ObjectivesTo assess the efficacy and safety of adalimumab on uveitis in patients with early onset, chronic, juvenile idiopathic arthritis (JIA)-associated or idiopathic anterior uveitis and an inadequate response to topical steroids and methotrexate (MTX).MethodsPatients aged 4 years or more with ocular inflammation quantified by laser flare photometry (LFP) ≥30 photon units/ms were double-blindly randomised (1:1) to 2 groups, one treated with placebo and one with adalimumab subcutaneously at a dose of 24 mg/m2 in patients aged <13 years, 40 mg in the others, every other week. The primary outcome was response at month 2 (M2) defined as a 30% reduction of inflammation on LFP in the assessable eye with more severe baseline inflammation and no worsening on slit lamp examination. From M2 to M12, all patients received adalimumab.ResultsAt M2, among 31 patients included in intention-to-treat analysis, there were 9/16 responders on adalimumab and 3/15 on placebo (P=0.038, Χ2 test; relative risk=2.81, 95% CI 0.94 to 8.45; risk difference: 36.3%, 95% CI 2.1 to 60.6); there was no significant difference using the Standardised Uveitis Nomenclature classification criteria of improvement. Thirty patients continued the trial after M2 and received adalimumab (open-label phase), 29 reached M12. There were seven serious adverse events none related to study treatment.ConclusionsThis trial is in favour of using adalimumab in patients with early onset, chronic anterior uveitis, which is in most cases associated with JIA, in case of inadequate response to topical therapy and MTX. LFP could be a valuable tool to assess early treatment efficacy.Trial registration numberNCT01385826.

ObjectivesAcute anterior uveitis (‘uveitis’) is a common axial spondyloarthritis (axSpA) extramusculoskeletal manifestation. Interleukin (IL)-17 is implicated in its pathogenesis, however, there is conflicting evidence for IL-17A inhibition in uveitis management. We report pooled analyses of uveitis incidence in patients receiving bimekizumab (BKZ), a monoclonal IgG1 antibody that selectively inhibits IL-17F in addition to IL-17A, from phase 2b/3 trials.MethodsData were pooled for patients receiving BKZ 160 mg or placebo in the double-blind treatment period of the phase 3 BE MOBILE 1 (NCT03928704; non-radiographic axSpA) and BE MOBILE 2 (NCT03928743; radiographic axSpA) trials. Data were separately pooled for patients treated with at least one BKZ dose in the BE MOBILE trials and their ongoing open-label extension (OLE; NCT04436640), and the phase 2b BE AGILE trial (NCT02963506; radiographic axSpA) and its ongoing OLE (NCT03355573). Uveitis rates and exposure-adjusted incidence rates (EAIR)/100 patient-years (PYs) are reported.ResultsIn the BE MOBILE 1 and 2 double-blind treatment period, 0.6% (2/349) of patients receiving BKZ experienced uveitis vs 4.6% (11/237) receiving placebo (nominal p=0.001; EAIR (95% CI): 1.8/100 PYs (0.2 to 6.7) vs 15.4/100 PYs (95% CI 7.7 to 27.5)). In patients with history of uveitis, EAIR was lower in patients receiving BKZ (6.2/100 PYs (95% CI 0.2 to 34.8); 1.9%) vs placebo (70.4/100 PYs (95% CI 32.2 to 133.7); 20.0%; nominal p=0.004). In the phase 2b/3 pool (N=848; BKZ exposure: 2034.4 PYs), EAIR remained low (1.2/100 PYs (95% CI 0.8 to 1.8)).ConclusionsBimekizumab, a dual-IL-17A/F inhibitor, may confer protective effects for uveitis in patients with axSpA.

