Abstract
Vitamin D is a secosteroid hormone that is highly involved in bone health. Mounting evidence revealed that, in addition to the regulation of mineral metabolism, vitamin D is implicated in cell proliferation and differentiation, vascular and muscular functions, and metabolic health. Since the discovery of vitamin D receptors in T cells, local production of active vitamin D was demonstrated in most immune cells, addressing the interest in the clinical implications of vitamin D status in immune surveillance against infections and autoimmune/inflammatory diseases. T cells, together with B cells, are seen as the main immune cells involved in autoimmune diseases; however, growing interest is currently focused on immune cells of the innate compartment, such as monocytes, macrophages, dendritic cells, and natural killer cells in the initiation phases of autoimmunity. Here we reviewed recent advances in the onset and regulation of Graves' and Hashimoto's thyroiditis, vitiligo, and multiple sclerosis in relation to the role of innate immune cells and their crosstalk with vitamin D and acquired immune cells.

Abstract
Vitiligo is a common depigmentation disorder of an unknown origin characterized by the selective loss of melanocytes, resulting in typical white macules and patches. However, vitiligo is now recognized as more than just a skin disease, what a dermatologist observes as a white spot of skin is just the "tip of the iceberg" of the condition. We attempt to clarify the classification of comorbidities associated with vitiligo from various reviews and reports, and describe their possible pathogenesis. In conclusion, the literature provides evidence of an association between vitiligo and ocular and auditory abnormalities, autoimmune disorders, other dermatological diseases, metabolic syndrome and related disorders, and psychological diseases. These associations highlight the importance of a multidisciplinary approach in managing vitiligo patients.

Abstract
Alopecia areata (AA) is an organ-specific autoimmune disease which affects hair follicles. It usually presents as a transient patchy hair loss, but it can sometimes progress into more severe forms such as AA totalis or AA universalis (AAU). Different autoimmune diseases, as well as autoimmune polyglandular syndromes (APS), have been associated with AA, especially with Type I and Type II APS. Herein, we describe the case of a 16-year-old boy with a severe form of AAU and early onset of adult APS, Type III C. As far as we are aware, this combination of AAU, Hashimoto thyroiditis, and Type I diabetes in a teenager has not been previously described in the literature. Furthermore, the early onset of AAU followed by a premature debut of adult APS Type III is again unique, which is why we report this case.

Abstract
Autoimmune polyendocrine syndrome (APS) is assumed to involve an immune system malfunction and entails several autoimmune diseases co-occurring in different tissues of the same patient; however, they are orphans of its accurate diagnosis, as its genetic basis and pathogenic mechanism are not understood. Our previous studies uncovered alterations in the ATPase H+/K+ Transporting Subunit Alpha (ATP4A) proton pump that triggered an internal cell acid-base imbalance, offering an autoimmune scenario for atrophic gastritis and gastric neuroendocrine tumors with secondary autoimmune pathologies. Here, we propose the genetic exploration of APS involving gastric disease to understand the underlying pathogenic mechanism of the polyautoimmune scenario. The whole exome sequencing (WES) study of five autoimmune thyrogastric families uncovered different pathogenic variants in SLC4A2, SLC26A7 and SLC26A9, which cotransport together with ATP4A. Exploratory in vitro studies suggested that the uncovered genes were involved in a pathogenic mechanism based on the alteration of the acid-base balance. Thus, we built a custom gene panel with 12 genes based on the suggested mechanism to evaluate a new series of 69 APS patients. In total, 64 filtered putatively damaging variants in the 12 genes of the panel were found in 54.17% of the studied patients and none of the healthy controls. Our studies reveal a constellation of solute carriers that co-express in the tissues affected with different autoimmune diseases, proposing a unique genetic origin for co-occurring pathologies. These results settle a new-fangled genetics-based mechanism for polyautoimmunity that explains not only gastric disease, but also thyrogastric pathology and disease co-occurrence in APS that are different from clinical incidental findings. This opens a new window leading to the prediction and diagnosis of co-occurring autoimmune diseases and clinical management of patients.

