IP-10 as a blood biomarker of respiratory failure

Tech ID: T-019671

Technology Description

Researchers in Philip Mudd’s lab at Washington University have developed a blood biomarker test that detects impending respiratory failure before existing diagnostics. High levels of the biomarker IP-10 in the blood are correlated with the subsequent development of acute respiratory disease syndrome (ARDS) in patients with severe viral pneumonia.

Current clinical tools can detect ARDS as it is occurring but not early enough to intervene with preventative measures. Other cytokines have been correlated with ARDS, but their measurement requires a bronchoalveolar lavage (BAL) instead of a blood test.

(Left) IP-10 levels in patient BAL samples correlated with more severe viral pneumonia. (Middle) IP-10 levels in plasma within 48 hours of hospital admission correlated with organ dysfunction and death. (Right) IP-10 levels in plasma and BAL were correlated.

Stage of Research

The researchers identified IP-10 levels in the blood as a potential biomarker for ARDS in a cohort of 17 patients with severe viral pneumonia. The biomarker was then validated in a separate cohort of 168 patients with COVID-19, where it predicted organ dysfunction, intubation and death.
