Society for Maternal-Fetal Medicine (SMFM) Consult Series #56: Hepatitis C in Pregnancy: Updated Guidelines.

Am J Obstet Gynecol 2021 Jun 8. Epub 2021 Jun 8.

In the United States, it is estimated that 1% to 4% of pregnant women are infected with hepatitis C virus, which carries approximately a 5% risk of transmission from mother to infant. Hepatitis C virus can be transmitted to the infant in utero or during the peripartum period, and infection during pregnancy is associated with an increased risk of adverse fetal outcomes, including fetal growth restriction and low birthweight. The purpose of this document is to discuss the current evidence, provide updated recommendations regarding screening, review treatment, and address management of hepatitis C virus during pregnancy.

Top Antivir Med 2020 Dec-Jan;28(3):465-468

University of Colorado, Aurora, CO, USA.

Vaccines play an important role in HIV primary care and are available for several sexually transmitted infections, including those caused by hepatitis A virus (HAV), hepatitis B virus (HBV), and human papillomavirus (HPV). HAV vaccination is increasingly important, given recent hepatitis A outbreaks and lack of immunity in many adults. A novel formulation of the hepatitis B vaccine shows promise in increasing rates of seroprotection. Read More

Preclinical safety assessment of a combined vaccine against Hepatitis a virus and enterovirus 71.

Vaccine 2021 Jun 1. Epub 2021 Jun 1.

The Institute of Medical Biology, Chinese Academic Medical Sciences & Peking Union Medical College, Kunming, China. Electronic address:

Since 2007, Hepatitis A (HAV) vaccination has been a part of the National Immunization Program of China. Recognizing enterovirus 71 (EV71) as the most important pathogen in severe hand, foot and mouth disease, an inactivated EV71 vaccine was successfully marketed in 2015. Based on the concept of one vaccine preventing two diseases and owing to similarities in vaccine preparation and the overlap of the eligible population, a combination of the inactivated HAV vaccine and inactivated EV71 vaccine is theoretically feasible and desirable.

Development of a Tetraplex qPCR for the Molecular Identification and Quantification of Human Enteric Viruses, NoV and HAV, in Fish Samples.

Microorganisms 2021 May 27;9(6). Epub 2021 May 27.

ITQB NOVA, Instituto de Tecnologia Química e Biológica António Xavier, Universidade Nova de Lisboa, Av. da República, 2780-157 Oeiras, Portugal.

Human enteric viruses such as norovirus (NoV) and hepatitis A virus (HAV) are some of the most important causes of foodborne infections worldwide. Usually, infection via fish consumption is not a concern regarding these viruses, since fish are mainly consumed cooked. However, in the last years, raw fish consumption has become increasingly common, especially involving the use of seabass and gilthead seabream in dishes like sushi, sashimi, poke, and carpaccio.

Aptamer Laden Liquid Crystals Biosensing Platform for the Detection of HIV-1 Glycoprotein-120.

Molecules 2021 May 13;26(10). Epub 2021 May 13.

Department of Chemical and Biomolecular Engineering, National University of Singapore, Engineering Drive 4, Singapore 117576, Singapore.

We report a label-free and simple approach for the detection of glycoprotein-120 (gp-120) using an aptamer-based liquid crystals (LCs) biosensing platform. The LCs are supported on the surface of a modified glass slide with a suitable amount of B40t77 aptamer, allowing the LCs to be homeotropically aligned. A pronounced topological change was observed on the surface due to a specific interaction between B40t77 and gp-120, which led to the disruption of the homeotropic alignment of LCs. Read More

Viruses 2021 May 8;13(5). Epub 2021 May 8.

Center for Vaccines and Immunity, The Abigail Wexner Research Institute at Nationwide Children's Hospital, Columbus, OH 43205, USA.

