Abstract
Viral hepatitis is a serious yet manageable and preventable public health menace that infects about 3 million of people and leads to 1.1 million deaths worldwide every year. An acute episode of viral hepatitis usually subsides on its own, however, if not intervened timely, chronic infection puts people at risk of cirrhosis, liver cancer, and eventually death. In 2015, the global community allied to tackle viral hepatitis, as a result of which combating viral hepatitis target was included in the sustainable development goals (SDGs), and the World Health Organisation (WHO) constituted the first-ever global health sector strategy on viral hepatitis for 2016 to 2021 which is also renewed recently. Conforming to the global commitment, India launched the National Viral Hepatitis Control Program in the year 2018 with the aim to eliminate viral hepatitis as a public health threat by the year 2030. In the Subsequent years, WHO and various other international societies have released updated recommendations with respect to vaccination, prevention of mother-to-child transmission, strategies to increase testing uptake including self-testing, newer diagnostics including point of care and reflex testing approaches, simplified treatment algorithms, expanded treatment eligibility criteria, and simplified service delivery models. With the program being in its fifth year of implementation, there is a need to revamp the operational guidelines based on various global evidence-based advancements in order to attain the ambitious elimination goal by 2030.

Abstract
BACKGROUND In Ghana, Hepatitis B virus (HBV) infection remains a major public health threat as in many parts of the world. Even with an effective vaccine, there are shortfalls with low vaccine coverage among adults. To create awareness and encourage vaccination, community engagement and public-private partnerships are needed in endemic settings to help fund campaigns and offer screening and vaccinations at no cost to under privileged people. OBJECTIVES An awareness and screening exercise was scheduled by University of Ghana-based Hepatitis-Malaria (HEPMAL) project team to coincide with the World Hepatitis Day (WHD) 2021. It was to engage the community in creating awareness of the menace and offer diagnostic services to ascertain prevalence levels and provide needed clinical support. METHODS Participants from the University of Ghana community and its immediate environs were registered, taken through pre-counselling sessions where they were educated on hepatitis transmission and prevention before consenting. Eligible participants were screened for HBV markers (HBsAg, HBeAg, HBsAb, HBcAb,HbcAg) with a rapid test kit. All HBsAb-negative participants were recommended for initial vaccination at the event, whilst the subsequent shots were administered at the University Hospital Public Health Department. Hepatitis B surface Antigen-positive participants were counselled and referred for appropriate care. RESULTS / Outcomes: A total of 297 people, comprising of 126 (42%) males and 171 (58%) females aged between 17 and 67 years were screened during the exercise. Amongst these, 246 (82.8%) showed no detectable protective antibodies against HBV and all of them agreed to and were given the first dose HBV vaccine. Additionally, 19 (6.4%) individuals tested positive for HBsAg and were counselled and referred to specialists from the University Hospital for further assessment and management. We found that 59 (19.9%) of our participants had previously initiated HBV vaccination and had taken at least one dose of the vaccine more than 6 months prior to this screening, 3 of whom tested positive for HBsAg. For the three-dose HBV vaccines deployed, a little over 20% (50/246) and a further 17% (33/196) did not return for the second and the third doses respectively, resulting in an overall 66% (163/246) of persons who completed all three vaccinations. CONCLUSIONS / Lessons learnt: Our medical campaign exercise established an active case prevalence rate of 6.4% and achieved a full vaccination success rate of 66% which is critical in the induction of long-term immunity in the participants. Aside these achievements, we would like to reiterate the importance of the use of different approaches including educational events and WHD activities to target groups and communities to raise awareness. Additionally, home and school vaccination programmes may be adopted to enhance vaccine uptake and adherence to the vaccination schedule. We plan to extend this screening exercise to deprived and/or rural communities where HBV incidence may be higher than in urban communities.

Abstract
INTRODUCTION Hepatitis E virus (HEV) is the most common cause of acute hepatitis. While symptoms are generally mild and resolve within weeks, some populations (e.g., pregnant women, immunocompromised adults) are at high-risk of severe HEV-related morbidity and mortality. There has not been a recent comprehensive review of contemporary HEV outbreaks, which limits the validity of current disease burden estimates. Therefore, we aimed to characterize global HEV outbreaks and describe data gaps to inform HEV outbreak prevention and response initiatives. METHODS We performed a systematic review of peer-reviewed (PubMed, Embase) and gray literature (ProMED) to identify reports of outbreaks published between 2011 and 2022. We included (1) reports with ≥ 5 cases of HEV, and/or (2) reports with 1.5 times the baseline incidence of HEV in a specific population, and (3) all reports with suspected (e.g., clinical case definition) or confirmed (e.g., ELISA or PCR test) cases if they met criterium 1 and/or 2. We describe key outbreak epidemiological, prevention and response characteristics and major data gaps. RESULTS We identified 907 records from PubMed, 468 from Embase, and 247 from ProMED. We screened 1,362 potentially relevant records after deduplication. Seventy-one reports were synthesized, representing 44 HEV outbreaks in 19 countries. The populations at risk, case fatalities, and outbreak durations were not reported in 66% of outbreak reports. No reports described using HEV vaccines. Reported intervention efforts included improving sanitation and hygiene, contact tracing/case surveillance, chlorinating boreholes, and advising residents to boil water. Commonly missing data elements included specific case definitions used, testing strategy and methods, seroprevalence, impacts of interventions, and outbreak response costs. Approximately 20% of HEV outbreaks we found were not published in the peer-reviewed literature. CONCLUSION HEV represents a significant public health problem. Unfortunately, extensive data shortages and a lack of standardized reporting make it difficult to estimate the HEV disease burden accurately and to implement effective prevention and response activities. Our study has identified major gaps to guide future studies and outbreak reporting systems. Our results support the development of standardized reporting procedures/platforms for HEV outbreaks to ensure accurate and timely data distribution, including active and passive coordinated surveillance systems, particularly among high-risk populations.

Abstract
BACKGROUND & AIMS Patient navigation interventions can improve health outcomes in underserved, low-income, and racial and ethnic minority groups, who often experience health disparities. We examined the effectiveness of patient navigation to improve linkage to hepatitis C virus (HCV) treatment receipt in a socioeconomically disadvantaged, racially diverse patient population. METHODS We performed a pre-post analysis evaluating the effectiveness of a patient navigation program among baby boomers who tested positive for HCV in a safety-net health system. The usual care group (June 2013 to May 2015) and patient navigation group (January 2016 to December 2017) were balanced using a stabilized inverse probability of treatment weighting approach. We used logistic regression analyses to evaluate associations between patient navigation and linkage to care for HCV treatment evaluation, treatment initiation, and sustained virologic response. RESULTS Among 1353 patients (62% black, 61% uninsured, 16% homeless), 769 were in the usual care group, and 584 were in the patient navigation group. The patient navigation group had significantly higher odds of linkage to care (odds ratio [OR], 3.7; 95% confidence interval [CI], 2.9-4.8) and treatment initiation (OR, 3.2; 95% CI, 2.3-4.2) within 6 months. The patient navigation group continued to have increased linkage to care (OR, 3.4; 95% CI, 2.7-4.3) and treatment initiation (OR 2.3; 95% CI, 1.7-3.0) at 12 months. However, there was no significant difference in sustained virologic response between the groups (86.9% vs 86.1%; P = .78). CONCLUSIONS Patient navigation was associated with significantly increased linkage to care and treatment initiation among patients with HCV infection. Patient navigation programs can be used to promote HCV elimination among traditionally difficult-to-reach patient populations.

