Talanta 2024; 277:126329. [PMID: 38815320 DOI: 10.1016/j.talanta.2024.126329] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2024] [Revised: 05/22/2024] [Accepted: 05/25/2024] [Indexed: 06/01/2024]
Abstract
Graves' disease (GD) is considered among the organ autoimmune diseases and is somewhat linked to other autoimmune and secondary diseases. Commonly used detection methods rely on identifying characteristic clinical features and abnormal biochemical markers, but they have certain limitations and may be affected by patient medication. In this study, a desorption separation ionization (DSI) device coupled with a linear ion trap mass spectrometer is introduced for effective detection and screening of urine from GD patients. To enhance the sensitivity of MS analysis, derivatization reagent is utilized as a labeling method. The MS signal is used for metabolic profiling, through which differential metabolites and pathways are identified. Subsequently, processing the acquired spectra with a machine learning algorithm enables successful differentiation of GD patients and healthy individuals. This method is believed to provide versatile and powerful technical support for effective detection on the scene. Notably, this method offers the advantage of achieving early and rapid diagnosis of thyroid-related diseases.

Abstract
The authors describe a case of bilateral diffuse paraneoplastic orbital myositis induced by a stage IA left testicular pure seminoma. The patient presented with findings typical of thyroid-associated orbitopathy (TAO) and was thought to have TAO until discovery of the malignancy. Treatment included an urgent orchiectomy, as well as 7 weeks of therapeutic plasma exchange. This is the fifth reported case of seminoma-associated orbitopathy, and the second to occur while cancer was in the occult phase. Although seminoma-associated orbitopathy is exceedingly rare, it can masquerade as TAO and should be considered in the differential diagnosis of any young male with atypical TAO findings.

Abstract
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.

Abstract
Autoimmune thyroid diseases (AITDs) include a wide spectrum of thyroid diseases affecting more commonly women than men. The most frequent forms are Graves' Disease (GD) and Hashimoto's thyroiditis / Autoimmune Thyroiditis (AIT), but there are also other immunogenic destructive forms of thyroiditis, that is, silent and postpartum thyroiditis. In the last decade, AITDs and other inflammatory thyroid diseases related to anti-tumor molecular drugs are more frequently seen due to the widespread use of tyrosine kinase inhibitors (TKIs) and immune checkpoint inhibitors (ICPIs). Autoimmune thyroiditis related to SARS-CoV-2 infection has been a novel entity in recent years. Graves' Disease and AIT may shift from hyperthyroidism to hypothyroidism, which may complicate the differential diagnosis and further treatment strategy. Moreover, all AITDs may manifest with thyrotoxicosis (a clinical condition marked with high serum levels of thyroid hormones) which has to be distinguished from hyperthyroidism (increased thyroid hormone production and secretion as a result of hyperfunctioning thyroid gland) due to different therapeutic approaches. Nuclear medicine techniques, such as radioiodine uptake (RAIU) and thyroid scintigraphy, using 99mTc- pertechnetate (Na[99mTc]TcO4) or 123-Iodine (Na[123I]I), have a crucial role in the differential diagnosis. Measurement of thyroid antibodies, e.g. thyroid peroxidase antibodies (TPO) and thyrotropin receptor antibodies (TRAb), as well as thyroid ultrasound, are complementary methods in the evaluation of thyroid disorders.

Abstract
PURPOSE To evaluate retrobulbar adipose tissue of patients with active and inactive Graves' orbitopathy (GO) by shear-wave ultrasound elastography (SWE). METHODS Followed-up in our ophthalmology clinic due to GO, 72 eyes of 36 patients and 38 eyes of 19 healthy controls were included in this cross-sectional case-control study. Graves' patients were divided into two subgroups under clinical activity score (CAS): active Graves' orbitopathy (AGO) (CAS ≥ 3) and inactive Graves' orbitopathy (IGO) (CAS < 3). SWE measurement values of retrobulbar adipose tissue of all participants were recorded in meters/second, and the intergroup comparisons were performed. RESULTS Thirty-four eyes of 17 patients in AGO, 38 eyes of 19 patients in IGO, and 38 eyes of 19 participants in the control group were included in the study. Mean values measured from retrobulbar adipose tissue through SWE were 1.00 ± 0.01 m/sec in AGO, 1.16 ± 0.01 m/sec in IGO, and 0.94 ± 0.01 m/sec in the control groups. Even so, the mean SWE value was significantly higher in the IGO group than in the other groups (p < 0.001). Mean SWE values were significantly higher in the AGO group than in the controls (p = 0.008). In the correlation analysis performed, a significant positive correlation was found between SWE and Hertel exophthalmometer measurement values (p = 0.026, r = 0.212), and thyroid-stimulating hormone receptor antibody (TSHR-Ab) levels (p = 0.018, r = 0.224). CONCLUSION We detected SWE values of retrobulbar adipose tissue high in GO, especially in the IGO group. Such a situation, which we associated with the development of fibrosis, may be an indicator of unresponsiveness to immunomodulatory treatments.

Abstract
The purpose of the current investigation was to elucidate what kinds of responsible mechanisms induce elongation of the sclera in myopic eyes. To do this, two-dimensional (2D) cultures of human scleral stromal fibroblasts (HSSFs) obtained from eyes with two different axial length (AL) groups, <26 mm (low AL group, n = 2) and >27 mm (high AL group, n = 3), were subjected to (1) measurements of Seahorse mitochondrial and glycolytic indices to evaluate biological aspects and (2) analysis by RNA sequencing. Extracellular flux analysis revealed that metabolic indices related to mitochondrial and glycolytic functions were higher in the low AL group than in the high AL group, suggesting that metabolic activities of HSSF cells are different depending the degree of AL. Based upon RNA sequencing of these low and high AL groups, the bioinformatic analyses using gene ontology (GO) enrichment analysis and ingenuity pathway analysis (IPA) of differentially expressed genes (DEGs) identified that sterol regulatory element-binding transcription factor 2 (SREBF2) is both a possible upstream regulator and a causal network regulator. Furthermore, SREBF1, insulin-induced gene 1 (INSIG1), and insulin-like growth factor 1 (IGF1) were detected as upstream regulators, and protein tyrosine phosphatase receptor type O (PTPRO) was detected as a causal network regulator. Since those possible regulators were all pivotally involved in lipid metabolisms including fatty acid (FA), triglyceride (TG) and cholesterol (Chol) biosynthesis, the findings reported here indicate that FA, TG and Chol biosynthesis regulation may be responsible mechanisms inducing AL elongation via HSSF.

Sci Rep 2023; 13:21190. [PMID: 38040820 PMCID: PMC10692093 DOI: 10.1038/s41598-023-47228-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2023] [Accepted: 11/10/2023] [Indexed: 12/03/2023] Open
Abstract
Graves' disease is one of the most common causes of hyperthyroidism. Guideline recommendations advocate the intake of thionamides for at least 1 year. If hyperthyroidism persists, subsequent radioiodine-131 treatment (RIT) is a therapeutic option. Thionamides are known to influence intra-thyroidal bio-kinetics of iodine and should therefore be discontinued at least 3 days prior to RIT if possible. However, the required therapeutic activity has to be calculated individually by pre-therapeutic measurement of the uptake prior to RIT [radioiodine-131 uptake test (RIUT)] in Germany according to national guidelines. Therefore, the aim of this study was to quantify the influence of thionamides on intra-therapeutic uptake. A cohort of 829 patients with Graves' disease undergoing RIUT and RIT was analysed. Patients were subdivided into three groups. Group A: patients with carbimazole medication (n = 312), group B: patients with methimazole medication (n = 252) and group C: patients without thionamides (n = 265). Group A and B were further subdivided depending on the reduction of dosage of thionamides. In order to analyse the influence of thionamides, the variance of the determined individual extrapolated maximum intra-thyroidal uptake (EMU) between RIUT and RIT within the single groups and within the subgroups was statistically evaluated. When administering an equal dose of thionamides or no thionamides in RIUT and RIT (groups A1, B1 and C) no significant differences were detected when comparing EMU in RIT to EMU in RIUT (p > 0.05). In the subgroups A2-A4 (reduced dosage of carbimazole prior to RIT) EMU was significantly increased in RIT compared to RIUT [21% for a reduction of 0 to < 10 mg/d (A2), 39% for a reduction of 10-15 mg/d (A3) and 80% for a reduction of > 15 mg/d (A4)]. In the subgroups B2-B4 (reduced dosage of methimazole prior to RIT) EMU was as well significantly increased in RIT compared to RIUT [26% for a reduction of 0 to < 10 mg/d (B2), 36% for a reduction of 10-15 mg/d (B3) and 59% for a reduction of > 15 mg/d (B4)]. A significant dose-dependent increase of EMU in RIT compared to EMU in RIUT in patients discontinuing or reducing thionamides was detected. Therefore, thionamides should be discontinued at least 2 days prior to RIUT in order to achieve the designated target dose more precisely and to minimize radiation exposure of organs at risk.

Abstract
PURPOSE The aim of this study was to investigate the microRNA (miRNA) expression profile in peripheral blood mononuclear cells (PBMC) of thyroid-associated ophthalmopathy (TAO) patients and to explore the molecular mechanisms of MicroRNA-376b (miR-376b) in the pathogenesis of TAO. METHODS PBMCs from TAO patients and healthy controls were analyzed by miRNA microarray to screen for the significantly differentially expressed miRNAs. The miR-376b expression in PBMCs were confirmed by quantitative real-time polymerase chain reaction (qRT-PCR). The downstream target of miR-376b was screened by online bioinformatics, and detected by qRT-PCR and Western blotting. RESULTS Compared with normal controls, 26 miRNAs were significantly different in PBMCs of TAO patients (14 miRNAs were down-regulated and 12 miRNAs were up-regulated). Among them, miR-376b expression was significantly decreased in PBMCs from TAO patients compared to healthy controls. Spearman correlation analysis revealed that miR-376b expression in PBMCs was significantly negatively correlated with free triiodothyronine (FT3), and positively correlated with thyroid-stimulating hormone (TSH). MiR-376b expression was obviously reduced in 6T-CEM cells after triiodothyronine (T3) stimulation compared to controls. MiR-376b mimics significantly decreased hyaluronan synthase 2 (HAS2) protein expression and the mRNA expression of intercellular cell adhesion molecule-1 (ICAM1) and tumor necrosis factor-α (TNF-α) in 6T-CEM cells, whereas miR-376b inhibitors markedly elevated HAS2 protein expression and gene expression of ICAM1 and TNF-α. CONCLUSIONS MiR-376b expression in PBMCs was significantly decreased in PBMCs from TAO patients compared with the healthy controls. MiR-376b, regulated by T3, could modulate the expression of HAS2 and inflammatory factors. We speculate that miR-376b may be involved in the pathogenesis of TAO patients by regulating the expression of HAS2 and inflammatory factors.

