Abstract
BACKGROUND AND OBJECTIVE Recent advances in hepatitis C virus (HCV) diagnostic testing methods allow for a one-stop simplified 'test and cure' approach. The cost effectiveness of incorporating this simplified approach into HCV screening in Iraq remains uncertain. This study aimed to compare the cost effectiveness of different HCV testing and diagnostic approaches, and screening strategies in Iraq from a health service perspective. METHODS A cost-effectiveness analysis was undertaken using a hybrid model comprising a screening decision tree linked to a lifetime Markov model to estimate outcomes in HCV-infected people. Cost and utility estimates were sourced from the published literature and expert guidance provided by clinicians and policy makers in Iraq. Cost estimates were reported in 2019 USD or 2019 Iraqi Dinar and both costs and benefits were discounted at 3.5% annually. RESULTS Strategies using a simplified approach were found to be cost saving in addition to improving patient outcomes when compared with a standard testing and diagnostic approach. When considering risk-based screening, a simplified approach was associated with a total cost saving of Iraqi Dinar 4375 billion (USD 3.7 billion) and per patient life-year and quality-adjusted life-year gains of 0.30 and 0.55, compared with a standard approach. Benefits and cost savings were driven by a 32.2% and 23.6% reduction in the incidence of cirrhosis and hepatocellular carcinoma, respectively. Estimated benefits and cost savings increased under total population screening. All screening and testing and diagnostic approaches were cost effective compared with a no screening scenario. CONCLUSIONS Improvements in the detection of HCV combined with a simplified one-stop testing and diagnostic approach represents an opportunity to reduce the burden of HCV in Iraq and may play a significant role in meeting World Health Organisation HCV elimination targets.

Abstract
Hepatitis C virus is a global public health threat, affecting 71 million people worldwide. Increasing recognition of the impact of this epidemic and recent advances in biomedical and technical approaches to hepatitis C prevention and cure have provided impetus for the World Health Organization (WHO) to call for global elimination of hepatitis C as a public health threat by 2030. This work reviews the feasibility of hepatitis C elimination and pathways to overcome existing and potential future barriers to elimination. Drawing on cost-effectiveness modeling and providing examples of successful implementation efforts across the globe, we highlight the resources and strategies needed to achieve hepatitis C elimination. A timely, multipronged response is required if the 2030 WHO elimination targets are to be achieved. Importantly, achieving hepatitis C elimination will also benefit the community well beyond 2030.

Genetic variation on the NFKB1 genes associates with the outcomes of HCV infection among Chinese Han population. INFECTION GENETICS AND EVOLUTION 2018; 65:210-215. [PMID: 30056167 DOI: 10.1016/j.meegid.2018.07.031] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/23/2018] [Revised: 07/23/2018] [Accepted: 07/24/2018] [Indexed: 12/12/2022]
Abstract
AIM To investigate whether nuclear factor-kappa B1 (NFKB1) gene polymorphisms are associated with the outcomes of hepatitis C virus (HCV) infection in a Chinese high-risk population. METHODS In this case-control study, 984 HCV-uninfected controls, 221 infected individuals with spontaneous HCV clearance, and 456 with persistent HCV infection were enrolled. Rs28362491 and rs72696119 were genotyped using the ABI TaqMan allelic discrimination assay. The functional annotation of the identified single nucleotide polymorphisms (SNPs) were further evaluated by bioinformatics analysis. RESULTS Significant differences were observed among the three groups (P < 0.001) in terms of the frequency of rs28362491 SNP. In logistic regression analysis, rs28362491-ATTG deleted (D) was associated with a significantly increased risk of HCV infection compared to the major-type rs28362491-ATTG inserted (I) (dominant model: adjusted OR = 1.332, 95% CI = 1.059-1.674, P = 0.014; additive model: adjusted OR = 1.181, 95% CI = 1.021-1.367, P = 0.025), after adjusting for age, gender, and route of infection. Based on the in silico prediction, the RegulomeDB score for SNP rs28362491 was 3a, indicating that it can potentially regulate the transcription and expression of NFKB1 gene. CONCLUSION NFKB1 rs28362491-D allele was functionally associated with the increased risk of susceptibility to HCV infection in the Chinese Han population.

Abstract
Aim: To evaluate the cost-effectiveness of the novel all-oral direct-acting antiviral regimen daclatasvir + asunaprevir (DUAL), versus interferon-based regimens for the treatment of chronic hepatitis C virus genotype 1b infection. Methods: Inputs for a lifetime Markov model were sourced from clinical trials and published literature. Outputs include disease management costs, life expectancy, quality-adjusted life-years and cost-effectiveness. Sensitivity analyses assessed the drivers of cost-effectiveness and sustained virologic response thresholds at which DUAL is cost-saving. Results: DUAL was associated with discounted incremental quality-adjusted life-years of 1.29-3.85 and incremental life-years of 0.85-2.59 per patient, with discounted lifetime cost savings of USD$1415-8525. Associated sustained virologic response rates could fall to 45.1-84.8%, while remaining dominant. Conclusion: Treatment with DUAL provides significant clinical benefit, while accruing lower lifetime costs.

