Abstract
PURPOSE This perspective introduces the concepts of disease-modulating and -modifying therapy for thyroid eye disease and offers novel metrics for therapeutic outcomes. METHODS A focused literature review was performed. RESULTS Modulators are treatments that suppress disease symptoms whereas modifiers alter the natural history of a disease. Though many drugs are capable of exhibiting both effects, consideration of a drug's primary effect is useful when considering therapeutic options. For thyroid eye disease, corticosteroids and teprotumumab are effective at modulating many signs and symptoms of the disease, particularly those related to soft tissue inflammation. Orbital radiotherapy and rituximab have demonstrated effectiveness at durably modifying the natural history of thyroid eye disease. CONCLUSIONS Outcome metrics should reflect the unique therapeutic objectives associated with disease modulation and modification. This conceptual framework should guide treatment of thyroid eye disease.

Abstract
PURPOSE To summarize the development, nomenclature, and rationale of the reported use of monoclonal antibodies (Mabs) in Graves Orbitopathy (GO) and to undertake a systematic review of the management of GO with Mabs. METHODS The Pubmed and Embase databases and the Federal Brazilian searching site (Periódicos-CAPES) were screened. The authors searched all the keywords "monoclonal antibodies," "adalimumab," "belimumab," "infliximab," "rituximab," "teprotumumab," and "tocilizumab" combined with the terms "Graves Orbitopathy," "Graves eye disease" and "thyroid eye disease." All the articles published in English, French, and Spanish from 2000 to May 2022 were screened. Only publications with quantitative data on the activity of orbitopathy, proptosis, or both were included. RESULTS Seventy-six articles of the 954 screened records met the inclusion criteria. Seven Mabs were described for treating GO. The three most reported Mabs were Rituximab, Tocilizumab, and Teprotumumab. Only eight randomized clinical trials compared the effect of these three Mabs and Belimumab with the effect of steroids or placebos. Adalimumab, Infliximab, and K1-70 only appeared in a few case series and case reports. Frequent mild-to-moderate and few major side effects occurred with the three most used Mabs. Relapse rates ranged from 7.4% for Tocilizumab to at least 29.4% for Teprotumumab. No randomized clinical trials compared Mabs head-to-head. CONCLUSION Considering the lack of head-to-head comparisons between Mabs, the relapse rate, the possibility of severe collateral effects, and the cost of Mabs, it is not clear which Mab is the safest and most useful to treat GO.

Abstract
INTRODUCTION Thyroid eye disease (TED) is an autoimmune disease characterized by inflammation of orbital and extraocular muscles. It induces proptosis and diplopia, leading to a worsening of quality of life (QoL) because of its impact on physical appearance, and visual function. The natural history involves an 'active TED,' which is an autoimmune inflammatory response targeting orbital soft tissues, and 'inactive TED,' where there is tissue expansion remodeling. To date, glucocorticoids represent the main medical therapy, even if often ineffective and associated with side effects. AREAS COVERED In TED, the autoimmune process leads to production of TSH-R and IGF-1 R autoantibodies. This induces inflammatory changes in the orbital tissue, and activation of fibroblasts with accumulation of glycosaminoglycans, leading to consequent proptosis, and diplopia. In two previous randomized, double-masked, placebo-controlled, parallel-group, multicenter trials, teprotumumab has been shown to be effective in improving proptosis, inflammation, diplopia, and QoL. More recently, it has been shown that teprotumumab is also effective in chronic-inactive TED. Teprotumumab was approved by the FDA on 21 January 2020 for the treatment of TED. EXPERT OPINION For the above-mentioned reasons teprotumumab represents a potential first line therapy for TED that could replace the use of steroids in the next future.

Abstract
BACKGROUND AND AIMS This review aims to summarize current and emerging therapies for treatment of thyroid eye disease (TED), in the light of novel understanding of pathogenetic mechanisms, leading to new treatment options and clinical trials. METHODS We reviewed and analyzed peer-reviewed literature reporting recent translational studies and clinical trials in the treatment of TED. Searches were made at www.pubmed.gov with keywords "thyroid eye disease," "Graves' ophthalmopathy," "thyroid orbitopathy," and "Graves' orbitopathy." RESULTS Surgery is reserved for rehabilitation in chronic TED or for emergent compressive optic neuropathy. Oral and intravenous glucocorticoid therapy has been used for decades with variable efficacy in acute TED, but results may be temporary and side effects significant. Nonsteroidal oral immunosuppressive agents offer modest benefit in TED. Several immunomodulatory monoclonal antibodies, including rituximab and tocilizumab, have shown efficacy for inactivating TED. Recently, teprotumumab, an insulin-like growth factor 1 receptor (IGF-1R) inhibitor, has demonstrated significant improvement in proptosis, clinical activity score, diplopia, and quality of life in patients with active TED, with good tolerability. Newly proposed TED therapies, currently in preclinical and clinical trial phases, include thyroid-stimulating hormone (TSH) receptor inhibitory drugs, RVT-1401, local anti-vascular endothelial growth factor therapy, IGF-1R drugs delivered subcutaneously and orally, and desensitization to the TSH receptor with modified TSH receptor peptides. CONCLUSION New, albeit incomplete, understanding of the molecular mechanisms of TED has led to new promising therapies and offered improved outcomes in TED patients. Their full role and their relationship to classical immune suppression should be clarified over the next few years.

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.

