Introduction: Graves\' disease (GD) is the most common cause of hyperthyroidism and can affect multiple systems of the body. Currently, commonly-used treatment methods for GD have a series of shortcomings. In contrast, traditional Chinese medicine has been proven to be effective in inhibiting the progression of GD and is expected to become a key direction for the development of new drugs in the future. Therefore, a network meta-analysis was performed to compare the impacts of different traditional Chinese medicines on the curative effect, thyroid-stimulating hormone (TSH), free triiodothyronine (FT3), free thyroxine (FT4), thyroglobulin antibody (TGAb), thyroid peroxidase antibody (TPOAb) and thyrotropin receptor antibody (TRAb) in patients with GD. Methods: PubMed, Embase, Cochrane Library, Web of Science, WanFang, Weipu, and CNKI were searched for the randomized controlled trials of traditional Chinese medicine on GD patients up to 19 December 2023. The quality of the included studies was evaluated regarding the risk of bias, and the data were analyzed by R software. Results: Thirty-five articles were included in the analysis, involving 2828 GD patients and traditional Chinese medicines including Bailing Capsule, Jinshuibao Capsule, Astragalus injection, Jiakangling Tablet, Jiakangling Capsule, Tripterygium Wilfordii, Sanjie Xiaoying Decoction, Prunella vulgaris (L.) Oral Liquid, P. vulgaris (L.) Granules, Xiehuo Xiaoying Recipe, Xiehuo Yangyin Powder, Yikang Pill and Yinjia Pellet. The results of network meta-analysis suggested that for GD patients, Bailing Capsule, Jiakangling Capsule, Tripterygium wilfordii, P. vulgaris (L.) Oral Liquid and Yinjia Pellet had better curative effect compared with Western medicine. Prunella vulgaris (L.) Granules and Yikang Pill could improve the TSH level. Prunella vulgaris (L.) Granules, P. vulgaris (L.) Oral Liquid and Yikang Pill could reduce FT3 level. Jiakangling Capsule, P. vulgaris (L.) Granules, P. vulgaris (L.) Oral Liquid and Yikang Pill could reduce the FT4 level. Prunella vulgaris (L.) Oral Liquid can reduce the level of TPOAb and TRAb. Besides, Yinjia Pellet was the most helpful in improving the curative effect. Yikang Pill could best improve TSH. Prunella vulgaris (L.) Granules had the best effect on reducing FT3. Prunella vulgaris (L.) Granules performed best in reducing FT4. Prunella vulgaris (L.) Oral Liquid had the most favorable effect on reducing TPOAb and TRAb. Conclusion: Based on the current research, it is safe to conclude that Chinese medicine can improve the curative effect and TSH level of patients with GD, and reduce the levels of FT3, FT4, TPOAb and TRAb. Besides, Yinjia Pellet is the most helpful in improving the curative effect. Yikang Pill can best improve TSH. Prunella vulgaris (L.) Granules have the best effect on reducing FT3. Prunella vulgaris (L.) Granules perform best in reducing FT4. Prunella vulgaris (L.) Oral Liquid has the most favorable effect on reducing TPOAb and TRAb.

UNASSIGNED: T-cell exhaustion (Tex) can be beneficial in autoimmune diseases, but its role in Graves\' disease (GD), an autoimmune disorder of the thyroid, remains unknown. This study investigated Tex-related gene expression in GD patients to discern the potential contributions of these genes to GD pathogenesis and immune regulation.
UNASSIGNED: Through gene landscape analysis, a protein-protein interaction network of 40 Tex-related genes was constructed. mRNA expression levels were compared between GD patients and healthy control (HCs). Unsupervised clustering categorized GD cases into subtypes, revealing distinctions in gene expression, immune cell infiltration, and immune responses. Weighted gene co-expression network analysis and differential gene expression profiling identified potential therapeutic targets. RT-qPCR validation of candidate gene expression was performed using blood samples from 112 GD patients. Correlations between Tex-related gene expression and clinical indicators were analyzed.
UNASSIGNED: Extensive Tex-related gene interactions were observed, with six genes displaying aberrant expression in GD patients. This was associated with atypical immune cell infiltration and regulation. Cluster analysis delineated two GD subtypes, revealing notable variations in gene expression and immune responses. Screening efforts identified diverse drug candidates for GD treatment. The Tex-related gene CBL was identified for further validation and showed reduced mRNA expression in GD patients, especially in cases of relapse. CBL mRNA expression was significantly lower in patients with moderate-to-severe thyroid enlargement than in those without such enlargement. Additionally, CBL mRNA expression was negatively correlated with the disease-specific indicator thyrotropin receptor antibodies.
UNASSIGNED: Tex-related genes modulate GD pathogenesis, and their grouping aids subtype differentiation and exploration of therapeutic targets. CBL represents a potential marker for GD recurrence.

