Treatment of chronic hepatitis C virus infection in the United States: some remaining obstacles

The effect of cognitive emotion regulation on direct-acting antivirals adherence in patients with hepatitis C

INTRODUCTION

Adherence to direct-acting antivirals (DAAs) could be a predictor of chronic viral hepatitis C (HCV) therapeutic failure. We examined the perceptions of patients receiving DAAs to determine how cognitive factors influence their decision to maintain adherence. Also, we explored the threshold of DAAs adherence for obtaining sustained virologic response (SVR) among patients with HCV, in order to better implement a strategy that improves the DAAs adherence in the future clinical practice.

METHODS

A single-arm prospective study was performed. Patients with HCV that started and completed DAAs treatment in the County Hospital of Craiova, Dolj, Romania, were enrolled. Patients' medication adherence was assessed using the HCV-AD10 questionnaire, and the cognitive emotion regulation was measured with CERQ questionnaire (five positive/adaptive cognitive emotion-regulation domains and four negative/maladaptive domains). Spearman correlation analysis was conducted to explore the relationships between adherence and different factors. ROC-curves were used to evaluate the adherence threshold to achieve SVR. A linear regression model was performed to analyze the primary outcome (DAAs adherence) to be the target variable based on given independent variables (age, treatment duration, severity of HCV, the nine adaptive and maladaptive strategies).

RESULTS

368 patients (mean age: 61 years) with HCV diagnosed 4.05 ± 6.38 (average) years ago were enrolled. Mean (±SD) adherence via HCV-AD10 was 91.51 ± 8.34, and the proportion of the participants achieving SVR was 96%. Patients with an adherence less than 84% (5 patients, 1.36%) was considered nonadherent and they have a high probability of not achieving response (sensitivity and specificity of 83% and 80%, respectively). We obtained significantly higher values of three adaptive strategies between adherent and nonadherent patients following DAAs treatment: in positive refocusing (p-value = 0.044), refocus on planning (p-value = 0.037), and positive reappraisal (p-value = 0.047).

DISCUSSION

The interplay between the three adaptive strategies of the cognitive emotion regulation and the enhancement of DAAs adherence contributes to a more holistic comprehension of patient behavior in the context of HCV treatment. Increasing refocusing and planning using goal setting and assisting patients in establishing specific, achievable goals can be crucial strategies for clinicians aiming to improve adherence among their patients.

Impact of a digital medicine programme on hepatitis C treatment adherence and efficacy in adults at high risk for non-adherence

BACKGROUND

Direct-acting anti-virals (DAA) are highly effective for hepatitis C virus (HCV) treatment, but perceived risks of medication non-adherence may restrict access to care. Digital medicine programme (DMP) has improved adherence and outcomes for some conditions.

AIMS

To conduct a prospective, single-arm, open-label study across the United States to assess the impact of DMP on adherence and efficacy in adults with chronic HCV infection at high risk for non-adherence.

METHODS

Eligible participants were placed on the DMP to evaluate real-time adherence; primary outcome was sustained virological response (SVR) at ≥10 weeks post-treatment.

RESULTS

Between August 2017 and April 2019, 288 participants (Medicaid, 64.9%; psychiatric disorders, 61.1%; homeless, 9.4%) received DAAs for 8-12 weeks (sofosbuvir/velpatasvir or ledipasvir, 45%; glecaprevir/pibrentasvir, 55%). SVR was achieved in 99.1% of 218 participants who had HCV RNA assessed at ≥10 weeks post-treatment; of the 70 participants who did not have SVR assessed, 17 had SVR4 with HCV RNA assessed at a median (IQR; interquartile range) 5.6 weeks (4.1, 7.9) post-treatment; one completed treatment but did not have HCV RNA assessed, and 52 discontinued treatment early without assessment. Overall, the primary analysed participants (n = 218) actively used the DMP for median (range) 92.9% (12.5%, 100%) of their prescribed treatment time, and overall pill-taking adherence was 95.0% (57.1%, 100%). Participants reported the programme was useful and easy to use through satisfaction surveys.

CONCLUSIONS

HCV treatment with DMP was accepted by patients and clinicians and may support HCV treatment outcomes among patients at high risk for treatment non-adherence (Clinical trials.gov NCT03164902).

Hepatitis C among blood donors: cascade of care and predictors of loss to follow-up

OBJECTIVE

To investigate the HCV cascade of care and to identify the factors associated with loss or absence to follow-up of patients identified as infected with hepatitis C through blood donation.

METHODS

Blood donors from 1994 to 2012, identified with positive anti- HCV by enzyme immunoassay and immunoblot tests were invited to participate in the study, through letters or phone calls. Patients who agreed to participate were interviewed and their blood samples were collected for further testing. The following variables were investigated: demographic data, data on comorbidities and history concerning monitoring of hepatitis C. Multiple regression analysis by Poisson regression model was used to investigate the factors associated with non-referral for consultation or loss of follow-up.

