Viral Hepatitis Strategic Information to Achieve Elimination by 2030: Key Elements for HIV Program Managers

Impact of educational interventions on hepatitis B and C awareness among school students of Delhi NCR, India

BACKGROUND

Viral hepatitis, particularly B and C, is a major cause of liver cirrhosis and cancer, leading to about 1.4 million deaths annually. Alarmingly, less than 20% of those with hepatitis are aware of their status, with only 6.3% receiving treatment. School children can play a pivotal role in raising awareness and preventing the spread of infections. This intervention study focuses on understanding and enhancing the knowledge, attitudes, and practices related to Hepatitis B and C, among school children in Delhi NCR to foster dialogue and awareness.

METHODS

An intervention study was conducted in selected schools across Delhi NCR between September and October 2022 to assess baseline knowledge, attitudes, and practices related to Hepatitis B and C. Three of seven schools were randomly selected by probability sampling, representing 9-12 grade students, and 901 students participated. Following this, an educational interventional program was conducted using educational material, interactive sessions, and audiovisual aids. Post-intervention assessments were done to measure the impact on knowledge improvement.

RESULTS

The study is expected to provide insights into the current level of awareness regarding Hepatitis B and C. Furthermore, the intervention's effectiveness was analysed using the pre-formed questionnaire. The average pre-test knowledge score was 8.9 ± 3.2, while the post-test average was 15.6 ± 4.4, indicating a substantial increase of 6.7 ± 4.7 points (+ 75.2%). There was a positive correlation of 0.240 between pre and post-test scores. Attitude change before and after the session showed a positive percentage change of + 38.0% with a correlation of 0.351. The study indicated substantial improvements in knowledge about hepatitis B and C, notably regarding awareness about transmission methods and risk factors.

CONCLUSION

This interventional study seeks to bridge the knowledge gap among school children regarding Hepatitis B and C in Delhi NCR, fostering a proactive approach towards prevention, detection, and treatment. The considerable rise in awareness and favourable changes in perspectives post-intervention say that specific health education initiatives are pivotal in raising awareness and comprehension of infectious diseases, ultimately contributing to improving community health.

Detection of hepatitis viruses in suspected cases of Viral Haemorrhagic Fevers in Nigeria

There have been several Viral Hemorrhagic Fever (VHF) outbreaks in Nigeria which remains a public health concern. Despite the increasing number of suspected cases of VHF due to heightened surveillance activities and growing awareness, only a few cases are laboratory-confirmed to be VHF. Routinely, these samples are only tested for Lassa virus and Yellow fever virus with occasional testing for Dengue virus when indicated. The aetiology of the disease in these VHF suspected cases in Nigeria which are negative for Lassa, Yellow fever and Dengue viruses remains a puzzle. Since the clinical features exhibited by suspected VHF cases are like other endemic illnesses such as Hepatitis, there is a need to investigate the diversity and co-infections of hepatitis viruses as differentials and possible co-morbidity in suspected cases of VHFs in Nigeria. A total of three hundred and fifty (350) blood samples of 212 (60.6%) males and 138 (39.4%) females, aged <1-70 years with a mean age of 25 ±14.5, suspected of VHFs and tested negative for Lassa, Yellow fever and Dengue viruses were investigated for Hepatitis A, B, C and E viruses at the Centre for Human and Zoonotic Virology (CHAZVY), College of Medicine, University of Lagos (CMUL) using serologic and molecular techniques. The serologic analysis of these VHF suspected cases samples revealed that 126 (36%) were positive for at least one hepatitis virus. Individual prevalence for each of the hepatitis virus screened for showed that 37 (10.6%), 18 (5.1%) and 71 (20.3%) were positive for HBV, HCV and HEV respectively. All the samples were negative for HAV. A co-infection rate of 11.9% was also observed, with HCV/HEV co-infections being the most prevalent and the Northern region having the greatest burden of infection. The evidence of hepatitis virus infections in suspected cases of VHF was documented. Thus, their associations as co-morbidities and/or mortalities in this category of individuals require further investigations in endemic countries such as Nigeria. Therefore, the possible inclusion of screening for hepatitis viruses and other aetiologic agents that could mimic infections in suspected cases of VHFs in Nigeria should be thoroughly evaluated to guide informed policy on the diagnosis and management of these cases.

