social vulnerability features of their geographic areas. |
Hepatitis B care continuum models-data to inform public health action
Spradling PR , Bocour A , Kuncio DE , Ly KN , Harris AM , Thompson ND . Public Health Rep 2024 333549231218277 The application of a care continuum model (CCM) can identify gaps in diagnosis, care, and treatment of populations with a common condition, but challenges are inherent in developing a CCM for chronic hepatitis B. In contrast with treatment for HIV or hepatitis C, treatment is not indicated for all people with chronic hepatitis B, clinical endpoints are not clear for those receiving treatment, and those for whom treatment is not indicated remain at risk for complications. This topical review examines the data elements necessary to develop and apply chronic hepatitis B CCMs at the jurisdictional health department level. We conducted a nonsystematic review of US-based publications in Ovid MEDLINE (1946-present), Ovid Embase (1974-present), and Scopus (not date limited) databases, which yielded 724 publications for review. Jurisdictional health departments, if properly supported, could develop locale-specific focused CCMs using person-level chronic hepatitis B registries, updated longitudinally using electronic laboratory reporting data and case reporting data. These CCMs could be applied to identify disparities and improve rates in testing and access to care and treatment, which are necessary to reduce liver disease and chronic hepatitis B mortality. Investments in public health surveillance infrastructure, including substantial enhancements in electronic laboratory reporting and case reporting and the use of supplementary data sources, could enable jurisdictional health departments to develop modified CCMs for chronic hepatitis B that focus, at least initially, on "early" CCM steps, which emphasize optimization of hepatitis B diagnosis, linkage to care, and ongoing clinical follow-up of diagnosed people, all of which can lead to improved outcomes. |
Use of hepatitis B vaccination for adults with diabetes mellitus: recommendations of the Advisory Committee on Immunization Practices (ACIP)
Centers for Disease Control and Prevention , Sawyer MH , Hoerger TJ , Murphy TV , Schillie SF , Hu D , Spradling PR , Byrd KK , Xing J , Reilly ML , Tohme RA , Moorman A , Smith EA , Baack BN , Jiles RB , Klevens M , Ward JW , Kahn HS , Zhou F . MMWR Morb Mortal Wkly Rep 2011 60 (50) 1709-11 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. |
Temporal trends in hepatitis C-related hospitalizations, United States, 2000-2019
Hofmeister MG , Zhong Y , Moorman AC , Samuel CR , Teshale EH , Spradling PR . Clin Infect Dis 2023 77 (12) 1668-1675 BACKGROUND: Hospitalization burden related to hepatitis C virus (HCV) infection is substantial. We sought to describe temporal trends in hospitalization rates before and after release of direct-acting antiviral (DAA) agents. METHODS: We analyzed 2000-2019 data from adults aged ≥18 years in the National Inpatient Sample. Hospitalizations were HCV-related if 1) hepatitis C was the primary diagnosis, or 2) hepatitis C was any secondary diagnosis with a liver-related primary diagnosis. We analyzed characteristics of HCV-related hospitalizations nationally, and examined trends in age-adjusted hospitalization rates. RESULTS: During 2000-2019, there were an estimated 1,286,397 HCV-related hospitalizations in the United States. The annual age-adjusted hospitalization rate was lowest in 2019 (18.7/100,000 population) and highest in 2012 (29.6/100,000 population). Most hospitalizations occurred among persons aged 45-64 (71.8%), males (67.1%), white non-Hispanic persons (60.5%), and Medicaid/Medicare recipients (64.0%). The national age-adjusted hospitalization rate increased during 2000-2003 (annual percent change [APC] 9.4%, P<.001) and 2003-2013 (APC 1.8%, P<.001) before decreasing during 2013-2019 (APC -7.6%, P<.001). Comparing 2000 to 2019, the largest increases in hospitalization rates occurred among persons aged 55-64 years (132.9%), Medicaid recipients (41.6%), and black non-Hispanic persons (22.3%). CONCLUSIONS: Although multiple factors likely contributed, overall HCV-related hospitalization rates declined steadily after 2013, coinciding with the release of DAAs. However, the declines were not observed equally among age, race/ethnicity, or insurance categories. Expanded access to DAA treatment is needed, particularly among Medicaid and Medicare recipients, to reduce disparities and morbidity, and eliminate hepatitis C as a public health threat. |
Progress and unfinished business: Hepatitis B in the United States, 1980-2019
