Retreatment with peginterferon alpha and ribavirin (PR) offers a limited chance of sustained virologic response (SVR) in patients who did not achieve SVR with prior PR treatment. This study evaluated the safety and efficacy of telaprevir-based treatment in combination with PR in well-characterized patients who did not achieve SVR in the control arms of three Phase II clinical trials. Patients eligible to enroll in this open-label nonrandomized study either met on-treatment criteria for nonresponse or relapsed after 48 weeks of treatment in the control arm of the three Phase II PROVE studies. The initial protocol was a 24-week regimen: 12 weeks of telaprevir and PR followed by an additional 12 weeks of PR. During the study the protocol was amended to extend PR to 48 weeks for patients with previous null response. All other patients with undetectable hepatitis C virus (HCV) RNA at weeks 4 and 12 received 24 weeks of therapy. Those with detectable HCV RNA at weeks 4 or 12 received a total of 48 weeks of therapy. The overall SVR rate was 59% (69/117). SVR rates with T12PR were 37% (19/51) in prior null responders, 55% (16/29) in prior partial responders, 75% (6/8) in prior breakthroughs, and 97% (28/29) in prior relapsers. The overall relapse rate was 16% (13/83). Adverse events were similar to those in previous trials with telaprevir, with 9% of patients discontinuing due to an adverse event (most commonly rash and anemia). CONCLUSION: This study demonstrated the benefit of retreatment with a telaprevir-based regimen for patients with well-characterized nonresponse (null and partial) or relapse to a prior course of PR treatment. 相似文献

We compared the background characteristics of patients with chronic hepatitis C who achieved eradication of hepatitis C virus (HCV), that is sustained virologic response (SVR), with interferon (IFN)‐based versus IFN‐free antiviral therapy in Japan. In addition, we used a previously reported risk assessment model to compare the incidence of hepatocellular carcinoma (HCC) after SVR by treatment type. Pretreatment characteristics of 1533 patients who achieved SVR with IFN‐based therapy and 1086 patients with IFN‐free therapy from five institutions across Japan were compared. The risk of HCC after SVR was assessed based on pretreatment characteristics, and the incidence of HCC after SVR was estimated in both groups. Age and serum alpha‐fetoprotein levels were higher, platelet count was lower, and liver fibrosis was more advanced in patients who achieved SVR with IFN‐free therapy compared with IFN‐based therapy. The incidence of HCC after SVR in the IFN‐free group was estimated to be more than twofold higher than in the IFN‐based therapy group (7.29% vs. 3.09%, and 6.23% vs. 3.01% when excluding patients who have underwent curative treatment for HCC). There are large differences in pretreatment characteristics between patients who achieved SVR with IFN‐based and IFN‐free therapies in Japan, which are associated with differential risk of HCC after SVR. These differences can influence the incidence of HCC after SVR and should be taken into consideration when comparing IFN‐based and IFN‐free therapies in terms of hepatocarcinogenesis suppression with HCV eradication. 相似文献

Chronic infection by hepatitis C virus (HCV) is one of the main risk factors for the
development of liver cirrhosis and hepatocellular carcinoma. However, the emergence
of hepatocellular carcinoma (HCC) in non-cirrhotic HCV patients, especially after
sustained virological response (SVR) is an unusual event. Recently, it has been
suggested that HCV genotype 3 may have a particular oncogenic mechanism, but the
factors involved in these cases as well as the profile of these patients are still
not fully understood. Thus, we present the case of a non-cirrhotic fifty-year-old
male with HCV infection, genotype 3a, who developed HCC two years after treatment
with pegylated-interferon and ribavirin, with SVR, in Brazil. 相似文献

BackgroundThe efficacy and safety of asunaprevir + daclatasvir combination therapy for treatment of hepatitis C virus (HCV) in compensated cirrhotic patients was not fully evaluated in real-world. Outcomes were assessed in cirrhotic patients with sustained viral response (SVR).Material and methodsA total of 145 patients without resistance-associated substitutions (RASs) at L31 and Y93 in the nonstructural protein 5A of HCV genotype 1b, consisting of 49 hepatic cirrhotic and 96 non-cirrhotic patients, were enrolled to the therapy. The patients were treated with 100 mg asunaprevir twice daily plus 60 mg daclatasvir once daily for 24 weeks. The primary endpoint was SVR 24 weeks after completing treatment. In addition, we evaluated the improvement of liver function and development of HCC for 1 year from the end of treatment (EOT).ResultsThe SVR24 rate was 96% (47/49) in the cirrhotic group and 96% (91/95) in the non-cirrhotic group (p = 0.69). During treatment, grade III/IV adverse events occurred more frequently in cir-rhotic patients (10/49; 20.4%) than in non-cirrhotic patients (10/96; 10.4%) (p = 0.099). After EOT, alanine aminotransferase and AFP levels were significantly decreased in cirrhotic patients with SVR. In addition, serum levels of albumin and platelet counts were significantly increased. On the other hand, the rates of HCC recurrence (43%) and development (7.4%) were higher in cirrhotic patients than in the non-cirrhotic patients (12.5% and 1.1%, respectively).ConclusionRAS-oriented asunaprevir/daclatasvir therapy has a strong anti-HCV effect in patients with HCV genotype 1b. However, careful management is necessary in patients with cirrhosis. 相似文献