Abstract
PURPOSE To describe the efficacy of tocilizumab in the treatment of a cohort of patients with active thyroid-associated orbitopathy. METHODS Patients were identified with active thyroid-associated orbitopathy who were intolerant of or had progression of disease despite systemic corticosteroids and subsequently were treated with tocilizumab between January 2015 and December 2020. Clinical Activity Score, Thyroid-Associated Ophthalmopathy Scale score, and thyroid-stimulating immunoglobulin levels were assessed prior to initiation of tocilizumab, following the first dose, and after the completion of treatment. RESULTS Eleven patients were candidates for and underwent treatment with tocilizumab, 9 of which met criteria for analysis. Average age was 55.6 years. Average time between onset of active thyroid-associated orbitopathy and completion of tocilizumab was 6.5 months. Average number of infusions was 4.2. There was a statistically significant reduction in Clinical Activity Score, Thyroid-Associated Ophthalmopathy Scale score, and thyroid-stimulating immunoglobulin levels when comparing pre-treatment values (mean Clinical Activity Score 6.78 ± 1.09, mean Thyroid-Associated Ophthalmopathy Scale score 10.2 ± 1.92, mean thyroid-stimulating immunoglobulin level 440.6 [%]) to values immediately following completion of treatment (mean Clinical Activity Score 0.44 ± 0.53, mean difference 6.3 points, p < 0.001 [95% CI, 5.5-7.2]; mean Thyroid-Associated Ophthalmopathy Scale score 1.2 ± 1.09, mean difference 9.0 points, p < 0.001 [95% CI, 7.2-10.8]; mean thyroid-stimulating immunoglobulin level 200.7 [%], mean difference 239.9 [%], p = 0.001 [95% CI, 124.3-355.4]). One patient had elevation of cholesterol following therapy induction. Patients were followed for an average of 23.6 months after treatment. No patients had recurrence of active disease after completion of tocilizumab. CONCLUSIONS This study supports the use of tocilizumab as a therapy for the inflammatory phase of thyroid-associated orbitopathy.

Abstract
OBJECTIVE To report the efficacy, long-term safety, and tolerability of using a small dose (125 mg/m2 weekly for 4 weeks) of rituximab to treat Chinese patients with thyroid-associated ophthalmopathy (TAO). METHODS Seven patients with active moderate-to-severe TAO were prospectively recruited in this study. A small dose of rituximab (125mg/m2 body surface area) was given weekly with a duration of four weeks. Thyroid function, thyrotropin receptor antibody (TRAb), B cell and T cell subsets, ophthalmological examination, magnetic resonance imaging derived parameters, and adverse reactions were recorded at each visit. RESULTS Seven patients were followed for an average of 224 weeks. B-cell depletion was observed in all patients following rituximab infusion. The clinical activity score (CAS) decreased from 4.86 ± 0.69 to 3.00 ± 0.82 at 5 weeks after treatment (P = 0.033) and remained significantly lower than baseline values at the end of follow-up (P = 0.001). Compared to baseline values, significant decreases in exophthalmos of the right eye, the thickness of extraocular muscles with maximum signal intensity, and the highest signal intensity ratio (SIR) of extraocular muscle to ipsilateral temporal muscle values were observed at the last follow-up (all P < 0.05). Disease progressions or recurrences were not observed during follow-up. Only mild fatigue was observed after the first infusion as a side effect (n = 1). CONCLUSION Small dose of rituximab may be a promising option with adequate safety, tolerability, and long-term efficacy for patients with active moderate-to-severe TAO.

[PMID: 33783712 DOI: 10.1007/s42000-021-00282-6] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/22/2020] [Accepted: 03/14/2021] [Indexed: 01/03/2023]
Abstract
AIM The successful treatment of Graves' ophthalmopathy (GO) remains a challenge, while the efficacy of rituximab (RTX) is at present controversial. The aim of this meta-analysis was to investigate the potential impact of intravenous RTX therapy in patients with GO. METHODS We performed a search in the PubMed, Embase, and Web of Science databases for relevant studies published before July 2020. The primary outcome was the change of clinical activity score (CAS), and secondary outcomes were the change of proptosis and TSH receptor antibodies (TRAb). A meta-analysis was conducted to calculate the standard mean difference (SMD) for these outcomes by using fixed- or random-effect models. RESULTS Analysis of outcomes in 152 patients collected from 12 published articles was conducted. Compared to baseline value, CAS was significantly decreased at 1, 6, 12, and >12 months after RTX treatment. For proptosis, the results revealed no significant decrease at 1-3, 6, and ≥12 months. Moreover, the pooled analysis employed in this meta-analysis showed no significant difference of TRAb at 1 month, but significant declines were observed at 6 and ≥12 months. CONCLUSION Our results strongly suggest that intravenous RTX treatment has an acute and long-lasting beneficial effect on decreasing both CAS and TRAb. The study also indicates that the effect of RTX on proptosis is limited. There is evidently a need to investigate the mechanism behind RTX ineffectiveness on proptosis and explore other therapeutic regimens for the reduction of proptosis.

Abstract
Teprotumumab, a monoclonal antibody targeted against the insulin-like growth factor 1 (IGF-1) receptor, was recently approved by the United States Food and Drug Administration for the treatment of thyroid eye disease (TED). Phase 1 studies of teprotumumab for the treatment of malignancies demonstrated an acceptable safety profile but limited effectiveness. Basic research implicating the IGF-1 receptor on the CD-34+ orbital fibrocyte in the pathogenesis of TED renewed interest in the drug. Two multicenter, randomized, double-masked, clinical trials (phase 2 and 3) evaluated the efficacy of 8 infusions of teprotumumab every 3 weeks versus placebo in 170 patients with recent-onset active TED, as defined by a clinical activity score (CAS) of at least 4. Teprotumumab was superior to placebo for the primary efficacy end points in both studies: overall responder rate as defined by a reduction of 2 or more CAS points and a reduction of 2 mm or more in proptosis (69% vs. 20%; P < 0.001; phase 2 study) and proptosis responder rate as defined by a reduction of 2 mm or more in proptosis (83% vs. 10%; P < 0.001; phase 3 study). In both studies, treatment with teprotumumab compared with placebo achieved a significant mean reduction of proptosis (-3.0 mm vs. -0.3 mm, phase 2 study; -3.32 mm vs. -0.53 mm, phase 3 study) and CAS (-4.0 vs. -2.5, phase 2 study; -3.7 vs. -2.0, phase 3 study). Teprotumumab also resulted in a greater proportion of patients with a final CAS of 0 or 1, higher diplopia responder rate, and a larger improvement in the Graves' Ophthalmopathy Quality of Life overall score. More than half of patients (62%, phase 2 trial; 56%, phase 3 trial) who were primary end point responders maintained this response at 51 weeks after the last dose of therapy. The most common adverse events reported with teprotumumab included muscle spasms (25%), nausea (17%), alopecia (13%), diarrhea (13%), fatigue (10%), hearing impairment (10%), and hyperglycemia (8%). Teprotumumab is contraindicated for those with inflammatory bowel disease and who are pregnant. Although the current dosing regimen has proven effective for TED, dose-ranging studies including variable concentrations, infusion frequencies, and durations of teprotumumab therapy in the setting of TED have not been performed.

