Abstract
PURPOSE Thyroid eye disease (TED) is the most common extrathyroidal manifestation of Graves disease. Patients may be severely affected with eyelid retraction, exophthalmos, diplopia, pain, and threatened vision. Autoantibodies against thyroid-stimulating hormone receptor and insulin-like growth factor 1 receptor have shown associations with pathophysiological and clinical traits. Autoantibodies against thyroid-stimulating hormone receptor is in current clinical use as biomarker, but not with unambiguous diagnostic performance. A biomarker with high diagnostic accuracy and/or prognostic capability would be of immense value in diagnosing TED, especially in subclinical cases or when TED precedes the thyroid dysfunction. This article is a literature review on molecular biomarkers of TED. METHODS A literature search was performed using PubMed and Embase. Studies on molecular biomarkers in blood, tear fluid, and urine were included in the review. RESULTS Forty-six papers were included, of which 30, 14, and 2 studies on biomarkers in blood, tears, and urine, respectively. Fourteen of the papers evaluated the diagnostic performance of various biomarkers, 12 in blood and 2 in tears. Most studies evaluated single biomarkers, but 3 tested a panel of several markers. Except for autoantibodies against thyroid-stimulating hormone receptor, the reported diagnostic performances for the biomarkers were not confirmed in independent cohorts. In 32 studies, no or insufficient performance data were given, but the findings indicated involvement of various biologic mechanisms in TED including inflammation, oxidative stress, fibrosis, lipid metabolism, and ocular surface microflora. CONCLUSIONS Currently, serum autoantibodies against thyroid-stimulating hormone receptor is the only molecular biomarker with clinical utility in patients with TED. Several potential biomarkers have been investigated, and particularly panels of multiple biomarkers in tears are promising. To improve patient care, biomarkers in TED should be studied further.

Abstract
PURPOSE Dysthyroid optic neuropathy (DON) is a rare sight-threatening complication of Graves' disease. First-line treatment for DON consists of high-dose intravenous methylprednisolone (ivMP), followed by immediate orbital decompression (OD) if the response is poor or absent as recommended by the 2021 European Group on Graves' orbitopathy guidelines. The safety and efficacy of the proposed therapy have been proven. However, consensus regarding possible therapeutic options for patients with contraindications to ivMP/OD or resistant form of disease is missing. This paper aims to provide and summarize all available data regarding possible alternative treatment strategies for DON. METHODS A comprehensive literature search within an electronic database was performed including data published until December 2022. RESULTS Overall, 52 articles describing use of emerging therapeutic strategies for DON were identified. Collected evidence indicates that biologics, including teprotumumab and tocilizumab, may be considered as an important possible treatment option for DON patients. Rituximab should be avoided in DON due to conflicting data and risk of adverse events. Orbital radiotherapy could be beneficial for patients with restricted ocular motility classified as poor surgical candidates. CONCLUSION Only a limited number of studies have been dedicated to the therapy of DON, mostly retrospective with a small sample size. Clear criteria regarding diagnosis and resolution of DON do not exist, which restricts comparison of therapeutic outcomes. Randomized clinical trials and comparison studies with long-term follow-ups are necessary to verify the safety and efficacy of each therapeutic option for DON.

Abstract
Thyroid-associated ophthalmopathy (TAO), also known as thyroid eye disease (TED) or Graves' orbitopathy (GO), is a complex autoimmune condition causing visual impairment, disfigurement, and harm to patients' physical and mental health. The pathogenesis of TAO has not been fully elucidated, and the mainstream view is that coantigens shared by the thyroid and orbit trigger remodeling of extraocular muscles and orbital connective tissues through an inflammatory response. In recent years, cytokines and the immune responses they mediate have been crucial in disease progression, and currently, common evidence has shown that drugs targeting cytokines, such as tocilizumab, infliximab, and adalimumab, may be novel targets for therapy. In this review, we summarize the research development of different cytokines in TAO pathogenesis in the hope of discovering new therapeutic targets.

