APECED in children

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 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...

PURPOSE: Biallelic loss-of-function mutations of AIRE cause the autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED) syndrome. However, single nucleotide mutations may cause a milder phenotype. In this paper, we describe an unusual and mild phenotype in a mother and her two children (son and daughter) who carry a rare heterozygous mutation of AIRE. METHODS AND RESULTS: The son presented with alopecia and subclinical hypothyroidism due to Hashimoto's Thyroiditis (HT); the daughter had alopecia, vaginal mycosis, stomach pains and subclinical hypothyroidism due to HT; and the mother had alopecia, vaginal mycosis and stomach pains...

Autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED) is a rare monogenic autosomal recessive disorder caused by mutation in the autoimmune regulator (AIRE) gene. Patients usually are diagnosed at ages between 5 and 15 years when they show 3 or more manifestations, most typically mucocutaneous candidiasis, Addison's disease, and hypoparathyroidism. APECED-associated hepatitis (APAH) develops in only 10% to 40% of patients, with severity varying from subclinical chronic active hepatitis to potentially fatal acute liver failure (ALF)...

CONTEXT: The monogenic disorder autoimmune polyendocrine syndrome type 1 (APS-1) or autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED) manifests frequently with hypoparathyroidism, which requires treatment with oral supplementation with calcium and active vitamin D analogs. The majority of APS-1/APECED patients also suffer from intestinal malabsorption, which complicates the management of hypoparathyroidism and may lead to refractory severe hypocalcemia. In such situations, reliance on intravenous calcium carries a high risk of nephrocalcinosis and renal damage...

Objectives: To present a prospective report on the characteristics of autoimmune manifestations in patients with primary immunodeficient children registered in the Kuwait National PIDs Registry (KNPIDR). Methods: The data were obtained from the Kuwait National Primary Immunodeficiency Disorders Registry during the period of January 2004 to December 2019. Results: A total of 286 PID children were registered in KNPIDR during the study period with a predominance of immunodeficiencies affecting cellular and humoral immunity followed by combined immunodeficiencies with associated syndromic features and diseases of immune dysregulation...

Primary immune deficiencies are usually attributed to genetic defects and, therefore, frequently referred to as inborn errors of immunity (IEI). We subjected the genomic DNA of 333 patients with clinical signs of IEI to next generation sequencing (NGS) analysis of 344 immunity-related genes and, in some instances, additional genetic techniques. Genetic causes of the disease were identified in 69/333 (21%) of subjects, including 11/18 (61%) of children with syndrome-associated IEIs, 45/202 (22%) of non-syndromic patients with Jeffrey Modell Foundation (JMF) warning signs, 9/56 (16%) of subjects with periodic fever, 3/30 (10%) of cases of autoimmune cytopenia, 1/21 (5%) of patients with unusually severe infections and 0/6 (0%) of individuals with isolated elevation of IgE level...

BACKGROUND: Escherichia coli strains include both commensal and virulent clones distributed in different phylogenetic groups. Antimicrobial resistance is an increasingly serious public health threat at the global level and integrons are important mobile genetic elements involved in resistance dissemination. This paper aims to determine the phylogenetic groups and presence of class 1 (intl1) and 2 (intl2) integrons in E. coli clinical isolates from children with diarrhoea, and to associate these characteristics with their antimicrobial resistance...

BACKGROUND: Hypoparathyroidism is characterized by the absence or inadequately low circulating concentrations of the parathyroid hormone, resulting in hypocalcemia, hyperphosphatemia, and elevated fractional excretion of calcium in the urine. The use of activated vitamin D analogs and calcium supplements represent conventional therapy. Subcutaneous recombinant human parathormone [rhPTH(1-34)] has been proposed as a substitutive treatment, even to avoid side effects of vitamin D and calcium...

Early diagnosis of potentially life-threatening autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED) is crucial, but is often delayed due to the clinical heterogeneity of the disorder. Even in the absence of the classic disease triad of chronic mucocutaneous candidiasis, hypoparathyroidism, and adrenocortical insufficiency, a diagnosis of APECED should be considered in children who have hypoparathyroidism and chronic keratitis, with a past medical history showing a mild and transient Candida infection...

Type 1 diabetes mellitus (DM) and Graves' disease are autoimmune diseases, and a number of genetic factors, including HLA and CTLA-4 genes, have been reported to contribute to their etiology. The gene responsible for autoimmune polyendocrinopathy- candidiasis-ectodermal dystrophy (APECED) has been cloned and named the autoimmune regulator-1 (AIRE-1) gene. AIRE-1 protein is thought to be a transcription regulatory protein and to have a role in the maintenance of immunological tolerance. The aim of this study was to determine whether heterozygous AIRE-1 gene mutations are associated with childhood-onset type 1 diabetes and Graves' disease in the Japanese population...

