Background: Hashimoto's thyroiditis (HT) is an inflammatory disease characterized by increased reactive oxygen species. Diets rich in anti-inflammatory and antioxidant properties may be linked to a reduced risk of developing HT. The aim of this study was to investigate the association between the dietary inflammatory index (DII) and dietary total antioxidant capacity (DTAC) with HT in Iranian adults. Methods: The study was a hospital-based case-control study conducted on 230 participants (115 cases and 115 controls). Dietary intake was assessed using a food frequency questionnaire (FFQ). The FFQ data were used to calculate DII and DTAC scores. Anthropometric measurements, thyroid function, and antibody tests were evaluated using standard methods. Multivariable logistic regression analysis was performed in both raw and adjusted models to determine the association between DII and DTAC scores with HT. Results: The average age of the participants was 39.76 ± 9.52 years. The mean body mass index in the case and control groups was 28.03 ± 6.32 and 26.43 ± 5.13 (kg/m2), respectively (P = 0.036). In the HT group, the DII level was higher (P < 0.001) and the DTAC level was lower than those in the healthy group (P = 0.047). In the multivariable logistic regression model, after adjusting for confounding factors, subjects in the last tertile of DII had a nonsignificantly higher HT risk than those in the first tertile (OR = 1.75; 95% CI = 0.83–3.65; P = 0.130). Regarding DTAC, the subjects in the last tertile of DTAC had a significantly decreased risk of HT (OR = 0.47; 95% CI = 0.23–0.98; P = 0.043) compared to those in the first tertile. The DII had a positive correlation with anti-thyroid peroxidase antibody (anti-TPO), thyroglobulin antibodies (TG-Ab) and thyroid-stimulating hormone, while DTAC had a negative correlation with anti-TPO and TG-Ab (P < 0.050). Conclusion: The increase in DII is not associated with an increase in the risk of HT, while DTAC can significantly reduce its risk. Having an anti-inflammatory and antioxidative diet can be effective in improving thyroid function. These conclusions should be confirmed in additional prospective studies. [ABSTRACT FROM AUTHOR]

Background: Micronutrients play pivotal roles in modulating various aspects of the immune response. However, the existing literature on the association between micronutrients and autoimmune thyroiditis (AIT) remains limited and contentious. To address this gap, we conducted Mendelian randomization (MR) to investigate potential links between genetically predicted concentrations of six micronutrients (Copper (Cu), Iron (Ir), Calcium (Ca), Vitamin D (VD), Vitamin C (VC), Zinc (Zn)) and the risk of AIT. Method: Utilizing summary statistics from genome-wide association studies (GWAS) in individuals of European descent, we employed MR methodologies to elucidate the interplay between micronutrients and AIT. Three distinct MR techniques were employed: Inverse Variance Weighted (IVW), MR-Egger regression, and Weighted Median Estimator (WME). Additionally, we evaluated outcome heterogeneity using Cochran’s Q statistic and assessed pleiotropy using the MR-Egger intercept. Result: IVW analysis revealed no substantial evidence supporting a significant impact of genetically predicted micronutrient concentrations on AIT risk (Cu: OR = 0.918, P = 0.875; Ir: OR = 0.653, P = 0.264; Ca: OR = 0.964, P = 0.906; VD: OR = 0.717, P = 0.378; VC: OR = 0.986, P = 0.875; Zn: OR = 0.789, P = 0.539). Cochran’s Q test for IVW indicated no notable heterogeneity. Moreover, the MREgger intercept method suggested the presence of horizontal pleiotropy between serum VC levels and AIT (MR-Egger intercept = −0.037, p = 0.026), while no such pleiotropy was observed for other micronutrients. Conclusion: Our MR analysis does not support a causal relationship between genetically predicted concentrations of six micronutrients (Cu, Ir, Ca, VD, VC, and Zn) and the risk of AIT.

This article discusses a retrospective cohort study that aimed to predict relapse in patients with chronic spontaneous urticaria (CSU) who were treated with omalizumab. CSU is a condition that affects a small percentage of the population and significantly impacts patients' quality of life. Omalizumab is the only registered therapy for CSU, but its discontinuation remains uncertain. The study found that approximately 30% of patients achieved long-term remission after 24 weeks of therapy, and most relapse episodes occurred within the first 6 weeks after treatment discontinuation. Factors such as higher Urticaria Activity Score (UAS7) after 24 weeks, longer time to treatment, and prior relapses increased the risk of relapse, while Hashimoto's disease favored remission. The findings can help determine appropriate treatment duration and withdrawal regimens. Further research is needed to optimize omalizumab withdrawal and identify additional predictive factors for long-term remissions and relapse rates in CSU patients. [Extracted from the article]

Objectives: To study the relationship between the ablation range and applied energy of laser ablation (LA) and microwave ablation (MWA) in papillary thyroid microcarcinoma (PTMC). Methods: A total of 201 PTMC patients were treated with LA (n = 102) or MWA (n = 99) with single-applicator fixed ablation. The ablation range was determined by contrast-enhanced ultrasound. The ratios of ablation volume, longitudinal diameter, and orthogonal diameter to ablation energy (RAV/E, RAL/E, RAO/E) were analyzed and compared between MWA and LA. The effects of PTMC characteristics and Hashimoto's thyroiditis (HT) on ablation efficiency were evaluated by linear regression. Results: The RAV/E was 0.72 (0.65–0.84) mm3/J for MWA and 0.48 (0.39–0.54) mm3/J for LA. HT was significantly correlated with RAV/E of LA (coefficient = − 0.367, p < 0.0001). RAL/E did not differ significantly between MWA and LA (MWA 0.026 mm/J, LA 0.025 mm/J; p = 0.957). However, MWA had a greater RAO/E than LA (MWA 0.014 mm/J, LA 0.012 mm/J; p < 0.0001). The plateau values of MWA and LA on the ablation orthogonal diameter were 10.7 mm and 8.69 mm, respectively. Conclusions: MWA showed a higher RAV/E than LA. More intuitively, MWA had a better ablation performance than LA on the orthogonal axis rather than the longitudinal axis. Theoretically, MWA and LA could achieve complete ablation of ≤ 6.70 mm and ≤ 4.69 mm PTMC separately by single-applicator fixed ablation considering a unilateral 2-mm safe margin. HT had a negative effect on LA but not on MWA. Clinical relevance statement: This study establishes strong connections between ablation energy and ablation range in papillary thyroid microcarcinoma (PTMC) in vivo, possibly contributing to the supplementation of the PTMC Ablation Consensus or Guidelines and providing a scientific basis for choosing clinical ablation parameters in PTMC. Key Points: • Both microwave ablation (MWA) and laser ablation (LA) have excellent performance on the ablation longitudinal axis (easily exceeding 10 mm) for papillary thyroid microcarcinoma (PTMC). • MWA performed much better than LA on the ablation orthogonal axis. • MWA and LA are expected to achieve complete ablation of ≤ 6.70 mm and ≤ 4.69 mm PTMC separately by single-applicator fixed ablation considering a unilateral 2-mm safe margin.

Purpose: Although the potential association between autoimmune thyroiditis and papillary thyroid cancer (PTC) has been acknowledged, whether the clinicopathological features of PTC will be affected by thyroid autoantibodies remains unknown. Patients and methods: We conducted a case-control study to investigate the association of thyroid autoantibodies with clinicopathological characteristics of PTC in 15,305 patients (including 11,465 females and 3,840 males) from 3 medical centers in the central province of China. Logistic regression and restricted cubic spline models were performed to analyze the association of thyroid autoantibodies with clinicopathological features of PTC. Results: In total, out of the 15,305 patients enrolled in this study, 10,087 (65.9%) had negative thyroid autoantibodies, while 5,218(34.1%) tested positive thyroid autoantibodies. Among these individuals, 1,530(10.0%) showed positivity for TPOAb only, 1,247(8.2%) for TGAb only and a further 2,441(15.9%) exhibited dual positivity for both TPOAb and TGAb combined. Thyroid autoantibodies level demonstrated significant correlations with certain aggressive features in PTC. Specifically, TGAb level displayed a direct correlation to an increased likelihood of multifocality, bilateral tumor, extrathyroidal extension, lymph node metastasis, as well as more than five affected lymph nodes. However, TPOAb level exhibited an inverse association with the risk associated with extrathyroidal extension, lymph node metastasis, and more than five affected lymph nodes. Conclusion: Elevated level of TGAb were positively correlated with the risk of aggressive features in PTC, while high level of TPOAb were inversely associated with the risk of extrathyroidal extension and lymph node metastasis.

