RESUMEN
BACKGROUND AND AIMS: The aim of this study was to assess the real-life effectiveness and safety of direct acting antivirals (DAAs) in patients with cirrhosis and history of hepatic decompensation compared to those with compensated cirrhosis. METHOD: Data of patients treated with DAAs and included in the EpiTer-2 database (N = 10 152) were collected retrospectively. The primary endpoint was sustained viral response (SVR) at 12 weeks posttreatment. Patients were also evaluated in terms of liver-related adverse events and treatment modification/discontinuation. RESULTS: The overall SVR rate was 91.4% in the intent to treat (ITT) analysis and 95.2% in the per-protocol (PP) analysis (P < .001). Patients with decompensated cirrhosis had lower SVR rates compared to those with compensated cirrhosis in ITT analysis (86.4% vs 92.0%, P < .001), while not in PP analysis (92.9% vs 95.5%, P > .05). Adverse events (AE) occurred 45.6% and 29.3% of patients with decompensated and compensated cirrhosis (P < .001). Patients with decompensated cirrhosis were at higher risk of death (5.4% vs 0.9%; P < .0001) or liver decompensation (21.5% vs 1.3%; P < .0001). Treatment with protease inhibitors was not associated with hepatic decompensation (P = .3). Only 82.6% of patients with decompensated cirrhosis completed DAA treatment (vs 92.8% in compensated cirrhotics; P < .0001). CONCLUSION: Despite higher frequency of AE and treatment modifications, once completed, DAAs yield comparable results for patients with decompensated and compensated cirrhosis. High rate of serious adverse events in patients with advanced liver disease treated with PI may not be related to the detrimental effect of the medications, but rather to the disease itself.

BACKGROUND AND AIM: Grazoprevir/elbasvir (GZR/EBR) was approved for the treatment of chronic hepatitis C virus (HCV) genotype 1 and 4 infected patients with or without compensated liver cirrhosis. The aim of this study was to assess GZR/EBR regimen in the real-world experience, particularly in previously "difficult-to-treat" patients with chronic kidney diseases, human immunodeficiency virus-coinfected, cirrhotics, and treatment-experienced. METHODS: The analysis included patients treated with GZR/EBR selected from 10 152 individuals from the EpiTer-2 database, large national real-world study evaluating antiviral treatment in 22 Polish hepatology centers between 2015 and 2018. Data were completed retrospectively and submitted online. RESULTS: A total of 1615 patients who started GZR/EBR therapy in 2017 and 2018 with a female predominance (54%) and median age of 54 years were analyzed. The majority were infected with GT1b (89%) and treatment naïve (81%). Liver cirrhosis was diagnosed in 19%, and 70% of patients had comorbidities, of which chronic renal disease was present in 7% and HIV-coinfection in 4%. Overall, a sustained virologic response (SVR) was achieved by 95% according to intent-to-treat (ITT) and 98% after exclusion of lost to follow up (modified ITT). No differences were found in cure rate between all included patients and subpopulations previously considered as difficult-to-treat. Majority of patients completed the treatment course as scheduled, adverse events were mostly mild and did not lead to therapy discontinuation. CONCLUSIONS: GZR/EBR treatment carried-out in patients infected with HCV genotype 1 and 4 demonstrated good tolerability and an excellent SVR rate with no effectiveness reduction in so called difficult-to-treat populations.

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 â PrODR- 100%; BOC â LSR - 98%; TVR â PrODR - 97%; TVR â LSR - 96% (intent-to treat analysis-ITT) and BOC â PrODRâ100%; BOC â LSR - 99%; TVR â PrODR - 99%; TVR â 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.