Abstract
Introduction Auditory hallucinations are the most common type of hallucinations observed in schizophrenia; however, visual hallucinations are not uncommon. In Graves' disease, depression, hypomania, and psychosis can occur. While the association between Graves' disease and psychosis has been explored, understanding of the specific impact of thyroid dysfunction severity on psychiatric symptom severity is limited. Here, we present a case report of a patient with schizophrenia comorbid with Graves' disease whose psychotic symptoms were impacted by hyperthyroidism. Case The patient was a 32-year-old Japanese woman who presented with auditory and visual hallucinations, agitation, and pressured speech. The patient was diagnosed with schizophrenia comorbid with Graves' disease and thyroid storm. The patient's psychotic symptoms were found to be associated with fluctuations in thyroid hormone levels, and visual hallucinations were observed only during thyroid storms. Treatment involved dexamethasone, potassium iodide, bisoprolol fumarate, and methimazole for thyrotoxicosis, and a blonanserin transdermal patch, paliperidone, and paliperidone palmitate for psychotic symptoms. The patient's auditory and visual hallucinations improved with antipsychotic treatment and decreased thyroid hormone levels. Conclusion This case highlights the importance of monitoring thyroid function in patients with schizophrenia, particularly those with comorbid Graves' disease. The correlation between psychiatric symptoms and thyroid hormone levels was demonstrated on an individual level over time, with symptoms worsening as thyroid hormone levels increased. Additionally, our case suggests that abnormally high thyroid hormone levels may trigger visual hallucinations in individuals with schizophrenia. Further studies are needed to elucidate the underlying mechanisms and potential treatment implications of this association.

[PMID: 37505062 PMCID: PMC10383553 DOI: 10.3390/medicines10070041] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/09/2023] [Revised: 06/26/2023] [Accepted: 07/03/2023] [Indexed: 07/29/2023]
Abstract
BACKGROUND The association between Graves' disease (GD) and serum vitamin D levels has been studied for decades although the results were controversial. Moreover, the difference in vitamin D levels between the different stages of GD is not well studied. Therefore, this study aimed to compare the vitamin D levels between active and remission GD and to investigate the factors affecting vitamin D levels in GD patients. METHODS This cross-sectional study was performed between 1 January to 31 December 2021. The eligible patients were in either the active or remission stage of GD. The demographic and clinical data of the patients willing to participate in the study were collected, as well as their vitamin D levels. Comparisons of continuous parameters between the active and remission groups were performed using the Mann-Whitney U test, while categorical parameters were performed using the Chi-square test. RESULTS 75 patients were diagnosed with GD, with 54.7% in the active stage. The mean vitamin D level was lower in the active GD group than in the remission GD group (28.23 vs. 31.58 ng/mL, respectively, p-value 0.079). The prevalence of vitamin D deficiency (i.e., serum vitamin D level < 20 ng/mL) in the active GD group was 14.6%, and in the remission GD group was 0% (p-value 0.02). Moreover, there was a significant negative correlation between the serum vitamin D level and serum free T4 level (p-value 0.03). CONCLUSIONS In spite of non-significance, patients with active GD had lower mean vitamin D levels compared to those with remission GD. The prevalence of vitamin D deficiency was significantly higher in the active GD patients. Additionally, a negative correlation between serum vitamin D levels and serum free T4 levels was observed in this study.

Am J Ophthalmol 2023; 249:174-182. [PMID: 36690290 PMCID: PMC10767645 DOI: 10.1016/j.ajo.2023.01.020] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2022] [Revised: 01/13/2023] [Accepted: 01/15/2023] [Indexed: 01/22/2023]
Abstract
PURPOSE To describe the association of smoking status with surgical intervention for thyroid eye disease (TED) at the population-level. DESIGN Retrospective cohort study. METHODS This study included all adults (aged ≥18 years) with Graves disease in the Intelligent Research in Sight (IRIS) Registry (January 1, 2013, to December 31, 2020). The primary outcome was surgical intervention for TED, stratified into orbital decompression, strabismus surgery, and eyelid recession surgery. The Kaplan-Meier estimated 5-year cumulative probability for each surgical intervention was calculated. Multivariable Cox regression was used to evaluate the association between smoking status and each surgical intervention, adjusting for age, sex, race, ethnicity, and geographic region. RESULTS This study included 87,774 patients. Median age was 59 years (IQR, 48-68 years); 81% were female patients. Current smokers had a greater 5-year cumulative probability of orbital decompression (3.7% vs 1.9%; P < .001), strabismus surgery (4.6% vs 2.2%; P < .001), and eyelid recession (4.1% vs 2.6%; P < .001) compared to never smokers. After adjusting for demographic factors, current smokers were at greater risk for orbital decompression (hazard ratio [HR], 2.1; 95% CI, 1.8-2.4; P < .001), strabismus surgery (HR, 2.0; 95% CI, 1.8-2.3; P < .001), and eyelid recession (HR, 1.7; 95% CI, 1.5-1.9; P < .001) than never smokers. Former smokers were at higher risk for each type of surgery for TED, albeit at lower levels than current smokers. CONCLUSIONS Smoking was associated with increased risk of surgical intervention for TED in the IRIS Registry. Former smokers were at a lower risk than current smokers, supporting the role of smoking cessation on lowering the burden of surgical disease at the population-level.

Abstract
Cerebral sinus venous thrombosis (CSVT) is a relatively rare acute disorder of cerebral circulation, but it can potentially be associated with serious sequelae and a poor prognosis. The neurological manifestations associated with it are often not adequately taken into consideration given the extreme variability and nuances of its clinical presentation and given the need for radiological methods suitable for this type of diagnosis. CSVT is usually more common in women, but so far there are little data available in the literature on sex-specific characteristics regarding this pathology. CSVT is the result of multiple conditions and is therefore to be considered a multifactorial disease where at least one risk factor is present in over 80% of cases. From the literature, we learn that congenital or acquired prothrombotic states are to be considered extremely associated with the occurrence of an acute episode of CSVT and its recurrences. It is, therefore, necessary to fully know the origins and natural history of CSVT, in order to implement the diagnostic and therapeutic pathways of these neurological manifestations. In this report, we summarize the main causes of CSVT considering the possible influence of gender, bearing in mind that most of the causes listed above are pathological conditions closely linked to the female sex.

Abstract
BACKGROUND The number of recognised distinct autoimmune diseases (AIDs) has progressively increased over the years with more than 100 being reported today. The natural history of AIDs is characterized by progression from latent and subclinical to clinical stages and is associated with the presence of the specific circulating autoantibodies. Once presented, AIDs are generally chronic conditions. AIDs have the tendency to cluster and co-occur in a single patient. Autoimmune thyroid diseases (AITD) are the most prevalent of AIDs in the world population, and about one-third of the AITD patients also present with a non-thyroid AID during their life-span. Furthermore, patient with non-thyroid AIDs often presents with a form of AITD as a concurrent condition. Many of the clusters of AIDs are well characterized as distinctive syndromes, while some are infrequent and only described in case reports. PURPOSE In this review, we describe the wide spectrum of the combinations and the intricate relationships between AITD and the other AIDs, excluding Addison's disease. These combinations are collectively termed type 3 Autoimmune Polyglandular Syndrome (APS-3), also called type 3 Multiple Autoimmune Syndrome (MAS-3), and represent the most frequent APS in the world populations. CONCLUSIONS Numerous associations of AITD with various AIDs could be viewed as if the other AIDs were gravitating like satellites around AITD located in the center of a progressively expanding galaxy of autoimmunity.

Abstract
Background Graves' disease (GD) is an autoimmune disease, with thyrotropin receptor antibodies (TRAbs) being the most important cause in the pathogenesis. The aim of this study is to assess the clinical significance of anti-TPO Abs in GD. Methods A retrospective study was conducted at the Faiha specialized Diabetes, Endocrine, and Metabolism Center (FDEMC) in Basrah during the period between December 2021 and December 2022. A total of 141 patients with GD were involved in this study, and of them, 97 (68.8%) were women. They were divided into two groups: patients with positive and negative anti-TPO Abs groups. Results Positive anti-TPO Abs were seen in 83 patients (58.9%) with GD. Pretreatment-free thyroxine level (ng/dL) was higher in the anti-TPO Abs positive GD patients than in those with negative antibodies (3.7±0.2 versus 3.0±0.2 with a p=0.021). Similarly, higher TRAb titers (IU/ml) at baseline were also seen in patients with positive anti-TPO Abs (9.8±0.7 versus 6.8±0.8) with a p=0.008. Giraffe appearance on thyroid ultrasound was more common in the group with positive anti-TPO Abs as compared to patients with negative anti-TPO Abs: 20 (87.0%) versus 3 (13.0%) with a p=0.005. A higher anti-TPO Abs titer (IU/mL) was associated with a baseline TRAb level of more than 6.4 IU/mL, and giraffe appearance on thyroid ultrasound (206.5±20.0 p-value<0.0001 and 228.0±35.3 p value=0.007, respectively). Conclusion A positive anti-TPO Abs in GD is associated with a high TRAb titer and free T4 level at baseline, as well as a giraffe appearance on thyroid ultrasound.

