title: Basiliximab as an alternative to antithymocyte globulin for early immunosuppression in lung transplantation.
abstract: OBJECTIVE
  Basiliximab (BAS), an interleukin-2 monoclonal antibody, has shown promising results as induction therapy in liver and kidney transplantation. We compared the efficacy and patient tolerability of BAS and antithymocyte globulin (ATG) in lung transplantation (LTx).
  
  
  METHODS
  The study included 37 patients in two groups (ATG and BAS, respectively). The indication for LTx was emphysema in 62.6% of patients in group 1 and 57.1% of patients in group 2. Mean (SD) patient characteristics compared in the two groups included age (52.0 [9.8] vs 54 [10.6] years), height (172.0 [10.1] vs 169 [7.55] cm), and weight (73.9 [15.3] vs 64.4 [14.2] kg) (P = .049). Induction therapy after LTx in the two groups was as follows: in 16 transplantation procedures (eight single and eight bilateral) performed between April 1998 and December 2002, ATG, 3 mg/kg/d for 3 days, was administered, and in 21 transplantation procedures (15 single and 6 bilateral) performed between January 2003 and July 2005, BAS, 20 mg on days 0 and 4, was given. Dosages of cyclosporine, azathioprine, and steroids for maintenance therapy were equivalent in the two groups. We retrospectively compared patient tolerability, occurrence of acute rejection or infection (from bacteria, cytomegalovirus [CMV], or Aspergillus), and outcomes between the two groups during 2 years of follow-up.
  
  
  RESULTS
  No cytokine-mediated reaction was observed in either group; however, there was a difference in hematologic effects. On day 2, mean (SD) platelet count was significantly lower in the ATG group at 113,500 (56,400)/mm(3) vs 151,900 (57,300)/mm(3) (P = .046). Because of severe thrombocytopenia, three patients could not be given ATG on day 3. The overall incidence of aspergillosis (18.8% vs 19.0%) and CMV infection (31% vs 57%) was similar in the two groups. However, when the recipient was CMV-positive and the donor was CMV-negative, the there was a clear trend (33.3% vs 88.9%). The number of acute rejection episodes was similar (43.8% vs 52.4%). Survival increased by 20% in the BAS group (P = .03).
  
  
  CONCLUSIONS
  In LTx, safety of BAS use is as good as or better than that of ATG, with no difference in acute rejection episodes or infections, with the possible exception of increased reactivation of CMV infection. Thus, BAS could be an alternative to ATG as induction therapy in LTx; however, further studies are necessary.
