De Santis A, Maggi D, Lubrano Lobianco F. Safety and efficacy of directly-acting antiviral therapy for chronic hepatitis C virus in elderly people. Aging Med (Milton) 2021; 4:304-316.

Abstract
INTRODUCTION In Italy, the prevalence of hepatitis C virus (HCV) infection is higher in the elderly, although the efficacy and safety of treatment in this population has not been extensively studied. Moreover, little is known about how much pharmacological interaction affects eligibility to treatment and to what extent the treatment affects subsequent outcomes. METHODS We retrospectively analyzed the efficacy and safety of directly acting antivirals (DAAs), drug-to-drug interactions, and post-treatment outcomes in 138 patients with HCV aged 70 years or older, who were consecutively treated in our center between 2015 and 2020. RESULTS The mean age was 77 years old (range = 70-95 years old). The Cumulative Illness Rating Scale of pretherapy severity was classified as moderate to severe in 65% of patients. Fifty-five patients (40%) presented compensated cirrhosis, eight of which were complicated by hepatocellular carcinoma (HCC) and all were cured before treatment. One hundred two patients (74%) were taking two or more drugs (range = 0-5 concomitant drugs registered) and in 29 patients (21%) we found potential drug-to-drug interaction. In 11 of those 29 patients (38%), we were forced to change the chronic therapy, when all therapeutic regimens were equal in terms of efficacy and interactions, to avoid potentially serious drug interactions. One serious adverse event occurred in our sample population (i.e., diverticular bleeding due to interaction with direct oral anticoagulants [DOACs]), whereas mild side effects occurred in 37% of patients. The undetectability of HCV RNA at the end of treatment was achieved in 97% of patients, whereas a sustained virological response (SVR) 12 and SVR 24 were obtained in 98% of patients. When comparing pretherapy with post-therapy data, after a medium follow-up of 15 months (median = 1 year, minimum = 2 months, and maximum = 4 years), we observed a reduction in the incidence of episodes of liver decompensation in patients with cirrhosis and a slight increase in the incidence of HCC (with 6 recurrent and 5 de novo HCC), diagnosed within 13 months from the end of therapy. In all patients, we found a significant improvement in all ultrasound variables and a significant reduction in the elastographic measurements. No significant differences in outcomes were observed dividing the population into patients aged ≥ 80 and < 80 years old. CONCLUSIONS Directly acting antiviral therapy was found to be safe and effective in elderly people, and, despite the large number of concomitant drugs, pharmacological interactions appeared to not affect the adherence to therapy or the incidence of adverse events. Side effects were mostly independent from the type of DAA used and from the burden of comorbidity. In long-term follow-up, the benefit of DAA therapy mainly concerned liver pathology and should be strongly advised in patients with cirrhosis. The therapy was found to not affect extrahepatic comorbidities but allowed to end follow-up in noncirrhotic patients with savings in terms of resources. Finally, patients should not be excluded based on age if they have a good performance status.

Abstract
Background: Treatment of chronic Hepatitis C with directly acting antivirals (DAAs) can bring to sustained virologic response (SVR) in approximately 95% of patients. Efficacy and safety of DAAs in aging patients has not been widely analyzed. We aimed to determine safety and efficacy of DAA-based regimens in a cohort of elderly patients in a real-life setting.Research Design and Methods: We retrospectively investigated safety and efficacy of DAAs in HCV patients of 80 years or older treated in three Hepatology Units.Results and Expert opinion: During the study period, 170 patients older than 80 years received DAAs. Their mean age was 82,3 years. The predominant HCV genotype was 1 (100 patients, 59%). Among the 93 cirrhotic patients (54,7%), 18 had CPT score > A5. Different DAAs regimens were used. Concomitant drugs were common: 163 patients (95,8%) taking at least one drug. In 11 patients, usual therapy had to be changed to start antiviral treatment. Two serious adverse events occurred. Four patients terminated treatment prematurely. In total, 45 patients (26,5%) testified mild side effects. HCV-RNA undetectability at week 12 of treatment follow-up was achieved in 168/170 patients. DAA treatment in HCV patients of 80 years or older is efficacious and safe. Drug-drug interaction should be judiciously evaluated before starting therapy.

