@Dysautonomia What the study found:
✅ Out of 59 patients who qualified for #FND diagnosis by DSMV criteria, 88% had autonomic symptoms!!!
✅ 27% were positive for ganglionic acetylcholine receptor antibody (gAchR Ab) via LIPS assay.
✅ 50% had #POTS.
✅ 50% had orthostatic hypotension.

@Dysautonomia Why is this important?
✅ Our patients are often misdiagnosed with #FND, and this study proves that.
✅ When #FND is diagnosed, treatment is psychotherapy & physical therapy, which is not a treatment for #Dysautonomia.
✅ We MUST identify and treat #Dysautonomia symptoms.

Multiple endocrine organs have receptors for ACE2.
mRNA of ACE2, the SARS-CoV2 receptor, is expressed in the thyroid cells.
ACE2 receptor is abundantly expressed by the thyroid. Elevated levels of proinflammatory cytokines could increase the expression ofACE2 on the thyroidgland.

What happens if we allow #SARS2 to become endemic? What’s going to happen to us & what’s going to happen to the virus?
If we allow it to become endemic—and some would argue that it is already endemic—this does not mean that it is going to attenuate, not whatsoever. 1/

It is not true that more transmissible versions of #SARS2 will be more benign. What we are seeing is more aggressive, more transmissible versions which are creating more severe illness. And the virus is still adapting to our physiology. It’s doing it at a fantastic rate 2/
What we’re going to see is that it will continue to work against our immune systems, meaning become more immune evasive. It’s going to become more chronic as an infection. 3/
Mark Davis now. He's talking about celiac (severe gluten intolerance/sensitivity). He found that gluten-specific CD4+ T cells were directly associated with the response. (1/6) #fatigue #celiac #autoimmunity
Interestingly, they're mentioning elevated KIR+ CD8+ cells in autoimmunity. KIR is typically thought of as a marker for NKCs, & associated with their maturation (me saying this, not M Davis). Intriguing, then, that KIR+ CD8+ cells are associated w/autoimmunity... (2/6) #fatigue
