Transient Coagulopathy Due to Wasp Sting: A Case Report.

BACKGROUND: Insect venom anaphylaxis is a potentially life-threatening disorder. Transient coagulopathy in insect venom anaphylaxis is a rare phenomenon. CASE REPORT: A 41-year-old man presented to the Emergency Department (ED) with hypotension after a run in a park. History and examination revealed signs of anaphylactic shock. A deranged coagulation profile with a normal platelet count led to the diagnosis of wasp sting anaphylaxis. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Transient deranged coagulation profile with a normal platelet count may arise from insect venom anaphylaxis. This specific finding may aid the emergency physician in making a diagnosis of anaphylactic shock in an otherwise healthy patient presenting with shock with no apparent cause.
