Type1 Diabetes Mellitus

Type 1 diabetes mellitus (T1DM) is an autoimmune disease frequently associated with autoimmune thyroid disease (AITD). The study is conducted at the Specialized Center for Endocrinology and Diabetes-Baghdad at Al-karkh side, during December 2013 up to April 2014. In this study, we investigate the prevalence of anti-thyroid peroxidase (anti-TPO) antibody in(80) type1 diabetic patients with (AITD) and (30) healthy controls .Blood samples are taken for investigation of thyroid tests by using Vitek Immunodiagnstic Assay System (VIDAS).Enzeme Linked Immunosorbent Assay (ELISA) is used to detect anti-thyroid antibody(anti-TPO). The results show that age, gender and BMI (body mass index) are similar in both groups, p>0.05. Among 80 type1 diabetic patients 15(18.8%) are positive. There is a highly significant difference (p0.05) between T3 &T4 and frequency of positive and negative (anti-TPO).

OBJECTIVE: Type 1 diabetes mellitus is frequently associated with autoimmune thyroid disease (ATD). Genetic susceptibility to autoantibody formation in association with ATD and type 1 diabetes mellitus has been described with varying frequencies, but there is still debate about the situation in the Chinese population. We have, therefore, investigated the prevalence of anti-thyroid peroxidase (anti-TPO) in type 1 diabetic patients, and compared the effect of anti-glutamate decarboxylase (anti-GAD) on the thyroid autoimmunity in patients with type 1 diabetes mellitus in Taiwan. SUBJECTS AND METHODS: Two hundred and forty-three subjects with type 1 diabetes mellitus and seventy unrelated normal controls were recruited for the detection of anti-TPO. Two hundred and seventeen sera from two hundred and forty-three type 1 diabetic patients were tested for anti-GAD. RIA and immunoprecipitation were used for anti-TPO and anti-GAD detection respectively. RESULTS: The intra-assay and interassay coefficients of variation of anti-TPO detected by the RIA method ranged from 5.5% to 11.1%. Among 243 type 1 diabetic patients, 53 (21.8%) were positive for anti-TPO. Compared with those without thyroid autoimmunity, there was a female preponderance for the type 1 diabetic patients with thyroid autoimmunity (female:male, 99:91 vs 37:16 respectively). Among the type 1 diabetic patients with thyroid autoimmunity, anti-TPO tended to occur in those of older age or with long-standing disease. The frequency of anti-GAD was 45.6%, (99 of 217), without gender preponderance (males:females, 18.0% vs 27.61%). Compared with those with negative anti-GAD, no significant difference of anti-TPO positivity for the type 1 diabetic patients with positive anti-GAD was found. CONCLUSION: Our data indicated that the RIA method for anti-TPO detection is sensitive and precise for routine clinical use. The presence of anti-TPO in 21.8% of our type 1 diabetic patients confirmed the strong association of ATD and type 1 diabetes mellitus without ethnic differences. The absence of correlation between anti-TPO and anti-GAD in our type 1 diabetic patients suggested genetic heterogeneity in the role of autoimmunity of type 1 diabetes mellitus and ATD among races.

Background: Type 1 diabetes mellitus (T1 DM) is the most common type of diabetes in children. T1DM patients are also at higher risk of other comorbid autoimmune diseases, including autoimmune thyroid disease (AITD), celiac disease (CD). The thyroid-specific immune damage of AITD is strongly associated with elevated serum thyroid peroxidase (TPO). Tissue transglutaminase antibody (tTGA) is a specific antibody and a serological marker of CD. This study aimed to evaluate the positivity of anti - TPO and anti - tTGA in children with T1DM after they were diagnosed. Materials and Methods: This study was conducted from January 2019 to October 2020, included 105 children with T1DM. 44 children matching in aged (1 - 14 years) and gender were taken as control with other diagnoses (16 with viral infection, 24 with short stature, 4 with genetic disorders). The antibodies were checked up for the first time after they were diagnosed. Anti - TPO and anti - tTGA were carried out by ELISA. Results: 55.2% of T1DM children were girls. The anti-TPO was positive in 30.5% of T1DM children compared to 4.5% of children in control group. The anti-tTGA was positive in 7.6% of T1DM children compared to 2.3% of children in control group. Risk of Hashimoto's hypothyroidism was more in children older than 10 years old. 21.9% of children 11 - 14 years old were anti - TPO positive, but it was 16.2%, more common in girls. While, anti - tTGA was positive in 3.85% of children 1 - 5 years old with no difference between boys and girls. Conclusion The most frequent autoimmune disease resulted Hashimoto's hypothyroidism. Girls with T1DM have a higher predisposition to Hashimoto's Hypothyroidism in the 11-14 age group compared to boys. Children with T1DM were found to have a lower predisposition to CD. Children with T1DM have a higher predisposition to develop CD at the age of 1 - 5 years. In conclusion we can say that antibodies to other autoimmune diseases must be performed together with diagnostic examinations for T1DM. Key words: Type 1 diabetes mellitus, Autoimmune Thyroid Disease, Celiac Disease, Thyroid Peroxidase, Tissue Transglutaminase Antibody.

