Prevalence of latent and overt polyautoimmunity in type 1 diabetes: A systematic review and meta-analysis. Diabetes Metab Syndr 2024; 18:103087. [PMID: 39074403 DOI: 10.1016/j.dsx.2024.103087] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/28/2024] [Revised: 07/15/2024] [Accepted: 07/20/2024] [Indexed: 07/31/2024]
Abstract
BACKGROUND Patients afflicted by type 1 diabetes (T1D) exhibit polyautoimmunity (PolyA). However, the frequency and distribution of PolyA in T1D is still unknown. OBJECTIVE We conducted a systematic review and meta-analysis to define the prevalence of latent and overt PolyA in individuals with T1D. METHODS Following PRISMA guidelines, a comprehensive search across medical databases identified studies on latent and overt PolyA in T1D. Two researchers independently screened, extracted data, and assessed study quality. A random effects model was utilized to calculate the pooled prevalence, along with its corresponding 95 % confidence interval (CI), for latent PolyA and overt PolyA. Meta-regression analysis was conducted to study the effect of study designs, age, sex, and duration of disease on pooled prevalence. RESULTS A total of 158 articles, encompassing a diverse composition of study designs were scrutinized. The analysis included 270,890 individuals with a confirmed diagnosis of T1D. The gender was evenly distributed (50.30 % male). Notably, our analysis unveiled an overt PolyA prevalence rate of 8.50 % (95 % CI, 6.77 to 10.62), with North America having the highest rates (14.50 %, 95 % CI, 7.58 to 24.89). This PolyA profile was further characterized by a substantial incidence of concurrent autoimmune thyroid disease (7.44 %, 95 % CI, 5.65 to 9.74). Moreover, we identified a notable prevalence of latent PolyA in the T1D population, quantified at 14.45 % (95 % CI, 11.17 to 18.49) being most frequent in Asia (23.29 %, 95 % CI, 16.29 to 32.15) and Oceania (21.53 %, 95 % CI, 16.48 to 27.62). Remarkably, this latent PolyA phenomenon primarily featured an array of autoantibodies, including rheumatoid factor, followed by Ro52, thyroid peroxidase antibodies, and thyroglobulin antibodies. Duration of the disease was associated with a highest frequency of latent (β: 0.0456, P-value: 0.0140) and overt PolyA (β: 0.0373, P-value: 0.0152). No difference in the pooled prevalence by study design was observed. CONCLUSION This meta-analysis constitutes a substantial advancement in the realm of early detection of PolyA in the context of T1D. Individuals with T1D should regularly undergo assessments to identify potential concurrent autoimmune diseases, especially as they age.

Abstract
Objective To screen a general pediatric population for type 1 diabetes (T1D), celiac disease (CD), and autoimmune thyroid disease (AITD) after home capillary sampling. Methods Swedish schoolchildren between 6-9 years and 13-16 years of age were invited to screening by taking a capillary sample at home. Samples were returned by mail and assessed for autoantibodies associated with T1D, CD, and AITD. Persistently autoantibody-positive children were referred for clinical follow-up. Results Of 19,593 invited, 3,527 (18.0%) consented to participate and 2,315/3,527 (65.6%) returned a blood sample of sufficient volume. Hemolysis occurred in 830/2,301 (36.1%) samples. After exclusion of 42 children with previously known T1D, CD, or AITD, and two autoantibody-positive children who declined a confirmatory sample, 2,271/19,593 (11.6%) were included. 211/2,271 (9.3%) had persistent autoantibodies: 60/2,271 (2.6%) with T1D autoantibodies, 61/2,271 (2.7%) with CD autoantibodies, and 99/2,271 (4.4%) with AITD autoantibodies; 9/2,271 (0.4%) were autoantibody positive for ≥1 disease. After clinical follow-up, 3/2,271 (0.1%) were diagnosed with T1D, 26/2,271 (1.1%) with CD, and 6/2,271 (0.3%) with AITD. Children with a first-degree relative (FDR) with T1D, CD, and/or AITD, had higher occurrence of autoantibodies compared to children without an FDR (63/344, 18.3%, vs. 148/1,810, 8.2%) (p < 0.0001, OR 2.52, 95% CI 1.83-3.47), and higher occurrence of screening-detected diagnosis (14/344, 4.1%, vs. 21/1,810, 1.2%) (p < 0.0001, OR 3.61, 95% CI 1.82-7.18). Half of these children screened positive for another disease than the FDR. Conclusion Screening for T1D, CD, and AITD by home capillary sampling in a Swedish general pediatric population detected autoimmunity in 9.3% and undiagnosed disease in 1.5%.

Abstract
AIM The incidence of type 1 diabetes continues to increase. However, the strategies to prevent or reduce its occurrence are inadequate. Therefore, we attempted to investigate if mothers with autoimmune disease were more likely to have children with type 1 diabetes. METHODS We identified 1,288,347 newborns from the Taiwan Maternal and Child Health Database between January 1, 2009, and December 31, 2016, and followed them up to December 31, 2019. We used a multivariable Cox regression model to compare the childhood-onset type 1 diabetes risk between children whose mother had or did not have an autoimmune disease. RESULTS The multivariable model demonstrated significantly higher risks of type 1 diabetes in the children with maternal autoimmune disease (aHR 1.55, 95% CI 1.16-2.08), type 1 diabetes (aHR 11.33, 95% CI 4.62-27.77), Hashimoto's thyroiditis (aHR 3.73, 95% CI 1.70-8.15), and inflammatory bowel diseases (aHR 2.00, 95% CI 1.07-3.76). CONCLUSION This nationwide mother and child cohort study showed a higher risk of type 1 diabetes in the children whose mothers had autoimmune disease, including Hashimoto's thyroiditis, and inflammatory bowel diseases.

Abstract
BACKGROUND Coeliac disease is an autoimmune disorder triggered by ingesting gluten. It affects approximately 1% of the UK population, but only one in three people is thought to have a diagnosis. Untreated coeliac disease may lead to malnutrition, anaemia, osteoporosis and lymphoma. OBJECTIVES The objectives were to define at-risk groups and determine the cost-effectiveness of active case-finding strategies in primary care. DESIGN (1) Systematic review of the accuracy of potential diagnostic indicators for coeliac disease. (2) Routine data analysis to develop prediction models for identification of people who may benefit from testing for coeliac disease. (3) Systematic review of the accuracy of diagnostic tests for coeliac disease. (4) Systematic review of the accuracy of genetic tests for coeliac disease (literature search conducted in April 2021). (5) Online survey to identify diagnostic thresholds for testing, starting treatment and referral for biopsy. (6) Economic modelling to identify the cost-effectiveness of different active case-finding strategies, informed by the findings from previous objectives. DATA SOURCES For the first systematic review, the following databases were searched from 1997 to April 2021: MEDLINE® (National Library of Medicine, Bethesda, MD, USA), Embase® (Elsevier, Amsterdam, the Netherlands), Cochrane Library, Web of Science™ (Clarivate™, Philadelphia, PA, USA), the World Health Organization International Clinical Trials Registry Platform ( WHO ICTRP ) and the National Institutes of Health Clinical Trials database. For the second systematic review, the following databases were searched from January 1990 to August 2020: MEDLINE, Embase, Cochrane Library, Web of Science, Kleijnen Systematic Reviews ( KSR ) Evidence, WHO ICTRP and the National Institutes of Health Clinical Trials database. For prediction model development, Clinical Practice Research Datalink GOLD, Clinical Practice Research Datalink Aurum and a subcohort of the Avon Longitudinal Study of Parents and Children were used; for estimates for the economic models, Clinical Practice Research Datalink Aurum was used. REVIEW METHODS For review 1, cohort and case-control studies reporting on a diagnostic indicator in a population with and a population without coeliac disease were eligible. For review 2, diagnostic cohort studies including patients presenting with coeliac disease symptoms who were tested with serological tests for coeliac disease and underwent a duodenal biopsy as reference standard were eligible. In both reviews, risk of bias was assessed using the quality assessment of diagnostic accuracy studies 2 tool. Bivariate random-effects meta-analyses were fitted, in which binomial likelihoods for the numbers of true positives and true negatives were assumed. RESULTS People with dermatitis herpetiformis, a family history of coeliac disease, migraine, anaemia, type 1 diabetes, osteoporosis or chronic liver disease are 1.5-2 times more likely than the general population to have coeliac disease; individual gastrointestinal symptoms were not useful for identifying coeliac disease. For children, women and men, prediction models included 24, 24 and 21 indicators of coeliac disease, respectively. The models showed good discrimination between patients with and patients without coeliac disease, but performed less well when externally validated. Serological tests were found to have good diagnostic accuracy for coeliac disease. Immunoglobulin A tissue transglutaminase had the highest sensitivity and endomysial antibody the highest specificity. There was little improvement when tests were used in combination. Survey respondents (n = 472) wanted to be 66% certain of the diagnosis from a blood test before starting a gluten-free diet if symptomatic, and 90% certain if asymptomatic. Cost-effectiveness analyses found that, among adults, and using serological testing alone, immunoglobulin A tissue transglutaminase was most cost-effective at a 1% pre-test probability (equivalent to population screening). Strategies using immunoglobulin A endomysial antibody plus human leucocyte antigen or human leucocyte antigen plus immunoglobulin A tissue transglutaminase with any pre-test probability had similar cost-effectiveness results, which were also similar to the cost-effectiveness results of immunoglobulin A tissue transglutaminase at a 1% pre-test probability. The most practical alternative for implementation within the NHS is likely to be a combination of human leucocyte antigen and immunoglobulin A tissue transglutaminase testing among those with a pre-test probability above 1.5%. Among children, the most cost-effective strategy was a 10% pre-test probability with human leucocyte antigen plus immunoglobulin A tissue transglutaminase, but there was uncertainty around the most cost-effective pre-test probability. There was substantial uncertainty in economic model results, which means that there would be great value in conducting further research. LIMITATIONS The interpretation of meta-analyses was limited by the substantial heterogeneity between the included studies, and most included studies were judged to be at high risk of bias. The main limitations of the prediction models were that we were restricted to diagnostic indicators that were recorded by general practitioners and that, because coeliac disease is underdiagnosed, it is also under-reported in health-care data. The cost-effectiveness model is a simplification of coeliac disease and modelled an average cohort rather than individuals. Evidence was weak on the probability of routine coeliac disease diagnosis, the accuracy of serological and genetic tests and the utility of a gluten-free diet. CONCLUSIONS Population screening with immunoglobulin A tissue transglutaminase (1% pre-test probability) and of immunoglobulin A endomysial antibody followed by human leucocyte antigen testing or human leucocyte antigen testing followed by immunoglobulin A tissue transglutaminase with any pre-test probability appear to have similar cost-effectiveness results. As decisions to implement population screening cannot be made based on our economic analysis alone, and given the practical challenges of identifying patients with higher pre-test probabilities, we recommend that human leucocyte antigen combined with immunoglobulin A tissue transglutaminase testing should be considered for adults with at least a 1.5% pre-test probability of coeliac disease, equivalent to having at least one predictor. A more targeted strategy of 10% pre-test probability is recommended for children (e.g. children with anaemia). FUTURE WORK Future work should consider whether or not population-based screening for coeliac disease could meet the UK National Screening Committee criteria and whether or not it necessitates a long-term randomised controlled trial of screening strategies. Large prospective cohort studies in which all participants receive accurate tests for coeliac disease are needed.

