Steroid-Resistant Graves' Orbitopathy Treated with Tocilizumab in Real-World Clinical Practice: A 9-Year Single-Center Experience.

ABSTRACT: This study aimed to assess the effectiveness and safety of tocilizumab use for the treatment of active steroid-resistant Graves' orbitopathy (GO). A retrospective longitudinal study was conducted by reviewing the medical records at a single center between November 2009 and December 2018. A total of 114 patients with steroid-resistant Graves' orbitopathy were examined and treated with tocilizumab, of which 54 adults met the inclusion criteria. No concomitant medication for the treatment of orbitopathy was used. The main primary outcomes included changes from baseline in the Clinical Activity Score (CAS) and thyrotropin receptor antibody (TRAb) levels throughout therapy with tocilizumab. The absolute responses to treatment were defined as the achievement of CAS ? 1 and TRAb ? 10 U/L. A composite ophthalmic score including CAS, proptosis, eyelid retraction, and diplopia was used to evaluate individual improvement in GO. Adverse drug reactions were also assessed. Analysis of the patient's CAS and TRAb levels showed meaningful reductions during tocilizumab treatment. Differences between values at baseline and subsequent time points were statistically significant (p < 0.001 for all comparisons). The absolute CAS response (CAS = 0 or 1) was achieved in 74% (37/50) of patients after the fourth dose of tocilizumab (at week 16), with a TRAb response being achieved in 55% (23/42) of patients. The relative CAS response (reduction ? 2 points) was achieved in 90.9% of patients (40/44) after the first dose of tocilizumab (at week 4). Measurements of proptosis (reduction ? 2 mm in 78% of patients, 42/54) and eyelid retraction (reduction ? 2 mm in 75%, 33/44), and the prevalence of diplopia (improvement in 68%, 19/28) were significantly reduced after the last dose of tocilizumab (p < 0.001 for all comparisons). GO improved in 98% (53/54) of patients when at least two criteria of the composite evaluation were required. Four patients exhibited disease recurrence, defined as an increase in CAS of ?2 points in the six months following the date of inactivation. Most adverse drug reactions were mild or moderate in severity. In conclusion, our data suggest that a course of at least 4 months (one monthly dose) of tocilizumab therapy provides a significant benefit to patients with active moderate-to-severe steroid-resistant GO.

Project description:BackgroundPlacebo-controlled clinical trials have demonstrated the efficacy of tocilizumab (TCZ) for remission maintenance and glucocorticoid sparing in patients with giant cell arteritis (GCA). However, limited data exist on the effectiveness and safety of TCZ for GCA in real-world clinical practice.MethodsThis was a retrospective, single-center analysis of patients with GCA treated with intravenous or subcutaneous TCZ (2010-2018). Outcomes evaluated before and after TCZ initiation included occurrence of flare, time to flare, annualized flare rate, flare characteristics (i.e., polymyalgia rheumatica [PMR] symptoms, cranial manifestations), prednisone use, and safety. Flare was defined as the recurrence of unequivocal GCA manifestations requiring treatment intensification. Subgroup analyses of patients with PMR or visual manifestations at GCA diagnosis were performed.ResultsSixty patients with GCA were included. The median (IQR) disease duration before and after the start of TCZ was 0.6 (0.2-1.6) and 0.5 (0.3-1.4) years, respectively. At least 1 flare was observed in 43 patients (71.7%) before and in 18 (30.0%) after TCZ initiation. Median (IQR) time to flare was 0.5 (0.3-0.7) years before TCZ treatment and 2.1 (0.6-2.6) years after TCZ initiation (HR 0.22; 95% CI 0.10-0.50; p = 0.0003). The annualized flare rate significantly decreased following TCZ use (before TCZ 1.4 [95% CI 1.0-2.1]; after TCZ 0.6 [95% CI 0.3-1.0] events/year; p < 0.001). Similar improvements were observed in patients with visual manifestations or PMR symptoms at GCA diagnosis. TCZ reduced the incidence of new visual manifestations, and no flares associated with permanent vision loss occurred while patients were receiving TCZ. Mean (SD) prednisone dose at TCZ onset and at the end of follow-up was 30 (18.3) and 5 (6.9) mg/day, respectively (p < 0.0001). After TCZ initiation, 46.6% of patients successfully discontinued prednisone. The incidence of adverse events, primarily attributed to glucocorticoids, was similar before and after TCZ initiation.ConclusionsIn this real-world setting, TCZ improved GCA clinical outcomes significantly and demonstrated effectiveness in the subgroups of patients with PMR symptoms and GCA-related visual manifestations at GCA diagnosis. No new cases of blindness occurred after TCZ initiation. Adverse events, many attributable to glucocorticoids, were comparable before and after TCZ treatment.

Project description:Purpose Severity of Graves’ orbitopathy (GO) shows wide individual differences. For optimal treatment, it is important to be able to predict the natural course of the disease as accurate as possible to counteract with anti-inflammatory and surgical treatment. Therefore, we aimed to further elucidate the impact of sex, age and smoking on GO. Methods We collected the clinical and demographic data of all patients of our tertiary referral center from January 2008 till December 2018 and analyzed it with descriptive statistics. Only patients with a complete data set were included in the further analysis. Odds ratio’s for moderate-to-severe and sight-threatening GO in relation to age, sex and smoking were calculated by means of multivariate logistic regression models. Results We evaluated the data of 4260 patient with GO and complete data sets. Most of these were women (83%). There were no significant differences between male and female patients regarding smoking habits and thyroid treatment. Men were significantly older at initial manifestation of TED (51.8 vs. 49.9y, p<0.01) and showed significant more often severe stages (61% vs. 53%, p<0.0001). Therefore, they needed significantly more intense treatment with steroids, irradiation, orbital decompression and muscle surgery. In multivariate logistic regression analyses age (OR 0.97, 95% CI:0.97-0.98, p<0.0001), male sex (OR 1.64, 95% CI:1.38-1.9, p<0.0001), smoking (OR 1.19, 95% CI:1.04-1.36, p=0.01), Grave’s disease (OR 1.55, 95% CI:1.26-1.90, p<0.0001) and history of radioiodine treatment (RAI) (OR 2.44, 95% CI:2.10-2.86, p<0.0001) showed an significant association with severe stages of GO. Discussion Our retrospective analysis showed once more that women are more often afflicted by GO. In contrast, men seem to be more severely afflicted and in need of anti-inflammatory and surgical treatments. This might be due to a different approach to the health system and resilience to GO specific symptoms, as well as previously described worse thyroid control. Estrogen mediated effects might also play a role as in other autoimmune diseases and should be subject of further trials. Besides the biological sex, smoking could again be confirmed as serious risk factor for severe GO. Of note, RAI was associated with more severe stages of GO, which should be subject to further investigation.
