2019 February Hepatitis Newsletters: Finding Support

Valentine's Day is almost here, either you love it or hate, right? Me. Hate it. In any event, while you're waiting for either flowers, candy, diamonds or a sandwich, sit back and read this month's viral hepatitis newsletters, written by inspiring individuals that spread hope and love all year long.

Finding Support
Finding support online can be extremely useful when you're faced with decisions about HCV treatment or care. But remember folks, a support site, forum, or blog, should offer only personal experiences, and support, not medical advice. Understand any information you receive about HCV treatment, liver health or medications doesn't come from medical professionals and is not meant to replace your professional care. With that said, I highly suggest you check out the following support forums and my fav Facebook page.

Karen Hoyt's Facebook Page - Happy Valentine's Day!
Visiting Karen's Facebook page is like taking a class without leaving home. Karen covers it all, from tips on liver health, creating a well-balanced meal, to her own journey living with cirrhosis, liver cancer, and the emotional ups and downs of a lifesaving liver transplant.

Technology Drives Better HCV Outcomes

Gastroenterology & Endoscopy News

Technology Drives Better HCV Outcomes 

Boston—Using ingestible sensors, mobile apps, dashboards and other high-tech tools, pharmacists are working with providers to improve adherence rates among patients with hepatitis C virus, according to two studies presented at the 2018 Academy of Managed Care Pharmacy’s Managed Care & Specialty Pharmacy Meeting.

With an electronic clinical dashboard, pharmacists are able to help manage 2,400 patients in the HCV program created by Kaiser Permanente Washington, in Seattle. Specialty and clinical pharmacists collaborate with providers and patients to provide treatment that optimizes outcomes and reduces waste. Pharmacists with expertise in HCV work with providers to choose optimal regimens; monitor clinical response, laboratory results and adverse effects; and adjust therapy as needed. The specialty pharmacy dispenses medications and helps obtain financial support for patients. The pharmacists track treatment completion rates and sustained virologic response 12 weeks (SVR-12) after completion of treatment through the dashboard (abstract B10).

Psychological relief is the most important benefit of a hepatitis C cure for patients

Psychological relief is the most important benefit of a hepatitis C cure for patients
Roger Pebody Published: 13 September 2018
When asked to describe what their hepatitis C cure meant to them, Australians who had recently completed treatment emphasised an improved sense of psychological wellbeing, according to a qualitative study recently published in Hepatology, Medicine and Policy.

They described their relief about no longer fearing the development of liver disease or cancer, or of infecting others. Interviewees who had a history of injecting drug use understood their cure as a way to break the connection with their past.

Jacqueline Richmond of La Trobe University and colleagues recruited people who had achieved a sustained virological response 12 weeks after completing treatment (SVR12) in order to be interviewed about their experience of treatment and of cure. All participants were recruited from clinics in Melbourne, Australia between October 2016 and April 2017. The interviews were conducted during an early phase of the roll-out of direct acting antiviral (DAA) treatment in Australia; those interviewed are therefore likely to be ‘early adopters’ who may have been more motivated and enthusiastic than some other people who are eligible for treatment.

January 17, 2018

Despite a revolutionary opportunity to end the global HCV epidemic, there clearly is a need for a concerted effort to help many more people benefit from curative therapy. It is evident that we, as healthcare providers, must step up our efforts to reach and treat patients who can benefit from DAA therapy. Only 9% of the 4 million Americans living with HCV have been successfully treated.

What’s Important to the Patient? Informational Needs of Patients Making Decisions About Hepatitis C Treatment

Full Text

Background and Objectives

Multiple treatment options with direct-acting antivirals are now available for hepatitis C virus (HCV). Study aims were to understand (1) the informational topics patients want to have to make informed treatment decisions; (2) the importance patients place on each topic; and (3) the topics patients prioritize as most important.


We used a mixed-methods study of two samples recruited from an academic liver center. Participants were not currently on treatment. Sample I (n = 45) free listed all informational topics deemed important to decision making. Raw responses were coded into several broad and subcategories. Sample II (n = 38) rated the importance of the subcategories from Sample I and ranked their highest priorities on two surveys, one containing topics for which sufficient research existed to inform patients (‘static’), and the other containing topics that would require additional research.


