BACKGROUND & AIMS Pegylated interferon-based treatment is still the backbone of current hepatitis C therapy and is associated with bone marrow suppression and an increased risk of infections. The aim of this retrospective cohort study was to assess the risk of infections during interferon-based treatment among patients with chronic HCV infection and advanced hepatic fibrosis and its relation to treatment-induced neutropenia. METHODS This cohort study included all consecutive patients with chronic HCV infection and biopsy-proven bridging fibrosis or cirrhosis (Ishak 4-6) who started treatment between 1990 and 2003 in five large hepatology units in Europe and Canada. Neutrophil counts between 500/μL-749/μL and below 500/μL were considered as moderate and severe neutropenia, respectively. RESULTS This study included 723 interferon-based treatments, administered to 490 patients. In total, 113 infections were reported during 88 (12%) treatments, of which 24 (21%) were considered severe. Only one patient was found to have moderate neutropenia and three patients were found to have severe neutropenia at the visit before the infection. Three hundred and twelve (99.7%) visits with moderate neutropenia and 44 (93.6%) visits with severe neutropenia were not followed by an infection. Multivariable analysis showed that cirrhosis (OR 2.85, 95%CI 1.38-5.90, p=0.005) and severe neutropenia at the previous visit (OR 5.42, 95%CI 1.34-22.0, p=0.018) were associated with the occurrence of infection, while moderate neutropenia was not. Among a subgroup of patients treated with PegIFN, severe neutropenia was not significantly associated (OR 1.63, 95%CI 0.19-14.2, p=0.660). CONCLUSIONS In this large cohort of patients with bridging fibrosis and cirrhosis, infections during interferon-based therapy were generally mild. Severe interferon-induced neutropenia rarely occurred, but was associated with on-treatment infection. Moderate neutropenia was not associated with infection, suggesting that current dose reduction guidelines might be too strict.

Objective Reliable tools to predict long-term outcome among patients with well compensated advanced liver disease due to chronic HCV infection are lacking. Design Risk scores for mortality and for cirrhosis-related complications were constructed with Cox regression analysis in a derivation cohort and evaluated in a validation cohort, both including patients with chronic HCV infection and advanced fibrosis. Results In the derivation cohort, 100/405 patients died during a median 8.1 (IQR 5.7-11.1) years of follow-up. Multivariate Cox analyses showed age (HR=1.06, 95% CI 1.04 to 1.09, p10%, the observed 5-year mortality rates in the derivation cohort and validation cohort were 0.9% (95% CI 0.0 to 2.7) and 2.6% (95% CI 0.0 to 6.1), 8.1% (95% CI 1.8 to 14.4) and 8.0% (95% CI 1.3 to 14.7), 21.8% (95% CI 13.2 to 30.4) and 20.9% (95% CI 13.6 to 28.1), respectively (C statistic in validation cohort = 0.76, 95% CI 0.69 to 0.83). The risk score for cirrhosis-related complications also incorporated HCV genotype (C statistic = 0.80, 95% CI 0.76 to 0.83 in the derivation cohort; and 0.74, 95% CI 0.68 to 0.79 in the validation cohort). Conclusions Prognosis of patients with chronic HCV infection and compensated advanced liver disease can be accurately assessed with risk scores including readily available objective clinical parameters.