Abstract
BACKGROUND Chronic hepatitis B (CHB) is highly prevalent among adults in rural China and better management of those populations is of vital importance for viral hepatitis elimination. Adult immunization has been the subject of much controversy in previous studies. This study estimates the cost-effectiveness of population-based hepatitis B screening, treatment, and immunization strategy (comprehensive strategy) in rural areas with high prevalence under the national policy of sharp-drop drug prices. METHODS We constructed a Markov model comparing 4 strategies in a 30-year horizon from the healthcare payer perspective: (1) the conventional pattern; (2) screening and treating infected (treatment); (3) screening and immunizing susceptible individuals (immunization); and (4) the comprehensive strategy. Screening intensity ranged from 50% to 100%. Outcomes were measured by costs, quality-adjusted life-years (QALYs), incremental cost-effectiveness ratios (ICERs), and clinical outcomes. RESULTS The costs for the conventional pattern, treatment strategy, immunization strategy, and comprehensive strategy were US$ 341, 351, 318, and 323, respectively. In addition, effects were 17.45, 17.57, 17.46, and 17.58 QALYs, respectively. The ICER of the comprehensive strategy was US$ 35/QALY gained at 50% screening intensity and 420 US$/QALY gained at 100%. The net monetary benefit increased with increasing screening intensity and declined after 90%, with the highest value of US$40 693. All new infections and 52.5% mortality could be avoided from 2020 to 2049 if all patients were properly treated and all susceptible individuals were immunized. The results were stable within a wide range of parameters. CONCLUSION It was cost-effective to implement the mass hepatitis B screening, treatment, and immunization strategy in areas of rural China with high prevalence, and the strategy gained the most net monetary benefit at a screening intensity of 90%. Although it was impractical to fulfill 100% coverage, efforts should be made to obtain more people screened.

Abstract
Each hepatitis virus-Hepatitis A, B, C, D, E, and G-poses a distinct scenario to the patient and clinician alike. Since the discovery of each virus, extensive knowledge regarding epidemiology, virologic properties, and the natural clinical and immunologic history of acute and chronic infections has been generated. Basic discoveries about host immunologic responses to acute and chronic viral infections, combined with virologic data, has led to vaccines to prevent Hepatitis A, B, and E and highly efficacious antivirals for Hepatitis B and C. These therapeutic breakthroughs are transforming the fields of hepatology, transplant medicine in general, and public and global health. Most notably, there is even an ambitious global effort to eliminate chronic viral hepatitis within the next decade. While attainable, there are many barriers to this goal that are being actively investigated in basic and clinical labs on the local, national, and international scales. Herein, we discuss pertinent clinical information and recent organizational guidelines for each of the individual hepatitis viruses while also synthesizing this information with the latest research to focus on exciting future directions for each virus.

Abstract
BACKGROUND & AIMS Achieving sustained virologic response (SVR) among patients with hepatitis C virus (HCV) leads to patient reported outcome (PRO) improvement. We aimed to assess the long-term post-SVR PRO trends in HCV patients with cirrhosis. METHODS Patients with HCV and cirrhosis treated in clinical trials with direct acting antiviral agents (DAAs) who achieved SVR-12 were prospectively enrolled in a long-term registry (clinicaltrials.gov #NCT02292706). PROs were collected every 24 weeks using the Short Form-36v2 (SF-36), CLDQ-HCV, and WPAI-HCV. RESULTS Pre-treatment baseline data were available for 854 cirrhotic patients who achieved SVR after DAAs. Of these, 730 had compensated (CC) and 124 had decompensated cirrhosis (DCC) before treatment- patients with DCC reported severe impairment in their PROs in comparison to CC patients (by mean -5% to -16% of a PRO range size; p < .05 for 16 out of 20 studied PROs]. After achieving SVR and registry enrollment, significant PRO improvements were noted from pre-treatment levels in 11/20 domains for those with DCC (+4% to +21%) and 19/20 PRO domains in patients with CC (+3% to +17%). Patients with baseline DCC had higher rates of hepatocellular carcinoma and mortality (P < .05). In patients with CC, the PRO gains persisted up to 168 weeks (3.5 years) of registry follow-up. In patients with DCC, the improvements lasted for at least 96 weeks but a declining trend after year 2. CONCLUSIONS Patients with HCV cirrhosis experience severe PRO impairment at baseline with sustainable improvement after SVR. Though those with DCC experience improvement, there is a decline after 2 years.

Abstract
BACKGROUND AND AIMS Interferon-alpha (IFN-α) treatment for chronic hepatitis B (CHB) virus infection is finite and leads to relatively higher functional cure rates (HBsAg loss) than nucleo(s)tide analogue (NA) therapy. Effects of pegylated (PEG)/conventional IFN-α treatment on clinical outcomes were evaluated in an ultra-long-term follow-up of CHB patients. METHODS HBeAg-positive patients treated with (PEG)IFN-α at a tertiary referral centre between 1977-2014 were included. We reviewed medical charts and consulted the municipal registry for patient information. Patients were invited for a single visit at the outpatient clinic in the case of missing follow-up data. The endpoints included serum HBeAg/HBsAg loss and incidence of clinical events, using life table methods and person-years to analyze the incidence of events. Patients were censored upon retreatment. RESULTS The study cohort included 267 patients, 67% male, 58% Caucasian, with a median age of 32 years. The median follow-up duration was 11.5 years. The 5 and 10-year cumulative incidence of HBsAg loss were 14% and 32%, respectively. Baseline factors associated with a higher rate of HBsAg loss were male sex, Caucasian race, genotype A, age ≥40 years, and cirrhosis. HBsAg loss rates did not differ significantly between those who received short-term (≤24 weeks) vs long-term (>24 weeks) therapy. Both HBeAg and HBsAg loss were significantly associated with improved clinical outcomes. Early response (HBeAg loss) was associated with more HBsAg loss and better patient outcomes. CONCLUSIONS During long-term follow-up, high rates of HBsAg loss were observed from a single (PEG)IFN-α course. Its persistent effects suggest that a role for IFN-α remains, potentially in novel combination therapies in search of a functional cure.

Abstract
Viral hepatitis represents a major public health hazard and is associated with significant global mortality. Over the last decade, there have been significant developments in the prevention and treatment of viral hepatitis. These changes have led to a situation whereby global elimination has become a realistic goal, fully endorsed by the World Health Organization (WHO). By 2030, the WHO aims to reduce viral hepatitis mortality by 65% and reduce new infections by 90% by 2030. These are ambitious targets and will only be met through a sustained programme. This will require expertise from hepatologists and virologists and the fields of public health and primary care. In this article, we review the causes of viral hepatitis, its management through prevention and treatments, and the most pressing challenges and recent advances.

