[Participation indicators of colorectal screenings in Hungary between 2008-2021]. / A kolorektális szurések részvételi mutatói Magyarországon 2008­2021 között.

The aim of our study is to analyse the participation indicators of colorectal cancer screening between 2008-2021. Data derived from the nationwide financing database of the Hungarian National Health Insurance Fund Management. We analysed both diagnostic and screening examinations. According to our results, the screening rate was low, varying between 5.1-6.8% in the years examined. Between 2008 and 2019, the number of participating patients increased slightly. The highest number of patients can be observed in 2019 (178,568 people). In 2020 and 2021, we see a significant decrease, which is a consequence of the COVID-19 pandemic. In the number of patients of the entire examined period (2,233,963 people, 938,223 men, 1,295,740 women), the largest proportion was fecal blood detection by immunochemical method (OENO code: 22631). In 2021, at the county level, the highest number of patients can be seen in Csongrád-Csanád county (994 patients/10,000 people), and the least in Békés county (218 patients/10,000 people). The participation rate of women is higher than that of men in all counties. Participation in colorectal screening is very low. In order to prevent colorectal cancer death, it is necessary to increase the participation rate.

HCV Elimination in Central Europe with Particular Emphasis on Microelimination in Prisons.

In 2016, the WHO announced a plan to eliminate viral hepatitis as a public health threat by 2030. In this narrative review, experts from Bulgaria, Croatia, the Czech Republic, Hungary, Latvia, Lithuania, Poland and Slovakia assessed the feasibility of achieving the WHO 2030 target for HCV infections in Central Europe. They focused mainly on HCV micro-elimination in prisons, where the highest incidence of HCV infections is usually observed, and the impact of the COVID-19 pandemic on the detection and treatment of HCV infections. According to the presented estimates, almost 400,000 people remain infected with HCV in the analyzed countries. Interferon-free therapies are available ad libitum, but the number of patients treated annually in the last two years has halved compared to 2017-2019, mainly due to the COVID-19 pandemic. None of the countries analyzed had implemented a national HCV screening program or a prison screening program. The main reason is a lack of will at governmental and prison levels. None of the countries analyzed see any chance of meeting the WHO targets for removing viral hepatitis from the public threat list by 2030, unless barriers such as a lack of political will and a lack of screening programs are removed quickly.

Hepatitis C Screening and Treatment Program in Hungarian Prisons in the Era of Direct Acting Antiviral Agents.

A hepatitis C virus (HCV) screening and treatment program was conducted in Hungarian prisons on a voluntary basis. After HCV-RNA testing and genotyping for anti-HCV positives, treatments with direct-acting antiviral agents were commenced by hepatologists who visited the institutions monthly. Patients were supervised by the prisons' medical staff. Data were retrospectively collected from the Hungarian Hepatitis Treatment Registry, from the Health Registry of Prisons, and from participating hepatologists. Eighty-four percent of Hungarian prisons participated, meaning a total of 5779 individuals (28% of the inmate population) underwent screening. HCV-RNA positivity was confirmed in 317/5779 cases (5.49%); 261/317 (82.3%) started treatment. Ninety-nine percent of them admitted previous intravenous drug use. So far, 220 patients received full treatment and 41 patients are still on treatment. Based on the available end of treatment (EOT) + 24 weeks timepoint data, per protocol sustained virologic response rate was 96.8%. In conclusion, the Hungarian prison screening and treatment program, with the active participation of hepatologists and the prisons' medical staff, is a well-functioning model. Through the Hungarian experience, we emphasize that the "test-and-treat" principle is feasible and effective at micro-eliminating HCV in prisons, where infection rate, as well as history of intravenous drug usage, are high.

Is elimination of HCV in 2030 realistic in Central Europe.

According to the recent data presented by Central-European HCV experts, the estimated prevalence of HCV is between 0.2% and 1.7% in certain countries in this region. There are no financial limitations to access to treatment in most countries. Patients in these countries have access to at least one pangenotypic regimen. The most common barriers to the elimination of HCV in Central Europe are a lack of established national screening programmes and limited political commitment to the elimination of HCV. Covid-19 has significantly affected the number of patients who have been diagnosed and treated, thus, delaying the potential elimination of HCV. These data suggest that the elimination of HCV elimination projected by WHO before 2030 will not be possible in the Central Europe.

