Viral hepatitis is a major public health threat and a leading cause of death worldwide. Annual mortality from viral hepatitis is similar to that of other major infectious diseases such as HIV and tuberculosis. Highly effective prevention measures and treatments have made the global elimination of viral hepatitis a realistic goal, endorsed by all WHO member states. Ambitious targets call for a global reduction in hepatitis-related mortality of 65% and a 90% reduction in new infections by 2030. This Commission draws together a wide range of expertise to appraise the current global situation and to identify priorities globally, regionally, and nationally needed to accelerate progress. We identify 20 heavily burdened countries that account for over 75% of the global burden of viral hepatitis. Key recommendations include a greater focus on national progress towards elimination with support given, if necessary, through innovative financing measures to ensure elimination programmes are fully funded by 2020. In addition to further measures to improve access to vaccination and treatment, greater attention needs to be paid to access to affordable, high-quality diagnostics if testing is to reach the levels needed to achieve elimination goals. Simplified, decentralised models of care removing requirements for specialised prescribing will be required to reach those in need, together with sustained efforts to tackle stigma and discrimination. We identify key examples of the progress that has already been made in many countries throughout the world, demonstrating that sustained and coordinated efforts can be successful in achieving the WHO elimination goals.

INTRODUCTION
Transmissible blood-borne infections are a serious threat to blood transfusion safety in West African countries; and yet blood remains a key therapeutic product in the clinical management of patients. Sierra Leone screens blood donors for blood-borne infections but has not implemented prevention of mother-to-child transmission for hepatitis B. This study aimed to describe the overall prevalence of hepatitis B and C, HIV and syphilis among blood donors in Sierra Leone in 2016 and to compare the differences between volunteer versus family replacement donors, as well as urban versus rural donors.
METHODS
Retrospective, cross-sectional study from January-December 2016 in five blood bank laboratories across the country. Routinely-collected programme data were analyzed; blood donors were tested with rapid diagnostic tests-HBsAg for HBV, anti-HCV antibody for HCV, antibodies HIV1&2 for HIV and TPHA for syphilis.
RESULTS
There were 16807 blood samples analysed, with 80% from males; 2285 (13.6%) tested positive for at least one of the four pathogens. Overall prevalence was: 9.7% hepatitis B; 1.0% hepatitis C; 2.8% HIV; 0.8% syphilis. Prevalence was higher among samples from rural blood banks, the difference most marked for hepatitis C. The proportion of voluntary donors was 12%. Family replacement donors had a higher prevalence of hepatitis B, C and HIV than volunteers.
CONCLUSION
A high prevalence of blood-borne pathogens, particularly hepatitis B, was revealed in Sierra Leone blood donors. The study suggests the country should implement the prevention of mother-to-child transmission of hepatitis B and push to recruit more volunteer, non-remunerated blood donors.

Treatment experiences with patients co-infected with human immunodeficiency virus (HIV) and hepatitis B virus (HBV) in resource-limited settings remain poorly documented. This study aimed to evaluate the treatment outcomes in a cohort of HIV/HBV co-infected individuals receiving tenofovir/lamivudine (TDF/3TC)-based antiretroviral therapy (ART) in a programmatic setting in Mumbai, India. Additionally, a cross-sectional laboratory study was carried out measuring serologic and virologic parameters. A total of 57 patients who received TDF/3TC were included in the study. Of these, 52 (91%) were male and the mean age was 38.7 years. The median follow-up period was 16.8 months (IQR:7.9-37.9). Forty-three patients were included in the cross-sectional laboratory study, of whom 38 (67%) were HBeAg(+) positive. Four patients had serum HBsAg conversion to negative and had developed anti-HBs-antibodies. HBV-DNA became undetectable (<1.3 log10 copies/ml or <20 IU/ml) in 35.5% and 75% of the HBeAg(+) and HBeAg(-) patients, respectively. Overall, 46.5% of patients had undetectable HBV-DNA and 90.7% had adequately suppressed HBV-DNA (<3.3 log10 copies/ml or <2000 IU/ml). The median reduction in serum HBV-DNA was 6 log10 copies/ml. In 29 patients (63%) HIV viral load was undetectable. Outcomes included seven (12%) deaths, four (7%) lost to follow-up, one (2%) transferred out and 45 (79%) alive and on treatment. In conclusion, good treatment outcomes were achieved in a cohort of HIV/HBV co-infected patients in India. In regions with a high HIV/HBV burden, all HIV-infected individuals should be tested for chronic hepatitis B. A TDF/3TC-backbone could be considered as first-line standardized ART regimen in these settings.