Bixler D , Roberts H , Panagiotakopoulos L , Nelson NP , Spradling PR , Teshale EH . Public Health Rep 2023 333549231175548 During 1990-2019, universal infant and childhood vaccination for hepatitis B resulted in a 99% decline in reported cases of acute hepatitis B among children, adolescents, and young adults aged <19 years in the United States; however, during 2010-2019, cases of acute hepatitis B plateaued or increased among adults aged ≥40 years. We conducted a topical review of surveillance strategies that will be critical to support the elimination of hepatitis B as a public health threat in the United States. In 2019, notifiable disease surveillance for acute hepatitis B showed continued transmission, especially among people who inject drugs and people with multiple sexual partners; rates were highest among people who were aged 30-59 years, non-Hispanic White, and living in rural areas. In contrast, newly reported cases of chronic hepatitis B (CHB) were highest among people who were aged 30-49 years, Asian or Pacific Islander, and living in urban areas. The National Health and Nutrition Examination Survey documented the highest CHB prevalence among non-US-born, non-Hispanic Asian people during 2013-2018; only one-third of people with CHB were aware of their infection. In the context of universal adult vaccination (2022) and screening (2023) recommendations for hepatitis B, better data are needed to support programmatic strategies to improve (1) vaccination rates among people with behaviors that put them at risk for transmission and (2) screening and linkage to care among non-US-born people. Surveillance for hepatitis B needs to be strengthened throughout the health care and public health systems. |
Screening and testing for hepatitis B virus infection: CDC recommendations - United States, 2023
Conners EE , Panagiotakopoulos L , Hofmeister MG , Spradling PR , Hagan LM , Harris AM , Rogers-Brown JS , Wester C , Nelson NP . MMWR Recomm Rep 2023 72 (1) 1-25 Chronic hepatitis B virus (HBV) infection can lead to substantial morbidity and mortality. Although treatment is not considered curative, antiviral treatment, monitoring, and liver cancer surveillance can reduce morbidity and mortality. Effective vaccines to prevent hepatitis B are available. This report updates and expands CDC's previously published Recommendations for Identification and Public Health Management of Persons with Chronic Hepatitis B Virus Infection (MMWR Recomm Rep 2008;57[No. RR-8]) regarding screening for HBV infection in the United States. New recommendations include hepatitis B screening using three laboratory tests at least once during a lifetime for adults aged ≥18 years. The report also expands risk-based testing recommendations to include the following populations, activities, exposures, or conditions associated with increased risk for HBV infection: persons incarcerated or formerly incarcerated in a jail, prison, or other detention setting; persons with a history of sexually transmitted infections or multiple sex partners; and persons with a history of hepatitis C virus infection. In addition, to provide increased access to testing, anyone who requests HBV testing should receive it, regardless of disclosure of risk, because many persons might be reluctant to disclose stigmatizing risks. |
Prevalence and types of drugs used among hepatitis A patients during outbreaks associated with person-to-person transmission, Kentucky, Michigan, and West Virginia, 2016-2019
Hofmeister MG , Asher A , Jones CM , Augustine RJ , Burkholder C , Collins J , Foster MA , McBee S , Thoroughman D , Thomasson ED , Weng MK , Spradling PR . J Appalach Health 2022 4 (1) 51-60 BACKGROUND: People who use drugs are at increased risk for hepatitis A virus infection. Since 1996, the Advisory Committee on Immunization Practices has recommended hepatitis A vaccination for people who use drugs. Since 2016, the U.S. has experienced widespread hepatitis A outbreaks associated with person-to-person transmission. PURPOSE: To describe the prevalence of drug use, route of use, and drugs used among hepatitis A outbreak-associated patients. METHODS: State outbreak and medical records were reviewed to describe the prevalence, type, and route of drug use among a random sample of 812 adult outbreak-associated hepatitis A patients from Kentucky, Michigan, and West Virginia during 2016-2019. Differences in drug-use status were analyzed by demographic and risk-factor characteristics using the X (2) test. RESULTS: Among all patients, residents of Kentucky (55.6%), Michigan (51.1%), and West Virginia (60.1%) reported any drug use, respectively. Among patients that reported any drug use, methamphetamine was the most frequently reported drug used in Kentucky (42.3%) and West Virginia (42.1%); however, opioids were the most frequently reported drug used in Michigan (46.8%). Hepatitis A patients with documented drug use were more likely (p<0.05) to be experiencing homelessness/unstable housing, have been currently or recently incarcerated, and be aged 18-39 years compared to those patients without documented drug use. IMPLICATIONS: Drug use was prevalent among person-to-person hepatitis A outbreak-associated patients, and more likely among younger patients and patients experiencing homelessness or incarceration. Increased hepatitis A vaccination coverage is critical to prevent similar outbreaks in the future. |
Regional differences in mortality rates and characteristics of decedents with hepatitis B listed as a cause of death, United States, 2000-2019
