Human Upper Extremity (Hand and Forearm) Allotransplantation
To establish hand transplantation as a safe and effective reconstructive strategy for the treatment of upper extremity amputations.
To reduce the risk of rejection and enable allograft survival while minimizing the requirement for long term high dose immunosuppression.
For this purpose, we propose to utilize the "Pittsburgh Protocol", which is an immunomodulatory strategy that has been implemented in solid organ transplants at UPMC. Early results in living related liver and kidney patients have confirmed that this protocol provides the means to allow graft survival with minimization of maintenance immunosuppression and even allows weaning of some patients from long-term immunosuppression.We hypothesize that a similar protocol can enable graft survival in highly immunogenic composite tissue allografts like hand transplants while reducing the number,dosing and/or frequency of immunosuppressive drugs associated with serious adverse effects.

Experimental: Hand Transplantation
Procedure: Hand Transplantation
This program is the primary site for a novel immune modulation protocol for hand and/or forearm transplantation using donor bone marrow stem cells. This protocol, otherwise called the "Pittsburgh Protocol" has been published and implemented in 8 hand/forearm transplantations. The Pittsburgh hand transplant program is the only center that has experience with the "Pittsburgh Protocol" to reduce the number and dosing of immunosuppressive drugs used to prevent rejection of hand/forearm transplants.
Suitable candidates will be identified via patient information brochures and via advertisements directed at upper limb amputees. For this purpose, a web-page will be constructed for free access by interested individuals. This website will be accessible through standard search engines. Interested potential subjects will be instructed to contact the investigator for an appointment. At the time of appointment, candidates will be first requested to complete a screening consent form (SCF) before undergoing further evaluation/medical screening procedures. The SCF includes a written consent to obtain PHI of the candidate. When the candidate visits UPMC he will undergo a consultation with the PI who will perform a thorough clinical assessment and explain in detail the treatment options, risks and benefits of the procedure. Candidates will be requested to complete a screening consent at this stage. Appropriate subjects will then undergo further medical screening procedures that include a number of examinations and investigations to determine their candidacy for hand transplantation. Prospective recipients who are selected based on results of screening procedures will be invited to review and sign the full informed consent form prior to being wait-listed for the procedure.
The screening tests include:
History and physical exam, including height and weight Urine pregnancy test for all female subjects of childbearing potential Complete blood count, differential, reticulocyte count, platelet count ABO type Liver function tests including SGPT or SGOT, serum bilirubin (total and direct), total protein, albumin, alkaline phosphatase and GGT, PT, PTT with INR Serum electrolytes and renal function panel to include the following: sodium, potassium, chloride, carbon dioxide, calcium, phosphorus, magnesium, glucose, creatinine and BUN Urinalysis and creatinine clearance test to determine GFR Infectious disease studies: HIV antigen, HTLV I-II antibody, antibodies to HIV 1 and 2, hepatitis C virus, syphilis, hepatitis B core antibody, and hepatitis B surface antigen titers are required Infectious disease titers: CMV, EBV, HSV, toxoplasmosis and VZV (IgG and IgM when indicated) Pulmonary function tests, including DLCO2 Chest X-ray EKG and MUGA scan or echocardiogram for determination of cardiac ejection fraction Sinus X-ray (if clinically indicated) CT scans (CT Angiography)/MRI studies (Functional MRI, Skeletal MRIs of hand/hips) as indicated by medical history and physical examination Ophthalmologic examination Dental consult Psychiatric evaluation
