Effects of Viral Eradication With Ledipasvir and Sofosbuvir, With or Without Ribavirin, on Measures of Fatigue in Patients With Chronic Hepatitis C Virus Infection

Assessment of fatigue and its impact in chronic liver disease

Patient-reported outcomes (PROs), such as health-related quality of life (HRQL), are important outcome measures for patients with chronic liver diseases (CLDs). Presence of cirrhosis and advanced liver disease have been associated with worsened HRQL and fatigue. On the other hand, some patients with earlier stages of CLD also experience fatigue, causing PRO impairment. Treatment for some CLDs may improve HRQL and, sometimes, levels of fatigue. We aimed to provide an in-depth expert review of concepts related to fatigue and HRQL in patients with primary biliary cholangitis, hepatitis C virus and MASLD (metabolic dysfunction-associated steatotic liver disease). A panel of experts in fatigue and CLD reviewed and discussed the literature and collaborated to provide this expert review of fatigue in CLD. Herein, we review and report on the complexity of fatigue, highlighting that it is comprised of peripheral (neuromuscular failure, often in conjunction with submaximal cardiorespiratory function) and central (central nervous system dysfunction) causes. Fatigue and HRQL are measured using validated self-report instruments. Additionally, fatigue can be measured through objective tests (e.g. grip strength). Fatigue has deleterious effects on HRQL and one's ability to be physically active and socially engaged but does not always correlate with CLD severity. Treatments for hepatitis C virus and MASLD can improve levels of fatigue and HRQL, but current treatments for primary biliary cholangitis do not seem to affect levels of fatigue. We conclude that obtaining PRO data, including on HRQL and fatigue, is essential for determining the comprehensive burden of CLD and its potential treatments.

Symptoms of Liver Disease During Tenofovir Therapy With or Without Peginterferon: Results from the Hepatitis B Research Network Immune Active Trial

AIMS

Evaluate patient-reported liver symptoms during treatment for chronic hepatitis B viral (HBV) infection and associations between changes in symptoms and levels of alanine aminotransferase (ALT) and viral markers.

METHODS

Data from 200 participants in the Hepatitis B Research Network Immune Active Trial who completed symptom assessments were analyzed. Patients were treated with tenofovir, with or without peginterferon (TDF + PegIFN vs. TDF alone) for 192 weeks. Participants completed a Symptom Checklist at baseline and every 4-12 weeks. A total symptom score was created, ranging from 0 (none) to 40 (severe). The SF-36 was completed every 48 weeks. Associations of symptom scores with ALT and viral markers were evaluated at baseline and end of treatment.

RESULTS

Participants were 65% male, 83% Asian, with a mean age of 42. Baseline symptoms were mild (median = 2, range 0-25) and associated with baseline ALT, HBV DNA levels and HBeAg + status. Patients on TDF alone experienced a more rapid and greater improvement in symptoms, but by week 192, symptom improvement was similar in both groups (54% vs 36%). Symptom improvements correlated with ALT and HBV DNA, most markedly among those with symptoms at baseline. Most patients (4 out of 6) who achieved HBsAg loss experienced symptom improvements. Overall, SF-36 scores did not change with treatment.

CONCLUSIONS

Reduction in ALT and HBV DNA levels with therapy are associated with significant improvement in liver symptoms such as fatigue and pain over the liver, especially among those with higher ALT, HBV DNA, symptoms and HBeAg + status prior to treatment.

Severe, Persistent, Disruptive Fatigue Post-SARS-CoV-2 Disproportionately Affects Young Women

Introduction

Post-acute SARS-CoV-2 (PASC) symptoms are often persistent, disruptive, and difficult to treat effectively. Fatigue is often among the most frequently reported symptoms and may indicate a more challenging road to recovery.

Purpose

To describe the natural history, symptomology, and risk profile of long-term post-acute SARS-CoV-2.

Patients and Methods

Participants treated for SARS-CoV-2 within a large, community health system in the US were enrolled prospectively in a longitudinal, observational PASC study examining participants at enrollment and 6 months. Medical history, symptom reporting, validated measures of cognition, and patient-reported outcomes (PROs), were performed for all participants and repeated during study follow-up visits.

Results

A total of 323 participants completed baseline evaluations. Sixty one participants indicated clinically significant fatigue (23.1% at baseline); a representative sample of 141 enrollees also completed a baseline Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) in-depth fatigue reporting questionnaire, 37 had severe fatigue. The severely fatigued (FACIT-F ≤29.7) were significantly younger, female, had more anxiety and depression, had a higher resting heart rate, reported more sick days, and were less physically active post-COVID. They were more likely to have a diagnosis of chronic kidney disease (13.5% vs 2.9%) but less likely to have a history of cancer (8.1% vs 23.1). Participants who were severely fatigued reported health, diet, weight, and sleep were worse than those not severely fatigued post-COVID (p = 0.02 to 0.0002). Fatigue was significantly correlated with impairment of all PROs administered after COVID-19 infection.

Conclusion

Fatigue is a common symptom post-COVID-19 infection and is associated with lower reported well-being and function. Those with severe fatigue tended to be younger and female and have a past medical history of anxiety, depression, kidney disease, and more sedentary lifestyles.

The Potential Role of Fatigue in Identifying Patients With NASH and Advanced Fibrosis Who Experience Disease Progression

BACKGROUND AND AIMS

Fatigue is common in patients with advanced liver disease. We investigated fatigue and clinical outcomes among patients with advanced nonalcoholic steatohepatitis (NASH).

METHODS

In this study, patients with biopsy confirmed NASH and bridging fibrosis (F3) or compensated cirrhosis (F4) were followed for up to 2 years. The Chronic Liver Disease Questionnaire for Nonalcoholic Steatohepatitis (CLDQ-NASH) fatigue domain at baseline (range, 1-7; lower score indicating worse fatigue) quantified fatigue. The Cox proportional hazards model was used to study time to liver-related clinical events (progression to histologic cirrhosis or hepatic decompensation in F3, hepatic decompensation in F4).

RESULTS

Of the 1679 NASH patients with fibrosis, 802 had F3 and 877 had F4 (58 ± 9 years of age, 40% male, 74% type 2 diabetes). During median follow-up of 16 months (interquartile range, 14-18), 15% (n = 123) of NASH F3 patients experienced liver-related events and 3.5% (n = 31) of NASH F4 patients experienced hepatic decompensation. Mean baseline CLDQ-NASH fatigue score in F3 patients was 4.77 ± 1.36; NASH F3 patients who experienced liver-related events had lower baseline scores: 4.47 ± 1.36 vs 4.83 ± 1.35 (P = .0091). The mean fatigue score in F4 was 4.56 ± 1.44; these scores were lower in patients who decompensated in follow-up: 3.74 ± 1.31 vs 4.59 ± 1.43 (P = .0011). The association of lower fatigue scores and risk of liver-related or decompensation events was significant after adjustment for confounders (adjusted hazard ratio per 1 point in fatigue score in F3, 0.85; 95% confidence interval, 0.74-0.97; P = .02; adjusted hazard ratio in F4, 0.62; 95% confidence interval, 0.48-0.81; P = .0004).

CONCLUSION

Worse fatigue at baseline is associated with a higher risk of adverse clinical events in patients with NASH-related advanced fibrosis and cirrhosis.

Health-related quality of life in Cuban patients with chronic liver disease: A real-world experience

INTRODUCTION AND OBJECTIVES

Patient-reported outcomes (PROs) are important for comprehensive assessment of chronic liver disease (CLD). Latin America and the Caribbean have a high burden of CLD, but PROs are lacking. We assessed health-related quality of life (HRQL) in Cuban patients with compensated CLD.

MATERIALS AND METHODS

A cross sectional study performed of adult patients with a diagnosis of chronic viral infection B and C (HBV, HCV), non-alcoholic fatty liver diseases (NAFLD) and autoimmune liver diseases (AILD) including autoimmune hepatitis (AIH), primary biliary cholangitis (PBC) and overlap syndrome (AIH+PBC). PROs were collected using: Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F), Work Productivity and Activity-Specific Health Problem (WPAI: SHP), and the Chronic Liver Disease Questionnaire (CLDQ)-disease-specific.

RESULTS

543 patients enrolled, n=91 (HBV), n=188 (HCV), n=221 (NAFLD), n=43 (AILD). Of those with AILD, 22 had AIH, 14 PBC, and 7 overlap AIH/PBC. Mean age was 53.5 years, 64.1% female, 69.2% white, and 58.0% employed. Patients with HCV and AILD had more severe liver disease. A significant impairment in PROs was observed in HCV group whereas the AILD patients had more activity impairment. CLDQ-HRQL scores were significantly lower for patients with NAFLD and AILD compared to HBV. Male gender and exercising ≥90min/week predicted better HRQL. The strongest independent predictors of HRQL impairment were fatigue, abdominal pain, anxiety, and depression (p<0.05).

CONCLUSIONS

HRQL for Cuban patients with compensated CLD differs according to the CLD etiology. Patients with HCV and AILD had the worst PRO scores most likely related to severe underlying liver disease and/or extrahepatic manifestations.