Abstract
BACKGROUND & AIMS Seroclearance of hepatitis B surface antigen (HBsAg) is the desired end point of treatment for chronic hepatitis B virus (HBV) infection, according to guidelines. We performed a systematic review and meta-analysis to evaluate the strength of the association between HBsAg seroclearance and long-term clinical outcomes. METHODS We performed a systematic review of the PubMed, EMBASE, and Cochrane Library databases for articles that assessed HBsAg status and reported the incidence of hepatocellular carcinoma (HCC), liver decompensation, liver transplantation, and/or all-cause mortality during follow-up evaluation. We performed a meta-analysis of rate ratios (RR) using a random-effects model independently for each end point and for a composite end point. RESULTS We analyzed data from 28 studies, comprising a total of 188,316 patients with chronic HBV infection (treated and untreated), and 1,486,081 person-years (PY) of follow-up evaluation; 26 reported data on HCC, 7 on liver decompensation, and 13 on liver transplantation and/or death. The composite event rates were 0.19/1000 PY for the HBsAg seroclearance group and 2.45/1000 PY for the HBsAg-persistent group. Pooled RRs for the HBsAg seroclearance group were 0.28 for liver decompensation (95% CI, 0.13-0.59; P = .001), 0.30 for HCC (95% CI, 0.20-0.44; P < .001), 0.22 for liver transplantation and/or death (95% CI, 0.13-0.39; P < .001), and 0.31 for the composite end point (95% CI, 0.23-0.43; P < .001). No differences in RR estimates were observed among subgroups of different study or patient characteristics. CONCLUSIONS In a systematic review and meta-analysis, we found seroclearance of HBsAg to be associated significantly with improved patient outcomes. The results are consistent among different types of studies, in all patient subpopulations examined, and support the use of HBsAg seroclearance as a primary end point of trials of patients with chronic HBV infection.

Abstract
BACKGROUND & AIMS Hepatitis B virus (HBV) infection persists because the virus-specific immune response is dysfunctional. Therapeutic vaccines might be used to end immune tolerance to the virus in patients with chronic infection, but these have not been effective in patients so far. In patients with chronic HBV infection, high levels of virus antigens might prevent induction of HBV-specific immune responses. We investigated whether knocking down expression levels of HBV antigens in liver might increase the efficacy of HBV vaccines in mice. METHODS We performed studies with male C57BL/6 mice that persistently replicate HBV (genotype D, serotype ayw)-either from a transgene or after infection with an adeno-associated virus that transferred an overlength HBV genome-and expressed HB surface antigen at levels relevant to patients. Small hairpin or small interfering (si)RNAs against the common 3'-end of all HBV transcripts were used to knock down antigen expression in mouse hepatocytes. siRNAs were chemically stabilized and conjugated to N-acetylgalactosamine to increase liver uptake. Control mice were given either entecavir or non-HBV-specific siRNAs and vaccine components. Eight to 12 weeks later, mice were immunized twice with a mixture of adjuvanted HBV S and core antigen, followed by a modified Vaccinia virus Ankara vector to induce HBV-specific B- and T-cell responses. Serum and liver samples were collected and analyzed for HBV-specific immune responses, liver damage, and viral parameters. RESULTS In both models of HBV infection, mice that express hepatocyte-specific small hairpin RNAs or that were given subcutaneous injections of siRNAs had reduced levels of HBV antigens, HBV replication, and viremia (1-3 log10 reduction) compared to mice given control RNAs. Vaccination induced production of HBV-neutralizing antibodies and increased numbers and functionality of HBV-specific, CD8+ T cells in mice with low, but not in mice with high, levels of HBV antigen. Mice with initially high titers of HBV and knockdown of HBV antigen expression, but not mice with reduced viremia after administration of entecavir, developed polyfunctional, HBV-specific CD8+ T cells, and HBV was eliminated. CONCLUSIONS In mice with high levels of HBV replication, knockdown of HBV antigen expression along with a therapeutic vaccination strategy, but not knockdown alone, increased numbers of effector T cells and eliminated the virus. These findings indicate that high titers of virus antigens reduce the efficacy of therapeutic vaccination. Anti-HBV siRNAs and therapeutic vaccines are each being tested in clinical trials-their combination might cure chronic HBV infection.

Abstract
BACKGROUND & AIMS The benefits of highly effective therapies for chronic hepatitis B virus (HBV) or HCV infection can only be realized if infected individuals are identified and linked to care. We sought to identify gaps in awareness of diagnosis of HBV or HCV infection in a population-based sample of adults living in the United States (US). METHODS Using National Health and Nutrition Examinations Surveys data, we examined factors associated with HBV and HCV awareness. Participants surveyed from 2013 through 2016, age ≥20 years, with complete serologic analyses were included. HBV and HCV infections were defined by detection of serum HBsAg and anti-HCV, respectively. The primary outcome was awareness of infection-if participants replied "yes" to the question: "Has a doctor or other health professional ever told you that you have hepatitis B or C?" RESULTS Of 14,745 participants, 68 had HBV and 211 had HCV infection, corresponding to prevalence values of 0.7% and 1.8%, respectively. Among HBV-infected persons, 32% reported awareness, and 28% of aware persons reported treatment. Among HCV-infected persons, 49% reported awareness, 45% of aware persons were treated, and 59% of treated patients achieved a sustained virologic response. Factors associated with greater awareness in multivariable models included US citizenship, higher education, and abnormal level of alanine aminotransferase for HBV-infected participants and non-Hispanic race, income above the poverty line, not married, and history of injection drug use for HCV-infected participants. CONCLUSIONS Fewer than half of US adults with HBV or HCV infection are aware of their infection. Opportunities to increase awareness include provider education on cut-off values for abnormal level of alanine aminotransferase that should prompt screening, and expansion of existing screening interventions to under-recognized at-risk groups.

Abstract
The objective of this study was to examine Hepatitis A (HAV) and Hepatitis B (HBV) screening, and the risk of HBV reactivation during Hepatitis C (HCV) therapy with direct-acting antivirals (DAAs). A retrospective chart review was performed of patients treated with second generation DAA therapy from January 2014 to September 2016 at the Iowa City VA Healthcare System. In total 409 patients initiated HCV treatment, 308 (75%) and 241 (59%) were HAV and HBV vaccine eligible, respectively. Among those, 24 (8%) received a HAV vaccine, while only 20 (8%) received a HBV vaccine. Of these, 7 patients initiating an immunization in the clinic had record of completing the series. Further, 101 patients had a reactive Hepatitis B core Antibody indicating previous HBV infection, and 3 of these were tested for HBV reactivation during HCV therapy. Overall, the assessment found low rates of HAV and HBV vaccine administration, indicating missed opportunities for preventative care during HCV therapy. With the known risk of HBV reactivation with DAAs, the need for HAV and HBV screening is essential.

Abstract
Risk factors for hepatitis C virus (HCV) infection vary, and there were an estimated 1.75 million new cases worldwide in 2015. The World Health Organization aims for a 90% reduction in new HCV infections by 2030. An HCV vaccine would prevent transmission, regardless of risk factors, and significantly reduce the global burden of HCV-associated disease. Barriers to development include virus diversity, limited models for testing vaccines, and our incomplete understanding of protective immune responses. Although highly effective vaccines could prevent infection altogether, immune responses that increase the rate of HCV clearance and prevent chronic infection may be sufficient to reduce disease burden. Adjuvant envelope or core protein and virus-vectored nonstructural antigen vaccines have been tested in healthy volunteers who are not at risk for HCV infection; viral vectors encoding nonstructural proteins are the only vaccine strategy to be tested in at-risk individuals. Despite development challenges, a prophylactic vaccine is necessary for global control of HCV.

