Physician-Perceived Impact of Thyroid Eye Disease on Patient Quality of Life in the United States

Teprotumumab Improves Quality of Life in Thyroid Eye Disease: Meta-analysis and Matching-adjusted Indirect Comparison

Context

Teprotumumab and/or intravenous methylprednisolone (IVMP) are first-line treatments for thyroid eye disease (TED)/Graves' orbitopathy. Direct comparisons of these treatments on Graves' Orbitopathy Quality of Life Questionnaire (GO-QoL) are lacking.

Objective

Systematic review, meta-analysis, and matching-adjusted indirect treatment comparison (MAIC) of GO-QoL improvements.

Methods

A literature search was performed using PubMed and Embase between inception to April 1, 2023, including studies of patients with moderate to severe active TED treated with teprotumumab or IVMP.Changes in GO-QoL scores and appearance and visual function subscales were extracted. Two teprotumumab (n = 84) and placebo (n = 87) randomized clinical trials and 5 studies with IVMP (4.5 mg/12 weeks, n = 304) were identified. MAIC compared teprotumumab/placebo by adjusting for baseline GO-QoL, diplopia, proptosis, smoking, age, and sex. Significant improvements in overall GO-QoL were observed for teprotumumab vs IVMP [mean difference (MD): 13.26; 95% confidence interval (CI): 7.44, 19.09) and placebo (MD: 12.57; 95% CI: 5.94, 19.21), but not IVMP vs placebo (MD: -2.06; 95% CI: -8.24, 4.12). Improvements were noted in appearance subscale GO-QoL for teprotumumab vs IVMP (MD: 7.50; 95% CI: 0.35, 14.64) and placebo (MD: 10.80; 95% CI: 3.62, 17.98) but not for IVMP vs placebo (MD: 0.91; 95% CI: -6.36, 8.18). Visual subscale GO-QoL displayed greater improvements for teprotumumab vs IVMP (MD: 17.66; 95% CI: 7.86, 27.47) and placebo (MD: 14.54; 95% CI: 6.10, 22.99), with no significant change for IVMP vs placebo (MD: -3.65; 95% CI: -12.88, 5.57). Orbital pain, teprotumumab treatment, diplopia, proptosis, and male sex were significant independent predictors of overall GO-QoL (P < .05).

Conclusion

This unique analysis demonstrated a more clinically meaningful improvement in the health-related quality of life, as measured by the GO-QoL, for TED patients with teprotumumab vs both the most recommended IVMP dosage and placebo.

The burden of illness in thyroid eye disease: current state of the evidence

Introduction

Thyroid eye disease (TED) is a disabling autoimmune condition characterized by proptosis and progressive orbital inflammation involving the extraocular muscles, orbital fat, and connective tissues. Clinical features include facial disfigurement, diplopia, dry eyes, and in severe cases, vision loss. Consequently, individuals with TED suffer significant physical and psychological burdens that impact their quality of life. Currently, there is no standardized definition or International Classification of Diseases code for TED, and the disease landscape remains incompletely understood; moreover, TED diagnostic criteria and treatment recommendations have not been thoroughly assessed across diverse populations. It is necessary to better understand the clinical, humanistic, and economic burden of TED and identify gaps in our knowledge to improve TED management and outcomes.

Methods

To describe the current understanding of TED epidemiology, diagnosis, disease burden, and recent TED treatment guidelines, a targeted literature review was conducted, searching multiple databases using key words of specific search topics (i.e., TED; epidemiology, humanistic, economic, and clinical burden; treatment; and practice guidelines) for articles published between October 2013 and October 2023 in the United States, United Kingdom, and Europe (France, Germany, Italy, and Spain). Articles published between May 2014 and May 2024 describing diverse racial and sociodemographic presentations of TED were included.

Results

TED is a complex disease with an array of risk factors, including thyroid dysfunction, thyroid-stimulating immunoglobin, smoking, and comorbid conditions. The natural history of TED is not clearly defined, and diagnosis is complicated due to the array of phenotypes and orbital symptoms observed. Although novel first-line treatments are available in select countries, there is an unmet need for improved treatments for moderate-to-severe and sight-threatening TED. Individuals with TED continue to experience poor health-related quality of life due to the clinical burden that TED imposes along with large healthcare resource utilization costs and treatment costs, and economic evaluation studies are limited. Importantly, there is still a need for studies that explore diverse populations and the impact of race and ethnicity on the disease landscape.

