Autoimmune Polyendocrinopathy-Candidiasis-Ectodermal Dystrophy (APECED)

Autoimmune Polyendocrinopathy-Candidiasis-Ectodermal Dystrophy (APECED) is a rare inherited immune-system disease that usually begins in childhood. It happens when a single gene called AIRE does not work properly. The AIRE gene normally teaches young immune cells in the thymus not to attack the body’s own organs (this is called “central tolerance”). When AIRE is broken, self-reactive immune cells escape that “school” and later attack many organs. Classic problems include long-lasting yeast infections of the mouth and skin (chronic mucocutaneous candidiasis), low calcium from an underactive parathyroid (hypoparathyroidism), and low cortisol from damaged adrenal glands (primary adrenal insufficiency/Addison’s disease). Many people also have hair, skin, nail, tooth, and eye surface changes (ectodermal features). APECED is autosomal recessive, which means a child is affected when they receive one faulty AIRE copy from each parent. NCBI+2JCI Insight+2

Other names

APECED is known by several names that all describe the same condition. The most common alternate name is Autoimmune Polyglandular Syndrome type 1 (APS-1). You may also see autoimmune polyendocrinopathy syndrome type 1, Whitaker syndrome, or older terms such as autoimmune polyendocrinopathy candidiasis ectodermal dystrophy written out in full. Using “APECED” or “APS-1” is standard in medical articles. Orpha.net+1

Types

Doctors sometimes describe “types” or patterns based on what shows up first and which organs are involved. These aren’t strict, separate diseases, but they help plan care.

• Classic triad–predominant APECED. Two of the “big three” (chronic Candida, hypoparathyroidism, adrenal insufficiency) appear early—this is enough to make the diagnosis in most clinics. JCI Insight

• Atypical or non-triad–predominant APECED. People first show other autoimmune problems (for example, autoimmune hepatitis, intestinal malabsorption, or lung inflammation) before the triad becomes obvious. This can delay diagnosis. Frontiers+1

• Population founder variants. Certain families or regions (Finnish, Sardinian, Iranian Jewish communities) have shared AIRE changes (“founder mutations”) and recognizable clusters of features. This helps local doctors think of APECED sooner. Frontiers

• Dominant-negative AIRE variants (rare). Some families have single-copy AIRE changes that act in a dominant way and cause APECED-like disease with different severity; these are less common than classic recessive APECED. Frontiers

Causes

In APECED, the root cause is AIRE gene malfunction. Below are 20 concrete, plain-language “causes” that together explain how and why disease appears and varies among people.

1. Biallelic loss-of-function AIRE variants. Two broken AIRE copies remove central tolerance and allow self-reactive T cells to survive. Frontiers+1

2. Failed “self-antigen display” in the thymus. AIRE usually turns on many tissue-specific genes in thymic cells; without it, the immune system never learns those are “self.” PMC

3. Escape of self-reactive T cells. Harmful T cells leave the thymus and later attack organs like parathyroids, adrenals, skin, and liver. Frontiers

4. Autoantibodies against cytokines (IL-17/IL-22). These block key antifungal defenses and make chronic Candida infections likely. PMC

5. Autoantibodies against type I interferons (IFN-ω, IFN-α). These are very common in APECED and are useful diagnostic markers. JCI Insight

6. Autoantibodies against endocrine enzymes (e.g., 21-hydroxylase). These target adrenal steroid-making pathways and lead to Addison’s disease. NCBI

7. Autoantibodies against calcium-sensing or parathyroid targets. These interfere with parathyroid function and set up hypocalcemia. NCBI

8. Autoimmunity against enamel/ectodermal structures. This explains enamel hypoplasia, nail dystrophy, keratitis, alopecia, and vitiligo. NCBI

9. Founder mutations in certain populations. Shared AIRE changes in small communities increase family risk. Frontiers

10. Consanguinity. Parents related by blood raise the chance a child inherits the same AIRE change from both sides. National Organization for Rare Disorders

11. Genetic modifiers beyond AIRE. Other immune genes may shape which organs are targeted and when, changing severity between relatives. Frontiers

12. Dominant-negative AIRE variants (rare path). A single altered AIRE copy interferes with the normal one and causes disease in some families. Frontiers

13. Breaks in thymic structure/function. When medullary thymic epithelial cells (mTECs) don’t mature normally, tolerance training fails. Annual Reviews+1

14. Skewed Th17 immunity. Blocking IL-17/IL-22 weakens mucosal antifungal immunity and invites persistent Candida. PMC

15. Broad autoantibody “signature.” Diverse autoantibodies signal multi-organ risk and help doctors predict future problems. JCI Insight

16. Environmental exposures acting on unprotected tissues. Ordinary infections or stressors can unmask fragile organ systems in AIRE deficiency. (Inference consistent with reviews.) Frontiers

