RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

INTRODUCTION: The increasing incidence and poor prognosis of hepatocellular carcinoma places huge burden on healthcare. AIM: After reviewing literature on epidemiological trends, risk factors, diagnosis and management options for hepatocellular carcinoma, the authors investigated results of treatment and survival data of patients in Northeastern Hungary. METHOD: In a retrospective study, the authors analyzed medical records of 187 patients with hepatocellular carcinoma (etiology, presence of cirrhosis, stage of the tumor, treatment and disease outcome). RESULTS: Seventy-one patients (38%) had known cirrhosis at the diagnosis of hepatocellular carcinoma, while in 52 patients (28%) the presence of cirrhosis was established at the time of the diagnosis of hepatocellular carcinoma. Fifteen patients (8%) had no cirrhosis and in 49 patients (26%) no data were available regarding cirrhosis. Etiological factors were alcohol consumption (52%), viral hepatitis (41%) and metabolic syndrome (44%). In cases of metabolic syndrome, hepatocellular carcinoma frequently occurred without cirrhosis. In 83% of the cases, the tumor was discovered in an advanced stage. Median survival time was significantly associated with tumor stage (Barcelona A stage vs. B/C vs. D: 829 vs. 387 vs. 137 days, respectively p<0.001) but not with disease etiology (virus 282 days, metabolic syndrome 335 days and alcohol 423 days, p = 0.65). CONCLUSIONS: High mortality of hepatocellular carcinoma was mainly attributed to the delayed diagnosis of the disease. Screening of patients with cirrhosis could only result in a partial improvement since in a great proportion cirrhosis was diagnosed simultaneously with the tumor. Screening of diabetic and obese patients by ultrasonography should be considered. Management of baseline liver disease is of importance in the care of hepatocellular carcinoma. Orv. Hetil., 2016, 157(45), 1793-1801.

RESUMO

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.

RESUMO

BACKGROUND & AIMS: Innate immune system dysfunction is common in advanced cirrhosis, with a central role of the monocyte/macrophage system. Monocytes and macrophages express the scavenger receptor CD163, which is regulated by inflammatory mediators. Cleavage of the receptor leads to the formation of soluble (s)CD163 that represents an anti-inflammatory response. We aimed to study the clinical importance of sCD163 in cirrhosis. METHODS: Sera of 378 patients were assayed for sCD163 by ELISA [193 outpatients and 185 patients with acute decompensation (AD)]. A 5-year follow-up observational study was conducted to assess the possible association between sCD163 level and poor disease outcomes. RESULTS: sCD163 level was associated with disease severity, but not with the presence of varices or prior variceal bleeding. In outpatients, sCD163 level did not predict the development of disease-specific complications or the long-term mortality. In patients with AD episode, sCD163 level was significantly higher compared to outpatients but only in the presence of bacterial infection (INF) (AD-INF:4586, AD-NON-INF:3792 and outpatients: 3538 ng/ml, P < 0.015 and P = 0.001, respectively). sCD163 level gradually increased according to severity of infection. During bacterial infections, high sCD163 level (>7000 ng/ml) was associated with increased mortality rate (42% vs. 17%, P < 0.001) and was identified as an independent predictor of 28-day mortality (hazard ratio:2.96, 95% confidence intervals:1.27-6.95) in multivariate Cox-regression model comprising aetiology, co-morbidity, model for end-stage liver disease score and leucocyte count as covariates. CONCLUSIONS: High sCD163 level is useful to identify patients with high-risk of death during an AD episode complicated by bacterial infection. This finding serves as an additional hint towards the significance of anti-inflammatory response during bacterial infection.

RESUMO

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.

RESUMO

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. Addition of two direct acting first generation protease inhibitor drugs (boceprevir and telaprevir) to the dual therapy increased the chance of sustained clearance of virus to 63-75% and 59-66%, respectively. These two protease inhibitor drugs are available and financed for a segment of Hungarian patients since May 2013. 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.

RESUMO

Diagnosis and treatment of hepatitis B and D virus infections mean that the patient is able to maintain working capacity, increase quality of life, prevent cancer, and 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 for 2014, which is agreed on a consensus meeting of specialists involved in the treatment of the above diseases. The prevalence of hepatitis B virus infection in the Hungarian general population is 0.5-0.7%. The indications of treatment is 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 cost-effective approach the guideline emphasizes 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 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. 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.

