Abstract
Hepatitis C virus (HCV) infection is a major health problem worldwide. It can cause liver cirrhosis and hepatocellular carcinoma (HCC), making it a cause of morbidity from liver disease. Thus, there is an urgent need for a prophylactic HCV vaccine. Fortunately, modern medicine has transformed the therapy for HCV infection through development of direct-acting antiviral agents (DAAs), achieving high rates of sustained virologic response and giving significant relief from HCC and associated mortality, but unfortunately it fails to eradicate the risk of HCC, especially in HCV-cleared patients with already advanced liver disease. Additionally, DAA-cured patients do not develop sufficient antiviral immunity and are susceptible to reinfection. A comprehensive strategy to control HCV infection must include a vaccine development approach in which the host can develop humoral and cellular immunity to eradicate HCV successfully; however, this remains a challenge as HCV has developed systems to evade immune attacks from its host. This review highlights the current understanding of HCV's effect on liver disease and cancer progression, the nature of immune responses from cell populations interacting with HCV, and the current strategies for vaccine development. The information in this review will advance prophylactic intervention strategies for HCV infection, with the end goal being to prevent chronicity and subsequent liver disease leading to HCC.

Phase 1 study of safety and tolerability of an oral contraceptive containing low-dose ethinyl oestradiol combined with glecaprevir/pibrentasvir treatment in healthy premenopausal women. J Viral Hepat 2024; 31:409-415. [PMID: 38654438 DOI: 10.1111/jvh.13946] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/01/2024] [Revised: 04/09/2024] [Accepted: 04/13/2024] [Indexed: 04/26/2024]
Abstract
Glecaprevir/pibrentasvir (GLE/PIB) is an approved guideline-recommended chronic hepatitis C virus infection treatment. GLE/PIB coadministration with ethinyl oestradiol (EE) is not recommended in current labels owing to a Phase 1 study observing Grade ≥2 alanine aminotransferase (ALT) elevation in 2 out of 12 healthy women cotreated for 11 days with GLE/PIB and oral contraceptive (OC) containing 35 μg/250 μg EE/norgestimate. No Grade ≥2 elevation was observed with low-dose (20 μg) EE (n = 14). This Phase 1 study examined safety/tolerability of GLE/PIB coadministered with an OC containing low-dose EE using a larger sample size and longer treatment duration. Healthy premenopausal women were treated with EE/levonorgestrel alone (20/100 μg, Cycles 1-2), followed by coadministration with GLE/PIB (300/120 mg; Cycles 3-4). A safety criterion of special interest was a confirmed Grade ≥2 ALT elevation (>3× upper normal limit). Adverse events (AEs) and study drugs concentrations were examined. Of 85 enrolled women, 72 initiated combined GLE/PIB + EE/levonorgestrel treatment, 66 completed the study and 19 discontinued prematurely (non-safety reason, n = 16; AE [deemed unelated to GLE/PIB], n = 3). No participant met the safety criterion of special interest of confirmed Grade ≥2 ALT elevation. No serious/Grade ≥3 AEs were reported. Study drug concentrations were within the expected ranges. GLE/PIB in combination with an OC containing low-dose EE was generally well tolerated with no confirmed Grade ≥2 ALT elevation and no evidence of drug-induced liver injury. No pattern to the reported AEs and no new safety issues were identified. This was a Phase 1 study of healthy volunteers, not a registered clinical trial.

Abstract
BACKGROUND The treatment of chronic hepatitis C virus (HCV) infection using directly acting antivirals was recently adopted in the treatment guidelines of Zimbabwe. The objectives of this study were to design a simplified model of HCV care and estimate the cost of screening and treatment of hepatitis C infection at a tertiary hospital in Zimbabwe. METHODS We developed a model of care for HCV using WHO 2018 guidelines for the treatment of HCV infection and expert opinion. We then performed a micro-costing to estimate the costs of implementing the model of care from the healthcare sector perspective. Deterministic and probabilistic sensitivity analyses were performed to explore the impact of uncertainty in input parameters on the estimated total cost of care. RESULTS The total cost of screening and treatment was estimated to be US$2448 (SD=$290) per patient over a 12-week treatment duration using sofosbuvir/velpatasvir. The cost of directly acting antivirals contributed 57.5% to the total cost of care. The second largest cost driver was the cost of diagnosis, US$819, contributing 34.6% to the total cost of care. CONCLUSION Screening and treatment of HCV-infected individuals using directly acting antivirals at a tertiary hospital in Zimbabwe may require substantial financial resources.

Abstract
Hepatitis C virus (HCV) remains a significant global health challenge. Approximately 50 million people were living with chronic hepatitis C based on the World Health Organization as of 2024, contributing extensively to global morbidity and mortality. The advent and approval of several direct-acting antiviral (DAA) regimens significantly improved HCV treatment, offering potentially high rates of cure for chronic hepatitis C. However, the promising aim of eventual HCV eradication remains challenging. Key challenges include the variability in DAA access across different regions, slightly variable response rates to DAAs across diverse patient populations and HCV genotypes/subtypes, and the emergence of resistance-associated substitutions (RASs), potentially conferring resistance to DAAs. Therefore, periodic reassessment of current HCV knowledge is needed. An up-to-date review on HCV is also necessitated based on the observed shifts in HCV epidemiological trends, continuous development and approval of therapeutic strategies, and changes in public health policies. Thus, the current comprehensive review aimed to integrate the latest knowledge on the epidemiology, pathophysiology, diagnostic approaches, treatment options and preventive strategies for HCV, with a particular focus on the current challenges associated with RASs and ongoing efforts in vaccine development. This review sought to provide healthcare professionals, researchers, and policymakers with the necessary insights to address the HCV burden more effectively. We aimed to highlight the progress made in managing and preventing HCV infection and to highlight the persistent barriers challenging the prevention of HCV infection. The overarching goal was to align with global health objectives towards reducing the burden of chronic hepatitis, aiming for its eventual elimination as a public health threat by 2030.

[PMID: 38792479 PMCID: PMC11121813 DOI: 10.3390/jcm13102939] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2024] [Revised: 05/10/2024] [Accepted: 05/14/2024] [Indexed: 05/26/2024] Open
Abstract
Background: Chronic hepatitis C (HCV) infection presents global health challenges with significant morbidity and mortality implications. Successfully treating patients with cirrhosis may lead to mortality rates comparable to the general population. This study aims to utilize machine learning techniques to create predictive mortality models for individuals with chronic HCV infections. Methods: Data from chronic HCV patients at Sultan Qaboos University Hospital (2009-2017) underwent analysis. Data pre-processing handled missing values and scaled features using Python via Anaconda. Model training involved SelectKBest feature selection and algorithms such as logistic regression, random forest, gradient boosting, and SVM. The evaluation included diverse metrics, with 5-fold cross-validation, ensuring consistent performance assessment. Results: A cohort of 702 patients meeting the eligibility criteria, predominantly male, with a median age of 47, was analyzed across a follow-up period of 97.4 months. Survival probabilities at 12, 36, and 120 months were 90.0%, 84.0%, and 73.0%, respectively. Ten key features selected for mortality prediction included hemoglobin levels, alanine aminotransferase, comorbidities, HCV genotype, coinfections, follow-up duration, and treatment response. Machine learning models, including the logistic regression, random forest, gradient boosting, and support vector machine models, showed high discriminatory power, with logistic regression consistently achieving an AUC value of 0.929. Factors associated with increased mortality risk included cardiovascular diseases, coinfections, and failure to achieve a SVR, while lower ALT levels and specific HCV genotypes were linked to better survival outcomes. Conclusions: This study presents the use of machine learning models to predict mortality in chronic HCV patients, providing crucial insights for risk assessment and tailored treatments. Further validation and refinement of these models are essential to enhance their clinical utility, optimize patient care, and improve outcomes for individuals with chronic HCV infections.

Abstract
BACKGROUND In France, migrants constitute a significant proportion of people diagnosed with HIV, hepatitis C (HCV) and B (HBV). This study estimated the prevalence of these three viruses among detainees at a French administrative detention centre (CRA), through systematic Rapid Diagnostic Test (RDT) screening. METHODS This prospective, single-centre, cross-sectional, pilot study included detainees at the Nîmes CRA from February to December 2022. The primary endpoint was HIV, HCV and HBV prevalence determined by RDT. Secondary outcomes were: co-infections; study acceptability, reasons for non-inclusion, causes of non-contributory samples; and concordance between serological tests and RDT. RESULTS Among the 350 people agreeing to participate of 726 eligible, five refused the RDT, leaving 345 analysable participants for a participation rate of 47.5% (345/726). Participants were predominantly male (90%) with an average age of 31 years. The most common country of origin was Algeria (34%). Twenty (6%) had taken drugs intravenously and 240 (70%) had had unprotected sex within a median of 4.92 [1.08; 15] months. Virus prevalence was: 0% HIV; 4.64 [2.42; 6.86] % HCV; and 2.32 [1.01; 4.52] % HBV. Eleven (73%) of the RDT HCV positive cases were confirmed serologically. RDT detected one false-positive HCV case, as an anti-HCV Ac serological test was negative. Of the eight patients with positive HBV RDT, one declined the serology testing, thus 100% (7/7) of the tested RDT positive cases were confirmed by serology. CONCLUSION The study highlighted the need to screen detainees for HIV, HCV and HBV infection and suitability of RDTs.