Objective: We aimed to identify those patients with hepatitis C virus who benefit most from prophylactic treatment with selective serotonin reuptake inhibitors (SSRIs) during antiviral therapy. Method: We performed post hoc analyses on a prospective randomized controlled trial (n = 79) of escitalopram versus placebo during antiviral therapy with pegylated interferon and ribavirin, conducted between August 2005 and June 2008. Our primary outcome measure was the association of baseline characteristics with the development of depression and/or depressive symptoms. Further, we studied effects of prophylactic escitalopram on depressive symptoms. Presence of a major depression was diagnosed using Mini-International Neuropsychiatric Interview (MINI), a short, structured interview used to diagnose DSM-IVTR and ICD-10 disorders. Depressive symptoms were monitored during treatment by using the depression scale of Symptom Checklist-90 (SCL-90), Montgomery-Asberg Depression Rating Scale (MADRS), and Beck Depression Inventory (BDI) at baseline and weeks 4, 12, and 24 of antiviral therapy. Results: Depression occurred in 14 patients receiving placebo and in 5 patients receiving escitalopram (Pearson chi(2), P = .01). Combination of history of depression and intravenous drug use was associated with depression (odds ratio = 12.60; 95% CI, 2.47-64.34; P < .01). Moreover, treatment with selective serotonin reuptake inhibitor compared to placebo was associated with a significant reduction in estimated mean depressive symptoms measured by SCL-90 (P = .03) and BDI (P = .048), but not with MADRS (P = .64). Conclusions: Patients infected by hepatitis C virus with a history of depression and intravenous drug use carry the highest risk to develop interferon-induced depression. In this subset of patients, prophylaxis with escitalopram results in the most substantial decrease of interferon-induced depressive symptoms on the SCL-90 depression scale and the BDI.

Chronic hepatitis C (CHC)-related cirrhosis is the leading indication for liver transplantation (LT). However, the recurrence of a hepatitis C virus (HCV) infection after transplantation is universal and is associated with worse outcomes. Fibrosing cholestatic hepatitis (FCH) is a particularly severe manifestation of a recurrent HCV infection and frequently results in graft failure and death. The identification of risk factors for FCH is important but has been limited by the low frequency of FCH. The interleukin-28B (IL-28B) genotype is important in an HCV infection: it is related to the clinical severity of an acute infection and may play a role in the development of FCH as well. Two hundred seventy-two consecutive LT cases for CHC were studied at a single institution. Consensus criteria were used to define an FCH cohort. The remainder of the study population served as a control group. The IL-28B genotype (at the rs12979860 locus) from both the donor and the recipient was determined, and other clinically relevant data were tabulated. A nonparametric statistical analysis was performed. Twelve cases of FCH were identified, and they were compared to a control group of 260 LT cases without FCH. A detailed analysis of clinical characteristics, including treatment responses and outcomes, was tabulated. FCH was associated with the earlier recurrence of HCV infections, higher HCV viral loads, and lower levels of immunosuppressive medications. There was a nonsignificant increase in recipient IL-28B non-CC genotypes in cases developing FCH. In conclusion, a high HCV viral load and earlier recurrence were identified as risk factors for FCH. It is still unclear what role immunosuppression plays in the pathogenesis of FCH and whether IL-28B polymorphisms constitute a risk factor. Collaborative studies with larger numbers of study subjects are needed in order to define these issues.

The IL28B genotype has been linked to sustained virological response (SVR) in hepatitis C virus (HCV). Its role on disease biology and progression is less clear. We characterized the effects of IL28B genotype on HCV recurrence, allograft histology, rate of SVR, and survival after liver transplantation (LT) in HCV.Consecutive patients who underwent LT with HCV were studied. The rs12979860 genotype from both the donor was and recipient was determined. Measured endpoints included histologic HCV recurrence (inflammatory grade and fibrosis stage), acute cellular rejection, SVR, retransplantation, and death.The study cohort comprised 272 consecutive LT in 255 patients. C-allele frequency was 56% in recipients and 70% in donors (P0.001). Recipient IL28B CC genotype was associated with lower alanine aminotransferase levels and viral load at recurrence and a lower frequency of F≥2 on liver biopsy at 1 year after LT, when compared with the non-CC genotype (P=0.012). The opposite was observed in LT with donor CC genotype (P=0.003). Both recipient and donor CC genotype favored SVR, and when the two of them occurred together, the SVR rate reached 90%. Survival analysis after 5.5 years of follow-up showed a higher rate of progression to cirrhosis (hazard ratio, 5.96; 95% confidence interval, 1.29-27.6), liver-related death, or retransplantation among liver transplant recipients with a CC genotype donor.The IL28B genotype is predictive not only of SVR but also of the histologic diagnosis of posttransplant hepatitis C, with donor CC genotype favoring inflammation and fibrosis, and adverse outcomes during long-term follow-up. A favorable effect of donor CC genotype is manifest only after antiviral therapy.

