[HLA pattern in patients with post-herpetic erythema exsudativum multiforme]

33 patients suffering from postherpetic erythema multiforme (PEM) were investigated with special reference to histocompatibility typing. In comparison with a control group (n = 54), we found strikingly high levels of HLA-DR1 and HLA-DR4 as well as a significantly elevated level of HLA-Cw3 in our patients (p less than 0.01).
