Beckman Coulter, global leader in advanced diagnostics, today announced that it will partner with Massachusetts General Hospital to validate the use of the novel Monocyte Distribution Width (MDW) hematology biomarker in rapid identification of children presenting with early signs of severe illness from infection.
BREA, CALIF., July 25, 2022 — This pivotal, multi-center trial will receive funding from the Biomedical Advanced Research and Development Authority (BARDA), part of the office of the Assistant Secretary for Preparedness and Response at the U.S. Department of Health and Human Services. MDW is currently the only FDA-cleared blood biomarker to aid in detecting adult sepsis in the Emergency Department (ED). This current partnership aims to expand the utility of MDW as a screening tool to measure the severity of infection in children 17 years old and younger presenting with high fevers.
Over 25 million children under 17 visit the emergency room every year, and about one in five presents with a fever.1 The most common cause of fever in these children is infections that can be safely treated at home; however, one out of every four pediatric hospital admissions are due to complications from infection.2 No objective biomarker yet exists that accurately identifies children at risk of hospitalization from an excessive immune response early in the infectious course when intervention is critical, making clinical decisions in the ED on how to treat pediatric infections difficult.
“A sick, febrile child can be challenging to examine, and current blood tests have limited ability to predict who will progress to acute illness,” states Lael Yonker, M.D., a pediatric pulmonologist at Mass General for Children, and co-investigator on this clinical trial. “Objective tests that are readily available are needed to make sure children get the medical attention they need in a timely manner.”
The utility of MDW as a biomarker in pediatric infection was first recognized by Mass General during the height of the COVID-19 pandemic, when more than 400 children a month were developing a life-threatening complication from COVID-19, now termed Multisystem Inflammatory Syndrome in Children (MIS-C).
As published in June 2022 in BMC Infectious Diseases3, the team found that MDW can improve the identification of children at high risk of MIS-C complication, a task that has proven challenging to clinicians.4 Now, this team will join Beckman Coulter and BARDA to potentially expand the use of MDW in the early recognition of severe infections in children presenting to EDs.
MDW is a regulatory-cleared parameter for adult patients presenting to the ED and is available as a standard component of a CBC performed on Beckman Coulter’s DxH 900 and 690T hematology analyzers. The MDW parameter measures the dispersion of monocyte volume in the blood, which is altered during infection due to monocyte activation and subsequent changes in monocyte morphology. Increases in MDW indicate increases in the variability of monocyte morphology, which can indicate a progression from localized to systemic infection.
MDW provides physicians with an early indication of sepsis risk, which is especially important when a patient’s symptoms are mild and alternative diagnoses are being considered. MDW is only available on Beckman Coulter platforms.
This project has been funded in whole or in part with federal funds from the Department of Health and Human Services; Office of the Assistant Secretary for Preparedness and Response; Biomedical Advanced Research and Development Authority, under contract number 75A50122C00036.
