Long-term outcome and eligibility of radiofrequency ablation for hepatocellular carcinoma over 3.0 cm in diameter. Sci Rep 2023; 13:16286. [PMID: 37770523 PMCID: PMC10539460 DOI: 10.1038/s41598-023-43516-w] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2023] [Accepted: 09/25/2023] [Indexed: 09/30/2023] Open
Abstract
Percutaneous radiofrequency ablation (RFA) is effective for the treatment of small hepatocellular carcinoma (HCC) with a diameter ≤ 3.0 cm. The present study aimed to elucidate the prognostic factors and clarify the indication of treatment for RFA outcomes in patients with HCC with a diameter > 3.0 cm. Among 2188 patients with HCC who underwent RFA, 100 patients with HCC with a diameter > 3.0 cm were enrolled in this study between August, 2000 and August, 2021. We analyzed local therapeutic efficacy, long-term outcomes, and prognostic factors in patients with HCC with a diameter > 3.0 cm. Among all patients, 77 patients achieved complete ablation in one session. There were no treatment-related deaths or major complications. Local tumor recurrence occurred in 48% (n = 48) of the patients, and distant tumor recurrence occurred in 82% (n = 82) of the patients during the study period. The survival rates at 1-, 3-, 5-, 10-, and 15- years were 93.0%, 66.0%, 40.0%, 15.5%, and 10.2%, respectively. Cox proportional hazards regression analysis confirmed that distant tumor recurrence, Child-Pugh class B, and pre-ablation des-γ-carboxy prothrombin (DCP) levels ≥ 200 mAU/mL were independent unfavorable prognostic factors with a hazard ratio of 3.34 (95% CI, 1.57-7.11; P = 0.002), 2.43 (95% CI, 1.35-4.37; P = 0.003), and 1.83 (95% CI, 1.14-2.93; P = 0.012), respectively. In conclusion, patients with HCC with a diameter > 3.0 cm with Child-Pugh class A and DCP levels < 200 mAU/mL might be eligible for RFA treatment.

Abstract
Given that evidence supporting chronic hepatitis C (CHC) infection developed chance for hepatocellular carcinoma (HCC) following antiviral agents therapy is controversial. We conducted a meta-analysis to examine the risk.We evaluated 20 retrospective and prospective cohort studies published up to 31 December 2017 which investigated the association between sustained virological response (SVR) and incidence of HCC patients treated with monotherapy interferon (IFN) or IFN plus ribavirin (RBV) therapy. The primary outcome of the study was the cumulative incidence of HCC. Odds ratio (OR) was used to evaluate the index of effect size for the association between SVR and treatment with IFN alone or IFN/RBV in CHC patients.SVR patients demonstrated a lower incidence of HCC compared to non-SVR patients. Non-SVR patients had greater odds of HCC incidence compared to SVR patients in the treatment of IFN plus RBV (pooled OR = 7.405, 95% CI = 4.689 to 11.694, P < .001). Non-SVR patients had greater odds of HCC incidence compared to SVR patients in the treatment of IFN monotherapy (pooled OR = 4.135, 95% CI = 3.009 to 5.682, P < .001). Lack of SVR to IFN therapy was significantly associated with greater risk of HCC incidence (pooled OR = 5.035, 95% CI = 3.915 to 6.474, P < .001).SVR could be as a predictor of HCC in CHC patients treated with IFN or IFN plus RBV, and have important implications during HCC screening, whereby patients who fail to achieve SVR need to be screened more rigorously.

Abstract
Purpose of review Hepatitis C (HCV) is the most common cause of viral hepatitis in elderly individuals. This patient population previously experienced suboptimal outcomes with interferon-based regimens. Unfortunately, patients aged 65 years and older were underrepresented in phase 2 and 3 clinical trials with newer direct acting antiviral (DAA) therapies. Since the advent of second-generation DAA in 2013, numerous robust real-world experiences highlighting the efficacy and safety of DAA in the elderly have been published. This review article summarizes the cascade of care for hepatitis C from diagnosis to cure from an evidence-based perspective of the aging population. Recent finding In a large study from the Veterans Affairs Healthcare System, the overall sustained virologic response (SVR) of 15,884 patients treated with DAA regimens was 91.2%. These newer therapies remained highly effective in the subset of patients aged 65 years and older with SVR rates above 90%. A Spanish National Registry reported outcomes in patients ≥ 65 years old treated for HCV with oral DAA regimens over a 2-year period. The overall SVR was 94% in the study of 1252 subjects. Summary Current real-world data imply DAA treatment regimens remain highly effective and safe in elderly patients when compared to the general population.

Abstract
IMPORTANCE A 2013 review for the US Preventive Services Task Force (USPSTF) of hepatitis C virus (HCV) screening found interferon-based antiviral therapy associated with increased likelihood of sustained virologic response (SVR) and an association between achieving an SVR and improved clinical outcomes. New direct-acting antiviral (DAA) regimens are available. OBJECTIVE To update the 2013 review on HCV screening to inform the USPSTF. DATA SOURCES Ovid MEDLINE, the Cochrane Central Register of Controlled Trials, and the Cochrane Database of Systematic Reviews through February 2019, with surveillance through September 2019. STUDY SELECTION Randomized clinical trials (RCTs) and nonrandomized treatment studies of HCV screening and DAA therapy; cohort studies on screening, antiviral therapy, and the association between an SVR after antiviral therapy and clinical outcomes. DATA EXTRACTION AND SYNTHESIS One investigator abstracted data; a second checked accuracy. Two investigators independently rated study quality. MAIN OUTCOMES AND MEASURES Mortality, morbidity, quality of life, screening and treatment harms, and screening diagnostic yield. RESULTS Eight RCTs of DAA therapy vs placebo or an outdated antiviral regimen, 48 other treatment studies, and 33 cohort studies, with a total of 179 230 participants, were included. No study evaluated effects of HCV screening vs no screening. One new study since the 2013 review (n = 5917) found similar diagnostic yield of risk-based screening (sensitivity, 82%; number needed to screen to identify 1 HCV case, 15) and birth cohort screening (sensitivity, 76%; number needed to screen, 29), assuming perfect implementation. Ten open-label studies (n = 3292) reported small improvements in some quality-of-life and functional outcomes (eg, less than 3 points on the 0 to 100 36-Item Short Form Health Survey physical and mental component summary scales) after DAA treatment compared with before treatment. Two cohort studies (n = 24 686) found inconsistent associations of antiviral therapy vs no therapy with risk of hepatocellular carcinoma. Forty-nine treatment studies (n = 10 181) found DAA regimens associated with pooled SVR rates greater than 95% across genotypes, and low short-term rates of serious adverse events (1.9%) and withdrawal due to adverse events (0.4%). An SVR after antiviral therapy was associated with decreased adjusted risk of all-cause mortality (13 studies, n = 36 986; pooled hazard ratio [HR], 0.40 [95% CI, 0.28-0.56) and hepatocellular carcinoma (20 studies, n = 84 491; pooled HR, 0.29 [95% CI, 0.23 to 0.38]) vs no SVR. CONCLUSIONS AND RELEVANCE Direct evidence on the effects of HCV screening on clinical outcomes remains unavailable, but DAA regimens were associated with SVR rates greater than 5% and few short-term harms relative to older antiviral therapies. An SVR after antiviral therapy was associated with improved clinical outcomes compared with no SVR.