Abstract
INTRODUCTION This study aims to analyze the relative risks for total thyroidectomies by comparing complication rates for total versus partial thyroidectomy in the pediatric population. METHODS We queried the Kids' Inpatient Database (KID) 1997-2012 for all cases of total (n = 3253) or partial (n = 2380) thyroidectomy. We then designed a propensity score matching model and compared total versus partial thyroidectomy based on surgical complications and outcomes. RESULTS In our cohort, the median age was 16 years and 79% were females. Those treated at a specialty pediatric hospital or pediatric unit in a general hospital comprised 73% of all patients. The most common indications for surgery were malignancy (46%) and goiter (42%). The most common complications were hypocalcemia and nerve injury with an unweighted incidence of 9% (n = 174) and 3% (n = 57) respectively. When compared to partial thyroidectomy, total thyroidectomy was associated with increased rates of postoperative complications. Additionally, the median length of stay was significantly higher for total thyroidectomy patients. CONCLUSIONS This is the largest analysis to date comparing outcomes for total versus partial thyroidectomy in the pediatric population. Surgeons should consider the increased rates of hypocalcemia and nerve injury complications when selecting total compared to partial thyroidectomy in children.

Abstract
INTRODUCTION Total thyroidectomy (TT) has been shown to be a safe and effective treatment for Graves' disease. However, the time course for improvement of symptoms has not been defined. METHODS With an institutional review board approval, we prospectively gathered survey data of all patients (n = 79) undergoing TT for Graves' disease at a single institution from 2019 to 2021. After informed consent was obtained, patients completed surveys preoperatively and at 2 wk followed by monthly postoperative visits/phone calls. Patient demographics and survey results were collected and analyzed. Symptom recovery time was evaluated using Kaplan-Meier analysis. RESULTS A total of 50 patients completed the survey on postoperative follow-up (response rate 63%). Average age was 38 y (range 12-80 y) and 88% of patients were female. The most common preoperative symptoms were fatigue (90%) and heat/cold intolerance (88%). Tremor (median time to resolution: 1 wk; interquartile range [IQR] 1-3), diarrhea (median 1 wk [IQR 1-3]), and palpitations (median 1 wk [IQR 1-3]) resolved the most rapidly followed by eye symptoms (median 3 wk [IQR 1-6]), heat/cold intolerance (median 3 wk [IQR 3-30]), memory deficits (median 3 wk [IQR 1-undefined]), and fatigue (median: 3 wk [IQR 1-14]). There were no significant differences in time to resolution of symptoms by gender or age (less than versus 40 y and older). Those with uncontrolled Graves' had more severe symptoms but no difference in time to resolution from the euthyroid Graves' patients. CONCLUSIONS Many Graves' disease symptoms improve rapidly following TT, with a median time to improvement of less than 1 mo.

Abstract
Two analytical methods based on miniaturized electrochemical sensors, voltammetric and amperometric sensors, have been developed for the determination of 6-methyl-2-thiouracil (MTU) in meat consumption samples (beef liver and foie). A multivariate approach has been considered to optimize the experimental procedure including extraction and electrochemical detection. Under optimal conditions and at a typical working potential of 1.55 V (vs Ag pseudo-reference electrode), response is linear in the range 0 to 20 µg L−1 MTU concentration range. The empirical limit of detection is 0.13 µg L−1, lower than the maximum concentration established by legislation. The electrochemical methods have been used to analyze MTU-spiked meat samples, and recovery values varying between 85 and 95% with coefficients of variation <30%. The analytical methods developed with the miniaturized electrochemical sensors can successfully determine the concentration of MTU in real meat samples with high accuracy, being the results obtained similar to those provided by other methods such as UV-Vis spectrophotometry. Finally, the degree of sustainability of the electrochemical sensors-based developed method has been quantified by means of the Analytical Eco-Scale.

MiR-29a-3p negatively regulates circulating Tfh memory cells in patients with Graves’ disease by targeting ICOS. Immunol Res 2022; 71:173-184.

Abstract
MicroRNAs (miRNAs) are small endogenous noncoding RNAs that regulate genome expression posttranscriptionally and are involved in autoimmune diseases. Previous studies have indicated that follicular helper T (Tfh) cells play a critical role in the pathogenesis of Graves' disease (GD). However, the molecular mechanisms that contribute to circulating Tfh memory cell response in GD patients remain incompletely understood. This study aimed to investigate the role of miRNAs on circulating Tfh memory cells in GD patients. Herein, our data showed that the proportion of circulating Tfh memory cells, the transcript levels of IL-21, and the plasma concentrations of IL-21 were increased in the peripheral blood from GD patients. We also found that inducible co-stimulator (ICOS) expression, an important molecule expressed on Tfh cells, were significantly augmented in the peripheral blood mononuclear cells (PBMCs) from GD patients and positively correlated with the percentage of circulating Tfh memory cells and the transcript levels of IL-21 in GD. Intriguingly, miRNA sequencing screened miR-29a-3p expression was downregulated and inversely correlated with ICOS expression and the frequency of circulating Tfh memory cells in patients with GD. Luciferase assay demonstrated that ICOS was the direct target gene of miR-29a-3p, and miR-29a-3p could inhibit ICOS at both transcriptional and translational levels. Overexpression of miR-29a-3p reduced the proportion of circulating Tfh memory cells. Moreover, miR-29a-3p expression negatively correlated with serum concentrations of TSH receptor antibody (TRAb) in GD patients. Collectively, our results demonstrate that miR-29a-3p emerges as a post-transcriptional brake to limit circulating Tfh memory cell response in GD patients and may be involved in the pathogenesis of GD.

Abstract
BACKGROUND Thyroid-associated ophthalmopathy (TAO) is the most frequent extrathyroidal manifestation of Graves' disease, affecting up to 50% of patients. It has a great impact on quality of life. Rituximab (RTX) is a human/murine chimeric monoclonal antibody that targets the CD20 receptor on B-lymphocytes. Preliminary work has shown that blocking this CD20 receptor with RTX may affect the clinical course of TAO by reducing inflammation and the degree of proptosis. OBJECTIVES: This review update, originally published in 2013, assesses the efficacy and safety of using RTX for the treatment of TAO. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL; 2022, Issue 2), which contains the Cochrane Eyes and Vision Trials Register, Ovid MEDLINE, Ovid Embase, Latin American and Caribbean Health Science Information database (LILACS), the ISRCTN registry, clinicaltrials.gov and the WHO International Clinical Trials Registry Platform (WHO ICTRP). There were no language restrictions in the electronic search for trials. We last searched the electronic databases on 22 February 2022. SELECTION CRITERIA: We included randomised controlled trials (RCTs) of RTX administered by intravenous infusion using any dosage regimen for the treatment of active TAO in adults, compared to placebo or glucocorticoids treatment. DATA COLLECTION AND ANALYSIS: We used standard methodological procedures expected by Cochrane. Two review authors independently scanned titles and abstracts, and screened full-text reports of potentially relevant studies. The outcomes of interest in this review were: clinical activity score (CAS), NOSPECS severity scale, proptosis (mm), palpebral aperture (mm), extraocular motility (degrees or diplopia rating scale), quality of life and adverse effects. MAIN RESULTS We identified two studies that met the inclusion criteria in this updated review. Across both studies, the mean age of participants was 55 years and 77% were women. RTX compared to intravenous methylprednisolone (IVMP) One study, conducted in Italy, compared RTX (n = 15 after one participant withdrew) with IVMP (n = 16) for active TAO (CAS ≥ 3 out of 7 or 4 out of 10). We judged this study to be at low risk of bias in most domains, but it was stopped early because of disease reactivation in the comparator group (5/16 participants). This study provided low-certainty evidence that RTX may result in CAS improvement at 24 weeks compared to IVMP (15/15 versus 12/16 improved by ≥ 2 points; risk ratio (RR) 1.32, 95% confidence interval (CI) 0.98 to 1.78). Only very low-certainty evidence was available for the other outcomes: NOSPECS improvement by 2 or more classes (3/15 versus 3/16; RR 1.07, 95% CI 0.25 to 4.49); proptosis improvement by 2 mm or more (0/15 versus 1/16; RR 0.35, 95% CI 0.02 to 8.08); palpebral aperture improvement by 3 mm or more (2/15 versus 0/16; RR 5.31, 95% CI 0.28 to 102.38); motility improvement by 1 class or more (3/15 versus 3/16; RR 1.07, 95% CI 0.25 to 4.49); and improvement on the Graves' ophthalmopathy QoL scale by at least 6 points for "functioning" (5/14 versus 8/13; RR 0.58, 95% CI 0.25 to 1.32), and "appearance" (9/14 versus 6/13; RR 1.39, 95% CI 0.69 to 2.82). Adverse events were more common in the RTX group (RR 1.39, 95% CI 0.90 to 2.13; low-certainty evidence). Minor adverse effects (mild infusion reactions) were observed in most people receiving RTX at first infusion. Two participants experienced a major infusion reaction, likely cytokine release syndrome. RTX compared to placebo One study, conducted in the USA, enrolled 25 participants with active TAO (CAS ≥ 4 out of 7), comparing RTX (13 participants) to placebo. We judged this study to be at low risk of bias in most domains, but it was stopped early due to recruitment issues. It provided very low-certainty evidence on the following outcomes at 24 weeks: CAS improvement by 2 or more points (4/13 RTX versus 3/12 placebo; RR 1.23, 95% CI 0.34 to 4.40); NOSPECS improvement by 2 or more classes (2/13 versus 2/12; RR 0.92, 95% CI 0.15 to 5.56); proptosis improvement by 2 mm or more (2/13 versus 4/12; RR 0.46, 95% CI 0.10 to 2.08); palpebral aperture median change (0 mm in RTX group, in both eyes separately, versus -0.5 mm and 0.5 mm in placebo group right and left eye, respectively); motility median diplopia score (3 versus 2.5); SF-12 physical component median score (45.9 versus 40.3) and mental component median score (52.8 versus 46.1). More participants in the RTX group experienced adverse effects (8/13 versus 3/12; RR 2.46, 95% CI 0.84 to 7.18). AUTHORS' CONCLUSIONS: There is currently insufficient evidence to support the use of RTX in people with TAO. Future studies investigating RTX in people with active TAO may need to be multi-centre in order to recruit enough participants to make an adequate judgement on the efficacy and safety of this novel therapy.

