RESUMO

Viral hepatitis (VH) is a significant public health issue with tremendous potential to aggravate into chronic hepatitis, liver cirrhosis, and hepatocellular carcinoma. Recent decade has witnessed remarkable uprising in the drug development and effective treatment of VH. An upsurge is seen in identification of antiviral therapies with low rates of viral resistance, the improvement of Hepatitis B Virus (HBV) vaccination and the development of direct-acting antivirals for Hepatitis C Virus (HCV). But unfortunately, the "2030 worldwide eradication" objective of World Health Organization (WHO) is still unmet. It can be largely attributed to the deficit faced by the healthcare system concerning screening and diagnosis. A timely, accurate and comprehensive screening; encompassing maximum population coverage is essential to combat this disease. However, advancements in VH diagnostics remain inadequate and with a marginal use in routine practice. This paper deliberates upon the lacunae in traditional and prevailing diagnostic methodology of viral hepatitis, especially their inadequacy in meeting the unique situations prevailing low- and middle-income countries (LMIC).

RESUMO

Viral hepatitis accounts for a significant global disease burden and mortality, both in children and adults. There are significant differences in the viral etiology, epidemiology, and complications in children worldwide. Children of all ages may have devastating complications with a significant risk of mortality and long-term morbidity because of viral hepatitis. Liver transplantation is the only curative option for pediatric patients with end-stage liver disease, hepatocellular carcinoma, or acute liver failure because of viral hepatitis. The introduction of universal vaccination for hepatitis B across the world and hepatitis A in some countries had led to significant changes in the incidence of disease and the need for liver transplantation for the complications of viral hepatitis in children. The development of effective treatment with directly acting antiviral agents for hepatitis C has already transformed outcomes in adults and children and reduced the need for liver transplantation. Although newer therapy for hepatitis B is being evaluated in adults, current therapy for children is not curative, indicating the need for lifelong therapy and potential necessity for liver transplantation. The recent epidemic of acute hepatitis in children across the world has highlighted the importance of understanding the etiology of unusual causes for acute liver failure and the urgent need for liver transplantation.

RESUMO

BACKGROUND: The incidence of acute liver failure from herpes simplex virus is rare. CASE PRESENTATION: A 71-year-old Japanese man was diagnosed with acute liver failure and was transferred to our hospital. Steroid therapy, plasma exchange, and hemodiafiltration were started for liver failure, and antimicrobial therapy was initiated for pneumonia. Staphylococcus epidermidis was detected in blood culture. Skin rash appeared; a positive anti-herpes simplex virus result led to the diagnosis of acute liver failure from herpes simplex virus. Hence, acyclovir was started. After blood tests improved, treatments for acute liver failure were discontinued. Antimicrobial therapy was continued; however, he died. In this case, persistent bacteremia and drug-induced liver damage due to acyclovir may have contributed to his death. CONCLUSIONS: Acute liver failure can lead to complications and death. Thus, careful observation is crucial, even if the patient has shown some improvements.

RESUMO

A decline in the HIV workforce has led to a crisis of insufficient expertise to manage people with HIV (PWH), roughly a quarter of whom are coinfected with hepatitis C. Task shifting to nonspecialist providers can contribute to solving the HIV workforce shortage problem, but nonspecialist providers require sufficient training and support to acquire and retain the necessary knowledge and skills. Digital tools including mobile applications (apps) and telementoring which utilizes telecommunication technology for education and skill acquisition can be used for professional development. Described is the development and dissemination of a mobile app specifically for providers managing HIV/HCV coinfection in the United States. The app, through provider professional development, facilitates access to curative HCV treatment in PWH, encourages integration of HCV care into primary care and contributes to national goals to eliminate HIV and viral hepatitis by 2030.

