Acute renal failure following wasp sting in children.

The medical records of patients admitted between 1985 and 2007 with wasp stings were retrospectively analyzed. Among the 45 children, seven developed acute renal failure. Classical clinical and laboratory data pointed to hemolysis and rhabdomyolysis as the underlying pathophysiology. All patients had hyponatremia and hyperkalemia as well as metabolic acidosis. Six patients had anemia. Five patients were oliguric for 9 to 15 days. Maximum serum creatinine was 4.0 to 11.9 mg/dl. Peritoneal dialysis was performed for 3 to 15 days. One patient died due to hyperkalemia, the remaining ones recovered completely. This paper wants to remind pediatricians to watch for acute renal failure in children with wasp stings.