Serological profile of hepatitis B virus infection among traditional birth attendants and the attending pregnant women in Ibadan, Nigeria

Although a sizable number of pregnant women patronize Traditional Birth Attendants (TBAs) for deliveries in Nigeria, efforts to prevent or reduce the risk of HBV transmission are not targeted at the TBAs and the pregnant women patronizing them. This may be linked to the dearth of information on the serological profiles of HBV among this cohort. We, therefore, show the serological profiles of HBV among the cohort. One hundred and seventy pregnant women and 91 TBAs participated in this study between May and July 2019. Serological markers of HBV infection were assayed using ELISA. A prevalence of, 8.0% (95% CI: 5.0% - 11.5%) for HBsAg, 0.8% (95% CI: 0.0% - 1.9%) for HBeAg, 2.7% (95% CI: 0.8% - 5.0%) for HBcIgM, 26.1% (95% CI: 20.7% - 31.4%) for anti-HBs, 21.5% (95% CI: 16.5% - 25.4%) for anti-HBe and 67.0% (95% CI: 60.9% - 72.8%) for anti-HBc was found indicating a high percentage of carriers. Although 32 (12.3%) of the entire participants claimed to be fully vaccinated, serological evidence was only detected in 4 (12.5%). The high percentage of carriers and low evidence of vaccination necessitate intensified efforts to ensure that adequate interventions are made available and accessible to the TBAs and the pregnant women patronizing them (including newborn babies).

Embedding viral hepatitis into primary healthcare: results of a strategic landscape analysis in Vietnam and the Philippines

Chronic viral hepatitis is a significant public health concern in the Western Pacific, including in Vietnam and the Philippines. To accelerate progress toward meeting the 2030 elimination goals, the World Health Organization (WHO) encourages countries to adopt an integrated, people-centered health sector response to hepatitis, grounded in Primary Health Care (PHC). A review of the academic and grey literature, along with policy documents, was conducted to describe the national health system and PHC response to hepatitis B and C in Vietnam and the Philippines. Information was analyzed against the four strategic levers of the WHO Operational Framework for PHC to identify challenges and opportunities. The findings suggest that both countries have relatively robust policy frameworks, with some room for improvement. Vietnam may have stronger political commitment and funding than the Philippines, while the Philippines appears to be stronger in community engagement. Both countries share challenges and opportunities for learning to actualize viral hepatitis elimination utilizing a PHC approach.

Pharmacokinetics, Tolerability, and Safety of Glecaprevir/Pibrentasvir Co-formulated Bilayer Tablet Following Repeated Administration in Healthy Chinese Adults

Glecaprevir (GLE)/pibrentasvir (PIB) is an all-oral, interferon- and ribavirin-free, pan-genotypic fixed-dose combination regimen approved for the treatment of all major genotypes of hepatitis C virus (HCV) infection in many countries worldwide. To support clinical development in China, an open-label, single-center phase 1 study was conducted to evaluate the pharmacokinetics, safety, and tolerability of GLE/PIB in healthy Chinese adults in Mainland China. Eighteen participants received 3 tablets of coformulated GLE/PIB 100/40 mg once daily (QD) for 7 days. Following GLE/PIB 300 mg/120 mg administration, GLE and PIB reached maximum concentration in 4-5 hours with a terminal elimination half-life of 5.9 and 25 hours, respectively. Both GLE and PIB reached steady state by day 5, with no-to-minimal accumulation (≤17% higher). GLE/PIB exposures in healthy Chinese participants were similar to historical observations across phase 1 studies in healthy Western participants. GLE/PIB was safe and well-tolerated, with most adverse events being mild. These pharmacokinetics and safety data, together with existing global efficacy and safety data in healthy and HCV-infected Western participants, support the use of GLE/PIB 300 mg/120 mg QD in adult Chinese patients with chronic HCV infection.

