Sirinawasatien A, Supawan P. Sustained virological response in chronic hepatitis C patients by direct-acting antiviral treatment significantly reduces liver stiffness over 24 weeks posttreatment. Medicine (Baltimore) 2024; 103:e38096. [PMID: 38728473 PMCID: PMC11081621 DOI: 10.1097/md.0000000000038096] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/31/2024] [Accepted: 04/11/2024] [Indexed: 05/12/2024] Open
Abstract
To investigate whether direct-acting antiviral (DAA) treatment affected liver fibrosis testing, including transient elastography (TE), aspartate aminotransferase-to-platelet ratio index (APRI), and Fibrosis-4 (FIB-4) index, after establishing a sustained virological response for 24 weeks. This prospective cohort study was conducted between October 1, 2019, and September 30, 2020, at Rajavithi Hospital, Bangkok, Thailand. All the patients had significant liver fibrosis (TE ≥ 7.0 kPa) at baseline and completed 12 weeks of DAA therapy. After achieving SVR, liver stiffness measurements were repeated for at least 24 weeks. The primary outcome was a > 30% improvement in TE score at the end of the study compared to baseline. A multivariate logistic regression model was used to identify the parameters associated with the primary outcome. Temporal changes in APRI and FIB-4 indices from baseline to 24 weeks posttreatment were also examined. A total of 110 chronic HCV patients were included in our cohort, of which 57 (52.3%) achieved the primary outcome. The median TE decreased from 15.05 (8.76-23.68) kPa at pretreatment to 9.60 (6.50-14.40) kPa at 24 weeks posttreatment (P < .001). Those who had a baseline TE ≥ 9.5 kPa had higher odds of meeting the primary outcome, and this remained significant after adjusting for age, sex, baseline body mass index, underlying diabetes mellitus, HCV genotype 3, baseline laboratory levels, and treatment regimens (OR 3.04; 95% CI 1.22-7.60, P = .017). Similar to TE, the median APRI and FIB-4 index displayed a considerable reduction from baseline to 24 weeks after successful therapy. Modern DAA treatment has been associated with considerable improvement in liver stiffness measured by TE in chronic HCV patients who achieve SVR, with roughly 52% of patients experiencing a reduction of > 30% in TE over 24 weeks posttreatment compared to baseline. This probably indicates early fibrosis regression, although the effect of resolution of inflammation after treatment completion cannot be ruled out.

Abstract
BACKGROUND It is unclear whether hepatocyte function and/or portal hypertension improves if a sustained virologic response (SVR) is achieved with direct-acting antivirals in patients with decompensated hepatitis C-related cirrhosis. METHODS We examined the safety and efficacy of a 12-week course of sofosbuvir/velpatasvir (SOF/VEL) in 20 patients with decompensated hepatitis C-related cirrhosis. We also investigated changes in the hepatocyte receptor index (LHL15) and blood clearance index (HH15) by Tc-99 m-galactosyl human serum albumin scintigraphy, liver stiffness measurement (LSM) by transient elastography, and hepatic venous pressure gradient (HVPG) in patients who achieved an SVR at 24 weeks after treatment (SVR24). RESULTS One patient discontinued treatment because of rectal variceal hemorrhage, and 19 patients completed treatment. SVR24 was achieved in 17 patients (89%). Median LHL15 increased from 0.72 pre-treatment to 0.82 after SVR24 (p = 0.012), and median HH15 decreased from 0.82 pre-treatment to 0.76 after SVR24 (p = 0.010). The percentage of patients with LSM ≥ 20 kPa was 90% before treatment and remained at 90% after SVR24. However, the percentage with severe portal hypertension (defined as HVPG ≥ 12 mmHg) decreased from 92% pre-treatment to 58% after SVR24 (p = 0.046). Patients with a decreased HVPG from pre-treatment to after SVR24 had a smaller pre-treatment spleen volume than those with an increased HVPG (median, 252 vs. 537 mL, p = 0.028). CONCLUSION Achieving SVR24 with SOF/VEL treatment in patients with decompensated hepatitis C-related cirrhosis can be expected to improve hepatocyte function and portal hypertension on short-term follow-up.

Orr CE, Wang PL, Chen L, Wang T. Features of fibrosis regression abound in “non-cirrhotic” patients with resected hepatocellular carcinoma. PLoS One 2022; 17:e0267474. [PMID: 35552548 PMCID: PMC9098014 DOI: 10.1371/journal.pone.0267474] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2021] [Accepted: 04/08/2022] [Indexed: 11/18/2022] Open
Abstract
Cirrhosis is a major risk factor for developing hepatocellular carcinoma (HCC). However, many surgically resected HCCs are presumably non-cirrhotic. The dynamic nature of chronic liver disease leads to periods of hepatic repair and fibrosis regression. We hypothesize that most resected HCCs, including those from non-cirrhotic patients, exhibit features of fibrosis regression in their background liver, suggesting previously more advanced liver disease. We reviewed the histology of 37 HCC resections performed between 2005–2020, including 30 from non-cirrhotic patients. The non-neoplastic liver was evaluated for features of liver disease and of the hepatic repair complex (HRC). CD34 immunohistochemistry was performed as a marker of sinusoidal capillarization. CD34 staining was evaluated manually and also by a digital image classifier algorithm. Overall, 28 cases (76%) had a high number of fibrosis regression and hepatic repair features (≥4 out of 8 features). Amongst the 30 non-cirrhotic patients, 21 (70%) showed a high number of repair features. Relative CD34 expression was increased in cases with a high number (≥4) of HRC features versus a low number (≤3) of features (p = 0.019). High HRC cases were more likely to exhibit nodular circumferential CD34 staining (p = 0.019). Our findings suggest that most resected HCC from non-cirrhotic patients display features of fibrosis regression in their background liver. Thus many, if not most, HCC patients who are “non-cirrhotic” may in fact have regressed cirrhosis. This finding reinforces that patients with regressed cirrhosis continue to be at high risk for HCC.

Different kinetics of liver stiffness using shear wave elastography in patients with chronic hepatitis C infection treated with interferon-free regimens. Eur J Gastroenterol Hepatol 2019; 31:67-74. [PMID: 30239347 DOI: 10.1097/meg.0000000000001259] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 12/15/2022]
Abstract
BACKGROUND Direct-acting antivirals (DAAs) lead to a high rate of sustained virologic response (SVR) in chronic hepatitis C infection. The aim was to evaluate liver stiffness kinetics, using acoustic radiation force impulse (ARFI) imaging elastography, during and after DAAs in patients who had reached SVR. PATIENTS AND METHODS A total of 275 consecutive chronic hepatitis C virus-infected patients were included in this longitudinal prospective single-centre study. All patients received DAAs for 8 to 24 weeks, and liver stiffness measurements (LSMs) by ARFI at baseline, at week 4, week 12, week 24, and 24 weeks (SVR24) and 48 weeks (FU48) after the end of treatment were recorded. Transient elastography was performed at baseline and at SVR24. RESULTS A decrease in LSM was detected at SVR24 by ARFI and transient elastography (P<0.001 and <0.001, respectively). A continuous gradual decrease in ARFI was observed in patients with cirrhosis versus a nonsignificant change in patients without cirrhosis until FU48 (P<0.001 vs. 0.877, respectively). At SVR24, higher baseline ARFI values (P=0.038) were associated with a decrease in LSM in patients with cirrhosis versus normal international normalization ratio (P=0.003), lower bilirubin (P=0.003), and higher albumin (P=0.007) in patients without cirrhosis. The incidence of liver stiffness decrease from baseline was higher in patients with cirrhosis than in those without cirrhosis (P<0.001), whereas the incidence of liver stiffness progression was more pronounced in advanced than in compensated cirrhosis (P<0.001). CONCLUSION After DAAs in patients with SVR, liver stiffness improves in patients with cirrhosis, whereas non-cirrhotic patients show no true change in liver stiffness. Liver stiffness worsens in patients with advanced liver disease.

