Apparent Mineralocorticoid Excess

Apparent mineralocorticoid excess is a rare condition where the body acts as if it has too much aldosterone (the salt-retaining hormone), even though aldosterone is low. The problem is not the aldosterone hormone itself. The problem is that cortisol, a common stress hormone, is allowed to stimulate the mineralocorticoid receptor (MR) in the kidney. Normally, an enzyme called 11β-hydroxysteroid dehydrogenase type 2 (11β-HSD2) converts active cortisol to inactive cortisone inside kidney cells. That conversion protects the MR from cortisol. In AME, this protection fails. As a result, the kidney keeps too much salt and water, loses potassium, and blood pressure rises. This often begins in childhood, may be severe, and is linked to low renin and low aldosterone levels. BioMed Central+2PubMed+2

Other names

People use several names for the same idea:

• Syndrome of apparent mineralocorticoid excess (AME)

• 11β-HSD2 deficiency (for the inherited form)

• Pseudohyperaldosteronism (especially for acquired, non-genetic cases such as licorice-induced cases)

• Cortisol-mediated mineralocorticoid excess (describes the mechanism) UpToDate+1

Think of the kidney’s MR as a “salt switch.” Aldosterone is supposed to flip that switch on and off. Cortisol can also flip the same switch, but the kidney uses the enzyme 11β-HSD2 to “mask” cortisol by turning it into cortisone. In AME, that masking step does not work well. The MR sees more “unmasked” cortisol and stays switched on. Salt and water are retained. Potassium is lost in urine. Blood pressure climbs, and blood becomes more alkaline (metabolic alkalosis). Over time, organs like the heart and kidneys can be affected. BioMed Central+1

Types

1) Genetic (inherited) AME — “classic” AME
This type happens when both copies of the HSD11B2 gene (which makes the 11β-HSD2 enzyme) have harmful variants. It is usually autosomal recessive, so children inherit one faulty copy from each parent. It often starts early in life with severe high blood pressure, low potassium, and very low renin and aldosterone. Depending on the specific variants, enzyme activity can be nearly absent (more severe) or only partly reduced (milder). BioMed Central+2Orpha+2

2) Acquired AME (also called “pseudohyperaldosteronism”)
Here the gene is normal, but the enzyme 11β-HSD2 is blocked or overwhelmed by outside factors. Common triggers include licorice (glycyrrhizin), certain medicines (for example posaconazole, sometimes itraconazole, and carbenoxolone), and rarely high cortisol states that overpower the enzyme. The lab pattern looks like AME: high blood pressure, low potassium, low renin and low aldosterone. Stopping the trigger typically improves the condition. PMC+4PMC+4PMC+4

Causes

Below are 20 causes or triggers that create the AME pattern (cortisol acting like aldosterone at the kidney). I list genetic first, then acquired:

Genetic causes (primary 11β-HSD2 problems)

1. Biallelic pathogenic variants in HSD11B2 (classic AME; autosomal recessive). The enzyme is severely reduced or absent. BioMed Central

2. Compound heterozygous HSD11B2 variants (two different harmful variants, one from each parent), giving partial to severe enzyme loss. BioMed Central