Little is known regarding anterior uveitis (AU), the most common ocular disease associated with cytomegalovirus (CMV) infection in immunocompetent populations. CMV AU is highly prevalent in Asia, with a higher incidence in men. Clinically, it manifests mainly as anterior chamber inflammation and elevated intraocular pressure (IOP). Acute CMV AU may resemble Posner–Schlossman syndrome with its recurrent hypertensive iritis, while chronic CMV AU may resemble Fuchs uveitis because of its elevated IOP. Without prompt treatment, it may progress to glaucoma; therefore, early diagnosis is critical to prognosis. Knowledge regarding clinical features and aqueous humor analyses can facilitate accurate diagnoses; so, we compared and summarized these aspects. Early antiviral treatment reduces the risk of a glaucoma surgery requirement, and therapeutic effects vary based on drug delivery. Both oral valganciclovir and topical ganciclovir can produce positive clinical outcomes, and higher concentration and frequency are beneficial in chronic CMV retinitis. An extended antiviral course could prevent relapses, but should be limited to 6 months to prevent drug resistance and side effects. In this review, we have systematically summarized the pathogenesis, clinical features, diagnostic and therapeutic aspects, and immunological mechanisms of CMV AU with the goal of providing a theoretical foundation for early clinical diagnosis and treatment.

Purpose To elucidate detailed epidemiological profile of common types of anterior uveitis (AU) in real-world clinical setting of a tertiary facility in Japan, and to evaluate the characteristic clinical findings at initial presentation. Study design Retrospective cohort study. Methods Clinical charts of 275 patients (335 eyes) aged 52.5 ± 19.1 years were reviewed retrospectively. Herpetic AU was diagnosed by multiplex polymerase chain reaction tests using aqueous humor. Time of uveitis onset, gender, laterality, disease course since the initial onset of AU, visual acuity (VA) and intraocular pressure (IOP) at first visit, and definitive diagnosis were collected from clinical charts. Results Acute AU (AAU) was the most common (21.8%) form of AU; followed by herpetic AU (20.7%) comprising Herpes Simplex Virus (HSV) (8.0%), Varicella Zoster Virus (VZV) (9.1%) and cytomegalo virus (CMV) (3.6%); scleritis (13.5%); diabetic iritis (7.6%), and Posner-Schlossman syndrome (5.5%). Unilateral AU constituted 78.2%, and VA less than 20/30 accounted for 31.2%. Of all the eyes, 16.1% had an IOP higher than 20 mmHg, out of which 37.0% had herpetic AU, followed by scleritis in 25.9%, and Posner-Schlossman syndrome (PSS) in 11.1%. AU patients over 60 years of age were 40.4%, in which 34.2% had herpetic AU, followed by scleritis in 14.4% and AAU in 13.5%. Herpetic AU patients were significantly older and had higher IOP compared with AAU patients. Conclusion The most frequent AU was AAU, followed by herpetic AU. Herpetic AU patients were older and had higher intraocular pressure than AAU patients, although VA was equally impaired in both groups.

BackgroundIt has been reported that the gut microbiome is involved in the pathogenesis of uveitis, but the specific pathogenic microbes and metabolites in different types of uveitis are still unclear.MethodsMicrobiome and metabolites were detected using 16S ribosomal DNA and LC‒MS/MS (liquid chromatography tandem mass spectrometry) in 45 individuals, including 16 patients with Vogt Koyanagi Harada (VKH), 11 patients with acute anterior uveitis (AAU) and 18 healthy controls.ResultThe diversity of intestinal microbes among the VKH, AAU and control groups was not significantly different. Thirteen specific microbes and 38 metabolites were detected in the VKH group, and 7 metabolites (vanillin, erythro-isoleucine, pyrimidine, 1-aminocyclopropanecarboxylic acid, beta-tocopherol, (-)-gallocatechin and N1-methyl-4-pyridone-3-carboxamide) significantly changed only in patients with VKH, which mainly acted on nicotinamide and nicotinamide metabolism and biotin metabolism (p<0.05). Compared with the VKH group, the AAU group had milder intestinal changes. Only 11 specific microbes and 29 metabolites changed in the AAU group, while these metabolites were not specific (p<0.05). These metabolites mainly acted on arachidonic acid metabolism. In addition, three microbes and two metabolites had the same changes in the VKH and AAU groups (p<0.05). Multiple correlations were found between gut microbes and metabolites in the VKH and AAU groups. Six microbes (Pediococcus, Pseudomonas, Rhodococcus, Photobacterium, Gardnerella and Lawsonia) and two metabolites (pyrimidine and gallocatechin) as biomarkers could effectively distinguish patients with VKH from patients with AAU and healthy individuals, with AUC (area under the curve) values greater than 82%. Four microbes (Lentilactobacillus, Lachnospiraceae_UCG-010, Cetobacterium, Liquorilactobacillus) could distinguish patients with AAU from patients with VKH and healthy controls with AUC>76%.ConclusionSignificant differences in intestinal microbes and metabolites suggest their different roles in the pathogenesis of uveitis entities. Changes in the metabolism of certain B vitamins may be involved in the pathogenesis of VKH.