Ly KN , Yin S , Spradling PR . JAMA Netw Open 2022 5 (6) e2219170 IMPORTANCE: US hepatitis B mortality has been described nationally, but examination subnationally may identify differences in mortality rates and decedent characteristics, including birthplace. OBJECTIVE: To examine characteristics of decedents with hepatitis B-listed deaths during 2010 to 2019 and compare age-adjusted hepatitis B-listed death rates during 2010 to 2019 vs 2000 to 2009. DESIGN, SETTING, AND PARTICIPANTS: This cross-sectional study used Multiple Cause of Death data from 50 US states and the District of Columbia (DC) from 2000 to 2019 to assess characteristics of US residents with hepatitis B listed as an underlying cause of death (UCOD) or contributing cause of death on death certificates. Data were analyzed from September 2019 to May 2022. EXPOSURES: Hepatitis B listed as underlying or contributing cause of death. MAIN OUTCOMES AND MEASURES: Outcomes of interest were hepatitis B-listed death counts, age-adjusted rates, and characteristics of decedents during 2000 to 2019. The distribution of hepatitis B-listed deaths according to sociodemographic characteristics and UCOD among US- and non-US-born decedents were also examined. RESULTS: A total of 35 280 decedents with hepatitis B listed as the cause of death were identified, including 17 483 deaths during 2010 to 2019. Decedents were 63.3% US-born, and 25.8% of decedents were Asian or Pacific Islander and 46.5% of decedents were White; 28.4% of decedents were listed as having hepatitis C virus (HCV) or HIV coinfection. State-level rates significantly surpassed the overall US rate (0.47 deaths per 100 000 population) in DC (high, 1.78 deaths per 100 000 population), Hawaii, Oklahoma, California, Tennessee, West Virginia, Mississippi, Oregon, Washington, Louisiana, Kentucky, and New York (low, 0.61 deaths per 100 000 population). Median (IQR) age at hepatitis B death was significantly younger in Kentucky (54.0 [46.0-64.0] years), West Virginia (56.0 [47.0-65.0] years), Tennessee (57.0 [50.0-65.0] years), Mississippi (58.0 [50.0-65.0] years), and Ohio (59.0 [50.0-66.0] years) than the national median (60.0 [53.0-69.0] years), which itself was significantly younger than nonhepatitis B-listed deaths (77 [63.0-87.0] years; P < .001). Hepatitis B was the UCOD among approximately 30% of US- and non-US-born decedents with hepatitis B COD. Irrespective of birthplace, most decedents had liver-related UCOD. Compared with non-US-born decedents, US-born decedents more frequently had nonliver conditions listed as UCOD. Liver cancer was the predominant UCOD among non-US-born decedents (37.9% of decedents). From 2000 to 2009 compared with 2010 to 2019, the hepatitis B-listed mortality rate significantly decreased nationally (change, -18.97%) and in 14 states; significant increases were observed in West Virginia (change, 83.78%) and Kentucky (change, 69.44%). CONCLUSIONS AND RELEVANCE: These findings suggest that US-born decedents constituted two-thirds of all hepatitis B-listed deaths and median age at death was youngest in Appalachian states. Irrespective of birthplace, most decedents had liver-related UCOD; however, US-born decedents more frequently had nonliver UCOD than non-US-born decedents. In addition to addressing liver-related complications, US-born persons with chronic infection may also require diagnosis and management of multiple comorbidities. |
Trends in cirrhosis and mortality by age, sex, race, and antiviral treatment status among US chronic hepatitis B patients (2006-2016)
Lu M , Li J , Zhou Y , Rupp LB , Moorman AC , Spradling PR , Teshale EH , Boscarino JA , Daida YG , Schmidt MA , Trudeau S , Gordon SC . J Clin Gastroenterol 2022 56 (3) 273-279 BACKGROUND: Changing US demographics and evolving chronic hepatitis B (CHB) treatments may affect longitudinal trends in CHB-related complications. We studied trends in the prevalence of cirrhosis (past or present) and incidence of all-cause mortality, stratified by patient age, sex, race, and antiviral treatment status, in a sample from US health care systems. METHODS: Joinpoint and Poisson regression (univariate and multivariable) were used to estimate the annual percent change in each outcome from 2006 to 2016. RESULTS: Among 5528 CHB patients, cirrhosis prevalence (including decompensated cirrhosis) rose from 6.7% in 2006 to 13.7% in 2016; overall mortality was unchanged. Overall rates of cirrhosis and mortality were higher among treated patients, but adjusted annual percent changes (aAPC) were significantly lower among treated than untreated patients (cirrhosis: aAPC +2.4% vs. +6.2%, mortality: aAPC -3.9% vs. +4.0%). Likewise, among treated patients, the aAPC for mortality declined -3.9% per year whereas among untreated patients, mortality increased +4.0% per year. CONCLUSIONS: From 2006 to 2016, the prevalence of cirrhosis among CHB patients doubled. Notably, all-cause mortality increased among untreated patients but decreased among treated patients. These results suggest that antiviral treatment attenuates the progression of cirrhosis and the risk of death among patients with CHB. |
