For International ME/CFS Awareness Day, we would like to announce the official publication of a large metabolomics study from our Center. The work led by Arnaud Germain, PhD, describes results from a longitudinal plasma metabolite study associated with a 2-day cardiopulmonary exercise test (CPET). Over 100 individuals, including both females and males, were assayed before and after both days of the 2-day CPET. The article is open access in the journal JCI Insight. The quote below, from this publication, does an excellent job at summarizing the study.

Our longitudinal study design has allowed us to identify a number of pathways that diverge between healthy individuals and those with ME/CFS 24 hours after an exercise challenge, at which time patients typically experience PEM. Inability to recover properly after exertion is one of the most disabling symptoms of ME/CFS. Our study provides insight into the metabolic changes that are inimical to proper response to physical effort.
