BACKGROUND: Hepatitis C virus (HCV) infection has been increasing among people who inject drugs (PWID), younger than 30 years, and living in rural or suburban areas. We examined injection-related behaviors of young PWID to determine factors associated with HCV infection. METHODS: From September 2013-May 2015, respondent-driven and snowball sampling were used in 3 suburban areas of Wisconsin to recruit PWID 18-29 years who reported injection drug use in the previous 12 months. Participants were tested for HCV antibody (anti-HCV) and reported injection-related behaviors/practices via self-administered computer-based survey. We calculated anti-HCV prevalence and assessed associated factors using multivariable logistic regression. RESULTS: Forty-two percent (117/280) of participants were male, 83% (231/280) were white, and median age was 23 years. Overall HCV prevalence was 33%, but HCV prevalence among males was 39%. Adjusting for age, sex, race/ethnicity, education, relationship status, insurance status and income, anti-HCV positivity was associated with higher injection frequency (> 100 times in the past six months) (aOR = 3.07; 95% Confidence Interval (95% CI): 1.72-5.45), ever shared syringes (aOR = 5.15; 95% CI: 2.52-10.51), past week/last use receptive rinse water sharing (aOR = 1.88; 95% CI: 1.06-3.33), past week/last use receptive filter sharing (aOR = 3.25; 95% CI: 1.61-6.54), reusing syringes (aOR = 1.91, 95% CI: 1.08-3.37), history of overdose (aOR = 8.82; 95% CI: 2.26-3.95), and having ever injected another PWID (aOR = 8.82; 95%CI 3.94-19.76). DISCUSSION: Anti-HCV positivity is associated with high-risk injection practices. Young PWID would benefit from access to evidence-based interventions that reduce their risk of infection, link those infected to HCV treatment, and provide education to reduce further transmission.

BACKGROUND: Hepatitis C infection could be eliminated. Underdiagnosis and lack of treatment are the barriers to cure, especially for vulnerable populations (i.e. unable to pay for health care). METHODS: A multilevel intervention from September 2014 to September 2019 focused on the providers and organizations in 'the safety net' (providing health care to populations unable to pay), including: (i) public education, (ii) training for primary care providers (PCPs) and case managers, (iii) case management for high-risk populations, (iv) policy advice and (v) a registry (Registry) for 13 health centers contributing data. The project tracked the number of PCPs trained and, among Registry sites, the number of people screened, engaged in care (i.e. clinical follow-up after diagnosis), treated and/or cured. RESULTS: In Chicago, 215 prescribing PCPs and 56 other health professionals, 86% of whom work in the safety net, were trained to manage hepatitis C. Among Registry sites, there was a 137% increase in antibody screening and a 32% increase in current hepatitis C diagnoses. Engagement in care rose by 18%. CONCLUSIONS: Hepatitis C Community Alliance to Test and Treat (HepCCATT) successfully targeted safety net providers and organizations with a comprehensive care approach. While there were challenges, HepCCATT observed increased hepatitis C screening, diagnosis and engagement in care in the Chicago community.

Hepatitis C virus (HCV) infection is common in the United States and leads to significant morbidity, mortality, and economic costs. Simplified screening recommendations and highly effective direct-acting antivirals for HCV present an opportunity to eliminate HCV. The objective of this study was to increase testing, linkage to care, treatment, and cure of HCV. This was an observational, prospective, population-based intervention program carried out between September 2014 and September 2018 and performed in three community health centers, three large multiclinic health care systems, and an HCV patient education and advocacy group in King County, WA. There were 232,214 patients included based on criteria of documented HCV-related diagnosis code, positive HCV laboratory test or prescription of HCV medication, and seen at least once at a participating clinical site in the prior year. Electronic health record (EHR) prompts and reports were created. Case management linked patients to care. Primary care providers received training through classroom didactics, an online curriculum, specialty clinic shadowing, and a telemedicine program. The proportion of baby boomer patients with documentation of HCV testing increased from 18% to 54% during the project period. Of 77,577 baby boomer patients screened at 87 partner clinics, 2,401 (3%) were newly identified HCV antibody positive. The number of patients staged for treatment increased by 391%, and those treated increased by 1,263%. Among the 79% of patients tested after treatment, 95% achieved sustained virologic response. Conclusion(s): A combination of EHR-based health care system interventions, active linkage to care, and clinician training contributed to a tripling in the number of patients screened and a more than 10-fold increase of those treated. The interventions are scalable and foundational to the goal of HCV elimination.

