RESUMEN

PURPOSE: To assess the duration, incidence, reversibility, and severity of adverse events (AEs) in patients with thyroid eye disease (TED) treated with teprotumumab. DESIGN: Multicenter, retrospective, observational cohort study. PARTICIPANTS: Patients with TED of all stages and activity levels treated with at least 4 infusions of teprotumumab. METHODS: Patients were treated with teprotumumab between February 2020 and October 2022 at 6 tertiary centers. Adverse event metrics were recorded at each visit. MAIN OUTCOME MEASURES: The primary outcomes measure was AE incidence and onset. Secondary outcome measures included AE severity, AE reversibility, AE duration, proptosis response, clinical activity score (CAS) reduction, and Gorman diplopia score improvement. RESULTS: The study evaluated 131 patients. Proptosis improved by 2 mm or more in 77% of patients (101/131), with average proptosis improvement of 3.0 ± 2.1 mm and average CAS reduction of 3.2 points. Gorman diplopia score improved by at least 1 point for 50% of patients (36/72) with baseline diplopia. Adverse events occurred in 81.7% of patients (107/131). Patients experienced a median of 4 AEs. Most AEs were mild (74.0% [97/131]), 28.2% (37/131) were moderate, and 8.4% (11/131) were severe. Mean interval AE onset was 7.9 weeks after the first infusion. Mean resolved AE duration was 17.6 weeks. Forty-six percent of patients (60/131) demonstrated at least 1 persistent AE at last follow-up. Mean follow-up was 70.2 ± 38.5 weeks after the first infusion. The most common type of AEs was musculoskeletal (58.0% [76/131]), followed by gastrointestinal (38.2% [50/131]), skin (38.2% [50/131]), ear and labyrinth (30.5% [40/131]), nervous system (20.6% [27/131]), metabolic (15.3% [20/131]), and reproductive system (12.2% [16/131]). Sixteen patients (12.2%) discontinued therapy because of AEs, including hearing loss (n = 4), inflammatory bowel disease flare (n = 2), hyperglycemia (n = 1), muscle spasms (n = 1), and multiple AEs (n = 8). CONCLUSIONS: Adverse events are commonly reported while receiving teprotumumab treatment. Most are mild and reversible; however, serious AEs can occur and may warrant treatment cessation. Treating physicians should inform patients about AE risk, properly screen patients before treatment, monitor patients closely throughout therapy, and understand how to manage AEs should they develop.

RESUMEN

BACKGROUND: Teprotumumab, a novel IGF-1R antibody, has been shown to significantly reduce the signs of acute and chronic Thyroid Eye Disease (TED). Light sensitivity is a reported symptom in patients with TED. There is a lack of a prospective study that has explored the effects on light sensitivity in a large cohort of patients with acute and chronic TED following treatment with teprotumumab. METHODS: Consecutive patients who were diagnosed with TED and reported light sensitivity at baseline were considered for study eligibility. All patients had measurements of Visual Light Sensitivity Questionnaire-8 (VLSQ-8), proptosis, clinical activity score (CAS), and MRD1 (distance between the upper eyelid margin and corneal reflex, mm) and MRD2 (distance between the lower eyelid margin and corneal reflex, mm) before and after treatment. RESULTS: Ninety patients (41 acute, 49 chronic) met the inclusion criteria. The mean (SD) age was 47.3 (14.3). Eighty-six (95.6%) patients completed all 8 infusions. There was a significant reduction in the total score and across all categories of the VLSQ-8 (p <  0.01 for all). Seventy-two (80%) patients had a clinically significant improvement (≥2 reduction) in at least one category. There was no significant difference in the total VLSQ-8 score between the acute and chronic group (p = 0.8). CONCLUSION: Teprotumumab improves light sensitivity in patients with acute and chronic TED. The results of this study highlight that the improvements in light sensitivity following treatment are not directly related to the mechanical changes in TED, suggesting another underlying mechanism is potentially involved.