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
One of the most important pathogenetic mechanisms of autoimmune thyroiditis (AIT) is the violation of immunological tolerance and the development of the autoimmune process, the markers of which are various biologically active substances, in particular, matrix metalloproteinases (MMP) of the extracellular matrix (ECM). MMPs play a crucial role in the development of pathological processes in these diseases, contributing to matrix degradation due to imbalance between the activity of enzymes and their inhibitors. The aim of the work was to study the activity of key metalloproteinases and the level of α2-macroglobulin in patients with autoimmune thyroiditis. The diagnosis of AIT was established based on the study of data on anamnesis, thyroid status, the results of ultrasound of TG, and the presence of antibodies to the thyroid-stimulating hormone receptor (TSH) in blood plasma. Patients were enrolled in 2 groups: group 1 – 74 patients with a manifest form of the disease; group 2 – 96 patients with a subclinical form of the disease. The study of matrix metalloprotein activity in the examined patients showed a statistically significant (P = 0.015) increase in MMP-3 and MMP-7 activity in patients with AIT compared to the corresponding parameters in persons of the control group. Thus, levels of MMP-3 and 7 were in the group of patients, respectively 56 (51.0; 59.0) and 4.6 (4.3; 5.2) ng/ml, in control 23.0 (16.0; 26.0) and 3.6 (3.4; 4.1) ng/ml, respectively.

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
Background: Graves' orbitopathy (GO) is an autoimmune-driven manifestation of Graves' disease (GD) where pathogenic autoantibodies to the thyrotropin receptor (TSHR) activate orbital fibroblasts/preadipocytes in the orbital tissue to induce inflammation and extracellular matrix deposition. Since there are significant limitations to study immunological and proinflammatory mediator expression in early and during disease progression in GO patients, we used our experimental mouse model to elucidate early pathogenic processes. Methods: We have developed a robust mouse model of GD/GO induced by electroporation immunization of plasmid encoding human TSHR A-subunit, comprising multiple injections over a course of 15 weeks to fully recapitulate the orbital pathology. In this study, we investigated kinetics of GO development in the model by serial analyses of immunological and cellular parameters during course of orbital inflammation. Results: Pathogenic anti-TSHR antibodies with thyroid-stimulating properties developed early after the second immunization step with concomitant induction of hyperthyroidism. Examination of orbital tissue showed an early wave of macrophage infiltration followed subsequently by CD3+ T cells into the orbital tissue. Examination of antigen-specific T cell activity using recombinant human A-subunit protein showed high CD8+ T cell proliferation during this early phase of disease onset, whereas effector CD4+ T cells and CD25+FOXP3+ regulatory T cells (Tregs) were downregulated. The early phase of disease was also characterized by abundant presence of proinflammatory cytokines interferon-γ (IFN-γ) and tumor necrosis factor-α (TNF-α). Moreover, as the disease progressed, there was significant increase in browning of orbital fat tissue, which may be dependent on the proinflammatory milieu and/or the increased thyroid hormone levels during the established hyperthyroid status. Conclusions: This work revealed early infiltration of macrophages in the orbital region and induction of pathogenic anti-TSHR antibodies during disease onset in the model. This was followed subsequently by influx of CD8+ T cells specific for TSHR coupled with reduction in Tregs and substantial increase in brown adipose tissue. These new insights into the development of orbital inflammation in the model have implications for testing new therapeutic regimens by targeting macrophage function during early phases of orbital inflammation in the model.

Abstract
Purpose: To demonstrate the efficacy of subcutaneous tocilizumab (TCZ-SC) treatment for recalcitrant thyroid eye disease (TED) refractory to intravenous methylprednisolone (MP) and oral methotrexate (MTX).Case summary: (Case 1) A 52-year-old man, smoker, with hyperthyroidism presented with a 3-months history of TED. The initial clinical activity score (CAS) was 5 (total score of 7). High-dose intravenous MP and oral MTX failed to improve the symptoms. He was treated with four doses of 162 mg TCZ-SC at an interval of 2 weeks. Pre-treatment laboratory test results were within normal limits. CAS was reduced to 2 weeks after the final injection, and there were no recurrences during the 6-month follow-up. (Case 2) A 37-year-old woman, non-smoker, with a 3-months history of hyperthyroidism presented with conjunctival injection and upper eyelid erythema. The initial CAS was 4, and thyroid-stimulating immunoglobulin level was raised (475% of normal). The symptoms did not improve with 7.5 g intravenous MP and oral MTX. The patient was treated with 162 mg TCZ-SC. Pre-treatment laboratory test results were within normal limits. CAS was reduced to 1 after the final injection, and there were no recurrences during the 6-months follow-up.Conclusions: TCZ-SC improves symptoms of corticosteroid-resistant TED, and may be a reasonable option in recalcitrant TED cases. However, further studies are required to justify the use of TCZ-SC for TED.

