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 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 ... -
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>... -
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 ... -
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 ... -
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 ... -
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 ... -
Nasopharyngeal Protein Biomarkers of Acute Respiratory Virus Infection.
(EBioMedicine, 2017-03)Infection of respiratory mucosa with viral pathogens triggers complex immunologic events in the affected host. We sought to characterize this response through proteomic analysis of nasopharyngeal lavage in human subjects ... -
Previously Derived Host Gene Expression Classifiers Identify Bacterial and Viral Etiologies of Acute Febrile Respiratory Illness in a South Asian Population.
(Open forum infectious diseases, 2020-06)Background:Pathogen-based diagnostics for acute respiratory infection (ARI) have limited ability to detect etiology of illness. We previously showed that peripheral blood-based host gene expression classifiers accurately ... -
Transcriptomic Analysis of the Host Response and Innate Resilience to Enterotoxigenic Escherichia coli Infection in Humans.
(J Infect Dis, 2016-05-01)BACKGROUND: Enterotoxigenic Escherichia coli (ETEC) is a globally prevalent cause of diarrhea. Though usually self-limited, it can be severe and debilitating. Little is known about the host transcriptional response to infection. ... -
Validation of a host response test to distinguish bacterial and viral respiratory infection.
(EBioMedicine, 2019-10-17)BACKGROUND:Distinguishing bacterial and viral respiratory infections is challenging. Novel diagnostics based on differential host gene expression patterns are promising but have not been translated to a clinical platform ...
