Abstract

HLA-Cw6 is strongly associated with psoriasis and has been suggested to be the PSORS1 gene that confers susceptibility to early-onset psoriasis. In this study of the clinical features of HLA-Cw*0602-positive and -negative psoriasis patients in a Han Chinese population, we typed HLA-C in a cohort of 679 patients and compared the two groups. Cw*0602-positive patients (n=345) had an earlier disease onset (p < 1 x 10(-5)), more severe disease (p < 1 x 10(-3)), higher frequency of guttate psoriasis (p < 1 x 10(-9)), more affected legs and trunk (p < 1 x 10(-5)), higher incidence of Köbner's phenomenon (p=0.005) and of trauma history (p=0.009). Cw*0602-negative patients (n= 334) had more palmoplantar pustulosis (p=0.004), nail changes (p=0.001) and scalp involvement (p=0.007). However, there was no statistically significant difference between the two groups regarding age, gender, incidence of plaque psoriasis, erythrodermic, inverse, psoriatic arthritis, and the precipitation factors stress and infection. The study showed that Cw*0602-positive patients had some obvious clinical differences from Cw*0602-negative patients in a Han Chinese population, which provides evidence for an HLA-Cw*0602-associated phenotype in psoriasis.