RESUMEN

BACKGROUND: Thyroid eye disease is a debilitating, disfiguring, and potentially blinding periocular condition for which no Food and Drug Administration-approved medical therapy is available. Strong evidence has implicated the insulin-like growth factor I receptor (IGF-IR) in the pathogenesis of this disease. METHODS: In a randomized, double-masked, placebo-controlled, phase 3 multicenter trial, we assigned patients with active thyroid eye disease in a 1:1 ratio to receive intravenous infusions of the IGF-IR inhibitor teprotumumab (10 mg per kilogram of body weight for the first infusion and 20 mg per kilogram for subsequent infusions) or placebo once every 3 weeks for 21 weeks; the last trial visit for this analysis was at week 24. The primary outcome was a proptosis response (a reduction in proptosis of ≥2 mm) at week 24. Prespecified secondary outcomes at week 24 were an overall response (a reduction of ≥2 points in the Clinical Activity Score plus a reduction in proptosis of ≥2 mm), a Clinical Activity Score of 0 or 1 (indicating no or minimal inflammation), the mean change in proptosis across trial visits (from baseline through week 24), a diplopia response (a reduction in diplopia of ≥1 grade), and the mean change in overall score on the Graves' ophthalmopathy-specific quality-of-life (GO-QOL) questionnaire across trial visits (from baseline through week 24; a mean change of ≥6 points is considered clinically meaningful). RESULTS: A total of 41 patients were assigned to the teprotumumab group and 42 to the placebo group. At week 24, the percentage of patients with a proptosis response was higher with teprotumumab than with placebo (83% [34 patients] vs. 10% [4 patients], P<0.001), with a number needed to treat of 1.36. All secondary outcomes were significantly better with teprotumumab than with placebo, including overall response (78% of patients [32] vs. 7% [3]), Clinical Activity Score of 0 or 1 (59% [24] vs. 21% [9]), the mean change in proptosis (-2.82 mm vs. -0.54 mm), diplopia response (68% [19 of 28] vs. 29% [8 of 28]), and the mean change in GO-QOL overall score (13.79 points vs. 4.43 points) (P≤0.001 for all). Reductions in extraocular muscle, orbital fat volume, or both were observed in 6 patients in the teprotumumab group who underwent orbital imaging. Most adverse events were mild or moderate in severity; two serious events occurred in the teprotumumab group, of which one (an infusion reaction) led to treatment discontinuation. CONCLUSIONS: Among patients with active thyroid eye disease, teprotumumab resulted in better outcomes with respect to proptosis, Clinical Activity Score, diplopia, and quality of life than placebo; serious adverse events were uncommon.

RESUMEN

BACKGROUND: Dry eye syndrome occurs in up to 85% of patients with thyroid eye disease (TED). Lacrimal gland enlargement correlates with subjective tearing and a reduction in quality of life in patients with TED. METHODS: In this prospective longitudinal study, patients presenting for the treatment of TED were considered for eligible. Primary outcomes included a change in the volume of the lacrimal gland and the production of tears following treatment with teprotumumab. The volume of lacrimal glands and proptosis was calculated using 3D volumetric analysis. Tear production was measured by Schirmer's test and associated symptoms were assessed using the VLSQ-8. The orbit with the most proptosis was designated the study orbit and the contralateral orbit was designated the fellow orbit. RESULTS: Twenty patients were included. Mean (SD) age was 61 (18) and mean duration of TED prior to therapy was 48 months (47). Lacrimal gland volume in the study orbit decreased from 768 mm3 (288) to 486 mm3 (173) (p < 0.01) following therapy. For the fellow orbit, volume reduced from 637 mm3 (261) to 379 mm3 (147) (p < 0.01). Schirmer's test reading (STR) in the study orbit increased from 14.5 mm (8.2) to 23 mm (10) (p < 0.01) (59%) following treatment. In the fellow orbit, STR increased from 12.7 mm (7) to 21 mm (9) post therapy (69%) (p < 0.01). There was a significant improvement on all parts of the VLSQ-8. CONCLUSION: Teprotumumab significantly reduces TED related expansion of the lacrimal gland, increases tear production, and improves dry eye symptoms.