Abstract
BACKGROUND AND AIM Autoimmune atrophic gastritis (AAG) is characterized by a variable spectrum of gastric and extra-gastric symptoms and has been associated with other autoimmune diseases. It is still unknown whether AAG patients have a higher risk of coeliac disease (CeD) or of any other particular duodenal histological damage. Our study aimed at evaluating the duodenal histological findings and the risk of CeD in patients with AAG, with and without other concurrent autoimmune diseases. METHODS We retrospectively collected all the histological findings of the adult patients undergoing upper gastrointestinal endoscopy with concurrent duodenal and gastric biopsies at our gastroenterology unit between 2015 and 2018 and who were regularly followed up at our centre. Date of endoscopy evaluation, endoscopy indication, data on previous CeD diagnosis and on other autoimmune-associated diseases, and a description of histological diagnosis were recorded. RESULTS Of the 2,423 evaluated endoscopies, 209 patients had an AAG diagnosis (8.6%). One hundred thirty-nine patients, aged 57.4 (standard deviation 13.2) years, were regularly followed up at our centre and were included. Of them, 4 subjects had a previous diagnosis of CeD and one had CeD diagnosis at index endoscopy. Additionally, 8 patients had an isolated increase of intraepithelial lymphocytes (IELs, 6%) and 2 villous atrophy with a normal IEL count. The risk of CeD in AAG was not modulated by the presence of other concurrent autoimmune diseases. CONCLUSIONS We support the screening of all AAG patients with CeD autoantibodies. Findings of isolated IEL or villous atrophy are not exclusively related to CeD.

Abstract
Vitiligo is a common polygenic autoimmune disease in which the foci of depigmentation are formed on the skin and/or mucous membranes as a result of the death of melanocytes. There are several hypotheses for the pathogenesis of the disease, the leading role among them is played the autoimmune hypothesis. This review summarizes the available literature data on the prevalence and structure of comorbid endocrine autoimmune pathology in vitiligo patients. In most studies conducted in Europe, America and Asia the prevalence of autoimmune thyroid diseases (including autoimmune thyroiditis and Graves disease), diabetes mellitus and autoimmune adrenal insufficiency was higher in vitiligo patients than in the general population. The results of some studies indicate a frequent association of vitiligo with autoimmune polyglandular syndromes. In the structure of comorbid pathology the highest prevalence was in autoimmune thyroid diseases. A number of studies have established a higher prevalence of autoimmune endocrine diseases in women, as well as in nonsegmental vitiligo patients and in cases of family history of vitiligo and/or other autoimmune diseases. In addition, it was shown that the prevalence of endocrine diseases increases with increasing area of depigmentation. The data obtained justify the advisability of conducting a timely examination of vitiligo patients with the aim of early detection of comorbid diseases and the appointment of appropriate treatment. Further studies are needed to investigate the effect of the identified associations on the course of vitiligo and comorbid endocrinopathies, as well as the effectiveness of therapy and the quality of life of patients.

Abstract
Autoimmune metaplastic atrophic gastritis (AMAG) previously called type A chronic gastritis is an immune-mediated chronic inflammatory disease characterized by the immune-mediated destruction of gastric parietal cells in the fundus and body of the stomach. AMAG is an uncommon disease that often presents with hematological manifestations and may lead to the development of gastric carcinoids. AMAG can be reliably diagnosed by antibody assays, functional serology, and histology. The understanding of the disease process is essential for the detection and management of hematological complications and gastric lesions. The prevalence of AMAG is on the rise and subsequently gastric carcinoids. However, this association is not well recognized in clinical practice, and management and diagnosis of AMAG and gastric carcinoids remain suboptimal. In the current review, we will discuss the pathophysiology, diagnosis and management of AMAG. A special focus is given to the association between AMAG and gastric carcinoids. We will also review the management options of type 1 gastric carcinoids.