Abstract
BACKGROUND & AIMS We aimed to evaluate the safety and effectiveness of 12 or 24 weeks treatment with ledipasvir and sofosbuvir, with or without ribavirin, in treatment-experienced patients with hepatitis C virus (HCV) genotype 1 infection and cirrhosis in routine clinical practice. Patients were followed in a multi-center, prospective, observational cohort study (HCV-TARGET). METHODS We collected data from 667 treatment-experienced adults with chronic genotype 1 HCV infection who began treatment with ledipasvir and sofosbuvir, with or without ribavirin, from 2011 through September 15, 2016, according to the regional standards of care, at academic (n = 39) and community (n = 18) centers in the United States, Canada, Germany, and Israel. Information was collected from medical records and abstracted into a unique centralized data core. Independent monitors systematically reviewed data entries for completeness and accuracy. Demographic, clinical, adverse event, and virologic data were collected every 12 weeks during treatment and during the follow-up period. The primary efficacy endpoint was sustained virologic response, defined as a level of HCV RNA below the lower limit of quantification or undetectable at a minimum 64 days after the end of treatment (SVR12). The per-protocol population (n = 610) was restricted to patients who completed 12 or 24 weeks of treatment (±2 weeks) and had final virologic outcomes available. RESULTS The per-protocol analysis revealed that 579 patients (93.8%) achieved an SVR12, including 50/51 patients who received ledipasvir and sofosbuvir for 12 weeks (98%), 384/408 patients who received ledipasvir and sofosbuvir for 24 weeks (94.1%), 68/70 patients who received ledipasvir and sofosbuvir with ribavirin for 12 weeks (97.1%), and 57/60 patients who received ledipasvir and sofosbuvir with ribavirin for 24 weeks (95%). On multivariate analysis, neither treatment duration nor the addition of ribavirin was associated with SVR12. Compensated cirrhosis (odds ratio [OR] compared to decompensated cirrhosis, 2.41; 95% CI, 1.16-5.02), albumin ≥ 3.5 g/dL (OR, 3.15; 95% CI 1.46-6.80), or total bilirubin ≤ 1.2 mg/dL (OR 3.34; 95% CI, 1.59-7.00) were associated with SVR12. CONCLUSIONS In an analysis of safety and effectiveness data from the HCV-TARGET study, we found treatment with ledipasvir and sofosbuvir, with or without ribavirin, to be effective and well tolerated by treatment-experienced patients with genotype 1 HCV infection and compensated cirrhosis. There were no significant differences in rate of SVR12 among patients treated with ledipasvir and sofosbuvir for 12 or 24 weeks, with or without ribavirin. Patients with decompensated cirrhosis appear to benefit from the addition of ribavirin or extension of ledipasvir and sofosbuvir treatment to 24 weeks. ClinicalTrials.gov no: NCT10474811.

Abstract
BACKGROUND & AIMS Production of neutralizing antibodies against hepatitis B surface antigen (HBsAg) is dysregulated in patients with persistent hepatitis B virus (HBV) infection. We investigated mechanisms by which this immune response to the virus is disrupted and whether it can be restored to promote clearance of HBV. METHODS Immune-competent C57BL/6N and C57BL/6J, as well as mice deficient in follicular helper T cells (Tfh-cell-deficient), B cells, or Foxp3+ T-regulatory cells (Treg cell deficient), were given hydrodynamic injections of pAAV/HBV1.2 plasmids. Some mice were given injections of sorted Tfh cells, pan-B cells, Treg cells, or a blocking antibody against CTLA4. Production of antibodies against HBsAg and clearance of HBV were assessed by flow cytometry, enzyme-linked immunosorbent assay, polymerase chain reaction, and immunohistochemical analyses. We obtained blood samples from patients with HBV infection and isolated Treg cells. We measured the ability of Treg cells to suppress production of interleukin 21 (IL21) in CD4+ T cells. RESULTS Immune-competent C57BL/6N and C57BL/6J mice transfected with the plasmid encoding HBV had features of viral clearance and viral persistence observed in humans. A Tfh-cell response to HBsAg was required for clearance of HBV and was suppressed by Treg cells in mice with persistent HBV infection. Depletion of Treg cells or inhibition of Treg-cell function (with blocking antibody against CTLA4) restored the Tfh-cell response against HBsAg and clearance of HBV in mice. Impaired Tfh-cell response to HBsAg was observed in blood from patients with chronic HBV infection, responsiveness was restored by depletion of Treg cells or blocking antibody against CTLA4. CONCLUSIONS In studies of HBV-infected mice and blood from patients with chronic HBV infection, we found a Tfh-cell response to HBsAg of to be required for HBV clearance, and that this response was blocked by Treg cells. Inhibiting Treg-cell activity using neutralizing antibody against CTLA4 restored the ability of Tfh cells to clear HBV infection; this approach might be developed for treatment of patients with chronic HBV infection.

Abstract
BACKGROUND & AIMS Hepatocellular (HCC) surveillance guidelines for patients with chronic hepatitis B virus (HBV) infection are based on race- and age-specific estimates of HCC risk, derived from studies conducted in areas in which HBV is endemic. METHODS We conducted a retrospective cohort study using the national Veterans Administration data to identify patients with chronic HBV infection from 2001 through 2013. We examined the effect of race and age on HCC risk while adjusting for baseline clinical characteristics. RESULTS The study cohort had 8329 patients; 3498 patients (42.0%) were white, 3248 (39%) were African Americans, and 659 (7.9%) were Asian Pacific Islanders. The annual HCC incidence was highest in Asian Pacific Islanders (0.65%), followed by whites (0.57%) and African Americans (0.40%). After adjusting for clinical and viral factors, the risk of HCC was significantly higher in Asian Pacific Islanders compared with whites (adjusted hazard ratio [HR] = 2.04; 95% CI, 1.31-3.17). There was no difference in HCC risk between African Americans and whites (adjusted HR, 0.77; 95% CI, 0.58-1.02). HCC risk increased with age: adjusted HR was 1.97 (95% CI, 0.99-3.87) for 40-49 years; adjusted HR was 3.00 (95% CI, 1.55-5.81) for 50-59 years; and adjusted HR was 4.02 (95% CI, 2.03-7.94) for more than 60 years vs less than 40 years. Patients with cirrhosis had higher risk of HCC than patients without cirrhosis (adjusted HR = 3.69; 95% CI, 2.82-4.83). However, even among patients without cirrhosis, the annual incidence of HCC was more than 0.2% for all patients older than 40 years with high levels of alanine aminotransferase-regardless of race. CONCLUSIONS In a sample of male veterans with chronic HBV infection, risk of HCC is highest among Asian Pacific Islanders, followed by whites and African Americans. Cirrhosis increased HCC risk. Among patients without cirrhosis, male patients who are older than 40 years and have increased levels of alanine aminotransferase might benefit from HCC surveillance, regardless of race.

Abstract
BACKGROUND & AIMS Obesity, kidney disease, and diabetes are common conditions that can affect outcomes of patients with chronic hepatitis C. The authors aimed to quantify the burden of these comorbid conditions among adults with chronic hepatitis C in the United States and to estimate the risk of death among people with chronic hepatitis C and comorbidities. METHODS The authors conducted cross-sectional and prospective analyses of 13,726 participants in the third National Health and Nutrition Examination Survey (NHANES III) and 23,691 participants of NHANES 1999-2012. Serum samples were analyzed for the presence of antibodies to hepatitis C virus (anti-HCV); in samples found to be positive for anti-HCV, the authors quantified HCV RNA (viral load). Individuals with anti-HCV and detectable HCV RNA were considered to have chronic hepatitis C. Comorbidities were defined using self-reported, physical examination, and laboratory data, as available. The authors used logistic models and predictive margins to estimate the adjusted prevalence of comorbidities in patients with chronic hepatitis C. The authors used Poisson regression models to estimate adjusted mortality rates based on chronic hepatitis C status, with or without comorbidities. Cox proportional hazards regression models to estimate adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) of all-cause, cardiovascular, and cancer mortality according to chronic hepatitis C status, with and without comorbidities. RESULTS Among persons with chronic hepatitis C, the demographic-adjusted prevalence estimate of diabetes was 17.9% (95% CI, 11.2%-27.5%) and of obesity was 20.9% (95% CI, 12.4%-29.5%). Overall, 69.6% of persons with chronic hepatitis C had at least 1 major cardiometabolic comorbidity (95% CI, 62.1%-76.2%). Only 38% of adults with chronic hepatitis C reported a diagnosis of liver disease. Chronic hepatitis C was associated with a substantially increased risk of death (HR, 2.45), especially in the presence of diabetes (HR, 3.24) or chronic kidney disease (HR, 4.39). CONCLUSION In an analysis of NHANES data, the authors found that individuals with chronic hepatitis C have a high burden of major cardiometabolic comorbidities. Diabetes and chronic kidney disease, in particular, are associated with substantial excess mortality in persons with chronic hepatitis C.