Familial autoimmunity in pediatric patients with type 1 diabetes (T1D) and its associations with the severity of clinical presentation at diabetes diagnosis and with coexisting autoimmunity. Hormones (Athens) 2022; 21:277-285. [PMID: 35254657 PMCID: PMC8900107 DOI: 10.1007/s42000-022-00358-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/19/2021] [Accepted: 02/22/2022] [Indexed: 11/05/2022]
Abstract
PURPOSE The aim was to evaluate the impact of familial autoimmunity on the age and severity of type 1 diabetes (T1D) presentation and on the coexistence of other autoimmune diseases. METHODS We retrospectively evaluated the medical records of 121 children/adolescents (male: 63) followed in our Diabetic Clinic from 2002 to 2016. RESULTS Seventy-six patients (62.8%) had at least one relative with an autoimmune disease, Hashimoto's thyroiditis (49.5%) and T1D (22.3%) being the commonest. Children with familial autoimmunity were younger at T1D diagnosis (mean age ± SD) (6.766 ± 3.75). Median fasting c-peptide levels at presentation were not related to familial autoimmunity. Patients with familial autoimmunity more often exhibited GADA autoantibody positivity at diagnosis. The larger the number of the patient's relatives diagnosed with an autoimmune disease, the higher were the patient's GADA levels (Spearman's rho test = 0.19, p = 0.049). Children with a first-degree relative with autoimmunity had a coexisting autoimmune disorder at a significantly higher percentage (p = 0.016). Family history of autoimmunity was negatively associated with the presence of diabetic ketoacidosis (DKA) (p = 0.024). Patients with a relative with T1D less frequently exhibited DKA at diagnosis (12.8 vs. 87.2%, p = 0.003). The presence of DKA was associated with younger age (p = 0.05) and lower c-peptide levels (p = 0.033). CONCLUSIONS Familial autoimmunity was present in 62.8% of children with T1D, autoimmune thyroiditis and T1D being the two most frequent familial autoimmune diseases. Familial autoimmunity reduced the risk of DKA at diagnosis, but these patients were younger and had higher levels of pancreatic autoantibodies and a greater risk of developing additional autoimmune diseases.

Abstract
OBJECTIVE The most common coexisting organ-specific autoimmune disease in patients with type 1 diabetes mellitus (T1DM) is autoimmune thyroid disease (AITD). However, there have been few clinical reports based on a large population about the prevalence of zinc transporter 8 autoantibody (ZnT8A) and other islet autoantibodies in AITD patients. We aimed to explore the presence of islet autoantibodies, ZnT8A, glutamic acid decarboxylase autoantibodies (GADA) and insulinoma-associated antigen 2 autoantibodies (IA-2A) compared with thyroid autoantibodies, thyroid peroxidase autoantibodies (TPOAb) and thyroglobulin autoantibodies (TGAb) and thyrotropin receptor autoantibodies (TRAb) in patients with Graves' disease (GD), Hashimoto's thyroiditis (HT) and T1DM patients with AITD. METHODS Totally, 389 patients with GD, 334 patients with HT, 108 T1DM patients with AITD and 115 healthy controls (HC) were recruited in the study. Islet autoantibodies (ZnT8A, GADA and IA-2A) were detected by radioligand binding assay. Thyroid autoantibodies, TPOAb and TGAb were detected by chemiluminescence assay, and TRAb was detected by RIA. RESULTS The prevalence of ZnT8A, GADA and IA-2A was higher in GD and HT patients than that of HC (ZnT8A: GD 8.48%, HT 10.8% vs HC 1.74%; GADA: GD 7.46%, HT 7.74% vs HC 0.870%; IA-2A: GD 4.88%, HT 3.59% vs HC 0%; All P < 0.05) but lower than that of T1DM subjects with AITD (ZnT8A: 42.6%; IA-2A: 44.4%; GADA: 74.1%; all P < 0.0001). CONCLUSIONS An increased prevalence of ZnT8A as well as GADA and IA-2A was found in both GD and HT patients, indicating that there is a potential link between thyroid autoimmunity and islet autoimmunity.

Abstract
OBJECTIVE Type 1 diabetes (T1D) is frequently associated with other autoimmune diseases (AIDs). Although most of T1D patients are sporadic cases (S-T1D), 10% to 15% have a familial form (F-T1D) involving 2 or more first-degree relatives. This study evaluated the effect of T1D family aggregation and age onset on AIDs occurrence. METHODS In this observational, cross-sectional, case-control, single center study, we enrolled 115 F-T1D and 115 S-T1D patients matched for gender, age, T1D age onset, and duration. With respect to T1D age onset (before or after 18 years), both groups were further subdivided into young- or adult-onset F-T1D and young- or adult-onset S-T1D. The presence of organ-specific antibodies and/or overt AIDs was evaluated. RESULTS The F-T1D group had a higher percentage of AIDs (29.8% vs 18.4%, P = .04) and a significant earlier onset of AIDs at Cox regression analysis (P = .04) than the S-T1D group. Based on multivariate analysis, the adult-onset F-T1D subgroup had the highest prevalence of both additional organ-specific antibodies (60.5%) and overt AIDs (34.9%), whereas the adult S-T1D subgroup was the least frequently involved (29.1% and 12.7%, respectively). In F-T1D patients, offsprings develop T1D and AIDs earlier than their parents do. CONCLUSIONS In T1D patients, familial aggregation and adult-onset of T1D increase the risk for coexistent AIDs. These clinical predictors could guide clinicians to address T1D patients for the screening of T1D-related AIDs.

Abstract
BACKGROUND Patients with type 1 diabetes (T1D) are at risk for other autoimmune diseases (ie, polyautoimmunity). The prevalence and risk factors of this phenomenon have been underreported in adults and ethnic minorities, and data are lacking regarding non-endocrine autoimmune diseases. METHODS Study population data were gathered from HealthFacts, a deidentified patient database compiled from electronic medical records systems in the US. Patients with an International Classification of Diseases diagnosis code specifying T1D were included in the study, whereas those with a diagnosis of type 2 diabetes were excluded. RESULTS The cross-sectional study cohort comprised 158 865 adults with T1D (mean [±SD] age 51.4 ± 18.9 years, 52.5% female). The most common autoimmune diseases were thyroid disease (20.1%), systemic rheumatic diseases (3.4%), rheumatoid arthritis specifically (2.0%), and gastrointestinal autoimmune diseases (1.4%). Most of the autoimmune diseases were more common in women (eg hypothyroidism, hyperthyroidism, celiac disease, rheumatoid arthritis, lupus, and Sjögren syndrome). Caucasians were more likely than other ethnicities to have an additional autoimmune disease. The prevalence of autoimmune diseases increased with increasing age, significantly in women, such that 38.5% of women over 80 years of age had an additional autoimmune disease, compared with 17.9% of women aged ≤29 years. CONCLUSIONS Additional autoimmunity represents a significant comorbidity in patients with T1D. Autoimmune diseases are more common in Caucasians and in women, and increase with age. Clinicians treating patients with T1D should be aware of the risk factors for additional autoimmune diseases.

