Normally, these four waves in the healing process progress quickly and smoothly, one into the next. 1, pp. When no longer needed, the cells undergo apoptosis and are removed or engulfed by other cells (i.e., macrophages). 3, pp. The most noticeable change in maggot-treated wounds is debridement: the dead (necrotic or gangrenous), infected tissues and debris are removed from the wound, and the wound bed is left looking clean and healthy. The indications for that product were limited to debridement. 6, pp. 2, pp. Effective debridement occurred with a maximum of 1 larval application in all 6 experimental patients; 2 of the 6 hydrogel patients still required dressings at 1 month. 119–125, 2009.

Early clinical reports of maggot-induced wound healing were merely case studies or series; but beginning in the 1990’s, controlled comparative trials of maggot therapy began to appear. J. W. Costerton, P. S. Stewart, and E. P. Greenberg, “Bacterial biofilms: a common cause of persistent infections,” Science, vol. Of the three described actions of maggot therapy, debridement (physical and chemical) is the best studied. Today maggots' therapy became less treatment of last resort but of first choice in leg ulcers, carbuncules, pressure ulcers and infected traumatic wounds. A. Zhang and colleagues 69) are currently seeing evidence that maggot extracts may even stimulate the growth of neural tissue. 7, pp. L. M. Vistnes, R. Lee, and G. A. Ksander, “Proteolytic activity of blowfly larvae secretions in experimental burns,” Surgery, vol. Wayman J, Nirojogi V, Walker A, Sowinski A, Walker MA. 3, no. This is not an uncommon question, and it touches upon several important elements of biotherapy, as well as palliative wound care in general. 507–514, 2007. Before you do so, it’s a good idea to put a muzzle on the animal to prevent him from biting, because he might fell a lot of pain when you touch him. 90, no. And way before doctors were readily available, indigenous healers … Maggots are kept over the wound for cycles of about 48 hours; two 48-hour cycles are usually applied each week 8).

J. This both protects the skin from irritation by the maggot’s proteolytic enzymes and forms the base of the adhesive dressing. 67, no. Insect Mol Biol. 26, no. Evidence of maggot-induced tissue growth or wound healing now comes from both laboratory and clinical studies and also suggests both mechanical and biochemical pathways. Y. O. Markevich, J. McLeod-Roberts, M. Mousley, and E. Melloy, “Maggot therapy for diabetic neuropathic foot wounds: a randomized study,” in Proceedings of the 36th Annual Meeting of the European Association for the Study of Diabetes, Jerusalem, Israel, 2000. In Armstrong’s retrospective case-control study of lower extremity wounds in nonambulatory hospice patients 75), in which the researchers demonstrated significantly better infection control and fewer amputations required in the maggot-treated group, the difference in wound healing rates between the maggot-treated group (57% healed) and the control group (33% healed) was not statistically significant. With advanced molecular and biochemical methods now at our disposal, many researchers over the past two decades have focused their attention on isolating antimicrobial proteins and other biochemicals produced by Lucilia sericata 43). MDT could be used for any kind of purulent, sloughy wound on the skin, independent of the underlying diseases or the location on the body for ambulatory as well as for hospitalized patients. Maggots also fight bacteria in their more resistant form: biofilm. Exposing unstimulated human neutrophils to crude L. sericata salivary gland extract, Pecivova and colleagues 84) measured no effect on superoxide generation or myeloperoxidase (MPO) release. 18, no. 29, pp. 77), intended to evaluate maggot-induced wound healing in venous stasis ulcers. 1–78, 1999. 2016;115(6):2403–2407. They are commonly found in the bottoms of trash cans or in an open wound on your outdoor pet. Complications. 9, pp. The authors concluded that containment of maggots reduced the effectiveness and efficiency of maggot debridement therapy, probably by preventing contact with, and/or complete access to, the wound bed. J. L. Dimarcq, E. Keppi, B. Dunbar et al., “Insect immunity. 567–572, 2012. 1, pp. W. Robinson and V. H. Norwood, “Destruction of pyogenic bacteria in the alimentary tract of surgical maggots implanted in infected wounds,” The Journal of Laboratory and Clinical Medicine, vol. In patients with bilateral wounds, only one was treated with maggot therapy, and patients were allowed to select that one. Maggot debridement therapy is used to treat and heal certain chronic wounds that have extensive areas of dead tissue. Many clinicians intuitively feel that faster debridement brings faster wound healing. Dumville et al.’s 267-subject randomized controlled trial of maggot therapy for venous stasis wounds 60) did not demonstrate any significant difference between the time-dependent decreasing bacterial burden in maggot-treated patients versus control patients, nor any significant difference in the number of MRSA-colonized wounds that were cleared. Early on, scientists believed that ingestion was the primary method by which the maggots cleared the wounds of infection 38), and subsequent researchers demonstrated that highly effective killing does indeed occur in the gut 39). Tissue quality and wound size were assessed and photographed weekly. Telford et al. R. A. Sherman, “Maggot versus conservative debridement therapy for the treatment of pressure ulcers,” Wound Repair and Regeneration, vol. 59) probably best addressed the clinical relevancy of maggot-induced disinfection by designing a case-control study of maggot therapy for lower extremity wounds in hospice patients and recording the antibiotics prescribed by the patients’ primary clinicians, as a measure of clinically significant infection. E. R. Pavillard and E. A. Wright, “An antibiotic from maggots,” Nature, vol. In the end, death may occur. Repeated measures ANOVA indicated that treatment rendered was the only factor associated with these differences. 635–639, 2002. The application of sterile Lucilia sericata larvae to an infected nonhealing wound results in the removal of necrotic tissue, disinfection, rapid elimination of infecting microorganisms, and enhancement of the healing process 4). A Handbook of Maggot-Assisted Wound Healing. A. van der Plas, J. T. van Dissel, and P. H. Nibbering, “Maggot secretions skew monocyte-macrophage differentiation away from a pro-inflammatory to a pro-angiogenic type,” PLoS ONE, vol. 15, no. The wound is thereafter cleaned and bandaged. 2, pp. P. Steenvoorde, C. E. Jacobi, and J. Oskam, “Maggot debridement therapy: free-range or contained? G. Cazander, M. W. Schreurs, L. Renwarin, C.