Chronic hepatitis D associated with worse patient-reported outcomes than chronic hepatitis B

BACKGROUND & AIMS

Health-related quality of life (HRQoL) determined by patient-reported outcomes (PROs) is impaired in chronic hepatitis B (CHB) and C patients, but there are no data regarding patients with chronic hepatitis D (CHD). The aim of this study was to assess PRO scores in untreated patients with CHD and compare them with those obtained for patients with CHB.

METHODS

Patients with CHD completed 3 PRO instruments (Chronic Liver Disease Questionnaire [CLDQ], Functional Assessment of Chronic Illness Therapy-Fatigue [FACIT-F], and Work Productivity and Activity Impairment [WPAI]), and the results were compared with those of patients mono-infected with CHB.

RESULTS

In total, 125 patients were included: 43 with CHD and 82 with CHB. Overall, baseline PROs showed differences between both groups. Several assessments, such as the worry score from CLDQ (p = 0.0118), functional well-being from FACIT-F (p = 0.0281), and activity impairment from WPAI (p = 0.0029) showed a significant trend to worse scores in patients with CHD than with CHB. In addition, the linear regression model supports the finding that having CHD as opposed to having CHB was a predictor of a higher worry score (CLDQ) and a higher activity impairment (WPAI).

CONCLUSIONS

In this first assessment in CHD, PROs recorded in patients with CHD showed a significant impairment in some domains of HRQoL questionnaires in comparison with those with CHB. Studies in larger cohorts with lengthier follow-up are needed to fully assess patient-reported quality of life over the course of CHD.

LAY SUMMARY

Chronic hepatitis D (CHD) is a viral disease that causes rapid evolution to liver cirrhosis, amongst other severe complications, when compared to patients with chronic hepatitis B (CHB). Health-related quality of life in chronic hepatitis C and CHB has been reported widely, but no studies have been performed on patient-reported outcomes in patients with CHD. Results showed that CHD patients reported worse outcomes in psychological domains such as worry and emotional well-being, as well as in physical domains such as abdominal symptoms, physical well-being, and activity impairment in comparison with patients with CHB.

Changes in clinical scenarios, management, and perspectives of patients with chronic hepatitis C after viral clearance by direct-acting antivirals

INTRODUCTION

Hepatitis C virus (HCV) causes a systemic infection inducing hepatic and extrahepatic diseases. These latter involve cardiovascular system, kidney, brain, endocrine, glucose, and lipid metabolism, and the immune system. HCV infection is associated with an increased risk of morbidity and mortality for both hepatic and extrahepatic events. Direct-acting antivirals (DAA), introduced in the most recent years for HCV treatment, are effective in up to 99% of cases and have changed the clinical scenarios and management of these patients.

AREAS COVERED

The literature on the impact of HCV clearance by DAA on both hepatic and extrahepatic disease outcomes has been analyzed and discussed in this review in order to summarize the full therapeutic potential and its weaknesses.

EXPERT OPINION

Patients achieving HCV clearance have improved hepatic and extrahepatic diseases, quality of life and survival. They have lower incidence of cardiovascular disease, type 2 diabetes, kidney damage, and immuno-mediated manifestations. However, the improvements are related to the degree of pre-treatment organ damage. Therefore, a significant percentage of patients with advanced disease remains at risk of morbidity and mortality and must be monitored in the post-treatment. In addition, data emphasize the importance of starting treatment during the early stages of HCV infection.

Evolution of Hepatitis C Virus Treatment During the Era of Sofosbuvir-Based Therapies: A Real-World Experience in France

BACKGROUND

Treatment of hepatitis C virus (HCV) has been dramatically improved with the introduction of direct-acting antiviral agents (DAAs). Universal access to pangenotypic DAAs was provided in France from 2017, expanding the type of patients treated. Real-world studies are important to confirm effectiveness and safety in clinical practice, particularly in vulnerable populations.

AIMS

To assess real-world effectiveness and safety of sofosbuvir-based therapy in adults with chronic HCV infection before and after universal access to DAAs in France.

METHODS

This multicenter, non-interventional, prospective study assessed the effectiveness, safety, patient-reported outcomes and adherence with sofosbuvir-based regimens from October 2015 to July 2016 (Period 1: sofosbuvir-based therapy excluding sofosbuvir/velpatasvir) and from October 2017 to July 2018 (Period 2: pangenotypic sofosbuvir/velpatasvir-based therapy).

RESULTS

Baseline data were documented for 1029 patients. Overall, 797 (77%) had sustained virologic response data available ≥ 9 weeks after treatment completion. Per protocol response was high (97%) irrespective of age, alcohol consumption, recreational drug use, or HIV/HCV coinfection. Adverse events occurred in approximately 25% of patients with the majority experiencing Grade 1 or 2 events. Sofosbuvir-based regimens improved health-related quality of life from baseline to end of treatment in patients with data at all timepoints. Overall, 99% of patients reported total or almost total adherence to therapy.

CONCLUSIONS

Sofosbuvir-based therapy, including pangenotypic sofosbuvir/velpatasvir, is effective for the treatment of HCV in real-world clinical practice. This is an important step towards HCV elimination.

[Neurological complications of hepatitis C infections]

Die chronische Hepatitis-C-Virus(HCV)-Infektion ist eine hochprävalente Systemerkrankung, die verschiedene neurologische Komplikationen verursachen kann. Es lassen sich HCV-assoziierte Symptome im zentralen und peripheren Nervensystem sowie der Muskulatur unterscheiden. Wichtige Pathomechanismen sind die HCV-assoziierte Autoimmunität (z. B. gemischte Kryoglobulinämie mit Polyneuropathie) und direkte Neurotoxizität (z. B. bei HCV-assoziierten kognitiven Defiziten). Die häufigsten neurologischen Komplikationen sind distal-symmetrische Polyneuropathien, Small-fiber-Neuropathien und kognitive Defizite. Die HCV-Infektion stellt außerdem einen Risikofaktor für ischämische und hämorrhagische Schlaganfälle sowie den Morbus Parkinson dar. Die frühe Identifikation und antivirale Behandlung HCV-positiver Patienten steht im Zentrum der Behandlung. Durch neue antivirale Therapien können >90 % der Patienten dauerhaft von der HCV-Infektion geheilt werden.

Quality of life in patients with hepatitis C. Importance of treatment

Chronic hepatitis C virus infection is a systemic disease that impairs the quality of life of affected individuals. The impairment is not only due to physiological factors, such as the non-hepatic manifestations of the disease or certain symptoms such as fatigue, weakness and nausea, but is also due to the substantial psychological impact of the infection. Treatment with direct-acting antivirals (DAA) has been demonstrated to substantially improve patient's quality of life, starting in the initial phases.

Impact of Direct Acting Antiviral Agent Therapy upon Extrahepatic Manifestations of Hepatitis C Virus Infection

PURPOSE OF REVIEW

Direct acting antiviral agents (DAAs) have emerged as simple, short, safe, and effective treatments for chronic hepatitis C (CHC) infection. CHC is a systemic disease with frequent and multiple extrahepatic manifestations. The beneficial effects of DAA treatment regimens extend beyond improvement in liver-related outcomes to amelioration of extra hepatic manifestations and are likely to have economic implications. The purpose of this review is to evaluate the effect of DAAs on extra hepatic manifestations of CHC virus infection.

RECENT FINDINGS

Recent studies indicate that DAAs are associated with reduction in all-cause mortality, even in patients without significant hepatic fibrosis. They are also associated with reduction in incident cardiovascular disease and diabetes. DAAs are the mainstay of treatment in HCV-associated cryoglobulinemia and lymphoma. Successful HCV therapy with DAAs also improves patient-related outcomes such as health-related quality of life. DAAs improve extrahepatic manifestations of CHC virus infection. Future studies are needed to evaluate the long-term durability of treatment response and for accounting amelioration of extrahepatic manifestations into the cost effectiveness of DAA regimens.

Hepatitis C Virus Infection in Children and Pregnant Women: An Updated Review of the Literature on Screening and Treatments

Objective  The aim of the paper is to review the current information relating to the diagnosis and treatment of hepatitis C virus (HCV) infection in pregnant women and children, particularly those infected by mother-to-child transmission. Study Design  A review of published literature was performed to identify relevant articles published between January 2015 and March 2019 on: HCV infection in pregnant woman, mother-to child-transmission of HCV and HCV infection in pediatrics. The results of the evaluation of the different studies were summarized in two sections describing separately the screening and effective treatments in pregnant women and children. Results  The rate of mother-to-child transmission of HCV is approximately 5%. HCV infection is strongly associated with cholestasis and preterm birth. Prenatal diagnosis of hepatitis C virus has a dual benefit for mother and child. Perinatally infected children develop cirrhosis in earlier age than those who acquire HCV as adolescents. Pregnant women with cirrhosis have a higher risk of poor maternal and neonatal outcomes than those without cirrhosis. Conclusion  To improve public health, universal screening of pregnant women for HCV infection should be performed. Early identification of women and children with HCV infection is important to enable them to be included in assessment and/or treatment programs.

