Background. Many studies have shown that NLRC4 inflammasome polymorphisms are associated with a variety of autoimmune diseases, but the associations between NLRC4 polymorphisms and autoimmune thyroid diseases (AITDs) are unclear. Our research was aimed at identifying the correlations between NLRC4 polymorphisms and AITDs. Methods. Hi-SNP high-throughput genotyping technology was used for detecting four single-nucleotide polymorphisms (SNPs) of NLRC4 in 1005 AITDs patients (including 629 Graves’ disease and 376 Hashimoto’s thyroiditis) and 781 healthy controls. Results. Compared with healthy controls, the allele frequencies and genotype distribution of rs385076 were statistically related to AITDs (P=0.016 and P=0.048, respectively) and Hashimoto’s thyroiditis (P=0.022 and P=0.046, respectively). Before adjusting for age and gender, rs385076 and AITDs had a significant association in three models of allele model, dominant model, and homozygous model. After adjusting for age and gender, in the above three models, there is still a clear relationship between them. Before adjusting for age and gender, there were prominent discrepancy between rs385076 and Hashimoto’s thyroiditis in the allele model (OR=0.81, 95% CI 0.67-0.97; P=0.021) and the dominant model (OR=0.73, 95% CI 0.57-0.94; P=0.014), after adjusting for age and gender, rs385076 and Hashimoto’s thyroiditis were significantly related to allele model, dominant model, and homozygous model. However, rs455060, rs212704, and rs675712 were not related to AITDs in our study. Conclusion. NLRC4 rs385076 was found to have a significant association with Hashimoto’s thyroiditis for the first time. It laid a foundation for the disclosure of the pathogenesis of AITDs, and provided a possible treatment prospect for HT.

Abstract Background Recent researches suggest that the CD160/HVEM/LIGHT/BTLA signaling pathway may contribute to the pathogeneses of autoimmune diseases, but the relationship between CD160 polymorphisms and autoimmune thyroid disease (AITD) has not been reported yet. This study aimed to evaluate the associations between CD160 polymorphisms and AITD. Methods A total of 1017 patients with AITD (634 Graves’ disease and 383 Hashimoto’s thyroiditis) and 856 unrelated healthy controls were recruited into our study. Odds ratios (ORs) with 95% confidence interval (95%CI) were calculated through logistic regression analyses. The CD160 SNPs were detected using Hi-SNP high-throughput genotyping. Results There was a statistically significant difference between Graves’ disease patients and the control group with respect to both the genotype distribution (P = 0.014) and allele frequency of rs744877 (P = 0.034). A significant association of CD160 rs744877 with AITD was observed before adjusted age and gender under a dominant model (OR = 0.79, 95%CI 0.66–0.95; P = 0.013) and an additive model (OR = 0.77, 95%CI 0.64–0.94, P = 0.008), and was also observed after adjusted age and gender under a dominant model (OR = 0.78, 95%CI 0.65–0.95; P = 0.011) and an additive model (OR = 0.76, 95%CI 0.63–0.93, P = 0.007). A significant association of rs744877 with Graves’ disease was observed under an allele model (OR = 0.84, 95%CI 0.71–0.98, P = 0.027), a dominant model (OR = 0.74, 95%CI 0.60–0.91; P = 0.005), and an additive model (OR = 0.72, 95%CI 0.58–0.90, P = 0.004). Multivariate logistic regression analyses suggested that the association remained significant after adjustment for age and gender. However, rs744877 was not related to Hashimoto’s thyroiditis. Furthermore, CD160 rs3766526 was not significantly related to either Graves’ disease or Hashimoto’s thyroiditis. Conclusion This is the first identification of the association of CD160 rs744877 with Graves’ disease. Our findings add new data to the genetic contribution to Graves’ disease susceptibility and support the crucial role of the CD160/HVEM/LIGHT/BTLA pathway in the pathogenesis of Graves’ disease.

