Moreover, ETAR administration in sucking mice with a dosage of 12.5 or 25 mg/kg at 10 days post HTNV infection could significantly increase the survival rate from 10 to 25%, an effect equal to that of RBV (Chung et al., 2008). In contrast, there are more recent reports published by Chinese researchers indicating that there is still no effective prophylactic vaccine directed at HFRS (Zhang et al., 2007). Although NAbs from convalescent patient or immunized animals could obviously restrain hantaviral infection and improve disease outcome, purified human or humanized NAbs against hantaviruses with increased security and efficacy should be developed for clinical experiments. When mixed together, the response to PUUV was greater than that to the HTNV DNA vaccine, and both DNA vaccines had immunogenicity (Hooper et al., 2014). Chung D. H., Vastermark A., Camp J. V., Mcallister R., Remold S. K., Chu Y. K., et al. Hantavirus Vaccine - an overview | ScienceDirect Topics There is no vaccine for hantavirus infection. Truncated recombinant puumala virus nucleocapsid proteins protect mice against challenge, Insufficient efficacy and safety of intravenous ribavirin in treatment of haemorrhagic fever with renal syndrome caused by. Characteristics of passive immunity against hantavirus infection in rats. (2004). A maximum likelihood phylogenetic tree of the complete amino acid and CDS sequence of the M segment of hantaviruses was made based on the international Committee on Taxonomy of Viruses (ICTV) updated taxonomy of the order Bunyavirales in 2019 (see Figure 3). (2018). The https:// ensures that you are connecting to the Vaccines and Therapeutics Against Hantaviruses - PMC Therefore, it is necessary to carry out enhanced immunization within 26 months to provide timely protection for high-risk groups (Song et al., 2016). Hantaviral NP could bind to an evolutionary conserved sequence at the 5 terminus of hantaviral genomic RNA. Multivalent presentation of antihantavirus peptides on nanoparticles enhances infection blockade. Zhang S., Wang S., Yin W., Liang M., Li J., Zhang Q., et al. Interferon-induced transmembrane protein 3 inhibits. For HFRS therapy, RBV-treated suckling mice had a higher survival rate upon HTNV infection than the placebo control group (Huggins et al., 1986). Favipiravir could attenuate the viral RNA replication level and decrease the progeny virus yield of SNV and ANDV in vitro. Hantavirus vaccine is a vaccine that protects in humans against hantavirus infections causing hantavirus hemorrhagic fever with renal syndrome (HFRS) or hantavirus pulmonary syndrome (HPS). Nevertheless, it should also be noted that the foresaid two patients had spleen abnormalities, which might be related to the curative effect of icatibant. Hide Vaccines and Medicines Check the vaccines and medicines list and visit your doctor at least a month before your trip to get vaccines or medicines you may need. (2008). Background: Hantaviral diseases can have a high case fatality rate within the absence of broadly effective antiviral treatments or vaccines. The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest. Gavrilovskaya I. N., Gorbunova E. E., Mackow N. A., Mackow E. R. (2008). Treatment of hantavirus pulmonary syndrome - PMC - National Center for These data were published by Chinese literatures. Antoniukas et al. (2005). Most studies measure antibody efficacy through the focus reduction neutralization test (FRNT) and hemagglutination inhibition (HI) test at the cellular level, as well as animal experiments against lethal hantavirus challenge (sucking mice or newborn rat models for HTNV or SEOV infection and hamster models for ANDV or SNV infection) (Zhang et al., 1989; Xu et al., 2002; Manigold and Vial, 2014). 