Background: Although descriptive studies have found an association between thyroid dysfunction (TD) and alopecia areata (AA), however, the causal relationship between TD and AA remains unclear. The purpose of this study is to investigate the causal relationship between the two and the specific directions. Methods: We performed large-scale, two-sample Mendelian randomization (MR) analyses to examine whether there was an association between TD (such as Graves' disease (GD), Hashimoto's thyroiditis (HT), thyroid cancer (TC), thyroid stimulating hormone (TSH), thyrotropin-releasing hormone (TRH), etc.) and AA. Genome-wide association study (GWAS) summary statistics for TD and AA were from the IEU OpenGwas project. The inverse variance-weighted (IVW) method was used as the primary analysis method to evaluate the causality between TD and AA, supplemented by the weighted median, MR-Egger, simple mode and weighted mode. In addition, sensitivity analyses were performed to assess the reliability of the study results. Results: Our study found that single nucleotide polymorphisms (SNPs) in HT (IVW OR = 1.396, 95% CI 1.030-1.892, P=0.031) and hypothyroidism (IVW OR = 1.431, 95% CI 1.138-1.799, P=0.002) significantly increased the risk of AA. Reverse MR analysis indicated that genetic susceptibility to AA (b=-0.029, 95%CI=-0.051 to -0.007, P=0.009) may be a risk for TRH. Positive MR analysis observed no statistically significant causal relationship between other TD and AA (IVW P>0.05). Reverse MR analysis also showed no statistically significant association between AA and other TD (IVW P>0.05) other than TRH. Furthermore, additional sensitivity analyses were performed, including a leave-one-out test, a heterogeneity test, and a pleiotropy test to assess the robustness of the results. Conclusions: This study provides a very comprehensive analysis of the causal relationship between TD and AA, providing convincing genetic evidence to support the causal relationship between TD and alopecia areata. It reveals some causes of AA patients, which is of great significance for the management and treatment of AA patients. [ABSTRACT FROM AUTHOR]

Background: The mechanism and impact of Hashimoto's disease (HT) in patients with papillary thyroid carcinoma (PTC) remains a subject of ongoing debate. The optimal extent of thyroid resection is also controversial in cases of low-risk PTC. Objective: To investigate the clinical outcomes and prognoses associated with different extents of surgical resection in patients diagnosed with PTC coexisting with HT. Methods: We retrospectively analyzed data on the clinical features and treatment outcomes of patients with PTC concomitant with HT who underwent lobectomy with isthmusectomy and those who underwent total thyroidectomy at Peking University International Hospital between December 2014 and August 2023. Results: Twenty-one patients in group A underwent lobectomy with isthmusectomy and prophylactic central neck dissection, whereas twenty patients in group B underwent total thyroidectomy with prophylactic central lymph node (LN) dissection, except one who did not undergo LN dissection. Group A demonstrated shorter surgery time (105.75 min ± 29.35 vs. 158.81 min ± 42.01, p = 0.000), higher parathyroid hormone (PTH) levels on postoperative day 1 [26.96 pg/ml (20.25, 35.45) vs. 9.01 pg/ml (2.48, 10.93), p = 0.000] and a shorter postoperative hospital stay [2.95 d (2.0, 4.0) vs. 4.02 d (3.0, 5.0), p = 0.008] than those of group B, with statistically significant differences. Both groups exhibited similar recovery patterns in terms of PTH [32.10 pg/ml (22.05, 46.50) vs. 20.47 pg/ml (9.43, 34.03), p = 0.192] and serum calcium (2.37 mmol/L ± 0.06 vs. 2.29 mmol/L ± 0.19, p = 0.409) after 1 month following the surgery. According to the Kaplan-Meier curves, no significant difference in the 5-year disease-free survival rates were observed between patients in group A (100%) and group B (97.1%) (Log rank test: p = 0.420, Breslow test: p = 0.420). Conclusion: Lobectomy with isthmusectomy and prophylactic central neck dissection is a safe and feasible treatment option for patients with low-risk PTC coexisting with HT. [ABSTRACT FROM AUTHOR]

Studies have been conducted on the relationship between depression and thyroid diseases and function, its causal relationship remains unclear. Using summary statistics of genome-wide association studies of European and East Asian ancestry, we conducted 2-sample bidirectional Mendelian randomization to estimate the association between MDD and thyroid function (European: normal range TSH, T4, T3, fT4, TPOAb levels and TPOAb-positives; East Asian: T4) and thyroid diseases (hypothyroidism, hyperthyroidism, and Hashimoto's thyroiditis), and used Mediation analysis to evaluate potential mediators (alcohol intake, antidepressant) of the association and calculate the mediated proportions. It was observed a significant causal association between MDD on hypothyroidism (P = 8.94 × 10−5), hyperthyroidism (P = 8.68 × 10−3), and hashimoto's thyroiditis (P = 3.97 × 10−5) among European ancestry, which was mediated by Alcohol intake (alcohol intake versus 10 years previously for hypothyroidism (P = 0.026), hashimoto's thyroiditis (P = 0.042), and alcohol intake frequency for hypothyroidism (P = 0.015)) and antidepressant (for hypothyroidism (P = 0.008), hashimoto's thyroiditis (P = 0.010)), but not among East Asian ancestry (P MDD-hypothyroidism = 0.016, but β direction was different; P MDD-hyperthyroidism = 0.438; P MDD-hashimoto ' s thyroiditis = 0.496). There was no evidence for bidirectional causal association between thyroid function mentioned above and MDD among both ancestry (all P > 0.05). We importantly observed a significant causal association between MDD on risk of hypothyroidism, hyperthyroidism, and hashimoto's thyroiditis among European ancestry, and Alcohol intake and antidepressant as mediators for prevention of hypothyroidism, hashimoto's thyroiditis attributable to MDD. • We conducted 2-sample bidirectional Mendelian randomization to estimate the association between MDD and thyroid diseases among European and East Asian ancestry and Mediation analysis to evaluate potential mediators (alcohol intake and antidepressant). • It was observed a significant causal association between MDD on hypothyroidism, hyperthyroidism, and hashimoto's thyroiditis among European ancestry, in which MDD on hypothyroidism and hashimoto's thyroiditiswas were mediated by Alcohol intake and antidepressant, but not among East Asian ancestry. • These findings may lead to a shift in personalizing treatment in the future.

Background and objective: The prevalence of thyroid cancer (TC) has exhibited an upward trajectory in recent years. An accelerating amount of evidence shows a significant association between Hashimoto's thyroiditis (HT) and TC. The present study encompasses a meticulously designed systematic review and meta-analysis with the aim of scrutinizing the risk of TC and clarifying sex disparities in HT. Methods: A comprehensive search was conducted across reputable online databases, including PubMed, Cochrane Library, EMBASE, and Web of Science. English-language publications on the correlation between HT and TC were examined without temporal restrictions. Two authors independently screened the articles and extracted pertinent data. The collected data underwent statistical analysis using the STATA software, enabling the calculation of the pooled Odds Ratio (OR) and 95% confidence intervals (CI). Additionally, a supplementary analysis was conducted on studies incorporating sex-specific data to determine the OR (female vs. male) and the sex-based prevalence of TC in HT. Results: A total of 2,845 records were obtained, and 26 retrospective studies were included in this meta-analysis. The results indicated a significant role for HT in TC (OR: 2.22, 95% CI: 1.85–2.67). Supplementary analysis indicated that the prevalence of TC in HT patients was lower in women (0.31, 95% CI: 0.17–0.45) than in men (0.37, 95% CI: 0.21–0.53). However, the result was not statistically significant. Conclusion: This systematic review and meta-analysis provide evidence that HT is associated with increasing odds of TC. Regular review of HT patients holds positive clinical significance. [ABSTRACT FROM AUTHOR]

AUTOIMMUNE thyroiditis , *DEUBIQUITINATING enzymes , *PYROPTOSIS , *NLRP3 protein , *CASPASES - Abstract
Background: Inflammatory diseases are often initiated by the activation of inflammasomes triggered by pathogen-associated molecular patterns (PAMPs) and endogenous damage-associated molecular patterns (DAMPs), which mediate pyroptosis. Although pyroptosis resulting from aberrant inflammasome triggering in thyroid follicular cells (TFCs) has been observed in Hashimoto's thyroiditis (HT) patients, the underlying mechanisms remain largely unknown. Given the extensive involvement of protein ubiquitination and deubiquitination in inflammatory diseases, we aimed to investigate how deubiquitinating enzymes regulate thyroid follicular cell pyroptosis and HT pathogenesis. Methods: Our study specifically investigated the role of Ubiquitin-specific peptidase 1 (USP1), a deubiquitinase (DUB), in regulating the inflammasome components NLRP3 and AIM2, which are crucial in pyroptosis. We conducted a series of experiments to elucidate the function of USP1 in promoting pyroptosis associated with inflammasomes and the progression of HT. These experiments involved techniques such as USP1 knockdown or inhibition, measurement of key pyroptosis indicators including caspase-1, caspase-1 p20, and GSDMD-N, and examination of the effects of USP1 abrogation on HT using a mouse model. Furthermore, we explored the impact of USP1 on NLRP3 transcription and its potential interaction with p65 nuclear transportation. Results: Our findings provide compelling evidence indicating that USP1 plays a pivotal role in promoting inflammasome-mediated pyroptosis and HT progression by stabilizing NLRP3 and AIM2 through deubiquitination. Furthermore, we discovered that USP1 modulates the transcription of NLRP3 by facilitating p65 nuclear transportation. Knockdown or inhibition of USP1 resulted in weakened cell pyroptosis, as evidenced by reduced levels of caspase-1 p20 and GSDMD-N, which could be restored upon AIM2 overexpression. Remarkably, USP1 abrogation significantly ameliorated HT in the mice model, likely to that treating mice with pyroptosis inhibitors VX-765 and disulfiram. Conclusions: Our study highlights a regulatory mechanism of USP1 on inflammasome activation and pyroptosis in TFCs during HT pathogenesis. These findings expand our understanding of HT and suggest that inhibiting USP1 may be a potential treatment strategy for managing HT. [ABSTRACT FROM AUTHOR]