Abstract
BACKGROUND Sustained virological response (SVR) rates for the treatment of chronic hepatitis C virus (HCV)-infected patients have drastically improved with the use of direct-acting antiviral (DAA) therapies; however, a small minority of patients still fails to eradicate the virus. We analyzed factors associated with SVR in DAA therapy and the effect of age and liver fibrosis on treatment response. METHODS Nine hundred and eighteen patients with chronic HCV infection were treated with 24 weeks of daclatasvir plus asunaprevir (DCV + ASV) or 12 weeks of sofosbuvir plus ledipasvir (SOF + LDV), ombitasvir, paritaprevir plus ritonavir (OMB + PTV + r) or sofosbuvir plus ribavirin (SOF + RBV). Multivariate logistic regression analysis was used to identify factors associated with SVR. The effect of age and liver fibrosis on SVR was analyzed. RESULTS The overall SVR rate was 95.4% (876 of 918 patients), and rates by DAA regimen were 93.4%, 95.7%, 100%, and 95.0% in DCV + ASV-treated, SOF + LDV-treated, OMB + PTV + r-treated, and SOF + RBV-treated patients, respectively. Patients older than 75 years achieved a similar SVR rate with those aged 75 years or younger (96.4% and 94.8%, respectively). Multivariate logistic regression analysis identified absence of DAA therapy history (odds ratio [OR], 3.868 for presence; P = 0.002) and FIB-4 index of less than 3.25 (OR, 5.042 for ≥3.25; P = 0.001) as independent predictors for SVR. SVR rates were significantly lower in patients with FIB4 index of 3.25 or more compared with those with less than 3.25, especially in sofosbuvir-based therapies such as SOF + LDV-treated or SOF + RBV-treated patients. CONCLUSION Both older and younger patients respond similarly to DAA therapy. Advanced liver fibrosis affects the virological response to sofosbuvir-based therapy.

Abstract
Background The long-term clinical outcomes of antiviral therapy for patients with chronic hepatitis C are uncertain in terms of hepatitis C virus (HCV)-related morbidity and mortality according to the response to antiviral therapy. This study aimed to assess the impact of antiviral treatment on the development of HCC and mortality in patients with chronic HCV infection. Methods A systematic review was conducted for studies that evaluated the antiviral efficacy for patients with chronic hepatitis C or assessed the development of HCC or mortality between SVR (sustained virologic response) and non-SVR patients. The methodological quality of the enrolled publications was evaluated using Risk of Bias table or Newcastle-Ottawa scale. Random-effect model meta-analyses and meta-regression were performed. Publication bias was assessed. Results In total, 59 studies (4 RCTs, 15 prospective and 40 retrospective cohort studies) were included. Antiviral treatment was associated with reduced development of HCC (vs. no treatment; OR 0.392, 95% CI 0.275–0.557), and this effect was intensified when SVR was achieved (vs. no SVR, OR: 0.203, 95% CI 0.164–0.251). Antiviral treatment was associated with lower all-cause mortality (vs. no treatment; OR 0.380, 95% CI 0.295–0.489) and liver-specific mortality (OR 0.363, 95% CI 0.260–0.508). This rate was also intensified when SVR was achieved [all-cause mortality (vs. no SVR, OR 0.255, 95% CI 0.199–0.326), liver-specific mortality (OR 0.126, 95% CI 0.094–0.169)]. Sensitivity analyses revealed robust results, and a small study effect was minimal. Conclusions In patients with chronic hepatitis C, antiviral therapy can reduce the development of HCC and mortality, especially when SVR is achieved.

Abstract
BACKGROUND Daclatasvir and asunaprevir combination therapy has shown a high virological response for chronic genotype 1 hepatitis C virus (HCV)-infected patients. However, the safety and efficacy of the therapy for older patients are unknown. METHODS One hundred seventy patients younger than 75 years and 139 patients aged 75 years or older with genotype 1 HCV infection were treated for 24 weeks with daclatasvir plus asunaprevir. Pretreatment drug-resistance-associated variants at NS5A-L31 and NS5A-Y93 were determined by the Invader assay. Virological response and adverse events according to age were analyzed. RESULTS The sustained virological response (SVR) rate for older patients was similar to that for younger patients (97.1 and 92.4 % respectively). In multivariate regression analysis, prior simeprevir treatment (odds ratio 56.6 for absence; P < 0.001) was identified as a significant independent predictor of SVR. The SVR rate for patients with pretreatment resistance-associated variants (RAVs) at a low population frequency (less than 25 %) was similar to that for patients with no detectable RAVs. The frequency of adverse events was similar between younger and older patients. All 19 very elderly patients (85 years or older) completed the 24 weeks of treatment and achieved SVR. CONCLUSIONS Older patients have a virological response and tolerance of daclatasvir plus asunaprevir therapy similar to those of younger patients. Even though RAVs were detected, virological response similar to that for patients with no detectable RAVs may still be expected for patients with RAVs as long as the population frequency is low.

Improved Survival Among all Interferon-α-Treated Patients in HCV-002, a Veterans Affairs Hepatitis C Cohort of 2211 Patients, Despite Increased Cirrhosis Among Nonresponders. Dig Dis Sci 2016; 61:1744-56. [PMID: 27059981 PMCID: PMC5308124 DOI: 10.1007/s10620-016-4122-5] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/23/2015] [Accepted: 03/06/2016] [Indexed: 02/06/2023]
Abstract
BACKGROUND As the era of interferon-alpha (IFN)-based therapy for hepatitis C ends, long-term treatment outcomes are now being evaluated. AIM To more fully understand the natural history of hepatitis C infection by following a multisite cohort of patients. METHODS Patients with chronic HCV were prospectively enrolled in 1999-2000 from 11 VA medical centers and followed through retrospective medical record review. RESULTS A total of 2211 patients were followed for an average of 8.5 years after enrollment. Thirty-one percent of patients received HCV antiviral therapy, 15 % with standard IFN/ribavirin only, 16 % with pegylated IFN/ribavirin, and 26.7 % of treated patients achieved sustained virologic response (SVR). Cirrhosis developed in 25.8 % of patients. Treatment nonresponders had a greater than twofold increase in the hazard of cirrhosis and hepatocellular carcinoma, compared to untreated patients, whereas SVR patients were only marginally protected from cirrhosis. Nearly 6 % developed hepatocellular carcinoma, and 27.1 % died during the follow-up period. Treated patients, regardless of response, had a significant survival benefit compared to untreated patients (HR 0.58, CI 0.46-0.72). Improved survival was also associated with college education, younger age, lower levels of alcohol consumption, and longer duration of medical service follow-up-factors typically associated with treatment eligibility. CONCLUSIONS As more hepatitis C patients are now being assessed for all-oral combination therapy, these results highlight that patient compliance and limiting harmful behaviors contribute a significant proportion of the survival benefit in treated patients and that the long-term clinical benefits of SVR may be less profound than previously reported.