RESUMO

In order to ascertain the mechanism underlying the therapeutic efficacy of Bush sophora root polysaccharides (BSRPS) and phosphorylated Bush sophora root polysaccharides (pBSRPS) in the treatment of in duck viral hepatitis (DVH), an investigation was conducted to assess the protective impact of BSRPS and pBSRPS against duck hepatitis A virus type 1 (DHAV-1) induced mitochondrial dysfunction both in vivo and vitro. The BSRPS underwent modification through the utilization of the sodium trimetaphosphate - sodium tripolyphosphate method, and was subsequently characterized though Fourier infrared spectroscopy and scanning electron microscopy. Following this, the degree of mitochondrial oxidative damage and dysfunction was described through the use of fluorescence probes and various antioxidative enzyme assay kits. Furthermore, the utilization of transmission electron microscopy facilitated the observation of alterations in the mitochondrial ultrastructure within the liver tissue. Our findings demonstrated that both BSRPS and pBSRPS effectively mitigated mitochondrial oxidative stress and conserved mitochondrial functionality, as evidenced by heightened antioxidant enzyme activity, augmented ATP production, and stabilized mitochondrial membrane potential. Meanwhile, the histological and biochemical examinations revealed that the administration of BSRPS and pBSRPS resulted in a reduction of focal necrosis and infiltration of inflammatory cells, thereby mitigating liver injury. Additionally, both BSRPS and pBSRPS exhibited the ability to maintain liver mitochondrial membrane integrity and enhance the survival rate of ducklings infected with DHAV-1. Notably, pBSRPS demonstrated superior performance in all aspects of mitochondrial function compared to BSRPS. The findings indicated that maintaining mitochondrial homeostasis is a crucial factor in DHAV-1 infections, and the administration of BSRPS and pBSRPS may mitigate mitochondrial dysfunction and safeguard liver function.

RESUMO

Renal transplantation is the most beneficial treatment in patients with chronic kidney disease (CKD), increasing life expectancy and improving quality of life. A better understanding of organ and tissue functions, the development of surgical techniques, and new and effective immunosuppressive and antimicrobial drugs increase the success of transplantation. However, the number of renal transplantations from living and cadaveric donors is not at the desired frequency. Among the leading causes of the restrictions for transplantation are both the recipients' and donors' chronic diseases. While hepatitis B and C infections are a significant problem affecting the number and success of renal transplantations, the innovation of hepatitis C virus treatments has improved outcomes. Thus, the recipient and donor hepatitis B and C virus infections are no longer considered as relative contraindications for renal transplantation. This review discusses the management of patients and donors with hepatitis B and hepatitis C in renal transplantation.

RESUMO

INTRODUCTION AND OBJECTIVES: The Choosing Wisely (CW) initiative aims to improve daily practice supported by evidence concerning unnecessary medical tests, procedures, and treatments. This philosophy is essential in managing viral hepatitis (VH), which primary care physicians increasingly carry out. It is also essential to achieving disease elimination. Thus, the aim of our study was to propose evidence-based CW recommendations in VH. MATERIALS AND METHODS: The Brazilian Society of Hepatology (SBH) formed a panel of experts in VH who selected evidence-based CW recommendations, which were subsequently scrutinized and ranked by all members of SBH using a web-based approach. RESULTS: Five recommendations were chosen in order of importance: 1) do not order anti-HCV testing after achieving sustained virological response; 2) do not request serial HCV viral load to evaluate HCV progression, 3) do not add ribavirin to direct-acting antivirals in non-cirrhotic, naïve HCV patients; 4) do not screen for hepatocellular carcinoma in HCV patients with none to moderate fibrosis (≤ F2); 5) do not request anti-HBs after HBV vaccination, except for children born to HBV-infected mothers, hemodialysis patients, healthcare professionals, people who have had sexual contact with chronic HBV carriers, HIV-positive persons and immunocompromised individuals (hematopoietic stem-cell transplant recipients or persons receiving chemotherapy). CONCLUSIONS: CW recommendations may help general practitioners adopt a more rational and cost-effective approach in managing patients with VH in Brazil and Latin America, leading to lesser waste or harm to patients.

RESUMO

Viral hepatitis remains a significant global health problem. All forms of viral hepatitis A through E (A-E) can lead to acute symptomatic infection, while hepatitis B and C can lead to chronic infection associated with significant morbidity and mortality related to progression to cirrhosis, end-stage-liver disease, and liver cancer. Viral hepatitis occurs worldwide, though certain regions are disproportionately affected. We now, remarkably, have highly effective curative regimens for hepatitis C, and safe and tolerable medications to suppress hepatitis B activity, and to prevent liver damage and slow disease progression. We have effective vaccines for hepatitis A and B which provide long-lasting immunity, while improved sanitation and awareness can curb outbreaks of hepatitis A and E. However, more effective and available preventive and curative strategies are needed to achieve global eradication of viral hepatitis. This review provides an overview of the epidemiology, transmission, diagnosis, and clinical features of each viral hepatitis with a primary focus on current and future therapeutic and curative options.