8600 Rockville Pike Most of the time, these side effects are minor. Clin. Cheng L. F., Wang F., Zhang L., Yu L., Ye W., Liu Z. Y., et al. It is speculated that RBV treatment might be ineffective once HCPS progresses to the cardiopulmonary phase. Hantavirus pulmonary syndrome also referred to as HPS, is a disease in which, in the late stage of infection with a hantavirus subtype. Facts about hantavirus - European Centre for Disease Prevention and Control Yamanishi K., Tanishita O., Tamura M., Asada H., Kondo K., Takagi M., et al. B., et al. Treatment may include oxygen therapy, medications, ventilation and dialysis. Different colors represent different clade. Rabbits were vaccinated with HCPS mixture (ANDV and SNV plasmid), HFRS mixed (HTNV and PUUV plasmid), or HCPS/HFRS mixture (all four plasmids) by mEP. Review of an inactivated vaccine against hantaviruses. The application of autophagy inhibitors, including 3-MA and CQ, could significantly enhance type I IFN responses and inhibit HTNV replication both in vitro and in vivo. For the first time since 1997, Uruguay has experienced HCPS cases, with an average of nine cases per year. Early Signs of Hantavirus, Treatment, Contagious, Prevention & Test Hooper J. W., Josleyn M., Ballantyne J., Brocato R. (2013). Several studies have shown that pretreatment with type I IFN could effectively inhibit hantaviral infection. Additionally, research on broadly neutralizing antibodies against hantaviruses is still lacking. VEGF upregulation in viral infections and its possible therapeutic implications. Most vaccine side effects are not dangerous. Safronetz D., Falzarano D., Scott D. P., Furuta Y., Feldmann H., Gowen B. Twin Injector electroporation device. In 2017, the recurrence of global outbreak of HFRS has drawn renewed attention to this old disease, which seriously threatens human health. Supportive care is universally applied for HFRS or HCPS, and the specific treatments depend on clinical findings of different disease phases. In the US, 34 states have confirmed and recorded HCPS cases since 1993 (Prince and Lieberman, 2013). This phylogeny shows the modest genetic diversity of the virus family. Huggins J. W., Kim G. R., Brand O. M., Mckee K. T., Jr. (1986). Kruger D. H., Ulrich R. G., Hofmann J. On the 4th or 5th day after injection, monkey serum protected 100% of hamsters from fatal diseases (Custer et al., 2003). Like all medicines, no vaccine is completely effective. Recent approaches in hantavirus vaccine development - PubMed We recommend that people with herpes have the COVID vaccine - or any vaccines offered. A neutralizing recombinant human antibody Fab fragment against. The spleen cells of immunized mice had an enhanced ability to secrete IFN- and IL-2, increasing CTL activity (Cheng et al., 2016). The diversity between different Puumala virus: N-linked glycosylation occurs at three sites in Gn (N142, N357, and N409), and at one site in Gc (N937). Spik et al. There is no vaccine against HPS, however there are four types in development: three in phase 1 of clinical trials and one in phase 2a. Favipiravir (Avigan; T-705) was initially discovered in 2002 as an antiviral drug selectively inhibiting the RdRp of influenza virus and then reported to have a high activity against a panel of Bunyaviruses (Gowen et al., 2007; Westover et al., 2016). The vascular endothelial growth factor (VEGF) theory was first proposed and studied in depth. RBV and ETAR are nucleoside analogs that interfere with viral replication. Effectiveness of inactivated hantavirus vaccine on the disease severity of hemorrhagic fever with renal syndrome. They are composed of 2030% fat, >50% protein, 7% carbohydrates, and 2% RNA. Potential therapeutic strategies for hantaviral infection. (2016). In an attempt to develop HPS medical countermeasures, we constructed an expression plasmid, pWRG/AND-M, that contains the full-length M genome segment of Andes virus (ANDV), a South American hantavirus. Hantavirus infection in humans and rodents, Northwestern Argentina. The HTNV M gene has protective effects against HTNV, SEOV, and DOBV in hamsters. Progress on the Prevention and Treatment of Hantavirus Disease Despite inactivated hantavirus vaccines being licensed for human use in China and Korea, no such vaccine has been approved in the US or Europe (Tian and Stenseth, 2019). In 2008, the first locally acquired case of HFRS caused by the SEOV was confirmed. (2007). Antonen J., Leppanen I., Tenhunen J., Arvola P., Makela S., Vaheri A., et al. Inhibition of bunyaviruses, phleboviruses, and hantaviruses by human MxA protein. This finding indicates that the vaccination program can induce effective humoral immunity in northwestern China and can be maintained up to 33 months after vaccination (Li et al., 2017) (Table 1). de Carvalho Nicacio C., Lundkvist A., Sjolander K. B., Plyusnin