    Approximately 2.5% of the Malaysian population is currently living with hepatitis C virus (HCV) infection. Yet, the public awareness of the disease is limited and under-screening remains a major challenge. With the support of international non-for-profit organizations, the Ministry of Health in Malaysia recently launched a one-week nationwide hepatitis C screening campaign in conjunction with the World Hepatitis Day. For the first time, the rapid diagnostic test (RDT) for HCV screening was introduced in public health institutions. This campaign involved 49 hospitals and 38 health clinics across the country, targeting the adult general population with unknown HCV infection status. Of the 11 382 participants undergoing the RDT, 1.9% were found to be positive for hepatitis C antibody (anti-HCV) and were referred to on-site medical departments or nearby hospitals for confirmatory testing and treatment. Men, the Malay ethnic group, intranasal and injection drug users and ex-prisoners were shown to have higher odds of being positive for anti-HCV. In addition to serving as a model to educate the general population about the disease, this campaign demonstrates the feasibility of decentralizing HCV screening, particularly by promoting the use of RDT, and linking the HCV-infected patients to care in Malaysia.

    BACKGROUND: Hepatitis B infection is a significant worldwide health issue, predispose to the development of liver cirrhosis and hepatocellular carcinoma. Entecavir is a potent oral antiviral agent of high genetic barrier for the treatment of chronic hepatitis B infection. Cutaneous adverse reaction associated with entecavir has rarely been reported in literature. As our knowledge, this case was the first case reported on entecavir induced lichenoid drug eruption.

    CASE PRESENTATION: 55 year old gentlemen presented with generalised pruritic erythematous rash on trunk and extremities. Six weeks prior to his consultation, antiviral agent entecavir was commenced for his chronic hepatitis B infection. Skin biopsy revealed acanthosis and focal lymphocytes with moderate perivascular lymphocyte infiltration. Skin condition recovered completely after caesation of offending drug and short course of oral corticosteroids.

    CONCLUSION: This case highlight the awareness of clinicians on the spectrum of cutaneous drug reaction related to entecavir therapy.

    The hepatitis C virus (HCV) consists of eight genotypes and 90 subtypes, with genotype (GT) 3 being the second most common globally and is linked to higher incidences of steatosis and rapid development of fibrosis and cirrhosis. The NS3/4A serine protease, a heterodimer complex of two HCV non-structural proteins, is an effective target for pharmaceutical intervention due to its essential roles in processing HCV polyproteins and inhibiting innate immunity. This study combines structure-based virtual screening (SBVS) of predefined compound libraries, pharmacokinetic prediction (ADME/T) and in vitro evaluation to identify potential low molecular weight (<500 Dalton) inhibitors of the NS3/4A serine protease (GT3). In silico screening of ZINC and PubChem libraries yielded five selected compounds as potential candidates. Dose-dependent inhibition of the NS3/4A serine protease and HCV replication in HuH-7.5 cells revealed that compound A (PubChem ID No. 16672637) exhibited inhibition towards HCV GT3 with an IC50 of 106.7µM and EC50 of 25.8µM, respectively. Thus, compound A may be developed as a potent, low molecular weight drug against the HCV NS3/4A serine protease of GT3.

    Food borne diseases like cholera, typhoid fever, hepatitis A, dysentery and food poisoning occur as the results of ingestion of foodstuffs contaminated with microorganisms or chemical. The true incidence of food borne disease in Malaysia is unknown, however the incidence is low ranging from 1.56 to 0.14 cases per 100,000 population and the food poisoning cases is on the rise as the evident by the incident rate of 62.47 cases per 100,000 population in 2008 and 36.17 in 2009. The rapid population growth and demographic shift toward ageing population, changing eating habit such as consumption of raw or lightly cooked food, long storage of such food, lack of education on basic rules of hygienic food preparation and food trading without appropriate microbiological safety procedure become contributing factors for food borne diseases. Food borne disease in Malaysia is in the rise and the direct and indirect cost management of FBD will become one of the most common issues to face by the government. The world is spending millions and millions in cost of treatment due to food borne diseases. The information on this paper was collected via findings of previous journals, data and statistics from the MOH of Malaysia and WHO websites. As a result, authors found that the prevention and management of the food borne disease outbreak needs to be addressed seriously.