Abstract
BACKGROUND The improvement in liver histology is an important aim in the management of hepatitis C virus (HCV) infection. Previous studies suggest that antiviral treatment could reduce the progression of hepatic fibrosis, especially in patients with sustained virological response (SVR). However, most studies were limited by short-term evaluations and the liver stiffness was assessed by non-invasive methods. In our study, we performed a paired liver biopsy study aimed at analyzing the long-term histological changes in patients with SVR. METHODS We included 31 patients who had been previously treated with peginterferon plus ribavirin. All patients achieved SVR and had received pre- and post-treatment liver biopsies. The histological appearance of fibrosis and inflammation were assessed with METAVIR scoring system and Histological Activity Index (HAI) criteria. We analyzed several factors associated with the histological response. RESULTS The median interval between two biopsies was 93.0 months. The percentage of patients with fibrosis regression, stable, and progression were 19%, 45%, and 36%. A total of 71% of patients achieved inflammation improvement, whereas 6% and 23% of patients had stable disease and disease-progression, respectively. We showed that the patients without baseline advanced fibrosis and those having a lower baseline HAI score had higher risk of fibrosis worsening. Baseline fibrosis and necroinflammation status did not influence HAI change significantly. CONCLUSION The progression of hepatic fibrosis and inflammation can be reversed in some patients who had long-term virological suppression. Patients with advanced baseline fibrosis and higher inflammatory stages seemed to receive more histologic benefit from successful antiviral treatments.

Abstract
BACKGROUND AND AIM In patients with HCV-related cirrhosis, a sustained virological response may lead to cirrhosis regression. Whether histological changes translate into prevention of long-term complications, particularly hepatocellular carcinoma is still unknown. This was investigated in a cohort of histological cirrhotics who had been prospectively followed-up for 10 years after the achievement of a sustained virological response to IFN. METHODS In all, 38 sustained virological response cirrhotics who underwent a liver biopsy 5 years post-SVR were prospectively followed to assess the impact of cirrhosis regression on clinical endpoints. RESULTS During a follow-up of 86 (30-96) months from liver biopsy, no patients developed clinical decompensation, whilst 5 (13%) developed hepatocellular carcinoma after 79 (7-88) months. The 8-year cumulative probability of hepatocellular carcinoma was 17%, without differences between patients with or without cirrhosis regression (19% [95% CI 6%-50%] vs 14% [95% CI 4%-44%], P = .88). Patients who developed or did not an hepatocellular carcinoma had similar rates of residual cirrhosis (P = 1.0), collagen content (P = .48), METAVIR activity (P = .34), portal inflammation (P = .06) and steatosis (P = .17). At baseline, patients who developed an hepatocellular carcinoma had higher γGT (HR 1.03, 95% CI 1.00-1.06; P = .014) and glucose (HR 1.02, 95% CI 1.00-1.02; P = .012) values; moreover, they had increased Forns Score (HR 12.8, 95% CI 1.14-143.9; P = .039), Lok Index (HR 6.24, 95% CI 1.03-37.6; P = .046) and PLF (HR 19.3, 95% CI 1.72-217.6; P = .016) values. One regressor died of lung cancer. The 8-year cumulative survival probability was 97%, independently on cirrhosis regression (96% vs 100%, P = 1.0) or hepatocellular carcinoma (100% vs 97%, P = 1.0). CONCLUSIONS Post-SVR cirrhosis regression does not prevent hepatocellular carcinoma occurrence.

Hytiroglou P, Theise ND. Regression of human cirrhosis: an update, 18 years after the pioneering article by Wanless et al. Virchows Arch 2018; 473:15-22.

Abstract
Cirrhosis has been traditionally viewed as an irreversible, end-stage condition. Eighteen years ago, Wanless, Nakashima, and Sherman published a study that was based on the concept that hepatic architecture is under constant remodeling in the course of chronic liver diseases, even during their most advanced stages; depending on the balance between injury and repair, the histologic changes might be progressing or regressing. These authors described in detail the morphologic features of regressing cirrhosis, identified a set of histologic features of regression that they called the "hepatic repair complex," and provided convincing morphologic evidence that incomplete septal cirrhosis represents regressed cirrhosis. In the years that followed publication of this pioneering article, a number of clinical studies with performance of pre- and post-treatment liver biopsies provided abundant evidence that cirrhosis can regress after successful therapy of chronic hepatitis B, chronic hepatitis C, autoimmune hepatitis, and genetic hemochromatosis. Evidence for other chronic liver diseases may also be provided in the future, pending ongoing studies. Successful therapy allows resorption of fibrous septa, which can be followed by loss of nodularity and architectural improvement; however, many vascular lesions of cirrhotic livers are not thought to regress. Cases of cirrhosis that are considered more likely to improve than others include those of recent onset, with relatively thin fibrous septa and mild vascular changes. Histologic examination of liver biopsy specimens from patients with chronic liver diseases provides the opportunity to appreciate the features of the hepatic repair complex on a routine diagnostic basis; however, interpretation is often difficult, and can be aided by immunohistochemical stains. Clinicopathologic correlation is essential for a meaningful assessment of such cases. For many patients, cirrhosis is not an end-stage condition anymore; therefore, use of the term "cirrhosis" has been challenged, almost 200 years after its invention. However, regression of cirrhosis does not imply regression of molecular changes involved in hepatocarcinogenesis; therefore, surveillance for hepatocellular carcinoma should be continued in these patients.

Abstract
BACKGROUND & AIMS The effect of direct-acting-antivirals (DAA) on coagulation of hepatitis-C-virus (HCV)-related cirrhosis is unknown. METHODS We investigated 28 patients on DAA treatment and performed prothrombin-time, thrombin generation with and without thrombomodulin, whole-blood thromboelastometry, as well as the individual procoagulants (II, VIII, XIII, von Willebrand) and anticoagulants, antithrombin and protein-C. RESULTS Patients had undetectable HCV-RNA at the end-of- treatment and at 12-weeks after end-of-treatment (sustained virological response). Transaminases were significantly decreased at both end-of-treatment and at 12-weeks. Prothrombin-time declined at 12-weeks, but did not reach statistical significance. Factor-II, protein-C and antithrombin increased significantly at end-of-treatment (P<.001) and persisted at 12-weeks. Factor-VIII decreased at end-of-treatment and to a greater extent at 12-weeks when reached statistical significance (P<.05). Factor-VIII/protein-C ratio decreased sharply, reached statistical significance at end-of-treatment (P<.01) and persisted at 12-weeks. Von-Willebrand decreased at end-of-treatment and reached statistical significance at 12-weeks (P<.001). Endogenous-thrombin-potential without thrombomodulin increased significantly at end-of-treatment (P<.01) and persisted at 12-weeks. No changes were observed after addition of thrombomodulin. Endogenous-thrombin-potential ratio (with/without thrombomodulin) decreased and reached statistical significance at 12-weeks (P<.05). Thromboelastometry clotting time decreased sharply, reached statistical significance at end-of treatment (P<.001) and persisted at 12-weeks. CONCLUSIONS Treatment with DAAs in HCV-related cirrhosis results in improvement of the individual pro- and anticoagulants. It can be hypothesised that the net effect does not substantially modify their balance (as shown by the unchanged thrombin generation in the presence of thrombomodulin) but makes it more stable and less amenable to be perturbed as presumably occurs before treatment when there is a partial deficiency for both.