The impact of the management strategies for patients with subclinical hypothyroidism on long-term clinical outcomes: An umbrella review. PLoS One 2022; 17:e0268070. [PMID: 35587500 PMCID: PMC9119548 DOI: 10.1371/journal.pone.0268070] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2022] [Accepted: 04/21/2022] [Indexed: 11/18/2022] Open
Abstract
AIM This umbrella review summarises and compares synthesised evidence on the impact of subclinical hypothyroidism and its management on long-term clinical outcomes. METHODS We conducted comprehensive searches on MEDLINE, EMBASE, Scopus, Web of Science, Cochrane Database of Systematic Reviews, JBI Evidence Synthesis, the PROSPERO register, Epistemonikos Database and PDQ Evidence from inception to February and July 2021 using keywords on subclinical hypothyroidism, treatment with levothyroxine, monitoring and primary outcomes (all-cause mortality, cardiovascular events, stroke, frailty fractures and quality of life). Only systematic reviews and meta-analyses on adult patient populations were considered. Study selection, data extraction and quality appraisal using AMSTAR-2 were done independently by two reviewers and discrepancies were resolved through discussion. Overlap across the selected reviews was also assessed, followed by a narrative synthesis of findings. RESULTS A total of 763 studies were identified from literature searches; 20 reviews met inclusion criteria. Methodological quality ratings were high (n = 8), moderate (n = 7), and low (n = 5), but no reviews were excluded on this basis. Though there was slight overlap across all reviews, some pairwise comparisons had high corrected covered area scores. Compared to euthyroidism, untreated subclinical hypothyroidism was associated with a higher risk of cardiovascular events or death if Thyroid Stimulating Hormone was above 10mIU/L at baseline. Treatment was associated with a lower risk of death from all causes for patients younger than 70 years and possibly better cognitive and quality of life scores than untreated individuals. Evidence on the risk of strokes and fractures was inconclusive. CONCLUSION In the long term, treatment of subclinical hypothyroidism may be beneficial for some patient groups. However, the findings of this review are negatively impacted by the relative sparseness and poor quality of available evidence. Additional large and adequately powered studies are needed to investigate this topic further. SYSTEMATIC REVIEW REGISTRATION PROSPERO (CRD42021235172).

Abstract
Numerical experiments based on Monte Carlo simulations and clinical CT data are performed to investigate the spatial and spectral characteristics of Cherenkov light emission and the relationship between Cherenkov light intensity and deposited dose in molecular radiotherapy of hyperthyroidism and papillary thyroid carcinoma. It is found that Cherenkov light is emitted mostly in the treatment volume, the spatial distribution of Cherenkov light at the surface of the patient presents high-value regions at locations that depend on the symmetry and location of the treatment volume, and the surface light in the near-infrared spectral region originates from the treatment site. The effect of inter-patient variability in the tissue optical parameters and radioisotope uptake on the linear relationship between the dose absorbed by the treatment volume and Cherenkov light intensity at the surface of the patient is investigated, and measurements of surface light intensity for which this effect is minimal are identified. The use of Cherenkov light measurements at the patient surface for molecular radiation therapy dosimetry is also addressed.

Abstract
Purpose To report the first case of Tocilizumab treatment for progressive pediatric thyroid eye disease (TED) in a 9-year-old female. Observations A 9-year-old female with a history of hyperthyroidism for 4 months presented with bilateral proptosis (more in the right eye) associated with retrobulbar pain, tearing, and conjunctival and caruncular redness. The exophthalmometry reading on presentation was 21mm OD and 17 mm OS. The patient was managed with observation and control of hyperthyroidism in the beginning. However, on a subsequent visit 3 months later it was observed that the symptoms and clinical findings were rapidly worsening. The exophthalmometry reading upon subsequent follow-up was 22 OD and 22 OS. After multidisciplinary team (MDT) discussions it was decided to treat the patient with four doses of 8mg/kg Tocilizumab injection on monthly basis. Notable improvement of proptosis and resolution of pain, conjunctival and caruncular redness was observed. The exophthalmometry reading 4 months after treatment was 20 OD and 19 OS. Conclusion and importance This case report opens an important gateway for the use of Tocilizumab in progressive TED in pediatric age groups.

Abstract
PURPOSE Our understanding of thyroid-associated ophthalmopathy (TAO, A.K.A Graves' orbitopathy, thyroid eye disease) has advanced substantially, since one of us (TJS) wrote the 2010 update on TAO, appearing in this journal. METHODS PubMed was searched for relevant articles. RESULTS Recent insights have resulted from important studies conducted by many different laboratory groups around the World. A clearer understanding of autoimmune diseases in general and TAO specifically emerged from the use of improved research methodologies. Several key concepts have matured over the past decade. Among them, those arising from the refinement of mouse models of TAO, early stage investigation into restoring immune tolerance in Graves' disease, and a hard-won acknowledgement that the insulin-like growth factor-I receptor (IGF-IR) might play a critical role in the development of TAO, stand out as important. The therapeutic inhibition of IGF-IR has blossomed into an effective and safe medical treatment. Teprotumumab, a β-arrestin biased agonist monoclonal antibody inhibitor of IGF-IR has been studied in two multicenter, double-masked, placebo-controlled clinical trials demonstrated both effectiveness and a promising safety profile in moderate-to-severe, active TAO. Those studies led to the approval by the US FDA of teprotumumab, currently marketed as Tepezza for TAO. We have also learned far more about the putative role that CD34+ fibrocytes and their derivatives, CD34+ orbital fibroblasts, play in TAO. CONCLUSION The past decade has been filled with substantial scientific advances that should provide the necessary springboard for continually accelerating discovery over the next 10 years and beyond.

Abstract
Severe neutropenia in newly diagnosed hyperthyroidism is a diagnostic and therapeutic dilemma since antithyroid drugs (ATDs) cannot be started if the absolute neutrophil count (ANC) is <1 x 109/L. We report the case of a patient followed for hyperthyroidism associated with severe neutropenia treated with dexamethasone and ATD. The patient was 51 years old and was hospitalized for hyperthyroidism with a thyroid stimulating hormone (TSH) level <0.005 (0.4-4) mUI/L, T4 at 415 (9.3-17.1) ng/L and T3 at 148 (2-4.4) pg/mL on Graves' disease (GD) confirmed by the TSH receptor antibodies at 38 IU/mL and scintigraphy, associated with neutropenia, with ANC at 0.4 x 109/L. He was put on prednisolone 60 mg/day and propranolol 60 mg/day for three weeks without improvement. Faced with the association of hyperthyroidism and severe neutropenia, we could not start the ATD for fear of agranulocytosis; we put the patient on propranolol 60 mg and dexamethasone 6 mg with progressive degression resulting in a spectacular increase of ANC from 0.4 x 109/L to 7.1 x 109/L, which allowed us to start the ATD (carbimazole) at a dose of 30 mg, and then 50 mg, with monitoring of ANC and transaminases every 48 hours. Euthyroidism was achieved after 15 days. A curative treatment with radioactive iodine ablation was administered. Our patient did not respond to prednisolone but responded dramatically to dexamethasone; this leads us to consider using dexamethasone for the rapid preparation for radical treatment of patients with GD.

Abstract
Graves' disease (GD) is an autoimmune disease caused by antibodies to the thyroid stimulating hormone receptor (TSHR). The FDA-cleared Thyretain™ TSI bioassay is a highly specific method to detect thyroid stimulating antibodies (TSAb/TSI) in the blood of patients with autoimmune thyroid disease (AITD), particularly GD. To simplify the workflow of this bioassay and to support a semi-quantitative result, we have generated a stable CHO-K1 cell line expressing both a chimeric TSH receptor (TSHR-Mc4) and a luciferase-based homogeneous cAMP biosensor (GS luciferase). Here, we describe a rapid, real-time, homogenous bioassay (Turbo™ TSI Bioassay) to directly assess the functional activity of TSI and produce results in International Units of IU/L. The Turbo™ TSI bioassay works by measuring changes in the intracellular cAMP level induced by a G-protein coupled receptor (G-PCR) signaling cascade which is triggered by the binding of TSI to the TSHR. Upon binding to cAMP, the GS luciferase reporter is activated through conformational changes and generates light that can be measured in intact cells with a luminometer. The LoD and LoQ of the assay were determined to be 0.016 IU/L and 0.03 IU/L, respectively and the preliminary assay cutoff was determined to be 0.024 IU/L by ROC analysis using the Thyretain™ TSI bioassay results as reference. The analytical performance of the Turbo™ TSI bioassay is comparable to the Thyretain™ TSI bioassay as evidenced by similar EC50 values for a TSHR stimulating monoclonal antibody (M22). The specificity of the Turbo™ TSI bioassay was demonstrated by showing no response to a high concentration of a human monoclonal TSHR blocking antibody (K1-70). The precision of the assay was excellent with an overall within-laboratory precision <15% CV. When testing 198 clinical samples, the positive and negative percent agreement between the Turbo™ TSI and the Thyretain™ TSI bioassays were 98.7% and 93.5%, respectively. While both bioassays yield equivalent analytical and clinical performances, the Turbo™ TSI bioassay is much simpler to perform. It does not require cell culture, sample dilution, washing or cell lysis steps, resulting in a dramatically reduced turnaround time from about 21 h to 60 min. In addition, the same cell line showed its capability of detecting thyroid blocking antibodies (TBAb/TBI) in a competitive format. The Turbo™ TSI bioassay is user-friendly and is a very promising advancement to aid the diagnosis of autoimmune thyroid disease (AITD).

