The combined use of HLA-B5 and the pathergy test as diagnostic markers of Behçet's disease in Turkey.

Abstract

Forty-one of 49 (84%) patients with Behçet's disease in Turkey carried HLA-B5 (positive B5). Forty of the same 49 (82%) patients had a nonspecific skin hyperreactivity to needle prick (positive pathergy). There were no patients in whom both of these tests were negative.
