Summary

This study was a single-center randomized controlled trial which lasted 14 days and consisted of two stages (run-in period (stage I) and intervention period (stage II) each contain 7 days without potassium supplement. If participants meet the enrollment criteria at the end of stage I, they were assigned to the low sodium group (50mmol/d) or normal sodium group (100mmol/d), and then continued to finish stage II. The primary outcome was the change in serum potassium after exposure to normal sodium / low sodium diet and the secondary outcome was the assessment of BP change following a normal sodium / low sodium diet. Patients were given nifedipine controlled-release tablets 30 mg/d to lower blood pressure and were not provided any potassium supplements during the two stages. If the subject has an increase in BP (\>180/110 mmHg), the dose of nifedipine controlled-release tablets will be increased to 60 mg/d. Patients will be withdrawn from the study if they cannot tolerate the diet or their serum potassium were below 2.8 mmol/L.

Conditions

  • Primary Aldosteronism Due to Adrenal Hyperplasia (Bilateral)

Interventions

DIETARY_SUPPLEMENT

Sodium

50 IHA patients were randomized into two groups with low sodium (50mmol/d) and normal sodium (100mmol/d) without potassium supplement. A 14 days dietary intervention was performed respectively to compare the changes in blood pressure (BP) and serum potassium in two groups.
