Comparison of short-term outcomes with and without induction therapy in low-risk renal transplant recipients.

With low rates of rejection with current immunosuppression consisting of steroids, mycophenolic acid and tacrolimus, the question arises whether induction offers any additional benefit in low-risk renal transplant recipients. This study evaluated outcomes with and without induction in low-risk renal transplant recipients. A prospective observational study in which 100 low-risk renal transplant recipients were included and divided into two groups - one that received induction (IND) and another that did not (NO IND). They were followed for 1.5 years. Three endpoints were compared - efficacy of induction, patient and graft survival, and adverse effects. Incidence of rejection in early posttransplant period did not differ (4% NO IND vs. 6% IND; P = 0.171). Rejection as cause of late graft dysfunction was seen in 16% in IND vs. 20% NO IND; (P = 0.603). No difference in serum creatinine at end of 1.5 years was seen. Graft survival was also similar. Relapsing and recurrent urinary tract infections (46% IND vs. 16% NO IND; P = 0.09), hospitalization requiring infections (76%IND vs. 64% NO IND; P = 0.119 NS) were more common in IND. Cytomegalovirus infection affected only IND (6% vs. none; P = 0.07). Patient survival at 1.5 years was comparable (94% IND vs. 96% NO IND; P = 0.646). The study showed comparable results between IND and NO IND with however an increased incidence of infections and hospitalizations in the IND group. The use of induction may be avoided in low-risk renal transplant recipients.
