Abstract:
5 patients with diabetic-foot were treated by maggot therapy. The most serious case was in a 75-year-old man who had gangrene and osteomyelitis of the right foot. Proteus mirabilis, Enterococcus sp., Providencia stuartii and Staphylococcus spec. (coagulase positive) were isolated from lesions which did not respond to antibiotic therapy. The patient had twice refused amputation but agreed to maggot therapy. Larvae of the sheep blowfly Phoenicia (Lucilia) sericata were used for twice-weekly treatment over a period of 7 months. Sterile larvae were applied to the wound and replaced every 3-4 days. After 4 months of treatment, the necrotic tissue around the toes and on the sole of the foot detached from the healthy tissue. During the last 3 months of treatment the larvae removed the remaining infected tissue. As therapy progressed, new layers of healthy tissue covered the wound. The offensive odor associated with the necrotic tissue and the intense pain in the foot decreased significantly. At the end of therapy, during which there were no complaints of discomfort, he was able to walk. In the 4 other patients who had relatively superficial gangrene, the maggots debrided the wounds within 2-4 weeks. Thereafter treatment was continued with antibiotics. Maggot therapy can be recommended in cases of intractable gangrene and osteomyelitis, when treatment with antibiotics and surgical debridement have failed.
Insights
Maggot therapy effectively treated diabetic foot ulcers with gangrene and osteomyelitis. This approach removed necrotic tissue, promoting healing when antibiotics failed.
Area of Science:
- Medical Entomology
- Wound Healing
- Infectious Diseases
Background:
- Diabetic foot ulcers are a significant complication, often leading to severe infections like gangrene and osteomyelitis.
- Antibiotic therapy and surgical debridement are standard treatments but can be ineffective in complex cases.
Observation:
- Five patients with diabetic foot complications underwent maggot therapy using sterile larvae of *Phoenicia (Lucilia) sericata*.
- A severe case involved a 75-year-old man with gangrene and osteomyelitis unresponsive to antibiotics, who opted for maggot therapy over amputation.
Findings:
- Maggots successfully debrided necrotic and infected tissue over several months, promoting the growth of healthy tissue.
- Significant reduction in wound odor and pain was observed, with the patient regaining mobility.
- Superficial gangrene cases showed wound debridement within 2-4 weeks, followed by antibiotic treatment.
Implications:
- Maggot therapy presents a viable alternative for intractable diabetic foot gangrene and osteomyelitis when conventional treatments fail.
- This method offers a less invasive option, potentially preventing amputations in severe diabetic foot cases.
- Further research into maggot therapy protocols could optimize outcomes for complex wound management.
