Abstract

French

Background:

Treating nail psoriasis is challenging. Corticosteroid matrix injection with needle is a conventional treatment but pain is often a limitation.

Objective:

Evaluate efficacy and safety of triamcinolone acetonide needle-free injection with the Med-Jet MBX in psoriatic fingernail.

Methods:

Seventeen patients were enrolled between January 2012 and January 2013. Four treatments sessions were scheduled every 4 ± 1 weeks. Clinical efficacy was evaluated according to Nail Psoriasis Severity Index (NAPSI) score of target nail differences before and after the treatment.

Results:

Mean baseline NAPSI score was 6.5 on an 8-point scale (95% confidence interval [CI] 5.652–7.348) and mean final NAPSI score was 2.8 on an 8-point scale (95% CI 1.859–3.741), demonstrating statistically significant treatment efficacy (p=.0007). NAPSI score for target nail from baseline to end of treatment was decreased by 46.25%.

Conclusion:

Treatment with triamcinolone acetonide delivered by Med-Jet MBX is a safe, minimally painful and effective treatment for nail psoriasis.
