Abstract
AIM: To evaluate the morphostructural aspects and nail vascularity in the nail unit of patients with psoriasis, and to evaluate whether there are differences among psoriatic patients with and without nail involvement. MATERIAL AND METHODS: Nail plates and nail bed changes, nail fold vessel resistance index (NVRI), power and color Doppler blood flow appearances were investigated in 23 patients with moderate-to-severe psoriasis, with and without nail involvement, and compared to those of 11 healthy participants. RESULTS: Ventral nail plate deposits were present only in psoriasis patients. Irregular or totally fused nail plates and increased nail plate thickness was frequently observed in psoriasis patients compared to controls. NVRI was increased in psoriatic patients' nails compared to controls (0.62 vs. 0.57, p<0.0001). In the psoriasis patient group there was significant statistical difference in NVRI in patients with nail involvement compared to those without (0.66 vs. 0.55, p<0.0001). CONCLUSIONS: High-frequency gray scale sonography provides valuable information regarding morphostructural changes in nail unit structure in patients with psoriasis. Power Doppler imaging enables blood flow assessment in psoriasis nail induced changes.
