autoimmune polyendocrinopathy- candidiasis-ectodermal dystrophy

We report a long-term remission in candidiasis in a 57-year-old Finnish female with autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED) suffering from recurrent oral, esophageal, gastric, vaginal, and anal candidiasis since childhood. Candidiasis treatment with antifungal medicines fluconazole, itraconazole, posaconazole, voriconazole, caspofungin, nystatin or amphotericin-B during 2008-2021 had variable effects and intermittent development of antifungal resistance and hospital periods. The patient started using fermented lingonberry juice (FLJ) as a mouth rinse daily in April 2021...

CONTEXT: Subjects with autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED) have subnormal adult height. There are several potential APECED-related risk factors for suboptimal height attainment during childhood. OBJECTIVE: To determine the growth patterns in children with APECED. DESIGN: Retrospective longitudinal study. SETTING: The Finnish national APECED cohort. PATIENTS: 59 children with APECED...

Autoimmune-Polyendocrinopathy-Candidiasis-Ectodermal Dystrophy (APECED) is a monogenic autoimmune disease most often resulting from biallelic loss-of-function variants in the autoimmune regulator ( AIRE ) gene. Although typically characterized by the classic triad of chronic mucocutaneous candidiasis, hypoparathyroidism, and adrenal insufficiency, we have recently reported that the clinical spectrum of the syndrome is far broader that previously described and that incorporation of an adjunct triad of APECED rash, autoimmune enteritis-associated intestinal dysfunction, and enamel hypoplasia in the classic triad manifestations could lead to earlier diagnosis...

Autoimmune-polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED) is a monogenic inborn error of autoimmunity that is caused by damaging germline variants in the AIRE gene and clinically manifests with multiple autoimmune diseases in patients. Studies on the function of the AIRE gene, discovered in 1997, have contributed to fundamental aspects of human immunology as they have been important in understanding the basic mechanism of immune balance between self and non-self. This chapter looks back to the discovery of the AIRE gene, reviews its main properties, and discusses the key findings of its function in the thymus...

In the last 20 years, discoveries about the autoimmune regulator (AIRE) protein and its critical role in immune tolerance have provided fundamental insights into understanding the molecular basis of autoimmunity. This review provides a comprehensive overview of the effect of AIRE on immunological tolerance and the characteristics of autoimmune diseases in Autoimmune Polyendocrinopathy-Candidiasis-Ectodermal Dystrophy (APECED), which is caused by biallelic AIRE mutations. A better understanding of the immunological mechanisms of AIRE deficiency may enlighten immune tolerance mechanisms and new diagnostic and treatment strategies for autoimmune diseases...

PURPOSE: To present a case of Vogt Koyanagi Harada (VKH) associated with autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy syndrome (APECED) in a two-year-old. CASE PRESENTATION: A two-year-old type 1 diabetic with hypothyroidism presented with impaired fixation. Ocular examination revealed right vitritis, choroiditis, a hyperemic disc, and an area of exudative detachment. At the same time, there was no fundus view in the left eye, and ultrasonographic assessment revealed vitritis and a thickened choroid...

Autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED), or polyglandular autoimmune syndrome type 1 (PAS-1/APS-1), is a rare autosomal recessive disorder linked to mutations in the autoimmune regulator (AIRE) gene. This review provides a detailed analysis of cutaneous manifestations in APECED, focusing on chronic mucocutaneous candidiasis (CMC), alopecia areata (AA), and vitiligo. The classic triad of hypoparathyroidism, adrenal insufficiency, and CMC serves as a diagnostic cornerstone. However, the varied clinical spectrum of APECED, particularly its cutaneous presentations, poses a diagnostic challenge...

BACKGROUND: Autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED, also called APS-1) is an inborn error of immunity with clear signs of B cell autoimmunity such as neutralising anti-IFN antibodies. In APECED, mutations in the AIRE gene impair thymic negative selection of T cells. The resulting T cell alterations may then cause dysregulation of B cells responses. However, no analysis of interactions of T and B cells in the germinal centres in patients' secondary lymphatic tissues has been reported...

Studies of the monogenic autoimmune disease immunodysregulation polyendocrinopathy enteropathy X-linked syndrome (IPEX) have elucidated the essential function of the transcription factor FOXP3 and thymic-derived regulatory T cells (Tregs ) in controlling peripheral tolerance. However, the presence and the source of autoreactive T cells in IPEX remain undetermined. Here, we investigated how FOXP3 deficiency affects the T cell receptor (TCR) repertoire and Treg stability in vivo and compared T cell abnormalities in patients with IPEX with those in patients with autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy syndrome (APECED)...

Autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED) is an inborn error of immunity, resulting from variation in the autoimmune regulator gene ( AIRE ). Pathogenic variants in the AIRE gene result in autoimmunity typically involving endocrine organs with nonendocrine organs less commonly affected. Hepatitis associated with APECED has emerged as a potentially fatal complication with higher reported prevalence in the Americas. We describe a case of a 3-year-old boy presenting with hepatitis from APECED without classical clinical diagnostic criteria...

Autoimmune polyendocrine syndrome type 1 (APS-1), also referred to as autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED), is a rare monogenic autosomal recessive autoimmune disease. It is caused by mutations in the autoimmune regulator ( AIRE ) gene. APS-1 is diagnosed clinically by the presence of two of the three major components: chronic mucocutaneous candidiasis (CMC), hypoparathyroidism, and primary adrenocortical insufficiency. A 3.3-year-old girl was presented with a carpopedal spasm to the pediatric emergency clinic...

One hallmark of some autoimmune diseases is the variability of symptoms among individuals. Organs affected by the disease differ between patients, posing a challenge in diagnosing the affected organs. Although numerous studies have investigated the correlation between T cell antigen receptor (TCR) repertoires and the development of infectious and immune diseases, the correlation between TCR repertoires and variations in disease symptoms among individuals remains unclear. This study aimed to investigate the correlation of TCRα and β repertoires in blood T cells with the extent of autoimmune signs that varies among individuals...

Primary immunodeficiency disorders (PIDs) are a heterogeneous group of genetic conditions profoundly impacting immune function. The investigation spans various PID categories, offering insights into their distinct pathogenic mechanisms and clinical manifestations. Within the adaptive immune system, B-cell, T-cell, and combined immunodeficiencies are dissected, emphasizing their critical roles in orchestrating effective immune responses. In the realm of the innate immune system, focus is directed toward phagocytes and complement deficiencies, underscoring the pivotal roles of these components in initial defense against infections...

Autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED) is an inherited disorder of immunity which leads to increased risk for mucocutaneous candidiasis and multiorgan autoimmune disease. While alopecia areata (AA) has been described in some patients with APECED, the extent and timing of AA is not well established and extent and timing of concomitant vitiligo and hypothyroidism has not been described. We evaluated an APECED cohort followed at the National Institutes of Health for the timing of development of associated diseases...

INTRODUCTION: Autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED) syndrome is a rare monogenic disease determined by biallelic mutations in AIRE gene, which encodes a transcription factor essential for central immune tolerance. Classic diagnosis is determined by the presence of two of the main APECED clinical diseases: chronic mucocutaneous candidiasis, chronic hypoparathyroidism, and Addison's disease. Non-endocrine autoimmunity, involving the liver, intestine, eyes, and kidneys, is generally reported in a minority of European patients, while American APECED patients have a higher tendency of developing organ-specific non-endocrine manifestations early in life...

Autoimmune polyendocrinopathy candidiasis ectodermal dystrophy (APECED) is a multisystemic rare genetic disorder characterised by abnormalities of the immune system. We report the ocular features of APECED in two siblings of an Indian family, out of four who are still living. The ocular features of this disorder primarily included madarosis, refractive error, heterochromia, corneal opacity and peripheral retinal pigment epithelium degeneration. There is marked phenotypical heterogeneity in this disorder. We found differences even between monozygotic twins...

Homozygous mutations in the autoimmune regulator (AIRE) gene that cripple thymic negative selection of autoreactive T cells result in autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED). However, how AIRE regulates the T cell response against foreign pathogens is not well understood. Here, we observed comparable primary CD8+ T cells but a markedly reduced memory T cell population and protective function in Aire-/- mice compared with wild-type after infection with a strain of recombinant Listeria monocytogenes...

BACKGROUND: APECED is a syndrome characterized by autoimmune polyendocrinopathy, candidiasis, and ectodermal dystrophy. The most observed clinical findings are chronic mucocutaneous candidiasis, hypoparathyroidism, and autoimmune adrenal insufficiency. Case Presentation . A three-year-old male patient was admitted with classical signs of juvenile idiopathic arthritis and treated with nonsteroidal anti-inflammatory drugs. During follow-up, signs of autoimmunity, candidiasis, nail dystrophy, and onychomycosis were observed...

SUMMARY: Autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED) is a rare autosomal recessive inherited syndrome caused by mutations in autoimmune regulator (AIRE) gene. The three clinical components of this syndrome are mucocutaneous candidiasis, hypoparathyroidism, and primary adrenal insufficiency. In addition to these frequent symptoms, many other components have been reported including gastrointestinal manifestations.We report a case of a 17-year-old Caucasian female patient diagnosed with APECED who presented with acute abdominal pain...