In 2014, trained health care provider capacity was insufficient to deliver care to an estimated 70,000 persons in Maryland with chronic hepatitis C virus (HCV) infection. The goal of Maryland Community Based Programs to Test and Cure Hepatitis C, a public health implementation project, was to improve HCV treatment access by expanding the workforce. Sharing the Cure (STC) was a package of services deployed 10/1/14 to 9/30/18 that included enhanced information technology and public health infrastructure, primary care provider training, and practice transformation. Nine primary care sites enrolled. HCV clinical outcomes were documented among individuals who presented for care at sites and met criteria for HCV testing including risk factor or birth cohort (born between 1945 and 1965) based testing. Fifty-three providers completed the STC training. STC providers identified 3,237 HCV antibody positive patients of which 2,624 (81%) were RNA+. Of those HCV RNA+, 1,739 (66%) were staged, 932 (36%) were prescribed treatment, 838 (32%) started treatment, 721 (28%) completed treatment, and 543 (21%) achieved cure. Among 1,739 patients staged, 693 (40%) patients had a liver fibrosis assessment score < F2, rendering them ineligible for treatment under Maryland Medicaid guidelines. HCV RNA testing among HCV antibody positive people increased from 40% (baseline) to 95% amongst STC providers. Of 554 patients with virologic data reported, 543 (98%) achieved cure. Primary care practices can effectively serve as HCV treatment centers to expand treatment access. However, criteria by insurance providers in Maryland was a major barrier to treatment.

INTRODUCTION: Perinatal transmission is an increasingly important mode of hepatitis C virus transmission. The authors characterized U.S. births among hepatitis C virus-infected women and evaluated trends in hepatitis C virus testing and positivity in women of childbearing age, pregnant women, and children aged less than 5years. METHODS: In 2017, National Center for Health Statistics birth certificate data (48 states and District of Columbia) were analyzed to assess the number of hepatitis C virus-infected women delivering live births in 2015, and commercial laboratory data were analyzed to assess hepatitis C virus testing and positivity among women of childbearing age, pregnant women, and children aged <5years from 2011 to 2016. RESULTS: In 2015, a total of 0.38% (n=14,417) of live births were delivered by hepatitis C virus-infected women. Births delivered by hepatitis C virus-infected women, compared with births overall, occurred more often in women who were aged 20-29years (60.7% vs 50.9%); white, non-Hispanic (80.2% vs 52.8%); covered by Medicaid or other government insurance (79.2% vs 43.9%); and had rural residence (26.0% vs 14.0%). From 2011 to 2016 laboratory data, among women of childbearing age, hepatitis C virus testing increased by 39%, from 6.1% to 8.4%, and positivity increased by 36%, from 4.4% to 6.0%. Among pregnant women, hepatitis C virus testing increased by 135%, from 5.7% to 13.4%, and positivity increased by 39%, from 2.6% to 3.6%. Among children, hepatitis C virus testing increased by 25%, from 0.47% to 0.59%, and positivity increased by 13%, from 3.6% to 4.0%. CONCLUSIONS: The potential for perinatal hepatitis C virus transmission exists. Expanded hepatitis C virus testing guidelines may address the burden of disease in this population.

Hepatitis C is associated with more deaths in the United States than 60 other infectious diseases reported to CDC combined. Despite curative hepatitis C virus (HCV) therapies and known preventive measures to interrupt transmission, new HCV infections have increased in recent years. Injection drug use is the primary risk factor for new HCV infections. One potential strategy to decrease the prevalence of HCV is to create and strengthen public health laws and policies aimed specifically at reducing transmission risks among persons who inject drugs. To evaluate factors affecting access to HCV preventive and treatment services, CDC assessed state laws governing access to safe injection equipment and Medicaid policies related to sobriety requirements for approval of HCV treatment for persons who inject drugs. Acute HCV incidence rates were obtained from CDC's National Notifiable Disease Surveillance System (NNDSS). States were categorized based on analysis of laws related to access to clean needles and syringes and Medicaid HCV treatment policies associated with sobriety requirements. In 2015, HCV incidence remained high in the United States, with rates in 17 states exceeding the national average. Three states were determined to have state laws and Medicaid policies capable of comprehensively preventing and treating HCV among persons who inject drugs. Opportunities exist for states to adopt laws and policies that could help increase access to HCV preventive and treatment services reducing the number of persons at risk for HCV transmission and disease.