Abstract
BACKGROUND AND AIMS The risk of hepatocellular cancer (HCC) after sustained virological response (SVR) with direct-acting antivirals (DAA) is unclear. Our aim was to examine the risk and determinants of HCC in patients cured with DAA. METHODS We conducted a retrospective cohort study of hepatitis C virus patients who were treated with DAA in any of the 129 Veterans Health Administration hospitals between January 1, 2015 and December 31, 2015. We calculated the annual incidence rates of HCC by SVR. We used Cox regression models to compare the risk of HCC in patients with vs those without SVR and to identify factors associated with incident HCC among patients with SVR. We reviewed a sample of HCC patients for tumor size and stage at diagnosis. RESULTS Among 22,500 patients treated with DAA (19,518 with SVR; 2982 without SVR), the mean (standard deviation) age was 61.6 (6.1) years, and 39.0% had cirrhosis. There were 271 new cases of HCC, including 183 in patients with SVR. Compared with patients without SVR, those with SVR had a significantly reduced risk of HCC (0.90 vs 3.45 HCC/100 person-years; adjusted hazard ratio, 0.28, 95% CI=0.22-0.36). Patients with cirrhosis had the highest annual incidence of HCC after SVR (1.82 vs 0.34/100 person-years in patients without cirrhosis; adjusted hazard ratio, 4.73. 95% CI, 3.34-6.68). Most (>44.8%) HCC were classified as stage I. Maximum size of the largest lesion was ≤5 cm in over 75% of cases. CONCLUSIONS Among patients treated with DAA, SVR was associated with a considerable reduction in the risk of HCC. We did not find any evidence to suggest that DAAs promote HCC. However, in patients with SVR, the absolute risk of HCC remained high in patients with established cirrhosis. These patients should be considered for ongoing HCC surveillance.

Abstract
OBJECTIVE To screen out adult patients for HBV and HCV infections visiting Khyber College of Dentistry Peshawar (KCD) for different dental treatments and to identify the associated risk factors. METHOD This cross-sectional study was conducted at Khyber College of Dentistry, Peshawar in the year 2013. A total of 1540 patients >15 years, visiting KCD for seeking different dental treatments were screened for hepatitis B & C. Informed consent was taken before blood collection and filling of a structured questionnaire. Blood samples were tested against HBsAg and anti HCV by using ICT that were further confirmed by ELISA. The data was analyzed using Epi info version 6. RESULTS A total of 1540 patients were screened during the study. Among these 36.4%(561) were males and 63.6%(979) were females. Overall prevalence of HBV and HCV was 5.12%(79). On screening, 2.14%(33) were found to be HBs Ag positive of which 2.5%(14) were males and 1.9%(19) were females. HCV was found positive in 2.98%(46) individuals having male to female ratio of 1.6% and 3.8%. Frequency of HBsAg was high in age group 56-65 year and HCV in 36-45 year group. Previous history of IV/IM injections, spouse patient of hepatitis, blood transfusion, surgical operation were found significant risk factors in the transmission of both hepatitis B and C, while previous history of dental treatment and sharing of clippers were significant risk factor in spreading hepatitis C infection only. CONCLUSIONS Overall prevalence of HCV was higher than HBV. Previous history of injections, spouse patient of hepatitis, blood transfusion, surgical operation were found significant risk factors in the transmission of both hepatitis B and C.

Abstract
Hepatitis B reactivation associated with immune-suppressive and biological therapies is emerging to be an important cause of morbidity and mortality in patients with current or prior exposure to hepatitis B virus (HBV) infection. The population at risk for HBV reactivation includes those who either currently are infected with HBV or have had past exposure to HBV. Because curative and eradicative therapy for HBV is not currently available, there is a large reservoir of individuals at risk for HBV reactivation in the general population. HBV reactivation with its potential consequences is particularly a concern when these people are exposed to either cancer chemotherapy, immunosuppressive or biologic therapies for the management of rheumatologic conditions, malignancies, inflammatory bowel disease, dermatologic conditions, or solid-organ or bone marrow transplantation. With the advent of newer and emerging forms of targeted biologic therapies, it has become important to understand the mechanisms whereby certain therapies are more prone to HBV reactivation. This review provides a comprehensive update on the current concepts, risk factors, molecular mechanisms, prevention, and management of hepatitis B reactivation. In addition, we provide recommendations for future research in this area.

Abstract
Patients with psychiatric disorders are usually more exposed to multiple somatic illnesses, including liver diseases. Specific links are established between psychiatric disorders and alcohol hepatitis, hepatitis B, and hepatitis C in the population as a whole, and specifically in drug abusers. Metabolic syndrome criteria, and associated steatosis or non-alcoholic steato-hepatitis (NASH) are frequent in patients with chronic psychiatric disorders under psychotropic drugs, and should be screened. Some psychiatric medications, such as neuroleptics, mood stabilizers, and a few antidepressants, are often associated with drug-induced liver injury (DILI). In patients with advanced chronic liver diseases, the prescription of some specific psychiatric treatments should be avoided. Psychiatric disorders can be a limiting factor in the decision-making and following up for liver transplantation.

Abstract
The inaugural World Hepatitis Summit was jointly convened by the World Health Organization (WHO) and the World Hepatitis Alliance and hosted by the Scottish Government and supported by Glasgow Caledonian University and Health Protection Scotland in September 2015. The three day event convened a broad range of stakeholders to meet and share ideas, experience and best practice in addressing the many facets of viral hepatitis prevention, diagnosis and treatment. With the next World Hepatitis Summit scheduled to take place from 1 to 3 November 2017, the World Hepatitis Alliance asked Hepatology, Medicine and Policy to commission a roundtable discussion article in order to encourage reflection on how the 2015 Summit was significant for stakeholders’ efforts and why it is important to keep the momentum going ahead of the World Hepatitis Summit 2017 and in the light of the newly adopted first-ever Global Health Sector Strategy on Viral Hepatitis.

