title: Reactions to a bovine collagen implant. Clinical and immunologic study in 705 patients.
abstract: A small percentage of patients treated with bovine collagen implants have adverse reactions involving both the cellular and humoral types of immune response. We report a clinical follow-up of 705 subjects treated with a new bovine collagen implant, Atelocollagen (Koken Co. Ltd., Tokyo, Japan). Sensitization to the implant was evaluated in all subjects by skin testing, and humoral response was monitored in 166 subjects by measuring the level of circulating antibodies directed against bovine collagen. Twenty-seven patients (3.8%) exhibited a positive response to a skin test, and of the remaining 656 patients, an adverse reaction to the implant developed in 2.3%. We found a strong correlation between the presence of antibodies to collagen and a positive response to skin testing (92%) or an adverse reaction (100%). In the case of a borderline clinical response to bovine collagen implantation, anticollagen serologic tests appeared to be a useful tool for the identification of clinically reactive patients.