Abstract
Purpose To present a case of ulcerative colitis associated with teprotumumab treatment for thyroid eye disease. Observations A 46-year-old Indian female was treated with teprotumumab (Tepezza) for severe thyroid eye disease within 9 months of diagnosis. The patient noted progression of her disease on oral prednisone and demonstrated severe, debilitating proptosis accompanied by eye ache and dry eyes. After 5 infusions of teprotumumab over a four-month period, the patient developed bloody diarrhea and fecal urgency. These symptoms progressively worsened and after two additional treatments, she underwent a colonoscopy. This confirmed the diagnosis of ulcerative colitis (UC). Treatment with teprotumumab was halted prior to the administration of the 8th infusion; however, the patient continued to have severe gastrointestinal symptoms two months after her last treatment. Conclusions and importance Teprotumumab is an insulin-like growth factor-1 receptor (IGF-1R) inhibitor demonstrated to improve proptosis in patients with active thyroid eye disease. Most adverse events reported are mild or moderate in severity; however, inflammatory bowel disease (IBD) is a serious adverse event that can develop as a result of treatment.

Abstract
Thyroid eye disease (TED) is a debilitating, vision threatening disease that dramatically alters patients' quality of life. Until recently, the management of TED is a long arduous course with supportive therapy, followed by an extensive surgical treatment plan to reverse the disease endpoints. Teprotumumab offers an early, safe therapeutic intervention to help reverse disease end points such as diplopia and proptosis and improve quality of life.

Abstract
Graves' hyperthyroidism is characterized by the presence of autoantibodies that stimulate the thyroid-stimulating hormone receptor (TSHR), resulting in uncontrolled secretion of excessive thyroid hormone. Conventional treatments, including antithyroid medication, radioiodine, or surgery have remained largely unchanged for the past 70 years and either lack efficacy for many patients, or result in lifelong thyroid hormone replacement therapy, in the case of the latter 2 options. The demand for new therapeutic options, combined with greater insight into basic immunobiology, has led to the emergence of novel approaches to treat Graves' hyperthyroidism. The current therapies under investigation include biologics, small molecules, and peptide immunomodulation. There is a growing focus on TSHR-specific treatment modalities, which carry the advantage of eliciting a specific, targeted approach, with the aim of avoiding disruption of the functioning immune system. These therapies present a new opportunity to supersede the inadequate treatments currently available for some Graves' patients, offering hope of successful restoration of euthyroidism without the need for ongoing therapy. Several of these therapeutic options have the potential to translate into clinical practice in the near future. This review provides a comprehensive summary of the recent advances and various stages of development of the novel therapeutic approaches to treat Graves' hyperthyroidism.

Efficacy of rituximab in patients with Graves' orbitopathy: a retrospective multicenter nationwide study. Graefes Arch Clin Exp Ophthalmol 2020; 258:2013-2021.

Abstract
PURPOSE The clinical utility of rituximab (RTX) in Graves' orbitopathy (GO) treatment remains controversial since the discrepant results from 2 prospective randomized studies (Stan M et al. J Clin Endocrinol Metab 2015; Salvi M et al. J Clin Endocrinol Metab 2015). The aim of this study was to assess in real life the characteristics and the clinical outcomes of patients with GO treated with RTX in cases of corticosteroid resistance or corticosteroid dependence. METHODS Multicenter French retrospective study including patients with moderate-to-severe GO requiring second-line treatment with RTX. Patients were classified according to three main baseline characteristics: clinical inflammation (CAS ≥ 3), oculomotor limitation, and visual dysfunction. Patients were considered as responders if, at 24 weeks (week 24), at least 1 of these 3 parameters improved with no worsening elsewhere. RESULTS Forty patients were included (65% smokers, 38% dysthyroidism). Thirty-two patients were treated with RTX alone (one patient excluded owing to side effects): 64.5% had favorable responses at week 24 and significant reduction in baseline CAS (3.29 ± 1.6) at 12 weeks (1.93 ± 1.1; P < 0.001) and at week 24 (1.59 ± 1.1; P < 0.001); reduction in anti-TSH receptor antibodies at week 24 (P < 0.01); and significant improvement of visual acuity (P = 0.04) and ocular hypertonia (P = 0.04) at week 12, but no improvement in oculomotor dysfunction. Eight patients needed emergency treatment with concomitant RTX and orbital decompression, with favorable outcome for 5 patients. Predictive factors for a poor response to RTX were low baseline CAS, smoker, and baseline ocular hypertonia. All patients reported good tolerance except one serious side effect (a cytokine release syndrome). CONCLUSIONS The efficiency results of RTX in reducing CAS in this cohort are just between those of Stan and Salvi. This could be explained by our delay before treatment initiation, quicker than Stan but longer than Salvi. RTX appears to be effective as a second-line treatment for the inflammatory component of GO, especially if the disease is highly active and recent.

Abstract
Graves' disease (GD) and Graves' orbitopathy are associated with stimulating thyrotropin receptor (TSHR) autoantibodies and autoreactive T cells. Recent in vitro studies suggested that sphingosine-1-phosphate (S1P) signaling is involved in the pathogenesis of orbitopathy. In this study, we explored the immune modulatory potential of S1P receptor antagonist fingolimod in a murine model for GD. Fingolimod was orally administered preventively during disease onset or therapeutically after disease onset. Administration of fingolimod during disease onset completely prevented the formation of TSHR-stimulating autoantibodies. Intervention after disease onset rarely reduced TSHR-stimulating autoantibodies and blocking autoantibodies were induced in some animals. Consequently, autoimmune hyperthyroidism characterized by elevated serum thyroxin levels, hyperplastic thyroid morphology accompanied by T cell infiltration, weight gain, enhanced body temperature, and tachycardia did not manifest preventively and showed milder manifestation in therapeutically treated animals. Importantly, examination of orbital tissue showed significant amelioration of orbitopathy manifestations through reduction of T cell infiltration, adipogenesis, and hyaluronan deposition. Autoimmune hyperthyroidism and orbitopathy were accompanied by changes in peripheral and splenic T cell proportions with high CD3+, CD4+, and CD8+ T cells. Activated T cells CD4+CD25+ were elevated whereas regulatory T cells CD4+Foxp3+ cells remained unchanged in spleens. Fingolimod decreased elevated T cell levels and increased CD4+CD25+Foxp3+ regulatory T cell populations. Analysis of total disease outcome revealed that treatment during disease onset protected animals against autoimmune hyperthyroidism and orbitopathy. Of note, therapeutic intervention after disease onset suppressed disease in half of the animals and in the other half disease remained at mild stages. The results of this study support a clinical trial to investigate the immunologic and clinical benefits of early treatment with S1P-based drugs in GD.

