This guidance for the management of patients with allergic and non‐allergic rhinitis has been prepared by the Standards of Care Committee (SOCC) of the British Society for Allergy and Clinical Immunology (BSACI). The guideline is based on evidence as well as on expert opinion and is for use by both adult physicians and paediatricians practicing 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 SOCC. Where evidence was lacking, consensus was reached by the experts on the committee. Included in this guideline are clinical classification of rhinitis, aetiology, diagnosis, investigations and management including subcutaneous and sublingual immunotherapy. There are also special sections for children, co‐morbid associations and pregnancy. Finally, we have made recommendations for potential areas of future research.

Allergic rhinitis (AR) affects more than 20% of the population in the United Kingdom and western Europe and represents a major cause of morbidity that includes interference with usual daily activities and impairment of sleep quality. This guidance prepared by the Standards of Care Committee (SOCC) of the British Society for Allergy and Clinical Immunology (BSACI) is for the management of AR in patients that have failed to achieve adequate relief of symptoms despite treatment with intranasal corticosteroids and/or antihistamines. The guideline is based on evidence and is for use by both adult physicians and paediatricians practising allergy. 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 SOCC. Where evidence was lacking, consensus was reached by the experts on the committee. Included in this guideline are indications and contraindications for immunotherapy, criteria for patient selection, the evidence for short‐ and long‐term efficacy of subcutaneous and sublingual immunotherapy, and discussion on safety and the different modes of immunotherapy including, pre‐seasonal and co‐seasonal treatments. There are sections on children, allergen standardization, vaccines used in the United Kingdom, oral allergy syndrome, cost effectiveness of immunotherapy and practical considerations of undertaking immunotherapy including recommendations on who should undertake immunotherapy and dosing schedules. Finally, there is discussion on potential biomarkers of response to immunotherapy, the use of component‐resolved diagnostics, novel approaches, alternative routes and potential areas for future research.

BackgroundApproximately 210 million people are estimated to have chronic obstructive pulmonary disease [COPD] worldwide. The burden of disease is known to be high, though less is known about those of a younger age. The aim of this study was to investigate the wider personal, economic and societal burden of COPD on a cross country working-age cohort.MethodsA cross-country [Brazil, China, Germany, Turkey, US, UK] cross-sectional survey methodology was utilised to answer the research questions. 2426 participants aged 45-67 recruited via a number of recruitment methods specific to each country completed the full survey. Inclusion criteria were a recalled physician diagnosis of COPD, a smoking history of > 10 pack years and the use of COPD medications in the previous 3 months prior to questioning. The survey included items from the validated Work Productivity and Activity Impairment [WPAI] scale and the EuroQoL 5 Dimension [EQ-5D] scale. Disease severity was measured using the 5-point MRC [Medical Research Council] dyspnoea scale as a surrogate measure.Results64% had either moderate [n = 1012] or severe [n = 521] COPD, although this varied by country. 75% of the cohort reported at least one comorbid condition. Quality of life declined with severity of illness [mild, mean EQ-5D score = 0.84; moderate 0.58; severe 0.41]. The annual cost of healthcare utilisation [excluding treatment costs and diagnostic tests] per individual was estimated to be

141 m [£89.6 m]. As the mean age of retirees was 58.3 and average time since retirement was 4 years, this suggests the average age of retirement is around 54. This would mean a high societal and economic impact in all study countries, particularly where typical state retirement ages are higher, for example in Brazil, Germany and the UK [65] and the US [65,66,67], compared to Turkey [58 for women, 60 for men] and China [60].ConclusionsAlthough generalisation across a broader COPD population is limited due to the varied participant recruitment methods, these data nevertheless suggest that COPD has significant personal, economic and societal burden on working age people. Further efforts to improve COPD diagnosis and management are required.

The standardized and mini versions of the PAQLQ are valid, reliable, and responsive measurement tools

Rhinitis is a common problem in primary care which is often managed sub-optimally. It causes considerable morbidity and has been shown to have a detrimental impact on peoples ability to concentrate at school and at work. Rhinitis and asthma often present together, and symptomatic rhinitis can be associated with poor asthma control and increased risk of exacerbations. There is therefore a clear need to recognise and treat rhinitis according to guideline recommendations. This article is a primary care summary of the British Society for Allergy & Clinical Immunology (BSACI) Standards of Care Committee guideline on the management of rhinitis, written by a multi-disciplinary group of clinicians. It takes into account the time restrictions on assessment and the tests and equipment available in primary care, as well as the need for practical, clear and intuitive strategies for investigation and management. It recommends a stepwise approach to treatment, and highlights the relevance of less frequently prescribed treatments, including nasal douching leukotriene receptor antagonists and anticholinergics. Red flag symptoms are identified, together with indicators for referral. As with many other long term conditions, good communication between primary and secondary care in terms of timely and appropriate referral is a key factor for success.
