We present a case of a 69 year old female with autoimmune polyglandular syndrome type 2 or Schmidt's syndrome. The syndrome consists of primary autoimmune adrenocortical insufficiency (Addison's disease), autoimmune hypothyroidism, and type 1 diabetes. In the presented case Addison's disease was diagnosed on the basis of clinical symptoms, low serum cortisol level: at 8 am 129,1 nmol/l (reference range 220,70-689,70), and high ACTH level: 1540,8 pg/ml (reference range 0-50). Hypothyroidism was diagnosed with serum TSH of 4,46 microU/ml (rr 0,20-3,50), aTPO antibodies titer was 117 U/ml (rr 0-60). The patient also presented insulin dependent diabetes treated with insulin and osteoporosis with a compressive vertebral fracture and a hip fracture in the past (hip T-score = -2,62). After substitutional pharmacotherapy was implemented, the patient was discharged in good health. Possible correlation between bone metabolism disorders and autoimmune polyglandular syndrome needs further investigation.

Autoimmune diseases constitute a heterogeneous group of disorders characterized by the loss of immune tolerance to self-antigens. Despite their distinct clinical picture, there is growing evidence that common molecular mechanisms may contribute to the whole spectrum of autoimmune diseases. This theory is strongly supported by the existence of the autoimmune polyendocrine syndromes (APS). Thus, the clinical diagnosis of APS1 is made in an individual who presents with at least two out of three cardinal symptoms, namely autoimmune Addison's disease, autoimmune hypoparathyroidism, and mucocutaneous candidiasis. APS1 is a rare autosomal recessive syndrome caused by mutations in the autoimmune regulator (AIRE) gene. APS2, which occurs at a much higher frequency, is classically defined as the coexistence of autoimmune Addison's disease, autoimmune thyroid disease, and/or type 1 diabetes. In contrast to APS1, the precise modes of inheritance and the genetic causes underlying APS2 remain unknown. Identification of genetic factors predisposing to this syndrome may contribute to our understanding of common mechanisms involved in autoimmunity.

Autoimmune polyglandular syndromes (APS) consist of the failure of two or more endocrinal glands together requiring hormone replacement. Type II APS, first described by Schmidt in 1926, is the commonest type of APS. In majority of patients, type II APS consists of Addison's disease in combination with autoimmune thyroid disease and type 1 diabetes. We present a case of APS II in a young lady who developed peripartum cardiomyopathy after an uneventful pregnancy.

Autoimmune polyglandular syndrome (APS) type 2 is characterized by the presence of Addison's disease, in association with autoimmune thyroid disease and/or type 1 diabetes mellitus. APS type 2 occurs most often in middle aged females and is rare in children. Here an 11 year old boy is reported with Addison's disease who developed symptom's of diabetes mellitus, goiter, malabsorption, macrocytic anemia and keratitis. APS type 2 occurs most often in middle aged females and is quite rare in children but one should think to autoimmune poly glandular syndrome type II in patient at any age especially in patients with Addison's disease.

Autoimmune polyglandular syndrome (APS) type 2 is defined by the manifestation of at least two autoimmune endocrine diseases. Only few data exist on genetic associations of APS type 2. In this controlled study, 98 patients with APS type 2, 96 patients with type 1 diabetes (T1D), and 92 patients with autoimmune thyroid disease, both as a single autoimmune endocrinopathy, were tested for association with alleles of the human leukocyte antigen (HLA) class II loci DRB1, DQA1, and DQB1. Patients with APS type 2 had significantly more often the alleles DRB1*03 (P(c) < 0.0001), DRB1*04 (P(c) < 0.000005), DQA1*03 (P(c) < 0.0001), and DQB1*02 (P(c) < 0.05), when compared with controls. Less frequent in APS were DRB1*15 (P(c) < 0.05), DQA1*01 (P(c) < 0.0005), and DQB1*05 (P(c) < 0.005). With regard to frequency and linkage of these alleles, the susceptible haplotypes DRB1*0301-DQA1*0501-DQB1*0201 and DRB1*0401/04-DQA1*0301-DQB1*0302 were deduced. Protective haplotypes in this study were DRB1*1501-DQA1*0102-DQB1*0602 and DRB1*0101-DQA1*0101-DQB1*0501. Comparing APS patients with vs without AD, no significant differences regarding HLA class II alleles were noted in our collective. Patients with T1D as a singular disease had the same susceptible and protective HLA alleles and haplotypes. The prevalence of DRB1*03 and DRB1*04 in APS patients was not because of the presence of diabetes, as the APS type 2 patients without diabetes had the same allele distribution. In conclusion, these data suggest a common immunogenetic pathomechanism for T1D and APS type 2, which might be different from the immunogenetic pathomechanism of other autoimmune endocrine disease.