The topics listed by Sample I fell into six broad categories with 17 total subcategories. The most oft-cited informational topics were harms of treatment (100%), treatment benefits (62%), and treatment regimen details (84%). Sample II rated 16 of 17 subcategories as “pretty important’ or “extremely important”. Sample II prioritized (1) viral cure, (2) long-term survival, and (3) side effects on the survey of topics requiring additional research, and (1) liver disease, (2) lifestyle changes, and (3) medication details on the second survey of the most important static topics patients needed.


Patients weighed several informational topics to make an informed decision about HCV treatment. These findings lay the groundwork for future patient-centered outcomes research in HCV and patient-provider communication to enhance patients’ informed decision making regarding direct-acting antiviral treatment options.

Key Points for Decision Makers
Patients contemplating hepatitis C virus treatment want a great deal of information to make informed treatment decisions.

The most commonly cited informational topics included treatment harms such as side effects, treatment benefits such as viral cure, details of the treatment regimen, details about the virus, liver disease, and the risks of not receiving treatment.

The most important topics that require additional investigation were information about viral cure, long-term survival, and treatment side effects. The most important topics for which we have sufficient information that can be shared with patients include liver disease, lifestyle changes needed for treatment, and details about the medications and treatment protocol.

Identifying Patients With Chronic Hepatitis C in Need of Early Treatment and Intensive Monitoring

Alimentary Pharmacology & Therapeutics
Systematic Review

Identifying Patients With Chronic Hepatitis C in Need of Early Treatment and Intensive
Monitoring Predictors and Predictive Models of Disease Progression

M. A. Konerman, S. Yapali, A. S. Lok

Aliment Pharmacol Ther. 2014;40(8):863-879.

Background Advances in hepatitis C therapies have led to increasing numbers of patients seeking treatment. As a result, logistical and financial concerns regarding how treatment can be provided to all patients with chronic hepatitis C (CHC) have emerged.
Aim To evaluate predictors and predictive models of histological progression and clinical outcomes for patients with CHC.
Methods MEDLINE via PubMed, EMBASE, Web of Science and Scopus were searched for studies published between January 2003 and June 2014. Two authors independently reviewed articles to select eligible studies and performed data abstraction.
Results Twenty-nine studies representing 5817 patients from 20 unique cohorts were included. The outcome incidence rates were widely variable: 16–61% during median follow-up of 2.5–10 years for fibrosis progression; 13–40% over 2.3–14.4 years for hepatic decompensation and 8–47% over 3.9–14.4 years for overall mortality. Multivariate analyses showed that baseline steatosis and baseline fibrosis score were the most consistent predictors of fibrosis progression (significant in 6/21 and 5/21, studies, respectively) while baseline platelet count (significant in 6/13 studies), aspartate and alanine aminotransferase (AST/ALT) ratio, albumin, bilirubin and age (each significant in 4/13 studies) were the most consistent predictors of clinical outcomes. Five studies developed predictive models but none were externally validated.
Conclusions Our review identified the variables that most consistently predict outcomes of patients with chronic hepatitis C allowing the application of risk based approaches to identify patients in need of early treatment and intensive monitoring. This approach maximises effective use of resources and costly new direct-acting anti-viral agents.


With the introduction of more efficacious and less toxic drugs, treatment of chronic hepatitis C (CHC) is evolving at a rapid pace. The two new direct-acting anti-viral agents (DAA), simeprevir and sofosbuvir, increase rates of sustained virological response (SVR) with shorter treatment durations compared to prior therapies.[1,2] Along with advances in therapy, there has been a focus on the public health impact of CHC. The Centers for Disease Control and Prevention, the Institute of Medicine, and the United States Preventive Services Task Force, have prioritised hepatitis C awareness, screening and diagnosis.[3–5] Treatment is also being advocated as a means to prevent hepatitis C virus (HCV) infection. As a result of these processes, the pool of potential treatment candidates is expected to balloon. This has caused the conundrum in HCV treatment to shift from 'Can we improve the efficacy and tolerability of HCV treatment?' to 'Can we afford to treat all patients with CHC?'

