[Bee venom: an unusual cause of acute kidney injury].

Introduction: Bee sting venom is generally well tolerated. However, some rare cases of massive stings can lead to anaphylactic shock and even renal failure. This observation is the illustration of a case of acute kidney injury secondary to bee stings in a 64-year-old black african subject.

Case Presentation: A 64-year-old man without a known medical history was referred to the emergency department of the Fousseyni Daou hospital in Kayes (Mali) for disturbed consciousness 4 hours after massive stings from a bee swarm. Renal failure with serum creatinine level at 752,2 µmol/L was documented on day 3 in a context of total anuria. The patient was transferred to a nephrology unit and biology confirmed renal failure associated with intravascular haemolysis and rhabdomyolysis. The kidneys were of normal size and well differentiated. The diagnosis of severe acute kidney injury due to massive envenomation induced by bee venom was evoked. The evolution was favourable, with normalization of renal function at D26 after 5 sessions of haemodialysis in parallel with transfusions of packed red blood cells.

Conclusion: A massive bee attack should be considered a medical emergency because of the organic damage it can inflict. The renal prognosis depends on the number of stings, and especially on the delay and the quality of the treatment. Early initiation of dialysis treatment reduces mortality.
