Unmasking the ties of snake bite poisoning and COVID-19

Abstract

Abstract Background Snake bite envenoming is a neglected tropical disease with variable clinical presentation, neurotoxic manifestations (respiratory paralysis), rhabdomyolysis, cardiotoxicity, autonomic hyperactivity, and/or coagulation abnormalities. There is limited data on the clinical course of the envenomation in an incidentally diagnosed COVID-19 patient. Case presentation A 17-year-old male with history of snake bite and neuroparalysis developed shortness of breath. He was treated with lyophilized polyvalent anti-snake venom (ASV) on admission in the emergency department and mechanical ventilation. Subsequently, he tested positive for COVID-19 infection. No immunomodulatory therapy was administered, and patient was extubated on the 5th day of ICU admission without any neurological deficit. Conclusions Coinfections of the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) virus with snake bite poisoning lead to diagnostic dilemmas and controversies in management practices. Abnormalities of coagulation need to be cautiously addressed, and cause of development of pneumonia needs to be identified. The rapid recovery of the patient in our case theoretically can be explained on the organ-protective potential of snake-derived peptides; a large case series is however needed to prove the same.