Abstract
Persistent viruses are hard to be eradicated, even using effective medications, and can persist for a long time in humans, sometimes regardless of treatment. Hepatitis B virus, hepatitis C virus, human immunodeficiency virus, and human T cell lymphotropic virus infections, the most common in our era, are still a challenge despite the increased knowledge about their biology. Most of them are highly pathogenic, some causing acute disease or, more often, leading to chronic persistent infections, and some of the occult, carrying a high risk of morbidity and mortality. However, if such infections were discovered early, they might be eradicated in the near future with effective medications and/or vaccines. This perspective review points out some specific characteristics of the most important chronic persistent viruses. It seems that in the next few years, these persistent viruses may have control by vaccination, epidemiological strategies, and/or treatment.

Abstract
BACKGROUND To establish a chemiluminescence method for detecting anti-E1 and anti-E2 antibodies in the serum of patients with hepatitis C virus (HCV) infection. METHODS The microplate was coated with recombinant envelope proteins E1 and E2 by indirect method, respectively, and the kits for detecting anti-E1 and anti-E2 antibodies were prepared. The methodological indexes were evaluated. RESULTS The methodological indexes of the kits were as follows: precision test (the variation coefficient of anti-E1 antibody 6.71%-8.95% for within run and 9.91%-12.16% for between run, the variation coefficient of anti-E2 antibody 6.06%-8.44% for within run and 10.77%-13.98% for between run, respectively). The blank limit and detection limit were 1.18 RLIR and 3.16 RLIR for the anti-E1 antibody, and 1.26 RLIR and 3.32 RLIR for the anti-E2 antibody, respectively. The correlation coefficients (r) of anti-E1 and anti-E2 were 0.9963 and 0.9828, the analysis and measurement ranges (AMR) were 1.66-41.28 RLIR and 1.55-19.46 RLIR, and the average recovery was 96.4% and 93.7%, respectively. The rheumatoid factor and other positive serum samples had no interference or cross-reaction to the test, and the kits were stable within 15 months. The positive rates of anti-E1 and anti-E2 antibodies in 45 patients with HCV infection were 35.6% (16/45) and 44.4% (20/45), respectively. CONCLUSIONS The kits for detecting anti-E1 and anti-E2 meet the requirements of methodology, and can be used in screening diagnosis, disease monitoring, prognosis evaluation, disease mechanism, and epidemiological studies of HCV infection. The HCV envelope proteins E1 and E2 have an immune response in HCV-infected patients.

Abstract
Therapeutic innovation is expected to change if not disrupt present care models for several chronic diseases in the coming years, as suggested by recent clinical trials. New drugs that anticipate and possibly delay the full expression of a disease will likely face some common challenges, such as the need of designing and implementing large scale interventions; the necessary engagement of multiple specialties for both diagnosis and treatment; the shift from specialist to non-specialist interventions and secondary prevention. Building on the case of HCV and other innovation in hepatology, we discuss common challenges caused by disruptive change that other chronic conditions faced in the past. The recent history of hepatology shows interesting examples of disruptive innovations that completely reverted traditional treatment approaches. As we learned from the slow early diffusion of antiviral drugs, without a clear information and a prompt design of the appropriate delivery modalities, the effectiveness of new treatments is undermined and care risk to be postponed for long time. This implies the definition of (i) new service models diversified by care phases and patients' target; (ii) horizontal integration: to go beyond the professional boundaries to build solid alliances; (iii) vertical integration between primary and secondary care.

Abstract
BACKGROUND AND AIMS Treatment for chronic hepatitis C virus (HCV) infections changed dramatically in the last decade. We assessed changes in the prevalence of replicating HCV infection, treatment uptake and liver-related morbidity and mortality in persons with HIV (PWH) and hepatitis C in the Swiss HIV cohort study. METHODS We included all cohort participants between 2002 and 2021. We assessed yearly prevalence of replicating HCV infection, overall and liver-related mortality, as well as the yearly incidence of liver-related events in persons with at least one documented positive HCV-RNA. RESULTS Of 14 652 participants under follow-up, 2294 had at least one positive HCV-RNA measurement. Of those, 1316 (57%) ever received an HCV treatment. Treatment uptake increased from 8.1% in 2002 to a maximum of 32.6% in 2016. Overall, prevalence of replicating HCV infection declined from 16.5% in 2004 to 1.3% in 2021. HCV prevalence declined from 63.2% to 7.1% in persons who inject drugs, and from 4.1% to 0.6% in men who have sex with men. Among the 2294 persons with replicating HCV infection, overall mortality declined from a maximum of 3.3 per 100 patient-years (PY) to 1.1 per 100 PY, and incidence of liver-related events decreased from 1.4/100 PY to 0.2/100 PY. CONCLUSIONS The introduction of DAA therapy was associated with a more than 10-fold reduction in prevalence of replicating HCV infection in PWH, approaching the estimates in the general population. Overall mortality and liver-related events declined substantially in persons living with HIV and hepatitis C.

Abstract
Background Epidemiological data are crucial to monitoring progress towards the 2030 Hepatitis C Virus (HCV) elimination targets. Our aim was to estimate the prevalence of chronic HCV infection (cHCV) in the European Union (EU)/European Economic Area (EEA) countries in 2019. Methods Multi-parameter evidence synthesis (MPES) was used to produce national estimates of cHCV defined as: π = πrecρrec + πexρex + πnonρnon; πrec, πex, and πnon represent cHCV prevalence among recent people who inject drugs (PWID), ex-PWID, and non-PWID, respectively, while ρrec, ρex, and ρnon represent the proportions of these groups in the population. Information sources included the European Centre for Disease Prevention and Control (ECDC) national operational contact points (NCPs) and prevalence database, the European Monitoring Centre for Drugs and Drug Addiction databases, and the published literature. Findings The cHCV prevalence in 29 of 30 EU/EEA countries in 2019 was 0.50% [95% Credible Interval (CrI): 0.46%, 0.55%]. The highest cHCV prevalence was observed in the eastern EU/EEA (0.88%; 95% CrI: 0.81%, 0.94%). At least 35.76% (95% CrI: 33.07%, 38.60%) of the overall cHCV prevalence in EU/EEA countries was associated with injecting drugs. Interpretation Using MPES and collaborating with ECDC NCPs, we estimated the prevalence of cHCV in the EU/EEA to be low. Some areas experience higher cHCV prevalence while a third of prevalent cHCV infections was attributed to PWID. Further efforts are needed to scale up prevention measures and the diagnosis and treatment of infected individuals, especially in the east of the EU/EEA and among PWID. Funding ECDC.

Int J Immunogenet 2023; 50:249-255. [PMID: 37658479 DOI: 10.1111/iji.12636] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2023] [Revised: 08/17/2023] [Accepted: 08/23/2023] [Indexed: 09/03/2023]
Abstract
Hepatitis C virus (HCV) infection is a major cause of chronic liver disease. Chronic HCV infection is also an important cause of hepatic fibrosis, cirrhosis and hepatocellular carcinoma (HCC). HCV has the capacity to evade immune surveillance by altering the host immune response. Moreover, variations in immune-related genes can lead to differential susceptibility to HCV infection as well as interfere on the susceptibility to the development of hepatic fibrosis, cirrhosis and HCC. The human leucocyte antigen G (HLA-G) gene codes for an immunomodulatory protein known to be expressed in the maternal-foetal interface and in immune-privileged tissues. The HLA-G 3' untranslated region (3'UTR) is important for mRNA stability, and variants in this region are known to impact gene expression. Studies, mainly focusing in a 14 bp insertion/deletion polymorphism, have correlated HLA-G 3'UTR with susceptibility to viral infections, but other polymorphic variants in the HLA-G 3'UTR might also affect HCV infection as they are inherited as haplotypes. The present study evaluated HLA-G 3'UTR polymorphisms and performed linkage disequilibrium test and haplotype assembly in 286 HCV infected patients who have developed fibrosis, cirrhosis or HCC, as well as in 129 healthy control subjects. Haplotypes UTR-1, UTR-2 and UTR-3 were the most observed in HCV+ patients, in the frequencies of 0.276, 0.255 and 0.121, respectively. No statistically significant difference was observed between HCV+ and control subjects, even when patients were grouped according to outcome (HCC, cirrhosis or fibrosis). Despite that, some trends in the results were observed, and therefore, we cannot rule out the possibility that variants associated to high HLA-G expression can be involved in HCV infection susceptibility.

