[Interferons and Behçet's disease].

BACKGROUND

Behçet's disease is a vasculitis of unknown origin. Various therapeutic agents have been proposed. Interferon alpha 2a or 2b appear to be the most promising.

CURRENT KNOWLEDGE AND KEY POINTS: Numerous anecdotal reports and some short series have shown the efficacy of interferon in some cases previously resistant to conventional therapy, particularly to immunosuppressors. Posology, depending on the author, may vary from three million three times a week to 18 million three times a week. Interferon alpha is useful in cases of ocular, muco-cutaneous and articular involvement. Data is lacking for digestive, vascular and neurological manifestations.

FUTURE PROSPECTS AND PROJECTS: Multicenter trials will nevertheless be required to determine the duration of therapy, risk of relapses, associated therapy and the optimal time to commence interferon treatment.