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
Thyroid eye disease (TED) is a complex disease associated with myriad clinical presentations, including facial disfigurement, vision loss, and decreased quality of life. Traditionally, steroid therapy and/or radiation therapy were commonly used in the treatment of active TED. While these therapies can help reduce inflammation, they often do not have a sustainable, significant long-term effect on disease outcomes, including proptosis and diplopia. Recent advances in our understanding of the pathophysiology of TED have shifted the focus of treatment toward targeted biologic therapies. Biologics have the advantage of precise immune modulation, which can have better safety profiles and greater efficacy compared to traditional approaches. For instance, the insulin-like growth factor-1 receptor (IGF-1R) has been found to be upregulated in TED patients and to colocalize with the thyroid-stimulating hormone receptor (TSHR), forming a signaling complex. Teprotumumab is an antibody targeted against IGF-1R. By inhibiting the IGF-1R/TSHR signaling pathway, teprotumumab may reduce the production of proinflammatory cytokines, hyaluronan secretion, and orbital fibroblast activation in patients with TED. Due to promising phase II and III clinical trial results, teprotumumab has become the first biologic US Food and Drug Administration (FDA)-approved for the treatment of TED. In addition, there are currently ongoing studies looking at the use of antibodies targeting the neonatal Fc receptor (FcRn) in various autoimmune diseases, including TED. FcRn functions to transport immunoglobulin G (IgG) and prevent their lysosomal degradation. By blocking the recycling of IgG, this approach may dampen the body's immune response, in particular the pathogenic IgG implicated in some autoimmune diseases. Advances in our understanding of the pathophysiology of TED, therefore, are leading to more targeted therapeutic options, and we are entering an exciting new phase in the management of TED. This review will cover recent insights into the understanding of TED pathophysiology and novel treatment options as well as ongoing studies of new potential treatment options for TED.

Abstract
BACKGROUND Graves' Orbitopathy (GO) - also known as Thyroid Eye Disease (TED) - is an autoimmune condition in the modern sense. It is closely associated with autoimmune thyroid diseases. Cytokine-mediated mechanisms play a critical part in immunopathogenesis of autoimmune thyroid diseases including GO. Investigating cytokine profiles as well as antibodies to tissue-specific antigens is essential for explaining GO pathogenesis and developing future therapeutic strategies. AIMS The study examines serum levels of cytokines, autoantibodies and immunoglobulins IgG and IgG4 as mediators of autoimmune inflammation in patients with GO and Graves' Disease (GD). MATERIALS AND METHODS The study included 52 patients (104 orbits) aged 25-70 years (mean age 48,8±12,3) in the active phase of GO and GD verified with the international diagnostic standards. These patients did not get any treatment for GO before. The control group consisted of 14 individuals (28 orbits) aged 30-68 years without known autoimmune disease.Serum levels of IgG, IgG4,TNFα, IL-1α, IL-1β, IL-2, IL-4, IL-6, IL-8, IL-10, IL-17A, IL-13, sIL-6R, sTNFα- RI и TNFα- R2 IL-2R, TGFβ1, TGF β3, antibodies to TSH-receptor, free T4, free T3 and TSH were measured. A diagnostic ultrasound exam of thyroid gland, multislice computed tomography (MSCT) / magnetic resonance imaging (MRI) of orbits were performed. RESULTS Mean duration of GO prior to being admitted to the centre was 8,8±1,5 months (range: 1 - 48 months). According to the degree of thyrotoxicosis compensation: 24 patients were clinically euthyroid, TSH 3,3±0,7 mU/L, free T4 11,9±0,59 pmol/L, free T3 3,97±0,1 pmol/L; 28 patients were considered to have subclinical thyrotoxicosis: TSH 0,03±0,01 mU/L, free T4 14,2±1,0 pmol/L, free T3 5,77±0,49 pmol/L. Serum levels of sTNFα-R2 (p=0,041, p≤0,05), sIL-2R (p=0,020, p≤0,05), TGFβ1 (p=0,000, p≤0,001) were significantly higher in patients with GO compared to the control group. Serum levels of sTNFRα2 (p=0,038, p<0,05) and TGFβ1 (P=0,011, p≤0,05) were positively correlated with the duration of GO. The positive correlations between the serum level of sIL-6R (p=0,034, p≤0,05) and the severity of GO as well as between the serum level of sTNFα- R 1 (P=0,012, p≤0,05) and activity of GO were observed. 54% of patients had elevated concentration level of IgG4 in IgG ( >5%). CONCLUSION High levels of soluble cytokine receptors sTNFα-R2 and sIL-2R and cytokine TGFβ1 in patients with long-standing untreated GO and GD being euthyroid or having subclinical thyrotoxicosis indicate activation of regulatory T cells aimed at suppressing autoimmune processes. High concentration level of IgG4 in IgG and cytokine TGFβ1 can determine the development of fibrotic changes in the orbital tissues. A decrease in the concentration of cytokine TGFβ1 can indicate an unfavorable course of the disease GO.

