Interferon therapy for ocular disease.

PURPOSE OF REVIEW: Interferons were first known for their antiviral action. Immunomodulatory therapy with interferons has been studied in various diseases. This paper summarizes the role and presumed mechanisms of action of type 1 interferons in the treatment of ocular disease. RECENT FINDINGS: Preliminary data show beneficial effects of interferons in ocular disease such as Behçet disease and multiple sclerosis-associated uveitis in terms of visual acuity, intraocular inflammation activity, and chronic macular edema. Another mode of application is topical as an adjuvant treatment in viral keratitis or ocular surface malignancies. SUMMARY: Interferons are gaining a place in the treatment of ocular disease. Evidence is growing of their potential in ocular Behçet disease and multiple sclerosis-associated uveitis. Randomized, controlled clinical trials are needed to confirm this observation. Further insights into the complex mechanisms of action of interferons in health and disease will increase understanding of their mechanisms of action as a therapeutic substance.

Management of sight-threatening uveitis: new therapeutic options.

Over the past 2 decades therapy for the treatment of intraocular inflammation (uveitis) has developed into a highly differentiated approach with an increasing number of drug options. This paper primarily summarises literature from the past 5 years (2000 to May 2004), gives an update on systemic immunosuppressive therapy for non-infectious uveitis and speculates about new developments that could become relevant in the near future for the treatment of uveitis patients. The spectrum of immunosuppressive drugs has been notably expanded by tumor necrosis factor inhibitors, but with some limitations to uveitis. Behcet's disease is an example of uveitis where a multisystem disorder can affect the eye very severely. This clinical example has been used to investigate the utility of many different types of immunosuppressive therapies and the clinical approach is extensively discussed in this review. An accompanying table summarises the proposed mode of action, standard dosage, common adverse effects, as well as estimated cost of current treatment options.

Lack of evidence for inhibition of angiogenesis as a central mechanism of the antiarthritic effect of methotrexate.

OBJECTIVES: The aim of this study was to investigate whether methotrexate (MTX) has an antiangiogenic effect and whether this property plays a role in the control of rheumatoid arthritis (RA). METHODS: A human placenta angiogenesis assay was used to examine the antiangiogenic effects of MTX in vitro. In addition, DBA/1 mice were used to compare the antiarthritic effect of MTX in collagen-induced arthritis (CIA) and its antiangiogenic effect in a murine in vivo matrigel model for angiogenesis. RESULTS: The spreading of microvessels from placental vessel fragments was not significantly inhibited by MTX. Treatment with MTX reduced significantly the incidence of CIA in DBA/1 mice in a dose-dependent manner. However, treatment with the same doses of MTX did not significantly reduce vessel growth in subcutaneous depots of bFGF-enriched matrigel. CONCLUSION: These data support the hypothesis that inhibition of angiogenesis does not significantly contribute to the antiarthritic effect of MTX seen in patients and animal models for RA. Therefore, the combination of MTX with antiangiogenic drugs appears to be a rational strategy in the treatment of RA.
