[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.

[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.

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.

Screening and treatment of hepatitis C virus in prisons: 10 years of experience / A hepatitis C-vírus szurésének és kezelésének 10 éves tapasztalata a börtönökben

Introduction and objective: Two-thirds of patients with hepatitis C virus (HCV) infection are unaware of their infection in the European Union. The WHO aims to reduce the number of new cases of chronic hepatitis by 90% by 2030. The proportion of people infected with HCV in prisons can be up to ten times higher compared to the general population. This article is a summary of the results of the HCV screening carried out in the Hungarian prisons between 2007 and 2017. Method: Screening of anti-HCV antibodies has been performed on a voluntary basis followed by HCV PCR and genotyping in positive cases. After obtaining written informed consent from the patients, treatment was started. Treatments were performed under the guidance of hepatologists in collaboration with prison medical staff. Results: HCV screening programs and treatments are in place in 84% of Hungarian prisons. A total of 25 384 patients underwent anti-HCV screening. Anti-HCV positive result was detected in 6.6% and HCV PCR positivity was confirmed in 3.8% of the screened inmates. 55.2% patients from the HCV PCR positive population were put on treatment. Only 143 patients received full treatment, while 162 (42.6%) treatments were terminated prematurely, and the duration of treatment was unknown in 75 patients. Based on the results available on the 24th week after the end of treatment, sustained virologic response rate was 88%. Discussion: Education of patients and collaboration between hepatologists and prison medical staff play an important role in the successful result of treatment. Conclusion: Our experience demonstrates that the test and treat principle is feasible and effective at microeliminating HCV in prisons.

Infection disclosure in the injecting dyads of Hungarian and Lithuanian injecting drug users who self-reported being infected with hepatitis C virus or human immunodeficiency virus.

The aim of this study was to assess the prevalence and correlates of disclosure to network members of being hepatitis C virus (HCV)- or human immunodeficiency virus (HIV)-infected among injecting dyads of infected injection drug users (IDUs) in Budapest, Hungary and Vilnius, Lithuania,. Multivariate generalized estimating equations (GEE) were used to assess associations. Very strong infection disclosure norms exist in Hungary, and HCV disclosure was associated with using drugs and having sex within the dyad. Non-ethnic Russian IDUs in Lithuania were more likely to disclose HCV infection to non-Roma, emotionally close and HCV-infected network members, and to those with whom they shared cookers, filters, drug solutions or rinse water or got used syringes from, and if they had fewer non-IDU or IDU network members. Ethnic Russian Lithuanian IDUs were more likely to disclose HCV if they had higher disclosure attitude and knowledge scores, 'trusted' network members, and had lower non-injecting network density and higher injecting network density. HIV-infected Lithuanian IDUs were more likely to disclose to 'trusted' network members. Disclosure norms matched disclosure behaviour in Hungary, while disclosure in Lithuania to 'trusted' network members suggests possible stigmatization. Ongoing free and confidential HCV/HIV testing services for IDUs are needed to emphasize and strengthen disclosure norms, and to decrease stigma.

Liquid drugs and high dead space syringes may keep HIV and HCV prevalence high - a comparison of Hungary and Lithuania.

Despitevery similar political, drug policy and HIV prevention backgrounds, HIV and HCV prevalence is considerably different in Hungary (low HIV and moderate HCV prevalence) and Lithuania (high HCV and moderate HIV prevalence). Wecompared the drug use profile of Hungarian (n = 215) and Lithuanian (n = 300) injecting drug users (IDUs). Overall, compared with IDUs in Hungary, IDUs in Lithuania often injected opiates purchased in liquid form ('shirka'), used and shared 2-piece syringes (vs. 1-piece syringes) disproportionately more often, were less likely to acquire their syringes from legal sources and had significantly more experience with injected and less experience with non-injected drugs. It may not be liquid drugs per se that contribute to a higher prevalence of HCV and/or HIV, but it is probably factors associated with the injecting of liquid drugs, such as the wide-spread use and sharing of potentially contaminated 2-piece syringes acquired often from non-legal sources, and syringe-mediated drug sharing with 2-piece syringes. Scaling up substitution therapy, especially heroin replacement, combined with reducing the supply of liquid drugs may decrease the prevalence of high-risk injecting behaviours related to the injecting of liquid drugs and drug injecting-related infections among IDUs in Lithuania.