Hepatitis C in Patients With Minimal or No Hepatic Fibrosis: The Impact of Treatment and Sustained Virologic Response on Patient-Reported Outcomes

Background

While the necessity of treatment of hepatitis C virus (HCV)-infected patients with advanced liver disease is widely accepted, the benefit of treating patients without significant liver disease is less well established. Our aim was to assess the effect of treating HCV in patients with no or minimal fibrosis (Metavir stage F0-F1) on patient-reported outcomes (PROs).

Methods

HCV-infected patients with F0-F1 from 16 clinical trials were included. PROs were collected before, during, and after treatment.

Results

A total of 1548 HCV-infected patients with F0-F1 were included (mean age 46 years, 43% male, 81% treatment-naive). Patients were treated with interferon (IFN) + sofosbuvir (SOF) + ribavirin (RBV) (n = 91) or SOF + RBV with or without ledipasvir (n = 479) or IFN- and RBV-free regimens with SOF + ledipasvir or SOF + velpatasvir or SOF + velpatasvir + voxilaprevir (n = 978). By the end of treatment, patients receiving IFN-containing regimens experienced significant decreases in most PRO domains (-4.5 to -28.7 on a 0-100 scale), while subjects treated with IFN-free RBV-containing regimens had a modest impairment (-2.3 to -8.9) (P ≤ .01). In contrast, treatment with regimens without IFN and RBV led to PRO improvements (+1.2 to +10.9). Regardless of the regimen, sustained virologic responses (SVRs) at 12 and 24 weeks were universally associated with PRO improvements (+2.1 to +14.7, P < .0001.

Conclusions

HCV-infected subjects with no or minimal fibrosis treated with IFN- and RBV-free regimens experienced on-treatment and post-SVR PRO improvements.

Patient-reported outcomes in patients chronic viral hepatitis without cirrhosis: The impact of hepatitis B and C viral replication

BACKGROUND & AIM

Chronic infections with hepatitis B or C (HBV and HCV) are associated with adverse clinical outcomes and patient-reported outcomes (PROs). The aim is to compare PRO scores in patients with chronic HBV and HCV without advanced liver disease before and after suppression/clearance of their infection.

METHODS

Patients with HCV and HBV infection prior to initiation of antiviral treatment and after viral suppression/eradication completed PRO questionnaires.

RESULTS

We included 132 patients with HBV and 132 matched patients with HCV. Baseline PRO scores were significantly higher in patients with HBV in the domains of Physical Functioning, Role Physical, Bodily Pain, Social Functioning, and Role Emotional of SF-36, SF-6D utility, Emotional and Fatigue domains of CLDQ, Presenteeism and total Work Productivity Impairment of WPAI:SHP in comparison to patients with HCV by 5.8%-13.2% of a PRO score range (all P < 0.05). After viral suppression (HBV DNA < 20 IU/mL after 48 weeks of treatment for HBV) or eradication (SVR-12 for HCV), only Physical Functioning and Role Physical scores remained higher in HBV by 6.7%-9.9%, while other PRO scores became similar between HBV and HCV groups (P > 0.05). The most prominent improvement of PROs in HCV was noted in Vitality, Emotional, Fatigue and Worry domains. In addition, General Health, Worry and Work Productivity scores were the most improved in HBV.

CONCLUSIONS

Prior to treatment, PRO scores were lower in patients with HCV in comparison to HBV. After successful treatment, both groups of patients experienced improvement in some PRO domains confirming the positive impact of treatment.

Cytokine balance is restored as patient-reported outcomes improve in patients recovering from chronic hepatitis C

BACKGROUND & AIMS

Chronic hepatitis C (CHC) has a negative impact on patient-reported outcomes (PROs). Although most CHC patients who achieve sustained virologic response (SVR) show an improvement in PRO scores, some continue to experience impairment in PROs. The aim was to investigate if serum biomarkers (selected neurotransmitters and cytokines) are associated with changes in PROs in CHC patients who achieve SVR.

METHODS

Data were utilized from a prospective clinical trial of ledipasvir/sofosbuvir fixed-dose combination. Chronic genotype 1 HCV subjects without cirrhosis (N = 40, age: 45.3 ± 11.5, 48% male, 90% white) were treated for 12 weeks open label with 97% achieving SVR24. PRO questionnaires included Short Form-36 (SF-36), Fatigue Severity Scale (FSS), Beck Depression Inventory-II (BDI-II), Chronic Liver Disease Questionnaire-HCV (CLDQ-HCV) and Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F). Sera were used for measurement of selected neurotransmitters and cytokines. Data were collected at baseline and follow-up week 24.

RESULTS

Changes in physical health correlated with changes in several biomarkers. BDNF negatively correlated with SF-36 physical health summary score (rho = -0.34, P < 0.05), SF-36 physical functioning (rho = -0.34, P < 0.05), SF-36 bodily pain (rho = -0.39, P < 0.05) and FACIT-F physical well-being (rho = -0.54, P < 0.001). Changes in emotional well-being (FACIT-F) were positively associated with changes in serotonin (rho = 0.34, P < 0.05), but negatively associated with changes in GABA and BDNF (rho = -0.4, P = 0.01, and rho = -0.35, P < 0.05 respectively).

CONCLUSIONS

These data indicate relationships between PROs and serum biomarkers pre- and post-SVR in CHC. These concomitant changes may have important clinical relevance.

Importance of fatigue and its measurement in chronic liver disease

The mechanisms of fatigue in the group of people with non-alcoholic fatty liver disease and non-alcoholic steatohepatitis are protean. The liver is central in the pathogenesis of fatigue because it uniquely regulates much of the storage, release and production of substrate for energy generation. It is exquisitely sensitive to the feedback controlling the uptake and release of these energy generation substrates. Metabolic contributors to fatigue, beginning with the uptake of substrate from the gut, the passage through the portal system to hepatic storage and release of energy to target organs (muscle and brain) are central to understanding fatigue in patients with chronic liver disease. Inflammation either causing or resulting from chronic liver disease contributes to fatigue, although inflammation has not been demonstrated to be causal. It is this unique combination of factors, the nexus of metabolic abnormality and the inflammatory burden of non-alcoholic fatty liver disease and non-alcoholic steatohepatitis that creates pathways to different types of fatigue. Many use the terms central and peripheral fatigue. Central fatigue is characterized by a lack of self-motivation and can manifest both in physical and mental activities. Peripheral fatigue is classically manifested by neuromuscular dysfunction and muscle weakness. Therefore, the distinction is often seen as a difference between intention (central fatigue) versus ability (peripheral fatigue). New approaches to measuring fatigue include the use of objective measures as well as patient reported outcomes. These measures have improved the precision with which we are able to describe fatigue. The measures of fatigue severity and its impact on usual daily routines in this population have also been improved, and they are more generally accepted as reliable and sensitive. Several approaches to evaluating fatigue and developing endpoints for treatment have relied of biosignatures associated with fatigue. These have been used singly or in combination and include: physical performance measures, cognitive performance measures, mood/behavioral measures, brain imaging and serological measures. Treatment with non-pharmacological agents have been shown to be effective in symptom reduction, whereas pharmacological agents have not been shown effective.

Muscle performance and fatigue in compensated chronic liver disease

Background: A common and debilitating symptom in patients with chronic liver disease is fatigue (CLD). Muscle dysfunction has been suggested to be a key mechanism of fatigue in CLD. Objective: We aimed to evaluate fatigue and the potential association with muscle performance and physical activity in outpatients with CLD. Methods: Two-hundred seventy outpatients with CLD were included, (52 ± 15 years, mean ± SD; 151 females) with autoimmune hepatitis (n = 49), primary biliary cholangitis (n = 45), primary sclerosing cholangitis (n = 46), chronic hepatitis B (n = 57) or C (n = 73). Patients with a Child-Pugh >6 were excluded. The questionnaire Fatigue Impact Scale (FIS) was used to evaluate fatigue, and physical activity was evaluated through a self-reported level of physical activity. Muscle function was assessed with four muscle tests, walking speed, handgrip strength, standing heel-rise test (SHT) and 'Timed Up and Go' test (TUG). Results: The median total FIS score was 30 (40% had FIS > 40, considered high-fatigue). Diminished muscle performance was observed in the SHT (% of predicted value: 53 ± 26%) and with maximum grip strength (85 ± 20%). The FIS score was significantly different between groups of CLDs (p = .004). In multivariate analysis the TUG (p = .001), SHT (p = .005), antidepressants (p < .001), and level of physical activity (p = .001) were associated with fatigue (R² = 29%). Subjects with higher levels of physical activity had lower FIS (p < .001). Conclusions: In patients with CLD, fatigue was associated with low muscle performance and reduced level of physical activity, which could be a potential therapeutic target.