Spondyloarthritis (SpA) is a group of diseases characterized by chronic inflammation and extra-articular involvement of tissues and organs. Acute anterior uveitis (AAU), the most common extra-articular manifestation of SpA, typically presents as a unilateral acute disruption of the blood-aqueous barrier, characterized by photophobia, redness of the eye, pain, and blurred vision. The underlying pathogenesis is not fully understood but is thought to involve genetic factors, gut microbiota, and dysregulation of the immune system. Corticosteroids remain the cornerstone of AAU treatment. However, alternative therapies such as nonsteroidal anti-inflammatory drugs (NSAIDs), disease modifying antirheumatic drugs (DMARDs), and biologics have also demonstrated utility. In recent years, biologics have gained increasing attention due to their efficacy and safety. This review summarizes recent research findings and advancements in the diagnosis and management of spondyloarthritis-associated uveitis.

IntroductionPaediatric patients with chronic anterior uveitis are more prone to suffer from the chronic course of intraocular inflammation and adverse effects of long-term immunomodulatory therapy, either topical glucocorticosteroids or systemic immunomodulatory agents. The performance of adalimumab has been shown to be fairly favourable in treating refractory non-infectious uveitis, but the detailed indication is still under investigation. This study aims to assess the efficacy and safety of adalimumab for inflammatory flare prevention in non-infectious paediatric anterior uveitis with peripheral retinal vascular leakage, compared with methotrexate.Methods and analysisChildren weighed ≥30 kg and aged between 4 and 16 years old with active non-infectious anterior uveitis with peripheral retinal vascular leakage on ultra-wildfield fluorescein fundus angiography will be included. They will be treated with a predesigned inflammatory control regimen to reach inflammatory quiescence in 1 month. After that they will be treated with either methotrexate 10 mg once a week or adalimumab once every 2 weeks and regularly followed up for 6 months. The primary endpoint is uveitis flare defined as defined as anterior chamber cell count grading increased from 0 to 1 within the observation period.Ethics and disseminationThe study was approved by the Institutional Review Board of Peking Union Medical College Hospital, Beijing, China (Approved protocol V3, dated 27 July 2021. Approval number 25-ZS-3062) and has been registered on ClinicalTrials.gov. Written informed consent will be collected from every patient and their guardians prior to study participation. The results of this trial will be presented at local and international meetings and submitted to peer-reviewed journals for publication.Trial registration numberNCT05015335.

To compare femtosecond laser-assisted cataract surgery with standard phacoemulsification concerning the incidence of postoperative clinical or subclinical macular edema and the correlation between macular thickness and postoperative intraocular inflammation values. One hundred four eyes of 104 patients were treated by laser-assisted cataract surgery and the fellow 104 eyes underwent phacoemulsification using pulsed ultrasound energy and intraocular lens implantation in this prospective randomized study. Laser flare photometry was measured preoperatively and at 2 hours, 3 to 4 days, 1 month, 3 months, and 6 months postoperatively. Retinal thickness was measured by spectral-domain optical coherence tomography. Two hundred two eyes (97%) were included and analyzed at 6 months postoperatively. The mean center thickness in the laser group was 210 ± 24 μm at 4 days postoperatively, 214 ± 22 μm at 1 month postoperatively, 219 ± 20 μm at 3 months postoperatively, and 215 ± 22 μm at 6 months postoperatively. The mean center thickness in the standard group was 211 ± 32 μm at 4 days postoperatively, 210 ± 34 μm at 1 month postoperatively, 217 ± 29 μm at 3 months postoperatively, and 209 ± 30 μm at 6 months postoperatively. Laser flare photometry showed higher levels in the standard group at the first postoperative visit 2 hours after surgery compared with the laser group. Femtosecond laser-assisted cataract surgery did not obviously influence the incidence of postoperative macular edema.

