RESUMO

Ten years after the first face transplantation, we report the partial loss of this graft. After two episodes of acute rejection (AR) occurred and completely reversed in the first posttransplantation year, at 90 months posttransplantation the patient developed de novo class II donor-specific antibodies, without clinical signs of AR. Some months later, she developed several skin rejection episodes treated with steroid pulses. Despite rapid clinical improvement, some months later the sentinel skin graft underwent necrosis. Microscopic examination showed intimal thickening, thrombosis of the pedicle vessel, and C4d deposits on the endothelium of some dermal vessels of the facial graft. Flow magnetic resonance imaging of the facial graft showed a decrease of the distal right facial artery flow. Three steroid pulses of 500 mg each, followed by intravenous immunoglobulins (2 g/kg), five sessions of plasmapheresis, and three cycles of bortezomib 1.3 mg/m2 , were administered. Despite rescue therapy with eculizumab, necrosis of the lips and the perioral area occurred, which led to surgical removal of the lower lip, labial commissures, and part of the right cheek in May 2015. In January 2016, the patient underwent conventional facial reconstruction because during the retransplantation evaluation a small-cell lung carcinoma was discovered, causing the patient's death in April 2016.

RESUMO

BACKGROUND: Mycophenolate mofetil (MMF) is an effective immunosuppressive agent that has been frequently used in laboratory animals including swine; however, the pharmacokinetic properties of MMF in swine have not been studied. This short-term study was designed to evaluate the feasibility and the pharmacokinetic profiles of MMF therapy in neonatal swine. MATERIALS AND METHODS: Twelve neonatal pigs were randomized into four groups including one control and three treated groups with oral MMF administered at 0.5, 1, and 2 g/m(2)/d for 4 days, divided by 2 half-doses at 9:00 and 17:00 (except day 4 during which MMF was not administered at 17:00). Blood samples were collected at 9:00 on days 0, 2, 3 and 4 for complete blood count and hepatic/renal function examination; the trough concentration of plasma mycophenolic acid (MPA) was also determined. On days 2 and 4, blood was collected to determine the area under the curve (AUC) of plasma MPA concentration. Animal body-weight growth and manifestations of MMF side-effects such as anorexia, vomiting, and diarrhea were also observed. RESULTS: MMF has no acute hepatic/renal toxicity in newborn pigs; however, less body-weight growth was observed in treated groups. In the control group, a spontaneous increase of lymphocyte count was observed; in contrast, MMF therapy with doses of 1 and 2 g/m(2)/d reduced both lymphocyte and monocyte counts of piglets. Oral MMF had high bioavailability in neonatal swine. MPA-AUC0-12h of doses 0.5, 1, and 2 g/m(2)/d was 22.00 ± 3.32, 57.57 ± 34.30, and 140.00 ± 19.70 µg × h/mL, respectively. Neither MPA trough concentration (MPA-C0), nor MPA maximum concentration (MPA-Cmax) or MPA-AUC0-6h had high correlation with MMF-dose. For surveillance of MPA exposure, MPA-C0 had significant correlation with MPA-AUC0-12h (Spearman's ρ = 0.933, AUC0-12h = 17.882 × C0 + 14.479, r(2) = 0.966). CONCLUSION: To reach adequate drug exposure and to reduce dose-dependent side effects, an MMF dose of 1 g/m(2)/d is recommended to be used as an initial dose for immunosuppressive therapy in piglets, and MPA-C0 monitoring is the most practical strategy for experimental transplantation study.