RESUMO

Viral hepatitis infections are a great burden in children who have received liver transplant. Hepatotropic viruses can cause liver inflammation that can develop into liver graft fibrosis and cirrhosis over the long term. Immunological reactions due to viral hepatitis infections are associated with or can mimic graft rejection, rendering the condition difficult to manage. Prevention strategies using vaccinations are agreeable to patients, safe, cost-effective and practical. Hence, strategies to eliminate viral hepatitis A and B focus mainly on immunization programmes for children who have received a liver transplant. Although a vaccine has been developed to prevent hepatitis C and E viruses, its use is not licensed worldwide. Consequently, eliminating hepatitis C and E viruses mainly involves early detection in children with suspected cases and effective treatment with antiviral therapy. Good hygiene and sanitation are also important to prevent hepatitis A and E infections. Donor blood products and liver grafts should be screened for hepatitis B, C and E in children who are undergoing liver transplantation. Future research on early detection of viral hepatitis infections should include molecular techniques for detecting hepatitis B and E. Moreover, novel antiviral drugs for eradicating viral hepatitis that are highly effective and safe are needed for children who have undergone liver transplantation.

RESUMO

According to the current research evidence, the therapy of nonsteroidal anti-inflammatory drugs (NSAIDs) might effectively decrease the risk of hepatocellular carcinoma (HCC) incidence. Investigations have been conducted on the relationship between NSAIDs (aspirin and nonaspirin NSAIDs) and the risk of HCC incidence. We searched the PubMed, Web of Science, Embase and Cochrane Library databases for cohort studies published prior to 15 March 2020 and screened eligible studies. There were a total of 12 eligible studies (published between 2012 and 2020). We observed a lower risk of HCC among aspirin users [hazard ratio 0.53; 95% confidence interval (CI), 0.43-0.65]. However, there were no statistically significant associations discovered between nonaspirin NSAID use and the risk of HCC incidence (hazard ratio 0.95; 95% CI, 0.79-1.15). Furthermore, aspirin use has also been found to reduce the risk of HCC in patients with cirrhosis or viral hepatitis compared to that in the general population (hazard ratio 0.15; 95% CI, 0.10-0.23; hazard ratio 0.65; 95% CI, 0.56-0.76, respectively). Moreover, no statistical associations were found between aspirin use and a higher risk of bleeding risk, with a hazard ratio value of 0.76 (95% CI, 0.51-1.13). In summary, the conducted meta-analysis reveals that aspirin, rather than nonaspirin NSAIDs, can significantly decrease the risk of HCC, particularly in patients with cirrhosis or viral hepatitis.