AIM To clarify the prevalence of occult hepatitis B virus(HBV) infection(OBI) and the association between OBI and liver disease progression, defined as development of liver cirrhosis or hepatocellular carcinoma(HCC), worsening of Child-Pugh class, or mortality in cases of chronic hepatitis C virus(HCV) infection. METHODS This prospective cohort study enrolled 174 patients with chronic HCV infection(chronic hepatitis, n = 83; cirrhosis, n = 47; HCC, n = 44), and evaluated disease progression during a mean follow-up of 38.7 mo. OBI was defined as HBV DNA positivity in 2 or moredifferent viral genomic regions by nested polymerase chain reaction using 4 sets of primers in the S, C, P and X open reading frame of the HBV genome. RESULTS The overall OBI prevalence in chronic HCV patients at enrollment was 18.4%, with 16.9%, 25.5% and 13.6% in the chronic hepatitis C, liver cirrhosis and HCC groups, respectively(P = 0.845). During follow-up, 52 patients showed disease progression, which was independently associated with aspartate aminotransferase 40 IU/L, Child-Pugh score and sustained virologic response(SVR), but not with OBI positivity. In 136 patients who were not in the SVR state during the study period, OBI positivity was associated with neither disease progression, nor HCC development. CONCLUSION The prevalence of OBI in chronic HCV patients was 18.4%, and OBI was not associated with disease progression in South Koreans. 相似文献

Introduction and objectivesHepatitis C virus (HCV) infections in patients with hemophilia lead to the development of hepatocellular carcinoma (HCC) at a relatively younger age than that in patients without hemophilia. Although recent progress in direct-acting-antivirals has facilitated a high rate of sustained virological response (SVR), the clinical influence of HCV eradication in hemophilia patients remains unclear. This study aimed to compare the clinical outcomes of SVR against HCV in patients with and without hemophilia.Patients and methodsThe study enrolled 699 patients who achieved SVR after HCV antiviral treatment. Patients were divided into two groups: 78 patients with hemophilia (H group) and 621 patients without hemophilia (NH group). We evaluated patient characteristics, clinical outcomes, and the cumulative incidence of HCC after SVR.ResultsCompared with the NH group, patients in the H-group were significantly younger and had a lower hepatic fibrosis score. No difference was found in the incidence of liver-related disease or overall death between the two groups over a mean follow-up period of 7 years.Four patients in the H group and 36 patients in the NH group were diagnosed with HCC after SVR. Multivariate analysis showed that male sex, age, and cirrhosis were significant risk factors for HCC incidence. There was no significant difference in the cumulative incidence of HCC after propensity-score matching adjusting for the risk factors of HCC between the two groups.ConclusionHemophilia is not a significant risk factor for hepatocarcinogenesis after SVR against HCV. 相似文献

OBJECTIVES: To define the incidence of fibrosis progression among hepatitis C virus (HCV)/HIV-co-infected adults, to assess whether HCV or HIV treatment alters the risk of progression, and to determine the utility of liver biopsy to predict future disease. DESIGN: This prospective cohort evaluated 184 HIV/HCV-co-infected individuals who had at least two liver biopsies (median interval 2.9 years). METHODS: Biopsies were scored according to the Ishak modified histological activity index scoring system by a single pathologist blind to biopsy sequence. Significant fibrosis progression was defined as an increase of at least two Ishak fibrosis units between the first and second liver biopsy. Logistic regression analysis was used to assess determinants of fibrosis progression. RESULTS: A total of 174 non-cirrhotic patients were eligible; the majority were African-American men undergoing HIV treatment. On initial biopsy, no or minimal fibrosis was identified in 136 patients (77%). Significant fibrosis progression occurred in 41 patients (24%). Measures of HIV disease and its treatment before and after initial biopsy were not significantly different in progressors and non-progressors. Fibrosis progression was not associated with HCV treatment, which was received by 37 patients (21%) but only three sustained HCV-RNA suppression. In adjusted analysis, only an elevated serum aspartate aminotransferase level between biopsies was associated with progression (odd ratio 3.4, 95% confidence interval 1.4-7.9). CONCLUSION: Over a 3-year interval, significant fibrosis progression can occur in co-infected individuals even if minimal disease was detected on initial biopsy. In this context, factors other than treatment for HIV or HCV modify the risk of fibrosis progression. 相似文献

