Project description: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.

Project description:Background:On 21st January 2020, the FDA approved Tepezza (teprotumumab-trbw) for the treatment of active Graves' orbitopathy (GO) in adults. This approval was based on positive results from two multinational randomised double-blind placebo-controlled clinical trials. Discussion:This article discusses the outcomes of those trials and the potential role of teprotumumab in altering current treatment paradigms in Graves' orbitopathy. Future challenges are explored, including the need to confirm its disease-modifying effect, to establish its optimal position in the treatment pathway, and to define the appropriate subset of patients who would benefit from its use. Conclusions:The results from these two large clinical trials have shown teprotumumab to have remarkable effects on multiple clinical outcomes in GO, particularly in its ability to reverse proptosis. It may herald a new era in the treatment of thyroid eye disease and could offer an alternative to surgery and its associated complications. Additional studies will continue to shape the treatment of GO and define the role of teprotumumab within the treatment paradigm.

Project description:BACKGROUND: Preliminary studies have shown that rituximab (RTX) is effective in the treatment of active Graves' orbitopathy (GO). METHODS: We conducted a double-blind, randomized trial (European Clinical Trials Database [EudraCT] 2007-003910-33) to compare RTX with iv methylprednisolone (ivMP) in patients with active moderate to severe GO. Thirty-two patients were randomized to receive either ivMP (7.5 g) or RTX (2000 or 500 mg). The primary end point was the decrease of the clinical activity score of 2 points or to less than 3 at week 24. Changes of proptosis, lid fissure, diplopia and eye muscle motility, and quality of life score were secondary end points. The number of therapeutic responses, disease reactivation, and surgical procedures required during follow-up and the patients' quality of life were also assessed. RESULTS: The clinical activity score decreased with both treatments but more after RTX at 16, 20, and 24 weeks (P < .04, P < .02, P < .006, respectively), whether 1000 mg RTX twice or 500 mg RTX once was used (P = NS). At 24 weeks 100% of RTX patients improved compared with 69% after ivMP (P < .001). Disease reactivation was never observed in RTX patients but was observed in five after ivMP. Patients treated with RTX scored better motility at 52 weeks in both the right (P = .014) and the left eye (P = .026). Overall rehabilitative surgical procedures carried out during follow-up (at 76 wk) were 12 in 16 ivMP patients and 5 in 15 RTX patients (P = .049). CONCLUSIONS: The results of this trial confirm preliminary reports on a better therapeutic outcome of RTX in active moderate to severe GO, when compared with ivMP, even after a lower RTX dose. The better eye motility outcome, visual functioning of the quality of life assessment, and the reduced number of surgical procedures in patients after RTX seem to suggest a disease-modifying effect of the drug.

Project description:Aim. To study the efficacy and safety of subantimicrobial dose (SD) doxycycline(50 mg/d) in patients with active and moderate-to-severe Graves' orbitopathy (GO). Methods. Thirteen patients with active and moderate-to-severe GO received once daily oral doxycycline (50 mg/d) for 12 wk. Treatment response at 24 wk was used as the primary outcome, measured by a composite of improvement in Clinical Activity Score (CAS), diplopia, motility, soft tissue swelling, proptosis, and eyelid aperture. Secondary outcome was the change of quality of life score (QoL, including visual functioning subscale and appearance subscale). Adverse events were also recorded. Results. Overall improvement was noted in eight out of 13 patients (61.5%, 95% CI 31.6%-86.1%). Both CAS and soft tissue swelling significantly ameliorated in eight patients at 24 wk. Five patients (38.5%) had improvement in ocular motility of ≥8 degrees. Eyelid aperture (46.2%) also decreased remarkably. For QoL, a significant improvement in appearance subscale (P = 0.008) was noted during the study, whereas no difference was observed in visual functioning subscale (P = 0.21). Two patients reported mild stomachache at 12 wk. Conclusions. SD doxycycline appears to be effective and safe for the treatment of active and moderate-to-severe GO. It might serve as a new promising therapeutic strategy for GO. This trial is registered with NCT01727973.