At the core of the dilemma is the high cost of these new drugs. The estimated wholesale price of a 12-week course of sofosbuvir in the United States (US) is $84 000 and of simeprevir $66 000.[6,7] These staggering costs exclude retail markup, and associated cost of pegylated interferon (IFN), ribavirin, physician visits and laboratory tests. While these new treatment regimens have SVR rates of 80–90%, and SVR has been shown to decrease cirrhosis complications, hepatocellular carcinoma (HCC) and liver-related mortality, even resource-replete countries like the US cannot afford to treat all those who are infected.[1,2,8] The logistical and financial barriers are much higher in resource-limited countries, many of which have higher prevalence of HCV infection than western countries. Clinicians and health policy makers will need to determine an optimal yet practical approach to provide these highly efficacious, but extremely costly therapies to this burgeoning patient population.

One solution is to adopt a risk-stratified approach that targets therapy to those at the greatest risk of disease progression. There have been many studies investigating risk factors for disease progression in patients with CHC but few have employed a longitudinal study design in generalisable patient populations using data that are routinely available in clinical practice. Results of the existing studies have also not been systematically summarised in a single document. Therefore, we performed a systematic review of the literature to (i) identify factors predictive of disease progression (fibrosis progression and clinical outcomes) in patients with CHC and (ii) assess existing predictive models.

Data Sources and Search Strategy
We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) recommendations in conducting this systematic review.[9] With the assistance of a medical research librarian, we performed serial literature searches for English and non-English articles. MEDLINE (via PubMed), EMBASE, Web of Science and Scopus were searched using the following keywords: 'cirrhosis' or 'liver cirrhosis' or 'fibrosis', 'hepatitis C' or 'hepatitis C, chronic' or 'chronic hepatitis C', 'disease progression' or 'progression' or 'decompensation'. Boolean operators and medical subject heading terms as well as other controlled vocabulary were used to enhance electronic searches. An example of specific search strategy details is shown in Table S1

All human subject studies published in full-text or abstract were eligible for inclusion. The search was limited to publications from 2003 to 2014 as this 10-year period contained the most contemporary and relevant data with respect to treatment and current practice. Additional studies of interest were identified by hand searches of bibliographies and cited reference tracking and consultation with clinical experts on the topic. The initial search was performed in October 2013 and the search was last updated on 2 June 2014.

Study Eligibility and Selection Criteria
Two authors (M.A.K. and A.S.L.) sequentially determined study eligibility. Studies were initially screened by the first author; decisions about study inclusion were made independently by both authors (M.A.K and A.S.L). Differences in opinion regarding study inclusion were resolved through consensus. Studies were included if they: (i) included human studies with participants 18 years of age or older; (ii) systematically evaluated predictors of fibrosis progression and/or clinical outcomes for patients with CHC; and (iii) used a longitudinal cohort study design. We focused on studies of untreated patients but also included studies with a mix of treated and untreated patients provided that <20% of the study population achieved SVR and results were stratified by treatment outcomes. For studies evaluating predictors of fibrosis progression, we selected studies only when paired biopsy was used to assess progression.

We excluded studies that enrolled (i) patients co-infected with hepatitis B (HBV) or human immunodeficiency virus (HIV); (ii) patients with additional causes of chronic liver disease; (iii) patients with prior liver transplantation and (iv) specific groups of patients (e.g. thalassaemia patients) only. These patient populations were excluded because they likely have different rates and risk factors for disease progression compared to the general population of patients with CHC. In addition, studies that evaluated HCC as the only outcome of interest were excluded as we were interested in broad clinical outcomes for patients with CHC, and predictors of HCC development alone may not be the same as predictors of disease progression in CHC in general. Lastly, studies that focused on predictors that are not readily available clinically (e.g. genetic or other serum markers for which commercial assays are not available, and experimental imaging techniques) were excluded given that they would not be relevant to current clinical practice.

