Posterior segment inflammatory outcomes assessed using fluorescein angiography in the STOP-UVEITIS study.

ABSTRACT: Background:Although fluorescein angiography (FA) is a frequently used imaging modality in patients with non-infectious uveitis (NIU), it has not been reliably used for objective assessment of posterior segment inflammatory outcomes in these patients. In this index study we report the posterior segment inflammatory outcomes of two different doses of intravenous (IV) infusions of tocilizumab (TCZ), an IL-6 inhibitor, in eyes with NIU using a semi-quantitative FA scoring system. Methods:STOP-Uveitis is a randomized, multi-center clinical trial conducted at 5 clinical centers across the United States. The study evaluated the role of TCZ in patients with NIU. Thirty-seven (37) patients with NIU were randomized into one of two treatment groups in a ratio of 1:1. Group 1 received IV infusions of 4 mg/kg TCZ and group 2 received IV infusions of 8 mg/kg TCZ. Infusions were given every 4 weeks in both groups until month 6 (primary endpoint). Posterior segment inflammatory outcomes were assessed by evaluating FA at baseline and month 6 by graders at a central reading center. A previously reported, semi-quantitative, scoring system for FA was used to assess signs that represent ongoing inflammatory processes in the posterior segment. These signs included optic disc hyperfluorescence, macular edema, retinal vascular staining and/or leakage, capillary leakage, retinal capillary nonperfusion, neovascularization of the optic disc, neovascularization elsewhere, pinpoint leaks, and retinal staining and/or subretinal pooling. Statistical significance was set at p?

Project description:PurposeTo evaluate the role of vitreomacular adhesion (VMA) in visual and anatomic outcomes in patients with non-infectious uveitis.DesignPhase 2 clinical trial PARTICIPANTS: Data from the Safety, Tolerability, and Efficacy of Tocilizumab in Patients with Non-infectious Uveitis (STOP-Uveitis) study was analyzed.MethodsIn the STOP-Uveitis study, patients with non-infectious uveitis (NIU) received monthly intravenous infusions of either 4 or 8 mg/kg tocilizumab until month 6 (M6). Spectral domain optical coherence tomography (SD-OCT) images of patients that completed M6 of the study were analyzed at baseline to stratify the patients by the presence (VMA+) or absence (VMA-) of VMA. Patients with vitreomacular traction (VMT) or epiretinal membrane causing structural abnormalities within center 1 mm were excluded. All images were graded by two independent graders.Main outcome measuresMean change in best-corrected visual acuity (BCVA), central retinal thickness (CRT), and vitreous haze (VH) at M6.ResultsOut of 37 patients randomized in the STOP-Uveitis study, 48 eyes (27 patients) were eligible based on the study criteria. At baseline, 19 eyes were classified as VMA+, and 32 eyes were classified as VMA-. The distribution of two doses of TCZ (4 mg/kg and 8 mg/kg) were similar between the two groups. At M6, the mean improvement in BCVA was 2.00 ± 5.3 and 6.50 ± 7.98 letters in the VMA+ and VMA- groups, respectively (p = 0.02). The mean improvement in CRT was 34.85 ± 72.36 and 80.37 ± 157.21 μm in the VMA+ and VMA- groups, respectively (p = 0.18). Similarly, the mean change in VH was - 0.65 ± 0.47 and - 0.76 ± 0.71 in the VMA+ and VMA- groups, respectively (p = 0.32). Out of 16 eyes with VMA at baseline, 3 eyes developed posterior vitreous detachment (PVD) at M6. The mean change in BCVA was significantly higher (p = 0.02), while CRT and VH score were similar (p > 0.05) in eyes with PVD compared to eyes with persistent VMA.ConclusionsThe absence of VMA or development of PVD in eyes with VMA seems to have a beneficial effect on the vision of subjects receiving treatment for uveitis. Therefore, patients with uveitis should be assessed using SD-OCT for the presence of vitreomacular interface abnormalities.