How close are we to hepatitis C virus elimination in Central Europe?

AIM OF THE STUDY: To collect and analyse data obtained from HCV opinion leaders/experts from central European countries, on factors which can affect the WHO target of HCV elimination by 2030. MATERIAL AND METHODS: Data were collected from opinion leaders/experts involved in management of HCV infections in Central European countries which participated in 9th Conference of the Central European Hepatologic Collaboration (Warsaw, 10-11 October 2019). A dedicated questionnaire collected current information related to HCV elimination in Bulgaria, Croatia, the Czech Republic, Hungary, Latvia, Lithuania, Poland and Slovakia. RESULTS: The HCV prevalence rate in particular countries varied from 0.2% to 1.7%. In most central European countries all the HCV infected population is eligible for reimbursement of treatment. However, in some countries there are still some limitations related to the stage of the disease and people who inject drugs. All countries have access to at least one pangenotypic regimen. The most common barrier to HCV elimination in all countries is insufficient political will to establish priority for HCV. None of the reporting countries has established a national screening programme. CONCLUSIONS: Access to therapy for HCV is similar and the majority of patients in Central Europe can be treated according to the current guidelines. Unfortunately there are still some limitations and a lack of political will to implement national screening programmes. According to collected data HCV elimination will not be possible in the region by 2030.

Ombitasvir/paritaprevir/ritonavir + dasabuvir + ribavirin in HCV genotype 1 infected patients who failed previous protease inhibitor therapy.

AIM OF THE STUDY: Combination of ombitasvir/paritaprevir/ritonavir + dasabuvir ± ribavirin (3DDA±RBV) therapy is shown to be effective in HCV genotype 1 (GT1) infected patients. However, sparse data exist in patients who failed previous boceprevir or telaprevir based therapies. Real life efficacy and safety of this combination were evaluated in HCV GT1b infected patients (mostly cirrhotics) with compensated liver disease who failed previous boceprevir or telaprevir based therapies more than a year before. MATERIAL AND METHODS: Data of previous protease inhibitor failure patients, treated with 3DAA+RBV for 12 weeks (GT1b and/or non-cirrhotics) or 24 weeks (non-GT1b cirrhotics), were retrospectively collected. RESULTS: Population characteristics: boceprevir/telaprevir-failure: 82/45, GT1b: 117, cirrhotic: 111 (87.4%). SVR12/24 was observed in 103/105 patients (98.1%) of those who reached either time point. Four SAEs reported: one death due to myocardial infarction, another due to recurrent hepatocellular carcinoma after achieving SVR12, two hospitalizations (elevation of transaminases, pneumonia). Grade ≥ 3 AEs or laboratory abnormalities were reported in < 10% of patients; they were transient in all patients. No early discontinuation of drugs due to SAE has been reported. CONCLUSIONS: One year after previous failure of boceprevir or telaprevir based therapy, 12 weeks of 3DAA+RBV combination in HCV GT1b infected patients is similarly effective and safe as in those with no previous HCV therapy, even in the presence of cirrhosis. These findings might be of particular interest in settings where alternative therapies for such patients are not available or not affordable.

The treatment of hepatitis C is based on a national consensus guideline updated six-monthly according to local availability and affordability of approved therapies through a transparent allocation system in Hungary. This updated guideline incorporates some special new aspects, including recommendations for screening, diagnostics, use and allocation of novel direct acting antiviral agents. The indication of therapy in patients with no contraindication is based on the demonstration of viral replication with consequent inflammation and/or fibrosis in the liver. Non-invasive methods (elastographies and biochemical methods) are preferred for liver fibrosis staging. The budget allocated for these patients is limited. Interferon-based or interferon-free therapies are available for the treatment. Due to their limited success rate as well as to their (sometimes severe) side-effects, the mandatory use of interferon-based therapies as first line treatment can not be accepted from the professional point of view. However, they can be used as optional therapy in treatment-naïve patients with mild disease. As of interferon-free therapies, priority is given to those with urgent need based on a pre-defined scoring system reflecting mainly the stage of the liver disease, but considering also additional factors, i.e., hepatic decompensation, other complications, activity and progression of liver disease, risk of transmission and other special issues. Approved treatments are restricted to the most cost-effective combinations based on the cost per sustained virological response value in different patient categories with consensus amongst treating physicians, the National Health Insurance Fund of Hungary and patients' organizations. Interferon-free treatments and shorter therapy durations are preferred. Orv Hetil. 2018; 159(Suppl 1): 3-23.