A Comprehensive Review of Patient-reported Outcomes in Patients With Chronic Liver Diseases

Chronic liver disease (CLD) is a global health problem with chronic viral hepatitis, alcohol-related liver disease, and nonalcoholic fatty liver disease being important causes of mortality. Besides its clinical burden, patients with CLD also suffer from impairment of their health-related quality of life and other patient-reported outcomes (PRO). In this context, a combination of both clinical and PROs will allow assessment of the comprehensive burden of liver disease on patients. PROs cannot be observed directly and must be assessed by validated questionnaires or tools. Various tools have been developed to accurately measure PROs in patients with CLD, including generic and disease-specific questionnaires such as Short Form-36, Chronic Liver Disease Questionnaire and its subtypes. It is important to note that PRO instruments can be used to appreciate the impact of the natural history of CLD or of treatment on patients' experiences. This review summarizes PRO assessment in different types of liver disease and different tools useful to investigators and clinicians who are interested in this aspect of patients' experience.

The comprehensive outcomes of hepatitis C virus infection: A multi-faceted chronic disease

Treatment of hepatitis C virus (HCV) infection has been revolutionized with the introduction of pangenotypic, interferon- and ribavirin-free regimens associated with high cure rates and a low side effect profile. Additionally, there is evidence that HCV cure reduces HCV complications, improves patient-reported outcomes and is cost-saving in most western countries in the long term. This is a review of the comprehensive burden of HCV and the value of eliminating HCV infection. With the introduction of the interferon-free all-oral, once a day pill treatment regimen for the cure of HCV, the potential to eliminate HCV by 2030 has become a possibility for some regions of the world. Nevertheless, there are barriers to screening, linkage to care, and treatment in many countries that must be overcome in order to reach this goal. In conclusion, globally, work must continue to ensure national policies are in place to support screening, linkage to care and affordable treatment in order to eliminate HCV.

French Patients with Hepatitis C Treated with Direct-Acting Antiviral Combinations: The Effect on Patient-Reported Outcomes

BACKGROUND

In addition to high efficacy, new anti-hepatitis C virus (HCV) regimens improve patient-reported outcomes (PROs), which must be considered by policymakers in different countries when deciding upon treatment coverage.

OBJECTIVE

To assess PROs of French patients with HCV treated with different antiviral regimens.

METHODS

French patients with HCV from 11 clinical trials were included. PROs were measured before, during, and after treatment (Short Form-36 version 2, Functional Assessment of Chronic Illness Therapy-Fatigue, Chronic Liver Disease Questionnaire-HCV, and Work Productivity and Activity Index: Specific Health Problem).

RESULTS

A total of 931 subjects (age 54 ± 10 years, 60.3% males, 55% employed, 33.5% cirrhotic, 50% treatment-naive, and 45.6% genotype 1) were treated with a combination of interferon, ribavirin, and sofosbuvir (IFN + RBV + SOF) (N = 11; excluded from comparisons), SOF/RBV ± ledipasvir (LDV) (N = 202), IFN/RBV-free (LDV/SOF, SOF/velpatasvir, or SOF/velpatasvir/voxilaprevir) (N = 594), or placebo (N = 124). The sustained virologic response 12 (SVR-12) rates were 87.1% for IFN-free RBV-containing regimens, 97.6% for IFN/RBV-free regimens, and 0% for placebo. Baseline PRO scores were not different across the treatment groups (all P > 0.10). At the end of treatment, patients treated with IFN-free SOF/RBV ± LDV experienced moderate declines in their PRO scores (up to -7.9% of a PRO range size; P < 0.05), and placebo-treated group did not have significant changes in their PROs (P > 0.05). In contrast, the IFN/RBV-free group experienced significant on-treatment improvement in most PROs (up to +7.9%; P < 0.05). Despite those on-treatment differences, most PROs improved with SVR-12 and SVR-24 regardless of the regimen. In comparison with matched controls from the United States treated with the same regimens, French subjects had lower baseline PROs but similar or greater post-SVR PRO improvements.

CONCLUSIONS

The use of IFN- and RBV-free regimens leads to significant PRO improvement during treatment and after SVR in French patients with HCV.

Effects of Treatment of Chronic Hepatitis B Virus Infection on Patient-Reported Outcomes

BACKGROUND & AIMS

Chronic infection with hepatitis B virus (HBV) causes liver disease and cirrhosis. It is not clear how treatment of chronic HBV infection affects patient-reported outcomes (PROs). We aimed to assess changes in PROs in patients treated for chronic HBV infection.

METHODS

We collected and analyzed PRO data from 242 patients with chronic HBV infection (without advanced fibrosis or cirrhosis) enrolled in 2 international phase 2 blinded controlled clinical trials from 2015 through 2017. In these trials, patients were treated with an approved oral antiviral regimen (tenofovir, entecavir, adefovir, lamivudine, or telbivudine) and then randomly assigned to groups given vesatolimod (an oral agonist of Toll-like receptor 7) or placebo. PROs were collected using the Short Form-36, the Chronic Liver Disease Questionnaire, and the Work Productivity and Activity Impairment: Specific Health Problem questionnaires before treatment and during treatment weeks 12, 24, and 48.

RESULTS

We did not observe significant differences in PROs between patients receiving vesatolimod vs placebo. At baseline, patients with viral suppression (HBV DNA level, <20 IU/mL) had higher PRO scores (by up to +10.6% of a PRO range size). During treatment, there were significant increases in scores for some domains of the Chronic Liver Disease Questionnaire and in General Health scores of Short Form-36 (increases of up to 4.9%; P < .05). Patients with a decrease of at least 2.7 log₁₀ IU/mL in level of HBV DNA had substantially larger increases in PRO scores (P < .05 for 10 of 22 studied PROs). In multivariate analysis, a reduction in viral load was independently associated with increases in PROs (β values up to 1.6% per log₁₀ IU/mL decrease; P < .05).

CONCLUSIONS

In an analysis of data from phase 2 trials, we associated active treatment of chronic HBV infection with increased PRO scores. These findings support inclusion of PRO end points in assessments of efficacy and safety in clinical trials of treatments for HBV infection.

Health-Related Quality of Life in Chronic HCV-Infected Patients Switching to Pegylated-Interferon-Free Regimens (ANRS CO20 CUPIC Cohort Study and SIRIUS Trial)

OBJECTIVE

We aimed to compare health-related quality of life (HRQL) during and after hepatitis C virus (HCV) treatment in patients receiving pegylated-interferon (PEG-IFN)-containing therapy (including boceprevir or telaprevir-ANRS CO20 CUPIC cohort) who subsequently switched to PEG-IFN-free regimens (sofosbuvir + ledipasvir with or without ribavirin [RBV]-SIRIUS trial).

METHODS

Two analyses were performed. The first compared physical (PCS) and mental (MCS) HRQL (MOS SF-12) scores during treatment between CUPIC and SIRIUS. The second compared PCS and MCS scores after treatment end between CUPIC and SIRIUS. The analyses used linear regression mixed models adjusted for pre-treatment HRQL scores, gender, and age at each visit.

RESULTS

Among patients enrolled successively in both studies, 43 (corresponding to 212 HRQL assessments) and 43 (82 HRQL assessments) were eligible for the 'during' and 'post' treatment analyses, respectively. In the 'during-treatment' analysis, we found significantly higher PCS and MCS values during PEG-IFN-free treatment than for PEG-IFN-containing treatment. In the 'post-treatment' analysis, results showed significantly higher MCS values after PEG-IFN-free treatment than after PEG-IFN-containing treatment. No significant difference was found for PCS in the post-treatment analysis.

CONCLUSIONS

These results highlight an improvement in both physical and mental HRQL during HCV treatment, but no major improvement in physical HRQL after treatment end, when comparing PEG-IFN-free regimens with PEG-IFN-containing regimens. This suggests that in the PEG-IFN-free regimens era, screening and comprehensive care of comorbidities and residual somatic symptoms during treatment, and especially after HCV clearance, are still needed to improve patient outcomes.

Interferon-free therapy in hepatitis C virus (HCV) monoinfected and HCV/HIV coinfected patients: effect on cognitive function, fatigue, and mental health

The efficacy and safety of interferon-free therapies for hepatitis C virus (HCV) infection have been reported. Considering the accumulating evidence for a direct central nervous system infection by HCV, we aim to evaluate the effect of direct acting antivirals (DAA) therapy on cognitive function in HCV patients. We conducted a longitudinal analysis of the cognitive performance of 22 patients (8 HCV+, 14 HCV+/HIV+) who completed neuropsychological testing at baseline and at week 12 after DAA therapy. In 20 patients, we analyzed specific attention parameters derived from an experimental testing based on the Theory of Visual Attention (TVA). Depression, fatigue, and mental health were assessed as patient reported outcomes. At baseline, 54.5% of the patients met the criteria for cognitive impairment and 40% showed impairment in TVA parameters. Follow-up analysis revealed significant improvements in the domains of visual memory/learning, executive functions, verbal fluency, processing speed, and motor skills but not in verbal learning and attention/working memory. We did not observe significant improvement in visual attention measured by TVA. Fatigue and mental health significantly improved at follow-up. Our findings indicate that successful DAA treatment leads to cognitive improvements in several domains measured by standard neuropsychological testing. The absence of improvement in TVA parameters and of significant improvement in the domain of attention/working memory might reflect the persistence of specific cognitive deficits after HCV eradication. In summary, DAA treatment seems to have a positive effect on some cognitive domains and leads to an improvement in mental health and fatigue in HCV-infected patients.

