Real-world experience with direct-acting antiviral therapy in HCV-infected patients with cirrhosis and esophageal varices. Pharmacol Rep 2024:10.1007/s43440-024-00639-9. [PMID: 39162985 DOI: 10.1007/s43440-024-00639-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2024] [Revised: 08/11/2024] [Accepted: 08/12/2024] [Indexed: 08/21/2024]
Abstract
BACKGROUND Hepatitis C virus (HCV) infection affects 50 million people worldwide with around 242,000 deaths annually, mainly due to complications such as cirrhosis and hepatocellular carcinoma (HCC). Portal hypertension (PH) caused by cirrhosis leads to severe consequences, including esophageal varices (EV). This study aimed to evaluate the effectiveness and safety of direct-acting antiviral (DAA) treatment in patients with and without EV. METHODS This retrospective analysis involved consecutive HCV-infected adults undergoing DAA therapy at 22 Polish hepatology centers from July 1, 2015, to December 31, 2022. Patients with cirrhosis were categorized based on the presence of EV diagnosed by gastroscopy. Treatment effectiveness was measured by sustained virologic response (SVR), with safety outcomes monitored for 12 weeks post-treatment. RESULTS A population of 3393 HCV-infected patients with cirrhosis was divided into groups with (A, n = 976) and without (B, n = 2417) EV. Group A showed a significantly higher prevalence of comorbidities and concomitant medications. Genotype (GT)1b infections predominated in both groups, and GT3 infections were more common in the EV group. Group A exhibited more severe liver disease, and higher rates of decompensation, HCC, and HBV co-infection. SVR was significantly higher in group B (91.5% vs. 96.3%, p < 0.0001). Male gender, GT3, EV presence, and Child-Pugh grade B were identified as independent negative SVR predictors. Group A had a worse safety profile, with notably higher adverse event incidence and mortality. CONCLUSIONS DAA therapies are highly effective and well tolerated in patients with cirrhosis, but EV presence predicts poorer virologic responses.

Abstract
BACKGROUND The introduction of direct-acting antivirals (DAAs) with their effectiveness and safety has revolutionized the approach to treating hepatitis C virus (HCV) infections. Nevertheless, elderly patients have often been excluded from clinical trials, so the results of real-world studies are particularly important in the context of the geriatric population. The study aimed to analyze the effectiveness and safety of antiviral DAA treatment in HCV-infected patients over the age of 65, with notable inclusion of those over the age of 85. METHODS The analyzed patients were divided by age into three groups: group A (65-74 years), group B (75-84 years) and group C (85 years or older). Patients started DAA based therapy at 22 hepatology centers between July 2015 and December 2022. RESULTS A total of 3505 elderly patients were included in the analysis, and this group consisted of 2501 patients in group A, 893 in group B, and 111 in group C. The study population, regardless of age, was dominated by women. Patients had a high prevalence of comorbidities (84.9%, 92.2%, and 93.7%, respectively) as well as a high rate of concomitant medications. The sustained virological response was 97.9% in groups A and B and 100% in group C. The therapy was well-tolerated, with a comparable safety profile observed in all analyzed groups. CONCLUSIONS DAA-based therapies are highly effective and well tolerated by the elderly patients, including those over 85. Age should not be a barrier to treatment, but careful management is necessary.

Does a detectable HCV RNA at the end of DAA therapy herald treatment failure? Antiviral Res 2023; 220:105742.

Abstract
BACKGROUND & AIMS The study aimed to assess the phenomenon of achieving sustained virologic response (SVR) in patients with detectable ribonucleic acid (RNA) of hepatitis C virus (HCV) at the end of treatment (ET) with direct-acting antivirals (DAA), find how this is affected by the type of regimen, and how patients experiencing this differed from non-responders with detectable HCV RNA at the ET. METHODS The study included all consecutive patients with detectable HCV RNA at the ET selected from the EpiTer-2 database, a retrospective national multicentre project evaluating antiviral treatment in HCV-infected patients in 2015-2023. RESULTS Of the 16106 patients treated with IFN-free regimens with available HCV RNA assessment at the ET and at follow-up 12 weeks after treatment completion (FU), 1253 (7.8%) had detectable HCV RNA at the ET, and 1120 of them (89%) finally achieved SVR. This phenomenon was significantly more frequent in pangenotypic regimens, 10.3% vs. 4.7% in genotype-specific options (p < 0.001), and the highest proportion was documented for glecaprevir/pibrentasvir (13.7%), and velpatasvir/sofosbuvir ± ribavirin (6.9%). Patients ET + FU- treated with these two pangenotypic regimens (n = 668) had less advanced liver disease, were less frequently infected with genotype (GT) 3, and were significantly more likely to be treatment-naïve than 61 non-responders. CONCLUSIONS We documented 7.8% rate of patients with detectable HCV RNA at the ET, of whom 89% subsequently achieved SVR, significantly more frequently in the population treated with pangenotypic regimens. Less severe liver disease, more often GT3 infection, and a higher percentage of treatment-naive patients distinguished this group from non-responders.