Prevalence of β-cell antibodies and associated autoimmune diseases in children and adolescents with type 1 diabetes (T1DM) versus type 2 diabetes (T2DM) in Qatar. ACTA BIO-MEDICA : ATENEI PARMENSIS 2018; 89:32-39.

Abstract
INTRODUCTION Type 1 diabetes mellitus (T1DM) is an autoimmune disease with the development of abnormal immune responses to specific β-cell autoantigens in addition to other organ-specific autoimmunity. The most frequent associated disorders are thyroid dysfunctions and celiac disease. There are limited studies in the current literature on the prevalence of associated autoimmunity, especially multiple, in children and adolescents with T1DM and Type 2 diabetes mellitus (T2DM). OBJECTIVES The aim of the present study was to determine the prevalence of autoantibodies and thyroid dysfunctions in a cohort of children and adolescents (aged 0.5-16 years) with T1DM living in Qatar. RESEARCH DESIGN AND METHODS The records of all children and adolescents attending the Pediatric Diabetes Center of Hamad Medical Center, for the past 5 years (from January 2012 to December 2016), were reviewed and all clinical and biochemical data, including β-cell autoimmunity [anti-glutamic acid decarboxylase (GAD) antibodies, anti-islet cell and anti-insulin antibodies (IAA)], thyroid function (Free thyroxine: FT4 and thyroid-stimulating hormone: TSH), anti-thyroid peroxidase antibodies (TPO) and anti-tissue transglutaminase (ATT) were collected at their first presentation (cross-sectional study). Data for patients with T1DM (n=431) and T2DM (n=59) were recorded analyzed and the prevalence calculated and compared with other studies. RESULTS The prevalence of anti-GAD antibodies was 75.5 % in T1DM and 29.3% in T2DM. Anti β-islet antibodies (Ab) were detected in 53.4% of T1DM and 29.4% of T2DM. Anti-insulin Ab were detected in 40.4% of T1DM and 58.3% of T2DM. The three antibodies together were detected in 18.4 % of T1DM and none of T2DM. At presentation, hypothyroidism (FT4 <11.5 pmol/L) was detected in 10.6% of T1DM and 10% of T2DM. Subclinical hypothyroidism was diagnosed in 3.5% of T1DM and 8% of T2DM. High anti TPO was detected in 27.2% of T1DM and 34.6% of T2DM. High TPO with normal thyroid function were found in 22.7% of T1DM and 23.1% of T2DM. ATT IgA was high in 5% of T1DM and 8.7% of T2DM whereas ATT IgG was high in 4.4 % of T1DM and not detected in any patient with T2DM. Mucosal biopsy proved celiac disease in 9 out of 12 patients (75%) with positive ATT IgA and IgG antibodies. CONCLUSIONS Qatar has a relatively high incidence of T1DM compared to incidences reported worldwide. The incidence increased over the period 2012-2015. We report a high prevalence of associated autoimmune abnormalities in our patients with T1DM and T2DM. These data strengthen the argument for routine screening of all children and adolescents with T1DM and T2DM for other autoimmune disorders, particularly the thyroid gland.

Abstract
OBJECTIVES We set out to determine the prevalence of tissue transglutaminase antibodies (anti-tTG) and celiac disease (CD) in children with newly diagnosed type 1 diabetes (T1D) and their first-degree relatives (FDR). The hypothesis was that the individuals with both diabetes and CD form a distinct subgroup in terms of human leukocyte antigen (HLA) class II genetics, islet autoantibodies, and clinical characteristics at diabetes diagnosis. SUBJECTS AND METHODS This population-based observational study included 745 index children with T1D and their 2692 FDR from the Finnish Pediatric Diabetes Register. CD was ascertained by registers, patient records, and screening anti-tTG positive individuals for further testing. RESULTS Among the index children, 4.8% had anti-tTG at diabetes diagnosis, and at the end of the study 3.2% had CD. Among the relatives, 2.9% had anti-tTG (4.8% mothers, 2.4% fathers, and 2.1% siblings), and 2.5% had CD (4.6% mothers, 2.1% fathers, and 1.4% siblings). Anti-tTG and CD associated with the HLA DR3-DQ2 haplotype. The usual female predominance of CD patients was observed in relatives (70%) but not among index children (46%). The index children with both diseases had a lower number of detectable islet autoantibodies than those with diabetes alone. CONCLUSIONS The children with double diagnosis differed from those with diabetes alone in HLA genetics, humoral islet autoimmunity directed against fewer antigens, and in the lack of usual female preponderance among CD patients. Compared with 61% of the anti-tTG positive relatives, only 36% of anti-tTG positive index children developed CD implicating transient anti-tTG positivity at diagnosis of T1D.

Abstract
BACKGROUND Type 1 diabetes (T1D) is frequently associated with other autoimmune conditions such as autoimmune thyroiditis, coeliac disease (CD) and Addison's disease. There are sparse data on the prevalence of antibodies against these conditions in Indian patients with T1D. This study aims to evaluate prevalence of these T1D associated autoantibodies in Indian patients. METHODS Two hundred and fifty-eight patients with T1D were recruited from the Bangalore Diabetes Hospital and the Vydehi Institute of Medical Sciences and Research Centre (VIMS) for the study. Participants diagnosed with diabetes before the age of 18 years, as per the American Diabetes Association (ADA) criteria, and who were classified as T1D based on clinical grounds were recruited for the study. Anti-thyroid peroxidase antibody (TPO) and IgA tissue transglutaminase antibody (tTG) were estimated in all the patients. 21-Hydroxylase antibody (21-OHAb) were estimated in 170 patients. All assays were done by commercial immunoassay. Eighty-eight unrelated age-matched healthy controls were chosen for comparison. RESULTS The mean age of T1D patients was 14.33 years. The mean duration of diabetes was 4.88 years. Anti-TPO was positive in 43 (16.7%) patients with T1D as compared to 3 (3.4%) in controls. IgA tTG was positive in 12 (4.65%) patients with T1D and was absent in controls. 21-OHAb was positive in two (1.1%) patients with T1D and was absent in controls. Both patients who had positive 21-OHab had the other two antibodies. Five patients had positive anti-TPO and IgA-tTG antibodies. CONCLUSIONS Anti-TPO antibody was the most prevalent antibody in patients with T1D. Anti-TPO and IgA-tTG antibodies were significantly higher than in the control population. Further studies will be required to assess the clinical significance of these positive antibodies.

Abstract
BACKGROUND AND AIMS Type 1 diabetes (T1D) is associated with other autoimmune diseases (AIDs), but the prevalence and associated predictive factors for these comorbidities of T1D across all age groups have not been fully characterized. MATERIALS AND METHODS Data obtained from 25 759 participants with T1D enrolled in the T1D Exchange Registry were used to analyze the types and frequency of AIDs as well as their relationships to gender, age, and race/ethnicity. Diagnoses of autoimmune diseases, represented as ordinal categories (0, 1, 2, 3, or more AIDs) were obtained from medical records of Exchange Registry participants. RESULTS Among the 25 759 T1D Exchange participants, 50% were female, 82% non-Hispanic white, mean age was 23.0 ± 16.9 years and mean duration of diabetes was 11 years. Of these participants, 6876 (27%) were diagnosed with at least one AID. Frequency of two or more AIDs increased from 4.3% in participants aged younger than 13 years to 10.4% in those aged 50 years or older. The most common AIDs were thyroid (6097, 24%), gastrointestinal (1530, 6%), and collagen vascular diseases (432, 2%). Addison's disease was rare (75, 0.3%). The prevalence of one or more AIDs was increased in females and non-Hispanic whites and with older age. CONCLUSIONS In the T1D Exchange Clinic Registry, a diagnosis of one or more AIDs in addition to T1D is common, particularly in women, non-Hispanic whites, and older individuals. Results of this study have implications for both primary care and endocrine practice and will allow clinicians to better anticipate and manage the additional AIDs that develop in patients with T1D.

