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.

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.

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.

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.

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.

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.

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.

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.

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 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.

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.

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.

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.

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.

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.

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.

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.

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.

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).
