This post covers Zahoor and colleagues' 2021 review in Cellular and Molecular Life Sciences, which surveys metabolomics studies in multiple sclerosis across cerebrospinal fluid, blood, urine, tears, and the EAE model. It focuses on what the assembled tables reveal rather than individual findings: the same metabolites reported in opposite directions in the same fluid, the small sample sizes behind most studies, the finding that the animal model and human patients share only creatinine among altered metabolites, and the two instances where the approach has produced something testable, resolvin D1 and bile acid supplementation. It closes on the review's own recommendations and on what a narrative review without effect sizes cannot settle.
