Insights
Hyponatremic-hypertensive syndrome (HHS) in children, rare and linked to renal artery issues, was successfully treated. Surgical removal of Wilms tumor resolved HHS symptoms, enabling further cancer treatment.
Area of Science:
- Pediatric Nephrology
- Pediatric Oncology
- Hypertension Research
Background:
- Hyponatremic-hypertensive syndrome (HHS) is a rare condition in children, often linked to renal artery occlusions.
- It presents with low sodium levels and high blood pressure, requiring careful management.
Observation:
- Two pediatric cases of HHS were observed with severe hypokalemia, polyuria, and polydipsia.
- These symptoms were associated with the presence of Wilms tumor.
Findings:
- Treatment with an angiotensin-converting enzyme inhibitor was initiated before surgical intervention.
- Complete resolution of HHS signs and symptoms occurred only after the Wilms tumor was surgically resected.
- Tumor resection facilitated the commencement of necessary chemotherapy.
Implications:
- This case series highlights the critical link between Wilms tumor and HHS in pediatric patients.
- Early diagnosis and surgical management of the tumor are crucial for resolving HHS.
- Successful treatment of HHS enables effective oncological therapy, improving patient outcomes.
Abstract:
The combination of hyponatremia and renovascular hypertension is known as hyponatremic-hypertensive syndrome (HHS) and so rarely described in children but associated with various kinds of occlusions of the renal artery. We describe two children who presented HHS with severe hypokalemia, polyuria, and polydipsia associated with Wilms tumor, which required treatment with an angiotensin-converting enzyme inhibitor before nephrectomy. All HHS signs and symptoms resolved only following surgical resection of the tumor, allowing chemotherapy to be given.
