Abstract
BACKGROUND The chronic kidney disease (CKD) population, including kidney transplant recipients (KTRs) and subjects on renal replacement therapy, is particularly vulnerable to unfavorable outcomes from chronic hepatitis C (CHC). Currently, there are oral direct-acting antiviral agents (DAAs) available to eradicate the virus with favorable short-term outcomes; however, their long-term effects are lacking. The aim of the study is to assess the long-term efficacy and safety of DAA therapy in the CKD population. METHODS An observational, cohort single-center study was performed. Fifty-nine CHC subjects with CKD, treated with DAAs between 2016 and 2018, were enrolled in the study. Safety and efficacy profiles were assessed, including sustained virologic response (SVR), occult hepatitis C infection (OCI) incidence, and liver fibrosis. RESULTS SVR was achieved in 96% of cases (n = 57). OCI was diagnosed only in one subject following SVR. Significant liver stiffness regression was observed 4 years after SVR compared to baseline values (Mdn = 6.1 kPa, IQR = 3.75 kPa; 4.9 kPa, IQR = 2.9 kPa), p < 0.001. The most common adverse events were anemia, weakness, and urinary tract infection. CONCLUSION DAAs provide a safe and effective cure for CHC in both CKD patients and KTRs with a favorable safety profile in the long-term follow-up.

Occult hepatitis C infection identified in injection drug users with direct antiviral agents therapy and spontaneous resolution of hepatitis C virus infection. Virus Res 2023; 329:199104. [PMID: 37003528 DOI: 10.1016/j.virusres.2023.199104] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2022] [Revised: 03/23/2023] [Accepted: 03/24/2023] [Indexed: 04/03/2023]
Abstract
BACKGROUND Occult hepatitis C infection (OCI) is characterized by the detection of hepatitis C virus (HCV) RNA in hepatocytes and in peripheral blood mononuclear cells (PBMCs) without detection in serum. We aimed to evaluate OCI in drug and no drug users who achieved sustained virological response (SVR) after therapy with direct-acting antivirals (DAAs) and with HCV spontaneous resolution. METHODS Twenty-four patients in the AVP group (who achieved a SVR after DAAs therapy), 13 in the NAVP group (with HCV spontaneous resolution) and 7 HCV-RNA positive patients (CPP, control positive group) were included in the study. HCV/OCI-RNA was screened in serum and PBMCs samples of the patients by ddPCR for OCI patients' identification. Plasma and red blood cells (RBCs) samples of the patients were also evaluated for HCV/OCI-RNA detection by ddPCR. RESULTS OCI was presented in injection drug users (IDUs) in the AVP (20.8%) and NAVP (23.1%) groups by ddPCR with a higher statistically significant percentage detected in RBCs samples of the patients in the AVP group comparatively to NAVP (p<0.01) and CPP (p < 0.05) groups. CONCLUSION OCI was identified in IDUs patients of the AVP and NAVP groups by ddPCR. These results suggest that OCI patients in the AVP group might not be entirely cured, and that OCI patients in the NAVP group were not identified at clinical evaluation time when just serum samples were analysed. A higher percentage of HCV/OCI-RNA was detected in RBCs samples. Overall results recommends that HCV/OCI identification in patients with DAAs therapy and spontaneous resolution of HCV infection should be studied more accurately in future and in larger patient groups if possible. Additionally, suggest also PBMCs and RBCs samples as predictors for HCV/OCI diagnosis and management.

