Improvement of post-COVID-19 vaccination dysautonomia with GLP-1 receptor agonist.

BACKGROUND

Vasovagal syncope (VVS) is the most common form of cardiovascular dysautonomia that has multiple etiologies. Post-vaccination dysautonomia, in the form of VVS and postural orthostatic tachycardia syndrome, has been reported in the literature after various vaccines, including COVID-19 mRNA vaccination. Treatment of post-vaccination syndromes has not been explored leaving patients with post-vaccination dysautonomia with limited therapeutic options.

METHODS

We report a 42-year-old woman who developed post-vaccination VVS after COVID-19 mRNA vaccination and improved significantly with semaglutide treatment.

RESULTS

The patient's COMPASS-31 score decreased by 44% post-treatment, Orthostatic Hypotension Questionnaire score decreased by 59%, and an average 24-hour heart rate decreased from 97 beats per minute (bpm) to 80 bpm, indicating significant reduction in the autonomic symptom burden. In addition, her post-vaccination neuropathic pain in the legs completely resolved after treatment with semaglutide.

CONCLUSION

This case report suggests that GLP-1 receptor agonists might be beneficial for treatment of recurrent VVS, other forms of dysautonomia and post-vaccination syndromes with neuropathic pain, and may be considered as candidates for randomized placebo-controlled trials in this patient population.
