Brief Summary:

As atrophic striae are common dermatological conditions. Various therapeutic modalities have been employed in the treatment of striae distensae, mainly in striae rubra. There are few studies that include the treatment of striae alba.

The non-ablative fractionated laser and, more recently, microneedling are two distinct treatments, but they are widely used in dermatologist practice.

The present randomized clinical trial is aimed at evaluating and evaluating the response of microneedle and fractional non-ablative laser Nd-yap 1340 in the treatment of abdominal striae alba.


Condition or disease Intervention/treatment Phase
Striae Distensae Device: Nd-Yap 1340nm laser Device: Microneedling Not Applicable

Detailed Description:
Twenty patients will be treated at the dermatologic clinic of the Hospital de Clínicas de Porto Alegre (HCPA). Each patient will be treated with laser and microneedle at the same time, being applied a therapeutic procedure in each part of the abdomen (divided lengthwise and in equal parts). Each part of the abdomen will be randomized for the treatment of laser or microneedling with the help of the Excel 2013 program. The investigator responsible for procedures and patients are the only ones with unblinded assessment in relation to the side of each treatment. There will be 5 sessions with monthly intervals of the proposed treatments. The ND-yap 1340-nm laser will be used, and in the other segment of the abdomen, the dermaroller 2.5 mm was applied. Photographic records of patients will be performed at pre-treatment and 1 month after the third and fifth sessions. The questionnaires will be applied to assess the quality of life in dermatology DLQI (Dermatology Life Quality Index). Two independent and blind evaluators for the type of treatment will apply in the Global Aesthetic Scale (GAIS) in the evaluation of photographic records. Cutaneous biopsies for histopathological evaluation will be performed with a punch 3 mm of each part of the abdomen at pretreatment. Two experienced pathologists will evaluate the measurements of the epidermis and the collagen and elastic fibers of the skin.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 20 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description: Each patient will have the abdomen divided equally. Each segment of the abdomen will be randomized using the Excel 2013 program to receive laser or microneedle treatment.
Masking: Double (Investigator, Outcomes Assessor)
Masking Description:

Clinical evaluators will evaluate the photos after the treatments blindly for which type of treatment applied.

Evaluators of skin biopsies will be blinded to what type of treatment is applied and for pre-treatment and post-treatment.

Arm Intervention/treatment
Active Comparator: Nd-Yap 1340nm laser
The randomly assigned segment of the abdomen will receive 5 sessions with monthly intervals of Nd-yap 1340nm laser.
Device: Nd-Yap 1340nm laser
Each part of the abdomen will be treated with a therapeutic modality. The ND-yap 1340-nm laser will be used in the following parameters: 90 mtz / cm2 nozzle, 90 mJ / mtz power, 2.5 Hz frequency, 3 ms pulse duration, 1 pass.
Other Name: Nonablative Fractional Laser

Experimental: Microneedling
The randomly assigned segment of the abdomen will receive 5 sessions with monthly intervals of dermaroller 2,5mm.
Device: Microneedling
In the other segment of the abdomen, the dermaroller 2.5 mm will be applied, with ten to fifteen passes in the same direction and at least four crosses in the rolling areas.
Other Names:
  • Dermaroller
  • Percutaneous Collagen Induction Therapy




Primary Outcome Measures :
  1. Clinical response in abdominal alba striae after the therapies [ Time Frame: 6 months ]
    Clinical response to microneedle treatment and nonablative fractional laser treatment without abdominal alba striae (GAIS scale). The GAIS scale is a non-numerical scale divided into 5 categories of clinical response: very much improved, much improved, improved, no changed and worse.


Secondary Outcome Measures :
  1. Clinical response to microneedle treatment and nonablative fractional laser treatment [ Time Frame: 4 months ]
    Clinical response to microneedle treatment and nonablative fractional laser treatment without abdominal alba striae (GAIS scale). The GAIS scale is a non-numerical scale divided into 5 categories of clinical response: very much improved, much improved, improved, not changed and worse.

  2. Histopatological response in abdominal striae alba after the therapies [ Time Frame: 4 months ]
    Histopathological evaluation of the thickness of the epidermis, as collagen and elastic (picrosirius stain, orcein stain)

  3. Histopatological response in abdominal striae alba after the therapies [ Time Frame: 6 months ]
    Histopathological evaluation of the thickness of the epidermis, as collagen and elastic (picrosirius stain, orcein stain)

  4. The tolerability and incidence of adverse effects during the therapies [ Time Frame: 1 month ]
    To assess the tolerability and the incidence of immediate and late adverse effects (pain, skin erythema, pruritus) for both techniques

  9. The impact on the quality of life provided by the striae distensae [ Time Frame: Pre-treatment (first day of the evaluation) ]

    To evaluate the impact on the quality of life (DLQI) provided by the striae. It is a simple 10-question validated questionnaire that has been used in over 40 different skin conditions.The DLQI is the most frequently used instrument in studies of randomised controlled trials in dermatology.

    The DLQI is calculated by summing the score of each question resulting in a maximum of 30 and a minimum of 0. The higher the score, the more quality of life is impaired.

    0-1: no effect at all on patient's life 2-5: small effect on patient's life 6-10: moderate effect on patient's life 11-20: very large effect on patient's life 21-30:extremely large effect on patient's life
