Abstract:
An increased plasma aldosterone concentration, with suppressed plasma renin activity (PRA), is an abnormal finding in primary hyperaldosteronism. A suppressed PRA is caused by aldosterone- dependent sodium retention and extracellular volume expansion. A case of primary hyperaldosteronism, due to adenoma, with increased PRA, was observed. An adrenalectomy and intraoperative renal biopsy was performed. In our patient, histologically proven renal arteriosclerosis was the probable cause of the escape of the PRA from the suppression by an aldosterone-producing adenoma. Normal blood pressure was not attained after the adrenalectomy. However, the blood pressure was then controlled by small doses of antihypertensive drug before resection of the tumor. In this case, the patient was treated with spironolactone, but the blood pressure was not correctly controlled. After the adrenalectomy, the blood pressure was well controlled with smaller dose of calcium channel blockers. So, an early adrenalectomy may be beneficial as soon as the diagnosis of an aldosterone-producing adenoma is confirmed, even in patients with hypertensive nephrosclerosis.
