Long-Term Outcomes of Adalimumab Treatment in Conventional Treatment-Resistant Serpiginous Choroiditis.

Abstract

Background/objectives: To investigate the long-term efficacy and safety of adalimumab(ADA) in the treatment of patients with serpiginous choroiditis (SC) refractory to conventional therapy through quantitative parameters.

Subjects/methods: A retrospective analysis was conducted on patients diagnosed with SC clinically and through fundus autofluorescence(FAF). Patients receiving ADA treatment were included. Demographic and clinical characteristics of the patients, association with tuberculosis (TB) infection, number of immunosuppressive therapies, recurrences, best corrected visual acuity (BCVA) change, and ADA-related side effects were recorded. The progression rate before and after ADA was calculated based on the area involved by FAF.

Results: Sixteen eyes of 8 patients (3 female/5 male) were enrolled to the study. The median (IQR) age was 53.5 (16.5) years. Diagnosis was SC in 4, ampiginous choroiditis in 3, and TB-related serpiginous-like choroiditis in 1 patient. Peripapillary involvement was present in 10 of 16 eyes. The area involved by FAF continued to progress under ADA treatment, however the progression rate was decreased (p = 0.143).The BCVA was preserved (p = 0.772). The number of systemic and local treatments decreased with ADA (p = 0.025 and 0.019, respectively). Additionally, the number of recurrences was reduced with ADA (p = 0.002). Median (IQR) follow-up was 45(28.75) months. Two patients experienced ADA-related side effects (pulmonary TBand rash).

Conclusions: Our findings suggest a promising role for ADA in halting the progression of SC and have implications for improving outcomes. Despite the evidence in the literature at the level of case reports, ADA can be used effectively with close monitoring for potential risks.
