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.\n\nIn 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.\n\nHADIF 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.\n\nThis clinical Study has been approved by local EC on 25 may 2011 (Study number 1953).\n\nTO 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.', 'detailedDescription': 'Aim of the protocol is to evaluate the effect of LDL-apheresis in combination with traditional therapy, on the recovery of diabetic ulcers in patients suffering from diabetic ischemic foot and peripheral vasculopathy that cannot be revascularized.\n\nPatients who qualify for the study will be randomized to the traditional treatment combined to apheresis (Experimental Arm) or to the standard treatment only (control Arm).\n\nThe randomization stratified according to the lesion gravity level (class TEXAS I vs II vs III),allocation 1:1. The randomization list will be generated by the statistic software "Stata 11". The lists of randomization (one list for each class TEXAS ) will be generated and will be stored by the coordinator centre. When a patient satisfies the study inclusion criteria, will be contacted the coordinator centre (by phone/mail) for group allocation.\n\n132 patients will be enrolled (66 patients in experimental arm, 66 patients in control arm).\n\nTraditional Therapy (TT) includes standard medication of ulcers, antiaggregant therapy and statins.\n\nLDL-apheresis (intervention Arm) will be performed with HELP system, for 10 session in 9 weeks.\n\nBlood samples will be collected (at basal, and after 3-6-9-12 months) in order to determine the following parameters: glycaemia, insulin, glycated haemoglobin, microalbuminuria/creatinuria,CBC, fibrinogen, total cholesterol, HDL-cholesterol, LDL-cholesterol, Triglycerides, Lp(a), C-reactive protein (CRP), pentraxin3 (PTX3).\n\nFurthermore, in patients of experimental arm, blood samples will be collected at basal and at the end of LDL-apheresis sessions no. 2 and 10 in order to determine CBC, fibrinogen, total cholesterol, HDL-cholesterol, LDL-cholesterol, Triglycerides, Lp(a), CRP, PTX3 (time schedule, after 1 and 9 weeks).\n\nThe value of the lab tests obtained at the end of apheresis will be normalized due to a possible hemodilution, according to the following formula:\n\nF dil= (1 - Htc pre-apheresis) / ( 1 - Htc post-apheresis).