Abstract
The field of hepatology has made impressive progress over its ~75 years of existence. Advances in understanding liver function and its dysregulation in disease, genetic determinants of disease, antiviral therapy, and transplantation have transformed the lives of patients. However, there are still significant challenges that require ongoing creativity and discipline, particularly with the emergence of fatty liver diseases, as well as managing autoimmune disease, cancer, and liver disease in children. Diagnostic advances are urgently needed to accelerate risk stratification and efficient testing of new agents with greater precision in enriched populations. Integrated, holistic care models should be extended beyond liver cancer to diseases like NAFLD with systemic manifestations or extrahepatic comorbidities such as cardiovascular disease, diabetes, addiction, and depressive disorders. To meet the growing burden of asymptomatic liver disease, the workforce will need to be expanded by incorporating more advanced practice providers and educating other specialists. The training of future hepatologists will benefit from incorporating emerging skills in data management, artificial intelligence, and precision medicine. Continued investment in basic and translational science is crucial for further progress. The challenges ahead are significant, but with collective effort, the field of hepatology will continue to make progress and overcome obstacles.

Abstract
BACKGROUND Patients infected with Hepatitis C virus (HCV) are recommended to receive treatment with direct-acting antiviral agents (DAAs), which have been certified to obtain a high sustained virological response (SVR). However, little is known about the benefits of successful anti-viral treatment to elderly patients with hepatic fibrosis. In this study, we aimed to assess degree of fibrosis in elderly patients with chronic hepatitis C (CHC) treated with DAAs, and to evaluate the correlations between identified factors associated with these changes. METHODS This study retrospectively enrolled elderly patients with CHC who received DAAs in Tianjin Second People's Hospital from April 2018 to April 2021. The degree of liver fibrosis was assessed using serum biomarkers and transient elastography (TE) expressed as the liver stiffness (LSM), while the hepatic steatosis was evaluated by controlled attenuated parameter (CAP). Changes in factors related to hepatic fibrosis were examined following treatment with DAAs, and associated prognostic factors were further evaluated. RESULTS We included 347 CHC patients in our analysis, where 127 of these were elderly patients. For the elderly group, the median LSM was 11.6 (7.9-19.9) kPa, and this value was significantly reduced to 9.7 (6.2-16.6) kPa following DAA treatment. Similarly, GPR, FIB-4 and APRI indices were significantly reduced from 0.445 (0.275-1.022), 3.072 (2.047-5.129) and 0.833 (0.430-1.540) to 0.231 (0.155-0.412), 2.100 (1.540-3.034) and 0.336 (0.235-0.528), respectively. While in younger patients, the median LSM reduced from 8.8 (6.1-16.8) kPa to 7.2 (5.3-12.4) kPa, and the trends of GPR, FIB-4 and APRI were also consistent. The CAP in younger patients increased with statistical significance, but we did not observe any significant change in CAP for the elderly group. Based on multivariate analysis, age, LSM, and CAP before baseline were identified as determinants for LSM improvement in the elderly. CONCLUSION In this study, we found that elderly CHC patients treated with DAA had significantly lower LSM, GPR, FIB-4, and APRI values. DAA treatment did not significantly change CAP. Furthermore, we observed correlations between three noninvasive serological evaluation markers and LSM. Finally, age, LSM, and CAP were identified as independent predictors of fibrosis regression in elderly patients with CHC.

Abstract
According to the French recommendations, the elimination of the hepatitis C virus by 2025 could be a realistic public health goal. Screening policies are being intensified, and access to treatment is promoted for patients who escape the usual care pathway. The 'Scanvir' program is an original strategy based on dedicated screening days, as part of the 'test, treat and cure HCV' event in addiction care centers in a French region, during which innovative screening technologies (RDTs, FibroScan® and point-of-care HCV RNA testing) are brought on site and access to a multidisciplinary team is offered. A total of 392 patients attended the 67 regional Scanvir sessions: 31.6% were HCV Ab-positive and 66% of them were HCV RNA-positive. Treatment was initiated in 79.3% of the patients. RDTs were accepted by 62% of the PWIDs (including those who already knew their status) and FibroScan® by 99.5% of the patients. 80% of the viremic patients started their treatment on site and are now cured or still under treatment. Advanced fibrosis evaluated by FibroScan® (LSM > 8 KPa) was suspected in 13.4% and 14.1% of the global and the HCV population, respectively. Scanvir is an efficient strategy for HCV elimination based on dedicated days aimed at increasing cost-effectiveness and offering a multidisciplinary service while saving human care resources. It is an exportable strategy that also offers comprehensive screening of associated chronic liver diseases via the elastometry device and interviews.

Abstract
Community-based screening for the hepatitis C virus (HCV) decreased during the COVID-19 pandemic. We developed a collaborative referral model between a primary clinic (Liouguei District Public Health Center, LDPHC) and a tertiary referral center to increase HCV screening and treatment uptake in a mountainous region of Taiwan. Once-in-a-lifetime hepatitis B and C screening services established by the Taiwan National Health Insurance were performed at LDPHC. Antibody-to-HCV (anti-HCV)-seropositive patients received scheduled referrals and took a shuttle bus to E-Da hospital for HCV RNA testing on their first visit. Direct-acting antiviral agents (DAAs) were prescribed for HCV-viremic patients on their second visit. From October 2020 to September 2022, of 3835 residents eligible for HCV screening in Liouguei District, 1879 (49%) received anti-HCV testing at LDPHC. The overall HCV screening coverage rate increased from 40% before referral to 69.4% after referral. Of the 79 anti-HCV-seropositive patients, 70 (88.6%) were successfully referred. Of the 38 HCV-viremic patients, 35 (92.1%) received DAA therapy, and 32 (91.4%) achieved sustained virological response. The collaborative referral model demonstrates a good model for HCV screening and access to care and treatment in a Taiwan mountainous region, even during the COVID-19 pandemic. Sustained referral is possible using this routine referral model.

Abstract
Breast cancer is a significant cause of morbidity and mortality in women, with over two million new cases reported worldwide each year, the majority of which occur in post-menopausal women. Despite advances in early detection and treatment, approximately one-third of patients diagnosed with breast cancer will develop metastatic disease. The pathogenesis and progression of breast cancer are influenced by a variety of biological and social risk factors, including age, ethnicity, pregnancy status, diet, and genomic alterations. Recent advancements in breast cancer research have focused on harnessing the power of the patient's adaptive and innate immune systems for diagnostic and therapeutic purposes. The breast immune microenvironment plays a critical role in regulating tissue homeostasis and resistance to tumorigenesis. In this review, we explore the dynamic changes in the breast immune microenvironment that occur with age, how these changes impact breast cancer development and progression, and how targeted therapeutic interventions that leverage the immune system can be used to improve patient outcomes. Our review emphasizes the importance of understanding the complex interplay between aging, the immune system, and breast cancer, and highlights the potential of immune-based therapies in the fight against this devastating disease.

Abstract
OBJECTIVES Incidence of hepatitis C virus (HCV) infection is increasing in women of reproductive age, leading to increased prevalence of HCV infection in children via vertical transmission. This quality improvement (QI) project aimed to increase referrals to and appointments scheduled with a specialty pediatric gastroenterology HCV clinic and the number of eligible children with HCV who completed treatment. METHODS From July 2020 to August 2021, the QI team designed a project using the Model for Improvement and completed Plan Do Study Act cycles to test change ideas to improve HCV awareness and education for medical providers and families; standardize the referral process; track patients; increase clinic capacity; and connect families with community resource care coordination. Referrals to the pediatric HCV clinic, appointments scheduled, no shows, and treatment follow-up were tracked during the project period and a comparison timeframe from July 2019 to June 2020. RESULTS There were improvements in several measures during the project period versus the comparison timeframe, with 80 versus 48 referrals received (66% increase), 115 versus 59 scheduled clinic visits (95% increase), and 7 versus 5 treatment completers (40% increase), along with a small (7%) decline in the proportion of scheduled clinic visits that were no shows. CONCLUSION Application of QI methodology increased medical provider and caregiver awareness and engagement in accessing HCV healthcare available for at-risk children. More QI efforts should be accelerated to identify best practices amidst a nationwide HCV epidemic.