Definition of Variables and Outcomes
Patients with CHC were defined as those with detectable HCV ribonucleic acid (RNA). We were interested in two outcomes: histological progression and clinical progression. The definition of histological progression was an increase of ≥1 METAVIR (range 0–4) or Ishak (range 0–6) fibrosis stage on follow-up liver biopsy. The definition of clinical progression encompassed the progression from compensated to decompensated cirrhosis, and liver-related or overall mortality. The definition of compensated cirrhosis was based on histology when available (Ishak fibrosis score ≥5 or METAVIR 4) or on the combined results of other noninvasive testing including laboratory tests and imaging. Decompensated cirrhosis was defined by the presence of any of the following: ascites, spontaneous bacterial peritonitis (SBP), variceal bleeding or hepatic encephalopathy (HE). The presence of HCC as defined by histology or American Association for Study of Liver Diseases radiological criteria was variably included as a clinical outcome.[10]

Data Abstraction and Validity Assessment

Data from eligible studies were abstracted by two authors (M.A.K. and S.Y.) using a standardised template adapted from the Cochrane Collaboration.[11] For all studies, we recorded: study design, sample size, patient population characteristics, duration of follow-up, predictor variables studied, outcomes measured, criteria used to define these outcomes and measures of association/predictiveness of risk for these outcomes. We accepted the outcome definitions as stated by each study without independently validating or reviewing their data. Study authors were directly contacted for additional, unpublished data.

Assessment of Risk of Bias and Study Quality
Two authors (M.A.K and S.Y.) independently assessed the risk of study bias and study quality. Since all the included studies were nonrandomised cohort studies, the Newcastle-Ottawa scale was used to judge study quality as recommended by the Cochrane Collaboration.[12] This scale uses a star system to assess the quality of a study based on three domains: selection of the study population, comparability of the study groups and method of outcomes assessment. For our review, given that no study had a comparison group, we excluded comparability components of the scale across all studies. Studies which received stars in every domain were assessed as being of high quality.

Data Synthesis and Analysis
Given the substantial variation in the design, methods and inclusion/exclusion criteria within our included studies, meta-analysis was not performed. Two authors (M.A.K. and S.Y.) qualitatively synthesised the results of the included studies, focusing on the risk factors evaluated and their independent predictiveness in terms of the outcomes measured and patient populations studied. Studies were categorised according to the outcome of interest: predictors of histological progression, predictors of clinical outcomes or studies investigating both clinical and histological outcomes. All authors had access to the study data and had reviewed and approved the final manuscript.

Studies Included in the Systematic Review
After removal of duplicate entries, 2257 unique articles were identified by our systematic literature search (Figure 1). On the basis of abstract review, 69 were selected for full-text review. Two study authors classified 29 articles as meeting the predefined criteria for analysis. In total, these 29 studies included 5817 unique patients from 20 separate patient cohorts. Sixteen of these studies investigated predictors of histological progression, eight studies evaluated predictors of clinical outcomes, and the remaining five studies investigated both histological and clinical outcomes.[13–41] Fourteen studies included treatment-naïve patients only, five included both treatment-naïve and treatment-experienced patients, eight included treatment-experienced patients only, and two studies did not describe the treatment status of the patients. We contacted four authors to obtain additional unpublished data.

Flow diagram of studies included in the systematic review. aMany studies met multiple exclusion criteria. Each study was coded under a single criterion only. bIncludes animal models, paediatric populations, patients who had previously undergone liver transplant, patients with chronic liver disease other than HCV monoinfection, evaluation of only specific subsets of populations with CHC. cIncludes studies that were descriptive papers only, studies that did not specifically evaluate for predictors of histological or clinical progression, and studies that evaluated predictors that are not readily clinically available. dIncludes studies that focused on risk factors for the development of HCC only, and studies where some patients achieved SVR and the results were not stratified based on response to treatment.

Characteristics of Studies on Histological Progression
A total of 21 studies evaluated predictors of histological progression. The studies included populations from Europe (n = 10), Asia (n = 2), and North (n = 8) and South America (n = 1). Only one study was prospective with the remaining 20 being retrospective analyses of previously collected data. The sample size for included studies varied (range 36–622 patients) with the majority having <200 patients (n = 14). A number of studies had overlapping cohorts. Four studies were derived from the Hepatitis C Anti-viral Long-term Treatment Against Cirrhosis (HALT-C) cohort, a US multi-centre randomised controlled trial to evaluate the safety and efficacy of low dose pegylated IFN in CHC patients with advanced fibrosis who failed to respond to prior IFN therapy. Four other pairs of studies drew from the same cohort of patients.[17,21,25,29,33,35,38,41] These studies were included in the review despite overlapping cohorts given differences in predictors examined, outcomes evaluated and criteria for selection of subsets of patients analysed within the overall larger cohort. The average duration of follow-up ranged from a median of 2.5–10 years.