Daclatasvir and asunaprevir improves health-related quality of life in Japanese patients infected with hepatitis C virus

Aims

Interferon-free direct-acting antiviral agent (DAA) regimens for chronic hepatitis C virus (HCV) patients have improved their health-related quality of life (HRQOL). Currently, there are no published data assessing the impact of DAAs regimens without sofosbuvir on HRQOL. The aim of this study was to investigate the improvement of HRQOL in Japanese HCV patients treated with a protease inhibitor and a nonstructural protein 5A inhibitor.

Methods and Results

A total of 123 Japanese genotype 1b HCV patients receiving daclatasvir (DCV) and asunaprevir (ASV) for 24 weeks were enrolled. HRQOL was assessed using the Japanese version of the Chronic Liver Disease Questionnaire (CLDQ) at baseline; weeks 4, 12, and 24; and post-24 weeks. Changes in CLDQ scores were calculated by subtracting the CLDQ score at each time point from the baseline value. Improvement in the mean change of the Japanese version of the CLDQ score became statistically significant as early as week 4 after the initiation of treatment (+9.3%; P < 0.0001) and was sustained during and after DCV/ASV treatment. The changes of CLDQ at posttreatment week 24 in patients with sustained virological responses (SVR) were significantly higher than those in patients without SVR (0.4% and -4.1%, respectively; P < 0.05).

Conclusions

This study of DCV/ASV treatment for Japanese HCV patients in a clinical setting demonstrated that HRQOL can improve as early as at the initiation of treatment and can continue during and after treatment, regardless of the classes of DAAs regimens and race. Moreover, SVR are needed to continue HRQOL improvement.

Patient-Reported Outcomes Following Treatment of Chronic Hepatitis C Virus Infection With Sofosbuvir and Velpatasvir, With or Without Voxilaprevir

BACKGROUND & AIMS

Chronic infection with hepatitis C virus (HCV) has many hepatic and extrahepatic manifestations, measured by patient-reported outcomes (PROs). We measured changes in PROs during HCV treatment with recently developed pangenotypic regimens and from a sustained virologic response 12 weeks after treatment ended (SVR12).

METHODS

We collected PRO data from 2 multi-center, blinded, international phase 3 trials of sofosbuvir, velpatasvir, and voxilaprevir, from 748 patients previously treated with direct-acting antivirals for chronic infection with HCV of any genotype (59% HCV genotype 1, 43% with compensated cirrhosis) (POLARIS-1 and POLARIS-4). The combination of sofosbuvir, velpatasvir, and voxilaprevir was given to 445 patients, the combination of sofosbuvir and velpatasvir to 151 patients, and placebo to 152 patients. Patients completed the SF-36, FACIT-F, CLDQ-HCV, and WPAI:SHP questionnaires at baseline, during treatment, and during the follow-up period.

RESULTS

There was no difference in baseline clinical or demographic features or PRO scores among the groups (all P > .05). The group that received the combination of sofosbuvir, velpatasvir, and voxilaprevir had more gastrointestinal symptoms than the groups that received sofosbuvir and velpatasvir or placebo (P = .0001). An SVR12 was achieved by 90.1% of patients who received sofosbuvir and velpatasvir vs 96.9% of patients who received sofosbuvir, velpatasvir, and voxilaprevir (P = .0008). After 12 weeks of treatment, some PRO scores improved in both treatment groups (by 2.5 or by 9.1 points, on a 0-100 scale; P < .05) but not in the placebo group. All increases in PRO scores were sustained or increased after treatment ended (an increase of up to 11.1 points at 12 weeks after treatment and an increase of up to 16.6 points at 24 weeks after treatment ended) (P < .05 for all but 2 PROs). There were no differences in PROs between the sofosbuvir and velpatasvir group vs the sofosbuvir, velpatasvir, and voxilaprevir group (all P > .05). In multivariate analysis, after adjustment for clinical and demographic factors and baseline PRO scores, receiving treatment was associated with higher PROs scores than receiving placebo (beta as high as 5.1) (P < .05).

CONCLUSIONS

In an analysis of data from 2 phase 3 clinical trials of patients with chronic HCV infection of any genotype, we found the combination of sofosbuvir, velpatasvir, with or without voxilaprevir, to increase PRO scores compared with placebo. These findings indicate the comprehensive benefit of these regimens during treatment and after SVR.

Treatment of early stage chronic hepatitis C virus infection

INTRODUCTION

Treatment of Hepatitis C Virus (HCV) with direct acting antivirals (DAAs) is able to achieve the cure of infection in almost the totality of patients, independently of the characteristics of the individual and the virus, using short treatment schedules, and without the need of ribavirin. The high cost of DAAs is the main limiting factor for universal treatment of HCV. However, there is a strong evidence that treatment of infection at the early stage of disease may be the most rewarding approach. Areas covered: This review evaluates the aspects underlying the benefit of treating chronic HCV infection at the early stage of disease. It outlines the considerations that have to be taken into account when planning treatment in patients with HCV and minimal liver disease, assessing the positive reflex of viral eradication on several HCV-associated extra-hepatic conditions such as the risk of lymphoma, insulin-resistance and glycaemic control, and renal function. Lastly, it also covers the improvement of patients' quality of life and the pharmaco-economic aspects associated with early treatment. Expert commentary: Treatment of patients with HCV and minimal liver disease is associated with a beneficial, pleiotropic effect of viral eradication that goes beyond the simplistic consideration of the improvement in liver disease-related outcomes.

In an era of highly effective treatment, hepatitis C screening of the United States general population should be considered

BACKGROUND & AIMS

Hepatitis C virus (HCV) treatment with all oral direct acting antiviral agents (DAA's) achieve sustained virologic response (SVR) rates of 98%. Re-assessment of general US population screening for HCV is imperative. This study compared the cost-effectiveness (CE) of three HCV screening strategies: screen all (SA), screen Birth Cohort (BCS), and screen high risks (HRS).

METHODS

Using a previous designed decision-analytic Markov model, estimations of the natural history of HCV and CE evaluation of the three HCV screening strategies over a lifetime horizon in the US population was undertaken. Based on age and risk status, 16 cohorts were modelled. Health states included: Fibrosis stages 0 to 4, decompensated cirrhosis, hepatocellular carcinoma, LT, post-LT, and death. The probability of liver disease progression was based on the presence or absence of virus. Treatment was with approved all-oral DAAs; 86% were assumed to be seen annually by a primary care provider; SVR rates, transition probabilities, utilities, and costs were from the literature. One-way sensitivity analyses tested the impact of key model drivers.

RESULTS

SA cost $272.0 billion [$135 279 per patient] and led to 12.19 QALYs per patient. BCS and HRS cost $274.5 billion ($136 568 per patient) and $284.5 billion ($141 502 per patient) with 11.65 and 11.25 QALYs per patient respectively. Compared to BCS, SA led to an additional 0.54 QALYs per patient and saved $2.59 billion; compared to HRS, SA led to 0.95 additional QALYs per patient and saved $12.5 billion.

CONCLUSIONS

Screening the entire US population and treating active viraemia was projected as cost-saving.

Health-related Quality of Life in Adolescent Patients With Hepatitis C Genotype 1 Treated With Sofosbuvir and Ledipasvir

OBJECTIVE

The aim of the study was to assess the effect of treatment with ledipasvir/sofosbuvir (LDV/SOF) on the health-related quality of life (HRQL) of pediatric patients with chronic hepatitis C virus (HCV) infection.

METHODS

Adolescents (12-17 years) with HCV were treated with LDV/SOF (90/400 mg daily) for 12 weeks. HRQL was assessed using the PedsQLv4.0-SF15 completed by the children and caregivers before, during, and after treatment.

RESULTS

We included 100 adolescents with HCV genotype 1 infection (14.7 ± 2.0 years, 1% known cirrhosis, 80% treatment-naïve, 97% sustained virologic response-12). At baseline, HRQL the caregiver- perceived HRQL scores were lower than adolescents' self-reported scores (by 6.7-7.9 points, all P < 0.01). At the end of 12 weeks of treatment, however, the caregiver-reported HRQL scores showed a significant improvement (+all P < 0.04), whereas the adolescents' self-reported scores did not change from the baseline. HRQL scores reported by caregivers remained higher than baseline (by +4.7-+7.5, P < 0.01) through 12 weeks after treatment, as did the adolescents' self-reported Emotional Functioning scores (+4.3 from baseline, P = 0.0009); observed improvements were sustained after 24 weeks of follow-up (all P < 0.04). Multivariate analysis showed that, after adjustment for location, age, and sex, having a history of anxiety and panic disorders were consistent predictors of impaired HRQL in adolescents with HCV infection (P < 0.05).

CONCLUSIONS

Treatment of HCV in adolescents with LDV/SOF is associated with some improvement in HRQL. Caregivers' reports of HRQL in adolescents with HCV significantly increased with treatment and were similar to the adolescent self-reported HRQL after sustained virologic response-12.

