Non-fatal acute renal failure due to wasp stings in children

We report two children who developed acute renal failure after multiple wasp stings. Each case involved intravascular hemolysis which caused acute renal failure, volume overload, hypertension, anemia, hyponatremia, hyperkalemia, and metabolic acidosis. Peritoneal dialysis was required for short periods. The children recovered completely with blood urea nitrogen and creatinine returning to normal within 3 months. One child had a renal biopsy which showed mild tubulointerstitial nephritis. Although there is no specific treatment or antivenom, dialysis and supportive care have proved to be successful.
