Acupuncture treatment for Hashimoto's thyroiditis: An exploratory randomized controlled trial.

Background: Hashimoto's thyroiditis (HT) has a high incidence rate and unresolved clinical symptoms. Although Hand Yangming Meridian Penetrating Acupuncture has been used to treat thyroid diseases in China, there is no randomized controlled trial (RCT) on HT. Methods: This exploratory RCT aims to preliminarily evaluate the efficacy, safety, and feasibility of Hand Yangming Meridian Penetrating Acupuncture in the treatment of HT. Included subjects were randomly assigned to the acupuncture group and the waiting treatment group at a ratio of 1:1. Subjects in the acupuncture group received 16 weeks of acupuncture treatment, followed by a 16-week follow-up observation phase. Subjects in the waiting group received thyroxine supplementation for 16 weeks, followed by 16 weeks of compensation treatment. Serum thyroid peroxidase antibody (TPOab) and thyroglobulin antibody (TGab) levels were the main indicators, and Thyroid-Related Patient-Reported Outcome short form (ThyPRO-39), MOS Item Short Form Health Survey (SF-36), and Hospital Anxiety and Depression Scale (HADS) scores were also recorded. Results: In total, 58 subjects were included. After 16 weeks of treatment, there was no statistical difference in the changes in TPOab levels between the two groups, but the TGab level in the acupuncture group was significantly lower than in the waiting group (difference: -141.97 [95 % CI: -222.4 to -61.5], P = 0.011). Moreover, the total ThyPRO-39 and SF-36 scores were statistically different between the two groups (PThyPRO-39 < 0.001, PSF-36 = 0.005). There was no statistical difference in HADS between the two groups. Conclusions: Hand Yangming Meridian Penetrating Acupuncture may be safe and feasible for HT hypothyroidism to improve symptoms and reduce TGab levels. Trial registration number: This trial was registered at Acupuncture-Moxibustion Clinical Trial Registry: AMCTR-IOR-19000308 (ChiCTR1900026830, https://www.chictr.org.cn/searchprojEN.html).

Investigating the effect of combined use of selenium and Myo-inositol supplements on thyroid function and autoimmune characteristics in thyroid disorders: a systematic review and meta-analysis.

BACKGROUND: This study aimed to systematically review the effect of selenium and inositol combination on thyroid function, autoimmune characteristics in thyroid diseases. RESEARCH DESIGN AND METHODS: To identify eligible studies, a systematic search was conducted in the PubMed/MEDLINE, Science-Direct, CINHAL, EMBASE, SCOPUS, Psychinfo, Cochrane, ProQuest, and Web of Science were searched using the main concepts, and all English-written articles that were published between 2007 and 2022 and had an available full text were examined. RESULTS: The data analysis of this research revealed that after the simultaneous use of selenium and inositol supplements, the level of Triiodothyronine(T3) increased by 0.105 in patients with thyroid disorders although this increase was not significant (P-value: 0.228). The level of Thyroxine (T4) significantly increased by 0.06 (P-value: 0.04). Anti-Thyroid Peroxidase Antibody (TPOAb) titer decreased by 119.36%, which was not significant (P-value: 0.070). Finally, the level of Thyroid-stimulating hormone (TSH) decreased by 1.45%, which was a significant change (P-value: 0.001). CONCLUSION: It was observed that simultaneous use of selenium and inositol supplements did not change the T3 and TPOAb titer levels; however, it leads to a decrease in TSH and increase in T4 levels. Further studies are required due to the limited number of studies.

Therapeutic effect of vitamin D in Hashimoto's thyroiditis: a prospective, randomized and controlled clinical trial in China.

BACKGROUND: The study aims to explore the clinical effects of Vitamin D (VitD) supplements for Hashimoto's Thyroiditis (HT), which are unclear according to other studies. METHODS: Female patients with newly diagnosed HT from January to June in 2018 were included. This study is registered in the Chinese Clinical Trials Registry with registration number ChiCTR1800014619 (URL: https://www.chictr.org.cn/). Patients were randomly assigned to the treatment group and the control group. The treated group were further randomly assigned to a VitD supplement group or VitD & Levothyroxine (L-T4) supplement group. After 6 months, we recorded and compared various indicators between different groups. RESULTS: A total of 179 patients, aged 12 to 75, were used for statistical analysis. A significant decrease in Thyroid Peroxidase Antibody (TPOAb) level was observed (351.70±183.25 vs. 246.37±157.39, P<0.001) in the VitD-treated group compared to the control group after 6 months. Free Triiodothyronine (FT3) and Free Thyroxine (FT4) level were increased (FT3: 4.30±0.64 vs. 4.84±0.9, P<0.001; FT4: 15.15±1.93 vs. 17.38±2.97, P<0.001), and Thyroid-Stimulating Hormone (THS) level was decreased (3.58±1.78 vs. 2.25±1.22, P<0.001) in the VitD-treated group compared to the control group. CONCLUSION: VitD supplementation can effectively slow progression of hypothyroidism, improve thyroid function, and reduce the anti-thyroid antibody level. This suggests it is useful for HT.

