Brief Summary

Prevalence of diabetic foot ulcers are reported to be 15% in patients who suffer from diabetes and ulcerations are present in 84% of all diabetes-related amputations. Peripheral neuropathy leading to unperceived trauma seems to be the major cause of diabetic foot ulcers with 45-60% of ulcers to be considered merely neuropathic and 45% of mixed, neuropathic and ischemic etiology. Ulceration of lower limb is one of the most common complications related with diabetes and one of the major causes for hospitalization of diabetic patients. The most significant contributors to diabetic lower limb ulceration are neuropathy, deformity, uncontrolled elevated plantar pressure, poor glycemic status, peripheral vascular disease, male gender and duration of diabetes. Treatment of lower limb ulcers imposes an enormous burden on health care resources worldwide, and at least 33% of all expenses are spent to treat diabetic ulcers manifested as a complication of diabetes. Although at least 170 topical wound care products are available, evidence of the superiority of one over another is tenuous, well-designed randomized, controlled trials are rare, and the number of case-control or observational studies is limited. In recent years, salve prepared from Norway spruce (Picea abies) resin has successfully been used in medical context to treat both acute and chronic wounds and ulcers of various origins. The objective of this prospective, randomized and controlled clinical trial is to investigate healing rate and healing time of neuropathic diabetic foot ulcer in patients, who are suffering from infected fore- or mid-foot ulceration (PEDIS-classification ≥ Grade II; 19) originated from Type I or II diabetes, and in patients whose diabetic ulcerations are candidates for topical treatment with resin (Study treatment) or octenidine (Control treatment). In addition, factors contributing with delayed healing of ulceration, antimicrobial properties, safety and cost-effectiveness of the resin salve treatment and control treatment will be analyzed.

Study Arms (2)

Resin salve treatment

EXPERIMENTAL

The resin salve may be spread directly onto the diabetic ulcer, after which the area is covered with a bandage suitable for local wound care. The bandage prohibits salve from moving away from the ulcer area. If the skin condition is more widespread or contains cavities or fistulae, the salve may be spread as a film with a thickness of at least 1 mm onto a gauze or gauze ribbon that is then used to fill the cavity or fistulae channel. Bandages are changed every 1-3 days, depending on the degree of infection and amount of ulcer secretion.

Device: Resin salve treatment

Octenidine treatment

ACTIVE COMPARATOR

Octenidine treatment is implemented with the similar manner as resin salve treatment by using sterile gauze that is impregnated with the octenidine dihydrochloride.

Device: Octenidine treatment

Interventions

Resin is collected in the municipality of Kolari, Finland, from the trunks of full-grown Norway spruce (Picea acies) trees. Bark and other impurities are removed mechanically. The resin is then liquefied and purified by filtering. Resin salve is composed of a 10% (w/w) mixture of purified spruce resin in a standardized salve base. None of the components of the salve base have antibacterial properties. Resin salve is produced from the pure resin to the final product in accordance with the Good Manufacturing Standards (GMP) and it holds the European CE mark (Abilar 10% Resin Salve, Repolar Ltd., Espoo, Finland, CE 0537).

Also known as: Abilar 10% Resin Salve
Resin salve treatment

Octenidine dihydrochloride is a cationic surfactant and bis-(dihydropyridinyl)-decane derivative, used in concentrations of 0.1-2.0%. It is similar in its action to the quaternary ammonium compounds, but is of somewhat broader spectrum of activity. Octenidine is currently increasingly used in continental Europe as a substitute for quats or chlorhexidine (with respect to its slow action and concerns about the carcinogenic impurity 4-chloroaniline) in water- or alcohol-based skin, mucosa and wound antiseptics. In aqueous formulations, it is often potentiated with addition of 2-phenoxyethanol.

Also known as: Octenisept
