Wound Healing Endpoint and Recurrence

This study is a continuation of a previously approved protocol conducted at Ohio State University and Indiana University. The first two aims of the original protocol have been completed, and this protocol will finish enrollment for the third aim, comparing Hi TEWL and Low TEWL measurements, and whether a HiTEWLmeasurement indicates a seemingly healed wound is more likely to recur/reopen toa new wound. Of the 105 desired subjects, 62 subjects have already been recruited and completed their study participation at the previous university. 43 additional subjects will be recruited to complete the enrollment goal here at the University of Pittsburgh.

Assessment of Non Vascular Risk Factors for Severity of Diabetic Foot Ulcers (DFUs)

Diabetes mellitus is a chronic disease that occurs either when pancreas does not produce enough insulin or when the body can't use it effectively. Diabetes mellitus include : type 1(insulin deficiency) , type 2 ( insulin resistance ) , gestational diabetes, maturity onset diabetes of the young ( MODY) , neonatal DM , wolfram syndrome, latent autoimmune diabetes in adults ( LADA ) , type 3 c diabetes, steroids - induced diabetes, cystic fibrosis disease ,Type 5 diabetes( Malnutrition related diabetes) which affect between 20-25 million primarily in Asia \& Africa. According to WHO the number of living people with diabetes rose from 200 million in 1990 to 830 million in 2022 . According to IDF : The latest atlas 2025 report that 11.1% or 1- 9 of adult population ( 20 - 79 ) is living with diabetes, which 4 in 10 unaware of their condition. One of the serious complications is Diabetic foot ulcers . The global prevalence of DFU is around 6.3 % while the annual incidence reported between9.1 to 26.1 million cases, that's mean that 1 in 16 of diabetic patients experiences a DFUs . DFUs can be defined as wound or ulceration on the foot of diabetic patients due to a combination of factors such as neuropathy, peripheral artery disease, trauma or pressure . DFUs can lead to serious complications up to death like infection, osteomyelitis, limb amputation that significantly impact a person's quality of life, causing pain, disability and psychological distress. Beyond that immediate impact on patients, but also affect their families, and the healthcare system so it's considered as an economic burden due to health care costs and lost productivity. So to solve the problem we should know what cause it first and so we can prevent it before happening, not just finding a solution and that will affect not just the patients and their families, but also the country. Non vascular risk factors significantly impact DFU severity and healing including neuropathy, infection, poor glycemic control, obesity , inadequate foot care, certain immunological and inflammatory responses , age , malnutrition, smoking, High BMI , repetitive stress and pressure, certain foot conditions like onychomycosis and even iron deficiency anemia have been linked to it .

Phase II Study to Evaluate Efficacy and Safety of AMP Peptide PL-5 in Mild Infections of Diabetic Foot Ulcers

This is a Phase II, randomized, double-blind, placebo-controlled, multi-center study to evaluate the clinical efficacy and safety of Antimicrobial Peptide PL-5 Topical Spray in patients with mild infections of diabetic foot ulcers. Eligible subjects will be randomized (1:1:1) to receive twice a day, 14 days treatment of Antimicrobial Peptide PL-5 Topical Spray (1‰), Antimicrobial Peptide PL-5 Topical Spray (2‰) and topical placebo (vehicle) spray. In this study, the cut-off date for final analysis is defined as the time when all subjects have completed the last visit or discontinued the study

Wound Dressing Patch with Kelulut Honey-Infused Alginate (Tri-Gnate Alginate) for Effective Wound Care Management

The main aim of this study to effectiveness of dressing patch with Kelulut honey (Tri-Gnate Alginate) in promoting wound healing compared to conventional treatments (standard wound dressing + bactigras) and other types of medicinal honey based product (Manuka honey product). Tri-Gnate alginate is a product produced by researcher team which upgraded from raw honey into a dressing patch. 110 patients with diabetic foot ulcers is expected to enrol in this program. The patients will be assigned randomly into 3 groups namely as Group 1 - patient that will receive Tri-Gnate alginate product in their dressing, Group 2 - patient will receive Manuka honey patch product and group 3 - the patient will receive standard care (bactigras dressing + dermacyn). Prior to the applying of these dressing treatment, all the patient will receive Maggot Debridement Therapy (MDT) to ensure the wound is clean. Patient's wound condition will be monitored 7 times (T0 - T6) on alternate day basis for healing improvement.
