Abstract
In continuation of our previous effort, different in silico selection methods were applied to 310 naturally isolated metabolites that exhibited antiviral potentialities before. The applied selection methods aimed to pick the most relevant inhibitor of SARS-CoV-2 nsp10. At first, a structural similarity study against the co-crystallized ligand, S-Adenosyl Methionine (SAM), of SARS-CoV-2 nonstructural protein (nsp10) (PDB ID: 6W4H) was carried out. The similarity analysis culled 30 candidates. Secondly, a fingerprint study against SAM preferred compounds 44, 48, 85, 102, 105, 182, 220, 221, 282, 284, 285, 301, and 302. The docking studies picked 48, 182, 220, 221, and 284. While the ADMET analysis expected the likeness of the five candidates to be drugs, the toxicity study preferred compounds 48 and 182. Finally, a density-functional theory (DFT) study suggested vidarabine (182) to be the most relevant SARS-Cov-2 nsp10 inhibitor.

Shiraki K, Daikoku T. Favipiravir, an anti-influenza drug against life-threatening RNA virus infections. Pharmacol Ther 2020; 209:107512. [PMID: 32097670 PMCID: PMC7102570 DOI: 10.1016/j.pharmthera.2020.107512] [Citation(s) in RCA: 292] [Impact Index Per Article: 73.0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2019] [Accepted: 02/14/2020] [Indexed: 12/16/2022]
Abstract
Favipiravir has been developed as an anti-influenza drug and licensed as an anti-influenza drug in Japan. Additionally, favipiravir is being stockpiled for 2 million people as a countermeasure for novel influenza strains. This drug functions as a chain terminator at the site of incorporation of the viral RNA and reduces the viral load. Favipiravir cures all mice in a lethal influenza infection model, while oseltamivir fails to cure the animals. Thus, favipiravir contributes to curing animals with lethal infection. In addition to influenza, favipiravir has a broad spectrum of anti-RNA virus activities in vitro and efficacies in animal models with lethal RNA viruses and has been used for treatment of human infection with life-threatening Ebola virus, Lassa virus, rabies, and severe fever with thrombocytopenia syndrome. The best feature of favipiravir as an antiviral agent is the apparent lack of generation of favipiravir-resistant viruses. Favipiravir alone maintains its therapeutic efficacy from the first to the last patient in an influenza pandemic or an epidemic lethal RNA virus infection. Favipiravir is expected to be an important therapeutic agent for severe influenza, the next pandemic influenza strain, and other severe RNA virus infections for which standard treatments are not available.

Abstract
Human adenoviruses (HAdV) are the cause of many acute infections, mostly in the respiratory and gastrointestinal (GI) tracts, as well as conjunctivitis. HAdV diseases in immunocompetent individuals are mostly self-limiting; however, in immunocompromised individuals, especially in pediatric units, HAdV infections are the cause of high morbidity and mortality. Despite the significant clinical impact, there are currently no approved antiviral therapies for HAdV infections. Here, we provide an overview of the different targets that could be considered for the design of specific drugs against HAdV, as well as the available in vitro and in vivo tools for the screening and evaluation of candidate molecules.

Abstract
Viral infections are an important complication of transplantation. Polyomavirus are the commonest viruses that infect the renal allograft. Herpes virus nephropathy has also been described. In the past 15 years, adenovirus nephritis has emerged as a potentially life-threatening disease in renal transplant patients in developed countries. Most of the papers devoted to adenovirus nephritis are reported cases. The fate of such patients in resources-limited countries is not known. Herein, we describe the clinical, biological and prognostic findings of a black African transplanted patient with adenoviral hemorrhagic cystitis. This case is the very first of its kind reported in black Africa in a setting of a start of a renal transplantation pilot project. The patient is a 54-year-old man admitted at the nephrology service for gross haematuria and fever occurred 1 month after kidney transplantation. The diagnosis of adenoviral hemorrhagic cystitis has been suspected because the patient has displayed recurrent conjunctivitis and gastroenteritis well before transplantation, which was then confirmed by the real-time polymerase chain reaction performed on the blood. Conservatory measures associated with immunosuppression reduction have permitted the discontinuation of haematuria. This case has been discussed in regard of the epidemiology, the diagnosis, the treatment, the evolution and the prognosis of the adenoviral infection in the renal transplant patient. A review of the literature has been performed subsequently.

Abstract
Human adenoviruses function as genetic models and vectors for gene therapy. Upper respiratory, gastrointestinal or ocular infections usually have mild course without any major complication in immunocompetent individuals. However, reactivation from latency in immunocompromised patients may lead to death. Depending on the underlying diseases, different adenovirus serotypes damage different organs. In children with severe combined immunodeficiency syndrome, serotypes of species A and C induce lung, liver or bladder inflammation. Paediatric hematopoietic stem cell transplantation is frequently followed by serotype 31-induced pneumonia, enteritis, cystitis. B serotypes can destroy transplanted organs. In AIDS patients, D and novel F serotypes cause enteritis. Recombinants of B serotypes induce urinary tract infections. Progression of lymphomas, tumours, and systemic lupus erythematosus might be facilitated by immunosuppressive effects of adenoviruses. As far as the diagnostic work-up of adenoviruses, detection of viral DNA and virus copy number is predictive, while serology testing is quite unreliable. For treatment, cidofovir derivates, ribavirin, ganciclovir, vidarabine and microRNA have been used.

