CLINICAL MANIFESTATIONS OF PSORIATIC NAIL AT THE NATIONAL HOSPITAL OF DERMATOLOGY AND VENEREOLOGY (NHDV)

Abstract

Psoriasis is a common skin disease and nails are frequently involved. Although nail psoriasis occurs frequently in patients with psoriatic skin lesions, effective treatments are limited. Objective: investigating clinical manifestations of psoriatic nail at the National hospital of dermatology and venereology (NHDV). Material and method: the descriptive study was performed basing on data of all patients with psoriasis from 03/2012 to 04/2012. Results: There were 95 patients having nail lesion, accounting for 63,3% of psoriasis patients visit at NHDV, with mean nail psoriasis severity index (NAPSI) score was 43,26 ± 31,45. The proportion of psoriatic nail among difference types of psoriasis: 72,2% of plaque psoriasis, 81,2% of erythrodermic psoriasis, 34,3% of guttate psoriasis and 45,5% of pustular psoriasis. The yellow-brown and crumbling nail was the most common lesion. The mean PASI score was 18,51 8,27 and 8,25 ± 4,64 in patients with and without nail involvement, respectively. The linear relationship between NAPSI and PASI could be represented by the following equation: PASI = 0,17 NAPSI + 8,83, coefficient of determination r = 0,85.