Abstract
Background Orbital inflammatory diseases are a heterogenic group of conditions that often entail a difficult diagnostic process and many patients are treatment resistant. Inflammatory diseases can be visualized by Zirconium-89-labelled rituximab PET-CT (89Zr-rituximab PET/CT). In this study, we describe our experience and possible potential of the 89Zr-rituximab PET/CT for diagnostic and therapeutic management of refractory orbital inflammation. Results Retrospectively, 89Zr-rituximab uptake was assessed and related to clinical data. The main outcome measures were the characteristics of the scan and the clinical relation of uptake with the diagnostic process and treatment effectivity. Twelve patients with thyroid eye disease (TED) and suspected idiopathic orbital inflammation (IOI) were scanned. Six patients had a strong 89Zr-rituximab uptake and showed a focal distribution within the lesion. Four patients (one TED, three IOI) responded well to rituximab treatment after a positive scan. 89Zr-rituximab PET/CT was essential to the diagnosis of optic nerve meningioma in one patient. Conclusion 89Zr-rituximab PET/CT has the potential to be a powerful tool for the detection of B cell-mediated disease within the orbit and ocular adnexa. This technique can be a valuable addition for diagnosing diseases around the eye and can potentially predict rituximab treatment response in patients with refractory inflammation.

Abstract
PURPOSE Management of Graves' ophthalmopathy remains challenging. Over the last decade, previous studies have shown promising results for Rituximab in the treatment of Graves' ophthalmopathy. We present the response of 14 individuals with active moderate-to-severe Graves' ophthalmopathy to Rituximab, representing one of the largest retrospective case series reported to date. METHODS Rituximab was administered intravenously, 1000 mg twice at a 2-week interval. The primary end point was a clinical activity score reduction (improvement by ⩾ 2 points or disease inactivation: clinical activity score < 3) at 24 weeks. Secondary end points included clinical activity score improved by ⩾ 2 points or inactivation of Graves' ophthalmopathy at 12 weeks, improvement in each item of the clinical activity score, in proptosis, in severity disease by the total eye score and in diplopia according to the Gorman score. RESULTS A limited improvement in clinical activity score was observed (median improvement at 24 weeks by 1 point, p = 0.002, (5/14 patients, 35.7%). Disease inactivation occurred in 50% of patients (7/14 patients). At 12 weeks, clinical activity score improved by ⩾ 2 points in 2/14 patients (14.3%) and inactivation of Graves' ophthalmopathy occurred in four patients (28.6%). Improvement in proptosis and total eye score was observed in 3/9 patients (33%) and in 4/14 patients (28.6%) at 24 weeks, respectively. Only one patient experienced moderate adverse event. CONCLUSION Rituximab is a well-tolerated treatment with a good safety profile, but offered limited and partial improvement for active moderate-to-severe Graves' ophthalmopathy with a long duration of disease.

Abstract
PURPOSE OF REVIEW The pathophysiology of thyroid eye disease (TED) is still not fully understood. However, recently described risk factors and molecular findings have brought new insights into the mechanisms of TED and could lead to the emerging use of more targeted therapies. This article aims to review the clinical findings of TED, and the most recent advances in our understanding of the risk factors and therapeutic options for TED. RECENT FINDINGS Smoking has been recently shown to have an impact on specific gene expression involved in several disease-related pathways, which seems to be reversible with smoking cessation. This finding further emphasizes the importance of smoking cessation in the prevention and treatment of TED. Selenium deficiency and high-serum cholesterol have been described to be potential independent risk factors for TED and their management could decrease the incidence and severity of TED. In terms of therapeutic options, immunomodulatory medications have shown some promising results for disease control in TED over the past years, but further randomized prospective studies with larger sample sizes are still needed to prove their efficacy. A new technique of P brachytherapy was shown to have quick therapeutic effects on TED without significant side effects and could be a promising therapy for selected cases of TED. SUMMARY TED is one of the most common autoimmune inflammatory disorders of the orbit. Although its pathophysiology remains unclear, newly described genetic findings and risk factors could help in explaining its occurrence and guide future therapies. Immunosuppressant medications are increasingly used in the management of TED, but further studies are needed to confirm their effectiveness.

Abstract
BACKGROUND The current therapies of thyroid-associated ophthalmopathy (TAO) were still a challenging matter. In this study, we aimed to contrast the impact of before- after rituximab (RTX) therapy in the patients with TAO. METHODS We searched the PubMed, EMBASE, and SCOPUS databases for articles published up to July 3, 2017. Fixed- or random-effects meta-analysis was used to provide pooled estimates of standard mean difference (SMD) both the primary outcome from clinical activity score (CAS), and secondary outcomes from thyrotropin receptor antibody (TRAb), proptosis, thyroid stimulating hormone (TSH), and interleukin-6 (IL-6) levels. In addition, the quality and each study was assessed using either the Newcastle Ottawa Scale (NOS) or the Cochrane Risk of Bias tool, and reliability of the meta-analytic result using the Grading of Recommendations Assessment, Development and Evaluation (GRADE). RESULTS Of the 839 articles initially searched, 11 studies were finally eligible for inclusion. Subgroup analysis results showed that comparing with initial value, there was a decline in CAS at 1,3,6,12 month after RTX treatment, decreased TRAbs level at 6,12 month, proptosis improvement at least 1 month, unchanged IL-6 level at 6 month, decreased TSH level at 3 month but unchanged at 12 month. All included studies were classified as good quality. CONCLUSIONS The pooled data suggested that the preliminary effects of RTX treatment on TAO might be promising. However, more large-sample and high-quality studies targeting RTX use during this disease and long-term surveillance of prognosis are urgently needed.