3. Missense variants with residual activity (milder, “type II” AME phenotype; later onset). BioMed Central

4. Nonsense or frameshift variants (often severe, very early presentation). BioMed Central

5. Promoter or splice-site variants of HSD11B2 reducing enzyme expression or proper processing. BioMed Central

Acquired enzyme inhibition or saturation

1. Licorice (glycyrrhizin/glycyrrhetinic acid)—in sweets, teas, herbal products; classic inhibitor of 11β-HSD2. New England Journal of Medicine+1
2. Carbenoxolone—a potent 11β-HSD inhibitor used historically; can cause an AME-like state. PMC
3. Posaconazole—an antifungal; multiple reports show hypertension, hypokalemia, low renin/aldosterone via 11β-HSD2 or related steroid enzyme inhibition. PMC+1
4. Itraconazole—another azole antifungal; can inhibit 11β-HSD2 and produce a similar picture in some patients. ScienceDirect+1
5. Grapefruit juice flavonoids—in vivo studies show they can reduce 11β-HSD2 activity and tilt cortisol/cortisone balance. Effect is usually mild but relevant in susceptible people. PMC+1
6. Very high cortisol states (for example, some forms of Cushing syndrome or ectopic ACTH) can saturate 11β-HSD2, letting cortisol activate the MR. UpToDate
7. Topical/herbal products containing licorice extract—less obvious source that still inhibits 11β-HSD2 in some users. Frontiers
8. Certain complementary or traditional medicines with undeclared glycyrrhizin or similar compounds. BioMed Central
9. Chronic very high-dose glucocorticoids with mineralocorticoid activity (rare mechanism; pharmacologic saturation of MR protection). UpToDate
10. Specific food concentrates or beverages high in glycyrrhizin (some teas, candies, syrups). New England Journal of Medicine
11. Carbenoxolone-like supplements or research compounds used outside clinical care. PMC
12. Certain drug interactions that raise posaconazole/itraconazole levels, increasing 11β-HSD2 inhibition risk. eScholarship
13. Renal epithelial stress plus inhibitors (for example, dehydration + grapefruit juice + licorice) tipping the balance toward AME physiology. PMC
14. Rare environmental inhibitors reported in research (e.g., gossypol, phthalates) that can inhibit 11β-HSD2 activity in models; clinical impact varies. ResearchGate
15. Familial clustering in certain populations because of founder HSD11B2 variants (reported in case series). Frontiers

Common symptoms

1. High blood pressure—often strong, can start in childhood or young adulthood. May cause headaches or nosebleeds. BioMed Central

2. Low potassium symptoms—muscle weakness, cramps, fatigue, and in severe cases temporary paralysis. BioMed Central

3. Excess thirst (polydipsia) and frequent urination (polyuria)—from kidney salt handling changes and low potassium. BioMed Central

4. Metabolic alkalosis effects—tingling, lightheadedness, or muscle twitching. BioMed Central

5. Poor growth or failure to thrive in children—due to chronic high blood pressure and electrolyte losses. Orpha

6. Irritability or tiredness—nonspecific but common when potassium is low and blood pressure is high. BioMed Central

7. Dizziness—especially when standing, related to pressure changes or electrolyte imbalance. BioMed Central

8. Headaches—from high blood pressure. BioMed Central

9. Blurred vision or visual spots—when blood pressure is very high and affects the eyes. NCBI

10. Constipation—a feature of low potassium. BioMed Central

11. Heart palpitations—low potassium can disturb heart rhythm. BioMed Central

12. Muscle aches—linked to potassium loss. BioMed Central

13. Swelling is usually mild or absent—salt retention can occur, but edema is not always obvious in AME. BioMed Central

14. Signs of long-standing high pressure—like left ventricular thickening over time. NCBI

15. Symptoms after licorice or certain medicines—blood pressure and potassium changes that start after a new food, drink, or drug. BioMed Central

Diagnostic tests

I group the tests by category. Doctors do not need all tests for every person. They choose based on your story and exam.

A) Physical examination

1. Blood pressure check (sitting and repeated)
   This is the most important bedside test. AME usually shows high readings that are persistent and sometimes severe, especially in young people. In children, doctors compare numbers to age-based percentiles. PMC

2. Growth and development assessment
   In children, high blood pressure and salt loss can slow growth. Tracking height and weight over time helps catch this. Orpha

3. Volume status signs
   Doctors look for signs of too much salt and water (like high blood pressure and sometimes mild swelling), but obvious swelling may be absent. BioMed Central

4. Eye (fundus) check
   Severe or long-term high blood pressure can affect the back of the eye (retina). A quick light check (fundoscopy) looks for damage. NCBI

