About this study

Official title: Regenerative Effects of Human Stem Cell Media After Laser Therapy in Hypertrophic Scar Caused by Burns

The purpose of this study was to determine the effect of combined treatment using nonablative laser and human stem cell media (HSCM) on the regeneration of hypertrophic scars that occurred after burns.

Read the detailed description

The purpose of this study was to determine the effect of combined treatment using nonablative laser and human stem cell media (HSCM) on the regeneration of hypertrophic scars that occurred after burns. Nonablative laser treatment was performed on 30 patients with hypertrophic scars on both sides of the same part of the body. Immediately after the laser treatment, the hypertrophic scars of right side to which HSCM was applied and the left side with the same body position were defined as a control scar, and normal saline was applied. Over the next 6 days, HSCM and moisturizer were applied on the scars of right side, and only moisturizer was applied on the control scar of left side. Laser treatment was performed three times on the hypertrophic scar at 4 weeks intervals. The skin test on hypertrophic scar was evaluated before laser treatment and re-evaluated on the 7the day after the 3rd laser treatment. The thickness was measured with a ultrasonic wave equipment (128 BW1 Medison, Korea). Mexameter® (MX18, Courage-Khazaka Electronics GmbH, Germany) was used to measure melanin levels and the severity of erythema. The higher values indicating a darker and redder skin. Transepidermal water loss (TEWL) was measured with a Tewameter® (Courage-Khazaka Electronic GmbH, Germany), which is used for evaluating water evaporation. Sebum in the scars was measured with the Sebumeter® (Courage-Khazaka Electronic GmbH, Germany). The measurement is based on the principle of grease-spot photometry using a cassette with its special tape. A microprocessor calculates the result, which is shown on the display in μg/cm2. Elasticity was measured using Cutometer SEM 580® (Courage-Khazaka Electronic GmbH, Cologne, Germany), which applies negative pressure (450 mbar) on the skin. The numeric values (mm) of the skin's distortion is presented as the elasticity (Table 1). Two seconds of negative pressure of 450 mbar is followed by 2 s of recess, and this consists of a complete cycle. Three measurement cycles were conducted, and the average values were obtained. To evaluate the effect of HSCM, investigators compared the skin test results (thickness, melanin, erythema, TEWL, sebum, and skin elasticity levels) between the right side and control side, from baseline measures immediately before the laser treatment and measures on the 7the day after the 3rd laser treatment. Outcome measurements and data analyses were performed by a trained and blinded outcome assessor who was not involved in the intervention. Possible complications (pain, ecchymosis, skin abrasion, and swelling) were observed.

What is being measured

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

  1. scar thickness (cm)

    The thickness was measured with a ultrasonic wave equipment

    Measured: baseline

  2. change from baseline scar thickness at 3 months (cm)

    the change of scar thickness was measured with a ultrasonic wave equipment

    Measured: after 3 months intervention

Secondary outcomes (8)
  1. melanin levels (arbitraty units; AU)

    the higher values indicating a darker

    Measured: baseline

  2. change from baseline melanin level at 3 months (arbitraty units; AU)

    the higher values indicating a darker

    Measured: after 3 months intervention

  3. erythema level (arbitraty units; AU)

    the higher values indicating a redder skin

    Measured: baseline

  4. change from baseline erythema level at 3 months (arbitraty units; AU)

    the higher values indicating a redder skin

    Measured: after 3 months intervention

  5. transepidermal water loss (g/h/m2)

    the higher the number, the more dry the skin is.

    Measured: baseline

  6. change from baseline transepidermal water loss at 3 months (g/h/m2)

    the higher the number, the more dry the skin is.

    Measured: after 3 months intervention

  7. Sebum level (μg sebum/cm2)

    A microprocessor calculates the result, which is shown on the display in μg/cm2. The higher the number, the more oily the skin is.

    Measured: baseline

  8. change from baseline sebum level at 3 months (μg sebum/cm2)

    A microprocessor calculates the result, which is shown on the display in μg/cm2. The higher the number, the more oily the skin is.

    Measured: after 3 months intervention
