PRP or the Leucocyte-Platelet-Fibrin Patch for a Diabetic Foot Ulcer: What IWGDF 2023 Supports

Platelet-rich plasma (PRP) is a second-line option for a clean, non-infected diabetic foot ulcer with good blood supply that has stalled despite 4 to 6 weeks of standard care. The IWGDF 2023 guideline specifically supports the autologous leucocyte, platelet and fibrin patch, while evidence for ordinary PRP gels and injections remains weaker.

PRP for diabetic foot ulcer treatment may be considered when a wound has not improved despite appropriate standard care. However, ordinary platelet-rich plasma (PRP) and the autologous leucocyte-platelet-fibrin patch are not identical treatments. The IWGDF 2023 guideline conditionally supports the latter for selected difficult-to-heal ulcers, while evidence for other PRP preparations remains less certain.

Key Takeaways

• Platelet-rich plasma uses concentrated components of a patient's blood to support tissue repair.

• Ordinary PRP gels or injections differ from the autologous leucocyte-platelet-fibrin patch.

• The IWGDF 2023 guideline conditionally recommends considering the autologous leucocyte-platelet-fibrin patch as an adjunct for diabetic foot ulcers that fail to heal with standard care.

• PRP-based treatments cannot replace infection control, pressure offloading, debridement or vascular assessment.

• Wound suitability depends on infection, blood supply, platelet count, previous treatment and the wound's healing progress.

• A treatment plan should include measurable goals, reassessment dates and clear criteria for changing treatment.

What Is PRP for a Diabetic Foot Ulcer?

Platelet-rich plasma, commonly called PRP, is prepared from a patient's blood.

Blood is collected and processed to concentrate platelets, which contain growth factors involved in normal tissue repair.

These growth factors participate in processes such as cell signalling, tissue formation and wound healing.

The concept behind platelet rich plasma wound healing is to deliver concentrated platelet-derived components to a wound that is not progressing as expected.

However, PRP is not a single standardized product.

Different preparation systems can produce materials with different platelet concentrations, white blood cell content, fibrin structures and methods of application.

Some preparations are applied as gels, while others are used as injections or wound dressings.

These differences matter when interpreting research results.

Evidence supporting one platelet-based preparation should not automatically be applied to every PRP treatment offered for diabetic foot ulcers.

What Is the Difference Between PRP and a Leucocyte-Platelet-Fibrin Patch?

The distinction is particularly important because the IWGDF 2023 guideline addresses a specific type of platelet-based treatment.

An autologous leucocyte-platelet-fibrin patch is prepared from the patient's own blood and contains leucocytes, platelets and a fibrin matrix.

The fibrin structure forms a patch that can be placed directly onto an appropriately prepared wound.

Ordinary PRP preparations may not contain the same cellular components or fibrin structure.

The term LeucoPatch diabetic foot treatment is commonly used when discussing the autologous leucocyte-platelet-fibrin patch studied in clinical research.

Patients should therefore ask which exact product or preparation is being offered rather than assuming all PRP treatments have the same evidence.

What Does IWGDF 2023 Actually Recommend?

The International Working Group on the Diabetic Foot (IWGDF) publishes evidence-based guidance on diabetic foot management.

Its 2023 wound-healing guideline suggests considering autologous leucocyte, platelet and fibrin patches as an adjunctive treatment for diabetes-related foot ulcers when standard care alone has failed.

This is a conditional recommendation supported by evidence judged to have limitations.

It does not mean that every diabetic foot ulcer should receive PRP or a fibrin patch.

It also does not establish that ordinary PRP injections, gels and other platelet preparations provide equivalent outcomes.

The term adjunctive is essential.

It means the treatment is added to appropriate wound care rather than replacing it.

Patients can learn about the broader range of advanced wound therapies considered in diabetic foot management.

What Did the LeucoPatch Clinical Trial Show?

An important study was the randomized clinical trial published by Game and colleagues in The Lancet Diabetes & Endocrinology in 2018.

The study investigated an autologous leucocyte-platelet-fibrin patch in patients with difficult-to-heal diabetic foot ulcers.

The treatment group had a higher proportion of ulcers achieving complete healing during the study period than the standard-care group.