The studies had varied inclusion and exclusion criteria as detailed in Table 1. Among the non-HALT-C studies, 11 studies had explicit requirements for baseline Ishak/METAVIR fibrosis stage. Five studies required minimal or no fibrosis at baseline and the remaining six studies required lack of cirrhosis on initial biopsy. Only 14 studies described criteria used to determine adequacy of biopsy specimens. The majority of the studies had a single pathologist blinded to clinical data score the biopsies while the HALT-C study had a panel of pathologists review the biopsies and consensus staging was recorded. Exclusionary alcohol intake was described in nine studies though the cut-off amounts and methods for ascertaining alcohol intake varied across the studies. The studies were predominately comprised of male patients in their late 30s to early 50s.

Characteristics of Studies of Clinical Outcomes
A total of 13 studies evaluated predictors of clinical outcomes. Six studies were conducted in the US (including 5 HALT-C studies), five in Europe and two in Asia. Only two studies were prospective with the remaining 11 being retrospective analyses. Sample size in each study varied from 52 to 1457 patients. Apart from the HALT-C studies, there was only one additional overlapping cohort.[36,37] The average duration of follow-up ranged from a median of 2.3 to a maximum of 14.4 years. Compared to studies on histological progression, the studies on clinical outcomes consisted of patients who were older, had more advanced fibrosis at baseline, and were more likely to be treatment experienced.

Incidence of Histological Progression
A summary of the specific outcomes evaluated and incidence of these outcomes in each study is displayed in Table 2, Table 3 and Table 4. For studies where the outcome was defined as ≥1 fibrosis stage increase on follow-up biopsy (n = 13), the incidence of that outcome ranged from 21–61% over a range of follow-up of 2.5–10 years.[14,16,18,21,25,28–33,35,41] Studies applying a stricter definition of fibrosis progression (≥2 stage increase on follow-up biopsy, n = 3) had less variability in range of incidence of outcome, reporting 22–34% over a range of follow-up of 3.5–5.8 years.[13,23,26] Studies with higher rates of fibrosis progression tended to have longer follow-up durations (>6 years), though there were several studies with follow-up of ≥6 years that had low rates of fibrosis progression. No identifiable differences in patient characteristics between studies with high vs. low incidence of fibrosis progression were noted.

Incidence of Clinical Progression
Studies assessing risk factors for clinical progression (n = 13) included several distinct outcomes. Four studies evaluating progression from compensated to decompensated cirrhosis reported an incidence between 13% and 40% over a range of follow-up of 2.3–14.4 years.[15,24,31,34] No clear pattern was identified between length of follow-up or patient characteristics and rate of outcomes. Notably, the definition of decompensation varied across studies. Four studies evaluating the incidence of overall mortality reported incidences between 8% and 47%. The range of follow-up for these studies was 3.9–14.4 years, with a higher rate of outcomes reported in studies with longer duration of follow-up.[15,27,39,40] The remaining studies used an aggregate outcome encompassing a broad range of clinical end points including decompensation, increase in Child–Turcotte–Pugh score, development of HCC, liver transplant and liver related as well as overall mortality. The reported incidence of this aggregate outcome was 13–31% over a range of follow-up of 3.5–6.3 years.[19,20,23,26,36,37]

Predictors of Histological Progression
A detailed list of the predictors evaluated and the results of univariate analysis is provided in Tables S3–S5 For each study, the predictor variables were categorised as follows: (i) baseline clinical characteristics including demographics and relevant co-morbidities; (ii) baseline laboratory results; (iii) baseline histological features or (iv) longitudinal laboratory and histology results.
All studies investigating predictors of histological progression evaluated baseline clinical characteristics, baseline laboratory results and baseline histology results except for Tamaki et al. who did not evaluate baseline histological features.[38] Only half of the studies evaluated longitudinal variables which were predominantly serial aminotransferase levels. Longitudinal biopsy results such as changes in steatosis score or histological activity index (HAI) were assessed in only five studies.[16,22,28–30] The predictors that were most consistently evaluated are listed in Figure 2a. The most common clinical characteristics assessed were age, gender, HCV genotype, alcohol intake, body mass index (BMI) and biopsy interval, and the most common laboratory values evaluated were platelet count and ALT levels. Baseline histological features were also frequently investigated predictors and were included in >70% of studies.