Introduction: Hashimoto's thyroiditis is a prevalent autoimmune disease among the population. With the progress in diagnostic and research techniques, it has come to light that Hashimoto's thyroiditis is linked to a higher likelihood of developing other disorders that impact multiple organs and systems. Throughout the course of this disease, individuals may experience an array of complications such as sexual dysfunctions, fertility problems, specific mental disorders, cardiovascular diseases and other autoimmune diseases. Aim of the Study: The primary aim of this study is to explore the potential association between Hashimoto’s thyroiditis and its consequential effects on other physiological systems and organs. Description of the State of Knowledge: Hashimoto's thyroiditis is a complex autoimmune disease characterized by chronic inflammation of the thyroid gland. The pathogenesis of the disease is not yet completely understood. Hashimoto's thyroiditis has been associated with a range of health issues, including sexual dysfunction, fertility problems, psychiatric disorders, cardiovascular diseases, and other autoimmune disorders. Materials and methods: An unsystematic scientific literature review was conducted using specific keywords such as Hashimoto's thyroiditis, fertility problems, thyroid tumor, cardiovascular diseases, and autoimmune diseases. The review was carried out on PubMed, analyzing a total of 54 sources published until 2023. Conclusions: HT's association with psychiatric disorders, fertility issues, thyroid tumors, cardiovascular dysfunction, and comorbid autoimmune conditions underscores its broad clinical impact, necessitating integrated management approaches. Effective management of HT requires collaboration among specialists to ensure early detection, proactive intervention, and patient education, ultimately improving therapeutic outcomes and quality of life.

This editorial published in the journal Frontiers in Endocrinology discusses the advancements in thyroid cancer research, specifically focusing on molecular characterization and prediction models for recurrence. The article emphasizes the importance of accurate molecular and genetic characterization to differentiate between less aggressive and more aggressive thyroid tumors. It also explores the use of biomarkers and prediction models to improve the diagnosis and management of thyroid nodules. The document provides a summary of three studies related to thyroid cancer research, which identify genes associated with recurrence, analyze the genetic landscape of thyroid cancer in Chinese patients, and investigate the shared molecular mechanisms between thyroid cancer and Hashimoto's thyroiditis. These studies contribute to our understanding of thyroid cancer and may lead to personalized treatment options. [Extracted from the article]

Abstract
Objective: Hashimoto’s encephalopathy (HE), a rare immune-mediated disorder, manifests as altered mental state, cognitive and psychological dysfunction, seizures, and myoclonus. Little is known, however, about the neuropsychological profiles of individuals with HE due to the sparse amount of research. This report overviews HE, summarizes findings from available published neuropsychological evaluations, and details neuropsychological examinations of a 57-year-old White woman with a confirmed HE diagnosis evidencing persistent neuropsychological impairment at two discrete timepoints.Method: An extensive literature search was conducted on PubMed and Google Scholar for studies including neuropsychological evaluations of HE cases. Our neuropsychological evaluation included chart review, diagnostic clinical interview, performance-based neurocognitive assessment, and measures of personality and psychopathology.Results: Our assessment revealed a largely subcortical pattern of neurocognitive impairment and impactful neuropsychiatric symptoms that, together, significantly impacted the patient’s quality of life and functional status. The patient’s performance improved during a six-month re-evaluation within the domains of cognition, psychological functioning, and functional independence.Conclusions: This article highlights the complexity and possible long-term sequela of HE. Complex medical history (including autoimmune disorders) and psychiatric presentation at onset may be factors related to longer-term cognitive dysfunction. Neuropsychology and psychology can serve important and unique roles in assessing long-term functioning and response to treatment in such cases. [ABSTRACT FROM AUTHOR]- Published

Background: Numerous observational studies have identified associations between both psoriasis (PsO) and psoriatic arthritis (PsA), and autoimmune diseases (AIDs); however, the causality of these associations remains undetermined. Methods: We conducted a bidirectional two-sample Mendelian Randomization study to identify causal associations and directions between both PsO and PsA and AIDs, such as systemic lupus erythematosus (SLE), Crohn's disease (CD), ulcerative colitis (UC), multiple sclerosis (MS), uveitis, bullous pemphigoid (BP), Hashimoto's thyroiditis (HT), rheumatoid arthritis (RA), vitiligo, and ankylosing spondylitis (AS). The causal inferences were drawn by integrating results from four regression models: Inverse Variance Weighting (IVW), MR-Egger, Weighted Median, and Maximum Likelihood. Furthermore, we performed sensitivity analyses to confirm the reliability of our findings. Results: The results showed that CD [IVW odds ratio (ORIVW), 1.11; 95% confidence interval (CI), 1.06-1.17; P = 8.40E-06], vitiligo (ORIVW, 1.16; 95% CI, 1.05-1.28; P = 2.45E-03) were risk factors for PsO, while BP may reduce the incidence of PsO (ORIVW, 0.91; 95% CI, 0.87-0.96; P = 1.26E-04). CD (ORIVW, 1.07; 95% CI, 1.02-1.12; P = 0.01), HT (ORIVW, 1.23; 95% CI, 1.08-1.40; P = 1.43E-03), RA (ORIVW, 1.11; 95% CI, 1.02-1.21, P = 2.05E-02), AS (ORIVW, 2.18; 95% CI, 1.46-3.27; P = 1.55E-04), SLE (ORIVW, 1.04; 95% CI, 1.01-1.08; P = 1.07E-02) and vitiligo (ORIVW, 1.27; 95% CI, 1.14-1.42; P = 2.67E-05) were risk factors for PsA. Sensitivity analyses had validated the reliability of the results. Conclusions: Our study provides evidence for potential causal relationships between certain AIDs and both PsO and PsA. Specifically, CD and vitiligo may increase the risk of developing PsO, while CD, HT, SLE, RA, AS, and vitiligo may elevate the risk for PsA. Additionally, it is crucial to closely monitor the condition of PsO patients with specific AIDs, as they have a higher likelihood of developing PsA than those without AIDs. Moving forward, greater attention should be paid to PsA and further exploration of other PsO subtypes is warranted. [ABSTRACT FROM AUTHOR]

COVID-19, a global epidemic of infectious disease caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), not only initially refers to acute manifestations but also chronic symptoms known as Long COVID-19. Long COVID-19 represents a significant burden to healthcare systems worldwide. This syndrome encompasses a wide range of continuing health problems with variable durations and consequences for patients' everyday lives. A notable aspect of Long COVID-19 is the emergence of new-onset autoimmune diseases that could be triggered in predisposed patients with altered immune responses. Common autoimmune conditions that arise in post-COVID patients include autoimmune hemolytic anemia, immune thrombocytopenic purpura, autoimmune thyroid diseases, Kawasaki disease, Guillain-Barre syndrome, etc., but with unclear evidence of associated disease occurrence. We present a case of a female rheumatoid arthritis patient who developed autoimmune thyroid disease, latent autoimmune diabetes of adults (LADA), and pernicious anemia after SARS-CoV-2 infection.