Liver fibrosis can regress in patients with chronic hepatitis in whom the underlying cause of liver damage is adequately treated. Studies documenting this benefit have been mostly performed in the setting of viral hepatitis, particularly hepatitis C virus, where sustained viral response has been unequivocally shown to result in histological and clinical improvement. With the advent of the new IFN-free regimens, highly effective and safe even in those historically considered "difficult to treat and cure patients," additional benefits have been documented in patients treated at advanced stages of disease, including improvement in liver function with hepatic "recompensation," reduction of portal hypertension, and eventually avoidance of liver transplantation. Disease reversibility has been also demonstrated in the posttransplant setting and appears to be similar to what is observed in the nontransplant patient.

Abstract
There is great geographical variation in the distribution of hepatocellular carcinoma (HCC), with the majority of all cases worldwide found in the Asia–Pacific region, where HCC is one of the leading public health problems. Since the “Toward Revision of the Asian Pacific Association for the Study of the Liver (APASL) HCC Guidelines” meeting held at the 25th annual conference of the APASL in Tokyo, the newest guidelines for the treatment of HCC published by the APASL has been discussed. This latest guidelines recommend evidence-based management of HCC and are considered suitable for universal use in the Asia–Pacific region, which has a diversity of medical environments.

Abstract
BACKGROUND AND AIM Virological cure becomes available for most patients with chronic hepatitis C (CHC), but residual fibrosis can be an independent risk factor for liver-related complications. We aimed to characterize fibrosis change in CHC patients achieved virological cure. METHODS We did a systematic literature search for studies that had pre and post-treatment evaluations of histologic fibrosis in CHC patients with sustained virological response (SVR). We identified the association of SVR with the incidence, extent, and velocity of fibrosis change. RESULTS Overall, 3243 patients were included. Interferon-based regimens were used for all the patients, achieving a median SVR prevalence of 36.2%. Biopsy interval ranged from 1 to 10 years. Mean baseline fibrosis score (METAVIR) was 2.3 points. Compared with non-SVR patients, SVR patients could have higher incidence of fibrosis regression (35.1% vs 17.0%; OR: 3.3; P < 0.001), regardless of baseline fibrosis severity, way of biopsy evaluation, treatment regimen, or study design, and could have more extent of reduction (-0.31 points vs -0.00 points; P = 0.004). Baseline advanced fibrosis (F > 2) was associated with more rapid regression in both SVR and non-SVR patients (P < 0.05 for both). SVR patients could have lower incidence of fibrosis progression and maintenance than non-SVR patients by 4.8% versus 23.1% (OR: 0.20; P = 0.008) and 42.9% versus 55.2% (OR: 0.53; P < 0.001), respectively. CONCLUSIONS There could be a favorable characteristic of fibrosis regression in SVR patients. However, residential fibrosis may remain an issue because of a non-ignorable prevalence of fibrosis maintenance among these patients.

Abstract
BACKGROUND HIV/HCV co-infected patients show accelerated fibrosis progression and higher risk for complications of portal hypertension (PHT). AIM To assess the effects of interferon-free therapy on portal pressure, liver histology and plasma biomarkers in HIV/HCV-coinfected patients with PHT. METHODS Twenty-two patients with paired hepatic venous pressure gradient (HVPG) measurements prior and after successful treatment (SVR) with interferon-free regimens were included. Liver stiffness was assessed by transient elastography and biopsies were scored according to METAVIR. Plasma biomarkers were determined by ELISA. RESULTS Overall, HVPG decreased from 10.7 ± 4.1 mmHg at baseline to 7.4 ± 4.2 mmHg after HCV treatment (Δ:-3.3 ± 2.7 mmHg; p < 0.001). In patients with clinically significant PHT (HVPG≥10 mmHg, n = 11), HVPG decreased from 14.1 ± 2.9 to 10.4 ± 3.9 mmHg (Δ:-3.7 ± 3.3 mmHg; p = 0.004) and a haemodynamic response (HVPG decrease ≥10%) was observed in 73%. In 64% of patients with subclinical PHT (HVPG 6-9 mmHg, n = 11), portal pressure normalised at SVR. Mean liver stiffness decreased from 20.8 kPa to 11.5 kPa (Δ:-8.8 ± 7.4 kPa; p < 0.001). Fifty percent (7/14) of patients with cirrhosis were re-classified as METAVIR ≤F3 and all patients with decompensated cirrhosis improved their Child-Pugh stage. After successful HCV treatment, 39% still had persistent histological necroinflammatory activity (METAVIR A1), which correlated with less HVPG response and more steatosis. While most biomarkers improved with SVR, METAVIR A1 patients had significantly higher plasma levels of fibrogenic (PDGF, TGF-β) and angiogenic (VEGF, Angiopoietin1) biomarkers. CONCLUSIONS Interferon-free therapy reduces PHT and halts histological necroinflammatory activity in the majority of HIV/HCV-coinfected patients after SVR, which may lead to re-compensation of liver function in cirrhosis. Biomarkers could identify patients with persisting hepatic necroinflammation.

Abstract
There is little data on the long-term follow-up outcomes of chronic hepatitis C patients achieving sustained virological response (SVR) after treatment with peglylated interferon-α plus ribavirin. We prospectively investigated the overall clinical, biochemical, virological and histological outcomes in a ten-year cohort study of 325 patients with chronic hepatitis C achieving SVR to pegylated interferon-α and ribavirin therapy. Patients underwent consistent clinical, biochemical and virological evaluation every six months, and patients with pretherapy Ishak fibrosis score ≥2 were invited to accept a second liver biopsy at the last follow-up. Liver biopsy specimens were evaluated using Ishak's scoring system. At the end of follow-up, five patients developed decompensated liver cirrhosis. One patient (0.3%) with pretherapy cirrhosis was diagnosed with hepatocellular carcinoma (HCC). A total of 305 patients (94%) had normal serum ALT and AST levels during the entire period of follow-up. Twenty-seven patients (8%) had conclusive evidence of virological relapse. Among the 117 patients with paired pretherapy and long-term follow-up biopsies, 96 (82%) had a decreased fibrosis score. Ninety-nine (79%) had a decrease in combined inflammation score. Thirty-seven (32%) had normal or nearly normal livers on long-term follow-up biopsy. SVR achieved with PEG-IFN-α and RBV combination therapy is durable, while late virological relapse may still occur in some patients. Clinical outcomes for patients who obtain SVR are excellent, although the patients with cirrhosis are still at a low risk of hepatocellular carcinoma.