RESUMO

PURPOSE: Advanced liver fibrosis is a negative predictor of virologic response in genotype 1 chronic hepatitis C (CHC) patients. Biopsy, however, is invasive, costly, and carries some risk of complications. METHODS: Using data from the prospective, international cohort study PROPHESYS, we assessed two alternative noninvasive measures of fibrosis, the FIB-4 and AST-to-platelet ratio index (APRI), to predict virologic response in CHC patients. RESULTS: CHC genotype 1, monoinfected, treatment-naive patients prescribed peginterferon alfa-2a (40 KD)/ribavirin in accordance with country-specific legal and regulatory requirements and who had baseline METAVIR, FIB-4, and APRI scores (N = 1,592) were included in this analysis. Patients were stratified according to the baseline METAVIR, FIB-4, or APRI score to assess virologic response [hepatitis C virus (HCV) RNA <50 IU/mL] by week 4 of treatment (rapid virologic response) and 24 weeks after untreated follow-up ]sustained virologic response (SVR)]. Baseline predictors of SVR were explored by multiple logistic regression, and the strength of the association between each fibrosis measure and SVR was evaluated. Both FIB-4 and APRI scores increased with increasing levels of biopsy-assessed fibrosis. The association between FIB-4 and SVR (p < 0.1 × 10(-30)) was stronger than that between METAVIR (p = 3.86 × 10(-13)) or APRI (p = 5.48 × 10(-6)) and SVR. Baseline factors significantly associated with SVR included male gender, lower HCV RNA, lower FIB-4 score, no steatosis, and higher alanine aminotransferase ratio. CONCLUSION: The FIB-4 index provides a valuable, noninvasive measure of fibrosis and can be used to predict virologic response in patients treated with peginterferon alfa-2a (40  KD)/ribavirin.

RESUMO

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.

RESUMO

BACKGROUND & AIMS: Anti-neutrophil cytoplasmic antibodies (ANCA) are a non-uniform family of antibodies recognizing diverse components of neutrophil granulocytes. ANCA formation might be induced by protracted bacterial infections or probably reflect an abnormal immune response to commensal microorganisms. Bacterial infections are common complications in cirrhosis with high incidence of episodes caused by enteric organisms, therefore, we sought to study the presence and clinical importance of ANCA in cirrhosis. METHODS: Sera of 385 patients with cirrhosis of different etiologies were assayed for ANCA of IgG, IgA, IgA1, IgA2, and secretory IgA subtypes by indirect immunofluorescence and ELISAs. The control group comprised 202 patients with chronic liver diseases without cirrhosis and 100 healthy subjects. In cirrhosis, a 2-year follow-up, observational study was conducted to assess a possible association between the presence of ANCA and clinically significant bacterial infections. RESULTS: Prevalence of ANCA IgA was significantly higher in cirrhosis (52.2%) compared to chronic liver diseases (18.6%) or healthy controls (0%, p<0.001 for both). ANCA IgA subtyping assays revealed marked increase in the proportion of IgA2 subtype (46% of total ANCA IgA) and presence of the secretory component concurrently. Presence of ANCA IgA was associated with disease-specific clinical characteristics (Child-Pugh stage and presence of ascites, p<0.001). During a 2-year follow-up period, risk of infections was higher among patients with ANCA IgA compared to those without (41.8% vs. 23.4%, p<0.001). ANCA IgA positivity was associated with a shorter time to the first infectious complication (pLogRank <0.001) in Kaplan-Meier analysis and was identified as an independent predictor in multivariate Cox-regression analysis (HR:1.74, 95% CI: 1.18-2.56, p=0.006). CONCLUSIONS: Presence of IgA type ANCA is common in cirrhosis. Involvement of gut mucosal immune system is in center of their formation and probably reflects sustained exposure to bacterial constituents.

RESUMO

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.

RESUMO

Chronic B and C virus hepatitis (HBV and HCV) are the most important risk factors in the development of hepatocellular carcinoma (HCC). About 40-50% of HCC is induced by these two chronic viral infections. Prevalence of HCC is slowly increasing in the United States and in Western-Europe, whereas alcohol consumption is gradually decreasing in the majority of these countries. However, the most important environmental risk factor for HCC is still the heavy long-term alcohol use. The risk of cirrhosis and HCC increases linearly, wherever ethanol intake is greater than 60 g/day for men and women. Aflatoxin, which contaminates grains, mostly in China and Africa, is a well-known mycotoxin. Since geographical distribution of aflatoxin as well as HBV overlaps with each other, they have a synergistic effect on inducing HCC. Cigarette smoking has also hepatocarcinogenic effect, which is significantly enhanced by the concomitant alcohol use or chronic viral hepatitis. Obesity, non-alcoholic fatty liver and steatohepatitis as well as diabetes mellitus together also form a significant risk for HCC, due to the gradually increasing number of patients. Insulin resistance and oxidative stress are the major pathogenetic mechanisms leading to hepatic cell injury in these patients. Oral contraceptive drugs may also play a role in the development of HCC. The long-term exposure to organic solvents is also a risk factor for HCC. Dietary antioxidants, selenium, statins and coffee drinking have protective effect against HCC.