RESUMEN

PURPOSE: Teprotumumab, an insulin-like growth factor 1 receptor monoclonal antibody, is FDA-approved to treat thyroid eye disease (TED). The initial clinical trials excluded patients with previous orbital irradiation, surgery, glucocorticoid use (cumulative dose >1 gm), or prior biologic treatment. Information on the use of teprotumumab for patients who failed prior therapy is limited. Our purpose is to characterize the efficacy of teprotumumab for the treatment of recalcitrant TED. METHODS: This is a multicenter retrospective study of all patients treated with teprotumumab for moderate-to-severe TED after failing conventional therapy with corticosteroids, orbital radiation, surgical decompression, biologics, or other steroid-sparing medications. Treatment failure was defined as an incomplete response to or reactivation after previous treatment. Only patients who received at least 4 infusions of teprotumumab were included in the analysis. Primary outcome measures comprised proptosis response (≥2 mm reduction in the study eye without a similar increase in the other eye), clinical activity score (CAS) response (≥2-point reduction in CAS), and diplopia response (≥1 point improvement in Gorman diplopia score in patients with baseline diplopia) following treatment. Adverse events and risk factors for recalcitrant disease were also evaluated. RESULTS: Sixty-six patients were included in this study, 46 females and 20 males. Average age was 59.3 years (range 29-93). The mean duration of disease from TED diagnosis to first infusion was 57.8 months. The proptosis, CAS, and diplopia responses in this recalcitrant patient population were 85.9%, 93.8%, and 69.1%, respectively. Patients experienced a mean reduction in proptosis of 3.1 ± 2.4 mm and a mean improvement in CAS of 3.8 ± 1.6. Patients who underwent prior decompression surgery experienced a statistically significant decrease in diplopia response (46.7% vs. 77.5%, p = 0.014) and proptosis response (75.0% vs. 90.9%, p = 0.045) when compared with nondecompression patients. Additionally, there were no significant differences in proptosis, CAS, and diplopia responses between patients with acute (defined as disease duration <1 year) versus chronic (disease duration ≥1 year) TED. While most adverse events were mild to moderate, 4 patients reported serious adverse events related to persistent hearing loss. CONCLUSIONS: Patients with recalcitrant TED demonstrated a significant improvement after teprotumumab in each of the primary study outcomes. The degree of proptosis reduction, diplopia response, and CAS improvement in the recalcitrant group were similar to those of treatment-naïve patients from the pivotal clinical trials. Patients with a prior history of orbital decompression, however, demonstrated poor improvement in diplopia and less reduction in proptosis than surgery naïve patients. These results indicate that teprotumumab is a treatment option for the treatment of patients with TED recalcitrant to prior medical therapies.

RESUMEN

BACKGROUND: The increasing popularity of fat transfer (FT) to the lower eyelids has led to an increase in unwanted lumps, bumps, and contour irregularities (LBCs). Few studies have addressed the management of LBCs. OBJECTIVES: The aim of this study was to address the management of LBCs. METHODS: In this retrospective review, charts of all patients presenting for evaluation of LBCs following FT procedures to the lower eyelid were reviewed. Clinical characteristics on presentation and surgical findings were evaluated. Patient postoperative clinical course and complications were also documented. RESULTS: Forty-eight patients were included (45 women and 3 men), with an average follow-up of 14 months (range, 5-24 months). In 65%, LBCs manifested above the lower orbital rim (AR) and in 35% they were noted AR and below the rim (AR/BR). The type of contour deficits noted were a solitary nodule (SN) in 54%, a mixed picture (MP) in 23%, diffuse enlargement (DE) in 17%, and multiple nodules (MNs) in 6%. Combining lesion location and type of contour deficit, the most common presentation was an SN-AR in 22 patients (46%), followed by an MP-AR/BR in 8 patients (17%), and a DE-AR/BR in 5 patients (10%). Surgical findings revealed that grafted fat is consistently found separate from native eyelid/orbital fat, and within the orbicularis muscle when AR, and within the orbicularis muscle or the deep suborbicularis oculi fat when BR. CONCLUSIONS: LBCs tend to manifest in characteristic patterns with a predilection for an AR location. Recommendations on the diagnosis and management of these lesions are provided.

