In Amsterdam, HIV prevalence has nearly halved among injecting drug users (IDU) since 1990. Hepatitis C virus (HCV) prevalence also declined; HIV and HCV incidence dropped to nearly zero. We examined possible explanations for these time trends, among which the implementation of harm reduction measures aimed at reducing the risk behaviour of IDU.

HCV Infection in HIV negative MSM
K. McFaul,A. Maghlaoui,M. Nzuruba,S. Farnworth,M. Foxton,M. Anderson,M. Nelsonand E. Devit; Journal of Viral Hepatitis, 2015, 22, 535–538

Acute hepatitis C infection is recognized in HIV-infected men who have sex with men (MSM), but the risk in HIV-negative MSM remains unclear. We evaluated a population of MSM with acute hepatitis C.


Strategies to Manage HCV Burden
E. Gane et al. Journal of Viral Hepatitis, 2015, 22, (Suppl. S1), 46–73

Increasing levels of diagnosis and treatment, in combination with improved treatment efficacy, were critical for achieving substantial reductions in disease burden. In most countries, the annual treated population had to increase several fold to achieve the largest reductions in HCV-related morbidity and mortality. This suggests that increased capacity for screening and treatment will be critical in many countries.


Surveillance of HCV in EU 2006 2012
E. F. Duffell et al. Journal of Viral Hepatitis, 2015, 22, 590–595

Data collected from 2006 to 2012 indicate a high burden of disease with great variation in reported cases between countries. Most cases occurred among young adult males, and although injecting drug use dominated across all cases, there were increasing numbers of acute cases reported among men who have sex with men


Where Next for Hepatitis B and C Surveillance
S. Z. Wiktor, Journal of Viral Hepatitis, 2015, 22, 571–573

There is a lack of quality data on the burden of disease due to these infections. One approach to informing policy makers on trends in hepatitis B and C is through case reporting of diagnosed cases. Data on these cases can identify outbreaks of hepatitis and monitor trends in acute and chronic infection.

Best Strategies for Global HCV Eradication
Liesl M. Hagan and Raymond F. Schinazi: Liver International 2013

Worldwide eradication of hepatitis C virus (HCV) is possible through a combination of prevention education, universal clinical and targeted community screening, effective linkage to care and treatment with promising new directacting antiviral drug regimens.   Increasing awareness of HCV infection through screening, improving treatment uptake and cure rates by providing linkage to care and more effective treatment, and ultimately combining education efforts with vaccination campaigns to prevent transmission and reinfection can slow and eventually stop the ‘silent epidemic’.

Can Antiviral Therapy For Hepatitis C Reduce The Prevalence of HCV Among Injecting Drug User Populations? A Modeling Analysis of its Prevention Utility:
Natasha K. Martin, Peter Vickerman, Graham R. Foster, Sharon J. Hutchinson,David J. Goldberg, Matthew Hickman: Journal of Hepatology 2011 vol. 54 j 1137–1144

Hepatitis C virus antiviral treatment is effective for individual patients but few active injecting drug users are treated. We considered the utility of antiviral treatment for primary prevention of hepatitis C. Despite the possibility of re-infection, modest rates of hepatitis C treatment among active injecting drug users could effectively reduce transmission. Evaluating and extending strategies to treat hepatitis C among active injectors are warranted.


The Changing Epidemiology of Hepatitis C Virus Infection in Europe:
Juan I. Esteban, Silvia Sauleda, Josep Quer: Journal of Hepatology 48 (2008) 148-162

The epidemic of HCV infection in Europe is continuously evolving and epidemiological parameters (prevalence, incidence, disease transmission patterns and genotype distribution) have changed substantially during the last 15 years. Hence, prevalence data from studies conducted a decade ago may not be useful to estimate the current and future burden of HCV infection and additional epidemiological studies should be conducted, as well as new preventive strategies implemented to control the silent epidemic. This review summarizes recently published data on the epidemiology of HCV infection in Europe focusing on the factors currently shaping the epidemic.

Hepatitis C Could Be Virtually Eliminated By 2030,Experts Believe:
Geoff Watts: BMJ 2014;348:g2700 doi: 10.1136/bmj.g2700 (Published 10 April 2014)

Hepatitis C may no longer be considered a serious public health concern within the next few decades if new drugs are as effective as early signs have shown and concerted action is taken to diagnose the condition in more patients so that they can be treated, experts in the field have predicted.

HCV-related Burden of Disease in Europe: a systematic assessment of incidence, prevalence, morbidity, and mortality:
Nikolai Mühlberger, Ruth Schwarzer, Beate Lettmeier, Gaby Sroczynski,Stefan Zeuzem2 and Uwe Siebert: BMC Public Health 2009

Hepatitis C virus (HCV) is a leading cause of chronic liver disease, end-stage cirrhosis, and liver cancer, but little is known about the burden of disease caused by the virus. This study summarised burden of disease data presently available for Europe, compared the data to current expert estimates, and identified areas in which better data is needed.

The Impact of Chronic Hepatitis C Virus Infection on Mortality:
Kenrad E. Nelson: The Journal of Infectious Diseases, July 2012

Lee and colleagues report the overall and cause-specific mortality among a cohort of 1095 persons with chronic hepatitis C virus (HCV) infection who were identified by community screening. The increased mortality among persons with chronic HCV infections also may be related to several underlying causes in addition to chronic liver diseases and liver cancer [12]. In countries where most HCV infections are from injection drug use, a substantial proportion (eg, from 15% to 27%) of deaths have been drug related [9]. In addition, many persons with chronic HCV acquired by injection drug use also have HIV infections, which contribute to their mortality


Impact of New Hepatitis C Treatments in Different Regions of the World:
Drs Wei Zhang & Hui-ying Rao: Gastroenterology 2014 www.gastrojournal.org, and at http:// dx.doi.org/10.1053/j.gastro.2014.03.008.