Vulnerability to drug-related infections and co-infections among injecting drug users in Budapest, Hungary.

BACKGROUND: Drug-related infectious diseases are among the major health consequences of drug use, and any existing drug-related infection may predispose injecting drug users (IDUs) to other infections. METHODS: We assessed among IDUs in Budapest, Hungary the prevalence of and vulnerability to selected drug-related infections and co-infections. The sample consisted of 186 participants recruited between October 2005 and December 2006. RESULTS: We found 0% HIV, 37% HCV, 24% HAV, and 14% past HBV infection. Infections with Herpes 1 or 2, tuberculosis, Chlamydia, syphilis, and gonorrhoea were 79%, 12%, 7%, 4%, and 0%, respectively. Co-infection with HAV/HCV was 12%, HBV/HCV 9%, HAV/HBV 7%, and HAV/HBV/HCV 4%. Those over age 30, the ethnic Roma, and the homeless were more likely to have any hepatitis and a higher number of drug-related infections. Amphetamine injectors were more likely to have a higher number of drug-related infections and those who travelled within Hungary were more likely to have any STI. However, those who worked at least part time and those who were in treatment were less likely to have drug-related infections. CONCLUSIONS: These results highlight the need of interventions in Hungary to reach and focus on marginalized (Roma or homeless) IDUs and address not only injecting and sex risk, but also hygienic living and injecting conditions. Furthermore, structural interventions to increase social integration (working or being in treatment) may improve welfare and decrease drug use and infection risk tied to drug use/injection among disadvantaged, marginalized, mostly minority populations.

HIV and selected blood-borne and sexually transmitted infections in a predominantly Roma (Gypsy) neighbourhood in Budapest, Hungary: a rapid assessment.

We assessed the prevalence of HIV and selected blood-borne and sexually transmitted infections among a convenience sample of 64 residents of Dzsumbuj, a predominantly Roma (Gypsy) neighbourhood in Budapest, Hungary. No cases of HIV were detected, while the prevalence of hepatitis B infection (anti-HBc) was 27% and syphilis prevalence was 2%. Romas (n = 50) were significantly more likely than non-Romas (n = 14) to have HAV antibodies (80% vs. 43%) and less likely to be HBV immunized (anti-HBs only; 6% vs. 29%). Current drug injectors (n = 13) were more likely than non-injectors (n = 51) to have antibodies against HAV (85% vs. 69%) and HCV (85% vs. 8%). While HIV has not been introduced in this population, risk conditions for a potentially explosive HIV epidemic are present. Health care policies should focus on expanding coverage for HAV and HBV immunizations, and access to HIV preventive services needs to be extended to marginalized, mostly minority populations, such as the Roma in Europe.

Prevalence of Anal Human Papillomavirus Infection in Hungarian Men Who Have Sex with Men.

Anal cancer is one of the leading causes of death in non-AIDS defining cancers. Most of these cancers are associated with high risk HPV infection. So far, the prevalence and the significance of anal HPV infection have not been studied in the Hungarian MSM population. The main objective of our study was to determine the prevalence and associated risk factors of HPV-infection in the Hungarian MSM community, particularly in HIV-infected MSM. Out of 109 examinations 92 samples (80 HIV-infected and 12 HIV-negative MSM) were evaluated for both cytological abnormalities and HPV genotyping PCR. Using a questionnaire all enrolled individuals were interviewed about their sexual behavior, socioeconomic factors, drug use and other known or suspected risk factors. In the HIV-infected cohort 97.5% of the examined individuals were positive for any HPV type. In this group we detected high risk (HR) HPV in 88.8%, low risk (LR) HPV in 75.0% and probably high risk (PHR) HPV in 47.5% and multiple HPV infection was absolutely common (82.5%). In the HIV-negative MSM group the incidence of HPV-infection was 58.3%. The respective rate of HR-HPV, LR-HPV and PHR-HPV genotypes were 33.3%, 58.4%, and 16.7%. In the HIV-negative group both HPV infection frequency and the prevalence of the pertinent genotypes were much lower. The Hungarian MSM population is severely infected with HPV and HR-HPV. High-risk sexual behaviors are strong predictors for acquiring HR-HPV co-infections. Our results underline the necessity of anal cancer screening and the introduction of the vaccination program in the high-risk population.

