Anti-TNF-? Therapy in Seven Patients with Behet's Uveitis
Behcet's disease (BD) is a chronic, relapsing, multisystem disease. In some patients, ocular involvement can lead to severe vision impairment despite immunosuppressive therapy. Since high levels of circulating TNF-? have been found both in peripheral blood and aqueous humor of patients with active BD, we evaluated the efficacy of anti-TNF-? therapy in seven patients with severe ocular involvement resistant to previous treatment. Seven patients with sight-threatening relapsing uveitis refractory to immunosuppressive regimens received intravenously infliximab, at a dose of 35 mg/kg, on week 024 and then every 68 weeks, in combination with low-dose prednisone and methotrexate or azathioprine. Efficacy was assessed in terms of number and severity of relapses of posterior uveitis, visual acuity, and reduction of corticosteroids and immunosuppressive drugs. After a mean follow-up period of 23 months, the total number of relapses dropped to 6, compared to the 21 observed in an equivalent period of time before treatment. The visual acuity improved in 4 eyes, while it remained stable in 9. Therapy with infliximab considerably reduced the required daily dose of both corticosteroids and immunosuppressive drugs. In our experience infliximab proved to be safe and effective in controlling both the number and intensity of cases of posterior uveitis and the extraocular manifestations of BD. It also allowed a reduction of corticosteroids and immunosuppressive drugs required to control the disease. However, ocular and systemic manifestations tended to recur after drug withdrawal or when the interval between infliximab courses was longer than 8 weeks. Moreover, infliximab administration is costly and requires hospital admission
