ABSTRACT
OBJECTIVES: This study compared the incidence and time-to-event outcomes of ocular extraintestinal manifestations (O-EIMs) and EIMs among patients with human leukocyte antigen (HLA)-B27-associated diseases receiving different classes of immunotherapy.
METHODS: A retrospective cohort study was conducted using aggregated electronic health records from the TriNetX network between January 1, 2014, and December 31, 2024. Patients with HLA-B27-associated diseases were included if they were newly prescribed tumor necrosis factor (TNF), janus kinase (JAK), or interleukin (IL) inhibitors on or after their initial diagnosis. The cumulative incidence of O-EIMs and EIMs was calculated per 100 person-years. Kaplan-Meier estimates were used to graph time-to-event outcomes using R Studio (version 4.4.1).
RESULTS: We identified 22,287 patients [mean age 47.2 (16.8) years; 13,132 (58.9) % women]. The cumulative incidence of anterior uveitis from the index date was 0.11 cases per 100 person-years. According to first medication prescribed, the incidence of anterior uveitis was lowest in patients prescribed IL inhibitors, followed by JAK and TNF inhibitors (0.07%, 0.10%, and 0.20%, cases per 100 person-years respectively). Time-to-event analysis showed a higher likelihood of anterior uveitis with initial TNF inhibitor use, although the difference was not statistically significant. Regarding EIMs, incident sacroiliitis was highest with TNF (0.91%), followed by JAK (0.72%) and IL (0.37%). Psoriatic dermatitis incidence was highest with JAK inhibitors (2.85%), compared to TNF (2.19%) and IL (2.17%).
CONCLUSION: In this cohort study of patients with HLA-B27-associated diseases, the lack of statistical significance indicates similar effectiveness across immunotherapy classes in preventing O-EIMs and EIMs. Key Points • Large-scale comparative study assessing time-to-incident O-EIMs and EIMs in patients with HLA-B27-associated diseases treated with TNF, JAK, or IL inhibitor therapies using real-world data from the TriNetX network. • Low overall incidence of O-EIMs and EIMs was observed across all immunotherapy classes, with no statistically significant difference in time-to-event outcomes, indicating similar effectiveness in preventing these manifestations.