Abstract
Aim of the study Despite the excellent effectiveness of direct-acting antivirals (DAA) in the treatment of hepatitis C virus (HCV) infection, still a few percent of patients fail therapy. The study aimed to determine the effectiveness of triple vs double rescue treatment in such a population. Material and methods The study included all consecutive DAA-experienced patients retreated with pangenotypic options from the EpiTer-2 database, a retrospective national multicenter real-world project evaluating antiviral treatment in HCV-infected patients in 2015-2023. Results The studied population consisted of 269 patients, of whom 208 were treated with the double (P2) and 61 with the triple (P3) pangenotypic option. No statistically significant differences were found between these subpopulations, except a significantly more frequent history of liver transplantation in the P3 group (6.6% vs. 0.5%, p = 0.01). In the P2 group, two-thirds of patients were treated with velpatasvir/sofosbuvir, while in the P3 group the majority of patients received a combination of velpatasvir/sofosbuvir/voxilaprevir. Virological response at the end of therapy was comparable in both analyzed subpopulations, but the sustained virologic response (SVR) rate was significantly higher in triple retherapy, 98.3% vs. 88.7%, p = 0.02, calculated after exclusion of patients lost to follow-up. Lower SVR was achieved in genotype 3-infected men with cirrhosis, 88.9% and 80% in P3 and P2, respectively. Conclusions A comparison of double and triple pangenotypic retherapy in patients after failure of DAA therapy showed a higher sustained virological response in the triple option with a comparable response at the end of therapy. The factors reducing the chances of cure were cirrhosis, genotype 3 infection and male gender.

Abstract
BACKGROUND Nearly 290000 patients with chronic hepatitis C die annually from the most severe complications of the disease. One of them is liver cirrhosis, which occurs in about 20% of patients chronically infected with the hepatitis C virus (HCV). Direct-acting antivirals (DAAs), which replaced interferon (IFN)-based regimens, significantly improved the prognosis of this group of patients, increasing HCV eradication rates and tolerability of therapy. Our study is the first to assess changes in patient profile, effectiveness, and safety in the HCV-infected cirrhotic population in the IFN-free era.
AIM To document changes in patient characteristics and treatment regimens along with their effectiveness and safety profile over the years.
METHODS The studied patients were selected from 14801 chronically HCV-infected individuals who started IFN-free therapy between July 2015 and December 2021 in 22 Polish hepatology centers. The retrospective analysis was conducted in real-world clinical practice based on the EpiTer-2 multicenter database. The measure of treatment effectiveness was the percentage of sustained virologic response (SVR) calculated after excluding patients lost to follow-up. Safety data collected during therapy and the 12-wk post-treatment period included information on adverse events, including serious ones, deaths, and treatment course.
RESULTS The studied population (n = 3577) was balanced in terms of gender in 2015-2017, while the following years showed the dominance of men. The decline in the median age from 60 in 2015-2016 to 57 years in 2021 was accompanied by a decrease in the percentage of patients with comorbidities and comedications. Treatment-experienced patients dominated in 2015-2016, while treatment-naive individuals gained an advantage in 2017 and reached 93.2% in 2021. Genotype (GT)-specific options were more prevalent in treatment in 2015-2018 and were supplanted by pangenotypic combinations in subsequent years. The effectiveness of the therapy was comparable regardless of the period analyzed, and patients achieved an overall response rate of 95%, with an SVR range of 72.9%-100% for the different therapeutic regimens. Male gender, GT3 infection, and prior treatment failure were identified as independent negative predictors of therapeutic success.
CONCLUSION We have documented changes in the profile of HCV-infected cirrhotic patients over the years of accessibility to changing DAA regimens, confirming the high effectiveness of IFN-free therapy in all analyzed periods.