This provided evidence that the patch could offer additional benefit in appropriately selected patients.

However, the findings should not be interpreted as proof that every platelet-based treatment produces the same results.

The trial evaluated a particular preparation and treatment protocol.

Real-world outcomes may differ according to wound characteristics, circulation, infection, pressure management and patient health.

Which Diabetic Foot Ulcers May Be Suitable for PRP-Based Treatment?

The first step is to establish why the ulcer is not healing.

A chronic diabetic foot ulcer may be affected by several factors, including repeated pressure, neuropathy, infection, inadequate blood supply, necrotic tissue and abnormal foot mechanics.

Before considering a platelet-based adjunct, the treating team should assess whether these problems have been adequately addressed.

A diabetic foot ulcer that remains open despite appropriate care may need reassessment of the diagnosis and treatment plan.

Selected difficult-to-heal ulcers may then be considered for advanced wound treatment.

Suitability depends on the specific preparation, clinical findings and treatment protocol.

This checklist supports clinical decision-making but does not establish eligibility by itself.

The exact requirements depend on the product and treatment protocol.

Why Must Infection Be Controlled Before PRP Treatment?

An infected diabetic foot ulcer requires appropriate infection assessment and management.

A platelet-based patch should not be used as a substitute for antibiotics when indicated, drainage of an abscess, debridement or other necessary treatment.

Signs that may suggest infection include increasing redness, warmth, swelling, purulent discharge and worsening tissue damage.

In patients with neuropathy, severe pain may be absent even when infection is significant.

If deeper infection or osteomyelitis is suspected, additional investigations and treatment may be required.

A PRP for non healing wound plan should therefore begin by confirming that untreated infection is not the main reason the ulcer remains open.

Why Is Blood Supply Important Before PRP?

Wound healing depends on adequate circulation.

Blood delivers oxygen, nutrients and immune cells required for tissue repair.

If significant peripheral arterial disease is present, applying a platelet-based treatment cannot replace the need to assess arterial blood supply.

Depending on the clinical findings, vascular assessment may include pedal pulse examination, Doppler testing, toe-pressure measurements or transcutaneous oxygen pressure (TcPO2).

These investigations can help determine whether poor perfusion is contributing to the wound's failure to heal.

When clinically indicated, vascular intervention may need to be considered.

Why Standard Wound Care Must Continue

Advanced wound treatments work best when the underlying wound-management principles are followed.

Appropriate standard wound care may include wound cleaning, debridement when indicated, appropriate dressings, infection management and regular monitoring.

For plantar diabetic foot ulcers, effective offloading is especially important.

A patient who continues walking on an inadequately protected wound may repeatedly damage newly forming tissue.

This can limit healing regardless of which advanced dressing is applied.

Therefore, a platelet-based treatment should never be presented as a replacement for pressure relief or other essential care.

PRP for Diabetic Foot Ulcer in Vizianagaram: Who Should Consider Specialist Assessment?

Patients considering prp for diabetic foot ulcer in vizianagaram should first have the wound assessed to determine why healing has stalled.

A specialist review may be appropriate when an ulcer has shown limited improvement despite several weeks of suitable wound care, pressure relief and management of other contributing factors.

The assessment should include wound characteristics, infection status, blood supply, diabetes control and relevant medical history.

At Elegance Diabetic Foot & Ulcer Clinic (EDFC), Dr. Ashutosh Shah, Consultant Plastic, Reconstructive & Diabetic Foot Surgeon, evaluates difficult-to-heal diabetic foot wounds and the possible role of advanced treatment.

The decision should be based on clinical suitability rather than choosing PRP solely because the wound has been present for a long time.

How Is a Leucocyte-Platelet-Fibrin Patch Prepared?

An autologous leucocyte-platelet-fibrin patch is prepared using the patient's own blood.

The preparation process depends on the specific system being used.

Generally, blood is collected and processed under controlled conditions to produce a patch containing platelets, leucocytes and fibrin.

The patch is then applied to an appropriately prepared wound according to the treatment protocol.

The clinician continues the required wound dressing, pressure management and follow-up.