Background: The study of the natural killer (NK) immune compartment could provide important findings to help in the understanding of some of the pathogenetic mechanisms related to autoimmune thyroid diseases (Graves’ disease (GD) and Hashimoto’s thyroiditis (HT)). Within this context, it was suggested that alterations in NK cell cytotoxicity (NKCC) and NK production of cytokines might occur in subjects with GD and HT, whereas the normalization of NK functions could potentially contribute to the prevention of the onset or the progression of both diseases. Objective: Due to the hypothesis of alterations in NK in autoimmune thyroid diseases, we were interested to evaluate NKCC in GD and HT patients and to modulate NK function and secretory activity with cytokines and dehydroepiandrosterone sulfate (DHEAS) in an attempt to normalize NK cell defect. Design: We studied 13 patients with recent onset Graves’ disease, 11 patients with Hashimoto’s thyroiditis at first diagnosis and 15 age-matched healthy subjects. Methods: NK cells were concentrated at a density of 7.75 × 106 cells/ml by negative immunomagnetic cell separation and validated by FACScan as CD16 + /CD56 + cells. NK cells were incubated with interleukin-2 (IL-2) and interferon-β (IFN-β) and co-incubated with DHEAS at different molar concentrations for measuring NKCC and the secretory pattern of tumor necrosis factor-α (TNF-α) from NK cells. Results: Lower spontaneous, IL-2- and IFN-β-modulated NKCC was demonstrated in GD and HT patients compared with healthy subjects (P < 0.001). A decrease in spontaneous and IL-2-modulated TNF-α release from NK cells was also found in both groups of patients (P < 0.001). The co-incubation of NK cells with IL-2/IFN-β + DHEAS at different molar concentrations (from 10−8 to 10−5 M/ml/NK cells) promptly normalized NKCC and TNF-α secretion in GD and HT patients. Conclusions: A functional defect of a subpopulation of NK immune cells, involving both NKCC and the secretory activity, was demonstrated in newly-diagnosed GD and HT patients. This defect can be reversed by a dose-dependent treatment with DHEAS. The impairment of NK cell activity in autoimmune thyroid diseases could potentially determine a critical expansion of T/B-cell immune compartments leading to the generation of autoantibodies and to the pathogenesis of thyroid autoimmunity.

Background/Aims: The IKZF3 gene encodes a zinc-finger protein that plays an important role in the proliferation and differentiation of B lymphocytes. Autoimmune thyroid diseases (AITDs), mainly include Graves’ disease (GD) and Hashimoto’s thyroiditis (HT), are probably caused by the aberrant proliferation of B cells. The objective of this study was to explore the association between IKZF3 polymorphisms and AITDs. Methods: We examined 915 AITD patients (604 GD and 311 HT) and 814 healthy controls. IKZF3 variants (rs2941522, rs907091, rs1453559, rs12150079 and rs2872507) were tested by PCR-ligase detection reaction. Results: It was manifested that that the minor alleles of the five loci increased susceptibility to GD (p<0.05 for rs2941522, and p<0.01 for rs907091, rs1453559, rs12150079 and rs2872507) but in HT patients, these loci showed no significant difference compared with controls. Similarly, the genotype distributions of GD patients manifested obvious differences in all these loci compared with the control group, whereas no statistical differences were observed between HT patients and controls. Furthermore, bioinformatics tools were used to analyze rs1453559, rs12150079 and rs907091. These variants were believed to be the transcription regulator. Conclusion: It is the first time we reported the association between the IKZF3 polymorphisms and GD, indicating that IKZF3 gene tends to bean important risk factor for the development of GD.

The objective of this study was to investigate whether IRF7 polymorphisms are associated with autoimmune thyroid diseases (AITDs). We selected three single nucleotide polymorphisms (SNPs) of IRF7, namely, rs1061501, rs1131665, and rs1061502 for genotyping using PCR-based ligase detection reaction (LDR) method in a total of 1659 participants (592 with Graves’ disease, 297 with Hashimoto’s thyroiditis, and 770 healthy controls). Gene-disease and genotype-clinical phenotype associations were evaluated for the three SNPs. Our results showed that the AG genotype and the minor allele G frequency of rs1131665 and rs1061502 in AITD patients were both higher than those of the controls (rs1131665: AG genotype: P=0.017, OR=1.968; allele G: P=0.018, OR=1.946; rs1061502: AG genotype: P=0.029, OR=1.866; allele G: P=0.031, OR=1.847). Subgroup analysis also showed that the AG genotype and the minor allele G frequency of rs1131665 and rs1061502 in Graves’ disease patients were both higher than those of the controls (rs1131665: AG genotype: P=0.015, OR=2.074; allele G: P=0.016, OR=2.048; rs1061502: AG genotype: P=0.034, OR=1.919; allele G: P=0.035, OR=1.898). Furthermore, the allele G frequency of rs1061501 was associated with Graves’ ophthalmopathy (P=0.035, OR=1.396). No significant difference in IRF7 polymorphisms was found between Hashimoto’s thyroiditis patients and controls. Our study has revealed for the first time that IRF7 is a susceptibility gene for AITD, especially for Graves’ disease and Graves’ ophthalmopathy.

