Autoimmune thyropathies are frequent in patients with type 1 diabetes mellitus. Some recently published papers confirm similarly high prevalence of autoimmune thyropathies also in patients with type 2 diabetes mellitus. Chronic autoimmune thyroiditis is the most frequent form of autoimmune thyropathies. Authors examined 79 accidentally selected diabetics (38 women and 41 men, x = 55.4 +/- 2.8). Diabetic patients were divided into three groups. 20 patients with type 1 diabetes mellitus - classical form were the first group, 12 patients with LADA were the second group and 47 patients with type 2 diabetes mellitus constituted the third group. Authors diagnosed chronic autoimmune thyroiditis in 8 (40 %) patients in the group of patients with type 1 diabetes mellitus, in 6 (50%) in the group of patients with LADA and in 20 (43%) of patients with type 2 diabetes mellitus. They didn't find out statistically more frequent prevalence of chronic autoimmune thyroiditis in all groups of patients with diabetes (patients with type 1 diabetes mellitus, patients with LADA, patients with type 2 diabetes mellitus) in comparison with control group of non-diabetic subjects. They found out statistically significant more frequent prevalence of chronic autoimmune thyroiditis in diabetics of woman gender and in diabetics with positive family history of thyropathies. Results of paper confirm recommendation of examining once or twice a year autoantibodies against thyroid gland and level of thyrotropin (TSH) with the aim of early finding of laboratory manifestation of thyroidal autoimmunity or developing functional disorder.

Vitiligo is a common skin disease characterized by depigmented maculae resulting from a reduction of the number and function of melanocytes. Many studies suggest that vitiligo might be an autoimmune disease. Vitiligo has been frequently described in association with other autoimmune diseases. Among the diseases described in association with vitiligo are the so-called autoimmune polyglandular syndromes (APS). Vitiligo can be present in all types of APS but the most frequent association appears to be in APS-3. APS-3 was defined as the association between autoimmune thyroiditis and another autoimmune disease. Here we report one patient with thyroiditis, vitiligo and autoimmune gastritis (APS-3B+C), one patient with chronic autoimmune thyroiditis, vitiligo and alopecia (APS-3C), and one case of a young patient with type 1 diabetes mellitus and vitiligo (APS-4), according to the newest classification. We stress the importance of a thorough assessment for autoimmune diseases in selected patients with vitiligo.

Chemokines are a group of peptides of low molecular weight that induce the chemotaxis of different leukocyte subtypes. The major function of chemokines is the recruitment of leukocytes to inflammation sites, but they also play a role in tumoral growth, angiogenesis, and organ sclerosis. In the last few years, experimental evidence accumulated supporting the concept that interferon-gamma (IFN-gamma) inducible chemokines (CXCL9, CXCL10, and CXCL11) and their receptor, CXCR3, play an important role in the initial stage of autoimmune disorders involving endocrine glands. The fact that, after IFN-gamma stimulation, endocrine epithelial cells secrete CXCL10, which in turn recruits type 1 T helper lymphocytes expressing CXCR3 and secreting IFN-gamma, thus perpetuating autoimmune inflammation, strongly supports the concept that chemokines play an important role in endocrine autoimmunity. This article reviews the recent literature including basic science, animal models, and clinical studies, regarding the role of these chemokines in autoimmune endocrine diseases. The potential clinical applications of assaying the serum levels of CXCL10 and the value of such measurements are reviewed. Clinical studies addressing the issue of a role for serum CXCL10 measurement in Graves' disease, Graves' ophthalmopathy, chronic autoimmune thyroiditis, type 1 diabetes mellitus, and Addison's disease have been considered. The principal aim was to propose that chemokines, and in particular CXCL10, should no longer be considered as belonging exclusively to basic science, but rather should be used for providing new insights in the clinical management of patients with endocrine autoimmune diseases.

We report a patient with combined polycystic ovary syndrome (PCOS) and autoimmune polyglandular syndrome (APS) type 2. A 26-year-old female presented with polyuria, polydipsia and acute weight loss. She was diagnosed with: (1) type 1 diabetes, with hyperglycemia, impaired insulin secretion, and positive autoantibodies for GAD-65 and IA-2; (2) autoimmune thyroiditis, with hypothyroidism, positive anti-microsomal and antithyroglobulin antibodies; and (3) PCOS, with hyperandrogenic signs that had developed 5 years earlier, amenorrhea for the previous 6 months, and characteristic multiple microcystic appearance of both ovaries on ultrasonography. She is being treated with multiple subcutaneous insulin injections, thyroxine replacement, and cyclic medroxyprogesterone for the aforementioned diseases, respectively. Although several investigations have reported a relationship between PCOS and the individual components of APS, this is the first report of both syndromes occurring simultaneously. Potential mechanisms for their interrelation and the possibility that PCOS is an autoimmune disease are discussed.

Autoimmune diseases are caused by a defect of the human immune system characterised by an inability to recognize their own antigens and by a pathological response against these antigens. Although the aetiology of these diseases is unknown, there is a number of cellular and molecular mechanisms which can underlie these reactions. Complex interactions between genetic, infectious and/or environmental factors probably contribute to the presence of these diseases. Autoimmune diseases affect 3-8% of the general population; women account for 78-85% of all patients with autoimmune diseases. Although most of those diseases are systemic, some of them primarily affect a single organ or structure. Rarely, a few autoimmune diseases coexist in one person, which can suggest similar pathogenetic mechanisms. In this article we present a review of the literature on coexistence of multiple sclerosis and other autoimmune diseases such as systemic lupus erythematosus, rheumatoid arthritis, chronic active hepatitis, type 1 diabetes mellitus, uveitis, pemphigus, psoriasis, Crohn's disease, inflammatory bowel disease, anaemia and autoimmune thyroiditis.