Abstract: Aim: The incidence of hepatocellular carcinoma (HCC) in C‐viral chronic hepatitis (CH) and liver cirrhosis (LC) patients after interferon (IFN) therapy was evaluated according to alanine aminotransferase (ALT) levels. Patients: Two hundred sixty‐nine patients with C‐viral CH and LC were treated with natural IFN‐α. The efficacy of IFN therapy was evaluated based on virologic response and ALT levels using the following groups: virologic‐sustained responders (VSR); biochemical‐sustained responders (BSR); partial responders (PR), which consisted of BSR patients whose serum ALT levels later relapsed; non‐responders (NR)1, which included patients with serum ALT levels that were usually less than 80 IU/l; and NR2, NR with ALT levels persistently more than 80 IU/l. Results: Of the 269 patients, 22 (8.2%) developed HCC after IFN therapy. The incidence of HCC (%/patient/year) was 0.78%, 0%, 0%, 0.17%, 4.68% in VSR, BR, PR, NR1, NR2, respectively. Multivariate analysis revealed that an increase in ALT levels to more than 80 IU/l is an important risk factor for the occurrence of HCC. Conclusions: We concluded that the patients with ALT levels less than twice the upper limit of normal after IFN therapy have a reduced risk of progression to HCC from C‐viral chronic liver disease. 相似文献

Summary. Antiviral treatment results in a sustained virologic response (SVR) in 50–75% of patients with chronic hepatitis C. Long-term follow up studies have observed ongoing SVR in the overwhelming majority of them. Thus chronic hepatitis C is considered 'cured' if an SVR is achieved. Consequently, it is expected that in sustained virologic responders long-term complications of hepatatic C virus (HCV) related chronic liver disease including hepatocellular carcinoma are eliminated or have a decreased incidence. We report on five patients (three from Austria, two from USA) who developed hepatocellular carcinoma during follow up (3–6 years) after achieving SVR. During follow up and at diagnosis all were HCV-RNA neg. None of the patients had other liver diseases. One patient presented with bilateral adrenal metastasis, the remaining four with large hepatic tumours. Three patients were noncirrhotic at the start of treatment at the time of tumour diagnosis. Successful antiviral treatment in HCV patients does not prevent development of hepatocellular carcinoma even in non-cirrhotic livers. Long-term follow up of patients with SVR is mandatory and should include surveillance for hepatocellular carcinoma. 相似文献

Long-term follow-up study of sustained biochemical responders with interferon therapy 总被引:3,自引:0,他引:3
A proportion of chronic hepatitis C patients who were treated with interferon have a sustained normalization of transaminase levels after interferon therapy without hepatitis C virus (HCV)-RNA clearance. We determined their clinical characteristics and long-term outcome in relation to progression to liver cirrhosis (LC) and the development of hepatocellular carcinoma (HCC). A total of 250 patients with chronic hepatitis C who were treated with interferon were studied for 8 to 11 years' posttherapy. Sixty-seven patients (27%) were complete responders with clearance of HCV RNA. Twenty-six (10%) were biochemical responders who had sustained normal alanine transaminase (ALT) levels without viral clearance. The remaining patients were short-term responders (n = 70) and nonresponders (n = 87). Biochemical responders were older, had higher levels of pretreatment HCV RNA in serum than complete responders, and had less advanced liver histology than nonresponders. Histologic grading scores decreased significantly at the end of therapy, while the staging scores did not change significantly. The annual incidence of cirrhosis was 0% in biochemical and complete responders, which was significantly lower than nonresponders and the controls (P = .0001). The annual incidence of HCC was 0.37% in complete responders and 0.50% in biochemical responders, which was significantly lower than nonresponders (P = .0001 for both). Our findings suggest that biochemical responders had high pretreatment viral levels with less advanced liver histology, and their long-term outcome appeared to be good irrespective of the persistence of the virus. 相似文献

