About this study

Official title: Clinical and Ultrasound Assessment of Efficacy of Plasma Rich Fibrin (PRF) Injection and Fractional CO2 Laser in Treatment of Postburn Hypertrophic Scars: a Randomized Controlled Clinical Trial

Recent advancements in scar management include the use of Plasma Rich Fibrin (PRF) injections and fractional CO2 laser treatments. Both modalities are considered innovative approaches that offer promising outcomes in scar revision .

Plasma Rich Fibrin (PRF) is a newer modality in regenerative medicine derived from the patient's own blood. Unlike platelet-rich plasma (PRP), PRF does not use anticoagulants during processing, leading to a natural fibrin matrix that supports prolonged release of growth factors and cytokines . This matrix has been shown to enhance wound healing and improve scar texture and appearance. Studies have demonstrated PRF's efficacy in treating various skin conditions, including acne scars and general skin rejuvenation, suggesting potential benefits for postburn scar management .

Fractional CO2 laser therapy is a well-established technique for scar treatment, including postburn scars. This technology utilizes laser energy to create microthermal zones in the skin, which stimulates collagen production and skin remodeling while minimizing damage to surrounding tissues . Clinical trials have validated the effectiveness of fractional CO2 lasers in reducing scar thickness and improving skin texture, making it a popular choice for scar revision .

Read the detailed description

Postburn scars often result in significant functional and aesthetic challenges for plastic surgeons. These scars can cause physical limitations, psychological distress, and a decrease in quality of life. Traditional treatments, including topical therapies, silicone gel sheets, and surgical interventions, frequently fall short in providing optimal results, particularly for extensive or complex scars .

Despite the individual benefits of PRF and fractional CO2 laser treatments, there is a lack of direct comparative studies assessing their relative efficacy in postburn scar management. Comparative research is essential to determine which treatment provides superior outcomes and to guide clinical decision-making .

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Clinical Assessment

    1. Clinical Assessment:

    By Vancouver Scar Scale (VSS) which consists of four items:

    1. Pigmentation (0-2) Normal 0 Hypopigmentation 1 Hyperpigmentation 2
    2. Vascularity (0-3) Normal 0 Pink 1 Red 2 Purple 3
    3. Pliability (0-5) Normal 0 Supple 1 Yielding 2 Firm 3 Banding 4 Contracture 5
    4. Height (0-3) Normal (flat) 0 0-2 mm 1 2-5 mm 2 >5 mm 3 It has a score ranging from 0-13 , The VSS set a precedent for systematic scar assessment by collecting subjective assessments and using a semiquantitative approach. 0 (best) - 13 (worst)

    Measured: 6 months

  2. Ultrasound Assessment

    Ultrasound Assessment: to detect changes in hypertrophic scar thickness before, during, and after treatment By Measurement of

    • scar thickness in millimeters

    Measured: 6 months

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 29 Oct 2024. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Mohamed Emad (+201092785198, Mohamed.16281237@med.aun.edu.eg), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Clinical Assessment (time frame: 6 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06664268, which also lists 10 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Oct 2024.
