Purpose

To evaluate the outcomes of cyclophosphamide therapy for noninfectious ocular inflammation.

Participants

Two hundred fifteen patients with noninfectious ocular inflammation observed from initiation of cyclophosphamide.

Methods

Patients initiating cyclophosphamide, without other immunosuppressive drugs (other than corticosteroids), were identified at 4 centers. Dose of cyclophosphamide, response to therapy, corticosteroid-sparing effects, frequency of discontinuation, and reasons for discontinuation were obtained by medical record review of every visit.

Main Outcome Measures

Control of inflammation, corticosteroid-sparing effects, and discontinuation of therapy.

Results

The 215 patients (381 involved eyes) meeting eligibility criteria carried diagnoses of uveitis (20.4%), scleritis (22.3%), ocular mucous membrane pemphigoid (45.6%), or other forms of ocular inflammation (11.6%). Overall, approximately 49.2% (95% confidence interval [CI], 41.7%–57.2%) gained sustained control of inflammation (for at least 28 days) within 6 months, and 76% (95% CI, 68.3%–83.7%) gained sustained control of inflammation within 12 months. Corticosteroid-sparing success (sustained control of inflammation while tapering prednisone to 10 mg or less among those not meeting success criteria initially) was gained by 30.0% and 61.2% by 6 and 12 months, respectively. Disease remission leading to discontinuation of cyclophosphamide occurred at the rate of 0.32/person-year (95% CI, 0.24–0.41), and the estimated proportion with remission at or before 2 years was 63.1% (95% CI, 51.5%–74.8%). Cyclophosphamide was discontinued by 33.5% of patients within 1 year because of side effects, usually of a reversible nature.

Conclusions

The data suggest that cyclophosphamide is effective for most patients for controlling inflammation and allowing tapering of systemic corticosteroids to 10 mg prednisone or less, although 1 year of therapy may be needed to achieve these goals. Unlike with most other immunosuppressive drugs, disease remission was induced by treatment in most patients who were able to tolerate therapy. To titrate therapy properly and to minimize the risk of serious potential side effects, a systematic program of laboratory monitoring is required. Judicious use of cyclophosphamide seems to be beneficial for severe ocular inflammation cases where the potentially vision-saving benefits outweigh the substantial potential side effects of therapy, or when indicated for associated systemic inflammatory diseases.

Study Population

The Systemic Immunosuppressive Therapy for Eye Diseases Cohort Study is a multicenter cohort study for identifying long-term treatment adverse events, the methods of which have been described previously.33 For this report, all patients at 3 academic subspecialty centers with noninfectious ocular inflammation since the inception of the center and an approximate 40% random sample of such patients from a fourth center potentially were eligible. Sampling was carried out because of logistical

Results

Two hundred fifteen patients (77.2% with bilateral ocular inflammation; 381 eyes) were identified who started cyclophosphamide as a single immunosuppressive agent during follow-up, with or without local or systemic corticosteroids and nonsteroidal anti-inflammatory drugs. The demographic and clinical characteristics of this cohort are summarized in Table 1. The overall median age was 61.3 years (range, 11.5–91.4 years). Most patients were white (83.3%) and female (58.1%). The patients with

Discussion

This report confirms the beneficial effects of cyclophosphamide therapy for ocular inflammation. Cyclophosphamide was successful in achieving complete control of inflammation in 49.2% and 76.3% by 6 months and 12 months, respectively. Similarly, corticosteroid-sparing success (sustained control of inflammation while tapering prednisone to 10 mg or less) was gained by 30.1% and 61.2% by 6 and 12 months, respectively. At or before 2 years after initiation of treatment, 63% were able to
