2020s Digital adherence and smart inhalers Smart inhalers, connected peak-flow devices, and remote monitoring expand real-world asthma management by tracking adherence, technique, and rescue use patterns, supporting earlier intervention and individualized care. Global
2025 Medical textbook chapter A medical reference work discusses modern approaches to asthma classification, including severity, symptom control, phenotypes, and endotypes.[112] Global
2025 Clinical guideline The Global Initiative for Asthma publishes an updated Global Strategy for Asthma Management and Prevention guideline.[109] Global
2025 Medical textbook chapter A medical reference chapter explains asthma phenotypes and endotypes, defining phenotypes as observable disease presentations and endotypes as underlying biological mechanisms.[113] Global
2025 Scientific publication A review article in The Lancet Respiratory Medicine examines genetic and environmental risk factors for asthma and discusses prevention strategies.[114] Global
2025 Scientific publication A review discusses asthma epidemiology, risk factors, and opportunities for prevention and treatment, including the role of tobacco smoke, respiratory infections, and environmental exposures.[115] Global
2025 Epidemiological finding Research identifies prenatal and early-life risk factors associated with asthma development, including maternal obesity, smoking during pregnancy, and caesarean section.[114] Global
2025 Epigenetic research finding Studies link prenatal exposure to cigarette smoke and nicotine with epigenetic changes that increase asthma risk in children and even grandchildren.[115] Global
2025 Epidemiological finding Research identifies chronic exposure to outdoor and indoor air pollution—including traffic emissions, biomass fuels, pesticides, and building materials—as important risk factors for asthma development.[115][102] Global
2025 Epidemiological observation Studies find asthma prevalence to be higher in urban environments than in rural settings, potentially due to air pollution, social inequality, industrialization, and reduced green space.[114] Global
2025 Clinical research finding Occupational exposures to more than 400 substances, including allergens and irritants known as asthmagens, are linked to the development of occupational asthma.[115] Global
2025 Medical classification framework Contemporary asthma research commonly divides asthma into two major endotypes: type-2-high (T2-high) and type-2-low (non-T2), distinguished by inflammatory mechanisms and immune responses.[113][108] Global
2025 Clinical research framework The type-2-high asthma endotype is characterized by type-2 immune responses and biomarkers such as increased eosinophils and elevated fractional exhaled nitric oxide (FeNO).[113] Global
2025 Clinical research framework Type-2-low asthma is defined by the absence of typical type-2 inflammatory markers and remains less well understood in terms of underlying mechanisms.[113] Global
2025 Disease subtype characterization Clinical literature identifies phenotypes associated with type-2-high asthma, including early-onset allergic asthma, late-onset eosinophilic asthma, and aspirin-exacerbated respiratory disease.[113] Global
2025 Disease subtype characterization Type-2-low asthma phenotypes include obesity-associated asthma, neutrophilic asthma, cigarette-smoke-associated asthma, and paucigranulocytic asthma.[113] Global
2025 Occupational health classification Occupational asthma is subdivided into irritant-induced asthma and sensitizer-induced occupational asthma, reflecting different pathogenic mechanisms and inflammatory profiles.[108][113] Global
2025 Clinical concept Asthma-COPD overlap (ACO) is recognized as a clinical condition combining features of asthma and chronic obstructive pulmonary disease, though a consistent definition remains lacking.[108] Global
2025 Clinical guideline concept Asthma exacerbations (asthma attacks) are defined as episodes of worsening symptoms and reduced lung function measured by peak expiratory flow (PEF) or forced expiratory volume in one second (FEV1).[109] Global