RESUMO

Composite tissue allotransplantations (CTAs) have clinically shown little, if any, evidence of chronic rejection. Consequently, the effect of chronic rejection on bones, joints, nerves, muscles, tendons and vessels may still have undescribed implications. We thoroughly assessed all allograft structures by histology, magnetic resonance imaging, ultrasonography and high resolution peripheral quantitative computed tomography scan in four bilateral hand-grafted patients (10, 7, 3 and 2 years of follow-up, respectively) and in one facial allotransplantation (5 years of follow-up). All the recipients presented normal skin structure without dermal fibrosis. Vessels were patent, without thrombosis, stenosis or intimal hyperplasia. Tendons and nerves were also normal; muscles showed some changes, such as a variable degree of muscular hypotrophy, particularly of intrinsic muscles, accompanied by fatty degeneration that might be related to denervation. In the majority of hand-grafted patients graft radius and recipient tibia showed a decrease in trabecular density, although in the graft radius the alterations also involved the cortices. No deterioration of graft function was noted. In these cases of CTA no signs of chronic graft rejection have been detected. However, the possibility that chronic rejection may develop in CTA exists, highlighting the necessity of close continuous follow-up of the patients.

RESUMO

Is innovation breaking of the way of thinking, breaker of taboos, concretisation of chimeras or simple benefit of an ineluctable evolution? The surgical act should be considered as innovation itself? From the first facial allotransplantation, innovation is declined in various ways, which could constitute the different answers regarding the planning and management to prepare such surgery, the realisation of the transplantation and also the multiple developments in terms of science and medicine. It is exactly in that meaning that could be really mentioned the term archetypal.

RESUMO

Hand allograft is a method in the stage of clinical experimentation, which is reserved in France for the treatment of bilateral traumatic amputees. This study reports the Lyon team experience, which is pioneer in this domain. Four patients (3 males and 1 female) underwent seven (one unilateral and three bilateral) hand transplantations from September 1998 to February 2007. The level of amputation was at the wrist or at the mid-forearm. Delay since hand loss ranged from 2.5 to 9 years. The surgical protocol was elaborated and planned case by case. All recipients received the same immunosuppressive treatment. Episodes of acute rejection were observed in the first 3 months after transplantation, which were easily managed after a few days increasing oral prednisone doses and applying topical immunosuppressants. Currently the patients receive the doses of immunosuppressants comparable to those in kidney-grafted patients. We have not registered any severe complication of immunosuppressive treatment up till now (7 years follow-up for the earliest graft). We performed analytical and functional clinical, as well as questionnaire evaluation of patients. The first case (unilateral graft) resulted in graft failure at 2 years due to non-compliance of the patient. The three bilateral graftees demonstrate a favorable evolution despite some immunological (hyperglycemia, serum sickness) and surgical (thrombosis, osteomyelitis, skin loss) complications, which could be managed. The middle and long-term follow-up evaluation revealed good to excellent sensorimotor recovery of 4 hands in both male recipients (4 and 7 years) with satisfactory social adaptation, higher or equal to those expected after post-traumatic replantations at the equivalent level and higher to those obtained with currently available myoelectric prosthesis. The last patient, a young female who has been grafted in February 2007, receives ongoing reeducation course and shows normal progress of functional restoration of both hands. The encouraging results of this clinical experimentation make us currently consider hand allografting as reasonable and useful both for the patients and for evolution of research in composite tissues allotransplantation (CTA). Further long-term careful research and worldwide monitoring of all patients with hand allografts is required to, on the one part, state on the authorization of this surgery, and, on the other part, to better elucidate the mechanisms of successful CTA.

RESUMO

Mediatisation of a scientific event could be neither controlled, nor verifiable. The experience which has been lived through the first worldwide allotransplantation of composite tissues of the face confirms that the actors of a surgical innovation are not the owners. Because there is neither confidentiality nor possible patent. Curiously the scientific world, providing with a sharing ethic, which rightly privileges the free spreading of knowledge in the way that most people could benefit of it. Obviously it is made without denied controversy, for truth as purpose. This scientific word that way joins the media one, with a specific ethic of the duty of information, but also interested in mercantile preoccupations quick to cultivate controversy not to enlighten this truth but to better sell pictures or papers. Than the author should only sustain this instrumentation which could certainly flatter him, and from which he could used, but in reality that paralysed him a little to go on in serenity with his shadow worker way.

