cholecalciferol and Hashimoto-Disease

The 100th anniversary of the discovery of vitamin D3 (VitD3) coincides with significant recent advances in understanding its mechanism of action along with accumulating knowledge concerning its genomic and nongenomic activities. A close relationship between VitD3 and the immune system, including both types of immunity, innate and adaptive, has been newly identified, while low levels of VitD3 have been implicated in the development of autoimmune thyroiditis (AIT).

Hashimoto's thyroiditis (HT) is the most prevalent autoimmune thyroid disease (ATD) worldwide and is strongly associated with miscarriage and even recurrent miscarriage (RM). Moreover, with a deepening understanding, emerging evidence has shown that immune dysfunctions caused by HT conditions, including imbalanced subsets of CD4+ T-helper cells, B regulatory (Breg) cells, high expression levels of CD56dim natural killer (NK) cells, and cytokines, possibly play an important role in impairing maternal tolerance to the fetus. In recent years, unprecedented progress has been made in recognizing the specific changes in immune cells and molecules in patients with HT, which will be helpful in exploring the mechanism of HT-related miscarriage. Based on these findings, research investigating some potentially more effective treatments, such as selenium (Se), vitamin D3, and intravenous immunoglobulin (IVIG), has been well developed over the past few years. In this review, we highlight some of the latest advances in the possible immunological pathogenesis of HT-related miscarriage and focus on the efficacies of treatments that have been widely introduced to clinical trials or practice described in the most recent literature.

