A randomized non-inferiority trial of therapeutic strategy with immunosuppressants versus biologics for Vogt-Koyanagi-Harada disease.

ABSTRACT: Biologics are increasingly used to treat Vogt-Koyanagi-Harada disease, but head-to-head comparisons with conventional immunosuppressants are lacking. Here in this randomized trial (Chinese Clinical Trial Registry, ChiCTR2100043061), we assigned 110 patients (27 early-phase and 83 late-phase) to cyclosporine-based immunosuppressant strategy (N = 56) or adalimumab-based biologic strategy (N = 54), each combined with a modified corticosteroid regimen. The primary outcome is change from baseline in best-corrected visual acuity at week 26. The margin of non-inferiority for cyclosporine is -7 letters. The primary outcome is 11.2 letters (95% CI, 7.5 to 14.9) in the cyclosporine group and 6.3 letters (95% CI, 3.1 to 9.6) in the adalimumab group (difference, 4.9; 95% CI, 0.2 to 9.5; P < 0.001 for non-inferiority). The between-group difference is -0.8 letters (95% CI, -6.1 to 4.5) in early-phase disease and 5.7 letters (95% CI, 0.2 to 11.2) in late-phase. Serious adverse events are reported less frequently in the cyclosporine group than in the adalimumab group (0.70 vs. 1.21 events per patient-year). Here, we report that combined with a non-standard corticosteroid regimen, cyclosporine-based immunosuppressant strategy is non-inferior to adalimumab-based biologic strategy by 26 weeks for visual improvement in a cohort of patients with Vogt-Koyanagi-Harada disease, 75% of whom have a late-phase disease.

Project description:BackgroundHigh dose systemic glucocorticoid is the main therapy of treatment-naïve Vogt-Koyanagi-Harada (VKH) disease. However, series side effects induced by high dose systemic glucocorticoid frequently occur, which makes alternative therapy necessary for certain patients. This study sought to compare the efficacy and safety of systemic glucocorticoid-free (SGF) therapy with conventional therapy (CT) as an initial treatment for VKH patients.MethodsVKH patients who had not been systemically treated were enrolled. Patients were allocated into 2 therapeutic groups depending on their treatments. In CT group, patients received systemic glucocorticoid plus immunosuppressants (IS), and in SGF group, patients received adalimumab (ADA) plus IS. Patients received approximately 12 months treatment and visit monthly. The outcome parameters included the changes of best-corrected visual acuity (BCVA), intraocular inflammation (including anterior chamber cell grade and vitritis grade) and central macular thickness (CMT) (the change values define as the final-visit values subtracted from baseline counterparts). Other outcomes included the relapses times of ocular inflammation, adverse events (AEs), changes of optic nerve inflammation (ONI) and intraocular/extraocular manifestations.ResultsA total of 30 patients (60 eyes) were included. with 19 patients (38 eyes) in CT group and 11 patients (22 eyes) in SGF group. After approximately 1 year of treatment, the improvements of BCVA were slight better in the SGF group (0.57±0.23) than in the CT group (0.40±0.26), (P=0.014). In both groups, the ocular inflammatory improvements in both groups were similar, with an improvement of AC cell grade of -1.5 (-2, -0.5) in CT group versus -1 (-2, -1) in SGF group (P=0.367); improvement of vitritis grade was 0 (-1.25, 0) in CT group and -1 (-1, -1) in SGF group (P=0.050). The improvement in CMT was similar in both groups, with -523.47±412.09 µm in CT group and -362.73±375.73 µm in SGF group (P=0.572). The mean number of relapses was 1 (0, 2) in the CT group and 0 (0, 2) in the SGF group (P=0.372). No severe AEs were observed in this study.ConclusionsSGF therapy is effective, safe, and well-tolerated in treatment-naïve VKH patients. SGF therapy seems to be a feasible option in patients with existing systemic diseases intolerant to glucocorticoid.

