RESUMEN
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 years (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 percentage 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.

Of 65 cases during a human immunodeficiency virus (HIV) outbreak among persons who inject drugs (PWID) in West Virginia (2019-2021), 61 (94%) had hepatitis C diagnosed a median of 46 months prior to HIV diagnosis. Hepatitis C diagnosis among PWID should trigger improved access to prevention and treatment services.

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 5773 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 nonhepatic malignancies among hepatitis B patients, as earlier diagnosis favors improved survival.

We compared rates of emergency department visits and hospitalizations between patients with hepatitis C virus who achieved sustained virological response after direct-acting antiviral therapy (case patients) and matched controls. Among 3049 pairs, case patients demonstrated lower rates of liver-related emergency department visits (Pâ =â .01) than controls; all-cause and liver-related hospitalization rates and number of hospitalized days were also lower in case patients (Pâ <â .001).

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.

Using electronic health records, we found that hepatitis C virus (HCV) reporting on death certificates of 2901 HCV-infected decedents from 4 US 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 US HCV mortality burden.

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.

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.

Improving care and treatment for persons infected with hepatitis C virus (HCV) can reduce HCV-related morbidity and mortality. Our primary objective was to examine the HCV care continuum among patients receiving care at five federally qualified health centers (FQHCs) in Philadelphia, PA, where a testing and linkage to care program had been established. Among the five FQHCs, one served a homeless population, two served public housing residents, one served a majority Hispanic population, and the last, a "test and treat" site, also provided HCV treatment to patients. We analyzed data from electronic health records of patients tested for HCV antibody from 2012 to 2016 and calculated the percentage of patients across nine steps of the HCV care continuum ranging from diagnosis to cure. We further explored factors associated with successful patient navigation through two steps of the continuum using multivariable logistic regression. Of 885 chronically infected patients, 92.2% received their RNA-positive result, 82.7% were referred to an HCV provider, 69.4% were medically evaluated by the provider, 55.3% underwent liver disease staging, 15.0% initiated treatment, 12.0% completed treatment, 8.7% were assessed for sustained virologic response (SVR), and 8.0% achieved SVR. Regression results revealed that test and treat site patients were significantly more likely to be medically evaluated (adjusted odds ratio [aOR], 2.76; 95% confidence interval [CI], 1.82-4.17) and to undergo liver disease staging (aOR, 1.92; 95% CI, 1.02-2.86) than patients at the other FQHCs combined. Conclusion: In this US urban setting, over two thirds of HCV-infected patients were linked to care; although treatment uptake was low overall, it was highest at the test and treat site; scaling up treatment services in HCV testing settings will be vital to improve the HCV care continuum.

There is increasing evidence that children and adolescents can efficiently transmit SARS-CoV-2, the virus that causes coronavirus disease 2019 (COVID-19) (1-3). During July-August 2020, four state health departments and CDC investigated a COVID-19 outbreak that occurred during a 3-week family gathering of five households in which an adolescent aged 13 years was the index and suspected primary patient; 11 subsequent cases occurred.

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.

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.

To reduce the risk of HIV, hepatitis B virus (HBV), and hepatitis C virus (HCV) transmission through organ transplantation, donors are universally screened for these infections by nucleic acid tests (NAT). Deceased organ donors are classified as "increased risk" if they engaged in specific behaviors during the 12 months before death. We developed a model to estimate the risk of undetected infection for HIV, HBV, and HCV among NAT-negative donors specific to the type and timing of donors' potential risk behavior to guide revisions to the 12-month timeline. Model parameters were estimated, including risk of disease acquisition for increased risk groups, number of virions that multiply to establish infection, virus doubling time, and limit of detection by NAT. Monte Carlo simulation was performed. The risk of undetected infection was <1/1 000 000 for HIV after 14 days, for HBV after 35 days, and for HCV after 7 days from the time of most recent potential exposure to the day of a negative NAT. The period during which reported donor risk behaviors result in an "increased risk" designation can be safely shortened.

