CFIDS Assoc. Post-Exertion Malaise Webinar, Thursday, July 19

July 19 Update: On Thursday, July 19 at 2 pm EST, the CFIDS Association of America hosted a webinar on the information that ME/CFS patients ask for most – post exertion relapse. It is now over.

The webinar – “Top 10 Things You Need to Know about Post-Exertion Relapse” – will feature the Pacific Fatigue Lab’s exercise physiologists Staci Stevens, Chris Snell, and Mark Van Ness.

This trio of fatigue analysts has worked for years, helped by CFIDS Association funding, to develop: 1) measures of post-exertion malaise (PEM), as a diagnostic test for chronic fatigue syndrome, and 2) measures of multiple body system functions as part of comprehensive disability evaluations.

Your questions invited. You can help shape their presentation by submitting any questions you have when you register.

    We have found that PEM is not present in some people with ME. Examples include people tested for ME at the cellular level eg with the following markers:
    Low NKC bright cell function and number
    elevated TNFalpha and IFN gamma
    Orthostatic intolerance
    Chemical hypersensitivity
    Post exertional fatigue (but not malaise)
    Chronic diarrhea
    periodic swollen lymph nodes
    Urinary frequency
    and others.

    Those with MCS show post chemical exposure malaise

    This tells us that the malaise is possibly due to a rise in ROS, whether it is due to exertion or toxic exposure or even psychological stress. The exertion is then probably physiologically stressful as is chemical exposure and psychological stress. It should be called post-stressor malaise.

    It would be good to submit a question about whether they have found subsets regarding PEM. If so, what does it mean diagnostically.
