Topical Insulin Dressing on Management of Diabetic Foot Ulcers, Would it Help?

This study aimed to find out the advantages of topical insulin in the management of diabetic foot ulcers over the conventional wound saline dressing.

Detailed Description

Non healing foot ulcers constitute a major problem that plagues those with diabetes due to angiopathy and neuropathy. It is well known that the basic cellular and molecular mechanisms that result in wound healing involve cell adhesion, migration, proliferation, differentiation, and apoptosis.

The molecular mechanisms of insulin signaling and its metabolic effects have been well studied in its classical target tissues. Insulin stimulates the growth and development of different cell types and affects proliferation, migration, and secretion by keratinocytes, endothelial cells, and fibroblasts.

  • Participants who were able to and willing to participate in the study voluntarily who could come for dressings on a daily basis, or patients who agreed for admission for the duration of treatment were included in the study.
  • Patients having ulcer below the ankle on the dorsal or plantar aspect of the foot.
  • Patients with grade I and grade II ulcers of Wegener's Classification without significant growth of granulation tissue.
  • Patients with controlled blood glucose levels between 110 and 130 gm/dl. Hemoglobin A1c was 7.1 ± 0.34.
  • Non heavely infected wounds without significant growth of granulation tissue.

Exclusion Criteria:

  • X-ray showing features of osteomyelitis.
  • Duplex showing significant atherosclerotic changes and venous abnormalities like varicosities.
  • Malnutrition and uncontrolled diabetes mellitus.
  • Other clinically significant medical conditions that would impair wound healing like any hepatic, renal, immunological and neurological disease and coagulopathy.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Group A (soluble insulin (Actrapid))
The ulcers were cleaned with normal saline and then irrigated with 4 units (0.1 ml) of human soluble insulin (Actrapid) in 1 ml normal saline (0.9%) for every 10 cm square of the wound.
