  • Assessing the Risk of Attack in the Management of Asthma: a Review and Proposal for Revision of the Current Control-Centred Paradigm
    Prim Care Respir J 2013; 22(3): 344-352 CLINICAL REVIEW Assessing the risk of attack in the management of asthma: a review and proposal for revision of the current control-centred paradigm *John D Blakey1, Kerry Woolnough2, Jodie Fellows2,3, Samantha Walker4, Mike Thomas5, Ian D Pavord6 1 Clinical Sciences, Liverpool School of Tropical Medicine, Liverpool, UK 2 Severe and Brittle Asthma Unit, Heartlands Hospital, Birmingham, UK 3 Clinical Health Psychology, Birmingham & Solihull Mental Health Foundation Trust, Birmingham, UK 4 Asthma UK, London, UK 5 Centre for Academic Primary Care, University of Southampton, UK 6 Institute for Lung Health, Glenfield Hospital, Leicester, UK Received 26th November 2012; resubmitted 27th February 2013; revised 9th April 2013; accepted 13th April 2013; online 2nd July 2013 Abstract Asthma guidelines focus on day-to-day control of symptoms. However, asthma attacks remain common. They continue to cause mortality and considerable morbidity, and are a major financial burden to the UK National Health Service (NHS) and the wider community. Asthma attacks have chronic consequences, being associated with loss of lung function and significant psychological morbidity. In this article we argue that addressing daily symptom control is only one aspect of asthma treatment, and that there should be a more explicit focus on reducing the risk of asthma attacks. Management of future risk by general practitioners is already central to other conditions such as ischaemic heart disease and chronic renal impairment. We therefore propose a revised approach that separately considers the related domains of daily control and future risk of asthma attack. We believe this approach will have advantages over the current ‘stepwise’ approach to asthma management.

The major risk factors of asthma are allergens like pollens, dust, smoking, mites in bedding and chemical irritants [63,85]. The disease may also trigger by extreme emotion, anger, fear, cold air and physical exercise and also affects distal lung parenchyma [10,25,31,33,35,75,76]. Laryngopharyngeal reflux is one of the suspected exacerbating factors for developing asthma and studies are going on to understand the real association between these two common diseases [44]. Even endocrine disorders like obesity and diabetes influence the prevalence of asthma [55,61,68,71]. World health organization has proposed different groupings and phenotypes of the severe asthma and differentiated into two categories: treatment resistance severe asthma (TRSA) and difficult to treat severe asthma (DTTSA). TRSA includes patients using maximum levels of inhaled medications and not achieving adequate levels of control whereas DTTSA is a controllable severe asthma [21]. Asthma is a treatable disease affecting more than 300 million people worldwide but if it is poorly controlled can become life threatening [2,30,41,43,47,70,86].

  • Coronavirus - Frequently Asked Questions (Faqs)
    Boundary House Medical Centre Coronavirus - Frequently Asked Questions (FAQs) 26th March 2020 What are the symptoms of Coronavirus? Stay at home if you have coronavirus symptoms which are either: A high temperature – this means you feel hot to touch on your chest or back (you do not need to measure your temperature) A new, continuous cough – this means coughing a lot for more than an hour, or three or more coughing episodes in 24 hours (if you usually have a cough, it may be worse than usual). What do I do if I have symptoms? Do not go to a GP Surgery, Pharmacy or Hospital. In the first instance use the NHS111 Coronavirus advice service online - https://111.nhs.uk/covid-19 Only telephone 111 if you cannot get help online. If you have symptoms of coronavirus you will need to stay at home for 7 days . If you live with someone who has symptoms, you will need to stay at home for 14 days from the day the first person in the home started having symptoms. If you live with someone who is 70 or over, has a long-term condition, is pregnant or has a weakened immune system, try to find somewhere else for them to stay for 14 days. If you do have to stay at home together, try to keep away from each other as much as possible. Read the advice about staying at home by following the link - https://www.nhs.uk/conditions/coronavirus-covid-19/self-isolation-advice/ In the event that your symptoms are deteriorating quickly with severe shortness of breath or any other symptoms which normally require a 999 call you must continue to use the emergency service – it is essential you mention to the 999 team that you think you might also have coronavirus.

    Clinical Asthma Syndromes and Important Asthma Mimics Christopher S King MD and Lisa K Moores MD Introduction Clinical Phenotypes Severity-Defined Exacerbation-Prone Asthma With Chronic Airflow Obstruction Treatment-Resistant Asthma Asthma Defined by Age at Onset Trigger-Related Phenotypes Inflammatory Phenotypes Why Do Phenotypes Matter? Asthma Mimics Chronic Obstructive Pulmonary Disease Vocal Cord Dysfunction Summary Asthma is a heterogeneous disorder with multiple clinical phenotypes. Phenotypes can be grouped into clinical or physiological, trigger-defined, and inflammatory phenotypes. Treatment based on inflammatory phenotyping improves clinical measures of asthma morbidity. Further study of in- dividual asthma phenotypes will improve understanding of their immunologic and pathologic char- acteristics and improve diagnosis and therapy. Because asthma is a common disorder with non- specific presenting features, other disorders are often misdiagnosed as asthma. A high index of suspicion for alternative diagnoses must be maintained when evaluating a patient who presents with clinical features suggestive of asthma, particularly if the patient presents with atypical symptoms or fails to respond to therapy.

  • Aspergillus Fumigatus Precipitins
    Division of Laboratory Medicine Immunology Aspergillus fumigatus precipitins General information Precipitin testing: These tests detect the presence of IgG antibodies to Aspergillus fumigatus, Aspergillus precipitins - see also: Farmer's lung and Avian Precipitins Specimen transport: At room temperature Repeat frequency: On appearance of new symptoms Special precautions: None Laboratory information Normal reference range: 0-40 mg/L Volume and sample type: 7ml clotted blood Method: FEIA (Fluoroenzyme immunoassay) Turnaround time (calendar days from sample receipt to authorised result): Median – 4 Participation in EQA Scheme: UK NEQAS for FUNGAL and RELATED ANTIGENS Clinical information Indications for the test: Allergic bronchopulmonary aspergillosis - IgG antibodies are a useful aid to diagnosis in the following settings: • Bronchopulmonary aspergillosis; usually presents as deteriorating or brittle asthma. IgE antibodies should also be checked. • Aspergilloma; these may form in cavities or bronchiectatic lung. For example, this test is used to check for aspergilloma in patients with cystic fibrosis. • Hypersensitivity pneumonitis 24 hours after inhalation of spores. Factors affecting the test: Aspergillus antibodies are not a recommended test for the investigation of the majority of cases of invasive aspergillosis in immunocompromised hosts. Interpreting results: IgG antibodies are infrequent in healthy individuals. 1/2 mft.nhs.uk/laboratorymedicine 1/2 Division of Laboratory Medicine Immunology In hypersensitivity pneumonitis, IgG antibodies are usually present alone. IgG antibodies, without IgE antibodies can also be seen in some cases of sub acute invasive aspergillus. In bronchopulmonary aspergillosis and aspergilloma a mixture of IgE and IgG antibodies are usually present. Bronchopulmonary aspergillosis can be caused by species other than A. fumigatus: if there is a high index of suspicion, we can send a sample to the reference laboratory to look for antibodies to other Aspergillus species.