Sofosbuvir and velpatasvir with or without voxilaprevir in direct-acting antiviral-naïve chronic hepatitis C: patient-reported outcomes from POLARIS 2 and 3

BACKGROUND

Chronic hepatitis C infection leads to impairment of patient-reported outcomes (PROs). Treatment with direct-acting antiviral regimens results in short- and long-term improvement of these outcomes.

AIM

To assess PROs in patients treated with a newly developed direct-acting antiviral, a fixed-dose combination of sofosbuvir/velpatasvir (SOF/VEL) with/without voxilaprevir (VOX).

METHODS

The PRO data were collected from participants of POLARIS-2 and POLARIS-3 clinical trials (DAA-naïve, all HCV genotypes). Participants self-administered SF-36v2, FACIT-F, CLDQ-HCV and WPAI:SHP instruments at baseline, during treatment, and in follow-up.

RESULTS

Of 1160 patients, 611 received SOF/VEL/VOX and 549 received SOF/VEL (52.8 ± 11.0 years, 55.9% male, 75.4% treatment-naïve, 33.9% cirrhotic). The sustained viral response at 12 weeks (SVR12) rates were 95%-98%. During treatment, improvements in most PRO scores were significant (all but one P < .01) and ranged from, on average, +2.3 to +15.0 points (on a 0-100 scale) by the end of treatment. These improvements were similar between SOF/VEL/VOX and SOF/VEL arms (all P > .05). After treatment discontinuation, patients treated with both regimens achieved significant and clinically meaningful PRO gains (+2.7 to +16.7 by post-treatment week 12, +3.9 to +20.1 by post-treatment week 24; all but one P < .001). Multivariate analysis showed that depression, anxiety and cirrhosis were the most consistent independent predictors of PRO impairment while no association of PROs with the treatment regimen choice was found (all P > .05).

CONCLUSIONS

The pan-genotypic regimens with SOF/VEL with or without VOX not only have excellent efficacy and safety, but also significantly positively impact patients' experience both during treatment and after achieving sustained virologic response in DAA-naïve patients with HCV.

Patient-reported outcomes in patients co-infected with hepatitis C virus and human immunodeficiency virus treated with sofosbuvir and velpatasvir: The ASTRAL-5 study

BACKGROUND & AIM

The fixed-dose combination of sofosbuvir and velpatasvir (SOF/VEL) is a ribavirin-free pan-genotypic regimen with high efficacy. We assessed the impact of SOF/VEL on patient-reported outcomes (PRO) of HIV-HCV co-infected patients.

METHODS

HIV-HCV co-infected patients were treated with 12 weeks of SOF/VEL (400 mg/100 mg daily). All subjects completed four PRO questionnaires [CLDQ-HCV, SF-36, FACIT-F and WPAI:SHP] before, during and post-treatment.

RESULTS

ASTRAL-5 enrolled 106 HIV-HCV co-infected patients on stable antiretroviral therapy (age: 54.2±0.9 years, cirrhosis: 17.9%, HCV genotype 1: 73.6%). SVR-12 was achieved by 95.3% of subjects. By week 4 of treatment, PRO scores improved from the baselines levels in 12 out of 26 calculated PRO domains (on average, +1.9 to +7.4 points on a universal 0-100 PRO scale, all P<.05). By the end of treatment, improvements were seen in 20/26 PRO domains (+2.5% to +11.9%, P<.03). There were no significant decrements in any PRO domains during treatment. By follow-up week 12, patients who achieved SVR-12 experienced significant improvement in 19/26 of their PRO domains (+3.2% to +13.3%, P<.05). After controlling for baseline psychiatric co-morbidities, improvements in PRO scores during treatment with SOF/VEL were similar to those seen in matched HCV-mono-infected patients treated with the same regimen (ASTRAL-1 study). In multivariate analysis, pre-treatment anxiety and concomitant use of opioids were the most consistent significant (P<.05) predictors of PRO impairment in HIV-HCV patients.

CONCLUSIONS

Patients with HIV-HCV treated with SOF/VEL experience very high efficacy accompanied by early and sustained improvement of patient-reported outcomes covering all aspects of patients' experience.

Current and future challenges in HCV: insights from an Italian experts panel

BACKGROUND

The recent availability of direct acting antiviral drugs (DAAs) has drastically changed hepatitis C virus (HCV) treatment scenarios, due to the exceedingly high rates of sustained virological response (SVR) and excellent tolerability allowing for treatment at all disease stages.

METHODS

A panel of Italian experts was convened twice, in November 2016 and January 2017, to provide further support on some open issues and provide guidance for personalized HCV care, also in light of forthcoming regimens.

RESULTS AND CONCLUSIONS

Treatment recommendations issued by international and national liver societies to guide clinicians in the management of HCV infection are constantly updated due to accumulating new data. Such recommendations may not be applicable to all healthcare settings for a variety of reasons. Moreover, some gaps still remain and the spectrum of patients to be treated is also evolving.

Chronic Hepatitis C Virus Infection and Depression

Hepatitis C virus (HCV) infection is a systemic disease with hepatic and extrahepatic manifestations, including neuropsychiatric conditions. Depression is a frequent disorder, which has been reported in one-third of patients with HCV infection and has an estimated prevalence of 1.5 to 4.0 times higher than that observed in patients with chronic hepatitis B virus infection or the general population. HCV seems to play a direct and indirect role in the development of depression. Impaired quality of life and increasing health care costs have been reported for patients with HCV infection with depression. Treatment-induced HCV clearance has been associated with improvement of depression and quality of life.

Patient-Reported Outcomes and Fatigue in Patients with Chronic Hepatitis C Infection

Fatigue is a common symptom. Diagnosis is difficult. Fatigue is often a complex symptom. In the recent years, fatigue has gained considerable amount of attention. It has 2 major types, central and peripheral, which may occur together or alone. Although fatigue has many strong relations with depression and sleep disorders, it is a separate entity. For the diagnosis of fatigue, self-reports and patient-reported outcomes are highly valuable tools because these methods can reflect patients' perceptions. Treating the underlying disease with newly developed direct-acting antivirals often improves the perceived fatigue. Healthy lifestyle changes are the cornerstone of the treatment.

Hepatitis C virus infection

Hepatitis C virus (HCV) is a hepatotropic RNA virus that causes progressive liver damage, which might result in liver cirrhosis and hepatocellular carcinoma. Globally, between 64 and 103 million people are chronically infected. Major risk factors for this blood-borne virus infection are unsafe injection drug use and unsterile medical procedures (iatrogenic infections) in countries with high HCV prevalence. Diagnostic procedures include serum HCV antibody testing, HCV RNA measurement, viral genotype and subtype determination and, lately, assessment of resistance-associated substitutions. Various direct-acting antiviral agents (DAAs) have become available, which target three proteins involved in crucial steps of the HCV life cycle: the NS3/4A protease, the NS5A protein and the RNA-dependent RNA polymerase NS5B protein. Combination of two or three of these DAAs can cure (defined as a sustained virological response 12 weeks after treatment) HCV infection in >90% of patients, including populations that have been difficult to treat in the past. As long as a prophylactic vaccine is not available, the HCV pandemic has to be controlled by treatment-as-prevention strategies, effective screening programmes and global access to treatment.

The levels of monoamine neurotransmitters and measures of mental and emotional health in HCV patients treated with ledipasvir (LDV) and sofosbuvir (SOF) with or without ribavirin (RBV)

Mental and emotional health (MEH) impairment is commonly encountered in hepatitis C patients. Although the exact mechanism remains unknown, alterations in neurotransmitter and cytokine levels maybe associated with hepatitis C virus (HCV)-related MEH issues.The aim of the study was to assess association of serum biomarkers with self-reports of MEH in HCV patients before treatment and after achieving sustained virologic response (SVR).The HCV genotype-1-infected patients who achieved SVR at 12 weeks after treatment with ledipasvir (LDV)/sofosbuvir (SOF) ± ribavirin (RBV) were selected. Frozen serum samples from baseline, end of treatment (EOT), and posttreatment week 4 (PTW4) were used to assay 16 cytokines and monoamine neurotransmitters. Validated self-reports were used to assess MEH.Hundred patients were evaluated. Mean age was 53 years (57% male, 86% white). Compared with baseline, emotional well-being and emotional health significantly increased by EOT, and role emotional, emotional well-being, and emotional health significantly increased at PTW4 in the RBV-containing arm (P < 0.05). In patients taking LDV/SOF + RBV, serotonin levels were significantly decreased at PTW4 compared with baseline (P = 0.046). Compared with baseline, there were significant decreases in interleukin (IL)-10 levels at EOT and PTW4 in both treatment groups. The changes in IL-8 also differed significantly between LDV/SOF + RBV and LDV/SOF groups (P < 0.05). Changes in dopamine and tryptophan levels at EOT correlated with increasing emotional health scores, whereas changes in monocyte chemoattractant protein-1 at EOT and IL-8 at PTW4 correlated with increasing mental health scores. The neurotransmitters and cytokines were found to be independent predictors of MEH scores in multiple regression analysis.Cytokine and neurotransmitter changes are associated with mental and emotional health. Patient-reported outcome scores change during and after treatment.