Evidence-based clinical practice guidelines for liver cirrhosis 2015. J Gastroenterol 2016; 51:629-50.

Abstract
The Japanese Society of Gastroenterology revised the evidence-based clinical practice guidelines for liver cirrhosis in 2015. Eighty-three clinical questions were selected, and a literature search was performed for the clinical questions with use of the MEDLINE, Cochrane, and Igaku Chuo Zasshi databases for the period between 1983 and June 2012. Manual searching of the latest important literature was added until August 2015. The guidelines were developed with use of the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system. This digest version in English introduces selected clinical questions and statements related to the management of liver cirrhosis and its complications. Branched-chain amino acids relieve hypoalbuminemia and hepatic encephalopathy and improve quality of life. Nucleoside analogues and peginterferon plus ribavirin combination therapy improve the prognosis of patients with hepatitis B virus related liver cirrhosis and hepatitis C related compensated liver cirrhosis, respectively, although the latter therapy may be replaced by direct-acting antivirals. For liver cirrhosis caused by primary biliary cirrhosis and active autoimmune hepatitis, urosodeoxycholic acid and steroid are recommended, respectively. The most adequate modalities for the management of variceal bleeding are the endoscopic injection sclerotherapy for esophageal varices and the balloon-occluded retrograde transvenous obliteration following endoscopic obturation with cyanoacrylate for gastric varices. Beta-blockers are useful for primary prophylaxis of esophageal variceal bleeding. The V2 receptor antagonist tolvaptan is a useful add-on therapy in careful diuretic therapy for ascites. Albumin infusion is useful for the prevention of paracentesis-induced circulatory disturbance and renal failure. In addition to disaccharides, the nonabsorbable antibiotic rifaximin is useful for the management of encephalopathy. Anticoagulation therapy is proposed for patients with acute-onset or progressive portal vein thrombosis.

Abstract
BACKGROUND AND AIM Liver biopsy (LB) has lost popularity to stage liver fibrosis in the era of highly effective anti-hepatitis C virus (HCV) therapy, yet diagnosis of persistent cirrhosis may have important implications following HCV eradication. As performance of serological non-invasive tests (NITs) to predict residual fibrosis in non-viremic HCV patients is unknown, we investigated accuracy of NITs to predict residual fibrosis in cirrhotics after a sustained virological response (SVR) to interferon (IFN). METHODS Thirty-eight patients with a pre-treatment histological diagnosis of cirrhosis and a 48-104 months post-SVR LB were tested with APRI, CDS, FIB-4, FibroQ, Forns Score, GUCI Index, King Score, Lok Index, PLF, ELF. In 23 (61%) patients, cirrhosis had histologically regressed. RESULTS All NITs values declined after SVR without any significant difference between regressors and non-regressors (AUROC 0.52-0.75). Using viremic cut-offs, PPV ranged from 34% to 100%, with lower NPV (63% - 68%). NITs performance did not improve using derived cut-offs (PPV: 40% - 80%; NPV: 66% - 100%). PLF, which combines several NITs with transient elastography, had the best diagnostic performance (AUROC 0.75, Sn 61%, Sp 90%, PPV 80%, NPV 78%). After treatment, none of the NITs resulted significantly associated with any of the histological features (activity grade, fibrosis stage, area of fibrosis). CONCLUSIONS The diagnostic estimates obtained using both viremic and derived cut-off values of NITs were suboptimal, indicating that none of these tests helps predicting residual fibrosis and that LB remains the gold standard for this purpose.

Abstract
Surveillance of hepatocellular carcinoma (HCC) with abdominal ultrasound (US) is recommended for patients with advanced liver fibrosis because of hepatitis C virus (HCV) infections who achieve a sustained virological response (SVR) to antiviral therapy. HCC, in fact, may still develop following SVR as a consequence of long-standing carcinogenic activity of either HCV or hepatic fibrosis, whereas HCC risk in non-viraemic patients may also be driven by cofactors like alcohol abuse or diabetes. This explains the debate on whether surveillance for HCC should be continued in patients with documented cirrhosis regression following a SVR too. While regression of cirrhosis was documented to occur in a majority of patients with compensated cirrhosis 5 years after an SVR to interferon, it should be noted that this clinical benefit could be the consequence of treating a selected population with well-compensated liver disease who in fact were interferon able. This may not be the case for most real-life patients with advanced cirrhosis receiving direct antivirals, in whom liver fibrosis may have reached a point of no-return thus potentially preventing the recovery of a normal liver architecture following SVR. Both invasive and non-invasive tools have suboptimal diagnostic accuracy for fibrosis regression in non-viraemic patients, and this prompts to follow international societies' recommendation to perform surveillance in patients with advanced liver fibrosis achieving a SVR, independently on liver histology outcome.

Abstract
BACKGROUND Opportunities to treat infection with hepatitis C virus (HCV) are evolving rapidly. From the introduction of interferon (IFN)-α monotherapy in the early 1990s to the approval of telaprevir- and boceprevir-based triple therapies with pegylated (PEG)-IFN-α and ribavirin (RBV) in 2011, the chances of curing patients infected with HCV genotype 1 have improved dramatically to reach approximately 70%. Significant further improvements that may cure virtually all HCV patients with an all-oral, IFN-free regimen are becoming progressively available. Key Messages: Historically, a PEG-IFN/RBV combination therapy of patients with liver cirrhosis was associated with lower virological rates and a worse safety profile. The advent of the first protease inhibitor-based triple therapy was long expected, but the promise fell rapidly because of the numerous side effects and the requirement for intensive clinical management in cirrhotic patients. The newer direct-acting antivirals (DAAs) target the viral polymerase with either nucleos(t)ide analogues or nonnucleosidic inhibitors, the viral protease and the viral NS5A protein. Several clinical trials have now shown that a combination of sofosbuvir (nucleosidic polymerase inhibitor) with daclatasvir or ledipasvir (NS5A inhibitors), or sofosbuvir with simeprevir (protease inhibitor), or a combination of ABT-450 (protease inhibitor) with ritonavir (ABT-450/r), the nonnucleosidic polymerase inhibitor ABT-333 and the NS5A inhibitor ABT-267, can achieve a sustained virological response in up to 95% of naive patients or previously treated patients, even in those who failed prior treatment with first-generation protease inhibitors. The best treatment regimens enable the achievement of comparable results even in cirrhotics, while other regimens still require RBV or a longer treatment duration to achieve optimal results. This improved risk/benefit ratio justifies early access programs of IFN-free regimens for cirrhotic patients. The remaining difficult-to-treat patients are cirrhotics infected with HCV genotype 3 and those with decompensated cirrhosis, for whom novel DAA combinations should be evaluated in clinical trials. CONCLUSIONS As new DAAs are becoming available in early access treatment programs, treatment strategy studies are being performed to optimize treatment regimens with respect to the choice of DAAs and treatment duration, based on viral genotypes, prior treatment response and the presence of liver cirrhosis. In the near future, this should allow: (i) a decrease in the complications of HCV-induced cirrhosis, (ii) liver transplantations to be performed in virally cured patients, and (iii) the rescue of patients in the worst clinical situation (decompensated cirrhosis and HCV recurrence on liver graft).