Abstract
PURPOSE Antithyroid drugs (ATDs) are primarily used as an initial treatment in pediatric patients with Graves' disease (GD). We aimed to investigate the long-term outcomes in pediatric GD patients receiving ATDs. METHODS Retrospective data from a single center were collected from April 2003 to July 2020. A total of 98 children and adolescents aged 2-16 years diagnosed with GD and receiving ATDs was enrolled. We investigated the factors correlated with remission by comparing children who achieved remission after 5 years and those with persistent disease. RESULTS The study included 76 girls (77.6%) and 22 boys (22.4%). During the 5-year follow-up period, 18 children (18.3%) maintained remission, ATDs could not be discontinued in 74 patients (75.5%), and relapse occurred in 6 patients (6.2%). The remission group had significantly lower thyroid-stimulating hormone-binding inhibitory immunoglobulin (TBII) level at diagnosis (P=0.002) and 3 months (P=0.002), 1 year (P=0.002), 2 years (P≤0.001), 3 years (P≤0.001), 4 years (P≤0.001), and 5 years (P≤0.001) after ATD treatment than did the nonremission group. The remission group also had a shorter time for TBII normalization after ATD treatment (P≤0.001). Multiple logistic regression analysis showed that the time to TBII normalization (cutoff time=2.35 years) was related to GD remission (odds ratio, 0.596; 95% confidence interval, 0.374-0.951). CONCLUSION TBII level and time to TBII normalization after ATD treatment can be used to predict remission in pediatric GD patients.

Abstract
BACKGROUND Graves' disease (GD) is one of the most common autoimmune thyroid diseases (AITDs) in humans, and thyrotropin receptor antibody (TRAb) is a characterized autoantibody in GD. The use of radioactive iodine therapy (RAI) for GD treatment is increasing. OBJECTIVES We studied the biological properties of TRAb and evaluated the effect of RAI therapy on TRAb in GD patients. METHODS In total, 225 patients (22 onset GD patients without 131I therapy, 203 GD patients treated with 131I therapy) and 20 healthy individuals as normal controls were included in this study. Clinical assessments were performed, and we examined in vitro the biological properties of TRAb in the 22 onset GD patients and 20 controls as well as 84 GD patients with 131I therapy. RESULTS Serum TRAb and thyroid peroxidase antibody (TPOAb) levels increased in the initial year of RAI treatment, and both antibodies decreased gradually after one year. After 5 years from radioiodine treatment, TRAb and TPOAb levels decreased in 88% and 65% of GD patients, respectively. The proportion of patients positive for thyroid-stimulatory antibody (TSAb) was significantly higher in the 7-12-month group, and thyroid-blocking antibody (TBAb) levels were elevated after one year in half of the patients who received 131I treatment. CONCLUSIONS Treatment of GD patients with radioiodine increased TPOAb and TRAb (their main biological properties were TSAbs) within the first year after therapy, and the main biological properties of elevated TRAb were TBAbs after 1 year.

Abstract
Background Autoimmune thyroid disease (AITD) mainly includes Graves’ disease (GD) and Hashimoto's thyroiditis (HT), which is caused by individual genetics, autoimmune dysfunction, and a variety of external environmental factors. Interleukin (IL)‐38 is involved in a wide range of autoimmune diseases, but little is known about IL‐38 expression in AITD. Methods Fifty patients with GD, 50 with HT, and 50 healthy controls (HC) were enrolled in this study. Basic information of the participants was obtained through a physical examination. Immunological data were obtained by an automatic chemiluminescence immunoanalyzer. C‐reactive protein (CRP) concentrations and the white blood cell count were measured. Serum IL‐38 levels were determined by an enzyme‐linked immunosorbent assay. Results Serum IL‐38 levels were significantly lower in the GD and HT groups than in the HC group (both p < 0.01). Serum CRP concentrations were significantly lower in the HT group than in the HC group (p < 0.05). Receiver operating characteristic curve analysis showed that the area under the curve was 0.7736 (p < 0.01) for IL‐38 and 0.7972 (p < 0.01) for IL‐38 combined with CRP in the GD group. In the HT group, the area under the curve was 0.7276 (p < 0.01) for IL‐38 and 0.7300 for IL‐38 combined with CRP (p < 0.01). Conclusions The results suggest that serum IL‐38 level is a potential new diagnostic biomarker in patients with GD and HT.

Abstract
Background: Vitamin A is a factor that suppresses immune responses, including T helper (Th)1 and Th17 responses. However, there has been no report showing the association between vitamin A-related genes (CYP26B1, RARB, and RARG) and the prognosis of autoimmune thyroid disease (AITD). The objective of this study was to clarify the association between vitamin A-related genes and the susceptibility and prognosis of AITD. Methods: We genotyped polymorphisms in genes encoding vitamin A-related molecules using the polymerase chain reaction-restriction fragment length polymorphism method. The proportion of T helper cells was analyzed by flow cytometry. Serum interleukin (IL)-17 and interferon (IFN)-γ were examined by enzyme-linked immunosorbent assay. Results:CYP26B1 rs3768641 GG genotype and G allele were significantly more frequent in patients with mild Hashimoto's thyroiditis (HT) than in those with severe HT (p = 0.0013 and 0.0024, respectively). The RARB rs1997352 CC genotype was significantly more frequent in HT patients than in controls (p = 0.0207). The proportion of Th17 cells was significantly higher in CYP26B1 rs2241057 TT genotype than C carrier (CC+CT genotypes) (p = 0.0385), in RARB rs1997352 A carrier (AA+AC genotypes) than those with CC genotype (p = 0.0246), and in RARG rs7398676 G carrier (GG+GT genotypes) than in TT genotype (p = 0.0249). In the RARB rs1997352 polymorphism, HT patients with a high concentration of IFN-γ (≥150 ng/mL) were more frequent in the CC genotype than in A carriers (AA+AC genotypes) (p = 0.0226). Serum levels of IL-17 were significantly elevated in subjects with the TT genotype of the CYP26B1 rs2241057 single nucleotide polymorphism (SNP) (p = 0.0026) and in subjects with the GG genotype of the CYP26B1 rs3798641 SNP (p = 0.030). Subjects with a high concentration of IL-17 (≥0.71 pg/mL) were more frequent in RARG 7398676 G carriers (GG+GT genotypes) than in TT genotype (p = 0.0218). Conclusions: Polymorphisms in the CYP26B1 gene were related to the proportion of Th17 cells, the level of IL-17 and the severity of HT. Polymorphisms in RAR were related to the proportion of Th17 cells, concentrations of IFN-γ and IL-17, and susceptibility to HT.

Deiodinase-3 is a thyrostat to regulate podocyte homeostasis. EBioMedicine 2021; 72:103617. [PMID: 34649077 PMCID: PMC8517284 DOI: 10.1016/j.ebiom.2021.103617] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2021] [Revised: 09/22/2021] [Accepted: 09/22/2021] [Indexed: 12/04/2022] Open
Abstract
BACKGROUND Nephrotic syndrome (NS) is associated with kidney podocyte injury and may occur as part of thyroid autoimmunity such as Graves' disease. Therefore, the present study was designed to ascertain if and how podocytes respond to and regulate the input of biologically active thyroid hormone (TH), 3,5,3'-triiodothyronine (T3); and also to decipher the pathophysiological role of type 3 deiodinase (D3), a membrane-bound selenoenzyme that inactivates TH, in kidney disease. METHODS To study D3 function in healthy and injured (PAN, puromycin aminonucleoside and LPS, Lipopolysaccharide-mediated) podocytes, immunofluorescence, qPCR and podocyte-specific D3 knockout mouse were used. Surface plasmon resonance (SPR), co-immunoprecipitation and Proximity Ligation Assay (PLA) were used for the interaction studies. FINDINGS Healthy podocytes expressed D3 as the predominant deiodinase isoform. Upon podocyte injury, levels of Dio3 transcript and D3 protein were dramatically reduced both in vitro and in the LPS mouse model of podocyte damage. D3 was no longer directed to the cell membrane, it accumulated in the Golgi and nucleus instead. Further, depleting D3 from the mouse podocytes resulted in foot process effacement and proteinuria. Treatment of mouse podocytes with T3 phenocopied the absence of D3 and elicited activation of αvβ3 integrin signaling, which led to podocyte injury. We also confirmed presence of an active thyroid stimulating hormone receptor (TSH-R) on mouse podocytes, engagement and activation of which resulted in podocyte injury. INTERPRETATION The study provided a mechanistic insight into how D3-αvβ3 integrin interaction can minimize T3-dependent integrin activation, illustrating how D3 could act as a renoprotective thyrostat in podocytes. Further, injury caused by binding of TSH-R with TSH-R antibody, as found in patients with Graves' disease, explained a plausible link between thyroid disorder and NS. FUNDING This work was supported by American Thyroid Association (ATA-2018-050.R1).

Abstract
PURPOSE In the present study, the authors investigated the effects of selenium on inflammation, hyaluronan production, and oxidative stress in primary cultured orbital fibroblasts of patients with Graves ophthalmopathy (GO). METHODS Orbital adipose/connective tissue specimens were obtained during the course of orbital surgery for patients with GO (n = 7) and other noninflammatory problems (n = 5). After incubation with various concentrations of sodium selenite for 48 hours, supernatants from primary cultures were collected. Hyaluronan and cytokine levels were measured using commercially available enzyme-linked immunosorbent assay kits. To determine the effect of selenium on reactive oxygen species (ROS) production stimulated by H2O2 (100 μM) for 30 minutes, the cells were pretreated with various concentrations of sodium selenite for 60 minutes. RESULTS Interleukin (IL)-6 and tumor necrosis factor-alpha levels were significantly higher in orbital fibroblasts of patients with GO than in orbital fibroblasts of control patients. Hyaluronan production was suppressed by selenium in cultured orbital fibroblasts of patients with GO. Inflammatory cytokines such as IL-1α, IL-8, and tumor necrosis factor-alpha were suppressed by selenium in cultured orbital fibroblasts of patients with GO. IL-1β and IL-6 were not suppressed by selenium in cultured orbital fibroblasts of patients with GO. Selenium pretreatment reduced intracellular ROS generation stimulated by H2O2 in cultured orbital fibroblasts of patients with GO. CONCLUSIONS In conclusion, hyaluronan production, inflammatory cytokines, and intracellular ROS generation were suppressed by selenium in cultured orbital fibroblasts of patients with GO. Several inflammatory cytokines may be suppressed by selenium in cultured orbital fibroblasts of patients with GO. This study provide the basis for use of selenium in the treatment of GO.

