Pediatric Non-Infectious Uveitis: Long-Term Outcomes and Complications

Noninfectious Uveitis in Pediatric Rheumatology: Long-term Follow-up at Tertiary Centers

OBJECTIVES

Our study aimed to identify potential predictors for additional systemic involvement in patients with noninfectious uveitis, specifically focusing on their demographic, etiological, clinical, and laboratory data features from the pediatric rheumatology perspective.

METHODS

Patients with noninfectious uveitis before the age of 18 years and followed up for at least 3 months in 2 tertiary centers of pediatric rheumatology and ophthalmology departments were included in the study. Demographics, etiology, clinical features, laboratory data, and treatments administered were evaluated and compared based on the etiology (idiopathic and systemic disease-related uveitis [SD-U]) and the use of biologic disease-modifying antirheumatic drugs.

RESULTS

Of 244 patients (131 with idiopathic uveitis and 113 with SD-U), 141 (57.8%) were female. The median (min-max) age at uveitis diagnosis was 8 (1-17) years, with a median (min-max) follow-up period of 36 (3-216) months. We observed that uveitis was mostly anterior (n = 140, 57.4%), chronic (n = 122, 67.4%), and bilateral (n = 146, 59.8%). Patients with SD-U showed a higher prevalence of female predominance, younger age at diagnosis, bilateral involvement, chronic course, increased erythrocyte sedimentation rate value, and antinuclear antibody positivity compared with patients with idiopathic uveitis (p < 0.05). Uveitis-related complications occurred in 105 (43%) patients, with the most common being posterior synechiae (n = 60, 24.6%). Ocular surgery was required for 7 patients (5.3%) in idiopathic uveitis and for 14 patients (12.4%) in SD-U group.

CONCLUSION

Our study demonstrated that the antinuclear antibody positivity and the high erythrocyte sedimentation rate values were identified as significant, independent predictors for SD-U in patients referred with noninfectious uveitis.

The Efficacy of Adalimumab Treatment in Pediatric Non-Infectious Uveitis: A Retrospective Cohort Study

Objectives

To evaluate the clinical features of pediatric non-infectious uveitis (NIU) patients treated with adalimumab (ADA) and the efficacy of ADA in patients unresponsive to conventional immunosuppressive therapy.

Materials and Methods

The records of 91 NIU patients aged ≤16 years who received ADA therapy were evaluated retrospectively. The patients' demographic and clinical characteristics and treatment approaches were recorded. The efficacy of ADA in patients treated for at least 1 year after failure of conventional immunosuppressive treatment was evaluated by comparing the best corrected visual acuity (BCVA), severity of intraocular inflammation, uveitis flare-ups, topical and systemic corticosteroid (CS) use, and central macular thickness (CMT) values before and after ADA treatment.

Results

The study included 103 eyes of 53 patients, of whom 29 (54.7%) were female. The mean age at presentation was 8.2±3.4 (range: 3-16) years. The mean follow-up period was 41.6±28.2 (range: 18-120) months. Twenty-six patients (49.0%) had anterior uveitis, 22 (41.5%) had intermediate uveitis, and 5 (9.4%) had panuveitis. The mean duration of ADA treatment was 23.0±13.7 (range: 12-60) months. Uveitis flare-ups developed in only 13 patients (24.5%) while on ADA treatment. When pre- and post-treatment periods were compared, the mean number of uveitis flare-ups, intraocular inflammation severity, mean dose of topical and systemic CS, and mean CMT values were significantly lower in the post-treatment period (p<0.05). The mean BCVA was significantly improved after 6 and 12 months of ADA treatment compared to the pre-treatment visual acuity (p<0.05).

Conclusion

ADA effectively controlled intraocular inflammation, reducing the need for systemic and topical CS and improving visual outcomes in pediatric NIU.

Early Immunosuppressive Therapy and Ocular Complications in Pediatric and Young Adult Patients with Non-Infectious Uveitis at a Tertiary Referral Center in Japan

PURPOSE

To evaluate differences in the incidence of ocular complications among pediatric and young adult patients with non-infectious uveitis receiving immunosuppressive therapy (IMT), according to the time from uveitis onset to IMT initiation in Japan.

