1–15% of cystic fibrosis patients and 2.5% of adults with severe asthma. [ 3 ] Allergic bronchopulmonary aspergillosis (ABPA) is a condition characterised by an exaggerated response of the immune system (a hypersensitivity response) to the fungus Aspergillus (most commonly Aspergillus fumigatus). It occurs most often in people with asthma or ...
[10] Infections: urinary tract infection, sexually transmitted diseases, lower genital tract infections (e.g. bacterial vaginosis), [8] infections within the amniotic sac membranes (chorioamnionitis) [11] Tobacco use during pregnancy [10] Illicit drug use during pregnancy [11] Having had PROM or preterm delivery in previous pregnancies [8]
The pathogenesis of ACO is poorly understood, but it is thought to involve both type 2 inflammation (usually seen in asthma) as well as type 1 inflammation (seen in COPD). The incidence and prevalence of ACO are not well known. The risk factors for ACO are also incompletely understood, but tobacco smoke is known to be a major risk factor.
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 and/or exacerbations) due to abnormalities of the airways (bronchitis ...
AERD affects an estimated 0.3–0.9% of the general population in the US, including around 7% of all asthmatics, about 14% of adults with severe asthma, and ~5-10% of patients with adult onset asthma. [2] [3] [8] AERD is uncommon among children, with around 6% of patients, predominantly female, reporting disease onset during childhood. [9]
Asthma is a long-term inflammatory disease of the airways of the lungs. [ 4 ] It is characterized by variable and recurring symptoms, reversible airflow obstruction, and easily triggered bronchospasms. [ 9 ][ 10 ] Symptoms include episodes of wheezing, coughing, chest tightness, and shortness of breath. [ 3 ]
Reactive airway disease (RAD) is an informal label that physicians apply to patients with symptoms similar to those of asthma. [ 1 ] An exact definition of the condition does not exist. [ 1 ][ 2 ] Individuals who are typically labeled as having RAD generally have a history of wheezing, coughing, dyspnea, and production of sputum that may or may ...
Avoidance of antigen exposure. Treatment. Avoidance of antigen exposure and sometimes steroids. Hypersensitivity pneumonitis (HP) or extrinsic allergic alveolitis (EAA) is a syndrome caused by the repetitive inhalation of antigens from the environment in susceptible or sensitized people. [ 1 ][ 2 ] Common antigens include molds, bacteria, bird ...