Abstract
Celiac disease (CD) is an autoimmune small intestinal mucosal disorder that often presents with diarrhea, malabsorption and weight loss. Often, one or more associated endocrine disorders may be associated with CD. For this review, methods involved an extensive review of published English-language materials. In children and adolescents, prospective studies have demonstrated a significant relationship to insulin-dependent or type 1 diabetes, whereas in adults, autoimmune forms of thyroid disease, particularly hypothyroidism, may commonly co-exist. In some with CD, multiple glandular endocrinopathies may also occur and complicate the initial presentation of the intestinal disease. In others presenting with an apparent isolated endocrine disorder, serological screening for underlying subclinical CD may prove to be positive, particularly if type 1 diabetes, autoimmune thyroid or other autoimmune endocrine diseases, such as Addison’s disease are first detected. A number of reports have also recorded hypoparathyroidism or hypopituitarism or ovarian failure in CD and these may be improved with a strict gluten-free diet.

Abstract
The aim of this study was to better understand the frequency of autoimmune thyroid and diabetes antibodies in patients with type 1 diabetes mellitus (T1DM) compared with their siblings. Glutamic acid decarboxylase antibodies (GADA), islet cell antibodies (ICA), insulin autoantibodies (IAA), and thyroid autoantibodies were studied in all subjects. The rates of positive GADA and IAA were significantly higher in probands compared to in siblings (p<0.001) or controls (p<0.001). All pancreatic autoantibodies were not significantly different between the siblings and the healthy controls. Thyroid antiperoxidase antibody (TPOAb) and antithyroglobulin antibody (TGAb) were significantly different between the probands and the control subjects (p=0.002 and p=0.018, respectively). The rates of TPOAb and TGAb positivity in siblings were higher than in those of the controls, but there was no significant difference between the two groups. However, thyroid autoimmunity (TA) was significantly different among the groups (p=0.004). Siblings of the TA-positive probands were shown to have a greater prevalence of thyroid antibodies than did the controls (p=0.022), but siblings of the TA-negative probands did not have such a prevalence compared with the control subjects. The prevalence of pancreatic and thyroid antibodies positivity in probands was statistically significant compared with the siblings and the controls. Siblings of TA-positive probands revealed a greater prevalence of thyroid antibodies than did the controls. Therefore, the screening for TA in siblings, particularly siblings of TA-positive probands, is as important as it is in probands.

Abstract
Thyroid disease and diabetes mellitus, the most common disorders in endocrine practice, are not infrequently associated in the same subject. An altered thyroid function may affect glucose tolerance and worsen metabolic control in patients with diabetes. Thyrotoxicosis increases the risk of hyperglycemic emergencies, while a clinically relevant hypothyroidism may have a detrimental effect on glycemic control in diabetic patients. The association of alterations in thyroid function with diabetes mellitus may adversely affect the risk of cardiovascular and microvascular complications resulting from diabetes. Moreover, the treatments used for both diabetes and thyroid disease, respectively, can impact one other. Finally, multinodular goiter, but not thyroid carcinoma, was shown to be more prevalent in type 2 diabetes mellitus. Aim of the present Position Statement is to focus on the evidence concerning the association of thyroid disease and diabetes mellitus and to provide some practical suggestions for an updated clinical management.

OBJECTIVE Thyroid diseases are common in individuals with type 1 diabetes mellitus (T1DM) and should be investigated annually in these individuals. The aim of this study was to evaluate the frequency of thyroid diseases in first degree relatives (FDR) of patients with T1DM. SUBJECTS AND METHODS Eighty individuals (40 patients with T1DM and 40 FDR) were interviewed and blood was sampled for thyroid-stimulating hormone (TSH), free thyroxine (FT4) and thyroid peroxidase (TPO) antibodies measurement. Autoantibodies against glutamic acid decarboxylase 65 (GAD65), islet antigen-2 (IA2) and autoantibodies against insulin (AAI) were measured in FDR. RESULTS We found a similar prevalence of thyroid dysfunction in patients with T1DM and their FDR (22.5% vs. 27.5%; p = 0,79). There were no differences in serum TSH levels (p = 0.29), FT4 (p = 0,45), frequency of abnormal TSH (p = 0.28), positive TPO antibodies (p = 0.13), titers of TPO antibodies (in positive cases) between patients with T1DM and their FDR (p = 0.94). CONCLUSIONS Thyroid abnormalities seem to be common not only in patients with T1DM but also in their FDR, which suggests that screening strategies for thyroid diseases might also be useful to these individuals.

Abstract
OBJECTIVE Monogenic diabetes (MD) is rare and can often be confused with type 1 diabetes (T1D) in a pediatric cohort. We sought to determine clinical criteria that could optimally identify candidates for genetic testing of two common forms of MD that alter therapy: glucokinase (GCK) and hepatocyte nuclear factor 1 alpha (HNF1α). RESEARCH DESIGN AND METHODS We performed a retrospective chart review of 939 patients with a presumed diagnosis of T1D, 6 months-20 yr of age, and identified four clinical criteria that were unusual for T1D and could warrant further evaluation for MD: (i) negative pancreatic autoantibodies, (ii) evidence of prolonged endogenous insulin production, or (iii) strong family history of diabetes in multiple generations. One hundred and twenty-one patients were identified as having one or more of these high-risk clinical criteria and were offered screening for mutations in GCK and HNF1α; 58 consented for genetic testing. RESULTS Of 58 patients with presumed T1D who underwent genetic testing, four were found to have GCK and one had HNF1α. No patients with only one high-risk feature were found to have MD. Of 10 patients who had two or more high risk criteria, five had MD (50%). CONCLUSION A high frequency of MD from mutations in GCK/HNF1α may be identified among pediatric diabetic patients originally considered to have T1D by performing genetic testing on those patients with multiple clinical risk factors for MD.

Abstract
OBJECTIVE To analyze the prevalence of juvenile idiopathic arthritis (JIA) and diabetes end points in pediatric patients with type 1 diabetes. STUDY DESIGN Patients with type 1 diabetes, recorded from 1995 up to September 2013 in the Diabetes Patienten Verlaufsdokumentation database (n = 54,911, <16 years of age, 47% girls), were analyzed. The patients' height, weight, and body mass index SDS, glycosylated hemoglobin A1c (HbA1c); insulin dose; hypertension and dyslipidemia prevalence; rate of hypoglycemic events; and ketoacidosis were compared between patients with and without JIA. To adjust for age, sex, diabetes duration, and migration background, data were analyzed in hierarchic multivariable regression models. RESULTS The prevalence of JIA in type 1 diabetes was 106 of 54,911 patients; 66% were girls. Diabetes onset was earlier in children with JIA (7.2 years vs 8.3 years, P = .04). Children with JIA were smaller (SDS: -0.22 vs 0.09, P = .004). Correspondingly, weight SDS was lower in patients with JIA (-0.02 vs 0.22, P = .01). Body mass index SDS did not differ. HbA1c was marginally lower in children with JIA (63 mmol/mol [8.0%] vs 67 mmol/mol [8.3%], P = .06). Insulin requirement was greater in patients with JIA (1.03 vs 0.93 insulin units/weight/day, P = .003). Hypertension and dyslipidemia were comparable in both groups. CONCLUSIONS The JIA-prevalence in patients with type 1 diabetes (0.19%) was considerably greater than in the general population (0.05%). Growth is influenced negatively by JIA. Surprisingly, HbA1c was somewhat lower in children with JIA, possibly because of a more intensive treatment or a latent hemolysis caused by the inflammation.

Abstract
Type 1 diabetes (T1D) and celiac disease (CD) are autoimmune diseases with clinical and pathogenic overlap. The mean prevalence of CD in patients with T1D is about 8 %. Classic intestinal symptoms of CD may not be present in T1D leading to the recommendation for active case finding in this higher risk group. Screening is done with sensitive and specific serologies including tissue transglutaminase (tTG) IgA and deaminated gliadin peptide (DGP) IgA and IgG. Positive serologies are confirmed by the presence of villous atrophy and increased intraepithelial lymphocytes on duodenal biopsy. A strict gluten free diet is recommended, although this can pose challenges for T1D patients who already have dietary restrictions. In aggregate, it appears as if the gluten free diet may help T1D management. T1D and CD have overlapping genetic and environmental risk factors. Among these, non-HLA genetic factors and the gut microbiome are among recent developments that will be discussed in this review.

Abstract
OBJECTIVE Based on the concept of clustering autoimmunity, children with a positive family history of autoimmunity could be expected to have a different pathogenetic form of type 1 diabetes (T1D) and thus a stronger autoimmune reactivity against β-cells and an increased prevalence of the HLA-DR3-DQ2 haplotype. DESIGN AND METHODS We tested this hypothesis in a cross-sectional observational study from the Finnish Pediatric Diabetes Register. HLA class II genotypes and β-cell autoantibodies were analyzed, and data on the extended family history of autoimmunity and clinical markers at diagnosis were collected with a structured questionnaire from 1488 children diagnosed with T1D under the age of 15 years (57% males). RESULTS Only 23 children (1.5%) had another autoimmune disease (AID) known at diagnosis, and they had a milder metabolic decompensation at diabetes presentation. One-third (31.4%) had at least one relative with an AID other than T1D with affected mothers being overrepresented (8.2%) compared with fathers (2.8%). The children with a positive family history of other AIDs had higher levels of islet cell antibodies (P=0.003), and the HLA-DR3-DQ2 haplotype in the children was associated with celiac disease in the extended family (P<0.001), but not with an increased frequency of autoimmune disorders, in general. CONCLUSIONS Approximately one-third of children with newly diagnosed T1D have a first- and/or second-degree relative affected by an AID. Our data do not consistently support the hypothesis of differential pathogenetic mechanisms in such children.

