Purpose of the Study. Beta lactams are the most common agents involved in allergic reactions to antibiotics. There appears to be less cross-reactivity between penicillin and the newer generation cephalosporins. These latter agents might be associated with specific immunologic responses that do not cross-react with penicillins or other cephalosporins. These investigators examined the scope of immunoglobulin E (IgE) responses to various cephalosporins and penicillins in children and adults with histories compatible with cephalosporin allergy.
Study Population. Six children and 24 adults who had experienced urticaria/angioedema or anaphylaxis after exposure to injectable cephalosporins were selected for study. Reactions had occurred 1 to 48 months before evaluation. All 6 children had reacted to ceftriaxone, and 5/6