Abstract
INTRODUCTION Non-cirrhotic treatment-naive hepatitis C patients infected with genotype 1 can be treated with ledipasvir/sofosbuvir (LDV/SOF) for 8 weeks, but in practice this regimen is frequently extended up to 12 weeks at least in part due to insufficient real-world data supporting shortening of treatment. The aim of our study was to compare 8- and 12-week regimens' efficacy in patients eligible for 8-week therapy in a real-world setting. MATERIAL AND METHODS Data of HCV genotype 1 infected patients treated with LDV/SOF between 2015 and 2018 included in the EpiTer-2 database were analyzed with respect to patients' characteristics and length of treatment. RESULTS Among a total of 1718 patients treated with LDV/SOF, 679 were included in the analysis, 238 (35%) received 8-week regimen, whereas 441 were treated for 12 weeks although they fulfilled the criteria for a shorter course. The majority of patients were infected with genotype 1b (89%) and demonstrated minimal fibrosis (55%). The 12-week regimen was assigned significantly more frequently to patients with comorbidities, concomitant medications and advanced liver fibrosis. The sustained virologic response rate was similar after 8 (98%) and 12 (97%) weeks of therapy according to intent-to-treat analysis and reached 99% in both groups after exclusion of patients lost to follow-up. CONCLUSIONS We confirmed high effectiveness regardless of treatment duration with LDV/SOF in non-cirrhotics infected with HCV genotype 1 eligible for the 8-week regimen according to the current label. This real-world study also demonstrated no need for addition of ribavirin (RBV) in this population and showed that shortening of treatment significantly improves the safety profile of LDV/SOF medication.

We analyzed data of 198 patients who started antiviral therapy after July 1, 2015, and completed it before December 31, 2016; 57.6% of them had liver cirrhosis and 46% were treatment experienced. Fifty percent of patients were assigned to sofosbuvir (SOF)+pegylated IFN alfa (PegIFNa)+ribavirin (RBV), 9% to PegIFNa+RBV, 36% received SOF+RBV, and 5% SOF+daclatasvir (DCV)±RBV. Cirrhotic patients were assigned more frequently to IFN-free regimens. Overall, a sustained virological response was achieved by 84.3% of patients in intent-to-treat (ITT) analysis and 87% in modified ITT analysis. For SOF+PegIFNa+RBV and SOF+DCV±RBV regimens, the sustained virologic response (SVR) rate reached at least 90%, whereas the two other therapeutic options demonstrated efficacy <80%. The SVR rate in noncirrhotics was higher than in cirrhotics, irrespective of regimen. Adverse events were documented in 52.5%, with the most common being weakness/fatigue and anemia. We confirmed effectiveness and safety of the SOF-based treatment in a real-world cohort of patients with chronic HCV G3 infection. Most notably, we demonstrated good tolerability and high efficacy of the SOF+PegIFNa+RBV regimen.

BMC Infect Dis 2018; 18:580. [PMID: 30445916 PMCID: PMC6240185 DOI: 10.1186/s12879-018-3465-2] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2018] [Accepted: 10/31/2018] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND According to the EASL and AASLD guidelines, the recommended treatment for patients who failed to achieve a sustained virologic response (SVR) on prior interferon-based triple therapy with protease inhibitors (PI), is a combination of sofosbuvir and NS5A inhibitors. Polish national recommendations also allow the use of paritaprevir/ritonavir/ombitasvir+dasasbuvir±ribavirin (PrODR) in this group of patients. The aim of the study was to evaluate the efficacy and safety of PrODR vs. ledipasvir/sofosbuvir±RBV (LSR) in PI-experienced patients in real-life setting. METHODS Our analysis included patients registered in the nationwide, investigators initiated, multicentre EpiTer-2 database. Among 4530 patients registered, 335 with genotype 1 (93% 1b) were previously treated with IFN-based regimens with PIs: 127 with boceprevir (BOC), 208 with telaprevir (TVR). Patients with advanced fibrosis (F3/F4) were significantly predominant (BOC 28.4%/61.4%, TVR 18.8%/64.4%, respectively). Subjects were assigned to IFN-free retreatment as follows: BOC - 64 (50.4%) PrODR and 63 (49.6%) LSR; TVR- 103 (49.5%) PrODR and 105 (50.5%) LSR. RESULTS SVR rates were comparable for particular groups: BOC → PrODR- 100%; BOC → LSR - 98%; TVR → PrODR - 97%; TVR → LSR - 96% (intent-to treat analysis-ITT) and BOC → PrODR→100%; BOC → LSR - 99%; TVR → PrODR - 99%; TVR → LSR - 98% (modified intent-to treat analysis-mITT). Both treatment regimens had a favourable safety profile. Adverse events (AEs) were generally mild or moderate in severity. Three deaths were reported. The treatment was stopped due to AEs in five patients (three treated with PrODR and two with LSR). CONCLUSION Efficacy and safety of treatment with PrODR and LSR is comparable in BOC or TVR-experienced patients.

