Background. The prevalence of autoimmune thyroid diseases (AITDs), especially Hashimoto’s thyroiditis (HT), has increased dramatically in China. Moreover, China is experiencing the largest scale of urbanization in the world. We intended to explore the relationship between rapid urbanization and HT. Methods. A total of 2946 subjects in Zhejiang Shangyu (SY) (n = 1546) and Jiangsu Nanjing (NJ) (n = 1400) were enrolled in this study. Serum TPOAb, TGAb, and thyrotropin (TSH) were measured, and ultrasonography of the thyroid was performed in all subjects. DNA was extracted from all subjects, and four SNPs were selected for genotyping. Generalized multifactor dimensionality reduction (GMDR) was used to screen the best interaction between genetic factors and environment factors. Results. TPOAb and TGAb concentrations were higher in NJ than in SY (34.60 vs. 14.00 IU/ml and 21.05 vs. 7.50 IU/ml). People in NJ also had higher TPOAb and TGAb positivity rates than those in SY (7.8% vs. 12.7% and 8.7% vs. 16.3%). Logistic regression analysis indicated that rapid urbanization was an independent risk factor for TPOAb (OR = 1.473) and TGAb (OR = 1.689). Genotype TT in rs11675434 was associated with an increased risk of TPOAb positivity both in SY (OR = 2.955) and in NJ (OR = 1.819). GMDR analysis showed a two-locus model (SNP2 × urbanization) and a three-locus model (SNP2 × SNP3 × urbanization), which had testing accuracies of 56.88% and 57.25%, respectively ( P values were 0.001 and 0.001). Conclusion. Rapid urbanization influences the incidence of TPOAb and TGAb positivity. We should pay more attention to thyroid autoimmune disease in areas of China experiencing rapid urbanization.

The past few years have been actively discussing the role of individual macro- and micronutrients as factors regulating the functional activity of organs and systems and reducing the risk of developing a number of diseases, including thyroid diseases. Selenium is one of the most important and intensively studied at present microelements. According to several studies, its low plasma level is associated with an increased risk of developing autoimmune thyroid diseases. In animal experiments, it was shown that a combined deficiency of selenium and iodine leads to more pronounced hypothyroidism than iodine deficiency alone. Some authors believe that cretinism in the newborn is a consequence of the combined deficiency of these two elements in the mother. It is also important that the optimal level of selenium is necessary both to initiate an immune response and to regulate an excessive immune response, as well as chronic inflammation. The review article discusses the relationship between selenium and thyroid pathology, discusses the role of selenium in the physiology of the thyroid gland and in the development of autoimmune diseases. The biochemical aspects of the pathogenesis of thyroid disease are presented.

Introduction, Autoimmune diseases are chronic conditions initiated by the loss of immunological tolerance to self-antigens. They constitute heterogeneous group of disorders, in which multiple alterations in the immune system result in a spectrum of syndromes that either target specific organs or affect the body systematically. Recent epidemiological studies have shown a possible shift of one autoimmune disease to another or the fact that more than one autoimmune disease may coexist in a single patient or in the same family. Numerous autoimmune diseases have been shown to coexist frequently with thyroid autoimmune diseases. Autoimmune thyroid disease and other organ specific non-endocrine autoimmune diseases. This part of the study reviews the prevalence of autoimmune thyroid disease coexisting with: pernicious anaemia, vitiligo, celiac disease, autoimmune liver disease, miastenia gravis, alopecia areata and sclerosis multiplex, and several recommendations for screening have been given. Autoimmune thyroid disease and other organ non-specific non-endocrine autoimmune diseases. Special attention is given to the correlation between autoimmune thyroid disease and rheumatoid arthritis, systemic lupus erythematosus, syndrome Sj?gren, systemic sclerosis and mixed connective tissue disease. Conclusions. Screening for autoimmune thyroid diseases should be recommended in everyday clinical practice, in patients with primary organ-specific or organ non-specific autoimmune disease. Other?wise, in patients with primary thyroid autoimmune disease, there is no good reason of seeking for all other autoimmune diseases, although these patients have a greater risk of developing other autoimmune disease. Economic aspects of medicine require further analyzing of these data, from cost/benefit point of view to justified either mandatory screening or medical practitioner judgment.