Abstract
Patients with advanced hepatic fibrosis or cirrhosis with chronic hepatitis C virus (HCV) infection represent an unmet need. The HCV NS3/4A inhibitor, faldaprevir, was evaluated in combination with the nonnucleoside NS5B inhibitor, deleobuvir, with or without ribavirin in treatment-naive patients with HCV genotype 1 infection in the SOUND-C2 study. Here, the efficacy and safety of this interferon-free regimen in a subset of patients with advanced liver fibrosis, including those with compensated cirrhosis, were assessed. Patients (n=362) were randomized to once-daily faldaprevir with either twice-daily (BID) or three-times-daily (TID) deleobuvir for 16 (TID16W), 28 (TID28W and BID28W), or 40 (TID40W) weeks with or without ribavirin (TID28W-NR). Patients were classified according to fibrosis stage (F0 to F2 versus F3 to F4) and the presence of cirrhosis (yes/no). In total, 85 (24%) patients had advanced fibrosis/cirrhosis (F3 to F4) and 33 (9%) had cirrhosis. Within each treatment arm, differences in rates of sustained virologic response 12 weeks after completion of treatment (SVR12) between patients with mild to moderate fibrosis (F0 to F2) versus F3 to F4 did not show a consistent pattern and were not statistically significant (63% versus 47% for TID16W, 53% versus 76% for TID28W, 48% versus 67% for TID40W, 70% versus 67% for BID28W, and 40% versus 36% for TID28W-NR, respectively; P > 0.05 for each arm). The most frequent adverse events in patients with/without cirrhosis were gastrointestinal and skin events, which were mostly mild or moderate in intensity. The degree of liver fibrosis did not appear to affect the probability of achieving SVR12 following treatment with the interferon-free regimen of faldaprevir, deleobuvir, and ribavirin.

Abstract
BACKGROUND & AIMS Liver stiffness (LS) measurement using transient elastography allows for accurate evaluation of liver fibrosis in patients with chronic liver disease. We aimed to investigate the influence of antiviral treatment using entecavir (ETV) on LS values in patients with chronic hepatitis B (CHB). METHODS 121 patients with CHB who completed a 3-year ETV treatment were recruited. LS values were measured before starting ETV (baseline) and after the completion of the 3-year treatment. A significant decline in the LS value was defined as a ≥30% drop from the baseline. RESULTS The median baseline LS value of the patients was 14.3 kPa. However, it decreased significantly to 7.3 kPa after 3-year ETV treatment (P < 0.001). A higher baseline LS value was the single independent predictor of a significant decline in LS value on multivariate analysis (P<0.001; hazard ratio [HR], 1.155; 95% confidence interval [CI], 1.073-1.243). Using an optimal cutoff baseline LS value of 11.5 kPa (area under receiver operating characteristic curve, 0.781; 95% CI, 0.698-0.863, P < 0.001; sensitivity 75.6%; specificity, 62.8%), patients with baseline LS values of ≥11.5 kPa had a greater probability of experiencing a significant decline in the LS value than those with baseline LS values of <11.5 kPa (P < 0.001; HR, 5.240; 95% CI, 2.340-11.732). CONCLUSIONS In patients with CHB, LS values were decreased significantly after a 3-year ETV treatment. A higher baseline LS value was the single independent predictor of a significant decline in the LS value.

Abstract
AIM To evaluate the association between liver stiffness measured by acoustic radiation force impulse (ARFI) elastometry and the outcome of antiviral treatment in patients with chronic viral hepatitis B and C. MATERIALS AND METHODS Thirty-eight patients with chronic viral hepatitis B (n = 16) or hepatitis C (n = 22) underwent liver biopsy and ARFI elastometry of the right hepatic lobe. A follow-up assessment using ARFI was performed a mean of 2.3 years after the baseline evaluation. The patients with favourable outcome were classified in group S and those receiving no treatment, showing no response to treatment, or experiencing a relapse were classified in group N. RESULTS The 38 patients had an initial mean ARFI value of 1.56 ± 0.62 m/s as compared with 1.54 ± 0.64 m/s in the follow-up evaluation. Group S showed a significant decline in ARFI values (1.55 ± 0.60 m/s versus 1.34 ± 0.47 m/s; p < 0.05) and included 16 (64%) patients with lower shear wave velocities at follow-up. In group N, liver stiffness values showed a slight but not significant increase (1.57 ± 0.70 m/s versus 1.93 ± 0.77 m/s). CONCLUSION Changes in liver stiffness during antiviral therapy can be assessed by ARFI reflecting response or no response. ARFI elastometry is an additional, useful tool for the follow-up assessment of treatment outcome in patients with chronic viral hepatitis B or C infection.

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 The widely-accepted treatment outcome for chronic hepatitis C is the sustained viral response (that is, no measurable viral RNA in blood six months after treatment). However, this surrogate outcome (as well as the previously employed biochemical and histologic ones) has never been validated. This situation exists because there are very few randomized clinical trials that have used clinical events (mortality or manifestations of decompensated cirrhosis) as outcomes, because those clinical events only occur after many years of infection. Patients in whom initial therapy fails to produce sustained viral responses do become potential candidates for retreatment; some of these individuals are not candidates for ribavirin or protease inhibitors and consideration could be given to retreatment with interferon alone. OBJECTIVES To assess the benefits and harms of interferon monotherapy retreatment in chronic hepatitis C patients and to validate the currently employed surrogate outcomes in this group of patients. SEARCH METHODS We searched The Cochrane Hepato-Biliary Group Controlled Trials Register, the Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library, MEDLINE, EMBASE, and Science Citation Index Expanded until 16 August 2012. SELECTION CRITERIA Randomized trials comparing interferon versus placebo or no treatment in chronic hepatitis C nonresponders and relapsers to previous interferon. DATA COLLECTION AND ANALYSIS The primary outcomes were mortality (all-cause and hepatic), quality of life, and adverse events. Secondary outcomes were liver-related morbidity, sustained viral responses, biochemical responses, histologic improvements, and costs. We used both fixed-effect and random-effects model meta-analyses, reporting only the former if no difference existed. MAIN RESULTS Seven trials were identified. Two of them were at low risk of bias (the HALT-C and EPIC3 trials) and included 1676 patients. Both of these trials addressed the role of long-term low-dose pegylated interferon therapy in patients with severe fibrosis (demonstrated on liver biopsy) and were designed to assess the clinical outcomes. The remaining five trials included 300 patients and were at high risk of bias. Based on all trials reporting the outcomes, no significant difference was observed in either all-cause mortality (78/843 (9.3%) versus 62/867 (7.2%); risk ratio (RR) 1.30, 95% confidence interval (CI) 0.95 to 1.79; 3 trials) or hepatic mortality (41/532 (7.7%) versus 40/552 (7.2%); RR 1.07, 95% CI 0.70 to 1.63; 2 trials); however, when only the two trials at low risk of bias were combined, all-cause mortality was significantly higher in the recipients of the pegylated interferon (78/828 (9.4%) versus 57/848 (6.7%); RR 1.41, 95% CI 1.02 to 1.96) although trial sequential analysis could not exclude the possibility of random error. There was less variceal bleeding in the recipients of the interferon (4/843 (0.5%) versus 18/867 (2.1%); RR 0.24, 95% CI 0.09 to 0.67; 3 trials), although again trial sequential analysis could not exclude the presence of a type I error and the effect could not be confirmed in a random-effects model meta-analysis. No significant differences were seen with regard to the development of ascites, encephalopathy, hepatocellular carcinoma, or the need for liver transplantation. One trial reported quality of life data; the pain score was significantly worse in the recipients of the pegylated interferon. Adverse effects tended to be more common in the interferon recipients; the ones that were significantly more common included hematologic complications, infections, flu-like symptoms, and rash. The recipients of interferon had significantly more sustained viral responses (20/557 (3.6%) versus 1/579 (0.2%); RR 15.38, 95% CI 2.93 to 80.71; 4 trials) and a type I error was excluded by trial sequential analysis. The METAVIR activity score also improved (36/55 (65%) versus 20/46 (43.5%); RR 1.49, 95% CI 1.02 to 2.18; 2 trials). No significant differences were seen with regard to histologic fibrosis assessments. AUTHORS' CONCLUSIONS The clinical data were limited to patients with histologic evidence of severe fibrosis who were retreated with pegylated interferon. In this scenario, retreatment with interferon did not appear to provide significant clinical benefit and, when only the trials at low risk of bias were considered, retreatment for several years may even have increased all-cause mortality. Such treatment also produced adverse events. On the other hand, the treatment did result in improvement in some surrogate outcomes, namely sustained viral responses and histologic evidence of inflammation. Interferon monotherapy retreatment cannot be recommended for these patients. No clinical data are available for patients with less severe fibrosis. The sustained viral response cannot be used as a surrogate marker for hepatitis C treatment in this clinical setting with low sustained viral response rates and needs to be validated in others in which higher sustained viral response rates are reported.