Celiac disease (CD) is one of the most common chronic disorders in childhood. Autoimmune and nonautoimmune disorders including dermatitis herpetiformis, type 1 diabetes mellitus, and autoimmune thyroiditis can be encountered associated with CD. Common hematologic manifestations of CD include anemia owing to iron, folate, or vitamin B12 deficiency. We report a case with CD associated with Evans syndrome of whom to our knowledge, is the first child to be reported in the literature.

Celiac disease (CD) is a life-long inflammatory autoimmune condition of the gastrointestinal tract affecting genetically susceptible individuals. Several autoimmune disorders are more prevalent in patients and their close relatives and that risk is gluten exposure duration related. The most frequent reported CD associated conditions are type 1 diabetes mellitus and autoimmune thyroiditis. Associated autoimmune antibodies are frequent in CD and their first-degree relatives, spanning anti-endocrine, anti-gastrointestinal, anti-nuclear, anti-cytoskeleton and anti-neurological antibodies. More specifically, antibodies against thyroid and the endocrine pancreas, anti-gastric and liver, anti-nuclear constituents, anti-reticulin, actin, smooth muscle, calreticulin, desmin, collagens and bone, anti-brain, ganglioside, neuronal and blood vessel were described in sera of the patients in numerous studies. The common immunogenetic theories for the above associations are: sharing common HLA and non-HLA genes, antigenic mimicry, damage-induced neoantigen exposure, altered intestinal permeability, idiotype network dysregulation and epitope spreading. The CD associated autoantibodies enigma, being an epiphenomenon or pathogenic, remains unresolved and presents a challenging area for future research.

Celiac disease is an autoimmune disorder caused by the continued ingestion of gluten, a protein found in wheat, barley and rye, by predisposed individuals. With the development of highly sensitive serologic tests, this has become an increasingly recognized disease with prevalence as high as 1% in certain patient populations, such as Caucasian females. Almost all celiac patients carry the human leukocyte antigen DQ2/DQ8 gene. Much has recently been discovered about the role of the innate immune system in exposing genetically vulnerable patients to the pathogenic gliadin fraction of gluten. The "classical" presentation of chronic diarrhea and malabsorption is now a rarity. Due to earlier detection and increased awareness, celiac disease now presents with a myriad of "atypical" signs and symptoms such as iron-deficiency anemia and osteoporosis. Associated conditions include T-cell lymphoma, dermatitis herpetiformis, autoimmune thyroiditis and type 1 diabetes. Diagnosis requires serologic confirmation with either antiendomysial or antitransglutaminase antibodies as well as histologic confirmation from endoscopic small bowel biopsy. The only effective treatment necessitates a lifelong, continual adherence to a gluten-free diet.

Patients with an autoimmune condition are known to be at higher risk of developing other autoimmune disorders. Type 1 diabetes may be associated with additional autoimmune disorders including autoimmune thyroid disease. The aim of this study was to investigate the prevalence of thyroid autoantibodies in a group of children, adolescents, and young adults with type 1 diabetes from northeastern Brazil as well as their significance for the development of thyroid disorders. The study design was cross-sectional and descriptive, analyzing young people with a previous type 1 diabetes diagnosis. Two hundred and fourteen children and adolescents with prior diagnosis of type 1 diabetes were evaluated. Antibodies to thyroperoxidase (anti-TPO) were determined in all patients and thyroid-stimulating hormone (TSH) levels. The anti-TPO antibody test was positive in 54 out of the 214 patients studied, resulting in an overall prevalence of 25.2%. Among the anti-TPO-positive subjects, females were predominant (72%) over males (28%) (p < 0.001). A total of 55.5% patients with positive anti-TPO antibodies had abnormal TSH levels. Clinically significant hypothyroidism was found in 29.6% and subclinical hypothyroidism in 22.2% of patients with positive anti-TPO. Hyperthyroidism was present in only 3% of them. Our results demonstrate the high prevalence of autoimmune thyroiditis in patients with type 1 diabetes and the need for these patients of regular screening to make a precocious diagnosis of thyroid dysfunction.

The objective of the study was to investigate whether immunologic and biochemical events occurring in the course of type 1 diabetes mellitus might play a role in the development of the celiac disease. The study was carried out on 223 children with long-standing diabetes mellitus type 1 (DM1). All the patients had TSH, fT4, fT3, urinary albumin secretion rate, IgA, level of antigliadin antibodies (AGA) IgA and IgG, antitissue transglutaminase IgA antibodies, antiendomysium (EmA) IgA and IgG antibodies and antitireoglobulin antibodies, antithyroid peroxidase antibodies evaluated. Serum TNF-alpha, IL-6, and IL-10 levels were also measured. The group of children with coincident DM1 and celiac disease and without autoimmune thyroiditis was characterized by significantly higher glycosylated hemoglobin, higher serum TNF-alpha, IL-6 but lower serum IL-10 in relation to the remaining diabetic patients. A statistically significant positive correlation was observed between IgA-anti-tTG and serum TNF-alpha (R = 0.28, p = 0.026); between IgG AGA and serum IL-6 (R = 0.31, p = 0.023); and between glycosylated hemoglobin and IgA-anti-tTG (R = 0.21, p = 0.001) and IgA antiendomysium (R = 0.22, p = 0.001). Poor metabolic control, persistent elevated levels of proinflammatory cytokines, and decreased level of antiinflammatory cytokines occurring in the course of type 1 diabetes mellitus might influence the incidence of celiac disease.