Abstract
The liver is the major organ for the metabolism of three major nutrients: protein, fat, and carbohydrate. Chronic hepatitis C virus infection is the major cause of chronic liver disease. Liver cirrhosis (LC) results from different mechanisms of liver injury that lead to necroinflammation and fibrosis. LC has been seen to be not a single disease entity but one that can be graded into distinct clinical stages related to clinical outcome. Several noninvasive methods have been developed for assessing liver fibrosis and these methods have been used for predicting prognosis in patients with LC. On the other hand, subjects with LC often have protein-energy malnutrition (PEM) and poor physical activity. These conditions often result in sarcopenia, which is the loss of skeletal muscle volume and increased muscle weakness. Recent studies have demonstrated that PEM and sarcopenia are predictive factors for poorer survival in patients with LC. Based on these backgrounds, several methods for evaluating nutritional status in patients with chronic liver disease have been developed and they have been preferably used in the clinical field practice. In this review, we will summarize the current knowledge in the field of LC from the viewpoints of diagnostic method, nutritional status, and clinical outcomes.

Abstract
Due to the progressive aging of the hepatitis C virus (HCV) population which have acquired the infection during its maximum spread after the Second World War, the management of the elderly HCV-infected patient is emerging as a hot topic. Unfortunately, although it is recognized that the progression of HCV-related liver disease gets faster with aging, and that even extra-hepatic manifestations of HCV infection are probably worse in the elderly, till now, treatment attempts in this population have been significantly limited by the well-known contraindications and side effects of interferon (IFN). The arrival of several new anti-HCV drugs, and the possibility to combine them in safe and effective anti-viral regimens, is relighting the hope of a cure for many elderly patients who had been cut out of IFN-based treatments. However, although these new regimens will be certainly more manageable, it should be underscored that IFN-free doesn’t mean free from any contraindication or side-effect. Moreover, one issue which promises to become central is that of the possible interactions between antiviral therapy and the multiple drugs frequently assumed by elderly patients because of comorbidities. In this review, we will revise the epidemiology pointing to HCV as an infection of the elderly, the evidences that HCV harms the health of the aged patient more than that of the young one, and the available experiences of HCV treatment in the elderly with the “old” IFN-based regimens and with the newer drugs. We will conclude that the availability of IFN-free regimens should prompt us to change our mind and consider a significantly larger number of possible candidates among elderly patients, who would take significant advantage from viral eradication. Rather than the anagraphic age, drug-drug interactions and, mainly in case of economic restrictions, an evaluation of life expectancy dependent on liver disease with respect to that dependent on comorbidities, are likely to be the key issues guiding treatment indication in the next future. The sooner we will change our mind with respect to an a priori obstacle for anti-HCV treatment in the elderly, the sooner we will begin to spare many aged HCV patients from avoidable liver-related complications.

Long-Term Treatment Outcomes of Patients Infected With Hepatitis C Virus: A Systematic Review and Meta-analysis of the Survival Benefit of Achieving a Sustained Virological Response.

Abstract
The results of this meta-analysis suggest that there is a significant survival benefit of achieving an sustained virologic response compared with unsuccessful treatment in the general hepatitis C virus-infected population. This benefit is held in patients with cirrhosis and those coinfected with human immunodeficiency virus. Background. Achievement of a sustained virologic response (SVR) after treatment for Hepatitis C infection is associated with improved outcomes. This meta-analysis aimed to determine the impact of SVR on long-term mortality risk compared with nonresponders in a range of populations. Methods. An electronic search identified all studies assessing all-cause mortality in SVR and non-SVR patients. Eligible articles were stratified into general, cirrhotic, and populations coinfected with human immunodeficiency virus. The adjusted hazard ratio (95% confidence interval [CI]) for mortality in patients achieving SVR vs non-SVR, and pooled estimates for the 5-year mortality in each group were calculated. Results. 31 studies (n = 33 360) were identified as suitable for inclusion. Median follow-up time was 5.4 years (interquartile range, 4.9–7.5) across all studies. The adjusted hazard ratio of mortality for patients achieving SVR vs non-SVR was 0.50 (95% CI, .37–.67) in the general population, 0.26 (95% CI, .18–.74) in the cirrhotic group, and 0.21 (.10–.45) in the coinfected group. The pooled 5-year mortality rates were significantly lower for patients achieving SVR compared with non-SVR in all 3 populations. Conclusions. The results suggest that there is a significant survival benefit of achieving an SVR compared with unsuccessful treatment in a range of populations infected with hepatitis C virus.

Abstract
BACKGROUND AND AIMS The population of patients chronically infected with hepatitis C virus (HCV) is aging, and the number of older patients with HCV-related hepatocellular carcinoma (HCC) is increasing. The purpose of this study was to elucidate the effects of peginterferon and ribavirin combination therapy on prevention of HCC in older patients with chronic hepatitis C (CH-C). METHODS We compared the sustained virological response (SVR) and treatment discontinuation rates between older (≥ 65 years) and younger patients (< 65 years) among 1280 CH-C patients treated with peginterferon alfa-2b and ribavirin. Cumulative incidence of HCC was determined by Kaplan-Meier analysis, and factors associated with liver carcinogenesis were analyzed by Cox proportional hazards regression. RESULTS Older patients had a significantly lower SVR rate and a significantly higher discontinuation rate of treatment than younger patients. Fifty patients developed HCC during median follow-up period of 47 months. Cox proportional hazards regression analysis indicated that the following were independent risk factors associated with the development of HCC: older age, male, advanced fibrosis, non-SVR in all patients: higher gamma-glutamyltranspeptidase, and non-SVR in older patients. Older patients who achieved SVR had a significantly reduced rate of HCC compared with those who did not achieve SVR, especially those who had gamma-glutamyltranspeptidase over 44 IU/L. CONCLUSIONS The SVR rate was lower and the combination therapy discontinuation rate was higher in older CH-C patients than in younger patients. However, older patients who achieved SVR had a markedly lower rate of HCC development compared with older patients who did not achieve SVR.