HIV-HCV Incidence in Low-Wage Agricultural Migrant Workers Living in Ghettos in Apulia Region, Italy: A Multicenter Cross Sectional Study. Viruses 2023; 15:249. [PMID: 36680288 PMCID: PMC9861079 DOI: 10.3390/v15010249] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2022] [Revised: 01/06/2023] [Accepted: 01/14/2023] [Indexed: 01/17/2023] Open
Abstract
Migrant populations are more susceptible to viral hepatitis and HIV due to the epidemiology from their country of origin or their social vulnerability when they arrive in Europe. The aims of the study are to explore the incidence of HIV and HCV in low-wage agricultural migrant workers and their knowledge, attitude, and practice with regard to HIV and HCV, as well as their sexual behaviour and risk factors. As part of the mobile clinic services, we performed a screening campaign for HIV-HCV involving migrants living in three Apulian establishments. Results: Between January 2020 and April 2021, 309 migrants (n. 272, 88% male, mean age 28.5 years) were enrolled in the study. Most of the migrants interviewed (n = 297, 96%) reported a stopover in Libya during their trip to Italy. Only 0.9% (n. 3) of migrants reported having been tested for HCV, while 30.7% (n. 95) reported being tested for HIV. Furthermore, screening tests found four migrants (1.3%) to be HIV positive and nine (2.9%) to be HCV positive. The median knowledge score was 1 (IQR 0-3; maximum score: 6 points) for HCV and 3 (IQR 1-4; maximum score: 7 points) for HIV and low use of condoms was 5% (n. 16), while more than 95% show an attitude score of 5 (IQR 5-6; maximum score:6 points) on HIV-HCV education campaigns. In a multivariate analysis, being male (OR = 1.72; 95% CI 1.28−1.92), being single (OR = 1.63; 95% CI 1.20−2.03), being of low educational status (OR = 2.09; 95% CI 1.29−2.21), living in shantytowns for >12 months (OR = 1.95; 95% CI 1.25−2.55), and originating from the African continent (OR = 1.43; 95% CI 1.28−2.01) are significant predictors of poor knowledge on HCV. Our data show low knowledge, especially of HCV, confirming migrants as a population with a higher risk of infection. To develop education programmes, integrated care and screening among migrants could be an effective strategy, considering the high attitude toward these items shown in our study.

JOURNAL OF MEDICAL EDUCATION AND CURRICULAR DEVELOPMENT 2023; 10:23821205231184362. [PMID: 37378042 PMCID: PMC10291854 DOI: 10.1177/23821205231184362] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/23/2022] [Accepted: 06/02/2023] [Indexed: 06/29/2023]
Abstract
OBJECTIVES Improved knowledge of hepatitis C virus (HCV) screening, linkage to care, and treatment is needed among nonspecialist medical professionals to combat the HCV epidemic. The authors sought to implement and analyze the impact of an HCV curriculum for primary care professionals (PCPs) across the state of Vermont, USA. METHODS This investigation was a retrospective analysis of uptake of a Vermont HCV educational curriculum and its impact on HCV direct-acting antiviral (DAA) prescribing rates within the state before and after the study period. The curriculum was delivered online and in-person over 2 years from 2019 to 2020. The primary outcome was health care professional performance on a pre- and post-curriculum short-term knowledge assessment exam. The secondary outcome was assessing the number of unique healthcare professionals within a single payor database prescribing DAA treatment for HCV in Vermont before and after the study intervention, from January 1, 2017 until December 1, 2021. RESULTS There were 31 unique respondents on the pre- and post-intervention examinations, which represented 9% of known participants. Respondents included physicians (n = 15), nurse practitioners (n = 8), and nurses (n = 8). Pre- and post-intervention knowledge scores increased significantly across all provider groups, from 3.2 (SD 0.6) to 4.5 (SD 0.4) 1 to 5 scale (P = .01). The total number of unique HCV DAA therapy prescribers decreased over the study period, from 17 in 2017 to 9 in 2021. CONCLUSIONS A Vermont statewide HCV curriculum for PCPs was successful at increasing short-term HCV-related knowledge. However, this did not obviously translate to an increase in new professionals treating HCV.

Alzheimers Res Ther 2022; 14:171. [PMID: 36371267 PMCID: PMC9652901 DOI: 10.1186/s13195-022-01111-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2022] [Accepted: 10/31/2022] [Indexed: 11/13/2022]
Abstract
Introduction The effectiveness, safety, and cost-effectiveness of the use of Souvenaid for Alzheimer’s disease (AD) have been previously evidenced. To complete the economic analysis, there is a need to assess whether society can afford it. The objective of this study was to carry out a budget impact analysis of the use of Souvenaid in Spain under the conditions of the LipiDidiet clinical trial from a societal perspective. Methods We built a population model that took into account all the cohorts of individuals with AD, their individual progression, and the potential impact of Souvenaid treatment on their trajectories. Patient progression data were obtained from mixed models. The target population was estimated based on the population forecast for 2020–2035 and the incidence of dementia. Individual progression to dementia measured by the Clinical Dementia Rating-Sum of Boxes was reproduced using mixed models. Besides the costs of treatment and diagnosis, direct costs of medical and non-medical care and indirect costs were included. Results The epidemiological indicators and the distribution of life expectancy by stages validated the model. From the third year (2022), the differences in the cost of dementia offset the incremental cost of diagnosis and treatment. The costs of dependency reached €500 million/year while those of the intervention were limited to €40 million. Conclusions Souvenaid, with modest effectiveness in delaying dementia associated with AD, achieved a positive economic balance between costs and savings. Its use in the treatment of prodromal AD would imply an initial cost that would be ongoing, but this would be offset by savings in the care system for dependency associated with dementia from the third year. These results were based on adopting a societal perspective taking into account the effect of treatment on the use of health, social, and family resources.

Abstract
INTRODUCTION Patients with chronic hepatitis C (CHC) have an increased risk of atherosclerotic cardiovascular disease which may be due to inflammation and endothelial dysfunction caused by the chronic infection. In this prospective pilot study, we assessed, for the first time among patients with CHC the myocardial perfusion reserve (MPR) by Rubidium-82 (82 Rb) positron emission tomography (PET)/computed tomography (CT) before and after direct-acting antiviral (DAA) treatment and compared them with biomarkers of systemic inflammation and endothelial dysfunction. METHODS We included 10 patients with CHC who received 8 or 12 weeks of DAA treatment. To obtain the MPR, a cardiac 82 Rb PET/CT scan at rest and adenosine-induced stress was performed at baseline and between 12 and 24 weeks post DAA treatment. Additionally, markers of endothelial dysfunction and inflammation were measured at baseline and 12 weeks after DAA treatment. RESULTS All 10 patients achieved cure and the median age was 50 (range: 40-62 years). The median MPR before treatment was 3.1 (range: 2.3-4.8) compared to 2.9 (range: 2.2-4.1) after DAA treatment p = 0.63. Also, cure after DAA treatment was not associated with an overall significant decrease in markers of endothelial dysfunction and inflammation. DISCUSSION Cure after DAA treatment in patients with CHC did not improve coronary microvascular function nor did it lead to a decrease in soluble markers of cardiovascular risk in the given time frame where the patients were followed. It should be noted, that MPR before DAA treatment was in the normal range. Considering the small sample size and short follow-up time, further studies are warranted to determine if viral clearance has an effect on coronary microvascular function and endothelial dysfunction.

Abstract
CONTEXT Birth cohort ("baby boomer") screening represents a well-validated strategy for the identification of asymptomatic hepatitis C-infected patients. However, successful linkage of newly diagnosed patients to antiviral therapy has been more difficult to accomplish. OBJECTIVE To analyze the results of a systemwide birth cohort screening program in a US community health care system. DESIGN We analyzed the data from an ongoing hepatitis C virus (HCV) screening and treatment program that was established at NorthShore University Health System in 2015. Hepatitis C virus screening by primary care providers was prompted through automated Best Practice and Health Maintenance alerts. Patient visits and screening orders were tracked using a customized HCV dashboard. Virologic, demographic, and treatment data were assessed and compared with those of a cohort of patients with previously established HCV infection. RESULTS Since program inception, 61 8161 (64.3%) of the entire NorthShore baby boomer population of 96 001 patients have completed HCV antibody testing, and 160 patients (0.26%) were antibody positive. Of 152 antibody-positive patients who underwent HCV RNA testing, 53 (34.2%) were viremic. A total of 39 of 53 patients (73.6%) underwent antiviral therapy and achieved a sustained virologic response. Compared with patients identified through screening, a comparison cohort of patients with previously established HCV had more advanced fibrosis and significantly lower dropout rates. The COVID-19 pandemic was associated with a decrease in the number of outpatient visits of screening-eligible patients and with a reduction in HCV screening rates. CONCLUSION Our data demonstrate the electronic medical records-assisted systemwide implementation of HCV birth cohort screening and successful linkage to antiviral therapy in a community-based US multihospital system.

Abstract
We report a quantification of the decrease of effectiveness of antiviral agents directed to hepatitis C virus, when the agents are added during an ongoing infection in cell culture vs. when they are added at the beginning of the infection. Major determinants of the decrease of inhibitory activity are the time post-infection of inhibitor administration and viral replicative fitness. The efficacy decrease has been documented with antiviral assays involving the combination of the direct-acting antiviral agents, daclatasvir and sofosbuvir, and with the combination of the lethal mutagens, favipiravir and ribavirin. The results suggest that strict antiviral effectiveness assays in preclinical trials may involve the use of high fitness viral populations and the delayed administration of the agents, relative to infection onset.

Abstract
The orthopedic environment exposes surgeons and staff to infection, surgical smoke, and high levels of noise. It is helpful to understand how exposure increases the risk for adverse health consequences. Protective equipment, safety protocols, and instrument modification can reduce exposure to hazards. When modifications to practice are made, they must be evaluated to ensure they do not introduce new hazards or impede the use of instruments. Despite evidence of risk, protective measures are seldom employed in orthopedic practice. Wider implementation of protection for clinicians may not occur unless the same hazards are shown to impact patient outcomes.

