Combined Effect of Acitretin and Narrow Band Ultraviolet B on Vitiligo Repigmentation

July 17, 2021 updated by: Shahira Ramadan, Cairo University

Assessment of the Combined Effect of Acitretin and Narrow Band Ultraviolet B (Nb-UVB) on the Clinical Repigmentation and on the Expression of E-cadherins in Vitiligo Lesions in Comparison to Narrow Band UVB Alone. A Pilot Study

Since abnormal keratinocyte (KC) proliferation and differentiation as well as defective E cadherin expression were reported in vitiligo lesions, the investigators set to study the potential efficacy of combining Retinoids, which are known to improve KC proliferation and differentiation and increase the expression of adhesion molecules, with narrowband UVB in the treatment of vitiligo.

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

• Twenty patients with generalized vitiligo will be included in this study.

All patients will be subjected to:

  • Clinical evaluation:
  • An informed written consent.
  • History taking include age, previous treatment, disease activity
  • Clinical examination including Vitiligo Area Scoring Index (VASI) and Vitiligo Disease Activity Score (VIDA)
  • Photography (before starting the treatment and every 2 weeks till the end of the study)

Laboratory evaluation:

  • 2 mm punch skin biopsies will be taken from vitiligo patients, 1 from lesional and the other from perilesional skin before treatment.
  • The patients will be randomly assigned to two groups:

Group A: patients will receive three NB-UVB sessions per week for 48 sessions. Group B: patients will receive three NB-UVB sessions per week for 48 sessions combined with acitretin in a dose of 0.3mg/kg/day daily.

  • Controls: 20 individuals age and sex matched will be biopsied from the skin of their abdominoplasty surgery.
  • Another two 2 mm punch skin biopsies will be taken from lesional and perilesional skin at the onset of repigmentation if repigmentation starts before completion of the 48 treatment session or after completion of the treatment period if repigmentation does not occur.
  • .All biopsies from patients and controls will be stained Immunohistochemically by anti-E cadherin antibody.

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.

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
Determining whether addition of acitretin is beneficial for vitiligo patients or not using Vitiligo Area Scoring Index