The role of ribavirin (RBV) in the era of direct-acting antivirals (DAA) is not clear, and DAA studies have been largely genotype- and regimen-specific. Using data from the Chronic Hepatitis Cohort Study, we evaluated the role of RBV and increased DAA treatment duration among patients with chronic hepatitis C (HCV) in routine clinical care. We performed multivariable analysis of data from 4133 patients receiving any of the following: sofosbuvir (SOF); daclatasvir + SOF; grazoprevir + elbasvir; paritaprevir/ritonavir + ombitasvir; simeprevir + SOF; and SOF + ledipasvir; SOF + velpatasvir ± voxilaprevir; and glecaprevir + pibrentasvir-all with/ without RBV. Inverse probability treatment weighting was used to adjust for treatment selection bias. Sustained virological response (SVR) was defined by undetectable HCV RNA 12 weeks after end of therapy. The overall SVR rate was 95%. Mean treatment duration was 12 ± 4.5 weeks. The final model included treatment duration and diabetes, as well as the interaction of RBV with previous treatment status (treatment naïve, interferon treatment failure [TF] or previous DAA TF), cirrhosis status, and HCV genotype (GT). Each one-month increment of treatment duration increased odds of SVR by 99% (aOR = 1.99). Diabetes, previous DAA TF, and decompensated cirrhosis significantly reduced odds of SVR. RBV significantly increased the likelihood of SVR among patients with decompensated cirrhosis (aOR = 5.05), previous DAA treatment failure (aOR = 5.43), and GT3 (aOR = 13.28). Among RBV-free regimens, patients with GT3 were less likely to achieve SVR than those with GT1 or 2 (aOR 0.07). Diabetes, decompensated cirrhosis, and prior DAA TF independently reduced the likelihood of SVR. Longer treatment duration increased likelihood of SVR. Conclusion: RBV increased likelihood of SVR among patients with GT3, previous DAA TF, or decompensated cirrhosis.

BACKGROUND: Sustained virological response to treatment for chronic hepatitis C virus may improve short-term glucose control among patients with type 2 diabetes, but the long-term impact remains largely unknown. We used data from the Chronic Hepatitis Cohort Study to investigate the impact of sustained virological response on long-term trends in haemoglobin A1c in patients with type 2 diabetes. METHODS: "Index date" was defined as the date of treatment initiation (treated patients) or hepatitis C virus diagnosis (untreated patients). To address treatment selection bias, we used a propensity score approach. We used a piecewise, linear spline, mixed-effects model to evaluate changes in haemoglobin A1c over a 5-year period. RESULTS: Our sample included 384 hepatitis C virus patients with type 2 diabetes (192 untreated, 192 treated, with sustained virological response or treatment failure). After adjusting for body mass index, haemoglobin A1c was stable among untreated and treatment failure patients. In sustained virological response patients, Hb1Ac trajectories evolved in three phases: (a) index through 6 months post-index, average haemoglobin A1c decreased significantly from 7.7% to 5.4% per 90 days (P < 0.001); (b) 6-30 months post-index, haemoglobin A1c rebounded at a rate of 1.5% every 90 days (P = 0.003); and (c) from 30 months onward, haemoglobin A1c stabilized at an average level of 7.9 (P-value = 0.34). Results from an analysis restricted to patients receiving direct-acting antivirals were consistent with the main findings. CONCLUSION: Successful hepatitis C virus treatment among patients with type 2 diabetes significantly reduces HbA1c shortly after treatment, but these decreases are not sustained long-term. Less than three years after sustained virological response, haemoglobin A1c rebounds to levels similar to untreated/treatment failure patients, and higher than recommended for type 2 diabetic maintenance.

GOALS: To determine the impact of geography and patient characteristics on hepatitis C virus (HCV) genotype and subtype distribution in a large sample of patients under routine clinical care BACKGROUND:: HCV genotype impacts disease course and response to treatment. Although several studies have reported genotype distribution within specific US populations, there are no comprehensive descriptions in large, geographically diverse cohorts. STUDY: Using data from the Chronic Hepatitis Cohort Study, we present the distribution of HCV genotypes (GT) and subtypes (ST) among a racially diverse cohort of over 8000 HCV-infected patients from four large US health systems. RESULTS: Genotype distribution varied significantly by geographic and demographic factors. In age-adjusted analyses, African American patients had significantly higher prevalence of GT1 (85%) than other racial categories, largely driven by a markedly higher proportion of GT1 subtype b (â¼34%) than in Asian/other (24%) and white (21%) patients. GT3 represented an increasing proportion of infections as birth decade progressed, from 4% in patients born before 1946 to 18% of those born after 1976. Within the cohort of "living/uncured" patients, highly elevated alanine aminotransferase (>2 times the upper limit of normal) was significantly more common in GT3 patients, whereas Fibrosis-4 Index scores indicative of cirrhosis were most common in the combined group of GT4&6 patients. CONCLUSION: Distribution of HCV genotypes and subtypes in the United States is more variable than suggested by previous national-level estimates and single-center studies. "Real-world" prevalence data may improve targeting of prevention, screening, and treatment efforts for hepatitis C.

