Epidemiology, Treatment, and Outcomes of Juvenile Idiopathic Arthritis-Associated Uveitis: A Multi-Institutional Study in Taiwan

Effectiveness and Safety of Weekly Adalimumab for Non-Infectious Chronic Anterior Uveitis in Children

PURPOSE

Non-infectious chronic anterior uveitis (CAU) remains a therapeutic challenge. The purpose of this study was to analyze the effectiveness and safety of weekly dosing of adalimumab in children with non-infectious refractory CAU. Methods: Demographic and clinical data of children followed by non-infectious CAU treated with adalimumab were retrospectively reviewed.

RESULTS

Of the 42 children with CAU, 27/42 (64.3%) were treated with adalimumab. Escalation to weekly dosing of adalimumab was necessary for 11/27 children (40.7%). After 3 and 6 months, 7/11 children (63.6%) met the composite endpoint of inflammation control improvement. Children requiring weekly adalimumab had initially more severe uveitis: anterior chamber cells (p = 0.02), aqueous flare (p = 0.02), and presence of macular edema (p = 0.007). No children had serious systemic side effects.

CONCLUSION

Weekly adalimumab in children with refractory CAU appears to be an effective and safe treatment for inflammation control and corticosteroid sparing, and an alternative before biologic switching. Controlled studies are needed.

Encouraging visual outcomes in children with idiopathic and JIA associated uveitis: a population-based study

BACKGROUND

Pediatric uveitis is typically asymptomatic and may become chronic affecting ocular structures and vision. We evaluated visual outcomes, clinical features, medication, and uveitis activity in children with either idiopathic uveitis (idio-U) or juvenile idiopathic arthritis associated uveitis (JIA-U).

METHODS

A longitudinal, population-based cohort study of children with uveitis in 2008-2017. The data included parameters for age, gender, age at diagnosis, laterality, chronicity, anatomical distribution, etiology, systemic association, uveitis activity, medication, and visual outcomes.

RESULTS

A total of 119 patients aged < 16 years with uveitis were included. Uveitis was idio-U in 23% and associated with JIA in 77% of cases. 37% of the patients in the idio-U group and 65% in the JIA-U were girls (p = 0.014). The mean age at first uveitis was 10.0 (SD 3.4) years in idio-U and 5.5 (SD 3.3) years in JIA-U (p < 0.001). Anterior location of uveitis was noted in 74% in idio-U and 99% in JIA-U (p < 0.001). Mostly, uveitis was chronic (59% in idio-U and 75% in JIA-U) and bilateral (56% in idio-U and 64% in JIA-U). Topical corticosteroids were initially used by 89% and 100%, systemic corticosteroids by 30% and 27% in some extent during the follow-up, disease-modifying antirheumatic drugs (DMARDs) by 33% and 85% (p < 0.001) of the patients in idio-U and JIA-U, respectively. Biologic disease-modifying antirheumatic drugs (bDMARDs) were more common in JIA-U (55% vs. 15% in idio-U, respectively, p < 0.001). Most patients had normal visual acuity (Snellen > 0.8, [6/7.5]) in the affected eye and bilaterally in 85% idio-U and 70% JIA-U. Only 5 patients (4%) had visual impairment in one, but none in both eyes. Uveitis activity by SUN classification was 0 + in 81% and 72%, 0.5 + in 19% and 25%, and 1 + in 0% and 3% in the idio-U and JIA-U, respectively.

CONCLUSIONS

Children with uveitis have good visual acuity and a low rate for visual impairment. In addition, modern treatment with DMARDs and bDMARDs seems to save vision.
