Interleukin-2 (IL-2) and its receptor (IL-2R) play a central role in T lymphocyte activation and immune response after transplantation. Research on the biology of IL-2R allowed the identification of key signal transduction pathways involved in the generation of proliferative and antiapoptotic signals in T cells. The alpha-chain of the IL-2R is a specific peptide against which monoclonal antibodies have been raised, with the aim of blunting the immune response by means of inhibiting proliferation and inducing apoptosis in primed lymphocytes. Indeed, basiliximab, one of such antibodies, has proved to be effective in reducing the episodes of acute rejection after kidney and pancreas transplantation.The use of basiliximab was associated with a significant reduction in the incidence of any treated rejection episodes after kidney transplantation in the two major randomised studies (placebo 52.2% vs basiliximab 34.2% at 6 months, European study; placebo 54.9% vs basiliximab 37.6% at 1 year, US trial). Basiliximab and equine antithymocyte globulin (ATG) administration resulted in a similar rate of biopsy-proven acute rejection at 6 months (19% for both) and at 12 months (19% and 20%, respectively). The use of basiliximab appears not to be associated with an increased incidence of adverse events as compared with placebo in immunosuppressive regimens, including calcineurin inhibitors, mycophenolate mofetil or azathioprine and corticosteroids, and its safety profile is superior to ATG. Moreover, a similar occurrence of infections is noted in selected studies (65.5% after basiliximab vs 65.7% of controls), including cytomegalovirus infection (17.3% vs 14.5%), and cytokine-release syndrome is not observed. Finally, economic analysis demonstrated lower costs of overall treatment in patients treated with basiliximab.Therefore, the use of basiliximab entails a very low risk, allows safe reduction of corticosteroid dosage and reduces the short- and mid-term rejection rates. However, the improvement in the long-term survival of kidney grafts in patients treated according to modern immunosuppressive protocols is still to be demonstrated. These conclusions are based on a systematic review of the scientific literature, indexed on Medline database, concerning the mechanism of action, therapeutic activity, safety and pharmacoeconomic evaluation of basiliximab in renal transplantation.
