Abstract

Background: Chronic plantar ulcers are common problems for leprosy patients with numb feet due to their prolonged healing time. Chronic plantar ulcers affect the quality of life of patients and can lead to more serious complications, such as disability and deformity, if not handled appropriately. Wound-care products in the market, however, give unsatisfactory results. One factor in the delayed healing of chronic plantar ulcers due to leprosy is the lack of growth factors and cytokines in the wound due to reduced blood supply. We speculated that application of human amniotic membrane stem cell (hAMSC) secretome, which contains growth factors and cytokines, could improve wound healing.

Aim: To evaluate the effect of topical application of a hAMSC secretome gel on wound healing of chronic plantar ulcers due to leprosy.

Materials and methods: We recruited 11 patients after leprosy treatment with chronic plantar ulcers due to leprosy. hAMSC secretome gel was applied topically to ulcers every 3 days for up to 2 months. Ulcer size and possible side effects or complications from gel application were evaluated weekly.

Results: The ulcers of 8 of 11 patients (72.7%) completely healed, the ulcers of 2 patients (18.2%) partially healed, and the ulcers of 1 patient (9.1%) persisted. No ulcers became worse.

Conclusion: hAMSC secretome was found to be an efficacious and well-tolerated alternative therapy for chronic plantar ulcers due to leprosy.

Keywords: Human amniotic membrane stem cell secretome; leprosy chronic plantar ulcers; wound healing.
