Asthma care has increasingly focused on personalised management for severe asthma, and recognition of the role and importance of comorbid conditions has increased. Severe asthma can be crippling; associated comorbid conditions often play a key role in the significant disease morbidity and frequently contribute to a severe and difficult-to-treat asthma phenotype. Comorbid conditions can be broadly grouped as being either airway-related or airway-unrelated. Airway-related comorbid conditions with the greatest impact are allergic rhinitis, chronic rhinosinusitis, vocal cord dysfunction, lung fungal sensitisation and underlying structural lung disease. The most important airway-unrelated comorbid conditions are obesity, obstructive sleep apnoea, gastro-oesophageal reflux disease and anxiety and depression. A diagnostic and management algorithm for comorbid conditions in severe asthma is outlined. It concentrates initially on the group with common comorbid conditions that can be managed in primary care. If asthma remains troublesome, emphasis can shift to identifying uncommon and more complex factors. The algorithm allows for personalised diagnostic and management pathways to be implemented. Personalised diagnosis and management of comorbid conditions are essential to achieving effective and improved outcomes for patients with severe asthma.