AIM:To evaluate the histopathological findings of type C liver disease to determine risk factors for development of hepatocellular carcinoma(HCC).METHODS:We studied 232 patients,who underwent liver biopsy for type C chronic liver disease between 1992 and 2009,with sustained virological response(SVR)after interferon therapy.The patients were divided into two groups according to the F stage 0+1+2 group(n = 182)and F3+4 group(n = 50).We prospectively observed and compared the incidence of HCC of the patients with SVR in the F0+1+2 and F3+4 groups.Then,the background factors and liver histopathological findings,including the degree of fibrosis,F stage,inflammation,necrosis,bile duct obstruction,fat deposition,and degree of irregular regeneration(IR)of hepatocytes,were correlated with the risk of developing HCC.RESULTS:HCC developed in three of 182(1.6%)patients in the F0+1+2 group,and four of 50(8.0%)in the F3+4 group.The cumulative incidence of HCC in the former group was found to be significantly lower than in the F3+4 group(log rank test P = 0.0224).The presence of atypical hepatocytes among IR of hepatocytes in the F3+4 group resulted in a higher cumulative incidence of HCC,and was significantly correlated with risk of HCC development(RR = 20.748,95%CI:1.335-322.5,P = 0.0303).CONCLUSION:Atypical hepatocytes among the histopathological findings of type C liver disease may be an important risk factor for HCC development along with progression of liver fibrosis. 相似文献

BACKGROUND AND AIMS: Recent studies have suggested that bacterial coinfection with Helicobacter species in patients already infected with hepatitis C virus (HCV) could be involved in the development of cirrhosis and hepatocellular carcinoma (HCC). A retrospective cross sectional study was performed in order to explore the association between Helicobacter species and HCV associated liver diseases. METHODS: The presence of Helicobacter species was tested by polymerase chain reaction on liver samples from four groups of patients. RESULTS: Helicobacter 16S rDNA was found in only 4.2% of liver samples from control patients (n=24) and in 3.5% of liver samples from patients with non-cirrhotic chronic hepatitis C (n=29) while it was found in 68.0% of liver samples from patients with HCV positive cirrhosis without HCC (n=25) as well as in 61.3% of cirrhotic liver samples from patients with HCV positive cirrhosis and HCC (n=31). In addition, when the HCC tumour tissue was tested (n=21), 90.5% of samples were positive. DNA from Helicobacter pylori- and Helicobacter pullorum-like organisms was found. CONCLUSIONS: There is an association between the presence of Helicobacter species DNA in the liver and hepatitis C cirrhosis, with or without HCC. Indeed, the presence of these bacteria could be the result of structural changes in the liver. Alternatively, Helicobacter species could be a co-risk factor in HCV chronic liver diseases. This result warrants prospective studies to determine the possible causal role of these bacteria in the progression of chronic hepatitis C. 相似文献

Background and aimThe durability of the sustained virologic response (SVR) in patients with chronic hepatitis C after treatment and the ideal follow-up time for these patients remains undefined. The objective of the study was to evaluate the durability of the virologic response in patients with chronic hepatitis C followed up for at least 12 months after SVR at HCFMRP-USP.Methods: The study was conducted on 174 patients with chronic hepatitis C treated with different antiviral regimens who had achieved SVR. Qualitative serum HCV-RNA was determined by the commercial kit (COBAS AMPLICOR HCV, v2.0).ResultsThere was predominance of male (73%) with a mean age of 45.6 ± 10 years. Liver cirrhosis was present in 16.1% of the study subjects. Mean follow-up time after SVR was 47 months (12-156 months). Twenty-two patients received monotherapy with interferon; 94 received interferon plus ribavirin, and 58 received pegylated interferon plus ribavirin. A total of 134 patients (77.0%) received one treatment course, 29 (16.7%) received two courses, and 11 (6.3%) received three courses. The distribution of HCV genotypes was: genotype 1 (40.2%), genotype 3 (40.8%) and genotype 2 (10.3%). Genotype was undetermined in 8.7% of cases. None of the 174 patients had recurrence of HCV infection. Two cirrhotic patients developed hepatocellular carcinoma (HCC) during follow-up.ConclusionsAmong patients with SVR there was no recurrence of HCV infection or evidence of liver disease progression in any patient followed up for a mean of 47 months after SVR, except for patients with advanced hepatic disease before treatment, who may develop HCC despite SVR. Therefore, one can assume that SVR is associated with long term good prognosis. 相似文献

