Hair Cycle Modulation To Promote Human Wound Healing

- Registration Number
- NCT04753060
- Lead Sponsor
- University of Hull
- Brief Summary
Chronic wounds represent a huge burden to both patients and the National Health Service (NHS), with over 200,000 sufferers in the UK alone. Based on current conservative estimates the NHS spends £2.3 - £3.1 billion pounds every year treating these patients.
This study aims to reduce this shared burden, preliminary data from our research group using animal models has demonstrated variable ability of hair follicles to heal wounds based upon their stage within their growth cycle. This currently proposed study therefore aims to perform a simple novel intervention on patients prior to their elective surgery in an effort to replicate the substantial healing abilities noted in the animal models.
Under normal circumstances, a patient's operative site is shaved prior to the surgery for hygiene and visual simplicity. The aim of this study is to wax 50% of the patient's operative site prior to their surgery, the other half will be shaved on the day of surgery as per normal surgical protocol. Based on known data this waxing technique will cycle the hair follicles into their growth phase at the time of surgery. The growth phase of hair follicles corresponds with an increased ability to heal due to recruitment of a patients own stem cells. This study therefore aims to take advantage of the patient's own stem cell population. The 50% waxing and 50% shaving method upon each patients donor site allows us to directly compare the influence of these two methods directly on a patient-by-patient basis.

- Primary Outcome Measures
Name Time Method Photograph Assessment 3 months post-surgery Digital assessment of healing outcome from clinical wound photographs using novel scale (1-10). Higher score is representative of a better outcome.
- Secondary Outcome Measures
Name Time Method Changes To Patient Microbiome (Next-Generation Sequencing) 0, 7, 14 days and 3 months. Changes to skin microbiome as compared to day 0 using next-generation sequencing.
Post Operative Infection incidence 3 months post surgery Clinical assessment reports a presence or absence of infection
Histological Wound Healing Score 3 months post surgery H\&E stained histological sections will be used to quantify healing using a study-specific scale (1-10). Higher score is representative of an improved outcome.
Identification of Hair Cycle State via Histology 14 days post surgery Tissue biopsies will be analysed histologically to identify the presence of anagen and telogen hair follicles.