J Am Geriatr Soc 2019; 68:379-387. [PMID: 31647119 DOI: 10.1111/jgs.16206] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2019] [Revised: 09/04/2019] [Accepted: 09/08/2019] [Indexed: 12/25/2022]
Abstract
OBJECTIVES Data on the virologic response and tolerability of direct-acting antivirals (DAAs) are lacking in older people because these individuals are underrepresented in clinical trials. This study aimed to assess the effectiveness and tolerability of DAA regimens in older individuals in a large cohort of real-life clinical practice. METHODS In this retrospective study, patients with chronic hepatitis C infection between 2017 and 2018 were divided into patients aged 65 years and older and those younger than 65 years. We evaluated the sustained virologic response rates (SVRs) in both groups. Further subgroup analyses on the SVRs for patients aged 65 to 74, 75 to 84, and 85 years and older were performed. We also analyzed the predictors of treatment response in older individuals. RESULTS Among 1151 eligible patients, 516 were in the older group and 635 were in the younger group. The overall treatment response in the entire cohort was 97.7%. A significantly higher percentage of patients presented with advanced stages of fibrosis in the older group (53.1% vs 39.5%; P = <.001). The SVR rates were similar between the two groups (98.3% vs 97.7%; P = .18). In multivariate models, age was not predictive of SVR after adjusting for confounders. Subgroup analyses in the age groups of 65 to 74, 75 to 84, and older than 85 years showed similar treatment response rates (97.4%, 97.2%, and 86.7, respectively; P = .06) and advanced fibrosis (50.8%, 61.5%, and 53.3%, respectively; P = .14). CONCLUSION Although older people exhibit a significantly higher frequency of fibrosis, DAAs produce high rates of SVR in all age groups, and the age of the patient does not seem to have a significant impact on the efficacy of DAAs including patients in the oldest age category (≥75 y). Treatment should not be withheld in older individuals. J Am Geriatr Soc 68:379-387, 2020.

Abstract
Background Interferon therapy is used as a line of treatment of chronic hepatitis C virus (HCV) in several areas of the world including Egypt. Objective Our aim was to investigate the value of hepatic progenitor cells (HPCs) in predicting response of patients with chronic HCV, genotype 4 to pegylated interferon (PEGIFN) plus ribavirin (RBV) therapy. Methods Pre-treatment liver biopsies obtained from 110 patients with chronic HCV, genotype 4 were examined immunohistochemically for HPCs using cytokeratin19. The mean number of HPCs as ductular reaction (DR) and as isolated progenitor cells (IPCs) was counted in each case. The patients were classified into: those with sustained virological response (SVR) and those who did not achieve SVR. The results were compared between the two groups. Also, the relationships between HPCs and other clinico-pathologic variables were estimated using multivariate analysis. Results The mean number of HPCs was the only independent predictor of therapeutic response, being significantly higher in non-responders (P = 0 for DR and P = 0.03 for IPCs). On the other hand, fibrosis stage and steatosis were the only independent factors which showed a significant direct association with the mean number of HPCs in the form of DR and IPCs (P = 0 for each). Conclusion The number of HPCs provides prognostic information in chronic HCV since it is significantly associated with stage of fibrosis. More importantly, it can be used as a marker to predict response of patients with chronic HCV to PEGIFN plus RBV therapy.