Abstract
BACKGROUND Hashimoto thyroiditis (HT) is uncommon in infancy, and myxedema coma (MC) is even less common. While prior reports have documented these entities separately, to our knowledge, MC in combination with HT has not been reported before in this age group. METHODS/RESULTS A 10-month-old female presented with ptosis, lethargy, dysphagia, and failure to thrive (FTT). She developed hypotension, bradycardia, hypothermia, and apnea requiring intubation. Initial thyroid-stimulating hormone was 422 μIU/mL, and free thyroxine was < 0.5 ng/dL, despite the presence of a normal thyroid newborn screen (NBS). Of note, sepsis workup was unremarkable. With the diagnosis of MC, treatment with intravenous levothyroxine was initiated, although after hydrocortisone administration to avert the possibility of an adrenal crisis, despite a random cortisol of 16.4 μg/dL. Based on positive thyroid antibodies suggesting HT, autoimmune workup later revealed positive acetylcholinesterase antibodies consistent with a diagnosis of ocular myasthenia gravis. CONCLUSION MC may be a cause of altered mental status in infancy and may simultaneously be associated with FTT on presentation. With the presence of a normal thyroid NBS, autoimmunity should be entertained as the etiology of profound hypothyroidism, as positive thyroid antibodies may prompt an exploration for coexisting diseases which may explain other presenting features.

Abstract
BACKGROUND Chronic atrophic autoimmune gastritis (CAAG) leads to vitamin B12 deficiency, but other micronutrient deficiencies are largely understudied. AIMS To investigate the prevalence of micronutrient deficiencies in CAAG patients and their potential relationship with the grading of gastric atrophy or entero-chromaffin-like cells hyperplasia or body mass index (BMI). METHODS From 2005 to 2016 a number of CAAG patients underwent regular follow-up with annual blood testing and upper gastrointestinal tract endoscopy every years. RESULTS Out of the 122 CAAG patients checked (100 F; median age 65 years), 76 presented nutritional deficiencies, single in 24 and multiple in 52 cases: a deficiency of B12 and iron showed in 42 patients, 25-OH vitamin D lacked in 76 and folic acid in 6 cases. 25-OH vitamin D levels directly correlated with B12 levels and were significantly lower in patients with macronodular than in those with linear or micronodular hyperplasia. No significant correlation was observed between B12, folic acid or ferritin levels and BMI, blood gastrin levels, the grading of gastric atrophy or ECL cells hyperplasia. CONCLUSIONS 25-OH vitamin D deficiency was the main one in CAAG patients: its correlation with B12 deficiency may indicate underlying shared pathogenic mechanisms, although further studies are needed to confirm this hypothesis.

Abstract
Autoimmune disorders derive from genetic, stochastic, and environmental factors that all together interact in genetically predisposed individuals. The impact of an imbalanced gut microbiome in the pathogenesis of autoimmunity has been suggested by an increasing amount of experimental evidence, both in animal models and humans. Several physiological mechanisms, including the establishment of immune homeostasis, are influenced by commensal microbiota in the gut. An altered microbiota composition produces effects in the gut immune system, including defective tolerance to food antigens, intestinal inflammation, and enhanced gut permeability. In particular, early findings reported differences in the intestinal microbiome of subjects affected by several autoimmune conditions, including prediabetes or overt disease compared to healthy individuals. The present review focuses on microbiota-host homeostasis, its alterations, factors that influence its composition, and putative involvement in the development of autoimmune disorders. In the light of the existing literature, future studies are necessary to clarify the role played by microbiota modifications in the processes that cause enhanced gut permeability and molecular mechanisms responsible for autoimmunity onset.

Abstract
Autoimmune diseases, characterized by an alteration of the immune system which results in a loss of tolerance to self antigens often coexist in the same patient. Autoimmune atrophic gastritis, characterized by the development of antibodies agains parietal cells and against intrinsic factor, leads to mucosal destruction that affects primarily the corpus and fundus of the stomach. Autoimmune atrophic gastritis is frequently found in association with thyroid disease, including Hashimoto's thyroiditis, and with type 1 diabetes mellitus, Other autoimmune conditions that have been described in association with autoimmune atrophic gastritis are Addison's disease, chronic spontaneous urticaria, myasthenia gravis, vitiligo, and perioral cutaneous autoimmune conditions, especially erosive oral lichen planus. Interestingly, however, celiac disease, another frequent autoimmune condition, seems to play a protective role for autoimmune atrophic gastritis. The elevated prevalence of autoimmune disease clustering should prompt the clinicial to exclude concomitant autoimmune conditions upon diagnosis of any autoimmune disease.

