[Therapy of chronic non infectious uveitis]

[Anti-TNF-α in the treatment of uveitis in the Besançon Hospital]

BACKGROUND

Noninfectious chronic uveitis is a difficult-to-treat situation in which corticosteroids, immunosuppressive agents, and more recently, anti-tumor necrosis factor (TNF)-α are used to prevent and/or reverse severe visual impairment. This single-center retrospective study was designed to assess the use (indications, efficacy, and side effects) of anti-TNF-α agents in noninfectious uveitis.

PATIENTS AND METHODS

Eight patients were analyzed: three children (age, 7-15 years) and five adults (age, 27-44 years). Anti-TNF-α agents were etanercept (three patients), adalimumab (four patients), and infliximab (four patients). Diagnoses were Behçet's diseases (n=3), sarcoidosis (n=1), juvenile chronic arthritis (n=2), spondyloarthropathy (n=2), one of the latter two combined with Crohn disease. In all cases, anti-TNF-α therapies were prescribed because uveitis and/or associated disease were not under control.

RESULTS

Adalimumab and infliximab were effective for all patients. One patient with infliximab needed to add corticosteroids and immunosuppressive agents because of relapse. Etanercept was stopped in all cases due to a lack of effectiveness or a change in indication. In all patients, anti-TNF-α agents improved uveitis and the underlying systemic disease. In children, their use improved quality of life by corticosteroid weaning. Prescriptions did not comply with regulations for three children, because of age limits (etanercept, one; adalimumab, two). No adverse event was recorded.

CONCLUSION

In this short case series, anti-TNF-α agents were effective both on uveitis and the underlying systemic disease and were well tolerated in patients with noninfectious chronic uveitis.

Tumor necrosis factor-α-mediated severity of idiopathic retinal periphlebitis in young adults (Eales' disease): implication for anti-TNF-α therapy

Tumor necrosis factor-alpha (TNF-α) is a pleiotropic inflammatory cytokine. Tumor necrosis factor-alpha was evaluated in the serum samples of patients with idiopathic retinal periphlebitis in young adults (Eales' disease). Retinal periphlebitis was graded according to a new grading system based on severity of inflammation (grade 1-4). Quantification of the TNF-α levels was carried out using ELISA kit in the serum samples of young adults with idiopathic retinal periphlebitis (n = 17) and healthy controls (n = 17) of similar age. Tumor necrosis factor-α level was found to be significantly raised in cases with retinal periphlebitis as compared with controls (p < 0.001). Higher levels of TNF-α were found to be associated with increased severity of retinal periphlebitis. Tumor necrosis factor-α represents a novel target for controlling inflammatory activity in idiopathic retinal periphlebitis. Higher levels of TNF-α, in association with the increased severity of retinal periphlebitis, have implications for early anti-TNF-α therapy.