Hepatocellular carcinoma (HCC) is the fifth most common malignancy and the third leading cause of cancerrelated mortality worldwide. Risk factors for this malignancy include liver cirrhosis, HBV or HCV infection, fatty liver disease. THE AIM OF STUDY: This study aims to assess the occurrence and clinical characteristics of HCC in the Northeastern Poland between 2011 and 2015. The number of primary lesions, their size and location within the liver were analysed. The risk factors for this cancer in studied population have been identified. The usefulness of AFP screening and imaging studies for the diagnosis of HCC were assessed. A preliminary analysis of the efficacy of anti-tumour therapy was performed. RESULTS: Sixty-seven patients (28% female and 72% male) with diagnosed HCC were enrolled. HCC diagnosis was established according to the criteria proposed by the International Consensus Group for Hepatocellular Neoplasia. Of the 67 patients in the study, 7 (10%) were aged 30 to 50 years and 60 patients (90%) were aged 51 years and older. During the period 2011-2015, an increase in HCC incidence was observed. In studied group the most prevalent (31%) were patients with 2 tumours localised in the 6th, 7th or 8th segments of the liver. Metastatic tumours were present in 15% and portal vein thrombosis in 9% of patients. Risk factors assessment revealed that in 72% of patients HCC coexisted with cirrhosis, 33% of patients were HCV-infected, 30% had HBV infection, and 15% were diagnosed with NASH. Elevated serum AFP level was observed in 83% of patients with liver cirrhosis, and in 58% of patients without cirrhosis (p <0.05). Liver transplantation was the best therapeutic option. The efficacy of ablation/resection in combination with sorafenib vs. ablation/partial resection was comparable. CONCLUSION: There has been an increase in the number of HCC cases in North-eastern Poland in last few years. HCC is more common in men aged 50 years and older. Increased serum AFP level is a useful marker for the diagnosis and monitoring of HCC treatment in patients with liver cirrhosis.
RESUMEN
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.
RESUMEN
HCV infection is one of the main reasons for liver cirrhosis and hepatocellular carcinoma. In recent years, one finds more and more extrahepatic manifestations of HCV infection, including its possible influence on the development of diabetes. In the presented work, one finds the frequency analysis of the incidence of diabetes among 2898 HCV infected patients treated in Poland, and the assessment of their relevance to the HCV genotype and the progression of fibrosis. The results indicate that the hepatitis C infection seems to be a risk factor for diabetes in persons with more advanced liver fibrosis, for older people, and for the male gender. Thus, one found no differences regarding the frequency of its incidence depending on HCV genotype, including genotype 3.
RESUMEN
Hepatitis C infection is one of the main reasons for liver cirrhosis and hepatocellular carcinoma. In recent years, more and more is being heard about extrahepatic manifestations of the hepatitis C infection including its possible influence on the development of hypertension and cardiovascular diseases. In the given work, the frequency analysis of the incidence of hypertension and cardiovascular diseases among 2898 HCV-infected patients treated in Poland and the assessment of their relevance to the HCV genotype and the progression of liver fibrosis can be found. The prevalence of hypertension in the group of analyzed patients was 39% and was significantly associated with old age (OR = 1.08 (1.07-1.08)) and female sex, as well as the progression of liver fibrosis (OR = 1.54 (1.29-1.85)). Hypertension was found in 47.6% of patients with F4 fibrosis, 42.1% of patients with F3 fibrosis, and 25% of patients with F1 fibrosis. The incidence of cardiovascular disease in the studied group of patients was as follows: all incidents, 131 (4.52%); including ischemic heart disease 104, (3.95%); stroke, 2 (0.07%); atherosclerosis, 21 (0.72%); and aneurysms, 4 (0.14%). The obtained results prove that the prevalence of cardiovascular diseases is significantly associated with the advanced age of patients and the progression of liver fibrosis. The relevance of sex and the HCV genotype to the prevalence frequency of cardiovascular diseases in the study group has not been proven. This being the case, no differences in the frequency of their incidence depending on the HCV genotype, including genotype 3, was found. Hepatitis C infection as a non-classical risk factor for cardiovascular disease and hypertension does require further studying.
RESUMEN
BACKGROUND: The introduction of direct-acting antiviral drugs into clinical practice has revolutionized the treatment of chronic hepatitis C, making it highly effective and safe for patients. However, few researchers have analyzed the factors causing therapy failure in some patients. AIM: To analyze factors influencing the failure of direct antiviral drugs in the large, multicenter EpiTer-2 cohort in a real-world setting. METHODS: The study cohort consisted of patients with chronic hepatitis C treated at 22 Polish centers from 2016-2020. Data collected from the online EpiTer-2 database included the following: hepatitis C virus (HCV) genotype, stage of fibrosis, hematology and liver function parameters, Child-Turcotte-Pugh and Model for End-stage Liver Disease scores, prior antiviral therapy, concomitant diseases, and drugs used in relation to hepatitis B virus (HBV) and/or human immunodeficiency virus (HIV) coinfections. Adverse events observed during the treatment and follow-up period were reported. Both standard and machine learning methods were used for statistical analysis. RESULTS: During analysis, 12614 patients with chronic hepatitis C were registered, of which 11938 (mean age: 52 years) had available sustained virologic response (SVR) data [11629 (97%) achieved SVR and 309 (3%) did not]. Most patients (78.1%) were infected with HCV genotype 1b. Liver cirrhosis was diagnosed in 2974 patients, while advanced fibrosis (F3) was diagnosed in 1717 patients. We included patients with features of hepatic failure at baseline [ascites in 142 (1.2%) and encephalopathy in 68 (0.6%) patients]. The most important host factors negatively influencing treatment efficacy were liver cirrhosis, clinical and laboratory features of liver failure, history of hepatocellular carcinoma, and higher body mass index. Among viral factors, genotype 3 and viral load also exerted an influence on treatment efficacy. Classical statistical analysis revealed that treatment ineffectiveness seemed to be influenced by the male sex, which was not confirmed by the multivariate analysis using the machine learning algorithm (random forest). Coinfection with HBV (including patients with on-treatment reactivation of HBV infection) or HIV, extrahepatic manifestations, and renal failure did not significantly affect the treatment efficacy. CONCLUSION: In patients with advanced liver disease, individualized therapy (testing for resistance-associated variants and response-guided treatment) should be considered to maximize the chance of achieving SVR.