17. Immune attack on GI tract. Autoimmunity against gut and liver causes diarrhea, malabsorption, and hepatitis in many patients. Frontiers

18. Immune attack on lungs. APECED-related pneumonitis can appear and needs specific monitoring and therapy. Frontiers

19. B-cell participation. Autoantibody-producing B cells amplify tissue damage started by faulty T-cell tolerance. Frontiers

20. Delayed diagnosis. When the triad is not obvious early, organ damage may progress before the condition is recognized and treated. National Organization for Rare Disorders

Common symptoms and signs

1. Chronic mucocutaneous candidiasis (CMC). Recurrent thrush, mouth sores, angular cheilitis, or skin fold yeast infections that keep coming back despite treatment. This is often the first sign in childhood. JCI Insight

2. Symptoms of low calcium (hypoparathyroidism). Numbness around the mouth, tingling of fingers, muscle cramps, carpopedal spasm, and seizures in severe cases. Teeth may develop poorly over time. NCBI

3. Symptoms of adrenal insufficiency (Addison’s disease). Fatigue, weight loss, salt craving, dizziness on standing, and darkening of skin creases or gums; adrenal crisis can be life-threatening. NCBI

4. Enamel hypoplasia and dental problems. Thin or pitted enamel, early cavities, and tooth sensitivity that begin in childhood. NCBI

5. Nail changes and hair loss. Nail ridging or dystrophy and patchy hair loss (alopecia areata) are frequent ectodermal findings. NCBI

6. Skin color changes. Light patches (vitiligo) or darker areas (from Addison’s) are common visible clues. NCBI

7. Eye surface irritation. Dry, painful, light-sensitive eyes from autoimmune keratitis may lead to vision problems if untreated. NCBI

8. Chronic diarrhea and malabsorption. Poor weight gain in children, bloating, nutrient deficiencies, and anemia from autoimmune gut disease. Frontiers

9. Autoimmune hepatitis. Tiredness, jaundice, elevated liver enzymes; can progress without early treatment. Frontiers

10. Premature ovarian insufficiency. Early loss of periods, infertility, and low estrogen symptoms in females. NCBI

11. Thyroid problems. Underactive (hypothyroidism) or, less often, overactive thyroid leads to weight, energy, and temperature changes. NCBI

12. Type 1 diabetes (some patients). Thirst, frequent urination, weight loss, and high blood sugars due to pancreatic autoimmunity. NCBI

13. Lung inflammation (pneumonitis). Cough, breathlessness, and abnormal chest scans; this needs specific immunomodulatory care. Frontiers

14. Anemia and B12 deficiency. Fatigue and pallor from autoimmune gastritis or poor absorption; intrinsic factor antibodies may be present. NCBI

15. General autoimmune “flares.” Periods of worsening symptoms when one or more organs become inflamed, often triggered by illness or stress. Frontiers

Diagnostic tests

A) Physical exam (bedside observations)

1. Full skin, hair, and nail check. Doctors look for vitiligo, hyperpigmentation, alopecia, nail dystrophy, and rashes that suggest APECED. NCBI

2. Oral exam for thrush and enamel defects. White plaques that scrape off, fissured tongue corners, and enamel thinning are common clues. JCI Insight

3. Vital signs and orthostatic blood pressure. A big drop in blood pressure on standing hints at adrenal insufficiency. NCBI

4. Chvostek’s sign. Tapping the facial nerve causes facial muscle twitching when calcium is low. NCBI

5. Trousseau’s sign. Inflating a blood pressure cuff can trigger carpal spasm in hypocalcemia. NCBI

B) Manual/office tests (simple, non-lab checks)

6. Point-of-care glucose. Screens for diabetes if symptoms appear; high sugars prompt full workup. NCBI

7. Schirmer test for dry eyes. Measures tear production when keratitis or severe ocular dryness is suspected. NCBI

8. Fungal microscopy/culture from lesions. A quick KOH prep or culture confirms Candida in mouth or skin. PMC

9. Peak flow or simple spirometry. Tracks breathing if lung involvement is suspected before full pulmonary tests. Frontiers

C) Laboratory and pathological tests

10. Serum calcium, phosphate, magnesium, and PTH. Low calcium with inappropriately low PTH supports hypoparathyroidism. NCBI

11. Morning cortisol and ACTH (± cosyntropin test). Low cortisol with high ACTH confirms primary adrenal insufficiency. NCBI

12. Thyroid function (TSH, free T4) with thyroid autoantibodies. Screens for autoimmune thyroid disease. NCBI

13. Fasting glucose, HbA1c, and islet autoantibodies. Looks for type 1 diabetes and future risk when positive. NCBI

15. Liver enzymes and autoimmune liver antibody panel. Screens for autoimmune hepatitis when symptoms or labs suggest it. Frontiers