RESUMO

O Brasil é signatário do documento da Organização Mundial da Saúde (OMS) para eliminação das hepatites virais até 2030. Uma das estratégias para eliminação das hepatites virais é aumentar o número de diagnósticos e tratamentos. A migração dos medicamentos de hepatites virais crônicas B e C do componente especializado para o componente estratégico da assistência farmacêutica foi regulamentado pela portaria 1537 do Ministério da Saúde de Junho de 2020 e normatizada pela Nota Técnica 319 de 2020. Para essa transição foi organizado um cronograma com as etapas do processo e implantação do Sistema de Controle Logístico de Medicamentos (SICLOM) nos estados. O SICLOM é um sistema de cadastro de usuário, dispensação dos medicamentos, controle de estoque, avaliação dos critérios para prescrição dos medicamentos, além de emitir relatórios sobre quantidade de medicamentos dispensados. Uma etapa fundamental do processo foi a pactuação das Unidade Dispensadoras Municipais (UDM) no âmbito das Comissões Intergestores Regionais (CIR) e, posteriormente, na Comissão Intergestores Bipartite (CIB) para deliberar que essas unidades iniciassem o processo como farmácias dispensadoras de medicamentos de hepatites B e C no componente estratégico, utilizando o sistema SICLOM, no Estado do Rio de Janeiro. O objetivo deste trabalho é descrever o processo e avaliar os resultados relacionados ao número de pontos de atendimento e o quantitativo de tratamentos dispensados no período de julho de 2021 a fevereiro de 2022 no Estado do Rio de Janeiro. A metodologia compreendeu uma revisão da literatura sobre o papel do tratamento como estratégia de eliminação das hepatites virais e a descrição das atividades previstas e realizadas na linha do tempo desde o início do processo após o embasamento legal e da publicação das normativas e a extração dos dados e informações sobre o número de tratamentos do SICLOM. A migração resultou em 1084 tratamentos de julho a dezembro de 2021, correspondendo a 56,4% do total dos 1922 tratamentos dispensados pelo Componente Especializado da Assistência Farmacêutica (CEAF) durante todo o ano de 2020. A migração transcorreu com sucesso, aumentou de 29 polos de dispensação especializados para 61 UDM que são as farmácias do componente estratégico, tornando a dispensação mais ágil do que a espera anterior. Apesar dos efeitos negativos provocados pela pandemia pode-se considerar que houve um grande avanço na política pública de assistência às hepatites virais.


Brazil is a signatory country to the World Health Organization (WHO) document for the elimination of viral hepatitis by 2030. One of the strategies to eliminate viral hepatitis is to increase the number of diagnoses and treatments. The migration of drugs for chronic viral hepatitis B and C from the specialized component to the strategic component of pharmaceutical care was regulated by ordinance 1537 of the Ministry of Health of June 2020 and standardized by Technical Note 319 of 2020. A schedule was organized for this transition with the steps of the process and implementation of the logistics and dispensing system (SICLOM) in the states. SICLOM is a user registration system, drug dispensing, inventory control, evaluation of drug prescription criteria, in addition to issuing reports on the quantity of drugs dispensed. A fundamental step in the process was the agreement between the Municipal Dispensing Units (UDM) within the scope of the Regional Inter-management Commissions (CIR) and, later, in the Bipartite Inter-management Commission (CIB) to decide that these units would start the process as pharmacies that dispense hepatitis drugs. B and C in the strategic component, using the SICLOM system, in the State of Rio de Janeiro. The objective of this work is to describe the process and evaluate the results related to the number of service points and quantitative of treatments dispensed from July/2021 to February/2022 in the State of Rio de Janeiro. The methodology included a literature review on the role of treatment as a strategy to eliminate viral hepatitis, and the description of the activities planned and carried out in the timeline since the beginning of the process after the legal basis and the publication of norms, and the extraction of data and information on the number of treatments from SICLOM. The migration resulted in 1084 treatments from July to December 2021, corresponding to 56.4% of the total 1922 treatments dispensed by the Specialized Pharmaceutical Assistance Component (CEAF) throughout 2020. The migration was successful, increasing from 29 specialized dispensing centers to 61 DMUs, which are the pharmacies of the strategic component, making dispensing more agile than the previous wait. Despite the negative effects caused by the pandemic, it can be considered that there was a great advance in the public policy of assistance to viral hepatitis.

RESUMO

Chronic infections with either hepatitis B or C virus (HBV or HCV) are among the most common risk factors for developing hepatocellular carcinoma (HCC). The hepatocarcinogenic potential of these viruses is mediated through a wide range of mechanisms, including the induction of chronic inflammation and oxidative stress and the deregulation of cellular pathways by viral proteins. Over the last decade, effective anti-viral agents have made sustained viral suppression or cure a feasible treatment objective for most chronic HBV/HCV patients. Given the tumorigenic potential of HBV/HCV, it is no surprise that obtaining sustained viral suppression or eradication proves to be effective in preventing HCC. This review summarizes the mechanisms by which HCV and HBV exert their hepatocarcinogenic activity and describes in detail the efficacy of anti-HBV and anti-HCV therapies in terms of HCC prevention. Although these treatments significantly reduce the risk for HCC in patients with chronic viral hepatitis, this risk is not eliminated. Therefore, we evaluate potential strategies to improve these outcomes further and address some of the remaining controversies.
