Efficacy of Combined Fractional Carbon Dioxide Laser and Topical Tazarotene in the Treatment of Psoriatic Nail Disease

August 25, 2017 updated by: Ayat Mahmoud, Assiut University

Efficacy of Combined Fractional Carbon Dioxide Laser and Topical Tazarotene in the Treatment of Psoriatic: Nail Disease a Single-blind, Intrapatient Left-to-right Controlled Study.

Nail psoriasis has a high incidence amongst patients with psoriasis.It is estimated to affect 80% of psoriatic patients at some time during their lives and has a significant adverse influence on their quality of life.

Treatment of nail psoriasis is disappointing, as it is refractory to treatment, with conventional therapies often having little effect.

Study Overview

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

The characteristic lesions affecting the nail present as 'oil drop' discoloration, splinter haemorrhages, subungual hyperkeratosis, and onycholysis in the nail bed or pitting, leuconychia, erythema of the lunula and crumbling in the nail matrix.Diagnosis is customarily made by patient history and physical examination, though it may be necessary to rule out onychomycosis as a differential diagnosis.

The nail psoriasis severity index has recently been reported as a possible reproducible, objective, and simple tool for clinical assessment of psoriatic nail disease.

The modified target nail psoriasis severity index has been proposed for target nail assessment which would give a degree of gradation for each parameter of 0 to 3 (0 = none, 1 = mild, 2 = moderate, and 3 = severe) in each quadrant.The topical therapies include topical and intralesional corticosteroids , topical vitamin D3 analogues (calcipotriol) , topical tacrolimus and tazarotene[8]. The efficacy of these topical therapies in nail disease is limited mainly by the impenetrability or low penetrability of the nail and nail matrix. In patients with nail psoriasis that is resistant to topical therapies, conventional systemic therapies (e.g., phototherapy, retinoids, cyclosporine, methotrexate) have been shown to be partially effective. More recently, biological therapies (e.g., infliximab, adalimumab, alefacept, etanercept) have proven efficacy in psoriasis and psoriatic arthritis, and some are effective in treating nail disease in patients with psoriasis .

Previous study proved successful treatment of onychodystrophy using fractional carbon dioxide laser with topical steroid. Fractional Carbon dioxide laser might be an effective therapy for nail psoriasis due to its ablative ability which produce microscopic holes that perhaps improve topical drug delivery. Moreover it was hypothesized that tissue ablation and remodelling process stimulate rejuvenation of the abnormal nail bed.The investigators hypothesized that the combination of Fractional carbon dioxide laser and topical tazarotene treatment will have a higher therapeutic effect on nail psoriasis through multiple mechanism.

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.
