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.

Drug Retention Rate and Causes of Discontinuation of Adalimumab in Uveitis: Real-World Data from the Biotherapies in Uveitis (BioÚvea) Study Group.

PURPOSE: To study the drug retention rate (DRR), causes, and predictors of discontinuation of adalimumab (ADA) in a real-world uveitis setting. DESIGN: Multicentric, nationwide, registry-based, ambispective, observational study. PARTICIPANTS: Patients treated with ADA for noninfectious uveitis (NIU) in the Biotherapies for Uveitis (BioÚvea) Spanish registry from November 2016 to November 2017. METHODS: Demographics, clinical data, timing, and reasons for discontinuation, if occurred, were recorded. The DRR and drug retention time (DRT) were estimated using the Kaplan-Meier method. Median follow-up was analyzed by reverse Kaplan-Meier. Log-rank test was used for comparisons. Cox proportional-hazards model (PHM) and propensity score matching were used to identify predictors for discontinuation due to inefficacy and adverse events. MAIN OUTCOME MEASURES: Drug retention rate and DRT. RESULTS: A total of 392 patients were analyzed, including 218 women. Median age was 39 (interquartile range, 25) years. Nonanterior uveitis was recorded in 242 patients. Median follow-up was 49.07 (0.97-131.67) months, median DRT (survival) was 69.3 months, and 14 patients were lost to follow-up. The DRR at 6, 12, 24, and 60 months was 92.97%, 87.68%, 76.31%, and 54.28%, respectively. Adalimumab was discontinued in 151 patients. Discontinuation was due to lack or loss of efficacy in 74 patients, adverse event in 34 patients, and sustained quiescence in 25 patients. Recorded adverse events included infections in 10 patients and malignant neoplasms in 3 patients. Concurrent classic immunomodulatory therapy (IMT) was given to 251 patients. We did not find DRT differences regarding the use of concurrent IMT. Adalimumab was prescribed as a second or greater biotherapy line in 76 patients who showed shorter DRT (P = 0.038). Starting ADA in nonbiotherapy-naive patients was a predictor for "discontinuation due to inefficacy," whereas undifferentiated uveitis was a predictor for "discontinuation due to adverse event." Drug retention time was significantly shorter when spared or intensified, mainly due to discontinuation after sustained quiescence. CONCLUSIONS: Drug retention rate of ADA in uveitis at 60 months was 54.28%, with a good safety profile. The use of concurrent IMT did not show a significant influence on DRT. The use of ADA as a second or further biotherapy could be predictive for discontinuation due to inefficacy. Undifferentiated uveitis may be prone to premature discontinuation of ADA due to adverse events.

Effect of corneal morphometry on dynamic contour and Goldmann applanation tonometry.

OBJECTIVES: To determine the effects on dynamic contour tonometry (DCT) and Goldmann applanation tonometry (GAT) of the power of the flattest and steepest corneal meridians, their orientation, central corneal thickness (CCT), mean overall corneal thickness, and the mean thickness of a circular zone centered at the corneal apex of 1 mm radius (zone I) and the mean thicknesses of several concentric rings also centered at the apex of width 1 mm (zones II to VI, respectively). METHODS: A total of 136 consecutive healthy eyes were examined. Two multivariate linear regression models were constructed, 1 for each tonometry system. In both models, the predictive variables were: keratometric power of the flattest and steepest axes, flattest axis (as one of the categories 0 to 30, 30 to 60, 60 to 90, 90 to 120, 120 to 150, and 150 to 180 degrees), CCT, mean overall corneal thickness (determined using the Pentacam), and mean thicknesses of corneal zones I, II, III, IV, V, and VI (determined using the Pentacam). RESULTS: The multivariate regression analysis (adjusted R=0.11; P=0.04) revealed that GAT was influenced by CCT [B=0.042; 95% confidence interval (CI), 0.002-0.085] and the mean thicknesses of zones I (B=0.996; 95% CI, 0.105-1.729), II (B=-1.688; 95% CI, -3.171 to -0.204), and III (B=0.718; 95% CI, 0.028-1.407), whereas DCT was solely affected by the mean thickness of zone II (B=-0.372; 95% CI, -0.728 to -0.016) (adjusted R2=0.13; P=0.02). CONCLUSIONS: Although DCT is only affected by the mean thickness of zone II, GAT is influenced by CCT and the mean thickness of zones I, II, and III.