The rapid development of new antiviral drugs for HCV and the availability of interferon-free and soon ribavirin-free treatment regimens of 12 weeks duration with sustained virologic response (SVR) rates of >90% has stimulated predictions that HCV will be eradicated. This commentary discusses the impact of these new treatments in different regions of the world and the barriers to HCV eradication.

The impact of viral load suppression, genotype, race, and other factors on the risk of late-stage liver-related events in patients with hepatitis C (HCV) has been assessed previously using data from small observational cohorts or clinical trials. The primary outcomes were time to death and time to a composite of liver-related clinical events. Secondary outcomes included the components of the composite clinical outcome. Outcomes were measured using a time-to-event format and were analyzed using Cox proportional hazards models.

Mortality due to Viral Hepatitis in Global Burden of Disease Study 2010: new evidence of an urgent global public health priority demanding action
Benjamin C. Cowie, Kylie S. Carville, Jennifer H. MacLachlan: Antiviral Therapy 2013

The recently published Global Burden of Disease Study 2010 contains accurate, contemporary estimates of human morbidity and mortality, with substantial changes in the patterns of illness observed over the last two decades. One of the most significant alterations to these estimates has been the recognition that viral hepatitis is a leading cause of human mortality, with an estimated 1.29 million deaths worldwide in 2010. The global community must act to address emerging health priorities identified by GBD 2010, including the need to provide treatment and care to people living with viral hepatitis, especially in resource-poor settings.

The Negative Impact Of The War On Drugs on Public Health:
The Hidden Hepatitis C Epidemic Global Commission on Drug Policy, May 2013

In 2012 the Global Commission on Drug Policy released a report that outlined how the ‘war on drugs’ is driving the HIV epidemic among people who use drugs. The present report focuses on hepatitis C as it represents another massive and deadly epidemic for this population. It provides a brief overview of the hepatitis C virus, before exploring how the ‘war on drugs’ and repressive drug policies are failing to drive transmission down.

The Present and Future Disease Burden Of Hepatitis C Infection with Today’s Treatment Paradigm:
H. Razavi, I. Waked, et al.: Journal of Viral Hepatitis, 2014, 21, (Suppl. 1), 34–59

The disease burden of HCV is expected to increase as the infected population ages. A modeling approach was used to estimate the total number of viral infections, diagnosed, treated and new infections in 2013. In addition, the model was used to estimate the change in the total number of HCV infections, the disease progression and mortality in 2013–2030. Finally, an expert panel consensus was used to capture current treatment practices in each country. Using today’s treatment paradigm, the total number of HCV infections is projected to decline or remain flat in all countries studied.

The Present and Future Disease Burden of Hepatitis C Virus (HCV) Infection with Today’s Treatment Paradigm;
H. Razavi, et al.; Journal of Viral Hepatitis, 2014, 21, (Suppl. 1), 34–59

A modeling approach was used to estimate the total number of viremic infections, diagnosed, treated and new infections in 2013. In addition, the model was used to estimate the change in the total number of HCV infections, the disease progression and mortality in 2013–2030. Finally, expert panel consensus was used to capture current treatment practices in each country. Using today’s treatment paradigm, the total number of HCV infections is projected to decline or remain flat in all countries studied. However, in the same time period, the number of individuals with late-stage liver disease is projected to increase.

Strategies To Manage Hepatitis C Virus Disease Burden:
H. Wedemeyer,A. S. Duberg, et. al.: Journal of Viral Hepatitis, 2014, 21, (Suppl. 1), 60–89

This analysis suggests that successful diagnosis and treatment of a small proportion of patients can contribute significantly to the reduction of disease burden in the countries studied. The largest reduction in HCV related morbidity and mortality occurs when increased treatment is combined with higher efficacy therapies, generally in combination with increased diagnosis. With a treatment rate of approximately 10%, this analysis suggests it is possible to achieve elimination of HCV (defined as a >90% decline in total infections by 2030). However, for most countries presented, this will require a 3–5 fold increase in diagnosis and/or treatment. Thus, building the public health and clinical provider capacity for improved diagnosis and treatment will be critical.

Treatment as prevention and cure towards global eradication of hepatitis C virus
Liesl M. Hagan, Paul Root Wolpe, and Raymond F. Schinazi: Trends in Microbiology, December 2013, Vol. 21, #12

The availability of curative, direct-acting antiviral drugs against hepatitis C virus (HCV) sparks an ethical call for HCV eradication and provides essential tools to spearhead the effort. Challenges include increasing awareness of the chronic hepatitis C epidemic, garnering sufficient public, private, and governmental financial will to invest in the necessary resources, developing pangenotypic drug regimens for global application, and mitigating ethical concerns. To achieve these goals, stakeholders including clinicians, public health professionals, legislators, advocates, and industry can employ a variety of strategies such as increasing HCV screening, implementing treatment as prevention, and improving linkage to care, as well as developing innovative pricing and payment solutions, stimulating innovation through local drug development in high-prevalence regions, continuing vaccine development, and creating efficiencies in the marketing and distribution of educational materials and drug treatments.