Multivariable analysis was performed in all but two studies.[19,31] Variables found to be independently predictive of histological progression are listed in Table 2 and Table 4. Among all the variables assessed, baseline steatosis was most consistently reported as independently predictive of subsequent fibrosis progression (significant on multivariate analysis in 6 of 21 studies) with an odds ratio (OR) [(95% confidence interval (CI)] of 4.8 (1.3–18.3) to 14.3 (2.1–111.1).[12,16,18,20,24,27] Notably, one study found that effect of baseline steatosis on fibrosis progression was dependent on baseline fibrosis stage.[20] Baseline Ishak/METAVIR fibrosis stage was the next most consistently identified independent predictor of histological progression (significant on multivariable analyses in five of 21 studies).[20,25,30,33,35] Only one of these studies reported the effect size, with adjusted relative risk of 1.93 (95% CI 1.3–9.0).[35] Figure 2a depicts the number of studies in which individual variables were significantly or not significantly predictive of histological progression on multivariate analyses.

Predictors of Clinical Outcomes
All 13 studies examining predictors of clinical outcomes included baseline clinical characteristics and laboratory results (Tables S4 and S5 Baseline histology was assessed in only eight studies though biopsies were performed in every study. Only three studies incorporated longitudinal data which consisted of serial laboratory values only.[23,24,36] The predictors that were most consistently evaluated are listed in Figure 2B. The most common clinical characteristics assessed were age, gender and BMI; the most common laboratory values evaluated were platelet count and ALT level.

Multivariable analysis was performed in all but two studies.[19,31] The variables found to be independently predictive of clinical progression are listed in Table 3 and Table 4. Among the variables assessed, baseline platelet count was the most consistent independent predictor of clinical outcomes (significant on multivariate analysis in six of 13 studies) followed by age, baseline AST/ALT ratio, albumin and bilirubin (each significant in four studies).[15,24,26,36,37,39] Figure 2B depicts the number of studies in which individual variables were significantly or not significantly predictive of clinical outcomes in multivariate analyses.

Mathematical Prediction Models

Five studies provided prediction models, three for fibrosis progression and four for clinical outcomes (Table S6[23,26,32,39,40] Four of the models were derived from the HALT-C study. All the prediction models are primarily comprised of baseline laboratory results. Only one of the models incorporated longitudinal data. None of the models had been validated in external CHC cohorts and only two models reported the associated area under the receiver operating characteristic curve.[23,40]

Quality Assessment and Risk of Bias
Studies evaluating predictors of histological progression were of varying quality, whereas studies investigating predictors of clinical outcomes or studies investigating combined outcomes were all of high quality except for one study.[31] Six studies on histological progression included a small number of patients with advanced fibrosis or cirrhosis on initial biopsy who were not able to progress according to the author's definition.[17][18, 25, 28, 33, 38] Two studies evaluated select cohorts (Levine et al. evaluated untreated Irish women who acquired HCV infection during pregnancy only, and Livingston et al. evaluated only treatment naïve Alaska Native and American Indian persons) and were scored as having limited representativeness.[30,31] The remaining studies were scored as being at least somewhat representative of the average patient with CHC in the community (Table S2

