Background Refractory non-infectious uveitis is a serious condition that leads to ocular complications and vision loss and requires effective systemic treatment to control disease. The effectiveness ...of long-term infliximab IFX in refractory non-infectious childhood uveitis and the impact of treatment adherence on disease control were evaluated. Methods Retrospective, single-center study between December 2002 and April 2016 of 27 children with refractory non-infectious uveitis 17 with juvenile idiopathic arthritis, JIA treated with long-term IFX 9+ months. Disease activity was assessed prior to and while on IFX using the Standardization of Uveitis Nomenclature SUN. Number of visits per year with active uveitis was analyzed by repeated measures logistic regression analysis from 2 years prior to IFX initiation or from onset of uveitis until most recent visit on IFX. Incomplete treatment adherence was assessed for each visit and defined as any deviance in corticosteroid use, prescribed infusion frequency, and/or follow-up examination frequency. Results Primary outcomes were sustained uveitic and systemic disease control prior to and during IFX treatment and the impact of incomplete adherence on uveitic disease control while on IFX. Secondary outcomes included corticosteroid and glaucoma medication requirement, ocular complications and need for surgical intervention. Mean age at IFX initiation was 10.4 + or - 4.5 years; initial mean dose was 6.6 + or - 2.2 mg/kg and given at weeks 0, 2, 4 and q4 weeks thereafter for 93%. Median duration on IFX was 35 range 9-128 months. Prior to IFX, 14/27 patients had failed adalimumab + or - methotrexate MTX; 21/27 failed MTX. IFX led to uveitis control in 89% and arthritis control in 76% (13/17). The odds ratio of having controlled disease after IFX was 4.1 (2.6, 6.4) compared to pre-treatment visits. Topical corticosteroids and glaucoma medications were statistically decreased (p = 0.007 right eye OD, 0.003 left eye OS and p = 0.001 OD, p = 0.028 OS respectively). Incomplete adherence to treatment showed 10.3 times greater odds (7.1, 15.0) of having disease activity than full adherence. Conclusions This study adds significantly to the IFX literature by documenting outstanding uveitis control with long-term IFX treatment in non-infectious pediatric uveitis patients. Higher dosage and shorter interval were utilized without adverse effects. Importantly, this is the first study, to our knowledge, to document the significant impact of treatment adherence on uveitis control.

•Uncontrolled, chronic anterior uveitis leads to ocular morbidity in children.•Failed treatment with methotrexate and adalimumab and/or infliximab is not uncommon.•Alternative biologic agents include ...golimumab, tocilizumab, and abatacept.•Nine patients with resistant disease were successfully treated with alternative biologic agents.
A significant number of children with noninfectious, chronic anterior uveitis (CAU) fail to respond to conventional therapy; however, successful alternative biologic treatments (ABT) have not been well described. This study aims to review the clinical and treatment characteristics of children with CAU who require ABT.
Retrospective, nonrandomized clinical study.
Setting: Tertiary center. Study Population: Children with noninfectious CAU. Observation Procedures: Clinical characteristics, uveitis course, complications, and treatment were compared among patients treated with methotrexate (MTX) monotherapy, conventional TNFα inhibitors (cTNFi), and ABT for >3 months. Main Outcome Measure: Success of ABT (abatacept, tocilizumab, and/or golimumab) in children failing conventional treatment.
Of the 52 children with CAU, 75% had juvenile idiopathic arthritis. CAU was controlled in 15 children receiving MTX monotherapy, 28 receiving cTNFi, and 9 receiving ABT (n = 1, abatacept; n = 3, tocilizumab; n = 5, golimumab). Patients in the ABT group had a greater number of total ocular complications per person before ABT than those in the control groups (3.4 vs 0.7 MTX, P < .001, and 1.5 cTNFi, P < .001, respectively). In all 9 children on ABT, treatment led to control of CAU and topical glucocorticoids tapered to ≤2 drops/d with no new ocular complications.
In this study, alternative biologics (abatacept, golimumab, and tocilizumab) were useful for treating CAU in children who fail MTX and cTNFi therapy. Patients who were controlled on ABT had more disease activity, ocular complications, and anti-cTNFi neutralizing antibodies (before ABT) than those managed with conventional therapy. Larger studies are required to confirm these findings.