Autoimmune Polyendocrine Syndrome

Type 1 diabetes mellitus (T1D), autoimmune thyroid disease, and autoimmune gastritis often occur together forming the so-called autoimmune polyendocrine syndrome type 3 (APS3). We here report a clinical case of a 74-year-old woman who presented for the first time with severe hyperglycemia and ketoacidosis diagnosed as T1D. Further clinical investigations revealed concomitant severe hypothyroidism with autoimmune thyroid disease and severe cobalamin deficiency due to chronic atrophic gastritis. The diagnosis of type 1 diabetes mellitus was confirmed by the detection of autoantibodies against glutamic acid decarboxylase 65, islet cell antibodies, and anti-insulin autoantibodies. Anti-thyroperoxidase, anti-thyroglobulin, and anti-gastric parietal cell antibodies were also clearly positive. The case emphasized that new onset diabetic ketoacidosis, hypothyroidism, and cobalamin deficiency may simultaneously occur, and one disease can mask the features of the other, thereby making diagnosis difficult. It is noteworthy that an APS3 acute episode occurred in an asymptomatic elder woman for any autoimmune diseases.

Abstract Background The most common coexisting organ-specific autoimmune disease in patients with Type 1 diabetes mellitus (T1DM) is autoimmune thyroid disease (AITD). Many studies have showed prevalence rate of thyroid autoantibodies range from 3.7-35% in T1DM patients, while some of them suggested the associations between thyroid autoantibodies and islet autoantibodies. However, little work has been done about the anti-islet autoimmune status in patients with autoimmune thyroid disease (AITD), and so far there have been no clinical report based on large population about zinc transporter 8 autoantibody (ZnT8A) in patients with AITD. We aimed to explore the presence of islet autoantibodies, ZnT8A, glutamic acid decarboxylase autoantibodies (GADA) and tyrosine phosphatase autoantibodies (IA-2A) compared with thyroid autoantibodies, thyroid peroxidase autoantibodies (TPOAb) and thyroglobulin autoantibodies (TGAb) and thyrotropin receptor autoantibodies (TRAb) in AITD patients. Methods In total 740 AITD patients, 108 type 1 diabetes mellitus (T1DM) patients with AITD, 172 non-autoimmune thyroid disease (nAITD) patients and 115 healthy controls were recruited in the cross-sectional study. Islet autoantibodies, ZnT8A, GADA, IA-2A and thyroid autoantibodies, TPOAb, TGAb, TRAb were detected with Radioimmunoassay and Chemiluminescence. Islet autoantibody relative value was established to compare the distribution of the three islet autoantibodies. Results The prevalence of ZnT8A and GADA in AITD group was significantly higher than that in healthy controls (ZnT8A: 15.00% vs 1.74%, GADA: 7.97% vs 0.87%, both P<0.05). Similarly, the prevalence of IA-2A in AITD group was higher than that in healthy controls (4.19% vs 0%, P<0.05). However, any islet autoantibodies positive rate in AITD group was significantly lower than that in T1DM with AITD group. Analysis of multivariable linear regression suggested that ZnT8A relative value was positively related with GADA relative value (β=0.352, P<0.01) and TPOAb titer (β=0.002, P<0.01), and GADA relative value was also positively related with ZnT8A relative value (β=0.183, P<0.01). Conclusions An increased prevalence of ZnT8A as well as a relatively high prevalence of islet autoimmunity was found in AITD patients, indicating that there is a potential link between thyroid autoimmunity and islet autoimmunity. Trial registration Retrospectively registered.

Autoimmune Thyroid

Autoimmune thyroid disease (AITD) and type 1 diabetes mellitus (T1DM) are two common autoimmune diseases that can occur concomitantly. In general, patients with diabetes have a high risk of AITD. It has been proposed that a complex genetic basis together with multiple nongenetic factors make a variable contribution to the pathogenesis of T1DM and AITD. In this paper, we summarize current knowledge in the field regarding potential pathogenic factors of T1DM and AITD, including human leukocyte antigen, autoimmune regulator, lymphoid protein tyrosine phosphatase, forkhead box protein P3, cytotoxic T lymphocyte-associated antigen, infection, vitamin D deficiency, and chemokine (C-X-C motif) ligand. These findings offer an insight into future immunotherapy for autoimmune diseases.

OBJECTIVE: Thyroid autoantibodies (TA) and thyroid ultrasonography are widely used in the diagnosis of autoimmune thyroid disease (AITD). However, we know little of the significance of having ultrasonographic abnormalities (USabn) without having any other signs of AITD. In a previous population-based study of 105 young patients with type 1 diabetes (T1DM) we found a high prevalence (42%) of USabn. In the present study we evaluate the development of both USabn and TA in a 3-Year follow-up of this cohort. DESIGN: Of the 105 previously investigated children and adolescents with T1DM (aged 5-21 Years), 101 were re-examined. Serum concentrations of tri-iodothyronine (T(3)), thyroxine (T(4)), TSH, thyroid peroxidase antibodies (TPOab) and thyroglobulin antibodies (Tgab), as well as thyroid size and morphology were determined in all patients. RESULTS: During the 3 Years follow-up period, the prevalence of thyroid dysfunction increased from 5 to 8%, the prevalence of TPOab was unchanged at 13%, while the prevalence of Tgab decreased from 14 to 7%. The prevalence of USabn increased from 42 to 49%. Most patients presented USabn at both examinations. Patients with USabn had a higher prevalence of TA than those without USabn (P=0.038) and higher serum levels of TSH (P=0.027). All patients with thyroid dysfunction presented with USabn. However, many patients with USabn had no other signs of AITD. CONCLUSIONS: A high prevalence of thyroid dysfunction, TA and thyroid USabn were found in young patients with T1DM. Thyroid USabn was a sensitive but non-specific marker of AITD and is therefore unsuitable for screening purposes. Instead, we recommend regular screening using serum TSH in the follow-up of young diabetic patients.