Abstract
PURPOSE The first-line antithyroid drug for children and adolescents with Graves' disease (GD) is methimazole (MMI). This study evaluated the relationship between the initial MMI dose and the clinical course of GD after treatment. METHODS We studied the efficacy of the initial MMI dose and the relationship between the initial MMI dose and adverse events (AEs). We retrospectively enrolled 22 males and 77 females and divided those subjects into 3 groups according to the initial dose of MMI: <0.4 mg/kg/day (group A; n=32); 0.4-0.7 mg/kg/day (group B; n=39); and >0.7 mg/kg/day (group C; n=28). RESULTS The mean time to the normalization of free thyroxine (fT4) levels upon initial treatment was 5.64, 8.61, and 7.98 weeks in groups A, B, and C, respectively (P=0.116). The incidence of liver dysfunction, neutropenia, and skin rash was 12.5%, 20.5%, and 42.9% in groups A, B, and C, respectively (P=0.018). Neutropenia, as a severe AE, was absent in group A, but its prevalence was 7.7% in group B and 21.4% in group C (P=0.015). When comparing only groups B and C, the incidences of liver dysfunction and neutropenia were higher in group C (P=0.04 and P=0.021, respectively). CONCLUSION The mean time to the normalization of fT4 levels did not differ among the 3 groups, but the incidence of AEs was higher in the groups that received high MMI doses. High doses of MMI (>0.7 mg/kg/day) should be reconsidered as an initial treatment for children and adolescents with GD.

Abstract
CONTEXT COVID-19, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which has become the most lethal and rapidly moving pandemic since the Spanish influenza of 1918-1920, is associated with thyroid diseases. METHODS References were identified through searches of PubMed and MEDLINE for articles published from Jan 1, 2019 to February 19, 2021 by use of the MeSH terms "hypothyroidism", "hyperthyroidism", "thyroiditis", "thyroid cancer", "thyroid disease", in combination with the terms "coronavirus" and "COVID-19". Articles resulting from these searches and references cited in those articles were reviewed. RESULTS Though preexisting autoimmune thyroid disease appears unlikely to render patients more vulnerable to COVID-19, some reports have documented relapse of Graves' disease (GD) or newly diagnosed GD about 1 month following SARS-CoV-2 infection. Investigations are ongoing to investigate molecular pathways permitting the virus to trigger GD or cause subacute thyroiditis (SAT). While COVID-19 is associated with non-thyroidal illness, it is not clear whether it also increases the risk of developing autoimmune hypothyroidism. The possibility that thyroid dysfunction may also increase susceptibility for COVID-19 infection deserves further investigation. Recent data illustrate the importance of thyroid hormone in protecting the lungs from injury, including that associated with COVID-19. CONCLUSION The interaction between the thyroid gland and COVID-19 is complex and bidirectional. COVID-19 infection is associated with triggering of GD and SAT, and possibly hypothyroidism. Until more is understood regarding the impact of coronavirus on the thyroid gland, it seems advisable to monitor patients with COVID-19 for new thyroid disease or progression of preexisting thyroid disease.

Abstract
PURPOSE This study aimed to evaluate choroidal thickness (CT) and choroidal vascularity index (CVI) in patients with Graves' disease (GD) without ocular involvement. METHODS Fifty patients diagnosed with GD and 50 age and gender matched healthy control subjects were retrospectively evaluated. Measurements were taken from five different points on CT images. Choroid images were classified as lumen regions (LA) and stromal regions (SA) using the image binarization method. CVI was calculated by dividing LA by the total choroidal area (TCA). The effects of Thyrotropin Receptor Antibody (TRAb), age, GD duration, blood pressure, axial length measurements, and intraocular pressure were analyzed on CT and CVI measurements. RESULTS Mean age was 40.1 ± 13.5 years in the patient group and 39.3 ± 13.6 years in the control group (p = 0.89). There was no significant difference between the GD group and control group in terms of CT measurements. There was a significant difference between the mean CVI measurements of the GD group and control group (68.03 ± 3.41 and 66.62 ± 3.11, respectively) (p < 0.001). Univariate linear regression analysis revealed a positive correlation between TRAb and CVI (p = 0.013). CONCLUSION While there was no significant difference between the CT measurements of the GD group and the control group, the GD group had significantly higher CVI measurements.

Cytokine/Chemokine/Growth Factor Profiles Contribute to Understanding the Pathogenesis of the Salivary Gland Dysfunction in Euthyroid Hashimoto's Thyroiditis Patients. Mediators Inflamm 2021; 2021:3192409.

Abstract
Hashimoto's thyroiditis (HT) is one of the most common autoimmune diseases. It is suggested that, in addition to thyroid gland dysfunction, HT is responsible for impaired secretion from the salivary glands. The aim of this study was to evaluate the extent of symptoms of salivary gland dysfunction. We also assessed the relationship between the levels of selected cytokines, chemokines, and growth factors in unstimulated whole saliva (UWS) and the rate of UWS secretion and symptoms of xerostomia in HT patients. The study group consisted of 25 female patients diagnosed with Hashimoto's disease in its spontaneous euthyroid state who had never received hormonal treatment. In more than half of the examined patients, we observed the level of UWS secretion below 0.2 mL/min, indicating impaired secretory function of the salivary glands. Moreover, we demonstrated that the clinical symptoms of salivary gland dysfunction worsen with disease duration. Nevertheless, the inflammatory changes occurring in these glands are independent of general inflammation in the course of HT. Our results clearly indicate an abnormal profile of cytokines, chemokines, and growth factors in the UWS of HT euthyroid women as well as the fact that concentrations of IL-6 and IL-1 as well as INF-γ, TNF-α, and IL-12 may be potential biomarkers for salivary gland dysfunction in the course of HT. Furthermore, salivary IL-12 (p40) may be helpful in assessing the progression of autoimmunity-related inflammation in the course of HT. In conclusion, secretory dysfunction of the salivary glands is closely related to autoimmunity-related inflammation in the course of HT, which leads to objective and subjective symptoms of dry mouth.

Abstract
Thyroid dysfunction is a significant public health issue, affecting 5-10 more women compared to men. The estimated incidence is up to 12% and only for women the treatment rises up to 4.3 billion dollars annually. Thyroid pathology can have a major impact on female fertility and it can only be detected when preconception tests are performed. Untreated or poorly treated hyperthyroidism in a mother can affect the fetal development and pregnancy outcome. Between 0.1 and 0.4% of the pregnancies are affected by clinical hyperthyroidism. Thyroid dysfunction is associated with higher rates of pregnancy loss. Hyperthyroidism can complicate fetal health problems intrauterinely and in the neonatal period. The TSH receptor is stimulated by TSH and HCG which has a similar structure. This can lead to gestational thyrotoxicosis. Hyperthyroidism can be treated with propylthiouracil or methimazole and in selected cases, surgical treatment or radioactive iodine can be chosen. In pregnancy, the most used treatment is represented by propylthiouracil which can be used from the first trimester. The aim of this review is to assess the current data regarding the impact of thyroid dysfunction on pregnancy and to synthesize the treatment options during pregnancy and lactation.

Abstract
AIM Radioiodine therapy (RIT) may trigger the development of Graves' ophthalmopathy (GO) or exacerbate pre-existing subclinical GO. Therefore, glucocorticoid administration is recommended for patients with pre-existing GO. Aim of this study was to analyze the influence of glucocorticoid therapy with methylprednisolone on intratherapeutic effective half-life (EHL) of radioiodine-131 in patients with Graves' disease (GD) as recent studies showed an effect for prednisolone. METHODS In a retrospective study, 264 patients with GD who underwent RIT without any additional antithyroid medication were evaluated. Intrathyroidal EHL was determined pre- and intratherapeutically. Patients with co-existing GO (n = 43) received methylprednisolone according to a fixed scheme starting 1 day prior to RIT, patients without GO (n = 221) did not receive any protective glucocorticoid medication. The ratios of EHL during RIT and during radioiodine uptake test (RIUT) were compared. RESULTS Patients receiving methylprednisolone showed a slight decrease of the mean EHL from 5.63 d (RIUT) to 5.39 d (RIT) (p > 0.05). A comparable result was obtained in patients without glucocorticoids (5.71 d (RIUT) to 5.47 d (RIT); p > 0.05). The ratios of the EHL between RIT and RIUT failed to show a significant difference between the two groups. EHL is therefore not significantly influenced by an additional protective treatment with methylprednisolone. CONCLUSIONS In the present study a decreased intrathyroidal EHL under glucocorticoid medication with methylprednisolone could not be detected. Therefore, co-medication with methylprednisolone in patients with GO may be preferred to avoid an intratherapeutic decrease of EHL by accompanying protective glucocorticoides.

IgG4 as a Biomarker in Graves' Orbitopathy. Mediators Inflamm 2021; 2021:5590471.

Abstract
Immunoglobulin G4-related disease (IgG4-RD) is a chronic inflammatory disorder associated with fibrosis and abundant tissue lymphoplasmacytic infiltrations. It typically affects the pancreas, the salivary glands, and the retroperitoneal space. However, it might also involve multiple other organs, including the orbit and the thyroid. Recent studies have suggested that IgG4 plays a role in the pathophysiology of autoimmune thyroid diseases. This ultimately led to the establishment of new clinical entities called IgG4-related thyroid disease and thyroid disease with an elevation of IgG4. The aim of this paper is to describe the pathophysiological, histopathological, and clinical features of Graves' Disease (GD) and Graves' Orbitopathy (GO) with elevated IgG4 levels. Multiple studies have demonstrated higher IgG4 serum concentrations in GD patients than in healthy euthyroid controls. Depending on the studied population, elevated serum IgG4 levels occur in 6.4-23% (average: 10.3%) of all patients with GD, 8.3-37.5% (average: 17.6%) of patients with GO, and 0-9.8% (average: 5.4%) of patients with GD without GO, while GO patients comprise 37.5-100% (average: 65.8%) of all GD patients with elevated IgG4 levels. Characteristic features of GD with elevated IgG4 levels include lower echogenicity of the thyroid gland on ultrasound examination, peripheral blood eosinophilia, higher prevalence of orbitopathy, and better response to antithyroid drugs with a tendency to develop hypothyroidism when compared to patients with GD and normal levels of IgG4. Typical signs of GO accompanied by increased concentration of IgG4 include younger age at diagnosis, and more severe course of the disease with a higher Clinical Activity Score (CAS).. We strongly recommend considering the diagnosis of GO with elevated IgG4 in patients with an established diagnosis of GD, elevated serum IgG4 levels, and clinical features of ophthalmic disease overlapping with those of IgG4-related orbital disease.