Abstract
Type I diabetes (T1D) is an autoimmune disease characterized by destruction of insulin-producing β-cells in the pancreas. Although several islet cell autoantigens are known, the breadth and spectrum of autoantibody targets has not been fully explored. Here the luciferase immunoprecipitation systems (LIPS) antibody profiling technology was used to study islet and other organ-specific autoantibody responses in parallel. Examination of an initial cohort of 93 controls and 50 T1D subjects revealed that 16% of the diabetic subjects showed anti-gastric ATPase autoantibodies which did not correlate with autoantibodies against GAD65, IA2, or IA2-β. A more detailed study of a second cohort with 18 potential autoantibody targets revealed marked heterogeneity in autoantibody responses against islet cell autoantigens including two polymorphic variants of ZnT8. A subset of T1D subjects exhibited autoantibodies against several organ-specific targets including gastric ATPase (11%), thyroid peroxidase (14%), and anti-IgA autoantibodies against tissue transglutaminase (12%). Although a few T1D subjects showed autoantibodies against a lung-associated protein KCNRG (6%) and S100-β (8%), no statistically significant autoantibodies were detected against several cytokines. Analysis of the overall autoantibody profiles using a heatmap revealed two major subgroups of approximately similar numbers, consisting of T1D subjects with and without organ-specific autoantibodies. Within the organ-specific subgroup, there was minimal overlap among anti-gastric ATPase, anti-thyroid peroxidase, and anti-transglutaminase seropositivity, and these autoantibodies did not correlate with islet cell autoantibodies. Examination of a third cohort, comprising prospectively collected longitudinal samples from high-risk individuals, revealed that anti-gastric ATPase autoantibodies were present in several individuals prior to detection of islet autoantibodies and before clinical onset of T1D. Taken together, these results suggest that autoantibody portraits derived from islet and organ-specific targets will likely be useful for enhancing the clinical management of T1D.

Abstract
A 26-year-old male patient suffering from Type 1 diabetes mellitus got admitted with abdominal pain and high blood sugars. On further evaluation, he was found to have normal anion gap metabolic acidosis without ketonuria and urinary pH was alkaline. The patient was diagnosed as Type 1 renal tubular acidosis (RTA) (distal RTA) and was managed by alkali replacement in addition to control of blood sugars. The association of Type 1 RTA with Type 1 diabetes mellitus has been rarely reported in the literature. The association needs a different attention as diagnosis and management of diabetic ketoacidosis in such cases will be tricky. The case presented here is the first of its kind from our part of the world and second as far as English literature is concerned.

Abstract
AIMS Type 1 diabetes and autoimmune thyroiditis are common autoimmune diseases characterized by the presence of autoantibodies against tissue-specific components. Non-thyroid-specific autoantibodies are frequent in patients with autoimmune thyroiditis. The prevalence of Type 1 diabetes autoantibodies in patients with autoimmune thyroiditis is unknown. METHODS The prevalence of Type 1 diabetes autoantibodies (GAD and IA2) was analysed in 236 Sardinian children and adolescents with autoimmune thyroiditis. GAD and IA2 antibodies were measured at the time of the diagnosis of autoimmune thyroiditis and re-evaluated after 1 year in the children who were shown to be positive. Autoantibody prevalence was evaluated in 949 healthy age-matched controls. RESULTS The prevalence of GAD and/or IA2 antibodies was 8% in the children and adolescents with autoimmune thyroiditis and 4.1% in control subjects (P = 0.017). When Type 1 diabetes autoantibodies were separately analysed, the difference remained significant for IA2 (3.39% in autoimmune thyroiditis vs. 1.16% in control subjects, P = 0.012), but not for GAD (5.1% in autoimmune thyroiditis vs. 3.79% in control subjects, P = 0.367). Seven of 10 children with autoimmune thyroiditis and detectable Type 1 diabetes autoantibodies at the diagnosis remained positive after 1 year. In the course of 2 years of follow-up, two patients who were positive for Type 1 diabetes autoantibodies at the time of diagnosis of autoimmune thyroiditis developed diabetes. CONCLUSIONS This is the first study reporting the prevalence of Type 1 diabetes autoantibodies in a selected cohort of genetically homogeneous children and adolescents with autoimmune thyroiditis. The main finding was that the prevalence of Type 1 diabetes autoantibodies and of newly diagnosed Type 1 diabetes in patients with autoimmune thyroiditis was significantly higher than that observed in the general paediatric population, suggesting that children with autoimmune thyroiditis are at increased risk of developing Type 1 diabetes.

Abstract
Celiac disease (CD) is one of the most frequent autoimmune disorders occurring in Type 1 diabetes mellitus (T1DM). The prevalence of CD in T1DM varies from 3 to 16%, with a mean prevalence of 8%. The clinical presentation of CD in T1DM is classified as symptomless in approximately half of cases, but a more accurate analysis often discloses a wide array of symptoms suggestive of CD. Both T1DM and CD show the same genetic background and an abnormal small intestinal immune response with inflammation and a variable grade of enteropathy. Serological screening for CD should be performed in all T1DM patients by means of antibodies to tissue transglutaminase at T1DM onset. T1DM patients found to be celiacs must be treated by a gluten-free diet. Potential CD cases (especially when asymptomatic) should be kept on a gluten-containing diet with a careful clinical and antibody follow-up, since many of them will not develop villous atrophy.

Abstract
UNLABELLED Diabetes mellitus is a common autoimmune endocrine disorder associated with organ-specific autoantibodies which are frequently detected at the time of diagnosis. Some of these antibodies are specific to the pancreas (GAD, IA2, ICA) while others are related to different autoimmune diseases. AIM OF THE STUDY To define the prevalence of thyroid autoimmune disease in Libyan patients with type 1 diabetes mellitus (T1DM) since no similar studies have been performed in Libya. MATERIALS AND METHODS Blood samples were collected from 218 patients with T1DM who are followed by the Pediatric Department, Tripoli Medical Center, Libya. All sera were analyzed in Italy (Laboratory of Immunopathology and Allergy, Udine). The patients were composed of 123 females (56.4%) and 95 males (43.6%), mean age 12.2 ± 4.6 years (range 2.1-24.5 years), mean duration of diabetes 4.7 ± 4.0 years (range 0.1-17.5 years). Sera were tested for anti-thyroperoxidase (TPO) and anti-thyroglobulin antibodies (TG). TSH and FT4 concentrations were measured in all subjects. GAD, IA-2 was also measured. RESULTS Of the diabetic children, 23.4% were positive for anti-microsomal peroxidase antibodies (TPO-Ab) and 7.8% for antithyroglobulin antibodies (TG-Ab); whereas 6.9% of the patients were positive for both TPO-Ab and TG-Ab. Of the T1DM patients who were positive for TPO-Ab, 66.6% were females. The majority (57%) of the patients who were positive for TPO had diabetes for longer than 5 years. Five patients (2.3%) had evidence of subclinical hypothyroidism whereas two patients (0.9%) had overt hypothyroidism. Two patients had subclinical hyperthyroidism and two (0.9%) had overt hyperthyroidism. Interestingly, 16.2% of patients were positive for both thyroid and pancreatic antibodies. CONCLUSIONS The prevalence of autoimmune thyroid disease in type 1 diabetic patients is higher than in the general population. A routine screening strategy should be implemented with the determination of anti-thyroid antibodies and TSH in type 1 diabetic patients, particularly in girls, and in patients with diabetes of more than 5 years duration. Patients who have positive TPO antibodies may need the assessment of thyroid function at shorter intervals.

Abstract
BACKGROUND Type 1 diabetes (T1D) is a clinically heterogeneous disease. The presence of associated autoimmune diseases (AAIDs) may represent a distinct form of autoimmune diabetes, with involvement of specific mechanisms. The aim of this study was to find predictors of AAIDs in the Type 1 Diabetes Genetics Consortium data set. METHODS Three thousand two hundred and sixty-three families with at least two siblings with T1D were included. Clinical information was obtained using questionnaires, anti-GAD (glutamic acid decarboxylase) and anti-protein tyrosine phosphatase (IA-2) were measured and human leukocyte antigen (HLA) genotyping was performed. Siblings with T1D with and without AAIDs were compared and a multivariate regression analysis was performed to find predictors of AAIDs. T1D-associated HLA haplotypes were defined as the four most susceptible and protective, respectively. RESULTS One or more AAIDs were present in 14.4% of the T1D affected siblings. Age of diabetes onset, current age and time since diagnosis were higher, there was a female predominance and more family history of AAIDs in the group with AAIDs, as well as more frequent anti-GAD and less frequent anti-IA-2 antibodies. Risk and protective HLA haplotype distributions were similar, though DRB1*0301-DQA1*0501-DQB1*0201 was more frequent in the group with AAIDs. In the multivariate analysis, female gender, age of onset, family history of AAID, time since diagnosis and anti-GAD positivity were significantly associated with AAIDs. CONCLUSIONS In patients with T1D, the presence of AAIDs is associated with female predominance, more frequent family history of AAIDs, later onset of T1D and more anti-GAD antibodies, despite longer duration of the disease. The predominance of certain HLA haplotypes suggests that specific mechanisms of disease may be involved.

