MYTP01 for Immune-Mediated Diseases

The goal of this study is to evaluate whether MYTP01, a traditional Chinese herbal formula developed by clinical experts with the assistance of artificial intelligence (AI), is effective and safe as an additional treatment for immune-mediated diseases (post-kidney transplantation, IgA nephropathy, etc.). The study also aims to explore whether MYTP01 may provide therapeutic benefits across these conditions by regulating shared immune and inflammatory processes. The main questions this study aims to answer are: * Does MYTP01 provide clinical benefits and remain safe when used as an additional treatment for immune-mediated conditions? * Does MYTP01 help regulate immune balance and inflammatory responses across immune-mediated disease populations? Researchers will compare MYTP01 with a matching placebo, with both treatments given in addition to standard medical care, to evaluate clinical efficacy, safety, and potential immunomodulatory effects across immune-mediated conditions. Participants will: * Be enrolled in a disease-specific cohort based on their clinical condition. * Be randomly assigned to receive either MYTP01 or placebo in addition to their usual medical treatment. * Take the assigned study treatment twice daily for 8 weeks. * Attend follow-up visits approximately once a month during a 12-week study period. * Undergo clinical assessments, blood and urine tests, and evaluations of immune function and possible side effects.

The Impact of Change of Thyroid Antibodies on Hormone Level and Disease Burden in Patients With Hashimoto's Thyroiditis

Hashimoto's thyroiditis (HT) is an autoimmune disease affecting the thyroid gland and is one of the most common causes of hypothyroidism. Eating habits may affect the risk of several inflammatory and immune diseases, such as HT. The current knowledge of the diet in HT is insufficient. The Mediterranean diet (MD) is an anti-inflammatory diet characterized by frequent consumption of olive oil, unrefined cereals, fresh or dried fruit and vegetables, moderate amounts of fish, dairy, and meat, and many condiments and spices. It is rich in nutrients and bioactives, which have the potential to offer anti-inflammatory aspects.

Role of Total Thyroidectomy in Relieving Local Symptoms in Hashimoto's Thyroiditis

This study aims to evaluate the role and effectiveness of total thyroidectomy in relieving compressive and local symptoms (such as dysphagia, dyspnea, and anterior neck pain/discomfort) in patients with Hashimoto's thyroiditis who fail to improve with conservative medical management.

Thyroid Disorders in Pediatric Autoimmune Hepatitis

This cross-sectional study aims to determine the frequency and spectrum of thyroid disorders among children with autoimmune hepatitis attending Assiut University Children's Hospital.

Colchicine for Autoimmune and Subacute Thyroiditis

Thyroiditis includes inflammatory thyroid disorders such as Hashimoto's thyroiditis and subacute thyroiditis. These conditions may cause thyroid pain, neck tenderness, elevated inflammatory markers, thyroid dysfunction, fatigue, and recurrence. Current management includes observation, symptomatic treatment, nonsteroidal anti-inflammatory drugs, and corticosteroids. Although corticosteroids may be effective, relapse after tapering and treatment-related adverse effects remain limitations. Colchicine is hypothesized to reduce inflammatory activity and may improve biochemical and clinical recovery. This study will evaluate the efficacy and safety of low-dose colchicine compared with corticosteroid therapy and supportive care in adults with autoimmune or subacute thyroiditis.