Background & Aims
Daclatasvir has achieved high sustained virologic response (SVR) rates in diverse hepatitis C virus (HCV) populations. This study evaluated the long‐term efficacy and safety of daclatasvir‐based regimens administered during clinical studies.Methods
Patients enrolled within 6 months of parent study completion or protocol availability at the study sites. The primary objective was durability of SVR at follow‐up Week 12 (SVR12). Secondary objectives included analysing HCV sequences in non‐responders or responders who relapsed, and characterization of liver disease progression.Results
Between 24 February 2012 and 17 July 2015, this study enrolled and began following 1503 recipients of daclatasvir‐based regimens (follow‐up cut‐off, 13 October 2015); 60% were male, 18% aged ≥65 years, 87% had genotype‐1a (42%) or ‐1b (45%) infection, and 18% had cirrhosis. Median follow‐up from parent study follow‐up Week 12 was 111 (range, 11‐246) weeks. 1329/1489 evaluable patients were SVR12 responders; 1316/1329 maintained SVR until their latest visit. Twelve responders relapsed by (n = 9) or after (n = 3) parent study follow‐up Week 24; one was reinfected. Relapse occurred in 3/842 (0.4%) and 9/487 (2%) responders treated with interferon‐free or interferon‐containing regimens, respectively. Hepatic disease progression and new hepatocellular carcinoma were diagnosed in 15 and 23 patients, respectively. Among non‐responders, emergent non‐structural protein‐5A (NS5A) and ‐3 (NS3) substitutions were replaced by wild‐type sequences in 27/157 (17%) and 35/47 (74%) patients, respectively.Conclusions
SVR12 was durable in 99% of recipients of daclatasvir‐based regimens. Hepatic disease progression and new hepatocellular carcinoma were infrequent. Emergent NS5A substitutions persisted longer than NS3 substitutions among non‐responders. 相似文献16.

BACKGROUND AND AIM: Hepatitis C virus (HCV)-infected patients who responded to interferon (IFN) treatment with clearance of serum HCV RNA may rarely develop hepatocellular carcinoma (HCC). The aim of the present study was to elucidate the risk factors for liver carcinogenesis among such patients. METHODS: In total, 126 patients with chronic hepatitis C (CHC) who achieved a sustained virological response (SVR) to IFN monotherapy, which was defined as the absence of detectable HCV RNA in the serum at 6 months after completion of treatment, were enrolled and possible risk factors for HCC were analyzed. RESULTS: During the observation period of 66 +/- 36 months after cessation of IFN treatment, five (4.0%) of the 126 patients developed HCC. The cumulative incidence of HCC at 3, 5 and 10 years was estimated to be 0.9, 4.7 and 7.5%, respectively. The cumulative incidence of HCC was significantly higher among patients with severe fibrosis (F3 or F4) than among patients with no or mild fibrosis (F0 to F2) in the liver before treatment (P = 0.007); among patients with alcohol intake of > or = 27 g/day than among patients with that of < 27 g/day (P = 0.015); and among patients who were > or = 65 years old than among patients who were < 65 years old at the start of treatment (P = 0.026). CONCLUSIONS: Patients with CHC who had severe fibrosis, who had regularly taken moderate amounts of alcohol, or who were > or = 65 years at the start of IFN treatment should be carefully followed to detect small and controllable HCC, even after eradication of HCV. 相似文献

Background and aimsSevere liver disease markers assessed before HCV eradication are acknowledged to usually improve after the SVR. We prospectively evaluated, in the PITER cohort, the long-term HCC risk profile based on predictors monitored after HCV eradication by direct-acting antivirals in patients with cirrhosis.MethodsHCC occurrence was evaluated by Kaplan-Meier analysis. Cox regression analysis identified the post-treatment variables associated with de-novo HCC; their predictive power was presented in a nomogram.ResultsAfter the end of therapy (median follow-up:28.47 months), among 2064 SVR patients, 119 (5.8%) developed de-novo HCC. The HCC incidence was 1.90%, 4.21%, 6.47% at 12-, 24- and 36-months from end-of-therapy, respectively (incidence rate 2.45/100 person-years). Age, genotype 3, diabetes, platelets (PLT)≤120,000/µl and albumin ≤3.5g/dl levels were identified as pre-treatment HCC independent predictors. Adjusting for age, the post-treatment PLT≤120,000/µl (AdjHR 1.92; 95%CI:1.06-3.45) and albumin≤3.5g/dl (AdjHR 4.38; 95%CI 2.48-7.75) values were independently associated with HCC occurrence. Two different risk profiles were identified by combining long-term post-therapy evaluation of PLT ≤ vs. >120,000/µl and albumin ≤ vs. >3.5g/dl showing a significant different HCC incidence rate of 1.35 vs. 3.77/100 p-y, respectively.ConclusionsThe nomogram score based on age, PLT and albumin levels after SVR showed an accurate prediction capability and may support the customizing management for early HCC detection. 相似文献