    Accidental needle-stick injuries (NSIs) are a hazard for health-care workers and general public health. Orthopaedic surgeons may be more prone to NSIs due to the prevalence of bone spikes in the operative field and the use of sharp orthopaedic instruments such as drills, saws and wires. A hospital-based cross sectional study was conducted in the orthopedic wards of Melaka General Hospital. The prevalence of NSIs was 32 (20.9%) and majority of it occurred during assisting in operation theatre 13(37.4%). Among them six (18.8%) were specialist, 12(37.5%) medical officer, 10 (31.2%) house officer and four staff nurses (12.5%). Among the respondents 142 (92.8%) had been immunized against Hepatitis B and 148 (96.7%) participants had knowledge regarding universal precaution. The incidence of NSI among health care workers at orthopaedics ward was not any higher in comparison with the similar studies and it was found out that the prevalence was more in junior doctors compared with specialist and staff nurses and it was statistically significant.

    From November 1996 to December 1997, 24 infants with neonatal cholestasis were referred to the Department of Paediatrics, University of Malaya Medical Center, Kuala Lumpur for further investigations. Nineteen had neonatal hepatitis. There was considerable delay in referral of infants with cholestasis; the mean age of referral was 63.7 days. None had a positive family history of neonatal hepatitis. All infant had hepatomegaly and ten had splenomegaly. The stools were slightly pale in thirteen, persistently acholic in three and normally pigmented in three infants. Liver synthetic functions were normal in most of the infants. Cytomegalovirus (CMV) IgM antibodies were positive in seven but none were positive for toxoplasma or rubella. al - antitrypsin deficiency, hypothyroidism, and galactosaemia were excluded in all infants. DISIDA scans were performed in seventeen infants, being non-excretory in eight. Liver biopsies were performed in fifteen infants, showing neonatal hepatitis in fourteen, while histological features of large duct obstruction was seen in one. In majority of infants (eight out of ten) the jaundice disappeared by six months. Two infants had progressive jaundice and liver function impairment.

    PURPOSE OF REVIEW: To describe models of integrated and co-located care for opioid use disorder (OUD), hepatitis C (HCV), and HIV.

    RECENT FINDINGS: The design and scale-up of multidisciplinary care models that engage, retain, and treat individuals with HIV, HCV, and OUD are critical to preventing continued spread of HIV and HCV. We identified 17 models within primary care (N = 3), HIV specialty care (N = 5), opioid treatment programs (N = 6), transitional clinics (N = 2), and community-based harm reduction programs (N = 1), as well as two emerging models. Key components of such models are the provision of (1) medication-assisted treatment for OUD, (2) HIV and HCV treatment, (3) HIV pre-exposure prophylaxis, and (4) behavioral health services. Research is needed to understand differences in effectiveness between co-located and fully integrated care, combat the deleterious racial and ethnic legacies of the "War on Drugs," and inform the delivery of psychiatric care. Increased access to harm reduction services is crucial.

    Hepatitis B virus (HBV) infection is a major cause of chronic liver disease that may progress to liver cirrhosis and hepatocellular carcinoma. Host immune responses represent the key determinants of HBV clearance or persistence. Here, we investigated the role of the early activation marker, CD69 and effector cytokines, granzyme B (GrB) and IFN-γ in the exhaustion of innate-like TCR Vα7.2+CD4+T cells, in 15 individuals with chronic HBV (CHB) infection where six were HBV DNA+ and nine were HBV DNA-. The percentage of cytokine-producing T cells and MAIT cells were significantly perturbed in HBV patients relative to healthy controls (HCs). The intracellular expression of GrB and IFN-γ was significantly reduced in MAIT cells derived from HBV-infected patients as compared to HCs, and the levels correlated with the percentage and levels [mean fluorescence intensity (MFI)] of CD69 expression. The total expression of CD69 (iMFI) was lower in CHB patients as compared to HCs. The frequency of CD69+ cells correlated with the levels of cytokine expression (MFI), particularly in CHB patients as compared to HCs. In summary, the polyfunctionality of peripheral T cells was significantly reduced among CHB patients, especially in the TCR Vα7.2+CD4+T cells, and the levels of cytokine expression correlated with functional cytokine levels.