Hepatitis A virus (HAV) infection is a common cause of acute viral hepatitis worldwide. Despite decades of research, the pathogenic mechanisms of hepatitis A remain incompletely understood. As the replication of HAV is noncytopathic in vitro, a widely accepted concept has been that virus-specific cytotoxic T cells are responsible for liver injury. Read More

Hepatitis A (HA) is an acute human infectious disease caused by a positive single-stranded RNA virus (HAV). It is mainly acquired through the fecal-oral route and is primarily spread by contact between people and exposure to contaminated water and food. Recently, large outbreaks of HA have been reported by low and moderate endemicity countries, emphasizing its importance in public health and the need for rapid and large-scale diagnostic tests to support public health decisions on HA.

Role of -Acetylcysteine in the Treatment of Acute Nonacetaminophen, Nonalcoholic and Nonviral Hepatitis: A Meta-analysis.

J Can Assoc Gastroenterol 2021 Jun 15;4(3):125-130. Epub 2020 Jul 15.

Department of Medicine, McMaster University, Hamilton, Ontario, Canada.

Introduction: -acetylcysteine (NAC) has been extensively investigated for the use in acetaminophen and alcoholic hepatitis and is indicated in acetaminophen overdose. Studies assessing the effect of NAC on other forms of acute hepatitis in adult patients are limited and therefore here we aimed at evaluating the effect of NAC on survival in nonacetaminophen, nonalcoholic and nonviral hepatitis in adults.

Methods: A comprehensive literature search up to September 2019 was completed for randomized controlled trials (RCTs) comparing NAC to placebo in the management of acute nonacetaminophen, nonalcoholic and nonviral hepatitis. Read More

Risk Manag Healthc Policy 2021 20;14:2079-2087. Epub 2021 May 20.

Primary Care Unit ASL RM 1, Rome, Italy.

This narrative review is the final output of an initiative of the SIM (Italian Society of Mesotherapy). A narrative review of scientific literature on the efficacy of fractional intradermal vaccination in comparison with full doses has been conducted for the following pathogens: influenza virus, rabies virus, poliovirus (PV), hepatitis B virus (HBV), hepatitis A virus (HAV), diphtheria-tetanus-pertussis bacterias (DTP), human papillomavirus (HPV), Japanese encephalitis virus (JE), meningococcus, varicella zoster virus (VZV) and yellow fever virus. The findings suggest that the use of the intradermal route represents a valid strategy in terms of efficacy and efficiency for influenza, rabies and HBV vaccines. Read More

Immune disorders and rheumatologic manifestations of viral hepatitis.

World J Gastroenterol 2021 May;27(18):2073-2089

Department of Internal Medicine, Gastroenterology and Hepatology, Sechenov University, Moscow 119435, Russia.

Infection with hepatotropic viruses is not limited to the liver and can lead to the development of various immunological disorders (the formation of cryoglobulins, rheumatoid factor, antinuclear antibodies, autoantibodies specific for autoimmune hepatitis and primary biliary cholangitis, and others), which can manifest as glomerulonephritis, arthritis, uveitis, vasculitis (cryoglobulinemic vasculitis, polyarteritis nodosa, Henoch-Schonlein purpura, isolated cutaneous necrotizing vasculitis), and other rheumatologic disorders, and be a trigger for the subsequent development of autoimmune hepatitis and primary biliary cholangitis. A further study of the association between autoimmune liver diseases and hepatotropic virus infection would be useful to assess the results of treatment of these associated diseases with antiviral drugs. The relationship of these immune disorders and their manifestations with hepatotropic viruses is best studied for chronic hepatitis B and C. Read More

Fundação Oswaldo Cruz, Instituto Leônidas e Maria Deane, Manaus, AM, Brasil.

This article discusses viral hepatitis, a theme addressed by the Clinical Protocol and Therapeutic Guidelines to Comprehensive Care for People with Sexually Transmitted Infections and, more precisely, by the Clinical Protocols and Therapeutic Guidelines for Hepatitis B and Hepatitis C and Coinfections, published by the Brazilian Ministry of Health. Besides the broad spectrum of health impairment, hepatitis A, B, and C viruses also present different transmission forms, whether parenteral, sexual, vertical, or fecal-oral. Among the strategies suggested for the control of viral hepatitis, in addition to behavioral measures, are expanded diagnosis, early vaccination against hepatitis A and hepatitis B viruses, and access to available therapeutic resources.
