Maggot Debridement Therapy

  • 文章类型: Journal Article
    难以愈合的伤口的管理仍然是医疗保健系统的重大挑战,沉重的经济负担。Maggot清创疗法,使用的是丝叶夜蛾的无菌幼虫,有效清除坏死组织,促进愈合,但它的使用是有限的。这篇叙述性综述考察了注册护士使用这种清创形式的影响,专注于知识和态度,治疗相关疼痛,和实际问题。研究结果表明,与非伤口专家相比,伤口专科护士更了解和支持the清创治疗。强调需要有针对性的教育干预。疼痛管理至关重要,关于疼痛程度的报道好坏参半,强调量身定制的疼痛缓解策略的必要性。实际挑战包括采购困难和成本,建议需要简化流程和明确的临床指南。通过教育解决这些障碍,研究,和改进的物流可以提高对the的接受和使用清创疗法,改善患者伤口管理的结果。
    Management of hard-to-heal wounds remains a significant challenge for healthcare systems, with substantial economic burdens. Maggot debridement therapy, using sterile larvae of Lucilia sericata, effectively debrides necrotic tissue and promotes healing, yet its use is limited. This narrative review examines the influences on the use of this form of debridement by registered nurses, focusing on knowledge and attitudes, treatment-related pain, and practical issues. Findings indicate that wound specialist nurses are more knowledgeable and supportive of maggot debridement therapy compared with non-wound specialists, underscoring the need for targeted educational interventions. Pain management is critical, with mixed reports on pain levels, highlighting the necessity for tailored pain-relief strategies. Practical challenges include procurement difficulties and cost, suggesting a need for streamlined processes and clear clinical guidelines. Addressing these barriers through education, research, and improved logistics could enhance the acceptance and use of maggot debridement therapy, improving patient outcomes in wound management.

    从业者和科学家正在重新研究边缘化的伤口护理疗法,以找到在不影响患者预后的情况下应对日益增长的抗菌素耐药性(AMR)问题的策略。Maggot疗法(MT)仅占英国国家卫生服务在伤口护理方面支出的0.02%。这项研究旨在揭示为什么MT不经常使用,尽管它的负担能力和高水平的清创和消毒功效,特别是在AMR感染的情况下,并确定可以采取哪些措施来确保将来更有效地使用MT来改善患者预后并管理日益严重的AMR问题。
    对于这项调查,我们采用系统评价和Meta分析的首选报告项目框架,对使用MT抗AMR感染的病例研究进行了定性评价,并对随机对照试验(RCT)进行了定量分析.
    分析表明,MT对一系列感染和伤口类型非常有效,与传统疗法相比,效果很好。MT使用率低的部分原因可能是由于记录的“恶心因素”,通常与got以及对成本的误解有关,MT的功效和可及性。为了克服这些因素,需要更多关于MT在各种临床表现中的频谱和疗效的随机对照试验,以及专业和公众参与活动。
    MT是一种未充分利用的疗法,特别是关于AMR感染,在这种情况下扩大其使用似乎是有道理的。MT可以在保护现有抗菌药物库的功效方面发挥至关重要的作用,应在制定抗菌药物管理计划时予以考虑。

    UNASSIGNED: Practitioners and scientists are re-examining marginalised wound care therapies to find strategies that combat the growing problem of antimicrobial resistance (AMR) without compromising patient outcomes. Maggot therapy (MT) makes up just an estimated 0.02% of UK\'s National Health Service spending on wound care. This study aims to uncover why MT is not used more often, despite its affordability and high level of efficacy for both debridement and disinfection, particularly in the context of AMR infections, and to determine what can be done to ensure MT is more effectively used in the future to improve patient outcomes and manage the growing problem of AMR.
    UNASSIGNED: For this investigation, a qualitative review of case studies using MT against AMR infections and a quantitative analysis of randomised control trials (RCTs) were performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses framework.
    UNASSIGNED: Analysis showed that MT is highly effective against a range of infections and wound types, and compares well against conventional therapies. The low use of MT may be due in part to the documented \'yuck factor\', often associated with maggots as well as misconceptions around the cost, efficacy and accessibility of MT. To overcome these factors, more RCTs on the spectrum and efficacy of MT across various clinical manifestations are needed, as well as professional and public engagement campaigns.
    UNASSIGNED: MT is an underused therapy, particularly regarding AMR infections, and expanding its use in these circumstances appears warranted. MT could play a vital role in conserving the efficacy of the existing pool of antimicrobials available and should be considered in the development of antimicrobial stewardship programmes.

