“There is quite convincing documentation that supports that the MEtabolic energy turnover is disturbed by #ME. By metabolic energy MEtabolism we mean the biochemical processes in the body, that transform, distribute and utilize energy sources in the food👇🏻 forskersonen.no/cellebiologi-k…
“Oxygen is the most important single factor for the cells' production of the important energy molecule ATP. The oxygen consumption of the muscle cells increases dramatically during physical work, but it has a limit. As the oxygen supply becomes insufficient, 👇🏻 #PwME #MEcfs
the production of lactic acid (lactate) increases, and then the working capacity of the muscle will rapidly decrease.” #MEcfs #PwME #ImmunoMEtabolism #ATP #KrebsCycle

Working through an interesting cardiopulmonary exercise test!
For any physiology fans or new pulmonary and cardiology fellows out there

Lets make sense of all this information: ImageImageImage
Starting off with the HPI:
70 yo M PMH of HF(45% EF), LAD, PDA coronary disease requiring PCI and coronary stenting. Now reports dyspnea on exertion that has been progressive for the past 8 years. First noted when golfing but now even on mild-moderate exertion.
These were the results obtained from our CPET. The patient’s maximum oxygen consumption (VO2 max) was only 73% of predicted (LOW) ImageImage

1/ The problem with Myalgic Encephalomyeltis/Chronic Fatigue Syndrome #MECFS is that it seems so ridiculous that exercise could actually make patients worse

How can exercise be so bad for #pwME but so good for almost every other serious illness?

THREAD
2/ New study by @4WorkWell @sunsopeningband et al shows that #MECFS patients have metabolic defects that cannot be explained by exercise phobias, deconditioning or 'illness beliefs'

#pwME have reduced oxygen consumption during exercise tests

3/ #pwME have an impaired ability to increase their oxygen consumption during exercise

This is entirely different to every other disease we know including cardiovascular disease, lung disease, end-stage renal disease, hypertension & cystic fibrosis

18 myths & misconceptions of Post-Exertional Malaise #PEM in Myalgic Encephalomyelitis/Chronic Fatigue Syndrome #MECFS

#PEM (aka PENE, "flare" or “crash”) is seriously debilitating symptom caused by exercise

#SickNotWeak #SickNotTired #pwME #chronicillness #medtwitter #MedEd
1. #PEM is just tiredness

No

#pwME experience <pathological> fatigue after #exercise which can be long-lasting and includes debilitating fatigue, flu-like symptoms, cognitive impairment, #sleep disturbance

2. #PEM is not a real

No

“there exists no medical condition.. where exertion.. causes #immune/ inflammatory-related symptoms like sore throat, tender lymph nodes, or flu-like feelings, yet 60%.. of.. [#pwME].. reported these symptoms”