Aim This study aimed to demonstrate the role of Epstein-Barr Virus (EBV) in papillary thyroid carcinomas (PTC) developing on the background of Hashimotoʼs thyroiditis (HT). Methods The presence of EBV in tumoral tissue, lymphocytes, and peritumoral normal thyroid tissue was investigated using the in situ hybridization method in paraffin blocks. The subtypes of PTC, tumor diameter, TNM stage, multifocality, invasion of thyroid capsule, perineural invasion, and muscular tissue invasion were identified and compared according to EBV involvement. Results Eighty-one patients with HT diagnosis, with 93.8% (n=76) female and 6.2% (n=5) male, were included in the study. Papillary microcarcinoma was the pathological diagnosis in 24.2% (n=15) of the cases. EBV was identified in 58.06% (n=36) of the tumor cells nuclei, 58.06% (n=36) in the tumor cell cytoplasm, 16.12% (n=10) in tumor infiltrative lymphocytes, and 53.2% (n=33) in normal parenchymal follicle epithelial cells (NPFEC). In the T2 stage, the rate of EBV nuclear positivity in patients was significantly higher (p=0.034). The classic variant of papillary carcinoma was accompanied by a significantly higher rate of EBV-negative NPFEC (67.6%, p=0.049). In multifocal tumors, EBV positivity was found to be significantly higher in lymphocytes in the surrounding tissues (58.3%, p=0.034). Conclusion A significant increase in EBV positivity in the surrounding tissue lymphocytes was observed in multifocal PTC developing on a background of HT. This suggests a possible association between HT and EBV. [ABSTRACT FROM AUTHOR]

Background/Objective: Autoimmune thyroid diseases (AITD) affect 2 to 5% of the general population. This study aimed to determine changes in activity of A-Tg and A-TPO antibodies before, during, and after pregnancy in women with previous AITD. Methods: This was a single-center study with a retrospective review of the medical records of 30 female patients aged 25–41 years who came to our endocrinology service in the city of Santo André, state of São Paulo, Brazil, to investigate thyroid diseases. The following data were reviewed: total triiodothyronine (totalT3), total thyroxine (totalT4), free thyroxine (FT4), thyroid-stimulating hormone (TSH), and anti-TSH receptor antibodies (anti-TSH receptor or anti-thyrotropin receptor antibodies (TRAb), anti-thyroid peroxidase (A-TPO), and anti-thyroglobulin (A-Tg)). These data were reviewed for 30 patients before and during the three trimesters of pregnancy and during the three months after pregnancy. Results: During gestation, we observed a progressive decrease in the blood values of A-TPO and A-Tg, which reached their lowest values in the third trimester of pregnancy, but after birth, they returned to values statistically equivalent to those before pregnancy. Analyzing the three trimesters and the post-pregnancy period, A-TPO increased 192% between the first trimester and postpartum (p = 0.009); it increased 627% between the second trimester and postpartum (p < 0.001); and it increased >1000% between the third trimester and postpartum (p < 0.001). There was no significant difference in the A-TPO values between the pre- and post-gestational periods (p = 1.00), between the first and second trimesters (p = 0.080), or between the second and third trimesters (p = 0.247). Conclusions: According to the results presented here, we observed changes in the activities of A-Tg and A-TPO antibodies during and after pregnancy in women with previous AITD. In women who intend to become pregnant, are pregnant, or have given birth within three months, it is essential to monitor A-TPO, A-Tg, and thyroid function as well as serum thyroid hormones and TSH to identify thyroid dysfunction in a timely manner and adjust the treatment strategy to avoid the deleterious effects of hypothyroidism on both mother and baby during and after pregnancy.

Down‐regulator of transcription 1 (DR1) is considered as a biomarker of hashimoto's thyroiditis (HT), which is a risk factor for thyroid cancer. Here, a label‐free electrochemical biosensor for DR1 detection was constructed based on polyamidoamine (PAMAM) polymer and the nanocomposite (WO3@AuNPs) composed of tungsten trioxide (WO3) and gold nanoparticles (AuNPs). WO3@AuNPs was obtained by combining monolayer WO3 nanosheets, which has high conductivity, and AuNPs. The modification of WO3@AuNPs can not only increase the conductivity of the electrode but also provide more active sites for signaling units, thus greatly improve the sensitivity of the sensor. The polymer PAMAM is biocompatible and non‐immunogenic, and its end functional group can bind to the target molecules, providing them with more binding sites and thus improving the sensitivity of the sensor. Under optimal conditions, the label‐free biosensor showed a good linear relationship between the logarithm of DR1 concentration and the impedance in the range of 10 fg ⋅ mL−1 to 100 ng ⋅ mL−1, with a detection limit as low as 0.3 fg ⋅ mL−1. Besides, this label‐free electrochemical platform exhibited satisfactory selectivity and anti‐interference capability in human serum samples. Therefore, this method has considerable potential in clinical detection of DR1. [ABSTRACT FROM AUTHOR]

Introduction: Hashimoto's thyroiditis (HT) is one of the most common autoimmune endocrine disorders in the pediatric age group. In this study, it was aimed to retrospectively examine our cases, who were children and adolescents diagnosed with HT. Materials and Methods: We retrospectively examined 119 patients between the ages of 1 and 18, who were diagnosed with HT. In all of the cases, physical examination findings, thyroid function tests, anti-thyroid peroxidase (anti-TPO) and antithyroglobulin (Anti-Tg) antibodies, thyroid ultrasonographies and accompanying autoimmune diseases were evaluated. Results: The female/male ratio was 3.5/1. In our cases, the median age at the time of diagnosis was 12.29 years and 10 (8.4%) of the cases were under the age of five. At the time of diagnosis, 37% of the cases were euthyroid, 21.8% had overt hypothyroidism, 34.5% had subclinical hypothyroidism, 2.5% had subclinical hyperthyroidism and 4.2% had overt hyperthyroidism. At the time of diagnosis, 102 cases (85.7%) had anti-TPO and 82 cases (68.9%) had anti-Tg positivity. The Anti-TPO levels at the time of admission were found to be significantly higher in the hypothyroid group compared to the euthyroid group. Conclusion: Thyroid function test results of patients with Hashimoto's thyroiditis may vary in the follow-up period. Even though most cases with euthyroidism remain euthyroid, some might progress to hypothyroidism. Although Hashimoto's thyroiditis is most frequently seen in adolescents, approximately 10% of the cases are under the age of five. Therefore, autoimmune thyroiditis should be considered in hypothyroidism occurring in the early stages of life. [ABSTRACT FROM AUTHOR]

Metformin inhibits the secretory function of overactive anterior pituitary cells, including lactotropes. In women of childbearing age, this effect was absent if they had coexisting autoimmune (Hashimoto) thyroiditis. The current study was aimed at investigating whether autoimmune thyroiditis modulates the impact of metformin on the plasma prolactin concentration in men. This prospective cohort study included two groups of middle-aged or elderly men with drug-induced hyperprolactinemia, namely subjects with concomitant Hashimoto thyroiditis (group A) and subjects with normal thyroid function (group B), who were matched for baseline prolactin concentration and insulin sensitivity. Titers of thyroid peroxidase and thyroglobulin antibodies, levels of C-reactive protein, markers of glucose homeostasis, concentrations of pituitary hormones (prolactin, thyrotropin, gonadotropins, and adrenocorticotropic hormone), free thyroxine, free triiodothyronine, testosterone, and insulin growth factor-1 were measured before and six months after treatment with metformin. Both study groups differed in titers of both antibodies and concentrations of C-reactive protein. The drug reduced the total and monomeric prolactin concentration only in group B, and the impact on prolactin correlated with the improvement in insulin sensitivity and systemic inflammation. There were no differences between the follow-up and baseline levels of the remaining hormones. The results allow us to conclude that autoimmune thyroiditis mitigates the impact of metformin on prolactin secretion in men. [ABSTRACT FROM AUTHOR]

Our study aimed to identify and verify G protein-related methylated genes in AIT patients, while also investigate those genes in AIT patients exposed to iodine in different water iodine areas. Different areas were classified by median water iodine (MWI) concentrations: Iodine-Fortified Areas (IFA, MWI<10µg/L), Iodine-Adequate Areas (IAA, 40≤MWI≤100 µg/L), and Iodine-Excessive Areas (IEA, MWI>100 µg/L). We studied 176 AIT cases and 176 controls, with 89, 40, and 47 pairs in IFA, IAA, and IEA, respectively. Using the Illumina Human Methylation 850k BeadChip, we identified candidate methylated genes. MethylTargetTM and QRT-PCR validated DNA methylation and mRNA expression. Results showed hypomethylation and high expression of RAB8A and RAP1A in all 176 AIT cases. RAB8A's CpG sites were mainly hypomethylated in IFA and IEA, while RAP1A's sites were primarily hypomethylated in IEA. This study underscores how water iodine exposure may influence RAB8A and RAP1A methylation in AIT. [ABSTRACT FROM AUTHOR]

TNF-α-induced protein 3 (TNFAIP3), commonly referred to as A20, is an integral part of the ubiquitin-editing complex that significantly influences immune regulation, apoptosis, and the initiation of diverse immune responses. The A20 protein is characterized by an N-terminal ovarian tumor (OTU) domain and a series of seven zinc finger (ZNF) domains. Mutations in the TNFAIP3 gene are implicated in various immune-related diseases, such as Behçet's disease, polyarticular juvenile idiopathic arthritis, autoimmune thyroiditis, autoimmune hepatitis, and rheumatoid arthritis. These mutations can lead to a spectrum of symptoms, including, but not limited to, recurrent fever, ulcers, rashes, musculoskeletal and gastrointestinal dysfunctions, cardiovascular issues, and respiratory infections. The majority of these mutations are either nonsense (STOP codon) or frameshift mutations, which are typically associated with immune dysfunctions. Nonetheless, missense mutations have also been identified as contributors to these conditions. These genetic alterations may interfere with several biological pathways, notably abnormal NF-κB signaling and dysregulated ubiquitination. Currently, there is no definitive treatment for A20 haploinsufficiency; however, therapeutic strategies can alleviate the symptoms in patients. This review delves into the mutations reported in the TNFAIP3 gene, the clinical progression in affected individuals, potential disease mechanisms, and a brief overview of the available pharmacological interventions for A20 haploinsufficiency. Mandatory genetic testing of the TNFAIP3 gene should be performed in patients diagnosed with autoinflammatory disorders to better understand the genetic underpinnings and guide treatment decisions.

