Life-threatening hyperkalemia can cause ascending paralysis. This rare presentation occurred in a patient taking trimethoprim-sulfamethoxazole, highlighting the need for caution in patients with kidney disease.

Area of Science:

  • Nephrology
  • Pharmacology
  • Neurology

Background:

  • Hyperkalemia is a critical electrolyte imbalance with potential cardiac and neuromuscular effects.
  • Trimethoprim-sulfamethoxazole is a common antibiotic, but can interfere with potassium excretion.

Observation:

  • A case of life-threatening hyperkalemia presenting as ascending paralysis is described.
  • The patient had underlying mild renal disease, a known risk factor for hyperkalemia.

Findings:

  • The hyperkalemia was associated with standard-dose trimethoprim-sulfamethoxazole therapy.
  • This presentation is believed to be the first reported instance of hyperkalemia causing ascending paralysis.

Implications:

  • Physicians should exercise caution when prescribing trimethoprim-sulfamethoxazole to patients with renal impairment.
