[Therapeutic strategy for the treatment of non-infectious uveitis proposed by an expert panel]. / Avis d'experts pour le traitement des uvéites non infectieuses.

Conventional immunosuppressive drugs, anti-TNF alpha and other biotherapies used in clinical practice are capable of controlling non-infectious anterior uveitis, posterior uveitis and panuveitis. The present work has been led by a multidisciplinary panel of experts, internists, rheumatologists and ophthalmologists and is based on a review of the literature. In case of corticodependency or sight-threatening disease, conventional immunosuppressive drugs (methotrexate, azathioprine and mycophenolate mofetil) and/or anti-TNF alpha (adalimumab, infliximab) are used to achieve and maintain remission. Interferon is an efficient immunomodulatory treatment, as a second-line therapy, for some therapeutic indications (refractory macular edema, Behçet's vascularitis). Other biologics, especially tocilizumab, are showing promising results. Local treatments (corticosteroids, sirolimus etc.) are adjuvant therapies in case of unilateral inflammatory relapse. Therapeutic response must be evaluated precisely by clinical examination and repeated complementary investigations (laser flare photometry, multimodal imaging, perimetry, electroretinography measures).

Biotherapies in inflammatory ocular disorders: Interferons, immunoglobulins, monoclonal antibodies.

Biotherapies used in clinical practice for the treatment of ophthalmologic manifestations of systemic diseases include interferons (IFN), intravenous immunoglobulins (IVIG) and monoclonal antibodies (anti-TNF, anakinra, tocilizumab and rituximab). Several open prospective studies have shown the effectiveness of IFN-α (78 to 98% complete remission) for the treatment of severe uveitis in Behcet's disease. IFN is capable of inducing prolonged remission and continued after his arrest, in 20-40% of patients. Side effects (flu-like, psychological effects) limit its use in practice. Anti-TNFα (infliximab and adalimumab) represents an attractive alternative therapeutic in severe uveitis refractory to immunosuppressants, especially in Behcet's disease. They are almost always (>90% of cases) and rapidly effective but their action is often suspensive. Anti-TNFα requires an extended prescription or takes over from another immunosuppressant once ocular inflammation has been controlled. IVIG are used for the treatment of Kawasaki disease and Birdshot disease. Several open or retrospective studies showed their effectiveness for the treatment of severe and refractory cicatricial pemphigoid. Tolerance of IVIG is good but their efficacy is transient. Rituximab showed an efficacy in few observations of various inflammatory eye diseases (uveitis, scleritis and idiopathic inflammatory pseudo-tumors or associated with granulomatosis with polyangiitis) and cicatricial pemphigoid. The risk of infection associated with this biotherapy limits its use in refractory diseases to conventional therapy. Anakinra (a soluble antagonist of IL-1R) showed interesting results in terms of efficiency in one small open study in Behcet's disease. Its safety profile is good and with a quick action that could be interesting for the treatment of severe uveitis.