Mechanisms of maggot-induced wound healing: what do we know, and where do we go from here?. 1067–1070, 2004. Nonsupportive data were also available, though less commonly. Maggots have been used as a wound therapy since the beginning of civilization (1). G. Telford, A. P. Brown, R. A. M. Seabra et al., “Degradation of eschar from venous leg ulcers using a recombinant chymotrypsin from Lucilia sericata,” The British Journal of Dermatology, vol. 418–421, 1993. I. Valachová, J. Bohová, Z. Pálošová, P. Takáč, M. Kozánek, and J. Majtán, “Expression of lucifensin in Lucilia sericata medicinal maggots in infected environments,” Cell and Tissue Research, vol. In the study, maggots removed dead tissue from wounds faster than did standard surgical treatment. Antibiofilm activity is valuable because biofilm is highly resistant to the penetration and successful activity of the human immune system and antibiotics. J. Contreras-Ruiz, S. Arroyo-Escalante, Fuentes-Suarez, J. Adominguez-Cherit, C. Sosa-de-Martinez, and E. Maravilla-Franco, “Maggot therapy and infection control in venous ulcers: a comparative study,” in Proceedings of the Symposium on Advanced Wound Care (SAWC ’05), San Diego, Calif, USA, April 2005. This study revealed significantly fewer days of antibiotics compared to controls, over a 6-month observation period, indicating that the patients were cleared of their infection faster and remained infection free longer. Maggot therapy is a biotherapy in which live, disinfected maggots (fly larvae) are placed in a non-healing wound to eat the necrotic tissue and disinfect the wound. 17, pp. Evaluation of conventional therapeutic methods versus maggot therapy in the evolution of healing of tegumental injuries in Wistar rats with and without diabetes mellitus [published online ahead of print March 15, 2016].