PURPOSE: Since 2017 treatment-naïve patients infected with genotype 1b of hepatitis C virus and minimal or moderate fibrosis can be treated with Ombitasvir/Paritaprevir/ritonavir + Dasabuvir (OPrD) for 8 weeks according to updated Summary of Product Characteristics. The aim of our study was to assess the comparative efficacy of 8 and 12-weeks therapy with OPrD in large cohort of patients eligible for 8 weeks regimen treated in real-world setting. MATERIALS AND METHODS: We analysed data of 3067 HCV genotype 1b infected patients treated with OPrD between 2015 and 2017. Final analysis included patients with none, minimal or moderate fibrosis (F0-F2). RESULTS: A total of 771 patients were enrolled in the study, including 197 (26%) treated for 8-weeks and 574 patients fulfilling criteria for 8-weeks but assigned to 12-weeks regimen. Majority of patients had no or minimal fibrosis (F0-F1). Longer treatment duration was more often administered in patients with moderate fibrosis, comorbidities, concomitant medications. SVR was achieved in 186 (94%) patients treated for 8 weeks and 558 (97%) for 12 weeks (p = 0.07). After exclusion of lost to follow-up patients, sustained virological response (SVR) rate reached 95% and 99%, respectively (p = 0.01). We were not able to identify factors associated with non-response. CONCLUSIONS: This real-word experience study confirmed similar, high effectiveness of 8 and 12-weeks regimens of OPrD in genotype 1b HCV infected patients with non-advanced fibrosis. Despite of reduced SVR rate after 8-weeks regimen, there is no need to extend therapy to 12-weeks in vast majority of such patients and no need to add ribavirin.

OBJECTIVES: The aim of the study was to analyze the prevalence and clinical characteristics of HCV/HBV coinfection and to evaluate the rate of HBV-reactivation during anti-HCV therapy in a large real-world study. METHODS: Analyzed population consisted of 10,152 chronic hepatitis C patients treated with DAA between 2015 and 2019 in a nationwide study. Prior to the DAA all subjects had HBsAg and 60% anti-HBc testing. RESULTS: 111 of 10,152 patients (1.1%) had detectable HBsAg and 1239 of 6139 (20.2%) anti-HBcAb. The prevalence of occult hepatitis B was 0.48%. HCV/HBV patients were younger with a higher proportion of males, HIV-coinfected, and advanced fibrosis. They were less often diagnosed with diabetes but more often with chronic kidney disease. In HBsAg(+) subjects with baseline HBV-DNA available 6/102 (5.9%) HBV-reactivations during or after DAA therapy were observed, and in two (1.9%) significant hepatic flares were noted. In HBsAg(-)/anti-HBc(+) group 2 (0.16%) reactivations were observed only in patients undergoing immunosuppressive therapy. DISCUSSION: Data from a large European cohort suggest a relatively low risk of HBV-reactivation during DAA-therapy for HCV infection in HBsAg(+) patients. In HBsAg(-)/anti-HBc(+) HBV-reactivation seems to be limited to subjects with immunodeficiency. Importantly, previous exposure to HBV and occult hepatitis B is present in a significant proportion of HCV-infected.

The aim of the study is to analyze treatments available for patients infected with genotype (G) 3 hepatitis C virus (HCV) in Poland at the beginning of the interferon (IFN)-free era and evaluate the efficacy and safety of different therapeutic options administered in a real-world setting. 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.

We describe a 27-year-old hepatitis B virus (HBV)-infected pregnant woman, with a history of miscarriage a year ago. The patient has been HBsAg and HBeAg positive for 20 years but has never been treated for HBV infection, because of stable elevated alanine aminotransferase (ALT) activity and high viral load. Treatment with tenofovir disoproxil was introduced in the 10th week of pregnancy and HBV DNA became undetectable. The clinical course of pregnancy was normal and the patient gave birth by caesarean section to a healthy child. At birth the newborn was HBsAg negative, after 3 months of follow-up is healthy, and evaluation of HBV status will be scheduled shortly. The decision to treat HBV infection during pregnancy should be individualized.
