Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goals of this series of studies is to test the effect of RIC on chronic leg ulcers (Diabetic ulcers and venous ulcers) - and to improve the understanding of its biological mechanism. This is a prospective, double-blind, randomized, shame procedure-controlled study.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

After getting patients informed consent. Initial evaluation that includes: Venous and Arterial vascular evaluation, Medical past History including medications and surgeries Documentation of the chronic wounds by description and photography with scale.

Base line blood test for CBC, HbA1C, Electrolytes, Urea, Cr, Liver enzymes. IL 1 IL 6 VEGF NO CD34 Adenosine All patients will received the standard wound care in use by the staff of the chronic wound clinic. Care givers will be blinded as to the study allocation of each patient. Patients will be divided randomly into two equal groups. Pressure cuffs will be applied to both arms of all subjects. The cuffs will be inflated and deflated intermittently for three cycles of 5 minutes each. In the study group, the cuffs will be inflated to 50 mmHg above systolic blood pressure while the performing investigator examines the radial pulse to ensure complete blood flow obstruction. In the control group, inflation will be up to 10 mmHg only. The patients will be followed for 10 weeks.

During this period, they will be examined every 2 weeks (5 follow-up visits); and in each of these visits the above procedure will be repeated including blood collection before intervention and 24-48h after intervention.

In each visit a "blinded" physician will photograph with scale the wound and grade the granulation tissue covering the wound on a scale from 0 to 5.

The primary end point of the study is the number of healed wounds and wound area change among the two groups. Secondary outcomes will be the degree of granulation tissue and levels of IL 1 IL 6 VEGF NO CD34 Adenosine

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

RIC

In the study group, a blood pressure cuff will be inflated to 50 mmHg above systolic blood pressure while the performing investigator examines the radial pulse to ensure complete blood flow obstruction. Ischemia will be performed for 3 cycles of 5 min each and 10 min resting between cycles.

Group Type EXPERIMENTAL

Remote Ischemic Conditioning

Intervention Type PROCEDURE

Creation of Brief 5 min Ischemia to upper limb using a Blood pressure cuff

Control

In the control group, a blood pressure cuff will be inflated to 10 mmHg (Sham procedure) for 3 cycles of 5 min each and 10 min resting between cycles.

Group Type SHAM_COMPARATOR

Control

Intervention Type OTHER