    方法:描述性,横断面研究。
    方法:样本包括60名参与者,60%为男性(n=36)。他们的平均年龄为62.9(SD=20)岁。几乎一半的参与者有下肢伤口(n=26;43.3%),糖尿病足溃疡(n=18;30%),和压力伤害(n=9;15%)。大多数人通过生物袋接受the治疗(n=36;60%)。
    方法:参与者填写了为研究目的而设计的问卷,该问卷查询了人口统计学和相关的临床特征,当前的健康状况,包括当前的局部治疗,和他们慢性伤口的持续时间。在MDT之前,有九个项目查询了情绪反应,虫疗法的数量和方法,在治疗期间经历的不适,以及有关这种治疗的信息来源。
    结果:开始MDT之前的情绪反应包括厌恶(n=30,50%),焦虑(n=26,43.3%),对其有效性的怀疑(n=20,33.3%),和怀疑(n=11,18.3%)。大约三分之一的参与者报告有咬人的感觉,瘙痒,和对the的恐惧。尽管有这些感觉,大多数(n=38,63.3%)表示他们对治疗结果感到满意,并愿意在需要时接受额外的MDT.
    结论:虽然大多数慢性伤口愈合的参与者报告了与MDT相关的负面情绪,超过一半的人表示他们对治疗结果感到满意,并愿意接受重复治疗.
    OBJECTIVE: The purpose of this study was to describe patient experiences and satisfaction with use of maggot debridement therapy (MDT) for hard-to-heal wounds.
    METHODS: Descriptive, cross-sectional study.
    METHODS: The sample comprised 60 participants, 60% were male (n = 36). Their mean age was 62.9 (SD = 20) years. Almost half of participants had lower extremity wounds (n = 26; 43.3%), diabetic foot ulcers (n = 18; 30%), and pressure injuries (n = 9; 15%). Most received maggot therapy via biobags (n = 36; 60%).
    METHODS: Participants completed a questionnaire designed for purposes of the study that queried demographic and pertinent clinical characteristics, current health status including current topical therapies, and duration of their chronic wound. Nine items queried emotional responses prior to MDT, the amount and method of the maggot therapy, discomfort experienced during therapy, and sources of information regarding this treatment.
    RESULTS: Emotional responses before starting MDT included disgust (n = 30, 50%), anxiety (n = 26, 43.3%), doubts about its effectiveness (n =20, 33.3%), and disbelief (n = 11, 18.3%). Approximately one-third of participants reported feelings of biting, itching, and fear of the maggots. Despite these feelings, a majority (n = 38, 63.3%) indicated that they were pleased with treatment outcome and willing to undergo additional MDT if needed.
    CONCLUSIONS: While a majority of participants with nonhealing chronic wounds reported negative emotions association with MDT, more than half indicated that they were pleased with the outcome of treatment and willing to undergo repeat treatment if indicated.

