[Sensitization to penicillin following cutaneous side-effects of ampicillin]. / Sensibilisation à la pénicilline après accident cutané dû à l'ampicilline

Sensitization to penicillin was determined in vitro in twenty subjects, 30 days after cutaneous side-effects due to ampicillin. The study inclued the detection of anti-penicillin IgE, IgM, a lymphoblastic transformation test and a leucocyte migration test. No difference could be demonstrated between the sensitization 30 days after an ampicillin reaction and the sensitization 30 days after a penicillin reaction.
