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.

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.

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.

[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.

[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.

[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.

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.

Approximately 70 000 people are infected with hepatitis C virus in Hungary, more than half of whom are not aware of their infection. Early recognition and effective treatment of related liver injury may prevent consequent advanced liver diseases (liver cirrhosis and liver cancer) and its complications. In addition, it may increase work productivity and life expectancy of infected individual, and can prevent further viral transmission. Early recognition can substantially reduce the long term financial burden of related morbidity from socioeconomic point of view. Pegylated interferon + ribavirin dual therapy, which is available in Hungary since 2003, can kill the virus in 40-45% of previously not treated (naïve), and in 5-21% of previous treatment-failure patients.

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. For initiation of treatment as well as for on-treatment decisions accurate and timely molecular biology tests are mandatory. Staging of liver damage (fibrosis) non-invasive methods (transient elastography and biochemical methods) are acceptable to avoid concerns of patients related to liver biopsy. Professional decision for treatment is balanced against budget limitations in Hungary, and priority is given to those with urgent need using a national Priority Index system reflecting stage of liver disease as well as additional factors (activity and progression of liver disease, predictive factors and other special circumstances). All naïve patients are given a first chance with dual therapy. Those with genotype 1 infection and with on-treatment or historic failure to dual therapy are eligible to receive protease inhibitor based triple therapy provided, they reach financial cutoff eligibility based on Priority Index. Duration of therapy is usually 48 weeks in genotype 1 with a response-guided potential to reduce duration for non-cirrhotic patients. Patients with non-1 genotypes are treated with dual therapy (without protease inhibitors) for a genotype and response driven duration of 16, 24, 48, or 72 week. Careful monitoring for early recognition and management of side-effects as well as viral response and potential breakthrough during protease-inhibitor therapy are recommended.

[Organizational characteristics of treatment for chronic hepatitis in Hungary: Hepatitis Registry and Priority Index]. / A krónikus vírushepatitisek hazai ellátási rendszerének sajátosságai: Hepatitisz Regiszter és a Prioritási Index.

Hepatitis Registry was developed by the Hepatology Section of the Hungarian Gastroenterology Society with the contribution of the Foundation for Liver Patients. The main task was to register all interferon based treatments of chronic hepatitis C and B and to facilitate the preauthorization process. The registry helped to clarify the number and characteristics of hepatitis C patients waiting for triple therapy; 3000 previously failed patients are still eligible for protease inhibitor therapy, 40% of them already developed cirrhosis stage and 40% are null responders to the previous therapy. As a file is created for treatment authorization, the system counts automatically the Priority Index according to the calculation set in the guideline. Priority Index reflects the urgency of treatment. The most prominent parameter of the Index is the degree of fibrosis, but it also takes into account the progression rate, prognostic factors, and special situations.

[IL28B CC genotype: a protective factor and predictor of the response to interferon treatment in chronic hepatitis C virus infection]. / IL28B CC genotípus: védo tényezo és az interferonválasz prediktora krónikus hepatitis-C-vírus infekcióban.

INTRODUCTION: In chronic hepatitis C-virus infection the possible role of gene variants encoding cytokines has become the focus of interest. AIM: The aim of the study was to investigate the effect of IL28B polymorphisms on the outcome of chronic hepatitis C-virus genotype 1 infection in the Hungarian population. In addition, the association between IL28B genotypes and the Th1/Th2 cytokine production of activated peripheral blood monocytes and lymphocytes was evaluated. METHOD: Total of 748 chronic hepatitis C-virus genotype 1 positive patients (365 males and 383 females, aged between 18 and 82 years; mean age, 54±10 years) were enrolled, of which 420 patients were treated with pegylated interferon plus ribavirin for 24-72 weeks. Of the 420 patients, 195 patients (46.4%) achieved sustained virological response. The IL28B rs12979860 polymorphism was determined using Custom Taqman SNP Genotyping Assays (Applied Biosystems, Life Technologies, Foster, CA, USA). For cytokine studies, tumour necrosis factor-α, interleukin-2, interferon-γ, interleukin-2 and interleukin-4 production by LPS-stimulated monocytes and PMA-ionomycine activated lymphocytes were measured from the supernatant of the cells obtained from 40 hepatitis C-virus infected patients, using FACS-CBA Becton Dickinson test. The cytokine levels were compared in patients with different (CC, CT, TT) IL28B genotypes. RESULTS: The IL28B rs12979860 CC genotype occurred in lower frequency in hepatitis C-virus infected patients than in healthy controls (26.1% vs 51.4%, OR 0.333, p<0.001). Patients carried the T allele with higher frequency than controls (73.9%, vs 48.6%, OR 3.003, p<0.001). Pegylated interferon plus ribavirin treated patients with the IL28B CC genotype achieved higher sustained virological response rate than those with the CT genotype (58.6% vs 40.8%, OR 2.057, p = 0.002), and those who carried the T allele (41.8%, OR1.976, p = 0.002). LPS-induced TLR-4 activation of monocytes resulted in higher tumour necrosis factor-α production in patients with the IL28B CC genotype compared to non-CC individuals (p<0.01). Similarly, increased tumour necrosis factor-α, interleukin-2 and interferon-γ production by lymphocytes was found in the IL28B CC carriers (p<0.01) CONCLUSIONS: The IL28B CC genotype exerts protective effect against chronic hepatitis C-virus infection and may be a pretreatment predictor of sustained virological response during interferon-based antiviral therapy. The IL28B CC polymorphism is associated with increased Th1 cytokine production of activated peripheral blood monocytes and lymphocytes, which may play a role in interferon-induced rapid immune control and sustained virological response of pegylated interferon plus ribavirin treated patients.

[Hungarian consensus guideline for the diagnosis and treatment of B, C, and D viral hepatitis]. / Ajánlás a B-, a C- és a D-vírus hepatitisek diagnosztikájára és antivirális kezelésére.

More than 1% of the Hungarian population is infected with hepatitis B, C, or D viruses. Since 2006 the diagnostics and therapy of these infections are carried out in treatment centers according to national guidelines - since 2010 according to financial protocols. The consensus-based guidelines for 2012 are published in this paper. The guidelines stress 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 hepatitis B infection is pegylated interferon for 48 weeks or continuous entecavir therapy. The later must be continued for at least 6 months after hepatitis B surface antigen (HBsAg) seroconversion. Tenofovir disoproxil fumarat is not yet reimbursed by the National Health Insurance Fund. Adefovir dipivoxil is recommended mainly in combination therapy. Lamivudine is no longer a first choice; patients currently taking lamivudine must switch if 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. Treatment naive chronic hepatitis C patients should initially receive pegylated interferon and ribavirin dual combination therapy. In genotype 1 infection if response is insufficient at 4 or 12 weeks one of the two new direct acting antivirals (boceprevir or telaprevir) should be added. The length of treatment is usually 48 weeks; in cases of extended early viral response shorter courses are recommended. Previous treatment failure patients with genotype 1 infection should receive a protease inhibitor backed triple combination therapy, mostly for 48 weeks. However, relapsers without cirrhosis and with extended rapid viral response, shorter telaprevir based combination therapy is sufficient. Drug-drug interactions as well as emergence of viral resistance are of particular importance. For genotype 2 or 3 HCV infections 24 weeks, for genotype 4 infections 24, 48 or 72 weeks of pegylated interferon plus ribavirin therapy is recommended in general. The guidelines published here become protocols when published as official publications of the Hungarian Health Authority.

[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.
