Abstract
Autoimmune polyglandular syndrome (APS) is a rare group of immune-mediated disorders, which are typically, but not exclusively, related to the presence of endocrine abnormalities. APS type 2 is the most common subtype of the syndrome, more often observed in adulthood, with a characteristic clinical triad, which includes adrenal insufficiency, autoimmune thyroiditis and diabetes mellitus type 1. Adrenal insufficiency is an essential and necessary clinical manifestation of the syndrome, as it is observed in 100 % of the cases, while it can be accompanied by hyperchloremic metabolic acidosis. Herein, we present a 23 years-old patient with adrenal insufficiency in the context of autoimmune polyglandular syndrome type 2 with coexisting autoimmune thyroiditis and metabolic acidosis with an increased anion gap attributed to prolonged malnutrition. Additionally, we analyze the main clinical features of adrenal insufficiency, which is a central component of autoimmune polyglandular syndrome; highlight characteristics that differentiate the major APS subtypes.

Abstract
AIM OF THE STUDY The primary aim of the study was to evaluate the differences in metabolic control and chronic microvascular complications in patients with type 3 autoimmune polyglandular syndrome (APS3), compared to type 1 diabetes mellitus (T1DM) alone. Secondary aims were to evaluate the age of autoimmune thyroid disease (AIT) onset and the effects of levothyroxine treatment on metabolic control in patients with APS3. MATERIAL AND METHODS We retrospectively reviewed 276 patients with T1DM alone and 214 patients with APS3 and evaluated clinical and metabolic parameters and microvascular complications. RESULTS Patients with T1DM showed a longer duration of diabetes (p = 0.001) and lower age of diabetes onset (p = 0.020) compared to patients with APS3. Female gender (p = 0.001) and microalbuminuria (p = 0.006) were significantly more frequent in patients with APS3 compared to T1DM. In addition, patients with APS3 showed higher AIT onset frequency in the 16-30 quartile age-range. Furthermore, APS3 patients treated with levothyroxine showed significantly better HbA1c values than non-treated patients (p = 0.001). CONCLUSIONS We found that patients with APS3 showed positive microalbuminuria, earlier than T1DM. Patients with APS3 showed higher frequency of AIT age of onset in the 16-30 age-range and those treated with levothyroxine had better metabolic control, than untreated ones.

Abstract
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. Patient developed sunset glow fundus with alopecia, poliosis and vitiligo and a diagnosis of complete VKH with APECED was made. CONCLUSION APECED is a rare endocrine disorder and has been reported to be associated with VKH twice. Likewise, VKH is commonly present in much older patients; this is the first time ever to be diagnosed in a two-year-old child.

Abstract
PURPOSE to describe a clinical case of ocular sarcoidosis in a patient with Autoimmune Polyglandular Syndrome Type 2 (APS-2). METHODS an 86-year-old female diagnosed with APS-2 was referred to our uveitis department with rapid visual loss in her left eye during a 3-month period. Her best-corrected visual acuity (BCVA) was counting fingers in her left eye (OS) and 20/40 in her right eye (OD). Slit-lamp biomicroscopy was unremarkable OD but revealed granulomatous keratic precipitates OS. Fundoscopy revealed bilateral optic disc oedema and +2 and 4+ vitritis (SUN classification) in her OD and OS, respectively. RESULTS the patient underwent chest X-Ray which revealed bilateral hilar lymphadenopathy and fibrosis. On high-resolution computed tomography of the lungs, ground-glass opacities were visible, and a diagnosis of ocular sarcoidosis was presumed. After exclusion of infectious diseases, the patient was treated with methotrexate and oral corticosteroids and there was substantial improvement of the optic nerve oedema and vitritis. At the most recent visit, 2 years later, OS BCVA was 20/50. CONCLUSION There may be an association between ocular sarcoidosis and APS or other autoimmune disorders.