Abstract
The aim of the EpiTer-2 study was to analyse patient characteristics and their medication for HCV infection in Poland at the beginning of the interferon-free era. Analysis of data of HCV infected patients treated during the initial period of availability of interferon-free regimens in Poland, who started therapy after 1 July 2015 and had available an efficacy evaluation report before 30 June 2017 was undertaken. A total of 2879 patients with chronic hepatitis C were entered, including 46% with liver cirrhosis. The most common was genotype 1b (86.8%). The study population was gender balanced, the majority of patients were overweight or obese and 69% presented comorbidities, with the highest prevalence that for hypertension. More than half of patients were retreated due to failure of previous therapy with pegylated interferon and ribavirin. Almost two-third of patients received current therapy with ombitasvir/paritaprevir/ritonavir±dasabuvir (OPrD) ±ribavirin. Other patients received mostly sofosbuvir-based regimens including combination with ledipasvir and pegylated interferon and ribavirin for genotype 3-infected patients. Efficacy of treatment in the whole study population measured as intent-to-treat analysis was 95%. The most frequent regimen, administered for patients infected with genotype 1b, was 12 weeks of OPrD, resulting in an SVR rate of 98%. At least one adverse event was reported in 38% of patients, and the death rate was 0.8%. In conclusion, data from the EpiTer-2 study confirmed the excellent efficacy and safety profile of the real-world experience with recently introduced therapeutic options for genotype 1 HCV infection, but demonstrated weakness of the current therapeutic programme regarding genotype 3 infections.

PRZEGLAD GASTROENTEROLOGICZNY 2018; 13:22-29. [PMID: 29657607 PMCID: PMC5894449 DOI: 10.5114/pg.2018.74558] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/01/2016] [Accepted: 04/18/2017] [Indexed: 11/17/2022]
Abstract
INTRODUCTION Dual therapy (PegIFN and ribavirin) (DT) was the standard of care in patients infected with HCV genotype 4 (HCV-4) until 2014. Nowadays, new treatment options are available including interferon (IFN)-based and other IFN-free regimens. AIM To assess the efficacy (SVR24) and safety of DT and the selected predictor factors of SVR in HCV-4 infected patients. MATERIAL AND METHODS One hundred and twelve patients (62 men) of median age 23 years were treated with DT for 48/72 weeks (107/5) in the years 2006-2014. Most of them were treatment naïve (80.4%) and with fibrosis F ≤ 2 (83.1%). To select a subset of independent predictors of SVR Logistic Regression Analysis was applied. RESULTS SVR24 was achieved in 46/112 (41.1%) patients. The mean viral load was 5.55 log10 IU/ml. Lack of therapy experience increases the odds of achieving SVR (OR = 4.17; 1.04-16.67), whereas more advanced fibrosis and higher baseline viral load tend to decrease the probability of SVR (OR = 0.05; 0.01-0.52 and OR = 0.44; 0.17-1.13, respectively). In contrast, the weight loss is associated with higher probability of virological response (OR = 4.31; 1.37-13.60). Two hundred and seventy-nine adverse events (AEs) were reported in 96 individuals. The rates and types of AEs were similar in patients treated with PegIFN-α2a/RBV and PegIFN-α2b/RBV. Overall, 3 (2.7%) patients discontinued therapy prematurely because of serious AEs. CONCLUSIONS SVR24 was low. Loss of weight was a new positive predictive factor of SVR found in our study. Most of the AEs were typical of those previously reported for DT.

