Carboxytherapy for treatment of localized chronic plaque psoriasis: Clinical and histopathologic evaluation

Summary

Background

Multiple treatment options are introduced in treatment of chronic localized plaque psoriasis but with poor adherence and poor patients' satisfaction resulting in poor treatment outcome.

Objective

In this pilot study, we investigated the safety and efficacy of carboxytherapy in treatment of chronic localized plaque psoriasis.

Methods

Thirty adult patients with chronic localized plaque psoriasis were enrolled in this study. The patients received carboxytherapy injection once/week for 8 weeks. Patients were clinically and histpathologically evaluated 2 weeks after the last treatment. Clinical response was evaluated by investigator's global assessment, total sign score, and 5-point scale for perilesional erythema. We performed 10-point visual analog scale for patient's satisfaction, and side effects. Three months after the last session we evaluate recurrence using 10-point scale.

Results

Carboxytherapy achieved treatment success in 26.6% according to investigator's global assessment and total sign score and 70% of the patients demonstrated absence of perilesional erythema. Patients were satisfied with no reported side effects. Recurrence area was within 1% -10% of the baseline area in 83.3% of the improved patients.