Abstract
Polyglandular autoimmune syndrome (PAS) type 3 consists of autoimmune thyroid disease (AITD) coexisting with ≥1 non-thyroidal autoimmune disease (NTAID) other than Addison's disease and hypoparathyroidism. We evaluated the prevalence and repertoire of thyroid hormones antibodies (THAb) in PAS-3 patients. Using a radioimmunoprecipation technique, we measured THAb (T3IgM, T3IgG, T4IgM, and T4IgG) in 107 PAS-3 patients and 88 controls (patients with AITD without any NTAID). Based on the selective coexistence of AITD with one NTAID (chronic autoimmune gastritis, non-segmental vitiligo or celiac disease), patients were divided into group 1 (chronic autoimmune gastritis positive, n = 64), group 2 (non-segmental vitiligo positive, n = 24), and group 3 (celiac disease positive, n = 15). At least one of the four THAb was detected in 45 PAS-3 patients (42.1%) and 28 controls (31.8%, P = 0.14), with similar rates in the three PAS-3 groups. The rates of T3Ab, T4Ab, and T3 + T4Ab were similar in groups 1 and 2, while in group 3, T3Ab was undetected (P = 0.02). In PAS-3 patients, the rate of levothyroxine treatment was greater in THAb-positive patients compared to THAb-negative patients (76.7 vs. 56.1%, P = 0.03, RR = 1.4, 95% CI 1.03-1.81). Not unexpectedly, levothyroxine daily dose was significantly higher in group 1 and group 3, namely in patients with gastrointestinal disorders, compared to group 2 (1.9 ± 0.4 and 1.8 ± 0.3 vs. 1.5 ± 0.2 μg/kg body weight, P = 0.0005 and P = 0.004). Almost half of PAS-3 patients have THAb, whose repertoire is similar if chronic autoimmune gastritis or celiac disease is present. A prospective study would confirm whether THAb positivity predicts greater likelihood of requiring levothyroxine treatment.

Abstract
At present there is no universally accepted classification for gastritis. The first successful classification (The Sydney System) that is still commonly used by medical professionals was first introduced by Misiewicz et al in Sydney in 1990. In fact, it was the first detailed classification after the discovery of Helicobacter pylori by Warren and Marshall in 1982. In 1994, the Updated Sydney System was proposed during the International Workshop on the Histopathology of Gastritis followed by the publication in The American Journal of Surgical Pathology by Dixon et al. Using the new classification, distinction between atrophic and nonatrophic gastritis was revised, and the visual scale grading was incorporated. According to the Updated Sydney System Classification, atrophic gastritis is categorized into multifocal (H. pylori, environmental factors, specific diet) and corpus-predominant (autoimmune). Since metaplasia is a key histological characteristic in patients with atrophic gastritis, it has been recommended to use the word “metaplastic” in both variants of atrophic gastritis: autoimmune metaplastic atrophic gastritis (AMAG) and environmental metaplastic atrophic gastritis. Although there are many overlaps in the course of the disease and distinction between those two entities may be challenging, the aim of this review article was to describe the etiology, epidemiology, pathogenesis, diagnosis, clinical manifestations and treatment in patients with AMAG. However, it is important to mention that H. pylori is the most common etiologic factor for the development of gastritis in the world.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Vitiligo is a depigmentation disorder, which results in substantial cosmetic disfigurement and poses a detriment to patients' physical as well as mental. Now the molecular pathogenesis of vitiligo still remains unclear, which leads to a daunting challenge for vitiligo therapy in modern medicine. Herbal medicines, characterized by multi-compound and multi-target, have long been shown effective in treating vitiligo, but their molecular mechanisms of action also remain ambiguous. MATERIALS AND METHODS Here we proposed a systems pharmacology approach using a clinically effective herb formula as a tool to detect the molecular pathogenesis of vitiligo. This study provided an integrative analysis of active chemicals, drug targets and interacting pathways of the Uygur medicine Qubaibabuqi formula for curing Vitiligo. RESULTS The results show that 56 active ingredients of Qubaibabuqi interacting with 83 therapeutic proteins were identified. And Qubaibabuqi probably participate in immunomodulation, neuromodulation and keratinocytes apoptosis inhibition in treatment of vitiligo by a synergistic/cooperative way. CONCLUSIONS The drug-target network-based analysis and pathway-based analysis can provide a new approach for understanding the pathogenesis of vitiligo and uncovering the molecular mechanisms of Qubaibabuqi, which will also facilitate the application of traditional Chinese herbs in modern medicine.

