therapy in diabetic foot ulcers. 916–917, 1957. J. L. Dimarcq, E. Keppi, B. Dunbar et al., “Insect immunity. Indeed, twice as many wounds in the maggot-treated group completely healed during the period of observation (39% within an average of 12 weeks versus 21% within an average of 13.4 weeks). 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. 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. A. G. Smith, R. A. Powis, D. I. Pritchard, and S. T. Britland, “Greenbottle (Lucilia sericata) larval secretions delivered from a prototype hydrogel wound dressing accelerate the closure of model wounds,” Biotechnology Progress, vol. 2, pp. Markevich YO, McLeod-Roberts J, Mousley M, Melloy E. Maggot therapy for diabetic neuropathic foot wounds. 5, pp. When no longer needed, the cells undergo apoptosis and are removed or engulfed by other cells (i.e., macrophages). 455–466, 2010. The maggots can be removed by forceps. Nonsupportive data were also available, though less commonly. 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. 39, no. 4, pp. R. P. Hobson, “On an enzyme from blow-fly larvae (Lucilia sericata) which digests collagen in alkaline solution,” Biochemical Journal, vol. Repeated measures ANOVA indicated that treatment rendered was the only factor associated with these differences. 40, no. 77), intended to evaluate maggot-induced wound healing in venous stasis ulcers. Their results may have resulted from the decreased competition by gram positive microbes. During World War 1, William Baer, an orthopedic surgeon, noted the benefits of using maggots in compound fractures. J. Buchman and J. E. Blair, “Maggots and their use in the treatment of chronic osteomyelitis,” Surgery, Gynecology and Obstetrics, vol. Brown, A. Horobin, D. G. Blount et al., “Blow fly Lucilia sericata nuclease digests DNA associated with wound slough/eschar and with Pseudomonas aeruginosa biofilm,” Medical and Veterinary Entomology, vol. This paper is a literature review of maggot debridement therapy in the clinical setting today and addresses the costs … Postgrad Med J. Antibiofilm activity is valuable because biofilm is highly resistant to the penetration and successful activity of the human immune system and antibiotics. Larvae are covered by minute spines which scrape along the wound base as the maggots crawl about, loosening debris as does a surgeon’s rasper or file (Figure 1). 581–586, 1934. The investigators monitored 8 specific outcome measures: (1) complete healing without any other intervention; (2) complete healing by secondary intervention (e.g., split-skin graft); (3) wound free from infection and less than one-third of the initial size; (4) wound clean but not decreased in size; (5) no difference in wound size or character; (6) wound worsened; (7) minor amputation was still required (e.g., partial toe amputation); and (8) major amputation was still required. Debridement refers to the removal of dead, damaged, or infected tissue to improve the healing potential of the remaining healthy tissue. Experiments performed by Barnes et al 89) have demonstrated that the blowfly Lucilia sericata (Lucilia (Phaenicia) sericata) larvae excretions/secretions are able to inhibit bacteria growth in both stationary and exponential phases. Use a pair of tweezers to remove maggots that do not … 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). But most patients were not followed more than 10 weeks, and this difference was not statistically significant. Maggots are in the news today. 3, no. Both factors increased the proliferation of fibroblasts stimulated by epidermal growth factor or interleukin 6. While this can be thought of as a subset of actions which promote wound healing, they are separated out for the purpose of this discussion because these actions may also play important roles in disinfection, if not also debridement. 4, pp. Larval secretions also contain deoxyribonuclease (DNAse), able to degrade both microbial DNA and also human DNA in necrotic debris 28). 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. 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. 1318–1322, 1999. 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.
