Minimal change disease after multiple wasp stings

Acute renal failure is a well-known but uncommon complication of wasp stings. In rare instances, nephrotic syndrome (NS) has also been reported in association with wasp envenomation. The occurrence of minimal change disease (MCD) as a consequence of wasp stings is even less common, with only 1 case reported to date. We report a case of a 67-year-old man, with previously normal kidney function, presenting with acute renal failure with underlying NS due to biopsy-proven MCD, 1 month following numerous wasp stings. Despite treatment with corticosteroids, the patient required hemodialysis and treatment with loop diuretics and prednisone for 6 months until complete resolution. The patient remains free of NS, with normal renal function 3 years following remission.