Mortality among Alaska Native adults with confirmed hepatitis C virus infection compared with the general population in Alaska, 1995-2016
Bressler SS , Bruden D , Nolen LD , Bruce MG , Towshend-Bulson L , Spradling P , McMahon BJ . Can J Gastroenterol Hepatol 2022 2022 2573545 BACKGROUND: Hepatitis C virus (HCV) infection incidence rates in the United States have increased since 2010 as a byproduct of the opioid crisis despite the introduction of direct-acting antiviral agents in 2013. HCV infection is associated with higher rates of liver-related and nonhepatic causes of death. METHODS: This study compared demographic characteristics and age-adjusted death rates from 1995 to 2016 among Alaska Native (AN) adults infected with HCV (AK-HepC) to rates among the AN and non-AN adult populations living in Alaska. Liver-related disease (LRD) and other disease-specific age-adjusted death rates were compared between the populations. RESULTS: The all-cause death rate among the AK-HepC cohort was 2.2- and 3.4-fold higher than AN and non-AN adults, respectively, and remained stable over time in all populations. The LRD death rate among the AK-HepC cohort was 18- and 11-fold higher than the non-AN and AN, respectively. The liver cancer rate among the AK-HepC cohort was 26-fold higher compared to the Alaska statewide population. The AK-HepC cohort had elevated rates of death associated with nonhepatic diseases with circulatory disease having the highest rate in all populations. Among liver cancer deaths in the AK-HepC cohort, 32% had HCV listed as a contributing cause of death on the death certificate. CONCLUSIONS: Death rates in the AK-HepC cohort remained stable since 1995 and higher compared to the general population. People with HCV infection had an elevated risk for all-cause, liver-related, and nonhepatic causes of death. Hepatitis C infection may be underrepresented as a cause of mortality in the United States. |
Lower rates of emergency visits and hospitalizations among chronic hepatitis C patients with sustained virological response to interferon-free direct-acting antiviral therapy (2014-2018)
Gordon SC , Teshale EH , Spradling PR , Moorman AC , Boscarino JA , Schmidt MA , Daida YG , Rupp LB , Trudeau S , Zhang J , Lu M . Clin Infect Dis 2022 75 (8) 1453-1456 We compared rates of emergency department (ED) visits and hospitalizations between HCV patients who achieved sustained virological response (SVR) after direct-acting antiviral (DAA) therapy (cases) to matched controls. Among 3049 pairs, cases demonstrated lower rates of liver-related ED visits (P=.01) than controls; all-cause and liver-related hospitalization rates and hospitalized days were also lower in cases (P<.0001). |
Incidence of malignancies among patients with chronic hepatitis B in US health care organizations, 2006-2018

J Infect Dis 2022 226 (5) 896-900 Hepatitis B virus (HBV) infection causes hepatocellular carcinoma but its association with other cancers is not well established. We compared age-adjusted incidence of primary cancers among 5,773 HBV-infected persons with US cancer registries during 2006-2018. Compared with the US population, substantially higher incidence among HBV-infected persons was observed for hepatocellular carcinoma (Standardized rate ratio [SRR] 30.79), gastric (SRR 7.95), neuroendocrine (SRR 5.88), cholangiocarcinoma (SRR 4.62), and ovarian (SRR 3.72) cancers, and non-Hodgkin lymphoma (SRR 2.52). Clinicians should be aware of a heightened potential for certain non-hepatic malignancies among hepatitis B patients, as earlier diagnosis favors improved survival. |
Prevalence of indications for adult hepatitis A vaccination among hepatitis A outbreak-associated cases, three US states, 2016-2019
Hofmeister MG , Weng MK , Thoroughman D , Thomasson ED , McBee S , Foster MA , Collins J , Burkholder C , Augustine RJ , Spradling PR . Vaccine 2021 39 (44) 6460-6463 BACKGROUND: Safe and effective hepatitis A vaccines have been recommended in the United States for at-risk adults since 1996; however, adult vaccination coverage is low. METHODS: Among a random sample of adult outbreak-associated hepatitis A cases from three states that were heavily affected by person-to-person hepatitis A outbreaks, we assessed the presence of documented Advisory Committee on Immunization Practices (ACIP) indications for hepatitis A vaccination, hepatitis A vaccination status, and whether cases that were epidemiologically linked to an outbreak-associated hepatitis A case had received postexposure prophylaxis (PEP). RESULTS: Overall, 74.1% of cases had a documented ACIP indication for hepatitis A vaccination. Fewer than 20% of epidemiologically linked cases received PEP. CONCLUSIONS: Efforts are needed to increase provider awareness of and adherence to ACIP childhood and adult hepatitis A vaccination and PEP recommendations in order to stop the current person-to-person hepatitis A outbreaks and prevent similar outbreaks in the future. |
Hepatitis B Virus (HBV) Genotype: A Significant Risk Factor in Determining which Patients with Chronic HBV Infection should Undergo Surveillance for Hepatocellular Carcinoma: The Hepatitis B Alaska (HEP-B-AK) Study.