RESUMEN

PURPOSE: To evaluate teprotumumab safety/efficacy in patients with thyroid eye disease (TED) who were nonresponsive or who experienced a disease flare. DESIGN: The Treatment of Graves' Orbitopathy to Reduce Proptosis with Teprotumumab Infusions in an Open-Label Clinical Extension Study (OPTIC-X) is a teprotumumab treatment and re-treatment trial following the placebo-controlled teprotumumab Phase 3 Treatment of Graves' Orbitopathy (Thyroid Eye Disease) to Reduce Proptosis with Teprotumumab Infusions in a Randomized, Placebo-Controlled, Clinical Study (OPTIC) trial. PARTICIPANTS: Patients who previously received placebo (n = 37) or teprotumumab (n = 14) in OPTIC. METHODS: OPTIC nonresponders or those who flared (≥2-mm increase in proptosis, ≥2-point increase in clinical activity score [CAS], or both) during follow-up were treated for the first time (previous placebo patients) or re-treated with teprotumumab in OPTIC-X with 8 infusions over 24 weeks. MAIN OUTCOME MEASURES: Proptosis response and safety. Secondary outcomes included proptosis, CAS, subjective diplopia, and quality-of-life. RESULTS: Thirty-three of 37 placebo-treated OPTIC patients (89.2%) became proptosis responders (mean ± standard deviation, -3.5 ± 1.7 mm) when treated with teprotumumab in OPTIC-X. The responses were equivalent to the OPTIC study. In these responders, proptosis, CAS of 0 or 1, and diplopia responses were maintained in 29 of 32 patients (90.6%), 20 of 21 patients (95.2%), and 12 of 14 patients (85.7%), respectively, at follow-up week 48. The median TED duration was 12.9 months versus 6.3 months in those treated with teprotumumab in the OPTIC study. Of the 5 OPTIC teprotumumab nonresponders re-treated in OPTIC-X, 2 responded, 1 showed a proptosis reduction of 1.5 mm from OPTIC baseline, and 2 discontinued treatment early. Of the OPTIC teprotumumab responders who experienced flare, 5 of 8 patients (62.5%) responded when re-treated (mean proptosis reduction, 1.9 ± 1.2 mm from OPTIC-X baseline and 3.3 ± 0.7 mm from OPTIC baseline). Compared with published double-masked trials and their integrated follow-up, no new safety signals were identified. Mild hearing impairment was reported; 4 events occurred during the first course of treatment, and 2 events reoccurred after re-treatment. CONCLUSIONS: Patients with TED of longer disease duration responded similarly to those treated earlier in the disease course. Patients with an insufficient initial response or flare may benefit from additional teprotumumab therapy. No new safety risk was identified; however additional postmarketing pharmacovigilance is ongoing.

