Purpose.To investigate the effects of Corbrin Capsule (CS-C-Q80), a drug derived fromCordyceps sinensis(Berk.) Sacc., on autoimmune thyroid diseases (AITD).Methods.44 Patients with Graves’s disease (GD) and 56 patients with Hashimoto’s thyroiditis (HT) were randomly assigned to treatment group (GD-Tx and HT-Tx) or control group (GD-Ct and HT-Ct). The control groups were given methimazole or levothyroxine only while the treatment groups were given Corbrin Capsule (2.0 g tid) besides the same conventional prescriptions as control groups. Thyroid hormones, thyroid antibodies, and T lymphocyte subsets were quantified at baseline and 24 weeks posttreatment.Results.Significant drop of serum anti-TPO-Ab levels was observed in both GD-Tx and HT-Tx groups. Before treatment, GD patients had higher helper T cells compared to cytotoxic T cells, while HT patients suffered from a nearly inverted proportion of helper T/cytotoxic T cells. There was a significant drop of the helper T/cytotoxic T cells ratio in GD-Tx to the median of the normal ranges after Corbrin treatment for 24 weeks, while that in HT-Tx was elevated.Conclusion.Corbrin Capsule could restore the balance between helper T and cytotoxic T cells in both GD and HT patients with dual-directional immunomodulatory effects. And it could significantly reduce the autoantibody levels in both GD and HT.

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.

Abstract Background Zinc transporter 8 autoantibodies (ZnT8Abs) together with glutamic acid decarboxylase autoantibodies (GADAbs), insulinoma antigen 2 autoantibodies (IA-2Abs) and insulin autoantibodies (IAbs) are markers of type 1 diabetes mellitus (T1DM). We studied the prevalence of ZnT8Ab in children with autoimmune thyroid diseases (AITDs) to assess the association of AITDs and T1DM at the serological level. Methods The study groups consisted of 44 children with Graves’ disease (GD), 65 children with Hashimoto’s thyroiditis (HT), 199 children with T1DM with or without AITDs and 58 control children. ZnT8Ab, GADAb, IA-2Ab, IAb, 21-hydroxylase autoantibodies (21-OHAbs) and acetylcholine receptor autoantibodies (AChRAbs) were measured. Results ZnT8Abs were found in 4/44 (9.1%) patients with GD, and 4/44 (9.1%) patients with GD were positive for GADAb. Of the 65 HT patients, six (9.2%) were positive for ZnT8Ab, while four (6.2%) were positive for GADAb. In the T1DM group, 128/199 (64%) of the patients were positive for ZnT8Ab, 133/199 (67%) for GADAb and 109/199 (55%) for IA-2Ab. One GD patient and one HT patient were positive for all the four diabetes-associated autoantibodies. Two HT patients were positive for three diabetes autoantibodies. Two GD (4.5%) and five HT (7.7%) patients were positive for 21-OHAb only. None of the patients had AChRAb. In the control group, 2/58 (3.4%) were positive for GADAb and 2/58 (3.4%) were positive for ZnT8Ab. Conclusions Diabetes-associated autoantibodies including ZnT8Ab were found in children and adolescents with GD and HT.

Abstract. We investigated the percentage of circulating HLA-DR antigen positive (Ia antigen positive: Ia+) T cells and the additive proliferation by non-specific mitogens and thyroid-specific antigens by means of a cytotoxicity test in autoimmune thyroid diseases. Furthermore, we studied the stimulative function of circulating Ia+T cells in autologous mixed lymphocyte reactions. %Ia+T cells were significantly increased in patients with autoimmune thyroid diseases compared with those in normal controls. They were additionally increased by the stimulation of TSH-receptor or thyroid-microsome in patients with Graves' disease, and by the stimulation of thyroglobulin and thyroid-microsome in patients with Hashimoto's thyroiditis. As to the cellular immune function, circulating Ia+T cells stimulated Ia− T cells in autologous MLR in patients with autoimmune thyroid diseases. These data suggest that some of the T cells are already activated in vivo, that the activation of T cells may be by thyroid-specific antigens, and that these activated (Ia+) T cells may be able sequentially to induce the activation of inactivated (Ia−) T cells in autoimmune thyroid diseases.

Aims: To clarify the imbalance of Th17/Treg in different subtypes of autoimmune thyroid diseases (AITDs) including Graves' disease(GD), Hashimoto's thyroiditis(HT) and Graves' ophthalmopathy (GO). Methods: 47 patients with AITD (including 16 GD, 15 HT, and 16 GO) and 12 healthy controls were enrolled in this study. The percentages of Th17 and Treg cells, the ratio of Th17/Treg, as well as their related transcription factors RORγt and Foxp3 mRNA in peripheral blood mononuclear cells (PBMCs) were measured by flow cytometry and real-time quantitative PCR Results: Compared with those in control group, the percentage of CD4+IL-17+T cell(Th17) and the mRNA expression of its transcription factor RORγt were higher in PBMCs of AITDs (P<0.05), particularly in HT subgroup (P<0.01). The percentage of CD4+Foxp3+T (Treg) cells and its transcription factor Foxp3 mRNA were significantly decreased in PBMCs of GD (P<0.05). In addition, the ratio of Th17/Treg was elevated in AITD group and GO subgroup (P<0.01). In GO subgroup, the patients with clinical activity score (CAS) above 4.5 had higher percentages of Th17 than those with CAS ranging from 3 to 4.5 (P<0.05). Conclusion: Increased Th17 lymphocytes may play a more important role in the pathogenesis of HT and GO while decreased Treg may be greatly involved in GD.

Thyroid disorders are one of the most frequent disorders affecting endocrine system. The present study aimed to identify the frequency of thyroid disorder in our locality at Duhok city. To do so, a total of one hundred patients and one hundred apparently healthy control individuals were enrolled in this study. Samples of venous blood (5 ml) were withdrawn from patients and control subjects and analysed. Clinical assessment was performed by a specialist and each patient provided with a document supporting preliminary clinical diagnosis. Measurements of serum TSH, T3, T4, and anti-thyroperoxidase antibodies (anti-TPO antibodies) serum levels were performed. All assays were conducted at Duhok central health laboratory. Out of the one hundred patients and the one hundred control groups, forty-two and thirty candidates were randomly selected, respectively. The mean TSH serum levels of 25.87 (uIU/ml) for the patients significantly differ from that of the control group 3.55 (uIU/ml) (p<0.001). However, T3 and T4 serum levels indicated no significant difference between the two categories. Moreover, there was statisticaly significant difference (p< 0.0001) between the patients and control groups when their mean serum anti-TPO concentrations were compared.  In conclusion, considerable number of subjects appeared to be candidates for deranged thyroid functions and is susceptible to autoimmune thyroid disorder.
