Insights
Desmopressin, used for secondary enuresis, can cause severe hyponatremia and seizures. This case highlights the risks, suggesting restricted use for desmopressin in children.
Area of Science:
- Pediatric Nephrology
- Clinical Toxicology
Background:
- Secondary enuresis and bladder instability are common pediatric conditions.
- Desmopressin is frequently prescribed for enuresis, acting as an antidiuretic agent.
Observation:
- A 4-year-old boy presented with altered mental status, vomiting, and seizures.
- These symptoms coincided with hyponatremia and hypoosmolality during desmopressin treatment.
Findings:
- The patient recovered rapidly with fluid restriction and sodium chloride administration.
- This suggests desmopressin may induce severe water intoxication and electrolyte imbalance.
Implications:
- Desmopressin carries significant risks of hyponatremia and neurological side effects.
- Consider restricting desmopressin use to cases with confirmed antidiuretic hormone deficiencies.
Abstract:
A 4-year-old boy was treated with oxybutinine and desmopressine because of bladder instability associated with secondary enuresis. He was admitted with obnubilation, vomiting and experienced two seizure episodes concomitantly with hyponatremia and hypoosmolality. The child healed promptly under water restriction and intravenous administration of sodium chloride. This case report suggests that desmopressine may be responsible for severe side-effects. This drug should not be widely used and its indications should be restricted to patients with proven antidiuretic hormone secretion abnormalities.
