About this study

Official title: Cold Plasma Therapy for Acceleration of Wound Healing in Superficial, Infected Diabetic Foot

Diabetic foot is a common complication of diabetes mellitus and requires specialized treatment. Wounds are characterized by persistent infection and chronic inflammatory processes, impeding well directed matrix remodelling and wound closure. Cold plasma applications have demonstrated beneficial effects on wound healing in several case reports. The investigator-initiated "Kaltplasma Wund (KPW)-Trial" was performed to prove beneficial effects of cold plasma in wound healing in a prospective, placebo-controlled, randomized bi-center study.

Read the detailed description

Diabetic foot (DF) is a major complication in patients with diabetes leading to increased risk of hospitalization, lower limb amputation, and death, as well as a significant decrease in quality of life. During lifetime the risk for developing DF is assumed to be 25%; with 30% of DF resulting in lower limb amputation. If compared to general population people with diabetes have a 20-fold higher risk for amputation. Diabetes mellitus is the leading cause of lower limb amputation. Ulceration and impaired wound healing are commonly associated with common co-morbidities; the increased risk of infection amongst patients with diabetes is driving chronification and accounts for lack of wound healing.

Non-thermal atmospheric pressure plasma has been proposed as a tool for various biological and medical applications relying on its capacity to reduce bacterial load in the wound and to initiate wound healing. Biological plasma effects are largely dependent on plasma-generated reactive species in the gas phase, which subsequently diffuse or react with proteins and lipids in cells or tissues.

Thus, the objective of this placebo-controlled patient-blinded study was to show that application of cold plasma in addition to standard care treatment compared to placebo could accelerate wound healing in terms of more rapid and clinical meaningful wound surface regression. Wound closure progression and microbiological analysis were monitored time dependently to prove the effects. Patient's well-being and subjective perceptions were evaluated during treatment.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Argon Plasma JetDevice

    Cold Plasma (CP) therapy is applied in the first week of treatment on a daily schedule, in the second week CP is applied every second day. In total, 8 applications are performed with a one day schedule variance.

  • PlaceboDevice

    Sham Cold Plasma (sham-CP) (switched off Electric field, no plasma production, just gas) therapy is applied in the first week of treatment on a daily schedule, in the second week sham-CP is applied every second day. In total, 8 applications are performed with a one day schedule variance.

  6. treatment related side effects - formation of keloids

    question to evaluate potential side effects of the therapy: formation of keloids will be answered in a "yes" or "no" fashion and reported

    Measured: treatment period of max 15 days

  7. treatment related side effects - presence of skin irritation

    question to evaluate potential side effects of the therapy: presence of skin irritation will be answered in a "yes" or "no" fashion and reported