Autoimmune thyroid diseases (AITDs), mainly including Graves' disease (GD) and Hashimoto's thyroiditis (HT), are common autoimmune disorders characterized by abnormal immune responses targeting the thyroid gland. We conducted a bidirectional two-sample MR analysis using the largest dataset of peripheral immune cell phenotypes from Sardinia, and the AITD dataset from the 10th round of the FinnGen and the UK Biobank project. Instrumental variables (IVs) were rigorously selected based on the three assumptions of MR and analyzed using the Wald ratio, inverse-variance weighted (IVW), MR-Egger, and weighted median methods. Additionally, sensitivity analyses were performed using Cochrane's Q, the Egger intercept, the MR-PRESSO, and the leave-one-out (LOO) method to ensure the robustness of the results. The Steiger test was utilized to identify and exclude potential reverse causation. The results showed that 3, 3, and 11 immune cell phenotypes were significantly associated with the risk of AITD. In GD, the proportion of naive CD4-CD8- (DN) T cells in T cells and the proportion of terminally differentiated CD4+T cells in T cells showed the strongest inducing and protective effects, respectively. In HT, lymphocyte count and CD45 on CD4+T cells showed the strongest inducing and protective effects, respectively. In autoimmune hypothyroidism, CD127 CD8+T cell count and terminally differentiated DN T cell count exhibited the strongest inducing and protective effects, respectively. Through MR analysis, our study provides direct genetic evidence of the impact of immune cell traits on AITD risk and lays the groundwork for potential therapeutic and diagnostic target discovery.

Background: Thyroid problems are more common in people with diabetes mellitus, according to several researches. Thyroid dysfunction may have a negative impact on metabolic regulation and increase the risk of cardiovascular illnesses in a situation where they are already predisposed. So, the work aims to evaluate the prevalence of thyroid dysfunction in prediabetic patients and to correlate thyroid abnormalities with cardiovascular risk. Patients and Methods: This case-control study was conducted in an outpatient clinic, Faculty of Medicine, Zagazig University, on 100 cases during the period from March 2023 to September 2023. They were classified into two groups: Group (A): 50 apparently healthy individuals as the control group. Group (B): 50 confirmed prediabetic cases. Results: Group B had significantly higher glycemic parameters and triglyceride (TG) than group A and lower high-density lipoprotein (HDL-c). It was found that the prevalence of thyroid dysfunction in group B was 16% as 8% have a subclinical hypothyroidism (SH), 4% have a goiter, and 4% have Hashimoto's thyroiditis while all controls in group A were normal. Thyroid hormones and antibodies were significantly higher in group B than in group A, P<0.001. Electrocardiogram (ECG) shows 12% of the group (B) have ischemic changes and 4% have sinus tachycardia. Left ventricular ejection fraction (LVEF) was significantly lower in the prediabetic group, P=0.02, and Framingham's score was significantly higher in the prediabetic group, P<0.001. By logistic regression analysis, old age (OR = 3.2, p = 0.003), obesity (OR = 2.4, p = 0.001), HbA1c =6 (OR = 4.6, p = 0.032), and framingham score ((=8) (OR = 4.7, p = 0.001) were risk factors for thyroid dysfunction. Conclusion: Patients with prediabetes have an increased prevalence of thyroid dysfunction mainly SH and they are at higher cardiovascular risk than the normal population. [ABSTRACT FROM AUTHOR]

Key Clinical Message: Primary hyperaldosteronism with type 3 autoimmune polyendocrine syndrome was a rare combination of both hyper‐ and hypoendocrine gland function. Comprehensive treatment including surgery and replacement therapy might be an effective strategy. Primary aldosteronism (PA) is a common cause of secondary hypertension originating from hormones. Type 3 autoimmune polyendocrine syndrome (APS‐3) is characterized by the simultaneous or subsequent occurrence of autoimmune‐mediated endocrine gland damage, except for Addison disease. Here we reported an extremely rare case of a 63‐year‐old woman with PA and APS‐3 who initially presented with hypertension (HT). The APS‐3 of this patient mainly exhibited type 1 diabetes mellitus (T1DM) and Hashimoto's thyroiditis. She underwent the adrenal adenoma resection with a histopathologic diagnosis of adrenal cortical adenoma. After surgery, the HT of this patient was immediately reversed, and the concentration of serum potassium went back to normal. Then, this patient was administered with replacement therapy of insulin and levothyroxine sodium tablets (L‐T4). [ABSTRACT FROM AUTHOR]

Objective: Adjuvant chemotherapy is often indicated in patients diagnosed with early breast cancer (EBC). Among others, weight gain is one of the observed side effects of both chemotherapy and other cancer treatments; however, the mechanism is not well‐described. In this study, we aimed to assess thyroid function before and shortly after the course of chemotherapy for EBC. Methods: This is a prospective cohort study of women diagnosed with EBC. The main outcome was the thyroid function and body weight before and after completing chemotherapy. Secondary outcomes were the presence of thyroid autoantibodies and treatment radiation dosage. We included 72 patients treated with adjuvant chemotherapy, whereas 59 patients also received supraclavicular locoregional radiotherapy. Triple‐negative breast cancer (BC) patients receiving chemoimmunotherapy were excluded. Results: After the chemotherapy, we observed an increase in thyroid‐stimulating hormone (p = 0.03) and a decrease in free‐thyroxine (p = 0.0006), with no significant weight change. The prevalence of autoimmune thyroiditis was low. On average 3 months post‐chemo, we found no statistically significant difference in the thyroid function of women treated versus not treated with supraclavicular locoregional radiotherapy. Conclusions: Although statistically significant changes in thyroid hormones were observed, this study suggests no obvious clinically significant changes in thyroid function in women with early BC after the course of chemotherapy. The decrease in thyroid function was not related to autoimmunity, non‐thyroidal illness, radiotherapy, or high‐dose corticosteroids. Further studies with a longer follow‐up of thyroid function after adjuvant chemotherapy and supraclavicular locoregional radiotherapy are needed. [ABSTRACT FROM AUTHOR]

PSYCHOLOGICAL manifestations of general diseases ,AUTOIMMUNE thyroiditis ,PEOPLE with mental illness ,MENTAL illness ,THYROID gland - Abstract
Hypothyroidism is a prevalent thyroid condition in which the thyroid gland fails to secrete an adequate amount of thyroid hormone into the bloodstream. This condition may develop due to genetic or acquired factors. The most frequent cause of acquired hypothyroidism is chronic autoimmune thyroiditis, also known as Hashimoto's disease. Acquired hypothyroidism is diagnosed when patients present with overt hypothyroidism (also known as clinical hypothyroidism), as they exhibit increased TSH and decreased T
3 and T4 serum levels. This article examines the prevalence of psychiatric disorders among patients diagnosed with acquired hypothyroidism with or without Levothyroxine treatment. We discuss the available evidence indicating that acquired hypothyroidism may be a risk factor for psychiatric disorders, and the effectiveness of thyroid treatment in relieving psychiatric symptoms. Additionally, we provide critical details on thyroid hormone cutoff values reported in the literature, their potential clinical importance, and their correlation with psychiatric symptoms. Finally, we examined the various mechanisms by which acquired hypothyroidism can lead to depression. The high rate of comorbidity between hypothyroidism and psychiatric disorders deserves special attention, indicating the importance of consistent monitoring and timely identification of psychiatric symptoms to prevent disease exacerbation and facilitate therapeutic management. On the other hand, several mechanisms underlie the strong association between depression and acquired hypothyroidism. Deeper research into these mechanisms will allow knowledge of the pathophysiology of depression in patients with acquired hypothyroidism and will provide clues to design more precise therapeutic strategies for these patients.