Abstract
Hepatitis C is a common infection worldwide. It is a major cause of cirrhosis and its complications, including hepatocellular carcinoma and liver transplantation. Treatment of hepatitis C has dramatically improved since its discovery. Current treatment includes pegylated interferon and ribavirin, and the addition of the protease inhibitors telaprevir, boceprevir, or simeprevir, or the polymerase inhibitor sofosbuvir. The rate of sustained viral response, considered a cure, now approaches 80 %. These treatments are complex, with multiple morbidities and drug interactions. The majority of patients with chronic hepatitis C are from the birth cohort of the 'baby boomer' years (1945-1965) with the oldest already 68 years old. In spite of this, most hepatitis C patients in clinical trials have been much younger and this is still the case in the ongoing studies. Thus, the group of patients most likely to require treatment in the future will have decisions made with a relative lack of evidence-based medicine. It is the purpose of this article to review the epidemiology, clinical manifestations, and treatment of hepatitis C with the data available in the aged population.

Abstract
BACKGROUND Older patients with chronic hepatitis C have a lower virological response to interferon (IFN) treatment compared to younger patients. The efficacy of telaprevir (TVR) and PEG-IFN plus ribavirin combination therapy and the predictive value of recently identified IFN lambda (IFNL) 4 polymorphisms on the outcome of therapy for older patients have not been addressed. METHODS We assessed predictive factors for sustained virological response (SVR) to triple therapy in 226 younger (≤65 years) and 87 older (>65 years) Japanese patients with chronic genotype 1 hepatitis C. IFNL4 polymorphism ss469415590 was analyzed by Invader assay. RESULTS The SVR rate for older patients was slightly lower than for younger patients (69 vs. 82%, P = 0.043). In the older group, the SVR rate for patients with the IFNL4 TT/TT genotype was significantly higher than patients with TT/ΔG or ΔG/ΔG genotypes (81.8 and 42.9%, P = 0.003). In multivariate regression analysis, rapid virological response (OR 36.601, P = 0.002) and IFNL4 TT/TT genotype (OR 19.502, P = 0.009) were identified as significant independent predictors for SVR in older patients. Treatment-related decreases in hemoglobin and increases in serum creatinine were higher in older patients than younger patients. Reduction of initial TVR dose to 1,500 mg per day alleviated these adverse events without compromising SVR rate in older patients. CONCLUSIONS Analysis of IFNL4 polymorphisms is a valuable predictor in older patients receiving TVR triple therapy. 1,500 mg per day is a suitable initial TVR dose for older Japanese patients.

Abstract
AIM We aimed to determine whether pretreatment serum interferon-γ-inducible protein (IP)-10 concentration can predict response to telaprevir (TVR)-based triple therapy in patients with genotype 1 chronic hepatitis C (CHC), and to examine the effects of IP-10 concentration on liver histology. METHODS Baseline IP-10 concentrations were measured in 97 patients with genotype 1 CHC treated with TVR-based triple therapy, and the associations between baseline IP-10 and treatment outcome were assessed by univariate and multivariate analyses. Associations between baseline serum IP-10 concentration and laboratory data and liver histological findings were also investigated. RESULTS Median IP-10 concentration in these patients was 461.83 pg/mL (range, 151.35-4297.62). Multivariate analysis showed that IL28B genotype (P = 0.025) and IP-10 level (P = 0.004) were factors significantly predictive of rapid virological response (RVR), whereas in pretreatment factors only, IL28B genotype (P = 0.001) and liver fibrosis (P = 0.035) were independent predictors of sustained virological response. Using a cut-off IP-10 concentration of 460 pg/mL, patients with IL28B risk allele and low IP-10 had a significantly higher RVR rate than those with high IP-10 (P = 0.005). IP-10 concentration was significantly correlated with liver fibrosis (P = 0.001) and inflammation activity (P = 0.006) and had the highest areas under the curve for liver histological findings. CONCLUSION Baseline serum IP-10 level is a useful predictor of virological response in patients with genotype 1 CHC treated with TVR-based triple therapy, especially in patients with IL28B risk allele. IP-10 was well correlated with liver fibrosis and inflammation.

Abstract
INTRODUCTION The population of patients with hepatitis C is aging. In some countries, the prevalence of hepatitis C virus (HCV) is actually greater in older patients than in younger individuals. It is also anticipated that hepatitis C will increasingly become a disease of older persons. However, patients older than 70 years are typically excluded from clinical trials. The decision to treat older patients is complex and cannot be made at the sole discretion of the physician. AREAS COVERED There is an urgent need to analyze treatment outcomes in the elderly to examine response rates in order to aid in therapeutic decision making. EXPERT OPINION In geriatric HCV-infected patients, dual therapy with pegylated IFN plus ribavirin is associated with a lower sustained virologic response and a higher discontinuation rate. Even the first-generation protease inhibitors are associated with high rates of side effects, in particular in elderly patients with a high prevalence of comorbidities. The recent development of interferon-sparing regimens could change the treatment paradigm in this setting, and a much larger number of patients could have access to the antiviral therapy programs.

Abstract
AIM: To evaluate the safety and efficacy of pegylated interferon alfa-2a and ribavirin therapy in elderly patients with chronic hepatitis C infection.
METHODS: Patients characteristics, treatment results and safety profiles of 4859 patients with hepatitis c virus (HCV) infection receiving treatment with pegylated interferon alfa-2a and ribavirin were retrieved from a large ongoing German multicentre non-interventional study. Recommended treatment duration was 24 wk for GT 2 and GT 3 infection and 48 wk for GT 1 and GT 4 infection. Patients were stratified according to age (< 60 years vs≥ 60 years). Because of limited numbers of liver biopsies for further assessment of liver fibrosis APRI (aspartate aminotransferase - platelet ratio index) was performed using pre-treatment laboratory data.
RESULTS: Out of 4859 treated HCV patients 301 (6.2%) were ≥ 60 years. There were more women (55.8% vs 34.2%, P < 0.001) and predominantly GT 1 (81.4% vs 57.3%, P < 0.001) infected patients in the group of patients aged ≥ 60 years and they presented more frequently with metabolic (17.6% vs 4.5%, P < 0.001) and cardiovascular comorbidities (32.6% vs 6.7%, P < 0.001) and significant fibrosis and cirrhosis (F3/4 31.1% vs 14.0%, P = 0.0003). Frequency of dose reduction and treatment discontinuation were significantly higher in elderly patients (30.9% vs 13.7%, P < 0.001 and 47.8% vs 30.8%, P < 0.001). Main reason for treatment discontinuation was “virological non-response” (26.6% vs 13.6%). Sustained virological response (SVR) rates showed an age related difference in patients with genotype 1 (23.7% vs 43.7%, P < 0.001) but not in genotype 2/3 infections (57.7% vs 64.6%, P = 0.341). By multivariate analysis, age and stage of liver disease were independent factors of SVR.
CONCLUSION: Elderly HCV patients differ in clinical characteristics and treatment outcome from younger patients and demand special attention from their practitioner.

