Highlights•Chronic HCV prevalence and treatment rates among PWID vary widely across Europe.•HCV scale-up is required in most sites to reduce transmission.•Increasing OST/NSP coverage enhances prevention benefit.Graphical abstractAbstractBackground & AimsPrevention of hepatitis C virus (HCV) transmission people who inject drugs (PWID) critical for eliminating Europe. We estimated the impact current scaled-up with without scaling up opioid substitution therapy (OST) needle syringe programmes...

Nowadays, dried blood spots (DBS) are primarily used to obtain diagnostic access risk collectives such as intravenous drug users, who prone infections with hepatitis B virus (HBV), C (HCV), and human immunodeficiency (HIV). Before DBS analyses can be in this context, however, a comprehensive evaluation of its performance characteristics must conducted. To the best our knowledge, current study presents for first time essential data Abbott ARCHITECT system, which is currently worldwide leading...

People who inject drugs (PWID) are at increased risk of acquiring and transmitting HIV Hepatitis C (HCV) due to sharing injection paraphernalia unprotected sex. To generate seroprevalence data on HCV among PWID related behaviour, a multicentre sero- behavioural survey using respondent driven sampling (RDS) was conducted in eight German cities between 2011 2014. We also evaluated the feasibility effectiveness RDS for recruiting study cities. Eligible participation were people had injected...

Epidemiological data are crucial to monitoring progress towards the 2030 Hepatitis C Virus (HCV) elimination targets. Our aim was estimate prevalence of chronic HCV infection (cHCV) in European Union (EU)/European Economic Area (EEA) countries 2019. Multi-parameter evidence synthesis (MPES) used produce national estimates cHCV defined as: π = πrecρrec + πexρex πnonρnon; πrec, πex, and πnon represent among recent people who inject drugs (PWID), ex-PWID, non-PWID, respectively, while ρrec,...

Background The variety and limitations of current laboratory methods for estimating HIV-incidence has driven attempts to improve standardize the performance serological ‘Tests Recent HIV-Infections’ (TRI). Primary follow-up HIV-1 positive plasma samples from individuals with well-defined dates infection collected as part German Seroconverter Cohort provided specimens highly suitable use in comparing three TRIs: AWARE™ BED™ EIA Incidence test (BED-CEIA), Genetic systems HIV-1/HIV-2 Plus O...

Abstract Background In Germany, risk of hepatitis C virus (HCV) infection is highest among people who inject drugs (PWID). New injectors (NI) are particularly vulnerable for HCV-acquisition, but little known about health seeking behaviour and opportunities intervention in this group. We describe characteristics, HCV prevalence, estimated incidence awareness HCV-status NIs missed testing. Methods People had injected the last 12 months were recruited into a cross-sectional serobehavioural...

According to the definition of German Federal Statistical Office, about every fourth person living in Germany has a so-called migration background (MB), i.e., or at least one their parents was born without citizenship. However, MB been defined differently many studies. Also, summarises people different situations, making differentiated analysis health science more difficult. This article formulates recommendations for collection and migration-related, as well social structural, determinants...

Hepatitis B (HBV) and hepatitis C (HCV) viral infections are uncommon in Germany, though these have a higher prevalence among certain subpopulations, such as some first-generation migrant groups, people who inject drugs (PWID), HIV-positive men sex with (HIV+MSM). Repeated estimates of the number infected HBV HCV essential to facilitate monitoring elimination efforts by 2030. We estimated total each specific subpopulation. based our calculations on data from 2013, year that we strategically...

Blood cultures from a heroin user who died in June 2012, few hours after hospital admission, due to acute septic disease, revealed the presence of Bacillus anthracis. This report describes extended diagnosis by MALDI-TOF and real-time PCR rapid confirmation anthrax infection through reference laboratories. Physicians diagnostic laboratories were informed alerted efficiently reporting channels German public health institutions, which is essential for prevention further cases.

The HIV surveillance system in Germany is based on mandatory, anonymous notification of newly diagnosed cases by laboratories. Because the time between infection and diagnosis varies widely persons, it difficult to determine number recent among HIV.

Abstract Background People who inject drugs (PWID) are at high risk of blood-borne infections, and injection drug use contributes significantly to hepatitis C virus (HCV) transmission. The WHO has therefore set targets reducing HCV incidence prevalence among PWID increasing treatment coverage eliminate by 2030. DRUCK study (2011–2014) found low in Germany. To assess progress the elimination PWID, we conducted a cross-sectional two German federal states that piloted future monitoring. Methods...

Serological methods exist that allow differentiating between recent and long-standing infections in persons infected with HIV. During a pilot study Berlin 2005 2007 methodologies have been evaluated. In cross-sectional blood samples, demographic, laboratory, clinical behavioural data based on KABP survey were collected from patients newly diagnosed HIV infections. The BED-CEIA was used to determine recency of infection. Recent contributed 54% (CI [95%]: 45; 64) MSM 16% 0; 39) other...
