\"Dr. Izabella Wentz, the author of the phenomenal New York Times bestseller Hashimoto's Thyroiditis, returns with a long-awaited, groundbreaking prescription to reverse the symptoms of this serious autoimmune condition that is becoming one of the country's fastest growing diseases. More than thirty-five million Americans currently suffer from Hashimoto's--an autoimmune disease that affects the thyroid gland and causes the body to attack its own cells. To alleviate the symptoms of this debilitating condition--including chronic cough, acid reflux, IBS, allergies, chronic pain, hair loss, brain fog, and forgetfulness--patients are often prescribed synthetic hormones that have numerous life-altering side effects. But there is a better way. Diagnosed with Hashimoto's at twenty-seven, pharmacist Dr. Izabella Wentz knows first-hand the effects of the disease, as well as the value--and limitations--of medication. The key to improved health, she argues, involves lifestyle interventions. In Hashimoto's Protocol, she outlines a proven treatment that has helped thousands heal and many others feel better--in as fast as ninety days. Drawing on her own personal experience as well as her work consulting with thousands of patients, Hashimoto's Protocol offers a practical pathway for healing and reversing the autoimmune damage at the root of the disease. The first step is a quick-start two-week detox that includes foods to eat and inflammatory foods to avoid, advice on supplements to support the liver, and an adrenal recovery plan. Next, readers create a personalized plan with foods, supplements, and other lifestyle interventions tailored to their body's own unique Hashimoto's triggers, which they can identify using self-tests included in the book. Hashimoto's Protocol also features original recipes. Grounded in the latest science, Hashimoto's Protocol is the first book to offer a proven protocol by an acknowledged expert in the field to treat this condition without dangerous hormones--and help sufferers reclaim their lives\"-- Provided by publisher.

Background Patients with chronic autoimmune thyroiditis have impaired health-related quality of life. The thyroid gland has a high selenium concentration, and specific selenoprotein enzyme families are crucial to immune function, and catalyze thyroid hormone metabolism and redox processes in thyroid cells. Previous randomized controlled trials have found that selenium supplementation decreases thyroid-disease-specific antibody levels. We hypothesize that selenium might be beneficial in the treatment of chronic autoimmune thyroiditis. Methods/Design The CATALYST trial is an investigator-initiated randomized, blinded, multicentre clinical trial of selenium supplementation versus placebo in patients with chronic autoimmune thyroiditis. Inclusion criteria: age ≥18 years; serum thyroid peroxidase antibody level ≥100 IU/ml within the previous 12 months; treatment with levothyroxine and written informed consent. Exclusion criteria: previous diagnosis of toxic nodular goitre, Graves’ hyperthyroidism, postpartum thyroiditis, Graves’ orbitopathy; previous antithyroid drug treatment, radioiodine therapy or thyroid surgery; immune-modulatory or other medication affecting thyroid function; pregnancy, planned pregnancy or breastfeeding; allergy towards any intervention or placebo component; intake of selenium supplementation >55 μg/day; inability to read or understand Danish or lack of informed consent. The trial will include 2 × 236 participants. The experimental intervention and control groups will receive 200 μg selenium-enriched yeast or matching placebo tablets daily for 12 months. The experimental supplement will be SelenoPrecise ® . The primary outcome is thyroid-related quality of life assessed by the Thyroid Patient-Reported Outcome (ThyPRO) questionnaire. Secondary outcomes include serum thyroid peroxidase antibody concentration; serum triiodothyronine/thyroxine ratio; levothyroxine dosage; adverse reactions and serious adverse reactions and events. Discussion In this pragmatic trial, participating patients follow their usual treatment at their usual hospitals. In order to collect high-quality data on the clinical course and quality of life, and to minimize missing data, an elaborate trial management system has been designed. 12 months intervention duration was selected in consideration of the primary outcome, thyroid-related quality of life. Trial registration ClinicalTrials.gov ID: NCT02013479 .

