Acute Bilateral Anterior Uveitis following Cyclophosphamide/ Bortezomid/ Dexamethasone (CyBorD) Protocol in a Newly Diagnosed Multiple Myeloma Patient with Concomitant Use of Zoledronic Acid.

Purpose: To report a case of anterior uveitis in a patient under treatment with Cyclophosphamide / Bortezomid / Dexamethasone (CyBorD) protocol for Multiple Myeloma and concomitant use of Zoledronic acid.Methods: Observational case report of a 50-year-old woman presenting with acute, severe, bilateral uveitis on a medical history of Multiple Myeloma, undergoing the first cycle of CyBorD protocol, including infusion with Zoledronic acid.Results: Continuation of therapy, with parallel treatment with topical and per os steroids led to resolution of the inflammation. Three more chemotherapy cycles were performed with the same protocol including Zoledronic acid at a lower dosage and were all, uneventful.Conclusion: Our case mirrored uveitis cases with either masquerade syndrome due to Multiple Myeloma or following Zoledronic acid infusion, despite concomitant usage of Dexamethasone and Cyclophosphamide. Three consecutive rechallenges were performed without any topical prophylactic treatment and with no relapse of signs or symptoms.