Abstract
A 52-year-old Japanese woman developed type 1 diabetes mellitus (type 1 DM) at 41 years old. She became complicated with Hashimoto's disease and showed swelling of both submandibular glands, which was diagnosed as IgG4-related disease (IgG4-RD). This is a rare case of a Japanese patient with autoimmune polyglandular syndrome type 3A (APS-3A) coexisting with autoimmune thyroid disease (AITD) and type 1 DM complicated by IgG4-RD. Bilateral submandibular gland resection was successfully performed without steroid therapy. We discuss the possibility that the immunological pathogenic mechanisms of APS-3A and IgG4-RD are related.

Abstract
A 45-year-old female presented with unprovoked recurrent venous thromboembolism (VTE), in unusual sites, and pancytopenia, posing a complex diagnostic challenge. Work-up for inherited thrombophilia, antiphospholipid syndrome (APLS) and paroxysmal nocturnal haemoglobinuria were unremarkable. Investigations revealed autoimmune thyroid disease, and a mixed iron/vitamin B12 deficiency due to pernicious anaemia and resultant atrophic gastritis. Hyperhomocysteinaemia due to vitamin B12 deficiency was identified as a potential contributor to her recurrent VTE. This case highlights the unusual initial presentation of autoimmune polyendocrinopathy syndrome type 3B (APS-3B) with recurrent thromboembolism, and emphasises the importance of considering hyperhomocysteinaemia in unprovoked and atypical VTE cases.

Abstract
PURPOSE Autoimmune polyglandular syndrome Type 1 (APS-1) is a rare autosomal recessive disorder caused by defects in the autoimmune regulator (AIRE) gene. Patients are generally diagnosed at ages between five and fifteen years when they exhibit three or more manifestations, most typically mucocutaneous candidiasis, autoimmune Addison's disease, and hypoparathyroidism. Our study aims to report the first case of a Chinese APS-1 patient, presented with LCA as the initial and essential clinical feature of this rare syndrome. METHODS Detailed medical and family history were recorded for the patient. Also, the comprehensive ophthalmological examinations were conducted. Whole exome sequencing (WES) was applied to screen pathogenic variants. Sanger sequencing validation and segregation analysis were further performed for confirmation. RESULTS A 3-year-old boy with severely impaired vision and initially referred as LCA. However, with a detailed history review, oral candidiasis, dental enamel hypoplasia, and nail candida infection were revealed. Moreover, genetic analysis revealed the homozygous c.769C>T (p.R257X) in AIRE gene (NM_000383.3) as the causative variant. CONCLUSION We presented one case diagnosed with APS-1 based on clinical characteristics and genetic analysis. Our study demonstrated that LCA could serve as a warning sign for APS-1 and a potential trigger of early screening, which might prevent life-threatening complications.

Abstract
Purpose Autoimmune polyendocrine syndrome (APS) is a rare immune-endocrinopathy characterized by the failure of at least two endocrine organs. Clinical characteristics have mainly been described in the Western population. This study comprehensively analyzed the demographic and clinical manifestations of APS II and APS III in Taiwan. Methods Patients aged ≥20 years with a diagnosis of APS II or APS III in ten hospitals between 2001 and 2021 were enrolled. The clinical and serological characteristics of the patients were retrospectively reviewed. Results Among the 187 enrolled patients (45 men and 142 women); only seven (3.7%) had APS II, while the others had APS III. Fifty-five patients developed hyperthyroidism and 44 patients developed hypothyroidism. Men were diagnosed with APS at a younger age than women (16.8 vs 27.8 years old, P = 0.007). Most patients were initially diagnosed with type 1 diabetes mellitus. There was a positive correlation between age at diagnosis and the likelihood of developing thyroid dysfunction. For every year older patients were diagnosed with APS III, the risk of developing hyperthyroidism increased by 3.6% (P = 0.002), and the risk of developing hypothyroidism increased by 3.7% (P = 0.035). Positive anti-parietal cell antibodies (APCA) were associated with a higher risk of anemia in patients with APS III (P < 0.001). Conclusion This study provides the most comprehensive analysis of APS II and APS III in Asia. The percentage of patients with APS II was significantly lower than in the Western population. A second autoimmune endocrinopathy may develop several years after the first one. APCA examination is valuable when evaluating anemia in patients with APS.