Project description:PurposeAs an autoimmune disease, Vogt‒Koyanagi‒Harada disease (VKHD) is a main type of uveitis in many countries and regions, significantly impacting patient vision. At present, information regarding VKHD is still limited, and further research is needed. We conducted a bibliometric analysis to characterize the overall status, current trends, and current focus of VKHD research.MethodLiterature published from 1975 to 2022 was obtained from the Web of Science core collection and analysed with the R-language packages Bibliometrix, VOSviewer, and CiteSpace software.ResultsA total of 1050 papers on VKHD were retrieved from 261 journals, and 16,084 references were obtained from the papers in the original search. The average annual number of published articles was approximately 21.9, and the number of publications rapidly increased after 2004. The journal Ocular Immunology and Inflammation published the most papers on VKHD, while the American Journal of Ophthalmology has the highest citation frequency. The leading countries were Japan, China (PRC), and the United States of America (USA). Yang PZ from Chongqing Medical University was the most prolific and cited author. The most frequently cited study discussed revision of VKHD diagnostic criteria. An analysis of the highest frequency keywords showed that most research focused on the treatment, diagnosis, and pathogenesis of VKHD and its relationship with other related diseases. At present, the most urgent research direction is in the relationship between COVID-19 or COVID-19 vaccines and VKHD and the corresponding mechanisms underlying it.ConclusionUtilizing dynamic and visualization tools, bibliometrics provides a clear depiction of the research history, development trends, and research hotspots in VKHD It serves as a valuable tool for identifying research gaps and areas that necessitate further exploration. Our study revealed potential directions for future VKHD research, including investigating specific molecular mechanisms underlying the disease, exploring the clinical utility of optical coherence tomography angiography and other diagnostic techniques, and conducting clinical research on novel therapeutic drugs.

Project description:ImportanceTo our knowledge, a set of well-defined diagnostic criteria is not yet developed for the diagnosis of Vogt-Koyanagi-Harada (VKH) disease.ObjectiveTo develop and evaluate a set of diagnostic criteria for VKH disease using data from Chinese patients.Design, setting, and participantsThis case-control study reviewed medical records of patients from a tertiary referral center between October 2011 and October 2016. Data from 634 patients with VKH disease and 623 patients with non-VKH uveitis from southern China were used to develop the Diagnostic Criteria for VKH Disease (DCV). Data from an additional group of 537 patients with a definite VKH disease diagnosis and 525 patients with non-VKH uveitis from northern China were used to evaluate the diagnostic criteria.Main outcomes and measuresSensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and receiver operating characteristic.ResultsOf the 1257 patients used to construct the DCV, 665 (52.9%) were male, and the mean (SD) age at disease onset was 38.6 (13.6) years. The 3-class model and 21 clinical findings were selected by latent class analysis. Variables with a high positive rate in the early-phase or late-phase VKH group or high specificity constituted essential parameters. Constellations of these essential parameters constructed the DCV. The sensitivity and NPV of the DCV were higher than those of the Revised Diagnostic Criteria for VKH Disease (RDC) (sensitivity: 94.6% vs 71.9%; difference, 22.7%; 95% CI, 18.5-27.0; NPV: 94.3% vs 76.6%; difference, 17.7%; 95% CI, 13.9-21.5). The specificity and PPV of the DCV were not different from that of the RDC (specificity: 92.2% vs 93.9%; difference, 1.7%; 95% CI, -1.4 to 4.8; PPV: 89.3% vs 92.3%; difference, 3.0%; 95% CI, -1.4 to 4.8). The area under the receiver operating characteristic curve of the DCV and the RDC were 0.934 (95% CI, 0.917-0.951) and 0.829 (95% CI, 0.803-0.855), respectively.Conclusions and relevanceThe DCV were developed and evaluated using data from Chinese patients with VKH disease and showed a high sensitivity, NPV, and area under the receiver operating characteristic curve in comparison with the RDC. However, they were developed using a retrospective analysis and should be evaluated in prospective studies in other racial/ethnic populations.
