Multi-drug resistance and side-effects in a patient with Behçet's disease.

OBJECTIVES: To report on the clinical course of ocular and extraocular involvement in a multidrug-resistant patient with Behçet's disease (BD).

METHODS: A 22-year-old male with BD (bilateral panuveitis and retinal vasculitis, oral ulcers, erythema nodosum, arthralgia, epididymitis) was followed-up from 1999 to 2014. He was treated continuously with corticosteroids in combination with different immunosuppressive therapies (cyclosporine, azathioprine, methotrexate, interferon, infliximab, mycophenolate), which exerted numerous side-effects such as nephrotoxicity, nephrolithiasis, increase of liver enzymes, severe depression with suicidal ideation, severe leucopenia, pulmonary tuberculosis, pulmonary legionellosis, recurrent bronchopneumonia.

RESULTS: Despite immunosuppressive and corticosteroid therapies, the patient showed multiple relapses of uveitis and systemic BD lesions and developed severe osteoporosis with multiple vertebral fractures, bilateral cataracts and steroid-associated glaucoma until 2007. Since then he has been treated with prednisone alone, currently at low dosage, remaining free from uveitis and systemic symptoms. His final visual acuity is 9/10 in the right eye and counting fingers in the left one.

CONCLUSIONS: BD patients are usually responsive to immunosuppressive drugs. The possibility of a multi-drug resistance as well as of multiple drug-related side effects cannot be disregarded and continuous therapy should be given in order to preserve a useful visual acuity until the disease, either spontaneously or drug-induced, runs into remission.
