Exacerbations and Management of Asthma in Viral Lower Respiratory Tract Infections: The Significance of Immunoglobulin E. [PDF]
ABSTRACT Background Viral‐respiratory infections are the most prevalent illness among humans. A viral infection affecting lower respiratory tract infections (LRTI) is a critical health concern worldwide. The COVID‐19 pandemic has significantly impacted respiratory health, particularly in individuals with asthma.

Asthma in Patients With Confirmed Pulmonary Sarcoidosis. [PDF]
Pulmonary sarcoidosis and asthma can present identical symptoms, making clinical evaluation difficult if the two diseases overlap. Diagnostic challenges often lead to either overdiagnosis of asthma in patients with confirmed sarcoidosis or withholding appropriate asthma treatment.

Prevalence and triggers of self-reported nasal hyperreactivity in adults with asthma
Background: Nasal hyperreactivity (NHR) is a common feature of various rhinitis subtypes and represents a novel phenotype of rhinitis. It is being reported in two-thirds of adult rhinitis patients irrespective of the atopic status. Data on the prevalence

The relation between nonspecific hyperreactivity of the airways and atopic constitution in asthmatics [PDF]
Background/Aim. Hyperreactivity of the airways caused by inflammation in asthmatics is the most important pathophysiological change. It represents a suitable ground that in the presence of risk factors and the drivers of asthma, asthmatic attack occurs ...

The Lung Function Impairment in Non-Atopic Patients With Chronic Rhinosinusitis and Its Correlation Analysis [PDF]
Objectives Chronic rhinosinusitis (CRS) is common disease in otorhinolaryngology and will lead to lower airway abnormality. However, the only lung function in CRS patients and associated factors have not been much studied.

IL-13R alpha 2 reverses the effects of IL-13 and IL-4 on bronchial reactivity and acetylcholine-induced Ca2+ signaling [PDF]
Background: The interleukins IL-4 and IL-13 play a key role in the pathophysiology of asthma. The interleukin receptor IL-13R alpha 2 is believed to act as a decoy receptor, but until now, the functional significance of IL-13R alpha 2 remains vague ...

Epithelial barrier dysfunction in bronchial asthma
The pathogenesis of bronchial asthma is based on chronic inflammation as a response to etiological factors. It causes bron-chial hyperreactivity, remodeling of the respiratory tract and hypersecretion of mucus.

Macrophage TNF-α mediates parathion-induced airway hyperreactivity in guinea pigs. [PDF]
Organophosphorus pesticides (OPs) are implicated in human asthma. We previously demonstrated that, at concentrations that do not inhibit acetylcholinesterase activity, the OP parathion causes airway hyperreactivity in guinea pigs as a result of ...