RESUMO

The first facial allograft was realised in Amiens 2005 November 27th. Breaking the technical limits of the so called possible and in appearance transgressing some cultural forbidden in organ transplantation, this resolutely innovative intervention open more than new perspective in the surgery of the reconstruction after disfigurement, but also a wide field of scientific investigations about dynamic and meaning of the facial function. Obviously, it also deals with numerous ethical and medical problems. The authors here shortly described the technical points of the surgery firstly done to restore oral function and facial expressively, the principles of the immunosuppressive treatment built to control any rejection time episode and the anatomical, neurological and functional results obtained after more than 18 months follow-up. Those perfectly demonstrate the perfect morphological, dynamic and cortical integration of the graft in the recomposed face. They also allow to confirm the legitimacy of the surgical indication and to oppose the factual objective arguments to the ethical reticences dealing with the facial and psychological identity of the receptor.

RESUMO

The first successful human hand transplantation, performed on September 1998, has translated the scope of 'composite tissue allotransplantation' from research concepts into clinical practice. Beyond microsurgical problems that have been overcome several years ago, the main obstacle that still prevents the generalization of composite tissue allotransplantation is immunologic. This review, which summarizes the evidence obtained both from experimental animal models and from the first recipients of a hand transplant, is focused on the two immunological characteristics of composite allografts that set them apart from other solid organ allografts: (i) they contain skin tissue that elicits a strong immune response; and (ii) they contain lymphoid tissues (such as bone marrow and lymph nodes) that have the potential both to attack the recipient, and also to down-modulate the host immune response and induce tolerance. While on one hand, the composite tissue allografts raise new challenges to transplant immunologists, on the other they provide answers to questions that have remained unresolved for a long time. In this sense, composite tissue allografts extend a helping hand to transplant immunologists.

RESUMO

In this study we present our experience concerning bilateral hand transplantation. Two cases were performed: the first in January 2000 and the second in April 2003. Both recipients received the same immunosuppressive treatment, which was similar to those used in solid organ transplantation, including tacrolimus, prednisone and mycophenolate mofetil while antithymocyte globulins were added for induction. Both recipients presented two episodes of acute rejection (maculopapular lesions) in the first 3 months after transplantation; however, these were easily reversed after a few days increasing oral steroid doses and using topical immunosuppressants. The first recipient presented hyperglycemia and serum sickness while the second recipient suffered a thrombosis of the right ulnar artery and an osteomyelitis of left ulna. All the complications were successfully treated. Functional Magnetic Resonance Imaging (fMRI) showed that cortical hand representation progressively shifted from the lateral to the medial region in the motor cortex. After 6 and 2 years respectively, they showed a relevant sensorimotor recovery particularly of sensibility and activity of intrinsic muscles. They were able to perform the majority of daily activities and to lead a normal social life. The first recipient has been working since 2003. They are both satisfied with their grafted hands.

RESUMO

Composite tissue allograft has become a clinical reality: hands, vascularized femoral diaphyses, abdominal walls, a larynx have all been transplanted throughout the world. Conventional immunosuppressive protocol has shown to be sufficient and effective. Rejection has been prevented in most cases and when it did occur it was successfully reversed. Skin has been confirmed as the principal target of acute and chronic rejection. There has been no mortality or early graft losses and, particularly in hand transplantation, the survival graft rate is 91% with a follow-up period ranging from 6 months to 61 months. The side effects of immunosuppression are limited and include primarily transient hyperglycemia, an increase in creatinine values and some opportunistic infections (i.e. cytomegalovirus infection). Nerve regeneration and cortical reorganization have been demonstrated in hand transplantation. Functional results have been encouraging particularly for hand and larynx transplantation. Appropriate indications and patient selection, based particularly on patient motivation and compliance, are essential requirements for composite tissue allograft success.

