Summary
Central diabetes insipidus (DI) is a condition causing excessive urination and thirst. Early diagnosis and treatment with desmopressin are crucial for managing DI symptoms in children.
Area of Science:
- Pediatric Nephrology
- Endocrinology
Background:
- Diabetes insipidus (DI) is a clinical syndrome characterized by polyuria and polydipsia.
- Central DI, stemming from inadequate antidiuretic hormone secretion, is the most common form, necessitating differentiation from other polyuric disorders.
Observation:
- A previously healthy 4-year-old girl presented with intense polydipsia and polyuria.
- Initial behavioral treatment for presumed psychogenic polydipsia proved ineffective, leading to referral to pediatric nephrology.
Findings:
- Diagnostic tests, including water restriction and desmopressin concentration tests, confirmed central DI.
- Cranial MRI results were normal, but the etiology remains indeterminate due to insufficient follow-up time.
- The patient became asymptomatic with intranasal desmopressin treatment.
Implications:
- This case underscores the importance of a thorough diagnostic approach for polyuria/polydipsia in children.
- Prompt diagnosis and management of central DI with desmopressin can lead to favorable patient outcomes.