BACKGROUND: Graves\' disease (GD) is an autoimmune disorder characterized by hyperthyroidism due to increased thyroid-stimulating hormone receptor antibodies (TRAb).The treatment of GD often consists of radioactive iodine therapy, anti-thyroid drugs (ATD), or thyroidectomy. Since few studies have collected data on remission rates after treatment with ATD in Saudi Arabia, our study aimed to assess the efficacy and the clinical predictors of GD long-term remission with ATD use.
METHODS: We conducted a retrospective chart review study of 189 patients with GD treated with ATD between July 2015 and December 2022 at the endocrine clinics in King Abdulaziz Medical City in Riyadh. All GD patients, adults, and adolescents aged 14 years and older who were treated with ATD during the study period and had at least 18 months of follow-up were included in the study. Patients with insufficient follow-up and those who underwent radioactive iodine (RAI) therapy or thyroidectomy as first-line therapy for GD were excluded from the study.
RESULTS: The study sample consisted of 189 patients, 72% of whom were female. The patients\' median age was 38years (33, 49). A total of 103 patients (54.5%) achieved remission. The median follow-up period for the patients was 22.0 months (9, 36). Patients who achieved remission had lower mean free T4 levels (25.8pmol/l ± 8.93 versus 28.8pmol/l ± 10.82) (P value = 0.038) and lower median TRAb titer (5.1IU/l (2.9, 10.7)) versus (10.5IU/l (4.2, 22.5)) (P value = 0.001) than patients who did not achieve remission. Thirty-five out of 103 patients who achieved remission (34%) relapsed after ATD discontinuation. The patients who relapsed showed higher median thyroid uptake on 99mTc-pertechnetate scan than patients who did not relapse: 10.3% (5.19, 16.81) versus 6.0% (3.09, 12.38), with a P value of 0.03. They also received ATD for a longer period, 40.0 months (29.00, 58.00) versus 25.0 months (19.00, 32.50), with a P value of < 0.0001.
CONCLUSIONS: The remission of GD was achieved in approximately half of the patients treated with ATD; however, approximately one-third of them relapsed. Lower Free T4 and TRAb levels at diagnosis were associated with remission. Longer ATD use and higher thyroid uptake upon diagnosis were associated with relapse after ATD discontinuation. Future studies are necessary to ascertain the predictors of ATD success in patients with GD.

Almost a century has passed since Plummer reported the efficacy of short-term preoperative inorganic iodine therapy for Graves\' disease in the 1920s. Since there were concerns about the escape phenomenon and exacerbation with inorganic iodine, antithyroid drugs became the mainstay of pharmacotherapy for Graves\' disease following their development in the 1940s. With regard to long-term inorganic iodine monotherapy, Trousseau reported a case in the 1860s, and several subsequent reports suggested its efficacy. Around 1930, Thompson et al. published a number of papers and concluded that long-term inorganic iodine monotherapy was useful if limited to mild cases under careful follow-up. From Japan, in 1970, Nagataki et al. reported that, of 12 patients treated with inorganic iodine, three remained eumetabolic for more than two years. Since 2014, some reports have also been published from Japan. A summary of these recent reports is given below. The starting dose of potassium iodide is around 50 mg/day, and candidate responders have mild disease, with FT4 <2.76 ng/dL (35.5 pmol/L), a small goiter, and are female and elderly. Response rates are relatively high, at 60-80%, and the remission rate is about 40%. In cases of insufficient response, changing therapy should be considered. Inorganic iodine can be used as a possible alternative if the patient experiences adverse events with antithyroid drugs and/or prefers conservative treatments, with an understanding of their efficacy and limitations. These recent reports have been published from Japan, where iodine is sufficient, and the dose of inorganic iodine is empirical and requires further study.

Composed of over 1200 species of anaerobes and aerobes bacteria along with bacteriophages, viruses, and fungal species, the human gut microbiota (GM) is vital to health, including digestive equilibrium, immunologic, hormonal, and metabolic homeostasis. Micronutrients, usually refer to trace elements (copper, iodine, iron, selenium, zinc) and vitamins (A, C, D, E), interact with the GM to influence host immune metabolism. So far, microbiome studies have revealed an association between disturbances in the microbiota and various pathological disorders, such as anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis, anxiety, depression, early-onset cancers, type 1 diabetes (T1D) and type 2 diabetes (T2D). As common conditions, thyroid diseases, encompassing Graves\' disease (GD), Graves\' orbitopathy (GO), Hashimoto\'s thyroiditis (HT), benign nodules, and papillary thyroid cancer (TC), have negative impacts on the health of all populations. Following recent studies, GM might play an integral role in triggering diseases of the thyroid gland. Not only do environmental triggers and genetic predisposing background lead to auto-aggressive damage, involving cellular and humoral networks of the immune system, but the intestinal microbiota interacts with distant organs by signals that may be part of the bacteria themselves or their metabolites. The review aims to describe the current knowledge about the GM in the metabolism of thyroid hormones and the pathogenesis of thyroid diseases and its involvement in the appearance of benign nodules and papillary TC. We further focused on the reciprocal interaction between GM composition and the most used treatment drugs for thyroid disorders. However, the exact etiology has not yet been known. To elucidate more precisely the mechanism for GM involvement in the development of thyroid diseases, future work is needed.