Abstract
Ameloblasts are specialized epithelial cells in the jaw that have an indispensable role in tooth enamel formation-amelogenesis1. Amelogenesis depends on multiple ameloblast-derived proteins that function as a scaffold for hydroxyapatite crystals. The loss of function of ameloblast-derived proteins results in a group of rare congenital disorders called amelogenesis imperfecta2. Defects in enamel formation are also found in patients with autoimmune polyglandular syndrome type-1 (APS-1), caused by AIRE deficiency3,4, and in patients diagnosed with coeliac disease5-7. However, the underlying mechanisms remain unclear. Here we show that the vast majority of patients with APS-1 and coeliac disease develop autoantibodies (mostly of the IgA isotype) against ameloblast-specific proteins, the expression of which is induced by AIRE in the thymus. This in turn results in a breakdown of central tolerance, and subsequent generation of corresponding autoantibodies that interfere with enamel formation. However, in coeliac disease, the generation of such autoantibodies seems to be driven by a breakdown of peripheral tolerance to intestinal antigens that are also expressed in enamel tissue. Both conditions are examples of a previously unidentified type of IgA-dependent autoimmune disorder that we collectively name autoimmune amelogenesis imperfecta.

Abstract
Background Glutamic acid decarboxylase (GAD) is the rate-limiting enzyme for the synthesis of gamma-aminobutyric acid (GABA), the major inhibitory neurotransmitter in the central nervous system. Antibodies against glutamic acid decarboxylase (GAD) are associated with various neurologic conditions described in patients, including stiff person syndrome, cerebellar ataxia, refractory epilepsy, and limbic and extra limbic encephalitis. While there are few case reports and research on anti-GAD65 antibody-associated encephalitis in adults, such cases are extremely rare in pediatric cases. Methods For the first time, we report a case of anti-GAD65-positive autoimmune encephalitis associated with autoimmune polyendocrine syndrome (APS) type II. We reviewed previously published pediatric cases of anti-GAD65 autoimmune encephalitis to discuss their clinical features, laboratory tests, imaging findings, EEG patterns, and prognosis. Case presentation An 8-year-old, male child presented to the outpatient department after experiencing generalized convulsions for twenty days. The child was admitted for epilepsy and had received oral sodium valproate (500 mg/day) in another center, where investigations such as USG abdomen and MRI brain revealed no abnormalities, however, had abnormal EEG with diffuse mixed activity in the left anterior middle prefrontal temporal region. On the follow-up day, a repeat blood test showed a very low serum drug concentration of sodium valproate hence the dose was increased to 750 mg/day. Then, the child experienced adverse effects including increased sleep, thirst, and poor appetite, prompting the parents to discontinue the medication. A repeat MRI showed increased signals on FLAIR sequences in the right hippocampus hence admitted for further management. The child's past history included a diagnosis of hypothyroidism at the age of 4, and receiving levothyroxine 75 mcg once daily. His parents are healthy with no history of any similar neurological, autoimmune, or genetic diseases, but his uncle had a history of epilepsy. At presentation, he had uncontrolled blood glucose levels with elevated HbA1c levels. Additionally, the serum and CSF autoantibodies were positive against the anti-GAD65 antibody with the titer of 1:100 and 1:32 respectively. The patient was managed with a mixed type of insulin regimen and received first-line immunotherapy (intravenous immunoglobulin, IVIG) for five consecutive days, followed by oral prednisone and sodium valproate as an antiepileptic drug. Upon achieving a favorable clinical outcome, the patient was discharged with oral medications. Results Among the 15 pediatric patients reported in this literature, nine presented with limbic encephalitis (LE), three with extralimbic encephalitis (ELE), and three with a combination of limbic and extralimbic encephalitis. Most of these cases exhibited T2-W FLAIR hyperintensities primarily localized to the temporal lobes in the early phase, progressing to hippocampal sclerosis/atrophy in the later phase on MRI. EEG commonly showed slow or spike waves on frontotemporal lobes with epileptic discharges. Prognostic factors varied among patients, with some experiencing persistent refractory seizures, type-1 diabetes mellitus (T1DM), persistent memory impairment, persistent disability requiring full assistance, and, in severe cases, death. Conclusion Our findings suggest that anti-GAD65 antibody-positive autoimmune encephalitis patients may concurrently present with other APS. Our unique case presented with multiple endocrine syndromes and represents the first reported occurrence in children. Early diagnosis and timely initiation of immunotherapy are crucial for improving clinical symptoms and reducing the likelihood of relapses or permanent disabilities. Therefore, emphasis should be placed on prompt diagnosis and appropriate treatment implementation to achieve better patient outcomes.