rT3 and Inflammation in Hashimoto's Thyroiditis

Hashimoto's thyroiditis (HT) is characterized by an enlarged thyroid gland infiltrated with lymphocytes. The incidence of HT is estimated to be 0.3-1.5 cases per 1000 people, with a female/male predominance of 7-10:1. It has a strong association with other autoimmune diseases. The autoimmune presentation of HT relies on the interaction between environmental factors and genetic background such as human leukocyte antigen (HLA), T lymphocyte-associated 4 (CTLA-4), protein tyrosine phosphatase, non-receptor type 22 (PTPN22) genes, and X chromosome inactivation patterns, leading to an imbalance between self-tolerance mechanisms maintained by regulatory T and B lymphocytes. Furthermore, genetic polymorphisms in self antigens, cytokines and their receptors (e.g., interleukin 2 receptor IL2R), estrogen receptors, adhesion molecules (CD14, CD40), the promoter region of selenoprotein S, and apoptosis-related gene products have been associated with thyroid autoimmunity. Genetic factors account for 70-80% of the risk in the development of Hashimoto's disease, while environmental factors account for 20-30%. HT is diagnosed based on clinical symptoms, antithyroid antibodies, and histological features. Ultrasound imaging of the thyroid gland can aid in differential diagnosis, especially in patients with thyroid peroxidase antibody (TPOAb) negative HT. Ultrasound features of HT include decreased echogenicity, heterogeneity, hypervascularity, and the presence of small cysts. Hashimoto's disease can have stages presenting with hyperthyroidism, euthyroidism, and hypothyroidism. In diagnosis, hyperthyroidism, euthyroidism, and hypothyroidism are determined based on measurements of thyroid-stimulating hormone (TSH), free T4 (sT4), and free T3 (sT3), which are biochemical parameters used. Hashimoto's thyroiditis is an inflammatory condition affecting the thyroid gland, and patients develop clinical thyroid dysfunction depending on the duration of the disease. HT causes atrophy of the thyroid parenchyma through autoimmune processes and chronic inflammation. This leads to an increase in inflammatory load in patients with Hashimoto's. Studies have shown that inflammation associated with HT may not be limited to the thyroid gland and can trigger a systemic inflammatory process even in patients with normal thyroid function. Reverse T3 (3,3',5'-triiodothyronine or rT3) is the third most abundant iodothyronine circulating in human blood and is produced by deiodination of the inner ring of the prohormone thyroxine (T4). Unlike the more abundant and active metabolite T3, serum rT3 measurement has not yet found routine clinical application. While rT3 has little effect on nuclear thyroid hormone receptors (THR), it has been shown to interact with more recently identified non-nuclear thyroid hormone receptors. rT3 analysis is useful in confirming the diagnosis of non-thyroid disease syndrome, in measuring the T3/rT3 ratio in insulin-resistant patients, and in hemangiomas where iodothyronine deiodinase type 3 (DIO3) overexpression causes an increase in rT3. rT3 analysis also has the potential to identify situations where the diagnosis of hypothyroidism may be masked by concomitant drug treatment or potentially function as a marker of drug effect. The aim of this study is to compare rT3 levels in anti-TPO-positive euthyroid Hashimoto's patients with or without thyroid hormone replacement therapy. The impact of drug use on hormone levels in these patient groups will be investigated. Additionally, systemic inflammatory markers derived from the complete blood count will be examined to determine the systemic inflammatory load in these patients.

Comparison of the Effect of Gluten-Free-Lactose-Free / Aronia Melanocarpa Supplemented Diet in Patients With Hashimoto's Thyroiditis

Hashimoto's thyroiditis (HT) is the most common cause of chronic hypothyroidism in areas with sufficient iodine, stemming from an autoimmune response against thyroid peroxidase and/or thyroglobulin. It is the most prevalent autoimmune thyroid disease and a leading cause of overall hypothyroidism. Even when they reach euthyroidism, 82% of treated women with HT still have excess body weight, and 35% of them are obese. Thyroid dysfunction can affect the function of adipose tissue and lead to metabolic disturbances. Leptin can stimulate thyroid-stimulating hormone secretion, while thyroid-stimulating hormone can influence leptin release from adipose tissue. Additionally, HT patients often exhibit high levels of C-reactive protein and interleukin-6, suggesting an association between increased thyroid-stimulating hormone levels and the inflammatory process, which may contribute to comorbid disease risk in individuals with HT. Nutrition can serve as a complementary treatment for HT by affecting thyroid functions and having anti-inflammatory properties. Dietary interventions may involve eliminating gluten, lactose, or certain food components, or focusing on an anti-inflammatory dietary pattern while preventing nutritional deficiencies. Therefore, this study is a randomized controlled, single-blind trial designed to evaluate the effects of a gluten-free, lactose-free diet and a diet enriched with Aronia Melanocarpa, both individually and in combination, as well as healthy dietary protocols, on autoantibody levels, leptin, ghrelin, oxidative response, and weight loss in patients with Hashimoto's thyroiditis. The study aims to recruit a minimum of 80 participants aged 18-65 years, diagnosed with Hashimoto's thyroiditis at Istanbul Medical Faculty Hospital. In the initial face-to-face interview, participants will provide sociodemographic information, dietary habits, anthropometric measurements, and dietary intake records through a questionnaire. The study involves the inclusion of Aronia Melanocarpa in the diet (high anthocyanin content, 69.24 mg/100 ml), a gluten-free and lactose-free diet, both interventions being applied together, and the application of only healthy nutrition protocols to patients over an 8-week period, with serum assessments of thyroid-stimulating hormon, free T4, free T3, anti-thyroid peroxidase, anti-Tg, interleukin-6,anti tumor necrosis factor alpha, C-reactive protein and leptin-ghrelin levels at the beginning and end of the study. The goal is to create recommendations for patients, improve their quality of life, and establish sustainable nutritional interventions.