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.

Strong HIV and hepatitis disclosure norms and frequent risk behaviors among Hungarian drug injectors.

Ethnographic interviews and focus groups were conducted between May 2003 and January 2004 among injection drug users (IDUs; n=29) in Budapest, Hungary, to assess knowledge related to HIV, hepatitis B (HBV), and hepatitis C (HCV) and norms, attitudes, and behaviors. Participants perceived themselves at low risk for infection with HIV but at high risk for hepatitis through injection but not sexual exposure. They reported strong disclosure norms for HIV and hepatitis infections, while sexual and injection risk behaviors were influenced by trust about partners' self-report of infection status. Injection networks were small, with infrequent syringe sharing among a few close friends. Cookers and drug filters often were shared, and filters were reused as a backup drug supply. Most sexual relationships were monogamous, and condoms were used rarely. Although participant norms supported HIV/HBV/HCV testing, the lack of available behaviors with injection and sex partners who are close friends. Network interventions among IDUs in Hungary should build on disclosure norms and trust to reduce injection and sex risk. Testing services should be expanded and access increased so that IDUs can act on and reinforce their norms for testing.

Non-Hodgkin lymphoma and hepatitis C: where we are and what next?

The association between hepatitis C virus and certain B-cell non-Hodgkin lymphomas, such as marginal zone lymphomas, is supported by epidemiological studies. The exact pathogenetic mechanism is still unknown but both chronic antigenic stimulation and viral lymphotropism may contribute to the evolution of the malignant clone. Furthermore, the hematologic response following hepatitis C antiviral treatment suggests that the virus may have an etiologic role. Interferon and ribavirin based treatment proved to be successful in small case series of hepatitis C virus associated splenic lymphoma with villous lymphocytes, therefore, it is suggested that antiviral treatment could be an alternative to chemo-immunotherapy. In the near future new more potent direct acting antivirals will make interferon free treatments possible. It is still an open question whether these new short-course regimens are also effective in the treatment of associated lymphomas and what is the importance of the lymphoid reservoir in eliminating HCV.

Hepatic steatosis in individuals living with HIV measured by controlled attenuation parameter: a cross-sectional study.

OBJECTIVES: Available data on the prevalence of hepatic steatosis in an unselected HIV-infected population are limited. The aim of this study was to determine the prevalence of hepatic steatosis and assess the associated factors in HIV-infected individuals. PATIENTS AND METHODS: One hundred and thirty-six HIV-infected individuals were enrolled in this cross-sectional study. Patients underwent transient elastography and controlled attenuation parameter (CAP) measurements. We analyzed the associations between the CAP value and demographic, metabolic, and immunologic parameters. For the first time, in HIV-infected individuals, we used a continuous scale of CAP values to identify significant covariates of hepatic fat accumulation. As a result and compared with other methods, one of the main advantages of CAP was that the quantitative measurement of liver steatosis could be used for analysis. RESULTS: Using univariate analysis, CAP was significantly correlated with the following continuous variables: CD4 percentage (P=0.035), CD8 percentage (P=0.016), age (P<0.001), CD4/8 ratio (P=0.002), BMI (P<0.001), serum triglyceride (P<0.001), and serum cholesterol (P=0.004) levels, the length of known HIV positivity (P<0.001), and liver stiffness (P=0.041). With respect to categorical variables, a significant association was found for the presence of diabetes (P=0.006), hypertension (P<0.001), facial lipodystrophy (P=0.031), and the use of lopinavir (P=0.042). In multivariate analysis using linear regression, BMI (P<0.001), presence of diabetes (P=0.026), and hypertension (P=0.040) were identified as independent significant correlates. Darunavir therapy was associated negatively with the CAP value (P=0.032). CONCLUSION: Our findings reflect the importance of metabolic factors in hepatic steatosis. The strongest independent covariate was BMI.