Apply a dusting of cornstarch to inspect any left maggots in the wound. To treat myiasis in dogs, you have to clean the wound. Time to debridement differed significantly between the three groups (25.38). FDA, “510(k) Premarket Notification,” Medical Maggots, K033391, https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm?ID=13466. Prete PE. Numerous antimicrobial molecules have already been isolated in other blow flies, including the antibacterial peptide diptericin from Phormia terraenovae 51) and the antiviral alloferons from Calliphora vicina 52), the latter of which has already been commercialized. Some types of myiasis, such as a Cuterebra infestation, requires surgical removal of maggots. Using maggots in wound care: Part 1. G. Cazander, M. C. van de Veerdonk, C. M. J. E. Vandenbroucke-Grauls, M. W. J. Schreurs, and G. N. Jukema, “Maggot excretions inhibit biofilm formation on biomaterials,” Clinical Orthopaedics and Related Research, vol. 93, no. 8, pp. Scientists now know that both of these hypotheses likely contribute to wound healing: physical and electrical stimulation of healthy cells can induce the release of host growth factors, and any meaningful reduction in debris and biofilm or microbial population likely decreases inflammation and promotes wound healing. Newspapers have taken slightly different angles on a study into the use of larval therapy for leg ulcers. Figure 1. The concept of using maggots to clean and treat wounds is not new, and is one of the oldest forms of medicine. Up to 1000 maggots are introduced in the wound and left for 1 to 3 days. Sherman and Shimoda 80) reported successful wound healing without infection or dehiscence in patients surgically closed 1–21 days following maggot debridement to be 100%, compared to wounds debrided without maggot debridement therapy or those debrided with maggot debridement therapy more than 21 days before closure, which healed successfully only 68% of the time. 2010; 82(3):234–237. Their analysis revealed better outcomes in the free range group compared to the contained maggots group, despite the fact that the free range technique required fewer maggot applications and fewer total number of maggots per treatment. Twelve patients with sloughy venous ulcers were randomized to receive either larval therapy or the control hydrogel therapy. Depending on the size and depth of the wound, 50 to 1000 sterile maggots, about 24 to 48 hours old, are applied 2 to 4 times per week and left on for a period of 24 to 72 hours 94). 18, no. Disturbances in wound healing can occur when one group of proteases is deficient or out of balance with another. In fact, today, allantoin and urea are components of many cosmetics. R. A. Sherman, “Maggot therapy for foot and leg wounds,” International Journal of Lower Extremity Wounds, vol. 3, no. R. A. Sherman, K. Y. Mumcuoglu, M. Grassberger, and T. I.

Over 20,000 treatments have been supplied to over 1,000 centres, and over 50 publications now refer to the use of sterile maggots supplied by the BRU. 338, article b773, 2009. 30, no. But then, as the authors pointed out, there were so few patients with MRSA that the study was not adequately powered to see any likely difference. In another cohort of 18 diabetic subjects with 20 nonhealing neuropathic and neuroischemic foot ulcers, six wounds were treated with conventional therapy, six with maggot therapy, and eight with conventional therapy first and then maggot therapy 74). Addressing the on-going need for wound cleaning and disinfection is the paradigm behind “maintenance debridement,” and appears to be gaining support as an important strategy for treating wounds 82). 10, no. Maggot therapy is a real thing, that is really gross, and that really works. The researchers concluded that medicinal maggots might aid in wound healing by decreasing the generation of proinflammatory factors in this way, while still maintaining normal phagocytosis or apoptosis. 303–308, 2006. Throughout the centuries, the benefits of maggots in wound healing have been repeatedly reported by surgeons in the army (2-6). Indeed, maggot-associated wound healing and antimicrobial activity is likely short-lived after the maggots are removed. T. H. Gilman, “Parameter for measurement of wound closure,” Wounds, vol. But when opsonized zymosan stimulated neutrophils were exposed to high concentrations of the salivary gland extract, superoxide generation and MPO release were significantly reduced. Some clinical studies do not demonstrate these effects; instead, they leave doctors with doubts about the clinical significance of the wound healing activities that scientists see in most other clinical and laboratory studies. google_ad_client: "ca-pub-9759235379140764", No part of this website or publication may be reproduced, stored, or transmitted in any form or by any means, electronic or mechanical, including photocopy, recording, or any information storage and retrieval system, without permission in writing from the copyright holder, Assessing footwear in patients with diabetes, Causes, prevention, and treatment of epibole. 5, pp. 7, no. 2008;24(Suppl 1):S76–S80. In a cohort of 63 patients with 92 pressure ulcers, followed for at least 8 weeks while receiving either standard wound care (as prescribed by the hospital’s wound care team), or maggot therapy (two 48- to 72-hour cycles per week), maggot-treated wounds were debrided four times faster than control wounds (0.8 cm²/week versus 0.2 cm²/week) 30).

