Clinical characteristics, treatment, and outcomes of nivolumab-induced uveitis.

BACKGROUND

Nivolumab has been linked to occurrences of uveitis, yet the clinical features associated with these episodes remain unclear. This study aimed to explore the clinical characteristics of uveitis induced by nivolumab and to offer guidance for its prevention, diagnosis, and treatment.

METHODS

We conducted a retrospective analysis by gathering case reports related to nivolumab-induced uveitis from both Chinese and English databases, covering the period from inception until 30 September 2024.

RESULTS

A total of 38 patients with uveitis were included, with a median age of 63 years (range 35 and 92). The onset of uveitis occurred between 1 week and 24 months post-administration, with a median onset time of 1.4 months. Blurred vision was the primary complaint among patients. Sixteen patients (42.1%) exhibited uveitis resembling Vogt-Koyanagi-Harada (VKH) disease. Bilateral uveitis was the most prevalent form (89.2%), followed by unilateral uveitis (8.1%). Anterior uveitis was the most frequently observed type (52.6%), succeeded by posterior uveitis (23.7%), panuveitis (21.1%), and intermediate uveitis (2.6%). Uveitis showed significant improvement or resolution following treatment with topical or systemic corticosteroids, with a median improvement time of 4 weeks post-therapy.

CONCLUSIONS

Uveitis is a relatively uncommon adverse effect of nivolumab, typically manifesting within 5 months of treatment. Prompt recognition of nivolumab-induced uveitis and appropriate management are crucial, as most cases are treatable.