RESUMEN

OBJECTIVE: Thyroid eye disease (TED) is an autoimmune, inflammatory disease resulting in retro-orbital fat and extraocular muscle expansion. TED quiets ("inactivates") as inflammation wanes; however, signs/symptoms often persist. Signs/symptoms of the disease and the impact on quality of life (QoL) were examined in noninflammatory and inflammatory TED. METHODS: Data of patients with moderate-to-severe TED were collected from treating physicians. Clinical activity score (CAS, 6/7 measures available) was used to classify TED as inflammatory (CAS ≥ 3) or noninflammatory (CAS = 0 or 1). QoL impact was scored as 1 = "not at all impaired" to 7 = "extremely impaired." Patients with noninflammatory TED were further grouped into longer (>3 years) and shorter (≤3 years) disease courses. RESULTS: Patients with inflammatory (N = 307) and noninflammatory (N = 281) TED had comparable age (50.0 ± 13.3 years vs 48.3 ± 13.8 years), gender (66% men vs 64% women), TED duration (4.0 ± 4.9 years vs 4.6 ± 5.5 years), and proportion of smokers (15% vs 11%). The most common signs/symptoms of noninflammatory TED included ocular dryness/grittiness (77%), proptosis (56%), excessive tearing (43%), soft tissue edema (42%), conjunctival redness (24%) decreased vision (24%), and eye muscle involvement (22%; 14% had diplopia). All signs/symptoms were less frequently reported in these patients than in those with inflammatory TED. QoL was impacted by noninflammatory TED, although to a lesser degree than the inflammatory disease (3.6 ± 1.5 vs 4.7 ± 1.4). However, mental health issues were similarly reported. Patients with noninflammatory TED with a longer disease course (9.0 ± 6.0 years) had similar QoL impact, mental health diagnoses, and TED signs/symptoms as those with a shorter disease course (1.4 ± 1.0 years). CONCLUSION: The signs/symptoms of TED often chronically persist long after TED has "quieted," continuing to impact a patient's QoL and mental health. These data suggest that moderate-to-severe TED should be thought of as a robust symptomatic chronic disease, regardless of its inflammatory status.

RESUMEN

SIGNIFICANCE: Acquired ptosis is a condition of the upper eyelid that has negative cosmetic and functional effects but is likely underdiagnosed and undertreated. Given the evolving understanding of the condition and expanding therapeutic options, this review reappraised published evidence and clinical experience regarding diagnosis and treatment of acquired ptosis.The authors met over two structured virtual working sessions to review current evidence and develop timely recommendations for acquired ptosis identification, differential diagnosis, characterization, and treatment selection. Diagnostic algorithms, plus management and referral guidelines, are presented. Eyelid evaluation and, when needed, ptosis diagnostic workup are essential in the comprehensive eye examination. Acquired ptosis can be efficiently identified via patient questionnaire, history, and photograph review combined with assessment of eyelid position and symmetry using established methods. When ptosis is present, it is essential to evaluate onset, symptoms, pupil diameter, and extraocular muscle function to identify or rule out serious underlying conditions. If signs of serious underlying etiology are present, immediate referral/follow-up testing is required. After ruling out serious underlying causes, masquerade conditions, and pseudoptosis, pharmacologic or surgical treatment should be selected based on the clinical evidence. Effectively managing acquired ptosis requires practice-wide commitment to thorough eyelid evaluation, accurate diagnosis, and adoption of new treatment modalities. Aided by evolving pharmacologic therapeutic options, shifting from a "detect and refer" to a "diagnose and manage" approach can support identification and treatment of more patients with acquired ptosis, particularly mild-to-moderate cases.