ABSTRACT Clinical significance of autoantibodies to parietal cells (PCA) in patients with autoimmune thyroid diseases (ATD) remains contradictory. AIM: To characterize the frequency of PCA in patients with ATD; to clarify the role of gender and age in PCA positivity; to analyze the association of PCA with gastric or haematologic symptoms and with the levothyroxine dose required to achieve a serum TSH level within the normal range in treated Hashimoto’s thyroiditis (HT) patients. PATIENTS AND METHODS: PCA were measured using ELISA in 137 HT patients, divided into tree subgroups according to the thyroid function: group I included subjects with normal thyroid function; group II included patients with hypothyroidism, in group III were enrolled subjects treated with levothyroxine (LT4). We also studied the PCA positivity in 14 patients with active Graves’ disease and in 23 healthy controls. RESULTS: PCA positivity was found in 51 patients with autoimmune thyroid diseases, with an overall prevalence of 33.8%. No significant differences in PCA were observed between the groups of HT patients. The frequency of PCA in both genders was similar and there were no difference depending on age. In 7.3% of HT patients in different stages of disease we found clinically relevant gastric and/or haematologic symptoms; in 70% of them PCA were positive (OR = 5.5; 95% CI: 1.2 - 28.4; p = 0.009). PCA positive hypothyroid HT patients required higher LT4 doses than PCA negative (1.46 μg/kg vs 1.24 μg/kg, p = 0.04). CONCLUSIONS: PCA may be present in different stages in HT patients; this does not depend on the severity of disease. PCA concentrations may predict symptoms of atrophic gastritis in patients with Hashimoto’s thyroiditis. PCA positive HT patients require higher replacement doses of LT4. Presence of anemia, particularly microcytic anemia, was suggestive of undiagnosed atrophic gastritis.

Abstract Background B lymphocyte activating factor (BAFF) is a growth factor regulating B lymphocytes survival and maturation. Serum BAFF levels were elevated in patients affected with autoimmune thyroid diseases (AITD), including Graves’ disease (GD) and Hashimoto’s thyroiditis (HT). The aim of this study is to explore the association of expression levels of BAFF and its receptors with AITD. Methods Fifty-two GD patients, 39 Hashimoto’s thyroiditis (HT) patients and 23 healthy controls (HC) were recruited in this study. Serum BAFF levels were measured by ELISA. Expression of BAFF receptors, including BAFF receptor 3 (BR3) and transmembrane activator and calcium-modulating and cyclophilin ligand interactor (TACI), on B lymphocytes were analyzed by flowcytometry. Effects of steroids on serum BAFF levels and expression of BR3 and TACI were also observed in 10 patients with Graves’ orbitopathy (GO) receiving steroids therapy. Results Serum BAFF levels were significantly elevated from 0.93 ± 0.24 ng/ml in HC to 1.18 ± 0.33 ng/ml in GD (P = 0.0027) and 1.02 ± 0.24 ng/ml in HT (P = 0.0331). BR3 expression on peripheral B lymphocytes were elevated in GD (mean MFI: 4.52 ± 2.06 in GD vs. 3.00 ± 0.87 in HC, P = 0.0015), while TACI expression on peripheral B lymphocytes were decreased in GD without significance (mean MFI: 7.96 ± 4.06 in GD vs. 9.10 ± 3.37 in HC, P = 0.1285). Expression of BR3 and TACI was not changed significantly in HT patients. Steroids significantly suppressed serum BAFF concentrations (from 1.18 ± 0.27 ng/ml to 0.97 ± 0.10 ng/ml, P = 0.0364) and BR3 expression in GO patients (mean MFI from 6.26 ± 4.91 to 4.05 ± 1.58, P = 0.0083). Conclusions Altered expression of BAFF and its receptor may mediate the autoimmunity in GD. Restoring the normal expression profile of receptors for BAFF could be a new strategy to treat GD.

Objectives. Assess the prevalence of thyroid nodules and predictors of malignant origin in patients with autoimmune thyroid diseases. Patients and Methods. Retrospective study including 275 patients, 198 with Graves' disease and 77 with Hashimoto’s thyroiditis. Clinical and demographical data, ultrasonographical nodule characteristics, total thyroid volume and histological characteristics were recorded. Results. Graves’ disease: the prevalence of thyroid nodules and thyroid carcinoma were 27.78% and 5.05%, respectively. Older age (OR = 1.054; 95% CI = 1.029–1.080) and larger thyroid volumes (OR = 1.013; 95% CI = 1.003–1.022) increased the chance of nodules. Younger age (OR = 1.073; 95% CI = 1.020–1.128) and larger thyroid volume (OR = 1.018; 95% CI = 1.005–1.030) predicted thyroid carcinoma. Hashimoto’s thyroiditis: the prevalence of thyroid nodules and carcinomas were 50.7% and 7.8%, respectively. Nodules were predicted by thyroid volume (OR = 1.030; 95% CI = 1.001–1.062). We found higher number of nodules in patients with thyroid carcinoma than in those with benign nodules (3 versus 2; ). Patients with Hashimoto’s thyroiditis presented nodules more frequently than patients with Graves’ disease (50.65% versus 27.28%; ), while the prevalence of carcinoma was similar (). Conclusions. Larger goiter was associated with carcinoma in Graves’ disease and Hashimoto’s thyroiditis. Younger patients presented higher risk of papillary thyroid carcinoma in Graves’ disease. The prevalence of carcinoma was similar in both conditions.
