  • Advances in Immunosuppression for Renal Transplantation Antoine Durrbach, Helene Francois, Severine Beaudreuil, Antoine Jacquet and Bernard Charpentier
    REVIEWS Advances in immunosuppression for renal transplantation Antoine Durrbach, Helene Francois, Severine Beaudreuil, Antoine Jacquet and Bernard Charpentier Abstract | The development of immunosuppressants with minimal adverse and nephrotoxic effects is important to improve outcomes, such as acute and chronic antibody-mediated rejection, after organ transplantation. In addition, the application of expanded criteria for donors and transplantation in immunized patients necessitates the development of new therapies. Drug development over the past 10 years has generally been disappointing, but several new promising compounds have been or are being developed to prevent acute and chronic transplant rejection. In this Review, we report on several compounds that have been developed to remove allogenic T cells and/or to inhibit T-cell activation. We also discuss compounds that interfere with antibody-mediated rejection. Durrbach, A. et al. Nat. Rev. Nephrol. 6, 160–167 (2010); published online 2 February 2010; doi:10.1038/nrneph.2009.233 Introduction Renal transplantation has specific features that make or as a result of previous transplantation, has increased it different from transplantation procedures for other over the past decade.

Email: [email protected] Received: 14 July 2015, Revised and Accepted: 24 August 2015 ABSTRACT Psoriasis is an autoimmune disease and further classed as a chronic inflammatory skin condition serving as a global burden. A moderate to severe psoriasis can be treated with conventional therapies. Less efficacy, poor patient compliance, and toxicity issues were the major problems associated with conventional therapies. The introduction of biologic therapy has a great impression on psoriatic treatment duration and enhanced quality of life in psoriasis patients. The new biologic therapies are tailor-made medications with the goal of more specific and effective treatment; less toxicity. The biologic therapy is aimed to target antigen presentation and co-stimulation, T-cell activation, and leukocyte adhesion; and pro-inflammatory cascade. They act as effective and safer substitute to traditional therapy. Secukinumab, certolizumab, itolizumab, golimumab, ustekinumab, adalimumab, infliximab etanercept, alefacept, etc. are the approved biologic with the global market. This review briefs about psoriasis pathogenesis, traditional treatments, and biologic therapies potential. Keywords: Psoriasis, Biologic, Non-biologic treatment.

Kevin Park1 Abstract | Immunomodulatory biologics, which render their therapeutic effects by modulating or harnessing immune responses, have proven their therapeutic utility in several complex conditions including cancer and autoimmune diseases. However, unwanted adverse reactions — including serious infections, malignancy, cytokine release syndrome, anaphylaxis and hypersensitivity as well as immunogenicity — pose a challenge to the development of new (and safer) immunomodulatory biologics. In this article, we assess the safety issues associated with immunomodulatory biologics and discuss the current approaches for predicting and mitigating adverse reactions associated with their use. We also outline how these approaches can inform the development of safer immunomodulatory biologics.