McMahon BJ , Nolen S , Snowball M , Homan C , Negus S , Roik E , Spradling PR , Bruden D . Hepatology 2021 74 (6) 2965-2973 BACKGROUND AND AIMS: Information is limited regarding hepatitis B virus (HBV) genotype and the outcome of chronic HBV (CHB) infection. We examined HBV genotype on hepatocellular carcinoma (HCC) occurrence in Alaska Native (AN) persons with CHB where five HBV genotypes are found, A2, B6, C2, D and F1. APPROACH AND RESULTS: We calculated HCC incidence per 1000 person-years of follow-up to determine which groups by age, sex, and genotype met current American Association for the Study of Liver Diseases HCC surveillance criteria. We used Poisson regression to compare HCC risk by genotype, age, sex, and Alaska region. Incidence of HCC was calculated using the sex specific AASLD cutoff recommended for the Asian population of 50 years for women and 40 years for men. HCC screening was conducted semiannually using alpha-fetoprotein levels and abdominal ultrasound. Among 1185 AN persons, median follow up was 35.1 years; 667 (63%) were male. The HBV genotype distribution was: 49% D, 18% F, 13% A, 6% C, 3% B, 0.1% H, and 12% undetermined. Sixty-three cases of HCC occurred. HCC incidence for genotype F was 5.73 per 1000 person-years of follow-up, followed by 4.77 for C, 1.28 for A, 0.47 for D and 0.00 for B. The HCC risk was higher for genotypes F (Relative rate [RR] : 12.7, 95% confidence interval [CI]: 6.1-26.4) , C (RR: 10.6, 95% CI: 4.3-26.0) and A (RR: 2.9, 95% CI: 1.0-8.0) compared to genotypes B or D. Among males < 40 years of age and females < 50 years of age, genotype F had the highest incidence (4.79/1000 person-years). CONCLUSIONS: HBV genotype was strongly associated with HCC HBV genotype should be considered in risk factor stratification. |
Estimated prevalence and number of persons with isolated antibody to hepatitis B core antigen and associated occult hepatitis B, United States, 2001-2018
Spradling PR , Xing J , Harris AM , Ly KN . J Infect Dis 2021 225 (3) 465-469 Persons with isolated antibody to HBV core antigen (IAHBc) may have occult HBV infection (OBI), which is associated with reactivation and potential risk for hepatocellular carcinoma and HBV transmission. We used National Health and Nutrition Examination Survey (NHANES) data to estimate US IAHBc prevalence and published studies of IAHBc-associated OBI prevalence to estimate OBI burden. During 2001-2018, IAHBc prevalence was 0.8% (approximately 2.1 million persons); OBI burden range was 35,500-83,600 persons. These data support the need for more robust estimates of IAHBc-associated OBI prevalence in the general US population. |
Trends in Prevalence and Characteristics of Resolved and Current Hepatitis B among US-Born Persons: National Health and Nutrition Examination Survey, 2001-2018
Ly KN , Xing J , Spradling PR . J Infect Dis 2021 224 (5) 804-812 BACKGROUND: After decades of decline, US incidence of acute hepatitis B flattened since 2010. In persons aged ≥40 years and in jurisdictions affected by the opioid epidemic, there is an increase in new cases. Data suggest new infections are occurring among US-born persons. METHODS: We used National Health and Nutrition Examination Survey data during 2001-2018 to examine trends and differences in total antibody to hepatitis B virus core antigen (anti-HBc) prevalence in US-born persons. During 2013-2018, the distribution of characteristics was examined. Cochran-Mantel-Haenszel test was used to assess trends. RESULTS: During 2001-2006, 2007-2012, and 2013-2018, anti-HBc prevalence was 3.5%, 2.5%, and 2.6% among US-born persons, respectively. This corresponded to 5.7 (range, 4.8-6.6) million US-born persons with resolved or current HBV infection during 2013-2018, including 347,100 persons aged 6-29 years. The most pronounced increase and highest anti-HBc prevalence was among persons who reported injection drug use (IDU), which increased from 35.3% during 2001-2006 to 58.4% during 2013-2018 (P=.07). CONCLUSIONS: Anti-HBc prevalence among US-born persons remained flat during the most recent period, coinciding with a doubling of prevalence among persons reporting IDU. These data are consistent with acute hepatitis B surveillance trends, showing increasing incidence in sub-populations where prevention could be strengthened. |
The persistence of underreporting of hepatitis C as an underlying or contributing cause of death, 2011-2017
Spradling PR , Zhong Y , Moorman AC , Rupp LB , Lu M , Teshale EH , Schmidt MA , Daida YG , Boscarino JA , Gordon SC . Clin Infect Dis 2021 73 (5) 891-894 Using electronic health records, we found that hepatitis C reporting on death certificates of 2,901 HCV-infected decedents from four U.S. healthcare organizations during 2011-2017 was documented in only 50% of decedents with hepatocellular carcinoma and less than half with decompensated cirrhosis. National figures likely underestimate the U.S. HCV mortality burden. |
Psychosocial obstacles to hepatitis C treatment initiation among patients in care: A hitch in the cascade of cure
