[Acute renal failure due to cyclical vomiting syndrome].

HISTORY AND ADMISSION FINDINGS: A 29-year-old man was admitted because of recurrent episodes of vomiting.

DIAGNOSIS: The admission diagnosis was acute anuric renal failure. Ultrasound was unremarkable and there had been no history of renal disease. The serum creatinine concentration was 5.48 mg/dl. The urinary findings were normal. The final diagnosis was therefore of prerenal failure with dehydration. Cyclical vomiting syndrome was the working diagnosis, having excluded other possible causes.

TREATMENT: Normal renal functions were re-established with rehydration treatment.

CONCLUSION

Cyclical vomiting syndrome is an illness characterized by recurrent bouts of vomiting, often associated with migraine but of uncertain etiology. Therapeutic options include anti-emetics and anti-migraine medication.