Abstract
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. We found AA occurred earlier in those with APECED than in the general population, was rarely the first sign of APECED, and the timing of AA onset did correlate with the timing of onset of vitiligo or hypothyroidism which also occurred at high rates and early age.

Abstract
Multiple endocrine neoplasia type 2A (MEN2A) is caused by germline pathogenic variants in the RET proto-oncogene and is characterized by medullary thyroid cancer (MTC), pheochromocytoma, and hyperparathyroidism. Autoimmune polyendocrine syndromes (APS) are defined as multiple endocrine gland insufficiency associated with loss of immune tolerance. APS type 2 (APS-2) consists of at least two of the following diseases: type 1 diabetes mellitus (T1DM), autoimmune thyroid disease, and Addison's disease. We describe the clinical, molecular, and biochemical findings of MEN2A, APS-2, and Kabuki syndrome (KS) in a 16-year-old male. Whole exome sequencing was performed to identify the genetic cause of the pheochromocytoma and syndromic features including facial dysmorphism, developmental delay, and epilepsy. RET pathogenic variant and KMT2D pathogenic variant were identified, and he was diagnosed with MEN2A and KS. This is the first case of association between MEN2 and APS in adolescence and the second proven case in humans. In addition, this is the first report of MEN2 and APS in KS.

Abstract
BACKGROUND Autoimmune disease, including autoimmune thyroid disease, with uncharacteristic symptoms can be due to additional severe disease. We report a life-threatening debut of autoimmune polyglandular syndrome type II (APS II) defined as Addison's disease combined with autoimmune diabetes and/or thyroid disease. PATIENT FINDINGS A 33-year-old male with newly diagnosed hypothyroidism was referred to a tertiary center due to fatigue and 20-kg rapid weight loss. Malignancy was excluded. After a gastroscopy, he developed Addison's crisis; he was admitted to our hospital and stabilized. Final diagnoses included Hashimoto's thyroiditis, Addison's disease, vitiligo, and pernicious anemia. Whole genome sequencing found no genetic variants associated with component diseases. Human leukocyte antigen typing revealed DR3/DR4 and DQ8/DQ2 heterozygosity associated with APS II. A patient with Hashimoto's thyroiditis and weight loss presented with Addison's crisis and was diagnosed with APS II. CONCLUSIONS Awareness of potential polyautoimmunity in clinical evaluation of patients with thyroid disease improves diagnosis and can be lifesaving.

Abstract
An adolescent female was evaluated for fatigue, anorexia and unintentional weight loss of 7 kg. Initial investigations revealed subclinical autoimmune thyroid dysfunction, which progressed to overt hypothyroidism necessitating thyroxine replacement. She had entered early puberty, but this did not appear to be progressing. A high index of suspicion for coexisting endocrinopathies resulted in a diagnosis of Addison's disease and consequently autoimmune polyglandular syndrome type 2 (Schmidt syndrome). While basal gonadotropins were normal, anti-Mullerian hormone was low and ovarian autoantibodies were positive, consistent with preclinical premature ovarian failure. Glucocorticoid and mineralocorticoid replacement were instituted. Puberty progressed and menarche was subsequently attained. Screening for other autoantibodies was undertaken; however, none are positive to date.