Project description:The most important of the extra-thyroidal manifestations of Graves' disease, Graves' orbitopathy (GO), remains a vexing clinical problem. Treatment of severe active disease has been limited to steroids or radiotherapy. In the relatively rare case where vision is threatened, emergent decompression surgery can be performed. The proptosis, motility, or cosmetic concerns associated with stable GO are commonly remedied with surgical intervention. Substantial obstacles have prevented the development of specific medical therapies for GO, in large part resulting from poor understanding of disease pathogenesis and the absence of preclinical animal models. Fundamental aspects of GO's etiology have been uncovered from studies based in cell culture, extensive analysis of blood constituents, and detailed examination of orbital contents collected at the time of surgical intervention. Many of the published reports resulting from these studies are descriptive and all have failed to yield unifying concepts that integrate the anatomically divergent manifestations of Graves' disease. This brief review covers recent findings of several research groups. While major breakthroughs continue to occur in closely related autoimmune diseases, progress in identifying the pathogenic mechanisms relevant to GO has been limited. As emerging insights into human autoimmunity becomes applied to the study of Graves' disease, we anticipate that improved therapeutic strategies will find their way to our patients with GO.

Project description:ObjectivesTo investigate the predictive factors for changes in the quality of life (GO-QoL) of patients with Graves' orbitopathy (GO) prior to and after specific treatment.MethodsA prospective follow-up study was conducted at an academic tertiary referral orbital center with a joint thyroid-eye clinic on 100 consecutive patients with GO. Before and after the standard 12-week course of weekly intravenous methylprednisolone (cumulative dose 4.5 g), the GO-QoL questionnaire provided by the European Group on Graves' Orbitopathy (EUGOGO) was completed. Endocrine and ophthalmic assessments were performed at each visit.ResultsAll patients were biochemically euthyroid and untreated for GO at baseline and presented with active and moderate-to-severe disease. Both GO-QoL subscales (visual functioning [VF] and appearance [AP]) significantly increased after immunosuppressive therapy and showed a sustained improvement for 6 months. At baseline, demographic variables (sex, age, and smoking) influenced QoL in the stepwise linear regression (p < 0.01, adjusted R 2 = 0.24 for VF and p < 0.01, adjusted R 2 = 0.21 for AP). In contrast, 6 months after treatment, the improved QoL was now exclusively associated with ophthalmic parameters (p < 0.01, adjusted R 2 = 0.47 for VF; p < 0.01, adjusted R 2 = 0.23 for AP).ConclusionsPredictive factors for GO-QoL differed not only between the 2 subscales but also before and after the first treatment of GO.

Project description:Graves' orbitopathy (GO), also known as thyroid-associated ophthalmopathy, is the most common ocular abnormality of Graves' disease. It is a disfiguring, invalidating, and potentially blinding orbital disease mediated by an interlocking and complicated immune network. Self-reactive T cells directly against thyroid-stimulating hormone receptor-bearing orbital fibroblasts contribute to autoimmune inflammation and tissue remodeling in GO orbital connective tissues. To date, T helper (Th) 1 (cytotoxic leaning) and Th2 (antibody leaning) cell subsets and an emerging role of Th17 (fibrotic leaning) cells have been implicated in GO pathogenesis. The potential feedback loops between orbital native residential CD34- fibroblasts, CD34+ infiltrating fibrocytes, and effector T cells may affect the T cell subset bias and the skewed pattern of cytokine production in the orbit, thereby determining the outcomes of GO autoimmune reactions. Characterization of the T cell subsets that drive GO and the cytokines they express may significantly advance our understanding of orbital autoimmunity and the development of promising therapeutic strategies against pathological T cells.