    大约13%的糖尿病患者在疾病过程中会出现一种或多种溃疡,糖尿病足溃疡(DFU)占全世界下肢截肢的60%以上。此病例系列旨在证明DFU上的医用got在促进伤口愈合和减少尼日利亚北部相关住院时间方面的有效性。
    在2021年1月至8月期间在阿米努·卡诺教学医院(AKTH)的骨科病房,对同意这种治疗的患者的DFU进行了Maggot清创治疗(MDT)。卡诺,尼日利亚。sericata的无菌第一龄幼虫是本地获得的,并在无菌程序下使用限制(自由范围)方法应用。
    共有15例DFU为Wagner分类III级(33.3%)和IV级(66.7%)的患者,被看到并记录在案。患者包括10名(66.7%)女性和5名(33.3%)男性,给出2:1的女性:男性比例。受访者的平均年龄(±标准差)为51.6±10.8岁。伤口的表面积为24-140cm2,中值为75cm2。在患者中,60%有两个周期的MDT,中位持续时间为5天。大多数伤口(53.3%)在五天内清创;13.3%(两个伤口)需要7天才能完全清创。配对样本t检验显示伤口表面积与治疗持续时间(t=8.0;p=0.000)之间以及伤口表面积与治疗周期(t=8.3;p=0.000)之间的统计学显著关联。在申请之前,14个(93.3%)DFU完全(100%)被泥泥覆盖,只有一个(6.7%)被泥覆盖95%。在应用程序之后,10例(66.7%)伤口完全清创,而5例(33.3%)伤口需要床边手术清创才能实现完全清创。配对的样本t检验显示覆盖伤口的MDT前后的淤泥之间的统计学显著差异(t=45.1;p=0.000)。
    在这种情况下,MDT已成功用于DFU的清创,这促进了愈合过程,临床结果令人鼓舞。
    UNASSIGNED: Approximately 13% of people living with diabetes develop one or more ulcers during the course of the disease, and diabetic foot ulcer (DFU) is responsible for >60% of lower limb amputations worldwide. This case series aimed to demonstrate the effectiveness of medical-grade maggots on DFUs in promoting wound healing and reducing related hospital stays in northern Nigeria.
    UNASSIGNED: Maggot debridement therapy (MDT) was applied to the DFUs of patients who consented to this treatment between January-August 2021 at the Orthopaedic Unit of the Aminu Kano Teaching Hospital (AKTH), Kano, Nigeria. Sterile first instar larvae of Lucilia sericata were obtained indigenously and applied using the confinement (free-range) method under aseptic procedure.
    UNASSIGNED: A total of 15 patients with DFUs of Wagner classification grades III (33.3%) and IV (66.7%), were seen and documented. The patients included 10 (66.7%) females and five (33.3%) males, giving a female:male ratio of 2:1. The mean age (±standard deviation) of the respondents was 51.6±10.8 years. The surface area of the wounds ranged from 24-140cm2, with a median value of 75cm2. Among the patients, 60% had two cycles of MDT, with a median duration of five days. Most of the wounds (53.3%) were debrided within five days; 13.3% (two wounds) took seven days to be fully debrided. A paired sample t-test showed a statistically significant association between wound surface area and therapy duration (t=8.0; p=0.000) and between wound surface area and cycles of therapy (t=8.3; p=0.000). Before maggot application, 14 (93.3%) DFUs were completely (100%) covered with slough and only one (6.7%) was 95% covered with slough. After maggot application, 10 (66.7%) wounds were completely debrided while five (33.3%) wounds required bedside surgical debridement to achieve complete debridement. A paired sample t-test showed statistically significant difference between the pre- and post-MDT slough covering the wounds (t=45.1; p=0.000).
    UNASSIGNED: In this case series, MDT was successfully used in the debridement of DFUs, which facilitated the healing process with an encouraging clinical outcome.

    这项研究的目的是确定the清创疗法(MDT)在糖尿病足溃疡(DFU)愈合过程中对巨噬细胞的影响。使用双重染色免疫组织化学(IHC)评估MDT后伤口愈合期间巨噬细胞的活化表型。此外,使用免疫印迹和实时聚合酶链反应(PCR)发现了与巨噬细胞活化相关的标志物。在MDT后的糖尿病伤口愈合过程中,观察到M2巨噬细胞的存在和过表达,而M1巨噬细胞的表达不足。此外,巨噬细胞的活化标志物表现出与指定的Th1/Th2细胞因子的相关性。MDT干预有可能调节巨噬细胞活性,从而有助于糖尿病足伤口的愈合。
    The purpose of this study is to determine the impact of maggot debridement therapy (MDT) on macrophages during the healing process of diabetic foot ulcers (DFU). The activation phenotype of macrophages during wound healing following MDT was evaluated using double staining immunohistochemistry (IHC). In addition, markers associated with macrophage activation were discovered using immunoblotting and real-time polymerase chain reaction (PCR). During the process of diabetic wound healing following MDT, the presence and over-expression of M2 macrophages were observed, while the under-expression of M1 macrophages was noted. In addition, the activation markers of macrophages exhibited a correlation with the indicated Th1/Th2 cytokines. MDT interventions have the potential to modulate macrophage activity, thereby aiding in the healing of diabetic foot wounds.