MDM Policy Pract 2018; 3:2381468318776634. [PMID: 30288448 PMCID: PMC6157435 DOI: 10.1177/2381468318776634] [Citation(s) in RCA: 22] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2018] [Accepted: 04/20/2018] [Indexed: 12/15/2022] Open
Abstract
The World Health Organization HCV Guideline Development Group is considering a "treat all" recommendation for persons infected with hepatitis C virus (HCV). We reviewed the model-based evidence of cost-effectiveness and population health impacts comparing expanded treatment policies to more limited treatment access policies, focusing primarily on evaluations of all-oral directly acting antivirals published after 2012. Searching PubMed, we identified 2,917 unique titles. Sequentially reviewing titles and abstracts identified 226 potentially relevant articles for full-text review. Sixty-nine articles met all inclusion criteria-42 cost-effectiveness analyses and 30 models of population-health impacts, with 3 articles presenting both types of analysis. Cost-effectiveness studies for many countries concluded that expanding treatment to people with mild liver fibrosis, who inject drugs (PWID), or who are incarcerated is generally cost-effective compared to more restrictive treatment access policies at country-specific prices. For certain patient subpopulations in some countries-for example, elderly individuals without fibrosis-treatment is only cost-effective at lower prices. A frequent limitation is the omission of benefits and consequences of HCV transmission (i.e., treatment as prevention; risks of reinfection), which may underestimate or overestimate the cost-effectiveness of a "treat all" policy. Epidemiologic modeling studies project that through a combination of prevention, aggressive screening and diagnosis, and prompt treatment for all fibrosis stages, it may be possible to virtually eliminate HCV in many countries. Studies show that if resources are not available to diagnose and treat all HCV-infected individuals, treatment prioritization may be needed, with alternative prioritization strategies resulting in tradeoffs between reducing mortality or reducing incidence. Notably, because most new HCV infections are among PWID in many settings, HCV elimination requires unrestricted treatment access combined with injection transmission disruption strategies. The model-based evidence suggests that a properly constructed strategy that substantially expands HCV treatment could achieve cost-effective improvements in population health in many countries.

Abstract
BACKGROUND Hepatitis C virus (HCV) is a common cause of cirrhosis, leading to increased morbidity and mortality. Treatment of the underlying etiology has been shown to improve fibrosis and cirrhosis. AIM We sought to evaluate the impact of a sustained virologic response on liver chemistries, model for end stage liver disease (MELD) score, Child-Pugh-Turcotte score (CPT), and fibrosis 4 score (FIB4) in patients with liver cirrhosis secondary to HCV with portal hypertension, with or without decompensation. METHODS Patients with HCV seen in our transplant clinic between June 2013 and September 2015 were identified using ICD-9 code 573.3. Charts were reviewed retrospectively. RESULTS We collected data from 92 patients with a mean pretreatment MELD score of 9.16±2.98. The most common genotype was Ia, n=79 (86%). The mean duration of follow-up was 7.52±2.25 months. Transaminitis improved significantly at follow-up versus pretreatment [mean aspartate transaminase from 81.2±62.9 to 32.4±12.0 (P<0.0001); alanine transaminase 74.7±77.8 to 27.7±19.4 (P<0.0001)]. Albumin, bilirubin, and α-fetoprotein improved significantly. MELD scores improved in patients with pretreatment scores greater than 10 (P<0.0003), but not in patients with pretreatment scores less than 10 (P=0.501). The CPT score decreased from 6.1±0.9 to 5.8±0.9 (P<0.0024). The FIB4 score improved significantly in patients with baseline FIB4 more than 3.24, but not with higher baseline FIB4. CONCLUSION Use of direct antivirals in patients with decompensated cirrhosis because of HCV leads to improved MELD, FIB4, and CPT scores.

Abstract
Background and Aims This study aims to investigate the cost-effectiveness of a one-time hepatitis C virus (HCV) screening and treatment program in South Korea where hepatitis B virus (HBV) prevails, in people aged 40–70, compared to current practice (no screening). Methods A published Markov model was used in conjunction with a screening and treatment decision tree to model patient cohorts, aged 40–49, 50–59 and 60–69 years, distributed across chronic hepatitis C (CHC) and compensated cirrhosis (CC) health states (82.5% and 17.5%, respectively). Based on a published seroepidemiology study, HCV prevalence was estimated at 0.60%, 0.80% and 1.53%, respectively. An estimated 71.7% of the population was screened. Post-diagnosis, 39.4% of patients were treated with a newly available all-oral direct-acting antiviral (DAA) regimen over 5 years. Published rates of sustained virologic response, disease management costs, transition rates and utilities were utilised. Results Screening resulted in the identification of 43,635 previously undiagnosed patients across all cohorts. One-time HCV screening and treatment was estimated to be cost-effective across all cohorts; predicted incremental cost-effectiveness ratios ranged from $5,714 to $8,889 per quality-adjusted life year gained. Incremental costs associated with screening, treatment and disease management ranged from $156.47 to $181.85 million USD; lifetime costs-offsets associated with the avoidance of end stage liver disease complications ranged from $51.47 to $57.48 million USD. Conclusions One-time HCV screening and treatment in South Korean people aged 40–70 is likely to be highly cost-effective compared to the current practice of no screening.
