Host gene expression classifiers diagnose acute respiratory illness etiology.
Tsalik, Ephraim L; Henao, Ricardo; Nichols, Marshall; Burke, Thomas; Ko, Emily R; McClain, Micah T; Hudson, Lori L; ... (24 authors) (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. ... -

Potential Cost-effectiveness of Early Identification of Hospital-acquired Infection in Critically Ill Patients.
Tsalik, Ephraim L; Li, Yanhong; Hudson, Lori L; Chu, Vivian H; Himmel, Tiffany; Limkakeng, Alex T; Katz, Jason N; ... (14 authors) (Ann Am Thorac Soc, 2016-03)RATIONALE: Limitations in methods for the rapid diagnosis of hospital-acquired infections often delay initiation of effective antimicrobial therapy. New diagnostic approaches offer potential clinical and cost-related improvements ... -
Previously Derived Host Gene Expression Classifiers Identify Bacterial and Viral Etiologies of Acute Febrile Respiratory Illness in a South Asian Population.
Tillekeratne, L Gayani; Suchindran, Sunil; Ko, Emily R; Petzold, Elizabeth A; Bodinayake, Champica K; Nagahawatte, Ajith; Devasiri, Vasantha; ... (16 authors) (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 ... -
Prospective Validation of a Rapid Host Gene Expression Test to Discriminate Bacterial From Viral Respiratory Infection.
Ko, Emily R; Henao, Ricardo; Frankey, Katherine; Petzold, Elizabeth A; Isner, Pamela D; Jaehne, Anja K; Allen, Nakia; ... (36 authors) (JAMA network open, 2022-04)<h4>Importance</h4>Bacterial and viral causes of acute respiratory illness (ARI) are difficult to clinically distinguish, resulting in the inappropriate use of antibacterial therapy. The use of a host gene expression-based ... -
SARS-CoV-2 reinfection across a spectrum of immunological states.
McKittrick, Justine M; Burke, Thomas W; Petzold, Elizabeth; Sempowski, Gregory D; Denny, Thomas N; Polage, Christopher R; Tsalik, Ephraim L; ... (8 authors) (Health science reports, 2022-07-22)<h4>Purpose</h4>Several cases of symptomatic reinfection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) after full recovery from a prior episode have been reported. As reinfection has become an increasingly ... -
Systematic comparison of published host gene expression signatures for bacterial/viral discrimination.
Bodkin, Nicholas; Ross, Melissa; McClain, Micah T; Ko, Emily R; Woods, Christopher W; Ginsburg, Geoffrey S; Henao, Ricardo; ... (8 authors) (Genome medicine, 2022-02-21)<h4>Background</h4>Measuring host gene expression is a promising diagnostic strategy to discriminate bacterial and viral infections. Multiple signatures of varying size, complexity, and target populations have been described. ... -
Temporal dynamics of host molecular responses differentiate symptomatic and asymptomatic influenza a infection.
Huang, Yongsheng; Zaas, Aimee K; Rao, Arvind; Dobigeon, Nicolas; Woolf, Peter J; Veldman, Timothy; Øien, N Christine; ... (16 authors) (PLoS Genet, 2011-08)Exposure to influenza viruses is necessary, but not sufficient, for healthy human hosts to develop symptomatic illness. The host response is an important determinant of disease progression. In order to delineate host molecular ... -
The Host Response to Viral Infections Reveals Common and Virus-Specific Signatures in the Peripheral Blood.
Tsalik, Ephraim L; Fiorino, Cassandra; Aqeel, Ammara; Liu, Yiling; Henao, Ricardo; Ko, Emily R; Burke, Thomas W; ... (18 authors) (Frontiers in immunology, 2021-01)Viruses cause a wide spectrum of clinical disease, the majority being acute respiratory infections (ARI). In most cases, ARI symptoms are similar for different viruses although severity can be variable. The objective of ... -
