FAQs

Hypoparathyroidism–Addison disease–mucocutaneous candidiasis syndrome is most widely known as Autoimmune Polyendocrine/Polyglandular Syndrome type 1 (APS-1) or Autoimmune Polyendocrinopathy–Candidiasis–Ectodermal Dystrophy (APECED). It also appears in the literature as Whitaker syndrome and candidiasis–hypoparathyroidism–Addison’s disease syndrome. All of these names describe the same rare, inherited autoimmune disease defined clinically by two or more features of the triad: chronic mucocutaneous candidiasis, hypoparathyroidism, and primary adrenal insufficiency (Addison disease). DermNet®+3Oxford Academic+3Orpha.net+3

APS-1 / APECED is a rare inherited autoimmune disease in which the body’s immune system mistakenly attacks several organs. The classic triad is: (1) chronic mucocutaneous candidiasis (yeast infections of the mouth, skin, nails), (2) hypoparathyroidism (very low parathyroid hormone causing low blood calcium), and (3) primary adrenal insufficiency (Addison disease) (damaged adrenal glands that cannot make cortisol and often aldosterone). APS-1 is usually caused by harmful changes in the AIRE gene and is passed in an autosomal recessive way (both copies changed). Other organs can also be affected over time. NCBI+1

APS-1/APECED is a genetic autoimmune disorder. A change (mutation) in a single immune-tuning gene called AIRE prevents the thymus from “teaching” developing immune cells how to ignore the body’s own tissues. As a result, self-reactive immune cells and characteristic autoantibodies appear and gradually attack several hormone-making glands (most often the parathyroids and adrenals) and the body’s skin/mucosal defenses against Candida yeast. Over time, people develop some combination of low calcium from hypoparathyroidism, cortisol deficiency from Addison disease, and recurrent or persistent Candida infections of the mouth, skin, nails, or esophagus. Other autoimmune problems (for example, enamel defects, alopecia, vitiligo, hepatitis, pernicious anemia) are common. PMC+2Oxford Academic+2

Types

Classic, recessive APS-1 (APECED). The usual form caused by biallelic (two-copy) loss-of-function AIRE mutations, presenting in childhood with chronic candidiasis and then hypoparathyroidism and/or Addison disease. PMC+1
Non-classic / atypical presentations. Some patients have one or no identifiable AIRE variants but show the serologic hallmark autoantibodies to type-I interferons (e.g., IFN-ω) and parts of the triad; they may present later or with fewer organs involved. JCI Insight
Dominant-negative AIRE variants. Rare heterozygous (one-copy) AIRE mutations can act dominantly, producing a milder, variable APS-1–like picture in some families. ScienceDirect
Population founder variants. Certain communities (Finnish, Sardinian, Iranian-Jewish) have signature AIRE mutations with higher disease incidence. Frontiers

Causes

In APS-1/APECED, “cause” mainly means immune tolerance failure from AIRE defects plus the specific autoantibodies and immune pathways that drive each component of the triad.

Biallelic AIRE loss-of-function (autosomal recessive) → central tolerance failure. PMC
Dominant-negative AIRE variants (rare) causing incomplete tolerance. ScienceDirect
Founder AIRE mutations in specific populations increasing risk (e.g., R257* in Finns). Frontiers
Impaired negative selection in the thymus → autoreactive T cells survive. PMC
Defective AIRE-driven expression of tissue antigens in thymic epithelial cells, weakening deletion of self-reactive T cells. PMC

Diagnostic tests

A) Physical examination (what a clinician looks for)

General inspection for skin/nail/mucosal Candida (white removable plaques, erythematous intertrigo, nail dystrophy). These are persistent/recurrent. Immune Deficiency Foundation
Signs of low calcium: muscle twitching, perioral tingling, or tetany during the visit. PMC
Hyperpigmentation and low blood pressure suggesting Addison disease. Oxford Academic
Dental and gum exam for enamel hypoplasia (pits/ridges; sensitivity) that can point toward APS-1. PMC
Eye exam clues (photophobia, keratitis) when patients report irritation or blurred vision. JCI Insight

B) Manual bedside maneuvers (simple office tests)

Trousseau sign: inflating a blood-pressure cuff above systolic pressure for 2–3 minutes may provoke carpopedal spasm—a classic sign of significant hypocalcemia. NCBI
Chvostek sign: tapping the facial nerve may cause facial muscle twitch. It exists in some healthy people and is neither very sensitive nor specific, so it supports but does not prove hypocalcemia. New England Journal of Medicine

C) Laboratory & pathological tests (the core of diagnosis)

Serum calcium (total and/or ionized) and albumin: low calcium confirms hypocalcemia; albumin helps correct total calcium. PMC
Parathyroid hormone (PTH): low or inappropriately normal PTH in the setting of hypocalcemia confirms hypoparathyroidism. PMC+1
Serum phosphate and magnesium: high phosphate is typical; low magnesium can mimic/worsen hypoparathyroidism and must be corrected. PMC
24-hour urinary calcium (and renal function) in chronic cases to monitor treatment safety (hypercalciuria risk). PMC

Mechanism: restores basal glucocorticoid action for energy, blood pressure, and stress response. Side effects: weight gain, glucose rise, mood changes if over-replaced; under-replacement causes fatigue and hypotension. Oxford Academic