Conclusion

TED remains an incompletely characterized disease with major knowledge gaps, particularly among historically underserved populations.

Investigating factors influencing quality of life in thyroid eye disease: insight from machine learning approaches

Aims

Thyroid eye disease (TED) is an autoimmune orbital disorder that diminishes the quality of life (QOL) in affected individuals. Graves' ophthalmopathy (GO)-QOL questionnaire effectively assesses TED's effect on patients. This study aims to investigate the factors influencing visual functioning (QOL-VF) and physical appearance (QOL-AP) scores in Chinese TED patients using innovative data analysis methods.

Methods

This cross-sectional study included 211 TED patients whose initial visit to our clinic was from July 2022 to March 2023. Patients with previous ophthalmic surgery or concurrent severe diseases were excluded. GO-QOL questionnaires, detailed medical histories and clinical examinations were collected. The distribution of GO-QOL scores was analyzed, and linear regression and machine learning algorithms were utilized.

Results

The median QOL-VF and QOL-AP scores were 64.29 and 62.5, respectively. Multivariate linear regression analysis revealed age (P = 0.013), ocular motility pain (P = 0.012), vertical strabismus (P < 0.001) and diplopia scores as significant predictors for QOL-VF. For QOL-AP, gender (P = 0.013) and clinical activity (P = 0.086) were significant. The XGBoost model demonstrated superior performance, with an R2 of 0.872 and a root mean square error of 11.083. Shapley additive explanations (SHAP) analysis highlighted the importance of vertical strabismus, diplopia score and age in influencing QOL-VF and age, clinical activity and sex in QOL-AP.

Conclusion

TED significantly affects patient QOL. The study highlights the efficacy of XGBoost and SHAP analyses in identifying key factors influencing the QOL in TED patients. Identifying effective interventions and considering specific demographic characteristics are essential to improving the QOL of patients with TED.

CT-based artificial intelligence prediction model for ocular motility score of thyroid eye disease

PURPOSE

Thyroid eye disease (TED) is the most common orbital disease in adults. Ocular motility restriction is the primary complaint of patients, while its evaluation is quite difficult. The present study aimed to introduce an artificial intelligence (AI) model based on orbital computed tomography (CT) images for ocular motility score.

METHODS

A total of 410 sets of CT images and clinical data were obtained from the hospital. To build a triple classification predictive model for ocular motility score, multiple deep learning models were employed to extract features of images and clinical data. Subgroup analyses based on pertinent clinical features were performed to test the efficacy of models.

RESULTS

The ResNet-34 network outperformed Alex-Net and VGG16-Net in prediction of ocular motility score, with the optimal accuracy (ACC) of 0.907, 0.870, and 0.890, respectively. Subgroup analyses indicated no significant difference in ACC between active or inactive phase, functional visual field diplopia or peripheral visual field diplopia (p > 0.05). However, in the gender subgroup, the prediction model performed more accurately in female patients than males (p = 0.02).

CONCLUSION

In conclusion, the AI model based on CT images and clinical data successfully realized automatic scoring of ocular motility in TED patients. This approach potentially enhanced the efficiency and accuracy of ocular motility evaluation, thus facilitating clinical application.

Otolaryngologist surgical preferences for orbital decompression in thyroid eye disease: A North American survey

Background

Orbital decompression is recommended for TED especially in the treatment of severe, refractory cases yet there are no clear guidelines regarding the optimal surgical approach. Previously conducted surveys assessed variations in the management of TED but only amongst ophthalmologists. Our study attempts to better characterize surgical and perioperative preferences amongst otolaryngologists in the management of TED.

Methods

A survey was administered to the American Rhinologic Society and Canadian Society of Otolaryngology - Head and Neck Surgery via REDCap with 52 total respondents. Respondent demographic information and pre-operative management, procedural specifics, and post-operative management preferences were collected.