Background To analyze whether ANA-positive idiopathic anterior uveitis differs from JIA-associated uveitis concerning clinical course, response to treatment, and disease outcome. Methods Prospective study of the National Paediatric Rheumatological Database (NPRD) including its uveitis add-on module from the years 2002 to 2016. Cross-sectional data from the years 2002 to 2016 were analyzed. Patients with JIA-associated uveitis and with ANA-positive idiopathic anterior uveitis were included and the disease manifestation investigated in terms of uveitis characteristics and disease course. Results Of the total cohort of 34,458 patients enrolled in the NPRD, including 3551 patients with uveitis, those with detailed uveitis documentation were taken into account: 62 ANA-positive patients with idiopathic anterior uveitis (group 1), 688 patients with initial uveitis diagnosis after JIA onset (group 2), and 61 JIA patients with initial uveitis diagnosis before arthritis onset (group 3). Anterior uveitis was documented in 100%, 94%, and 80% of patients and with insidious onset of uveitis flare in 50%, 70.9%, and 56.1% each in groups 1, 2, and 3, respectively. Use of topical or systemic corticosteroids and conventional synthetic or biological DMARDs did not significantly differ between the patient groups, either at the initial or the 2-year follow-up (2-FU) visits (mean 2 years, each p  > 0.05). At 2-FU, uveitis inactivity was achieved in 64.7%, 55.8%, and 61.5% of patients in groups 1, 2, and 3 ( p  > 0.05). Uveitis-related complications were more frequent at the initial visit and at 2-FU in groups 1 and 3, as compared to group 2. Conclusions ANA-positive idiopathic uveitis and JIA-associated uveitis do not significantly differ concerning clinical course of uveitis, treatment, and response to corticosteroids and DMARDs.

Summary This prospective study showed that the incidence of acute anterior uveitis, confirmed by ophthalmic examination, in patients receiving intravenous zoledronate infusions as part of a randomized controlled trial for fracture prevention is 1.1 %. Introduction We prospectively investigated the incidence of ocular side effects after a single intravenous zoledronate infusion. Methods In a secondary analysis of a double-blind, placebo-controlled trial in which early post-menopausal women ( N  = 1054) with normal bone density or osteopenia were randomized to infusion of zoledronate 5 mg ( N  = 703) or placebo ( N  = 351), we analyzed significant adverse ocular events occurring within 3 months. Results Fourteen participants reported ocular symptoms after the infusion. All were examined by an ophthalmologist and eight were diagnosed with acute anterior uveitis (AAU) and one with sectoral episcleritis. The incidence of AAU and episcleritis was 1.1 % (95 % CI 0.5–2.1) and 0.1 % (95 % CI 0.0–0.7), respectively, in the zoledronate group and 0 % for both conditions in the placebo group (95 % CI 0.0–0.8). The mean time from infusion to symptom onset for AAU was 3 days (range 2–4). Three cases were bilateral. AAU was mild-moderate in seven participants and severe in one. All affected eyes were treated with topical cyclopentolate 1 % (to break, or minimize, posterior synechiae), and intensive, potent, topical corticosteroids with a tapering regime based on treatment response. The mean duration of topical corticosteroid was 26 ± 10 days (range 17–44). The mean, best corrected visual acuity was 20/20 (range 20/20–20/40) at presentation, which remained unchanged after AAU resolution. None of the participants lost vision, and no long-term sequelae were reported at last follow-up (range 3–13 months post-infusion). Conclusions Prescribers should inform patients about the possibility of ocular side effects with zoledronate infusions and refer promptly to an ophthalmologist if symptoms develop.