Abstract
Background Graves’ ophthalmopathy (GO) is a disorder, in which orbital connective tissues get in inflammation and increase in volume. Stimulants such as thyroid-stimulating hormone (TSH), insulin-like growth factor 1(IGF-1), IL-1, interferon γ, and platelet-derived growth factor cause differentiation into adipocytes of orbital fibroblasts (OFs) in the orbital fat and extraocular muscles. Human placental mesenchymal stem cells (hPMSCs) are known to have immune modulation effects on disease pathogenesis. Some reports suggest that hPMSCs can elicit therapeutic effects, but to date, research on this has been insufficient. In this study, we constructed PRL-1 overexpressed hPMSCs (hPMSCsPRL-1) in an attempt to enhance the suppressive function of adipogenesis in GO animal models. Methods In order to investigate the anti-adipogenic effects, primary OFs were incubated with differentiation medium for 10 days. After co-culturing with hPMSCsPRL-1, the characteristics of the OFs were analyzed using Nile red stain and quantitative real-time polymerase chain reaction. We then examined the in vivo regulatory effectiveness of hPMSCsPRL-1 in a GO mouse model that immunized by leg muscle electroporation of pTriEx1.1Neo-hTSHR A-subunit plasmid. Human PMSCsPRL-1 injection was performed in left orbit. We also analyzed the anti-adipogenic effects of hPMSCsPRL-1 in the GO model. Results We found that hPMSCsPRL-1 inhibited adipogenic activation factors, specifically PPARγ, C/EBPα, FABP4, SREBP2, and HMGCR, by 75.1%, 50%, 79.6%, 81.8%, and 87%, respectively, compared with naïve hPMSCs in adipogenesis-induced primary OFs from GO. Moreover, hPMSCsPRL-1 more effectively inhibited adipogenic factors ADIPONECTIN and HMGCR by 53.2% and 31.7%, respectively, than hPMSCs, compared with 15.8% and 29.8% using steroids in the orbital fat of the GO animal model. Conclusion Our findings suggest that hPMSCsPRL-1 would restore inflammation and adipogenesis of GO model and demonstrate that they could be applied as a novel treatment for GO patients.

Abstract
Objective Graves' disease (GD) is the main cause of hyperthyroidism among adults. It is an autoimmune condition classically marked by the Merserburg Triad (goiter, thyrotoxicosis, and orbitopathy), but the change in presentation of GD over time has rarely been studied. To determine changes in the clinical presentation of patients with GD in the last 30 years. Methods The study evaluated 475 patients diagnosed with GD between 1986 and 2016 in a single center. Patients were evaluated regarding epidemiological aspects, thyroid function, inflammatory activity of the eyes evaluated by the Clinical Activity Score; CAS, severity evaluated by NOSPECS classification and thyroid volume estimated by ultrasonography. Results Patients assessment identified an increase in the mean age of diagnosis of GD (p < 0.02), a reduction in thyroid volume (p < 0.001) and less intense orbital involvement from 2007-2016 compared to 1986-2006 (p = 0.04). The number of smoking patients was smaller from 2007 to 2016 (28.7%) than 1986 to 2006 (42.8% p = 0.001). The TSH and TRAb values did not had significant changes. Conclusion GD presentation appears to be changed in the last years compared to the typical initial presentation. There is a less frequent inflammatory involvement of orbital tissue, smaller goiters, a lower number of smokers and diagnosis at older age.

Abstract
OBJECTIVE The most common coexisting organ-specific autoimmune disease in patients with type 1 diabetes mellitus (T1DM) is autoimmune thyroid disease (AITD). However, there have been few clinical reports based on a large population about the prevalence of zinc transporter 8 autoantibody (ZnT8A) and other islet autoantibodies in AITD patients. We aimed to explore the presence of islet autoantibodies, ZnT8A, glutamic acid decarboxylase autoantibodies (GADA) and insulinoma-associated antigen 2 autoantibodies (IA-2A) compared with thyroid autoantibodies, thyroid peroxidase autoantibodies (TPOAb) and thyroglobulin autoantibodies (TGAb) and thyrotropin receptor autoantibodies (TRAb) in patients with Graves' disease (GD), Hashimoto's thyroiditis (HT) and T1DM patients with AITD. METHODS Totally, 389 patients with GD, 334 patients with HT, 108 T1DM patients with AITD and 115 healthy controls (HC) were recruited in the study. Islet autoantibodies (ZnT8A, GADA and IA-2A) were detected by radioligand binding assay. Thyroid autoantibodies, TPOAb and TGAb were detected by chemiluminescence assay, and TRAb was detected by RIA. RESULTS The prevalence of ZnT8A, GADA and IA-2A was higher in GD and HT patients than that of HC (ZnT8A: GD 8.48%, HT 10.8% vs HC 1.74%; GADA: GD 7.46%, HT 7.74% vs HC 0.870%; IA-2A: GD 4.88%, HT 3.59% vs HC 0%; All P < 0.05) but lower than that of T1DM subjects with AITD (ZnT8A: 42.6%; IA-2A: 44.4%; GADA: 74.1%; all P < 0.0001). CONCLUSIONS An increased prevalence of ZnT8A as well as GADA and IA-2A was found in both GD and HT patients, indicating that there is a potential link between thyroid autoimmunity and islet autoimmunity.

Comparison of three methods for determining anti-thyrotropin receptor antibodies (TRAb) for diagnosis of Graves' disease: a clinical validation. ADVANCES IN LABORATORY MEDICINE 2021; 2:221-252. [PMID: 37363331 PMCID: PMC10197409 DOI: 10.1515/almed-2021-0015] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 05/21/2020] [Accepted: 07/13/2020] [Indexed: 06/28/2023]
Abstract
Objectives Graves' disease is secondary to the presence of anti-thyrotropin receptor antibodies (TRAb), which stimulate thyroid hormones. TRab determination is crucial for etiological diagnosis. The objectives of this study were (i) to compare two methods for determining TRab by chemoluminiscence vs. standard TRACE-immunofluorescence; (ii) to determine the diagnostic validity of the three methods. Methods A retrospective study in 194 patients with a TRAb determination request. TRAb were determined by immunofluorescence (Kryptor, ThermoFisher) and chemiluminescence (Immulite, Siemens and Maglumi, Snibe). Clinical validation: medical records were reviewed and categorized according to thyroid function. Statistical analysis: Differences in quantitative variables were assessed by intraclass correlation coefficient, Bland-Altman plot, and mean differences (mD). Qualitative variables were dichotomized by cut-off points; Kappa coefficient was calculated. Correlations were evaluated by Pearson's coefficient and Passing-Bablok regression analysis. The diagnostic validity of the three methods was investigated. Results Kryptor-Immulite: mD: 1.2 (95%CI: -16 to >18). Passing-Bablok: Constant error (95%CI: -0.8349 to -0.5987). Proportional error (95%CI: 0.7862-1.0387). ICC: 0.86 (95%CI: 0.82-0.89). Kappa coefficient: 0.68 (95%CI 0.59-0.78). Kryptor-Maglumi: mD: -0.3 (95%CI: -12 to >12). Passing-Bablok: Constant error (95%CI: -0.7701 to >0.1621. Proportional error (95%CI: 0.8571 to 1.3179. ICC: 0.93 (95%CI: 0.89-0.97). Kappa coefficient: 0.53 (95%CI: 0.32-0.74). Diagnosis of Graves' disease was confirmed in 113 patients (Kryptorf showed better specificity and positive predictive value, whereas Immulite demonstrated better sensitivity and negative predictive value). Conclusions The three methods have a good diagnostic performance for Graves' disease, with superimposable results on Bland-Altman plot. Interchangeability was not confirmed on the regression and agreement analysis, with the presence of biases.

Abstract
Background and Objectives: To find the differences in ocular axial length, keratometric measurements, and intraocular lens (IOL) power in patients with Graves’ disease (GD) after treatment with a thionamide antithyroid drug (ATD), methimazole. Materials and Methods: The medical charts of 28 patients (4 males and 24 females; mean age: 47.2 ± 21.2 years) were studied. Each patient was examined twice using an IOL Master Device and keratometry at the first visit (before ATD treatment) and after 1 month of ATD treatment. The IOL power was calculated for each patient using the Hoffer Q, SRK-2, and SRK/T formulas according to axial length. Results: After 1 month, the axial length increased (right and left eyes: p < 0.001 and p = 0.05, respectively). Based on keratometry, changes in the horizontal and vertical optical power [in diopters (D)] were not statistically significant. However, the IOL power changed after 1 month of ATD treatment in 64.3% of the patients. In 14 patients (50%), there was a 0.5–1.0 D IOL power decrease in single eyes; in two patients (7.1%), an IOL power decrease of 0.5–1.0 D in both eyes; and in two patients (7.1%), a 0.5 D IOL power increase in single eyes. The calculated IOL power values were lower after ATD treatment (right and left eyes, p = 0.010 and p = 0.018, respectively). Conclusions: The IOL power changed in 64.3% of GD patients after ATD treatment. Therefore, avoiding cataract surgery at the early stage of ATD treatment would be appropriate for selecting a more accurate IOL power.

