Initial experience of dual maintenance immunosuppression with steroid withdrawal in vascular composite tissue allotransplantation.

Current immunosuppression in VCA is largely based on the experience in solid organ transplantation. It remains unclear if steroids can be reduced safely in VCA recipients. We report on five VCA recipients who were weaned off maintenance steroids after a median of 2 months (mean: 4.8 months, range 2-12 months). Patients were kept subsequently on a low dose, dual maintenance consisting of tacrolimus and mycophenolate mofetil/mycophenloic acid with a mean follow-up of 43.6 months (median = 40 months, range 34-64 months). Early and late acute rejections responded well to temporarily augmented maintenance, topical immunosuppression, and/or steroid bolus treatment. One late steroid-resistant acute rejection required treatment with thymoglobulin. All patients have been gradually weaned off steroids subsequent to the treatment of acute rejections. Low levels of tacrolimus (<5 ng/mL) appeared as a risk for acute rejections. Although further experience and a cautious approach are warranted, dual-steroid free maintenance immunosuppression appears feasible in a series of five VCA recipients.

Abdominal wall reconstruction using a non-cross-linked porcine dermal scaffold: a follow-up study.

PURPOSE: In a previous study, we have shown that non-cross-linked porcine dermal scaffolds (NCPDS) are a safe and effective alternative to prosthetic mesh in the reconstruction of complicated abdominal wall defects. Here, we report the long-term outcomes of abdominal wall reconstruction using NCPDS in a larger patient population. METHODS: Patients who underwent abdominal wall reconstruction with NCPDS between May 2006 and December 2010 were retrospectively reviewed. Analysis of demographics, indications for NCPDS placement, surgical technique, complications, and follow-up data was performed. RESULTS: NCPDS was used for abdominal wall repair in 40 patients. In all patients, NCPDS was positioned using an intraperitoneal technique. At a mean follow-up time of 40.1 months, most patients had successful outcomes. Complications included seroma (21 %), recurrence (7.9 %), and infection (5.2 %); these rates are comparable to our initial report. Two patients died from multi-organ failure unrelated to NCPDS placement. CONCLUSIONS: This study shows that complex abdominal wall defects can be successfully reconstructed using NCPDS with a low rate of recurrence and complications.

Evolution of indications for facial transplantation.

Face transplantation has the unique potential to restore facial form and function in patients with severe facial defects. Current indications for face transplantation remain limited by unknown long-term outcomes and the requirements for lifelong immunosuppression and substantial plans for reconstruction in case of failure. We initially obtained Institutional Review Board approval for partial face transplantation in patients with defects comprising 25% of the face and/or loss of one or more major facial features. We launched an outcome-oriented face transplantation study and screened 13 potential patients between February 2008 and January 2011. Experience gained during screening motivated the expansion of indications to include full facial defects and the consideration of patient-specific complex issues on a case-by-case basis. Although our programme focuses on restoring absent or severely compromised motor and sensory functions, we recognise aesthetic appearance as a crucial facial function. Patients are extensively educated on the risks and benefits of facial transplantation and then allowed to play the main role in the decision-making process, as long as no absolute exclusion criteria are present. As we learn more about the long-term outcomes of face transplantation and safe reduction of immunosuppression, face-transplant indications may expand from major unreconstructable defects towards potentially minor defects.

A multidisciplinary protocol for face transplantation at Brigham and Women's Hospital.

Face transplantation introduces an unprecedented potential to restore form and function in patients with severe facial disfigurement. A successful face transplantation programme requires a sound research protocol, a solid infrastructure, expert personnel and adequate funding. There are only a few active face transplant programmes in the world and interest in the development of new such programmes continues to grow. After 2 years of working on the development of the face transplant programme, in 2009 the team at Brigham and Women's Hospital (BWH) performed the 2nd face transplant in the United States. Since then, the team has continued to evaluate several possible face transplant candidates and performed three additional facial transplants. These experiences have helped refine a highly effective multidisciplinary protocol that carries a patient through recruitment, informed consent, screening, preoperative planning, face transplantation surgery and postoperative long-term follow-up. The members of the BWH face transplantation team responsible for carrying out this protocol include a team leader, a programme manager/coordinator, clinical and rehabilitation specialists, social workers, bioethicists, nurses and administrative staff. The roles of each team member during the various stages of the face transplant process are presented here. Additional insight into the interaction between the face transplant team, the Institutional Review Board and the regional Organ Procurement Organization is given. The BWH team's experience has shown that true collaboration, creativity and a unique approach to each candidate translate into the optimal care of the face transplant patient both before and after surgery.