    不断升级的抗菌素耐药性(AMR)危机需要创新的治疗策略。粪便微生物移植(FMT)和of清创疗法(MDT)代表了范式转变的方法,利用生物系统来减轻AMR。FMT恢复了健康的肠道微生物组,为致病菌提供生物治疗,从而减少对传统抗生素的依赖。相反,MDT,一种生物清创术,利用ago的抗菌分泌物清洁伤口并消除耐药细菌。尽管这些疗法有希望,他们更广泛的临床采用面临多方面的挑战,包括需要严格的科学证据,标准化协议,加深对行动机制的理解,并超越监管和公众接受障碍。然而,他们与精准医学的潜在整合可能会彻底改变疾病管理,特别是抗生素耐药感染。
    耐药感染的日益严重的问题需要新的治疗方法。粪便微生物移植(FMT)和of清创疗法(MDT)提供了创新的解决方案。FMT使用健康的肠道细菌来对抗有害的细菌,而MDT则使用the来清洁伤口并杀死抗性细菌。虽然很有希望,这些方法面临着缺乏理解等挑战,标准化和公众接受度。他们的潜力,然而,可以改变我们管理抗生素抗性疾病的方式。
    The escalating crisis of antimicrobial resistance (AMR) warrants innovative therapeutic strategies. Fecal microbiota transplantation (FMT) and maggot debridement therapy (MDT) represent paradigm-shifting approaches, leveraging biological systems to mitigate AMR. FMT restores a healthy gut microbiome, providing a biotherapeutic counter to pathogenic bacteria, thereby reducing reliance on traditional antibiotics. Conversely, MDT, a form of bio-debridement, utilizes the antimicrobial secretions of maggots to cleanse wounds and eliminate resistant bacteria. Despite the promise these therapies hold, their broader clinical adoption faces multifaceted challenges including the need for rigorous scientific substantiation, standardized protocols, deepened understanding of mechanisms of action, and surmounting regulatory and public acceptance barriers. However, their potential integration with precision medicine could revolutionize disease management, particularly with antibiotic-resistant infections.
    The rising problem of drug-resistant infections calls for new treatment methods. Fecal microbiota transplantation (FMT) and maggot debridement therapy (MDT) offer innovative solutions. FMT uses healthy gut bacteria to fight harmful ones, while MDT employs maggots to clean wounds and kill resistant bacteria. Although promising, these methods face challenges like a lack of understanding, standardization and public acceptance. Their potential, however, could transform how we manage antibiotic-resistant diseases.

    未经授权:Maggot清创疗法(MDT)是一种新兴的程序,涉及应用双翅目(通常是Luciliasericata)的无菌虫进行清创,消毒并促进对抗菌治疗无反应的伤口愈合。撒哈拉以南非洲(包括尼日利亚)的MDT数据很少。这项研究旨在使用药用级got作为补充方法来清除难以治愈的坏死性溃疡,从而促进伤口愈合。
    未经批准:在这项描述性研究中,我们报道了在AminuKano教学医院(AKTH)进行MDT的第一组患者,尼日利亚北部的一家三级医院。在无菌条件下,使用禁闭(自由放养)虫疗法敷料方法,应用了丝花夜蛾的第一龄幼虫。
    未经评估:糖尿病足溃疡(DFU)III-IV级占伤口的一半以上(53.3%),其次是坏死性筋膜炎(30%),创伤后伤口感染(10%)。其他(6.7%,包括化脓性肌炎,手术部位感染和创伤后伤口感染)。伤口的中值表面积为56cm2。在30名患者中,一半(50%)有两个MDT周期,中位时间为4天.在伤口中,22例(73%)仅使用the虫完全清创,而8例(27%)则实现了完全清创和手术清创。MDT前的伤口培养对所有患者均产生细菌生长,金黄色葡萄球菌在17个伤口中占主导地位(56.7%),而铜绿假单胞菌和化脓性链球菌在5个伤口中占主导地位(16.7%)。MDT后,只有四个(13.3%)伤口培养物产生细菌生长,所有金黄色葡萄球菌。
    未经证实:MDT后,各种伤口的预后良好。MDT可有效清创并显着消毒涉及不同解剖部位的伤口,从而促进伤口愈合和恢复。建议在此类伤口中使用MDT。
    UNASSIGNED: Maggot debridement therapy (MDT) is an emerging procedure involving the application of sterile maggots of the Dipteran species (commonly Lucilia sericata) to effect debridement, disinfection and promote healing in wounds not responding to antimicrobial therapy. Data on MDT in sub-Saharan Africa (including Nigeria) are scarce. This study aimed to use medicinal grade maggots as a complementary method to debride hard-to-heal necrotic ulcers and thereby promote wound healing.
    UNASSIGNED: In this descriptive study, we reported on the first group of patients who had MDT at Aminu Kano Teaching Hospital (AKTH), a tertiary hospital in northern Nigeria. The first instar larvae of Lucilia sericata were applied using the confinement (free-range) maggot therapy dressing method under aseptic conditions.
    UNASSIGNED: Diabetic foot ulcer (DFU) grade III-IV constituted more than half of the wounds (53.3%), followed by necrotising fasciitis (30%), and post-traumatic wound infection (10%). Others (6.7%, included pyomyositis, surgical site infection and post traumatic wound infection). The median surface area of the wounds was 56cm2. Of the 30 patients, half (50%) had two MDT cycles with a median time of four days. Of the wounds, 22 (73%) were completely debrided using maggots alone while eight (27%) achieved complete debridement together with surgical debridement. Wound culture pre-MDT yielded bacterial growth for all the patients and Staphylococcus aureus was the predominant isolate in 17 wounds (56.7%) while Pseudomonas aeruginosa and Streptococcus pyogenes were predominant in five wounds (16.7%) each. Only four (13.3%) wound cultures yielded bacterial growth after MDT, all Staphylococcus aureus.
    UNASSIGNED: A good prognosis was achieved post-MDT for various wounds. MDT effectively debrides and significantly disinfects wounds involving different anatomical sites, thus enhancing wound healing and recovery. MDT is recommended in such wounds.