World J Gastroenterol 2017; 23:7899-7905. [PMID: 29209131 PMCID: PMC5703919 DOI: 10.3748/wjg.v23.i44.7899] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/11/2017] [Revised: 09/06/2017] [Accepted: 09/13/2017] [Indexed: 02/07/2023] Open
Abstract
AIM To prospectively evaluate the efficacy of sofobuvir (SOF) in hepatitis C patients infected with hepatitis C virus (HCV) genotype 3 in Pakistan.
METHODS The present study was performed with the coordination of gastroenterology and pathology departments of Shalamar Hospital Lahore from August 2014 to May 2016. The total number of patients included in this study was 1375 and all of them were infected with HCV genotype 3. On the basis of drug combinations, all the patients were separated into two groups. The first group of patients was treated for 24 wk with SOF (Sovaldi® by Gilead Sciences) plus ribavirin (RBV) [Ribazol® by Getz Pharma Pakistan (PVT) Ltd], while the patients of the second group were treated with SOF + RBV + pegylated-interferon (pegIFN) alfa-2a (Ropegra by Roach) for 12 wk. HCV genotyping and viral load measurement were performed on fully automated Abbott Real-Time PCR system (Abbott m24sp automated nucleic acid extraction system and Abbott m2000rt amplification system; abbott Molecular, Des Plaines, IL, United States). For the assessment of sustained virological response (SVR), all HCV RNA negative patients were followed for 12 weeks after the treatment completion. Any patient with less than 12 IU/mL viral load after 12 wk of treatment completion was considered as a sustained virological responder (SVR-12).
RESULTS A total of 1375 patients chronically infected with HCV genotype 3 were treated with two drug combinations SOF + RBV and SOF + RBV + pegIFN alfa-2a. On the basis of these drug combinations, patients were divided into two groups (first and second). Overall SVR-12 was excellent in both groups (99.17% and 97.91%). Older patients (> 40 years) of second group showed lower SVR-12 (93.46%) compared to first group older patients (98.79%), while in the younger patients of both groups, the SVR-12 rate was almost the same (99.54% in first group and 99.05% in second group). No such difference regarding SVR-12 rate was seen in males and females of first group patients (99.68% and 98.88%, respectively), while in second group the males were found to be better responders compared to females (98.96% and 95%). The SVR-12 rate in previously treated patients of first group was better (99.34%) than second group (93.70%), while naïve patients of second group were marginally better responders (99.25%) than first group (97.80%). Rapid viral response at week-4 was found to be a very effective predictor for assessing the SVR rate at this stage of therapy in both groups. Headache, anemia and fatigue were common side effects in both groups either treated with SOF + RBV or SOF + RBV + pegIFN alfa-2a, while the overall percentage of the side effects was higher in second group.
CONCLUSION The remarkable SVR response rate of HCV genotype 3 infected patients to SOF provided a new way to look forward to eliminate hepatitis C from our region.

Abstract
The availability of direct-acting antiviral agents (DAA) regimens has expanded the pool of patients eligible for treatment. However, data on the virologic response and tolerability of DAAs in elderly patients are lacking. We evaluated the efficacy and safety of DAAs in patients with advanced fibrosis/cirrhosis in real-life practice with the focus on those aged ≥65 years. Between January and December 2015, all consecutive patients with HCV-related advanced fibrosis/cirrhosis treated with DAA at eleven tertiary referral centres in Emilia Romagna (Italy) were enrolled. Regimen choice was based on viral genotype and stage of disease, according to guidelines. The primary end point was sustained virologic response 12 weeks after the end of treatment (SVR12). Overall, 282 of 556 (50.7%) patients evaluated were elderly, most of them with cirrhosis. Antiviral therapy was stopped prematurely in four (1.4%) patients. Two patients, both with cirrhosis, died during treatment due to worsening of liver/renal function. SVR12 was achieved by 94.7% and was comparable to that obtained in patients aged <65 (P=.074). Similar data were also reported in subgroup of patients aged ≥75 years. All patients with advanced fibrosis achieved virologic response. SVR12 was 80.8% in Child-Pugh-Turcotte (CTP)-B cirrhosis and 95.4% in CTP-A (P=.013). According to genotype, the SVR12 was achieved in 172 of 181 (95%) with genotype 1b cirrhosis and in 44 of 48 (91.7%) with genotype 2 cirrhosis. In conclusions, in a real-world setting, DAAs are safe and effective in elderly patients with HCV-related advanced fibrosis/cirrhosis, but SVR12 is lower with worsening CTP class.

