[Off-label use of infliximab]

Abstract

Tumor necrosis factor α (TNFα) is a pro-inflammatory cytokine and a key mediator of inflammation. Several TNFα antagonists have been used therapeutically. One of them, infliximab, is a chimeric monoclonal antibody with anti-TNFα activity. Numerous studies have shown TNFα antagonists to be effective in treating psoriasis--particularly severe resistant forms--and arthritis. Additionally, several case reports and studies showing the effects of TNFα on new dermatologic indications have been published. The intention of this review is to summarize the new off-label uses of infliximab according to published data.