Fetal and neonatal thyrotoxicosis occurs in up to 5% of pregnancies in mothers with Graves\' disease (GD). This condition is caused by stimulating antibodies against the thyrotropin receptor (TRAbs) that cross the placenta and may stimulate the fetal thyroid, typically in the second half of pregnancy. GD is often treated with radioiodine, resulting in hypothyroidism in most patients, but TRAbs can persist for several years. Even if a pregnant mother is hypothyroid after radioiodine therapy or surgery, her TRAbs can still, although rarely, induce fetal hyperthyroidism. In this review, we first present two cases of neonatal hyperthyroidism in mothers with GD who became hypothyroid after prior radioiodine therapy, identified through a 10-year analysis of the National Perinatal System in Slovenia. Based on these cases, we provide an overview of existing data on this rare clinical condition in neonates. We also discuss the underlying mechanisms and clinical outcomes based on currently available data. In conclusion, our review highlights the importance of careful monitoring during pregnancy in all women with GD, even in those well managed after radioiodine therapy or surgery.

Graves\' disease (GD) is the leading cause of hyperthyroidism in children. However, compared to adults GD in children is a rare condition. In a recent guideline issued by the European Thyroid Association the diagnostic evaluation and treatment of pediatric GD is described extensively. In this article we go beyond the guideline and describe the potential challenges of establishing the right etiology of thyrotoxicosis in children, illustrated by cases of thyroid hormone resistance, autonomous functioning thyroid nodules and subacute thyroiditis with a thyrotoxic phase. In addition, we report therapeutic challenges in pediatric GD such as recurrent immunological flare-ups under anti-thyroid drug (ATD) treatment, innovative ways to improve ATD compliance and the role of definitive treatment in persistent complaints of malaise under ATD treatment.

Ectopic thyroid tissue is rare in the general population and more prevalent in people who have existing thyroid disease. Common anatomical sites of ectopic thyroid tissue include the lateral cervical region, thyroglossal duct, mediastinum, lingual, sublingual, and submandibular region. Intrathymic ectopic thyroid tissue is exceedingly rare. The purpose of this report is to describe one such case in a 52-year-old African-American female with Graves\' disease. The patient presented for a physical exam and follow-up. During the exam, an incidental mediastinal mass was discovered, which was evaluated by imaging studies and subsequently was resected. Histologically, the mass was composed of variable-sized thyroid follicles lined by a monolayer of cuboidal to columnar follicular epithelial cells and filled with eosinophilic colloid, surrounded by a rim of unremarkable compressed thymic tissue.

UNASSIGNED: The purpose of this study is to evaluate the usage of oxymetazoline hydrochloride ophthalmic solution, 0.1% in the treatment of Graves\' disease to improve lid symmetry.
UNASSIGNED: Fourteen patients were identified with unilateral upper eyelid retraction, secondary to Graves\' disease. A phenylephrine test was performed to evaluate whether treating the unaffected (non-retracted) side would result in improved symmetry using Hering\'s law. Patients were prescribed oxymetazoline hydrochloride ophthalmic solution, 0.1% to instill into the unaffected eye. Marginal reflex distance 1 (MRD1) measurements were taken pre- and post-treatment and patient satisfaction surveys were completed.
UNASSIGNED: The average pre-treatment MRD1 difference between the right eye (OD) and the left eye (OS) was 2.46 [range 1.50-4.00]. The average post-treatment MRD1 difference between OD and OS was 0.39 [range 0.00-1.00]. One hundred percent of patients were satisfied or very satisfied with the improvement in symmetry.
UNASSIGNED: Oxymetazoline hydrochloride ophthalmic solution, 0.1% is a potential method to improve symmetry in patients with Graves\' disease and unilateral upper eyelid retraction via Hering\'s law, especially for non-surgical candidates or those who prefer non-surgical treatment. Our results indicate improved MRD1 differences between fellow eyes and patient satisfaction regarding the symmetry of the upper eyelids.

We present two cases of epilepsy associated with Graves\' disease. Case 1 is a 22-year-old woman. She had three epileptic seizures and was diagnosed with idiopathic generalized epilepsy. She was treated with valproic acid (VPA). She was later diagnosed with Graves\' disease, and treated with antithyroid medication (thiamazole). We added a thyroid medication (levothyroxine) because of a decrease in free thyroxine observed with antithyroid medication. Case 2 is an 18-year-old woman. She had three epileptic seizures and was diagnosed with juvenile myoclonic epilepsy and treated with VPA. Then, she was diagnosed with Graves\' disease and was treated with thiamazole. Levothyroxine was added due to low fT4 induced by thiamazole. Due to poor compliance with antithyroid medication, the thyroid functional status was not stable. Both patients became seizure-free and euthyroid after VPA and thiamazole treatments.
