简要总结
Penicillin is one of the earliest discovered antibiotics and a drug of choice for several infections. Up to 10 to 20% of all patients in clinical trial are labeled as penicillin allergic. Most of these patients do not have a true allergy but few have had it verified. Approximately 80% of patients with IgE-mediated penicillin allergy lose their sensitivity after 10 years. Several studies have been conducted denying the risk of sensitization following negative testing of penicillin allergy. Investigators have not had the same experience and have therefore decided to conduct a retrospective study review of 83 adult outpatients with a distant penicillin allergy label and evaluate outcomes of skin retesting six weeks following Drug Provocation Test and challenge.

结局指标
主要结局
efficacy of repeated skin testing
时间窗: week 4
verified efficacy of repeated skin testing 4 weeks or more after drug provocation test and challenge in distant penicillin allergic patients. The reagents used for skin testing were as follow: Penicillin G, Clamoxyl, Augmentin,Tienam, Histamine and Normal saline (negative control). A skin test producing a papule with a diameter greater then 3 mm is considered as positive.
次要结局
