Background
Immunosuppression regimens used in the field of VCA are commonly based on regimens used for kidney transplantation. Most programs, strive to use the least amount of immunosuppression that will protect the graft, while limiting complications. Our program has attempted to wean maintenance prednisone use in 7 of 8 hand transplant recipients.
Methods
Eight patients have received 9 hand transplants with a follow up of 9 months to 15 years (mean follow up 2003 days +/− 1918 days). Seven patients received a unilateral hand transplant and patient 6 received a bilateral hand transplant. Patient 4 lost his graft at 9 months due to ischemia secondary to vasculopathy, and patient 6 was lost to follow up at day 283. All recipients were male, (mean age of 50 +/− 8). All patients received induction and 5/8 were started on triple drug immunosuppression at the time of transplant.
Results
As shown in the table, the 6 hand recipients currently being followed at our program 4/6 have been weaned off steroids, and have never required treatment for rejection, or that steroids be restarted. In all 4 of these cases, weaning occurred one year post transplant or later. In 2 cases where prednisone was never started, or started late, significant rejection and vasculopathy was observed. However, patient 6 who was never weaned from steroids also had vasculopathy and rejection.

Conclusion
In our experience, patients who have a relatively quiet clinical course for the first year post transplant can be weaned off prednisone, and have done well. Additionally, patients who are significantly farther than one year post transplant can be successfully weaned off prednisone and maintained on Prograf and Sirolimus or Prograf and MMF dual therapy.
