This guidance for the management of patients with chronic urticaria and angioedema has been prepared by the Standards of Care Committee of the British Society for Allergy and Clinical Immunology (BSACI). The guideline is based on evidence as well as on expert opinion and is aimed at both adult physicians and paediatricians practising in allergy. The recommendations are evidence graded. During the development of these guidelines, all BSACI members were included in the consultation process using a Web-based system. Their comments and suggestions were carefully considered by the Standards of Care Committee. Where evidence was lacking, a consensus was reached by the experts on the committee. Included in this management guideline are clinical classification, aetiology, diagnosis, investigations, treatment guidance with special sections on children with urticaria and the use of antihistamines in women who are pregnant or breastfeeding. Finally, we have made recommendations for potential areas of future research., (© 2015 John Wiley & Sons Ltd.)

The 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., (© 2015 John Wiley & Sons Ltd.)

This guideline advises on the management of patients with egg allergy. Most commonly, egg allergy presents in infancy, with a prevalence of approximately 2% in children and 0.1% in adults. A clear clinical history and the detection of egg white-specific IgE (by skin prick test or serum assay) will confirm the diagnosis in most cases. Egg avoidance advice is the cornerstone of management. Egg allergy often resolves and re-introduction can be achieved at home if reactions have been mild and there is no asthma. Patients with a history of severe reactions or asthma should have reintroduction guided by a specialist. All children with egg allergy should receive measles, mumps and rubella (MMR) vaccination. Influenza and yellow fever vaccines should only be considered in egg-allergic patients under the guidance of an allergy specialist. This guideline was prepared by the Standards of Care Committee (SOCC) of the British Society for Allergy and Clinical Immunology (BSACI) and is intended for allergists and others with a special interest in allergy. The recommendations are evidence-based but where evidence was lacking consensus was reached by the panel of specialists on the committee. The document encompasses epidemiology, risk factors, diagnosis, treatment, prognosis and co-morbid associations.

These guidelines have been prepared by the Standards of Care Committee (SOCC) of the British Society for Allergy and Clinical Immunology (BSACI) and are intended for allergists and others with a special interest in allergy. As routine or validated tests are not available for the majority of drugs, considerable experience is required for the investigation of allergic drug reactions and to undertake specific drug challenge. A missed or incorrect diagnosis of drug allergy can have serious consequences. Therefore, investigation and management of drug allergy is best carried out in specialist centres with large patient numbers and adequate competence and resources to manage complex cases. The recommendations are evidence-based but where evidence was lacking consensus was reached by the panel of specialists on the committee. The document encompasses epidemiology, risk factors, clinical patterns of drug allergy, diagnosis and treatment procedures. In order to achieve a correct diagnosis we have placed particular emphasis on obtaining an accurate clinical history and on the physical examination, as these are critical to the choice of skin tests and subsequent drug provocation. After the diagnosis of drug allergy has been established, communication of results and patient education are vital components of overall patient management.

This guidance for the management of patients with rhinosinusitis and nasal polyposis has been prepared by the Standards of Care Committee (SOCC) of the British Society for Allergy and Clinical Immunology (BSACI). The recommendations are based on evidence and expert opinion and are evidence graded. These guidelines are for the benefit of both adult physicians and paediatricians treating allergic conditions. Rhinosinusitis implies inflammation of the nose and sinuses which may or may not have an infective component and includes nasal polyposis. Acute rhinosinusitis lasts up to 12 weeks and resolves completely. Chronic rhinosinusitis persists over 12 weeks and may involve acute exacerbations. Rhinosinusitis is common, affecting around 15% of the population and causes significant reduction in quality of life. The diagnosis is based largely on symptoms with confirmation by nasendoscopy. Computerized tomography scans and magnetic resonance imaging are abnormal in approximately one third of the population so are not recommended for routine diagnosis but should be reserved for those with acute complications, diagnostic uncertainty or failed medical therapy. Underlying conditions such as immune deficiency, Wegener's granulomatosis, Churg-Strauss syndrome, aspirin hypersensitivity and allergic fungal sinusitis may present as rhinosinusitis. There are few good quality trials in this area but the available evidence suggests that treatment is primarily medical, involving douching, corticosteroids, antibiotics, anti-leukotrienes, and anti-histamines. Endoscopic sinus surgery should be considered for complications, anatomical variations causing local obstruction, allergic fungal disease or patients who remain very symptomatic despite medical treatment. Further well conducted trials in clearly defined patient groups are needed to improve management.
