Methotrexate therapy for ocular cicatricial pemphigoid.

Abstract

To report the use of methotrexate therapy as first-line systemic therapy in the treatment of ocular-cicatricial pemphigoid and drug-induced ocular-cicatricial pemphigoid. Retrospective, noncomparative, interventional case series. Twelve patients with ocular-cicatricial pemphigoid and 5 patients with drug-induced ocular-cicatricial pemphigoid treated with low-dose oral methotrexate as the sole systemic agent. In 14 of the 17 patients, methotrexate was the first systemic agent used. Clinical data abstracted from patient medical records. Visual acuity, conjunctival inflammation, progression of cicatrization, and treatment-related side effects. After a mean follow-up duration of 30.2 months (range, 6-78 months), complete control or suppression, or both, of conjunctival inflammation was achieved in 89% of eyes with ocular-cicatricial pemphigoid and in 100% of eyes with drug-induced ocular-cicatricial pemphigoid using methotrexate monotherapy as the first-line systemic agent. Progression of conjunctival cicatrization was prevented in 72% of eyes with ocular-cicatricial pemphigoid and 90% of eyes with drug-induced ocular-cicatricial pemphigoid. Visual acuity was maintained or improved in 85% of total eyes treated with methotrexate monotherapy, and a final visual acuity of 6/18 or better was achieved in 74% of the eyes. Methotrexate therapy was well tolerated, with 92% of patients maintained on continued treatment experiencing no side effects. The most common side effects were gastrointestinal (50%), and most (78%) were reversible on dose reduction. In 4 of 17 cases, methotrexate was ceased as a result of possible treatment-related side effects. Low-dose oral methotrexate monotherapy is both highly efficacious and well tolerated as the first-line systemic agent in the treatment of ocular-cicatricial pemphigoid and drug-induced ocular-cicatricial pemphigoid.