METHODS

Patients aged < 20 years exhibiting uveitis treated with IMT (e.g. methotrexate, cyclosporine, infliximab, or adalimumab) were categorized into three groups according to the time from uveitis onset to IMT initiation: ≤6 months, early IMT group; 7 months to 2 years, intermediate IMT group; and ≥ 2 years, late IMT group. The percentage of ocular complications was compared among these groups. Laser flare values were recorded to evaluate disruption of the blood-aqueous barrier (BAB).

RESULTS

Forty-three patients (84 eyes) who received IMT during the follow-up period were included. Among them, 28 patients (65.1%) experienced ≥ 1 ocular complication, with percentage of 56.0% in the early IMT group, 77.8% in the intermediate group, and 77.8% in the late group. Common complications were cataract (27.4%), posterior synechiae (17.9%), and macular edema (10.7%). The early IMT group did not require surgical intervention. The late IMT group experienced a high percentage of ocular complications despite IMT initiation. The mean laser flare value during follow-up was consistently higher in the late group (113.2 pc/ms) than in the early group (14.4 pc/ms) and intermediate group (28.7 pc/ms).

CONCLUSION

In pediatric and young adult patients with chronic non-infectious uveitis, early IMT initiation may prevent permanent breakdown of the BAB, reduce the incidence of ocular complications, and decrease the need for surgical intervention.

Monitoring compliance to topical therapy in children and young people with uveitis

BACKGROUND/OBJECTIVES

Uveitis in children and young people (CYP) is a rare but potentially debilitating condition. Steroid eye drops are the first step in treatment and poor compliance may result in vision-threatening complications. This study aims to measure compliance with prescribed eye drops prospectively in a child-specific manner.

SUBJECTS/METHODS

Patients aged 0-18 years attending a tertiary paediatric uveitis clinic using steroid drops were recruited. Both the CYP, and person with parental responsibility (PPR) completed questionnaires about compliance. A subgroup had bottles of Prednisolone 1% drops dispensed and weighed at the first appointment and reweighed at follow-up. The weight reduction was compared with expected weight change over the interval.

RESULTS

The study was completed by 42 patients of the 50 patients recruited. Thirty-one CYP and their respective PPR completed both questionnaires, 11 completed only one questionnaire (9 CYP, 2 PPR). Drop errors for all eye drops were reported more than "once a week" by 13/39 CYP (33.3%, 95% CI: 19.1%-50.2% of respondents), and 3/31 PPR (9.7%, CI: 19.1%-50.2% of respondents). Many PPR could not recall prescribed drop frequency (n = 13/31, 40.6%, CI: 23.7%-59.4% of respondents). Twelve patients had bottles weighed and returned. Insufficient weight reduction was found in 9 (75%, CI: 42.8%-94.5%). Within the eye drop weighing subgroup three participants (25%, CI: 5.5%-57.2%) used <50% the expected weight of drops.

CONCLUSIONS

This study demonstrated poor eye drop compliance in CYP with uveitis. Self-reported compliance was unreliable in this population. Worryingly, some patients miss more than 50% of drops and may suffer sub-optimal disease control.

Sarcoid Uveitis in Children

Sarcoidosis is a multi-system granulomatous disease that often presents with uveitis. Although sarcoidosis and sarcoid uveitis typically occur in adulthood, children also may be affected. There are two distinct clinical presentations of the pediatric disease, associated with younger and older age groups, and having different causations. "Early-onset sarcoidosis", beginning at age 5 years or less, is an autosomal dominant genetic disease, caused by a mutation in the NOD2 gene. It is also known as sporadic Blau syndrome or Jabs syndrome. "Adult-type sarcoidosis", usually beginning between the ages of 8 and 15 years, is believed to represent an excessive response to an environmental antigen. There is limited literature on the management of pediatric sarcoidosis, and treatment follows an approach applied to other forms of pediatric non-infectious uveitis. When systemic immunomodulatory therapy is indicated, methotrexate and/or adalimumab are often employed. The condition may persist into adulthood, and thus long-term follow-up is indicated.

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.