Abstract
OBJECTIVES The current study aimed to assess the impact of HIV on the production of anti-HCV antibodies in HCV-infected individuals with advanced HCV-related cirrhosis before and 36 weeks after the sustained virological response (SVR) induced by direct-acting antivirals (DAAs) therapy. METHODS Prospective study on 62 patients (50 HIV/HCV-coinfected and 12 HCV-monoinfected). Plasma anti-E2 and HCV-nAbs were determined respectively by ELISA and microneutralization assays. RESULTS At baseline, the HCV-group had higher anti-E2 levels against Gt1a (p = 0.012), Gt1b (p = 0.023), and Gt4a (p = 0.005) than the HIV/HCV-group. After SVR, anti-E2 titers against Gt1a (p < 0.001), Gt1b (p = 0.001), and Gt4a (p = 0.042) were also higher in the HCV-group than HIV/HCV-group. At 36 weeks post-SVR, plasma anti-E2 titers decreased between 1.3 and 1.9-fold in the HIV/HCV-group (p < 0.001) and between 1.5 and 1.8-fold in the HCV-group (p ≤ 0.001). At baseline, the HCV-group had higher titers of HCV-nAbs against Gt1a (p = 0.022), Gt1b (p = 0.002), Gt2a (p < 0.001), and Gt4a (p < 0.001) than the HIV/HCV-group. After SVR, HCV-nAbs titers against Gt1a (p = 0.014), Gt1b (p < 0.001), Gt2a (p = 0.002), and Gt4a (p = 0.004) were also higher in the HCV-group. At 36 weeks post-SVR, HCV-nAbs decreased between 2.6 and 4.1-fold in the HIV/HCV-group (p < 0.001) and between 1.9 and 4.0-fold in the HCV-group (p ≤ 0.001). CONCLUSIONS HIV/HCV-coinfected patients produced lower levels of broad-spectrum anti-HCV antibodies than HCV-monoinfected patients.

Sugrue JA, O’Farrelly C. Uncovering Resistance to Hepatitis C Virus Infection: Scientific Contributions and Unanswered Questions in the Irish Anti-D Cohort. Pathogens 2022; 11:pathogens11030306.

Abstract
Infections caused inadvertently during clinical intervention provide valuable insight into the spectrum of human responses to viruses. Delivery of hepatitis C virus (HCV)-contaminated blood products in the 70s (before HCV was identified) have dramatically increased our understanding of the natural history of HCV infection and the role that host immunity plays in the outcome to viral infection. In Ireland, HCV-contaminated anti-D immunoglobulin (Ig) preparations were administered to approximately 1700 pregnant Irish rhesus-negative women in 1977–1979. Though tragic in nature, this outbreak (alongside a smaller episode in 1993) has provided unique insight into the host factors that influence outcomes after HCV exposure and the subsequent development of disease in an otherwise healthy female population. Despite exposure to highly infectious batches of anti-D, almost 600 of the HCV-exposed women have never shown any evidence of infection (remaining negative for both viral RNA and anti-HCV antibodies). Detailed analysis of these individuals may shed light on innate immune pathways that effectively block HCV infection and potentially inform us more generally about the mechanisms that contribute to viral resistance in human populations.

Abstract
Hepatitis C virus infection has a substantial effect on morbidity and mortality worldwide because it is a cause of cirrhosis, hepatocellular carcinoma, liver transplantation, and liver-related death. Direct acting antiviral drugs available today have high efficacy and excellent safety and can be used in all patients with clinically evident chronic liver disease and in groups that demonstrate risk behaviors to reduce the spread of infection. The Global Health Strategy of WHO to eliminate hepatitis infection by 2030 assumes "a 90% reduction in new cases of chronic hepatitis C, a 65% reduction in hepatitis C deaths, and treatment of 80% of eligible people with HCV infections". In this review effective models and strategies for achieving the global elimination of HCV infection are analyzed. The screening strategies must be simple and equally effective in high-risk groups and in the general population; fast and effective models for appropriate diagnosis of liver disease are needed; strategies for direct acting antiviral drug selection must be cost-effective; linkage to care models in populations at risk and in marginalized social classes must be specifically designed and applied; strategies for obtaining an effective vaccine against HCV infection have yet to be developed.

Abstract
In the course of experiments aimed at deciphering the inhibition mechanism of mycophenolic acid and ribavirin in hepatitis C virus (HCV) infection, we observed an inhibitory effect of the nucleoside guanosine (Gua). Here, we report that Gua, and not the other standard nucleosides, inhibits HCV replication in human hepatoma cells. Gua did not directly inhibit the in vitro polymerase activity of NS5B, but it modified the intracellular levels of nucleoside di- and tri-phosphates (NDPs and NTPs), leading to deficient HCV RNA replication and reduction of infectious progeny virus production. Changes in the concentrations of NTPs or NDPs modified NS5B RNA polymerase activity in vitro, in particular de novo RNA synthesis and template switching. Furthermore, the Gua-mediated changes were associated with a significant increase in the number of indels in viral RNA, which may account for the reduction of the specific infectivity of the viral progeny, suggesting the presence of defective genomes. Thus, a proper NTP:NDP balance appears to be critical to ensure HCV polymerase fidelity and minimal production of defective genomes.

Abstract
INTRODUCTION AND OBJECTIVES In 1999, a population-based survey showed a 5.6 % (102/1832) prevalence of HCV infection in O'Brien, a small rural town of Argentina. The aim of this study was to assess the impact of screening, clinical evaluation and antiviral therapy on elimination of HCV after 20 years of follow-up. PATIENTS AND METHODS HCV+ subjects (n=102) underwent clinical, biochemical and histological evaluation to assess the presence and severity of liver disease. Antiviral therapy included pegylated interferon + ribavirin in 2005 and direct antiviral agents from 2017. RESULTS All viremic subjects (n=84) had genotype 1b with 90%-97.5% sequence homology scores, suggesting the existence of a common source of infection (use of unsafe injections administered by the same health professional). Liver biopsy (n=55) showed chronic hepatitis in all patients. The prevalence of cirrhosis was 28% overall (29/102) and 34.5% among viremic patients. Sustained virological response (SVR) was obtained in 20/34 (59%) patients treated with interferon. From 2005 to 2017, when oral antivirals became available 37/50 untreated patients died. Median age of this group in 2005 was 67 years. Six interferon non-responders and five naive subjects received direct antiviral agents and all developed SVR. Only 1/31 patient (3.2%) with SVR died and none developed decompensated cirrhosis or HCC. In 2019, a new population-based study showed that the prevalence of HCV in O'Brien decreased 20-fold, from 5.6% to 0.28% (3/1070). CONCLUSIONS Despite the high mortality rate precluding timely access to direct antiviral agents, the O'Brien Project is a good example of HCV micro-elimination studies.

Abstract
BACKGROUND The advent of direct-acting antiviral therapy for Hepatitis C (HCV) has made using HCV-viremic donors a viable strategy to address the donor shortage in heart transplantation. We employed a large-scale simulation to evaluate the impact and cost-effectiveness of using HCV-viremic donors for heart transplant. METHODS We simulated detailed histories from time of listing until death for the real-world cohort of all adults listed for heart transplant in the United States from July 2014 to June 2019 (n = 19,346). This population was imputed using historical data and captures "real-world" heterogeneity in geographic and clinical characteristics. We estimated the impact of an intervention in which all candidates accept HCV+ potential donors (n = 472) on transplant volume, waitlist outcomes, and lifetime costs and quality-adjusted life years (QALYs). RESULTS The intervention produced 232 more transplants, 132 fewer delistings due to deterioration, and 50 fewer waitlist deaths within this 5-year cohort and reduced wait times by 3% to 11% (varying by priority status). The intervention was cost-effective, adding an average of 0.08 QALYs per patient at a cost of $124 million ($81,892 per QALY). DAA therapy and HCV care combined account for 11% this cost, with the remainder due to higher costs of transplant procedures and routine post-transplant care. The impact on transplant volume varied by blood type and region and was correlated with donor-to-candidate ratio (ρ = 0.71). CONCLUSIONS Transplanting HCV+ donor hearts is likely to be cost-effective and improve waitlist outcomes, particularly in regions and subgroups experiencing high donor scarcity.

Abstract
HCV treatment became available for all infected patients regardless of their comorbidities, especially for HIV coinfected subjects, leading to an improvement in both clinical and immunological conditions. We retrospectively analyzed a cohort of HIV/HCV coinfected patients treated with DAA therapies; data regarding epidemiological, viral-immunological, and hepatic parameters before and after DAA administration have been collected. Drug-drug interactions between DAA and both antiretroviral therapy and non-ART-drugs were also evaluated; the study showed the efficacy of DAA schedules in HCV eradication also for HIV/HCV patients with multiple comorbidities and assuming many different drugs. Principal issues are still represented by drug interactions, pill burden, and patients' compliance. These concerns have to be taken into account, especially in HIV patients for whom the immunological state and ART interactions should always be considered.

