The following is a summary of “Challenges in Diagnosing and Managing the Spectrum of Primary Aldosteronism,” published in the July 2024 issue of Endocrinology by Yang, et al.


Primary aldosteronism is the most common endocrine cause of hypertension, characterized by excessive aldosterone production from one or both adrenal glands. This condition carries a heightened risk of cardiovascular, renal, and metabolic complications, which can be managed effectively with targeted medical therapy or surgery. However, diagnosing primary aldosteronism presents challenges such as medication interference, intra-individual variability, and concurrent autonomous cortisol secretion. Ensuring accurate diagnosis and timely treatment is crucial for optimizing patient outcomes. For a study, researchers sought to illustrate diagnostic challenges and treatment strategies through case studies from our endocrine hypertension clinic.

They reviewed cases from the endocrine hypertension clinic to highlight diagnostic complexities encountered in primary aldosteronism. The diagnosis was established based on screening tests indicating elevated aldosterone to renin ratio, followed by confirmatory tests including saline infusion, captopril challenge, fludrocortisone suppression, or oral salt load tests. Subtyping involved adrenal imaging and adrenal vein sampling to distinguish unilateral from bilateral disease.

Case studies demonstrated various diagnostic hurdles, including medication interference, variations in biochemical profiles over time, and the coexistence of autonomous cortisol secretion. Successful diagnostic pathways were achieved through comprehensive screening and confirmatory testing protocols. Following diagnosis, meticulous follow-up was essential to monitor treatment efficacy, manage adverse effects, and promptly address potential recurrence.

Due to its complex nature and potential pitfalls, primary aldosteronism necessitates a rigorous diagnostic approach. Effective management requires close collaboration between clinicians and ongoing patient monitoring to achieve treatment goals and optimize long-term outcomes. Case studies underscore the importance of tailored diagnostic strategies and vigilant management to mitigate risks associated with primary aldosteronism.
