title: [HLA and keloids: antigenic frequency and therapeutic response].
abstract: Twenty keloid subjects were typed for class 1 (HLA-A, B and C) and class 2 (HLA-DR and DQ) histocompatibility antigens. Their frequencies were compared to those found in control populations. Of all the antigens belonging to class 1, B 21 was more prevalent in patients. The findings regarding class 2 antigens were noteworthy: in keloid patients there was a significant prevalence of DR 5 (RR = 3.54 and 7.93 respectively for the two control groups) and DQw 3 (RR = 16.8). The patients typed for HLA-antigens were treated with corticosteroid infiltrations. The responses to the treatments were no related to the histocompatibility antigens.