Abstract
BACKGROUND Protease inhibitors have improved sustained virological response (SVR) rates for subjects with genotype 1 hepatitis C virus infection (HCV). There is however uncertainty regarding how, and in whom, these agents should be used. In previously treated subjects, prior response to interferon has a major effect on SVR rates with protease inhibitor therapy. AIM To assess the benefits of treatment and to understand the utility of a stopping rule for subjects with a poor interferon response following a 4-week lead-in with pegylated interferon and ribavirin. METHODS Treatment responses and long-term outcomes were modelled using hypothetical 1000 subject cohorts with 5 years of follow-up. Treatment strategies were compared with number needed to treat (NNT) and comparative effectiveness approaches. RESULTS Over 5 years of follow-up the NNT to prevent liver-related mortality for subjects with advanced fibrosis was substantially lower than that for subjects with all fibrosis stages (18 vs. 60) indicating particular benefit in this high-risk population. The use of a stopping rule for subjects with advanced fibrosis and a poor interferon response after a 4-week lead-in reduces the number of subjects exposed to a protease inhibitor by 55%. However, 33% fewer liver-related deaths are prevented using this strategy, indicating that there is unacceptable harm associated with this approach over a 5-year follow-up period. CONCLUSIONS Subjects with advanced fibrosis should be prioritised for triple therapy on the basis of need. Treatment should be continued regardless of initial interferon response to maximise the early prevention of hepatitis C virus-related mortality.

Abstract
UNLABELLED Although annular fibrosis is the hallmark of cirrhosis, other microscopic changes that affect liver function such as sinusoid capillarization or loss of metabolic zonation are common. A sustained virological response (SVR) may halt fibrosis deposition in hepatitis C virus (HCV)-infected patients, but its impact on the other cirrhosis-associated lesions is unknown. The aim of this study was to assess the impact of an SVR on cirrhosis-related histopathological features. Paired pre- and posttreatment liver biopsies from 38 HCV patients with cirrhosis with an SVR were analyzed. Fibrosis was staged using the METAVIR scoring system, and the area of fibrosis was measured using morphometry. Ductular proliferation, metabolic zonation, sinusoid capillarization, and hepatic stellate cell activation were assessed by anti-cytokeratin-7, anti-glutamine synthetase (GS), anti-cytochrome P4502E1 (CYP2E1), anti-CD34, and anti α-smooth muscle actin (αSMA). After 61 months from an SVR, cirrhosis regression was observed in 61%, and the collagen content decreased in 89%. Although periportal and lobular necroinflammation vanished, portal inflammation persisted in 66%. Ductular proliferation decreased in 92%. Before treatment, metabolic zonation was lost, as shown by GS and CYP2E1, in 71% and 88%, respectively, with normalization in 79% and 73%, after an SVR. Conversely, no changes in sinusoidal capillarization were observed after treatment, as assessed by CD34 (P = 0.41) and αSMA (P = 0.95). Finally, no differences in all the immunohistochemical scores emerged whether or not cirrhosis persisted. CONCLUSION Cirrhosis regression and decreased fibrosis are frequently observed among HCV patients with cirrhosis with an SVR. Despite ductular proliferation vanishing and lobular zonation restoration, portal inflammation and sinusoidal capillarization may not regress after viral eradication.

Abstract
Antiviral treatment of chronic hepatitis C virus (HCV) is aimed at the persistent eradication of the virus, the so-called sustained virological response (SVR), with the aim ultimately being to prevent the development of liver-related complications and improve patients' survival. Patients with HCV-related compensated cirrhosis are the group most likely to benefit from viral clearance, as several retrospective studies have shown liver complications rates to be positively modified by the achievement of a SVR. Whether these benefits rely on viral clearance or on the histological improvements seen following successful interferon (IFn)-based therapies has recently been a matter for debate, as studies have shown cirrhosis to regress in some patients with a SVR. Whatever the mechanisms, cirrhosis has the uncanny ability to be both a dominant indication for therapy, as well as one of the strongest baseline factors associated with reduced efficacy of any IFn-based regimen. This has led to the development of alternative treatment strategies, such as low dose pegylated IFn (PegIFn) monotherapy, that unfortunately has proven to be of limited efficacy. For this reason regimens able to clear the virus without relying on the broad antiviral effect of IFN are eagerly awaited.

Abstract
Chronic hepatitis C virus (HCV) infection is the main cause of liver cirrhosis and liver carcinoma in western countries. There is evidence that HCV clearance induced by antiviral therapy is beneficial, increasing survival and reducing the complications of cirrhosis. Triple therapy with boceprevir or telaprevir associated with pegylated interferon and ribavirin has increased rates of sustained viral response both in treatment-naïve patients and in those failing previous regimens. Before treating patients with these new molecules, physicians should be familiar with their indications and the regimens to be used. Furthermore, both adverse events and the development of resistances must be monitored. The main aims are careful selection of patients and of the regimen to be used, and achieving adequate adherence to obtain optimal results.