Pathway to global elimination of hepatitis B: HBV cure is just the first step

Hepatitis B (HBV) is a major cause of global morbidity and mortality, and the leading cause of liver cancer worldwide. Significant advances have recently been made toward the development of a finite HBV treatment that achieves permanent loss of HBsAg and HBV DNA (so-called "HBV cure"), which could provide the means to eliminate HBV as a public health threat. However, the HBV cure is just one step toward achieving WHO HBV elimination targets by 2030, and much work must be done now to prepare for the successful implementation of the HBV cure. In this review, we describe the required steps to rapidly scale-up future HBV cure equitably. We present key actions required for successful HBV cure implementation, integrated within the World Health Organization (WHO) Global Health Sector Strategy (GHSS) 2022-2030 framework. Finally, we highlight what can be done now to progress toward the 2030 HBV elimination targets using available tools to ensure that we are preparing, but not waiting, for the cure.

Worldwide prevalence of hepatitis B virus and hepatitis C virus among patients with cirrhosis at country, region, and global levels: a systematic review

BACKGROUND

Empirical, updated country-level estimates on the proportion of cirrhosis attributable to viral hepatitis are required. We estimated the prevalence of hepatitis B virus (HBV) and hepatitis C virus (HCV) infection in patients with cirrhosis at country, regional, and global levels as an approximation for the fractions of cirrhosis attributable to viral hepatitis.

METHODS

In this systematic review, we searched MEDLINE, Embase, Web of Science, and Scielo between Jan 1, 1993, and Aug 1, 2021. Studies were eligible if they reported on the prevalence of both HBV and HCV infection in representative studies of at least 20 patients with cirrhosis. Studies were excluded if they used first-generation HCV assays or were from a selected population of patients with cirrhosis (eg, patients selected based on specific causes, veterans, injecting drug users). Two authors (CJA and CdM) selected and extracted aggregated data from the selected publications. Data were extracted for study recruitment period, age, sex, and cause of cirrhosis, among others. Data about heavy alcohol consumption and non-alcoholic fatty liver disease (NAFLD) were also extracted when available. Aggregated data from studies from key publications were requested from the authors of the original study if selection of patients was unclear or information on causes was missing. We estimated the country-specific prevalence of causes of cirrhosis by pooling study-level data from the same country using a random-effects model. Subsequently, we estimated the regional (WHO region and UN subregion) and global prevalence by weighting the country-specific prevalence by the number of new liver cancer cases that occurred in 2020, as estimated in GLOBOCAN. The study was registered with PROSPERO, CRD42020149323.

FINDINGS

Our database searches identified 21 338 records, and a further nine records were identified by scanning references of key publications. After excluding duplicates and assessing full-text articles for eligibility, 520 publications from 86 countries or territories (and reporting on 1 376 503 patients with cirrhosis) were included in the systematic review. The prevalence of HBV infection was lower among patients with cirrhosis in Europe, the Americas, and Oceania (UN subregional prevalence ranges 3-14%) than in Africa and Asia (8-61%). HCV infection prevalence was heterogenous, even within regions (12-83%). The combined prevalence of HBV and HCV infection exceeded 50% in most Asian and African regions. Globally, among patients with cirrhosis, 42% had HBV infection and 21% had HCV infection. The contribution of heavy alcohol use was highest in Europe (country range 16-78%), the Americas (17-52%), and Oceania (15-37%) and lowest in Asia (0-41%). Data on NAFLD were limited.

INTERPRETATION

HBV and HCV could account for almost two thirds of the global burden of cirrhosis. With the availability of effective interventions for the prevention or treatment of HBV and HCV, the data presented in this study will help to effectively allocate resources towards viral hepatitis elimination and to design interventions at the country level.

