Our findings suggest that dysbiosis already exists in newly diagnosed and untreated MG patients, implying that dysbiosis within the gut microbiota may be an initiating factor contributing to MG pathogenesis. Furthermore, F. prausnitzii may hold promise as a probiotic for treating MG.

- |||||||||| Retrospective data, Review, Journal: Altered Cardiac Autonomic Regulation in Individuals with Myasthenia Gravis-A Systematic Review and Meta-Analysis. (Pubmed Central) - Sep 27, 2023
MG patients vs. HCs had higher systolic blood pressure (g = 0.39; I = 56.1), sympathovagal balance at rest/during tilt (LF/HF-RRI, g = 0.44; I = 0; LF/HF-RRI, g = 0.86; I = 0; LF/HF, g = 0.40; I = 0). As a group, MG patients have altered cardiac autonomic function, including decreased parasympathetic function, lower baroreflex sensitivity, and higher sympathovagal balance at rest and during orthostatic challenges.

A signal for potential association with ICI triad subset was seen with genitourinary cancers that will require further investigation. A strong trend for increased early mortality in the ICI triad subset closely following ICI initiation was observed in comparison to patients with myositis alone and ICI-treated veterans without myositis.