Abstract
BACKGROUND Type 1 diabetes (T1D) patients are at risk for additional autoimmune diseases (AID). OBJECTIVE To compare the characteristics of associated autoimmunity among familial (parent-offspring and sib-pair) subgroups and sporadic T1D patients. PATIENTS AND METHODS Data regarding AID in T1D patients and their nuclear family members were extracted from medical files of 121 multiplex T1D families (58 parent-offspring, 63 sib-pairs) and 226 sporadic controls followed between 1979 and 2008. RESULTS The prevalence of associated autoimmunity was similar in familial and sporadic cases (33.6 vs. 32.7%). The frequency of additional AID and percentage of patients with two or more coexistent AID were significantly higher among sib-pairs than parent-offspring (p = 0.05 and p = 0.04, respectively). The median time elapsed between diagnosis of T1D and occurrence of additional autoimmunity tended to be shorter in the sib-pairs. Only in familial cases did a positive autoimmune family background predict the development of coexistent autoimmunity (OR = 2.11, CI [1.0, 4.49] p = 0.05). CONCLUSIONS Among sib-pairs with T1D, the higher prevalence of additional AID, the increased number of diseases per person, and the relatively earlier appearance of associated AID suggest an increased susceptibility for coexistent autoimmunity in this subgroup. Positive family history for autoimmunity in multiplex T1D families increased their risk for co-occurrence of AID.

Abstract
BACKGROUND Patients with diabetes mellitus are at an increased risk of thyroid disease. The frequency of thyroid dysfunction in diabetic patients is higher than that of the general population and up to a third of patients with type-1 diabetes (T1DM) ultimately develop thyroid dysfunction. Unrecognised thyroid dysfunction may impair metabolic control and add to cardiovascular disease risk in diabetic patients. AIMS Our aims were to review the current literature on the association between thyroid dysfunction and diabetes mellitus, to highlight relevant clinical implications, and to examine present thyroid disease screening strategies in routine diabetes care. RESULTS The pleiotropic effects of thyroid hormones on various metabolic processes are now better understood. Uncontrolled hyperthyroidism in diabetic patients may trigger hyperglycaemic emergencies while recurrent hypoglycaemic episodes have been reported in diabetic patients with hypothyroidism. Furthermore, thyroid dysfunction may amplify cardiovascular disease risk in diabetic patients through inter-relationships with dyslipidaemia, insulin resistance and vascular endothelial dysfunction. However, the significance of subclinical degrees of thyroid dysfunction remains to be clarified. While these developments have implications for diabetic patients a consensus is yet to be reached on optimal thyroid screening strategies in diabetes management. CONCLUSIONS The increased frequency of thyroid dysfunction in diabetic patients and its likely deleterious effects on cardiovascular and metabolic function calls for a systematic approach to thyroid disease screening in diabetes. Routine annual thyroid testing should be targeted at diabetic patients at risk of thyroid dysfunction such as patients with T1DM, positive thyroid autoantibodies or high-normal TSH concentrations.

Abstract
Type 1 diabetes mellitus (1 DM) resulting from immunological damage to pancreatic islets (cells is the most common immune-mediated, endocrine metabolic disorder in children with evidence suggesting that type 1 DM is a T-cell-mediated autoimmune disease. About 5% of people with a major polyendocrine autoimmune syndrome develop type 1 DM. Autoimmune thyroid disease is the most frequent autoimmune disease with type 1 DM. An estimated 7% of children with type 1 DM develop Celiac disease within six years of diagnosis. To determine the prevalence of Celiac disease and thyroid disorders among children with type 1 DM, together with their first degree relatives, and to estimate the prevalence of DM among the first degree relatives of diabetic children, 300 type 1 DM children with 1950 first degree relatives were matched with 600 controls together with their 3,900 first degree relatives were screened in a case control study for autoimmune diseases (Celiac disease, thyroid disorders) and the first degree relatives of cases and controls were screened for type 1 DM. Celiac disease and thyroid disorders were insignificantly higher in cases than in controls. Similar findings were seen in 1 st degree relatives of cases compared to controls, with a significant difference in Celiac disease. Type 1DM prevalence was significantly higher in 1st degree relatives of cases than controls. Conclusion: Target screening for Celiac disease and thyroid diseases in type 1 DM children is necessary, but screening 1st degree relatives of diabetic children for auto-immune diseases remains controversial.

Abstract
Objective The apoptotic DNA levels in blood leukocytes of patients with type 2 diabetes (T2D) and thyroid dysfunctionism were evaluated. Materials and methods Single-cell gel electrophoresis (comet assay) detects migration of DNA from individual cell nuclei following alkaline treatment. Comet assay pattern was studied in individuals with T2D, hypothyroid (HT), hyperthyroid (HeT), and patients suffering from both diabetes mellitus and HT (HT + DM). Results were compared with the normal subjects (n = 9 in each group). The percentage apoptotic cell populations were calculated from the tail length. Results T2D patients showed 92.24% of cell damage compared to HT or HeT patients (51.04% or 54.64%, respectively). Further, increase in cell damage was also observed in HT + DM subjects (P < 0.05). Pharmacologic therapy significantly influenced cell damage. However, age and duration of disease did not show any definite influence on apoptosis. Conclusion Dependence of disease seems to be the major contributor of the cell damage. However, thyroid dysfunction did not show any deleterious effects on individual cells under the study.

Abstract
Celiac disease (CD) presents a wide clinical spectrum. There are asymptomatic or oligosymptomatic forms, which are difficult to diagnose. Since patients with untreated CD can develop severe complications, early diagnosis of these forms is important. Consequently, in groups at risk for CD, such as patients with type 1 diabetes (DM1), screening through determination of antigliadin (AGA), anti-tissue transglutaminase (ATG) and antiendomysial antibodies (EMA) is recommended. In the present study, 463 DM1 patients were screened for these antibodies. Patients who were positive for one or more were offered an upper endoscopy to obtain distal duodenum biopsies. Histological lesions, when present, were classified using Marsh's classification. Of the 463 patients, 62 (13.4%) were positive for at least one of the three antibodies, and 42 accepted to undergo an endoscopy. Fourteen patients (3% of the DM1 patients) were histologically diagnosed with CD. Most of these patients had no symptoms of CD, although some showed laboratory findings frequent in CD. The presence of clinical or analytical data compatible with CD was independent of the grade of histological lesions. Finally, we calculated the sensitivity and positive predictive value for each antibody. The most sensitive were ATG and EMA. Because of the technical simplicity of determining ATG with ELISA, in our opinion, this test should be the option of choice for screening.

Abstract
OBJECTIVES To estimate the prevalence of type 1 diabetes mellitus (DM1) and celiac disease association and to verify the existence of celiac disease symptoms, as well as the occurrence of other autoimmune diseases among the patients, their first-degree relatives and the possible influences of celiac disease in diabetes control. METHODS It was done a cross-sectional study with 195 patients that answered a questionnaire about gastrointestinal symptoms and the occurrence of autoimmune diseases in their first-degree relatives. IgA was measured and antiendomysial antibody (EMA) was screened. The patients with positive EMA were submitted to intestinal biopsy. Those with celiac disease confirmed by biopsy (case group) were paired with DM1 patients without celiac disease (control group) according to age on diabetes diagnosis, diabetes duration and gender. RESULTS EMA was positive in nine patients. In seven of them the biopsy has confirmed celiac disease (4.0%). Comparing the cases with controls, the gastrointestinal symptoms were significantly more frequent in the first group, but there was no difference between the groups regarding to the occurrence of autoimmune disease among the first-degree relatives and regarding to the control of diabetes (z weight, z height, insulin dose, HbA1c). CONCLUSIONS The prevalence found was 4.0%. This sample of celiac patients showed a predominance of gastrointestinal symptoms, although the celiac disease did not influence the diabetes control.

Abstract
The concept of autoimmune aetiology of some cases of chronic urticaria (CU) has been supported by several observation including wheal-and-flare reaction induced by intradermal injection of autologous serum as well as association with other autoimmune diseases, in particular Hashimoto's thyroiditis (HT). It is known that activated platelets may actively participate in immune-inflammatory processes. Therefore, we assessed whether autoimmune phenomenon associated with CU influence the systemic platelet activity measured by circulating level of platelet factor 4 (PF-4). Plasma level of PF-4 was analysed using enzyme-linked immunosorbent assay in twelve women with strong positive response to autologous serum skin test (ASST) suffering from CU, twelve female patients with strong positive ASST suffering from both CU and untreated, HT as well as sixteen healthy women. All the subjects were clinically and biochemically euthyroid. There were no statistically significant differences between the CU patients with or without euthyroid HT and plasma PF-4 level in healthy controls. In patients with both CU and thyroiditis, plasma level of PF-4 did not correlate significantly with the level of antibodies against thyroperoxidase. It seems that circulating level of the platelet-derived chemokine is not increased in CU patients with positive response to ASST, regardless the occurrence of euthyroid HT.