Abstract
BACKGROUND Transient elastography measures liver stiffness, which correlates with the hepatic fibrosis stage and has excellent accuracy for the diagnosis of cirrhosis in patients with chronic hepatitis C. AIM To assess prospectively the kinetics of liver stiffness in treated patients with chronic hepatitis C and compare them with the viral kinetics on treatment and with the final outcome of therapy. METHODS 91 patients with chronic hepatitis C with significant fibrosis (>7.0kPa) at baseline were included. They received therapy with pegylated interferon-α and ribavirin. The kinetics of liver stiffness were characterized during therapy and thereafter by means of Fibroscan, and compared with the virological responses at weeks 4, 12, 24, end of treatment and 12 and 24weeks after. RESULTS A significant liver stiffness decrease was observed during therapy, which continued after treatment only in patients who achieved a sustained virological response. In this group, the median intra-patient decrease relative to baseline at the end of follow-up was -3.4kPa, vs-1.8kPa in the patients who did not achieve an SVR. Similar dynamics were observed in cirrhotic and non-cirrhotic patients. In multivariate analysis, only the SVR was associated with long-term improvement of liver stiffness (odds ratio: 3.10; 95% confidence interval: 1.20-8.02, P=0.019). CONCLUSIONS In patients with advanced fibrosis at the start of therapy, liver stiffness is significantly reduced during treatment, but improvement continues off treatment only in patients who achieve a sustained virological response. Liver stiffness assessment earlier than 6months after the end of therapy does not appear to be clinically meaningful.

Abstract
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 Cirrhosis developing during chronic infection with the hepatitis C virus (HCV) poses a risk of anticipated liver-related death, therefore representing a dominant indication to anti-HCV therapy. OBJECTIVE This review highlights the efficacy and safety of treatment of HCV infection in cirrhotic patients with respect to the clinical stage of the disease. METHODS The PubMed, MEDLINE, EMBASE, and Cochrane databases, as well as the conference proceedings from the annual meetings of the American Association for the Study of Liver Diseases, the European Association for the Study of the Liver, and the Asian Pacific Association for the Study of the Liver, were searched for articles published in English from January 1990 through May 2010, fulfilling the following criteria: (1) randomized, prospective observational, retrospective, or meta-analysis; (2) involving adult patients with chronic HCV infection; and (3) data (fibrosis stage, treatment regimen, efficacy, safety) available for cirrhotics. Reviews were excluded. Search terms included chronic hepatitis C, fibrosis, cirrhosis, interferon alfa, ribavirin, hepatocellular carcinoma, and liver decompensation. RESULTS Forty-five studies were identified. The rates of sustained virologic response to pegylated interferon in combination with ribavirin ranged from 10% to 44% for HCV genotypes 1/4 to 33% to 72% for genotypes 2/3 in compensated cirrhosis, while falling to 0% to 16% and 44% to 57%, respectively, in the decompensated stage, compared with 29% to 55% for genotypes 1/4 and 70% to 80% for genotypes 2/3 in noncirrhotic patients (compensated cirrhosis vs no cirrhosis: P < 0.001 for genotypes 1/4 and P = 0.002 for genotypes 2/3; decompensated cirrhosis vs no cirrhosis: P < 0.001 for all genotypes). HCV clearance was associated with a reduced risk of liver decompensation, hepatocellular carcinoma development, liver-related mortality, and hepatitis recurrence after liver transplantation. Treatment during compensated cirrhosis proved to be most cost-effective versus treatment after decompensation or a no-treatment strategy. Headache (54%), irritability (38%), fatigue (34%), and nausea (30%) were the most common adverse events in compensated patients, while anorexia (100%), fatigue (59%), neutropenia (53%), and thrombocytopenia (50%) were most common in decompensated patients. CONCLUSIONS Anti-HCV treatment in cirrhotic patients was less effective than in noncirrhotic patients. Viral eradication reduced the risk of liver complications and improved survival in noncirrhotics. Based on effectiveness and tolerability data, therapy has a significant effect in patients with compensated cirrhosis, while decompensated patients need to weigh the risks versus benefits of treatment.

Abstract
Treatment of patients with hepatitis-B-related or hepatitis-C-related decompensated cirrhosis should focus on controlling the complications of cirrhosis, surveillance for hepatocellular carcinoma and, if applicable, preparation for orthotopic liver transplant. Interferon-based regimens for the treatment of hepatitis C have been somewhat successful in patients with cirrhosis, although treatment of patients with decompensated cirrhosis should be approached with caution. Given the potential for exacerbation of decompensation and poor tolerance of adverse effects, treatment should be reserved for those patients awaiting liver transplantation. Eradication of HCV before liver transplantation reduces the chances of recurrent hepatitis C infection after transplant. HBV can be treated with few adverse effects in patients with decompensated cirrhosis. This treatment is associated with improvement in decompensation in some patients. Hepatocellular carcinoma remains a significant risk in all patients with cirrhosis, and control of or eradication of HBV or HCV does not remove this risk.

Abstract
OBJECTIVES We sought to compare the histologic response, safety, and tolerability in Latino and non-Latino patients with hepatitis C virus (HCV) genotype 1 treated with peginterferon α-2a plus ribavirin (LATINO study). METHODS LATINO was a prospective, open-label, multicenter study that enrolled 269 Latinos and 300 non-Latinos receiving peginterferon α-2a 180 μg/week and ribavirin 1,000/1,200 mg/day for 48 weeks. Liver biopsies were obtained within 18 months of baseline and at week 72. Improved or worsened liver fibrosis and necroinflammatory activity were assessed by the Ishak-modified histologic activity index scoring system. Efficacy and safety parameters were monitored during treatment and the 24-week follow-up period. RESULTS The primary study results published elsewhere showed a higher sustained virologic response (SVR) rate among non-Latinos than Latinos (49% vs. 34%; P<0.001). Paired biopsy data were available for 157 Latinos and 201 non-Latinos. At baseline, more Latinos vs. non-Latinos had alanine aminotransferase (ALT) >3 × the upper limit of normal (20% vs. 18%) and cirrhosis (13% vs. 10%). Both groups experienced improvement in Ishak activity at week 72, although the improvement rates were higher in non-Latinos than Latinos (59% vs. 47%; P=0.03). For both groups, more patients with SVR compared with non-responders had improved Ishak fibrosis scores. In both groups, baseline Ishak activity score (P<0.0001 for both) was predictive of Ishak activity response. Additional predictors in Latinos were age (P=0.0023), body mass index (BMI) (P=0.068), baseline ALT quotient (P=0.031), and baseline Ishak fibrosis scores (P=0.021). There were no significant differences in steatosis changes between the two groups. Adverse events (AEs) and withdrawals due to AEs were more frequent in non-Latinos. CONCLUSIONS Significant proportions of patients in both groups had histologic response to peginterferon α-2a plus ribavirin. However, histologic response was higher in non-Latinos than in Latinos regardless of virologic response. This study highlights the need for additional strategies to improve virologic response in Latinos.