Abstract
A 35-year-old man experienced general fatigue and could not eat solid food because of nausea and vomiting. His weight abruptly decreased from 49 to 45 kg after 2 weeks. A detailed examination indicated superior mesenteric artery syndrome (SMAS) accompanied by acute-onset type 1 diabetes complicated by Graves' disease, referred to as autoimmune polyglandular syndrome type 3A (APS3A). Although SMAS has a good prognosis, some cases require emergency surgery, especially when complicated by gastric perforation. In our case, APS3A and SMAS developed rapidly and at approximately the same time, resulting in a cycle of mutual exacerbation.

Abstract
Autoantibodies that recognize extracellular proteins (the exoproteome) exert potent biological effects but are challenging to detect. Here, we developed rapid extracellular antigen profiling (REAP), a high-throughput technique for the comprehensive discovery of exoproteome-targeting autoantibodies. Patient samples are applied to a genetically barcoded yeast surface display library containing 2,688 human extracellular proteins. Antibody-coated yeast are isolated, and sequencing of barcodes is used to identify displayed antigens. To benchmark REAP's performance, we screened 77 patients with autoimmune polyglandular syndrome type 1 (APS-1). REAP sensitively and specifically detected both known and previously unidentified autoantibodies in APS-1. We further screened 106 patients with systemic lupus erythematosus (SLE) and identified numerous autoantibodies, several of which were associated with disease severity or specific clinical manifestations and exerted functional effects on cell signaling ex vivo. These findings demonstrate the utility of REAP to atlas the expansive landscape of exoproteome-targeting autoantibodies and their impacts on patient health outcomes.

Abstract
CONTEXT Autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED; also known as autoimmune polyendocrine syndrome type 1) has a severe, unpredictable course. Autoimmunity and disease components may affect fertility and predispose to maternal and fetal complications, but pregnancy outcomes remain unknown. OBJECTIVE To assess fetal and maternal outcomes and course of clinical APECED manifestations during pregnancy in women with APECED. DESIGN AND SETTING A multicenter registry-based study including 5 national patient cohorts. PATIENTS 321 females with APECED. MAIN OUTCOME MEASURE Number of pregnancies, miscarriages, and deliveries. RESULTS Forty-three patients had altogether 83 pregnancies at median age of 27 years (range, 17-39). Sixty (72%) pregnancies led to a delivery, including 2 stillbirths (2.4%) and 5 (6.0%) preterm livebirths. Miscarriages, induced abortions, and ectopic pregnancies were observed in 14 (17%), 8 (10%), and 1 (1.2%) pregnancies, respectively. Ovum donation resulted in 5 (6.0%) pregnancies. High maternal age, premature ovarian insufficiency, primary adrenal insufficiency, or hypoparathyroidism did not associate with miscarriages. Women with livebirth had, on average, 4 APECED manifestations (range 0-10); 78% had hypoparathyroidism, and 36% had primary adrenal insufficiency. APECED manifestations remained mostly stable during pregnancy, but in 1 case, development of primary adrenal insufficiency led to adrenal crisis and stillbirth. Birth weights were normal in >80% and apart from 1 neonatal death of a preterm baby, no serious perinatal complications occurred. CONCLUSIONS Outcome of pregnancy in women with APECED was generally favorable. However, APECED warrants careful maternal multidisciplinary follow-up from preconceptual care until puerperium.

Abstract
We present a case of a 41-year-old woman who was diagnosed with autoimmune polyendocrine syndrome type 1 (APS-1) at the age of 2. She developed severe anemia and was diagnosed with pure red cell aplasia (PRCA) and T-cell large granular lymphocyte leukemia at the age of 34. The pathogenesis of APS-1 is based on the presence of an inactive mutation in the autoimmune regulator gene on thymic medullary epithelial cells. It is thought that the autoimmune T cells generated by impaired negative selection in the thymus induce PRCA. The patient was treated with immunosuppressive therapy (ciclosporin, antithymocyte globulin, prednisolone, and cyclophosphamide) for a long time by her previous doctor. After a long period of remission and exacerbation, she became dependent on blood transfusion approximately at the age of 40 and was transferred to our hospital. At our hospital, alemtuzumab treatment resulted in the disappearance of large granular lymphocytes and improvement of anemia. We report this case as a valuable demonstration of the efficacy of alemtuzumab for treating PRCA associated with APS-1.

