The clinical severity score of chronic actinic dermatitis correlates with <i>in vivo</i> photoallergic reactions and the immunologic parameters related to a shift towards Th2 immunity from the Th2/Th1 balanced status in patients with chronic actinic dermatitis

Abstract

The CSS-CAD correlates with total IgE level, PB eosinophil count and a shift towards Th2 immunity from Th2/Th1. So we suggest the Th1/Th2 dysbalance may be affected by the CSS-CAD.