RESUMO

Hand transplantation may become an important procedure for upper limb functional restoration. To date, 18 patients have been undergone 24 hand operations in the world. Initial results are extremely promising; the functional results are apparently superior to those obtained with prostheses. We report on the combined French and Italian experience of six patients (eight hands), which is based on a jointly devised protocol and represents the largest available clinical series. Six male patients aged 43, 33, 35, 32, 33, and 22 years received either a single right hand-dominant transplantation (four cases) or a simultaneous double hand transplantation (two cases). The time since the amputation ranged from 3 to 22 years. The level of transplantation was at the wrist in five cases (six hands) and at the distal forearm in two cases (two hands). Cold ischemia averaged 11.5 hours. Three patients simultaneously received additional full-thickness skin taken from the donor and transplanted onto their left hip area. This skin served as a source for biopsies and as an additional area to monitor rejection (distant sentinel skin graft). The immunosuppressive protocol included polyclonal antibodies (three patients) or monoclonal anti-CD 25 antibody (three patients), tacrolimus, mycophenolate mofetil, and prednisolone. No surgical complications occurred. Skin rejection occurred at least once in all patients at a mean of 40 days postoperatively. Three patients recovered protective and some discriminative sensation in their palm and fingers. Two patients are recovering sensation, but are still in the early phases of the regenerative process, due to the short time since the transplantation. One patient was not compliant with the immunosuppressive therapy, and underwent uncontrolled rejection and reamputation.

RESUMO

Cystic lymphangioma of the adrenal gland are rarely encountered tumoural formations with no clinical expression. Pre-operative diagnosis is difficult. Echography and CT scan are essential exploratory techniques, diagnosis is histological. Usually surgical exploration is indicated due to uncertain diagnosis. We report a new case of cystic lymphangioma of the adrenal gland and a review of recent literature.

RESUMO

OBJECTIVE: To report results of a clinical investigation on the detection of bladder dysplasia and in situ carcinoma by using fluorescence induced by 5-aminolaevulinic acid (ALA). PATIENTS AND METHODS: The study included 50 patients with a primary bladder lesion, who had a bladder instillation of 50 mL of 3% ALA solution >or= 1 h before transurethral resection of the tumour. Random biopsies were taken using white-light cystoscopy, then using blue light to induce fluorescence; positive zones were noted and biopsied. The primary lesion was then resected. The frequency of dysplasia detected by ALA-induced fluorescence was evaluated, as was the risk of recurrence with a follow-up of >or= 2 years. RESULTS: In all patients the tumours were positive; in 21 fluorescence distant from the tumour was detected. The pathological report of the biopsies showed 11 cases of dysplasia, six of carcinoma in situ and four of inflammatory lesions. In 29 patients there was no fluorescence and quadrant biopsies were normal in all but three with moderate dysplasia. Within the minimum follow-up patients with bladder dysplasia detected by ALA-induced fluorescence had a higher risk of recurrence. CONCLUSION: ALA-induced fluorescence of the bladder significantly enhanced the detection of dysplasia and in situ carcinoma. However, this technique requires further investigation using well-characterized instrumentation and study protocols to determine any effect on treatment choice.

RESUMO

AIM OF THE STUDY: The previous results achieved in single hand transplantations confirmed the feasibility of this procedure and encouraged us to perform the first human double hand transplantation, which was performed in January 2000. In the present study we reported the results obtained eighteen months after transplantation. PATIENT AND METHODS: The recipient was a 33-year old man suffering from a traumatic amputation of both hands in 1996. Surgery included procurement of the upper extremities from a 18-year old multiorgan cadaveric donor, preparation of the graft and recipient's stumps, transplantation of the hands, which included bone fixation, arterial and venous anastomoses, nerve suture, joining of tendons and muscles, and skin closure. Immunosuppressive protocol included tacrolimus, prednisone and mycophenolate mofetil. An intensive rehabilitation program was performed. Follow-up included immunological tests, skin biopsies, arteriography, bone scintigraphy, electromyography and brain functional magnetic resonance imaging. RESULTS: No surgical complications, infectious complications and graft-versus-host-disease occurred. Two episodes of acute skin rejection were demonstrated and they were completely reversed increasing steroid dose. Nerve regeneration and cortical reorganization were shown. Sensorimotor recovery was encouraging and life quality improved. CONCLUSION: This double hand transplantation showed that conventional immunosuppressive protocol is effective and safe as well as that functional results are at least as good as those achieved in replanted upper extremities.