[PMID: 32878150 PMCID: PMC7563792 DOI: 10.3390/jcm9092816] [Citation(s) in RCA: 38] [Impact Index Per Article: 9.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2020] [Revised: 08/18/2020] [Accepted: 08/29/2020] [Indexed: 12/14/2022] Open
Abstract
Graves' orbitopathy (GO) is the most common extrathyroidal manifestation of Graves' disease (GD). Our aim was to assess the efficacy and safety of Tocilizumab (TCZ) in GO refractory to conventional therapy. This was an open-label multicenter study of glucocorticoid-resistant GO treated with TCZ. The main outcomes were the best-corrected visual acuity (BVCA), Clinical Activity Score (CAS) and intraocular pressure (IOP). These outcome variables were assessed at baseline, 1st, 3rd, 6th and 12th month after TCZ therapy onset. The severity of GO was assessed according to the European Group on Graves' Orbitopathy (EUGOGO). We studied 48 (38 women and 10 men) patients (95 eyes); mean age ± standard deviation 51 ± 11.8 years. Before TCZ and besides oral glucocorticoids, they had received IV methylprednisolone (n = 43), or selenium (n = 11). GO disease was moderate (n =29) or severe (n = 19) and dysthyroid optic neuropathy (DON) (n = 7). TCZ was used in monotherapy (n = 45) or combined (n = 3) at a dose of 8 mg/kg IV every four weeks (n = 43) or 162 mg/s.c. every week (n = 5). TCZ yielded a significant improvement in all of the main outcomes at the 1st month that was maintained at one year. Comparing the baseline with data at 1 year all of the variables improved; BCVA (0.78 ± 0.25 vs. 0.9 ± 0.16; p = 0.0001), CAS (4.64 ± 1.5 vs. 1.05 ± 1.27; p = 0.0001) and intraocular pressure (IOP) (19.05 ± 4.1 vs. 16.73 ± 3.4 mmHg; p = 0.007). After a mean follow-up of 16.1 ± 2.1 months, low disease activity (CAS ≤ 3), was achieved in 88 eyes (92.6%) and TCZ was withdrawn in 29 cases due to low disease activity (n = 25) or inefficacy (n = 4). No serious adverse events were observed. In conclusion, TCZ is a useful and safe therapeutic option in refractory GO treatment.

Abstract
PURPOSE Immunohistochemistry of orbital tissues offers a correlation between the microscopic changes and macroscopic clinical manifestation of Graves' orbitopathy (GO). Summarizing the participation of different molecules will help us to understand the pathogenesis of GO. METHODS The pertinent and current literature on immunohistochemistry of human orbital tissue in GO was reviewed using the NCBI PubMed database. RESULTS 33 articles comprising over 700 orbital tissue samples were included in this review. The earliest findings included the demonstration of HLA-DR and T cell (to a lesser extent B cell) markers in GO orbital tissues. Subsequent investigators further contributed by characterizing cellular infiltration, confirming the presence of HLA-DR and TSHR, as well as revealing the participation of cytokines, growth factors, adhesion molecules and miscellaneous substances. HLA-DR and TSHR are over-expressed in orbital tissues of GO patients. The inflammatory infiltration mainly comprises CD4 + T cells and macrophages. Cytokine profile suggests the importance of Th1 (especially in early active phase) and Th17 immunity in the pathogenesis of GO. Upregulation of proinflammatory/profibrotic cytokines, adhesion molecules and growth factors finally culminate in activation of orbital fibroblasts and perpetuation of orbital inflammation. The molecular status of selected parameters correlates with the clinical presentation of GO. CONCLUSION Further investigation is warranted to define precisely the role of different molecules and ongoing search for new players yet to be discovered is also important. Unfolding the molecular mechanisms behind GO will hopefully provide insights into the development of novel therapeutic strategies and optimize our clinical management of the disease.