In the nontransplant setting diabetes mellitus is a risk factor for disease progression in patients with chronic hepatitis C virus (HCV) infection. The impact of early insulin resistance on the development of advanced fibrosis, even in the absence of clinically apparent diabetes mellitus, is not known. Our aim was to determine whether the Homeostasis Model Assessment of Insulin Resistance (HOMA-IR) can be used to identify insulin-resistant patients at risk for rapid fibrosis progression. Cohort study including patients transplanted for chronic HCV between January 1, 1995 and January 1, 2005. One hundred sixty patients were included; 25 patients (16%) were treated for diabetes mellitus and 36 patients (23%) were prediabetic, defined as HOMA-IR > 2.5. Multivariate Cox regression analysis showed that insulin resistance (hazard ratio (HR) 2.07; confidence interval (CI) 1.10-3.91, p = 0.024), donor age (HR 1.33;CI 1.08-1.63, p = 0.007) and aspartate aminotransferase (HR 1.03;CI 1.01-1.05, p < 0.001) were significantly associated with a higher probability of developing advanced fibrosis, i.e. Knodell fibrosis stage 3 or 4, whereas steatosis (HR 0.94;CI 0.46-1.92, p = 0.87) and acute cellular rejection (HR 1.72;CI 0.88-3.36, p = 0.111) were not. In conclusion, posttransplant insulin resistance is strongly associated with more severe recurrence of HCV infection. HOMA-IR is an important tool for the identification of insulin resistance among patients at risk for rapid fibrosis progression after liver transplantation for HCV.

Recent studies suggest that diabetes mellitus increases the risk of developing hepatocellular carcinoma (HCC). The aim of this study is to quantify the risk of HCC among patients with both diabetes mellitus and hepatitis C in a large cohort of patients with chronic hepatitis C and advanced fibrosis. We included 541 patients of whom 85 (16%) had diabetes mellitus. The median age at inclusion was 50 years. The prevalence of diabetes mellitus was 10.5% for patients with Ishak fibrosis score 4, 12.5% for Ishak score 5, and 19.1% for Ishak score 6. Multiple logistic regression analysis showed an increased risk of diabetes mellitus for patients with an elevated body mass index (BMI) (odds ratio [OR], 1.05; 95% confidence interval [CI], 1.00-1.11; P = 0.060) and a decreased risk of diabetes mellitus for patients with higher serum albumin levels (OR, 0.81; 95% CI, 0.63-1.04; P = 0.095). During a median follow-up of 4.0 years (interquartile range, 2.0-6.7), 11 patients (13%) with diabetes mellitus versus 27 patients (5.9%) without diabetes mellitus developed HCC, the 5-year occurrence of HCC being 11.4% (95% CI, 3.0-19.8) and 5.0% (95% CI, 2.2-7.8), respectively (P = 0.013). Multivariate Cox regression analysis of patients with Ishak 6 cirrhosis showed that diabetes mellitus was independently associated with the development of HCC (hazard ratio, 3.28; 95% CI, 1.35-7.97; P = 0.009). Conclusion: For patients with chronic hepatitis C and advanced cirrhosis, diabetes mellitus increases the risk of developing HCC. (HEPATOLOGY 2008;47:1856–1862.)