Abstract
BACKGROUND & AIMS The incidence of hepatocellular carcinoma (HCC) increases with age, but protective antibody responses decrease with time after infants are immunized against hepatitis B virus (HBV). We investigated whether immunization of infants against HBV prevents their developing HCC as adults. We also searched for strategies to maximize the cancer-preventive effects. METHODS We collected data from 2 Taiwan HCC registry systems on 1509 patients (6-26 years old) diagnosed with HCC from 1983 through 2011. Data on history of HBV immunization and prenatal maternal levels of HBV antigens of all HCC patients born after July 1984 were retrieved from the HBV immunization data bank of the Taiwan Center for Disease Control. We collected data on birth cohort-specific populations (6-26 years old) of Taiwan using the National Household Registry System. Rates of HCC incidence per 10(5) person-years were derived by dividing the number of patients with HCC by the person-years of the general population. Relative risks (RR) for HCC were estimated by Poisson regression analysis in vaccinated vs unvaccinated birth cohorts. We stratified patients by age group to evaluate the association of birth cohorts and HCC risks. RESULTS Of the 1509 patients with HCC, 1343 were born before, and 166 were born after, the HBV vaccination program began. HCC incidence per 10(5) person-years was 0.92 in the unvaccinated cohort and 0.23 in the vaccinated birth cohorts. The RRs for HCC in patients 6-9 years old, 10-14 years old, 15-19 years old, and 20-26 years old who were vaccinated vs unvaccinated were 0.26 (95% confidence interval [CI], 0.17-0.40), 0.34 (95% CI, 0.25-0.48), 0.37 (95% CI, 0.25-0.51), and 0.42 (95% CI, 0.32-0.56), respectively. The RR for HCC in 6- to 26-year-olds was lower in the later vs the earlier cohorts (born in 1992-2005 vs 1986-1992; P < .001 and 1986-1992 vs 1984-1986; P < .002). Transmission of HBV from highly infectious mothers and incomplete immunization were associated with development of HCC. CONCLUSIONS Based on an analysis of 1509 patients with HCC in Taiwan, immunization of infants against HBV reduces their risk of developing HCC as children and young adults. Improving HBV vaccination strategies and overcoming risk factors could reduce the incidence of liver cancer.

Abstract
BACKGROUND & AIMS Follicular T-helper (Tfh) cells contribute to pathogen-specific antibody responses by providing maturation signals to B cells. In mice with viral infections, virus-specific Tfh cells expand and are required to contain the infection. However, less is known about human virus-specific Tfh cells or their functions during infection. We investigated whether virus-specific CD4+ T cells from patients with hepatitis C virus (HCV) infection had phenotypic or functional features of Tfh cells and contribute to the production of HCV-specific antibodies. METHODS We collected blood samples from patients with acute and chronic HCV infection and healthy individuals (controls). We performed MHC class II tetramer analyses, assays to detect intracellular cytokines in response to HCV exposure, and analyses to quantify HCV-specific antibodies. In addition, we collected liver tissues from patients with chronic HCV infection or nonviral liver disease to analyze markers of Tfh cells. RESULTS HCV-specific CD4+ T cells from patients with acute HCV infection expressed markers of Tfh cells and secreted interleukin 21 in response to HCV exposure. Longitudinal analyses of HCV-specific T-cell responses and antibody responses showed an association between expression of inducible T-cell co-stimulator and induction of virus-specific antibodies in patients with acute HCV infection. Markers of Tfh cells were barely detectable in the peripheral blood samples from patients with chronic HCV infection, but were detected in liver tissues. CONCLUSIONS Virus-specific Tfh cells can be detected in blood samples from patients with acute HCV infection; inducible T-cell co-stimulator expression correlates with production of HCV-specific antibodies. In patients with chronic infection, Tfh cells seem to disappear from the blood but are detectable in the liver.

Abstract
BACKGROUND & AIMS Assessment of the severity of liver fibrosis is an important step in evaluating patients with chronic liver disease and determining their prognosis. We compared liver stiffness measurements (LSMs) made by supersonic shear imaging (SSI) with those of transient elastography (TE)-XL for their ability to determine the degree of liver fibrosis in overweight or obese patients with chronic liver disease. METHODS We performed a prospective study of 258 patients with chronic hepatitis of different etiologies and a body mass index greater than 25, evaluated at the University of Miami from October 2013 to December 2014. Liver stiffness was measured using the TE-XL probe and SSI of the right and left lobes during the same clinic visit, and comparisons were made for fibrosis stage in 124 biopsy-proven patients. In addition, further analysis was performed on a subgroup of 102 chronic hepatitis C virus (HCV)-positive patients for whom biopsy data were available. RESULTS Reliable LSMs were obtained from 96.1%, 94.6%, and 72.1% of patients using the TE-XL probe, SSI of the right lobe, and SSI of the left lobe, respectively. TE-XL, SSI of the right lobe, and SSI of the left lobe detected severe fibrosis (fibrosis stages 3-4), with area under the receiver operating characteristic curve (AUROC) values of 0.955, 0.954, and 0.910, respectively, compared with results from histologic analysis for the 124 biopsy-proven patients included in the study; these values were 0.952, 0.949, and 0.917, respectively, for the 102 biopsy-proven patients with HCV infection. TE-XL, SSI of the right lobe, and SSI of the left lobe detected fibrosis stage 4 with AUROC values of 0.920, 0.930, and 0.910, respectively, compared with histologic analysis, in all 124-biopsy proven patients, and with AUROC values of 0.907, 0.914, and 0.887, respectively, in the 102 biopsy-proven patients with chronic HCV infection. CONCLUSIONS SSI and the TE-XL probe each accurately quantify liver fibrosis in overweight or obese patients with chronic liver disease, including those with HCV infection, when compared with data obtained from histologic analysis. SSI data obtained from the right lobe and the TE-XL probe can be used to evaluate fibrosis with similar accuracy.

Abstract
AIM: To investigate the safety/efficacy of Boceprevir-based triple therapy in hepatitis C virus (HCV)-G1 menopausal women who were historic relapsers, partial-responders and null-responders.
METHODS: In this single-assignment, unblinded study, we treated fifty-six menopausal women with HCV-G1, 46% F3-F4, and previous PEG-α/RBV failure (7% null, 41% non-responder, and 52% relapser) with 4 wk lead-in with PEG-IFNα2b/RBV followed by PEG-IFNα2b/RBV+Boceprevir for 32 wk, with an additional 12 wk of PEG-IFN-α-2b/RBV if patients were HCV-RNA-positive by week 8. In previous null-responders, 44 wk of triple therapy was used. The primary objective of retreatment was to verify whether a sustained virological response (SVR) (HCV RNA undetectable at 24 wk of follow-up) rate of at least 20% could be obtained. The secondary objective was the evaluation of the percent of patients with negative HCV RNA at week 4 (RVR), 8 (RVR BOC), 12 (EVR), or at the end-of-treatment (ETR) that reached SVR. To assess the relationship between SVR and clinical and biochemical parameters, multiple logistic regression analysis was used.
RESULTS: After lead-in, only two patients had RVR; HCV-RNA was unchanged in all but 62% who had ≤ 1 log10 decrease. After Boceprevir, HCV RNA became undetectable at week 8 in 32/56 (57.1%) and at week 12 in 41/56 (73.2%). Of these, 53.8% and 52.0%, respectively, achieved SVR. Overall, SVR was obtained in 25/56 (44.6%). SVR was achieved in 55% previous relapsers vs. 41% non-responders (P = 0.250), in 44% F0-F2 vs 54% F3-F4 (P = 0.488), and in 11/19 (57.9%) of patients with cirrhosis. At univariate analysis for baseline predictors of SVR, only previous response to antiviral therapy (OR = 2.662, 95%CI: 0.957-6.881, P = 0.043), was related with SVR. When considering “on treatment” factors, 1 log10 HCV RNA decline at week 4 (3.733, 95%CI: 1.676-12.658, P = 0.034) and achievement of RVR BOC (7.347, 95%CI: 2.156-25.035, P = 0.001) were significantly related with the SVR, although RVR BOC only (6.794, 95%CI: 1.596-21.644, P = 0.010) maintained significance at multivariate logistic regression analysis. Anemia and neutropenia were managed with Erythropoietin and Filgrastim supplementation, respectively. Only six patients discontinued therapy.
CONCLUSION: Boceprevir obtained high SVR response independent of previous response, RVR or baseline fibrosis or cirrhosis. RVR BOC was the only independent predictor of SVR.