A., Salonen E. M., Bjorling E. (2000). Virus Host . Abudurexiti A., Adkins S., Alioto D., Alkhovsky S. V., Avsic-Zupanc T., Ballinger M. J., et al. Preventive measures against hantaviral infection, especially vaccine development, are essential for future pandemics. Of the two diseases, HPS is more severe with an approximate 40% mortality across the Americas. (2016). Second, more than three-quarters of Americans have been infected with Covid, providing natural immunity from . Later symptoms include trouble breathing and a rapid heartbeat. Currently, there are no vaccines or therapeutics for hantavirus-related diseases available. Robert F. Kennedy Jr. has long been a vaccine skeptic and has claimed he was injured by a vaccine. (2017). Hantavirus infections for the clinician: from case presentation to diagnosis and treatment. Hantavirus is a disease caused by one of several types of hantaviruses. 2019ZDLSF02-03). (2018). In vitro and in vivo activity of ribavirin against. He's running for president with endorsements from Jack Dorsey and other tech titans. The interferon-induced IFITM3 protein was able to inhibit HTNV infection in both HUVEC and A549 cells by inhibiting virus entry (Xu-Yang et al., 2016). We think that this information will shed light on the rational development of new vaccines and treatments. In 1999, HFRS candidate naked DNA vaccine was constructed by the subcloning method. Biology | Ask The Experts What Caused the Yosemite Hantavirus Outbreak? Frontiers | Vaccines and Therapeutics Against Hantaviruses The study of coding gene products is of great significance for the design of new vaccines (Johansson et al., 2004). (2016). In Paraguay, an HCPS case was first found in the Chako region in 1995. Another place with a high incidence of HFRS is Qingdao city of Shandong Province, where HFRS incidence is three times higher than the national average, reaching 0.83/100,000 (Jiang et al., 2017). Hantaviruses belong to the Family Hantaviridae of Bunyavirales and are a kind of enveloped single negative chain RNA virus (Abudurexiti et al., 2019). Early symptoms include fever, fatigue and aches. The maximal volumetric yield of N protein was 316 mg L. P40-Puu118 in particular is a good candidate for a recombinant vaccine against PUUV. Detection and cloning of PUUV-specific CTLs from PBMCs of patients with NE by recombinant PUUV vaccinia virus led to the isolation of an HLA-A24-restricted CTL cell line recognizing the G2 protein, and its 9-mer epitope was determined (Terajima et al., 2002). As increased VEGF content has been noted in the plasma of HFRS and HCPS patients and is closely related to disease severity in the acute phase (Bird et al., 2016; Pal et al., 2018), it is feasible to repurpose those FDA-approved drugs targeting vasoactive mediators for use as hantaviral infection therapy. Get the inside scoop on today's biggest stories in business, from Wall . In addition, recombinant vaccinia virus carrying PUUV N or the first half of the G2 gene was constructed. Although several antivirals have been proven to be protective in vitro or in vivo, there still exist some problems for their clinical application. Pini N., Levis S., Caldern G., Ramirez J., Bravo D., Lozano E., et al. Zhao C., Sun Y., Zhao Y., Wang S., Yu T., Du F., et al. The distribution map of hantavirus cases reported in recent Chinese literatures is summarized in Figure 1. Further studies showed that pVAX-LAMP/Gn established a memory response during long-term protection (6 months) in mice. The number of hantavirus cases by year in different states is summarized in Figure 2. In the later stages of the disease,. Johansson P., Olsson M., Lindgren L., Ahlm C., Elgh F., Holmstrom A., et al. The Hantavirus Gc envelope glycoprotein acts as a viral fusion protein that is essential for viral entry. The interferon-induced MxA protein, a GTPase with extensive antiviral activity, notably against influenza viruses, was reported to inhibit HTNV and PUUV replication in Vero cells (Frese et al., 1996). The clinical presentations may vary according to viral strains prevalence in different regions. Travelers can protect themselves by taking the following steps. It has been demonstrated that Gc shares similar features with class II fusion proteins, which means that three domains of