Estimating the attributable fraction of cirrhosis and hepatocellular carcinoma due to hepatitis B and C

A goal of the WHO strategy on the elimination of hepatitis as a public threat is a 65% reduction in the attributable mortality. Deaths related to hepatitis B and C infections are mostly due to decompensated cirrhosis and hepatocellular carcinoma (HCC) but accurately measuring mortality is challenging as death certificates often do not capture the underlying disease. The aim of this collaborative study between European Centre for Disease Prevention and Control (ECDC) and the European Association for the Study of the Liver (EASL) was to assess a WHO-developed protocol to support countries in implementing studies to collect data on the fraction of cirrhosis and hepatocellular carcinoma attributable to hepatitis B and C. Three sentinel sites (in Bulgaria, Norway and Portugal) collected data for patients first admitted or seen in their centres during 2016. Patients with cirrhosis or HCC were identified through patient files or healthcare databases using ICD-10 codes. The proportion of patients with cirrhosis and HCC who tested positive for HBV and HCV were calculated to estimate the aetiological fractions. After the pilot study was completed, each site was asked about the feasibility and acceptability of the protocol. A total of 1249 patients presenting with cirrhosis and/or HCC were evaluated across the three sites. The prevalence of HBV and HCV among cases of cirrhosis showed that in Norway and Portugal, HCV was responsible for about one-quarter of the cases, whereas in Bulgaria, HBV was more common. For HCC, HCV was responsible for more than one-third of cases in Norway and Portugal, while in Bulgaria HBV was more frequent as the underlying cause. Results obtained during the pilot study were comparable to published estimates obtained through statistical modelling or meta-analyses. Several challenges were reported from the sites involved in the pilot including the considerable time needed for reviewing the hospital records and extracting patient data. The pilot demonstrated the feasibility of collecting data on the prevalence of HBV and HCV infection among patients with cirrhosis and HCC in sentinel sites. This method can be used to estimate mortality attributable to HBV and HCV for elimination monitoring. Where easily implementable, sentinel studies are the best way to empower countries, get up-to date data and closely monitor the changes in the attributable fraction at a country level.

A global investment framework for the elimination of hepatitis B

BACKGROUND & AIMS

More than 292 million people are living with hepatitis B worldwide and are at risk of death from cirrhosis and liver cancer. The World Health Organization (WHO) has set global targets for the elimination of viral hepatitis as a public health threat by 2030. However, current levels of global investment in viral hepatitis elimination programmes are insufficient to achieve these goals.

METHODS

To catalyse political commitment and to encourage domestic and international financing, we used published modelling data and key stakeholder interviews to develop an investment framework to demonstrate the return on investment for viral hepatitis elimination.

RESULTS

The framework utilises a public health approach to identify evidence-based national activities that reduce viral hepatitis-related morbidity and mortality, as well as international activities and critical enablers that allow countries to achieve maximum impact on health outcomes from their investments - in the context of the WHO's 2030 viral elimination targets.

CONCLUSION

Focusing on hepatitis B, this health policy paper employs the investment framework to estimate the substantial economic benefits of investing in the elimination of hepatitis B and demonstrates how such investments could be cost saving by 2030.

LAY SUMMARY

Hepatitis B infection is a major cause of death from liver disease and liver cancer globally. To reduce deaths from hepatitis B infection, we need more people to be tested and treated for hepatitis B. In this paper, we outline a framework of activities to reduce hepatitis B-related deaths and discuss ways in which governments could pay for them.

Global hepatitis C elimination: an investment framework

WHO has set global targets for the elimination of hepatitis B and hepatitis C as a public health threat by 2030. However, investment in elimination programmes remains low. To help drive political commitment and catalyse domestic and international financing, we have developed a global investment framework for the elimination of hepatitis B and hepatitis C. The global investment framework presented in this Health Policy paper outlines national and international activities that will enable reductions in hepatitis C incidence and mortality, and identifies potential sources of funding and tools to help countries build the economic case for investing in national elimination activities. The goal of this framework is to provide a way for countries, particularly those with minimal resources, to gain the substantial economic benefit and cost savings that come from investing in hepatitis C elimination.