Abstract
Type 1 A diabetes mellitus (T1AD) results from the autoimmune destruction of the insulin producing pancreatic beta-cells. The largest contribution to genetic susceptibility comes from several genes located in the major histocompatibility complex on chromosome 6p21.3 (IDDM1 locus), accounting for at least 40% of the family aggregation of this disease. The highest-risk human leukocyte antigen HLA genotype for T1AD is DR3-DQA1*0501-DQB1*0201/DR4-DQA1*0301-DQB1*0302, whereas -DR15-DQA1*0102-DQB1*0602 haplotype is associated with dominant protection. Three other T1D loci associated with predisposition are the Variable Number for Tandem Repeats (VNTR) near the insulin gene (IDDM2), which accounts to 10% of genetic susceptibility, the Cytotoxic T-Lymphocyte-associated Antigen (CTLA-4)(IDDM 12) and the Protein Tyrosine Phosphatasis Nonreceptor-type 22 (PTPN22). Many other gene suspected to predispose to autoimmunity have been investigated. T1AD is frequently associated with autoimmune thyroid disease, celiac disase, Addison s disease and many other autoimmune diseases, characterized by organ-specific autoantibodies and related to the same genetic background. Using these autoantibodies, organ specific autoimmunity may be detected before the development of clinical disease preventing significant morbidity.

Abstract
AIMS/HYPOTHESIS Thyroid autoimmunity clusters with other endocrine and non-endocrine forms of autoimmunity. The aim of this study was to determine the chronological appearance of thyroid autoantibodies in relation to other forms of autoimmunity in at-risk children. METHODS The BABYDIAB study follows children of parents with type 1 diabetes. Children born in Germany between 1989 and 2000 were recruited at birth and followed up at 9 months and at 2, 5, 8, 11, 14 and 17 years. Antibodies to thyroid peroxidase were measured in samples taken at the last study visit in 1,489 children and in all previous samples in children who tested positive. Islet antibodies and antibodies to 21-hydroxylase and transglutaminase were also measured in all children. Median follow-up was 8 years. RESULTS The cumulative risk for developing antibodies to thyroid peroxidase was 20.3% (95% CI 12.3-28.3) by age 14 years. The risk was increased in girls (adjusted HR 2.0; 95% CI 1.2-3.4; p = 0.008), in children who had multiple first-degree family history of type 1 diabetes (adjusted HR 3.3; 95% CI 1.4-8.0; p = 0.006) and in children who also had antibodies to GAD (adjusted HR 3.0; 95% CI 1.5-5.9; p = 0.001). Thyroid peroxidase antibody appearance was most common from age 8 years and was often the last autoantibody to develop in children with other autoantibodies. CONCLUSIONS/INTERPRETATION Among children of patients with type 1 diabetes, the appearance of thyroid autoantibodies is frequent, is not synchronous to the appearance of other autoantibodies and is most common in late childhood and adolescence.

Abstract
O diabetes melito tipo 1 (DM1) freqüentemente encontra-se associado à doença auto-imune da tireóide (DAT). A prevalência de DAT varia de 3% a 50% entre diabéticos, e é maior também entre seus familiares, comparada à população geral. OBJETIVOS: Investigar a prevalência da DAT em pacientes com DM1, avaliar possíveis diferenças de comportamento clínico-evolutivo do DM1 entre diabéticos com e sem DAT e estudar a prevalência de DAT nos familiares dos pacientes diabéticos. MATERIAIS E MÉTODOS: Os prontuários de 124 diabéticos tipo 1 foram revisados e coletados os dados referentes à função e aos anticorpos tireoidianos; pacientes com e sem DAT foram comparados em relação à média de Hb glicosilada, complicações agudas e crônicas, idade ao diagnóstico e tempo de evolução do DM, dose de insulina e outros. Um estudo caso-controle foi realizado com 54 familiares em primeiro grau destes pacientes; foram avaliadas a função tireoidiana e a presença de anticorpos antitireoidianos em 32 familiares de diabéticos sem DAT e 22 familiares de diabéticos com DAT. RESULTADOS: As prevalências de DAT e de disfunção hormonal entre os diabéticos foram de 35,5% e 19,3%, respectivamente. Quanto à avaliação dos parâmetros de evolução do DM1, comportamento clínico e controle metabólico não houve diferenças significantes entre os diabéticos com e sem DAT. Houve maior prevalência de DAT nos familiares de diabéticos com DAT do que no grupo dos familiares dos diabéticos sem DAT, sem diferença significativa quanto à prevalência de disfunção hormonal. CONCLUSÕES: A prevalência de doença auto-imune de tireóide em diabéticos e em seus familiares é elevada, justificando-se, nesses casos, a investigação rotineira da função tireoidiana, particularmente dos familiares de primeiro grau de diabéticos com DAT.

Abstract
OBJECTIVE To asses the prevalence of celiac disease and to evaluate the clinical effects of a gluten-free diet on metabolic control and growth in children and adolescents with type 1 diabetes mellitus (DM1). PATIENTS AND METHODS We performed a retrospective study of 261 patients with DM1. Diagnosis of celiac disease was based on the presence of endomysium and tissue transglutaminase antibodies in serum and was confirmed by intestinal biopsy. The impact of a gluten-free diet on metabolic control (mean annual HbAlc values), growth (height and annual growth velocity) and nutritional status (body mass index) was evaluated. Patients diagnosed with DM1 and subsequently with celiac disease were compared with a control group of patients with DM1 only. RESULTS Twenty-one (8%) of the 261 diabetic patients were diagnosed with celiac disease and 19% also had another associated autoimmune disease. No significant differences were found in growth or metabolic control after withdrawal of gluten from the diet. CONCLUSIONS We found a high prevalence of celiac disease in our type 1 diabetes population. A gluten-free diet had no effects on metabolic control of diabetes or on height or weight. Nevertheless, given the high prevalence of celiac disease and the possible development of long-term complications, such as lymphoma and osteoporosis, we recommend systematic screening in all diabetic patients, especially in the first 5 years after diagnosis of DM1.

Abstract
BACKGROUND AND AIMS Recent studies have shown that celiac disease (CD) could affect 0.5% to 3% of the general population, including Mexican Mestizos, which represents a complex mixture of genetics, and constitutes the core of Mexican and Latin American populations. However, the association between CD and other conditions, specifically type-1 diabetes mellitus, in this population remains unknown. Thus, our aim was to determine the prevalence of both serologic and biopsy proven CD in Mexican Mestizo adults with type-1 diabetes. METHODS Over a 6-month period, serum samples obtained from consecutive Mexican Mestizo adult patients (age >or=18 y) with type-1 diabetes were tested with a new generation human recombinant protein based IgA tissue transglutaminase enzyme-linked immunosorbent assay commercial kit. All patients with positive serologic test results underwent upper gastrointestinal endoscopy and small intestinal biopsies to confirm CD. RESULTS Eighty-four type-1 diabetic patients were included (62 women, mean age 28.9+/-9 y). Overall, 9 patients (9/84) were positive for IgA tissue transglutaminase with a point prevalence of 10.7% (95% CI, 4%-17%). Seven patients agreed to undergo endoscopy. Five subjects had biopsy-proven CD (5.9%, 95% CI, 1.9%-13.3%). One patient had chronic diarrhea and other abdominal bloating; whereas the remaining 3 were asymptomatic. CD associated type-1 diabetic patients tended to have higher hemoglobin A1c levels (P=0.07), reflecting poor glycemic control. CONCLUSIONS As in other populations, we demonstrated a high prevalence of biopsy-proven CD (5.9%) among Mexican Mestizo patients with type-1 diabetes. Clinicians should be aware of this common association in this ethnic group.