viral fusion proteins are connected by a stem region anchoring in the viral envelope (Cifuentes-Munoz et al., 2011). All recombinant proteins linked to rP40 induced high antibody responses, indicating that rP40 is a carrier protein with potential for use in other vaccines. The outer membrane of hantavirus is composed of Gn and Gc glycoprotein, which mediates the recognition of and entry into host cells. However, a clinical trial for HFRS caused by PUUV infection in Russia showed that RBV could not improve patient condition, especially reducing viral load, and that RBV could increase the occurrence of side effects of RBV, including rash, sinus bradycardia, hyperbilirubinemia, and reduced hemoglobin. All rodent droppings are potentially harmful. The coronavirus vaccines do not contain a live virus. There is currently no effective treatment available for either HFRS or HCPS. Murphy M. E., Kariwa H., Mizutani T., Tanabe H., Yoshimatsu K., Arikawa J., et al. In North America, infection by Andes virus (ANDV) and Sin Nombre virus (SNV) manifests in mainly the lung and leads to hantavirus pulmonary syndrome (HPS) or hantavirus cardiopulmonary syndrome (HCPS), with high mortality rates; in Europe, infection by Puumala virus (PUUV) and Dobrava-Belgrade virus (DOBV) typically causes a milder form of HFRS, nephropathia epidemica (NE) (Echterdiek et al., 2019). Frese M., Kochs G., Feldmann H., Hertkorn C., Haller O. Zheng Y., Zhou B. Y., Wei J., Xu Y., Dong J. H., Guan L. Y., et al. Rhesus monkeys inoculated with pWRG/AND-M with gene guns produced very high levels of neutralizing antibodies that neutralized not only ANDV but also other HCPS-related hantavirus strains, such as SNV. A maximum clade credibility tree of the complete amino acid sequence of the protein encoded by the M segment of viruses belonging to Hantavirus. Intermittent hemodialysis (IHD) is the first choice to improve uremia condition and rectify kidney dysfunction in patients with acute kidney injury. (2013). Do the best for yourself, get yourself protected against COVID: a serious, life-threatening virus. Brocato R., Josleyn M., Ballantyne J., Vial P., Hooper J. W. (2012). Phase 4 clinical trials of inactivated hantavirus vaccine showed that the median OD values of IgG antibody were 0.005 (0.0040.016), 0.116 (0.0360.620), 0.320 (0.0650.848), and 0.128 (0.0110.649), and that the positivity rate was 7.7, 40.6, 62.2, and 48.2% at pre-vaccination, 1 month after the two primary doses, at the booster dose and at 18 months after the booster dose, respectively. Two recombinant human monoclonal antibodies that protect against lethal. However, a double-blind clinical trial in Chile failed to observe a significantly improved outcome between methylprednisolone recipients and placebo recipients for HCPS. Hantavirus Induced Kidney Disease - PMC - National Center for Then, the authors tried to produce the pan-hantavirus vaccine with a mixed plasmid DNA vaccine. Hantaviruses - GOV.UK Hantaviruses can cause a range of flu-like symptoms that progress over days and weeks. Insect cell-produced recombinant protein subunit vaccines protect against. Nucleocapsid protein of cell culture-adapted. The recommended schedule for vaccination is two doses 1 month apart, as a primary vaccination, and one booster 12 months later. Chung D. H., Kumarapperuma S. C., Sun Y., Li Q., Chu Y. K., Arterburn J. In both mice strains, DOBV rN protein induced N-specific antibodies of all IgG sub classes, suggesting a mixed Th1/Th2 immune response. A molecular-level account of the antigenic hantaviral surface. Accessibility (2018). We also can observe that the average annual number of cases in the cities of Shannxi, Shandong, and Jiangxi Province rank the top three (Supplementary Figure 1). Jung J., Ko S. J., Oh H. S., Moon S. M., Song J. W., Huh K. (2018). The high rate of mortality could be reduced if effective therapeutics could be discovered for treatment . In China, a double-blind placebo-controlled clinical trial enrolled 242 HFRS patients caused by HTNV infection. DNA vaccines for HFRS: laboratory and clinical studies. The Supplementary Material for this article can be found online at: https://www.frontiersin.org/articles/10.3389/fmicb.2019.02989/full#supplementary-material, National Library of Medicine When the Covid