Summary Background : Current guidelines for stopping treatment of chronic hepatitis C are based on hepatitis C ribonucleic acid measurements at 12 and 24 weeks. Aim : To explore an alternative approach for making individualized recommendations about treatment duration, based on simple alanine aminotransferase tests and on cost-per-cure. Methods : We analysed individual patient data from 13 randomized, controlled trials with interferon alone or combined with ribavirin. Using multiple logistic regression, we built a model that estimated the probability of sustained virological response for treatment durations of 24 and 48 weeks. Decisions to prolong treatment were based on an increase in probability of sustained virological response. If the increase was 10%, the cost-per-cure became decisive with a limit of 50 000 €. Results : Noncirrhotics with genotype 2 or 3 did not benefit when treatment was continued beyond 24 weeks. Sustained virological response rates in cirrhotic patients increased by 14–47% if treatment was continued up to 48 weeks. In noncirrhotic genotype 1 or 4 patients who had elevated alanine aminotransferase levels at week 4, the probability of sustained virological response increased by

Pegylated interferon is still the backbone of hepatitis C treatment and may cause thrombocytopenia, leading to dose reductions, early discontinuation, and eventually worse clinical outcome. We assessed associations between interferon-induced thrombocytopenia and bleeding complications, interferon dose reductions, early treatment discontinuation, as well as SVR and long-term clinical outcome.All consecutive patients with chronic HCV infection and biopsy-proven advanced hepatic fibrosis (Ishak 4-6) who initiated interferon-based therapy between 1990 and 2003 in 5 large hepatology units in Europe and Canada were included.Overall, 859 treatments were administered to 546 patients. Baseline platelets (in 10(9)/L) were normal (⩾150) in 394 (46%) treatments; thrombocytopenia was moderate (75-149) in 324 (38%) and severe (75) in 53 (6%) treatments. Thrombocytopenia-induced interferon dose reductions occurred in 3 (1%); 46 (16%), and 15 (30%) treatments respectively (p0.001); interferon was discontinued due to thrombocytopenia in 1 (1%), 8 (3%), and in 8 (16%) treatments respectively (p0.001). In total, 104 bleeding events were reported during 53 treatments. Only two severe bleeding complications occurred. Multivariate analysis showed that cirrhosis and a platelet count below 50 were associated with on-treatment bleeding. Within thrombocytopenic patients, patients attaining SVR had a lower occurrence of liver failure (p0.001), hepatocellular carcinoma (p0.001), liver related death or liver transplantation (p0.001), and all-cause mortality (p=0.001) compared to patients without SVR.Even in thrombocytopenic patients with chronic HCV infection and advanced hepatic fibrosis, on-treatment bleedings are generally mild. SVR was associated with a marked reduction in cirrhosis-related morbidity and mortality, especially in patients with baseline thrombocytopenia.

IL28B polymorphisms are strongly associated with response to treatment for HCV infection. IL28B acts on interferon-stimulated genes via the JAK-STAT pathway, which has been implicated in development of insulin resistance. We investigated whether IL28B polymorphisms are associated with posttransplant diabetes mellitus (DM). Consecutive HCV patients who underwent liver transplantation between 1-1995 and 1-2011 were studied. Genotyping of the polymorphism rs12979860 was performed on DNA collected from donors and recipients. Posttransplant DM was screened for by fasting blood glucoses every 1-3 months. Of 221 included patients, 69 developed posttransplant DM (31%). Twenty-two patients with recipient IL28B genotype TT (48%), 25 with IL28B genotype CT (25%) and 22 with IL28B genotype CC (29%) developed posttransplant DM. TT genotype was statistically significantly associated with posttransplant DM over time (log rank p = 0.012 for TT vs. CT and p = 0.045 for TT vs. CC). Multivariate Cox regression analysis correcting for donor age, body mass index, baseline serum glucose, baseline serum cholesterol, recipient age and treated rejection, showed that recipient IL28B genotype TT was independently associated with posttransplant DM (hazard ratio 2.51; 95% confidence interval 1.17-5.40; p = 0.011). We conclude that the risk of developing posttransplant DM is significantly increased in recipients carrying the TT polymorphism of the IL28B gene.

