Study summary

The feet of diabetic patients continue to be an important problem in medicine. In general, patients with diabetic foot have some sort of amputation, especially in underserved populations. It is clearly necessary to develop novel treatment strategies for this worldwide health problem. Photodynamic therapy (PDT) , is a low cost and highly effective alternative treatment concerning infections avoiding amputations in the diabetic foot.

Read the detailed description

Patients with infected diabetic foot were grouped according to the Wagner system for classifying foot lesions. All patients presented Wagner Grade 3 classification, with osteomyelitis in one or more toes. The study included only patients who had circulatory viability.

For PDT treatment the fistula and/or ulcer was used as a gateway to the bone. The treated area (bones and fingers) was irrigated with a solution of phenothiazinium salts. After that, light irradiation was performed with optical fibers or led device above the wound. PDT treatment always in outpatients, once or twice a week.

What researchers measure

Primary outcomes

  1. Infection control

    blood count - leucocytes for infection

    Time frame: every month until three months , when blood count- leucocytes reach the standard value.

Secondary outcomes

  1. Osteomyelitis evaluation

    Radiographs were used when patients presented osteomyelitis

    Time frame: once a month, until three months, when X-ray shows bone reconstitution .