Abstract Context Riedel thyroiditis (RT) is a rare inflammatory autoimmune disease that is often a clinically diagnostic dilemma because of its insidious presentation and nonspecific symptoms. Objective The aim of the present systematic review and meta-analysis is to clarify the presentation, management, and outcomes of RT. Study Selection A systematic search of PubMed/MEDLINE and Web of Science was conducted to identify relevant reports published up to September 2019. Data Extraction First author, country, patient sex, ethnicity, presentation, biochemical status, duration of symptoms, histology, treatment, follow-up duration, and short- and long-term outcomes. Data Synthesis Data from 212 RT patients were retrieved. The mean age was 47 years with a predominantly female population (81%). Neck swelling (89%), dyspnea (50%), and neck pain (41%) were the most common presenting symptoms. Inflammatory markers were elevated in 70% to 97% and thyroid antibody positivity was present in less than 50%. Up to 82% underwent surgical intervention, with the most common being total thyroidectomy in 34% of individuals. Glucocorticoids were used in 70% of individuals with median duration 3 months. Prognosis was reasonable with 90% having resolution or improvement of symptoms. Conclusions This analysis is the largest and most comprehensive to date of RT and provides clinicians with vital information on the common presentation features that may alert to the diagnosis and highlight management options.

Hypothyroidism is often diagnosed, and subsequently treated, due to health-related quality of life (HRQL) issues. However, HRQL following treatment has never previously been assessed in longitudinal descriptive studies using validated instruments. To investigate disease-specific (ThyPRO) and generic (SF-36) HRQL, following levothyroxine therapy in patients with hypothyroidism due to autoimmune thyroiditis. This prospective cohort study was set at endocrine outpatient clinics at two Danish university hospitals. Seventy-eight consecutive patients were enrolled and completed HRQL questionnaires before, six weeks, and six months after initiation of levothyroxine therapy. Normative ThyPRO (n = 739) and SF-36 (n = 6,638) data were available for comparison and changes in HRQL following treatment were estimated and quantified. Prior to treatment, all ThyPRO scales were significantly impacted (p<0.0001), compared to the general population sample. The same was observed for seven of eight SF-36 scales, the exception being Bodily Pain. Tiredness (ThyPRO) and Vitality (SF-36) were the most markedly impacted scales. After six weeks of treatment, nine of thirteen ThyPRO scales had significantly improved. ThyPRO improvements were consistent at six months, where five of eight SF-36 scales had also significantly improved, but deficits persisted for a subset of both ThyPRO and SF-36 scales. In this population of hypothyroid patients, HRQL was widely affected before treatment, with tiredness as the cardinal impairment according to both ThyPRO and SF-36. Many aspects of HRQL improved during the first six months of LT4 therapy, but full recovery was not obtained. Our results may help clinicians inform patients about expected clinical treatment effects.

Despite treatment with levothyroxine, hypothyroidism and autoimmune thyroiditis (AIT) may be associated with reduced quality of life (QoL), an enigmatic condition referred to as \"syndrome T\". Peripheral neuropathy, described in untreated thyroid disease, could be a contributing mechanism. We analysed autonomic and somatosensory function in 29 patients with AIT and treated hypothyroidism and 27 healthy volunteers. They underwent heart rate variability (HRV) analysis and quantitative sensory testing (n = 28), comprising 13 parameters of small and large nerve fibre function and pain thresholds. Autonomic cardiovascular function was assessed in rest, deep respiration and orthostasis. Additionally, biomarkers for autoimmunity and thyroid function were measured. Anxiety, depression and QoL were assessed using validated questionnaires. 36% of the patients showed at least one sign of somatosensory small or large fibre dysfunction. 57% presented with mild hyperalgesia to at least one stimulus. Several markers of autonomic function and some detection thresholds were related to the antibody titres. Anxiety, depression scores and QoL correlated to antibody titres and HRV measures. Autonomic and somatosensory dysfunction indicate that in treated hypothyroidism and AIT a subgroup of patients suffers from neuropathic symptoms leading to impaired QoL. Additionally, mild hyperalgesia as a possible sensitisation phenomenon should be considered a target for symptomatic treatment.