Hepatitis C-associated liver disease is the most common indication for liver transplantation. Virological recurrence is ubiquitous. While the histological impact of recurrence varies substantially between recipients, approximately 30% of HCV-infected recipients will die or lose their allograft or develop cirrhosis secondary to hepatitis C recurrence by the fifth postoperative year. Viral, recipient, and donor factors affect the likelihood if more severe recurrence. Recipient and donor age, utilization of posttransplant antiviral therapy, higher pre- and posttransplant levels of HCV viremia, corticosteroid boluses for acute cellular rejection, Cytomegalovirus (CMV) disease, metabolic syndrome, HIV coinfection, and non-CC IL28B genotype all are associated with more severe recurrence. Strategies for minimizing the frequency of severe HCV recurrence are evolving and include avoidance of older donors, early diagnosis/treatment of CMV, and minimization of immunosuppression and avoidance of pulsed corticosteroid treatment of acute cellular rejection. Patients should be offered treatment with peginterferon and ribavirin as soon as histological evidence of recurrence of HCV is apparent.

Polymorphism in the interleukin-28B (IL28B) gene region, encoding interferon (IFN)-λ3, is strongly predictive of response to antiviral treatment in the nontransplant setting. We sought to determine the prevalence and impact on clinical outcomes of donor and recipient IL28B genotypes among liver transplant recipients. The cohort study included 189 consecutive patients infected with hepatitis C virus (HCV) who underwent liver transplantation between January 1, 1995, and January 1, 2005, at the Mayo Clinic, Rochester, MN. Genotyping of the polymorphism rs12979860 was performed on DNA collected from all donors and recipients in the cohort. Sixty-five patients received IFN-based antiviral therapy. The CC IL28B variant was less common in the chronic HCV-infected recipients than in non-HCV donor livers (33% versus 47%, P = 0.03). IL28B recipient genotype was significantly predictive of fibrosis stage, with TT genotype being associated with more rapid fibrosis (Pearson chi-square P = 0.024 for the comparison G versus A). Donor and recipient IL28B genotype were independently associated with sustained virologic response (P < 0.005). The presence of IL28B CC variant in either the recipient (R) or donor (D) liver was associated with increased rate of sustained virologic response (D-non-CC/R-non-CC = 3/19 [16%] versus D-CC/R-non-CC = 11/22 [50%] versus D-non-CC/R-CC = 5/12 [42%] versus R-CC/D-CC = 6/7 [86%], P = 0.0095). IL28B genotype was not significantly associated with survival (overall/liver-related). Conclusion: Recipient IL28B TT genotype is associated with more severe histological recurrence of HCV. Recipient and donor liver IL28B genotype are strongly and independently associated with IFN-based treatment response in patients after orthotopic liver transplantation. The data suggest that CC donor livers might be preferentially allocated to patients with HCV infection. (Hepatology 2011;)

Hepatitis C-associated liver failure is the most common indication for liver transplantation, with virological recurrence near ubiquitous. Approximately 30% of HCV-infected recipients will die or lose their allograft or develop cirrhosis secondary to hepatitis C recurrence by the fifth postoperative year, with the proportion increasing with duration of follow-up. Strategies for minimizing the frequency of severe HCV recurrence include avoidance of older donors, early diagnosis/treatment of CMV and minimization of immunosuppression, particularly T-cell depleting therapies and pulsed corticosteroid treatment of acute cellular rejection. Patients should be offered treatment with peginterferon and ribavirin before LT if MELD

Recurrent hepatitis C virus (HCV) infection is a major cause of morbidity and mortality after liver transplantation for HCV-related end stage liver disease. Although previous studies have shown a short-term effect of interferon-based treatment on fibrosis progression, it is unclear whether this translates to improved graft survival. We evaluated whether treatment of recurrent HCV leads to an improved graft survival. Cohort study included consecutive HCV patients who underwent liver transplantation between 1 January 1995 and 1 January 2005 in the Mayo Clinic, Rochester, MN. Two hundred and fifteen patients were included in the study. During a median follow-up of 4.4 years (interquartile range 2.2-6.6), 165 patients (77%) had biopsy-proven recurrent HCV infection confirmed by serum HCV RNA testing. Seventy-eight patients were treated. There were no differences in MELD-score, fibrosis stage or time towards HCV recurrence between treated and untreated patients at time of recurrence. There was a trend for greater frequency of acute cellular rejection among untreated patients. The incidence of graft failure was lower for patients treated within 6 months of recurrence compared to patients not treated within this time-period (log rank p = 0.002). Time-dependent multivariate Cox regression analysis showed that treatment of recurrent HCV infection was statistically significantly associated with a decreased risk of overall graft failure (hazard ratio 0.34; CI 0.15-0.77, p = 0.009) and a decreased risk of graft failure due to recurrent HCV (hazard ratio 0.24; CI 0.08-0.69, p = 0.008). In conclusion, although a cause and effect relationship cannot be established, treatment of recurrent HCV infection after liver transplantation is associated with a reduced risk of graft failure.