5. Family and nutrition review
   Questions about licorice sweets, herbal teas, and antifungal medicines are key. Stopping a trigger can fix the problem in acquired cases. PMC+1

B) “Manual” bedside tests

6. Orthostatic vitals (lying to standing)
   Simple bedside measure to see how blood pressure behaves with posture; it can support overall blood pressure assessment in a safe, quick way. (Adjunct, not diagnostic by itself.) PMC

7. Dietary recall or “licorice test” by history
   There is no true “manual licorice test,” so history is crucial. A careful food/medicine diary often reveals hidden sources (candies, teas, syrups, herbal mixes, or creams). New England Journal of Medicine

8. Home blood pressure log
   Multiple readings at home confirm persistent hypertension and help avoid “white-coat” effects. This supports diagnosis and treatment choices. PMC

C) Laboratory and pathological tests

9. Serum electrolytes
   Low potassium and metabolic alkalosis are common clues. Sodium may be high-normal. These findings fit a pattern of mineralocorticoid effect. BioMed Central

10. Plasma renin activity (or renin concentration)
    Renin is usually suppressed (low) because the body senses salt and water expansion. This is a hallmark of AME and other mineralocorticoid states. PMC

11. Plasma aldosterone
    Aldosterone is usually low in AME (hence “apparent” mineralocorticoid excess). The body does not need aldosterone because cortisol is wrongly turning on the MR. BioMed Central

12. 24-hour urine steroid profile
    This is a key confirmatory test. Doctors measure the ratio of cortisol metabolites (THF + allo-THF) to cortisone metabolite (THE). In AME, the THF+allo-THF:THE ratio is high. This shows poor conversion of cortisol to cortisone. Yonsei Medical Journal

13. Urinary free cortisol to cortisone ratio
    Another way to show that 11β-HSD2 is not working well or is inhibited. The cortisol:cortisone ratio is increased. BioMed Central

14. HSD11B2 genetic testing
    For suspected inherited AME, sequencing the HSD11B2 gene confirms the diagnosis and helps with family counseling. Orpha

15. Medication and toxin screen (targeted)
    When acquired AME is possible, clinicians look for licorice glycyrrhizin, posaconazole, itraconazole, carbenoxolone, and other inhibitors. Clinical history is key; drug levels may be checked for azoles. PMC+1

16. Cortisol and ACTH tests
    If cortisol-overproduction is suspected (for example, Cushing syndrome), doctors will test morning cortisol, ACTH, and sometimes do dexamethasone suppression tests, because very high cortisol can overwhelm 11β-HSD2. UpToDate

17. Basic kidney function tests (creatinine, eGFR, urinalysis)
    These check kidney health, look for protein or blood in urine, and assess any damage from long-term high blood pressure or potassium loss. BioMed Central

D) Electrodiagnostic tests

18. Electrocardiogram (ECG)
    Low potassium can show U waves, ST-segment changes, or rhythm problems on ECG. This is a quick and important safety test in hypokalemia. BioMed Central

19. Echocardiogram
    High blood pressure over time can thicken the left ventricle. An ultrasound of the heart checks for left ventricular hypertrophy and function. NCBI

E) Imaging tests

20. Renal ultrasound
    An ultrasound can look for nephrocalcinosis or structural kidney issues that may occur with long-standing salt and potassium losses. It also helps exclude other causes of hypertension. (Other imaging—CT/MRI—may be used when ruling out different diseases, such as adrenal tumors in hypercortisol states.) PMC

Non-pharmacological treatments

1) Strict low-sodium diet.
Description: Limit added salt and ultra-processed foods; target <1.5–2 g sodium/day if your clinician agrees. Purpose: Lower blood pressure and reduce potassium loss.