Diagnosis and treatment of hepatitis B virus (HBV) and hepatitis D virus infection mean for the patient to be able to maintain working capacity, to increase quality of life, to prevent cancer, and to prolong life expectancy, while the society benefits from eliminating the chances of further transmission of the viruses, and decreasing the overall costs of serious complications. The guideline delineates the treatment algorithms from 22 September 2017 set by a consensus meeting of physicians involved in the treatment of these diseases. The prevalence of HBV infection in the Hungarian general population is 0,5-0,7%. The indications of treatment are based upon viral examinations (including viral nucleic acid determination), determinations of disease activity and stage (including biochemical, pathologic, and/or non-invasive methods), and excluding contraindications. To avoid unnecessary side effects and for a cost-effective approach, the guideline stresses the importance of quick and detailed virologic evaluations, the applicability of transient elastography as an acceptable alternative of liver biopsy in this regard as well as the relevance of appropriate consistent follow-up schedule for viral response during therapy. The first choice of therapy in chronic HBV infection can be pegylated interferon for 48 weeks or continuous entecavir or tenofovir therapy. The latter two must be continued for at least 12 months after hepatitis B surface antigen seroconversion. Lamivudine is no longer the first choice; patients currently taking lamivudine must switch if the response is inadequate. Appropriate treatment of patients taking immunosuppressive medications is highly recommended. Pegylated interferon based therapy is recommended for the treatment of concomitant hepatitis D infection. Orv Hetil. 2018; 159(Suppl 1): 24-37.

Patterns of Resistance-Associated Substitutions in Patients With Chronic HCV Infection Following Treatment With Direct-Acting Antivirals.

BACKGROUND & AIMS: Little is known about substitutions that mediate resistance of hepatitis C virus (HCV) to direct-acting antivirals (DAAs), due to the small number of patients with treatment failure in approval studies. It is important to identify resistance patterns to select effective salvage treatments. METHODS: We performed a comprehensive analysis for resistance-associated substitutions (RASs) in HCV genes (nonstructural protein [NS]3, NS5A, NS5B) targeted by DAAs. We compared NS3, NS5A, and NS5B sequences from 626 patients in Europe with DAA failure with sequences from 2322 DAA-naïve patients, infected with HCV genotypes 1 to 4. We considered RASs to be relevant if they were associated with DAA failure in patients or conferred a greater than twofold change in susceptibility compared with a reference strain in in vitro replicon assays. Data were collected on pretreatment status, DAA regimen, the treatment initiation date and duration, and virologic response. Patients who received at least 4 weeks of antiviral treatment were included in the analysis. RESULTS: RASs in NS3 associated with simeprevir or paritaprevir failure include R155K and D168E/V. In addition, several RASs were specifically associated with failure of simeprevir (Q80K/R in patients with genotype 1a or 4) or paritaprevir (Y56H in combination with D168V in patients with genotype 1b). Y93H in NS5A was the RAS most frequently associated with failure of daclatasvir, ledipasvir, or ombitasvir in patients with genotype 1b infection, and L31M was associated with failure of daclatasvir or ledipasvir, but not ombitasvir. RASs in NS5A were heterogeneous among patients with HCV genotype 1a or genotype 4 infections. In patients with HCV genotype 3, Y93H was associated with resistance to daclatasvir, but no RASs were associated with ledipasvir failure, pointing to a limited efficacy of ledipasvir in patients with genotype 3. Among patients failed by sofosbuvir-containing regimens, L159F was enriched in patients with genotype 1b (together with C316N) or genotype 3 infection, whereas the RAS S282T was rarely observed. CONCLUSIONS: We compared RASs in NS3, NS5A, and NS5B among patients failed by DAA therapy. Theses varied with the HCV genotype and subtype, and the different drug classes. These findings might be used to select salvage therapies.