Abstract
BACKGROUND & AIMS Age is frequently discussed as negative host factor to achieve a sustained virological response (SVR) to antiviral therapy of chronic hepatitis C. However, elderly patients often show advanced fibrosis/cirrhosis as known negative predictive factor. The aim of this study was to assess age as an independent predictive factor during antiviral therapy. METHODS Overall, 516 hepatitis C patients were treated with pegylated interferon-α and ribavirin, thereof 66 patients ≥60 years. We analysed the impact of host factors (age, gender, fibrosis, haemoglobin, previous hepatitis C treatment) and viral factors (genotype, viral load) on SVR per therapy course by performing a generalized estimating equations (GEE) regression modelling, a matched pair analysis and a classification tree analysis. RESULTS Overall, SVR per therapy course was 42.9 and 26.1%, respectively, in young and elderly patients with hepatitis C virus (HCV) genotypes 1/4/6. The corresponding figures for HCV genotypes 2/3 were 74.4 and 84%. In the GEE model, age had no significant influence on achieving SVR. In matched pair analysis, SVR was not different in young and elderly patients (54.2 and 55.9% respectively; P = 0.795 in binominal test). In classification tree analysis, age was not a relevant splitting variable. CONCLUSIONS Age is not a significant predictive factor for achieving SVR, when relevant confounders are taken into account. As life expectancy in Western Europe at age 60 is more than 20 years, it is reasonable to treat chronic hepatitis C in selected elderly patients with relevant fibrosis or cirrhosis but without major concomitant diseases, as SVR improves survival and reduces carcinogenesis.

Low-dose pegylated interferon-alpha-2a monotherapy in elderly and/or cirrhotic patients infected with hepatitis C virus genotype-2 or genotype-1 low level infection. Hepatol Res 2013; 43:702-8. [PMID: 23252609 DOI: 10.1111/hepr.12024] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/21/2012] [Revised: 11/09/2012] [Accepted: 11/11/2012] [Indexed: 01/01/2023]
Abstract
AIM Elderly and/or cirrhotic patients with hepatitis C virus (HCV) are at high risk of adverse effects during interferon therapy. The aim of the present study was to evaluate the efficacy, safety and predictive factors for sustained virological response (SVR) of low-dose pegylated interferon-α-2a (PEG IFN-α-2a) monotherapy in elderly and/or cirrhotic patients with HCV genotype-2 or genotype-1 low level infection. METHODS Sixty-four elderly (≥65 years) and/or cirrhotic patients with HCV genotype-2 or genotype-1 low level (<5 logIU/mL) infection underwent low-dose PEG IFN-α-2a (90 μg/week) monotherapy for 24 weeks. Sixty patients were available for efficacy assessment. RESULTS SVR was achieved in 78.3%. SVR rates according to genotype-1 low, genotype-2 low and genotype-2 high viral load were 90.0%, 87.1% and 57.9%, respectively. The discontinuation rate was 12.5%. PEG IFN-α-2a was interrupted or discontinued in four patients because of severe thrombocytopenia (<25 000/mm(3) ). The baseline platelet counts of all these patients were less than 70 000/mm(3) . On univariate analysis of factors contributing to SVR, significant differences were noted in viral load, platelet count, γ-glutamyltransferase, ferritin, α-fetoprotein level and rapid viral response (RVR). On multivariate analysis, RVR was the only independent factor (P = 0.010, odds ratio = 47.27). The positive and negative SVR-predictive values based on RVR were 95% and 82%, respectively. CONCLUSION Low-dose PEG IFN-α-2a monotherapy was effective and tolerable in elderly and/or cirrhotic patients with genotype-2 or genotype-1 low HCV level infection. However, a baseline platelet count of more than 70 000/mm(3) is needed for safety. RVR can predict SVR accurately.

Abstract
BACKGROUND Limited data are available on the efficacy and safety of antiviral therapy in geriatric patients with chronic hepatitis C virus (HCV) infection. AIM To evaluate the efficacy and safety of pegylated interferon (pegIFN) plus ribavirin (RBV) therapy in geriatric HCV-infected patients. METHODS Ninety-one geriatric patients (age ≥65 years; the elderly group) with HCV infection and 91 gender- and HCV genotype-matched middle-aged patients (age 50-64 years; the younger group) were assigned to receive weekly pegIFN injection plus weight-based oral RBV for 24 weeks. The on- and off-treatment virological responses were evaluated for treatment efficacy. RESULTS In intention-to-treat analysis, the sustained virological response (SVR) rate was substantially decreased in the elderly patients (elderly group vs. younger group, 40.7% vs. 61.5%, respectively; P = 0.005). The SVR rate was significantly lower in geriatric patients than in middle-aged patients with HCV genotype non-1 (54.3% vs. 82.9%; P = 0.01), but the difference was not significant with HCV genotype 1 (32.1% vs. 48.2%; P = 0.083). Furthermore, the older patients infected with HCV genotype non-1 who achieved a rapid virological response had a similar SVR rate to that of the younger patients. The withdrawal rate was 13.2% in the elderly group and 7.7% in the younger group. CONCLUSIONS Compared with middle-aged patients, the therapeutic efficacy of pegylated interferon plus ribavirin therapy is lower in hepatitis C virus-infected geriatric patients with an acceptable withdrawal rate. Considering prolonged lifespan in geriatric patients, we recommend treating geriatric hepatitis C virus-infected patients who have significant hepatic fibrosis and no other health problems.

Abstract
PURPOSE Cancer patients were generally excluded from the therapeutic guidelines of antiviral therapy. We aimed to evaluate the efficacy and safety of antiviral therapy in patients with hepatitis C virus (HCV) infection concomitant with malignancy other than hepatocellular carcinoma (HCC). METHODS Twenty-five HCV patients with curative malignancy other than HCC (group A) and 75 sex- and age-matched controls (group B) were recruited into a prospective and case-control analysis. All patients received peginterferon-alpha-2a (PegIFN-alpha-2a) and weight-based ribavirin according to the current treatment recommendations. The primary outcome measurement was sustained virological response (SVR). The safety issue between groups was also compared. RESULTS There were 22 (88.0 %) patients of group A and 59 (78.7 %) patients of group B who achieved an SVR (p = 0.39). The SVR rate was comparable between groups both in genotype-1 (HCV-1) (81.8 vs. 72.7 %, p = 0.70) and in genotype-2 (HCV-2) (92.9 vs. 83.3 %, p = 0.66) patients. Multivariate logistic regression analysis demonstrated that the achievement of a RVR (viral clearance during first 4 weeks of treatment) was the strongest predictor of an SVR (odds ratio/95 % confidence intervals [OR/CI]: 6.357/1.50 - 26.99, p = 0.01), followed by lower baseline viral loads (OR/CI: 0.403/0.174 - 0.936, p = 0.034) and higher dose of ribavirin exposure (OR/CI: 1.287/1.092 - 1.517, p = 0.003), whilst previous occurrence of cancer was not associated with SVR. Treatment adherence (76.0 vs. 72.0 %, p = 0.70) and the incidences of grade 3 or more adverse events (28.0 vs. 20.0 %, p = 0.40) were comparable between two groups. CONCLUSIONS Chronic hepatitis C patients with non-HCC malignancies receiving peginterferon/ribavirin combination therapy carried favorable efficacy and safety outcomes.

