Summary

Diabetic foot (DF) is a common, severe and costly complication of diabetes. DF is underlied by neuropathy, atherosclerosis of distal arteries and infection, which result in tissue ulcers and necrosis. Alterations in microcirculatory function and in blood rheology may concur in causing tissue damage.

In recent years there has been accumulating evidence that LDL apheresis (LA) does not only reduce cholesterol but also has a series of pleiotropic effects that improve the microcirculation, increasing peripheral tissue perfusion.

HADIF is a randomized, multicentric, prospective clinical study aimed at assessing the effect of LDL apheresis treatment in association with traditional therapy for ulcers, in patients with an ischemic diabetic foot ulcer (class I and II Texas Wound Classification System)and peripheral vasculopathy not susceptible to revascularization. A total of 132 patients will be enrolled. Participants will be centrally randomized to receive traditional therapy alone (TT) or in association with LA. TT includes standard medication of ulcers, antiaggregant therapy and statins. LA will be performed with HELP system, for a total of 10 sessions in 9 weeks. The primary end-point of the study is ulcer healing; secondary endpoints include improvements of peripheral oxygenation, resolution of pain, reduction of circulating inflammatory markers, cardiovascular events during one year's follow-up.

This clinical Study has been approved by local EC on 25 may 2011 (Study number 1953).

TO BE NOTED: since diabetic patients in our "Diabetic-Foot UNIT" often presented foot ulcers more severe than class II Texas, a formal amendment has been submitted to EC for recruiting patients with diabetic foot ulcer of class III Texas. The amendment was already approved on 5 may 2012.

DEVICE

LDL-apheresis

The patient of the Arm "LDL-apheresis" in addition to standard therapy, will undergo a cycle of LDL-apheresis. LDL-apheresis will be performed with B.Braun Avitum H.E.L.P. System. Apheretic treatment scheme: 10 apheretic sessions carried out as follows: the first 2 with a 3 day distance (i.e. 2 treatments in one week), successively 1 session per week (every 7 days). To perform the treatment, the forearm surface veins will be punctured by means of 17 Ga needles, as an alternative a two-ways CVC will be used.
