Long-pulsed 1064 nm Nd-YAG Laser Versus TCA 20% in Treatment of Keratosis Pilaris

August 1, 2021 updated by: Dina Saadi, Cairo University

Clinical and Dermoscopic Evaluation of Long-pulsed 1064 nm Nd-YAG Laser Versus Trichloroacetic Acid 20% in Treatment of Keratosis Pilaris

Keratosis pilaris (KP) is a common disorder of keratinization. There are different treatment modalities for KP with variable results. Nd:YAG laser and chemical peels are among these treatment modalities, however, there is no enough evidence in the literature regarding their efficacy. The aim of this study is to assess and compare the efficacy of long pulsed Nd:YAG laser and trichloreacetic acid 20% in treatment of keratosis pilaris.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Keratosis pilaris (KP) is a genetic disorder of keratinization of hair follicles of skin. It's a very common benign condition that manifests as small, rough folliculocentric keratotic papules, often described as chicken bumps, chicken skin or goose-bumps, in characteristic areas of body, particularly the outer upper arms and thighs.

Trichloreacetic acid (TCA) is a type of chemical peels that is derived from acetic acid by the chlorination of 3 hydrogen ions. It can induce coagulative necrosis of proteins and cells. The depth of action depends on various factors e.g the number of layers applied and its combination with substances that potentiate its action.

Nd: YAG laser is a type of hair removing devices that operates at wave length of 1064nm. This wave length allows for less absorption at the epidermis. It is less absorbed by melanin, which leads to lower side effect and better tolerance but less efficacy in dark skinned patients.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 60 years (Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Female

Description

Inclusion Criteria:

  • Patients above 18 years with KP.
  • Patients with KP affecting back of the trunk, arms, thighs, forearms, legs and buttocks.

Exclusion Criteria:

  • Pregnant or lactating females.
  • Patients who had performed any laser treatment for KP within 6 months prior to the study.
  • Patients with history of oral retinoids within 3 months prior to the study.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change of clinical and dermoscopic scores of KP with Nd-YAG laser
Time Frame: 4 months
the change in roughness and color of KP by clinical score after 4 sessions of Nd-YAG laser. the score ranges from 0-4. where 0 is no change and 4 is excellent improvement
4 months
Change of clinical and dermoscopic scores of KP with TCA 20%
Time Frame: 4 months
the change in roughness and color of KP by clinical score after 4 sessions of TCA 20% peel. the score ranges from 0-4. where 0 is no change and 4 is excellent improvement
4 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
safety and tolerability of Nd-YAG laser and TCA 20% in treatment of KP: adverse events
Time Frame: 4 months
adverse effects of treatment modalities, if any
4 months
