Summary

Primary aldosteronism, an adrenal gland disorder, causes hypertension. Early diagnosis of subtypes like aldosterone producing adenoma is crucial for effective treatment.

Area of Science:

  • Endocrinology
  • Hypertension Research
  • Adrenal Gland Disorders

Background:

  • Primary aldosteronism (PA) involves autonomous aldosterone overproduction from the adrenal zona glomerulosa.
  • PA is often underestimated as a cause of hypertension.
  • Key subtypes include aldosterone producing adenoma (APA) and idiopathic hyperaldosteronism (IHA).

Purpose of the Study:

  • To analyze the clinical, biological, radiological, and evolutive features of primary aldosteronism cases.
  • To emphasize the importance of precise etiologic diagnosis for optimal treatment selection.

Main Methods:

  • Retrospective case series analysis of 18 patients diagnosed with primary aldosteronism.
  • Inclusion criteria: hypertension and hypokalemia (K < 3.5 mmol/l).

  • Evaluation included clinical presentation, laboratory results, imaging, and follow-up.

    • Main Results:

    • 18 PA cases (14 female, 4 male; mean age 42 ± 13.5 years) were analyzed.
    • All patients presented with hypertension and hypokalemia.
    • Diagnoses included APA (11 cases), adrenal carcinoma (1 case), and IHA (3 cases); 3 cases remained undiagnosed.
    • APA was the most frequent subtype identified.

    Conclusions:

    • Accurate etiologic diagnosis in primary aldosteronism is essential for tailoring appropriate therapeutic strategies.
    • Understanding the diverse clinical and biological profiles of PA subtypes aids in patient management.
    • Further investigation is needed for undiagnosed PA cases to determine specific etiologies.