Abstract
The body's autoimmune process is involved in the development of Graves' disease (GD), which is manifested by an overactive thyroid gland. In some patients, autoreactive inflammatory reactions contribute to the development of symptoms such as thyroid ophthalmopathy, and the subsequent signs and symptoms are derived from the expansion of orbital adipose tissue and edema of extraocular muscles within the orbit. The autoimmune process, production of antibodies against self-antigens such as TSH receptor (TSHR) and IGF-1 receptor (IGF-1R), inflammatory infiltration, and accumulation of glycosaminoglycans (GAG) lead to edematous-infiltrative changes in periocular tissues. As a consequence, edema exophthalmos develops. Orbital fibroblasts seem to play a crucial role in orbital inflammation, tissue expansion, remodeling, and fibrosis because of their proliferative activity as well as their capacity to differentiate into adipocytes and myofibroblasts and production of GAG. In this paper, based on the available medical literature, the immunological mechanism of GO pathogenesis has been summarized. Particular attention was paid to the role of orbital fibroblasts and putative autoantigens. A deeper understanding of the pathomechanism of the disease and the involvement of immunological processes may give rise to the introduction of new, effective, and safe methods of treatment or monitoring of the disease activity.

Abstract
Thyroid eye disease (TED) is a complex, debilitating autoimmune disease that causes orbital inflammation and tissue remodeling, resulting in proptosis, diplopia, and in severe cases, loss of vision. TED can lead to facial disfigurement and severely impact patients’ quality of life. Although the course of TED was identified over 60 years ago, effective treatment options have proved to be challenging. Current treatments such as glucocorticoid therapy and orbital radiation focus on reducing orbital inflammation. However, these therapies fail to modify the disease outcomes, including proptosis and diplopia. Recent advances in the understanding of the molecular basis of TED have facilitated the development of targeted molecular therapies such as teprotumumab, an insulin-like growth factor-1 receptor inhibiting monoclonal antibody. In recent phase 2 and phase 3 randomized placebo-controlled trials, teprotumumab rapidly achieved improvement in clinical endpoints defining TED, including improved proptosis and diplopia. Dramatic improvement in clinical outcomes achieved after teprotumumab therapy during active TED are heretofore singular and comparable only to surgical therapies achieved during the inactive phase of TED. The advent of effective medical therapy can lead to a paradigm shift in the clinical management of TED. This review will provide an overview of TED, its epidemiology, insight into the molecular biology of the disease, clinical characteristics and diagnosis, and current and emerging treatment modalities.

Abstract
BACKGROUND Thyroid eye disease (TED) is an autoimmune disorder that constitutes a major clinical and therapeutic challenge. Current treatment options for moderate-to-severe TED include immunotherapy, orbital radiotherapy and decompression surgery. Limited drugs of proven efficacy are available for the treatment of people with TED. Given the role in the pathogenesis of TED of interleukin (IL)-6 expression in adipocytes, fibroblasts and macrophages, the proposed theory is that inhibition of IL-6 by tocilizumab may be an effective treatment in TED by directly reducing the inflammatory response. In addition, there is an unmet need for a new treatment that can modify the natural course of the disease and reduce the incidence of late complications that can occur as a result of fibrosis following inflammation. OBJECTIVES To investigate the efficacy and harms of tocilizumab for the treatment of people with TED. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (which contains the Cochrane Eyes and Vision Trials Register) (2018, Issue 6); MEDLINE Ovid; Embase Ovid; LILACS BIREME; OpenGrey; the ISRCTN registry; ClinicalTrials.gov; the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) and the EU Clinical Trials Register. The date of the search was 31 July 2018. SELECTION CRITERIA We searched for trials of tocilizumab administered by intravenous infusion using any dosage regimen, compared with placebo or intravenous glucocorticoid therapy for people with TED. DATA COLLECTION AND ANALYSIS We planned to use standard methods recommended by Cochrane. The primary outcome was change in TED score (as defined by investigators). Secondary outcomes included measurement of the following parameters: change in proptosis, change in extraocular motility, change in palpebral aperture measurements, number of relapses, development of optic neuropathy and change in quality of life score. We planned to measure these outcomes at three months (range two to six months) and 12 months (range six to 18 months) post-treatment. Adverse outcomes included any adverse effects identified in the trials at any time point. MAIN RESULTS No studies met the inclusion criteria of this review. We found one randomised, placebo-controlled, double masked study (NCT01297699). This study plans to evaluate the efficacy and harms of tocilizumab administration in people with moderate-to-severe or sight-threatening graves' ophthalmopathy (GO), that had not responded adequately to treatment with intravenous corticosteroid pulses. It was completed in December 2015 and will be assessed for inclusion in the review when data become available. AUTHORS' CONCLUSIONS There is currently no evidence from randomised controlled trials evaluating the efficacy and harms of tocilizumab for the treatment of people with TED.