Abstract
To assess a combination of novel measures of therapeutic success in the treatment of chronic hepatitis C (CHC) infection, we evaluated liver stiffness (LS) with shear wave elastography and hepatitis C virus core antigen (HCVcAg) concentrations. We followed 34 patients during and after treatment with direct acting antivirals. All patients achieved a sustained virologic and serologic response and a significant increase of albumin levels. Decreases of alanine aminotransferase (ALT) activity and alpha-fetoprotein (AFP) level were observed during the treatment and follow-up period. A significant decrease in LS was observed between baseline, end of treatment (EOT), and at 24- and 96-week post-treatment follow-up. LS decline between EOT and 96-week follow-up (FU96) was observed in 79% of patients. Significant LS changes were seen in patients with advanced fibrosis, particularly in cirrhotics and in patients with ALT exceeding 100 IU/mL. There was a positive correlation between ALT activity and LS changes at the baseline versus FU96. A negative correlation was demonstrated between individual HCVcAg baseline concentrations and reduction of LS at the baseline versus FU96. In conclusion, we observed that LS significantly declined during and after antiviral treatment. It was accompanied by improvement in some liver function measures, and disappearance of both HCVcAg and HCV ribonucleic acid (HCV RNA).

Abstract
BACKGROUND To evaluate the effectiveness and safety of ledipasvir/sofosbuvir (LDV/SOF)±ribavirin (RBV) regimen in a real-world setting. METHODS Patients received a fixed-dose combination tablet containing LDV and SOF with or without RBV, for 8, 12 or 24 weeks. Patients were assessed at baseline, end of treatment, and 12 weeks after the end of treatment. The primary effectiveness endpoint was sustained virologic response 12 weeks after the end of treatment (SVR12). RESULTS Of the 86 patients, aged 20-80 years, 82.6% were HCV genotype 1b-infected and 50.0% were cirrhotic. More than half (52.3%) had previously followed pegylated interferon-containing (PEG-IFN) treatment regimens, and 38.5% were null-responders. SVR12 was achieved by 94.2% of patients. All non-responders were cirrhotic: two demonstrated virologic breakthrough and the remaining three relapsed. All patients treated with an 8-week regimen achieved SVR12 despite having high viral load at baseline (HCV RNA of >1 million IU/mL in 8/10 patients, including one with a viral load of >6 million IU/mL). Adverse events were generally mild and transient. Most frequently, fatigue (22.1%), headache (15.1%), and arthralgia (7.0%) were observed. Laboratory abnormalities included anemia and hyperbilirubinemia. CONCLUSIONS Treatment with LDV/SOF±RBV is an effective and safe option for patients with HCV, including those with advanced liver disease or a history of non-response to PEG-IFN-based therapy.

Abstract
The goals of treatment is to eliminate HCV infection, stop or reverse histological changes, reduce the risk of hepatocellular carcinoma development and transmission of the infection to other individuals. According to the recommendation of the Polish Group of Experts for HCV in 2017 all patients with chronic HCV infection should receive treatment, but it is not recommended in patients at high risk of short overall survival. If access to therapy is restricted, priority should be given to patients whose HCV infection can lead to an unfavourable outcome of the disease within a short time frame, particular to individuals with liver cirrhosis, rapidly progressing liver fibrosis, extrahepatic manifestations of HCV infection, chronic kidney diseases, patients before and after organ transplantation. Current recommendations of Polish Group of Experts for HCV provide guidelines to select optimal medication, assessment of liver fibrosis, treatment efficacy, dealing with resistance to direct acting antivirals, monitoring for hepatocellular carcinoma, management of HBV/HCV coinfection and drug interactions. It constains also advice on treatment of special patients populations such as renal failure, liver transplant and hepatic decompensation, as well as retreatment of patients which failed interferon free therapy. Moreover specific recommendations of management patients infected with different genotypes with currently reimbursed regimens or those expected to become available shortly in Poland are also included.

