Diagnosis of primary aldosteronism results in either the surgical cure of hypertension or targeted pharmacotherapy. The two major subtypes of primary aldosteronism are unilateral aldosterone-producing
adenoma
(APA) and bilateral idiopathic hyperaldosteronism (IHA). Patients with APA usually are treated with unilateral adrenalectomy and patients with IHA are treated medically. The majority of patients with primary aldosteronism have the IHA subtype and require pharmacotherapy. Spironolactone has been the drug of choice to treat primary aldosteronism. However, it is not selective for the aldosterone receptor, and side effects include gynecomastia, erectile dysfunction and menstrual irregularity.
Eplerenone
is a new competitive and selective aldosterone receptor antagonist recently approved by the United States Food and Drug Administration for the treatment of hypertension. It lacks the side effects associated with spironolactone and will be the superior drug if it is shown to be as effective as spironolactone for the treatment of mineralocorticoid-dependent hypertension.

Primary hyperaldosteronism (PHA) is characterized by an increased Aldosterone synthesis which is independent of the Renin-Angiotensin-Aldosterone-System (RAAS). The prevalence of PHA in patients who present in specialized hypertension centers is approx. 10 %. Besides patients with the classical symptoms known as "Conn-Trias" (hypertension, hypokalemia, metabolic alkalosis), the more frequent normokalemic patients with PHA also show a worse outcome compared to patients with essential hypertension. Identifying these patients is an important task in the evaluation of hypertension since targeted treatment options are available. Screening for PHA using the Aldosterone-Renin-Ratio (ARR) should be performed in patients with hypokalemic, severe or resistant hypertension. In addition, young patients with early onset of severe hypertension and/or positive family history should be screened. A positive screening result should be followed by a confirmatory test. The saline infusion test is the preferred clinical test for confirming a suspected PHA since it is accessible and time efficient. Other confirmatory tests are not used on a regular basis. After any confirmatory test, CT- or MRI-imaging and adrenal vein sampling (AVS) is used in order to differentiate between a unilateral
adenoma
, a bilateral hyperplasia or another cause of PHA. CT or MRI usually cannot discriminate smaller tumors form hyperplasia. Therefore AVS is used to detect lateralization of autonomous aldosterone production. Lateralization of aldosterone production indicates a unilateral
adenoma
. In these cases, laparoscopic adrenalectomy is the therapeutic option of choice with a hypertension cure rate of up to 60 %. If no lateralization is detectable, bilateral hyperplasia as the underlying cause of PHA is likely. Pharmacological inhibition of the mineralocorticoid receptor is the preferred treatment option in these cases. If Spironolactone is not well tolerated,
Eplerenone
and potassium-sparing diuretics should be prescribed. Often, however, in order to fully control hypertension, additional antihypertensive therapy is necessary.

Primary aldosteronism (PA) is the most common cause of secondary hypertension. In this review, we discuss the diagnosis and management of PA during pregnancy based on the literature. As aldosterone and renin are physiologically increased during pregnancy and confirmation tests are not recommended, the diagnosis of PA during pregnancy relies on a repeatedly suppressed plasma renin level. Mineralocorticoid receptor antagonists (MRAs) are the most effective drugs to treat hypertension and hypokalemia in patients with PA. However, spironolactone (FDA pregnancy category C) might lead to undervirilization of male infants due to the anti-androgenic effects. Although data in the literature are very limited, treatment with spironolactone is not recommended.
Eplerenone
(FDA pregnancy category B) is a selective MRA without anti-androgenic potential. If MRA treatment is required in pregnancy, eplerenone appears to be a safe and effective alternative, although symptomatic treatment with approved antihypertensive drugs and supplementation with potassium is the first choice. In case of aldosterone-producing
adenoma
, laparoscopic adrenalectomy is a therapeutic option in the second trimester of pregnancy.
