Impact of safety-related dose reductions or discontinuations on sustained virologic response in HCV-infected patients: Results from the GUARD-C Cohort
BACKGROUND:
Despite the introduction of direct-acting antiviral agents for chronic hepatitis C virus (HCV) infection, peginterferon alfa/ribavirin remains relevant in many resource-constrained settings. The non-randomized GUARD-C cohort investigated baseline predictors of safety-related dose reductions or discontinuations (sr-RD) and their impact on sustained virologic response (SVR) in patients receiving peginterferon alfa/ribavirin in routine practice.
METHODS:
A total of 3181 HCV-mono-infected treatment-naive patients were assigned to 24 or 48 weeks of peginterferon alfa/ribavirin by their physician. Patients were categorized by time-to-first sr-RD (Week 4/12). Detailed analyses of the impact of sr-RD on SVR24 (HCV RNA <50 IU/mL) were conducted in 951 Caucasian, noncirrhotic genotype (G)1 patients assigned to peginterferon alfa-2a/ribavirin for 48 weeks. The probability of SVR24 was identified by a baseline scoring system (range: 0-9 points) on which scores of 5 to 9 and <5 represent high and low probability of SVR24, respectively.
RESULTS:
SVR24 rates were 46.1% (754/1634), 77.1% (279/362), 68.0% (514/756), and 51.3% (203/396), respectively, in G1, 2, 3, and 4 patients. Overall, 16.9% and 21.8% patients experienced 651 sr-RD for peginterferon alfa and ribavirin, respectively. Among Caucasian noncirrhotic G1 patients: female sex, lower body mass index, pre-existing cardiovascular/pulmonary disease, and low hematological indices were prognostic factors of sr-RD; SVR24 was lower in patients with 651 vs. no sr-RD by Week 4 (37.9% vs. 54.4%; P = 0.0046) and Week 12 (41.7% vs. 55.3%; P = 0.0016); sr-RD by Week 4/12 significantly reduced SVR24 in patients with scores <5 but not 655.
CONCLUSIONS:
In conclusion, sr-RD to peginterferon alfa-2a/ribavirin significantly impacts on SVR24 rates in treatment-naive G1 noncirrhotic Caucasian patients. Baseline characteristics can help select patients with a high probability of SVR24 and a low probability of sr-RD with peginterferon alfa-2a/ribavirin
Incidence of HCC recurrence after DAA treatment for HCV in a multicentre Italian cohort study
AbstractBackground and aimThe present realâlife multicentre, prospective study aims to investigate the effects of directâacting antivirals (DAAs) in HCV patients with a previous successfully treated hepatocellular carcinoma (HCC), in terms of neoplastic recurrence and sustained virological response (SVR) rates.MethodsFrom March 2015 to March 2017, all consecutive HCV patients with a previous successfully treated HCC who underwent DAA therapy were enrolled. Neoplastic recurrence was used as the primary outcome, whereas the secondary outcomes were patient characteristics predicting HCC recurrence. Cumulative probabilities of recurrence were extracted from timeâtoâevent curves based on the KaplanâMeier method. Hazard ratios with 95% confidence intervals were estimated using univariate and multivariate Cox regressions.ResultsA total of 101 patients were enrolled: 83% of them were in ChildâPugh class A, 88% had a history of HCC BCLC stage 0/A and 91.1% achieved SVR. The median time from the last successful HCC treatment to DAA start was 10.1 months [IQR: 5.6â16.7]. Thirtyâone HCC recurrences were observed from DAA start (median followâup: 31.7 months). The incidence rate of recurrence was 20.5/100 personâyears. The 6â, 12â and 24âmonths HCC recurrence rates from the last HCC treatment were 1%, 8.9% and 25.6% respectively. DAA treatment failure, higher level of total bilirubin, higher BMI and higher level of AFP were significantly associated with higher risk of HCC recurrence in both univariate and Cox multivariate analysis.ConclusionsOur data suggest that the achievement of SVR and the absence of wellâknown HCC risk factors reduce recurrence in patients who have taken DAAs
Reproducibility of shear wave elastography (SWE) in patients with chronic liver disease
