There are no widely accepted diagnostic criteria for ACO. However, the diagnosis requires clinical features of both asthma and COPD. [3] One diagnostic criteria, based on expert consensus, first described in 2016, requires the presence of three major and at least one minor criteria for the diagnosis of ACO.
Also, diagnostic criteria may include an increase in frequency and severity of coughing, [5] as well as increased shortness of breath. [ 7 ] A chest X-ray is usually performed on people with fever and, especially, hemoptysis (blood in the sputum), to rule out pneumonia and get information on the severity of the exacerbation.
An overlap syndrome is a medical condition which shares features of at least two more widely recognised disorders. Examples of overlap syndromes can be found in many medical specialties such as overlapping connective tissue disorders in rheumatology , and overlapping genetic disorders in cardiology .
The diagnosis of COPD is established through spirometry although other pulmonary function tests can be helpful. A chest X-ray is often ordered to look for hyperinflation and rule out other lung conditions but the lung damage of COPD is not always visible on a chest x-ray. Emphysema, for example, can only be seen on CT scan.
Chronic obstructive pulmonary disease (COPD) is a type of progressive lung disease characterized by chronic respiratory symptoms and airflow limitation. [8] GOLD 2024 defined COPD as a heterogeneous lung condition characterized by chronic respiratory symptoms (dyspnea or shortness of breath, cough, sputum production or exacerbations) due to abnormalities of the airways (bronchitis ...
The ICD-10 Clinical Modification (ICD-10-CM) is a set of diagnosis codes used in the United States of America. [1] It was developed by a component of the U.S. Department of Health and Human services, [ 2 ] as an adaption of the ICD-10 with authorization from the World Health Organization .
Bronchial hyperresponsiveness is a hallmark of asthma but also occurs frequently in people with chronic obstructive pulmonary disease (COPD). [2] In the Lung Health Study, bronchial hyperresponsiveness was present in approximately two-thirds of patients with non-severe COPD, and this predicted lung function decline independently of other ...
Asthma phenotyping and endotyping has emerged as a novel approach to asthma classification inspired by precision medicine which separates the clinical presentations of asthma, or asthma phenotypes, from their underlying causes, or asthma endotypes. The best-supported endotypic distinction is the type 2-high/type 2-low distinction.