Results

The majority of respondents practiced in a metropolitan (82.7%), academic setting (73.1%) and received subspecialty training in Rhinology & Skull Base Surgery (88.9%). Most elected for corticosteroids (63.5%) and medical management (69.2%) prior to orbital decompression but did not use any classification system (86.5%). Orbital decompression was most often done with ophthalmology collaboration (71.2%). Removal of two bony walls (55.8%) via medial wall (97.9%) and orbital floor (72.3%) removal was most preferred. Removal of one orbital fat aspect (60.6%) via the medial fat pad was most preferred. Combined bone and fat removal (59.6%) completed via an endoscopic approach (71.2% and 97.0%, respectively) was most common. Post-operatively, most patients were not admitted (88.4%) with saline nasal rinses (92.3%) utilized by most respondents.

Conclusions

This survey completed by otolaryngologists highlights several key distinctions in the preferred surgical approach during orbital decompression and the perioperative management of TED when compared to ophthalmologists and current recommendations.

Level of evidence

Level 4.

Psychological aspects of Graves' ophthalmopathy

Purpose

This review aims to discuss the psychological aspects of Graves' ophthalmopathy (GO), estimate the prevalence of depression and anxiety disorders in GO, examine whether these psychiatric disorders are more prevalent in GO than in Graves' disease (GD) without eye disease, and evaluate the main contributors for depression and anxiety in GO.

Methods

A review of the literature.

Results

Both depression and anxiety are associated with GO. The prevalence of depression and anxiety disorders specifically in GO patients was estimated at 18-33% and 26-41%, respectively. The reported prevalence in GD patients ranged from 9% to 70% for depression and from 18% to 88% for anxiety disorders. Significantly higher levels of depression and anxiety were found in GD patients compared with patients with non-autoimmune hyperthyroidism. Conflicting results have been reported regarding the association of antithyroid autoantibodies with depression and anxiety disorders. Serum thyroid hormone levels do not correlate with the severity of depression and anxiety. An improvement of psychiatric symptoms is observed in hyperthyroid patients after treatment of thyrotoxicosis. Moreover, depression and anxiety are significantly related to impaired quality of life (QoL) in GO. Exophthalmos and diplopia were not associated with depression nor anxiety, but orbital decompression and strabismus surgery do seem to improve QoL in GO patients.

Conclusions

The results of this review suggest that altered thyroid hormone levels and autoimmunity are prognostic factors for depression and anxiety in GO. With regard to the visual and disfiguring aspects of GO as contributing factors for depression and anxiety, no decisive conclusions can be made.

Long-Term Efficacy of Teprotumumab in Thyroid Eye Disease: Follow-Up Outcomes in Three Clinical Trials

Introduction: Thyroid eye disease (TED) is an autoimmune process characterized by extraocular muscle and orbital fat remodeling/expansion resulting in swelling, pain, redness, proptosis, and diplopia. Teprotumumab, an insulin-like growth factor-I receptor inhibitor, demonstrated improvements in TED signs and symptoms in three adequately powered clinical trials of 24 weeks duration. Here we analyze the long-term maintenance of responses with teprotumumab from these trials. Methods: A total of 112 patients who received 7 or 8 infusions of teprotumumab in the Phase 2, Phase 3 (OPTIC study), and OPTIC Extension (OPTIC-X) studies were included in this analysis. Responses, including clinical activity score (CAS ≥2-point improvement), the European Group of Graves' Orbitopathy ophthalmic composite outcome, diplopia (≥1 Gorman grade improvement), proptosis (≥2 mm improvement), Overall (improvement in proptosis + CAS), and disease inactivation (CAS ≤1), were assessed and pooled from study baseline to week 24 (formal study) and up to week 72 (formal follow-up). Graves' Ophthalmopathy quality-of-life (GO-QoL) scores were also assessed. Outcomes included the percentages of observed patient responses from the study baseline. Additional alternative treatments for TED were assessed as a surrogate of persistent benefit from week 24 through week 120 (extended follow-up). Studies differed in the timing of follow-up visits, and data from some visits were unavailable. Results: At week 72, 52/57 (91.2%), 51/57 (89.5%), 35/48 (72.9%), 38/56 (67.9%), and 37/56 (66.1%) of patients were responders for CAS, composite outcome, diplopia, proptosis, and Overall response, respectively. The mean reduction in proptosis was 2.68 mm (SD 1.92, n = 56), mean GO-QoL improvement was 15.22 (SE 2.82, n = 56), and disease inactivation (CAS ≤1) was detected in 40/57 (70.2%). Over 99 weeks following teprotumumab therapy, 19/106 (17.9%) patients reported additional TED therapy during formal and extended follow-up. Conclusion: The long-term response to teprotumumab as observed 51 weeks after therapy was similar to week 24 results in the controlled clinical trials. Inflammatory and ophthalmic composite outcome improvements were seen in 90% of patients with nearly 70% reporting improvement in diplopia and proptosis. Further, 82% of patients in this analysis did not report additional TED treatment (including surgery) over 99 weeks following the final teprotumumab dose.