Burden of viral hepatitis caused by specific aetiologies in China, 1990-2016: findings from the GBD 2016

Background

The aim of this study is to quantify the burden caused by viral hepatitis in China from 1990 to 2016.

Methods

Data from the GBD 2016 study were extracted to calculate incidence, prevalence and disability-adjusted life years (DALYs). Trends in DALYs were assessed in 33 provinces/regions.

Results

From 1990 to 2016, the total incidence of hepatitis decreased by 88.5%. However, the prevalence of hepatitis (counts in thousands), increased by 37.6% from 153,856 (95% UI: 136,047-172,319) in 1990 to 211,721 (95% UI: 179,776-240,981) in 2016, with age-standardized prevalence rates changing slightly. The number and age-standardized rates of prevalence increased by 35.9 and 1.6% for hepatitis B, respectively, and by 81.8 and 30.4% for hepatitis C. Guangxi, Guangdong and Hainan had the highest age-standardized prevalence rates (≥16,500 per 100,000). Tibet, Qinghai and Gansu had the highest age-standardized DALYs rates (≥40 per 100,000). The largest absolute number of DALYs was observed in the 15–49 year age group in 2016. The highest rate of DALYs occurred in males aged 50–69 years and in females aged ≧70 years.

Conclusion

The incidence and DALYs of viral hepatitis decreased dramatically from 1990 to 2016. However, the prevalence still remains at a high level, which may result in heavy burdens in the future.

Mortality from liver diseases attributable to hepatitis B and C in the EU/EEA - descriptive analysis and estimation of 2015 baseline

Background: WHO has set target to reduce mortality attributable to hepatitis B (HBV) and hepatitis C (HCV) by 65% by 2030, with 2015 as baseline. We aimed to describe the European Union/European Economic Area (EU/EEA) baseline mortality from liver diseases, as defined by WHO Core-10 indicator through ICD-10 codes, and estimate mortality attributable to HBV and HCV.Methods: Age-standardised mortality rates per 100,000 for hepatocellular carcinoma (HCC, ICD-10 C22.0), chronic liver disease (CLD, ICD-10 K72-K75) and chronic viral hepatitis B and C (CHB/CHC, ICD-10 B18.1-B18.3) were calculated by gender, age-group and country using 2015 Eurostat data. Because aetiology fraction (AF) estimates were lacking for HCC and CLD as defined by C10, number of deaths in EU/EEA countries in 2015 from liver cancer (ICD-10 C22) and 'cirrhosis and other chronic liver diseases' (ICD-10 B18-B18.9, I85-I85.9, I98.2, K70-K70.3, K71.7, K74-K74.9, K75.2, K75.4-K76.2, K76.4-K76.9 and K77.8) were adjusted by corresponding AF estimates from Global Burden of Disease publications.Results: In 2015, there were wide variations across countries in mortality rates from HCC, CLD and CHB/CHC. A 2015 mortality baseline of 63,927 deaths attributable to HBV and HCV is proposed, that includes 55% of liver cancer and 45% of 'cirrhosis and other chronic liver diseases' deaths.Conclusions: The HBV and HCV attributable mortality in the EU/EEA is high. Greater efforts are needed to identify HBV and HCV infections at an early stage and link cases to care to reduce mortality from liver diseases. Country-specific AF estimates are needed to accurately estimate HBV, HCV associated mortality.

The hepatitis C virus in Iran: health policy, historical, ethical issues and future challenges

Background

Hepatitis C infection (HCV) can have a harmful effect on the health of people and can impose relevant healthcare costs. The World Health Organization has identified the elimination of Hepatitis C by 2030 as an important goal for all countries. This study aimed to identify the HCV-related policies in Iran.