Autoimmune thyroiditis (Hashimoto's thyroiditis) is the most common autoimmune disease. It most often manifests itself as hypothyroidism but may also present with euthyroidism or even hyperthyroidism. The etiopathogenesis of autoimmune thyroiditis is still unclear. However, in addition to genetic and epigenetic factors, many environmental factors are known to increase the risk of developing AIT. In this review, we aimed to collect and analyze data connected with environmental factors and autoimmune thyroiditis development. Our review indicates iodine intake, vitamin D deficiency, selenium deficiency, viral infections caused by Epstein–Barr Virus (EBV), Human parvovirus B19 (PVB19), Human herpesvirus 6A (HHV-6A) and Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), bacterial infection caused by Helicobacter pylori, microbiome disruption, medications such as interferon-alpha and tyrosine kinase inhibitors, as well as stress, climate, and smoking can influence the risk of the occurrence of autoimmune thyroiditis. Having knowledge of risk factors allows for making changes to one's diet and lifestyle that will reduce the risk of developing the disease and alleviate the course of autoimmune thyroiditis.

Introduction: Automated manual lymphatic drainage therapy (AMLDT) is available for home use in the form of a pneumatic mat of 16 pressurized air channels that inflate and deflate to mimic the stretch and release action of manual lymphatic drainage therapy. Four cases (a patient with complex regional pain syndrome and lymphedema, a healthy patient, a breast cancer survivor with chronic pain, and a patient with a history of abdominal surgery) underwent near-infrared fluorescence lymphatic imaging (NIRFLI) with AMLDT to evaluate the effect of AMLDT on lymphatic pumping and pain. Methods: Each patient received 32-36 injections of 25 µg indocyanine green (ICG) on the anterior and posterior sides of their body and underwent 1 h of NIRFLI to assess the drainage of ICG laden lymph toward regional nodal basins at baseline. Each patient lay supine on the mat for 1 h of AMLDT with NIRFLI to assess lymphatic flow during treatment. A final NIFRFLI assessment was done 30-60 min posttreatment with the patient in the supine and prone position. Patients reported baseline and posttreatment pain using the Visual Analogue Scale. An imager analyzed NIRFLI images using ImageJ (US National Institutes of Health). Using time stamps of the first and last images to determine time lapsed and the number of pulses observed in a timeframe, pulsing frequency (pulses/min) was obtained to assess lymphatic function. Results: All 4 cases completed the NIRFLI and AMLDT without complications; all 3 patients with baseline pain reported reduced pain posttreatment. AMLDT appeared to alter lymphatic contractility, with both increased and decreased pulsing frequencies observed, including in nonaffected limbs. Pulsing frequencies were very heterogeneous among patients and varied within anatomic regions of the same patient. Discussion: This proof-of-concept study suggests that AMLDT may impact lymphatic contractility. Further research on its effect on lymphatic function is warranted. [ABSTRACT FROM AUTHOR]

Background: Lymph node metastasis is the major cause of increased recurrence and death in patients with papillary thyroid carcinoma (PTC). We evaluate the clinicopathologic factors affecting excellent response (ER) in patients with PTC with lymph node metastasis following operation and
131 I ablation therapy. Methods: A total of 423 patients with PTC with lymph node metastasis who underwent thyroidectomy and postoperative131 I ablation therapy were enrolled. The relationship between clinicopathological factors affecting ER achievement was analyzed. Results: Multivariate analysis showed that the foci diameter (=1 cm), unifocal, combination with Hashimoto's thyroiditis (HT), lymph node metastases rate (LR) (=40%), no postoperative lymph node metastasis, low preablative stimulated thyroglobulin (ps-Tg) level (=3.87 ng/mL), and the time of131 I ablation therapy (one time) were positively correlated with the ER achievement [odds ratio (OR): 1.744, 3.114, 3.920, 4.018, 2.074, 9.767, and 49.491, respectively; all p < 0.05]. The receiver operating characteristic (ROC) curves showed that the cutoff values of ps-Tg and LR were 4.625 ng/mL and 50.50%, respectively. The AUC of ROC of ps-Tg and LR for predicting ER achievement was 0.821 and 0.746, respectively. The Tg and the cumulative risk of non-ER elevated with the increase of LR, especially for the high-level ps-Tg (>4.625 ng/mL) group. Conclusion: The foci diameter and number, combination with HT, LR, and ps-Tg level are independent factors for ER. Ps-Tg level and LR are valid predictive factors for the efficacy of131 I therapy in patients with PTC. The predictive value of the cumulative risk of non-ER can be improved by the combination of ps-Tg and LR. [ABSTRACT FROM AUTHOR]- Published

ObjectiveMethodsResultsConclusionsThe hallmarks of Hashimoto’s thyroiditis (HT) include the destruction of thyroid cells by leading to insulin resistance (IR), hypothyroidism, and metabolic abnormalities. Kisspeptin, spexin, and galanin control appetite and body weight (BW) to regulate metabolisms. Here, we sought to determine if galanin, kisspeptin, and spexin are linked to the pathophysiology of HT in euthyroid female individuals.Forty-five women with HT and 45 healthy control women of the same age participated in the current study. The enzyme-linked immunosorbent assay (ELISA) method was used to measure the serum levels of galanin, spexin, and kisspeptin.In comparison to the controls, HT patients had significantly higher levels of kisspeptin (
p < 0.01), galanin (p < 0.01), anti-thyroid peroxidase (anti-TPO) (p < 0.001), anti-thyroglobulin (anti-Tg) (p < 0.001), and body mass index (BMI) (p < 0.05). The two groups were comparable in terms of spexin, free triiodothyronine-3 (fT3), fT4, thyroid-stimulating hormone (TSH) levels, and homeostatic model assessment for insulin resistance (HOMA-IR). Galanin and kisspeptin were seen to have a positive correlation (p < 0.01;r = 0.786).Euthyroid women with HT were found to have higher levels of kisspeptin and galanin. These results imply that kisspeptin and galanin may be linked to the pathogenesis of hypothyroidism, and as a result, we believe that these markers may be beneficial in the early detection and treatment of HT patients.

Introduction: We aimed to comprehensively investigate the causal relationship between 731 immune cell traits and autoimmune thyroiditis (AIT) and to identify and quantify the role of 1400 metabolic traits as potential mediators in between. Methods: Using summary-level data from genome-wide association studies (GWAS) we performed a two-sample bidirectional Mendelian randomization (MR) analysis of genetically predicted AIT and 731 immune cell traits. Furthermore, we used a two-step MR analysis to quantify the proportion of the total effects (that the immune cells exerted on the risk of AIT) mediated by potential metabolites. Results: We identified 24 immune cell traits (with odds ratio (OR) ranging from 1.3166 6 to 0.6323) and 10 metabolic traits (with OR ranging from 1.7954 to 0.6158) to be causally associated with AIT, respectively. Five immune cell traits (including CD38 on IgD+ CD24-, CD28 on CD28+ CD45RA+ CD8br, HLA DR+ CD4+ AC, TD CD4+ %CD4+, and CD8 on EM CD8br) were found to be associated with the risk of AIT, which were partially mediated by metabolites (including glycolithocholate sulfate, 5alpha-androstan-3alpha,17beta-diol disulfate, arachidonoylcholine, X-15486, and kynurenine). The proportion of genetically predicted AIT mediated by the identified metabolites could range from 5.58% to 17.7%. Discussion: Our study identified causal associations between AIT and immune cells which were partially mediated by metabolites, thus providing guidance for future clinical and basic research.

Purpose: Radiolabelled fibroblast activation protein inhibitors (FAPIs) are becoming increasingly important for imaging various tumour diseases. However, it is essential to be aware of potential pitfalls. Here, we investigate FAP expression in the thyroid gland in autoimmune thyroiditis (AIT). Methods: AIT patients with pathological thyroid uptake on [68Ga]Ga-FAPI PET were compared with glucose metabolism on 2-[18F]FDG PET in terms of SUVmax/SUVpeak/SUVmean/tissue-to-background ratio (TBR), and with a healthy control group. Results: Between September 2019 and July 2021, 6 patients presented with a visually increased thyroid uptake and TBR on [68Ga]Ga-FAPI PET. In the retrospective clinical work-up, all patients had known or newly diagnosed AIT. Compared to a matched healthy control group, FAP expression and glucose metabolism were significantly increased ([68Ga]Ga-FAPI (SUVpeak): 7.0 vs. 1.7; p = 0.004/(TBRbloodpool): 6.8 vs. 1.7; p = 0.002; 2-[18F]FDG (SUVpeak): 3.9 vs. 1.4; p = 0.004/(TBRbloodpool): 4.0 vs. 1.2; p = 0.041). However, there was no significant difference in median uptake between [68Ga]Ga-FAPI and 2-[18F]FDG PET (SUVpeak: 7.3 vs. 5.6; p = 0.104). Conclusion: Patients with AIT show higher thyroid uptake on [68Ga]Ga-FAPI and 2-[18F]FDG PET. Incidental thyroid uptake is another pitfall in the interpretation of [68Ga]Ga-FAPI PET and should prompt a clinical work-up. [ABSTRACT FROM AUTHOR]

