The latest Ipsos MORI Asthma UK survey, this year part funded by Merck Sharp & Dohme Limited, found that over two thirds (67 per cent) of the 1,235 respondents diagnosed with asthma also suffered from symptoms of allergic rhinitis (hayfever) including runny nose, sneezing or itchy or red eyes. In addition, 72 per cent of those said their asthma became worse when they experienced allergic rhinitis symptoms. These findings support the increasing recognition that asthma and allergic rhinitis are associated conditions.
Asthma and allergic rhinitis commonly co-exist and both cause inflammation of the airway. Previous research has reported that at least 50 per cent of asthma patients also suffer from allergic rhinitis. Research also shows that the presence of allergic rhinitis increases the risk of asthma attacks and emergency hospitalisation. However, 65 per cent of survey respondents with allergic rhinitis symptoms said that their healthcare professional (doctor, nurse or pharmacist) had never discussed its impact on asthma control.
For the majority of people surveyed (84 per cent), symptoms were most severe during the spring or summer months, when pollen levels are high and hayfever is more prominent. However, 20 per cent of respondents experience allergic rhinitis symptoms all year round, suggesting that people with asthma need to regularly monitor their symptoms.
Dr John Haughney, president of the International Primary Care Respiratory Group, and GP in Glasgow said: "This survey highlights the impact that co-morbid conditions can have on asthma and the important role that healthcare professionals can play in monitoring and treating upper airway symptoms, particularly in those patients where asthma is not adequately controlled. The results support the recommendations of the World Health Organisation 'ARIA' guideline, which says that clinicians should always look for evidence of allergic rhinitis in people with asthma, and that treating both upper and lower airways inflammation is likely to produce the better results for the patient."
