High Transepidermal Water Loss Predicts Diabetic Foot Ulcer Recurrence, reveals study
A study published in Diabetes Care has found that transepidermal water loss (TEWL) is a strong predictor of diabetic foot ulcer recurrence. Involving over 400 adults, the study revealed that individuals with high TEWL were 2.7 times more likely to experience ulcer recurrence compared to those with low TEWL.
A research team funded by the National Institutes of Health (NIH) has identified a diagnostic aid that has the potential to accurately predict the recurrence of diabetic foot ulcers that appear to be fully healed. By measuring the skin’s barrier function through a process known as trans-epidermal water loss, or TEWL, scientists were able to determine which wounds were more likely to reopen. TEWL measurements are a major factor in burn care, where deep layers of the skin are often damaged. The findings suggest that full restoration of skin barrier function should be incorporated into existing wound treatment standards to ensure complete wound closure and to better identify patients at risk of wound recurrence.
“This study is an important initial step to give clinicians treating diabetic foot ulcers a reliable diagnostic aid for the first time to assess an individual’s risk of ulcer recurrence,” said Teresa Jones, M.D. program director for the Division of Diabetes, Endocrinology, & Metabolic Diseases at NIH’s National Institute of Diabetes, Digestive and Kidney Diseases (NIDDK). “Foot ulcers are such a confounding issue with diabetes and being able to determine which wounds are at highest risk for recurrence could save many lives and limbs.”
