Article Synopsis
  • - The 2A protease of enterovirus species, responsible for critical steps in viral replication, is a key target for combating pediatric hand-foot-and-mouth disease and preparing for potential outbreaks.
  • - Inhibiting the 2A protease can disrupt the folding and assembly of viral capsid proteins, preventing the production of mature viral particles and presenting a strategy for antiviral treatment.
  • - A crystallographic fragment screening campaign successfully identified 75 compounds that bind to the 2A protease, with 38 unique ones targeting the active site, paving the way for the creation of broad-spectrum anti-enteroviral drugs.

Article Synopsis
  • * The 5'-untranslated region (5'-UTR) of EV-A71 contains an internal ribosome entry site (IRES) critical for viral protein translation, regulated by factors like heterogeneous nuclear ribonucleoprotein (hnRNP) A3.
  • * HnRNP A3, which typically inhibits EV-A71 replication, shifts from the nucleus to the cytoplasm during infection; knocking it down boosts viral replication, indicating it has a negative regulatory role in the life cycle of the virus inside neural cells.

Article Synopsis
  • Enterovirus 71 (EV71) is linked to hand, foot, and mouth disease, and this study examines how it affects immune cells, specifically plasmacytoid dendritic cells (pDCs) and CD4 T cells.
  • Early during EV71 infection, pDCs activate quickly, producing interferon (IFN)-α, which boosts the proliferation and differentiation of CD4 T cells and kicks off adaptive immune responses.
  • However, as the infection progresses, pDCs and CD4 T cells become less effective due to viral replication and a key pathway (CAP) that reduces inflammation, which might contribute to a tolerance in CD4 T cells.

Enteroviruses are a significant global health concern, causing a spectrum of diseases from the common cold to more severe conditions like hand-foot-and-mouth disease, meningitis, myocarditis, pancreatitis, and poliomyelitis. Current treatment options for these infections are limited, underscoring the urgent need for effective therapeutic strategies. To find better treatment option we analyzed toxicity and efficacy of 12 known broad-spectrum anti-enterovirals both individually and in combinations against different enteroviruses in vitro.

Background: Hand, foot, and mouth disease (HFMD) is an infectious disease with high morbidity and mortality rates among children under 5 years old. This study aimed to explore the health-related quality of life (HRQOL), economic burden, and related influencing factors among Chinese HFMD patients.

Methods: From January to October 2019, a longitudinal cohort study of 296 hospitalized patients (≤ 5 years old) with HFMD and their guardians was conducted using the proxy version of the 5-level EQ-5D-Y (EQ-5D-Y-5L, Y-5L) in face-to-face interviews in Shanghai, Zhengzhou, and Kunming, representing three regions with different economic development levels.

Rationale: Hand-foot-mouth disease (HFMD) caused by Enterovirus A71, complicated by cardiopulmonary failure, is associated with a high mortality rate despite intensive treatment. To date, there is a paucity of clinical management data, regarding the use of extracorporeal life support (VA-ECMO) for Enterovirus-A71 associated cardiopulmonary failure reported.

Patient Concerns: The patient in this study presented with severe HFMD complicated by cardiopulmonary failure, polymorphic ventricular tachycardia, and cardiac arrest.

Viral infections are common in children. Many can be asymptomatic or have delayed health consequences. In view of increasing availability of point-of-care viral detection technologies, with possible application in newborn screening, this review aimed to (1) identify potentially asymptomatic viruses detectable in infants under one year old, via saliva/nasopharyngeal swab, and (2) describe associations between viruses and long-term health conditions.

Background: Human enteroviruses A71 (EV-A71) and D68 (EV-D68) are the suspected causative agents of hand-foot-and-mouth disease, aseptic meningitis, encephalitis, acute flaccid myelitis, and acute flaccid paralysis in children. Until now, no cure nor mucosal vaccine existed for EV-A71 and EV-D68. Novel mucosal bivalent vaccines are highly important for preventing EV-A71 and EV-D68 infections.

An increasing number of studies have reported that atypical hand, foot, and mouth disease (HFMD) is becoming a new concern for children's health. At present, there is no official definition for atypical HFMD, but some studies have defined that it occurs at anatomic sites not listed in the definition of HFMD issued by the World Health Organization. Several pathogens have been reported to cause atypical HFMD, such as Coxsackievirus (CV)A6.

The objective of this work was to explore the application value of a new type of fluorescent nucleic acid isothermal amplification (SAT) to detect EV/EV71/CA16-SAT in children with hand-foot-mouth disease (HFMD). For this purpose, from March 2017 to September 2019, Chengdu Children's Specialized Hospital collected throat swabs from children with clinical manifestations of hand, foot and mouth disease, and used SAT technology to screen and detect universal enterovirus (EV) nucleic acid (There were 1860 children with EV-RNA) positive. Patients who are EV-RNA positive at any time: first use the same throat swab specimen to detect EV71/CA16-RNA; secondly, collect venous blood and use the colloidal gold method to detect IgM antibodies in EV71/CA16 serum.

Potential relevance of salivary legumain for the clinical diagnostic of hand, foot, and mouth disease.

J Med Virol

November 2023

Collaborative and Translation Unit for Hand, Foot and Mouth Disease (HFMD), Institute of Molecular and Cell Biology, Agency for Science, Technology and Research (A*STAR), Singapore, Singapore.

The fight against hand, foot, and mouth disease (HFMD) remains an arduous challenge without existing point-of-care (POC) diagnostic platforms for accurate diagnosis and prompt case quarantine. Hence, the purpose of this salivary biomarker discovery study is to set the fundamentals for the realization of POC diagnostics for HFMD. Whole salivary proteome profiling was performed on the saliva obtained from children with HFMD and healthy children, using a reductive dimethylation chemical labeling method coupled with high-resolution mass spectrometry-based quantitative proteomics technology.

Article Synopsis
  • Hand-foot-mouth disease (HFMD) is a common childhood infection, with atypical skin symptoms often linked to coxsackievirus A6 (CVA6), leading to unusual lesions beyond the usual areas.
  • A systematic review of 85 studies revealed that most affected children were around 2.4 years old, with typical skin findings including vesicles, papules, and bullae, particularly on arms and face, and identified CVA6 in 63% of cases.
  • The atypical presentations can cause misdiagnoses and excessive treatments, highlighting the need for better understanding and awareness of these variations to enhance patient care and infection control guidance.

Article Synopsis
  • Hymenoptera venom (HV), injected by bees and wasps during stings, can cause allergic reactions in about 3% of people, leading to severe local or systemic allergic reactions in some cases.
  • The guidelines suggest that while symptomatic therapy is needed after a severe local reaction, specific allergen immunotherapy isn't necessary unless severe reactions occur beyond the skin.
  • Clinicians should assess patients for risk factors, measure tryptase levels if reactions are significant, and test for specific IgE antibodies to diagnose sensitization to Hymenoptera venom.

In recent years, enterovirus A71 (EV-A71) infection has become a major global public health problem, especially for infants and young children. The results of epidemiological research show that EV-A71 infection can cause acute hand, foot, and mouth disease (HFMD) and complications of the nervous system in severe cases, including aseptic pediatric meningoencephalitis, acute flaccid paralysis, and even death. Many studies have demonstrated that EV-A71 infection may trigger a variety of intercellular and intracellular signaling pathways, which are interconnected to form a network that leads to the innate immune response, immune escape, inflammation, and apoptosis in the host.