2) Fludrocortisone (mineralocorticoid).
Dose: 0.05–0.2 mg daily, titrated to BP, potassium, renin. Purpose: replace aldosterone to maintain salt/water balance. Mechanism: increases renal sodium reabsorption. Side effects: edema, hypertension, low potassium if excessive. Endocrine Society

3) Emergency hydrocortisone (IM/IV).
Dose: 100 mg IM/IV at start of crisis, then 200 mg/24 h IV or 50 mg q6h. Purpose: treat adrenal crisis. Mechanism: rapid glucocorticoid effect stabilizes vessels and glucose. Side effects: transient hyperglycemia; benefit far outweighs risk. Society for Endocrinology

4) Calcium carbonate or citrate.
Dose: divided doses with meals per labs. Purpose: correct hypocalcemia in HypoPT. Mechanism: supplies absorbable calcium; citrate absorbs better with low stomach acid. Side effects: constipation, kidney stone risk if excessive. Wiley Online Library

5) Active vitamin D (calcitriol or alfacalcidol).
Dose: small divided doses, titrate to serum and urinary calcium goals. Purpose: enhance intestinal calcium absorption without PTH. Mechanism: bypasses kidney activation step. Side effects: hypercalcemia, hypercalciuria—need monitoring. Wiley Online Library

6) Magnesium repletion (e.g., magnesium citrate).
Dose: as needed to correct low Mg. Purpose: enable PTH secretion/action. Mechanism: cofactor for PTH physiology. Side effects: diarrhea at high doses. Wiley Online Library

7) Recombinant human PTH (where available).
Dose: individualized daily injections/infusion in selected HypoPT not controlled on calcium/Vit-D. Purpose: more physiologic calcium control and reduce calcium/Vit-D burden. Mechanism: replaces missing hormone. Side effects: hypercalcemia risk; specialized use. Wiley Online Library

8) Topical azoles (clotrimazole, ketoconazole) for skin/oral.
Dose: apply as directed; clotrimazole troches for oral thrush. Purpose: treat localized Candida. Mechanism: blocks fungal ergosterol synthesis. Side effects: local irritation; check interactions with oral azoles. IDSA

9) Oral fluconazole.
Dose: e.g., 100–200 mg/day for mucosal disease; adjust per site and duration. Purpose: first-line for many mucosal candidiasis cases. Mechanism: triazole antifungal blocking lanosterol 14-α-demethylase. Side effects: liver enzyme elevation, drug interactions (CYP). IDSA

10) Itraconazole / posaconazole (azole alternatives).
Dose: per formulation; monitor levels if needed. Purpose: for refractory or fluconazole-resistant Candida. Mechanism: azole class; broader spectrum. Side effects: interactions, hepatic effects; monitor QT. IDSA

11) Nystatin (oral suspension).
Dose: swish and swallow for oral thrush. Purpose: local therapy with minimal systemic absorption. Mechanism: binds ergosterol, forming pores. Side effects: GI upset; less effective for esophageal disease. IDSA

12) Echinocandins (caspofungin/micafungin/anidulafungin).
Dose: IV regimens for severe disease. Purpose: rescue in refractory mucosal/ invasive candidiasis. Mechanism: inhibits β-1,3-D-glucan synthesis in fungal cell wall. Side effects: infusion reactions, LFT changes. IDSA

FAQs

1) Is APS-1 the same as APS-2?
No. APS-1 is due to AIRE variants with the classic triad; APS-2 is a different adult-onset clustering (Addison, thyroid, type 1 diabetes) without AIRE mutations. Endocrine Society

2) Can APS-1 be cured?
There is no cure yet. Management replaces missing hormones, controls Candida, and monitors for new autoimmune issues—most people do well with good plans. NCBI

3) How is APS-1 diagnosed?
By clinical features, autoantibodies, and often AIRE genetic testing. PubMed

4) Why do I get so many yeast infections?
APS-1 affects mucosal antifungal immunity, so Candida overgrows more easily. Frontiers

5) What is adrenal crisis?
A life-threatening lack of cortisol during stress—treated with IM/IV hydrocortisone and fluids immediately. Society for Endocrinology

6) Do I take more steroids when ill?
Yes—follow sick-day rules from your team; this prevents crisis. Society for Endocrinology

7) Will calcium tablets be forever?
Many people with HypoPT need long-term calcium + active vitamin D, adjusted by labs; some are candidates for PTH therapy. Wiley Online Library

8) Are antifungals safe long-term?
They are effective but need supervision for drug interactions and liver tests; stewardship prevents resistance. IDSA

9) What about pregnancy?
Careful planning and stress-dose education are essential; endocrine teams adjust doses and monitor electrolytes. Oxford Academic

10) Should my family be tested?
Yes—genetic counseling helps identify carriers and at-risk relatives. Immune Deficiency Foundation

11) Can diet fix APS-1?
Diet supports therapy (calcium/magnesium/salt as advised) but does not replace hormone or antifungal treatments. Wiley Online Library

12) Can I exercise?
Yes—build gradually, hydrate, and follow salt guidance; carry your emergency steroid kit. Oxford Academic

13) Are vaccines OK?
Routine vaccines are recommended to reduce infection-triggered stress dosing. Society for Endocrinology