    Scientists working in assisted reproduction [members of Scientists in Reproductive Technology (SIRT) Australia, and subscribers of the online forums EmbryoMail and Quartec] were invited to complete an online questionnaire on the use of human blood products in assisted reproductive technologies (ART). A total of 260 started the questionnaire, with 208 (80%) completing it. A total of 62% of respondents had worked in human ART ≥8 years and 68% had post-graduate qualifications. The majority (82%) reported using products of animal or human origin, with 75% knowing why protein was added to culture media and 41% not worried by this. Almost half (49%) of respondents were unaware of regulations surrounding the use of human blood products in health care and 70% were unaware of adverse events involving human blood products in human ART. Most respondents (70%) indicated that they were not concerned about infections such as hepatitis, but agents such as prions were a cause for concern (57%). A total of 57% of respondents were unaware of alternatives, but 77% would use a suitable alternative. Using blood products in human ART is surrounded by a lack of awareness, often independent of respondents' qualifications or experience. A better understanding of these products and possible alternatives is required if informed decisions about their suitability are to be made.

    Background: According to the Association of Nephrologist in Indonesia (Pernefri) recommendation, isolation and using special hemodialysis machines are not necessary for hemodialysis (HD) patients who have been infected by hepatitis C virus (HCV), while according to the Ministry of Health Malaysia recommendation, hepatitis C patients should be dialyzed in a separate room or a separate area with a fixed partition and dedicated machines.

    Aim: The aim of this study was to identify the correlation between the recommendation which had been followed by two HD centers in different countries and the impact of that on the hepatitis C infection issue.

    Methods: A cohort prospective and retrospective study was done in this research. The study included HD patients who were followed up for 9 months and who died in the last 5 years. Universal sampling was used to select the patients based on inclusion criteria.

    Results: There was a significant relationship between HCV during the first checkup and HCV during the second checkup during the 9-month follow-up of HD patients in a HD center, Jakarta, Indonesia. The total number of patients who had hepatitis C during the first and second checkups was also different in this HD center.

    Conclusion: Besides providing special HD rooms and machines for HD patients with hepatitis C, minimizing blood transfusion to the patients on HD is also important to reduce the chance for the patients to acquire hepatitis C and to increase the percentage of survival.

    PURPOSE OF REVIEW: With increasing availability of generic direct-acting antivirals (DAAs) and associated price reductions, various governments, multilateral institutions, and donors have started providing testing and treatment for hepatitis C virus (HCV) infection. More data on the quality of these generic medicines and on cost-effectiveness of their use are becoming widely available. This review seeks to describe some of the treatment programs for HCV that are evolving in Cambodia, India, Indonesia, Malaysia, Myanmar, and Thailand.

    RECENT FINDINGS: The quality of multiple generic DAAs has been shown to be bioequivalent to innovator formulations, with generic versions achieving high cure rates in real-world settings. Although published materials are limited, there is expanding experience with local pilot and national treatment programs which are largely being funded by national governments and other institutions.

    SUMMARY: Countries and other public health stakeholders are recognizing the need to scale up HCV diagnosis and treatment programs using generic DAAs. However, local pilot or national treatment programs need to be massively expanded to eliminate HCV in high-burden areas.

    The main aim of our study was to explore the genome sequence of the inclusion body hepatitis associated Fowl adenovirus serotype 8b (FAdV-8b) UPM04217 and to study its genomic organisation. The nucleotide sequence of the whole genome of FAdV-8b UPM04217 was determined by using the 454 Pyrosequencing platform and the Sanger sequencing method. The complete genome was found to be 44,059 bp long with 57.9% G + C content and shared 97.5% genome identity with the reference FAdV-E genome (HG isolate). Interestingly, the genome analysis using ORF Finder, Glimmer3 and FGENESV predicted a total of 39 open reading frames (ORFs) compared to the FAdV-E HG that possessed 46 ORFs. Fourteen ORFs located within the central genomic region and 16 ORFs located within the left and right ends of the genome were assigned as being the high protein-coding regions. The fusion of the small ORFs at the right end terminal specifically in ORF22 and ORF33 could be the result of gene truncation in the FAdV-E HG. The frame shift mutation in ORF25 and other mutations in ORF13 and ORF17 might have lead to the emergence of genes that could have different functions. Besides, one of the minor capsid components, pVI, in FAdV-8b UPM04217 shared the highest similarity of 93% with that of FAdV-D, while only 47% similarity was found with FAdV-E. From the gene arrangement layout of the FAdV genome, FAdV-8b UPM04217 showed intermediate evolution between the FAdV-E HG and the FAdV-D although it was apparently more similar to the FAdV-E HG.