Successful treatment outcomes for chronic hepatitis B virus (HBV) infection requires high levels of adherence to treatment. We searched three databases and abstracts from two conferences up to January 2018 for studies reporting the proportion of patients who were adherent to HBV antiviral therapy and pooled data using random effects meta-analysis. We included 30 studies, providing data for 23,823 patients. Overall, adherence to treatment was 74.6% (95% confidence interval [CI] 67.1%-82.1%). Adherence was similar in high-income settings (75.1%; 95% CI, 65.4%-85.0%) and in low-income and middle-income settings (72.9%; 95% CI, 57.8%-88.0%). Reported barriers to adherence included forgetting, limited understanding of the importance of adherence, and change to routine.
CONCLUSION
There is a need to reinforce assessment and reporting of adherence as a routine part of HBV care and to assess the extent to which evidence-based interventions to improve adherence to medication for human immunodeficiency virus [HIV] and other chronic diseases are effective for HBV infection.

OBJECTIVE
To pilot an intervention on the prevention of mother-to-child transmission (PMTCT) of hepatitis B virus (HBV) in an antenatal care and maternity unit in Maputo, Mozambique, during 2017-2019.
METHODS
We included HBV in the existing screening programme (for human immunodeficiency virus (HIV) and syphilis) for pregnant women at their first consultation, and followed mother-child dyads until 9 months after delivery. We referred women who tested positive for hepatitis B surface antigen (HBsAg) for further tests, including hepatitis B e antigen (HBeAg) and HBV viral load. According to the results, we proposed tenofovir for their own health or for PMTCT. We administered birth-dose HBV vaccine and assessed infant HBV status at 9 months.
FINDINGS
Of 6775 screened women, 270 (4.0%) were HBsAg positive; in those for whom data were available, 24/265 (9.1%) were HBeAg positive and 14/267 (5.2%) had a viral load of > 200 000 IU/mL. Ninety-eight (36.3%) HBsAg-positive women were HIV coinfected, 97 of whom were receiving antiretroviral treatment with tenofovir. Among HIV-negative women, four had an indication for tenofovir treatment and four for tenofovir PMTCT. Of 217 exposed liveborn babies, 181 (83.4%) received birth-dose HBV vaccine, 160 (88.4%) of these < 24 hours after birth. At the 9-month follow-up, only one out of the 134 tested infants was HBV positive.
CONCLUSION
Our nurse-led intervention highlights the feasibility of integrating PMTCT of HBV into existing antenatal care departments, essential for the implementation of the triple elimination initiative. Universal birth-dose vaccination is key to achieving HBV elimination.

Hepatitis B vaccination (HBV) is recommended for high-risk groups, such as people who inject drugs (PWIDs). As part of a harm reduction program by a non-governmental organization, hepatitis B screening, vaccination and antibody (HBAb) testing after completion of the vaccination schedule were offered to PWIDS in Myanmar. We determined the proportions of HBV non-completion and sero-unprotection among PWIDs enrolled in the program and their association with socio-demographic and clinical characteristics. We conducted a descriptive study based on routine program data in five selected clinics in Hpakant Township, Myanmar. PWIDs who were Hepatitis B antigen negative at screening during January 2015-December 2018 were included. Among 5386 participants eligible for HBV, 9% refused vaccination. Among those who accepted vaccination (n = 3177 individuals), 65% completed vaccination. Of those tested for HBsAb (n = 2202), 30% were sero-unprotected. Young-adults (aged 18-44 years) and migrant workers had a higher risk of incomplete vaccination. However, participants who used methadone had a lower risk of incomplete vaccination. Migrant workers had higher risk of not returning for HBsAb testing and HIV-positive participants had a higher risk of being HBV sero-unprotected. Efforts to increase HBV vaccination in PWIDs for young adults and clients during methadone and anti-retroviral services should be prioritized.

SETTING
Two free-standing urban human immunodeficiency virus (HIV) testing and counselling (HCT) centres in Bhutan offering services to the general population and targeting the most at-risk populations (MARPs).
OBJECTIVES
To assess the trend in testing for HIV, hepatitis B and syphilis in both the general population and MARPs, and to determine if sociodemographic and risk behaviour characteristics are associated with HIV, hepatitis B and syphilis seropositivity.
DESIGN
Cross-sectional study using client records, 2009–2012.
RESULTS
Of 7894 clients, 3009 (38%) were from the general population, while 4885 (62%) were from MARPs. Over the 4-year period, testing declined progressively among the general population, while it increased or remained static for MARPs. Of 4885 MARPs, seropositivity was respectively 0.7%, 1.3% and 1.2% for HIV, hepatitis B and syphilis. Female sex workers (FSWs) (relative risk[RR] 4.4, P=0.03) and partners of person living with HIV(RR 25.9, P<0.001) had a higher risk of being HIV-positive. FSWs had also a greater risk of being syphilis-positive(RR 9.1, P<0.001).
CONCLUSION
The increase in uptake of HCT services by MARPs is a welcome finding; however, the relatively static trends call for the introduction of community outreach approaches. The critical gateway being provided to MARPs is an ‘opportunity’ for the expansion of the current service package.