BACKGROUND: Clinical outcomes of chronic hepatitis C infection in patients with advanced fibrosis include liver failure, hepatocellular carcinoma, and death. OBJECTIVE: To investigate whether sustained virologic response to treatment for hepatitis C is associated with improved clinical outcomes. DESIGN: Retrospective cohort study. SETTING: 5 hepatology units of tertiary care centers in Europe and Canada caring for patients with chronic hepatitis C treated between 1990 and 2003. PATIENTS: Consecutively treated patients with chronic hepatitis C who had biopsy-proven advanced fibrosis or cirrhosis (Ishak score, 4 to 6). MEASUREMENTS: Sustained virologic response, defined as absence of detectable hepatitis C virus RNA at 24 weeks after the end of treatment, and clinical outcomes, defined as death (liver-related or non-liver-related), liver failure, and hepatocellular carcinoma. RESULTS: Of 479 patients, 29.6% had sustained virologic response and 70.3% did not. Median follow-up was 2.1 years (interquartile range, 0.8 to 4.9 years). Four patients with and 83 without sustained virologic response had at least 1 outcome event. Sustained virologic response was associated with a statistically significant reduction in the hazard of events (adjusted hazard ratio, 0.21 [95% CI, 0.07 to 0.58]; P = 0.003). The effect was largely attributable to a reduction in liver failure, which developed in no patients with and 42 patients without sustained virologic response (5-year occurrence, 0% vs. 13.3% [CI, 8.4% to 18.2%]; unadjusted hazard ratio, 0.03 [CI, 0.00 to 0.91]). LIMITATIONS: Because few events occurred in the sustained virologic response group, the study had limited ability to detect differences between groups in individual outcomes. In addition, the study was retrospective; selection and survival biases may therefore influence estimates of effect. CONCLUSION: Sustained virologic response to treatment is associated with improved clinical outcomes, mainly prevention of liver failure, in patients with chronic hepatitis C and advanced fibrosis.

Background: The key end point for treatment efficacy in chronic hepatitis C is absence of detectable virus at six months after treatment. However, the incidence of clinical events during long term follow up of patients with sustained virological response is still poorly documented and may differ between the Eastern and Western world. Aims: To assess clinical end points during long term follow up of European patients with a sustained virological response to interferon monotherapy. Methods: Meta-analysis of individual patient data from eight European protocolled follow up studies of interferon treatment for chronic hepatitis C. Results: A total of 286 sustained virological responders and 50 biochemical responders (detectable virus but normal alanine aminotransferase levels) were followed up for 59 months. Fifteen sustained virological responders (5.2%) had cirrhosis before treatment and 112 (39%) had genotype 1. The late virological relapse rate after five years of follow up was 4.7% (95% confidence interval (CI) 2.0-7.4) among sustained virological responders; all late relapses occurred within four years after treatment. Among sustained virological responders, the rate of decompensation after five years of follow up was 1.0% (95% CI 0.0-2.3) and none developed hepatocellular carcinoma (HCC). Survival was comparable with the general population, matched for age and sex, the standard mortality ratio being 1.4 (95% CI 0.3-2.5). Clinical outcome of patients with cirrhosis was similar to other sustained virological responders. For biochemical responders, the rates of development of decompensation and HCC during long term follow up were 9.1% (95% CI 0.5-17.7) and 7.1% (95% CI 0-15.0), respectively. Conclusions: Five year survival of European sustained virological responders was similar to the overall population, matched for age and sex. No HCCs were detected during long term follow up.