    BACKGROUND: The decision to implement new vaccines should be supported by public health and economic evaluations. Therefore, this study was primarily designed to evaluate the economic impact of switching from partially combined vaccine (Pentaxim® plus hepatitis B) to fully combined vaccine (Hexaxim®) in the Malaysian National Immunization Program (NIP) and to investigate healthcare professionals (HCPs)' and parents'/caregivers' perceptions.

    METHODS: In this economic evaluation study, 22 primary healthcare centers were randomly selected in Malaysia between December 2019 and July 2020. The baseline immunization schedule includes switching from Pentaxim® (four doses) and hepatitis B (three doses) to Hexaxim® (four doses), whereas the alternative scheme includes switching from Pentaxim® (four doses) and hepatitis B (three doses) to Hexaxim® (four doses) and hepatitis B (one dose) administered at birth. Direct medical costs were extracted using a costing questionnaire and an observational time and motion chart. Direct non-medical (cost for transportation) and indirect costs (loss of productivity) were derived from parents'/caregivers' questionnaire. Also, HCPs' and parent's/caregivers' perceptions were investigated using structured questionnaires.

    RESULTS: The cost per dose of Pentaxim® plus hepatitis B vs. Hexaxim® for the baseline scheme was Malaysian ringgit (RM) 31.90 (7.7 United States dollar [USD]) vs. 17.10 (4.1 USD) for direct medical cost, RM 54.40 (13.1 USD) vs. RM 27.20 (6.6 USD) for direct non-medical cost, RM 221.33 (53.3 USD) vs. RM 110.66 (26.7 USD) for indirect cost, and RM 307.63 (74.2 USD) vs. RM 155.00 (37.4 USD) for societal (total) cost. A similar trend was observed for the alternative scheme. Compared with Pentaxim® plus hepatitis B, total cost savings per dose of Hexaxim® were RM 137.20 (33.1 USD) and RM 104.70 (25.2 USD) in the baseline and alternative scheme, respectively. Eighty-four percent of physicians and 95% of nurses supported the use of Hexaxim® in the NIP. The majority of parents/caregivers had a positive perception regarding Hexaxim® vaccine in various aspects.

    CONCLUSIONS: Incorporation of Hexaxim® within Malaysian NIP is highly recommended because the use of Hexaxim® has demonstrated substantial direct and indirect cost savings for healthcare providers and parents/caregivers with a high percentage of positive perceptions, compared with Pentaxim® plus hepatitis B.

    Eight weeks duration of ledipasvir/sofosbuvir (LDV/SOF) can be considered in genotype 1 hepatitis C virus-infected patients who are treatment-naive, do not have cirrhosis, and have a pretreatment viral load <6,000,000 IU/mL. The effectiveness of this regimen, however, has not been fully confirmed by real-world experience. Using data from real-world cohorts, we aimed to determine the effectiveness of 8 weeks of LDV/SOF treatment, examine variables associated with relapse after treatment with this regimen, and compare the effectiveness of 8 weeks and 12 weeks of LDV/SOF treatment. To evaluate the effectiveness of 8 weeks of therapy and characteristics associated with relapse, we used individual patient data from the IFI (Institut für Interdisziplinäre Medizin), Burman's Pharmacy, and Kaiser Permanente Southern California. All patients had fibrosis staging assessed with biopsy, transient elastography, or serum biomarkers. We also performed a systematic review and meta-analysis of six additional real-world cohorts, to compare effectiveness of 8 weeks to 12 weeks duration. In our pooled data analysis, 634 patients were treated for 8 weeks with LDV/SOF, of whom all had outcomes of cure or relapse without loss to follow-up. Per protocol rates of sustained virologic response at 12 weeks were 98.1% (622/634) in the full cohort and 97.9% (571/583) among treatment-eligible patients. Exact logistic regression revealed no specific patient characteristics associated with relapse. Our meta-analysis of six additional real-world cohorts, comprised of 5,637 patients, demonstrated similar risk for relapse between 8 weeks and 12 weeks of LDV/SOF (relative risk = 0.99, 95% confidence interval 0.98-1.00).

    CONCLUSION: An 8-week duration of treatment with LDV/SOF is highly effective in properly selected patients; greater use of this regimen is recommended. (Hepatology 2017;65:1094-1103).