Abstract
Over the past two decades, the epidemiology of chronic liver disease has changed with an increase in the prevalence of nonalcoholic fatty liver disease in parallel to the advent of curative treatments for hepatitis C. Recent developments provided new tools for diagnosis and monitoring of liver diseases based on ultrasound (US), computed tomography (CT), and magnetic resonance imaging (MRI), as applied for assessing steatosis, fibrosis, and focal lesions. This narrative review aims to discuss the emerging approaches for qualitative and quantitative liver imaging, focusing on those expected to become adopted in clinical practice in the next 5 to 10 years. While radiomics is an emerging tool for many of these applications, dedicated techniques have been investigated for US (controlled attenuation parameter, backscatter coefficient, elastography methods such as point shear wave elastography [pSWE] and transient elastography [TE], novel Doppler techniques, and three-dimensional contrast-enhanced ultrasound [3D-CEUS]), CT (dual-energy, spectral photon counting, extracellular volume fraction, perfusion, and surface nodularity), and MRI (proton density fat fraction [PDFF], elastography [MRE], contrast enhancement index, relative enhancement, T1 mapping on the hepatobiliary phase, perfusion). Concurrently, the advent of abbreviated MRI protocols will help fulfill an increasing number of examination requests in an era of healthcare resource constraints.

Abstract
About 4% of the population in Taiwan are seropositive for anti-HCV Ab and 70% with HCV RNA. To address this high chronic hepatitis C disease load, Taiwan National Health Insurance started reimbursing genotype-specific DAAs in 2017 and pangenotype DAAs in mid-2018. With a 97% SVR12 rate, there were still 2-3% of patients that failed to clear HCV. To understand the causes of DAA failure in Taiwan, we conducted a multi-center, clinical, and virologic study. A total of 147 DAA-failure patients were recruited, and we searched HCV NS3/4A, NS5A and NS5B for known resistance-associated substitutions (RASs) by population sequencing, and conducted whole genome sequencing (WGS) for those without known RASs. A total of 107 patients received genotype-specific DAAs while 40 had pangenotype DAAs. Clinically, the important cause of failure is poor adherence. Virologically, common RASs in genotype-specific DAAs were NS5A-L31, NS5A-Y93, and NS5B-C316, while common RASs in pangenotype DAAs were NS5A-L31, NS5A-A/Q/R30, and NS5A-Y93. Additionally, new amino acid changes were found by WGS. Finally, we identified 12 cases with inconsistent baseline and post-treatment HCV genotypes, which is suggestive of re-infection rather than treatment failure. Our study described the drug resistance profile for DAA failure in Taiwan, showing differences from other countries.

Peripheral neuropathy after viral eradication with direct-acting antivirals in chronic HCV hepatitis: A prospective study. Liver Int 2021; 41:2611-2621. [PMID: 34219359 PMCID: PMC8596576 DOI: 10.1111/liv.15002] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/25/2021] [Revised: 06/16/2021] [Accepted: 06/21/2021] [Indexed: 01/13/2023]
Abstract
BACKGROUND HCV-related extra-hepatic complications include peripheral neuropathies, with important prevalence and impact. A recent metanalysis of previous intervention trials concluded for insufficient data to support evidence-based treatments for this complication. In this longitudinal study, we assessed for the first time prevalence and outcome of neuropathy in a cohort of patients with chronic HCV, before and after direct-acting antiviral agent (DAA) treatment. METHOD Ninety-four patients (mean age 58.5 ± 9.9, infection duration 22.2 ± 6.3 years) without systemic and metabolic diseases, underwent neurological examination and electroneurography studies before (T0) and 10.4 ± 1.7 months after the end of DAA therapy (T1), and cryoglobulins (CG) assessment. Muscle strength was evaluated by Medical Research Council (MRC) score; neuropathic pain, sensory function, disability, quality of life were assessed by validated questionnaires (DN4, NPSI, SSS, INCAT and Euro-QoL). RESULTS At T0, sensory-motor neuropathy was detected in 22 patients (23%), reflexes were depressed in 32 (34%) with no association with infection duration, viral load, age, CG. Neuropathic pain (DN4 ≥4) was present in 37 patients (39%). At T1, out of the 22 patients with altered electroneurography, 3 had died or developed HCC, 4 showed normal electroneurography, and nerve amplitude parameters tended to improve in the whole group. Only 11 patients (12%) had depressed reflexes and 10 (11%) DN4 ≥4 (P < .05 compared to T0). Scores for MRC, questionnaires and Euro-QoL improved significantly (P < .05). CONCLUSION Our study confirms the high prevalence of clinical and subclinical peripheral sensory-motor neuropathy in patients with HCV infection and indicates improvement after eradication by DAA. These results support the need for larger intervention studies.

Abstract
Chronic hepatitis C virus (HCV) infection is correlated with cerebrovascular and cardiovascular disease (CVD). This study aimed to assess the effect of treatment with DAAs on vascular endothelial function in cirrhotic and non-cirrhotic HCV infected patients without any CVD risk factors. Fifty chronic HCV genotype 4 infected patients, without cardiovascular risks who have been listed to receive sofosbuvir/daclatasvir with ribavirin combination as triple therapy for 3 months were prospectively recruited. Endothelial dysfunction markers as soluble vascular cell adhesion molecule-1 (sVCAM-1) and Von willebrand factor (vWf) and inflammation marker (IL6) were estimated at baseline and 3 months post the end of therapy (SVR). All patients achieved SVR. VCAM1 level was significantly improved after HCV clearance with DAA in cirrhotic HCV patients (P = 0.002) compared to patients with mild liver fibrosis (P = 0.006). Levels of vWF also decreased significantly in cirrhosis and non-cirrhosis groups after SVR (P < 0.001 and P = 0.011, respectively). Systemic inflammatory marker (IL6) showed significant decrease in cirrhotic patients (P = 0.001). While, IL6 level did not change significantly in non-cirrhotic group (P = 0.061). Also at SVR, noninvasive liver fibrosis indices have been reduced significantly in the two groups (P < 0.001). HCV clearance by new DAA treatment improves the vascular endothelial dysfunction in Egyptian HCV infected patients with different levels of liver fibrosis and with no risk factors for endothelial dysfunction or CVD.

Abstract
In this paper, a new mathematical model is formulated that describes the interaction between uninfected cells, infected cells, viruses, intracellular viral RNA, Cytotoxic T-lymphocytes (CTLs), and antibodies. Hence, the model contains certain biological relations that are thought to be key factors driving this interaction which allow us to obtain precise logical conclusions. Therefore, it improves our perception, that would otherwise not be possible, to comprehend the pathogenesis, to interpret clinical data, to control treatment, and to suggest new relations. This model can be used to study viral dynamics in patients for a wide range of infectious diseases like HIV, HPV, HBV, HCV, and Covid-19. Though, analysis of a new multiscale HCV model incorporating the immune system response is considered in detail, the analysis and results can be applied for all other viruses. The model utilizes a transformed multiscale model in the form of ordinary differential equations (ODE) and incorporates into it the interaction of the immune system. The role of CTLs and the role of antibody responses are investigated. The positivity of the solutions is proven, the basic reproduction number is obtained, and the equilibrium points are specified. The stability at the equilibrium points is analyzed based on the Lyapunov invariance principle. By using appropriate Lyapunov functions, the uninfected equilibrium point is proven to be globally asymptotically stable when the reproduction number is less than one and unstable otherwise. Global stability of the infected equilibrium points is considered, and it has been found that each equilibrium point has a specific domain of stability. Stability regions could be overlapped and a bistable equilibria could be found, which means the coexistence of two stable equilibrium points. Hence, the solution converges to one of them depending on the initial conditions.

Abstract
Direct-acting antivirals (DAAs) are used for hepatitis C virus (HCV) treatment. However, treatment failure and hepatocellular carcinoma (HCC) development following treatment was reported. In this study, we assessed the role of serum vitamin D, interleukin 13 (IL-13), and microRNA-135a in the prediction of treatment failure with DAA and HCC development among Egyptian HCV-infected patients. A total of 950 patients with HCV-related chronic liver disease underwent DAA treatment. Before DAAs, serum vitamin D and IL-13 were determined by ELISA, and gene expression of miRNA-135a was assessed in serum by real-time PCR. The predictive abilities of these markers were determined using the receiver operating characteristic (ROC) curve. Sustained virological response (SVR) was achieved in 92.6% of HCV-infected patients (responders). High viral load, IL-13, miRNA-135a, and low vitamin D levels were associated with treatment failure and HCC development. HCC development was recorded in non-responders, but not in the responders (35.7% vs. 0% p < 0.001). In conclusion: serum IL-13, Vitamin D, and miRNA-135a could be potential biomarkers in monitoring DAA treatment and HCC prediction. DAAs-induced SVR may decrease the incidence of HCC.

