Tea-Time at Simmaron I: Mady Hornig on the "Peterson Subsets", Immune Exhaustion and New Gut Findings In ME/CFS

In her presentation, Dr. Hornig first reviewed the recent finding from the Chronic Fatigue Initiative-funded study run by the Columbia team: massive immune up regulation in short duration ME/CFS patients and immune down regulation in longer duration ME/CFS patients.  The same immune factors, interestingly enough, that were upregulated early in the illness were squashed later in the illness. One key viral fighter called IFN-y that was hugely important in early ME/CFS but significantly down regulated in later ME/CFS pointed an arrow at a process called “immune exhaustion”.



Columbia’s Center for Infection and Immunity has  completed the testing of samples from 50 patients and 50 healthy controls started in the CFI study and extended in an NIH-funded study to analyze ME/CFS microbiome. They are completing analysis of the samples now.

They’re finding evidence of significant changes in the gut flora of ME/CFS patients vs healthy controls. For one, altered levels of butyrate producing bacteria have been found in the ME/CFS patients. Noting that similar differences have been found in autoimmune diseases, Dr. Hornig proposed that an autoimmune process may be fueling the symptoms in a subset of patients.