Differentially expressed genes in orbital adipose/connective tissue of thyroid-associated orbitopathy

Background

Thyroid-associated orbitopathy (TAO) is a disease associated with autoimmune thyroid disorders and it can lead to proptosis, diplopia, and vision-threatening compressive optic neuropathy. To comprehensively understand the molecular mechanisms underlying orbital adipogenesis in TAO, we characterize the intrinsic molecular properties of orbital adipose/connective tissue from patients with TAO and control individuals.

Methods

RNA sequencing analysis (RNA-seq) was performed to measure the gene expression of orbital adipose/connective tissues of TAO patients. Differentially expressed genes (DEGs) were detected and analyzed through Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis, and Gene Set Enrichment Analysis (GSEA). The protein-protein interaction (PPI) network was constructed using the STRING database, and hub genes were identified by the Cytoscape plug-in, cytoHubba. We validated several top DEGs through quantitative real-time polymerase chain reaction (qRT-PCR).

Results

We identified 183 DEGs in adipose tissue between TAO patients (n = 3) and control patients (n = 3) through RNA sequencing, including 114 upregulated genes and 69 downregulated genes. The PPI network of these DEGs had 202 nodes and 743 edges. PCR-based validation results of orbital adipose tissue showed multiple top-ranked genes in TAO patients (n = 4) are immune and inflammatory response genes compared with the control individual (n = 4). They include ceruloplasmin isoform x3 (CP), alkaline tissue-nonspecific isozyme isoform x1 (ALPL), and angiotensinogen (AGT), which were overrepresented by 2.27- to 6.40-fold. Meanwhile, protein mab-21-like 1 (MAB21L1), phosphoinositide 3-kinase gamma-subunit (PIK3C2G), and clavesin-2 (CLVS2) decreased by 2.6% to 32.8%. R-spondin 1 (RSPO1), which is related to oogonia differentiation and developmental angiogenesis, was significantly downregulated in the orbital muscle tissues of patients with TAO compared with the control groups (P = 0.024).

Conclusions

Our results suggest that there are genetic differences in orbital adipose-connective tissues derived from TAO patients. The upregulation of the inflammatory response in orbital fat of TAO may be consistent with the clinical phenotype like eyelid edema, exophthalmos, and excess tearing. Downregulation of MAB21L1, PIK3C2G, and CLVS2 in TAO tissue demonstrates dysregulation of differentiation, oxidative stress, and developmental pathways.

How patients experience thyroid eye disease

Objective

To determine the impact of thyroid eye disease (TED) on patients in various stages of the disease.

Background

TED is a debilitating and potentially sight-threatening inflammatory autoimmune disease that is frequently misdiagnosed. Challenging quality-of-life (QoL) issues can persist long after the active phase of disease has subsided.

Methods

A 62-question survey was designed as a hypothesis-generating instrument to identify key issues confronting patients ≥18 years old with physician-diagnosed TED. Questions focused primarily on physical and emotional status, and QoL experiences in the 2 months prior to the survey. Data for individual questions are presented as summary statistics. Correlations between questions were determined using χ2 analyses.