Safety and efficacy of ledipasvir/sofosbuvir for the treatment of genotype 1 hepatitis C in subjects aged 65 years or older. Hepatology 2016; 63:1112-9. [PMID: 26704693 DOI: 10.1002/hep.28425] [Citation(s) in RCA: 63] [Impact Index Per Article: 7.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/05/2015] [Revised: 12/17/2015] [Accepted: 12/21/2015] [Indexed: 12/12/2022]
Abstract
UNLABELLED Elderly subjects have been historically underrepresented in clinical trials involving antiviral hepatitis C therapies. The aim of this analysis was to retrospectively evaluate the safety and efficacy of ledipasvir/sofosbuvir (LDV/SOF) by age groups of <65 years versus ≥65 years among subjects enrolled in phase 3 trials. Four open-label phase 3 clinical trials evaluated the safety and efficacy of LDV/SOF with or without ribavirin (RBV) for the treatment of genotype 1 chronic hepatitis C virus. Sustained virological response at 12 weeks, treatment-emergent adverse events (AEs), and graded laboratory abnormalities were analyzed according to age group. Of the 2293 subjects enrolled in four phase 3 trials, 264 (12%) were ≥65 years of age, of whom 24 were aged ≥75 years. Sustained virological response at 12 weeks was achieved by 97% (1965/2029) of subjects aged <65 years and 98% (258/264) of subjects aged ≥65 years. The most common AEs in both LDV/SOF groups that occurred in ≥10% of subjects were headache and fatigue. The rate of study discontinuation due to AEs was similar in the two age cohorts. The use of RBV in 1042 (45%) subjects increased the number of AEs, treatment-related AEs, and AEs leading to study drug modification/interruption, particularly among elderly subjects. CONCLUSIONS LDV/SOF with or without RBV was highly effective for treatment of genotype 1 chronic hepatitis C virusin subjects aged 65 and older. Addition of RBV did not increase sustained virological response at 12 weeks rates but led to higher rates of AEs, especially in elderly subjects.

Abstract
BACKGROUND Treatment with Peginterferon Alpha-2b plus Ribavirin is the current standard therapy for chronic hepatitis C (CHC). However, many host related and viral parameters are associated with different outcomes of combination therapy. OBJECTIVES The aim of this study was to develop an artificial neural network (ANN) model to predetermine individual responses to therapy based on patient's demographics and laboratory data. PATIENTS AND METHODS This case-control study was conducted in Tehran, Iran, on 139 patients divided into sustained virologic response (SVR) (n = 50), relapse (n = 50) and non-response (n = 39) groups according to their response to combination therapy for 48 weeks. The ANN was trained 300 times (epochs) using clinical data. To test the ANN performance, the part of data that was selected randomly and not used in training process was entered to the ANN and the outputs were compared with real data. RESULTS Hemoglobin (P < 0.001), cholesterol (P = 0.001) and IL-28b genotype (P = 0.002) values had significant differences between the three groups. Significant predictive factor(s) for each group were hemoglobin for SVR (OR: 1.517; 95% CI: 1.233-1.868; P < 0.001), IL-28b genotype for relapse (OR: 0.577; 95% CI: 0.339-0.981; P = 0.041) and hemoglobin (OR: 0.824; 95% CI: 0.693-0.980; P = 0.017) and IL-28b genotype (OR: 2.584; 95% CI: 1.430-4.668;P = 0.001) for non-response. The accuracy of ANN to predict SVR, relapse and non-response were 93%, 90%, and 90%, respectively. CONCLUSIONS Using baseline laboratory data and host characteristics, ANN has been shown as an accurate model to predict treatment outcome, which can lead to appropriate decision making and decrease the frequency of ineffective treatment in patients with chronic hepatitis C virus (HCV) infection.
