This surgical procedure was successful although the patient did not adhere to the immunosuppressive management, nor to physical therapy; therefore, the patient required amputation of the graft in This was related to the motivation and ability to incorporate transplantation experience in patients, which may lead to non-compliance with the pharmacological or rehabilitation regimen 77, Some of the risk factors identified in psychological assessments in candidates for hand transplantation include social isolation, shame, decreased self-esteem, depressive coping style and poor quality of life For this reason, it is important to conduct a detailed psychiatric interview in which transplantation is addressed, and to supplement it with psychological tests to assess body image adaptation and integrity, before and after the transplant This is useful to perform the necessary therapeutic interventions, detect difficulties in the psychological integration process of the graft and, thus, obtain the best possible results in the long term.
Rehabilitation Although part of the success of hand transplantation is attributed to surgical planning, it is not the only aspect to be taken into account to achieve a successful outcome Rehabilitation programs are fundamental for the recovery of functionality in the transplanted hand, since a successful process requires patient commitment. It is also necessary to ensure that the patient will count on a team of experts that can provide guidance in terms of long-term recovery goals and expectations Before transplantation, therapists collect data on motion range, strength, stump sensitivity, and history of prosthesis use.
They also find out if the patient feels pain, which is recorded by analogous verbal scale As for the team of hand therapists, they should be responsible for the planning of therapy sessions, patient education and familiarization with information from transplant centers 32which allows them to know the main complications and possible management.
In addition, it is recommended to initiate therapy one week after surgery. However, this therapy should be performed five days a week for an average of four hours a day for the first three months after transplantation 48which requires commitment from the patient and the caregiver. Likewise, since the intensity in days and hours varies among patients, they should be adjusted based on recovery in each case 90, Research on the emotional aspects of these patients has focused on depression, anxiety, personality disorders and substance abuse, since they are the most frequent alterations, and are associated with functionality recovery expectations after the transplantation 92, With this is mind, the need to assess the degree of satisfaction and improvement of the quality of life of transplanted patients arises.
These aspects are assessed through evaluation questionnaires that have not been standardized yet in all hand-transplantation programs Finally, the role of the caregiver is fundamental during the first post-transplantation phase, since patients, especially those receiving bilateral hand transplants, depend on someone else for daily living activities for weeks or months after the surgery.
This is exacerbated by the physical fatigue caused by rehabilitation, immunosuppressive drugs and the emotional challenges of the demanding general program Therefore, throughout the process, the family must be included to be provided with the necessary tools to meet this challenge in the best possible way.
State of the art Information on the experience of each transplant center in the world is compiled by the International Registry of Hand and Composite Tissue Transplantation IRHCTTwhere reports are delivered voluntarily non-mandatory. In total, 89 hand transplantations were performed between and The last report was published in and provides data on the follow-up of 49 hand transplantations in 33 patients 18 bilateral and 17 unilateral. Follow-up was performed on 31 patients for minimum one year; the age range was 19 to 54 years, with a mean age of 32 years.
Regarding sex, 31 patients were males. As a result, 30 patients regained tactile and discriminative sensitivity. Motor recovery was initiated in the extrinsic muscles gross motorand then in the intrinsic muscles of the hand, for 9 to 15 months, in most transplanted patients This motor return depends on the anatomical level of the transplant distal is better than proximaland on the postoperative rehabilitation regimen; sensory feedback is conditioned to the regeneration of the nerve Moreover, the systematic review by Landin et al.
Significant functional gains of the transplanted limb were also evidenced The main complications associated with transplantation are Seven of these patients lost the grafts due to lack of adherence to the treatment.
Overall, the results were poor, compared to transplantations performed in other centers around the world. When comparing unilateral and bilateral transplantation with DASH scores, better functional results were observed in bilateral transplants. Future of hand transplantation Despite advances in immunosuppressive management and rehabilitation programs, there are still limitations, such as nerve regeneration of the transplanted hand, which occurs both at the distal and proximal levels.
The case of proximal segment amputations is more relevant due to the difficulty of adapting to the prosthesis, which is why the transplant is required. Nevertheless, new research is expected to develop strategies to improve this aspect 3, Immunosuppressive protocols are another important factor in hand transplantation, since there would be no graft survival without them.
Currently, no protocols develop immunocompetence in the transplanted patient to avoid immunosuppression. Thus, these strategies are expected to be established in the future, to prevent the side effects of pharmacological immunosuppression. It should be noted that protocols that include transient or sustained chimerism have already been developed; however, in this case a living donor is needed, which is not possible in hand transplantation Today, research on autotransfusion protocols and mesenchymal stem cells that regulate the possible decline of the immune response can be found, even if its use is limited to experimental studies.
Although the use of mesenchymal bone marrow cells has shown to generate stable chimerism and prolong transplant survival in animal models, it has not yet been tested in humansAnother modality under study is based on the use of bioreactors to prolong ex vivo, that is, outside the donor and the recipient, in an alternate environment, to extend the survival of the graft and to modulate its immunogenicity so as to improve the function of the graft It has also been mentioned that patients undergoing hand transplantation have a history of difficulty to adapt to prostheses, despite their interest and the interventions made by specialists to achieve this goal.
This entailed high rejection rates of these devicesThe options offered to patients with amputations of upper limbs have changed and expanded in order to cover the physical demands of potential candidates. At present, advances have been made in prostheses adaptation and management, such as the case of selective muscular reinnervation in proximal amputation cases, which has allowed to develop the perception and position of the amputated segment. This technique consists of using non-functional muscles as amplifiers of the non-functional nerves and, thus, extending the nerve cover as distal as possible, approaching the distal end of the prosthesisHowever, the main causes of prostheses abandonment include adaptation difficulties, lack of participation in the selection of the prosthesis, functionality, patient expectations and education on the proper use of the prosthesis.
Thus, people who participate in the selection of devices are more successful in adherence to their everyday use. In addition, there are six options in the market for the patients with upper limb amputation: Choices must be made with the patient, so that proper assessment and advice can be provided for a correct selection Because the devices do not fulfill all the activities of daily life, and to be able to respond to the demands of the users and their profession, it is necessary to use more than one device.
To be successful and to meet patient expectations, their opinion on the process is essentialFinally, hand transplantation and prosthesis adaptation should not be seen as mutually exclusive, but as treatment options that differ from the risk and benefit profile for the patient, and from their ethical, clinical, aesthetic and functional implications Conclusions Hand transplantation, rather than a composite tissue transplant, should be considered as an organ transplant that depends on the comprehensive management by a multidisciplinary team, which requires a support network and motivation from the patient, along with compliance with pharmacological management.
When rejection occurs, it should be classified in order to determine the treatment. In consequence, a skin biopsy is considered as the gold standard for diagnosing acute rejection, although its role in chronic rejection should be questioned, since it can generate false negatives according to the depth of the sample.
Also, rehabilitation is a vital process to recover the functionality of the hand, as well as psychological accompaniment to prevent graft loss due to lack of adherence to the treatment. Finally, new research is expected to create strategies to develop tolerance and thereby reduce management through immunosuppression.
In addition, the pros and cons of hand transplantation, the experience of the transplant group, the side effects of short- and long-term drugs, and the possible complications associated with immunosuppression in each of the hand VAC cases should always be evaluated.
