Oral phospholipidic curcumin in juvenile idiopathic arthritis-associated uveitis.

Abstract

To evaluate the efficacy and the safety of curcumin-phosphatidylcholine complex in children affected by juvenile idiopathic arthritis-associated uveitis as an adjunctive treatment to chronic systemic immunosuppressive therapy. In this retrospective, longitudinal study, we treated patients affected by juvenile idiopathic arthritis-associated uveitis with residual low-grade inflammatory activity in the anterior chamber with one tablet of curcumin-phosphatidylcholine complex per day, over a year. Low-grade inflammatory activity was characterized by flare 1+ at slit-lamp examination and 10-50 photon counts per ms) at the FC500 laser flare meter. Inactivity of uveitis was defined as complete disappearance of flare at the slit-lamp examination and values <10 ph/ms at laser flare meter. Conversely, recurrence of the uveitis was defined as a one-step increase from baseline in anterior chamber cells levels or laser flare meter measurements >50 ph/ms. A total of 22 out of 27 patients (81%) achieved inactivity at the end of the study. Five patients (19%) did not show a significant reduction in anterior chamber flare, remaining stable throughout the follow-up. Only three episodes of flare-ups in three different patients were recorded. Overall, the treatment was well tolerated by all patients and no ocular discomfort, ocular side effects, or allergic reactions were registered. Adjunctive therapy with curcumin in patients affected by juvenile idiopathic arthritis-associated uveitis improves mild chronic anterior chamber flare and presents a good safety profile. Despite being mild, anterior chamber inflammation should be minimized to avoid the development of sight-threatening complications in these patients.
