당뇨병 환자의 피부궤양 상처치유에 대한 개인별 영양중재의 평가

당뇨병 환자의 피부궤양 재생능력 및 상처치유에 대한 MSC 유래 엑소좀의 적용과 함께 개인별 맞춤 영양중재 평가 원문보기 KCI 원문보기 인용

The ageing population and the increase in diabetes raise the prevalence of chronic skin ulcers (CCU). In diabetics, precursor cell mobilization decreases. In wounds, the inflammation is prolonged and oxidative stress increases. This is an unfavorable microenvironment for healing. A major risk factor in the development of CCU is nutritional deficiency. Healing needs energy and nutrients for regeneration. In diabetics the malnutrition can be more than 60%. However, although the provision of certain nutrients can improve the healing capacity, it is not a common clinical practice to nutritionally evaluate diabetic with CCU. Exosomes are extracellular vesicles that reflect the physiological state of the cells producing them. Stem cell derivatives exosomes are rich in factors, that can provide a favorable microenvironment for tissue regeneration.

The aim of this project is to develop a therapeutic process to accelerate the healing of diabetic CCU, based on the correction of nutritional deficiencies, to improve the regenerative capacity, together with the application of exosomes from mesenchymal stem-cell (MSC) in the wound, creating a microenvironment that favors tissue regeneration. For this, a pilot clinical trial with diabetic patients with CCU is proposed, to evaluate the effect of personalized nutritional supplementation on healing and regenerative capacity.

실험적: Nutritional Intervention (NI)

In addition to the usual treatment, will receive dietary advice and a nutritional supplement, according to the results of their evaluation in the Endocrinology Service

Those with malnutrition criteria will also receive a nutritional supplement (e.g. fortimel cubitan, advanced or extra, Nutricia) or another of similar composition, in case of intolerance to the first option. The aim will be to provide at least 50% of the recommended intakes for the main nutrients related to wound healing.

간섭 없음: Control (C)

Who will continue with their usual treatments in the Diabetic Foot Unit and they will receive dietary advice