Abstract
Hepatocellular death is present in almost all types of human liver disease and is used as a sensitive parameter for the detection of acute and chronic liver disease of viral, toxic, metabolic, or autoimmune origin. Clinical data and animal models suggest that hepatocyte death is the key trigger of liver disease progression, manifested by the subsequent development of inflammation, fibrosis, cirrhosis, and hepatocellular carcinoma. Modes of hepatocellular death differ substantially between liver diseases. Different modes of cell death such as apoptosis, necrosis, and necroptosis trigger specific cell death responses and promote progression of liver disease through distinct mechanisms. In this review, we first discuss molecular mechanisms by which different modes of cell death, damage-associated molecular patterns, and specific cell death responses contribute to the development of liver disease. We then review the clinical relevance of cell death, focusing on biomarkers; the contribution of cell death to drug-induced, viral, and fatty liver disease and liver cancer; and evidence for cell death pathways as therapeutic targets.

Abstract
There is a relationship between exercise and changes in immunity. So athletes are prone to different medical problems such as injuries and infections. Infection is an important medical problem which could be a reason for athletes’ absence from training. The relationship between physical activity and immune system, characteristics of different types of infections in athletes with emphasis on special clinical presentations or complications, time to return to physical activity and training and strategies to prevent development and transmission of infections in athletes or physically active people are the main topics of this review.

Abstract
MicroRNAs (miRNAs), a type of highly conserved small non-coding RNAs with an average length of 22 nucleotides, may serve as major regulators of gene expression and indispensable components of cellular gene expression networks. They have critical roles in normal biological processes and have been linked to many tumours, including hepatocellular carcinoma (HCC). HCC is the fifth most common malignancy and the third leading cause of cancer-related death worldwide. Viral hepatitis, caused by infection with hepatitis B or C viruses (HBV or HCV), can increase the risk of HCC and contributes to a significant disease burden around the world. Because of the variety of molecular alterations that may arise during the development and progression of HCC, standard of care and treatment for patients with HCC remains unsatisfactory. MiRNAs have been shown to participate in the pathogenesis of both HBV and HCV. In addition to a role in pathogenesis, miRNAs have significant clinical value in the early diagnosis of HCC since they are present in the blood and can be used as diagnostic markers and potential targets for specific systemic treatment.

Abstract
OBJECTIVE To describe drug use, sexual risks and the prevalence of blood-borne viral infections among men who inject image and performance enhancing drugs (IPEDs). DESIGN A voluntary unlinked-anonymous cross-sectional biobehavioural survey. SETTING 19 needle and syringe programmes across England and Wales. PARTICIPANTS 395 men who had injected IPEDs. RESULTS Of the participants (median age 28 years), 36% had used IPEDs for <5 years. Anabolic steroids (86%), growth hormone (32%) and human chorionic gonadotropin (16%) were most frequently injected, with 88% injecting intramuscularly and 39% subcutaneously. Two-thirds also used IPEDs orally. Recent psychoactive drug use was common (46% cocaine, 12% amphetamine), 5% had ever injected a psychoactive drug and 9% had shared injecting equipment. 'Viagra/Cialis' was used by 7%, with 89% reporting anal/vaginal sex in the preceding year (20% had 5+ female-partners, 3% male-partners) and 13% always using condoms. Overall, 1.5% had HIV, 9% had antibodies to the hepatitis B core antigen (anti-HBc) and 5% to hepatitis C (anti-HCV). In multivariate analysis, having HIV was associated with: seeking advice from a sexual health clinic; having had an injection site abscess/wound; and having male partners. After excluding those reporting male partners or injecting psychoactive drugs, 0.8% had HIV, 8% anti-HBc and 5% anti-HCV. Only 23% reported uptake of the hepatitis B vaccine, and diagnostic testing uptake was poor (31% for HIV, 22% for hepatitis C). CONCLUSIONS Previous prevalence studies had not found HIV among IPED injectors. HIV prevalence in this, the largest study of blood-borne viruses among IPED injectors, was similar to that among injectors of psychoactive drugs. Findings indicate a need for targeted interventions.

Abstract
BACKGROUND & AIMS Few studies have investigated the effects of different nucleos(t)ide analogues against hepatitis B virus (HBV) on levels of covalently closed circular DNA (cccDNA) and hepatitis B surface antigen (HBsAg) in patients. We measured the magnitude of reduction of cccDNA and HBsAg by nucleos(t)ide analogue therapy and assessed the correlation between their reductions. METHODS We recruited 124 patients who were treated with 1 of the 5 nucleos(t)ide analogues (lamivudine, adefovir, entecavir, telbivudine, or clevudine). All patients had undergone liver biopsy when treatment began (baseline) and 1 year later. The cccDNA and HBsAg levels were measured by real-time polymerase chain reaction and the Elecsys II HBsAg Assay, respectively. RESULTS After 1 year of treatment, HBV in 7 patients had become resistant to the nucleos(t)ide analogue. The remaining 117 patients had an average reduction of approximately 0.2 log10 IU/mL in HBsAg, 5 log10 IU/mL in serum level of HBV DNA, 2 log10 copies/cell in intrahepatic total HBV DNA, and 1 log10 copies/cell in cccDNA. Although 88 of 117 patients (75%) had undetectable serum levels of HBV DNA (<12 IU/mL), all had detectable levels of HBsAg, and only 5 (4%) had undetectable levels of cccDNA. On treatment with nucleos(t)ide analogues, patients with greater reductions in levels of cccDNA had greater reductions in HBsAg, but these reductions did not reach statistically significant correlations. CONCLUSIONS Although nucleos(t)ide analogues potently reduced serum levels of HBV DNA, the reduction of HBsAg and cccDNA was small. In short-term therapy, the magnitude of HBsAg reduction does not correlate with that of cccDNA reduction.

Abstract
BACKGROUND There are surprisingly a few studies that evaluate the impact of chronic viral hepatitis, which is common in HD (hemodialysis) patients, on HRQOL (health related quality of life). OBJECTIVES We conducted a study to evaluate the impact of chronic viral hepatitis on HRQOL and to compare their HRQOL with non-infected HD patients via a HRQOL questionnaire. PATIENTS AND METHODS The Iranian adapted version of the Kidney Disease Quality of Life Short Form (KDQOL-SF) version 1.3 questionnaires were filled out by the HD patients. In all HD patients, serum HBsAg, HBS Abs, and HCV Abs [enzyme-linked immunosorbant assay (ELISA)] were routinely checked every six months. Patients were considered to have chronic HBV infection if HBsAg was positive for more than six months. In all HD patients, third generation assay was used to detect HCV infection. Furthermore, serum HCV-RNA (PCR) was examined in anti-HCV-positive patients for confirmation of HCV infection. RESULTS in this cross sectional study 4101 patients from 103 dialysis units in Iran between October 2010 and August 2011 were included. Prevalence of hepatitis B and hepatitis C infection was 2.1% and 1.3% respectively. Almost all KDQOL items for viral hepatitis patients had equivalent or better scores than those without viral hepatitis. In the logistic regression after adjustment for age, sex, educational level, marital status, dialysis vintage, HBs Ag positivity and HCV Ab positivity, only age (P < 0.001) and educational level (P = 0.015) had negative impact on quality of life. CONCLUSIONS Our data show that not only general health and physical activity were preserved but also health perception may be better among HD patients with viral hepatitis.