Results

The 443 respondents were 18 to >80 years old; >90% female, and >80% from the United States. Time since TED diagnosis ranged from <1 year to >10 years. Participants provided >500 free-form responses describing experiences of living with TED. Physical signs/symptoms were experienced by 307/443 (69%) patients. Of those responding to the QoL questions (N = 394), 53 (13%) reported symptoms improving, 73 (19%) reported symptoms worsening, and 255 (65%) reported no change in the 2 months prior to the survey. The most bothersome signs/symptoms were dry/gritty eyes, light sensitivity, bulging eyes, and pressure or pain behind the eyes. Respondents <60 years were significantly (p < 0.0001) more likely to report symptomatic TED than older patients. Of 394 respondents, 179 (45%) reported feeling depressed and/or anxious, 174 (44%) reported concern about their appearance, and 73 (19%) avoided public situations; 192 (49%) reported declines in confidence or feelings of general well-being, and 78 (20%) reported an inability to achieve goals. Activities limited by TED included reading, driving, and socializing. The proportion of respondents experiencing these negative QoL measures was higher when patients reported experiencing >5 symptoms, had been diagnosed within the last 5 years, or were <60 years of age.

Conclusions

Physical manifestations of TED impact QoL for patients through all phases of the disease. It is essential that physicians and healthcare professionals become more familiar with patient experiences such as those described here to better help patients manage their disease.

Evaluation of Depression and Anxiety in a Diverse Population With Thyroid Eye Disease Using the Nationwide NIH All of Us Database

PURPOSE

To evaluate the prevalence of depression and anxiety among individuals with thyroid eye disease (TED) and identify sociodemographic risk factors using the NIH All of Us database.

METHODS

Three hundred ninety eight cases with TED were compared with 1,592 controls with demographics matching the 2020 US Census. Primary outcomes were diagnosed depression or anxiety; Patient Health Questionnaire-9 (PHQ-9) scores and General Anxiety Disorder-7 (GAD-7) scores were included as secondary outcomes. We performed multivariable logistic regression to generate odds ratios (ORs) and 95% confidence intervals (CIs) for the association between TED and depression and anxiety.

RESULTS

Patients with TED were more likely to have depression (OR 2.72, 95% CI 2.08-3.56, p < 0.001) and anxiety (OR 2.82, 95% CI 2.16-3.70, p < 0.001) than controls. In patients with TED, female gender was an independent risk factor for both depression (OR 1.72; 95% CI 1.00-5.07, p = 0.05) and anxiety (OR 2.17, 95% CI 1.25-3.85, p = 0.006). Unemployment (OR 1.72, 95% CI 1.03-2.94, p = 0.04) and lower income (OR 0.88 for income as a continuous variable, 95% CI 0.79-0.99, p = 0.03) were risk factors for anxiety. Risk factors for more severe depression as assessed by PHQ-9 included lower income (OR 0.70, 95% CI 0.57-0.85, p < 0.001), and protective factors included Black race (OR 0.12, 95% CI 0.02-0.45, p = 0.002). Lower income was associated with more severe anxiety as assessed by GAD-7 (OR 0.77, 95% CI 0.64-0.94, p = 0.009).

CONCLUSIONS

Patients with TED were more likely to develop depression and anxiety compared with controls. This study highlights the psychosocial impact of TED and associated socioeconomic risk factors.

Impact of hyperthyroidism and its treatment on the outcome of mental health, occupational functioning, and quality of life: A naturalistic, prospective study

Context Background

Hyperthyroidism has a major impact on mental health.

Aims

We intended to determine the magnitude of the unmet need for mental health support in patients with hyperthyroidism attending an endocrinology clinic.

Settings and Design

General Hospital Endocrine Department, Prospective Study.

Methods and Material

In a naturalistic, prospective study, consecutive (n = 176) hyperthyroid patients were assessed for anxiety (generalized anxiety disorder, GAD-7), depression (Patient Health Questionnaire PHQ-9), functional impairment (work and social adjustment scale, WSAS), and quality of life (EuroQol ED5D) using standardized instruments.

Statistical Analysis Used

Percentages, mean and standard deviation (SD), Chi-square, Student's t-test, ANOVA, Spearman's correlation.