BACKGROUND & AIMS: Chronic hepatitis C virus (HCV)-related complications have increased over the past decade. METHODS: We used join-point regression modelling to investigate trends in these complications from 2006 to 2015, and the impact of demographics on these trends. Using data from the Chronic Hepatitis Cohort Study (CHeCS), we identified points at which the trend significantly changed, and estimated the annual percent change (APC) in rates of cirrhosis, decompensated cirrhosis and all-cause mortality, adjusted by race, sex and age. RESULTS: Among 11,167 adults with chronic HCV infection, prevalence of cirrhosis increased from 20.8% to 27.6% from 2006 to 2015, with adjusted annual percentage change (aAPC) of 1.2 (p <. 01). Although incidence of all-cause mortality increased from 1.8% in 2006 to 2.9% in 2015, a join-point was identified at 2010, with aAPCs of 9.6 before (2006 < 2010; p < .01) and -5.2 after (2010 ≤ 2015; p < .01), indicating a decrease in mortality from 2010 and onward. Likewise, overall prevalence of decompensated cirrhosis increased from 9.3% in 2006 to 10.4% in 2015, but this increase was confined to patients 60 or older (aAPC = 1.5; p = .023). Asian American and Black/African American patients demonstrated significantly higher rates of cirrhosis than White patients, while older patients and men demonstrated higher rates of cirrhosis and mortality. CONCLUSIONS: Although cirrhosis and mortality among HCV-infected patients in the US have increased over the past decade, all-cause mortality has decreased in recent years.

BACKGROUND: Limited information is available describing the uptake of direct-acting antiviral (DAA) therapy for hepatitis C virus (HCV) infection among patients in general US health care settings. We determined the proportion of HCV-infected patients in the Chronic Hepatitis Cohort Study prescribed DAAs in 2014, who initiated treatment and identified characteristics associated with treatment initiation. METHODS: Uptake was defined as the proportion of HCV-infected patients with at least 1 clinical encounter in 2013 who were prescribed a DAA regimen during 2014 and initiated the regimen by August 2015. Using multivariable analysis, we examined demographic and clinical characteristics associated with receipt of DAAs. RESULTS: The cohort comprised 9508 patients; 544 (5.7%) started a DAA regimen. Higher annual income [adjusted odds ratios (aOR) 2.3 for income>$50K vs. <$30K], higher Fibrosis-4 score (aORs, 2.1, 2.0, and 1.4 for Fibrosis-4, >5.88, 3.25 to 5.88, 2.0 to 3.25, respectively, vs. <2.0), genotype 2 infection (aOR 2.2 vs. genotype 1), pre-2014 treatment failure (aOR 2.0 vs. treatment-naive), and human immunodeficiency virus (HIV) coinfection (aOR 1.8 vs. HCV monoinfection) were associated with DAA initiation. Black race/ethnicity (aOR 0.7 vs. whites) and Medicaid coverage (aOR 0.5 vs. private insurance) were associated with noninitiation. Sex, age, comorbidity, previous liver transplant, and duration of follow-up were not associated with receipt of DAAs. CONCLUSIONS: Among patients in these general US health care settings, uptake of DAA therapy was low in 2014, and especially so among minority and Medicaid patients. Systemic efforts to improve access to DAAs for all patients are essential to reduce morbidity and mortality from HCV infection.

Although transmission of hepatitis A virus (HAV) through blood transfusion has been documented, transmission through organ transplantation has not been reported. In August 2015, state health officials in Texas, USA, were notified of 2 home health nurses with HAV infection whose only common exposure was a child who had undergone multi-visceral organ transplantation 9 months earlier. Specimens from the nurses, organ donor, and all organ recipients were tested and medical records reviewed to determine a possible infection source. Identical HAV RNA sequences were detected from the serum of both nurses and the organ donor, as well as from the multi-visceral organ recipient's serum and feces; this recipient's posttransplant liver and intestine biopsy specimens also had detectable virus. The other organ recipients tested negative for HAV RNA. Vaccination of the donor might have prevented infection in the recipient and subsequent transmission to the healthcare workers.