The presence of significant fibrosis is an indicator for liver disease staging and prognosis. The aim of the study was to determine reproducibility of real-time shear wave elastography using a hepatic biopsy as the reference standard to identify patients with chronic liver disease. Forty patients with chronic liver disease and 12 normal subjects received shear wave elastography performed by skilled operators. Interoperator reproducibility was studied in 29 patients. Fibrosis was evaluated using the Metavir score. The median and range shear wave elastography values in chronic liver disease subjects were 6.15 kPa and 3.14-16.7 kPa and were 4.49 kPa and 2.92-7.32 kPa in normal subjects, respectively. With respect to fibrosis detected by liver biopsy, shear wave elastography did not change significantly between F0 and F1 (p = 0.334), F1 and F2 (p = 0.611), or F3 and F4 (0.327); a significant difference was observed between the F0-F2 and F3-F4 groups (p = 0.002). SWE also correlated with inflammatory activity (Rs = 0.443, p = 0.0023) and ALT levels (Rs = 0.287, p = 0.0804). Age, sex and body mass index did not affect shear wave elastography measurements. Using receiver operator characteristic curves, two threshold values for shear wave elastography were identified: 5.62 kPa for patients with fibrosis (â„F2; sensitivity 80%, specificity 69.4%, and accuracy 77%) and 7.04 kPa for patients with severe fibrosis (â„F3; sensitivity 88.9%, specificity 81%, and accuracy 89%). Overall interobserver agreement was excellent and was analysed using an interclass correlation coefficient (0.94; CI 0.87-0.97).This study shows that shear wave elastography executed by skilled operators can be performed on almost all chronic liver disease patients with high reproducibility. It is not influenced by age, sex or body mass index, identifies severely fibrotic patients and is also related to inflammatory activity

Screening, Linkage to Care and Treatment of Hepatitis C Infection in Primary Care Setting in the South of Italy
Hepatitis C virus (HCV) infection remains a pressing public health issue. Our aim is to assess the linkage to care of patients with HCV diagnosis and to support the proactive case-finding of new HCV-infected patients in an Italian primary care setting. This was a retrospective cohort study of 44 general practitioners (GPs) who managed 63,955 inhabitants in the Campania region. Adults with already known HCV diagnosis or those with HCV high-risk profile at June 2019 were identified and reviewed by GPs to identify newly diagnosed of HCV and to assess the linkage to care and treatment for the HCV patients. Overall, 698 HCV patients were identified, 596 with already known HCV diagnosis and 102 identified by testing the high-risk group (2614 subjects). The 38.8% were already treated with direct-acting antivirals, 18.9% were referred to the specialist center and 42.3% were not sent to specialist care for treatment. Similar proportions were found for patients with an already known HCV diagnosis and those newly diagnosed. Given that the HCV infection is often silent, case-finding needs to be proactive and based on risk information. Our findings suggested that there needs to be greater outreach, awareness and education among GPs in order to enhance HCV testing, linkage to care and treatment
Impact of telaprevir in HCV patients with cirrhosis and RVR: Real-life data from boceprevir or telaprevir based âtriple therapyâ experience in southern Italy
Background and Rationale of Study: The real-life data of triple therapy-based treatment in patients with chronic hepatitis C were investigated in this survey of 12 clinical centers of southern Italy. This retrospective study analyzed data from 176 consecutive patients. Methods: 125 (70%) patients were treated with telaprevir, and 51(30%) with boceprevir. There were no differences in demographic characteristics between the groups. The degree of Liver Fibrosis (LF) was evaluated according to Liver Biopsy (LB) and/or Transient Elastography (TE). 53/176 patients (30%) had liver cirrhosis. Sixteen patients (9%) were treatment naĂŻve, and the remaining were not: 92 were non-responders (52, 84%), 63 relapsed (35,79%), and 5 discontinued treatment (2, 8%). Results: Overall, the rapid Virological Response (RVR) rate was 67.6%. Of the 103 patients who had follow-up for at least 12 weeks after the end of treatment, 61 (59, 2%) achieved a Sustained Virological Response (SVR). According to multivariate analysis for SVR, RVR was the only independent predictive factor of SVR, irrespective of the degree of LF and the type of response to previous treatments. In telaprevir-treated patients, the rate of RVR was similar in patients with F0-F2, F3 and F4 fibrosis (85%, 84%, 78%, respectively), and the SVR rates among RVR patients was similar irrespective of LF. Conclusions: Data from this real-life study confirm the efficacy reported in clinical trials, although cirrhosis appears to play a smaller role in influencing treatment efficacy. Moreover, RVR is the only independent predictive factor of response regardless of cirrhosis. Based on RVR and for patients with cirrhosis, a shorter therapy might be considered, at least with telaprevir-based therapy
