Autoimmune thyroid disease (AITD) is often observed together with other autoimmune diseases. The coexistence of two or more autoimmune diseases in the same patient is referred to as polyautoimmunity, and AITD is the autoimmune disease most frequently involved. The occurrence of polyautoimmunity has led to the hypothesis that the affected patients suffer from a generalized dysregulation of their immune system. The present review summarizes recent discoveries unravelling the immunological mechanisms involved in autoimmunity, ranging from natural autoimmunity to disease-specific autoimmunity...

OBJECTIVE: The epidemiology of polyautoimmunity in Sjögren's syndrome (secondary Sjögren's syndrome - sSS) is not well defined and has not been investigated before using a systematic approach. We conducted a systematic review of the epidemiology of sSS associated with rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), scleroderma, and myositis, assessing the prevalence rates (PRs) and clinical and serological features of sSS. METHOD: A systematic literature search of PubMed and Embase databases (updated to March 2016) was performed to identify all published data on PR, demographic profile, clinical manifestations, laboratory features, and causes of death associated with sSS...

Polyautoimmunity is defined as the presence of more than one autoimmune disease in a single patient. The exact pathogenic mechanisms responsible for the coexistence of distinct autoimmune diseases within an individual have not been clearly explained. We report a case of a very young girl with the extremely rare co-existence of four distinct autoimmune diseases i.e. juvenile idiopathic arthritis, type 1 diabetes mellitus, coeliac disease and autoimmune hepatitis, recognized based on validated international classification criteria...

BACKGROUND: Juvenile idiopathic arthritis (JIA) is a chronic inflammatory arthritis of unknown origin which can be considered an autoimmune disease (AD). The aim of this study is to analyse the presence of two or more autoimmune diseases (polyautoimmunity) in patients suffering from JIA and to evaluate the occurrence of ADs in their families. METHODS: Seventy-nine patients diagnosed with JIA aged 0-21 years, admitted to the Paediatric Rheumatology Unit, Sant'Orsola-Malpighi Hospital, Bologna were screened for ADs...

AIM: Celiac disease is an autoimmune enteropathy with variable clinical symptoms. Elderly patients can have different manifestations from those of young patients. The aims of the present study were to investigate whether any differences or similarities exist between older and young patients with celiac disease with a special emphasis on concurrent autoimmune diseases. METHODS: Celiac disease patients were stratified as older and younger patients. These two groups were then compared by means of clinical symptoms, laboratory parameters and concurrent autoimmune diseases...

Autoimmune diseases share common immunopathogenic mechanisms (i.e., the autoimmune tautology), which explain the clinical similarities among them as well as their familial clustering. Guillain-Barré syndrome (GBS), an autoimmune peripheral neuropathy, has been recently associated with Zika virus (ZIKV) infection. Based on a series of cases, this review article provides a comparative analysis of GBS associated with ZIKV infection, contrasted with the general characteristics of GBS in light of the autoimmune tautology, including gender differences in prevalence, subphenotypes, polyautoimmunity, familial autoimmunity, age at onset, pathophysiology, ecology, genetics, ancestry, and treatment...

INTRODUCTION: Systemic sclerosis (SSc) is a connective tissue disease of unknown etiology, characterized by a triad of vascular injury, autoimmunity and tissue fibrosis. It is known that a positive family history is the greatest risk factor already identified for the development of SSc in a given individual. Preliminary observation of a high prevalence of polyautoimmunity and of familial autoimmunity in SSc patients support the idea that different autoimmune phenotypes may share common susceptibility variants...

AIM: Elderly patients with autoimmune gastritis might have different symptoms than those of young patients. The aim of the present study was to compare presented symptoms and laboratory parameters associated with autoimmune gastritis in both old and young age groups. METHODS: A total of 355 patients with autoimmune gastritis were stratified into two groups: 65 years or older (n = 119, mean age 69.47 ± 5.027 years), and under 65 years (n = 236, mean age 45...

Polyautoimmunity is defined as the presence of more than one well-defined autoimmune disease (AD) in a single patient. Polyautoimmunity is a frequent condition in Sjögren syndrome (SS) and follows a grouping pattern. The most frequent ADs observed in SS are autoimmune thyroid disease, rheumatoid arthritis, and systemic lupus erythematosus. Main factors associated with polyautoimmunity in SS are tobacco smoking and some genetic variants. The study of polyautoimmunity provides important clues for elucidating the common mechanisms of autoimmne diseases (ie, the autoimmune tautology)...

OBJECTIVES: Familial autoimmunity and polyautoimmunity represent extreme phenotypes ideal for identifying major genomic variants contributing to autoimmunity. Whole exome sequencing (WES) and linkage analysis are well suited for this purpose due to its strong resolution upon familial segregation patterns of functional protein coding and splice variants. The primary objective of this study was to identify potentially autoimmune causative variants using WES data from extreme pedigrees segregating polyautoimmunity phenotypes...

OBJECTIVES: Autoimmune gastritis may be associated with other organ-specific autoimmune disorders, but the prevalence of this association is not entirely quantified. The aims of this study were to investigate the prevalence of autoimmune disorders and evaluate the factors that might affect this association in patients with autoimmune gastritis. METHODS: A total of 320 patients with autoimmune gastritis were retrospectively studied and data on concomitant autoimmune diseases, serum gastrin and chromogranin A levels, anti-Hp IgG, antiparietal cell antibodies, presence of enterochromaffin-like cell hyperplasia and gastric atrophy were gathered for each patient and associations between autoimmune gastritis and studied parameters were explored through descriptive statistics and logistic regression analysis...

LRBA (lipopolysaccharide-responsive and beige-like anchor protein) deficiency associates immune deficiency, lymphoproliferation, and various organ-specific autoimmunity. To date, prevalent symptoms are autoimmune cytopenias and enteropathy, and lymphocytic interstitial lung disease. In 2 siblings from a consanguineous family presenting with early onset polyautoimmunity, we presumed autosomal recessive inheritance and performed whole exome sequencing. We herein report the first case of early-onset, severe, chronic polyarthritis associated with LRBA deficiency...

Studies documenting increased risk of developing autoimmune diseases (ADs) have shown that these conditions share several immunogenetic mechanisms (i.e., the autoimmune tautology). This report explored familial aggregation and segregation of AD, polyautoimmunity, and multiple autoimmune syndrome (MAS) in 210 families. Familial aggregation was examined for first-degree relatives. Segregation analysis was implemented as in S.A.G.E. release 6.3. Data showed differences between late- and early-onset families regarding their age, age of onset, and sex...

Autoimmune thyroid disease (AITD), known as the most common organ-specific autoimmune disorder, is frequently accompanied by other organ and non-organ-specific autoimmune diseases, including rheumatoid arthritis (RA). Although the exact pathogenic mechanisms of the coexistence of autoimmune disorders are still not completely defined, genetics, immune defects, hormones and environmental factors may play key roles in polyautoimmunity. In this review, the prevalence of AITD and antithyroid autoantibodies in RA patients and rheumatic manifestations in association with thyroid autoimmunity are discussed...