Results

A considerable proportion (40.5%) of patients had moderate and severe anxiety, around half (50.6%) had moderate or severe depression, and 20.8% had severe functional impairment at presentation. Mean EQ5D score was 59.6 ± 23.5. The scores of anxiety, depression, and functional impairment were significantly correlated with each other and negatively correlated with QOL. Following treatment of hyperthyroidism, improvement in psychiatric symptoms was noted which could be correlated with the lowering of T4. However, a significant proportion of patients continued to have psychiatric symptoms and functional impairment despite achieving euthyroidism. There was no correlation between the severity of hyperthyroidism to persistence of mental health parameters.

Conclusions

Our findings of high prevalence and persistence of impairment of mental health and functional status of patients with hyperthyroidism have highlighted the unmet needs for these patients.

Update on the surgical management of Graves' orbitopathy

Graves' orbitopathy (GO) is a complex autoimmune disorder of the orbit that causes the eye to appear disfigured. GO is typically associated with Graves' disease, an inflammatory autoimmune condition that is caused by thyrotropin receptor autoantibodies. Although our knowledge of the pathophysiology of GO has improved, its exact pathogenesis remains unclear. Some patients suffer from disfigurement, double vision, and even vision loss rather than hyperthyroidism. The disease severity and activity prompt different treatments, as the signs of GO are heterogeneous, so their management can be very complex. Despite medical advances, the first-line treatment for moderate-to-severe active GO is still glucocorticoids, while surgery can be critical for the treatment of chronic inactive GO. Surgery is sometimes required in the acute phase of the disease when there is an immediate risk to vision, such as in dysthyroid optic neuropathy. Most surgeries for GO are rehabilitative and subdivided into three categories: decompression, strabismus repair, and lid surgery. This review is a basic overview of the field, with up-to-date knowledge of the surgical techniques for GO. We review and summarize recent literature on the advances in surgery for GO to provide up-to-date insights on the optimal surgical treatment for GO.

Management of Thyroid Eye Disease: A Consensus Statement by the American Thyroid Association and the European Thyroid Association

Thyroid eye disease (TED) remains challenging for clinicians to evaluate and manage. Novel therapies have recently emerged, and their specific roles are still being determined. Most patients with TED develop eye manifestations while being treated for hyperthyroidism and under the care of endocrinologists. Endocrinologists, therefore, have a key role in diagnosis, initial management, and selection of patients who require referral to specialist care. Given that the need for guidance to endocrinologists charged with meeting the needs of patients with TED transcends national borders, and to maximize an international exchange of knowledge and practices, the American Thyroid Association and European Thyroid Association joined forces to produce this consensus statement.

Nationwide Incidence of Thyroid Eye Disease and Cumulative Incidence of Strabismus and Surgical Interventions in Denmark

Importance

Thyroid eye disease (TED) is a serious condition that can cause proptosis and strabismus and, in rare cases, lead to blindness. Incidence data for TED and strabismus and surgical interventions after TED are sparce.

Objective

To investigate the nationwide incidence of TED, strabismus, and surgical interventions associated with TED.

Design, Setting, and Participants

A Danish nationwide registry-based cohort study between 2000, which marks the beginning of uniform coding for the decompression surgery nationwide, and 2018. The cohort consisted of a mean 4.3 million people aged 18 to 100 years with no prior TED diagnosis each year. Total observation time was 8.22 × 107 person-years (women, 4.18 × 107 person-years; men, 4.04 × 107 person-years).

Main Outcome Measures

The annual numeric and age-standardized incidence of hospital-treated TED and cumulative incidence of strabismus, strabismus surgery, and orbital decompression surgery in patients with TED. The incidence was stratified by sex, thyroid diagnosis, and age.

