PG - 3656-60 AB - Over the last 15 years, the use of various biological therapies has largely improved the way we manage patients with Inflammatory Bowel Diseases (IBDs). Blockade of cytokine synthesis and/or activity is at the forefront of this new era with the success of inhibitors of tumor necrosis factor (TNF)-alpha. These therapies are however not effective in all IBD patients and efficacy may wane. Moreover, patients treated with anti-TNF-alpha antibodies can develop severe side-effects and new immune-mediated diseases. Therefore, a new challenge is to elucidate new inflammatory networks in the IBD tissue and develop novel anti-cytokine compounds, which may act in patients who are resistant to or cannot receive anti-TNF-alpha therapies. In this article we review the available data supporting the pathogenic role of IL-23 and Th17-related cytokines in IBD, and discuss whether and how compounds that control the activity of these cytokines may enter into the therapeutic armamentarium of IBD.