The urgent need for HIV and hepatitis prevention in drug treatment programs in Hungary.

We assess HIV and hepatitis testing and counseling in drug treatment programs in Hungary, a country with low rates of HIV but high rates of hepatitis C among injection drug users. The official context of drug treatment programs is described, and using key informants from representative drug treatment programs, the practice of HIV and hepatitis testing and counseling in such programs is assessed. Although HIV testing and counseling occurs, testing and counseling for hepatitis B and C are rare, especially in outpatient settings, and sexual risk in the drug use context is ineffectively addressed by treatment programs. Drug treatment centers are not adequately addressing the need to provide either HIV or hepatitis prevention services. There is an urgent need for preventing HIV and related infections among drug users by integrating HIV and hepatitis B and C prevention with drug treatment.

[Human immunodeficiency virus-positive cases among intravenous drug users]. / Emberi immunhiányt okozó víruspozitív esetek intravénás droghasználók között.

AIM: The authors show human immunodeficiency virus positive cases among Hungarian intravenous drug users. PATIENTS/METHOD: The cases were identified by self-admittance (by the results of HIV screening), and by objective methods. The persons were studied by questionnaire on their risk behaviours (injecting and sexual behaviours). Treatment seeking (76 cases) and out-of-treatment (121 cases) groups were analysed. In the first group the self-admittance human immunodeficiency virus-status was taken into consideration, in the second group the objective human immunodeficiency virus-status was studied. RESULTS: In the treatment-seeking group three persons knew that they had been human immunodeficiency virus positive or had had Acquired Immunodeficiency Syndrome related disease. The three males were 25 year-old, homeless, and used heroine intravenously. In the out-of-treatment group one person was identified by objective test, who did not know his infection. This 20 year-old male used heroine and amphetamine intravenously, and his risk behaviour was not characteristic for intravenous drug users. CONCLUSION: In these cases the sexual transmission cannot be excluded, but it is pointed out, that the human immunodeficiency virus is present among intravenous drug users in Hungary. Taking into consideration the risk behaviours, these persons can transmit the disease through injecting and or sexual behaviours. In case of treatment seeking group, the treatment institutions (where the interviews took place) did not know the infections among their patients. According to their results, the authors call the attention to the human immunodeficiency virus infection among Hungarian intravenous drug users and they urge specific interventions for intravenous drug users.

Single DermaVir immunization: dose-dependent expansion of precursor/memory T cells against all HIV antigens in HIV-1 infected individuals.

BACKGROUND: The GIHU004 study was designed to evaluate the safety and immunogenicity of three doses of DermaVir immunization in HIV-infected subjects on fully suppressive combination antiretroviral therapy (cART). METHODOLOGY/PRINCIPAL FINDINGS: This first-in-human dose escalation study was conducted with three topical DermaVir doses targeted to epidermal Langerhans cells to express fifteen HIV antigens in draining lymph nodes: 0.1 mg DNA targeted to two, 0.4 mg and 0.8 mg DNA targeted to four lymph nodes. Particularly, in the medium dose cohort 0.1 mg DNA was targeted per draining lymph node via ∼8 million Langerhans cells located in 80 cm(2) epidermis area. The 28-days study with 48-week safety follow-up evaluated HIV-specific T cell responses against Gag p17, Gag p24 and Gag p15, Tat and Rev antigens. DermaVir-associated side effects were mild, transient and not dose-dependent. Boosting of HIV-specific effector CD4(+) and CD8(+) T cells expressing IFN-gamma and IL-2 was detected against several antigens in every subject of the medium dose cohort. The striking result was the dose-dependent expansion of HIV-specific precursor/memory T cells with high proliferation capacity. In low, medium and high dose cohorts this HIV-specific T cell population increased by 325-, 136,202 and 50,759 counts after 4 weeks, and by 3,899, 9,878 and 18,382 counts after one year, respectively, compared to baseline. CONCLUSIONS/SIGNIFICANCE: Single immunization with the DermaVir candidate therapeutic vaccine was safe and immunogenic in HIV-infected individuals. Based on the potent induction of Gag, Tat and Rev-specific memory T cells, especially in the medium dose cohort, we speculate that DermaVir boost T cell responses specific to all the 15 HIV antigens expressed from the single DNA. For durable immune reactivity repeated DermaVir immunization might be required since the frequency of DermaVir-boosted HIV-specific memory T cells decreased during the 48-week follow up. TRIAL REGISTRATION: ClinicalTrial.gov NCT00712530.

