A blood-based host gene expression assay for early detection of respiratory viral infection: an index-cluster prospective cohort study.
(The Lancet. Infectious diseases, 2020-09-24)BACKGROUND:Early and accurate identification of individuals with viral infections is crucial for clinical management and public health interventions. We aimed to assess the ability of transcriptomic biomarkers to identify ... -
A comparison of host response strategies to distinguish bacterial and viral infection.
(PloS one, 2021-01)<h4>Objectives</h4>Compare three host response strategies to distinguish bacterial and viral etiologies of acute respiratory illness (ARI).<h4>Methods</h4>In this observational cohort study, procalcitonin, a 3-protein panel ... -
A crowdsourced analysis to identify ab initio molecular signatures predictive of susceptibility to viral infection.
(Nature communications, 2018-10-24)The response to respiratory viruses varies substantially between individuals, and there are currently no known molecular predictors from the early stages of infection. Here we conduct a community-based analysis to determine ... -
A Genomic Signature of Influenza Infection Shows Potential for Presymptomatic Detection, Guiding Early Therapy, and Monitoring Clinical Responses.
(Open Forum Infect Dis, 2016-01)Early, presymptomatic intervention with oseltamivir (corresponding to the onset of a published host-based genomic signature of influenza infection) resulted in decreased overall influenza symptoms (aggregate symptom scores ... -
A host gene expression approach for identifying triggers of asthma exacerbations.
(PloS one, 2019-01)RATIONALE:Asthma exacerbations often occur due to infectious triggers, but determining whether infection is present and whether it is bacterial or viral remains clinically challenging. A diagnostic strategy that clarifies ... -
A host transcriptional signature for presymptomatic detection of infection in humans exposed to influenza H1N1 or H3N2.
(PLoS One, 2013)There is great potential for host-based gene expression analysis to impact the early diagnosis of infectious diseases. In particular, the influenza pandemic of 2009 highlighted the challenges and limitations of traditional ... -
A miRNA Host Response Signature Accurately Discriminates Acute Respiratory Infection Etiologies.
(Frontiers in microbiology, 2018-01)Background: Acute respiratory infections (ARIs) are the leading indication for antibacterial prescriptions despite a viral etiology in the majority of cases. The lack of available diagnostics to discriminate viral and bacterial ... -
An integrated transcriptome and expressed variant analysis of sepsis survival and death.
(Genome Med, 2014)BACKGROUND: Sepsis, a leading cause of morbidity and mortality, is not a homogeneous disease but rather a syndrome encompassing many heterogeneous pathophysiologies. Patient factors including genetics predispose to poor ... -
Assessment of the Feasibility of Using Noninvasive Wearable Biometric Monitoring Sensors to Detect Influenza and the Common Cold Before Symptom Onset.
(JAMA network open, 2021-09)<h4>Importance</h4>Currently, there are no presymptomatic screening methods to identify individuals infected with a respiratory virus to prevent disease spread and to predict their trajectory for resource allocation.<h4>... -
Blood RNA alternative splicing events as diagnostic biomarkers for infectious disease
(Cell Reports Methods, 2023-01-01)Assays detecting blood transcriptome changes are studied for infectious disease diagnosis. Blood-based RNA alternative splicing (AS) events, which have not been well characterized in pathogen infection, have potential ... -
Chromatin remodeling in peripheral blood cells reflects COVID-19 symptom severity.
(bioRxiv, 2020-12-05)SARS-CoV-2 infection triggers highly variable host responses and causes varying degrees of illness in humans. We sought to harness the peripheral blood mononuclear cell (PBMC) response over the course of illness to provide ... -
Comparing the Diagnostic Accuracy of Clinician Judgment to a Novel Host Response Diagnostic for Acute Respiratory Illness.
(Open forum infectious diseases, 2021-12)<h4>Background</h4>Difficulty discriminating bacterial from viral infections drives antibacterial misuse. Host gene expression tests discriminate bacterial and viral etiologies, but their clinical utility has not ... -
Differential chromatin accessibility in peripheral blood mononuclear cells underlies COVID-19 disease severity prior to seroconversion.
(Res Sq, 2022-04-07)SARS-CoV-2 infection triggers profound and variable immune responses in human hosts. Chromatin remodeling has been observed in individuals severely ill or convalescing with COVID-19, but chromatin remodeling early in disease ... -
Differential chromatin accessibility in peripheral blood mononuclear cells underlies COVID-19 disease severity prior to seroconversion.
(Scientific reports, 2022-07-09)SARS-CoV-2 infection triggers profound and variable immune responses in human hosts. Chromatin remodeling has been observed in individuals severely ill or convalescing with COVID-19, but chromatin remodeling early in disease ... -
Discriminating Bacterial and Viral Infection Using a Rapid Host Gene Expression Test.
(Critical care medicine, 2021-10)<h4>Objectives</h4>Host gene expression signatures discriminate bacterial and viral infection but have not been translated to a clinical test platform. This study enrolled an independent cohort of patients to describe and ... -
Dysregulated transcriptional responses to SARS-CoV-2 in the periphery support novel diagnostic approaches.
(medRxiv, 2020-07-26)In order to elucidate novel aspects of the host response to SARS-CoV-2 we performed RNA sequencing on peripheral blood samples across 77 timepoints from 46 subjects with COVID-19 and compared them to subjects with seasonal ... -
Dysregulated transcriptional responses to SARS-CoV-2 in the periphery.
(Nature communications, 2021-02-17)SARS-CoV-2 infection has been shown to trigger a wide spectrum of immune responses and clinical manifestations in human hosts. Here, we sought to elucidate novel aspects of the host response to SARS-CoV-2 infection through ... -
H3N2 influenza infection elicits more cross-reactive and less clonally expanded anti-hemagglutinin antibodies than influenza vaccination.
(PloS one, 2011-01)During the recent H1N1 influenza pandemic, excess morbidity and mortality was seen in young but not older adults suggesting that prior infection with influenza strains may have protected older subjects. In contrast, a history ... -
Host gene expression classifiers diagnose acute respiratory illness etiology.
(Sci Transl Med, 2016-01-20)Acute respiratory infections caused by bacterial or viral pathogens are among the most common reasons for seeking medical care. Despite improvements in pathogen-based diagnostics, most patients receive inappropriate antibiotics. ... -
Mucosal Associated Invariant T (MAIT) Cell Responses Differ by Sex in COVID-19.
(Med (New York, N.Y.), 2021-04-13)Sexual dimorphisms in immune responses contribute to coronavirus disease 2019 (COVID-19) outcomes, yet the mechanisms governing this disparity remain incompletely understood. We carried out sex-balanced sampling of peripheral ...
