Clinical Trial Summary

Diabetic foot ulcer affects 10.5% of the Brazilian/world population, compromising the quality of life of these patients and burdening the public health system. Studies show that antimicrobial photodynamic therapy (aPDT) accelerates its repair, however, there is not enough evidence for decision-making in clinical practice, which prevents this treatment from being used on a large scale. Controlled and randomized clinical studies are needed to increase the level of evidence on this subject, promoting the improvement of the quality of life of people affected by diabetic foot ulcers. The aim of this study is to analyze the action of antimicrobial photodynamic therapy on the quality of the wound and tissue repair process using the Bates-Jensen scale in people affected by diabetic foot wounds.

Description:

Diabetic foot ulcer affects 10.5% of the Brazilian/world population, compromising the quality of life of these patients and burdening the public health system. Studies show that antimicrobial photodynamic therapy (aPDT) accelerates its repair, however, there is not enough evidence for decision-making in clinical practice, which prevents this treatment from being used on a large scale. Controlled and randomized clinical studies are needed to increase the level of evidence on this subject, promoting the improvement of the quality of life of people affected by diabetic foot ulcers. The aim of this study is to analyze the action of antimicrobial photodynamic therapy on the quality of the wound and tissue repair process using the Bates-Jensen scale in people affected by diabetic foot wounds. A clinical, controlled, randomized and double-blind study will be carried out. Patients will be randomized (1:1) into 2 groups: (1) experimental (n= 45) - standard care from the Polyclinic wound sector + aPDT and (2) control (n= 45) - standard care + simulation of use aPDT with equipment off). All patients will be seen three times a week, with 10 sessions of aPDT or simulation performed by the same operator. A cluster with an average radiant power of 100 mW, radiant energy per emitter of 6 J/cm² of red light (wavelength 660 nm) will be used. The research will be carried out in a Municipal Health Center in the city of Rio de Janeiro. Patients affected by neuropathic wounds of the diabetic foot, assisted by the Programmatic Care Health Coordination will be included 5.1. The initial assessment will consist of collecting data from medical records to establish the sociodemographic and clinical profile of patients affected by diabetic foot injuries.) by a researcher blinded to the interventions. This scale assesses the size of the lesion, depth, borders, detachment, type of necrotic tissue, amount of necrotic tissue, type of exudate, amount of exudate, skin color around the wound, perilesional tissue edema, perilesional tissue hardening, granulation tissue, epithelialization. As secondary outcomes: the sensitivity of the foot will be evaluated, through neurological evaluation with tuning fork and monofilament, the instrument for assessing quality of life - Diabetes-21, the Wagner Scale, the evaluation of the degree of ischemia by the Fontaine scale and Runtherford, the WiFi and Taxonomy Nursing Outcomes Classification scale that assesses skin integrity. Data from this research will be collected after approval by the ethics committee of Universidade Nove de Julho and the City Hall of Rio de Janeiro.

Primary	Bates-Jensen Wound Assesment Tool	The Bates-Jensen Scale is an effective tool for wound assessment. In its current version, it includes 13 characteristics to be evaluated: size, depth, edges, undermining, type of necrotic tissue, amount of necrotic tissue, exudate type, exudate amount, skin color around the wound, perilesional tissue edema, perilesional tissue induration, granulation tissue, and epithelialization.; Each item on the scale is scored from 1 to 5: minimum values indicate the best wound condition,; maximum values represent the worst condition.; The total score is obtained by summing all the items and can range from 13 to 65 points, with HIGHER scores indicating WORSE wound conditions.

Secondary	Vibration Sensation	To assess vibratory sensitivity, a 128Hz tuning fork is applied to a bony area (e.g., elbow, clavicle, sternum, chin) to demonstrate the expected sensation. The participant then closes their eyes, and the tuning fork is applied with constant pressure to the dorsal side of the hallux's distal phalanx or another toe if the hallux is missing. If all phalanges are amputated, it's applied to the nearby area. The tuning fork is held in place until the participant reports the vibration has ceased. The test is repeated twice, with at least one "simulated" application where the tuning fork doesn't vibrate. A positive test result is when the participant correctly identifies vibration in at least two out of three applications, while a negative result is when they inaccurately identify vibration in two out of three applications, indicating a lack of vibratory sensitivity (IWGDF, 2019).