Background Methods Results Conclusion Hashimoto's thyroiditis (HT) is managed with thyroid hormone replacement to maintain a euthyroid state. A subset of patients have refractory symptoms, which improve with thyroidectomy (TT). There remains a reluctance to proceed with surgery due to perceptions of complications, and limited data availability regarding improvements in quality of life (QoL). This retrospective case control study aims to analyse the outcomes and QoL scores for symptomatic euthyroid HT patients who underwent TT.Thirty euthyroid patients who underwent TT for the management of HT between 2017 and 2022 were identified. An age‐matched control group of patients who underwent TT for symptomatic multinodular goitre (MNG) were randomly selected. Demographics, biochemistry, histology, outcomes, and pre‐ and post‐operative SF‐36 and ThyPRO‐39 scores were compared between groups.There were no surgical complications in the HT group, whilst two MNG patients had complications. There was a similar rate of parathyroid auto‐transplantation in both groups, more glands were transplanted in the HT group. There was a significant difference in pre‐ and post‐operative QoL scores for both groups. Comparison revealed a significant improvement in hyperthyroid symptoms, social life and daily life scores in the HT group. There was a significant difference in pre‐ and post‐operative anti‐TPO, anti‐TG and TSH levels in the HT group.Patients with symptomatic Hashimoto's thyroiditis, despite being euthyroid, may benefit from total thyroidectomy however this remains under‐utilized. This study demonstrated that thyroidectomy was associated with an improvement in validated post‐operative quality of life scores and was not associated with increased complication rates for appropriately selected patients.

Early pregnancy thyroid function assessment in mothers is covered. The benefits of using load-specific reference ranges are well-established. We pondered whether the categorization of maternal thyroid function would change if multiple blood samples obtained early in pregnancy were used. Even though binary classification is a common goal of current disease diagnosis techniques, the data sets are small, and the outcomes are not validated. Most current approaches concentrate on model optimization, focusing less on feature engineering. The suggested method can predict increased protein binding, non-thyroid syndrome (NTIS) (simultaneous non-thyroid disease), autoimmune thyroiditis (compensated hypothyroidism), and Hashimoto’s thyroiditis (primary hypothyroidism). In this paper, we develop an automatic thyroid nodule classification system using a multi-scale vision transformer and image enhancement. Graph equalization is the chosen technique for image enhancement, and in our experiments, we used neural networks with four-layer network nodes. This work presents an enhanced linguistic coverage neuro-fuzzy classifier with chosen features for thyroid disease feature selection diagnosis. The training procedure is optimized, and a multi-scale vision transformer network is employed. Each hop connection in Dense Net now has trainable weight parameters, altering the architecture. Images of thyroid nodules from 508 patients make up the data set for this article. Sets of 80% training and 20% validation and 70% training and 30% validation are created from the data. Simultaneously, we take into account how the number of training iterations, network structure, activation function of network nodes, and other factors affect the classification outcomes. According to the experimental results, the best number of training iterations is 500, the logistic function is the best activation function, and the ideal network structure is 2500-40-2-1. K-fold validation and performance comparison with previous research validate the suggested methodology’s enhanced effectiveness. [ABSTRACT FROM AUTHOR]

Autoimmune thyroid diseases (AITD) such as Graves' disease (GD) or Hashimoto's thyroiditis (HT) are organ-specific diseases that involve complex interactions between distinct components of thyroid tissue. Here, we use spatial transcriptomics to explore the molecular architecture, heterogeneity and location of different cells present in the thyroid tissue, including thyroid follicular cells (TFCs), stromal cells such as fibroblasts, endothelial cells, and thyroid infiltrating lymphocytes. We identify damaged antigen-presenting TFCs with upregulated CD74 and MIF expression in thyroid samples from AITD patients. Furthermore, we discern two main fibroblast subpopulations in the connective tissue including ADIRF
+ myofibroblasts, mainly enriched in GD, and inflammatory fibroblasts, enriched in HT patients. We also demonstrate an increase of fenestrated PLVAP+ vessels in AITD, especially in GD. Our data unveil stromal and thyroid epithelial cell subpopulations that could play a role in the pathogenesis of AITD. Autoimmune thyroid diseases (AITD) are complex conditions involving multiple cellular components of the thyroid tissue. In this study, the authors use spatial transcriptomics data to examine thyroid tissue, identifying distinct subsets of damaged thyroid follicular cells, myofibroblasts and capillaries in AITD.

Introduction: Observational investigations have examined the impact of glucosamine use on the risk of cancer and non-neoplastic diseases. However, the findings from these studies face limitations arising from confounding variables, reverse causation, and conflicting reports. Consequently, the establishment of a causal relationship between habitual glucosamine consumption and the risk of cancer and non-neoplastic diseases necessitates further investigation. Methods: For Mendelian randomization (MR) investigation, we opted to employ single-nucleotide polymorphisms (SNPs) as instruments that exhibit robust associations with habitual glucosamine consumption. We obtained the corresponding effect estimates of these SNPs on the risk of cancer and nonneoplastic diseases by extracting summary data for genetic instruments linked to 49 varied cancer types amounting to 378,284 cases and 533,969 controls, as well as 20 non-neoplastic diseases encompassing 292,270 cases and 842,829 controls. Apart from the primary analysis utilizing inverse-variance weighted MR, we conducted two supplementary approaches to account for potential pleiotropy (MR-Egger and weighted median) and assessed their respective MR estimates. Furthermore, the results of the leave-one-out analysis revealed that there were no outlying instruments. Results: Our results suggest divergence from accepted biological understanding, suggesting that genetically predicted glucosamine utilization may be linked to an increased vulnerability to specific illnesses, as evidenced by increased odds ratios and confidence intervals (95% CI) for diseases, such as malignant neoplasm of the eye and adnexa (2.47 [1.34-4.55]), benign neoplasm of the liver/bile ducts (2.12 [1.32-3.43]), benign neoplasm of the larynx (2.01 [1.36-2.96]), melanoma (1.74 [1.17-2.59]), follicular lymphoma (1.50 [1.06-2.11]), autoimmune thyroiditis (2.47 [1.49-4.08]), and autoimmune hyperthyroidism (1.93 [1.17-3.18]). In contrast to prior observational research, our genetic investigations demonstrate a positive correlation between habitual glucosamine consumption and an elevated risk of sigmoid colon cancer, lung adenocarcinoma, and benign neoplasm of the thyroid gland. Conclusion: Casting doubt on the purported purely beneficial association between glucosamine ingestion and prevention of neoplastic and non-neoplastic diseases, habitual glucosamine ingestion exhibits dichotomous effects on disease outcomes. Endorsing the habitual consumption of glucosamine as a preventative measure against neoplastic and non-neoplastic diseases cannot be supported. [ABSTRACT FROM AUTHOR]

While it is known that immunoglobulin replacement therapy (IgRT) used in the treatment of primary immunodeficiency disorders (PIDs) can lead to the passive transfer of autoantibodies, there is no data indicating that these antibodies can cause clinical symptoms in patients. This study aimed to investigate the presence of autoantibodies and their clinical correlation in patients diagnosed with PIDs receiving IgRT. Paediatric patients who were diagnosed with PIDs, and administered IgRT at our immunology clinic between 1 January 2012 and 31 December 2021, were included in the study. The medical records of these patients were retrospectively analysed, and autoantibodies were screened. Autoantibody screening was conducted at least once in 48 cases. Among these cases, 29 cases (60.4%) demonstrated positivity for at least one of the autoantibodies screened in the study. Among these cases, 23 tested positive for anti‐TPO, 9 for anti‐TG and 2 for both anti‐TPO and anti‐TG. Only two of these patients were confirmed to have Hashimoto's thyroiditis. In 30 cases, autoantibodies related to Celiac disease (CD) were screened, with at least one being positive in five different cases; CD was not confirmed. The results of our study suggest that passive transfer of autoantibodies to patients with IgRT does not cause any significant clinical findings. In addition, in cases of PID, autoantibodies detected in the blood passed to patients with IgRT can lead to misdiagnosis. Screening for autoantibodies in patients with PID undergoing IgRT may not yield accurate results in terms of detecting autoimmune diseases. [ABSTRACT FROM AUTHOR]