RESULTS

Of the 2,952 HCV-infected blood donors, 22.8% agreed to participate: 394 (58.2%) male, median age 48 years old and 364 (53.8%) Caucasian. Of the 676 participants, 39.7% did not receive proper follow-up or treatment after diagnosis: 45 patients referred not to be aware they were infected, 61 did not seek medical attention and 163 started a follow-up program, but were non-adherent. The main reasons for inadequate follow-up were not understanding the need for medical care (71%) and health care access difficulties (14%). The variables showing a significant association with inadequate follow-up after multiple regression analysis were male gender (PR = 1.40; 95%CI 1.15–1.71), age under or equal to 50 years (PR = 1.36; 95%CI 1.12–1.65) and non-Caucasians (PR = 1.53; 95%CI 1.27–1.84).

CONCLUSIONS

About 40.0% of patients did not receive appropriate follow-up. These data reinforce the need to establish strong links between primary care and reference centers and the need to improve access to specialists and treatments.

Barriers to Treatment Among New York City Residents with Chronic Hepatitis C Virus Infection, 2014

OBJECTIVE

New, highly effective hepatitis C virus (HCV) medications recently changed the landscape of HCV treatment. Access to treatment, however, is limited. The New York City Department of Health and Mental Hygiene conducted an enhanced surveillance project to better understand the reasons patients are not treated for HCV.

METHODS

In June 2014, we randomly selected 300 adults who were reported through routine surveillance as having a positive HCV ribonucleic acid test result and who had seen a medical provider since June 2012. We collected information on demographics, treatment, and barriers to treatment from these 300 patients and their providers by telephone, fax, mail, and medical record review.

RESULTS

Of 179 providers, 74 (41%) cited co-occurring conditions and 50 (28%) cited patients not keeping follow-up or referral appointments with specialists as common barriers to treatment. Forty providers (22%) reported that they do not prescribe HCV medications and instead refer patients to specialists for treatment. Of 89 patients citing barriers to treatment, 30 (34%) cited co-occurring conditions, 26 (29%) cited concerns about side effects, 21 (24%) indicated not feeling sick, 15 (17%) cited waiting for a better treatment regimen, and 12 (13%) cited medication costs or insurance issues. Only 11 providers and 10 patients denied any barriers to treatment.

CONCLUSION

Increasing the number of New York City residents with HCV infection who are treated and cured will require programs to increase provider capacity, change provider behavior in treating patients with substance use and medical conditions, improve patient awareness of new medications, provide patient navigation and care coordination support through treatment, and initiate advocacy and policy work.

Era of direct acting antivirals in chronic hepatitis C: Who will benefit?

In the era of highly effective direct acting antiviral (DAA) drugs for the treatment of chronic hepatitis C (CHC) infection, where eradication is almost ensured with minimal side effects, all hepatitis C carriers should benefit theoretically. In the real world setting however, only a small proportion will benefit at this time point due to the multiple barriers to accessing therapy. Given that universal treatment is unlikely, treatment with DAAs will likely be restricted to those with the highest health benefits, and for those who can afford the high expense of a treatment course. Those with the highest unmet needs include those who have failed previous interferon-based therapy or who are interferon-ineligible with evidence of active disease, those with advance liver disease, and those with recurrence of hepatitis C after liver transplantation. In the future, the focus should be on increasing access to treatment for those infected with CHC.

Personality disorders do not affect treatment outcomes for chronic HCV infection in Spanish prisoners: the Perseo study

Background

The link between infection with hepatitis C virus (HCV) and personality disorders (PD) has not been investigated in detail. The aim of this study was to compare the effectiveness of HCV treatment in prisoners with and without PD.

Methods

We performed a prospective multicentre study in inmates from 25 Spanish prisons who had been treated with pegylated interferon alfa-2a plus ribavirin in 2011. PD diagnosis was based on the Personality Diagnostic Questionnaire-4+. We calculated adjusted Odds Ratios (AOR) and 95 % confidence intervals (95 % CI) using logistic regression.

Results

The sample included 236 patients (mean age: 40.3 years, 92.8 % male, 79.2 % intravenous drug users, and 26.3 % HIV-coinfected). The prevalence of PD was 72.5 %. 32.2 % of patients discontinued treatment; this percentage was higher in patients with HCV genotypes 1/4 (AOR = 3.55; CI:1.76–7.18) and those without PD (AOR = 2.51; 1.23–5.11). Treatment discontinuation was mainly for penitentiary reasons (40.3 %): release or transfer between prisons.

The rate of sustained viral response (SVR) was 52.1 % by ITT and 76.9 % by observed treatment (OT). SVR was higher among patients with genotype 2 or 3, and those with low baseline HCV-RNA. We did not observe any differences between individuals with and without PD in term of SVR, HCV genotype or HIV infection.