Because the material comes from the patient's blood, blood count and other clinical factors may influence suitability.

Patients should ask which preparation system is being used and whether the clinic follows a standardized protocol.

How Many PRP Sessions Are Needed for a Diabetic Foot Ulcer?

There is no universal number of sessions suitable for every diabetic foot ulcer.

Treatment frequency depends on the specific preparation, wound characteristics, protocol and clinical response.

A structured treatment plan should specify how often the wound will be reviewed and when progress will be measured.

Some protocols involve repeated applications, but patients should not be promised that a wound will heal after a fixed number of sessions.

The objective is measurable healing progress rather than simply completing a package.

How Is Wound Healing Progress Measured?

Wound measurements help determine whether treatment is producing meaningful improvement.

Clinicians may record wound length, width, depth where appropriate, tissue appearance, discharge and surrounding skin condition.

Photographs can support documentation when taken consistently and with patient consent.

At EDFC, weekly wound measurements can help assess whether an advanced wound treatment is supporting healing.

The treating team should also review infection, circulation, offloading and glucose control.

A reduction in wound area can indicate progress, but the wound's overall condition remains important.

What Is the Four-Week Reassessment Rule?

If an ulcer does not show meaningful improvement after approximately four weeks of an adjunctive treatment, the clinical team should reassess the plan.

This does not mean every wound must be completely healed within four weeks.

Instead, it means the clinician should determine whether the current treatment is making sufficient progress to justify continuing it.

The reassessment may consider:

• Whether pressure is adequately controlled

• Whether infection has developed or persisted

• Whether blood supply is sufficient

• Whether the wound needs further debridement

• Whether the selected advanced therapy is appropriate

• Whether another treatment strategy is required

The decision to continue or stop treatment should be individualized rather than based solely on a fixed number of applications.

Is PRP Safe for Everyone?

No medical procedure is suitable for every patient.

Autologous platelet-based treatment involves blood collection and processing, so the patient's blood count, general health and other clinical factors may need review.

Patients with low platelet counts, significant blood disorders or other relevant conditions may require additional evaluation.

The proposed treatment also needs to be considered in relation to wound infection, circulation and overall medical status.

Relevant laboratory tests can help clinicians understand the patient's condition before deciding whether a platelet-based procedure is appropriate.

The exact safety requirements depend on the preparation method and treatment protocol.

How Much Does PRP for a Diabetic Foot Ulcer Cost?

The PRP cost for wound in India varies according to the preparation system, facility, number of applications and associated wound-care requirements.

A single application price may not represent the full cost of treatment.

Patients should ask whether the quoted amount includes wound assessment, blood processing, dressing materials, follow-up visits and any additional investigations.

They should also clarify whether the proposed treatment is ordinary PRP or a leucocyte-platelet-fibrin patch.

Cost comparisons are meaningful only when the treatments being compared are clinically similar.

The most expensive treatment is not automatically the most effective.

What Should the Treatment Plan State Before PRP Begins?

Before starting an advanced platelet-based treatment, the patient should understand why it is being recommended.

A clear treatment plan should explain the wound diagnosis, what standard treatment has already been provided, which PRP or patch preparation is proposed and what evidence supports its use.

It should also identify the expected review schedule and how progress will be measured.

Patients should know what will happen if the wound does not improve.

There should be no guarantee of complete healing after a predetermined number of applications.

Conclusion

PRP for diabetic foot ulcer treatment should be understood as a possible adjunct rather than a replacement for comprehensive wound care.

The IWGDF 2023 guideline specifically supports considering an autologous leucocyte-platelet-fibrin patch for selected difficult-to-heal diabetic foot ulcers, while evidence for other PRP preparations cannot automatically be treated as equivalent.

Successful diabetic foot ulcer management still depends on identifying and treating the factors preventing healing, including infection, repeated pressure, poor circulation and deeper tissue problems.

At Elegance Diabetic Foot & Ulcer Clinic (EDFC), Dr. Ashutosh Shah and the clinical team assess wound characteristics and previous treatment before considering advanced wound therapies.

The most important principle is to select treatment based on the individual wound, monitor progress objectively and reassess when healing is not occurring as expected.
