Case report highlights severe hyponatremia and hyperkalemia in infancy, suggesting possible secondary pseudohypoaldosteronism due to a urinary tract infection.
Key Points
Secondary pseudohypoaldosteronism is critically linked to severe electrolyte disturbances in an infant.
The male infant presented with severe hyponatremia of 119 mmol/L and hyperkalemia of 6.6 mmol/L.
Investigative measures led to the diagnosis of Escherichia coli urinary tract infection as the root cause.
Differentiating secondary pseudohypoaldosteronism from congenital adrenal hyperplasia is essential in pediatric cases.
