Efficacy and safety of immunomodulatory drugs in patients with non-infectious intermediate and posterior uveitis, panuveitis and macular edema: A systematic literature review.

BACKGROUND

Non-infectious non-anterior uveitis (NINA) is a sight-threatening condition that often requires immunomodulatory drugs (IMDs) for its management.

OBJECTIVES

To evaluate the published evidence regarding the use of IMDs in adult patients with NINA uveitis including intermediate (IU) and posterior uveitis (PU), panuveitis (PanU) and macular edema (ME).

METHODS

We performed a systematic literature review. Search strategies were designed for Medline, Embase, and Cochrane Libraries for articles up to 2019 to evaluate the efficacy and safety of the IMDs. A quality assessment was performed using the Jadad Scale.

RESULTS

Nineteen randomized clinical trials were selected from the 1,103 articles retrieved. Characteristics of patients, treatment dosages and outcome measures were heterogeneous. The outcomes most frequently analyzed were visual acuity (VA), macular thickness and vitreous haze (VH). Different IMDs were used at their usual dosages. Methotrexate (MTX), micophenolate mofetil, cyclosporine A (CsA), tacrolimus, adalimumab and sarilumab were effective in NINA uveitis. Rituximab combined with MTX was effective in PU. Interferon-β was superior to MTX, albeit with more adverse events in IU with ME. CsA was similar to cyclophosphamide (Cyc) in Behçet uveitis. Tacrolimus was safer and similar to CsA. Cyc was effective in serpiginoid choroiditis, but when combined with azathioprine in PU, but did not improve VA. Secukinumab did not prevent NINA uveitis recurrences, although intravenously it showed a higher response rate than when used subcutaneously. Daclizumab did not show any benefits in Behçet NINA uveitis.

CONCLUSION

Several IMDs and their combinations can be useful in treating NINA uveitis. The available studies were heterogeneous regarding patient characteristics and outcomes.