In the past 10 years, immune checkpoint inhibitors (ICIs) have become an additional pillar of cancer therapy by activating the immune system to treat a number of different malignancies. Many patients receiving ICIs develop immune-related adverse events (irAEs) that mimic some features of classical autoimmune diseases. Unfortunately, patients with underlying autoimmune conditions, many of whom have an increased risk for malignancy, have been excluded from clinical trials of ICIs due to a concern that they will have an increased risk of irAEs. Retrospective data from patients with autoimmune diseases and concomitant malignancy treated with ICIs are encouraging and suggest that ICIs may be tolerated safely in patients with specific autoimmune diseases, but there are no prospective data to guide management. In this manuscript, we review the relationship between pre-existing autoimmune disease and irAEs from checkpoint inhibitors. In addition, we assess the likelihood of autoimmune disease exacerbations in patients with pre-existing autoimmunity receiving ICI.

AbstractThyroid peroxidase (TPO) is a critical membrane-bound enzyme involved in the biosynthesis of multiple thyroid hormones, and is a major autoantigen in autoimmune thyroid diseases such as Graves’ disease and Hashimoto’s thyroiditis. Here we report the biophysical and structural characterisation of two novel TPO constructs containing only the ectodomain of TPO and lacking the propeptide. Both constructs were enzymatically active and able to bind the patient-derived TR1.9 autoantibody. Analytical ultra-centrifugation data suggests that TPO can exist as both a monomer and a dimer. Combined with negative stain electron microscopy and molecular dynamics simulations, these data show that TR1.9 autoantibody preferentially binds the TPO monomer, revealing conformational changes that bring together previously disparate residues into a continuous epitope. In addition to providing plausible structural models of a TPO-autoantibody complex, this study provides validated TPO constructs that will facilitate further characterization, and advances our understanding of the structural, functional and antigenic characteristics of TPO, a molecule behind some of the most common autoimmune diseases.

Preliminary Study

Autoimmune thyroid diseases (AITDs), including Hashimoto' s thyroiditis (HT) and Graves' disease (GD), are related to environmental and genetic factors. We analyzed the association of cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) gene two polymorphisms (+49 A/G, -318 C/T) with HT and GD development in Polish children, and correlated both polymorphisms with the production of thyroid autoantibodies (TPOAb and TgAb). The study involved 49 AITD patients (age 10-19) with HT (n=25) or GD (n=24) and 69 healthy controls. SNP genotyping was performed using genomic DNA and TaqMan® probes. The obtained results indicated that CTLA-4 +49 GG genotype was significantly more frequent in both HT and GD patients, whereas the AA genotype was more common in controls. CTLA-4-318 CT genotype was significantly more frequent in AITD, and the CC genotype more often occurred in controls. Significantly higher median TPOAb and TgAb values were associated with G allele in HT, and with T allele in GD patients. Concluding, both studied polymorphisms seem to be important genetic determinants of the risk of HT and GD, and appear to be associated with a predisposition to high levels of TAbs and clinical AITD. The obtained results give more information on the distribution of the CTLA-4 polymorphism in Polish AITD children, and further support the proposal that the CTLA-4 gene plays an important role in a TAb production.