Outcomes of laser-induced thermotherapy for thyroid nodules at the West Vascular Center, Ukraine.

Thyroid nodules are common, occurring in 50-60% of healthy patients. Currently, there are no effective conservative treatment options for nodular goiter, and surgery can have limitations and potential complications. The purpose of this study was to evaluate the efficacy, tolerability, and long-term results of using sclerotherapy and laser-induced interstitial thermotherapy (LITT) to treat benign thyroid nodules. A retrospective analysis was conducted on 456 patients with benign nodular goiter who received LITT. The volume of the nodular goiter was measured at 1, 3, 6, and 12 months post-treatment, and a repeated fine needle aspiration (FNA) with the cytological examination was performed to verify the structure of the nodular goiter in the long term. The results showed that LITT was an effective method for treating nodular mass (nodules), as evidenced by a decrease in the volume of NG by 51-85% after 6-12 months. FNA results 2-3 years after LITT showed no thyrocytes, only connective tissue, indicating the efficacy of LITT for benign thyroid nodules. LITT is highly effective in most cases, often resulting in the disappearance or significant decrease in nodular formations.

The association between dietary selenium intake and Hashimoto's thyroiditis among US adults: National Health and Nutrition Examination Survey (NHANES), 2007-2012.

BACKGROUND: Selenium has been shown to influence the pathological processes and physiological functions of thyroid. Although growing evidence has shown that selenium can improve the treatment of Hashimoto's thyroiditis (HT), there is a need to evaluate the association between dietary selenium intake and HT in a large cross-sectional study. This study explored the association between dietary selenium intake and HT based on the National Health reand Nutrition Examination Survey (NHANES) database (2007-2012). METHODS: A total of 8756 of 30,442 participants were included in the study. Dietary selenium intake was the independent variable, while HT was the dependent variable. In addition, the relative importance of the selected variables was determined using the XGBoost model. A smooth curve was constructed based on the fully adjusted model to investigate the potential linear relationship between dietary selenium intake and HT. Smooth curves were also constructed to explore the linear/non-linear relationship between dietary selenium intake and thyroid peroxidase antibody (TPOAb)/ thyroglobulin antibody (TgAb). RESULTS: The mean age of the enrolled participants was 44.35 years (± 20.92). The risk of HT was significantly reduced by a 35% per-unit increase in dietary selenium intake after fully adjusting for covariates according to the model (log2-transformed data; OR 0.65; 95% CI 0.51, 0.83). The XGBoost model revealed that dietary selenium intake was the most important variable associated with Hashimoto's thyroiditis. Dietary selenium intake (Log2-transformed) was negatively correlated with TPOAb levels [- 16.42 (- 22.18, - 10.65), P < 0.0001], while a non-linear relationship was observed between dietary selenium intake and TgAb with an inflection point of 6.58 (95.67 µg, Log2-transformed). CONCLUSION: Dietary selenium intake is independently and inversely associated with HT risk. Moreover, dietary selenium intake is negatively correlated with TPOAb levels and non-linearly correlated with TGAb levels. Therefore, dietary selenium intake may be a safe and low-cost alternative for the prevention and treatment of HT.

A Multiplex Thyroid-Specific Assay for Quantification of Circulating Thyroid Cell-Free RNA in Plasma of Thyroid Cancer Patients.

BACKGROUND: The standard of care for thyroid cancer management is thyroidectomy and adjuvant radioactive iodine (RAI). There is a paucity of clinical tool that quantifies residual thyroid volume reliably for precise adjuvant RAI dosing. Serum thyroglobulin (TG), tumour marker for thyroid cancer, takes 4 weeks for complete clearance due to its long half-life, and might be undetectable in 12% of structural disease patients. It detects recurrence with a sensitivity of 19-40%, mainly attributed to issue of TG antibody interference with TG immunometric assay. We hypothesise that the quantity of thyroid-specific cell-free RNA (cfRNA) is indicative of amount of thyroid tissues, and that during thyroid surgery, cfRNA levels decrease accordingly. METHODS: We identified 11 biologically significant and highly expressed thyroid-specific targets from Human Protein Atlas and literature. To assess for a fall in thyroid-specific cfRNA level, we recruited 16 patients undergoing thyroid surgery or RAI for malignant or benign thyroid disease, and tracked longitudinal trend of cfRNA. To assess the utility of cfRNA in detecting metastatic thyroid cancer, cfRNA of 11 patients at intermediate to high risk of recurrence was measured during surveillance and at time of clinical recurrence. RESULTS: The multiplex assay was capable of amplifying and quantifying multiple thyroid-specific genes in a single reaction. The selected targets were amplified successfully from RNA extracted directly from the thyroid (positive control), indicating that they were highly expressed within thyroid tissue. These cfRNAs were present in plasma, in amounts quantifiable using qRT-PCR. Four cfRNA transcripts (TPO, GFRA2, IVD, TG) fell post-treatment in more than 50% of cohort. The thyroid peroxidase (TPO) cfRNA fell post-therapy in 63% of cohort by 80%, as early as 1 day post-treatment, supporting the potential role as early indicator of remnant thyroid tissue volume. We demonstrated the clinical relevance of circulating TPO cfRNA by tracking temporal changes in setting of peri-treatment, recurrence, and TG Ab positive state. CONCLUSION: Using a multiplex pre-amplification approach, the TPO cfRNA was a potential biomarker that can track residual thyroid mass. It can be further optimised for quantification of thyroid volume to guide RAI doses and for detection of thyroid cancer recurrence.