Hepatitis C infection: A multi-faceted systemic disease with clinical, patient reported and economic consequences

Hepatitis C virus infection (HCV) affects approximately 170-200 million individuals globally. HCV is one of the primary causes of hepatocellular carcinoma (HCC) and cirrhosis and has been identified as the leading indication for liver transplantation in most Western countries. Because HCV is a systemic disease with hepatic, extrahepatic, economic and patient reported consequences, it is important for healthcare practitioners to understand the comprehensive and multi-faceted picture of this disease. In this context, it is important to fully appreciate the impact of HCV on the individual patient and the society. With the recent advent of the new generation of direct antiviral agents, the long standing goal of eradicating HCV in most infected patients has been accomplished. Therefore, now more than ever, it is critical to assess the total benefits of sustained virological response in a comprehensive manner. This should not be limited to the clinical benefits of HCV cure, but also to account for the improvement of patient reported health and economic outcomes of HCV cure. It is only through this comprehensive approach to HCV and its treatment that we will understand the full impact of this disease and the tremendous gains that have been achieved with the new antiviral regimens.

IL-6 serum levels are elevated in Parkinson's disease patients with fatigue compared to patients without fatigue

To investigate the influence of interleukin-6 (IL-6) and soluble tumor necrosis factor receptors (sTNFR) in fatigued Parkinson's disease (PD) patients. Forty-four PD patients were evaluated, and fatigue was assessed with the Parkinson Fatigue Scale. Logistic regression analysis was used to evaluate the contribution of disease severity scores and cytokine levels on fatigue scores. A receiver operating characteristic (ROC) curve was used to evaluate the diagnostic values of IL-6 in fatigue. Fatigued PD patients had worse cognitive function and depressive symptoms. These patients had worse PD signs and symptoms, displayed more advanced stages of PD, and had greater functional dependence. There was a significant difference in IL-6 serum levels (p=0.026), but there was no difference in sTNFR levels. Total scores on the Unified Parkinson Disease Rating Scale (β=1.108; p=0.004) and IL-6 levels (β=12.843; p=0.020) were found to be significant predictors of fatigue scores. A ROC curve revealed that IL-6 concentrations of 1.18pg/ml represented the best cut-off value for detecting fatigue (sensitivity of 0.941 and specificity of 0.704). Fatigued PD patients have poor clinical outcomes and elevated IL-6 serum levels when compared with non-fatigued patients. These results suggest that IL-6 may play a role in the pathophysiology of fatigue in PD.

Short article: Fatigue in the long term after HCV treatment in HIV-HCV-coinfected patients: functional limitations persist despite viral clearance in patients exposed to peg-interferon/ribavirin-containing regimens (ANRS CO13-HEPAVIH cohort)

OBJECTIVES

To analyze the impact of fatigue on individuals' global, cognitive, physical, and psychosocial functioning in the long term after hepatitis C virus (HCV) treatment and its relationship with HCV clearance among patients coinfected with HIV and HCV exposed to peg-interferon/ribavirin-containing regimens.

PATIENTS AND METHODS

The study sample included 107 coinfected patients treated for HCV during follow-up in the French ANRS CO13-HEPAVIH cohort. Analyses used scores from the Fatigue Impact Scale (FIS), assessed before treatment initiation and at last available measure after the end of treatment (2 years in median). Patient proportions with a clinically significant improvement in fatigue impact, defined as a decrease higher than 10 points in the 160-point global FIS score, were compared between HCV clearers and chronic HCV patients (Fisher's exact test). Relationships between HCV clearance and FIS scores were analyzed in linear regression models adjusted for sex, time since end of HCV treatment, and pretreatment scores.

RESULTS

Twenty-nine percent of patients showed a clinically significant improvement in fatigue (15/57 in HCV clearers vs. 16/50 in chronic HCV patients, P=0.52). HCV clearance was not significantly associated with FIS scores in multivariate models.

CONCLUSION

The role of HCV clearance in coinfected patients' functional recovery in the long term after peg-interferon/ribavirin treatment may be lesser than expected. Additional studies are needed in patients treated with direct-acting antiviral agents. In the meantime, the effectiveness of palliative care and targeted psychological treatments such as cognitive-behavioral therapy in reducing fatigue impact needs to be assessed in the many HCV-cured patients with HIV exposed to suboptimal interferon-based first-generation therapies.

Patient-reported outcomes with sofosbuvir and velpatasvir with or without ribavirin for hepatitis C virus-related decompensated cirrhosis: an exploratory analysis from the randomised, open-label ASTRAL-4 phase 3 trial

BACKGROUND

Hepatitis C virus (HCV) treatment regimens with direct-acting antivirals have not been extensively studied in patients with decompensated cirrhosis. We assessed patient-reported outcomes (PROs) in patients with decompensated cirrhosis given a fixed-dose combination of sofosbuvir and velpatasvir with and without ribavirin.

METHODS

This study was an exploratory analysis of data collected in a randomised, open-label phase 3 trial (ASTRAL-4) in which patients with HCV-related decompensated cirrhosis were randomly assigned to an all-oral fixed-dose combination of sofosbuvir (400 mg) and velpatasvir (100 mg) once daily for 12 weeks, sofosbuvir and velpatasvir plus oral ribavirin (weight-based 1000 mg or 1200 mg) for 12 weeks, or sofosbuvir and velpatasvir for 24 weeks. Eligible patients were aged 18 years or older with any HCV genotype and decompensated cirrhosis at screening. PROs were collected for the intention-to-treat population using four questionnaires, Short Form (36) Health Survey version 2 (SF-36v2), the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F), the Chronic Liver Disease Questionnaire-HCV Version (CLDQ-HCV), and the Work Productivity Activity Index:HCV (WPAI), which were given prospectively to patients before, during, and after treatment. The ASTRAL-4 study is registered with ClinicalTrials.gov, number NCT02201901.

FINDINGS

Patients were enrolled at 47 hepatology outpatient practices in the USA from Aug 19, 2014, to Dec 19, 2014. 267 patients with HCV-related decompensated cirrhosis were included. In patients given sofosbuvir and velpatasvir for 12 weeks (n=90), clinically significant improvements in PROs started 4 weeks after treatment initiation (+4·4 to +7·5 points on a 0-100 scale at treatment week 4). By the end of treatment, mean improvements in PROs of +5·3 to +16·0 points were noted in all PROs except for role emotional, mental component summary, and social wellbeing scores and work productivity metrics by WPAI:HCV. Similar end-of-treatment improvements (+3·8 to +17·0 points) were observed in patients given sofosbuvir and velpatasvir for 24 weeks (n=90). In patients given sofosbuvir and velpatasvir plus ribavirin (n=87), PRO scores decreased within 4 weeks of treatment (-3·6 to -6·9 points), although scores returned to the baseline levels by the end of treatment. After treatment cessation, significant improvements in all PROs were similar between the treatment groups (all p>0·01) and, by post-treatment week 24, improvements were between +4·9 and +21·2 points. In multivariate analysis, predictors of PRO impairment were treatment naivety, anxiety, use of anxiolytics, use of antidepressants, use of opioids, ribavirin use, the presence of ascites, encephalopathy, insomnia, and depression.

INTERPRETATION

A clinically significant early (within 4 weeks) and sustained improvement in PROs was observed in patients with HCV-related decompensated cirrhosis who were given sofosbuvir and velpatasvir without ribavirin. A similar regimen with ribavirin resulted in a temporary decrease in PROs, which completely resolved after 8 weeks of treatment. Accompanied by high efficacy, the favourable effect of treatment on PROs improves patients' experience in this difficult-to-treat population with HCV.

Quality of life of Japanese patients with chronic hepatitis C treated with ledipasvir and sofosbuvir

The interferon (IFN)-free regimens for chronic hepatitis C (CHC) have high efficacy and superior health-related quality of life (HRQOL) in European/North American patients. The impact of these regimens on HRQOL of the Japanese CHC patients is not known.The Short Form-36 was administered before, during, and after treatment to CHC patients with genotype 1 treated with ledipasvir/sofosbuvir ± ribavirin (LDV/SOF ± RBV) for 12 weeks and genotype 2 treated with SOF + RBV for 12 weeks in clinical trials. The HRQOL data were analyzed with reference to treatment regimens and clinical factors.A total of 494 CHC patients were included (19% cirrhotic, 69% genotype 1, 52% treatment-naive; 153 received SOF + RBV, 170 received LDV/SOF + RBV, 171 received LDV/SOF). The sustained virologic response-12 rates for these regimens were 97%, 98%, and 100%, respectively. CHC patients treated with LDV/SOF, SOF + RBV, or LDV/SOF + RBV regimens had similar HRQOL scores at baseline. During treatment, more adverse events were experienced by those treated with RBV-containing regimens (46% vs 22%, P < 0.0001). The decrements in HRQOL were also significant in RBV groups: up to -3.8 points (treatment week-4), -5.2 (treatment week-12), and -3.2 (posttreatment week-12) (all P < 0.001). In contrast, RBV-free regimen (LDV/SOF) was associated with an improvement in HRQOL up to +4.1 points throughout the treatment (P < 0.01). In multivariate analysis, the use of RBV was independently associated with lower HRQOL during and after treatment (beta up to -6.4 points, P = 0.0001).Japanese CHC patients treated with RBV-containing regimens show mild HRQOL impairment. In contrast, patients treated with LDV/SOF not only showed high efficacy but also improvement of HRQOL.