Background/Aims: The present study aimed to assess the incidence of advanced cirrhotic complications and to identify the risk factors associated with such complications in chronic hepatitis C. Methods: The data of 1137 chronic hepatitis C patients were retrospectively reviewed. We analysed the incidence rate and risk factors for ‘disease progression’, as defined by the occurrence of an increase of at least 2 points in the Child–Pugh score, oesophageal/gastric variceal bleeding, spontaneous bacterial peritonitis, hepatic encephalopathy, death related to liver disease or development of hepatocellular carcinoma (HCC). Results: Of the 1137 patients enrolled for analysis, 490 patients received antiviral treatment. The overall annual incidence rate of disease progression was 0.8 and 3.7% for patients with and without antihepatitis C virus (anti‐HCV) therapy respectively. The development of HCC was the most common cause of disease progression. In patients with anti‐HCV therapy, treatment response, platelet level and aspartate aminotranferase:platelet ratio index (APRI) were independent factors associated with disease progression. For those without anti‐HCV therapy, older age, male sex, diabetes, platelet level and APRI were independent factors for disease progression. APRI was strongest predictor for disease progression. Conclusions: The present study demonstrated that the development of HCC was the most common cause of disease progression, and we also identified the risk factors associated with disease progression. Thus, patients at such risks need close monitoring for disease progression, and especially for detecting HCC. Moreover, the active application of antiviral therapy and efforts to improve the antiviral response are required. 相似文献

Hepatitis C virus (HCV) chronic infection is associated with fibrosis progression, end-stage liver complications and HCC. Not surprisingly, HCV infection is a leading cause of liver-related morbidity and mortality worldwide. After sustained virological response (SVR), the risk of developing hepatocellular carcinoma is not completely eliminated in patients with established cirrhosis or with advanced fibrosis. Therefore, lifelong surveillance is currently recommended. This strategy is likely not universally cost-effective and harmless, considering that not all patients with advanced fibrosis have the same risk of developing HCC. Factors related to the severity of liver disease and its potential to improve after SVR, the molecular and epigenetic changes that occur during infection and other associated comorbidities might account for different risk levels and are likely essential for identifying patients who would benefit from screening programs after SVR. Efforts to develop predictive models and risk calculators, biomarkers and genetic panels and even deep learning models to estimate the individual risk of HCC have been made in the direct-acting antiviral agents era, when thousands of patients with advanced fibrosis and cirrhosis have reached SVR. These tools could help to identify patients with very low HCC risk in whom surveillance might not be justified. In this review, factors affecting the probability of HCC development after SVR, the benefits and risks of surveillance, suggested strategies to estimate individualized HCC risk and the current evidence to recommend lifelong surveillance are discussed. 相似文献

Background and Aims: African Americans (AA) historically have a low response rate to hepatitis C therapies, and there is limited information available for this patient population regarding the development and treatment of chronic hepatitis C (CHC). The aim of this study was to evaluate liver disease progression and hepatocellular carcinoma (HCC) development in AA with CHC. Methods: Between 1995 and 2008, 246 AA patients with CHC were identified from a database of patients and followed until 2012-2013 (average 8 years) or the development of HCC after 2008. Results: Viral clearance (intent to treat; sustained virus response (SVR)) was achieved in 15% of patients with interferon based therapies with or without ribavirin. AA patients who achieved an SVR (n=22) did not develop HCC or new onset cirrhosis, whereas the HCC incidence in untreated AA patients was 23% (51/203). Patients who achieved an SVR also had improved fibrosis, as defined by the AST Platelet Ratio Index (APRI) and Fibrosis-4 (FIB-4) score, relative to nonresponders and untreated patients. Conclusions: The severity of liver disease at the first visit (except for cirrhosis) correlated with the development of HCC, but because of the overlap in values between patients, these measurements were not useful for predicting individual risk. Since cirrhosis at the first visit was not a predictive factor, treatment with newer antiviral therapies is the best option for reducing the incidence of advanced liver disease and its harmful outcomes in the AA population. 相似文献
