Diagnosis of asthma–COPD overlap: the five commandments 1) A patient with asthma may develop non-fully reversible airflow obstruction but this is not COPD, not even ACO; it is obstructive asthma. 2) A patient with asthma who smokes may also develop non-fully reversible airflow obstruction, which differs from obstructive asthma and from “pure” COPD. This is the most frequent type of patient with ACO. 3) Some patients who smoke and develop COPD may have a genetic Th2 background (even in the absence of a previous history of asthma) and can be identified by high eosinophil counts in peripheral blood.These individuals could be included under the umbrella term of ACO. 4) A patient with COPD and a positive bronchodilator test (>200 mL and >12% FEV1 change) has reversible COPD but is not an asthmatic, or even ACO. 5) A patient with COPD and a very positive bronchodilator test (>400 mL FEV1 change) is more likely to have some features of asthma and could also be classified as ACO.
Personalised Medicine for Asthma and Chronic Obstructive Pulmonary Disease Asthma and chronic obstructive pulmonary disease (COPD) are prevalent condition sboth significant heterogeneity within each of these conditions and additionally significant overlap in many of the clinical and inflammatory features useful clinical and immunological biomarkers which inform about prognosis and response to therapy have emerged in both asthma and COPD. These biomarkers will allow both better targeting of existing treatments and the identification of those patients who will respond to novel therapies which are now becoming available Delivery of precision medicine in airways disease is now feasible and is a core component of a personalised healthcare delivery in asthma and COPD
Use of Biological Agents in Asthma: Despite advances in asthma initiatives, there continues to be a large population of patients with severe asthma whose condition remains uncontrolled despite the use of inhaled combination corticosteroids and long-acting beta-agonist treatment. For this population, which may include as many as one-third of all patients with asthma, biological therapy is often a treatment consideration in specialist clinics.
Severe allergy asthma Characterized by clinical features of allergy to specific aeroallergens and increased levels of total or specific immunoglobulin E (IgE). Therefore, allergic asthma is characterized by high IgE levels and positive skin prick tests or specific IgE in serum and clinical symptoms compatible with exposure to the allergen. House dust mite and cat sensitization are the most prominent allergens associated with asthma severity. severe sinus disease (odds ratio [OR] 3.7), gastroesophageal reflux (OR, 4.9), recurrent respiratory infections (OR, 6.9), psychological dysfunctioning (OR, 10.8) and obstructive sleep apnea (OR, 3.4). Moreover, control is difficult to achieve in obese patients and in patients who do not adhere to medication or healthy lifestyle recommendations.
An Update on Lymphocyte Subtypes in Asthma and Airway Disease Inflammation is a hallmark of many airway diseases. Improved understanding of the cellular and molecular mechanisms of airway disease will facilitate the transition in our understanding from phenotypes to endotypes, thereby improving our ability to target treatments based on pathophysiologic characteristics. For example, allergic asthma has long been considered to be driven by an allergen-specific T helper 2 response. However, clinical and mechanistic studies have begun to shed light on the role of other cell subsets in the pathogenesis and regulation of lung inflammation.
