Rev Bras Ortop 2022; 57:207-213. [PMID: 35652029 PMCID: PMC9142254 DOI: 10.1055/s-0041-1736467] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2021] [Accepted: 04/12/2021] [Indexed: 11/25/2022] Open
Abstract
Peripheral nerve damage is an important cause of seeking medical attention. It occurs when the continuity of structures is interrupted and the propagation of nervous impulses is blocked, affecting the functional capacity of individuals. To assess the effects of the immunosuppressants tacrolimus and cyclosporine on the regeneration of peripheral nerves, a systematic review of the literature was carried out. The articles included were published until September 2018 and proposed to evaluate the effects of the immunosuppressants tacrolimus and cyclosporine on nerve regeneration and neuroprotection, available in the MEDLINE, EMBASE, Cochrane Library, Web of Science, Oxford Pain Relief Database, and LILACS databases. The research analysed a total of 56 articles, of which 22 were included in the meta-analysis. Statistical analysis suggests the protective effect of tacrolimus in the regeneration of the number of myelinated axons (95% confidence interval [CI]: 0.93–2.39;
p
< 0.01); however, such effect was not observed in relation to cyclosporine (95%CI: - 0.38–1.18;
p
= 0.08) It also suggests that there is a significant relationship between the use of tacrolimus and myelin thickness (95%CI= 2.00–5.71;
p
< 0. 01). The use of immunosuppressants in the regeneration of peripheral nerve damage promotes an increase in the number of myelinated axons in general, regardless of the administered dose. In addition, it ensures greater myelin thickness, muscle weight and recovery of the sciatic functional index. However, heterogeneity was high in most analyses performed.

Abstract
Peripheral nerve regeneration is a unique process in which cellular rather than tissue response is involved. Depending on the extent and proximity of the lesion and the age and type of the neuronal soma, the cell body may either initiate a reparative response or may die. Microsurgical intervention may alter the prognosis after a peripheral nerve injury but to a certain extent. By altering the biochemical microenvironment of the neuron, we can increase the proportion of neurons that survive the injury and initiate the reparative response.
Thyroid hormone critically regulates tissue growth and differentiation and plays a
crucial role during organ development. Furthermore, recent research has provided
new insight into thyroid hormone cellular action. Thyroid hormone regulates stress
response intracellular signaling and targets molecules important for cytoskeletal
stability and cell integrity. Changes in thyroid hormone signaling occur in nerve and
other tissues, with important physiological consequences. The interest in thyroid
hormone in the context of nerve regeneration has recently been revived.

Abstract
This chapter provides a review of immune reactions involved in classic as well as alternative methods of peripheral nerve regeneration, and mainly with a view to understanding their beneficial effects. Axonal degeneration distal to nerve damage triggers a cascade of inflammatory events alongside injured nerve fibers known as Wallerian degeneration (WD). The early inflammatory reactions of WD comprise the complement system, arachidonic acid metabolites, and inflammatory mediators that are related to myelin fragmentation and activation of Schwann cells. Fine-tuned upregulation of the cytokine/chemokine network by Schwann cells activates resident and hematogenous macrophages to complete the clearance of axonal and myelin debris and stimulate regrowth of axonal sprouts. In addition to local effects, immune reactions of neuronal bodies and glial cells are also implicated in the survival and conditioning of neurons to regenerate severed nerves. Understanding of the cellular and molecular interactions between the immune system and peripheral nerve injury opens new possibilities for targeting inflammatory mediators to improve functional reinnervation.

Abstract
Objectives: The risks of daily immunosuppression limit the use of laryngeal transplantation as a reconstructive option. Pulsed immunosuppressive dosing can lessen these risks. The study objective was to develop a long-term pulsing regimen that minimizes exposure to immunosuppressive agents. Methods: Rat laryngeal transplantation was performed. Everolimus (1 mg/kg per day) and anti–αβ T-cell receptor (TCR) antibodies (250 μg) were given for 7 days beginning 1 day before transplantation and for 5 days beginning on day 90 after transplantation. On day 180, group 1 (n = 5) received the initial regimen for 3 days, and group 2 (n = 5) received everolimus (1 mg/kg per day) until euthanization, which occurred when parathyroid hormone (PTH) levels dropped to less than 11 pg/mL or at 300 days. Results: Four of the 5 rats in group 1 had normal PTH levels at 300 days. The PTH level for 1 rat was less than 11 pg/mL at 270 days. In group 2, none of the 5 rats had normal PTH levels at 300 days. Two had PTH levels below 11 pg/mL at 270 days, and 3 had PTH levels below 11 pg/mL at 300 days. The allografts that survived beyond 300 days had an essentially normal histologic appearance. Conclusions: Pulsed immunosuppression prevented allograft rejection for 10 months and was more effective than daily everolimus. Short-term perioperative therapy followed by pulsed, tapered dosing is a viable alternative to traditional regimens and may decrease associated risks.

