“…In a cohort of 41 amoxicillin-allergic patients, followed up over a 4-year period with both BAT and RAST tests every 6 months, the disappearance of IgE-specific antibody was earlier with BAT than with RAST. However, the difference was only significant when amoxicillin and not benzylpenicillin was used as the hapten [174]. The clinical utility of BAT, however, remains limited by the requirement for fresh blood, specialized laboratory equipment and technician time and therefore remains largely a research tool until its role can be fully defined.…”

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.

(D) • If a cephalosporin is required in a patient with a clinical history of penicillin allergy and positive skin tests -the patient should undergo skin testing using a cephalosporin with a different side chain and, if negative, provocation testing should be undertaken to exclude allergy to the specific cephalosporin.

(B) If skin tests are positive, then penicillin avoidance or desensitization can be considered. (B)• If a cephalosporin is required by a patient with a previous reaction, skin testing to penicillins and the required cephalosporin should be carried out to establish whether sensitization is to the beta-lactam core or side chain.

“…Such high variability may be due to the different concentrations used in the studies (undiluted ICM can be associated with false positives), the time between the reaction and the study, the clinical symptoms of the patients included, symptom severity, and the type of ICM (ionic or nonionic) [81]. As occurs with IgE-mediated reactions to drugs, if the time between the reaction and the study is longer, the chance of obtaining a positive result will be lower [83,84]. The specificity of intradermal skin tests is estimated at 96.3% [80].…”

The objective of these guidelines is to ensure efficient and effective clinical practice. The panel of experts who produced this consensus document developed a research protocol based on a review of the literature. The prevalence of allergic reactions to iodinated contrast media (ICM) is estimated to be 1:170 000, that is, 0.05%-0.1% of patients undergoing radiologic studies with ICM (more than 75 million examinations per year worldwide). Hypersensitivity reactions can appear within the first hour after administration (immediate reactions) or from more than 1 hour to several days after administration (nonimmediate or delayed reactions). The risk factors for immediate reactions include poorly controlled bronchial asthma, concomitant medication (eg, angiotensin-converting enzyme inhibitors, ß-blockers, and proton-pump inhibitors), rapid administration of the ICM, mastocytosis, autoimmune diseases, and viral infections. The most common symptoms of immediate reactions are erythema and urticaria with or without angioedema, which appear in more than 70% of patients. Maculopapular rash is the most common skin feature of nonimmediate reactions (30%-90%). Skin and in vitro tests should be performed for diagnosis of both immediate and nonimmediate reactions. The ICM to be administered will therefore be chosen depending on the results of these tests, the ICM that induced the reaction (when known), the severity of the reaction, the availability of alternative ICM, and the information available on potential ICM cross-reactivity. Another type of contrast media, gadolinium derivatives, is used used for magnetic resonance imaging. Although rare, IgE-mediated reactions to gadolinium derivatives have been reported. Key words: Iodinated. Gadolinium. Contrast media. Allergy. Hypersensitivity. Anaphylaxis. Immediate reactions. Nonimmediate reactions. PrologueThe objective of these guidelines is to ensure efficient and effective clinical practice in the diagnosis and management of hypersensitivity reactions to radiologic contrast media. The guidelines were developed by a panel of allergy specialists from the Drug Allergy Committee of the Spanish Society of Allergy and Clinical Immunology (SEAIC) with extensive clinical expertise in the evaluation and management of hypersensitivity reactions and broad research experience.We performed a systematic and independent review of the literature up to November 2015 and established a consensus of expert opinion. We evaluated the applicability of the guidelines in our daily clinical practice. The guidelines were evaluated and criticized by external reviewers with expertise in the field. MethodThe panel of experts who produced this consensus document developed a research protocol outlining the background to the subject of study, the objectives of the study, and the questions and hypotheses from which search criteria were defined.The main sources used for the literature search included electronic databases and archives (MEDLINE-PubMed, Science Direct, OVID) and a database of systematic re...

Perioperative hypersensitivity reactions constitute a first-line problem for anesthesiologists and allergists, so it is advisable that hospitals have a consensus protocol for the diagnosis and management of these reactions. However, this kind of protocols is not present in many hospitals, leading to problems in treatment, the communication of incidents and subsequent etiological diagnosis. In this document we present a systematic review of the available scientific evidence and provide general guidelines for the management of acute episodes and Resumen:Las reacciones de hipersensibilidad perioperatorias constituyen un problema de primera línea para los anestesiólogos y alergólogos, por lo que es recomendable que los hospitales tengan un protocolo de consenso para el diagnóstico y el tratamiento de estas reacciones. Sin embargo, este tipo de protocolos no está presente en muchos hospitales, lo que conlleva problemas en el tratamiento, la comunicación de incidentes y el posterior diagnóstico etiológico. Este documento ha sido creado por miembros del Comité de Alergia a Medicamentos de la Sociedad Española de Alergia e Inmunología Clínica (SEAIC) en colaboración con miembros de la Sociedad Española de Anestesia (SEDAR). Se ha realizado una revisión sistemática de la evidencia científica disponible y se proporcionan pautas generales para el manejo de episodios agudos y para la derivación de pacientes con reacciones de hipersensibilidad perioperatoria a los Servicios de Alergología. Se propone un algoritmo práctico para el diagnóstico etiológico y se brindan recomendaciones para el manejo de pacientes con reacciones alérgicas perioperatorias.