Using commercial laboratory data, we found 80% of 29,382 young people currently infected with hepatitis C lived >10 miles from a syringe services program. The median distance was 37 miles, with greater distances in rural areas and Southern and Midwestern states. Strategies to improve access to preventive services are warranted.

Since the introduction of antimicrobials in the first half of the twentieth century, Neisseria gonorrhoeae has repeatedly acquired resistance to the drugs used for treatment. The victims of the bacterium’s relentless acquisition of resistance have included sulfonamides, penicillin, tetracycline, and fluoroquinolones. During the past several years, gonococcal resistance has received substantial attention in the United States. Circulating strains of N. gonorrhoeae have been found to have reduced susceptibility to recommended treatment options, the antibiotic pipeline remains at a trickle, and STD public health programs are stretched increasingly thin as syphilis, chlamydia, and gonorrhea case rates are increasing.[1] Taking its place among the ranks of Clostridium difficile and carbapenem-resistant Enterobacteriaceae, N. gonorrhoeae was labeled an “urgent” antibiotic resistance threat by the Centers for Disease Control and Prevention in 2013.[2] | N. gonorrhoeae antimicrobial resistance is a reminder of our global interconnectedness. Penicillinase-producing N. gonorrhoeae, fluoroquinolone-resistant N. gonorrhoeae, and strains with reduced cephalosporin susceptibility seem to have initially emerged or at least been initially detected in East Asia before being detected in other countries around the world in subsequent years, including the United States.[3–5] In some ways, gonococcal resistance trends and developments in East Asia have served as a canary in a coal mine, allowing us to anticipate possible future developments elsewhere. Thus antimicrobial susceptibility surveillance data from Japan, such as presented in this issue by Yasuda et al, are welcome contributions to our understanding of gonococcal resistance worldwide.[6]

BACKGROUND: Knowledge of the estimated proportion of hepatitis C virus (HCV)-infected persons with advanced fibrosis or cirrhosis is critical to estimating healthcare needs. METHODS: We analyzed HCV-related testing conducted by Quest Diagnostics from January 2010 through December 2013. Tests included hepatitis C antibody, HCV RNA, HCV genotype (nucleic acid tests [NAT]), liver function tests, and platelet counts; patient age was also determined. Aspartate aminotransferase (AST)-to-platelet ratio (APRI) was calculated as = 100*(aspartate aminotransferase [AST]/upper limit of AST)/platelet. Fibrosis-4 (FIB-4) was calculated as (age x AST)/(platelet x radical alanine aminotransferase [ALT]). Persons were "currently infected" if they had ≥1 positive HCV NAT; "in care" if a positive RNA test was followed <6 months by ≥1 additional NAT(s), or ALT, AST, and platelets <90 days, or any test ordered by an infectious diseases or gastroenterology specialist; and "evaluated for treatment" if they had a genotype test. RESULTS: Approximately 10 million HCV test results were analyzed, representing 5.6 million unique patients. Of the 2.6 million patients with data to estimate liver disease, 5% were currently infected. Among those currently infected, APRI and FIB-4 scores indicated that 23% overall-and 27% among the cohort born during 1945-1965-had advanced fibrosis or cirrhosis at first diagnosis. A total of 54% of infected were in care and 51% of infected with advanced fibrosis or cirrhosis were evaluated for treatment. CONCLUSIONS: Testing from a large US commercial laboratory indicates that about 1 in 4 HCV-infected persons have levels of liver disease put them at highest risk for complications and could benefit from immediate antiviral therapy.

