Summary

Thyrotoxic hypokalemic periodic paralysis (THPP) is rare in Black patients. This study highlights two cases, emphasizing the need to test for hyperthyroidism in acute paralysis with hypokalemia, regardless of race.

Area of Science:

  • Endocrinology
  • Neurology

Background:

  • Thyrotoxic hypokalemic periodic paralysis (THPP) is predominantly observed in Asian populations.
  • Cases in Caucasian and Black individuals are infrequent, with limited documented instances in Black patients.

Observation:

  • This report details two cases of THPP in Black patients presenting with varying degrees of hypokalemia and paralysis.
  • One patient experienced severe flaccid tetraplegia with respiratory and cardiac compromise, while the other had mild hypokalemia.
  • Hyperthyroidism was confirmed via biological tests in one case and was previously diagnosed but undertreated in the other.

Findings:

  • Prompt potassic treatment led to complete paralysis relief in the severe case.
  • Spontaneous recovery of paralysis occurred in the second patient.

  • Both cases underscore the association between hyperthyroidism and periodic paralysis.

    • Implications:

    • The study emphasizes the necessity of screening for hyperthyroidism in all patients presenting with acute paralysis and hypokalemia.
    • Early diagnosis and treatment of hyperthyroidism are crucial for managing THPP, irrespective of patient ethnicity.
    • This research expands the understanding of THPP presentation and management in underrepresented populations.