Abstract
Hepatitis C virus infection is a long-lasting disease, which causes chronic hepatitis, liver cirrhosis and hepatocellular carcinoma, thus leading to liver-related death. Currently, the optimal treatment for chronic hepatitis C infection is the combination of pegylated interferon and ribavirin. The aim of this review is to assess the long-term clinical outcomes of interferons alone or in combination with ribavirin in the management of chronic hepatitis C.

Abstract
Background The clearance of hepatitis C virus infection by interferon therapy significantly reduces the incidence of hepatocellular carcinoma and death in elderly chronic hepatitis patients. However, there are few reports concerning the efficacy and safety of pegylated interferon-alpha2b plus ribavirin combination therapy in elderly patients. The aims of the present study were to examine the effect and safety of pegylated interferon-alpha2b plus ribavirin combination therapy in 427 patients with chronic hepatitis C infection. We compared the rates of sustained virological response--defined as the absence of detectable hepatitis C virus in serum 24 weeks after the treatment ended--and the treatment discontinuation rate between 319 younger patients aged < 65 years and 108 elderly patients aged ≥ 65 years. We also examined the factors contributing to a sustained virological response. Results There was no significant difference in the sustained virological response rate between younger patients and elderly patients according to their hepatitis C virus genotype (41.5% (100/241) and 40.7% (35/86) for genotype 1; P = 0.899, 89.7% (70/78) and 86.4% (19/22) for genotype 2; P = 0.703, respectively). There was also no significant difference in the treatment discontinuation rate between the two age groups (10.3% (33/319) and 13.9% (15/108), respectively; P = 0.378). There were no serious adverse events requiring hospitalization. The factors contributing significantly to a sustained virological response in elderly patients were gender, hepatitis C virus genotype, platelet count, and the presence of a rapid or early virological response (undetectable hepatitis C virus in serum at weeks 4 or 12 of treatment, respectively). However, upon multivariate analysis, the presence of an early virological response was the only significant factor (odds ratio: 0.115, 95% confidence interval: 0.040- 0.330, P < 0.001). Conclusions The efficacy and safety of pegylated interferon-alpha2b plus ribavirin combination therapy in elderly patients are not always inferior to those in younger patients. Obtaining an early virological response may be essential to achieve a sustained virological response in elderly patients with chronic hepatitis C infection.

Abstract
The prevalence of chronic hepatitis C virus (HCV) tends to be higher in the elderly in many countries. Aging is regarded as an unfavorable factor for liver disease progression and treatment outcome in HCV infection. The efficacy and safety of treating elderly patients remain a source of significant debate. Discrepancies in results may be attributed to dissimilarities in study design and treatment regimens. The long-term benefits of administering interferon-based therapy to elderly patients with HCV infection is a critical issue when taking the patient's remaining life expectancy into consideration. Rapid virological response is the most notable on-treatment response factor that is predictive of treatment success in elderly patients. A shortened treatment course may reduce drug-related side effects and promote treatment adherence, especially in the elderly. A regimen tailored towards super-responders might provide insights for treatment strategies in elderly patients.

Abstract
For patients with chronic hepatitis C virus infection, the goal of antiviral therapy is to achieve a sustained virologic response (SVR). We review the durability of the SVR and its effects on liver-related mortality, hepatic decompensation, and the development of hepatocellular carcinoma. We performed a systematic review of the effects of the SVR on liver-related hepatic outcomes and found the SVR to be durable (range, 98.4%-100%). An SVR reduced liver-related mortality among patients with chronic hepatitis C (3.3- to 25-fold), the incidence of hepatocellular carcinoma (1.7- to 4.2-fold), and hepatic decompensation (2.7- to 17.4-fold). An SVR can lead to regression of fibrosis and cirrhosis, and has been associated with a reduced rate of hepatic decompensation, a reduced risk for hepatocellular carcinoma, and reduced liver-related mortality.

Abstract
AIM This study was conducted to clarify the incidence of hepatocellular carcinoma (HCC) and the factors contributing to its occurrence by following chronic hepatitis C patients who received pegylated interferon (PEG-IFN) α-2b plus ribavirin (RBV) combination therapy. METHODS Patients who received PEG-IFN α-2b and RBV combination therapy with no history of HCC or HCC within 3 months after the start of treatment were observed for the onset of HCC at 67 centers. RESULTS Sustained virological response (SVR) was observed in 999 (53.5%) of 1865 patients eligible for analysis. During the observation period (median duration: 4 years and 3 months), HCC developed in 59 patients (3.1%). A significant difference was observed in the 5-year cumulative incidence of HCC between SVR and non-SVR patients (1.1% vs. 7.1%). Factors contributing to HCC selected in multivariate analysis were therapeutic efficacy, sex, age, alanine aminotransferase (ALT) level at 24 weeks after the end of treatment, and platelet count. Non-SVR patients with ALT improvement after the end of treatment had a significantly lower 5-year cumulative incidence of HCC than those without (3.4% vs. 11.0%). HCC developed in 10 patients who achieved SVR, and multivariate analysis indicated that ALT level at 24 weeks after the end of treatment was the only significant factor contributing to HCC. CONCLUSION Several known risk factors for HCC contributed to HCC in patients who received PEG-IFN α-2b and RBV combination therapy, and ALT abnormality after the end of treatment contributes to the onset of HCC in both non-SVR and SVR patients.

Abstract
PURPOSE Peginterferon (PEG-IFN) and ribavirin (RBV) combination treatment for patients with chronic hepatitis C (CHC), infected by genotype-1 hepatitis C virus with high viral loads, results in a sustained viral response (SVR) in ~50%. However, a trend of decreasing SVR in the older patients has been reported. In the present study, we verified this trend of treatment efficacy in older patients using the propensity score (PS). METHODS We conducted a survey of 327 patients with CHC (genotype 1 and high viral loads) who were treated with PEG-IFN and RBV for 48 weeks. The SVR rate was compared between patients =60 and <60 years of age. Because backgrounds of these patients differed considerably, we verified this efficacy between the older (n = 102) and younger (n = 102) patients matched for gender, body weight, platelets (PLT), and red blood cell (RBC) counts using PS. RESULTS The total SVR rate was 42.9% (161/327); this rate decreased with increasing age and was lower in the older patients (≥60 years: 41.5%, <60 years: 54.3%, P = 0.0245). Moreover, younger age was a significant factor for SVR. After correction by PS, the SVR in older patients remained significantly lower (≥60 years: 43.1%, <60 years: 57.8%, P = 0.0497). In addition, RBC counts and hemoglobin (Hgb) concentrations, as well as RBV adherence in the older patients, decreased with this treatment, although there were no significant differences in pretreatment RBC and Hgb levels. CONCLUSIONS The analysis using PS indicated that RBV adherence in the older patients decreased even if they did not have lower pretreatment RBC and Hgb levels.

