Abstract:
|
Dengue virus is the most widespread arthropod-borne virus affecting humans, with as many as 390 million infections and 96 million cases globally each year. Of particular concern are the subset of cases which progress to life-threatening dengue hemorrhagic fever/ dengue shock syndrome. A tool that quickly and accurately differentiates dengue from other viral infections and is prognostic of progression to severe disease would be of great use for ensuring timely fluid intervention and supportive care, especially if it is low-cost and non-invasive. To assist with developing such a tool, we use liquid chromatography-mass spectrometry (LC-MS) to detect tens of thousands of molecular features in serum, saliva, and urine of suspected dengue patients in Nicaragua. We then use machine-learning techniques to identify small molecule biomarkers which, combined with routinely obtained clinical data, predict dengue diagnosis and prognosis.