[Efficacy and safety of boceprevir based triple therapy in Hungarian patients with hepatitis C genotype 1 infection, advanced stage fibrosis and prior treatment failure]. / Bocepreviralapú hármas kezelés hatékonyságának és biztonságosságának retrospektív elemzése elorehaladott fibrosisstádiumú, hepatitis C-vírus 1-es genotípussal fertozött, korábban sikertelenül kezelt magyar betegeknél.

INTRODUCTION: During 2011 and 2013, 155 Hungarian hepatitis C genotype 1 infected patients, mostly with advanced liver fibrosis, who did not respond to prior peginterferon + ribavirin dual therapy, started boceprevir based triple therapy in an early access program. AIM AND METHOD: Efficacy and safety of the therapy was retrospectively assessed based on sustained virologic responses, as well as on frequency and type of serious adverse events and of those leading to therapy discontinuation. RESULTS: In an intent-to-treat analysis 39.4% patients (61/155) reached sustained virologic response. Amongst pervious relapsers, partial responders and null-responders 59.5%, 41.4 % and 22.9% (p<0.05 compared to the other two categories) reached sustained virologic response, respectively, while amongst non-cirrhotics and cirrhotics 52.5% and 31.3% (p<0.05 compared to the non-cirrhotics) achieved sutained virologic response, respectively. Six out of the 33 most difficult to cure patients (previous null responder and cirrhotic) have reached sustained virologic response (18.2%). Frequency of early discontinuations due to insufficient virologic response was 31.1%, while due to adverse event 10.3%. Reported frequency of serious adverse event was 9.8%. These events represented anemia, diarrhoea, depression, agranulocytosis, elevated aminotransferases, generalized dermatitis and severe gingivitis with loss of teeth, prolonged QT interval on ECG, generalized oedema and severe dyspnoea, uroinfection, exacerbation of Crohn's disease, Campylobacter pylori infection and unacceptable weakness and fatigue. Eight patients received transfusion, 4 patients erythropoietin and 1 granulocyte colony stimulating factor during therapy. No death has been reported. CONCLUSIONS: With boceprevir based triple therapy, one of the bests available in 2011-2013 in Hungary, a relevant proportion of hepatitis C infected patients with advanced liver fibrosis achieved sustained viral response. In this cohort, side-effects resembled those reported in registration studies, and resulted in therapy discontinuation with consequent treatment failure in a relevant number of patients. Efficacy and tolerability of boceprevir-based triple therapy are suboptimal, particularly in the most difficult to cure patient population. Orv. Hetil., 2016, 157(34), 1366-1374.

Epidemiology of HCV infection in the Central European region.

Opinion leaders in each of four countries in the Central European region summarize the available data on hepatitis C virus (HCV) epidemiology. The overall prevalence of anti-HCV antibody reactivity in this region varies between 0.2% and 2.1%, the most prevalent HCV genotype is GT 1. The commonest route of transmission is intravenous drug abuse at present.

Hepatology topics of special interest from Central Europe (Czech Republic, Hungary, Poland, Slovakia).

This compilation represents abstracts of presentations at the first meeting of the Initiative Group for the Central European Hepatologic Collaboration (CEHC, Warsaw, 19-21 November, 2015) on topics with special interest from four Central European countries and includes a summary of a boceprevir-based triple therapy cohort programme (from Hungary), current trends and challenges in liver diseases (from Poland), acute kidney injury in liver cirrhosis (from Slovakia) and treatment of hepatitis C in haemodialysed patients (from the Czech Republic). All these topics are or have been of high interest during the last several years, and many of them are still not completely resolved with the emergence and availability of the novel interferon-free therapies for hepatitis C and with other advances in the pathophysiology and treatment of liver diseases.