The effects of selenium supplementation on antibody titres in patients with Hashimoto's thyroiditis.

INTRODUCTION: The objective of this study was to evaluate the effect of selenium supplementation on autoantibody titres, thyroid ultrasonography, and thyroid function in patients with Hashimoto's thyroiditis (autoimmune thyroiditis) and normal thyroid reference range. MATERIAL AND METHODS: A total of 100 patients were given 200 ug/d selenium yeast orally, their thyroid function, levels of serum selenium, thyroid peroxidase antibodies (TPOAb), thyroglobulin antibodies (TGAb), and urine iodine were measured, and thyroid ultrasonography was performed before administration and three and six months afterwards, and the data were statistically analysed. RESULTS: The subjects exhibited a selenium deficiency before the administration of selenium, and the serum levels increased to moderate levels three and six months after the selenium supplementation (p < 0.05). The titres of TGAb decreased significantly in patients after six months of selenium supplementation (p < 0.05). In the high antibody group, TgAb decreased after 6 months compared with baseline (p = p < 0.05), and TPOAb decreased after 3 and 6 months of selenium supplementation compared with baseline (p < 0.05). CONCLUSION: In patients with autoimmune thyroiditis and normal thyroid reference range, there was a general selenium deficiency, but after six months of treatment it was shown that selenium supplementation may be effective in reducing the titres of TGAb and TPOAb.

The relationship between iodine nutrition and thyroid disease in lactating women with different iodine intakes.

Areas with low, adequate and excessive I content in water co-exist in China. Limited data are currently available on I nutrition and thyroid disease in lactating women and their breast-fed infants with different I intakes. This study aimed to evaluate I nutrition in both lactating women and their infants and the prevalence of thyroid disease in areas with different levels of I in water. From January to June 2014, a total of 343 healthy lactating women (excluding those taking anti-thyroid drugs or I supplements within a year of the study, consuming seafood at the time of the study or those diagnosed with congenital thyroid disease) from Beihai in Guangxi province and Jiajiazhuang, Yangcheng, Jicun and Pingyao townships in Shanxi province were selected. Compared with the I-sufficient group, median urinary I concentrations in both lactating women and infants as well as breast milk I levels were significantly lower in the I-deficient group (P<0·001). The prevalence of thyroid disease in lactating women, particularly subclinical hypothyroidism, was higher in the I-excess group than in the I-sufficient group (P<0·05). In areas with excessive water I content, high thyroid peroxidase antibody and high thyroglobulin levels were risk factors for abnormal thyroid-stimulating hormone levels. Our data collectively suggest that excessive I intake potentially causes subclinical hypothyroidism in lactating women. Moreover, enhanced monitoring of I status is important to avoid adverse effects of I deficiency or excess, particularly in susceptible populations such as pregnant or lactating women and infants.

Efficacy of Indigo Naturalis Topical Treatment of Hashimoto’s Thyroiditis and Its Effects on Serum TGAb and TPOAb / 中国中医药信息杂志

Objective To observe the efficacy of topical indigo naturalis on the serum thyroglobulin antibody (TGAb) and thyroid peroxidase antibody (TPOAb) in Hashimoto's thyroiditis (HT). Methods Sixty-five cases of HT were randomly divided into the treatment group (33 cases) and the control group (32 cases). Hyperthyroidism patients and hypothyroidism patients in the two groups were treated with methimazole 10 mg/d and levothyrocine 25-50 μg/d to control their thyroid function. Based on the basic treatment, patients in the treatment group were treated with topical indigo naturalis local external application, which lasted for 6 months. Results TCM clinical symptoms were improved in both two groups, with statistical significance between the two groups (P<0.05, P<0.01). The efficacy of TCM clinical symptoms was 81.82% (27/33) in the treatment group and 65.63% (21/32) in the control group, with statistical significance (P<0.01). The total effective rate of the treatment group was 84.85% (28/33) and the control group was 71.88%(23/32), with statistical significance between the two groups (P<0.05). Compared with that before treatment, the levels of TGAb and TPOAb were lower in both groups (P<0.05), and with statistical significance between the two groups (P<0.01). Conclusion Indigo naturalis can improve efficacy of treatment for HT, and effectively reduce autoimmune antibodies indicators of thyroid.
