Study Description: Topical Negative Pressure Wound Therapy (TNPW) is an established tool in the management of Diabetic foot ulcer in many countries. This treatment option is under utilized in the public sector of Mauritius. This study aims to determine the efficacy of TNPW through identification of biomarkers in the Mauritian setting compared with conventional treatment~Objectives:~Primary Objective: To determine the efficacy of TNPW in the public sector in Mauritius Secondary Objectives: To compare healing times, prognostic factors skin biopsies based on biomarker, histological and genomic analysis~Endpoints:~Primary Endpoint:~Incidence of complete wound closure at 7, 14 and 21 days Time for complete wound closure Side and depth of diabetic ulcer at 7, 14, 21 days Extent of granulation tissue (Epithelialisation) (7- 21 days)~Secondary Endpoints: Hospital stay, readmission, rate of amputation and rate of infections and adverse events Number of dressing changes~Study Population: 50 patients in each arm (interventional and control) Chronic diabetic ulcers, Wagner's 2-3 Male and female Diabetes Mellitus without renal and liver impairment Age 18- 74 years Stable patients with Diabetic foot ulcer A G Jeetoo Hospital, Port-Louis and Souillac District Hospital~Phase: 2 Description of Sites/Facilities Enrolling Participants: The study will take place at the above mentioned units Approval has been received by the Regional Health Director and Consultant in Charge and the Ministry of Health and Wellness for A G Jeetoo Hospital and Souillac District Hospital.~Patients will be recruited from the Diabetes Clinic or the General Surgery Department.~Patients with chronic diabetic ulcer fulfilling the eligibility criteria Description of Study Intervention: Patients will be randomized to Negative Pressure Wound Therapy (TNPW) arm and conventional treatment arm offered at the above named hospitals. TNPW devices will be used in patients in the intervention arm for 3 weeks.~TNPW is described as a medical procedure which involves application of a dressing to the wound. The dressing is attached to a vacuum device that provides sub-atmospheric pressures which help in the removal of exudates to promote the healing process. Dressings will be changed weekly.~Study Duration: 12 months Participant Duration: Each participant will be followed weekly during the procedure then 3 monthly to assess wound healing and enquire about need for further treatment including admissions and long term adverse effects.
Topical Negative Pressure Wound Therapy (TNPW) is an established tool in the management of Diabetic foot ulcer in many countries. This treatment option is under utilized in the public sector of Mauritius. This study aims to determine the efficacy of TNPW through identification of biomarkers in the Mauritian setting compared with conventional treatment. Patient with DFU will be selected based on an eligible criteria and randomly assigned to intervention group or control group.~Primary Objective: To determine the efficacy of TNPW in the public sector in Mauritius Secondary Objectives: To compare healing times, prognostic factors skin biopsies based on biomarker, histological and genomic analysis A randomised controlled study is being proposed, where up to 100 participants will be recruited.~The wounds of participants in the intervention arm will be managed with 3 weeks of TNPW.