Results

A total of 4106 incident diagnoses of TED were identified during 19 years among 3344 women (81.4%) and 762 men (18.6%). The mean numeric annual nationwide incidence rate of TED was 5.0 per 100 000 person-years overall, 8.0 per 100 000 person-years in women, and 1.9 per 100 000 person-years in men, resulting in a 4:1 ratio of women to men with TED. The age-standardized incidence was similar. The mean (SD) age at onset was 51.3 (14.5) years. At the time of TED diagnosis, 611 patients (14.9%) were euthyroid, 477 (11.6%) were hypothyroid, and 3018 (73.5%) were hyperthyroid. In patients with TED who were euthyroid, the 4-year cumulative incidence was 41% for antithyroid medication and 13% for L-thyroxine. In patients with TED, the 4-year cumulative incidence for strabismus was 10%. The 4-year cumulative incidence of surgical interventions after TED was 8% for strabismus surgery and 5% for orbital decompression. At 4 years, strabismus surgery was more common in men (13.3%; 95% CI, 10.75-15.86) than in women (7.2%; 95% CI, 6.24-8.08), and the absolute difference was 6.1% (95% CI, 3.42-8.14; P < .001).

Conclusions and Relevance

This study in Denmark provides nationwide empirical incidence of TED and strabismus and surgical interventions after TED that required inpatient or outpatient hospital treatment, and might be used for patient information and health care planning.

Thinking inside the box: Current insights into targeting orbital tissue remodeling and inflammation in thyroid eye disease

Thyroid eye disease (TED) is an autoimmune disorder that manifests in the orbit. In TED, the connective tissue behind the eye becomes inflamed and remodels with increased fat accumulation and/or increased muscle and scar tissue. As orbital tissue expands, patients develop edema, exophthalmos, diplopia, and optic neuropathy. In severe cases vision loss may occur secondary to corneal scarring from exposure or optic nerve compression. Currently there is no cure for TED, and treatments are limited. A major breakthrough in TED therapy occurred with the FDA approval of teprotumumab, a monoclonal insulin-like growth factor 1 receptor (IGF1R) blocking antibody. Yet, teprotumumab therapy has limitations, including cost, infusion method of drug delivery, variable response, and relapse. We describe approaches to target orbital fibroblasts and the complex pathophysiology that underlies tissue remodeling and inflammation driving TED. Further advances in the elucidation of the mechanisms of TED may lead to prophylaxis based upon early biomarkers as well as lead to more convenient, less expensive therapies.

The prevalence of anxiety symptoms and disorders among ophthalmic disease patients

Background:

Progressive and irreversible vision loss has been shown to place a patient at risk of mental health problems such as anxiety. However, the reported prevalence of anxiety symptoms and disorders among eye disease patients vary across studies. Thus, this study aims to clarify the estimated prevalence of anxiety symptoms and disorders among ophthalmic disease patients.

Methods:

Relevant studies on the prevalence of anxiety symptoms and disorders among eye disease patients were collected through international databases, PubMed, Scopus, and Web of Science. A random-effects model was used to determine the pooled prevalence of anxiety symptoms and disorders among ophthalmic disease patients.

Results:

The 95 included studies yielded a pooled prevalence of 31.2% patients with anxiety symptoms and 19.0% with anxiety disorders among subjects with ophthalmic disease. Pediatric patients were more anxious (58.6%) than adults (29%). Anxiety symptoms were most prevalent in uveitis (53.5%), followed by dry eye disease (DED, 37.2%), retinitis pigmentosa (RP, 36.5%), diabetic retinopathy (DR, 31.3%), glaucoma (30.7%), myopia (24.7%), age-related macular degeneration (AMD, 21.6%), and cataract (21.2%) patients. Anxiety disorders were most prevalent in thyroid eye disease (TED, 28.9%), followed by glaucoma (22.2%) and DED (11.4%). When compared with healthy controls, there was a twofold increase on the prevalence of anxiety symptoms (OR = 1.912, 95% CI 1.463–2.5, p < 0.001) and anxiety disorders (OR = 2.281, 95% CI 1.168–4.454, p = 0.016).

Conclusion:

Anxiety symptoms and disorders are common problems associated with ophthalmic disease patients. Thus, comprehensive and appropriate treatments are necessary for treating anxiety symptoms and disorders among ophthalmic disease patients.