Durability of sustained virological response to glecaprevir/pibrentasvir and resistance development: A long-term follow-up study. Liver Int 2022; 42:1278-1286. [PMID: 35220658 DOI: 10.1111/liv.15211] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/20/2021] [Revised: 01/14/2022] [Accepted: 02/16/2022] [Indexed: 02/13/2023]
Abstract
BACKGROUND AND AIMS This study aimed to determine durability of sustained virologic response (SVR) in hepatitis C virus-infected participants treated with glecaprevir- and/or pibrentasvir-containing regimens. METHODS M13-576, a rollover study, evaluated the durability of SVR in a follow-up period of approximately 3 years after hepatitis C virus genotype 1-6-infected participants received a glecaprevir- and/or pibrentasvir-containing regimen in previous phase 2/3 clinical trials. The primary efficacy endpoint was the percentage of participants maintaining SVR and the percentage of participants experiencing relapse or reinfections. Resistance-associated substitutions and safety outcomes related to liver progression were also assessed. RESULTS Of 384 participants enroled, 377 participants were included in the as-observed population and 287 participants completed the study. In prior studies, 99.7% (376/377) of participants achieved SVR12; of those, an observed 99.5% (374/376) and 100% (286/286) completing the study, maintained SVR. After non-responder imputation of missing data, 286/376 participants (76%) maintained SVR. The participant previously not achieving SVR was a treatment-experienced male with compensated cirrhosis who had NS3 and NS5A substitutions at enrolment, which remained detectable for 12 months. Of the two participants not maintaining SVR, one was re-infected and one experienced late relapse at post-treatment week 60. Five participants (all with a fibrosis stage ≥F3) had hepatocellular carcinoma. No events were deemed related to glecaprevir/pibrentasvir. CONCLUSIONS Glecaprevir/pibrentasvir demonstrated long-term durability of efficacy after SVR12 was achieved. Hepatic-related decompensation events were not seen. Owing to low incidence of virologic failure, conclusions were not drawn on persistence of resistance-associated substitutions.

Abstract
The sustained virologic response and elimination of HCV is widely viewed as a true cure of chronic hepatitis C as it associates with amelioration of histological liver damage and improved clinical outcomes. Therefore, the existence and clinical burden of occult HCV infection (OCI) has been a controversial issue for many years. In this review, we summarize recently published data that adds new information on the molecular and clinical background of OCI and its epidemiological significance. We also identify and discuss the most important methodological pitfalls, which can be a source of inconsistency between studies. Data that have accumulated so far, strongly support the existence of extrahepatic HCV replication in individuals negative for serum HCV-RNA by conventional clinical tests. OCI emerges as a condition where the immune system is unable to fully resolve infection but it is continuously stimulated by low levels of HCV antigens, leading to progression of liver pathology and extrahepatic HCV-related complications. Moreover, the development of monitoring strategies or management guidelines for OCI is still hampered by the lack of clear definition and the confusion regarding its clinical significance. Careful study design and the introduction of uniform protocols for the detection of low-level HCV-RNA are crucial for obtaining reliable data on OCI.

Abstract
Sustained virologic response at posttreatment Week 12 (SVR12) is the widely accepted efficacy endpoint for direct-acting antiviral agents. Those with hepatitis C virus (HCV) are presenting younger with milder liver disease, potentially reducing need for long-term liver posttreatment monitoring. This analysis aimed to determine the positive predictive value (PPV) of SVR at posttreatment Week 4 (SVR4) for achieving SVR12 in patients with HCV, without cirrhosis or with compensated cirrhosis, receiving glecaprevir/pibrentasvir (G/P) in clinical trials. An integrated dataset from 20 Phase 2 and 3 clinical trials of G/P was evaluated in patients with 8-, 12- or 16-week treatment duration consistent with the current label (label-consistent group), and in all patients regardless of treatment duration consistency with the current label (overall group). Sensitivity analyses handled missing data either by backward imputation or were excluded. SVR4 PPV, negative predictive value (NPV), sensitivity and specificity were calculated for achieving SVR12 in both groups, and by treatment duration in the label-consistent group. SVR was defined as HCV ribonucleic acid 99% in both groups regardless of treatment duration. Not achieving SVR4 had 100% NPV and sensitivity for all groups. SVR4 measure had 79.5% specificity for identifying patients who did not achieve SVR12. Across 20 Phase 2/3 clinical trials of G/P, SVR4 was highly predictive of SVR12. Long-term follow-up to confirm SVR may not be necessary for certain populations of patients with HCV.

