Childhood-Onset Non-Infectious Uveitis in the "Biologic Era". Results From Spanish Multicenter Multidisciplinary Real-World Clinical Settings.

OBJECTIVE: To characterize and describe clinical experience with childhood-onset non-infectious uveitis. STUDY DESIGN: A multicenter retrospective multidisciplinary national web-based registry of 507 patients from 21 hospitals was analyzed. Cases were grouped as immune disease-associated (IMDu), idiopathic (IDIu) or ophthalmologically distinct. Characteristics of juvenile idiopathic arthritis-associated (non-HLA-B27-related) uveitis (JIAu), IDIu, and pars planitis (PP) were compared. RESULTS: IMDu (62.3%) and JIAu (51.9%) predominated in young females; and IDIu (22.7%) and PP (13.6%) in older children, without sex imbalance. Ocular complications occurred in 45.3% of cases (posterior synechiae [28%], cataracts [16%], band keratopathy [14%], ocular hypertension [11%] and cystoid macular edema [10%]) and were associated with synthetic (86%) and biologic (65%) disease-modifying antirheumatic drug (DMARD) use. Subgroups were significantly associated (p < 0.05) with different characteristics. JIAu was typically anterior (98%), insidious (75%), in ANA-positive (69%), young females (82%) with fewer complications (31%), better visual outcomes, and later use of uveitis-effective biologics. In contrast, IDIu was characteristically anterior (87%) or panuveitic (12.1%), with acute onset (60%) and more complications at onset (59%: synechiae [31%] and cataracts [9.6%]) and less DMARD use, while PP is intermediate, and was mostly bilateral (72.5%), persistent (86.5%) and chronic (86.8%), with more complications (70%; mainly posterior segment and cataracts at last visit), impaired visual acuity at onset, and greater systemic (81.2%), subtenon (29.1%) and intravitreal (10.1%) steroid use. CONCLUSION: Prognosis of childhood uveitis has improved in the "biologic era," particularly in JIAu. Early referral and DMARD therapy may reduce steroid use and improve outcomes, especially in PP and IDIu.

Successful tocilizumab treatment in a child with refractory Takayasu arteritis.

Takayasu arteritis (TA) in the child remains a therapeutic challenge because corticosteroids and conventional immunosuppressive agents are not always safe or efficacious. The complex formed by interleukin-6 (IL-6) and soluble IL-6 receptor appears to play a pivotal role in the pathogenesis of TA. We describe a favorable response to the anti-IL-6 receptor antibody tocilizumab (TCZ) in a child with aggressive and refractory TA including an assessment of the proinflammatory cytokine profile. A 3-year-old girl with TA consisting of thickening of the aortic arch wall, severe obstruction of the supra-aortic branches, and complete occlusion of both common carotid arteries failed to respond to corticosteroids, methotrexate, tumor necrosis factor α blockade, cyclophosphamide, and mycophenolate mofetil, and 3 years later, the disease remained active with severe manifestations (brain ischemia). The patient underwent percutaneous angioplasty, although significant restenosis was soon documented. After a severe relapse, the patient started TCZ infusions (8 mg/kg for 2 weeks), and a rapid clinical remission was observed, associated with a drastic reduction of inflammatory markers and IL-6 levels. Corticosteroids were withdrawn, the patient's weight and height improved, and bone mineral density values returned to normal. Two years later, TCZ infusions were extended, with no significant side effects. Cerebral ischemia resolved, and recanalization of the previously occluded supra-aortic branches was performed.
