No single broad-spectrum regimen, optimal duration or route of antibiotic therapy has been shown to be more effective than another in the treatment of patients with diabetic foot ulcers. They debride (clean) the wound by dissolving dead and infected tissue with their proteolytic, digestive enzymes; They disinfect the wound (kill bacteria) by secreting antimicrobial molecules, by ingesting and killing microbes within their gut, and by dissolving biofilm; They stimulate the growth of healthy tissue. Maggot therapy was a common procedure in medicine until the general use of antibiotics replaced the practice in the 1940s.

The primary study outcome measure was complete healing at 24 weeks of treatment. [21][22], A survey of US Army doctors published in 2013 found that 10% of them had used maggot therapy. Infection can thus be avoided by not lying on, or laying out clothing on, potentially contaminated ground, or by ironing clothes that have been exposed.

However, it has to be borne in mind that excessive flushing can drown the larvae.

Larvae are retained on the wound for about 48h in cage-like dressings. Exceptionally, when treating patients with leg ulcers associated with ischaemia, an increase in pain may be reported when MDT is used.47 The origin of this reported pain during maggot application is not known, since the wound healing effect of maggots is not related to their direct crawling action on the wound surface.

Once the laboratory colony is established, eggs are sterilized in an antiseptic bath (e.g., sodium hypochlorite, formalin, or hydrogen peroxide) and held for hatching. Apligraf (Organogenesis, Canton, Mass) is a cultured bilayer cellular construct (BLCC) originating from neonatal foreskin. Ihis is an excellent review for professional use in sterile maggott therapy. Peter Moss, Nick J. Beeching, in Infectious Diseases (Third Edition), 2010, (See healthmap.org for outbreaks of Myiatic), The house fly, Musca domestica, has no requirement for developing in mammalian tissue, but is occasionally found in dead tissue or under plaster casts.
Leider ist ein Problem beim Speichern Ihrer Cookie-Einstellungen aufgetreten. Their mass production is mainly done in a natural way, were the cochineal Dactylopius spp. These medical-grade maggots have the natural instinct to crawl away from living skin to find dead matter, which they consume before moving on to find more necrotic tissue. One to three weeks later, adult flies eclose (emerge).

Furthermore, maggots produce excretions (ES) which possess proteolytic enzymes that can dissolve the dead and/or infected matrix on the wound bed.36 The longer standing hypothesis was that the mechanical debridement aspect was the responsible mechanisms for the effectiveness of MDT, but current studies do not support this and offer evidence that the chemical mechanisms are the underlying aspects of its success.37 The excretions and secretions of maggots contain allantoin, sulfydryl radicals, calcium, cysteine, glutathione, embryonic growth stimulating substance, growth stimulating factors for fibroblasts, carboxypeptidases A and B, leucine aminopeptidase, collagenase and serine proteases (trypsin-like and chymotrypsin-like enzymes, metalloproteinase and aspartyl proteinase).38 A further in vivo study supports the theory that the direct mechanical action of free-range maggots is limited.

A hole appears at the centre of the swelling, through which the posterior tip of the larva (including its breathing spiracle) can be seen. The sterilized maggots are placed on the wound surface within a net pouch, and fixed by an absorbent dressing. Honey has also returned to the wound management portfolio (Molan 1999). Subsequently, maggot therapy became acceptable for wound treatment, particularly in the United States (McKeever, 1933). After being placed on the infected area, the maggots go to town eating and cleaning, as they only have a taste for rotting flesh. This approach has been used by people since ancient times for treating deep, chronic, or extensive surface wounds.


Ihre zuletzt angesehenen Artikel und besonderen Empfehlungen. In moving about the wound while feeding, maggots stimulate the formation of desirable granulation tissue and secrete calcium carbonate, ammonia, and allantoin (a substance that promotes wound healing).

Maggot therapy is a type of biotherapy involving the introduction of live, disinfected maggots (fly larvae) into the non-healing skin and soft tissue wound(s) of a human or animal for the purpose of cleaning out the necrotic (dead) tissue within a wound (debridement) and disinfection.

[14] Other bacteria like Pseudomonas aeruginosa, E. coli or Proteus spp. 11.14). Two years later, after treating 98 children, his findings were published posthumously. There is an overview of flies and maggots, a history of maggot therapy, and information on maggots' mode and … [1] Aversion to maggots, and lack of training have kept clinicians and patients from utilizing this method in modern times. then I heard about maggot therapy. In addition to detailed descriptions of the clinical problems for which maggots can be used, there are case studies and questions and answers from medical practice.

In such cases, larvae hatching from eggs laid on a person penetrate the skin and wander in the epidermis, producing visible, sinuous, inflamed tracks accompanied by irritation and pruritus. The majority of these therapeutic strategies have limited data supporting their efficacy. Although such cases are seldom serious, adverse effects can be prolonged and may require purging of the alimentary tract to resolve the problem. [7] Dressings are also designed to minimize the uncomfortable tickling sensation that the maggots often cause.[8]. [23], In January 2004, the U.S. Food and Drug Administration (FDA) granted permission to produce and market maggots for use in humans or animals as a prescription-only medical device for the following indications: "For debriding non-healing necrotic skin and soft tissue wounds, including pressure ulcers, venous stasis ulcers, neuropathic foot ulcers, and non-healing traumatic or post-surgical wounds. Currently there are two modes of application of MDT. April 2015, The book was very succinct, but I would have liked to know more about its use. A dermal cavity containing the maggot is surrounded by an intense inflammatory response, which may be very itchy and painful. Treatments can be administered in the hospital, clinic, nursing home, or at home. The molten metal was poured into the mold through the hole(s) and allowed to solidify, after which the mold was removed. Carmine dye was used by ancient Egyptians, Greeks, and Persians and by preColumbian civilizations in the New World as early as 2000 years ago (Chávez-Moreno et al., 2009; Greenfield, 2005Chávez-Moreno et al., 2009Greenfield, 2005). A moist, exudating wound with sufficient oxygen supply is a prerequisite. Infirm persons are at particular risk, as are people who work and live in close proximity to livestock operations where carrion and suitable hosts are more available.

Patients with diabetes are more prone to peripheral artery disease (PAD) than patients without diabetes. Patients with active diabetic foot disease should be referred to a multidisciplinary diabetic foot care service. Why does wound healing get slower as we age? Research and development costs for these products were high and unfortunately this has spilt over into dressing costs. The maggots not only dissolve the dead skin with their digestive enzymes to debride the wound by also disinfect as they work. [27], However, there have not been many case studies done with maggot debridement therapy on animals, and as such it can be difficult to accurately assess how successful it is. Debridement is required to excise nonviable tissue and should be aggressive, particularly at the initial evaluation. Only a small subgroup of patients with infected diabetic foot ulcers need to be treated with intravenous antibiotics; again, this is a decision made on clinical grounds. Clinical signs appear about 10–14 days after the bot fly eggs have been deposited on the skin in outdoor situations.