Hepatitis C virus (HCV) infection is a leading cause of liver-related morbidity and mortality (1). Transmission of HCV is primarily via parenteral blood exposure, and HCV can be transmitted vertically from mother to child. Vertical transmission occurs in 5.8% (95% confidence interval = 4.2%-7.8%) of infants born to women who are infected only with HCV and in up to twice as many infants born to women who are also infected with human immunodeficiency virus (HIV) (2) or who have high HCV viral loads (3,4); there is currently no recommended intervention to prevent transmission of infection from mother to child (3). Increased reported incidence of HCV infection among persons aged ≤30 years (5,6) with similar increases among women and men in this age group (6), raises concern about increases in the number of pregnant women with HCV infection, and in the number of infants who could be exposed to HCV at birth. Data from one large commercial laboratory and birth certificate data were used to investigate trends in HCV detection among women of childbearing age,* HCV testing among children aged ≤2 years, and the proportions of infants born to HCV-infected women nationally and in Kentucky, the state with the highest incidence of acute HCV infection during 2011-2014 (6). During 2011-2014, commercial laboratory data indicated that national rates of HCV detection (antibody or RNA positivitydagger) among women of childbearing age increased 22%, and HCV testing (antibody or RNA) among children aged ≤2 years increased 14%; birth certificate data indicated that the proportion of infants born to HCV-infected mothers increased 68%, from 0.19% to 0.32%. During the same time in Kentucky, the HCV detection rate among women of childbearing age increased >200%, HCV testing among children aged ≤2 years increased 151%, and the proportion of infants born to HCV-infected women increased 124%, from 0.71% to 1.59%. Increases in the rate of HCV detection among women of childbearing age suggest a potential risk for vertical transmission of HCV. These findings highlight the importance of following current CDC recommendations to identify, counsel, and test persons at risk for HCV infection (1,7), including pregnant women, as well as consider developing public health policies for routine HCV testing of pregnant women, and expanding current policies for testing and monitoring children born to HCV-infected women. Expansion of HCV reporting and surveillance requirements will enhance case identification and prevention strategies.

INTRODUCTION: Couples’ voluntary HIV counseling and testing (CHTC) is an HIV risk reduction strategy not widely available in the US. METHODS: We assessed willingness to participate in CHTC among US HIV-infected clinic patients via tablet-based survey and among HIVnegative persons with HIV-infected partners in care via mixed-method phone interviews. RESULTS: Most of the N=64 HIV-infected partners surveyed were men (89%), on antiretroviral treatment (ART) (92%), and many selfidentified homosexual (62%). We observed high levels of willingness to participate in CHTC (64%) among HIV-infected partners. Reasons for not wanting to participate included perceived lack of need (26%), desire to self-disclose their status (26%), and fear of being asked sensitive questions with their partner present (17%). HIV-infected partners were interested in discussing ART (48%), other sexually transmitted infections (STIs) (44%), and relationship agreements like monogamy (31%) during CHTC sessions. All N=15 HIV-negative partners interviewed were men, most identified as homosexual (73%), and about half (54%) reported consistent condom use with HIV-infected partners. We observed high levels of willingness to participate in CHTC (87%) among HIV-negative partners, who were also interested in discussing ART (47%), other STIs (47%), mental health services (40%), and relationship agreements (33%). Most negative partners (93%) indicated that they believed their HIV-infected partner was virally suppressed, but in the event that they were not, many (73%) were willing to take pre-exposure prophylaxis (PrEP). CONCLUSION: These results indicate that CHTC for serodiscordant couples is acceptable and should emphasize aspects most pertinent to these couples, such as discussion of ART/PrEP, STIs, and relationship agreements.

The burden of fatal liver disease is increasing in the estimated 3.2 million adults chronically infected with hepatitis C virus (HCV) in the United States (1–3). Sofosbuvir (Sovaldi, Gilead Sciences), which was approved by the U.S. Food and Drug Administration in December 2013, is a new oral HCV treatment that, when combined with other therapies, has a therapeutic efficacy (cure) greater than 90% across the 4 major HCV genotypes, limited adverse effects, and a shorter treatment window (usually 12 weeks) than its interferon-based predecessors (4). However, this drug currently retails at $84 000 per patient, forcing many payers to ration this lifesaving treatment. As such, Medicaid programs, which cover approximately 25% of patients with HCV infection who are hospitalized but have limited budgets, face the challenge of deciding who should receive new, costly treatments (4, 5). | To understand policies that might affect patient access to new HCV therapies, we obtained preferred drug lists and prior authorization criteria from state Medicaid fee-for-service program Web sites and, when these were unavailable, elicited feedback from Medicaid programs through direct communication. We compared the guidelines used by state Medicaid programs with those published by the Infectious Diseases Society of America (IDSA) and the American Association for the Study of Liver Diseases (AASLD) (www.hcvguidelines.org). On the basis of data collected from May through November 2014, Medicaid programs in 31 states had designated sofosbuvir a "nonpreferred" drug, the prescription of which requires that clinicians provide evidence of medical necessity as defined by state-specific laws. Seventeen states applied a "preferred" designation, and although demonstrated medical necessity is not necessarily required in these states, all but 2 required clinicians to seek "prior authorization" for sofosbuvir prescription (Table ).