Trends in the Economic Burden of Chronic Liver Diseases and Cirrhosis in the United States: 1996-2016. Am J Gastroenterol 2021; 116:2060-2067.

Abstract
INTRODUCTION The management of chronic liver diseases (CLDs) and cirrhosis is associated with substantial healthcare costs. We aimed to estimate trends in national healthcare spending for patients with CLDs or cirrhosis between 1996 and 2016 in the United States. METHODS National-level healthcare expenditure data developed by the Institute for Health Metrics and Evaluations for the Disease Expenditure Project and prevalence of CLDs and cirrhosis derived from the Global Burden of Diseases Study were used to estimate temporal trends in inflation-adjusted US healthcare spending, stratified by setting of care (ambulatory, inpatient, emergency department, and nursing care). Joinpoint regression was used to evaluate temporal trends, expressed as annual percent change (APC) with 95% confidence intervals (CIs). Drivers of change in spending for ambulatory and inpatient services were also evaluated. RESULTS Total expenditures in 2016 were $32.5 billion (95% CI, $27.0-$40.4 billion). Over 65% of spending was for inpatient or emergency department care. From 1996 to 2016, there was a 4.3%/year (95% CI, 2.8%-5.8%) increase in overall healthcare spending for patients with CLDs or cirrhosis, driven by a 17.8%/year (95% CI, 14.5%-21.6%) increase in price and intensity of hospital-based services. Total healthcare spending per patient with CLDs or cirrhosis began decreasing after 2008 (APC -1.7% [95% CI, -2.1% to -1.2%]), primarily because of reductions in ambulatory care spending (APC -9.1% [95% CI, -10.7% to -7.5%] after 2011). DISCUSSION Healthcare expenditures for CLDs or cirrhosis are substantial in the United States, driven disproportionately by acute care in-hospital spending.

Abstract
Introduction: Hepatitis C (HCV) is viral disease with a global impact. Over the last 10 years, the treatment of this disease has evolved. Treatment guidelines have evolved to adopt new medications for HCV. These drugs have shown efficacy over 90% throughout the class as well as a better safety profile than the previous recommended pharmacotherapy. Dual-therapy DAAs emerged with FDA approval of Ledipasvir/Sofosbuvir (LDV/SOF) in 2014.Areas Covered: LDV/SOF is a dual-therapy option for chronic HCV patients (>6 months of infection) in select genotypes. This article reviews the studies relevant to the pharmacokinetic/pharmacodynamic properties of these drugs as well as its trials leading to approval.Expert opinion: LDV/SOF is included in the AASLD/IDSA guidelines for the treatment of HCV genotypes 1a and 1b with or without cirrhosis and genotype 4 without cirrhosis with an evidence and recommendation rating of IA. Genotype 4 with cirrhosis and genotypes 5 and 6 carry a Class IIa level B recommendation. The combination is not FDA approved for genotypes 2 and 3. Single-pill regimens, like LDV/SOF, are important to maintain the quality of life of children and other special populations infected with HCV by shortening treatment regimens, avoiding complex pill regimens, and eliminating injection therapies.

Abstract
BACKGROUND & AIMS The risk for hepatitis C virus (HCV) recurrence persists after HCV eradication with direct-acting antivirals (DAAs), particularly in patients with ongoing high-risk behaviours. Our aim was to assess the risk of HCV recurrence (late relapse and/or reinfection) post-sustained virological response (SVR). METHODS We searched the literature for studies reporting HCV recurrence rates post-SVR in PubMed, Web of Science and the Cochrane Library. Identified publications were divided into groups based on patient risk for HCV reinfection: low-risk HCV mono-infection, high-risk HCV mono-infection and a human immunodeficiency virus (HIV)/HCV coinfection. The HCV recurrence rate for each study was calculated by using events divided by the person-years of follow-up (PYFU). HCV recurrence was defined as confirmed, detectable HCV RNA post-SVR. RESULTS In the 16 studies of low-risk patients, the pooled recurrence rate was 0.89/1000 PYFU (95% confidence interval [CI], 0.16-2.03). For the 19 studies of high-risk patients, the pooled recurrence rate was 29.37/1000 PYFU (95% CI, 15.54-46.91). For the eight studies of HIV/HCV-coinfected patients, the pooled recurrence rate was 23.25/1000 PYFU (95% CI, 4.24-53.39). The higher pooled estimates of recurrence in the high-risk and HIV/HCV-coinfected populations were predominantly driven by an increase in reinfection rather than late relapse. CONCLUSIONS The HCV recurrence risk after achieving SVR with all-oral DAAs therapy is low, and the risk of HCV recurrence in high-risk and HIV/HCV-coinfected populations was driven by an increase in reinfection rather than late relapse.

Improving healthcare for patients with HIV, tuberculosis and hepatitis C in eastern Europe: a review of current challenges and important next steps. HIV Med 2021; 23:48-59.

Abstract
OBJECTIVES In some eastern European countries, serious challenges exist to meet the HIV-, tuberculosis (TB)- and hepatitis-related target of the United Nations Sustainable Development Goals. Some of the highest incidence rates for HIV and the highest proportion of multi-drug-resistant (MDR) tuberculosis worldwide are found in the region. The purpose of this article is to review the challenges and important next steps to improve healthcare for people living with TB, HIV and hepatitis C (HCV) in eastern Europe. METHODS References for this narrative review were identified through systematic searches of PubMed using pre-idientified key word for articles published in English from January 2000 to August 2020. After screening of titles and abstracts 37 articles were identified as relevant for this review. Thirty-eight further articles and sources were identified through searches in the authors' personal files and in Google Scholar. RESULTS Up to 50% of HIV/MDR-TB-coinfected individuals in the region die within 2 years of treatment initiation. Antiretroviral therapy (ART) coverage for people living with HIV (PLHIV) and the proportion virological suppressed are far below the UNAIDS 90% targets. In theory, access to various diagnostic tests and treatment of drug-resistant TB exists, but real-life data point towards inadequate testing and treatment. New treatments could provide elimination of viral HCV in high-risk populations but few countries have national programmes. CONCLUSION Some eastern European countries face serious challenges to achieve the sustainable development goal-related target of 3.3 by 2030, among others, to end the epidemics of AIDS and tuberculosis. Better integration of healthcare systems, standardization of health care, unrestricted substitution therapy for all people who inject drugs, widespread access to drug susceptibility testing, affordable medicines and a sufficiently sized, well-trained health workforce could address some of those challenges.

A large number of chronic hepatitis C patients had been successfully treated by directly acting antivirals; therefore, strategies for the long-term follow-up of these patients have to be planned based on the post-treatment fibrosis stage—the main determinant of prognosis. In this study, we aim to evaluate changes in aspartate-platelet ratio index, FIB4, and liver stiffness in chronic hepatitis C patients who achieved SVR and ended treatment more than 1 year by DAAs.
Results
One hundred chronic hepatitis C patients who achieved SVR were enrolled at a median of 16 months after the end of treatment by DAAs. According to the baseline liver stiffness, 63 and 37 patients belonged to early (F0, F1, and F2) and advanced (F3 and F4) fibrosis stages, respectively. Both groups showed a decline of the degree of liver stiffness at follow-up compared to the baseline that was statistically significant in the early fibrosis group (5.9±1.5 vs 5.4±2.2 Kpcal, p=0.04), while measurements in the advanced group were (18±8.8 vs 15.9 ± 7.8 Kpcal, p=0.07). Also, serum biomarkers of fibrosis improved in both groups, where the recorded APRI and FIB4 before and after treatment were 0.42±0.3 vs 0.24±0.1, p<0.01 and 1±0.6 vs 0.93 ±0.5, p=0.1 in the early group and 0.85 ±0.5 vs 0.4±0.2, p <0.001 and 2.9±2.3 vs 1.8±1.4, p<0.02) in the advanced group, respectively. Changes in APRI and FIB4 correlated with changes in AST and ALT, but liver stiffness changes were not affected by changes in liver enzymes.
Conclusion
Although long-term improvement of APRI, FIB4, and liver stiffness scores could be achieved in chronic HCV patients after SVR by DAAS. High measurements of liver stiffness before treatment likely persist. We recommend transient elastography as a reliable tool for fibrosis assessment post-treatment.

[PMID: 32066209 PMCID: PMC7667921 DOI: 10.5009/gnl19296] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/29/2019] [Revised: 11/07/2019] [Accepted: 11/25/2019] [Indexed: 12/13/2022] Open
Abstract
Background/Aims To eliminate hepatitis C virus (HCV) infection, improving public knowledge of and access to HCV screening and treatment is essential. The aim of this study was to evaluate the knowledge of and testing rate for HCV and the opinions about the inclusion of the HCV test in the National Health Examination (NHE) among the general population in South Korea. Methods A telephone interview survey was conducted by an independent research company using a 16 item-questionnaire (demographics, knowledge of HCV, testing and results, need for screening) in May 2019. The sample population consisted of 1,003 adult Korean residents adjusted by age, sex, and area according to the standard Korean population in 2019. Results Among the 1,003 participants (505 women, mean age of 47.9 years), 56.4% recognized HCV; 44.4% understood that HCV is transmittable, and 56.8% thought that HCV is curable by medication. The recognition rate tended to increase with an increasing level of education. Testing for anti-HCV antibodies was reported by 91 people (9.1%); among them, 10 people (11.0%) reported a positive result, and eight people received treatment. The common reasons for HCV testing were a health check-up (58.5%), a physician's recommendation (11.0%) and elevated liver enzyme levels (10.7%). The majority of the population (75.1%) agreed with the integration of HCV into the NHE. Conclusions The level of knowledge of HCV is suboptimal, and the self-reported testing rate for HCV is less than 10%; however, once HCV infection is diagnosed, the treatment rate seems to be high in South Korea. More active campaigns and effective screening are needed.