Spradling PR , Zhong Y , Moorman AC , Rupp LB , Lu M , Gordon SC , Teshale EH , Schmidt MA , Daida YG , Boscarino JA . Hepatol Commun 2020 5 (3) 400-411 There are limited data examining the relationship between psychosocial factors and receipt of direct-acting antiviral (DAA) treatment among patients with hepatitis C in large health care organizations in the United States. We therefore sought to determine whether such factors were associated with DAA initiation. We analyzed data from an extensive psychological, behavioral, and social survey (that incorporated several health-related quality of life assessments) coupled with clinical data from electronic health records of patients with hepatitis C enrolled at four health care organizations during 2017-2018. Of 2,681 patients invited, 1,051 (39.2%) responded to the survey; of 894 respondents eligible for analysis, 690 (77.2%) initiated DAAs. Mean follow-up among respondents was 9.2 years. Compared with DAA recipients, nonrecipients had significantly poorer standardized scores for depression, anxiety, and life-related stressors as well as poorer scores related to physical and mental function. Lower odds of DAA initiation in multivariable analysis (adjusted by age, race, sex, study site, payment provider, cirrhosis status, comorbidity status, and duration of follow-up) included Black race (adjusted odds ratio [aOR], 0.59 vs. White race), perceived difficulty getting medical care in the preceding year (aOR, 0.48 vs. no difficulty), recent injection drug use (aOR, 0.11 vs. none), alcohol use disorder (aOR, 0.58 vs. no alcohol use disorder), severe depression (aOR, 0.42 vs. no depression), recent homelessness (aOR, 0.36 vs. no homelessness), and recent incarceration (aOR, 0.34 vs. no incarceration). Conclusion(s): In addition to racial differences, compared with respondents who initiated DAAs, those who did not were more likely to have several psychological, behavioral, and social impairments. Psychosocial barriers to DAA initiation among patients in care should also be addressed to reduce hepatitis C-related morbidity and mortality. |
Factors associated with hepatitis A mortality during person-to-person outbreaks: A matched case-control study-United States, 2016-2019
Hofmeister MG , Xing J , Foster MA , Augustine RJ , Burkholder C , Collins J , McBee S , Thomasson ED , Thoroughman D , Weng MK , Spradling PR . Hepatology 2020 74 (1) 28-40 BACKGROUND & AIMS: During 2016-2020, the United States experienced person-to-person hepatitis A outbreaks that are unprecedented in the vaccine era, during which case-fatality ratios reported by some jurisdictions exceeded those historically associated with hepatitis A. APPROACH & RESULTS: To identify factors associated with hepatitis A-related mortality, we performed a matched case-control study (matched on age [±5 years] and county of residence in a 1:4 ratio) using data collected from health department and hospital medical records of outbreak-associated patients in Kentucky, Michigan, and West Virginia. Controls were hepatitis A outbreak-associated patients who did not die. There were 110 cases (mean age 53.6 years) and 414 matched controls (mean age 51.9 years); most cases (68.2%) and controls (63.8%) were male. Significantly (p<0.05) higher odds of mortality were associated with pre-existing non-viral liver disease (adjusted odds ratio [aOR] 5.2), history of hepatitis B (aOR 2.4), diabetes (aOR 2.2), and cardiovascular disease (aOR 2.2), as well as initial MELD score ≥30 (aOR 10.0), AST/ALT ratio >2 (aOR 10.3), and platelet count <150,000/uL (aOR 3.7) among hepatitis A outbreak-associated patients in the independent multivariable conditional logistic regression analyses (each model adjusted for sex). CONCLUSIONS: Pre-existing liver disease, diabetes, cardiovascular disease, and initial MELD score ≥30, AST/ALT ratio ≥1, or platelet count <150,000/uL among hepatitis A patients were independently associated with higher odds of mortality. Providers should be vigilant for such features and have a low threshold to escalate care and consider consultation for liver transplantation. Our findings support the Advisory Committee on Immunization Practices recommendation to vaccinate persons with chronic liver disease, though future recommendations to include adults with diabetes and cardiovascular disease should be considered. |
Hepatitis A person-to-person outbreaks: Epidemiology, morbidity burden, and factors associated with hospitalization - multiple states, 2016-2019
Hofmeister MG , Xing J , Foster MA , Augustine RJ , Burkholder C , Collins J , McBee S , Thomasson ED , Thoroughman D , Weng MK , Spradling PR . J Infect Dis 2020 223 (3) 426-434 BACKGROUND: Since 2016, the US has experienced person-to-person hepatitis A outbreaks unprecedented in the vaccine era. The proportion of cases hospitalized in these outbreaks exceeds historical national surveillance data. METHODS: We described the epidemiology, characterized the reported increased morbidity, and identified factors associated with hospitalization during the outbreaks by reviewing a 10% random sample of outbreak-associated hepatitis A cases in Kentucky, Michigan, and West Virginia-three heavily affected states. We calculated descriptive statistics and conducted age-adjusted log-binomial regression analyses to identify factors associated with hospitalization. RESULTS: Participants in the random sample (n=817) were primarily male (62.5%) with mean age of 39.0 years; 51.8% were hospitalized. Among those with available information, 73.2% reported drug use, 14.0% were experiencing homelessness, 29.7% were currently or recently incarcerated, and 61.6% were epidemiologically linked to a known outbreak-associated case. Residence in Michigan (adjusted risk ratio [aRR] 1.8), being a man who has sex with men (aRR 1.5), non-injection drug use (aRR 1.3), and homelessness (aRR 1.3) were significantly (p<0.05) associated with hepatitis A-related hospitalization. CONCLUSIONS: Our findings support current Advisory Committee on Immunization Practices recommendations to vaccinate all persons who use drugs, men who have sex with men, and persons experiencing homelessness against hepatitis A. |