Methods

A qualitative approach was used for this study. Data was collected through a comprehensive search of documents and interviews with different stakeholders related to the HCV program. Data was analyzed and validated using content analysis based on the policy triangle framework.

Results

Our findings highlighted that certain social and cultural issues related to stigma can impact on awareness-raising processes. It is also necessary to consider HCV directly in the context of government policies. All relevant stakeholders should be included. Continued talks and interactions need to be made between them for the active participation of all actors.

Conclusion

The findings of this study can provide useful information for improving, supporting and developing policy processes. Healthcare providers should address all aspects of the disease by 2030 in order to achieve the goal of HCV elimination. Evidence-based planning, support for up-to-date policies and resource mobilization are needed to achieve this ambitious goal.

Hepatitis B Virus: Advances in Prevention, Diagnosis, and Therapy

Currently, despite the use of a preventive vaccine for several decades as well as the use of effective and well-tolerated viral suppressive medications since 1998, approximately 250 million people remain infected with the virus that causes hepatitis B worldwide. Hepatitis C virus (HCV) and hepatitis B virus (HBV) are the leading causes of liver cancer and overall mortality globally, surpassing malaria and tuberculosis. Linkage to care is estimated to be very poor both in developing countries and in high-income countries, such as the United States, countries in Western Europe, and Japan. In the United States, by CDC estimates, only one-third of HBV-infected patients or less are aware of their infection. Some reasons for these low rates of surveillance, diagnosis, and treatment include the asymptomatic nature of chronic hepatitis B until the very late stages, a lack of curative therapy with a finite treatment duration, a complex natural history, and a lack of knowledge about the disease by both care providers and patients. In the last 5 years, more attention has been focused on the important topics of HBV screening, diagnosis of HBV infection, and appropriate linkage to care. There have also been rapid clinical developments toward a functional cure of HBV infection, with novel compounds currently being in various phases of progress. Despite this knowledge, many of the professional organizations provide guidelines focused only on specific questions related to the treatment of HBV infection. This focus leaves a gap for care providers on the other HBV-related issues, which include HBV's epidemiological profile, its natural history, how it interacts with other viral hepatitis diseases, treatments, and the areas that still need to be addressed in order to achieve HBV elimination by 2030. Thus, to fill these gaps and provide a more comprehensive and relevant document to regions worldwide, we have taken a global approach by using the findings of global experts on HBV as well as citing major guidelines and their various approaches to addressing HBV and its disease burden.

Help-Seeking Experiences of Hepatitis B Patients in Transnational Medical Care: The Solution to Health Inequality Is Social Mobility

This paper tracked hepatitis B patients from Medan, Indonesia to Penang, Malaysia under transnational medical care and has an understanding of their medical history and socioeconomic status. The condition of these patients improved as a result of good compliance with medical treatment, including lifestyle adjustment and regular medication. Under the influence of the marketization of healthcare, transnational medical patients in the social structure, based on their economic ability and socioeconomic status, may be expected to experience health inequalities. People with unhealthy medical distribution and weak socioeconomic status are easily prone to diseases due to environmental and social conditions; it is easier for such patients to delay or give up their medical treatment. After continuous tracking and increasing patient exposure to medical knowledge and self-care management opportunities, increasing awareness, screening, care, and treatment, the transmission of hepatitis B can be reduced to enable them to gain upward mobility by their capacities and thus improve their health. Social mobility is deemed the main approach to reduce social inequality. There have been limited medical clinical observations and tracking confirming this theory. This paper, which uses medical observation, confirmed that social mobility is considered as the principal key to reducing inequalities in health.

Moving towards hepatitis B elimination in Gulf Health Council states: From commitment to action

INTRODUCTION

In 2016, the World Health Assembly adopted the hepatitis B (HB) elimination strategy that aims at ending HB by 2030. In this descriptive review we provide the progress made and challenges to achieving hepatitis B elimination by 2030 in Gulf Health Cooperated (GHC) states.