A Prospective Study to Evaluate the Possible Role of Cholecalciferol Supplementation on Autoimmunity in Hashimoto's Thyroiditis Biva Bhakat1 , Jyotirmoy Pal2 , Sukdeb Das3 , Sumit Kr Charaborty4 1,3Nil Ratan Sircar Medical College, Kolkata, 2 RG Kar Medical College and Hospital, 4 North Bengal Medical College, Siliguri Introduction: Hashimoto thyroiditis (HT) is an autoimmune disease that destroys thyroid cells by antibody and call-mediated immune processes. Hashimoto thyroiditis is the commonest cause of goitre in iodine-sufficient regions.[1] The aetiology of Hashimoto disease is very poorly understood. Most patients develop antibodies to a variety of thyroid antigens, the most common of which is anti-thyroid peroxidase (anti-TPO). Many also form antithyroglobulin (anti-Tg) and TSH receptor blocking antibodies (TBII). These antibodies attack the thyroid tissue, eventually leading to inadequate production of thyroid hormone. There is a small subset of the population, around 10-15% with the clinically evident disease, that are serum antibody-negative.[2][3] The mechanisms underlying the assumption that vitamin D is linked with autoimmunity are not clear but probably are associated with its anti-inflammatory and immunomodulatory functions. The dendritic cells are antigen-presenting cells originating from bone marrow and also a primary target for the immunomodulatory activity of vitamin D. 1,25[OH]2D has direct immunomodulatory effects at the level of the T cell vitamin D receptor. Together, these immunomodulatory effects can lead to the protection of target tissues, such as thyroid cells in autoimmune diseases. Considering that in HT, a disorder of T cell-mediated immunity, immunologic attack is triggered when thyrocytes express MHC class II surface HLA-DR antigens, a process induced by the production of Th1 type inflammatory cytokines (especially IFN-γ). Moreover, at another stage, after being activated by T cells, B cells' ongoing proliferation might be inhibited and apoptosis might be induced by 1,25[OH]2D. Thus, 1,25[OH]2D might decrease antibodies that react with thyroid antigens. The exact levels of vitamin D that are sufficient to improve the immune regulatory function and lead to an effective immune response, should be investigated. Several clinical studies have reported a low vitamin D status in AITD or HT, indicating an association between vitamin D deficiency and thyroid autoimmunity. If supplementation of the Vitamin D decreased thyroid an. Most studies have shown an association between low vitamin D status and pathogenesis of AITD, especially HT. However, there are only few preliminary interventional studies for HT. whether vitamin D supplementation is beneficial for AITD or HT, should be evaluated. Treatment of HT mainly based on thyroid hormone supplementation, so if a beneficial role of vitamin D supplementation is identified/ confirmed, it will be helpful in the treatment of patients with HT and may be a part of treatment of HT patients.. Evaluating the role of vitamin D on an excessive thyroid immune response.. Study area: N.R.S. Medical college and hospital, Kolkata (Department of General Medicine).. 1 year (January,2019 to December,2019 Sample size: 100 patients both male and female. Sample Design: Patients attending outpatient dept in N.R.S medical college.. Prospective, hospital based, single centre study.. Newly diagnosed patients (age >18 years and of both sexes) with HT and vitamin D deficiency.. Patients suffering from: Other autoimmune diseases. Chronic illnesses like diabetes mellitus, chronic kidney disease, chronic liver disease, malignancy. Pregnancy Study tools: Estimation from serum: TSH. Free thyroxine (FT4) 25 hydroxy vitamin D Anti-thyroid peroxidase (anti-TPO) antibody' Study techniques: This is a prospective study conducted in N.R.S Medical college, Kolkata, India. Total 100 adult patients of both sexes diagnosed with HT and vitamin D deficiency (vit D<30 ng/ml)12, having none of the exclusion criteria and getting treatment on out-patient department basis, who gave informed consent were included in our study. Blood samples drawn for anti TPO antibody and 25hydroxy vitamin D from all the participants. The correlations between serum Vit D and anti TPO antibody were measured and presented by correlation coef ficient (r2). Study participants are randomly assigned into two groups by random permuted block. Cholecalciferol supplement given in the dose of 60,000 IU weekly for 8 weeks in one group (n = 50). Another group (n = 50) were given placebo (empty soft gelatine capsule). At the onset of the study, patients were requested to keep their habitual diet and routine level of physical activity throughout the study period and not to take any medication that might affect their reproductive physiology. Compliance to the consumption of supplement and placebo was examined by empty blister packets. However, 2 patients from cholecalciferol group and 1 patient from control group lost to follow up. After 8 weeks blood anti TPO antibody level measured in both the groups (n = 48 & 49 in 2 group). The change in the mean value of anti TPO antibody measured and statistical significance of the change checked. Results considered significant or non-significant when P> or < 0.05, respectively. TSH, T4 measurement Performed with chemiluminescence using ADVIA Centaur XP Immunoassay System. Work plan: Study was done over 12 months. Data collected and compilation done and then statistical analysis done by standard statistical method.. For statistical analysis data were entered into a Microsoft excel spreadsheet and then analyzed by SPSS (version 27.0; SPSS Inc., Chicago, IL, USA) and GraphPad Prism version 5. p-value ≤ 0.05 was considered for statistically significant. The Negative Correlation was found between Serum 25 hydroxy vitamin D (ng/ml) vs Serum TSH (mU/L) which was statistically significant. Distribution of mean serum anti-TPO antibody level (IU/ml) [mean±SD] in both groups before and after intervention Reduction of serum anti-TPO antibody level in cholecalciferol group is 30.5% and reduction of serum anti-TPO antibody level in placebo group is 16.5%.. This study is carried out with the total no. of 100 outdoor based patients of diagnosed Hashimoto's Thyroiditis (elevated Anti-thyroid peroxidase antibody) and vitamin D deficiency (vit D < 30 ng/mL)12 in Nil Ratan Sircar medical college and hospital within the mentioned study period. The study focussed on evaluating the role of vitamin D on an excessive thyroid immune response i.e. the effect of vitamin D supplementation on thyroid autoimmunity and that low vitamin D levels and the risk of HT are closely associated and the potential application of vitamin D in the treatment of AITD. The result demonstrates a negative Correlation between Serum 25 hydroxy vitamin D (ng/mL) vs anti TPO antibody (IU/ml) which was statistically significant. Pearson Correlation Coefficient (r)= -0.775, p value = 0.0001. Goswami et al. conducted a community-based survey on 642 adults to investigate the relationship between serum vitamin D concentrations and thyroid autoimmunity. Their results highlighted a significant inverse association between 25(OH)D3 and TPO Ab levels [40]. This inverse correlation was substantiated in the following studies.[5-8] As regards thyroid function in the context of HT, Mackawy and co-workers demonstrated a strong negative association between serum vitamin D concentrations and TSH levels, leading to speculate that vitamin D deficiency in HT patients could be associated with a progression towards hypothyroidism (TSH > 5.0 m UI/L) [45]. Our study also demonstrates negative Correlation between Serum 25 hydroxy vitamin D (ng/mL) vs Serum TSH (mU/L) and the result was statistically significant. Pearson Correlation Coefficient (r) = -0.301, p value = 0.003. So, the results indicate that vitamin D deficiency is a risk factor of Hashimoto's thyroiditis. Mean (mean± s.d.) Serum anti TPO antibody (IU/ml) before intervention was 545.06± 230.82 and after cholecalciferol supplementation the mean value decreased to 378.6± 160.49. So, there is a 30.5% reduction in the mean value of anti TPO antibody level. Difference of mean Serum anti TPO antibody (IU/mL) was statistically significant (p < 0.0001). In the placebo group the mean Serum anti TPO antibody (IU/ml) (mean ± s.d.) of patients was 686.97± 290.19 and after 8 weeks of placebo the mean value was 573.1 ± 254.09. So, in the placebo group the reduction is only 16.5%. Difference of mean Serum anti TPO antibody (IU/ml) was statistically significant (p < 0.0001). Therefore, in line with the hypothesis. The 8 weeks randomized; double-blind, placebo-controlled clinical trial demonstrates a negative correlation between Serum 25 hydroxy vitamin D vs anti TPO antibody level. Treatment with 60,000 IU cholecalciferol weekly for 8 weeks, is associated with significant decrease in antithyroid antibody titers. It also improved serum TSH level compared with the placebo, i.e. supplementary treatment with cholecalciferol seems to have beneficial effects on AITD. However, large multicentre studies are needed to investigate the impact of vitamin D supplementary treatment on meaningful long-term clinical end points in AITD. References Dana L.