Abstract
INTRODUCTION Thyroid eye disease (TED) remains a notorious ailment for both patients and the treating ophthalmologists. Recent years have witnessed considerable research in the immunopathogenic mechanism of TED that has resulted in an expansion and modification of the available management options. AIM Purpose of this review is to summarise the advances in the management of thyroid ophthalmopathy. MATERIAL AND METHOD A thorough literature search and of the past 10 years web search with words Thyroid ophthalmopathy, recent, advances. RESULTS Recent VISA classification and new serum markers seem to have potential to give diagnostic as well as therapeutic guidance, gauge treatment response and even identify risk of disease progression. Majority of TED patients can be managed conservatively due to its self-limiting nature but if indicated, still steroids are the preferable medical therapy; however, there is an increasing consensus towards the use of parenteral form as compared to the oral one on account of greater efficacy with lesser side effects. Steroid sparing medications, for example, rituximab, infliximab, etanercept, adalimumab, teprotumumab, tocilizumab, tanshinone, are showing encouraging results and form an area of active research. CONCLUSION Radiation therapy remains as an adjunctive modality in active diseases as a nonmedical treatment for TED with some promising data. Surgical intervention may be required in vision threatening conditions or to counteract the sequel of inflammatory phase. Advances in surgical techniques like stereotactic image-guided balanced orbital decompression with endoscopic approach ensure meticulous dissection with minimal trauma.

Abstract
Rituximab (RTX) use in open-label series has been associated with very encouraging responses in patients with active and moderate-to-severe Graves' orbitopathy (GO). Recently, randomized controlled trials of RTX have been performed in such patients to answer the question of clinical efficacy and the safety profile of this agent. That data, reported separately, focused on Clinical Activity Score (CAS) and indicated in one trial a strong benefit of RTX in comparison with IV glucocorticoids, whereas the other trial noted the absence of a benefit by comparison with placebo. The outcome was reanalyzed post hoc here, using EUGOGO criteria, and the results were not significantly different. The authors comment further on the differences between the two trials regarding populations treated, methodology, analysis of outcomes and the adverse effect profile of RTX. The populations treated appear different with younger patients, lower TRAb and shorter duration of disease prevalent in the Italian trial, all elements favoring a better response. Smoking, usually diminishing a response, was also more prevalent in some patients. The combined outcome proposed by EUGOGO revealed similar results with CAS regarding RTX efficacy; yet, it might be a more comprehensive outcome. The adverse events of concern relate mainly to the risk of DON, which seems to be increased by the use of RTX in a certain subset of patients. Based on available data, a multicenter trial using the EUGOGO-proposed outcomes might be the next best step to define the role of RTX in GO therapy.

Abstract
Graves' orbitopathy has a deteriorating effect on patients' appearance and vision, thus significantly decreases their quality of life. A multidisciplinary team of endocrinologists, ophthalmologists, head and neck surgeons, nuclear medicine physicians, radiologists, and psychologists should constitute a standard health care team for those patients. It is vital that the therapy is based on an individual approach, with patients being well informed and involved in the decision-making process. Generally, traditional therapies include immunosuppression with steroids, orbital irradiation and surgical decompression. Novel treatment modalities include: biological agents, somatostatin analogs, antioxidants, methotrexate. Better insight into pathogenesis of Graves' orbitopathy is the only chance for targeted therapy development.

Abstract
Graves disease is an autoimmune thyroid disease classically characterised by a clinical triad consisting of hyperthyroidism, diffuse goitre, and thyroid eye disease. Thyroid eye disease is an immunologically mediated condition in which humoral immunity is thought to play a central role. Thyroid eye disease is traditionally treated with high-dose glucocorticosteroids and surgical orbital decompression. However, responses are inadequate and alternative treatment options are needed. Rituximab, an anti-CD20 monoclonal antibody, shows promise as a novel therapeutic option for thyroid eye disease. There are 43 cases of thyroid eye disease treated with rituximab in the medical literature, and larger studies are warranted to determine the long-term effectiveness of rituximab. Rituximab may represent an attractive new treatment option for thyroid eye disease, especially in the case of disease that is refractory to current treatment strategies.

Abstract
CONTEXT Graves' orbitopathy (GO) is a potentially sight-threatening disease for which available medical therapy is not uniformly successful. Multiple case series suggest that rituximab (RTX) may be effective therapy for GO patients. OBJECTIVE To determine the efficacy of RTX in GO. DESIGN It is a prospective, randomized, double-masked, placebo-controlled trial. SETTING The study was conducted at a large academic private practice. PATIENTS Twenty five patients with active moderate to severe GO were enrolled, and 21 completed the study to the primary endpoint. INTERVENTIONS Two RTX infusions (1000 mg each) or two saline infusions were given 2 weeks apart. MAIN OUTCOME MEASURES The primary endpoint was a reduction in clinical activity score (CAS) assessed as a continuum and separately as improvement by ≥ 2 points at 24 weeks. Secondary endpoints included success and failure rates, proportions showing clinically significant improvement in proptosis, lid fissure width, diplopia score, lagophthalmos and disease severity, and changes in those parameters, orbital fat/ muscle volume and quality-of-life. RESULTS The treatment groups were similar in all parameters at baseline. The last observation was carried forward if the patient discontinued prematurely. No differences were found in the proportions of patients showing CAS improvement at 24 weeks (25% placebo; 31% RTX, P = .75) or in CAS decrease from baseline to 24 or 52 weeks [mean 1.5 points (1.8 SD) placebo; 1.2 (2 SD) RTX at 24 weeks, P = .73]. Similarly, there were no differences between groups in any of the secondary endpoints at either 24 or 52 weeks. There were four adverse events (AE) in 3/12 placebo patients and 11 AE in 8/13 RTX-treated patients; 5/6 moderate or severe AE occurred in the RTX group. CONCLUSION RTX offered no additional benefit over placebo to our patients with active and moderate to severe GO and carried with it non-negligible adverse effects.