Cullum, and T. Sheldon, “The debridement of chronic wounds: a systematic review,” Health Technology Assessment, vol. In this study population, the probability of healing may have had more do to with the patients’ underlying circulatory compromise, malnutrition, and poor physiologic health than with the treatments rendered. One of the major advantages of MDT is that the … Certainly, the use of maggots in wound care isn’t a novel idea. Larval Therapy for Chronic Cutaneous Ulcers. Patients in the intervention group received maggot therapy with larvae of Lucilia sericata. 3, pp. 9, article 24, 2010. For those wounds that did heal, wound healing was much faster in the maggot-treated wounds than in the control wounds (18 weeks versus 22 weeks). In order to debride necrotic tissue, larvae (ie, maggots) produce a mixture of proteolytic enzymes, including collagenase, that breaks down the necrotic tissue to a semi-liquid form to be absorbed and digested. 2007;61(3):488–493.

The best way to consider the role of maggots in wound healing may be to first review the wound healing process in general and then to separately summarize the literature concerning each major wound healing effect of the maggots. Wayman et al 98) compared the cost of larval therapy with hydrogel dressings in the treatment of necrotic venous ulcers. 180, no. Among the early theories about maggot-induced wound healing were that the simple removal of debris and microbial killing 61) or the action of crawling over the clean wound bed 62) might be enough to stimulate wound healing. Clinical evidence of maggot-induced disinfection and growth stimulation was not strong enough to convince regulators at that time. R. D. Wolcott, J. P. Kennedy, and S. E. Dowd, “Regular debridement is the main tool for maintaining a healthy wound bed in most chronic wounds,” Journal of Wound Care, vol. The cost effectiveness of larval therapy in venous ulcers. The physical mechanics of maggot debridement 19) are readily apparent to anyone who has seen the larvae under the microscope. Valachová and colleagues 50) demonstrated that lucifensin expression was increased in response to microbial ingestion only in the fat body; lucifensin was expressed in the salivary glands throughout the larval period and not significantly affected by microbial ingestion. Each maggot is capable of removing 25 mg of necrotic material from the wound within just 24 hours 18). 2014;23(6):779–787. Wounds. Larval secretions also contain deoxyribonuclease (DNAse), able to degrade both microbial DNA and also human DNA in necrotic debris 28). 794–797, 2008. Numerous case reports have purported wound disinfection following maggot therapy, but controlled clinical evidence of maggot-induced antimicrobial activity has been sparse, until recently. 18, no. The netting is then bunched up to create a cage for the larvae, placed on the wound, and secured to the hydrocolloid dressing by waterproof adhesive tape. 505–510, 1997. 95–101, 1990. 5, pp. There is evidence that maggot therapy may help with wound healing. 54–56, 2009. But ever since maggot therapy became a common practice 9), careful observers also noted other effects on the wounds: microbial killing (disinfection) and hastened wound healing (growth stimulation) 10). Debridement of necrotic tissue was achieved in just 10 days with maggot therapy. 20, pp. 28, no. 6, pp. 4. Maggots are the small, slimy larvae of the common household fly, and they can grow in any region that is moist, dark and secluded. By the end of maggot debridement, MRSA colonization was eliminated from all but 1 of the 13 ulcers (efficacy = 92%); no complications or patient complaints were encountered. Maggots and wound care. 1997;60(8):505–510. Biosurgery (syn. 446–451, 2003. 65, no. 1318–1322, 1999. 2002;41(10):635–639. By Ron Sherman MD, MSC, DTM&H This week I was asked about using maggot therapy for treating a tumor that eroded through the skin, causing a foul-smelling, necrotic draining wound. They also pointed to the antimicrobial activity of ammonia-containing byproducts of the maggots’ digestion of tissue proteins and the resulting alkalinized wound bed 42). 2, pp. 6-7, pp. 41, no. In Tantawi et al.’s case series 56), 13 diabetic ulcers in 10 subjects similarly demonstrated significant decreases in the number of microbial species and the colony counts after maggot therapy. Vistnes et al. 284, no. 10, pp. 10, no. Hobson 22). M. J. Yet, it has been difficult to find any large randomized controlled trial that demonstrates this to be true 81).
