摘 要:Background: Amino-penicillins are a major cause of delayedtype reactions to penicillins. Objectives The aim of this study was to establish a diagnostic app roach for the characterization of the individual penicillin-specific polyclona l lymphocyte reactivity in order to detect side chain-specific sensitization t o amino-penicillins. Patients can then be advised to undergo a tolerance test with safe penicillins instead of provocation with culprit penicillins for confir mation of penicillin allergy. Methods: We investigated penicillin-specific pol yclonal lymphocyte reactivity in nine patients with delayed-type reactions to amino-penicillins by a combined in vivo (patch, prick and intracutaneous tests with delayed readings) and in vitro (lym-phocyte transformation test, LTT) ap proach. Results: A combination of LTT and skin tests improved the sensitivity fo r the characterization of penicillin-specific polyclonal lymphocyte reactivity and allowed the detection of three different patterns of lymphocyte reactivity. Four patients showed a side chain-specific sensitization to amino-penicilli ns in vivo and in vitro and were advised to undergo tolerance tests with safe pe nicillins. Two patients agreed and were exposed to parenteral benzyl-penicilli n and oral phenoxymethyl-penicillin which they tolerated without complications . Conclusions: These data suggest that a combined in vivo and in vitro approach is helpful for the detection of side chain-specific sensitization to aminopeni cillins. Patients with such sensitization are very likely to tolerate safe penic illins, thereby expanding their therapeutic options when antibiotic treatment is required.