Monitoring of drug resistance in therapy-naïve HIV infected patients and detection of African HIV subtypes in Hungary.

Mutations in the HIV-1 pol gene associated with resistance to antiretroviral drugs in therapy-naïve Hungarian individuals transmitted as primary infection by their foreign sexual partners originated from African, Asian and other European countries had been analyzed. Drug resistance genotyping of HIV RT and PR genes were performed where mutations of 72 codons - among them 64 specific resistance codons representing 6 nucleoside reverse transcriptase inhibitor (NRTIs), 2 non-nucleoside reverse transcriptase inhibitor (NNRTIs) and 6 proteinase inhibitor (PRIs) drugs - had been analyzed by Truegene HIV-1 Genotyping kit and OpenGene Sequencing System. Viral variants harboring resistance mutations in the po l gene were detected in 14% of the subjects. The highest rate of resistance to a single class of inhibitors was detected towards PR inhibitors (12%), followed by NRTI (8%) and NNRTI (5%). On the contrary, 25% of viruses transmitted by homosexual activity contained mutations led to resistance to NNRT. Viruses from 11 percent of cases were resistant to 2 classes of inhibitors, and 7 percent to three classes of inhibitors. Based upon sequence data non-B subtypes and CRFs were detected in more than 71% of cases. HIV-1 C (10.7%), HIV-F1 (7.2%) and HIV-1 G (3.6%) were detected as the more frequent subtypes. Among the HIV-1 recombinant viruses CRF02_AG variants were found more frequently (28.5%) followed by CRF06_cpx (17.8%) indicating penetration of non-B subtypes and recombinant African variants into Hungary, which raises serious clinical and public health consequences.

The association of syringe type and syringe cleaning with HCV infection among IDUs in Budapest, Hungary.

We assessed whether syringe type, syringe cleaning and distributive syringe sharing were associated with self-reported and laboratory-confirmed HCV infection among Hungarian IDUs. Injecting drug users (N=215) were recruited from non-treatment settings in Budapest, Hungary between October 2005 and December 2006. Multivariate logistic regression models identified correlates of self-report of being HCV infected and testing positive for HCV. While 37% tested positive for HCV, 14% of the total (39% of those who tested positive) self-reported being HCV infected. Using any two-piece syringes was significantly associated with self-reported HCV infection, while distributive syringe sharing was not associated with self-report of being HCV infected. Engaging in receptive sharing of only one-piece syringes but always cleaning before reuse was not associated with testing HCV positive, while any receptive sharing of only one-piece syringes and not always cleaning before reuse was significantly associated with testing HCV positive. Sharing cookers and squirting drugs from one syringe into another syringe were not associated with testing HCV positive. The high percent of those HCV infected who did not know they were infected highlights the need to provide better access to confidential testing and counseling services. Counseling should emphasize secondary prevention of HCV among HCV infected IDUs. Our findings also indicate that syringe type and syringe cleaning practices may play a role in HCV transmission. Ethnographic research should identify the reasons why IDUs may use two-piece syringes and suggest means to reduce their use. Thorough cleaning of one-piece syringes when sterile syringes are unavailable may be an efficient way to reduce the risk of HCV infection.

Evaluation of a comprehensive AIDS education curriculum in Hungary--the role of good educators.

The aim of this research was to evaluate a school-based AIDS education programme in Eastern Europe. Four evaluation segments were undertaken: process and outcome evaluations of the training of AIDS educators and of the educational activities for students. While most AIDS education curricula focus on the content of the education, our findings demonstrate that other aspects--including the characteristics of those educators who appear to be most effective, the way in which education is affected by teachers' attitudes, and the cultural implications of transferring programmes from one country to another--also need to be considered, especially in international environments.
