Use of infliximab in the treatment of peripheral ulcerative keratitis in Crohn disease.

Abstract

To report the effectiveness of infliximab in the treatment of peripheral ulcerative keratitis (PUK) associated with Crohn disease. Retrospective, interventional case series. Institutional, academic referral setting. patient or study population: Six eyes of 3 patients with PUK associated with Crohn disease that failed or were intolerant to traditional immunosuppression such as oral prednisone and cyclophosphamide. INTERVENTION OR OBSERVATION PROCEDURE(S): Infliximab intravenous infusion 5 mg/kg every 2 to 8 weeks. Subjective outcome such as pain improvement and objective outcomes such as visual acuity, signs of inflammation, and progression of corneal thinning. Symptom of pain improved in all patients. Visual acuity remained stable in 4 of 6 eyes, improved in 1 of 6 eyes, and worsened in 1 of 6 eyes (secondary to stromal scar). Rapid resolution of inflammation and arrest of further thinning were observed in all 6 eyes. Similar effects were observed on recurrence treated with repeat dosing of infliximab in 5 of 6 eyes. Infliximab produced a rapid, dramatic, repeatable suppression of corneal inflammation, pain, and keratolysis in PUK associated with Crohn disease. Although the effect of long-term therapy with these agents is unknown, infliximab should be considered in patients with Crohn-associated PUK not amenable to traditional therapy. Larger prospective studies are needed to determine the efficacy of infliximab in this aggressive disease entity.