Testing and clinical management of health care personnel potentially exposed to hepatitis C virus - CDC Guidance, United States, 2020
Moorman AC , de Perio MA , Goldschmidt R , Chu C , Kuhar D , Henderson DK , Naggie S , Kamili S , Spradling PR , Gordon SC , Russi MB , Teshale EH . MMWR Recomm Rep 2020 69 (6) 1-8 Exposure to hepatitis viruses is a recognized occupational risk for health care personnel (HCP). This report establishes new CDC guidance that includes recommendations for a testing algorithm and clinical management for HCP with potential occupational exposure to hepatitis C virus (HCV). Baseline testing of the source patient and HCP should be performed as soon as possible (preferably within 48 hours) after the exposure. A source patient refers to any person receiving health care services whose blood or other potentially infectious material is the source of the HCP's exposure. Two options are recommended for testing the source patient. The first option is to test the source patient with a nucleic acid test (NAT) for HCV RNA. This option is preferred, particularly if the source patient is known or suspected to have recent behaviors that increase risk for HCV acquisition (e.g., injection drug use within the previous 4 months) or if risk cannot be reliably assessed. The second option is to test the source patient for antibodies to hepatitis C virus (anti-HCV), then if positive, test for HCV RNA. For HCP, baseline testing for anti-HCV with reflex to a NAT for HCV RNA if positive should be conducted as soon as possible (preferably within 48 hours) after the exposure and may be simultaneous with source-patient testing. If follow-up testing is recommended based on the source patient's status (e.g., HCV RNA positive or anti-HCV positive with unavailable HCV RNA or if the HCV infection status is unknown), HCP should be tested with a NAT for HCV RNA at 3-6 weeks postexposure. If HCV RNA is negative at 3-6 weeks postexposure, a final test for anti-HCV at 4-6 months postexposure is recommended. A source patient or HCP found to be positive for HCV RNA should be referred to care. Postexposure prophylaxis of hepatitis C is not recommended for HCP who have occupational exposure to blood and other body fluids. This guidance was developed based on expert opinion (CDC. Updated U.S. Public Health Service guidelines for the management of occupational exposures to HBV, HCV, and HIV and recommendations for postexposure prophylaxis. MMWR Recommend Rep 2001;50[No. RR-11]; Supplementary Figure, https://stacks.cdc.gov/view/cdc/90288) and reflects updated guidance from professional organizations that recommend treatment for acute HCV infection. Health care providers can use this guidance to update their procedures for postexposure testing and clinical management of HCP potentially exposed to hepatitis C virus. |
Immunogenicity of the hepatitis A vaccine 20 years after infant immunization
Mosites E , Seeman S , Negus S , Homan C , Morris J , Nelson NP , Spradling PR , Bruce M , McMahon B . Vaccine 2020 38 (32) 4940-4943 To determine the duration of immunity provided by the Hepatitis A vaccination (HepA), we evaluated a cohort of participants in Alaska 20 years after being immunized as infants. At recruitment, participants received two doses of inactivated HepA vaccine on one of three schedules. We conducted hepatitis A antibody (anti-HAV) testing for participants at the 20-year time-point. Seventy-five of the original 183 participants (41%) were available for follow-up. The overall anti-HAV geometric mean concentration was 29.9 mIU/mL (95% CI 22.4 mIU/mL, 39.7 mIU/mL) and 50 participants (68%) remained seropositive (titer >/= 20 mIU/mL). Using a fractional polynomial model, the predicted percent seropositive at 25 years was 55.3%, 49.8% at 30 years and 45.7% at 35 years, suggesting that the percent sero-positive could drop below 50% earlier than previously expected. Further research is necessary to understand if protection continues after seropositivity diminishes or if a HepA booster dose may become necessary. |
Hepatitis A hospitalization costs, United States, 2017
Hofmeister MG , Yin S , Aslam MV , Teshale EH , Spradling PR . Emerg Infect Dis 2020 26 (5) 1040-1041 The United States is in the midst of unprecedented person-to-person hepatitis A outbreaks. By using Healthcare Cost and Utilization Project data, we estimated the average costs per hepatitis A-related hospitalization in 2017. These estimates can guide investment in outbreak prevention efforts to stop the spread of this vaccine-preventable disease. |
Mortality among patients with chronic hepatitis B infection: The Chronic Hepatitis Cohort Study (CHeCS)
