OBJECTIVE: The prevalence and clinical relevance of TSH-receptor (TSHR) blocking antibodies (TBAb) in patients with autoimmune thyroid disease (AITD) was investigated. METHODS: Serum TBAb were measured with a reporter gene bioassay using chinese hamster ovary cells. Blocking activity was defined as percentage inhibition of luciferase expression relative to induction with bovine TSH alone (cut-off 40% inhibition). All samples were measured for TSHR stimulatory Ab (TSAb) and TSHR binding inhibiting immunoglobulins (TBII)...

BACKGROUND: Graves' orbitopathy (GO) is an autoimmune condition, which is associated with poor clinical outcomes including impaired quality of life and socio-economic status. Current evidence suggests that the incidence of GO in Europe may be declining, however data on the prevalence of this disease are sparse. Several clinical variants of GO exist, including euthyroid GO, recently listed as a rare disease in Europe (ORPHA466682). The objective was to estimate the prevalence of GO and its clinical variants in Europe, based on available literature, and to consider whether they may potentially qualify as rare...

A model for human Graves´ disease in mice was used to compare several novel treatment approaches. The mice received regular adenoviral (Ad) thyroid-stimulating receptor (TSHR) A subunit immunisations (4-weekly injections). Generation of anti-TSHR antibodies, enlarged thyroid sizes (goiter), elevated serum thyroxin levels, retro-orbital fibrosis and cardiac involvement (tachycardia and hypertrophy) were consistently observed during 9 months.Treatment of established disease in these mice with novel cyclic peptides which mimic one of the cylindrical loops of the TSHR leucin-rich repeat domain improved or even cured all investigated parameters after 6 consecutive monthly injections...

OBJECTIVE: Graves' orbitopathy (GO) is initiated by excessive amount of various inflammatory mediators produced by orbital fibroblasts. This study aimed to assess the crucial role of sphingosine-1-phosphate (S1P) in the inflammatory process of GO. METHODS: Orbital adipose/connective tissue samples were obtained from 10 GO patients and 10 normal control individuals during surgery. Primary orbital fibroblast culture was done. After the expression of S1P receptors and sphingosine kinase (SphK) was assessed with the treatment of interleukin (IL)-1β, we evaluated the expression of pro-inflammatory factors [intercellular adhesion molecule-1 (ICAM-1), cyclooxygenase-2 (COX-2) and IL-6] after treating S1P...

INTRODUCTION: It is unclear whether the excess mortality associated with Graves' disease differs between individuals with Graves' orbitopathy (GO) or without (GD). SUBJECTS AND METHODS: A nationwide, register-based cohort study in which all adult Danes diagnosed with GD (n = 28 461) and GO (n = 3965) between 1995 and 2012 were matched for age and gender with four control subjects. Median follow-up time was 7.9 years (range 0-17.5). Mortality risk in GO patients compared to the control population and compared to GD patients was calculated using Cox regression analyses, adjusting for pre-existing morbidity using the Charlson score...

Introduction. Selenium is a micronutrient embedded in several proteins. In adults, the thyroid is the organ with the highest amount of selenium per gram of tissue. Selenium levels in the body depend on the characteristics of the population and its diet, geographic area, and soil composition. In the thyroid, selenium is required for the antioxidant function and for the metabolism of thyroid hormones. Methods. We performed a review of the literature on selenium's role in thyroid function using PubMed/MEDLINE...

Graves' orbitopathy (GO), an extrathyroidal manifestation of Graves' disease, is an inflammatory autoimmune disorder of the orbit that involves the differentiation of precursor cells into mature adipocytes and retro-orbital adipose tissue accumulation. Here, we examined the involvement of autophagy in adipogenesis and explored the effects of icariin, a flavonoid isolated from the genus Epimedium with a wide range of biological and pharmacological effects, on autophagy and adipogenesis in 3T3-L1 preadipocytes and in a mouse model of GO...

Graves' orbitopathy (GO) is characterized by orbital T cell infiltration. We evaluated the regulatory T (Treg) cell fractions induced with IGF-1 in Graves' disease (GD) with and without GO. Peripheral blood mononuclear cells (PBMCs) were obtained from 13 patients with GD without eye manifestations; 10 patients with active GO; and 12 patients with nodular goiter (NG). All the patients from GD, GO, and NG were subclinical hyperthyroid. We analyzed the expression of Treg cell markers (CD4, CD25, CD127(-), Foxp3) on T cells and their ability to respond to IGF-1 stimulation...

Management of Graves' orbitopathy remains an important therapeutic challenge. Current therapeutic modalities are unsatisfactory in about one third of patients. Rituximab is a monoclonal antibody against CD20 antigen that is expressed in mature and immature B cells. Early experience with rituximab suggests that it is a promising alternative therapy for Graves' orbitopathy. Here we report a case of a 49-year-old woman with Graves' orbitopathy and psoriasis. The patient received 2 infusions of 1 g rituximab 2 weeks apart...

INTRODUCTION: Early diagnosis and treatment of thyroid eye disease (TED) improves outcomes. Previous studies have highlighted delays in diagnosis and referral to specialist centres. The Amsterdam declaration (2009) aimed to halve the time from presentation to diagnosis and from diagnosis to referral to a specialist centre in five years. A recent study from the European group on Graves' orbitopathy tertiary centres showed a trend for earlier referral of patients to the centres. It is unknown whether similar improvements are occurring in secondary care hospitals in the UK...

PURPOSE: Intravenous glucocorticoids (ivGCs) given as 12-weekly infusions are the first-line treatment for moderate-to-severe and active Graves' orbitopathy (GO), but they are not always effective. In this study, we evaluated whether response at 6 weeks correlated with outcomes at 12 (end of intervention) and 24 (follow-up) weeks, particularly in patients initially unresponsive. METHODS: Our database (Bartalena et al. J Clin Endocrinol Metab 97:4454-4463, 10), comprising 159 patients given three different cumulative doses of methylprednisolone (2...

The success of rituximab for the treatment of active Graves' orbitopathy (GO) suggests that B cells play a critical role in intraorbital inflammation. B cell activating factor (BAFF) and its homolog a proliferation-inducing ligand (APRIL) are critical for B cell survival. However, the contribution of BAFF/APRIL to GO remains unclear. We sought to determine the role of BAFF/APRIL in the orbits of GO, and found that BAFF was markedly upregulated, while APRIL was not. Additionally, cultured GO orbital fibroblasts (GO-OFs)(2) expressing BAFF were induced to produce a large amount of BAFF...

The diagnosis of Graves' orbitopathy is usually straightforward. However, orbital diseases that mimick some clinical signs of Graves' orbitopathy may cause diagnostic confusion, particularly when associated to some form of thyroid dysfunction. This report describes the rare occurrence of localized inferior rectus muscle amyloidosis in a patient with autoimmune hypothyroidism, who was misdiagnosed as Graves' orbitopathy. A 48-year-old man complained of painless progressive proptosis on the left side and intermittent vertical diplopia for 6 months...

INTRODUCTION: Graves' disease (GD) is an autoimmune disorder responsible for 60-90% of thyrotoxicosis, with an incidence of 1 to 2 cases per 1000 population per year in England. Graves' orbitopathy (GO) is the most frequent extrathyroidal manifestation, not provoked directly by abnormal thyroid hormone levels, but by the consequence of the underlying autoimmune process. The aetiology of autoimmune disorders is due to an interplay between susceptibility genes and environmental factors, such as infections and stress...