    Textile industries consume large volumes of water for dye processing, leading to undesirable toxic dyes in water bodies. Dyestuffs are harmful to human health and aquatic life, and such illnesses as cholera, dysentery, hepatitis A, and hinder the photosynthetic activity of aquatic plants. To overcome this environmental problem, the advanced oxidation process is a promising technique to mineralize a wide range of dyes in water systems. In this work, reduced graphene oxide (rGO) was prepared via an advanced chemical reduction route, and its photocatalytic activity was tested by photodegrading Reactive Black 5 (RB5) dye in aqueous solution. rGO was synthesized by dispersing the graphite oxide into the water to form a graphene oxide (GO) solution followed by the addition of hydrazine. Graphite oxide was prepared using a modified Hummers' method by using potassium permanganate and concentrated sulphuric acid. The resulted rGO nanoparticles were characterized using ultraviolet-visible spectrophotometry (UV-Vis), X-ray powder diffraction (XRD), Raman, and Scanning Electron Microscopy (SEM) to further investigate their chemical properties. A characteristic peak of rGO-48 h (275 cm-1) was observed in the UV spectrum. Further, the appearance of a broad peak (002), centred at 2θ = 24.1°, in XRD showing that graphene oxide was reduced to rGO. Based on our results, it was found that the resulted rGO-48 h nanoparticles achieved 49% photodecolorization of RB5 under UV irradiation at pH 3 in 60 min. This was attributed to the high and efficient electron transport behaviors of rGO between aromatic regions of rGO and RB5 molecules.

    BACKGROUND & AIMS: There is increasing interest in identifying patients with chronic hepatitis C genotype 2 or 3 infection in whom it is possible to lower the burden of therapy while retaining high levels of efficacy.

    METHODS: Treatment-naive patients with chronic hepatitis C genotype 2/3 infection were randomized to receive peginterferon alfa-2b (1.5μg/kg/wk) for 24weeks (group A); peginterferon alfa-2b (1.0μg/kg/wk) for 24weeks (group B); or peginterferon alfa-2b (1.5μg/kg/wk) for 16weeks (group C), each in combination with weight-based ribavirin (800-1200mg/d). The study population comprised two cohorts: the Hep-Net cohort enrolled in Germany and an International cohort enrolled at study sites throughout Europe and Asia. The primary end point was sustained virological response (SVR).

    RESULTS: The study included 682 patients; 80.2% had genotype 3 infection. In the intent-to-treat population, SVR rates were 66.5%, 64.3%, and 56.6% in groups A, B, and C, and were similar in Asian and white patients. Treatment differences (A vs. B and A vs. C) failed to reach the predefined margin for noninferiority of -10%; and thus groups B and C failed to show noninferiority relative to group A. Among patients with undetectable HCV RNA at week 4, SVR rates were 75.3%, 75.9%, and 72.4%, respectively. Relapse rates were 17.8%, 16.3%, and 29.3%, respectively. Treatment-emergent serious adverse events were highest in group A and lowest in group C, and adverse events leading to discontinuation were similar across treatment arms.

    CONCLUSIONS: For patients with chronic hepatitis C genotype 2/3 infection, 24weeks of peginterferon alfa-2b (1.5μg/kg/wk) plus weight-based ribavirin remains a standard-of-care therapy; however, treatment for 16weeks may be considered for patients with undetectable HCV RNA at week 4 of the treatment.

    BACKGROUND: Liver fibrosis is often accompanied by steatosis, particularly in patients with non-alcoholic fatty liver disease (NAFLD), and its non-invasive characterisation is of utmost importance. Vibration-controlled transient elastography is the non-invasive method of choice; however, recent research suggests that steatosis may influence its diagnostic performance. Controlled Attenuation Parameter (CAP) added to transient elastography enables simultaneous assessment of steatosis and fibrosis.

    AIM: To determine how to use CAP in interpreting liver stiffness measurements.

    METHODS: This is a secondary analysis of data from an individual patient data meta-analysis on CAP. The main exclusion criteria for the current analysis were unknown aetiology, unreliable elastography measurement and data already used for the same research question. Aetiology-specific liver stiffness measurement cut-offs were determined and used to estimate positive and negative predictive values (PPV/NPV) with logistic regression as functions of CAP.

    RESULTS: Two thousand and fifty eight patients fulfilled the inclusion criteria (37% women, 18% NAFLD/NASH, 42% HBV, 40% HCV, 51% significant fibrosis ≥ F2). Youden optimised cut-offs were only sufficient for ruling out cirrhosis (NPV of 98%). With sensitivity and specificity-optimised cut-offs, NPV for ruling out significant fibrosis was moderate (70%) and could be improved slightly through consideration of CAP. PPV for significant fibrosis and cirrhosis were 68% and 55% respectively, despite specificity-optimised cut-offs for cirrhosis.