16. APECED-specific autoantibodies (anti–IFN-ω/α, anti-IL-17/IL-22). Very helpful markers that strongly point to APECED. JCI Insight+1

17. 21-hydroxylase antibodies and other organ-specific antibodies. Predict or confirm adrenal, ovarian, or other endocrine autoimmunity. NCBI

18. Genetic testing of the AIRE gene. Sequencing and deletion/duplication testing confirm the diagnosis and support family counseling. National Organization for Rare Disorders+1

D) Electrodiagnostic tests

19. Electrocardiogram (ECG). Low calcium can prolong the QT interval and cause dangerous rhythms; ECG helps monitor this. NCBI

20. EEG or nerve studies when indicated. Seizures from severe hypocalcemia may need EEG; neuropathy is uncommon but can be checked with nerve conduction if symptoms suggest it. NCBI

E) Imaging tests (often used “as needed”)

• Dental panoramic X-ray. Shows enamel hypoplasia and dental issues for planning care. NCBI

• Chest CT or X-ray. Evaluates lung inflammation (APECED pneumonitis) if cough or breathlessness persists. Frontiers

• Abdominal ultrasound/CT (selected cases). Looks at liver disease or other abdominal organ problems if labs are abnormal. Frontiers

• Bone density (DXA) and skeletal films when needed. Long-standing hypocalcemia or steroid therapy changes bone health; DXA helps track this. NCBI

• Ophthalmic slit-lamp exam (not imaging, but essential). Detects keratitis early to protect vision. NCBI

Non-pharmacological treatments (therapies & others)

When to see a doctor (right away)

See a clinician immediately for fever, vomiting, severe weakness, confusion, very low blood pressure, or darkening skin—these can signal adrenal crisis, which is a medical emergency. Also seek urgent care for muscle cramps or seizures (possible severe hypocalcemia), chest pain with swallowing or inability to swallow (severe esophageal disease), or new bleeding lesions in the mouth or throat. Oxford Academic+1

---

What to eat and what to avoid

Aim for a balanced diet with steady calcium intake divided through the day (dairy or fortified alternatives) and adequate protein and calories. Limit very high-oxalate foods if urine calcium is high (e.g., large amounts of spinach, rhubarb, beets, nuts) to lower stone risk. Avoid alcohol/tobacco; choose soft, non-spicy foods during esophagitis flares. Hydrate well and add salt if your Addison plan calls for it, especially in heat. Always individualize with your endocrinology/dietitian team. Society for Endocrinology+1

Frequently asked questions

1) Is APECED curable?
No cure yet; treatment manages each affected organ and prevents complications. Research aims to restore AIRE-driven tolerance in the future. Lippincott Journals

2) Why do I keep getting thrush?
AIRE defects impair antifungal immunity (especially IL-17 pathways), so Candida can persist; antifungals and good oral care help. PMC

3) Do I need lifelong medicines?
Usually yes for endocrine failures (steroids, fludrocortisone, calcium/vitamin D), and intermittently for infections or organ inflammation. Oxford Academic+1

4) Can antifungals be taken for a long time?
Sometimes chronic suppression is needed; doctors monitor liver tests, interactions, and resistance. IDSA

5) Why is endoscopy suggested?
Long-standing esophageal candidiasis raises squamous cell cancer risk; endoscopy finds early changes treatable sooner. Frontiers

6) Will my children have APECED?
It is autosomal recessive: if you and your partner are carriers, each pregnancy has a 25% chance of APECED. Genetic counseling helps. BioMed Central

7) Are live vaccines safe?
Discuss with your specialist, especially if you receive immunosuppressants; most routine non-live vaccines are encouraged. Frontiers

8) How quickly should I treat vomiting or fever?
Follow sick-day rules and use emergency steroids; seek urgent care to prevent adrenal crisis. Endocrine Society

9) Can I exercise?
Yes, with hydration and salt planning and stabilized calcium/steroid regimens; start gradually. Endocrine Society

10) Why is my dentist part of the team?
Dental care lowers Candida burden and protects enamel, reducing pain and cancer risk. Frontiers

11) Are IL-17-blocking drugs used?
They can worsen candidiasis; in APECED the problem already involves IL-17 pathway autoantibodies, so these drugs are not used for CMC. PMC

12) Can thyroid, liver, or lungs be affected later?
Yes. New autoimmune problems can appear over time, so regular screening is important. Frontiers

13) Do PPIs treat CMC?
No—they help symptoms/erosions; antifungals treat the yeast. Use PPIs only as needed and briefly. IDSA

14) What lab targets matter in HypoPT?
Keep calcium in the low-normal range, avoid high urine calcium, and maintain vitamin D sufficiency—under specialist guidance. Society for Endocrinology

15) Where can I learn more in one place?
See recent reviews and patient resources from immunology/endocrine groups that summarize genetics, diagnosis, and care. PMC+1
