title: Delayed cutaneous hypersensitivity reactions in hemophiliac subjects treated with factor concentrate.
abstract: Cutaneous delayed-type hypersensitivity was measured using the Multitest CMI in a group of 97 patients with hemophilia who were enrolled in the New England Area Comprehensive Clinic. The Multitest CMI is a multipuncture system that dispenses seven test antigens including tetanus, diphtheria, Streptococcus, Proteus, tuberculin, Candida, and Trichophyton, and a glycerine-saline control solution. A reaction was considered positive if there was induration of at least 2 mm. If the results of one or more skin tests were positive, the patient was considered to have a positive reaction. Of the 83 patients with severe or moderate hemophilia A, 51 percent had negative reactions. No study control subject and only one patient with hemophilia B had a negative reaction. The 42 patients with hemophilia A who showed no reaction used a significantly greater amount of factor VIII concentrate than did those with hemophilia A who responded positively (1,960 units/kg per year versus 1,360 units/kg per year; p less than 0.025) and included a higher percent of patients who had seropositive results for human T lymphotropic virus type III (HTLV-III) antibody (89 percent versus 69 percent, p less than 0.025).
