Metabolomic and immunological signatures of asthma severity in children.

ABSTRACT:

Background

Multiple risk factors for asthma severity have been identified by epidemiological studies. Yet, the pathophysiological mechanisms driving the severity of clinical asthma manifestations remain incompletely understood. In asthmatic children, Notch4 expression on circulating Treg cells and levels of circulating GDF15 have been shown to be increased as a function of disease severity, suggesting a contribution of Treg dysfunction to disease phenotype.

Methods

126 children with asthma (intermittent = 40; mild persistent = 43; moderate persistent = 29, and severe persistent = 14) and 83 non-asthmatic controls were recruited in the Allergy clinic at Boston Children's Hospital and from asthma cohorts. Untargeted metabolomic analysis and cytokine profiling were performed in