Abstract
Epidemiological data clearly indicate a link between hepatitis C virus (HCV) and altered glucose homeostasis. Objective: To evaluate the response of treatment with direct antiviral agents (DAAs) on metabolic variables of patients with hepatitis C. Methods: Observational, cross-sectional study in a sample of patients with hepatitis C starting therapy with DAAs followed on the hepatology division of Federal University of Rio de Janeiro State. Data were collected in two stages: before the start of therapy and between 12 and 52 weeks after obtaining the sustained virological response. Results: In the baseline assessment of the 97 patients selected, 19.3% were obese, 38.6% were overweight, 50% were hypertensive, 43.8% were pre-diabetic, 12.5% were diabetic, 31.2% were dyslipidemic, and 21.8% had metabolic syndrome. There was an increase in total cholesterol and LDL levels (p < 0.001), and a non-significant reduction in blood glucose, glycated hemoglobin, insulin, and HOMA-IR levels after treatment. In the post-treatment, there was a reduction in fibrosis (p = 0.016), with a reduction in the levels of GGT, AST, and ALT (all with p < 0.001), as well as in the FIB4 and APRI scores (both with p < 0.001) and in the degree of fibrosis evaluated by elastography represented in kPa (p = 0.006). The blood glucose level was higher in patients with steatosis (p = 0.039) after treatment. There was a positive pre-treatment correlation between the degree of fibrosis (kPa) and FIB4 (r = 0.319, p = 0.004), APRI (r = 0.287, p = 0.010), and the NAFLD score (r = 0.275, p = 0.016). Conclusion: Patients with hepatitis C had a high prevalence of metabolic disturbance in the pre-treatment phase, but the therapy did not show beneficial effects, especially on glucose metabolism.

Hepatitis C viral RNA in blood mononuclear cells of patients treated with directly acting antivirals. Arab J Gastroenterol 2021; 22:158-163.

Abstract
BACKGROUND AND STUDY AIMS Occult hepatitis C viral infection (OCI) may have serious complications, such as relapse, ongoing histological impairment, hepatic decompensation, hepatocellular carcinoma, and the possible risk of transmission. This study was conducted to assess the occurrence and prevalence of secondary OCI in patients with chronic hepatitis C viral infection (HCV) who received a complete course of directly acting antivirals (DAAs). PATIENTS AND METHODS Antiviral therapy consisted of sofosbuvir + daclatasvir ± ribavirin for 12 weeks to 90 treatment-naive, compensated, chronic HCV patients. Plasma and peripheral blood mononuclear cells (PBMCs) were tested for HCV RNA viral load by quantitative, reverse transcription, real-time PCR at 8, 12 (Group I, n = 45), and 24 (Group II, n = 45) weeks after treatment initiation. RESULTS By week 8, only 2 and 7 patients were positive for HCV RNA in plasma and PBMCs, respectively. No HCV RNA was detected by weeks 12 or 24 in the PBMCs of Groups I and II, respectively. Older age was significantly associated with HCV RNA positivity in plasma and PBMCs (n = 8) at week 8 compared with HCV RNA negativity (n = 82). No other significant differences were observed for any other variables. CONCLUSION The development of secondary OCI among easy-to-treat patients following a full course of DAA treatment doesn't exist, hence, we do not recommend testing the HCV RNA in the PBMCs after complete course of treatment in this patient category. The detection of HCV RNA in PBMCs is recommended as a confirmatory test of cure following a shortened DAA treatment regimen.

Abstract
BACKGROUND AND AIM Patients with chronic hepatitis C (CHC) treated with direct-acting antivirals (DAAs) are still at risk for developing hepatocellular carcinoma (HCC) even after achieving sustained virologic response (SVR). Liver-stiffness measurement (LSM) on imaging has been investigated as a predictor of HCC occurrence. OBJECTIVES To provide systematic summary of the predictive value of LSM in predicting HCC occurrence in HCV patients treated with DAA. METHODS A comprehensive literature search of the PubMed-MEDLINE and EMBASE databases was performed to identify studies that evaluated the predictive value of LSM in CHC patients treated with DAAs. Pooled hazard ratio (HR) comparing HCC occurrence between patients with positive and negative results on LSM was calculated for all studies and various subgroups. Subgroup analyses and meta-regression were performed. RESULTS A review of 135 candidate articles identified eight eligible articles with a total of 3398patients for qualitative review and meta-analysis. The pooled HR for HCC occurrence determined by LSM was 3.43 (95% confidence interval [CI], 1.63-7.19) with heterogeneity (I2 = 81.87%, P < 0.001), thus indicating that LSM might be helpful for predicting HCC occurrence. In subgroup analyses, pooled HRs were different according to the study design (2.29; [95% CI, 0.96-5.45] for retrospective studies; 4.61 [95% CI, 2.44-8.71] for prospective studies), study population (4.00 [95% CI, 2.00-7.99] for CHC; 2.64 [0.99-7.00] for CHC with liver cirrhosis) and LSM parameter (3.17 [95% CI, 1.35-7.41] for baseline LSM; 4.19 [95% CI, 1.89-9.29] for others). In multivariate meta-regression, study design was the only influencing factor for pooled HR for HCC occurrence (P < 0.05). CONCLUSIONS Consistent evidence demonstrated the predictive value of LSM for HCC occurrence in CHC patients treated with DAA. The significant influencing factor for risk of HCC occurrence indicated by LSM was study design.

