Clinical Trial Summary

This pilot study examined the effects of ELO water, a commercially-available oxygen-enriched drinking water, on wound healing in patients with diabetic foot ulcers over 12 weeks.


Description:

As hyperbaric chamber and topical oxygen therapies have demonstrated efficacy in improving DFU healing, the aim of this study was to evaluate ELO water, which has been shown to increase arterial oxygen levels, as a novel means of increasing oxygen delivery to poorly-healing DFUs as an adjunct to standard care. This proof-of-concept pilot study of drinking oxygen-enriched ELO water to treat diabetic foot ulcers (DFUs) was conducted on 16 adults with non-healing (for at least 30 days prior to the study) DFUs in Changi General Hospital in Singapore. ELO water was delivered to participants' homes and their water consumption recorded in diaries, which was checked by the research co-ordinator at 2-weekly visits for 12 weeks. Minimum compliance was defined to be at least 85% of the water (12/14 bottles/fortnight), equivalent to 9 litres/week. No changes in diabetic therapy, diet or exercise were made during the study period. All participants were seen by podiatrist for standard of care DFU treatment weekly. The ulcer size was captured following wound debridement each week using a standardized digital photographic protocol and the photos were encrypted and anonymized for confidentiality and data protection. All the images were assessed independently. Wound dressing was carried out twice per week in between visits at primary care clinics or at home.