Abstract
CONTEXT Several risk factors play the role in the development of hepatocellular carcinoma (HCC) from which chronic hepatitis B and C infections are the most important ones. DNA integration of hepatitis viruses alters the function of critical genes promoting malignant transformation of virus-infected liver cells. EVIDENCE ACQUISITION There are remarkable geographic differences in prevalence of chronic viral hepatitis and incidence of HCC. Middle Eastern countries are characterized by a moderate to high prevalence rate of chronic viral hepatitis in the population. This review discusses about epidemiologic findings of hepatitis B and C infections, and HCC, as well as focuses on Middle East countries, particularly Iran. We provide an overview about risk factors, prevention and treatment, and bring up the role of HCC induced by chronic viral hepatitis. RESULTS Vaccination against hepatitis B virus (HBV) in the early childhood is highly effective to lower infection rates, substantially. For hepatitis C, adequate hygiene when dealing with human blood and screening programs for blood donors can mainly reduce infection rates. As HCC is strongly associated with chronic viral hepatitis, prevention against the infection is crucial for preventing against HCC too. CONCLUSIONS Although prevention and treatment of chronic hepatitis B and C have improved within the last decades even in high-risk countries, effective and sustainable reduction of these infections still needs more actions.

Abstract
Occupational infection is a human disease caused by work-associated exposure to microbial agents through human and environmental contact. According to the literature, occupational infection was the third leading cause of occupational disease (861 cases, 8.0%), and health care, agricultural, forestry, and fishery workers were risk groups in Korea. In addition, most high-risk groups have not been protected by workers' compensation, which could lead to underestimation of the exact spectrum and magnitude of the problem, and may also result in a lack of development and implementation of occupational infection management. Through a review of national guidelines and documentations on prevention and control of occupational infection, a management strategy would promote adherence to worker safety regulations if it is explicit with regard to the agent and mode of infection in each of the high-risk groups.

Abstract
Occupational hepatic disorders are classified into toxic hepatitis, viral hepatitis, and chemical-induced malignancy in Korea. Toxic hepatitis cases were reported in workers who were exposed to dimethylformamide, dimethylacetamide, or trichloroethylene. Pre-placement medical examination and regular follow-up are necessary to prevent the development of toxic hepatitis. Viral hepatitis was chiefly reported among health care workers such as doctors, nurses and clinical pathology technicians who could easily be exposed to blood. Preventive measures for these groups therefore include vaccination and serum monitoring programs. Hepatic angiosarcoma caused by vinyl chloride monomer (VCM) exposure is a very well known occupational disease and it has not been officially reported in Korea yet. Some cases of hepatocellular carcinoma were legally approved for compensation as an occupational disease largely by overwork and stress, but not supported by enough scientific evidence. Effort to find the evidence of its causal relationship is needed.

Abstract
BACKGROUND AND AIMS The main purpose of treating and caring for patients with chronic viral hepatitis is to promote life satisfaction and a feeling of well-being in patients suffering from this disease. The aim of this study was to evaluate the effect of education on quality of life in patients with chronic hepatitis who were treated with Interferon alpha. METHODS This quasi-experimental study was conducted on 60 patients with viral hepatitis. The intervention included teaching them the method of self injection of Interferon alpha 2 b, giving them educational pamphlets and then following their continuing treatment with interferon. Patients were randomly assigned to two 30-patient groups. The data- gathering tool was a demographic characteristics questionnaire and the Quality of Life Questionnaire for Patients with Chronic Liver Disease (CLDQ). The educational program was done in four 45- minute sessions for the case group and their relatives. The follow-up period was 12 weeks. Quality of life in patients with chronic hepatitis was measured before initiating interferon therapy, and after the educational period. Quality of life in the two groups was compared. RESULTS The total quality of life score in the two groups before therapy did not show any significant difference (P = 0.351); while 12 weeks after education there was a significant difference between the two groups (P < 0.001) in three items including abdominal symptoms (P = 0.01), worry (P < 0.001) and emotional factors (P < 0.001). The other three items did not show a significant difference between the two groups. The total quality of life score in the case group was significantly different before and after education (P < 0.001), and improved after education. The total quality of life score in the control group did not differ significantly after 12 weeks (P = 0.143). CONCLUSIONS Planning short and simple educational programs has a significant effect on the patient's control of his/her disease and its side effects; and can improve quality of life, life satisfaction, and mechanisms of coping with treatment in patients with viral hepatitis.

Abstract
BACKGROUND AND AIMS Viral hepatitis is a serious complication among intravenous drug users (IDUs). The objectives of this study were to determine the seroprevalence of hepatitis B and C viruses (HBV and HCV), and associated risk factors among IDUs at a teaching hospital in Ahvaz, southwest Iran. METHODS Medical records of 333 IDUs hospitalized from 2002 to 2006 at Razi Hospital, which is affiliated to Ahvaz Jundishapur University of Medical Sciences, were reviewed. Cases meeting the criteria for a diagnosis of viral hepatitis infection were included in this study. Patients' characteristics, clinical and laboratory findings were extracted. Data of cases with hepatitis virus infection (HVI), called the HVI group and without HVI, called the NHVI group, were compared, using the chi-square test for qualitative variables and the t-test for quantitative variables. Differences with a P < 0.05 were considered significant. RESULTS Out of a total of 333 IDUs, 115 (34.5%), mostly male, with a mean age of 24.8±6.2 had HVI. More than 65% had a history of imprisonment. The mean duration of IDU was 4.5±1.6 years for the HVI group and 1.8±0.4 years for the NHVI group (P < 0.05). 85% of the HVI group and 45% of the NHVI group shared injection equipment (P < 0.05). 103 patients (30.9%) had HCV and 12 (3.6%) had HBV infection. There was a significant difference in age, duration of drug abuse, time spent in prison, sharing injection equipment, history of surgery, blood transfusion, packs of cigarettes per year and human immunodeficiency virus (HIV) co-infection between the two groups (P < 0.05). CONCLUSIONS HVI in IDU population is a prevalent complication, and is associated with heavy smoking (high number of packs of cigarettes per year), sharing injection equipment, long duration of drug usage, long duration of prison stay, HIV co-infection, history of surgery, blood and blood products transfusion. Older age, longer duration of IDU and imprisonment put the cases at higher risk of acquiring HCV in comparison to HBV.

Abstract
Hepatocellular carcinoma (HCC) is a major worldwide public health concern. Despite recent advances, there has been little success in improving the survival of HCC patients. Due to advances in diagnostic modalities and the increasing incidence of chronic viral hepatitis and nonalcoholic fatty liver disease (NAFLD), both of which are well known risk factors of HCC, the prevalence of HCC is increasing in developed countries and it is expected that this trend will continue in the future. In Middle Eastern countries the prevalence of this cancer is lower compared to sub-Saharan Africa and some Far East countries; however it is documented that the prevalence of this cancer in some parts of the Middle East is also increasing. In the current review, the prevalence and burden of this disease worldwide, particularly in Middle Eastern countries, and risk factors for HCC are discussed.