pandemic hit, the CDC made a travel health notice advising against cruise . Several compounds, namely, lead inhibitor K31, K34, and 103772, were reported to interrupt the NP-RNA interaction against SNV and ANDV infection. Hemorrhagic fever with renal syndrome (HFRS) in Poland. Placebo-controlled, double-blind trial of intravenous ribavirin for the treatment of hantavirus cardiopulmonary syndrome in North America. Virus-like particle vaccines are similar to natural virus particles but lack infectious genetic material. Another case report also confirmed the efficient treatment of icatibant in a 67-year-old female HFRS patient (Laine et al., 2015). Early admission to the intensive care unit is warranted as the disease is likely to progress and mechanical ventilation, as well as extracorporeal membrane oxygenation, may be warranted in some patients. Overall, 33.3% of the effective vaccination group had three stages of AKI, compared with 54.5% for the non-vaccinated group. Phase I clinical pharmacology and toxicity tests for HTNV NAbs in healthy volunteers were performed, and phase II clinical trials to assess the therapeutic efficacy of these NAbs in early stages of HFRS were carried out in endemic settings in China (Xu et al., 2002, 2009). As a potent mutagen, RBV could induce RNA mutagenesis in subsequent generations of HTNV virions (Chung et al., 2013), while it is not expected that ETAR induces mutation, probably due to the lack of pseudobase pair presence (Chung et al., 2008). The crystal structure of HTNV Gn is very similar to that of PUUV Gn, which confirms that hantavirus Gn is conserved in hantavirus (Li et al., 2016; Rissanen et al., 2017). Delayed favipiravir administration after the onset of viremia exerted no protective effects against ANDV infection. (2012). Evidence of infection was monitored after challenge with SEOV. The total number of HFRS patients hospitalized in South Korea fell sharply from 1234 in 1991 to 415 in 1997 (Cho et al., 2002). Treatment for both is primarily supportive as there is no specific treatment for hantavirus infections. A first step in developing prevention measures is determining what type of immune response is protective. (2019). The incidence of diabetic ketoacidosis, a potentially life-threatening complication of new-onset type 1 diabetes, rose by 26% from 2019 to 2020, probably because people were hesitant or unable to . Human hantavirus infections: epidemiology, clinical features, pathogenesis and immunology. Brocato R. L., Josleyn M. J., Wahl-Jensen V., Schmaljohn C. S., Hooper J. W. (2013). In Poland, the infections are caused by mainly the PUUV and DOBV serotypes. Hantavirus Infections: What You Need to Know - Healthline The result indicated that through combination, siRNAs could be specifically delivered to the HTNV-infected brain cells and protect against HTNV intracranial infection (Yang et al., 2017). Additionally, RBV was reported to modulate host immune responses by suppressing interleukin-10-producing regulatory T cells (Kobayashi et al., 2012), while there is no evidence showing that ETAR could exert immunoregulatory effects (Szabo, 2017). Aromatic and polar residues spanning the candidate fusion peptide of the. There is currently no antiviral therapy approved for treating hantavirus infection, thus supportive care remains the mainstay of therapy. The subcloned cDNA represented the medium fragment (M; encoding G 1 and G 2 glycoprotein) or small fragment (S; encoding nucleocapsid protein) of SEOV and was cloned into the expression vector WRG 7077. Li Z., Zeng H., Wang Y., Zhang Y., Cheng L., Zhang F., et al. Biological: Andes virus DNA vaccine. Safronetz D., Haddock E., Feldmann F., Ebihara H., Feldmann H. (2011). However, in 2018, the efficacy of iHV on the progression of HFRS did not show a statistically significant protective effect. Rabbits vaccinated with SNV DNA vaccine with muscle electroporation (mEP) produced increased neutralizing antibody titers. China uses approximately 2 million doses of HFRS vaccine every year (Schmaljohn, 2012). (1990). A non-randomized multicentre trial of human immune plasma for treatment of hantavirus cardiopulmonary syndrome caused by. Dysregulation of the beta3 integrin-VEGFR2 complex in. Altered expression and localization of VE-cadherin contributed