Abstract
The pathophysiology of thyroid eye disease (TED) is complex and incompletely understood. Orbital fibroblasts (OFs) seem to be the key effector cells that are responsible for the characteristic soft tissue enlargement seen in TED. They express potentially pathogenic autoantigens, such as thyrotropin receptor and insulin-like growth factor-1 receptor. An intricate interplay between these autoantigens and the autoantibodies found in Graves disease may lead to the activation of OFs, which then leads to increased hyaluronan production, proinflammatory cytokine synthesis, and enhanced differentiation into either myofibroblasts or adipocytes. Some of the OFs in TED patients seem to be derived from infiltrating fibrocytes. These cells originate from the bone marrow and exhibit both fibroblast and myeloid phenotype. In the TED orbit, they may mediate the orbital expansion and inflammatory infiltration. Last, lymphocytes and cytokines are intimately involved in the initiation, amplification, and maintenance of the autoimmune process in TED.

Abstract
Aims: The aim was to highlight recent advances in the treatment of thyroid eye disease. Settings and Design: Review article. Materials and Methods: Existing literature and the authors’ experience was reviewed. Results: Thyroid ophthalmopathy is a disfiguring and vision-threatening complication of autoimmune thyroid disease that may develop or persist even in the setting of well-controlled systemic thyroid status. Treatment response can be difficult to predict, and optimized algorithms for disease management do not exist. Thyroid ophthalmopathy should be graded for both severity and disease activity before choosing a treatment modality for each patient. The severity of the disease may not correlate directly with the activity; medical treatment is most effective in active disease, and surgery is usually reserved for quiescent disease with persistent proptosis and/or eyelid changes. Conclusions: Intravenous pulsed corticosteroids, orbital radiotherapy, and orbital surgical techniques form the mainstay of current management of thyroid ophthalmopathy. Immunosuppressive and biologic agents may have a role in treating active disease although additional safety and efficacy studies are needed.

Abstract
PURPOSE To assess the efficacy of Tocilizumab, a humanized monoclonal antibody against the interleukin-6 receptor, in thyroid eye disease patients refractory to multiple intravenous steroids. METHODS Prospective interventional nonrandomized study including active GO defined by Clinical Activity Score (CAS) ≥4 patients resistant to previous intravenous steroids treated with Tocilizumab was conducted from February 2010 to September 2012. Snellen visual acuity, Hertel exophthalmometry, CAS evaluation, TSI levels, ocular motility, and side effects were registered at a 4-week interval. RESULTS Eighteen patients were included with a mean age of 47.9 ± 8.63 years. All patients had a significant progressive CAS improvement (mean CAS score reduction 5.89 ± 1.41 points, p< 0.00027). Mean TSI levels were significantly lower at the end of the treatment (mean -76.18% ± 17.80%, p = 0.00007). Thirteen patients (72.22%) reduced proptosis a mean of -3.92 ± 1.54 mm (p = 0.002). Fifteen patients (83.33%) had an improvement in extraocular motility, and 7 patients of 13 resolved their diplopia (53.85%). No severe side effects or relapse of active GO were observed at the end of follow up. CONCLUSIONS This study suggests that intravenous Tocilizumab may be effective on reducing activity in patients with thyroid eye disease refractory to intravenous steroids.

Abstract
IMPORTANCE Orbital inflammation is a potentially blinding and disfiguring disease process that is often treated with systemic corticosteroids and immunosuppression; better treatments are needed. OBJECTIVE To determine whether rituximab, a monoclonal antibody against the B-lymphocyte antigen CD20, is effective in the treatment of refractory orbital inflammation. DESIGN, SETTING, AND PARTICIPANTS A dose-ranging, randomized, double-masked phase 1/2 clinical trial was conducted at a tertiary referral ophthalmology clinic. Ten individuals with orbital inflammation refractory to systemic corticosteroids and at least 1 other immunosuppressive agent were enrolled from January 2007 to March 2010. INTERVENTIONS Rituximab infusions were administered on study days 1 and 15 at doses of either 500 mg or 1000 mg. Initial responders with recurrent inflammation after week 24 were permitted reinfusion with an additional cycle of 2 open-label 1000-mg rituximab infusions. MAIN OUTCOMES AND MEASURES The primary outcomes were reduction of inflammation measured with a validated orbital disease grading scale and corticosteroid dose reduction by at least 50%. The secondary outcomes were visual acuity, reduction in pain, and participant- and physician-reported global health assessment. RESULTS Of 10 enrolled patients, 7 demonstrated improvement on the orbital disease grading scale at the 24-week end point with rituximab therapy. Of these 7 individuals, 4 were receiving corticosteroids at study inception and all achieved successful dose reduction. For the secondary outcome measures in the 10 participants, 7 patients and 8 patients improved in self-rated and physician global health scores, respectively, and 7 patients had reduction in pain by 25% or more at 24 weeks. Four patients who were positive responders at the week 24 end point experienced breakthrough inflammation after week 24 and received reinfusions between 24 and 48 weeks. Vision remained stable in all participants. Three of 10 patients had short-term objective or subjective worsening 2 to 8 weeks after receiving rituximab infusions, which was averted in subsequent patients with oral corticosteroids administered during the infusion and did not affect the eventual positive treatment outcome. No significant differences with regard to efficacy, toxicity, or likelihood of retreatment were noted between the dosing arms. CONCLUSIONS AND RELEVANCE Rituximab was safe and effective in 7 of 10 patients with noninfectious orbital disease, although 4 required reinfusion with rituximab to maintain control of orbital inflammation. Substantial toxicity was not noted. Rituximab should be considered in the treatment of refractory orbital inflammation. TRIAL REGISTRATION clinicaltrials.gov Identifier: NCT00415506.

Abstract
Rituximab is an emerging treatment for thyroid eye disease. Rituximab effectively depletes circulating CD20+ B-lymphocytes; however, its effect on target tissues has not been well-studied. Failures of rituximab have been infrequently reported. The authors describe a patient treated with rituximab for thyroid eye disease who failed to respond to treatment, and underwent orbital decompression. Orbital fat samples and peripheral blood samples were evaluated for the presence of CD20+ B-lymphocytes. Complete depletion of CD20+ B-lymphocytes was demonstrated in both the orbit and the blood. This case demonstrates that rituximab effectively depletes orbital CD20+ B-lymphocytes, and this depletion was maintained for 2 months despite a clinical deterioration.