Polyglandular auto-immune syndromes are uncommon constellation of organ specific auto-immune diseases, characterised by the existence of two or more endocrinopathies. Polyglandular autoimmune type II syndrome also known as Schmidt's syndrome is more common, comprising Addison's disease, auto-immune thyroid disease, type 1 diabetes mellitus and/or hypogonadism, pernicious anaemia, coeliac disease, vitiligo, hypophysitis, etc. Here a case of a 56-year-old man is reported with a prior history of hypothyroidism who presented with adrenal crisis. Further laboratory investigations revealed primary auto-immune hypothyroidism, primary adrenal insufficiency, hypogonadism and he was diagnosed as a case of polyglandular auto-immune type II syndrome or Schmidt's syndrome. Early recognition of the syndrome and replacement therapy can be life saving, particularly when there is adrenal or thyroid insufficiency.

Polyglandular autoimmune syndrome is defined as multiple endocrine gland insufficiencies accompanied by autoimmune diseases of the endocrine and nonendocrine system. After Schmidt introduced a case of nontuberculosis adrenal gland dysfunction with thyroiditis in 1926, Neufeld defined polyglandular autoimmune syndrome by I, II, and III subtypes in 1980 by their presentation of occurrence age, heredity methods, relationship with human leukocyte antigen, and accompanying diseases. We report a case of a 32-year-old female with polyglandular autoimmune syndrome III accompanied by type 1 diabetes mellitus that was treated with insulin (36 units per day) for 11 years. She had insulin deficiency and Hashimoto thyroiditis as an autoimmune disorder. In addition, she had several features similar to Albright's hereditary osteodystrophy including short stature, truncal obesity, round face, short neck, low intelligence (full IQ 84), and decreased memory. Although Albright's hereditary osteodystrophy is morphological evidence of pseudohypoparathyroidism or pseudopseudohypoparathyroidism, she had primary hypoparathyroidism on laboratory results. Here, we report a case of polyglandular autoimmune syndrome III with type 1 diabetes mellitus, autoimmune thyroiditis, and primary hypoparathyroidism, accompanied by clinical features similar to Albright's hereditary osteodystrophy.

Schmidt's syndrome or autoimmune polyglandurar syndrome type 2 represents an uncommon endocrine disorder composed by Addison's disease with autoimmune thyroid disease and/or type 1 diabetes mellitus. The syndrome usually affects women in the fourth decade of their lives. Prompt diagnosis and treatment can prevent serious complications. We present the case of a 64-year-old woman with generalised anxiety, facing socio-economic problems. Her symptoms attributed to stress led to a late diagnosis. Physicians involved have to be aware about endocrine disorders of which first manifestations may have atypical components mimicking mental health problems.

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.

Achalasia is a rare disease characterized by aperistalsis of the esophageal body and failure of the lower esophageal sphincter to relax. The etiology of this disease remains unknown. Polyglandular autoimmune syndrome type II is a well-identified disease characterized by the occurrence of autoimmune Addison's disease in combination with autoimmune thyroid disease and/or type 1 diabetes mellitus. We report a case that suggests autoimmunity and immunogenicity as a probable contributing factor for association of these two rare disorders.
