Recurrent grade 4 panuveitis with serous retinal detachment related to nivolumab treatment in a patient with metastatic renal cell carcinoma

Abstract

Blockade of programmed cell death-1 (PD-1) has become one of the most promising immunotherapies for many human cancers. However, immune-related adverse events can be produced by anti-PD-1 therapy. Uveitis is a rare but potentially devastating side effect of anti-PD-1 therapy. Delay in diagnosis or improper treatment may eventually lead to irreversible blindness. Therefore, it is important for the oncologist and the ophthalmologist to recognize and manage this adverse event properly in patients receiving anti-PD-1 therapy in a timely manner. Here we present a grade 4 panuveitis with bilateral serous retinal detachment following treatment with nivolumab for metastatic renal cell carcinoma. Oral prednisone, topical steroid eye drops, periorbital injection of steroid and finally intravitreal injection of steroid implant were administered in our patient. We observed that intravitreal injection of dexamethasone implant, but not the periorbital injection of steroid or the steroid eye drops, was effective to control the posterior uveitis and serous retinal detachment. Oral prednisone was also effective, but it might affect the efficacy of anti-PD-1 therapy and promote tumor growth. We also summarize 15 cases of uveitis reported to date related to nivolumab or pembrolizumab therapy in the present study. The symptoms, signs, potential underlying mechanisms and treatment options regarding this adverse event are discussed.
