ABSTRACT

INTRODUCTION: Acute kidney injury is a well-known complication of generalized tonic-clonic seizures, most commonly due to rhabdomyolysis. Elevated serum uric acid resulting in uric acid nephropathy is an overlooked cause of acute kidney injury in these patients, with only a few published case reports.

CASE REPORT: In the first case, a 23-year-old male was admitted with status epilepticus. His kidney function worsened and he developed anuria. He had a serum uric acid level of 20.7 mg/dL and required multiple sessions of hemodialysis. In the second case, a 32-year-old male was admitted with acute kidney injury after experiencing a breakthrough seizure. He had a serum uric acid level of 20.4 mg/dL and was treated with rasburicase with recovery of renal function. In the third case, a 29-year-old male was admitted with status epilepticus. His renal function deteriorated. His serum uric acid level was 19.5 mg/dL. He required hemodialysis and rasburicase.

CONCLUSION: Uric acid nephropathy is a rare complication of generalized tonic-clonic seizures, which is poorly recognized by healthcare providers. We advocate for Nephrology consultation early in a patient’s hospitalization to discuss the use of rasburicase to avoid the associated morbidity of renal replacement therapies.