Conclusions

Our results support the safety and clinical effectiveness of the treatment of chronic HCV infection in correctional facilities, both in prisoners with PD and those without. Our data support non-discrimination between patients with and without PD when offering treatment for HCV infection to prison inmates.

Results from a Geographically Focused, Community-Based HCV Screening, Linkage-to-Care and Patient Navigation Program

BACKGROUND

Many of the five million Americans chronically infected with hepatitis C (HCV) are unaware of their infection and are not in care.

OBJECTIVE

We implemented and evaluated HCV screening and linkage-to-care interventions in a community setting.

DESIGN

We developed a comprehensive, community-based HCV screening and linkage-to-care program in a medically underserved neighborhood with high rates of HCV infection in Philadelphia, Pennsylvania. We provided patient navigation services to enroll uninsured patients in insurance programs, facilitate referrals from primary care physicians and link patients to an HCV infectious disease specialist with intention to treat and cure.

PATIENTS

Philadelphia residents were recruited through street outreach.

MAIN MEASURES

We measured anti-HCV seroprevalence and diagnosis, linkage and retention in care outcomes for chronically infected patients.

KEY RESULTS

We screened 1,301 participants for HCV; anti-HCV seroprevalence was 3.9 % and 2.8% of all patients were chronically infected. Half of chronically infected patients were newly diagnosed; the remaining patients were aware of infection but not in care. We provided confirmatory RNA testing and results, assisted patients with attaining insurance and linked most chronically infected patients to a primary care provider. The biggest barrier to retaining patients in care was obtaining referrals for subspecialty providers; however, we obtained referrals for 64% of chronically infected participants and have retained most in subspecialty HCV care. Several have commenced treatment.

CONCLUSIONS

Non-clinical screening programs with patient navigator services are an effective means to diagnose, link, retain and re-engage patients in HCV care. Eliminating referral requirements for subspecialty care might further enhance retention in care for patients chronically infected with HCV.

The Hepatitis C treatment experience: Patients' perceptions of the facilitators of and barriers to uptake, adherence and completion

OBJECTIVE

This study explores the perceptions of patients receiving treatment for Hepatitis C to determine what factors influence their decision to commence treatment, ability to maintain adherence and complete their treatment program.

DESIGN

Semi-structured interview techniques were used in a qualitative study of 20 patients undergoing treatment for Chronic Hepatitis C (CHC).

MAIN OUTCOME MEASURES

To explore patients' perceived barriers and facilitators of Hepatitis C treatment adherence and completion.

RESULTS

Analysis of patient interviews identified four key themes: (1) motivations for commencing CHC treatment - fear of death and ridding themselves of stigma and shame; (2) the influential role of provider communication - patients reported that information and feedback that was personalised to their needs and lifestyles was the most effective for improving adherence to treatment; (3) facilitators of treatment adherence and completion - social, emotional and practical support improved adherence and completion, as did temporarily ceasing employment; (4) barriers to treatment adherence and completion - these included side effects, stigma, a complicated dosing schedule and limitations of the public healthcare system.

CONCLUSION

To increase treatment adherence and completion rates, a patient-centred approach is required that addresses patients' social, practical, and emotional support needs and adaptive coping strategies.

"Test, Listen, Cure" (TLC) Hepatitis C Community Awareness Campaign

BACKGROUND

Improved drugs have been approved for the treatment of hepatitis C virus (HCV), but many people are unaware of improved therapies that are now available to cure the illness in a high percentage of patients.

OBJECTIVE

The objectives of the Test, Listen, Cure (TLC) Hepatitis C Community Awareness Campaign include the development and implementation of a health education and promotion campaign in Memphis, Tennessee, and surrounding areas of western Tennessee, eastern Arkansas, and northern Mississippi, to increase community awareness about HCV, and to provide up-to-date provider education on HCV screening and treatment. The health education and promotion campaign, which will be conducted in collaboration with area hospitals, clinics, and nonprofit organizations, will provide information about how HCV infection is transmitted, risk factors for the disease, the importance of screening and treatment, and the availability of improved treatment for the disease. A second objective will be to provide continuing professional education on HCV screening and treatment to a minimum of 200 area health care providers, including primary care and internal medicine physicians and residents, physician assistants, nurse practitioners, providers who care for homeless persons, and dialysis unit nurses.

METHODS

Health education materials will be developed for this community awareness campaign that is culturally appropriate for African Americans and suitable for people with lower health literacy and educational attainment. Information will be compiled and disseminated about area providers who provide screening services and treatment for persons with HCV in order to facilitate linkages to care. Four focus groups of 8-10, African American adults aged 40-64, will be conducted to test the health education materials. The provider education on HCV will also address patient-physician communication and cultural competency. The National Medical Association regional chapters and expert physician consultants will provide assistance with delivering the education program.

RESULTS

Results from this one year project will be available in early 2016.

CONCLUSIONS

Depending on the availability of funding and successful implementation of the project, the TLC campaign will be extended to similar cities in the United States.