RESUMEN

BACKGROUND: Teprotumumab, a monoclonal antibody that blocks the insulin-like growth factor-1 receptor, has recently been approved by the US Food and Drug Administration (FDA) for the treatment of thyroid eye disease (TED). Since its approval, aside from data on the safety and clinical efficacy of teprotumumab from Phase-2 and Phase-3 trials, only a handful of reports have been published regarding its use in the wider population. In this review, we briefly describe the mechanism of action of teprotumumab and review the literature to provide an overview of published clinical experience. This information was used to provide recommendations for patient selection, management of patient expectations, infusion details and site options, tips to optimize the authorization process, and how to monitor and mitigate side effects. EVIDENCE ACQUISITION: A systemic review of the literature was performed regarding teprotumumab, focusing on its mechanisms of action and published reports on its use on patients with TED. A review of Embase, Medline (PubMed), Web of Science, and Google Scholar was conducted. RESULTS: Clinical experience following the approval of teprotumumab has confirmed its efficacy in reducing inflammation and proptosis in patients with acute TED (<2 years). The reduction in proptosis occurs due to a reduction in orbital fat and muscle volume. Furthermore, there is evidence for its use in patients with compressive optic neuropathy. There are also reports that show its efficacy in reducing proptosis, inflammation, and diplopia in patients with chronic TED (>2 years). Teprotumumab was associated with side effects, such as muscle spasm, hearing loss, and hyperglycemia. To date, 2 case reports have shown a possible association with flares of inflammatory bowel disease. CONCLUSIONS: Teprotumumab is a powerful therapeutic option for the treatment of TED. Clinical experience following FDA approval has demonstrated efficacy in treating patients with acute and chronic TED. It is the only therapeutic option that has been shown to reduce orbital soft tissue expansion in TED. However, it is expensive, and sometimes, obtaining insurance authorization can be time consuming and difficult. Further work will reveal its full side effect profile and help to establish its role in the armamentarium used to treat TED.

RESUMEN

BACKGROUND: Teprotumumab is the first treatment for thyroid eye disease (TED), a debilitating autoinflammatory condition, approved by the Food and Drug Administration in the United States, which reduces proptosis and improves quality of life. In the absence of guidelines, clinical recommendations were developed for using teprotumumab in patients with TED in the United States. METHODS: A 3-round modified-Delphi panel was conducted between October 2020 and February 2021 with experts in the management of patients with TED. Key areas regarding the use of teprotumumab were investigated, including eligible patient populations, concomitant treatments, and assessment of response and adverse events. This used 2 survey rounds via an online questionnaire, where statements were scored using 9-point Likert scales. Statements with conflict were included in the third round, involving a consensus meeting via videoconference. RESULTS: Consensus was obtained for all statements (n = 75); of which, 56% were revised to enable agreement of the group. The consensus meeting provided agreement regarding which populations should receive teprotumumab therapy, including all adult patients with TED with a clinical activity score of ≥4. Treatment with teprotumumab can also be considered for TED patients displaying the following characteristics: a CAS of <3, lid retraction of ≥2, and mild or early optic neuropathy with close clinical observation. Further recommendations included suitability of treatment for those beyond 16 months following the initial diagnosis of TED, low CAS concomitant treatment with steroids in some cases, retreatment for those who have relapses, and finally a recommendation to continue therapy for all 8 infusions despite the lack of response by the fourth infusion. CONCLUSIONS: This work constitutes the first consensus on guidelines for the use of teprotumumab. The modified Delphi approach involved physicians with significant experience with the clinical use of teprotumumab, and recommendations were based on current evidence.