Abstract
The pathophysiology underlying Graves' disease and its ocular manifestation, thyroid associated ophthalmopathy (TAO) is incompletely understood. Characterization of the mononuclear cells driving the disease and the cytokines they produce has led to significant advances in our understanding of TAO. This in turn has resulted in the identification of potentially attractive drug targets. For instance, development of inhibitors of specific cytokine pathways for use in other autoimmune diseases now presents an opportunity for their application in TAO. In this paper, we review the rationale for considering anti-cytokine therapy in TAO, evidence linking specific cytokines such as interleukin-6, tumor necrosis factor-α, and interleukin-17 pathways to TAO, and explore the potential for targeting of these pathways as therapy.

Abstract
Graves' disease (GD) is a common autoimmune condition. At its core, stimulatory autoantibodies are directed at the thyroid-stimulating hormone receptor (TSHR), resulting in dysregulated thyroid gland activity and growth. Closely associated with GD is the ocular condition known as thyroid-associated ophthalmopathy (TAO). The pathogenesis of TAO remains enigmatic as do the connections between the thyroid and orbit. This review highlights the putative molecular mechanisms involved in TAO and suggests how these insights provide future directions for identifying therapeutic targets. Genetic, epigenetic, and environmental factors have been suggested as contributory to the development of GD and TAO. Thyroid-stimulating hormone receptor and insulin-like growth factor receptor (IGF-1R) are expressed at higher levels in the orbital connective tissue from individuals with TAO than in healthy tissues. Together, they form a functional complex and appear to promote signaling relevant to GD and TAO. Orbital fibroblasts display an array of cell surface receptors and generate a host of inflammatory molecules that may participate in T and B cell infiltration. Recently, a population of orbital fibroblasts has been putatively traced to bone marrow-derived progenitor cells, known as fibrocytes, as they express CD45, CD34, CXCR4, collagen I, functional TSHR, and thyroglobulin (Tg). Fibrocytes become more numerous in GD and we believe traffic to the orbit in TAO. Numerous attempts at developing complete animal models of GD have been largely unsuccessful, because they lack fidelity with the ocular manifestations seen in TAO. Better understanding of the pathogenesis of TAO and development of improved animal models should greatly accelerate the identification of medical therapy for this vexing medical problem.

Abstract
Graves' orbitopathy (GO) is the most frequent and invalidating extrathyroidal expression of Graves' disease. Its incidence and prevalence are, however, low. About three quarters of Graves' patients have no GO at diagnosis, and moderate-to-severe and severe forms represent no more that 5-6% of cases. Progression to severe forms occurs rarely, but it may be caused by risk factors, the most important being smoking and poor control of thyroid dysfunction. Lot of progress has been recently achieved in the understanding of GO pathogenesis, while the disease remains a therapeutic challenge and dilemma. Common treatments for moderate-to-severe and active forms of GO (glucocorticoids and orbital radiotherapy) frequently provide incomplete responses and may be followed by relapse or progression of GO. After the disease has been inactivated by medical treatment, many patients need rehabilitative surgery for residual manifestations (orbital decompression for exophthalmos, squint surgery for extraocular muscle dysfunction, eyelid surgery for eyelid malposition). Novel pharmacological treatments are on the horizon and might target pathogenetic mechanisms of the disease better than glucocorticoids. Clinical evidence concerning their efficacy and safety is presently lacking.

Abstract
OBJECTIVE This case series documents the response of nine individuals with glucocorticoid-refractory Graves' orbitopathy (GO) to B cell depletion therapy with rituximab (RTX). CONTEXT Graves' disease (GD) is one of the commonest autoimmune conditions and is frequently associated with inflammatory changes around the eyes (GO). GO frequently results in significant functional visual impairment, and in the most severe cases, it can result in permanent loss of sight. RTX is a therapeutic monoclonal antibody, which targets cell-surface CD-20, resulting in depletion of circulating B lymphocytes. It has been found to be useful for the treatment of a number of autoimmune conditions including, in preliminary studies, GO. DESIGN AND PATIENTS We have treated nine individuals (1 male, 8 female, age range 37-87 years) with glucocorticoid-resistant GO with RTX since 2008. RTX was administered in divided doses at fortnightly intervals, following 500 mg IV methylprednisolone pretreatment. MEASUREMENTS Each patient underwent thorough assessment before and after RTX therapy, including thyroid function tests, B cell counts, thyroid autoantibody levels and detailed clinical assessment according to EUGOGO standard protocols. All patients have now been followed up for 16 months or more. RESULTS There was a significant reduction in thyrotropin receptor binding inhibitory immunoglobulin (TBII) levels in all patients following RTX treatment and a reduction in the clinical activity score (CAS) was seen in all cases. We also report striking improvement in pretibial thyroid dermopathy in one patient following RTX. CONCLUSIONS This case series adds to the growing literature demonstrating that RTX, administered in our patients with concomitant methylprednisolone, is safe and clinically effective in the treatment of active, moderate to severe and sight-threatening GO. Randomized controlled trials are now needed to confirm the efficacy of RTX for GO.

Abstract
BACKGROUND Thyroid associated ophthalmopathy (TAO) is the most frequent extrathyroidal manifestation of Graves' disease, affecting up to 50% of patients, and has a great impact on quality of life. Rituximab is a human/murine chimeric monoclonal antibody that targets CD20, a transmembrane protein expressed on the surface of pre-B and mature B lymphocytes, but not on stem cells, pro-B lymphocytes or plasma cells. Preliminary work has shown that blocking the CD20 receptor on B-lymphocytes with rituximab affects the clinical course of TAO, by reducing inflammation and the degree of proptosis. OBJECTIVES The aim of this review was to investigate the effectiveness and safety of rituximab for the treatment of TAO. SEARCH METHODS We searched CENTRAL (which contains the Cochrane Eyes and Vision Group Trials Register) (The Cochrane Library 2013, Issue 3), Ovid MEDLINE, Ovid MEDLINE In-Process and Other Non-Indexed Citations, Ovid MEDLINE Daily, Ovid OLDMEDLINE, (January 1950 to April 2013), EMBASE (January 1980 to April 2013), Latin American and Caribbean Literature on Health Sciences (LILACS) (January 1982 to April 2013), OpenGrey (System for Information on Grey Literature in Europe) (www.opengrey.eu/), the metaRegister of Controlled Trials (mRCT) (www.controlled-trials.com), ClinicalTrials.gov (www.clinicaltrials.gov), the WHO International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en) and the EU Clinical Trials Register (www.clinicaltrialsregister.eu). We did not use any date or language restrictions in the electronic searches for trials. We last searched the electronic databases on 15 April 2013. We manually searched references of review articles and used the Science Citation Index to identify additional studies citing trials. We contacted the lead investigators of relevant trials on ClinicalTrials.gov and the WHO ICTRP for information and data from as yet unpublished clinical trials. We contacted experts in the field for information about any ongoing trials. We contacted the manufacturers of rituximab for details of any sponsored trials. SELECTION CRITERIA We sought to include randomised controlled trials (RCTs) of rituximab treatment by intravenous infusion for the treatment of patients with TAO, compared with placebo or intravenous glucocorticoid treatment. DATA COLLECTION AND ANALYSIS Two review authors independently scanned titles and abstracts, as well as independently screened the full reports of the potentially relevant studies. At each stage, the results were compared and disagreements were solved by discussion. MAIN RESULTS No studies were identified that met the inclusion criteria. There are three ongoing studies which are likely to meet inclusion criteria once published, and thus be included in future updates of this review. AUTHORS' CONCLUSIONS There is currently insufficient evidence to support the use of rituximab in patients with TAO. There is a need for large RCTs, investigating rituximab versus placebo or corticosteroids in patients with active TAO to make adequate judgement on the efficacy and safety of this novel therapy for this condition.