Project description:Background and Objective:A previous study reported alterations in the intestinal microbiota in patients with Graves' orbitopathy (GO). Thyrotropin receptor autoantibody (TRAb) stimulates orbital and periorbital tissues and plays a pivotal role in the development of GO. However, the association between gut microbiota and TRAb in GO patients has still remained elusive. In this study, we explored the relationships between gut microbiota and GO-related traits, in which we applied a metabolic-network-driven analysis to identify GO trait-related modules and extracted significant operational taxonomic units (OTUs). Methods:In the present study, we profiled gut microbiota using 16S rRNA gene sequencing in 31 GO patients. We performed metabolic-network-driven analysis to investigate the association between gut microbiota and GO-related traits (e.g., TRAb, TGAb, and TPOAb) in the combination of microbial effects. Results:Applying microbiome network analysis of cooccurrence patterns and analysis of topological properties, we found that s_Prevotella_copri and f_Prevotellaceae showed a significant correlation with TRAb. In particular, we applied the latent class model to explore the association between gut microbiota and GO-related traits in the combination of microbial effects. It was revealed that the subjects involved in the latent class model with the higher abundance of s_Prevotella_copri and g_Bacteroides had a higher TRAb level. Conclusions:Our results revealed the potential relationships between gut microbiota and GO-related traits in the combination of microbial effects. This study may provide a new insight into the interaction between the intestinal microbiota and TRAb-associated immune responses in GO patients.

Project description:OBJECTIVES:There is a general belief that Graves' orbitopathy (GO) is a "chronic" disease, namely that patients' eyes do not return to how they were before GO appeared. Here, we investigate this issue from both the patient's and the physician's point of view. STUDY DESIGN:We studied the disappearance of GO, regardless of treatment, in all consecutive patients with a GO history of at least 10 years who came for a follow-up visit over a period of 5 years. Patients underwent an ophthalmological examination and were asked to answer a questionnaire on self-perception related to GO. RESULTS:We studied 99 consecutive patients with a GO duration ?10 years. Between the first and the last observation, patients received several types of treatment for their thyroid disease and/or for GO. At the end of follow-up, GO was considered disappeared based on objective criteria in 8 patients (?8%) and based on subjective criteria in 24 patients (?24%). When we considered both subjective and objective criteria, only 2 patients (?2%) had all criteria fulfilled and could be considered as GO-free. CONCLUSIONS:GO is a chronic disease in the vast majority of patients. Even after a very long time since its onset, complete disappearance is rare, although a minority of patients believe they do not have GO anymore and an even lower proportion do not have relevant GO signs. Our findings have obvious implications in patient management and counseling.

Project description:BackgroundGraves' orbitopathy (GO) as well as Graves' disease (GD) hyperthyroidism originate from an autoimmune reaction against the common auto-antigen, thyroid-stimulating hormone receptor (TSHR). GO phenotype is associated with environmental risk factors, mainly nicotinism, as well as genetic risk factors which initiate an immunologic reaction. In some patients GO is observed before diagnosis of GD hyperthyroidism, while it can also be observed far after diagnosis. The intensity of GO symptoms varies greatly in these patients. Thus, the pathogenesis of GD and GO may correlate with different genetic backgrounds, which has been confirmed by studies of correlations between GO and polymorphisms in cytokines involved in orbit inflammation. The aim of our analysis was to assess genetic predisposition to GO in young patients (age of diagnosis ?30 years of age), for whom environmental effects had less time to influence outcomes than in adults.Methods768 GD patients were included in the study. 359 of them had clinically evident orbitopathy (NOSPECS ?2). Patients were stratified by age at diagnosis. Association analyses were performed for genes with a known influence on development of GD - TSHR, HLA-DRB1, cytotoxic T-lymphocyte antigen 4 (CTLA4) and lymphoid protein tyrosine phosphatase (PTPN22).ResultsThe rs179247 TSHR polymorphism was associated with GO in young patients only. In young GO-free patients, allele A was statistically more frequent and homozygous carriers had a considerable lower risk of disease incidence than patients with AG or GG genotypes. Those differences were not found in either elderly patients or the group analyzed as a whole.ConclusionsAllele A of the rs179247 polymorphism in the TSHR gene is associated with lower risk of GO in young GD patients.