Abstract
Abstract
Background
Viral hepatitis is the seventh leading cause of mortality globally, and half of this mortality is attributed to hepatitis C virus (HCV). Egypt has the highest HCV prevalence worldwide, with an estimated 14.7% of the population being HCV-positive. HCV infection is the primary cause of liver fibrosis, cirrhosis, and hepatocellular carcinoma. Liver fibrosis varies in severity during chronic HCV infection, and 10–20% of chronic hepatitis C (CHC) patients with severe fibrosis develop cirrhosis. The goal of this work was to assess the clinico-demographic predictors of severity of HCV-induced fibrosis in a cohort of Egyptian patients.
Results
A cohort of Egyptian patients with chronic HCV genotype 4a infection showed significant association between severe fibrosis stages and obesity, represented by a higher body mass index (BMI), low albumin level, high alpha-fetoprotein (AFP) level, low thyroid-stimulating hormone (TSH) level, and high alkaline phosphatase (ALP) level. Multivariate analysis delineated BMI, TSH, and ALP as independent significant variables that could predict the risk of fibrosis severity in HCV infections.
Conclusion
This study argues in favor of using the biomarker profile of CHC patients infected with HCV genotype 4a to identify patients at higher risk of developing severe fibrosis, which is a necessary first step towards precision medicine via patient stratification.

Abstract
The objectives of this study were to estimate the prevalence of concurrent alcohol and substance use among patients living with HIV/HCV co-infection and to compare demographic and clinical characteristics of those with concurrent alcohol and substance to those with alcohol or substance use, and to those who were abstinent. We conducted an analysis of patient reported outcomes data of patients living with HIV/HCV co-infection (n = 327) who transitioned from primary care to sub-specialty care for evaluation of candidacy for HCV treatment at a university-affiliated HIV Clinic. The prevalence of self-reported concurrent alcohol and substance use was 33%. A higher proportion of those with concurrent alcohol and substance use were currently smoking tobacco, and those who were abstinent had higher ratings of health-related quality of life compared to those with alcohol or substance use. To reduce patients' risk for progression to advanced stages of HIV, HCV, and liver-related disease due to continued alcohol and substance and tobacco use, social workers and other health care professionals are encouraged to develop and implement intervention strategies to assist patients living with HIV/HCV co-infection in efforts to achieve behavioral change.

Abstract
Several studies have reported the persistence of HCV RNA in liver and/or peripheral blood mononuclear cells (PBMCs) in spite of undetectable viremia in patients who have achieved sustained virological response (SVR). This event, defined as occult HCV infection, remains controversial and low titers of persistent virus may be underestimated because it has not yet been analyzed by a highly sensitive test such as droplet digital PCR (ddPCR). This method provides an alternate ultra-sensitive detection technique for very low numbers of copies of viral RNA or DNA. The aim of this study was to evaluate the persistence of HCV in HIV-coinfected patients with long-term SVR using ddPCR. For each patient, the presence of HCV RNA in serum and PBMCs at baseline was determined by nested RT-ddPCR. Patients with HCV RNA in PBMCs at baseline were followed until the end of the study. One hundred and twenty-three patients were analyzed for persistence of HCV RNA in serum and PBMCs. Persistence of HCV was not found in serum in any patient. HCV RNA was detected in PBMCs in one patient (0.81%; 95% CI: 0.04–3.94) and resolved spontaneously during follow-up. Persistence of HCV RNA in PBMCs is not a common event in HIV/HCV co-infected patients with long-term SVR evaluated by RT-ddPCR.

