[Improvement of psoriasis by haemodialysis (author's transl)].

Haemodialysis treatment of 5 patients with therapy-resistant psoriasis showed that certain clinical forms seem to respond to such treatment. Each patient had at least one of the frequently occurring antigens of psoriatic patients in his HLA match (B 13, B17, B 27, B 37, Cw 6). Of these antigens B 37, B 13 and B 27 were found only in such patients where treatment was successful. The HLA-B 37 antigen was associated with generalised, HLA-B 13 with chronic stationary and HLA-B 27 with arthropathic manifestation of psoriasis.