Abstract
UNLABELLED Patients with chronic hepatitis C with partial virologic response or nonresponse to interferon-based therapies can experience treatment-related improvements in liver histology. This retrospective analysis assessed the histologic response to treatment in patients with varying degrees of virologic response (sustained virologic response [SVR], breakthrough, relapse, or nonresponse), time to hepatitis C virus (HCV) RNA undetectability, and duration of viral suppression. Patients (HCV genotypes 1-6) with baseline and follow-up liver biopsies from eight phase 2 to phase 4 interferon-based trials were analyzed. Blinded biopsies were evaluated by a single pathologist. Improvements or worsening of METAVIR necroinflammatory activity and fibrosis were defined as increase or decrease of ≥1 grading category from baseline to 24 weeks after end of treatment. A majority of the 1571 patients with paired biopsy data were white, male, with HCV genotype 1/4, baseline HCV RNA levels >800,000 IU/mL, and baseline alanine aminotransferase levels ≤3 × upper limit of the normal range; mean baseline activity and fibrosis scores were 1.8 and 1.7, respectively. Overall, 80% of patients received peginterferon alfa-2a monotherapy or peginterferon alfa-2a/ribavirin combination therapy. Mean treatment duration was 46 weeks. There was a positive correlation between the degree of virologic response and improvements in METAVIR activity and fibrosis, and an inverse correlation with worsening activity and fibrosis (all comparisons, P < 0.0001). Patients with SVR had the greatest histologic benefit. As a combined group, relapsers and patients with breakthrough had significantly greater benefits than nonresponders (activity, P = 0.0001; fibrosis, P = 0.003). Consistent with these results, a better histologic response was correlated with a shorter time to undetectable HCV RNA and a longer duration of viral suppression (all comparisons, P < 0.0001). CONCLUSION In patients with chronic hepatitis C who were treated with interferon-based therapies, histologic benefits may be observed even in the absence of an SVR.

Long-term effects of antiviral therapy in patients with chronic hepatitis C. HEPATITIS RESEARCH AND TREATMENT 2010; 2010:562578. [PMID: 21188198 PMCID: PMC3003987 DOI: 10.1155/2010/562578] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 06/22/2010] [Accepted: 07/25/2010] [Indexed: 02/06/2023]
Abstract
Chronic hepatitis C is a major cause of chronic liver disease globally, and the natural history of progression may lead to cirrhosis with liver failure, hepatocellular carcinoma, and premature liver-related death. Emerging data demonstrates that interferon-based therapy, particularly among those achieving a sustained virologic response (SVR), is associated with long-term persistence of SVR, improved fibrosis and inflammation scores, reduced incidence of hepatocellular carcinoma, and prolonged life expectancy. This reduction in the rate of progression has also been demonstrated in patients with chronic hepatitis C and cirrhosis in some but not all studies. The majority of these results are reported with standard interferon therapy, and long-term results of peginterferon plus ribavirin therapy with a higher likelihood of SVR should have a yet greater impact on the population of treated patients. The impact on slowing progression is greatest in patients with an SVR, less in relapsers, and equivocal in nonresponders. Thus, the natural history of chronic hepatitis C after completion of antiviral therapy is favorable with achievement of an SVR, although further data are needed to determine the likely incremental impact of peginterferon plus ribavirin, late long-term effects of therapy, and the benefit of treatment in patients with advanced hepatic fibrosis.

Effect of HCV RNA suppression during peginterferon alfa-2a maintenance therapy on clinical outcomes in the HALT-C trial. Gastroenterology 2009; 137:1986-94. [PMID: 19747918 PMCID: PMC3774149 DOI: 10.1053/j.gastro.2009.08.067] [Citation(s) in RCA: 27] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/15/2009] [Revised: 08/07/2009] [Accepted: 08/31/2009] [Indexed: 01/14/2023]
Abstract
BACKGROUND & AIMS The Hepatitis C Antiviral Long-term Treatment Against Cirrhosis (HALT-C) trial demonstrated that low-dose peginterferon maintenance therapy was ineffective in preventing clinical outcomes in patients with chronic hepatitis C, advanced fibrosis, and failure to achieve a sustained virologic response during lead-in phase treatment with standard dose peginterferon/ribavirin. This analysis was performed to determine whether suppressing HCV RNA during the trial was associated with a reduction in clinical outcomes. METHODS Seven hundred sixty-four patients treated during the lead-in phase of HALT-C trial were randomized to either peginterferon alfa-2a (90 microg/week) maintenance therapy or no treatment (control) for 3.5 years. Clinical outcomes included an increase in Child-Turcotte-Pugh score, ascites, spontaneous bacterial peritonitis, hepatic encephalopathy, variceal hemorrhage, hepatocellular carcinoma, and mortality. RESULTS During the lead-in, >or=4-log(10) decline in serum HCV RNA occurred in 178 patients; 82% of whom lost detectable HCV RNA and later broke through or relapsed. These patients had significantly (P = .003) fewer clinical outcomes whether randomized to maintenance therapy or control. Following randomization, serum HCV RNA increased significantly in all 90 control patients and in 58 of 88 receiving maintenance therapy. Only 30 patients had persistent suppression of HCV RNA by >or=4 log(10) during maintenance therapy. No significant reduction in clinical outcomes was observed in these patients. CONCLUSIONS Viral suppression by >or=4 log(10) with full-dose peginterferon/ribavirin is associated with a significant reduction in clinical outcomes. Continuing low-dose peginterferon maintenance therapy, even in patients with persistent viral suppression, does not lead to a further decline in clinical outcomes.

Abstract
The aim of this study was to assess the association between liver stiffness measured by transient elastography (FibroScan) and the efficacy of pegylated interferon alpha-2b plus ribavirin combination treatment for patients with chronic hepatitis C virus (HCV) infection. We prospectively studied 145 Japanese patients with chronic HCV infection. FibroScan was done at baseline, at the end of treatment, and at 48 and 96 weeks after the end of treatment. The FibroScan values were significantly decreased for sustained virological response (SVR) patients (the mean rate of change; -16.2%, -32.2% and -43.5%) in comparison with non-SVR patients (-7.2%, -2.1% and +17.3%) at the end of treatment (P=0.0127), and 48 weeks (P<0.0001) and 96 weeks (P<0.0001) after the end of treatment. Among the non-SVR patients, the FibroScan values were significantly decreased for patients with biochemical response (BR) (-17.9%, -30.0% and -27.1%) in comparison with non-BR (-4.1%, +6.4% and +30.6%) at the end of treatment (P=0.0270), and 48 weeks (P<0.0001) and 96 weeks (P<0.0001) after the end of treatment. The FibroScan values may predict a progressively better clinical outcome for patients with successful virological and biochemical responses.

Abstract
BACKGROUND Hepatic fibrosis occurs in response to chronic liver injury, regardless of the cause. An impressive amount of knowledge concerning the pathogenesis and treatment of liver fibrosis has emerged over the past few years. The hallmark of this event is the activation of the hepatic stellate cell. The latter event causes accumulation of extracellular matrix and formation of scar, leading to deterioration in hepatic function. AIM To assess chronic liver injury, many invasive and non-invasive methods have been suggested. METHODS Although transient elastography, image analysis of fractal geometry and fibrotest with actitest have been used in clinical practice, liver biopsy remains the recommended choice, especially when histological staging of fibrosis or response to treatment is needed. CONCLUSIONS The recent advances in anti-viral therapy have resulted in many reports on fibrosis and even on cirrhosis regression, especially early and in young people. A number of new agents have been suggested for the treatment of fibrosis, with promising results in animals; however, their efficacy in humans remains to be elucidated. The investigation of heterogeneity and plasticity of hepatic stellate cells is a topic of scientific interest and may result in improvements in patient management.