Abstract
NEW FINDINGS What is the central question of this study? Do autoantibodies to the M2 muscarinic receptor (M2R-AAbs) have the potential to facilitate specific sustained tachyarrhythmias in the presence of thyroxine (T4 ) in rabbits? What is the main finding and its importance? The M2R-AAb and T4 jointly destabilized the electrophysiological properties, thus promoting the occurrence of atrial and sinus tachyarrhythmias in rabbits. These findings provide a practical basis for understanding the pathophysiological role of M2R-AAb alone and with T4 in arrhythmia induction and might provide an innovative option for treatment of Graves' disease with rhythm disturbance. ABSTRACT Activating autoantibodies toward the β1/2 -adrenergic receptors (β1/2AR-AAbs) and M2 muscarinic receptor (M2R-AAbs) are present in a high proportion of patients with Graves' disease. We previously demonstrated that β1/2AR-AAbs with or without the presence of M2R-AAbs in combination with excessive thyroxine (T4 ) increased the induction of sustained tachyarrhythmias in an autoimmune rabbit model. However, the separate role of M2R-AAbs and their interaction with T4 are not clear. The aim of this study was to investigate the impact of M2R-AAbs and T4 on the induction of cardiac arrhythmias in a similar rabbit model. Ten New Zealand White rabbits were randomly divided into two groups. In group A (n = 6), the rabbits were immunized with the second extracellular loop peptide of M2R and subjected to 2 weeks of T4 treatment. In group B (n = 4), the rabbits were treated only with T4 for 2 weeks. After induction of general anaesthesia, rabbits were subjected to an electrophysiological study at 0 (pre-immune), 6 (post-immune) and 8 weeks (post-immune+T4 treatment) in group A and at 0 (baseline) and 8 weeks (T4 treatment) in group B. Each rabbit served as its own control. In group A, high levels and activity of M2R-AAbs were detected in all immunized animals. Thyroxine in combination with immunization significantly increased induction of sustained sinus tachycardia and atrial fibrillation in comparison to the pre-immune state. In group B, T4 predominantly induced sustained sinus tachycardia. This study demonstrated that M2R-AAbs and T4 jointly increased the susceptibility to both sinus and atrial tachyarrhythmias. The data supported the pathophysiological role of M2R-AAbs in hyperthyroidism-associated supraventricular tachyarrhythmias.

Abstract
PURPOSE Cardiac insufficiency is a major morbidity in neonatal hyperthyroidism. It is important to assess the hemodynamics in neonates born to mothers with Graves' disease (GD). This study prospectively evaluated the hemodynamic changes in neonates born to mothers with GD. METHODS Overall, 80 newborns were enrolled. Thirty-six neonates were born to mothers with GD who were positive for thyroid-stimulating hormone (TSH) receptor antibody (TRAb), and 44 were born to mother negative for TRAb. The serum levels of TSH, free triiodothyronine (FT3), free thyroxine (FT4), and N-terminal-pro-B-type natriuretic peptide (NT-proBNP), the cardiac output, and cardiac index (CI) evaluated by echocardiography were compared between the two groups at several postnatal points (day of delivery and 5, 10, and 30 days of life). RESULTS The TRAb-positive newborns had higher FT4 levels and CI on Day 5 (both p < 0.05) and higher FT3 (p < 0.05) and FT4 levels (p < 0.01) and CI (p < 0.01) but lower TSH levels (p < 0.05) on Day 10 than the TRAb-negative newborns. The TRAb-positive newborns had significantly higher NT-proBNP levels on Days 5 (median 752 vs. 563 pg/mL, p = 0.034) and 10 (median 789 vs. 552 pg/mL, p = 0.002) than the TRAb-negative newborns. CONCLUSIONS Hemodynamic changes in neonates born to TRAb-positive mothers with GD resulted in a higher CI and NT-proBNP levels than in those with TRAb-negative mothers from postnatal days 5 to 10.

Abstract
CONTEXT AND PURPOSE The thyrotropin receptor (TSHR) is the key autoantigen in Graves' disease (GD) and associated orbitopathy (GO). Antibodies targeting the TSHR (TSHR-Ab) impact the pathogenesis and the course of GO. This review discusses the role and clinical relevance of TSHR-Ab in GO. METHODS Review of the current and pertinent literature. RESULTS GO is the most common extrathyroidal manifestation of GD and is caused by persistent, unregulated stimulation of TSHR-expressing orbital target cells (e.g. fibroblasts and pre-adipocytes). Serum TSHR-Ab and more specifically, the stimulatory Ab (TSAb) are observed in the vast majority of patients with GD and GO. TSHR-Ab are a sensitive serological parameter for the differential diagnosis of GO. TSHR-Ab can be detected either with conventional binding immunoassays that measure binding of Ab to the TSHR or with cell-based bioassays that provide information on their functional activity and potency. Knowledge of the biological activity and not simply the presence or absence of TSHR-Ab has relevant clinical implications e.g. predicting de-novo development or exacerbation of pre-existing GO. TSAb are specific biomarkers of GD/GO and responsible for many of its clinical manifestations. TSAb strongly correlate with the clinical activity and clinical severity of GO. Further, the magnitude of TSAb indicates the onset and acuity of sight-threatening GO (optic neuropathy). Baseline serum values of TSAb and especially dilution analysis of TSAb significantly differentiate between thyroidal GD only versus GD + GO. CONCLUSION Measurement of functional TSHR-Ab, especially TSAb, is clinically relevant for the differential diagnosis and management of GO.

Prostaglandin F2α and EP2 agonists, and a ROCK inhibitor modulate the formation of 3D organoids of Grave's orbitopathy related human orbital fibroblasts. Exp Eye Res 2021; 205:108489.

Abstract
3D organoid cultures were used to elucidate the periocular effects of several anti-glaucoma drugs including a prostaglandin F2α analogue (bimatoprost acid; BIM-A), EP2 agonist (omidenepag; OMD) or a Rho-associated coiled-coil containing protein kinase (ROCK) inhibitor (ripasudil; Rip) on Grave's orbitopathy (GO) related orbital fatty tissue. 3D organoids were prepared from GO related human orbital fibroblasts (GHOFs) obtained from patients with GO. The effects of either 100 nM BIM-A, 100 nM OMD or 10 μM Rip on the 3D GHOFs organoids were examined with respect to organoid size, physical properties by a micro-squeezer, and the mRNA expression of extracellular matrix (ECM) proteins including collagen (COL) 1, COL 4, COL 6, and fibronectin (FN), ECM regulatory genes including lysyl oxidase (LOX), Connective Tissue Growth Factor (CTGF) and inflammatory cytokines including interleukin-1β (IL1β) and interleukin-6 (IL6). The size of the 3D GHOFs organoids decreased substantially in the presence of BIM-A, but also increased substantially in the presence of the others (OMD or Rip). The physical stiffness of the 3D GHOFs organoids was significantly decreased by Rip. BIM-A caused significantly the down-regulation of three ECM genes, Col 1, Col 6 and Fn, and two ECM regulatory genes and the up-regulation of IL6. In the presence of OMD, two ECM genes, Col 1 and Fn, and LOX were significantly down-regulated but IL1β and IL6 were significantly up-regulated. In the case of Rip, Col 1, FN and CTGF were significant down-regulated. Our present findings indicate that anti-glaucoma drugs modulate the structures and physical properties 3D GHOFs organoids in different manners by modifying the gene expressions of ECM, ECM regulatory factors and inflammatory cytokines. The results indicate that the benefits and demerits of anti-glaucoma medications need to be scrutinized carefully, in cases of patients with GO.

[PMID: 32519199 DOI: 10.1007/s40618-020-01319-0] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/03/2019] [Accepted: 05/29/2020] [Indexed: 10/24/2022]
Abstract
BACKGROUND Thionamide-induced agranulocytosis (TIA), namely antithyroid drug (ATD)-induced agranulocytosis, is one of the most feared adverse effect of ATDs. It is defined as a granulocyte count of less than 0.5 × 109/L after ATD administration. Several studies reported that TIA is associated with human leukocyte antigen (HLA) and nearby genes. Our previous study found that the susceptibility genes of TIA are similar in north China and European populations. METHODS We evaluated the associations of 23 candidate single nucleotide polymorphisms (SNPs) in 37 patients with TIA and 254 patients with Graves' disease (GD) as controls by iPLEX MassARRAY system. RESULTS Five SNPs in the MHC class I polypeptide-related sequence A(MICA) genes [rs4349859 (p = 1.43E-7); rs145575084 (p = 5.79E-6); rs116135464 (p = 3.70E-5); rs148015908 (p = 3.79E-5) and rs189600525 (p = 2.15E-4)] were found to be significantly associated with TIA after Bonferroni correction. After combining with previous data of rs4349859 and HLA-B*27:05, the haplotype analysis showed that patients carrying P-A-C-A-T-T-A haplotype have a higher risk of TIA (p = 9.76E-7; OR = 14.85, 95% CI 3.63-60.77). CONCLUSION Our findings suggest that five high linked SNPs of MICA gene are significantly associated with susceptibility to TIA.

Abstract
BACKGROUND The thyroid gland influences the metabolic processes in our body by producing thyroid hormones, and thyroid disorders can range from a harmless goiter to life-threatening cancer. A growing number of evidence support the link between gut microbiota composition and thyroid homeostasis. Gut dysbiosis can disrupt the normal gut barrier function, leading to immunologic and metabolic disorders. OBJECTIVE The aim of this review was to discuss the main features of gut dysbiosis associated with different thyroid disorders. RESULTS Gut microbiota contributes to thyroid hormone synthesis and hydrolysis of thyroid hormones conjugates. It has been shown that microbial metabolites may play a role in autoimmune thyroid diseases via modulating the immune system. Intestinal microbiota can contribute to the thyroid malignancies via controlling DNA damage and apoptosis and influencing inflammatory reactions by the microbiota- derived metabolites. However, the pathogenic role of altered gut microbiota in different thyroid disorders has not yet fully elucidated. CONCLUSION Further research is needed to assess the role of alterations of the gut microbiota in disease onset and development in order to achieve novel strategies for the prevention and treatment of these diseases.