RESUMEN

BACKGROUND: Adenosine triphosphate (ATP) is the main energy carrier in living organisms, critical for metabolism and essential physiological processes. In humans, abnormal regulation of energy levels (ATP concentration) and power consumption (ATP consumption flux) in cells is associated with numerous diseases from cancer, to viral infection and immune dysfunction, while in microbes it influences their responses to drugs and other stresses. The measurement and modeling of ATP dynamics in cells is therefore a critical component in understanding fundamental physiology and its role in pathology. Despite the importance of ATP, our current understanding of energy dynamics and homeostasis in living cells has been limited by the lack of easy-to-use ATP sensors and the lack of models that enable accurate estimates of energy and power consumption related to these ATP dynamics. Here we describe a dynamic model and an ATP reporter that tracks ATP in E. coli over different growth phases. RESULTS: The reporter is made by fusing an ATP-sensing rrnB P1 promoter with a fast-folding and fast-degrading GFP. Good correlations between reporter GFP and cellular ATP were obtained in E. coli growing in both minimal and rich media and in various strains. The ATP reporter can reliably monitor bacterial ATP dynamics in response to nutrient availability. Fitting the dynamics of experimental data corresponding to cell growth, glucose, acetate, dissolved oxygen, and ATP yielded a mathematical and circuit model. This model can accurately predict cellular energy and power consumption under various conditions. We found that cellular power consumption varies significantly from approximately 0.8 and 0.2 million ATP/s for a tested strain during lag and stationary phases to 6.4 million ATP/s during exponential phase, indicating ~ 8-30-fold changes of metabolic rates among different growth phases. Bacteria turn over their cellular ATP pool a few times per second during the exponential phase and slow this rate by ~ 2-5-fold in lag and stationary phases. CONCLUSION: Our rrnB P1-GFP reporter and kinetic circuit model provide a fast and simple way to monitor and predict energy and power consumption dynamics in bacterial cells, which can impact fundamental scientific studies and applied medical treatments in the future.

RESUMEN

Angioleiomyomas are benign tumors composed of smooth muscle and vascular endothelium. While infrequent in overall prevalence, they are exceptionally rare in the head and neck. Herein, we describe the case of a 65-year-old female who was found to have an angioleiomyoma of the right nasolacrimal duct. Endoscopic excision of the lesion along with medial maxillectomy and dacryocystorhinostomy was performed without complication. The current report is one of the few reported cases of angioleiomyoma of the lacrimal drainage system.

RESUMEN

BACKGROUND: Thyroid eye disease (TED) is a vision-threatening and debilitating condition that until very recently had no Food and Drug Administration (FDA)-approved medical therapies. Teprotumumab has recently been approved to treat TED. We aim to provide guidance for its use, based on the input of the US investigators who participated in Phase 2 and Phase 3 clinical trials. METHODS: An expert panel was convened on October 11th and November 16th of 2019. All panel members had extensive experience as investigators in the Phase 2 and/or Phase 3 clinical trials of teprotumumab. Consensus among those investigators was reached to determine patient characteristics most appropriate for teprotumumab treatment. Safety guidelines were also reviewed and agreed on. RESULTS: The authors recommend that teprotumumab be considered first-line therapy for patients with clinically significant ophthalmopathy, including those with disease duration exceeding 9 months. The clinical activity score (CAS) may be useful for longitudinal monitoring but should not be used to determine treatment eligibility. Criteria will likely be expanded after more experience with the drug. Using teprotumumab for patients with TED with substantial signs, symptoms, or morbidity without a CAS score of >4 (e.g., progressive proptosis, diplopia, and early compressive optic neuropathy) or more, could be considered. Diabetes mellitus and inflammatory bowel disease comorbidities should not be exclusionary, but stringent monitoring in these patients is recommended. Drug dosing, administration interval, and duration should adhere to the study protocol: 8 infusions, separated by 3 weeks. Patients with more severe disease may benefit from additional doses. Corticosteroids can be used before or during teprotumumab therapy. Clinical and laboratory monitoring should be consistent with good clinical practice for patients receiving teprotumumab. CONCLUSIONS: Confirming the efficacy of teprotumumab usage outside the narrow parameters of the completed clinical trials will require rigorous scientific validation. As a step in that direction, we believe its on-label usage is appropriately applied to all patients with TED with substantial symptoms or morbidity, as judged by their physician.

RESUMEN

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.