METHODS

Data record from relevant online databases and reliable resources were reviewed until the end of 2017. The analysis was based on the core indicators of the WHO monitoring and evaluation framework for viral hepatitis B and the targets of the global health sector strategy by 2016‒2021.

RESULTS

The states introduced HB vaccination, including birth-dose for those under 5 years old, with global coverage of more than 95%, in order to prevent mother-to-child transmission of HBV. The prevalence of HB antigens declined in children under age 5 to less than 1%. However, the rate of vaccination among the most-at-risk populations remains suboptimal. All states have implemented safe blood transfusions and injection safety policies as well as universal laboratory-based surveillance for acute HB. However, surveillance for chronic HB and sequelae as well as estimation methods of morbidity and mortality to evaluate impact are not established. Similarly, harm reduction for people who inject drugs and testing and treatment policies and protocols for people with chronic HB are suboptimal.

CONCLUSIONS

Additional steps are required to strengthen immunisation among the most-at-risk populations, maintain high quality surveillance, use antiviral therapy to treat chronic HBV and stop unsafe injection practices for drug users. Establishing country-specific national hepatitis responses based on country priorities as well as the capacity of the home health sectors to address these needs are paramount. Achieving elimination targets will require a radical alteration in the current hepatitis response and this goal should be elevated to a higher priority in the public health arena.

Global progress on the elimination of viral hepatitis as a major public health threat: An analysis of WHO Member State responses 2017

In 2016, the World Health Assembly passed a resolution to eliminate viral hepatitis as a public health threat by 2030. We aimed to examine the status of the global viral hepatitis response.

Methods

In 2017, the World Health Organization (WHO) asked the Ministries of Health in all 194 Member States to complete a Country Profile on Viral Hepatitis policy uptake indicators, covering national plans/funding, engagement of civil society, testing guidance, access to treatment, and strategic information.

Results

Of 194 Member States, 135 (70%) responded, accounting for 87% of the global population infected with hepatitis B virus (HBV) and/or C virus (HCV). Of those responding, 84 (62%) had developed a national plan, of which, 49 (58%) had dedicated funding, and 62 (46%) had engaged with civil society; those engaged with civil society were more likely to have a funded plan than others (52% vs. 23%, p = 0.001). Guidance on testing pregnant women (for HBV) and people who inject drugs (for HCV) was available in 70% and 46% of Member States, respectively; 59% and 38% of Member States reported universal access to optimal therapies for HBV and HCV, respectively.

Conclusions

Most people living with hepatitis B and C reside in a country with a national hepatitis strategy. Governments who engaged with civil society were more advanced in their response. Member States need to finance these national strategies and ensure that those affected have access to hepatitis services as part of efforts to achieve universal health coverage.

Lay summary

The World Health Organization's goal to eliminate viral hepatitis as a public health threat by 2030 requires global action. Our results indicate that progress is being made by countries to scale-up national planning efforts; however, our results also highlight important gaps in current policies.

Comparison of prevention, screening and treatment of hepatitis C in Iran, Egypt and Georgia

Hepatitis C virus (HCV) infection represents one of the major public health challenges worldwide. HCV is a blood-borne pathogen associated with a high rate of mortality and imposes a dramatic societal and economic burden on health systems. Untreated chronic HCV infection can progress to liver cirrhosis and cancer. Lessons can be learned from countries such as Egypt and Georgia that are considered to be 'on-track' for the World Health Organization HCV elimination targets, as well as countries such as Iran that are 'working towards elimination'. This article compares HCV-related policies and strategies in Iran, Egypt and Georgia to identify programme strengths and limitations that could inform policy and decision makers in Iran. Controlling and eliminating HCV remain a serious public health challenge. The rising HCV incidence could generate a dramatic economic burden in the coming years. Therefore, Iran requires a strategic plan to fight HCV. Adequate cultural and social infrastructures are needed. Centres specifically devoted to the diagnosis and management of this infection should be used for screening and delivery of inexpensive and high-quality testing. Quick initiation of treatment should take place at lower costs to facilitate access to treatment.

