Abstract

Purpose:

Management of granulomatosis with polyangiitis (GPA)–associated peripheral ulcerative keratitis (PUK) is challenging and lacks definite guidelines. We aimed to summarize our treatment and outcome experience with patients with GPA-PUK.

Methods:

The Massachusetts Eye Research and Surgery Institution patient database was searched from 2005 to 2015 to identify patients with diagnosis of PUK who suffered from GPA. Individual patient histories were examined, and treatment strategies and outcomes were summarized.

Results:

There were 16 patients who started treatment with a mean duration follow-up of 64 months (range: 12–110 mo). Rituximab and cyclophosphamide, either alone or in combination with other agents, were the most successful agents in controlling inflammation. Rituximab was administered in 11 patients with remission being achieved in all. Cyclophosphamide successfully controlled inflammation in 50% (5/10). Two of the patients (2/5, 40%) who had achieved initial control on cyclophosphamide had flares of their PUK. Two of 11 (18%) patients on rituximab had flares of scleritis and orbital inflammation but not PUK. Two patients, one in each treatment group, stopped treatment after achieving remission after 6 months of therapy but suffered disease recurrence within 2 months of treatment cessation.

Conclusions:

Rituximab achieved a high rate of disease control in PUK patients with GPA and is the preferred agent in halting disease progression.