    研究背景糖尿病足溃疡(DFU)是糖尿病的严重影响。本研究旨在通过miRNA芯片研究发现微核糖核酸(miRNA)在治疗the清创治疗(MDT)涉及的DFU中的作用。采取miRNA芯片办法。患有至少一个足部溃疡(当前或先前)的糖尿病(1型或2型)患者被纳入研究。测量用MDT治疗期间肉芽组织中miRNA表达的改变。在MDT之后,miR17-92的表达在体内得到证实。miR-17-3p表达增加,在接受MDT的DFU患者中,Flk-1(血管内皮生长因子)表达显着降低(P<0.01)。分泌或分泌的人脐静脉内皮细胞的结果与体外结果一致(P<0.001,P<0.05)。miR-17-3p的过表达显示对管形成的抑制活性(P<0.05)。当DFU用MDT治疗时,结果显示miR-17-3p对Flk-1有负调节作用.
    Background of the Study Diabetic foot ulcers (DFUs) are severe effect of diabetes. This research aimed to discover the role of micro-ribonucleic acid (miRNA) in treating DFUs involved in maggot debridement therapy (MDT) via a miRNA chip study. A miRNA chip approach was adopted. Patients with diabetes (type 1 or 2) who had at least one-foot ulcer (current or previous) were enrolled in the study. The alterations of miRNA expressions in the granulation tissue during treatment with MDT were measured. Following MDT, the increased expression of miR17-92 was verified in vivo. The miR-17-3p expression increased, and Flk-1 (vascular endothelial growth factor) expression was significantly reduced in patients with DFUs who received MDT (P < 0.01). Results from human umbilical vein endothelial cells that excrete or secrete showed consistency with in vitro findings (P < 0.001, P < 0.05). The overexpression of miR-17-3p demonstrated inhibitory activity on tube formation (P < 0.05). When DFUs were treated with MDT, it revealed that miR-17-3p had a negative regulatory effect on Flk-1.

    由于身体部位腐烂,伤口中幼虫的视觉和气味可能会在敏感个体中引起负面的视觉和嗅觉印象,腐肉,和痛苦。然而,Maggot清创疗法(MDT)非常有效,安全,对患者和卫生系统来说,伤口愈合和组织振兴都很便宜。该研究的目的是评估一组合格的护士进行MDT的准备情况,这些护士对接受慢性伤口治疗的患者进行治疗程序。使用了诊断调查。研究工具是一个由三个问卷组成的科学研究方案(社会人口统计,MDT感知问卷,用于视觉评估的伤口图片)。该研究包括290名护士;平均年龄超过42.6±9.9岁,中位数是44岁。在测试样品中实施该方法的感知和准备处于平均(标准)水平。伤口中the的图像引起医务人员的负面情绪。MDT方法的知识越高,在实践中实施的动力就越大。
    The sight and smell of larvae in the wound may cause negative visual and olfactory impressions in sensitive individuals because of decaying body parts, carrion, and suffering. However, Maggot Debridement Therapy (MDT) is highly effective, safe, and cheap in wound healing and tissue revitalization for both the patient and health systems. The aim of the study was to assess the readiness to undertake MDT in a group of qualified nurses who perform therapeutic procedures in patients treated for chronic wounds. A diagnostic survey was used. The research tool was a scientific research protocol consisting of three questionnaires (sociodemographics, MDT perception questionnaire, pictures of wounds for visual assessment). The study included 290 nurses; the mean age was over 42.6 ± 9.9 years, and the median was 44 years. The perception and readiness to implement the method in the tested sample is at the average (standard) level. The image of maggots in the wound causes negative emotions among medical personnel. The higher the knowledge of the MDT method, the greater the motivation to implement it in practice.