Abstract
CONTEXT Hypokalemia is a common finding in patients with autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED) but its exact cause often remains unknown. OBJECTIVE To explore the prevalence and etiology of hypokalemia and the role of adrenal steroids therein in a cohort of patients with APECED. METHODS We performed a cross-sectional assessment and retrospective data collection on 44 Finnish patients with APECED to identify subjects with episodes of hypokalemia. Also 68 healthy matched controls attended the cross-sectional evaluation. Factors associating with a tendency for hypokalemia were analyzed by reviewing medical records during 1960-2021 and performing a cross-sectional analysis of serum adrenal steroids. RESULTS In total 14 of the 44 APECED patients (32%) had episodes of hypokalemia; 2 presented with hypokalemia at cross-sectional evaluation and 12 had a history of hypokalemia before the cross-sectional evaluation. Hypokalemic episodes started at the median age of 14.1 years; 12/14 (86%) had primary adrenal insufficiency (PAI). The median number of hypokalemic periods per year was 0.3 (range 0.04-2.2); the frequency correlated positively with the number of clinical APECED manifestations at the time of cross-sectional evaluation (r=0.811, p<0.001). Etiologies of hypokalemia varied but episodes often occurred when new clinical manifestations developed and during hospitalizations. Three patients had kidney defects, also associated with electrolyte imbalances. Severity of hypokalemia varied (range 2.2-3.2 mmol/L), but no severe complications were observed. At cross-sectional evaluation, patients with PAI (n = 30) had significantly lower median plasma potassium and higher sodium concentration than controls, suggesting that fludrocortisone treatment contributed to hypokalemia. Detailed analysis of adrenal steroids provided no conclusive differences between patients with and without episodes of hypokalemia. CONCLUSIONS In APECED, hypokalemia is common and varies in terms of frequency, etiology, and severity. PAI and kidney disease predispose to hypokalemia. In addition, hypokalemic periods seem to be more common in patients with more severe phenotype of APECED.

Abstract
We report a case of a lady who had polyglandular autoimmune syndrome type II (hypothyroidism, Addison's disease, vitiligo), who completed a successful pregnancy. Addison's disease (AD) was confirmed by the presence of anti-adrenal antibodies and hyponatremia. The patient had pre-pregnancy counselling about the need of antepartum, intrapartum and postpartum steroids. The pregnancy was managed with endocrinologist and obstetrician inputs, and appropriate follow-ups. Her pregnancy was completed with no complications. Labour was complicated by hyponatremia, secondary to nausea and vomiting that needed anaesthesia consultation. The patient delivered by vaginal delivery with no perinatal or early neonatal complications. The fetal growth was at 90th centile. Management in pregnancy, labour and postnatal period requires multidisciplinary care by the endocrinologist, obstetrician, midwife, anaesthetist and neonatologist. Key Words: Addison's disease, Hypothyroidism, Hyponatremia, Labour, Pregnancy.

Abstract
Type 1 diabetes mellitus (T1DM) is often complicated with some other autoimmune disorders. The complication of various autoimmune disorders is known as autoimmune polyglandular syndrome (APS). Once autoimmune thyroid disease develops, various autoimmune diseases can also occur. Such phenomena are classified as APS types 3A to 3D. In this report, we show the onset of T1DM in a patient with ulcerative colitis (UC) and Sjogren's syndrome. The most important and interesting point in this case is that, if we did not check her thyroid-associated antibodies, we could not have diagnosed her as APS. From the data of this case, we assumed that the patient suffered from APS type 3A, 3B, and 3D variants. This case pointed out very clearly the importance of testing for thyroid-associated antibodies under various autoimmune disease conditions even if the thyroid hormone levels are euthyroid. Moreover, based on the strong linkage between inflammatory bowel disease and T1DM and the compatibility with both T1DM and APS type 3, we think it is possible that Hashimoto's disease is present under complicated conditions together with UC and T1DM. It would be important to repeatedly check for thyroid-associated antibodies even in euthyroid patients, especially under various autoimmune disease conditions.