Bixler D , Zhong Y , Ly KN , Moorman AC , Spradling PR , Teshale EH , Rupp LB , Gordon SC , Boscarino JA , Schmidt MA , Daida YG , Holmberg SD . Clin Infect Dis 2019 68 (6) 956-963 BACKGROUND: According to death certificates, approximately 1800 persons die from hepatitis B annually in the United States; however, this figure may underestimate true mortality from chronic hepatitis B (CHB). METHODS: We analyzed data from CHB patients seen in the Chronic Hepatitis Cohort Study (CHeCS) between 1 January 2006 and 31 December 2013. We compared overall and cause-specific death rates and mean ages at death between CHeCS CHB decedents and U.S. decedents from the Multiple Cause of Death (MCOD) file. RESULTS: Of 4389 CHB patients followed for a mean of 5.38 years, 492 (11%) CHB patients died after a mean follow-up of 3.00 years. Compared to survivors, decedents were older, more likely to be White (40.6%), African-American (27.1%), or male (74.2%); and more likely to have had cirrhosis (59.8%), diabetes (27.2%), alcohol abuse (17.7%), hepatocellular carcinoma (17.5%), or a liver transplant (5.7%); whereas survivors were more likely to be Asian (48.8%; all P < .001). CHB patients died at an average age of 59.8 years-14 years younger than the general U.S. population-and at higher rates for all causes (relative risk [RR] = 1.85, 95% confidence interval [CI], 1.851-1.857) and liver-related causes (RR = 15.91, 95% CI, 15.81-16.01). Only 19% of CHB decedents and 40% of those dying of liver disease had hepatitis B reported on their death certificates. CONCLUSIONS: Compared to the general population, CHB patients die at younger ages and higher rates from all causes and liver-related causes. Death certificates underrepresent the true mortality from CHB. |
Low uptake of direct-acting antiviral therapy among hepatitis C patients with advanced liver disease and access to care, 2014-2017
Spradling PR , Xing J , Rupp LB , Moorman AC , Gordon SC , Lu M , Teshale EH , Boscarino JA , Schmidt MA , Daida YG , Holmberg SD . J Clin Gastroenterol 2020 55 (1) 77-83 GOALS: To determine the proportion and characteristics of adults with hepatitis C at health care organizations in 4 US states who initiated direct-acting antivirals (DAAs). BACKGROUND: There are almost no data to assess the penetrance of treatment of the hepatitis C population in general US health care settings. STUDY: We conducted a prospective observational study using electronic clinical, pharmacy, and mortality data to determine the fraction of patients who initiated DAAs between January 2014 and December 2017, by start date and regimen. We used stepwise multivariate logistic regression analysis to identify sociodemographic and clinical characteristics associated with receipt of DAAs. RESULTS: Of 8823 patients, 2887 (32.7%) received DAAs. Quarterly (Q) uptake ranged from 1.1% in Q3 2014 to a high of 5.6% in Q2 2015. Characteristics associated with receipt of DAAs included age 51 to 70 years, higher income, pre-2014 treatment failure, and higher noninvasive fibrosis score (FIB4); however, over one half of patients with FIB4 scores >3.25, consistent with severe liver disease, were not treated. A lower likelihood of initiation was associated with Medicaid coverage. Of 5936 patients who did not initiate treatment, 911 (15.3%) had died and 2774 (46.7%) had not had a clinical encounter in >/=12 months by the end of the study. Fewer than 1% of DAA prescriptions originated from nonspecialty providers. CONCLUSIONS: During 4 calendar years of follow-up, one third of patients initiated DAAs. Large fractions of untreated patients had advanced liver disease, died, or were lost to follow-up. Even among patients in integrated health care systems, receipt of DAAs was limited. |

Daida YG , Boscarino JA , Moorman AC , Lu M , Rupp LB , Gordon SC , Teshale EH , Schmidt MA , Spradling PR . Qual Life Res 2020 29 (6) 1567-1577 PURPOSE: Little is known about health-related quality of life (HRQoL) in patients with chronic hepatitis B virus (CHB) infection in the United States. Our goal is to understand factors associated with HRQoL in this population. METHODS: We conducted a survey to assess HRQoL and behavioral risks among patients with CHB infection from four large U.S. health care systems. Primary outcomes were generated from the SF-8 scale to assess HRQoL, as measured by the mental component scores (MCS) and physical component scores (PCS). The survey also measured socio-demographic information, hepatitis-related behavioral risk factors, treatment exposure/history, stress, and social support. We supplemented survey data with electronic health records data on patient income, insurance, disease severity, and comorbidities. Multivariate analysis was used to estimate and compare adjusted least square means of MCS and PCS, and examine which risk factors were associated with lower MCS and PCS. RESULTS: Nine hundred sixty-nine patients (44.6%) responded to the survey. Current life stressors and unemployment were associated with both lower MCS and PCS results in multivariate analyses. Lower MCS was also associated with White race and low social support, while lower PCS was also associated with Medicaid insurance. CONCLUSIONS: Stressful life events and unemployment were related to mental and physical health status of CHB patients. Those who have social support have better mental health; White and Medicaid patients are more likely to have poorer mental and physical health, respectively. Management of CHB patients should include stress management, social support, and financial or employment assistance. |