In the 1990s, selenium was identified as a component of an enzyme that activates thyroid hormone; since this discovery, the relevance of selenium to thyroid health has been widely studied. Selenium, known primarily for the antioxidant properties of selenoenzymes, is obtained mainly from meat, seafood and grains. Intake levels vary across the world owing largely to differences in soil content and factors affecting its bioavailability to plants. Adverse health effects have been observed at both extremes of intake, with a narrow optimum range. Epidemiological studies have linked an increased risk of autoimmune thyroiditis, Graves disease and goitre to low selenium status. Trials of selenium supplementation in patients with chronic autoimmune thyroiditis have generally resulted in reduced thyroid autoantibody titre without apparent improvements in the clinical course of the disease. In Graves disease, selenium supplementation might lead to faster remission of hyperthyroidism and improved quality of life and eye involvement in patients with mild thyroid eye disease. Despite recommendations only extending to patients with Graves ophthalmopathy, selenium supplementation is widely used by clinicians for other thyroid phenotypes. Ongoing and future trials might help identify individuals who can benefit from selenium supplementation, based, for instance, on individual selenium status or genetic profile.Selenium status varies across the world and adverse health effects have been observed at both extremes of intake. This Review discusses the physiological functions of selenium and highlights evidence that selenium status is important in thyroid function. The evidence for selenium supplementation from randomized clinical trials in benign thyroid diseases is also considered.

Chronic lymphocytic thyroiditis (CLT), also known as Hashimoto's thyroiditis, is an autoimmune disease in which the thyroid gland is gradually destroyed. To date, only a limited number of agents can effectively suppress thyroiditis development in CLT patients. The aim of the current study was to investigate the protective effect of emodin on experimental autoimmune thyroiditis (EAT) in mice, which is considered an excellent model for CLT. NaI was used to induce the EAT model in non-obese diabetic (NOD) mice. An ELISA method was employed to detect the TgAb level (thyroid inflammation) in the serum of the EAT mice. The T cell subsets in peripheral blood and spleen were detected by flow cytometry. The histopathological study revealed that the thyroid inflammatory cell infiltration was significantly reduced by emodin compared with the model group. In addition, ELISA assays indicated that the NaI-induced serum TgAb upregulation was dramatically revered by emodin. Moreover, the level of serum IFN-γ and the cell populations of CD3+CD4+IL-4+, CD3+CD4+ IFN-γ+, CD3+CD8+IL-4+, CD3+CD8+ IFN-γ+ T cells in peripheral blood monocytes and splenic lymphocytes were significantly increased by NaI in the model group compared with in the normal group. Nevertheless, this type of increase was markedly attenuated by emodin. To conclude, the EAT model was successfully established by treating NOD mice with NaI. Emodin indicated an inhibitory effect on the autoimmune response that was significantly different in EAT compared with control mice. Furthermore, the anti-inflammatory action of emodin on EAT mice may be mediated via the inhibition of the secretion of IFN-γ and the cell numbers of CD3+CD4+IL-4+, CD3+CD4+ IFN-γ+, CD3+CD8+IL-4+ and CD3+CD8+ IFN-γ+ T cells in the peripheral blood monocytes and splenic lymphocytes. Therefore, the data may offer valuable insight on the efficacy of treatment of CLT with emodin.

BackgroundPrimary Sjogren’s syndrome (pSS) and autoimmune thyroiditis (AIT) share overlapping genetic and immunological profiles. This retrospective study evaluates the efficacy of machine learning algorithms, with a focus on the Random Forest Classifier, to predict the presence of thyroid-specific autoantibodies (TPOAb and TgAb) in pSS patients.MethodsA total of 96 patients with pSS were included in the retrospective study. All participants underwent a complete clinical and laboratory evaluation. All participants underwent thyroid function tests, including TPOAb and TgAb, and were accordingly divided into positive and negative thyroid autoantibody groups. Four machine learning algorithms were then used to analyze the risk factors affecting patients with pSS with positive and negative for thyroid autoantibodies.ResultsThe results indicated that the Random Forest Classifier algorithm (AUC = 0.755) outperformed the other three machine learning algorithms. The random forest classifier indicated Age, IgG, C4 and dry mouth were the main factors influencing the prediction of positive thyroid autoantibodies in pSS patients. It is feasible to predict AIT in pSS using machine learning algorithms.ConclusionsAnalyzing clinical and laboratory data from 96 pSS patients, the Random Forest model demonstrated superior performance (AUC = 0.755), identifying age, IgG levels, complement component 4 (C4), and absence of dry mouth as primary predictors. This approach offers a promising tool for early identification and management of AIT in pSS patients.Trial registrationThis retrospective study was approved and monitored by the Ethics Committee of The Third Affiliated Hospital of Sun Yat-sen University (No.II2023-254-02).

