HLA antigens in persistent palmoplantar pustulosis and its relationship to psoriasis

Abstract

HLA typing was performed on 93 patients with persistent palmoplantar pustulosis. The incidence of either HLA B13 or BW17 was not significantly increased as compared to controls. In addition the frequency of BW35 was no different from controls. However, the present results document a significantly increased frequency (38.7%) of B8. Taken together these data are good evidence that palmoplantar pustulosis is a genetically distinct disease entity from psoriasis vulgaris, despite the increased incidence of psoriasis in the condition.