15) Regular eye and heart checks.
Description: Periodic retina exam and echocardiography. Purpose: Track organ effects of long-term hypertension. Mechanism: Early detection of complications like LVH, retinopathy. PubMed

16) School/work accommodation plans (pediatrics).
Description: Access to fluids, bathroom breaks, BP checks. Purpose: Safety during treatment. Mechanism: Reduces risk from hypokalemia symptoms. BioMed Central

17) Sick-day rules.
Description: Clear steps during vomiting/diarrhea (call team, monitor K⁺/BP). Purpose: Prevent dangerous potassium drops. Mechanism: Early testing and dose adjustments. BioMed Central

18) Avoid “mineralocorticoid-like” cosmetics/herbals.
Description: Some cosmetics contain licorice extract—usually small amounts but best avoided in AME. Purpose: Minimize cumulative inhibition. Mechanism: Prevents tiny but chronic 11β-HSD2 blockade. BioMed Central

19) Family screening when appropriate.
Description: Test siblings if index case confirmed. Purpose: Early diagnosis and treatment. Mechanism: Finds presymptomatic cases before damage occurs. AHA Journals

20) Multidisciplinary follow-up.
Description: Nephrology, endocrinology, genetics, dietetics. Purpose: Coordinated care. Mechanism: Aligns diet, meds, and monitoring for best outcomes. BioMed Central

Drug treatments

Dietary molecular supplements

There is no supplement that cures AME. The items below can support blood pressure or electrolyte goals when your clinical team agrees. Always review for licorice or hidden sodium before taking anything.

1) Potassium citrate or chloride (medical supplement).
Dose: Individualized. Function/mechanism: Replaces K⁺ to counter renal wasting; citrate form may help urine chemistry if stones/hypercalciuria. Revista Nefrología

2) Magnesium (if low).
Dose: Commonly 200–400 mg elemental/day, adjusted. Function/mechanism: Aids potassium retention and cardiac stability. BioMed Central

3) Omega-3 fatty acids (EPA/DHA).
Dose: ~1–2 g/day (as advised). Function/mechanism: Small BP-lowering effect via vascular and anti-inflammatory pathways; adjunct only. BioMed Central

4) Coenzyme Q10 (adjunct).
Dose: 100–200 mg/day. Function/mechanism: Modest BP signals in some studies; not AME-specific. BioMed Central

5) Vitamin D (if deficient).
Dose: Correct deficiency per guidelines. Function/mechanism: Overall cardiovascular and bone health; not AME-specific. BioMed Central

6) Calcium (diet-first; supplement if needed).
Dose: Per age/sex needs. Function/mechanism: Bone health; thiazides reduce urine calcium—coordinate with your team. Revista Nefrología

7) Folate-rich diet (or folic acid if indicated).
Dose: As advised. Function/mechanism: Vascular health; adjunct only. BioMed Central

8) Beetroot (dietary nitrate).
Dose: Food-based. Function/mechanism: Short-term BP effects via nitric oxide pathway; not a substitute for AME meds. BioMed Central

Immunity-booster/regenerative/stem-cell drugs

There are no approved immune-booster, regenerative, or stem-cell drugs for AME. Using such products outside a research study is not recommended. The only disease-modifying intervention beyond medicines is kidney transplantation in severe, refractory cases; this supplies a kidney with normal 11β-HSD2 and can normalize physiology. Always discuss experimental ideas with an academic center. Cloudfront

---

Surgeries

1) Kidney transplantation (the one surgery with disease-level impact).
Procedure: Standard renal transplant. Why done: For end-stage renal disease from long-standing, uncontrolled AME or rare severe cases; it corrects the enzyme defect at the kidney level and can “cure” the renal physiology. Cloudfront

The following are generally not indicated for AME but may appear in broader hypertension care and are not standard in children with AME:
2) Renal sympathetic denervation (experimental/resistant HTN). 3) Bariatric surgery (only for obesity-driven hypertension, not AME). 4) Adrenal surgery (for primary aldosteronism—not AME). 5) Neurosurgical/endocrine procedures for Cushing (only if cortisol excess is the cause of an AME-like state). These are listed to clarify distinctions; they are not AME treatments. Wiley Online Library