The hepatitis C infection in Iran: a policy analysis of agenda-setting using Kingdon's multiple streams framework

Background

Hepatitis C virus (HCV) infection causes a large number of deaths annually worldwide. Policies play an important role in regulating healthcare agendas and prioritising of health-related issues. Understanding these priorities is very important in health. The objective of this study was to investigate HCV-related issues and their influence on agenda-setting in Iran.

Methods

A qualitative design was used. Data were collected by carrying out a review of documents and interviews. A comprehensive search was conducted to identify documents related to HCV-related policies in Iran. Semi-structured interviews were conducted with both purposive and snowball sampling of 14 interviewees related to the HCV programme in Iran, including government officials, civil society, development partnership members and academicians. Documents and interview data were analysed manually and using MAXQDA Version 10 software. Kingdon’s multiple streams framework was used to guide data analysis.

Results

The factors which influenced HCV-related agenda-setting were lack of proper information of the HCV epidemiology before the 1990s, lack of diagnostic facilities, neighbouring countries with high HCV prevalence, the stigma of HCV, high prevalence in prisoners, international evidence and high costs generated by HCV. The factors related to policy were effective treatment methods, drug production inside Iran, Iran Hepatitis Network, support outside government group elites and academicians. The factors related to political will were international influence, changes in the government and parliament support.

Conclusion

The findings of this study showed that there are various national and international factors that play a role in shaping HCV-related policies. It seems that, if HCV is put into the agenda, it can be eliminated in Iran by 2030 by supporting and implementing appropriate programmes from decision- and policy-makers.

Neural-network analysis of socio-medical data to identify predictors of undiagnosed hepatitis C virus infections in Germany (DETECT)

Background

Chronic hepatitis C virus (HCV)-infection is a slowly debilitating and potentially fatal disease with a high estimated number of undiagnosed cases. Given the major advances in the treatment, detection of unreported infections is a consequential step for eliminating hepatitis C on a population basis. The prevalence of chronic hepatitis C is, however, low in most countries making mass screening neither cost effective nor practicable.

Methods

We used a Kohonen artificial neural network (ANN) to analyze socio-medical data of 1.8 million insurants for predictors of undiagnosed HCV infections. The data had to be anonymized due to ethical requirements. The network was trained with variables obtained from a subgroup of 2544 patients with confirmed hepatitis C-virus (HCV) infections excluding variables directly linked to the diagnosis of HCV. All analyses were performed using the data mining solution “RayQ”. Training results were visualized three-dimensionally and the distributions and characteristics of the clusters were explored within the map.

Results

All 2544 patients with confirmed chronic HCV diagnoses were localized in a clearly defined cluster within the Kohonen self-organizing map. An additional 2217 patients who had not been diagnosed with hepatitis C co-localized to the same cluster, indicating socio-medical similarities and a potentially elevated risk of infection. Several factors including, age, diagnosis codes and drug prescriptions acted only in conjunction as predictors of an elevated HCV risk.

Conclusions

This ANN approach may allow for a more efficient risk adapted HCV-screening. However, further validation of the prediction model is required.

Update on global epidemiology of viral hepatitis and preventive strategies

Viral hepatitis is one of the major public health concerns around the world but until recently it has drawn little attention or funding from global health policymakers. Every year 1.4 million people die from viral hepatitis-related cirrhosis and liver cancer. However, the majority of the infected population are unaware of their condition. This population have significant obstacles to overcome such as lack of awareness, vulnerability, increased migration, disease stigma, discrimination, as well as poor health resources, conflict in policy development and program implementation. Despite implementing infection control measures over the last few decades eradication or significant disease reduction remains elusive.

Know Your Epidemic, Strengthen Your Response: Developing a New HIV Surveillance Architecture to Guide HIV Resource Allocation and Target Decisions

To guide HIV prevention and treatment activities up to 2020, we need to generate and make better use of high quality HIV surveillance data.