Abstract
Tocilizumab, in a preliminary study, was reported to be an effective therapy for moderate to severe thyroid eye disease. The authors describe the clinical response of 2 severe thyroid eye disease cases refractory to intravenous steroids and orbital decompression. Both patients demonstrated improved clinical activity scores with minimal side effects after tocilizumab therapy. In addition, post tocilizumab orbital fat biopsies demonstrated benign adipose tissue without evidence of inflammatory cells.

Abstract
PURPOSE OF REVIEW Significant advances have been made in oncology and rheumatology with the introduction of molecularly targeted agents (MTAs). MTAs consist of monoclonal antibodies and small molecule inhibitors. The purpose of this manuscript is to review the recent applications of MTAs to orbital, lacrimal, and eyelid disease. RECENT FINDINGS The use of monoclonal antibodies has been described in the treatment of orbital vascular lesions, lymphoma, and squamous cell carcinoma. Inflammatory conditions treated with monoclonal antibodies include thyroid eye disease, IgG4 disease, and granulomatosis with polyangiitis. Immunotherapy with checkpoint inhibitors has also found applications to orbital disease. Use of small molecule inhibitors has been described in the treatment of basal cell carcinoma, squamous cell carcinoma, and Erdheim-Chester disease. There are many orbital, lacrimal, and eyelid side effects of MTAs with which the oculoplastic surgeon should be familiar, including hypertrichosis, edema, and orbital and eyelid inflammation. SUMMARY MTAs represent the future of treatment of oncologic and inflammatory conditions. Application of these agents to orbital, lacrimal, and eyelid disease will continue to expand. Elucidating the molecular mechanisms of oculoplastic disorders will facilitate additional potential pathways that could be targeted for 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
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
Interleukin-6 (IL-6) is a key cytokine featuring redundancy and pleiotropic activity. It plays a central role in host defence against environmental stress such as infection and injury. Dysregulated, persistent interleukin (IL)-6 production has been implicated in the development of various autoimmune, chronic inflammatory diseases and even cancers. Significant elevation of IL-6 has been found in ocular fluids derived from refractory/chronic uveitis patients. In experimental autoimmune uveitis models with IL-6 knock-out mice, IL-6 has shown to be essential for inducing inflammation. IL-6 blockade can suppress acute T helper type 17 (Th17) responses via its differentiation and, importantly, can ameliorate chronic inflammation. Tocilizumab, a recombinant humanized anti-IL-6 receptor antibody, has been shown to be effective in several autoimmune diseases, including uveitis. Herein, we discuss the basic biology of IL-6 and its role in development of autoimmune conditions, focusing particularly on non-infectious uveitis. It also provides an overview of efficacy and safety of tocilizumab therapy for ocular inflammatory diseases.

Abstract
PURPOSE OF REVIEW Basic science studies directed at understanding the inflammatory mechanisms in chronic rhinosinusitis (CRS) are increasing, yet their relevance to the underlying disease process is often conflicting and confounded by the enrollment of a heterogeneous CRS population. This review is aimed at exploring the issues affecting the basic science mucosal studies of CRS patients, with special attention to the inclusion criteria for CRS and the control group, and the site from which the mucosal tissue sample is obtained. RECENT FINDINGS A common confounding factor is an inadequate documentation of selection criteria for patients, controls, and tissue sites examined. Inconsistent definitions for CRS and for maximum medical therapy, and a lack of histopathology confirmation of mucosal inflammation (eosinophilic or neutrophilic) can bias the disease population entering a given study. Further confounding factors include the influence of coexisting diseases, pollution and cigarette smoke, and a need for same-site tissue comparisons, meticulous selection of relevant controls, and consensus on 'nondiseased' mucosal inflammatory cell populations and microbiology. SUMMARY Documentation of well defined patient and control groups, standardized specimen collection methods, and detection assays are critical in minimizing the bias and conflicting findings among investigators. With standardized sampling of tissue sites and tight controls on subcategories of CRS patients enrolled, studies will more likely identify the findings that can increase our understanding of the disparate group of CRS patients and identify new therapeutic targets in the CRS subcategories.