to impaired barrier structure of adherent junctions, which could lead to incremental cellular permeability (Jiang et al., 2016). On all accounts, novel delivery system should be developed to ensure the stability and selectivity of siRNAs, and the efficacy and safety of these systems remained unclear for the treatment of HFRS or HCPS. Prevention of a hantavirus infection - Canada.ca Recent Approaches in Hantavirus Vaccine Development - Medscape Subunit protein vaccines not only are safe and easy to produce but also do not easily cause interference between the components of a multivalent formulation (Sun et al., 2017; Liang et al., 2018; Qu et al., 2018). Hantavirus Pulmonary Syndrome: Symptoms & Treatment - Cleveland Clinic Notably, there is no reported clinical trial with favipiravir as an antiviral treatment in HFRS and HCPS. Neutralizing antibodies (NAbs) could interact with viral envelope proteins and disturb their binding with receptors on host cells, thus blocking viral attachment. (2016). We also demonstrated that lncRNA NEAT1 could positively regulate RIG-I-DDX60-mediated IFN responses during HTNV infection and that overexpression of NEAT1 could restrain HTNV amplification both in vitro and in vivo. The inactivated vaccines comprise entire virions that are inactivated physically (heat) or chemically. Impact of the Yosemite hantavirus outbreak on hantavirus antibody testing at a national reference laboratory. A study of ANDV hamster model showed that the neutralizing antibody produced by DNA vaccine technology can be used to resist the challenge of an SNV full-length M gene DNA vaccine to prevent the occurrence of HCPS. One case reported that a 37-year-old male who once underwent splenectomy due to congenital spherocytosis manifested with severe capillary leakage syndrome caused by PUUV infection. Inclusion in an NLM database does not imply endorsement of, or agreement with, Antiviral biologic produced in DNA vaccine/goose platform protects hamsters against hantavirus pulmonary syndrome when administered post-exposure. At present, there are currently no US FDA-approved treatments or vaccines available; only the whole virus-inactivated vaccine against HTNV or SEOV is available in China and Korea. We can observe that the annual average number of cases in Shaanxi Province was higher than 2000, ranking at the top of the list (Figure 1). Any medicine, including vaccines, can cause side effects. Modifying the cellular transport of DNA-based vaccines alters the immune response to hantavirus nucleocapsid protein. (1991). Consequently, vaccination for HFRS requires the development of novel, more effective vaccines . In general, the treatment principle for HFRS patients is using intravenous hydration and electrolyte therapy to maintain physiological blood pressure. Characterization of in vitro and in vivo antiviral activity of lactoferrin and ribavirin upon hantavirus. Hantavirus phylogenetic tree on the basis of the M segment sequences. Hantavirus: Symptoms, Treatment, and Prevention - Healthline Subunit protein vaccines not only are safe and easy to produce but also do not easily cause interference between the components of a multivalent formulation (Sun et al., 2017; Liang et al., 2018; Qu et al., 2018). Together, these viruses have annually caused approximately 200,000 human infections worldwide in recent years, with a case fatality rate of 515% for HFRS and up to 40% for HCPS. HTNV/Vero E6 cells/suckling mice/phase II clinical trials, HTNV, PUUV, ANDV/Vero E6 cells/suckling mice (HTNV)/hamsters (ANDV), HTNV, ANDV/Vero E6 cells/suckling mice (HTNV), Pazopanib, dasatinib, PP1, bosutinib, and Src inhibitor 1. 10.23876/j.krcp.18.0044 [PMC free article] . Terajima M., Van Epps H. L., Li D., Leporati A. M., Juhlin S. E., Mustonen J., et al. Currently, there is no approved post-exposure therapeutic countermeasure against hantaviral infection, but diversified treatment strategies have been developed and applied to manage HFRS or HCPS. In 2017, the US CDC investigated an outbreak of SEOV infection that has infected 17 rat owners in seven states (Kerins et al., 2018). The viral entry process is composed of virus attachment or absorption on susceptible cells, penetration and subsequent uncoating, which is the first step for hantaviral life cycle.