Sustained virologic response (SVR) is defined as aviremia 24 weeks after completion of antiviral therapy for chronic hepatitis C virus (HCV) infection. In analyses of SVR durability, the incidence of late relapse is extremely low (<1%). Histologic regression of both necroinflammation and fibrosis has been demonstrated in paired liver biopsy samples in SVR-achieving patients. More noteworthy is the sustained responder's favorable prognosis even with baseline cirrhosis; despite mostly retrospective analyses, relative to nonresponders or to those untreated, patients with SVR have significantly fewer liver-related complications, less hepatocellular carcinoma, and fewer liver-related deaths. Although HCV is associated with insulin resistance, successful eradication of HCV appears to reduce the risk of impaired fasting glucose and diabetes development. In summary, chronic HCV infection is curable with SVR attainment, and with cure comes improved liver histology and more favorable clinical outcomes, in comparison with patients who do not achieve the same therapeutic milestone.

Abstract
BACKGROUND AND AIM In the present study, we evaluated the safety and efficacy of combination therapy with pegylated interferon and ribavirin for treating chronic hepatitis C (CHC) patients aged 60 years and older. METHODS A total of 314 CHC patients, who were treated with combination therapy, were classified into three groups according to age: (i) younger than 50 years (n = 137); (ii) 50-59 years (n = 109); and (iii) 60 years or older (n = 68). The sustained virological response (SVR) and discontinuation rates were compared between the three groups. RESULTS Discontinuation of therapy due to adverse event was more frequent in the older patient groups: 1%, 5%, and 10% for the < 50-year, the 50-59-year, and the ≥ 60-year patient groups, respectively (P = 0.018). However, the older patient groups showed a SVR rate that was comparable to the SVR rates of the other age groups: 80%, 73%, and 75% for the < 50-year, 50-59-year, and ≥ 60-year- patient groups, respectively (P = 0.420). A multivariate analysis showed that the aspartate aminotransferase : platelet ratio index (APRI) was an independent predictor of an SVR. An SVR was achieved in 95% (19/20) of the elderly patients with an APRI < 0.80. CONCLUSIONS Although physicians must pay more attention to adverse events in the older patients, combination therapy can be considered for older patients, especially for patients with a low APRI.

Abstract
BACKGROUND Contraindications to interferon and ribavirin for treatment of chronic hepatitis C (CHC) are well recognized, and previous data indicated the consequent suboptimal treatment uptake. AIM To evaluate the treatment rate of CHC patients in a tertiary referral center in Hong Kong, and to examine the reasons for non-treatment. METHODS A retrospective review of all referred CHC patients to the outpatient clinic was conducted. Treatment uptake rate was evaluated and patients' sociodemographic, biochemical, and histological data were examined to identify reasons for treatment decision. RESULTS CHC patients (303) were assessed for antiviral therapy from 2000 to 2009. Of the patients, 138 (45.5%) did not receive antiviral therapy. Reasons for non-treatment were as follows: 31.9% declined treatment, 18.8% had decompensated cirrhosis, 12.3% were considered too elderly, 17.4% had too mild liver disease, 7.2% had psychiatric history, 7.2% had significant comorbidities, and 2.9% had ongoing alcohol or substance abuse. Independent factors associated with non-treatment were older age (adjusted odds ratio [aOR] 1.05, 95% confidence interval [CI] 1.03-1.08, p < 0.001), significant comorbidities (aOR 2.53, 95% CI 1.34-4.78, p = 0.004), psychiatric history (aOR 6.04, 95% CI 2.14-17.02, p < 0.001), mild liver disease (aOR 7.72, 95% CI 3.86-15.44, p < 0.001) and decompensated cirrhosis (aOR 9.42, 95% CI 2.57-34.50, p < 0.001). CONCLUSIONS Current treatment uptake for CHC patients was suboptimal, as a large proportion of patients were either reluctant for treatment or not suitable for the current antiviral therapy. Multidisciplinary interventions are needed in the short term while alternative antiviral therapy is desired in the long term to overcome barriers to treatment.

Abstract
AIM: To analyze the efficacy and safety of a combination therapy of pegylated interferon (PEG-IFN) α-2b plus ribavirin (RBV) in older Japanese patients (65 years or older) infected with hepatitis C virus (HCV).
METHODS: This multicenter study included 938 patients with HCV genotype 1 who received 1.5 μg/kg per week PEG-IFN α-2b plus RBV 600-1000 mg/d for 48 wk and 313 HCV genotype 2 patients who received this treatment for 24 wk.
RESULTS: At 24 wk after the end of combination therapy, the overall sustained virological response (SVR) for genotypes 1 and 2 were 40.7% and 79.6%, respectively. The SVR rate decreased significantly with age in each genotype, and was markedly reduced in genotype 1 (P < 0.001). Moreover, the SVR was significantly higher in patients with genotype 1 who were less than 65 years (47.3% of 685) than in those 65 years or older (22.9% of 253) (P < 0.001) and was higher in patients with genotype 2 who were less than 65 years (82.9% of 252) than in those 65 years or older (65.6% of 61) (P = 0.004). When patients received a dosage at least 80% or more of the target dosage of PEG-IFN α-2b and 60% or more of the target dosage of RBV, the SVR rate significantly increased to 66.5% in patients less than 65 years and to 45.2% in those 65 years or older (P < 0.001). Adverse effects resulted in treatment discontinuation more often in patients with genotype 1 (14.4%) than in patients with genotype 2 (7.3%), especially by patients 65 years or older (24.1%).
CONCLUSION: PEG-IFN α-2b plus RBV treatment was effective in chronic hepatitis C patients 65 years or older who completed treatment with at least the minimum acceptable treatment dosage.

Abstract
IMPORTANCE OF THE FIELD The issue of age in cases of chronic hepatitis C (HCV) in the West is a major problem; the average age of patients with HCV is increasing and its prevalence increases with advancing age. AREAS COVERED IN THIS REVIEW This review is devoted to the analysis of the limited number of clinical studies performed to treat HCV in elderly patients. WHAT THE READER WILL GAIN The importance of the age factor is outlined in nearly all the studies done in the field. Advanced age is associated with a lower sustained virologic response (SVR) rate. Moreover, in elderly patients, these studies also tend to suggest that, before initiating an antiviral treatment, the physician should not only take into account the classical parameters associated with SVR but also the presence of co-morbidities and life expectancy. TAKE-HOME MESSAGES: Antiviral therapy should be used in selected elderly HCV patients with advanced fibrosis and more studies are required in this population to better define the parameters associated with SVR. As age is an important factor in the success of antiviral therapy, starting antiviral treatment at a young age should be favored.