Hashimoto's thyroiditis (HT) results from chemoattraction of inflammatory cells toward the thyroid gland by inducing the production of interferon-gamma (IFNγ)-induced protein 10 (IP10) by T helper (Th) 1 cells. Vitamin D may suppress the IFNγ-IP10 axis, but this new function of vitamin D has not yet been investigated in HT patients. In an intervention and control group, patients received 50000 IU cholecalciferol or placebo every week for three months, respectively. The CD4+ T cells of 40 patients were isolated, and the mRNA expression levels of vitamin D receptor (VDR), peroxisome proliferator-activated receptors (PPAR)-α, and PPAR-γ genes were determined by real-time PCR. ELISA method was used to determine serum levels of vitamin D, tumor necrosis factor-alpha (TNF-α), IFN-γ, and IP10. Vitamin D levels in the intervention group were significantly higher than in the placebo group after supplementation. PPAR-α and PPAR-γ gene expression levels did not differ significantly between the two groups. The serum levels of IP10, IFNγ, and TNF-α decreased significantly in the vitamin D group, as well as in the placebo group.  During this study, vitamin D levels significantly increased in the intervention group and inflammatory factors decreased. Based on the similar results obtained in the placebo group, further studies with larger sample sizes and longer intervention times are recommended.

Autoimmune (Hashimoto's thyroiditis) is characterized by a strong female preponderance, which may suggest that sex hormones have an impact on thyroid autoimmunity. The aim of this study was to investigate whether testosterone determines vitamin D action on thyroid antibody titers and thyroid function tests in men with autoimmune thyroiditis and low testosterone levels.. The study included 36 men with testosterone deficiency, 17 of whom had been treated for at least 26 weeks with oral testosterone undecanoate (120 mg daily). Because of coexistent euthyroid Hashimoto's thyroiditis, all participants were then treated with vitamin D (100 μg daily). Serum titers of thyroid peroxidase and thyroglobulin antibodies, serum levels of thyrotropin, free thyroid hormones, testosterone and 25-hydroxyvitamin D, as well as Jostel's thyrotropin index, SPINA-GT and SPINA-GD were assessed before vitamin D treatment and 26 weeks later.. With the exception of testosterone levels, there were no significant differences between both study groups in serum hormone levels, antibody titers and thyroid function tests. All participants completed the study. In addition to increasing 25-hydroxyvitamin D levels, vitamin D increased SPINA-GT and reduced thyroid peroxidase and thyroglobulin antibody titers. In testosterone-treated men, vitamin D increased testosterone levels. Vitamin D did not affect serum levels of thyrotropin, free thyroid hormones, Jostel's thyrotropin index and SPINA-GD. Treatment-induced changes in thyroid antibody titers and SPINA-GT were more pronounced in testosterone-treated than testosterone-naïve men.. The obtained results suggest that the beneficial effect on thyroid autoimmunity and thyroid secretory function is stronger in men receiving testosterone therapy.

The classic role of vitamin D is its effect on calcium and phosphate homeostasis. The subject of interest in recent years has been its non-calcemic impact on neoplastic processes and the immune system. The aim of the study was to assess 25(OH)D3 concentrations in patients treated for papillary thyroid carcinoma (PTC) and Hashimoto's thyroiditis (HT).. The study included 80 patients aged 19-83 years (average age 52.96 years) treated between 2000-2011 in Swietokrzyskie Centrum Onkologii. The analysis was conducted in two groups of patients: a PTC group of 40 women aged 19 to 83 years (average age 50.40 years) and a HT group of 40 women aged 30 to 75 years (average age 55.73 years). The group of PTC patients was further divided into two subgroups: 19 patients with micro. carcinoma (T1a) and 21 patients with a higher grade of cancer (>T1a). A group of patients with HT comprised women treated with subsitutive doses of L-thyroxine for hypothyroidism. The serum concentration of 25(OH)D3 was compared in both groups: PTC vs. HT. Among patients with PTC serum 25(OH)D3 was analysed depending on the concentration of TSH: TSH< or = 0.1 microlU/ml vs. TSH> 0.1 microlU/ml, and depending on the stage of cancer: Tla vs.> T1a.. There were no differences in the prevalence of hypovitaminosis and vitamin D deficiency in both groups (65% of patients with PTC vs. 62.5% with HT). In the PTC group no statistically significant differences in serum 25(OH)3, depending on the con. centration of TSH and cancer clinical stage, were found.. This study showed no difference in concentrations of 25(OH)D3 in patients with papillary thyroid cancer and Hashimoto's thy. roiditis. Patients with PTC showed no relationship between serum 25(OH)D3 and clinical stage of the disease or TSH.level.