Background: Coffee is one of the drinks most often consumed throughout the world and is the second most popular beverage in the world after water. At present, the effect of coffee consumption on the human body is increasingly being studied, especially on the cardiovascular system. Many studies say that coffee consumption can prevent stroke, either directly or indirectly against stroke risk factors by a variety of mechanisms caused by the compounds contained in coffee. However, to date various prospective studies looking at the relationship between coffee consumption and stroke risk are still inconsistent. Objectives: To determine the relationship of coffee consumption with the risk of stroke. Methods: We searched on MEDLINE and PubMed, using the keywords “coffee” or “caffeine” and "stroke or cardiovascular events" which follows the flow and search rules of the Reporting Item Options for Systematic Review and Meta Analysis (PRISMA) to find studies with cohort design in the last 10 years starting in 2009-2019. Discussion: Among 226 citations identified in this systematic review, only 10 studies met the inclusion criteria. Four studies provided evidence that coffee consumption habits were not associated with an increased risk of stroke, while 6 other studies explaining that more coffee consumption has protective benefits against the risk of stroke. Conclusion: Coffee consumption shows a preventive effect on stroke risk. Keywords: caffeine, coffee, relative risk, stroke risk   Latar Belakang: Kopi merupakan salah satu minuman yang paling sering dikonsumsi di seluruh dunia dan menjadi minuman populer kedua di dunia setelah air. Saat ini, pengaruh konsumsi kopi untuk tubuh manusia semakin banyak diteliti, khususnya terhadap sistem kardiovaskular. Banyak penelitian mengatakan bahwa konsumsi kopi dapat mencegah timbulnya penyakit stroke, baik secara langsung atau tidak langsung terhadap faktor risiko stroke dengan beragam mekanisme yang ditimbulkan oleh senyawa yang terkandung dalam kopi. Namun, hingga saat ini beragam studi prospektif yang mengamati hubungan antara konsumsi kopi dan risiko stroke masih belum konsisten. Tujuan: Untuk mengetahui hubungan konsumsi kopi dengan risiko terjadinya stroke. Metode: Pencarian dilakukan pada MEDLINE dan PubMed dengan menggunakan kata kunci “coffee or caffeine” and “stroke or cardiovascular events”. yang mengikuti alur dan kaidah pencarian Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) untuk mencari studi dengan desain cohort dalam rentang waktu 10 tahun terakhir mulai tahun 2009-2019. Pembahasan: Dari 226 sitasi yang teridentifikasi pada systematic review, hanya 10 studi yang sesuai dengan kriteria inklusi. Empat penelitian memberikan bukti bahwa kebiasaan mengonsumsi kopi tidak dikaitkan dengan peningkatan risiko stroke, sedangkan 6 penelitian lainnya, menjelaskan bahwa konsumsi kopi yang lebih banyak memiliki manfaat perlindungan terhadap risiko kejadian stroke.

Depression and fatigue have previously been suggested to share an underlying genetic contribution. The present study aims to investigate and characterize the familiality and genetic relationship between depression and fatigue. The familiality of depression and fatigue was assessed by calculating relative risks, measured by the prevalence ratio, within 643 monozygotic (MZ) and 577 dizygotic (DZ) twin pairs. Bivariate twin modeling was utilized to assess the magnitude of shared heritability between depression and fatigue. Finally, the relationship between depression and fatigue was investigated using the co-twin control method, to determine whether the association is explained by causal or non-causal models. We observed an increased risk of fatigue in co-twins of probands with depression and increased risk of depression in co-twins of probands with fatigue. Higher risks were observed in MZ compared to DZ twin pairs, and bivariate heritability analyses indicated significant genetic components for depression and fatigue, with heritability estimates of 48% and 41%, respectively. Importantly, a significant additive genetic correlation of 0.71 [95% CI = 0.51–0.92) and bivariate heritability of 21% [95% CI = 10–35%] was observed between depression and fatigue. Furthermore, results from the co-twin control method indicate a non-causal genetic relationship that likely explains the association between depression and fatigue. Notably, the contribution of shared genetic factors remained significant, independent of the overlapping symptoms, indicating that the relationship between co-occurring depression and fatigue is primarily due to shared genetic factors rather than overlapping symptomatology.

Purpose of Review. Studies have been published in the field of autoimmune thyroid diseases since January 2005. The review is organized into areas of etiology, autoimmune features, autoantibodies, mechanism of thyroid cell injury, B-cell responses, and T-cell responses. Also it reviews the diagnosis and the relationship between autoimmune thyroid disease, neoplasm, and kidney disorders. Recent Findings. Autoimmune thyroid diseases have been reported in people living in different parts of the world including North America, Europe, Baalkans, Asia, Middle East, South America, and Africa though the reported figures do not fully reflect the number of people infected per year. Cases are unrecognized due to inaccurate diagnosis and hence are treated as other diseases. However, the most recent studies have shown that the human autoimmune thyroid diseases (AITDs) affect up to 5% of the general population and are seen mostly in women between 30 and 50 years. Summary. Autoimmune thyroid disease is the result of a complex interaction between genetic and environmental factors. Overall, this review has expanded our understanding of the mechanism involved in pathogenesis of AITD and the relationship between autoimmune thyroid disease, neoplasm, and kidney disease. It has opened new lines of investigations that will ultimately result in a better clinical practice.