BACKGROUND The current NIH and French consensus provide physicians with clear guidelines on how to care best for patients with hepatitis C. METHODS Review and discussion. RESULTS Confirming the diagnosis and guiding the initial investigations have become straightforward. The standard treatment and its monitoring have been described in many publications. Recommending therapy to patients with moderate fibrosis has been the custom since the 1999 EASL guidelines. The 2002 guidelines have widened the spectrum of patients with chronic hepatitis C that should be considered for antiviral therapy. Patient categories not previously considered for therapy, such as alcoholics, intravenous drug users, prison inmates and social subgroups of society that lack adequate medical care, can now be offered therapy provided they are well supported in specific programmes. Liver physicians have learned throughout the years to manage side effects successfully and encourage patient adherence. This is reflected in the higher sustained viral response rates with standard interferon and ribavirin reported in the pegylated interferon registration trials compared with the interferon-ribavirin trials. Reducing the dose rather than stopping therapy is the key issue. Antidepressive agents have their place in the management of mood disorders prior to or during therapy. CONCLUSION Every patient with chronic hepatitis C should be considered for antiviral therapy. It is probably best for a patient to be treated by a physician who has experience in managing possible side effects and in coaching a patient through his 6 or 12 months of treatment.

Chronic hepatitis C virus (HCV) infection outcomes include liver failure, hepatocellular carcinoma (HCC), and liver-related death.To assess the association between sustained virological response (SVR) and all-cause mortality in patients with chronic HCV infection and advanced hepatic fibrosis.An international, multicenter, long-term follow-up study from 5 large tertiary care hospitals in Europe and Canada of 530 patients with chronic HCV infection who started an interferon-based treatment regimen between 1990 and 2003, following histological proof of advanced hepatic fibrosis or cirrhosis (Ishak score 4-6). Complete follow-up ranged between January 2010 and October 2011.All-cause mortality. Secondary outcomes were liver failure, HCC, and liver-related mortality or liver transplantation.The 530 study patients were followed up for a median (interquartile range [IQR]) of 8.4 (6.4-11.4) years. The baseline median (IQR) age was 48 (42-56) years and 369 patients (70%) were men. The Ishak fibrosis score was 4 in 143 patients (27%), 5 in 101 patients (19%), and 6 in 286 patients (54%). There were 192 patients (36%) who achieved SVR; 13 patients with SVR and 100 without SVR died (10-year cumulative all-cause mortality rate, 8.9% [95% CI, 3.3%-14.5%] with SVR and 26.0% [95% CI, 20.2%-28.4%] without SVR; P.001). In time-dependent multivariate Cox regression analysis, SVR was associated with reduced risk of all-cause mortality (hazard ratio [HR], 0.26; 95% CI, 0.14-0.49; P.001) and reduced risk of liver-related mortality or transplantation (HR, 0.06; 95% CI, 0.02-0.19; P.001), the latter occurring in 3 patients with SVR and 103 without SVR. The 10-year cumulative incidence rate of liver-related mortality or transplantation was 1.9% (95% CI, 0.0%-4.1%) with SVR and 27.4% (95% CI, 22.0%-32.8%) without SVR (P.001). There were 7 patients with SVR and 76 without SVR who developed HCC (10-year cumulative incidence rate, 5.1%; 95% CI, 1.3%-8.9%; vs 21.8%; 95% CI, 16.6%-27.0%; P.001), and 4 patients with SVR and 111 without SVR experienced liver failure (10-year cumulative incidence rate, 2.1%; 95% CI, 0.0%-4.5%; vs 29.9%; 95% CI, 24.3%-35.5%; P.001).Among patients with chronic HCV infection and advanced hepatic fibrosis, sustained virological response to interferon-based treatment was associated with lower all-cause mortality.