Abstract
OBJECTIVES The aim of this study was to evaluate the efficacy and indication of combination therapy with ribavirin plus peginterferon-alpha-2b in chronic hepatitis C virus (HCV) patients aged 65 years and older. METHODS Five hundred and ninety-one consecutive HCV patients were treated with combination therapy. These patients were divided into elder patients (> or = 65 years) (n=115) and younger patients (< 65 years) (n=476). The clinical characteristics, sustained virological response (SVR) rates and discontinuation rates were compared between the two groups. RESULTS Compared with younger patients, baseline haemoglobin levels and baseline platelet counts were significantly lower (P<0.0001, P=0.013 respectively) and fibrosis was more advanced in elderly patients (P=0.0310). Moreover, the SVR rate was significantly lower (37.4 vs. 51.5%; P=0.0067) while the combination therapy discontinuation rate was significantly higher (32.2 vs. 17.0%; P=0.0003) in elderly patients. A multivariate analysis revealed that HCV load and genotype were significantly associated with an SVR in elderly patients. An SVR was achieved in over 50% of elderly male patients with genotype 1 and HCV RNA concentrations under 2,000,000 IU/ml. In contrast, the SVR rate was under 30% in elderly male patients with genotype 1 and with HCV RNA concentrations over 2,000,000 IU/ml and in all elderly female patients with genotype 1. CONCLUSIONS The SVR rate was lower in elderly patients than in younger patients. However, in elderly patients combination therapy was most beneficial for genotype 1 patients, male patients with HCV RNA concentrations < 2,000,000 IU/ml and patients with genotype 2.

Abstract
IMPORTANCE OF THE FIELD Hepatitis C virus (HCV) is the main agent of chronic hepatitis, liver cirrhosis and hepatocellular carcinoma in the western world. It affects more than 170 million people worldwide. HCV treatment, based on the combination of Peg-interferon and ribavirin, is effective in about 50% of treated patients. Therefore, there is a need to develop new drugs active against HCV. AREAS COVERED IN THIS REVIEW Data were obtained by searching for all full articles on Medline and abstracts presented at major international congresses on viral hepatitis. WHAT THE READER WILL GAIN A review of clinical data about the efficacy and safety of telaprevir (VX-950), the HCV protease inhibitor that is in the most advanced phase of clinical development. TAKE HOME MESSAGE Telaprevir has an acceptable pharmacokinetic profile and seems to be a potent antiviral drug against HCV, although, owing to a low genetic barrier, resistant variants emerge within a few days when used in monotherapy, thereby decreasing its efficacy. Consequently, telaprevir has been combined with pegylated-interferon and ribavirin in clinical trials. This triple combination is more effective but has a higher rate of adverse events (notably rash) than the standard of care, despite the shorter duration of therapy.

Abstract
BACKGROUND The significance of antiviral therapy for elderly patients with chronic hepatitis C virus (HCV) infection has not been elucidated. PATIENTS AND METHODS Among 5645 patients with HCV-related chronic liver disease, the prognosis of 1917 elderly patients aged 60 years or more was analyzed. A total of 454 patients underwent interferon (IFN) therapy. By using multivariate analysis, carcinogenesis and survival were analyzed according to initial findings. RESULTS At 10 and 15 years, cumulative survivals in untreated elderly patients were 90.7% and 72.7% in the high platelet (>or=150,000/mm(3)) group, 78.6% and 47.8% in the intermediate (100,000-149,000/mm(3)) group, and 52.5% and 25.0% in the low platelet group (<100,000/mm(3)), respectively. At 5 and 10 years, hepatocarcinogenesis rates in the intermediate and low platelet groups were 10.9% and 21.6% in the IFN group (N=217) and 19.5% and 43.0% in the untreated group (N=459), respectively (P=.0005). IFN independently decreased carcinogenesis risk with a hazard ratio of 0.56 (P=.035). In the high platelet group, 5- and 10-year carcinogenesis rates were 3.7% and 8.3% in the IFN-treated group (N=228) and 5.1% and 14.0% in the untreated group (N=585), respectively (P=.69). IFN treatment significantly increased cumulative survivals in the lower platelet subgroup (P=.0001) but did not affect the higher platelet subgroup (P=.08). IFN was independently associated with a longer survival in the lower platelet subgroup (hazard ratio 2.33, P=.005). CONCLUSION In elderly patients with chronic HCV, IFN for a subgroup with intermediate and low platelet counts had significant advantages in regard to hepatocarcinogenesis and survival.

Abstract
Hepatitis C continues to be a major public health problem affecting approximately 3% of the global population. According to the World Health Organization, an estimated 170 million people have chronic hepatitis C. Ten percent to 20% of those who are chronically infected with hepatitis C will progress to cirrhosis and 5% will develop hepatocellular carcinoma. Although the safety and efficacy of hepatitis C therapies have been studied extensively in patients between the ages of 18 and 65, patients who are older than 65 still remain an understudied and difficult-to-treat population. This review discusses the epidemiology, natural history, and treatment of chronic hepatitis C in older adults.

Abstract
Hepatitis C virus (HCV) infection frequently occurs in elderly individuals, with a prevalence in individuals aged >60 years of up to approximately 40%. Although progression to cirrhosis is accelerated and occurs more frequently in patients who acquire the infection in old age, this outcome is often not seen because most elderly infected patients acquired HCV when they were young. Data on progression of HCV infection to cirrhosis and eventually to hepatocellular carcinoma are often derived from studies of HCV-infected individuals who present or are referred to hospitals, and which are therefore likely to overestimate the seriousness of the disease; indeed, population-based studies indicate that in many elderly individuals the disease is asymptomatic and runs a fairly benign course. Treatment is based on use of pegylated interferon-alpha and ribavirin, and is overall less effective and more toxic in the elderly. Therefore, treatment should be carefully considered on an individual basis and proposed only in patients up to the age of 75 years with a significant risk of progression of liver disease, no serious co-morbidities and good life expectancy. All treated patients should be followed long term in order to assess the influence of therapy on the evolution of liver disease (decompensated cirrhosis, hepatocellular carcinoma) and survival. It is hoped that liver biopsy, which is still required in order to assess prognosis appropriately, will be replaced in the future by less invasive methods based on combinations of biochemical markers of fibrosis and/or transient elastography, and that newer and less toxic orally administered drugs for HCV infection will become available.