Abstract
HC is a complication associated with HSCT, but occurs rarely in solid organ recipients. The reported incidence varies from <10% to more than 70%. HC is characterized by hemorrhagic inflammation in urinary tract mucosa with symptoms varying from asymptomatic microscopic hematuria to frank hematuria with clot formation and urinary tract obstruction. Early onset HC may be explained by toxicity of chemo- and/or radiotherapy, while multiple factors including viral infections and their interplay seem to be involved in late onset HC. So far, only incidence of cyclophosphamide-associated HC has been reduced with preventive treatment. Likely, once HC is established, the treatment principles are similar regardless of the etiology and depend on the intensity of HC. Prevention of urinary tract obstruction, transfusion support, analgesic, and spasmolytic therapy are generally accepted in HC management. Treatment beyond this conservative approach entails higher risk for side effects, and thus treatment escalation proportional to HC intensity is warranted. No standard and evidence-based treatment escalation algorithm has been widely adopted yet. As severe HC following HSCT is a potentially life-threatening complication, a multidisciplinary and individual approach is required in children suffering from this devastating complication.

Neutralizing anti-gH antibody of Varicella-zoster virus modulates distribution of gH and induces gene regulation, mimicking latency. J Virol 2011; 85:8172-80.

Abstract
The anti-glycoprotein H (gH) monoclonal antibody (anti-gH-MAb) that neutralizes varicella-zoster virus (VZV) inhibited cell-to-cell infection, resulting in a single infected cell without apoptosis or necrosis, and the number of infectious cells in cultures treated with anti-gH-MAb declined to undetectable levels in 7 to 10 days. Anti-gH-MAb modulated the wide cytoplasmic distribution of gH colocalized with glycoprotein E (gE) to the cytoplasmic compartment with endoplasmic reticulum (ER) and Golgi markers near the nucleus, while gE retained its cytoplasmic distribution. Thus, the disintegrated distribution of gH and gE caused the loss of cellular infectivity. After 4 weeks of treatment with anti-gH-MAb, no infectious virus was recovered, even after cultivation without anti-gH-MAb for another 8 weeks or various other treatments. Cells were infected with Oka varicella vaccine expressing hepatitis B surface antigen (ROka) and treated with anti-gH-MAb for 4 weeks, and ROka was recovered from the quiescently infected cells by superinfection with the parent Oka vaccine. Among the genes 21, 29, 62, 63, and 66, transcripts of gene 63 were the most frequently detected, and products from the genes 63 and 62, but not gE, were detected mainly in the cytoplasm of quiescently infected cells, in contrast to their nuclear localization in lytically infected cells. The patterns of transcripts and products from the quiescently infected cells were similar to those of latent VZV in human ganglia. Thus, anti-gH-MAb treatment resulted in the antigenic modulation and dormancy of infectivity of VZV. Antigenic modulation by anti-gH-MAb illuminates a new aspect in pathogenesis in VZV infection and the gene regulation of VZV during latency in human ganglia.

Abstract
Background The association between baseline seropositivity to human adenovirus (HAdV) type 5 and increased HIV acquisition in the Step HIV Vaccine Study has raised questions concerning frequency of acquired and/or persistent Adenovirus infections among adults at high risk of HIV-1 infection. Methodology To evaluate the frequency and pattern of HAdV shedding from the lower GI tract, we retrospectively tested rectal swabs for HAdVs in a cohort of 20 HSV-2 positive HIV-positive Peruvian men who have sex with men (MSM) undergoing rectal swabbing three times/week for 18 consecutive weeks, in a prospective study of HSV-2 suppression in HIV infection. Viral DNA was extracted and amplified using a sensitive multiplex PCR assay that detects all currently recognized HAdV types. Molecular typing of viruses was performed on selected samples by hexon gene sequencing. Baseline neutralizing antibody titers to HAdVs −5, −26, −35 and −48 were also assessed. Principal Findings 15/20 individuals had HAdV detected during follow up. The median frequency of HAdV detection was 30% of samples (range 2.0% to 64.7%). HAdV shedding typically occurred on consecutive days in clustered episodes lasting a median of 4 days (range 1 to 9 days) separated by periods without shedding, suggesting frequent new infections or reactivation of latent infections over time. 8 of the 15 shedders had more than one type detected in follow-up. 20 HAdV types from species B, C, and D were identified, including HAdV-5, −26 and −48, HAdV types under development as potential vaccine candidates. 14/20 subjects were seropositive for HAdV-5; 15/20 for HAdV-26; 3/20 for HAdV-35; and 2/20 for HAdV-48. HAdV shedding did not correlate with CD4 count, plasma HIV-1 viral load, or titers to HAdV-5 or HAdV-35. The sole individual with HAdV-5 shedding was HAdV-5 seropositive. Conclusions HAdV shedding was highly prevalent and diverse, including types presently under consideration as HIV vaccine vectors. Subclinical HAdV infection of the GI tract is common among MSM in Peru; the prevalence of HAdV in the enteric tract should be evaluated in other populations. The association between ongoing recent enteric HAdV and the immune response to recombinant HAdV vaccines should be evaluated.

