Background: This study aimed to compare the clinical outcomes of intestinal transplantation (ITX) between 2 groups by using medications for induction treatment and assess the utility of the current protocol.
Methods: From 2003 to 2020, 11 patients underwent ITX. Recipients were classified into 2 groups: group IL-2Ra (interleukin-2 receptor antagonist therapy, n = 6) and ATG (rabbit antithymocyte globulin therapy, n = 5). We conducted a retrospective review of patient and graft survival rates and the postoperative course.
Results: The 1-, 5-, and 10-year patient and graft survival rates of the 11 primary grafts in the 11 recipients were 100%, 88.9%, 62.2% and 90.0%, 78.8%, 56.3%, respectively. The median duration of follow-up for the IL-2Ra and ATG groups was 197.3 and 87.3 months, respectively. The 1-, 5-, and 10-year patient survival rates were 100%, 83.3%, 50% and 100%, 100%, 100% for the IL-2Ra and ATG groups, respectively (P = .25) and 83.3%, 66.7%, 33.3% and 100%, 100%, 100% for graft survival in the IL-2Ra and ATG groups, respectively (P = .08). The incidence of moderate and severe acute rejection was 100% and 20% in the IL-2Ra and ATG groups, respectively (P = .02). The 1- and 5-year moderate and severe rejection-free survival rates were 33.3%, 0% and 80%, 80% in the IL-2Ra and ATG groups, respectively (P = .04).
Conclusions: ATG significantly suppressed moderate and severe acute rejection compared with IL-2Ra, thereby showing better short- and mid-term rejection-free survival rates. Additional clinical experience is needed to determine the optimal regimen for the management of ITX recipients.