---

Preventions

1. Genetic counseling in affected families. 2) Screen siblings when a case is confirmed. 3) Avoid licorice in all forms. 4) Read labels on teas, candies, herbal mixes. 5) Maintain low-sodium eating. 6) Keep potassium intake adequate as advised. 7) Adherence to ENaC/MR blockers. 8) Regular BP and lab checks. 9) Early pediatric evaluation for growth/BP changes. 10) Coordinate care across life stages (school, pregnancy, transition to adult care). BioMed Central+2AHA Journals+2

When to see a doctor

Seek urgent care for severe headache, chest pain, shortness of breath, fainting, very high BP readings, muscle paralysis, or palpitations, as these may reflect dangerous hypertension or very low potassium. Contact your care team promptly for new weakness, cramps, vision changes, swelling, medication side-effects, or if you discover you’ve been consuming licorice. Children with early high BP, poor growth, or low potassium need specialist evaluation quickly. BioMed Central

---

What to eat and what to avoid

Eat more: 1) Fresh fruits/vegetables (potassium-rich, if allowed). 2) Legumes and unsalted nuts. 3) Plain yogurt/milk (check sodium). 4) Whole grains. 5) Herbs, spices, lemon, vinegar for flavor. Avoid/limit: 6) Licorice in any product. 7) High-sodium foods (soups, instant noodles, pickles, chips, cured meats). 8) Salty sauces (soy, fish sauce)—use low-sodium versions sparingly. 9) “Detox” or “adrenal” teas/supplements that may hide licorice. 10) Energy drinks/sweets with licorice flavorings. BioMed Central+1

FAQs

1) Is AME the same as high aldosterone?
No. In AME, aldosterone is low, but cortisol wrongly turns on the same kidney receptor. BioMed Central

2) How is AME diagnosed?
By history/physical, labs (low renin/aldosterone, low K⁺), urine steroid profile, and HSD11B2 genetic testing. BioMed Central+1

3) What foods must I avoid?
Anything with licorice (glycyrrhizic acid) and high-sodium products. Check labels carefully. BioMed Central

4) Which medicines work best?
Amiloride or triamterene (ENaC blockers) and/or MR antagonists (spironolactone, eplerenone). Choice depends on age, labs, side-effects. Revista Nefrología+1

5) Do I need potassium pills?
Often yes, especially early on; your team will tailor the dose to your labs. BioMed Central

6) Does dexamethasone help?
Sometimes, by lowering cortisol production, but response is variable and side-effects limit use; specialists decide case-by-case. Revista Nefrología

7) Can AME damage organs?
Yes—long-term uncontrolled hypertension can affect the heart, eyes, kidneys, and brain, so early treatment is vital. PubMed

8) Will a low-salt diet really matter?
Yes. Lower sodium reduces the kidney’s sodium reabsorption drive and helps control BP and potassium loss. BioMed Central

9) Is AME always genetic?
Usually, but licorice and some drugs can cause an AME-like state even without a gene mutation. BioMed Central

10) Can children live normal lives?
With early diagnosis, proper diet, and the right medicines, most children can grow and thrive well. ScienceDirect

11) Will I always need medicines?
Many people need long-term therapy, but doses may change over time with careful follow-up. BioMed Central

12) Is kidney transplant a cure?
For severe genetic AME with kidney failure, transplant can correct the enzyme problem in the new kidney and normalize physiology. Cloudfront

13) Are there approved stem-cell or gene therapies?
No approved options yet; discuss clinical trials only at academic centers. BioMed Central

14) What if I accidentally ate licorice?
Tell your clinician, check BP and potassium, and stop licorice immediately; adjust meds if needed. BioMed Central

15) Where can I read more?
See high-quality overviews and reviews from BMC Translational Medicine, GARD/NIH, Orphanet, and recent case reports linked in the citations. BioMed Central+2Genetic Diseases Center+2