Ribavirin-Free Regimen With Sofosbuvir and Velpatasvir Is Associated With High Efficacy and Improvement of Patient-Reported Outcomes in Patients With Genotypes 2 and 3 Chronic Hepatitis C: Results From Astral-2 and -3 Clinical Trials

BACKGROUND

Until recently, the approved treatment regimens for patients with hepatitis C virus (HCV) genotypes (GTs) 2 and 3 contain sofosbuvir (SOF) and ribavirin (RBV) for 12 or 24 weeks. The impact of RBV-free pan-genotypic regimen with SOF and velpatasvir (SOF/VEL) on patient-reported outcomes (PROs) of patients with genotype 2 and 3 has not been described.

METHODS

PROs data were collected from participants of ASTRAL-2 and ASTRAL-3 studies before, during, and after treatment using 4 PRO instruments (Short Form-36, Chronic Liver Disease Questionnaire-HCV, Functional Assessment of Chronic Illness Therapy-Fatigue, and Work Productivity and Activity Index: Specific Health Problem), and compared between the SOF/VEL and SOF + RBV groups.

RESULTS

A total of 818 HCV patients were included: 78% treatment naive, 25% cirrhosis. The rates of nearly all adverse events were lower in the RBV-free SOF/VEL group (all P < .03). The SOF/VEL group also experienced improvement of their PROs by treatment week 4 (+1.8% on average across all PROs), which continued throughout treatment (+4.1%) and post-treatment (+5.5%). In contrast, those in the SOF + RBV group had a modest decline in their PROs starting at treatment week 4 (up to -3.7%), which lasted until the end of treatment (up to -6.4%). In multiple regression analysis, the association of a treatment regimen with end-of-treatment PROs was significant for nearly all PROs; the average beta was +5.0% for the use of SOF/VEL (reference: SOF + RBV).

CONCLUSIONS

Patients receiving ribavirin-free SOF/VEL reported significantly better PRO scores during treatment compared with those receiving the RBV-containing regimen. Furthermore, the interferon- and ribavirin-free SOF/VEL regimen resulted in a rapid improvement of PROs in HCV GTs 2 and 3 patients during treatment and after achieving sustained virologic response.

Interferon-free regimens improve health-related quality of life and fatigue in HIV/HCV-coinfected patients with advanced liver disease: A retrospective study

Health-related quality of life (HRQoL) is impaired in HIV/HCV-coinfected patients (HIV/HCV) and further decreased by interferon (IFN)-based therapies. We aimed to investigate the impact of IFN- and ribavirin (RBV)-free therapies on HRQoL and fatigue.Thirty-three HIV/HCV-coinfected patients who underwent HCV therapy with sofosbuvir in combination with daclatasvir or ledipasvir were retrospectively studied and compared to 17 patients who received boceprevir (BOC)/PEGIFN/RBV. HRQoL (mental [MCS] and physical [PCS] component score) and fatigue were assessed using the SF-36 (Short Form 36 Health Survey) and the FSS (Fatigue Severity Scale), respectively. HRQoL/fatigue was evaluated at baseline (BL), midway, and 12 weeks after the end of treatment (FU).At BL, both domains of HRQoL as well as the severity of fatigue were significantly impaired in HIV/HCV, when compared to a healthy population. Already during treatment, IFN/RBV-free therapy improved physical health (PCS: 41.4 ± 9.7 vs. 47.0 ± 11.2; P < 0.01) and reduced fatigue (37.8 ± 14.0 vs. 31.9 ± 15.2; P = 0.01), whereas we observed a substantial worsening of both factors in patients treated with BOC/PEGIFN/RBV. Since these improvements were maintained, patients treated with IFN/RBV-free therapy reported an improvement in physical health (PCS: 41.4 ± 9.7 vs. 45.8 ± 12.7; P < 0.01) and fatigue (37.8 ± 14.0 vs. 30.9 ± 14.8; P = 0.04) at FU. While AIDS-patients had a higher severity of fatigue at BL and showed a reduction of fatigue (42.5 ± 14.0 vs. 31.6 ± 15.7; P = 0.01), mental health only improved in patients without AIDS (MCS: 35.7 ± 5.3 vs.40.7 ± 6.4; P = 0.04). HIV/HCV with severe fatigue at BL (>median BL-FSS) showed most pronounced improvements in severity of fatigue (49.7 ± 7.0 vs. 32.0 ± 16.7; P < 0.01).In contrast to IFN-based regimens, highly effective and well-tolerated IFN-/RBV-free regimens improve HRQoL (especially physical health) and fatigue already during treatment. All patients with HIV/HCV coinfection should be considered for HCV treatment; however, patients with severe fatigue should be prioritized.

Sofosbuvir/velpatasvir improves patient-reported outcomes in HCV patients: Results from ASTRAL-1 placebo-controlled trial

BACKGROUND & AIMS

The new pan-genotypic regimen [sofosbuvir (SOF) and velpatasvir (VEL)] for hepatitis C virus (HCV) has been associated with high efficacy. The aim of this study was to assess patient-reported outcomes (PROs) of this regimen.

METHODS

The PRO data (CLDQ-HCV, SF-36, FACIT-F, WPAI) came from the ASTRAL-1 study, a multicenter multinational blinded placebo-controlled phase 3 clinical trial of a fixed dose combination of SOF 400mg and VEL 100mg for patients with genotype 1, 2, 4, 5, and 6 compared to placebo for 12weeks.

RESULTS

624 patients received active treatment [618 achieved sustained virologic response (SVR)], and 116 received placebo. The baseline PRO scores were similar. By treatment week 4, patients receiving SOF/VEL experienced improvements in general health (on average, +2.3points), emotional well-being (+3.4), FACIT-F (+1.3), and all domains of CLDQ-HCV (+2.1 to +7.3) (all p<0.005). On the other hand, the only PRO that improved in patients receiving placebo was the worry domain of CLDQ-HCV: +4.6 (p=0.002). By the end of treatment, improvement in PRO scores with SOF/VEL continued, and no improvement was noted in the placebo. Improvement in PROs were also noted 12 and 24weeks post-treatment: +3.7, on average, in patients with SVR-12 after SOF/VEL vs. -2.6, on average, in the placebo arm (p<0.005). Multivariate analysis showed that treatment-emergent changes in PROs were predicted by receiving SOF/VEL for some summary PRO score (p<0.005).

CONCLUSIONS

This placebo-controlled trial shows that patients treated with SOF/VEL experience significant improvement of their PROs during treatment and after achieving SVR.

LAY SUMMARY

In patients with chronic hepatitis C infection, health-related quality of life and work productivity are often impaired due to HCV-related fatigue. Treatment of hepatitis C with interferon-based regimens, which was the standard of care for all HCV patients until recently, had substantial and potentially debilitating side effects. These regimens caused additional impairment in health-related quality of life and work productivity during treatment and shortly after treatment cessation. The newly developed interferon-free combination of sofosbuvir and velpatasvir has been shown to improve health-related quality of life during treatment, and lead to an improvement in a number of indicators of patient-reported outcomes after successful clearance of HCV and achieving sustained virologic response.

Hepatitis C virus as a systemic disease: reaching beyond the liver

Chronic hepatitis C (CHC) is associated with multiple extrahepatic manifestations that may impact infected patients. The mechanisms through which these develop include those which are immunological, in which the chronic persistence of virus leads to the circulation of immune complexes (mixed cryoglobulinemia) and other autoimmune phenomena, and those which are virological and related to the extrahepatic tropism of the virus to other tissues. It is estimated that 40-74 % of patients with CHC may develop at least one extrahepatic manifestation during the course of the disease. Extrahepatic syndromes may represent the first signal of hepatitis C infection in some patients. CHC is associated with a four-fold increased risk of insulin resistance and type 2 diabetes mellitus; with cardiovascular disease in 17-37 % of patients; and with increased risk for cerebrovascular deaths, with a biological gradient of cerebrovascular mortality correlating with an increasing serum viral load. CHC is also associated with lymphoproliferative disorders, particularly non-Hodgkin B-cell lymphoma. The kidney is involved in 35-60 % of patients with CHC-associated mixed cryoglobulinemia. The prevalent type of glomerulonephritis associated with mixed cryoglobulinemia is membranoproliferative glomerulonephritis. In 30 % of cases, renal involvement begins with a nephritis syndrome and acute renal failure, while in 55 % there is only mild hematuria, microalbuminuria, proteinuria and renal insufficiency. CHC is also associated with cognitive impairment, especially in memory and concentration. Thus, extrahepatic CHC manifestations involve multiple organ systems outside the liver linked to a variety of comorbidities which may lead to significantly increased mortality from non-liver-related events.
