The superiority of different induction therapies after heart-lung and lung transplantation is not clearly established; specifically, whether monoclonal (OKT3) or polyclonal antibody induction therapy provides any advantage. Between 1989 and 1991 we used induction therapy with either rabbit antithymocyte globulin (RATG) or OKT3, given at random based on the availability of RATG. RATG was used in 25 @entity1 (RATG group 1) and OKT3 in 38 @entity1 (OKT3 group 1). Early results suggested a survival advantage with RATG. From 1992 until 1997 we used RATG induction therapy in 108 @entity1 (RATG group 2). This study analyzed longer-term survival, infection, rejection, and @entity5924 ( @entity5924 ) rates for RATG group 1 and OKT3 group 1 and assessed outcomes for RATG group 2. The 1-, 3-, and 5-year survival for RATG group 1 was 72 %, 72 %, and 52 % and for OKT3 group 1 was 63 %, 49 %, and 34 % (P < 0.05). The 1- and 3-year survival for RATG group 2 was 84 % and 74 %. The 1-, 3-, and 5-year actuarial freedom rates from lung rejection for RATG group 1 were 38 %, 38 %, and 31 % and for OKT3 group 1 were 21 %, 0 %, and 0 % (P < 0.01). The linearized rate (events/100 @entity1 days) of all @entity281 at 3 months was 1.55 +/- 0.28 for RATG group 1 and 2.19 +/- 0.27 for OKT3 group 1 (P = NS). The infection rate for RATG group 2 was 1.60 +/- 0.13. The actuarial rates of freedom from @entity5924 at 1, 3, and 5 years for RATG group 1 were 84 %, 51 %, and 45 % and for OKT3 group 1 were 77 %, 61 %, and 36 % (P = NS), while for RATG group 2 the rates were 97 % and 92 % at 1 and 3 years (P < 0.01 vs RATG group 1 and OKT3 group 1). The use of RATG induction therapy from 1989 through 1991 resulted in improved actuarial survival and less rejection, without increased infection rates. The use of RATG since 1992 has continued to result in similar outcomes for survival, infection, and rejection. The time to onset of @entity5924 has improved further in recent years. This may be a result of recent improvements in cytomegalovirus ( @entity2834 ) prophylaxis.
