“…Only 20-30% of patients positive on a penicillin skin test remain positive after 10 years [104]. Five years after a positive skin test, 100% of amoxicillinallergic patients lost skin test reactivity compared to 40% of patients who reacted to a beta-lactam determinant [105]. Approximately one-third of those with a selective positive skin test for cephalosporins maintain skin test reactivity after 5 years follow-up [106].…”

SummaryThe Standards of Care Committee of the British Society for Allergy and Clinical Immunology (BSACI) and an expert panel have prepared this guidance for the management of immediate and non-immediate allergic reactions to penicillins and other beta-lactams. The guideline is intended for UK specialists in both adult and paediatric allergy and for other clinicians practising allergy in secondary and tertiary care. The recommendations are evidence based, but where evidence is lacking, the panel reached consensus. During the development of the guideline, all BSACI members were consulted using a Web-based process and all comments carefully considered. Included in the guideline are epidemiology of allergic reactions to beta-lactams, molecular structure, formulations available in the UK and a description of known beta-lactam antigenic determinants. Sections on the value and limitations of clinical history, skin testing and laboratory investigations for both penicillins and cephalosporins are included. Cross-reactivity between penicillins and cephalosporins is discussed in detail. Recommendations on oral provocation and desensitization procedures have been made. Guidance for beta-lactam allergy in children is given in a separate section. An algorithm to help the clinician in the diagnosis of patients with a history of penicillin allergy has also been included.Keywords allergy, anaphylaxis, beta-lactam, BSACI, carbapenem, cephalosporin, children, cross-reactivity, desensitization, drug provocation test, epidemiology, hypersensitivity, monobactam, oral challenges, paediatrics, penicillin, serum-specific IgE, skin tests, Standards of Care Committee • This guideline addresses immediate and non-immediate allergic reactions to beta-lactams.• Up to 20% of drug-related anaphylaxis deaths in • Individuals with a positive skin test to an aminopenicillin but negative skin tests to penicillin determinants are likely to be sensitized to the aminopenicillin side chain.

“…Most of the papers published on the usefulness of prick tests and IDT concern CADR due to betalactam antibiotics (1,24,29,(52)(53)(54). Prick tests and IDT have also been performed with other drugs such as diltiazem (45), heparin derivatives (33)(34)(35), insulin (45), oestradiol (1) and corticosteroids (56).…”

Guidelines for performing skin tests withdrugs in the investigation of cutaneous adverse drug reactions

et al. 2001

Skin testing with a suspected drug has been reported to be helpful in determining the cause of cutaneous adverse drug reactions (CADR). Many isolated reports of positive drug skin tests are published, but without detailed information concerning the clinical features of the CADR and the method used in performing drug skin tests, such data are not very informative. A working party of the European Society of Contact Dermatitis (ESCD) for the study of skin testing in investigating cutaneous adverse drug reactions, has proposed the herein-reported guidelines for performing skin testing in CADR in order to standardize these procedures. In each reported case, the imputability of each drug taken at the onset of the CADR and a highly detailed description and characterization of the dermatitis need to be given. Drug skin tests are performed 6 weeks to 6 months after complete healing of the CADR. Drug patch tests are performed according to the methods used in patch testing in studying contact dermatitis. The commercialized form of the drug used by the patient is tested diluted at 30% pet. (pet.) and/or water (aq.). The pure drug is tested diluted at 10% in pet. or aq. In severe CADR, drug patch tests are performed at lower concentrations. It is also of value to test on the most affected site of the initial CADR. Drug prick tests are performed on the volar forearm skin with the commercialized form of the drug, but with sequential dilutions in cases of urticaria. Intradermal tests (IDT) are performed with sterile sequential dilutions (10-4, 10-3, 10-2, 10-1) of a pure sterile or an injectable form of the suspected drug with a small volume of 0.04 ml. Drug skin tests need to be read at 20 min and also later at D2 and D4 for patch tests, at D1 for prick tests and IDT. All these tests also need to be read at 1 week. The success of skin tests varies with the drug tested, with a high % of positive results, for example, with betalactam antibiotics, pristinamycin, carbamazepine and tetrazepam on patch testing, or with betalactam antibiotics and heparins on delayed readings of IDT. The results of drug skin tests also depend on the clinical features of the CADR. The use of appropriate control patients is necessary to avoid false-positive results.

“…Alternatively, sensitivity of skin tests might decrease over time, a phenomenon particularly relevant for antibiotics (10,11). In contrast, skin tests for neuromuscular blocking agent (NMBA) will usually remain positive for a long period of time (12).…”

Anaesthesiologists administer several drugs while providing general anaesthesia. Many of these drugs can elicit adverse drug reactions that fall apart into two major types. First, reactions that are usually dose-dependent and related to the pharmacological properties of the drug and/or its metabolites. Second, reactions that are unrelated to the drug's pharmacological characteristics and that are less dose-dependent. These reactions comprise drug intolerance, idiosyncratic reactions and drug-induced immune-mediated allergic and nonimmune-mediated so-called pseudo-allergic or anaphylactoid reactions. The terms anaphylactic and anaphylactoid, however, have been used inconsistently in the literature. Therefore, the nomenclature task force set up by the European Academy of Allergy and Immunology (EAACI) has proposed that anaphylactic-type reactions should be reclassified into allergic anaphylaxis and nonallergic anaphylaxis. Allergic anaphylaxis being further subdivided in IgE-mediated and non-IgE-mediated reactions (1).The exact prevalence of anaphylaxis during anaesthesia is difficult to ascertain. The estimated overall frequency has been reported to vary between 1 in 3500 and 1 in 13 000 procedures in French series (2, 3) and between 1 in 10 000 and 1 in 20 000 in an Australian study (4). The clinical manifestation of these reactions is not infrequently an almost immediate generalized response with bronchospasm and hypotension. The degree of severity varies and does not allow differentiation between an IgE-mediated or non-IgE mediated reaction resulting from nonspecific mediator release (5). The mortality from these reactions is in the range from 3 to 6%, and an additional 2% of patients experience significant residual brain damage (4).Diagnosis of anaphylaxis during anaesthesia is not always straightforward. It can be hampered as a broad spectrum of different drugs can elicit heterogeneous allergic and nonallergic reactions with distinct and sometimes unclear pathological mechanisms. Problems are certainly compounded as multiple drugs need to be administered during general anaesthesia. In addition, nonanaesthesia related drugs or procedures (e.g. disinfection) are sometimes administered/performed in the perioperative period and can also be the cause of an allergic reaction.In addition, none of the available diagnostic tests demonstrates absolute accuracy. False-positive test Correct management of anaphylaxis during anaesthesia requires a multidisciplinary approach with prompt recognition and treatment of the acute event by the attending anaesthesiologist, and subsequent determination of the responsible agent(s) with strict avoidance of subsequent administration of all incriminated and/or cross-reacting compounds.However, correct identification of the causative compound(s) and safe alternatives is not always straightforward and, too often, not done.This review is not intended to discuss acute management of anaesthesia-related anaphylaxis but summarizes the major causes of anaphylaxis during anaesthesia and the di...
