Intra-Articular Injections of Infliximab in the Treatment of Inflammatory Rheumatic Diseases: Case Reports and Review of Literature

Inflammatory chronic diseases involving joints together with other organs are usually treated with a systemic approach. In a few cases, where arthritis is not responsive to traditional treatments, an intraarticular (I.A.) therapy could be useful. Furthermore, patients not eligible for systemic therapy with anti-TNF or other DMARDs, as well as patients with an initial arthritis with the involvement of a single joint, such as the knee or hip joint, could use the I.A. injection therapy. In this article we report our experience with five patients affected by rheumatic inflammatory diseases, not responding to traditional systemic DMARDs-based therapies or not eligible for systemic use of biological response modifiers who underwent ultrasound-guided I.A. injection of Infliximab. Three of 5 patients showed a positive and long-lasting response to treatment with local Infliximab. Safety profile was good according to literature data. Moreover, in this article we review the literature on this therapeutic approach. This is the first report of I.A. use of Infliximab in the hip joint