Clin Gastroenterol Hepatol 2021; 19:1670-1678. [PMID: 32835844 DOI: 10.1016/j.cgh.2020.08.042] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/27/2020] [Revised: 08/05/2020] [Accepted: 08/14/2020] [Indexed: 02/07/2023]
Abstract
BACKGROUND AND AIMS Recent case series and retrospective studies have raised concerns that patients who receive direct-acting antiviral (DAA) treatment for hepatitis C virus (HCV) infection are at increased risk of developing varicella-zoster virus infection (VZV reactivation). We investigated the relationship between DAA treatment and VZV reactivation by analyzing pooled participant-level data from 37 clinical trials of DAA agents. METHODS We obtained demographic, adverse event, and laboratory data from 13,816 participants in 37 clinical trials submitted to the Food and Drug Administration for approval of DAA agents for treatment of HCV infection. Participants received DAAs (n = 12,249), placebo (n = 997), pegylated interferon (n = 243), or a combination of DAAs and pegylated interferon (n = 327). Occurrence of VZV reactivation was identified using systematically reported adverse event data. HCV virologic response was evaluated by measurement of HCV RNA. RESULTS VZV reactivation occurred in 9.9 cases per 1000 person-years of DAA treatment (95% CI, 6.8-14.0 per 1000 person years) and 13.8 cases per 1000 person-years of placebo (95% CI, 3.5-37.5 per 1000 person years). No participants in the pegylated interferon or combination DAA and pegylated interferon groups experienced VZV reactivation. Within the placebo-controlled trials there was no significant difference in VZV reactivation between DAA treatment and placebo. VZV reactivation was associated with age older than 40 years, female sex, and HIV coinfection. We did not find an association between time of virologic response and time to VZV reactivation. CONCLUSION In an analysis of data from 37 trials, we found no evidence for an association between DAA treatment for HCV infection and increased risk of VZV reactivation.

Differential Expression of the Host Lipid Regulators ANGPTL-3 and ANGPTL-4 in HCV Infection and Treatment. Int J Mol Sci 2021; 22:ijms22157961. [PMID: 34360721 PMCID: PMC8348577 DOI: 10.3390/ijms22157961] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2021] [Revised: 07/20/2021] [Accepted: 07/22/2021] [Indexed: 11/29/2022] Open
Abstract
Host lipid metabolism reprogramming is essential for hepatitis C virus (HCV) infection and progression to severe liver disease. Direct-acting antivirals (DAAs) achieve a sustained virological response (SVR) in most patients, but virus eradication does not always protect against hepatocellular carcinoma (HCC). Angiopoietin-like protein-3 (ANGPTL-3) and angiopoietin-like protein-4 (ANGPTL-4) regulate the clearance of plasma lipids by inhibiting cellular lipase activity and possess emerging roles in tumourigenesis. We used ELISA and RT-qPCR to investigate ANGPTL-3 and ANGPTL-4 expression in HCV patients with characterised fibrosis throughout the natural history of hepatitis C and in long-term HCV infection in vitro, before and after DAA treatment. ANGPTL-3 was decreased in patients with advanced fibrosis compared to other disease stages, while ANGPTL-4 was progressively increased from acute infection to cirrhosis and HCC, peaking at the advanced fibrosis stage. Only ANGPTL-3 mRNA was down-regulated during early infection in vitro, although both ANGPTLs were increased later. DAA treatment did not alter ANGPTL-3 levels in advanced fibrosis/cirrhosis and in HCV infection in vitro, in contrast to ANGPTL-4. The association between ANGPTLs and fibrosis in HCV infection was underlined by an inverse correlation between the levels of ANGPTLs and serum transforming growth factor- β (TGF-β). Collectively, we demonstrate the pivotal role of advanced fibrosis in defining the expression fate of ANGPTLs in HCV infection and after treatment and propose a role for ANGPTL-3 as a contributor to post-treatment deregulation of lipid metabolism that could predispose certain individuals to HCC development.

Abstract
We aimed to assess the pregnancy outcome in women with chronic HCV who had negative pregnancy test prior to the anti-HCV course and had unintended pregnancy while on HCV treatment. Hundred patients with a mean age of 30 ± 6.7 y were included and advised to withhold antivirals and continue follow-up in viral hepatitis and obstetrics centres till delivery. All patients received a 12-weeks regimen of anti-HCV [sofosbuvir plus daclatasvir (SOF/DCV): n = 95, SOF/DCV plus ribavirin: n = 3, and paritaprevir/ritonavir/ombitasvir plus ribavirin: n = 2]. Only nine patients completed the full antiviral course against medical advice, and 91 stopped between on-treatment weeks 4 and 8. Eighty-eight patients delivered full-term babies, eight had preterm babies and two had abortions. Of the nine patients who completed the full course of DAAs, seven (77.8%) delivered normal babies, attended their post-treatment week 12 visit, and all (100%) achieved sustained virological response. No major antiviral-related adverse events were reported.

Abstract
Hepatitis C virus (HCV) prevalence is high among people living with HIV co-infected with HCV, people who inject drugs, men who have sex with men and inmates in correctional settings. The barriers to eliminate HCV among these key populations include diagnosis challenges, lack of awareness, discrimination and stigmatization. In addition, scaling up of HCV treatment has been a challenge in Asia–Pacific with the lack of national policies, targets and unavailability of appropriate direct-acting antivirals regimens. In order to achieve HCV micro elimination within these high-risk populations, novel strategies to improve the cascade of care from diagnosis to treatment with direct-acting antivirals, complemented by behavioral change interventions, harm reduction services for people who inject drugs, civil society led advocacy and policies from the government, will be necessary.

Abstract
(1) Background: The World Health Organization adopted a strategy for the Global Health Sector on Viral Hepatitis in 2016, with the main objective of eliminating hepatitis C virus (HCV) by 2030. In this work, we aimed to evaluate the prevalence of HCV infection and risk factors in a Romanian village using population-based screening as part of the global C virus eradication program. (2) Methods: We conducted a prospective study from March 2019 to February 2020, based on a strategy as part of a project designed to educate, screen, treat and eliminate HCV infection in all adults in a village located in Northeastern Romania. (3) Results: In total, 3507 subjects were invited to be screened by rapid diagnostic orientation tests (RDOT). Overall, 2945 (84%) subjects were tested, out of whom 78 (2.64%) were found to have positive HCV antibodies and were scheduled for further evaluation in a tertiary center of gastroenterology/hepatology in order to be linked to care. In total, 66 (85%) subjects presented for evaluation and 55 (83%) had detectable HCV RNA. Of these, 54 (98%) completed antiviral treatment and 53 (99%) obtained a sustained virological response. (4) Conclusions: The elimination of hepatitis C worldwide has a higher chance of success if micro-elimination strategies based on mass screening are adopted.

Abstract
Despite the availability of highly effective and well-tolerated direct-acting antivirals, not all patients with chronic hepatitis C virus infection receive treatment. This retrospective, multi-centre, noninterventional, case-control study identified patients with chronic hepatitis C virus infection initiating (control) or not initiating (case) treatment at 43 sites in Germany from September 2017 to June 2018. It aimed to compare characteristics of the two patient populations and to identify factors involved in patient/physician decision to initiate/not initiate chronic hepatitis C virus treatment, with a particular focus on historical barriers. Overall, 793 patients were identified: 573 (72%) who received treatment and 220 (28%) who did not. In 42% of patients, the reason for not initiating treatment was patient wish, particularly due to fear of treatment (17%) or adverse events (13%). Other frequently observed reasons for not initiating treatment were in accordance with known historical barriers for physicians to initiate therapy, including perceived or expected lack of compliance (14.5%), high patient age (10.9%), comorbidities (15.0%), alcohol abuse (9.1%), hard drug use (7.7%), and opioid substitution therapy (4.5%). Patient wish against therapy was also a frequently reported reason for not initiating treatment in the postponed (35.2%) and not planned (47.0%) subgroups; of note, known historical factors were also common reasons for postponing treatment. Real-world and clinical trial evidence is accumulating, which suggests that such historical barriers do not negatively impact treatment effectiveness. Improved education is key to facilitate progress towards the World Health Organization target of eliminating viral hepatitis as a major public health threat by 2030.