BACKGROUND: Polyglandular auto-immune syndrome type 1 (PAS-1) or auto-immune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED) is a rare autosomal recessive disorder linked to auto-immune regulator (AIRE) gene mutations. Herein, we report the case of a 3-year-old boy with APECED emphasizing the wide phenotypic variability and the extent of skin lesions. PATIENTS AND METHODS: A 3-year-old boy with a history of auto-immune hepatitis was referred for a generalized pruriginous urticaria-like eruption present for one month...

BACKGROUND: Subcutaneous recombinant human parathormone [rhPTH (1-34)] has been introduced for hypoparathyroidism treatment, allowing avoidance of vitamin D and calcium side effects. OBJECTIVE: Our objective was to evaluate rhPTH (1-34) safety and efficacy in pediatric patients with genetically proved syndromic hypoparathyroidism. METHODS: The study was a 2.5-year self-controlled trial on six pediatric patients (four males, two females, age 9...

Autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED) is a rare autosomal recessive disease caused by mutations of the AutoImmune REgulator gene. The clinical spectrum of the disease encompasses several autoimmune endocrine and non-endocrine manifestations, which may lead to acute metabolic alterations and eventually life-threatening events. The clinical diagnosis is defined by the presence of at least two components of the classic triad including chronic mucocoutaneous candidiasis (CMC), chronic hypoparathyroidism (CH), Addison's disease (AD)...

Primary immunodeficiencies (PIDs) represent a large group of diseases that affect all age groups. Although PIDs have been recognized as rare diseases, there is epidemiological evidence suggesting that their real prevalence has been underestimated. We performed an evaluation of a series of 1,008 infants, children, adolescents and adults with well-defined PIDs from a single Brazilian center, regarding age at diagnosis, gender and PID category according to the International Union of Immunological Societies classification...

Autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED) (or autoimmune polyendocrine syndrome type 1) is a rare autosomal recessive disorder caused by mutations in the autoimmune regulator gene. It causes a loss in central immune tolerance, failure to eliminate autoreactive T cells in the thymus, and their escape to the periphery. APECED patients are susceptible to mucocutaneous candidiasis and multiple endocrine and nonendocrine autoimmune diseases. Although it depends on the series, approximately 25% of APECED patients are affected by gastrointestinal (GI) manifestations, mainly autoimmune-related disorders like autoimmune hepatitis, atrophic gastritis with or without pernicious anemia (Biermer disease), intestinal infections, and malabsorption...

Recreational areas cover parks, bicycle paths, lawns, urban squares, sports complexes, holiday camp areas, playgrounds for children, beaches, and even spontaneously used green field open spaces. While using recreational areas, people take with them accompanying animals (dogs, cats). These animals constitute the main source and reservoir of many dangerous zoonoses, including parasitoses caused by roundworms of the genus Toxocara and Trichuris. The objective of the presented study was determination of the level of contamination of soil with parasites' developmental forms (eggs of Toxocara spp...

Autoimmune hepatitis (AIH) is an important entity within the broad spectrum of autoimmune hepatobiliary disease comprised of AIH, primary biliary cirrhosis (PBC) and primary sclerosing cholangitis (PSC). Since the 1960s, AIH has been investigated with extensive clinical research aimed at effective therapeutic intervention. It was one of the first liver diseases where treatment was demonstrated to prolong survival. AIH occurs in children, as well as in adults. Its clinical manifestations in children may differ from classic adult AIH...

INTRODUCTION: autoimmune polyendocrinopathy with candidiasis and ectodermal dystrophy (APECED) is a rare autosomal recessive disorder caused by mutations in the autoimmune regulator gene (AIRE). We report the case of a young girl with APECED. CASE REPORT: an 18 year-old girl born to consanguineous parents consulted for diffuse alopecia. Dermatological examination showed nail and dental enamel dystrophy and angular cheilitis. She had a history of mineralocorticoid deficiency (Addison's disease), hypoparathyroidism, hypogonadism and Biermer's disease, and she had also had chronic mucocutaneous candidiasis since childhood...

The present study was designed to examine the reliability and validity of the Autism Psychodynamic Evaluation of Changes (APEC) scale, developed to assess the evolution in individuals with autism under treatment. The APEC scale focuses on the key role of impairment in body image construction, which requires cross-modal sensory integration through emotional communication with motor representations. Thus, the body image construction is associated simultaneously with spatial and temporal organization and allows the emergence of self- and others-representations...