Quality of Life in Patients with Chronic Thyroid Eye Disease in the United States

INTRODUCTION

Thyroid eye disease (TED) is an autoimmune condition producing ocular pain, dysmotility, and ocular structure and function changes. As disease activity changes, redness, swelling, and pain can improve, but eye comfort, appearance, and motility alterations often persist. There are limited data on chronic TED patient-reported outcomes. This study examined chronic US TED patient-reported symptoms and quality of life (QOL).

METHODS

Existing data from an online survey regarding chronic TED signs/symptoms and patient QOL were retrospectively examined. The Graves' Ophthalmopathy QOL instrument (GO-QOL; 0-100, 100 = highest QOL) evaluated overall, appearance, and vision-related QOL. Influencing factors were examined by stratifying patients into low (overall QOL ≤ 50), moderate (> 50 and < 75), and high (≥ 75) QOL categories.

RESULTS

One hundred patients (47 women, 81 Caucasian, 45.2 ± 7.6 years) were included. The duration of inactive TED was 3.0 ± 4.6 years and total duration of TED was 5.8 ± 5.9 years. Patients reported an average of 20 doctor visits/year and high prevalence of anxiety (34%) and depression (28%). Prior TED treatments for the polled population included systemic corticosteroids during active TED (25%), orbital radiation (5%), and surgery (25%). The overall GO-QOL score was 60.5 ± 21.8 (vision-related: 58.6 ± 24.0, appearance-related: 62.3 ± 25.1). Patients with low QOL more frequently reported hypothyroidism, anxiety, and a larger number of chronic TED signs/symptoms (average: 4.2). Compared to high QOL patients, low QOL patients had more pain (39% vs. 13%), blurry vision (30% vs. 17%), and diplopia (27% vs. 3%, all p ≤ 0.025). Additionally, the low QOL group more often had TED-specific surgical history (45% vs. 10%, p = 0.002), more often reported disability/unemployment (21% vs. 3%, p = 0.055), and had a higher number of doctor visits (40 vs. 5 visits/person/year, p < 0.001).

CONCLUSION

TED severely impacts patient QOL, despite becoming stable and chronic. Patients reported vision and appearance impairment and psychosocial impact long after acute TED had subsided.

Teprotumumab for thyroid eye disease: early response is not required for benefit

Purpose

In recent trials, 50% of patients treated with teprotumumab for thyroid eye disease had significant improvements in proptosis at 6 weeks. However, a small subgroup of patients did not have a significant response by week 12. We examine the outcomes at week 24 in patients from both trials who had little or no proptosis response at week 12.

Design

In this post hoc analysis, data from teprotumumab-treated patients in the placebo-controlled randomized phases 2 and 3 trials were reviewed.

Methods

Patients treated with teprotumumab or placebo with a ≤2 mm reduction from baseline in proptosis at week 12 and completed assessments at both the weeks 12 and 24 visits were included. The main outcome measures were a change in proptosis, clinical activity score (CAS) and diplopia in response to teprotumumab therapy at baseline and weeks 6, 12, 18, and 24.

Results

From the phases 2 and 3 studies, 24 patients from the treated and placebo groups were included for analysis (48 total). In the teprotumumab group, of the 24 who had no improvement in proptosis (≥2 mm from baseline) at 12 weeks, 15 (63%) demonstrated a clinically significant improvement at week 24. No patients from the 24 placebo patients had a clinically significant improvement in proptosis at 12 weeks, and 24 weeks. At week 12, 22 patients (92%) in the teprotumumab group had a significant reduction in the CAS (≥2 points) and at 24 weeks all patients achieved this reduction. At week 12, 11 (46%) patients from the placebo group had a significant improvement, while 10 (42%) had a significant improvement at 24 weeks. 22 of the 24 patients (92%) in the teprotumumab group had a diplopia grade > 0 at baseline. At week 12, 12 of the 22 (55%) had improvement in diplopia ≥ 1 grade. By week 24, 16 patients (73%) had an improvement in diplopia ≥ 1 grade. In the placebo group, 15 (63%) had significant diplopia. At week 12, 3 (20%) from this group had improvement in diplopia ≥ 1 grade, while at 24 weeks this number rose to 4 (27%).

Conclusions

There is variability in the time taken to manifest a clinically significant response to teprotumumab, some patients my need a longer time to respond.
