Brief Summary:
using platelet-rich plasma (PRP) in healing diabetic foot ulcers (DFUs), and to compare the rate of healing and final outcome with conventional therapy.

Condition or disease Intervention/treatment
Diabetic Foot Ulcer Other: 20-100 ml venous blood will be drawn the from patient into sterilized centrifuge tube ,following centrifuge to separate PRP and at the bed side and tricked onto the ulcer twice weekly Other: standard treatment

Detailed Description:

Diabetic foot ulcers (DFU) are one of the most frequent and difficult complications in diabetes. The risk for a diabetic patient to develop an ulcer during his life is estimated as being 25%. Ulcers are a frequent cause of lower limbs amputation and 84% of lower limb amputations are preceded by ulcers .

Diabetic ulcer (DU) is not only a serious clinical problem with negative impacts on both the life quality and survival time, but also an economic burden with significant contribution to high cost and lengthy hospitalizations. Furthermore, the non healing diabetic cutaneous ulcers along with the subsequent amputations may bring about costly to treat and painful disabilities. However, healing of the DU may be improved and most of the amputations may be prevented by more effective treatments based on diabetic education .

In spite of the high prevalence and morbidity associated with DFUs, current treatment options are limited. Current standard management consists of surgical debridement followed by frequent dressing changes with tight infection and glycemic control. Despite this comprehensive approach, complication and amputation rates remain high.

The use of platelet-rich plasma (PRP) has emerged as an adjunctive method for treating DFUs.

Platelet-rich plasma (PRP) preparations were first described in the 1980s as plasma with a platelet count above that found normally in peripheral blood.

First used in the field of hematology, PRP use has expanded throughout the fields of dermatology, oral-maxillofacial surgery, plastic surgery, cardiac surgery, ophthalmology, urology, and gynecology .

The concentration of platelets in PRP is 2-6 folds higher than that of whole blood .

The curative properties of PRP rely on the fact that platelets are a physiological reservoir of a variety of growth factors, with healing function which have an active role in tissue regeneration .

Platelets contain proteins, known as growth factors that trigger biological effects including directed cell migration (i.e. chemotaxis), angiogenesis, cell proliferation and differentiation, which are key elements in the process of tissue repair and regeneration.

Specifically, the platelet alpha-granules contain several of these molecules, including: platelet derived growth factor (PDGF),transforming growth factor B ( TGF-β), vascular endothelial growth factor (VEGF), epithelial growth factor (EGF), fibrinogen, fibronectin, and vitronectin.

In addition, platelet delta granules contain serotonin, histamine, dopamine, calcium, and adenosine, which act in tandem with the aforementioned growth factors to regulate wound healing .

platelets exert antimicrobial activity against some bacteria of the skin, and clinical data shows that the presence of infection is reduced in PRP-treated wounds.

The advantages and merits of PRP are apparent since it is easy, cost-effective and much more lasting compared to other standard treatments and being autologous in nature, it is free from communicable pathogens, making it a safe treatment modality with good clinical results

Group/Cohort Intervention/treatment
study group
in this group the investigators will be managing diabetic wounds with platelet rich plasma treatment.
Other: 20-100 ml venous blood will be drawn the from patient into sterilized centrifuge tube ,following centrifuge to separate PRP and at the bed side and tricked onto the ulcer twice weekly
topical application of platelets rich plasma after Centrifugation at diabetic foot ulcer to study group ,history taking . Ankle brachial index (ABI) measuring and laboratory testes including hemoglobin A1c ( HgA1)c,cbc and prothrombin time( pt) and prothrombin concentration ( pc)

control group
In this group patients will receive the standard treatment in form of debridement and dressing twice weekly
Other: standard treatment
Subjects in the control group will receive Standard Wound Care treatment for chronic ulcers according to accepted medical practices.

Primary Outcome Measures :
  1. Change of ulcer size [ Time Frame: 16 weeks ]
    ulcer size will be measured with ruler/probe for length, width and depth and estimated by calculating the ulcer size in centimeter (cm 2).

Secondary Outcome Measures :
  1. time of wound healing [ Time Frame: 16 weeks ]
    Complete wound closure over period of 16 weeks