Approximately 70.000 people are infected with hepatitis C virus in Hungary, more than half of whom are not aware of their infection. From the point of infected individuals early recognition and effective treatment of related liver injury may prevent consequent advanced liver diseases and complications (liver cirrhosis, liver failure and liver cancer) and can increase work productivity and life expectancy on one hand. From socioeconomic aspect, this could also prevent further spread of the virus as well as reduce substantially long term financial burden of related morbidity. Available since 2003 in Hungary, pegylated interferon + ribavirin dual therapy can clear the virus in 40-45% of previously not treated (naïve), and in 5-21% of previous treatment-failure patients. Addition of a direct acting first generation protease inhibitor drug (boceprevir or telaprevir) to the dual therapy increases the chance of sustained virologic response to 63-75% and 59-66%, respectively. These two protease inhibitors are available and financed for a segment of Hungarian patients since May 2013. Between 2013 and February 2015, other direct acting antiviral interferon-free combination therapies have been registered for the treatment of chronic hepatitis C, with a potential efficacy over 90% and typical short duration of 8-12 weeks. Indication of therapy includes exclusion of contraindications to the drugs and demonstration of viral replication with consequent liver injury, i.e., inflammation and or fibrosis in the liver. Non-invasive methods (eleastography and biochemical methods) are accepted and preferred for staging liver damage (fibrosis). For initiation of treatment accurate and timely molecular biology tests are mandatory. Eligibility for treatment is a subject of individual central medical review. Due to budget limitations tharpy is covered only for a proportion of patients by the National Health Insurance Fund. Priority is given to those with urgent need based on a Hungarian Priority Index system reflecting primarily the stage of liver disease, and considering also additional factors, i.e., activity and progression of liver disease, predictive factors of treatment and other special issues. Approved treatments are restricted to the most cost-effective combinations based on the cost per sustained virologic response value in different patient categories with consensus between professional organizations, National Health Insurance Fund and patient organizations. More expensive therapies might be available upon co-financing by the patient or a third party. Interferon-free treatments and shorter therapy durations preferred as much as financially feasible. A separate budget is allocated to cover interferon-free treatments for the most-in-need interferon ineligible/intolerant patients, and for those who have no more interferon-based therapy option. Orv. Hetil., 2015, 156(Suppl. 2), 3-24.

[New era in the treatment of chronic hepatitis C - novel direct acting antivirals]. / Korszakváltás a krónikus C-vírus hepatitis terápiájában - új direkt ható antivirális szerek.

Chronic hepatitis C, without treatment, can cause liver cirrhosis, liver failure and liver cancer. The availability of new oral direct acting antivirals, such as the protease inhibitors simeprevir, asunaprevir and paritaprevir, the NS5A inhibitors daclatasvir, ledipasvir, and ombitasvir, the polymerase inhibitors Sofosbuvir and dasabuvir have resulted an enormous progress in the treatment of chronic hepatitis C, leading to >90% sustained viral response rates. Even the hard-to-treat or previously treatment ineligible patients can be cured with the combination of these drugs. Furthermore the treatment duration is much shorter, and the side effects are minimal. Today, treatment of all hepatitis C virus infected patients is recommended, and the best choices are the interferon-free options. Eradication of hepatitis C virus has become realistic, however, appropriate screening programs are mandatory to achieve this goal.

[Financial burden of hepatitis C infection and its treatment]. / A hepatitis C-vírus-fertozés és kezelésének költségvonzata.

The worldwide prevalence of hepatitis C infection is 2-3%. In addition to its individual consequences, it generates huge financial impact on national level. In particular, lack of recognition or late diagnosis of the disease is associated with high rate of liver cirrhosis related complications (hepatic encephalopathy, ascites, variceal bleeding, hepatocellular carcinoma) and/or demands liver transplantation. Loss of quality assisted life years and/or those spent in employment, reduced work productivity, as well as costs of antiviral therapy also contribute to the financial burden. The costs of new interferon-free therapies may exceed the prices of previous pegylated interferon based therapies with or without protease inhibitors; however, shorter treatment durations and extremely low rates of severe side-effects with much less related expenses can reduce total costs of these treatments. In addition to the moral obligations, published cost-effectiveness analyses conclude that early diagnosis and treatment of this primarily iatrogenic infection through organized screening programs and wide access to effective therapies may lead to long term financial benefit.