Abstract
OBJECTIVE The purpose of this study was to investigate the presence of diabetes, thyroid, and celiac diseases (CD)-related autoantibodies in children with type 1 diabetes (DM1) and their siblings. MATERIALS AND METHODS The study population included 57 children with DM1, aged 11.7+/-4.5 years and their 89 healthy siblings, aged 11.0+/-5.4 years. Autoantibodies to glutamic acid decarboxylase (GAD65), islet cell (ICAs), insulin (IAAs), antiendomisial antibody (EMA), thyroid peroxidase, thyroglobulin, and thyrotropin receptor antibodies were studied both in diabetic patients and their siblings. RESULTS The frequencies of GAD65, ICAs and IAAs positivity were found to be 63.2, 56.1 and 84.2% in patients with DM1 and 53.9, 24.4 and 3.4% in their siblings, respectively. The frequencies of autoimmune thyroid diseases (ATD) as determined by positive thyroid-related autoantibodies were 38.6 and 21.4% (p=0.024) among patients with DM1 and siblings, respectively. Subclinical hypothyroidism or hyperthyroidism was detected in 5.3% of patients with DM1 but in none of their siblings. EMA was positive in 3.5% of diabetic patients and 1.1% of their siblings. CONCLUSIONS Our findings supported the view that children with DM1 should be screened annually for ATD. Relatively lower frequency of CD in the present study indicated that screening for CD-related autoantibodies might be postponed to older ages in asymptomatic patients. The present findings also suggested that the screening for diabetes- (especially GAD65) and thyroid diseases-related autoantibodies in siblings may ensure some useful information about the clinical course.

Abstract
Macrophages as an early stage of immune responses form a bridge between innate and acquired immunity and shape the adaptive immune response. The immunoregulatory functions of macrophages in hosts with a prolonged exposure to a diabetic milieu remain to be determined. The levels, phenotype, and immunity including antigen-presenting ability, phagocytosis and immunogenicity of F4/80+ splenic macrophages (SPMs), and peritoneal exudates macrophages (PEMs) were detected in age-matched control mice and mice with streptozotocin (STZ)-induced diabetes for 16 weeks. The numbers of F4/80+ SPMs and PEMs significantly decreased in STZ-induced diabetic mice, compared with age-matched non-diabetic mice (control) at 16 weeks after diabetes induction. Functional analysis showed that F4/80+ SPMs and PEMs in STZ-induced diabetic mice exhibit significantly lower immunogenicity and nonopsonic phagocytosis to allogeneic T cells than those of control mice both in vitro and in vivo. Coincidently, the antigen-presenting capacity of F4/80+ PEMs, but not F4/80+ SPMs, in mice with STZ-induced diabetes for 16 or more weeks is also significantly lower than that of control mice. Our results showed that total cell number and immune function of F4/80+ macrophages were significantly defective in mice with a prolonged exposure to a diabetic milieu, which may be a mechanism responsible for the increased macrophage-related complications in diabetic patients such as the high prevalence of infection and cardiovascular mortality.

Abstract
To clarify the contribution of Cblb to the development of type1 diabetes (T1D),
we investigated Japanese younger-onset T1D patients. We sequenced the cblb gene in 10 T1D
patients and screened the identified mutations in 109 Japanese T1D patients and 100 normal
subjects. In addition to four previously reported synonymous single nucleotide
polymorphisms (SNPs), we identified two novel nonsynonymous variants (786 C>T (A155V)
and 1718 A>G (N466D)). The A155V mutation was found in one subject with Basedow’s
disease whose mother also carried both the mutation and Basedow’s disease. The N466D
mutation was found in 6 T1D cases including a subject who was classified as fulminant T1D.
We found no significant differences in the allele frequency of these SNPs among T1D and
control subjects, suggesting that the contribution of cblb to the genetic susceptibility
to T1D might not be high for Japanese younger–onset T1D.

Abstract
In the past, celiac disease was believed to be a chronic enteropathy, almost exclusively affecting people of European origin. The availability of new, simple, very sensitive and specific serological tests (anti-gliadin, anti-endomysium and anti-transglutaminase antibody assays) have shown that celiac disease is common not only in Europe and in people of European ancestry but also in the developing countries where the major staple diet is wheat (Southern Asia, the Middle East, North West and East Africa, South America), both in the general population and in the groups at risk. Gluten intolerance thus appears to be a widespread public health problem and an increased level of awareness and clinical suspicion are needed in the New World where physicians must learn to recognize the variable clinical presentations (classical, atypical and silent forms) of celiac disease. In the developing countries, both serological screening in the general population and serological testing in groups at risk are necessary for an early identification of celiac patients. The gluten-free diet poses a challenging public health problem in the developing countries, especially since commercial gluten-free products are not available.

Abstract
AIMS Autoimmune diseases such as Addison's or coeliac disease can contribute to hypoglycaemia or malabsorption and are more common in Type 1 diabetes (T1DM). This brief report describes the prevalence of known and newly detected autoimmune disease in clinical islet transplant candidates with longstanding T1DM and severe hypoglycaemia and/or glycaemic lability who are routinely screened for coexisting autoimmune disease. METHODS One hundred and twenty-four C-peptide negative T1DM subjects [77 (62%) female, mean age 44 +/- 9 years, diabetes duration 28 +/- 11 years, body mass index 24.9 +/- 3.5 kg/m(2)] with indications for clinical islet transplantation at the University of Alberta were screened for autoimmune disease by history and measurement of anti-transglutaminase antibodies (positive > 10 U/ml), 09.00 h cortisol (followed by adrenocorticotrophic hormone-stimulation if < 495 nmol/l) and thyroid-stimulating hormone to determine the prevalence of coeliac disease, Addison's disease and autoimmune thyroid disease, respectively. RESULTS Forty per cent of subjects had one or more coexisting autoimmune disease. The prevalence of autoimmune disease was 35%, coeliac disease 8% and Addison's disease 1.6%. In 11 individuals (9%), one or more autoimmune disease were newly detected (seven coeliac disease and five thyroid disease). Seven of 10 cases of coeliac disease were newly detected. A gluten-free diet in individuals with newly diagnosed coeliac disease reduced gastrointestinal symptoms, but indications for clinical islet cell transplantation persisted. CONCLUSIONS Coexisting autoimmune disease is common in candidates for clinical islet cell transplantation. Screening in this group identified a substantial number of previously unrecognized cases. Clinicians should consider the presence of autoimmune disease even in the absence of classical symptoms.

Abstract
AIM The purpose of this national multicenter prospective study by the French EVADIAC group was to investigate the possibility that continuous intraperitoneal insulin infusion using an implanted pump (CIpii) increases the risk of autoimmune disease in type 1 diabetic patients as it increased anti-insulin immunogenicity. METHODS Prevalence of clinical (Hashimoto's disease, hyperthyroidism, gastric atrophic disease and vitiligo) and subclinical (presence of anti-thyroperoxidase antibodies, anti-intrinsic factor antibodies, abnormal TSH levels) autoimmune diseases was estimated by comparing two groups of patients already treated by either CIpii (n=154) or external pump (CSII) (n=121) for an average of 6 years. Incidence of autoimmune disease was determined by comparing the same measurements one year after inclusion. RESULTS No significant difference was observed for the total prevalence of clinical and subclinical auto-immune thyroid and gastric di-seases (35.6% and 3.2% respectively in the CIpii group versus 40.4% and 2.6% in the CSII group). No significant difference for the incidence of clinical and subclinical auto-immune diseases was observed: 7.2% and 0% in CIpii and 7.3% and 1.7% in CSII. CONCLUSION As previously shown AIA (anti-insulin antibodies) levels were higher in CIpii than in CSII (32.9% vs 20.2%, P<0.0001) but no correlation was observed with either clinical or subclinical autoimmune disease. This large-scale study eliminates the possibility that CIpii increases the risk of autoimmune disease.

Abstract
OBJECTIVES This study aimed at evaluating the screening of thyroïditis and coeliac disease, in a population of children and adolescents with type 1 diabetes, and at comparing the appearance of antibodies specific for these 2 diseases as a function of age. PATIENTS AND METHODS The study included 370 children and adolescents, 179 girls and 191 boys, aged 13.8 +/- 4.4 yr and with diabetes for 7.1 +/- 3.8 yr. Auto-immune thyroïditis was screened using antimicrosomal and antithyroglobulin auto-antibodies, at a mean rhythm of 3 tests per patient (1 every 2 yr), associated with dosages of TSH and FT4. Coeliac disease was screened using antigliadin (+/- antiendomysium) auto-antibodies, at a mean rhythm of 2 tests per patient, and was confirmed by duodenojejunal biopsy. Antithyroïd auto-antibodies were correlated with age following the "censured data analysis" type approach. RESULTS Antithyroïd autoantibodies were found in 42 patients (11.4%), of whom 9 were treated for hypothyroïdism and 1 for Basedow disease, and coeliac disease autoantibodies were found in 9 patients (3.2% of tested patients). The cumulated frequency of antithyroïd auto-antibodies increased regularly with age and was significantly higher in girls, reaching 28% in girls and 12% in boys around 18 yr of age. As a consequence of this evolution, antithyroïd auto-antibodies were frequently found at the time of diagnosis of diabetes when it declared after 10 yr of age, while they often became positive secondarily when diabetes occurred before 10 yr of age. Coeliac disease specific auto-antibodies appeared much earlier and were found at the time of diagnosis of diabetes or at the first screening test. CONCLUSION Antithyroïd autoantibodies are increasingly frequent with age in children with type 1 diabetes, and become very elevated in girls. The rhythm for screening should be adapted to this evolution of autoantibodies with age, which is very different between thyroïditis and coeliac disease.
