Allergic asthma is a chronic lung disease characterized by wheezing, coughing, chest tightness and shortness of breath. Clinically, the treatments against asthma focus on controlling the symptoms rather than inhibiting recurrence radically. Additionally, local and systemic side effects caused by current treatments are worthy of attention. Therefore, a novel therapeutic strategy against asthma is needed. Asatone is a pharmacologically active component from Radix et Rhizoma Asari, which has anti-inflammatory effects in lipopolysaccharide-induced lung injury. In the present study, we showed that asatone could protect mice against OVA-induced asthma, as manifested by attenuating inflammation infiltration, mucus production, and airway hyperreactivity and suppressing the elevation of IL-4, IL-5, and IL-13 in broncho-alveolar lavage fluid. Overall, results of the present study support use of asatone as a potent therapeutic strategy for clinical treatment of allergic asthma.

Diagnostic value of IgE, fractional of exhaled nitric oxide, and peripheral blood eosinophils in adult bronchial asthma and their relationship with disease severity.
Am J Transl Res
December 2024
Department of Respiratory Medicine, Hanzhong People's Hospital Hanzhong 723000, Shaanxi, China.
Objective: To investigate the diagnostic value of immunoglobulin E (IgE), fractional of exhaled nitric oxide (FeNO), and peripheral blood eosinophils (EOS) in adult bronchial asthma and to analyze their relationship with asthma severity.
Methods: A retrospective analysis was conducted on 336 patients diagnosed with bronchial asthma and admitted to Xi'an Fourth Hospital from January 2022 to January 2024, forming the asthma group. Additionally, another 127 healthy subjects were selected as the non-asthmatic control group.

Clinic for Lung Diseases Jordanovac, University Hospital Centre Zagreb, Zagreb, Croatia.
Background: Prevalence of potential drug-drug interactions (pDDIs) in adult patients with severe asthma on biological therapy and their clinical significance have not been fully addressed, thus the aim of this study was to investigate them.
Methods: In this retrospective observational study, patients who were diagnosed with severe asthma and to whom biological therapy was prescribed between September 2015 and December 2020, were enrolled. The study was conducted at the Department of Allergic and Obstructive Pulmonary Diseases, Clinic for Lung Diseases Jordanovac, Clinical Hospital Center Zagreb.
Association and mechanism of montelukast on sleep disorders: insights from NHANES 2005-2018 data analysis and a network pharmacology study.

School of Pharmacy, Hubei University of Chinese Medicine, Wuhan, China.
Background: Studies have suggested associations between montelukast and increased risks of sleep disorders, including overall sleeping problems and insomnia. However, the results of observational studies are not consistent. Understanding these associations is crucial, particularly in patients solely diagnosed with allergic rhinitis, where montelukast use remains prevalent.
