Autoimmune Polyglandular Syndrome (APS) Type 1 is a rare hereditary disorder that damages organs in the body. This disease entity is the result of a mutation in the AIRE gene. It is characterized by three classic clinical features - hypoparathyroidism, Addison's disease, and chronic mucocutaneous candidiasis. For a patient to be diagnosed as having APS Type 1 syndrome at least two of these features needs to be present. The third entity may develop as the disease progresses. We report a case of a 35-year-old female patient with a history of seizure from the age of 11 years, who was managed with anticonvulsant drugs. With worsening of the seizure episodes, patient was diagnosed to have hypoparathyroidism together with the manifestations of oral candidiasis, nails dystrophy, enamel hypoplasia, and hypogonadism. A diagnosis of APS-1 was considered. The facility for genetic analysis of the AIRE gene mutation was not accessible, as the test costs were prohibitive and not affordable for the patient. Patient management was directed to treating individual disease components. However, cerebral and dental changes were irreversible.

Autoimmune polyendocrinopathy syndrome type 1 (APS-1) is characterized by the presence of at least two out of three clinical features, which include chronic mucocutaneous candidiasis (CMC), Addison's disease and hypoparathyroidism. The authors' present an one and a half year old girl with recurrent oral thrush who presented with generalised afebrile seizure. Evaluation revealed severe hypocalcemia with low parathormone and normal vitamin D level consistent with hypoparathyroidism. In view of the oral candidiasis and hypoparathyroidism, a clinical possibility of autoimmune polyglandular syndrome (type 1) was strongly considered. Her mother, on subsequent pregnancy was subjected to gene analysis of the fetus (chorionic villus sampling) and also for this child (index case). Both the fetus and index child were confirmed to have the AIRE gene mutation of APS1. After detailed counseling the parents opted for medical termination of the pregnancy. In children who present with recurrent oral thrush we need to consider but also look beyond immunodeficiency.

Hypocalcaemia is an established cause of neurological and psychiatric disease with numerous clinical manifestations. The aim of the study was to determine the outcome of severe neuropsychiatric manifestations of chronic hypocalcaemia after correction of calcium levels. Clinical and laboratory data of 22 patients seen between 1999 and 2009 were retrospectively analysed. Calcium, magnesium, phosphorus, albumin and parathormone values were measured in all cases. All patients except infants under one year of age had computed tomography (CT) scans of the head. Most patients (n = 19; 86%) presented with generalised tonic clonic convulsions while three had seizures with psychiatric manifestations. Movement disorders were present in 4 patients and one had candida meningitis. Nineteen of the 22 patients had primary hypoparathyroidism of which one had associated mucocutaneous candidiasis. One had pseudohypoparathyroidism and two had vitamin D deficiency. All patients improved with calcitriol and calcium treatment. Twelve of the 14 patients with convulsions could be taken off anticonvulsants. Hemiballismus disappeared in one patient and choreiform movements disappeared in one patient and dystonia in two patients. Psychiatric manifestations improved but did not disappear in the three patients who had them. Adult patients with seizures or neuropsychiatric manifestations should have calcium levels checked. Seizure disorders due to chronic hypocalcaemia had excellent prognosis on correction of serum calcium levels. Movement disorders improved markedly. Psychiatric manifestations did not improve substantially on correction of serum calcium levels.

Autoimmune polyglandular syndrome type 2 (type 2 APS), or Schmidt's syndrome, is defined by the presence of Addison's disease in combination with type 1 diabetes and/or autoimmune thyroid disease. The estimated prevalence of this syndrome is 1.4-4.5 per 100,000 inhabitants and it is more frequent in middle-aged females, whilst it is quite rare in children. Type 2 APS, which shows a pattern of autosomal dominant inheritance with low penetrance, has been associated with HLA specific DR3/DQ2 and DR4/DQ8 haplotypes. However, it has been hypothesized that genetic variability in the AIRE gene, which causing type 1 APS, may play a role in more common organ-specific autoimmune conditions like type 1 diabetes, Hashimoto's disease and type 2 APS, among others. Here we present the case of an 8-year-old girl, with a past medical history of type 1 diabetes diagnosed at the age of 3. She was taken to the Emergency Department because she complained of abdominal pain, nausea and vomiting, and her blood analysis revealed a severe hyponatremia. She also had seizures as a consequence of the hyponatremia and frequent hypoglycemia. She was ultimately found to be suffering from autoimmune primary adrenal insufficiency. The combination of both mentioned conditions, type 1 diabetes and Addison's disease, in the absence of chronic mucocutaneous candidiasis, made a diagnosis of type 2 APS plausible in this girl. The genetic study showed two heterozygous variants: NM_000383.2:C.1411C>T (p. Arg471Cys) in exon 12 and IVS9+6G>A in intron 9 of the AIRE gene. The description of an uncommon case of type 2 APS with precocious presentation associated with an AIRE mutation in a very young girl could help to clarify the role of AIRE in the development of autoimmune diseases.

Biotinidase deficiency (BD) is an inborn metabolic disorder inherited in an autosomal recessive manner. Partially due to high consanguinity rates in Turkey, BD incidence is high in Turkey. If left untreated, neurological abnormalities including seizures, hypotonia, sensorineural deafness, alopecia, egzamatous skin rash and candidiasis may occur. Three-years-old girl was admitted to hospital with recurrent infections, candidiasis and egzamatous skin rash. Immunological evaluation was normal. Associated deafness and consanguinity of the parents suggested BD which has been proven by enzyme activity measurement. With this report, we want to emphasise that BD can be the underlying cause of recurrent infections and candidiasis.

The autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED) syndrome is a genetic disorder caused by a mutation in the autoimmune regulator (AIRE) gene. Immune deficiency, hypoparathyroidism and Addison's disease due to autoimmune dysfunction are the major clinical signs of APECED. We report on a 21-year-old female APECED patient with two inactivating mutations in the AIRE gene. She presented with sudden onset of periodic nausea. Adrenal insufficiency was diagnosed by means of the ACTH stimulation test. Despite initiation of hormone replacement therapy with hydrocortisone and fludrocortisone, nausea persisted and the patient developed cognitive deficits and a loss of interest which led to the diagnosis of depression. She was admitted to the psychiatric department for further diagnostic assessment. An EEG showed a focal epileptic pattern. Glutamic acid decarboxylase (GAD) antibodies, which had been negative eight years earlier, were now elevated in serum and in the cerebrospinal fluid. Oligoclonal bands were positive indicating an inflammatory process with intrathecal antibody production in the central nervous system (CNS). The periodic nausea was identified as dialeptic seizures, which clinically presented as gastrointestinal aura followed by episodes of reduced consciousness that occurred about 3-4 times per day. GAD antibody-associated limbic encephalitis (LE) was diagnosed. Besides antiepileptic therapy, an immunosuppressive treatment with corticosteroids was initiated followed by azathioprine. The presence of nausea and vomiting in endocrine patients with autoimmune disorders is indicative of adrenal insufficiency. However, our case report shows that episodic nausea may be a symptom of epileptic seizures due to GAD antibodies-associated LE in patients with APECED.