Settings and Design: The aim was to study the changes in thyroid antibody and T lymphocyte subsets after radiofrequency ablation (RFA) of thyroid nodules in patients with autoimmune thyroiditis. Subjects and Methods: Patients (n = 135) with autoimmune thyroiditis and thyroid nodules were treated by RFA. The indices of thyroid function and thyroid antibody and T lymphocyte subsets were examined preoperation and on the 1st day and the 1st month after ablation. Any complications were recorded. Statistical Analysis: The software SPSS 17.0.0 (version: 2008-8-23) running under Windows 8 was used for statistical analysis. The measurement data were expressed as x ± s, with P < 0.01 indicating a significant difference in the statistical data. Results: Levels of free triiodothyronine, free thyroxine, and thyroid-stimulating hormone were in the normal range before ablation, and no significant changes occurred on the 1st day or in the 1st month after ablation. The change in the percentage of CD8+T cells and the absolute value of B cells were not statistically significant (P > 0.01), and the values were in the normal range. Compared with values recorded preoperation, the value of TG-Ab, TPO-Ab, CD4+/CD8+, the percentage of CD4+T cells, the absolute values of lymphocytes, T cells, CD4+T cells, and CD8+T cells decreased significantly at the 1st day after ablation (P < 0.01) and then recovered to preoperative levels during the first 30 days after ablation (P > 0.01). Within 1 month after ablation, none of the patients had complications such as active bleeding, infection, recurrent laryngeal nerve injury, parathyroid gland injury, skin scald, and so on. Conclusions: After RFA of thyroid nodules in patients with autoimmune thyroiditis, thyroid function is not affected and no serious complications occurred. TG-Ab and TPO-Ab levels can be significantly decreased, and the distribution of T lymphocyte subsets can be changed in the short term after ablation.

Background Hashimoto’s thyroiditis (HT) is an organ-specific autoimmune disease characterized by lymphocyte infiltration that destroys thyrocyte cells. The aim of the present study was to elucidate the role and mechanisms of tissue small extracellular vesicle (sEV) microRNAs (miRNAs) in the pathogenesis of HT. Methods Differentially expressed tissue sEV miRNAs were identified between HT tissue and normal tissue by RNA sequencing in the testing set ( n  = 20). Subsequently, using quantitative real-time polymerase chain reaction (qRT‒PCR) assays and logistic regression analysis in the validation set ( n  = 60), the most relevant tissue sEV miRNAs to HT were verified. The parental and recipient cells of that tissue sEV miRNA were then explored. In vitro and in vivo experiments were further performed to elucidate the function and potential mechanisms of sEV miRNAs that contribute to the development of HT. Results We identified that miR-142-3p encapsulated in T lymphocyte-derived tissue sEVs can induce Treg function defect and thyrocyte destruction through an intact response loop. Inactivation of miR-142-3p can effectively protect non-obese diabetic (NOD).H-2 h4  mice from HT development display reduced lymphocyte infiltration, lower antibody titers, and higher Treg cells. Looking at the mechanisms underlying sEV action on thyrocyte destruction, we found that the strong deleterious effect mediated by tissue sEV miR-142-3p is due to its ability to block the activation of the ERK1/2 signaling pathway by downregulating RAC1 . Conclusions Our findings highlight the fact that tissue sEV-mediated miR-142-3p transfer can serve as a communication mode between T lymphocytes and thyrocyte cells in HT, favoring the progression of HT.
