Brief Summary

Diabetes mellitus is a major public health problem and it is estimated that 300 million individuals will be affected by the year 2030. Non-diabetic ulcers are one of the most frequent complications of this disease and, if untreated, can lead to the amputation of lower limbs. Thus, there has been growing interest in the use of light emitting diode (LED) devices to accelerate the tissue repair process and lower the cost of ulcer treatment in this population. The Mandaqui hospital complex is a general, tertiary, teaching hospital that is a reference center for revascularization surgery and endovascular treatment in Brazil. The aim of the proposed study is to evaluate the action of LED therapy on the complete healing of ulcers following minor amputations in patients with Diabetes mellitus. Methods: A single-center, randomized, controlled, double-blind, clinical trial with two parallel groups will be conducted following the criteria of the CONSORT Statement. The project will be registered with www.clinicaltrials.gov. The sample will be composed of 40 patients with a diagnosis of Diabetes mellitus in follow up at the vascular clinic of Mandaqui hospital complex who meet the inclusion criteria. The control group (n = 20) will receive traditional rayon bandages with essential fatty acids and secondary coverage with gauze, which will be changed on a weekly basis. The treatment group (n = 20) will be submitted to LED therapy (635 nm; 4 J/cm2; 10 minutes) with weekly applications and the ulcers will also receive the traditional bandage treatment described above. The patients will be followed up until the complete closure of the ulcer, which will be the primary outcome. The ulcers will be examined on a weekly basis by a researcher with no awareness regarding the allocation of the individuals to the different groups and will assess, signs of infection, edema, redness, heat and the presence of gangrene. Photographs of the ulcers will also be taken for the subsequent determination of the area. Another researcher with no knowledge regarding the allocation of the participants will measure the surface of the ulcers with the aid of the ImageJ software program. The data will be submitted to appropriate statistical analyses. After closure of the ulcers, the patients will be followed up for a period of six months.

Outcome Measures

Primary Outcomes (1)

  • Wound closure

    The primary outcome will be the complete closure of the ulcer, which is defined as 100% epithelialization of the operated surface with no exudate, draining or need for bandages.

    6 months

Secondary Outcomes (3)

  • Time for closure

    up to 6 months

  • Ulcer closure rate

    up to 6 months

  • Cost-benefit ratio of ulcer treatment following minor amputations

    up to 6 months

Study Arms (2)

Control group

ACTIVE COMPARATOR

Control group - gold standard: Conventional ulcer treatment with Rayon® and essential fatty acids (Dersani®). Cleaning of the surgical wound will be performed with saline solution. The wound will then be covered with a sterile polyethylene film, over which the LED plate will be positioned for placebo treatment (emission of sound, but with the device switched off). After 10 minutes, the LED plate and polyethylene film will be removed and the surgical wound will be covered with rayon moistened with essential fatty acids (following the standard protocol of the hospital), followed by the application of gauze and finalization with a crepe bandage.

Procedure: Control group

LED group

EXPERIMENTAL

LED group: Cleaning of the surgical wound will be performed with saline solution and the wound will be covered with a sterile polyethylene film, over which the LED plate will be positioned for active treatment with the device switched on. After 10 minutes, the LED plate and polyethylene film will be removed and the surgical wound will be covered with rayon moistened with essential fatty acids (following the standard protocol of the hospital), followed by the application of gauze and finalization with a crepe bandage.

Radiation: LED

Interventions

LEDRADIATION

A device with 36, rectangular, red LEDs, registered with the Brazilian National Health Surveillance Agency (ANVISA authorization nº 8.04554.6), λ = (650 ± 20) nm, with an output power of 324 mW and an output area of 2.54 cm2 (Cosmedical, Brazil), will be enveloped with sterile, disposable, plastic wrap (transparent in the red wavelength) to permit contact with the skin for ten minutes during each session. The plastic wrap will be changed after each use. The amount of energy delivered will be 194.4 J.

Also known as: Photobiomodulation with light emmiting diode (LED)
LED group
Control groupPROCEDURE

Conventional ulcer treatment with rayon® (Polar Fix, Polar Fix, Mauá, SP, Brazil) and essential fatty acids (Dersani®, Saniplan, Daudt, São Paulo, SP, Brazil) (composition: decanoic acid, caprylic acid, hexanoic acid, lauric acid, linoleic acid, lecithin, retinyl palmitate, tocopheryl acetate and alpha-tocopheryl).