Abstract
Diabetes mellitus is one of the most common diseases in the Western industrialized countries with about 300 million affected patients worldwide. The hyperglycemic state of diabetes mellitus leads to changes in practically every cell type and organ of the human body. Skin changes are considered the most common manifestations of diabetes mellitus. As skin changes can manifest before onset of diabetes mellitus they may have a diagnostic relevance. Other changes and diseases of the skin develop during the course of diabetes mellitus and may be associated with complications in internal organs or may occur as an adverse effect of antidiabetic therapy. In particular the presence of the diabetic foot syndrome is associated with significantly increased morbidity and mortality of diabetes patients as well as with markedly elevated direct and indirect costs for the health care system. In this article the most common skin diseases of patients with diabetes mellitus as well as their pathophysiology and current treatment are reviewed.

Abstract
Vitiligo in association with autoimmune endocrine disorders, especially with hypothyroidism, is not uncommon. Some amount of pericardial effusion is usually present in long-standing/untreated hypothyroidism. Here we describe the case of young male with, long-standing progressive vitiligo, presenting with congestive cardiac failure due to dilated cardiomyopathy and primary hypothyroidism. Cardiac dysfunction progressively improved with thyroid hormone replacement over a period of 2 years.

Abstract
Chronic lymphocytic thyroiditis and vitiligo often occur in association and seem to be characterized by a prevalent Th1-driven autoimmune process. The aim of this study is to analyze selected intracellular Τh1 and Th2 cytokines in patients with Hashimoto?s thyroiditis when associated with non-segmental vitiligo. We analyzed intracellular interleukin-2, interferon-gamma (Τh1) and interleukin-4 (Th2), in peripheral blood lymphocytes of 23 patients with isolated Hashimoto?s thyroiditis (group A) and of 11 patients with Hashimoto?s thyroiditis associated with non-segmental vitiligo (group B). Peripheral blood lymphocytes were stimulated and incubated with specific monoclonal antibodies. Intracellular cytokines were assayed by flow cytometric analysis. Interleukin-2 and interferon-gamma positive cells were increased in almost all patients but the median values were similar in patients with isolated Hashimoto?s thyroiditis and in those with concurrent vitiligo. In contrast, the number of patients with increased interleukin-4 positive cells was higher in patients with thyroiditis and vitiligo (9/11) than in those with isolated thyroiditis (2/23; p<0.0001). The median values of IL-4 positive cells in the two groups confirmed this difference (A: 5.8 percent, vs B: 20.6 percent; p=0.0011). Increased interleukin-4 positive lymphocytes characterize Hashimoto?s thyroiditis when associated with non-segmental vitiligo, suggesting a modified balance from highly prevalent Th1 to mixed Th1/Th2 subset.

Abstract
The clinical and instrumental findings revealed a case of autoimmune polyendocrine syndrome (APS) type 3B+C in a 41-year-old Caucasian woman with unexplained refractory iron-deficiency anaemia secondary to autoimmune atrophic gastritis and a long-term history of two different autoimmune diseases-Hashimoto's disease and vitiligo. Indeed the occurrence in the same patient of three or more autoimmune diseases defines APS. The first classification of APS was suggested by Neufeld and Blizzard in 1980 and it included four main types of APS on the basis of clinical features. The only case of APS type 3B+C was described by Amerio et al in 2006.

Abstract
To determine a possible causative association between autoimmunity and premature ovarian ageing (POA), 394 women undergoing IVF at an academically affiliated private IVF centre were retrospectively evaluated for the presence of autoimmune-related diseases. Out of 162 POA women, 13 (8.0%) demonstrated a history of autoimmune disease(s), while autoimmunity was present in 28 (12.1%) of 232 controls. POA women with poor response (four oocytes or fewer) despite high-dose treatment presented autoimmunity in 7.9%, compared with 12.1% control subjects without autoimmune diseases. When family history was considered (patient and/or first-degree relatives), at least one autoimmune disease was reported in 14 (8.6%) POA and 31 (13.4%) controls with comparable distributions of autoimmune diseases among both groups. Infertile women with premature ovarian ageing and age-appropriate ovarian function show high but comparable prevalences of autoimmune-related diseases. These findings support the assumption that aetiologies other than autoimmune disease lead to POA.

Abstract
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.
