Abstract:
We report comparative results, over three months, of the impact of SARS-CoV2 in our patients injected with botulinum toxin for functional purposes, compared to the general population. Botulinum neurotoxin type A (BoNT/A) is known to block acetylcholine (ACh) as well as many other neuroreceptors and neuromodulators. The recent mention of a potential protective effect of nicotine in COVID 19, by blocking ACh, attracted our attention and guided the present study. Our results show a significant difference between the number of infected individuals in the general population and the number of patients injected with BoNT/A who showed signs of COVID 19.