Abstract
Viruses are important pathogens causing respiratory tract infections both in the community and health-care facility settings. They are extremely common causes of morbidity in the competent hosts and some are associated with significant mortality in the compromised individuals. With wider application of molecular techniques, novel viruses are being described and old viruses are found to have new significance in different epidemiological and clinical settings. Some of these emerging pathogens may have the potential to cause pandemics or global spread of a severe disease, as exemplified by severe acute respiratory syndrome and avian influenza. Antiviral therapy of viral respiratory infections is often unnecessary in the competent hosts because most of them are selflimiting and effective agents are not always available. In the immunocompromised individuals or for infections caused by highly pathogenic viruses, such as avian influenza viruses (AIV), antiviral treatment is highly desirable, despite the fact that many of the agents may not have undergone stringent clinical trials. In immunocompetent hosts, antiviral therapy can be stopped early because adaptive immune response can usually be mounted within 5-14 days. However, the duration of antiviral therapy in immunosuppressed hosts depends on clinical and radiological resolution, the degree and duration of immunosuppression, and therefore maintenance therapy is sometimes needed after the initial response. Immunotherapy and immunoprophylaxis appear to be promising directions for future research. Appropriate and targeted immunomodulation may play an important adjunctive role in some of these infections by limiting the extent of end-organ damage and multi-organ failure in some fulminant infections.

Abstract
Lower urinary tract infections (UTIs) are common among the general population and are most often caused by bacterial pathogens. Viruses are an uncommon cause of UTIs in an immunocompetent host; however, viruses are increasingly recognized as the cause of lower UTI, especially hemorrhagic cystitis, among immunocompromised patients. BK virus, adenovirus, and cytomegalovirus are predominant pathogens involved in hemorrhagic cystitis after stem cell and solid organ transplantation, and their early diagnosis and treatment may prevent significant morbidity of hemorrhagic cystitis. The diagnosis of viral lower UTI is based on molecular techniques, and real-time polymerase chain reaction is often the method of choice because it allows for quantification of viral load. Cidofovir is becoming a drug of choice in viral UTIs because it is active against the most common viral pathogens. This review discusses the epidemiology, pitfalls in diagnosis, and current treatment of viral UTIs.

Abstract
Hepatitis is caused by hepatitis viruses, but hepatitis or hepatocellular enzyme abnormalities is sometimes associated with infection by the hepatiticomimetic viruses. The direct and indirect effects of infection with hepatiticomimetic viruses were examined in two human hepatocyte systems. Poliovirus, adenovirus, and herpes simplex virus (HSV) induced cytopathology in Hep G2 cells. Measles virus caused no change in hepatocytes. Poliovirus infection did not affect cellular protein synthesis, and the peak of hepatocellular enzyme release coincided with the peak of virus release. The increase in adenovirus protein synthesis correlated with the decrease of transferrin synthesis, and enzyme release was not prominent. HSV induced viral protein synthesis with enhanced processing and inhibition of synthesis of alpha1-antitrypsin. The peak of enzyme release was later than the peak of virus release. In primary hepatocytes, poliovirus, adenovirus, and induced extensive cytopathology and enzyme release, and VZV caused cytopathology and significant but minute enzyme release. The ratio of lactate dehydrogenase to aspartate aminotransferase release was larger in poliovirus infection in both hepatocytes than in HSV or VZV infection. Although poliovirus and adenovirus are released by cytolysis and HSV and VZV are secreted by exocytosis of cytoplasmic vacuoles, enzyme release was independent of the type of virus release. Adenovirus showed strong cytotoxicity but did not modify the membrane nor cause enzyme release. Enzyme release was associated with modification of the surface membrane due to apoptosis with poliovirus and necrosis with HSV. Consequently hepatocellular injury by viral infection did not reflect the amount or pattern of hepatocellular enzyme release.

Abstract
A wide range of viruses affect the respiratory tract of transplant recipients, including adenovirus, influenza, human metapneumovirus, parainfluenza virus, respiratory syncytial virus (RSV) and rhinovirus. Prospective studies using contemporary diagnostic techniques have recently improved our understanding of the epidemiology and importance of these respiratory viruses among transplant recipients. From these studies, rhinovirus, in particular, has been shown to be one of the most common causes of infection in stem cell and lung transplant recipients. In addition to epidemiological data, recent studies have also advanced our understanding of management of influenza, adenovirus, and RSV infections among transplant recipients.

Clinical presentations range from asymptomatic viremia to respiratory and gastrointestinal disease, hemorrhagic cystitis, and severe disseminated illness. The limited clinical data available support the use of cidofovir for many of these illnesses. Prospective studies are needed to better understand the pathogenesis of and therapeutic options for adenoviral infections in this patient population.