Background: The incidence of hypothyroidism following hemithyroidectomy and risk factors associated with its occurrence are not completely understood. This systematic review investigated the incidence and risk factors for hypothyroidism, thyroxine supplementation following hemithyroidectomy as well as the course of post-operative hypothyroidism, including the time to hypothyroidism and incidence of transient hypothyroidism. Methods: Searches were conducted in MEDLINE, EMBASE, Scopus, and Cochrane library for studies reporting the incidence of hypothyroidism or thyroxine supplementation following hemithyroidectomy. Results: Sixty-six studies were eligible for inclusion: 36 reported risk factors, and 27 reported post-operative course of hypothyroidism. Median follow-up was 25.2 months. The pooled incidence of hypothyroidism was 29% (95% CI, 25-34%; P<0.001). Transient hypothyroidism occurred in 34% of patients (95% CI, 21-47%; P<0.001). The pooled incidence of thyroxine supplementation was 23% (95% CI, 19-27%; P<0.001), overt hypothyroidism 4% (95% CI, 2-6%, P<0.001). Risk factors for development of hypothyroidism included pre-operative thyroid stimulating hormone (TSH) (WMD, 0.87; 95% CI, 0.75-0.98; P<0.001), TSH ≥ 2 mIU/L (RR, 2.87; 95% CI, 2.43-3.40; P<0.001), female sex (RR, 1.19; 95% CI, 1.08-1.32; P=0.007), age (WMD, 2.29; 95% CI, 1.20-3.38; P<0.001), right sided hemithyroidectomy (RR, 1.35; 95% CI, 1.10-1.65, P=0.003), the presence of autoantibodies anti-TPO (RR, 1.92; 95% CI, 1.49-2.48; P<0.001), anti-Tg (RR, 1.53; 95% CI, 1.40-1.88; P<0.001), and Hashimoto's thyroiditis (RR, 2.05; 95% CI, 1.57-2.68; P=0.001). Conclusion: A significant number of patients will develop hypothyroidism or require thyroxine following hemithyroidectomy. An awareness of patient risk factors and postoperative thyroid function course will assist in counselling patients on their risk profile and guiding management. [ABSTRACT FROM AUTHOR]

Objective: It is well known that macro-thyroid-stimulating hormone (macro-TSH) could interfere with the detection of TSH. The anti-TSH autoantibody is an essential component of macro-TSH. However, the epidemiological characteristics and the clinical interference of the anti-TSH autoantibody are unclear. Methods: In this study, the radioimmunoprecipitation technique was used to detect the anti-TSH autoantibody. Platforms with different detection mechanisms were applied to measure the TSH in patients with the anti-TSH autoantibody. Polyethylene glycol (PEG) precipitation was used to determine the immunoassay interference. Results: The prevalence of the anti-TSH autoantibody in patients with mild subclinical hypothyroidism (SCH) and autoimmune thyroiditis, but normal thyroid function, was 4.78%. All 10 patients with anti-TSH antibodies had autoimmune diseases, with five of them having significant clinical test interference. Conclusion: The appearance of the anti-TSH antibody is not associated with thyroid autoantibodies. The presence of the anti-TSH autoantibody can interfere with the detection of TSH and can affect clinical diagnosis and treatment. [ABSTRACT FROM AUTHOR]

Objective: Thyroid nodules are observed in 3-7% of the general population, of which 4-8% are detected by palpation and 10-41% by thyroid ultrasonography (USG). In this study, we aimed to make early surgical or follow-up decisions in patients with thyroid atypia of undetermined significance (AUS)/follicular lesion of undetermined significance based on demographic and clinical characteristics, sonographic findings, and laboratory tests. Methods: Patients over the age of 18 years who were diagnosed with AUS and operated between August 2016 and August 2022 were included in the study. Patients under 18 years of age, those with missing data in the hospital automation system, and those with repeat fine-needle aspiration biopsy were excluded from the study. Results: Sonographic features of malignant and benign cases were compared. In malignant cases, the diameter of the dominant nodule was smaller, which was significant in terms of malignancy. Multicentricity, edge irregularity, and presence of cervical lymph nodes on USG and American Thyroid Association high-risk cases were found to be significant regarding malignancy. "Taller than wide (TTW)" appearance on sonographic images of nodules was observed more frequently in malignant cases. Conclusion: In regression analysis with age, gender, dominant nodule diameter, multicentricity, TTW shape, presence of calcification, presence of sonographic cervical lymph node, presence of lymphocytic thyroiditis in the parenchyma in the final pathology, and edge irregularity, the parameters TTW shape, presence of cervical lymph node, and presence of lymphocytic thyroiditis in the parenchyma were significant in favor of malignancy.

Introduction. Celiac disease (CD) is a chronic autoimmune disorder triggered by gluten ingestion in genetically predisposed individuals, presenting with a diverse range of symptoms that extend beyond the gastrointestinal tract. The condition’s systemic nature is evidenced by its extra-digestive manifestations, which can affect various organs including the skin, joints, liver, and nervous system. Methods. This descriptive, retrospective study was conducted at a tertiary care center, focusing on adult patients diagnosed with CD who exhibited extra-digestive symptoms. Data were extracted from medical records of patients admitted between January 1, 2010 and June 30, 2024. Variables included demographic information, primary diagnosis, and associated extra-digestive manifestations. Descriptive statistical methods were employed for data analysis. Results. The sample included 108 patients with CD, the mean age was 43.21 years, with a predominance of females (76.85%). Iron deficiency anemia was the most common extra-digestive manifestation, affecting 20.37% of patients, followed by hypoproteinemia (18.52%) and Hashimoto’s thyroiditis (14.81%). Cooccurrence analysis revealed frequent combinations of conditions, such as anemia with cardiovascular diseases and depressive disorders. Notable associations with neurological conditions like gluten ataxia and peripheral neuropathy were also observed. Conclusion. This study highlights the extensive extra-digestive manifestations of celiac disease, underscoring its systemic impact. The high prevalence of autoimmune conditions such as Hashimoto’s thyroiditis and rheumatoid polyarthritis among CD patients reflects the need for holistic management strategies. Discrepancies between our findings and existing literature, particularly regarding skin and neurological conditions, emphasize the need for further research to better understand these associations and the long-term effects of a gluten-free diet.

Thyroidectomy, a pivotal treatment for various thyroid disorders, has seen its indications evolve, particularly with the 2014 American Thyroid Association (ATA) Guidelines advocating for conservative surgical approaches like lobectomy. This retrospective study analyzes thyroidectomy practices at a high-volume center from January 2014 to December 2023, focusing on patients potentially eligible for lobectomy per ATA guidelines. The inclusion criteria were tumors < 4 cm, indeterminate thyroid nodules, or differentiated thyroid carcinoma with clinically uninvolved lymph nodes (cN0). This study analyzed the proportion of patients undergoing lobectomy versus total thyroidectomy (TT) and the oncological outcomes. Of 357 patients, 243 underwent TT and 114 underwent lobectomy. The prevalence of lobectomies rose markedly, comprising 73.9% of surgeries in 2023. TT patients were predominantly female (83.5%) and had higher rates of autoimmune thyroiditis (67.5%) and malignancy (89.7%). Lobectomy patients had larger nodules and more indeterminate cytology. Among 301 malignant cases, TT was associated with higher lymph node metastasis, but similar recurrence rates, compared to lobectomy. This study underscores a shift towards lobectomy, reflecting adherence to ATA guidelines and suggesting conservative surgery is feasible without compromising outcomes. Further research on long-term outcomes and refined patient selection criteria is needed to optimize surgical approaches. [ABSTRACT FROM AUTHOR]

Summary: A retrospective analysis was conducted using data from the NHANES. Bone mineral density (BMD) was compared in different thyroid-specific autoantibodies groups. Strengths of associations were calculated by using binary logistic regression models. Higher titers of thyroid-specific autoantibodies (TgAb and/or TPOAb) may lead to decreased BMD. Higher prevalence of TgAb and TPOAb significantly associated with fractures in females but not in males. Purpose: Hashimoto's thyroiditis is characterized by elevated thyroid-specific autoantibodies. It is currently believed that osteoporosis is not only a disease with abnormal mineral metabolism but also with immune abnormalities. This study investigated the relationship between thyroid-specific autoantibodies and osteoporosis, including the bone mineral density (BMD) values and fractures. Methods: A retrospective analysis was conducted using data from the National Health and Nutrition Examination Survey (2007–2010). BMD was compared in different thyroid-specific autoantibodies groups. The associations between thyroid-specific autoantibodies and fractures were explored. Strengths of associations were calculated by binary logistic regression models. Candidate variables for binary logistic regression model were selected after screened in univariate analysis (variables with P < 0.05). Results: A total of 3865 study participants were included in this analysis; 224 participants were TgAb positive and 356 were TPOAb positive. A total of 392 participants reported hip, spine or wrist fractures. Participants with higher prevalence of TgAb or TPOAb had lower BMD. In females, significant cigarettes use, higher prevalence of TgAb and TPOAb, and the BMD of the total femur and femoral neck were significantly associated with fractures. Higher prevalence of TPOAb was particularly associated with a higher possibility of hip or spine fractures. In males, significant cigarettes use, 25OHD3, the BMD values of the total femur, femoral neck and total spine were significantly associated with fractures. Conclusion: Higher prevalence of thyroid-specific autoantibodies may lead to decreased BMD. In females, higher prevalence of TgAb and TPOAb significantly associated with fractures and TPOAb especially relating to the fractures of hip and spine. Males patients with vitamin D deficiency or insufficiency associated a higher possibility of fractures. [ABSTRACT FROM AUTHOR]