Abstract
T10B9.1A-31/MEDI-500 is a nonmitogenic immunoglobulin M kappa murine monoclonal antibody (mAb) directed against the alpha-beta (αβ) heterodimer of the T-lymphocyte receptor complex. The hybridoma was first produced by fusing spleen cells from BALB/C mice immunized with human peripheral blood T-lymphocytes with SP2/O-Ag14 mutant myeloma cells. The mAb is produced and purified using multistep ion exchange and molecular sieve chromatography protocols. T10B9 has been used successfully to treat acute cellular rejection in renal transplantation and as an immunosuppression induction agent in heart and simultaneous kidney-pancreas transplantation. Because T10B9 is nonmitogenic and causes minimal cytokine release, both treatment of rejection and induction of immunosuppression were accomplished with significantly fewer and milder untoward effects (cytokine release syndrome) than its comparator OKT3. Since T10B9 is directed against the αβ heterodimer of the CD3 epitope, it spares the gamma delta (γδ) region. These gamma delta (γδ) T cells have a unique role in the immune response controlling many serious human diseases and perhaps facilitating the development of immunologic tolerance. T10B9 has a relatively short duration of action, depleting T cells for only 10 to 14 days, unlike the protracted depletion seen with thymoglobulin and Campath-1H. There is no B-lymphocyte depletion with T10B9 as there is with both of the aforementioned reagents. The lack of prolonged lymphocyte depletion may account for less infection observed with T10B9 treatment.

Abstract
Despite the progress in understanding the pathophysiology of peripheral nervous system injury and regeneration, as well as advancements in microsurgical techniques, peripheral nerve injuries are still a major challenge for reconstructive surgeons. Thorough knowledge of anatomy, pathophysiology, and surgical reconstruction is a prerequisite of proper peripheral nerve injury management. This chapter reviews the currently available surgical treatment options for different types of nerve injuries in clinical conditions. In overview of direct nerve repair, various end-to-end coaptation techniques and the role of end-to-side repair for proximal nerve injuries is described. When primary repair cannot be performed without undue tension, nerve grafting or tubulization techniques are required. Current gold standard for bridging nerve gaps is nerve autografting. However, disadvantages of this approach, such as donor site morbidity and limited length of available graft material encouraged the search for alternative means of nerve gap reconstruction. Nerve allografting was introduced for repair of extensive nerve injuries. Tubulization techniques with natural or artificial conduits are applicable as an alternative for bridging short nerve defects without the morbidities associated with harvesting of autologous nerve grafts. Achieving better outcomes depends both on the advancements in microsurgical techniques and introduction of molecular biology discoveries into clinical practice. The field of peripheral nerve research is dynamically developing and concentrates on more sophisticated approaches tested at the basic science level. Future directions in peripheral nerve reconstruction including, tolerance induction and minimal immunosuppression for nerve allografting, cell based supportive therapies and bioengineering of nerve conduits are also reviewed in this chapter.

Abstract
A enxertia alógena de nervo teve seu interesse renovado após o desenvolvimento de melhores drogas imunossupressoras. Neste trabalho estudou-se a enxertia alógena de nervo utilizando a técnica de planimetria por contagem de pontos.Foram considerados três grupos: Grupo A - ratos Lewis que receberam enxertos de nervo de doadores isogênicos; Grupo B - ratos Lewis que receberam enxertos de nervo de ratos doadores Brown-Norway e foram tratados com solução salina; Grupo C - ratos Lewis que receberam enxertos de nervo de ratos doadores Brown-Norway e foram tratados com ciclosporina. A regeneração neural foi avaliada por análise histológica e estudos histomorfométricos depois de 6 e 12 semanas. Com 6 semanas, a densidade de fibras neurais e a porcentagem de tecido neural no grupo de enxertos alógenos com imunossupressão (grupo C) era significativamente mais alta do que no grupo B. Os grupos de enxertos alógenos (grupo B e C) mostraram densidade menor de fibras de nervo e porcentagem de tecido neural que no grupo de enxerto autógeno (grupo A) tanto com 6 quanto com 12 semanas.O método de planimetria por contagem de pontos produziu resultados precisos e reprodutíveis.

Abstract
Nerve allograft transplantation should be used for the repair of devastating peripheral nerve injuries that cannot be reconstructed through traditional means such as autologous nerve grafting or nerve transfer procedures. The risks of required systemic immunosuppression, although only temporary for nerve allograft recipients, preclude widespread use of this treatment modality. Translational research has led to several advancements in this field including the use of preoperative allograft cold preservation in University of Wisconsin organ preservation solution and inclusion of tacrolimus as part of the immunosuppressive regimen. Investigation of how to further diminish nerve allograft immunogenicity, speed neuroregeneration by use of agents such as tacrolimus, and promote preferential motor regeneration will further advance this field with the goal of restoring optimal function while minimizing patient morbidity.