Abstract
Graves' disease is an autoimmune condition commonly associated with thyroid dysfunction and with anti-thyroid antibodies, usually TSH receptor stimulating antibodies. Thyroid autoimmunity also may be associated with extra thyroidal manifestations. Most common extra thyroidal manifestation is ophthalmopathy. Less common is thyroid dermopathy, usually occurring in pretibial area. Dermopathy is almost always associated with ophthalmopathy and in severe cases with acropachy. A common antigen with thyroid in tissues of the skin and the eyes, most likely TSH receptor, is involved in pathogenesis of extra thyroidal manifestations. Presence of dermopathy and acropachy are predictors of severity of autoimmune process. Local corticosteroid application is the standard therapy for dermopathy. Response to therapy is good in mild cases and poor in severe cases. Immune modulators and biotherapies are undergoing randomized trials for ophthalmopathy component of Graves' disease. Any therapy proven to be effective for ophthalmopathy can be utilized in future for management of dermopathy.

Abstract
Thyroid eye disease (TED) is the most common extrathyroidal manifestation of Graves' disease. Incomplete understanding of its pathogenesis has hindered development of targeted therapies that might alter the natural course of disease. Smoking cessation and maintenance of euthyroidism appear to reduce the rate of onset and severity of TED. Recent evidence suggests that selenium may lessen the inflammatory symptoms in mild disease. Corticosteroids remain the primary treatment for patients with moderate to severe active TED. Surgical decompression is commonly undertaken in the chronic stable phase, and only rarely in the active phase when vision is threatened by compressive optic neuropathy. Orbital radiotherapy remains an adjunctive strategy during active disease. Targeted immunotherapies have the potential to alter disease progression, but further evidence is needed to establish safety and efficacy. In this article, we review evidence from prospective therapeutic trials of several treatment modalities. We focus on moderate to severe active TED.

Abstract
The etiology of Graves' orbitopathy (GO) remains enigmatic. Optimal therapeutic choices for the hyperthyroidism associated with Graves' disease (GD) in the presence of GO remain controversial. Whether antithyroid drugs (ATDs), radioiodine (RAI), or thyroidectomy should be favored in such patients remains debated. Pre-therapy variables such as ethnicity, sex, age, thyroid function, level of TSH-receptor antibodies and smoking behavior influence response to therapy. Among the most important management goals are restoring euthyroidism and abstaining from smoking. On average, ATDs and thyroidectomy - independent of extent - do not influence the natural course of GO. RAI can cause de novo development or progression of GO, which is largely preventable with oral steroid prophylaxis. In patients with mild GO, the thyroid treatment is largely independent of GO. Moderate to severe GO should be treated promptly. Deciding whether, in the latter, GD is better treated with ATDs, RAI, or surgery, is based more on expert opinion than on evidence. It is clear that in the individual patient a number of factors, not addressed in any trial, influence the final choice of therapy for GD, including concern of developing or negatively affecting pre-existing GO. Evidently, there is room for improving therapy of GO. Progress using novel drugs such as rituximab, which might potentially influence positively both GD and GO, are impatiently awaited.

Abstract
In Graves ophthalmopathy, immunotherapy is offering an opportunity of reducing bad outcomes that lead to disfigurement and impairment of vision. These therapies are not perfect; however, we now have a chance to achieve better outcomes. In asthma, immune therapy using passive immunity targeting key proinflammatory cytokine/chemokines and medications of their effects has opened an avenue of research into a safe and durable therapy. Omalizumab appears to be safe and effective in clinical use. In regional pain syndrome, immune mechanisms may be involved in sustaining long-standing pain, and IVIG may moderate pain sensitivity by reducing immune activation.

Abstract
PURPOSE OF REVIEW Thyroid eye disease (TED) is a poorly understood autoimmune manifestation most commonly associated with Graves' disease. Current nonspecific treatment paradigms offer symptomatic improvement but fail to target the underlying pathogenic mechanisms, and thus do not significantly alter the long-term disease outcome. The purpose of this review is to provide an update of the current understanding of the immunopathogenesis of TED and explore these mechanisms for targeted immunotherapy. RECENT FINDINGS Orbital fibroblasts are integral to the pathogenesis of TED and may modulate immune responses by production of cytokines and hyaluronan in response to activation of shared autoantigens including thyrotropin receptor and insulin-like growth factor-1 receptor. Bone marrow-derived fibrocytes share many of these phenotypic and functional features, suggesting a link between systemic and site-specific disease. Use of targeted immunotherapies in TED is limited, though data from the use Rituximab (RTX), a B-cell depleting agent, are encouraging. Sustained clinical response has been seen with RTX in several reports, despite return of peripheral B-cell levels to pretreatment levels. Additionally, this response appears to be independent of cytokine and antibody production, suggesting modulation of antigen presentation as a mechanism of its effect. SUMMARY Progressive advances in the understanding of the immunopathogenesis of TED continue to spur clinical trials utilizing targeted immune therapies. Continued understanding of the molecular mechanisms of disease will expand potential treatments for TED patients and obviate the need for reconstructive surgical therapies.
