Exploring The Possible Phenomenon Of Viral Interference Between The Novel Coronavirus And Common Respiratory Viruses, Spencer Deleveaux, Alexandria Clarke-Kregor, Xavier Fonseca-Fuentes, Essam Mekhaiel

Journal of Patient-Centered Research and Reviews

At the peak of the 2021 wave of the SARS-CoV-2 alpha variant in North America, there was concern for a superimposed wave of viral respiratory infections. There was, however, an apparent shift in the usual epidemiology of these pathogens, especially during the traditional influenza season from approximately October 2020 to March 2021. This article seeks to briefly describe the epidemiology of notable respiratory pathogens during the first wave of the COVID-19 pandemic and to focus on one possible factor for the trends observed. There are many contributory elements to the observed viral trends, but in particular, we present a synopsis …

Potential Of Dietary Flavonoids In The Prevention And Therapy Of Covid-19 : Focusing In Mast Cell - Calcium Ion Channel Axis, Aryo Tedjo

Indonesian Journal of Medical Chemistry and Bioinformatics

Syndrome Acute Respiratory Syndrome Corona Virus-2 (SARS COV2) is the virus that causes the COVID19 disease and has caused more than 4 million deaths worldwide. This virus infects the host cell through the interaction between the virus’s glycoprotein S molecule with the ACE2 which is the virus receptor, binding, undergoes membrane fusion and enters the cell and replicates in it. Currently, several strategies used in developing anti-viral compounds are targeting compounds that play a role in the process of entering the virus into host cells such as ACE2, S glycoprotein, and TMPRSS2, while some target main proteases such as RNA …

Performance Of A Sars-Cov-2 Rt-Pcr Assay With Non-Traditional Specimen Types, Subathra Marimuthu, Holly Aliesky, Heather Ness, Daniya Sheikh, Sathya Rashmit, Dawn Balcom, Leslie A. Wolf

The University of Louisville Journal of Respiratory Infections

During the first two years of the coronavirus disease 2019 (COVID-19) pandemic, nasopharyngeal (NP) specimens were the gold standard for clinical diagnostic testing. As information about the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causing the pandemic continued to be shared, it was clear that the virus could be detected in other specimen types during an active infection. The University of Louisville Infectious Diseases Laboratory accepted non-traditional specimen types, most without a paired, positive NP result, for research purposes only to support local epidemiology efforts. A real-time reverse transcription-polymerase chain reaction (RT-PCR) assay originally validated for NP specimens was used …

Endogenous Mirna-Based Innate-Immunity Against Sars-Cov-2 Invasion Of The Brain, Walter J. Lukiw, Aileen I. Pogue

School of Medicine Faculty Publications

The severe acute respiratory syndrome Coronavirus-2 (SARS-CoV-2), the causative agent of COVID-19, possesses an unusually large positive-sense, single-stranded viral RNA (ssvRNA) genome of about ~29,903 nucleotides (nt). In many respects, this ssvRNA resembles a very large, polycistronic messenger RNA (mRNA) possessing a 5′-methyl cap (m7GpppN), a 3′- and 5′-untranslated region (3′-UTR, 5′-UTR), and a poly-adenylated (poly-A+) tail. As such, the SARS-CoV-2 ssvRNA is susceptible to targeting by small non-coding RNA (sncRNA) and/or microRNA (miRNA), as well as neutralization and/or inhibition of its infectivity via the human body’s natural complement of about ~2650 miRNA species. Depending on host cell and tissue …

Implementation Of Mrsa Nasal Swabs As An Antimicrobial Stewardship Intervention To Decrease Anti-Mrsa Therapy In Covid-19 Infection, Alaina Dekerlegand, Emily Johnston, Britney Mellor, Melanie Rae Schrack, Catherine O’Neal

School of Medicine Faculty Publications

In the early stages of treating patients with SARS-CoV-2, limited information was available to guide antimicrobial stewardship interventions. The COVID-19 Task Force and Antimicrobial Stewardship Committee, at a 988-bed academic medical center, implemented the use of methicillin-resistant Staphylococcus aureus (MRSA) nasal swab polymerase chain reaction (PCR) testing to assist with the de-escalation of anti-MRSA therapy in patients with suspected superimposed bacterial pneumonia in COVID-19. A retrospective study was conducted to evaluate the impact of MRSA nasal swab PCR testing on the rate of anti-MRSA therapy between 13 April 2020 and 26 July 2020. A total of 122 patients were included …

A Case Of Pleural Tuberculosis Vs Latent Tuberculosis Reactivation As A Result Of Covid-19 Infection And Treatment, Wesley Tang, Lex Leonhardt, Aamir Pervez, Satish Sarvepalli

Journal of Community Hospital Internal Medicine Perspectives

The reactivation of latent tuberculosis occurs when a patient living with Mycobacterium tuberculosis enters a state where the immune system is suppressed. Since early 2021, the standard of care has been to provide corticosteroids in patients with COVID-19 infection in hospitalized patients receiving supplemental oxygen or mechanical ventilation. The immunomodulatory effects of corticosteroids are potentially detrimental for patients with latent vs active tuberculosis, with concomitant SARS-CoV2 infection. We present one of the first few cases in the literature detailing a case of reactivation of latent tuberculosis vs. pleural tuberculosis as a consequence of COVID-19, and who underwent subsequent corticosteroid treatment.

Gain-Of-Signal Assays For Probing Inhibition Of Sars-Cov-2 Mpro/3clpro In Living Cells, Seyed Arad Moghadasi, Morgan A Esler, Yuka Otsuka, Jordan T Becker, Sofia N Moraes, Constance B Anderson, Srinivas Chamakuri, Christopher Belica, Chloe Wick, Daniel A Harki, Damian W Young, Louis Scampavia, Timothy P Spicer, Ke Shi, Hideki Aihara, William L Brown, Reuben S Harris

Faculty, Staff and Students Publications

The main protease, Mpro, of SARS-CoV-2 is required to cleave the viral polyprotein into precise functional units for virus replication and pathogenesis. Here, we report quantitative reporters for Mpro function in living cells in which protease inhibition by genetic or chemical methods results in robust signal readouts by fluorescence (enhanced green fluorescent protein [eGFP]) or bioluminescence (firefly luciferase). These gain-of-signal systems are scalable to high-throughput platforms for quantitative discrimination between Mpro mutants and/or inhibitor potencies as evidenced by validation of several reported inhibitors. Additional utility is shown by single Mpro amino acid variants and structural information combining to demonstrate that …

Covid-19 Case Complicated With Organizing Pneumonia And Pneumothorax: A Case Report, Tammy E. Phillips, Hammad A. Bhatti, Minh Q. Ho

The University of Louisville Journal of Respiratory Infections

Organizing pneumonia can be idiopathic or caused by multiple etiologies, including viral or bacterial pneumonia, drugs, and autoimmune disorders. It can rarely lead to cyst formation and pneumothorax with the exact mechanism remaining unclear. This case presents a previously healthy 50-year-old male who contracted COVID-19 with subsequent development of organizing pneumonia and pneumothorax. Patients presenting with hypoxic respiratory failure due to COVID-19 should be screened for organizing pneumonia upon discharge. This case also illustrates the importance of following such patients radiologically to monitor interstitial lung disease and consider pneumothorax for patients re-presenting with acute symptoms.