Abstract
BACKGROUND Treatment of chronic hepatitis C genotype 3 (GT3) is more challenging compared with other genotypes. Since 2014, several new treatment regimens have been approved but sometimes based on limited data. AIM To validate the use, effectiveness and safety of anti-viral treatment in chronic hepatitis C genotype 3 infection under real-word conditions. METHODS The German Hepatitis C-Registry is a large national non-interventional real-world study for patients with chronic hepatitis C. A total of 1322 GT3 patients were enrolled (211 untreated and 1111 treated patients). RESULTS Between February 2014 and September 2015, five different treatment strategies have been used (PegIFN+RBV, PegIFN+RBV+SOF, SOF+RBV, DCV+SOF±RBV, LDV/SOF±RBV). Treatment uptake and use of treatment concepts changed markedly and rapidly during the study influenced by new approvals, guideline recommendations, and label updates. PegIFN-based therapies constantly declined while DCV-based therapies increased with one interruption after the approval of LDV/SOF, which was frequently used until new guidelines recommended not using this combination for GT3. Per-protocol SVR ranged from 80.9% in the PegIFN+RBV group to 96.1% in PegIFN+RBV+SOF treated patients. Treatment-experienced patients with cirrhosis showed a suboptimal SVR of 68% for SOF+RBV but a high SVR of 90-95% for DCV+SOF±RBV. The safety analysis showed more adverse events and a stronger decline of haemoglobin for RBV containing regimens. CONCLUSIONS Real-world data can validate the effectiveness and safety for treatment regimens that had previously been approved with limited data, in particular for specific subgroups of patients. The present study demonstrates how rapid new scientific data, new treatment guidelines, new drug approvals and label changes are implemented into routine clinical practice today.

Abstract
THE AIM OF THE STUDY Was to analyze the efficacy achieved with regimens available for chronic hepatitis C (CHC) in Poland between 2013 and 2016. MATERIAL AND METHODS Data were collected from 29 centers and included 6786 patients with available sustained virologic response (SVR) data between 1 January 2013 and 31 March 2016. RESULTS The sustained virologic response rate for genotypes (G) 1a, 1b, 2, 3 and 4 was 62%, 56%, 92%, 67% and 56% respectively; 71% patients (n = 4832) were treated with pegylated interferon α (Peg-IFNα) and ribavirin (RBV), with SVR rates of 58%, 49%, 92%, 67% and 55% respectively. The sustained virologic response among 5646 G1 infected patients was the lowest with natural interferon α (7%, n = 70) or PegIFN (50%, n = 3779) with RBV, and improved in those receiving triple regimens of Peg-IFN + RBV combined with boceprevir (47%, n = 485), telaprevir (64%, n = 805), simeprevir (73%, n = 132) or sofosbuvir (70%, n = 23). The sustained virologic response with interferon-free regimens of sofosbuvir and RBV (n = 7), sofosbuvir and simeprevir (n = 53), and ledipasvir and sofosbuvir (n = 64) achieved 86%, 89% and 94% respectively. The highest SVR of 98% was observed with ombitasvir/paritaprevir combined with dasabuvir (n = 227). Patients infected with G3 (n = 896) and G4 (n = 220) received mostly Peg-IFN + RBV with SVR of 67% and 56% respectively. Interferon-free regimens were administered in 18 G3/G4 patients and all achieved an SVR. Sofosbuvir combined with Peg-IFN and RBV was administered to 33 patients with an SVR rate of 94%, and a similar rate was achieved among 13 G2 patients treated with interferon and RBV. CONCLUSIONS We observed significant differences in efficacy of HCV regimens available in Poland at the turn of the interferon era. The data will be useful as a comparison for therapeutic options expected in the next few years.

Abstract
The aim of the study Was to assess current prevalence of hepatitis C virus (HCV) genotypes in Poland, including their geographic distribution and changes in a given period of time. Material and methods Data were collected with questionnaires from 29 Polish centers and included data of patients diagnosed with HCV infection between 1 January 2013 and 31 March 2016. Results In total, data of 9800 patients were reported. The highest prevalence was estimated for genotype 1b (81.7%), followed by 3 (11.3%), 4 (3.5%), 1a (3.2%) and 2 (0.2%). Genotype 5 or 6 was reported in 6 patients only (0.1%). The highest prevalence of genotype 1 was observed in central (łódzkie, mazowieckie, świętokrzyskie), eastern (lubelskie) and southern (małopolskie, śląskie) Poland. The highest rate for genotype 3 was observed in south-western (dolnośląskie, lubuskie) and eastern (podlaskie, warmińsko-mazurskie and podkarpackie) Poland. Compared to historical data, we observed an increasing tendency of G1 prevalence from 72.0% in 2003 to 87.5% in 2016, which was accompanied by a decrease of G3 (17.9% vs. 9.1%) and G4 (9.0% vs. 3.1%). Conclusions Almost 85% of patients with HCV in Poland are infected with genotype 1 (almost exclusively subgenotype 1b), and its prevalence shows an increasing tendency, accompanied by a decrease of genotypes 3 and 4.

