Chronic kidney failure following lancehead bite envenoming: a clinical report from the Amazon region

ABSTRACT

Snakebite envenoming can be a life-threatening condition, for which emergency care is essential. The Bothrops (lancehead) genus is responsible for most snakebite-related deaths and permanent loss of function in human victims in Latin America. Bothrops spp. venom is a complex mixture of different proteins that are known to cause local necrosis, coagulopathy, and acute kidney injury. However, the long-term effects of these viper envenomings have remained largely understudied. Case presentation Here, we present a case report of a 46-years old female patient from Las Claritas, Venezuela, who was envenomed by a snake from the Bothrops genus. The patient was followed for a 10-year period, during which she presented oliguric renal failure, culminating in kidney failure 60 months after the envenoming. Conclusion: In Latin America, especially in Brazil, where there is a high prevalence of Bothrops envenoming, it may be relevant to establish long-term outpatient programs. This would reduce late adverse events, such as chronic kidney disease, and optimize public financial resources by avoiding hemodialysis and consequently kidney transplantation.(AU)