Although there is abundant literature on the topic of predictors of histological and clinical outcomes for patients with CHC, only 29 studies met our inclusion criteria which captured studies with a longitudinal study design in broad patient populations. Within the 29 studies included, the incidence of outcomes varied widely: 16–61% during a median follow-up of 2.5–10 years for fibrosis progression; 13–40% over 2.3–14.4 years for hepatic decompensation; and 8–47% over 3.9–14.4 years follow-up for overall mortality. The wide range in incidence of outcomes highlights the heterogeneity in patient population evaluated, stage of liver disease at enrollment, duration of follow-up, and definition of outcomes. Interestingly, higher rates of outcomes did not clearly correlate with longer durations of follow-up or more advanced disease at baseline across studies, pointing to more complex underlying interactions driving outcomes. Although the incidence data were not conducive to providing consensus outcome rates, we were able to identify risk factors that have most consistently been associated with outcomes of interest. Baseline steatosis and fibrosis score were the most consistent predictors of fibrosis progression and baseline platelet count, AST/ALT ratio, albumin, bilirubin and patient age were the most consistent predictors of clinical outcomes.
The variables identified as being most predictive of outcomes were not unexpectedly markers of more advanced liver disease. Though the overall finding that patients with more advanced disease are at higher risk for adverse outcomes is not novel, our study is the first to systematically identify the specific risk factors from among the many markers of advanced liver disease that portends worse prognosis. For example, among the laboratory markers of more advanced liver disease, platelet count, bilirubin, albumin and AST/ALT ratio conveyed meaningful risk information whereas INR, AST, ALT and MELD score did not. Differences in study design made it difficult to identify clear cut-off values for each predictor apart from platelet count with values ≤150 000/uL consistently associated with worse prognosis. Furthermore, individual laboratory markers may be less reliable in predicting outcomes than panels of markers such as aspartate aminotransferase to platelet ratio index (APRI), FIB-4, Fibrotest and/or measurements of liver stiffness. The finding that patients with more advanced disease have greater risk of disease progression suggests there may be subsets of patients who are rapid progressors. Understanding whether some patients are destined to be rapid progressors and being able to identify these patients at an early stage will help target limited resources to treat those patients who will derive the most benefit. Though none of the existing predictive models have been externally validated, the model developed by Ghany and colleagues is most readily applicable in clinical practice as it is based on routinely available data and evaluates important liver-related clinical outcomes.[26]

Examining the results in more detail yielded several useful insights. First, the finding of steatosis as a predictor of outcomes highlights a potential modifiable risk factor associated with disease progression. This is particularly relevant given the evolving obesity epidemic. Our data suggest that patients may benefit from aggressive lifestyle interventions in addition to other standard of care treatment for patients with CHC. The prognostic information gained from baseline liver biopsy results suggests that liver biopsies not only provide information regarding current staging of liver disease but also useful prognostic information. As performance of liver biopsies continue to decline, evaluating whether noninvasive assessment of fibrosis and steatosis will provide the same prognostic information would be important. Though only one study included in our review used an additional modality to assess liver fibrosis in conjunction with biopsy, this study showed that liver stiffness measurements were associated with overall mortality.[40]

Our review also highlights several areas for improvement for future studies on predictors of disease progression in CHC. Analysis of the individual predictive value of each risk factor found that there was a notable lack of incorporation of longitudinal variables. In the few studies that did assess longitudinal data, these variables were usually restricted to laboratory values, predominantly AST and ALT levels. These models do not mirror clinical practice where assessments of risk of disease progression are based on the pattern of a patient's test results over time. Models restricted to only baseline data also cannot distinguish between patients with similar initial data but who go on to have distinct disease courses and outcomes. Future studies can also benefit from implementing standardised definitions and criteria for outcomes and employing a panel of investigators to adjudicate outcomes as the variability in definition of predictor and outcome variables was one of the biggest challenges.

There are other limitations to our review such as sample selection bias, sampling error and misclassification bias in studies requiring paired biopsies. In the majority of studies, biopsies were assessed by a single pathologist and criteria for adequacy of biopsies was described in only 14 of 21 studies. Finally, the variability in duration of follow-up impacts not only incidence rates of outcomes but also predictiveness of variables examined.

In summary, this systematic review demonstrated that while there is an abundance of literature on factors associated with histological and/or clinical progression in CHC, there is a lack of longitudinal studies of representative, untreated, well characterised patients followed for a sufficiently long duration to allow the development of simple prediction models. Despite the limitations inherent to the existing literature, we were able to identify specific risk factors that have been consistently identified as being independently predictive of disease progression. By selecting studies consisting of broad patient populations and those that evaluated routinely obtained clinical data, our findings can be generalised to and applied in many clinical settings. From a policy standpoint, we have highlighted that it is possible to identify patients at higher risk for adverse outcomes. Policies that target costly new HCV therapies to these patients who would derive the most benefit will maximise their cost effectiveness. The availability of risk prediction tools that can be applied in the clinic will help both physicians and patients decide whether to embark on HCV treatment now or to wait for more affordable treatment. These types of tools will be particularly important in resource-limited countries and must therefore be validated in broad patient populations.
