Intra-individual Right-Left Comparative Study of Combined Therapy of Intramatricial Triamcinolone and Platelet-Rich Plasma vs. Intramatricial Triamcinolone Only in Lichen Planus-Associated Nail Dystrophy.

BACKGROUND:While intramatricial triamcinolone is the most commonly used treatment option for onychodystrophy due to lichen planus, the role of platelet-rich plasma (PRP) in the treatment of onychodystrophy is not established. So we combined the two treatment modalities to assess the synergistic action on nail dystrophy. AIMS AND OBJECTIVES:The aim of this article is to compare the effect of combination of intramatricial triamcinolone and PRP vs. intramatricial triamcinolone alone in the treatment of onychodystrophy. MATERIALS AND METHODS:This study was done in 26 and 25 pairs of symmetrical dystrophic nails in hands and feet, respectively. The patients received intramatricial injection of triamcinolone and PRP on one side of finger and toe nails and triamcinolone on the contralateral side. RESULTS:Statistically significant improvements in grades of dystrophy according to the Nail Dystrophy Grading System (NDGS) in the finger and toe nails treated with combined therapy were obtained (P < 0.001 and = 0.002, respectively). According to the physician global assessment, response to combination therapy was statistically significant between the two comparison groups of finger and toe nails (P = 0.001 and = 0.004, respectively). Similarly, according to the patient satisfaction score, statistically significant difference was found between the comparison groups of combination therapy and single therapy (P < 0.001). CONCLUSION:Addition of PRP significantly improved the nail quality. Intramatricial PRP is a safe and effective therapeutic modality in refractory nail dystrophies.