Efficacy and direct costs of chronic hepatitis C treatment with first generation NS3/4A protease inhibitors in a real life population. Clin Exp Hepatol 2016; 2:133-137. [PMID: 28856277 PMCID: PMC5497430 DOI: 10.5114/ceh.2016.63869] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/14/2016] [Accepted: 10/31/2016] [Indexed: 12/01/2022] Open
Abstract
Introduction Recent years have brought a significant advance in chronic hepatitis C (CHC) treatment that includes development of direct acting antivirals (DAA). Two of them, boceprevir (BOC) and telaprevir (TVR), were first approved for treatment of patients infected with CHC genotype 1 in combination with pegylated interferon (P) and ribavirin (R). Our aim was to evaluate the efficacy and direct costs of BOC/PR and TVR/PR in a real life population. Material and methods The study included adult patients qualified for the CHC Therapeutic Programme treated with TVR/PR or BOC/PR. Treatment was continued for 24 or 48 weeks. Sustained virological response, treatment discontinuation due to adverse events and lack of virological response rates were compared. Results A total of 243 adult patients with CHC were included. TVR/PR and BOC/PR were administered in respectively 122 and 121 patients. Thirty-two patients (13%) were treatment-naïve, whereas liver cirrhosis/advanced fibrosis was observed in 138 patients (56.7%). Overall, 43.6% of patients achieved a sustained virologic response (SVR). In the BOC/PR group the SVR rate was significantly lower than in the TVR/PR group (33.1% vs. 54.1%; p = 0.00094). Lack of response to therapy was observed in 41.3% and 12.3% of patients receiving BOC and TVR, respectively (p < 0.00001). The direct cost of achieving SVR in one patient was 285 450 PLN with BOC and 185 757 PLN with TVR. Conclusions The very low treatment efficacy may be the result of inclusion criteria that allowed treatment of patients with advanced liver fibrosis/liver cirrhosis or previous treatment failure. Telaprevir seems to be significantly more potent against hepatitis C virus, with similar safety and tolerance.

Real-world effectiveness and safety of ombitasvir/paritaprevir/ritonavir ± dasabuvir ± ribavirin in hepatitis C: AMBER study. Aliment Pharmacol Ther 2016; 44:946-956. [PMID: 27611776 DOI: 10.1111/apt.13790] [Citation(s) in RCA: 61] [Impact Index Per Article: 7.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/04/2016] [Revised: 07/16/2016] [Accepted: 08/12/2016] [Indexed: 12/31/2022]
Abstract
BACKGROUND Virologic and safety outcomes of ombitasvir/paritaprevir/ritonavir ± dasabuvir ± ribavirin (OBV/PTV/r ± DSV ± RBV) therapy have shown high sustained virologic response (SVR) rates and good tolerability in most patient populations in pre-registration studies. AIM To confirm these clinical trial findings in the treatment of genotype 1 and 4 hepatitis C under real-world conditions. METHODS Patients enrolled for treatment with OBV/PTV/r ± DSV ± RBV based on therapeutic guidelines were included, and the regimen was administered according to product characteristics. Clinical and laboratory data, including virologic response, were collected at baseline, end of treatment (EOT) and 12 weeks after EOT. RESULTS A total of 209 patients with chronic hepatitis C were enrolled, most were genotype 1b-infected (84.2%) and 119 (56.9%) had liver cirrhosis. Among these, 150 (71.7%) had failed previous anti-viral therapies and 84 (40.2%) were null-responders. At 12 weeks after EOT, SVR was achieved by 207 (99.0%) patients, ranging from 96.4% to 100.0% across subgroups. All Child-Pugh B and post-orthotopic liver transplantation patients achieved SVR. Adverse events occurred in 151 (72.2%) patients and were mostly mild and associated with the use of RBV. Serious adverse events, including hepatic decompensation, renal insufficiency, anaemia, hepatotoxicity and diarrhoea, were reported in eight (3.8%) patients. In five (2.4%) patients, adverse events led to treatment discontinuation. On-treatment decompensation was experienced by seven (3.3%) patients. CONCLUSIONS The results of our study confirm previous findings. They demonstrate excellent effectiveness and a good safety profile of OBV/PTV/r± DSV±RBV in HCV genotype 1-infected patients treated in the real-world setting.