No evidence of occult hepatitis C or E virus infections in liver-transplant patients with sustained virological response after therapy with direct acting agents. Transpl Infect Dis 2019; 21:e13093. [PMID: 30972874 DOI: 10.1111/tid.13093] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2018] [Revised: 02/21/2019] [Accepted: 04/07/2019] [Indexed: 12/17/2022]
Abstract
BACKGROUND AND AIMS It has been recently suggested that occult hepatitis C virus (HCV) infection and hepatitis E virus (HEV) reactivation might occur after direct acting antiviral agent-induced (DAA-induced) sustained virological response (SVR). The aim of our study was to identify occult HCV and HEV infection in a cohort of organ transplant patients who had achieved SVR and had persistent elevation in liver-enzyme levels. PATIENTS AND METHOD Sixty-six liver and/or kidney transplant patients were treated with DAAs. All but one achieved SVR12. Twenty-nine (8-39) months post-SVR12, 8 of the 65 patients (12.3%) who achieved SVR12 had persistently elevated liver enzyme levels. In 1 patient, this was related to hepatitis B virus reactivation. In the 7 remaining patients, blood samples (n = 7), liver biopsies (n = 4), and peripheral blood mononuclear cells (PBMCs) (n = 7) were collected simultaneously in order to identify occult HCV or HEV infection. RESULTS Hepatitis C virus RNA and HEV RNA were not detected in serum, liver tissues, or PBMCs. No HEV reactivation was observed after HCV clearance in patients who had anti-HEV IgG. CONCLUSION Our study suggests that there is no occult HCV or HEV infection in transplant patients after successful treatment of HCV infection with DAAs, even in patients with a persistent elevation of liver enzyme levels. However, due to the small number of patients included in our study, this finding should be confirmed in a larger cohort.

Hanafy AS, Soliman S, Abd-Elsalam S. Rescue therapy for chronic hepatitis C virus infection after repeated treatment failures: Impact on disease progression and risk of hepatocellular carcinoma. Hepatol Res 2019; 49:377-384. [PMID: 30570817 DOI: 10.1111/hepr.13303] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/09/2018] [Revised: 12/11/2018] [Accepted: 12/17/2018] [Indexed: 12/14/2022]
Abstract
AIM Retreatment after previous failure of direct-acting antivirals for hepatitis C virus (HCV) infection is a challenging decision. The importance of achieving viral eradication on modification of disease progression and outcome, including the risk of hepatocellular carcinoma (HCC), remains a critical issue to be evaluated. METHODS One hundred patients with repeated failure of sofosbuvir and ribavirin or triple therapy with sofosbuvir, ribavirin, and daclatasvir were divided into a study group (n = 50) given rescue therapy (sofosbuvir, daclatasvir, simeprevir, and ribavirin) or a control group (n = 50) matched for age, sex, and pretreatment variables (Child-Turcotte-Pugh score and Fibrosis-4 score). Follow-up was undertaken after the last non-response to detect serious adverse events, such as hepatic decompensation and development of HCC. RESULTS The study group achieved sustained virologic response (SVR) in 47 of 50 (94%) patients. The control group had significantly higher HCC rates than the study group (7 vs. 1 patients), with an odds ratio of 5.44. The rescue therapy was associated with significantly longer time to the occurrence of adverse events. Repeated treatment failures were associated with progression of FibroScan values in the control group (21 ± 4.5 vs. 10 ± 1.5 kPa, P = 0.001); achieving SVR in the study group stopped fibrosis progression despite non-significant increase from baseline (13.2 ± 3.2 vs. 10.6 ± 0.6, P = 0.12). CONCLUSIONS Rescue treatment for HCV infection was highly effective in achieving SVR, less expensive than the newer agents, and is associated with diminished risk of serious adverse events, mainly HCC in these patients.