    CONCLUSIONS: Liver stiffness measurement values below aetiology-specific cut-offs are very useful for ruling out cirrhosis, and to a lesser extent for ruling out significant fibrosis. In the case of the latter, Controlled Attenuation Parameter can improve interpretation slightly. Even if cut-offs are very high, liver stiffness measurements are not very reliable for ruling in fibrosis or cirrhosis.

    Purpose Selective internal radiation therapy or radioembolization (RE) shows efficacy in unresectable hepatocellular carcinoma (HCC) limited to the liver. This study compared the safety and efficacy of RE and sorafenib in patients with locally advanced HCC. Patients and Methods SIRveNIB (selective internal radiation therapy v sorafenib), an open-label, investigator-initiated, phase III trial, compared yttrium-90 (90Y) resin microspheres RE with sorafenib 800 mg/d in patients with locally advanced HCC in a two-tailed study designed for superiority/detriment. Patients were randomly assigned 1:1 and stratified by center and presence of portal vein thrombosis. Primary end point was overall survival (OS). Efficacy analyses were performed in the intention-to-treat population and safety analyses in the treated population. Results A total of 360 patients were randomly assigned (RE, 182; sorafenib, 178) from 11 countries in the Asia-Pacific region. In the RE and sorafenib groups, 28.6% and 9.0%, respectively, failed to receive assigned therapy without significant cross-over to either group. Median OS was 8.8 and 10.0 months with RE and sorafenib, respectively (hazard ratio, 1.1; 95% CI, 0.9 to 1.4; P = .36). A total of 1,468 treatment-emergent adverse events (AEs) were reported (RE, 437; sorafenib, 1,031). Significantly fewer patients in the RE than sorafenib group had grade ≥ 3 AEs (36 of 130 [27.7%]) v 82 of 162 [50.6%]; P < .001). The most common grade ≥ 3 AEs were ascites (five of 130 [3.8%] v four of 162 [2.5%] patients), abdominal pain (three [2.3%] v two [1.2%] patients), anemia (zero v four [2.5%] patients), and radiation hepatitis (two [1.5%] v zero [0%] patients). Fewer patients in the RE group (27 of 130 [20.8%]) than in the sorafenib group (57 of 162 [35.2%]) had serious AEs. Conclusion In patients with locally advanced HCC, OS did not differ significantly between RE and sorafenib. The improved toxicity profile of RE may inform treatment choice in selected patients.

    BACKGROUND: With recent improvements in vaccines and treatments against viral hepatitis, an improved understanding of the burden of viral hepatitis is needed to inform global intervention strategies. We used data from the Global Burden of Disease (GBD) Study to estimate morbidity and mortality for acute viral hepatitis, and for cirrhosis and liver cancer caused by viral hepatitis, by age, sex, and country from 1990 to 2013.

    METHODS: We estimated mortality using natural history models for acute hepatitis infections and GBD's cause-of-death ensemble model for cirrhosis and liver cancer. We used meta-regression to estimate total cirrhosis and total liver cancer prevalence, as well as the proportion of cirrhosis and liver cancer attributable to each cause. We then estimated cause-specific prevalence as the product of the total prevalence and the proportion attributable to a specific cause. Disability-adjusted life-years (DALYs) were calculated as the sum of years of life lost (YLLs) and years lived with disability (YLDs).

    FINDINGS: Between 1990 and 2013, global viral hepatitis deaths increased from 0·89 million (95% uncertainty interval [UI] 0·86-0·94) to 1·45 million (1·38-1·54); YLLs from 31·0 million (29·6-32·6) to 41·6 million (39·1-44·7); YLDs from 0·65 million (0·45-0·89) to 0·87 million (0·61-1·18); and DALYs from 31·7 million (30·2-33·3) to 42·5 million (39·9-45·6). In 2013, viral hepatitis was the seventh (95% UI seventh to eighth) leading cause of death worldwide, compared with tenth (tenth to 12th) in 1990.

    INTERPRETATION: Viral hepatitis is a leading cause of death and disability worldwide. Unlike most communicable diseases, the absolute burden and relative rank of viral hepatitis increased between 1990 and 2013. The enormous health loss attributable to viral hepatitis, and the availability of effective vaccines and treatments, suggests an important opportunity to improve public health.