RESUMEN

BACKGROUND: Various procedures to efface age-related lower eyelid/cheek interface depressions, or primary periorbital hollows (POHs), have been reported in the literature. Postsurgical, or secondary, POHs are a distinct contour irregularity that have received little such attention. Dermal onlay grafts (DOGs), a site-specific term for autologous dermis fat grafts, have been used to treat secondary POHs for which less invasive measures have proved unsuccessful. OBJECTIVES: The aim of this study was to describe the surgical technique and outcomes of DOGs for secondary POHs. METHODS: A retrospective analysis of patients who underwent DOGs for secondary POHs over a 27-month period was performed. The surgical technique and outcomes are reviewed. RESULTS: Thirteen patients (10 women and 3 men; average age, 52 years; average follow-up, 9 months) were included in the study. Nine patients had bilateral surgery, and all had received previous filler or fat injection, or both, with poor outcomes. Generally, surgical complications were minor, required minimal intervention, or were self-limiting. One patient had persistent infraorbital dysesthesia which improved with oral tricyclic antidepressant treatment. Eleven of 13 patients stated satisfaction with hollow effacement and outcome, a finding verified by subjective assessment by a surgeon. CONCLUSIONS: DOGs yielded good results in this initial description of their utility as a rescue procedure to surgically address secondary POHs. Further quantitative volumetric studies to validate outcome would of value.

RESUMEN

BACKGROUND: Thyroid-associated ophthalmopathy, a condition commonly associated with Graves' disease, remains inadequately treated. Current medical therapies, which primarily consist of glucocorticoids, have limited efficacy and present safety concerns. Inhibition of the insulin-like growth factor I receptor (IGF-IR) is a new therapeutic strategy to attenuate the underlying autoimmune pathogenesis of ophthalmopathy. METHODS: We conducted a multicenter, double-masked, randomized, placebo-controlled trial to determine the efficacy and safety of teprotumumab, a human monoclonal antibody inhibitor of IGF-IR, in patients with active, moderate-to-severe ophthalmopathy. A total of 88 patients were randomly assigned to receive placebo or active drug administered intravenously once every 3 weeks for a total of eight infusions. The primary end point was the response in the study eye. This response was defined as a reduction of 2 points or more in the Clinical Activity Score (scores range from 0 to 7, with a score of ≥3 indicating active thyroid-associated ophthalmopathy) and a reduction of 2 mm or more in proptosis at week 24. Secondary end points, measured as continuous variables, included proptosis, the Clinical Activity Score, and results on the Graves' ophthalmopathy-specific quality-of-life questionnaire. Adverse events were assessed. RESULTS: In the intention-to-treat population, 29 of 42 patients who received teprotumumab (69%), as compared with 9 of 45 patients who received placebo (20%), had a response at week 24 (P<0.001). Therapeutic effects were rapid; at week 6, a total of 18 of 42 patients in the teprotumumab group (43%) and 2 of 45 patients in the placebo group (4%) had a response (P<0.001). Differences between the groups increased at subsequent time points. The only drug-related adverse event was hyperglycemia in patients with diabetes; this event was controlled by adjusting medication for diabetes. CONCLUSIONS: In patients with active ophthalmopathy, teprotumumab was more effective than placebo in reducing proptosis and the Clinical Activity Score.

RESUMEN

PURPOSE: To describe a modified technique of orbicularis oculi myectomy for refractory blepharospasm. This technique includes removal of orbicularis muscle, reformation of the eyelid crease and pretarsal platform using fibrin sealant (Tisseel), and topical 5-fluorouracil to reduce scar formation and improve aesthetic outcome. METHODS: Retrospective chart review of 7 patients who underwent bilateral orbicularis oculi myectomy with our technique from 2013 to 2016. Outcome measures were postoperative botulinum toxin dose, frequency, duration between treatments, the amount of lagophthalmos, severity of dry eye, and patient satisfaction with aesthetic and functional outcome. RESULTS: Patients who underwent the aesthetic myectomy technique had significantly decreased botulinum toxin use with relief of symptoms postoperatively. Only 1 of 7 patients experienced mild dry eye symptoms postoperatively, managed with artificial tears. All patients were satisfied with the aesthetic and functional outcome. CONCLUSIONS: The aesthetic myectomy technique provides effective treatment for blepharospasm with good functional and aesthetic outcome.
