Aim: To analyse correlation between bronchial hypersensitivity in bronchial asthma (BA) and environmental factors; to propose methods of relevant correction.
Material And Methods: The trial included 97 BA patients (42 males, 55 females) aged 17-79 years. Bronchial sensitivity was studied by means of dose-dependent bronchial resistance curve (Rrs) plotted by the unit Masterlab (Germany) in the course of long-term inhalation of a gradually rising dose of methacholine. A regression analysis was made of the dependence of fluticasone bipropionate effectiveness on clinical symptoms of the disease.
Results: Bronchial hypersensitivity depends on initial clinical symptoms of BA, in a less degree on bronchial permeability, severity of inflammation of bronchial mucosa.
Conclusion: Local corticosteroid fluticasone propionate is a drug of choice in the treatment of mild and moderate BA.

While progress has been made in recent years, there are still no suitable and accepted , or models that can be used to accurately predict whether a chemical substance has the intrinsic property to cause immune-mediated chemical respiratory allergy, typically manifested as allergic asthma or allergic rhinitis which represents a severe health hazard. Regulatory authorities have relied primarily on clinical evidence (case reports, clinical databases, worker exposure studies) to classify substances as respiratory sensitizers, but this evidence can lack a proven immunological mechanism which is necessary to identify substances which can cause life-long sensitization and clinically relevant allergic symptoms in the respiratory tract in an exposed population (such respiratory allergens may be considered as "true" sensitizers, in analogy to the definition of skin sensitization, and in contrast to respiratory irritants). In light of this, the European Center for Ecotoxicology and Toxicology of Chemicals convened a Task Force to evaluate the types of clinical methods and data sources and the implications of relying on such data for regulatory decision making from a scientific perspective.

Allergic diseases and ulcerative colitis (UC) share pathophysiological similarities. This study aimed to investigate the unclear association between allergic diseases and mucosal healing (MH), an important factor in the prognosis of UC. We studied 289 Japanese patients with UC.

Background: NSAID-exacerbated respiratory disease (N-ERD) is a hypersensitivity to non-steroidal anti-inflammatory drugs (NSAIDs), such as aspirin or ibuprofen, accompanied by chronic rhinosinusitis (with or without nasal polyps) or asthma. The prevalence of hypersensitivity to NSAIDs is estimated to be 2%. The first line of treatment is the avoidance of NSAIDs.

Gadolinium contrast medium can serve as an alternative to iodinated contrast medium when the latter is unsuitable. In this report, we describe a case of a carotid-ophthalmic aneurysm in which angiograms were obtained using gadolinium contrast medium for flow-diverter stent placement due to the patient's history of bronchial asthma and hypersensitivity reactions to iodinated contrast medium. To enhance the visibility of gadolinium contrast medium, which typically provides lower contrast compared to iodinated contrast medium, we employed a contrast-enhancing and noise-reducing protocol on our image-guided therapy system.

Background: Some studies have suggested that the forced expiratory flow between 25 and 75% of vital capacity (FEF) can be used as an early marker of bronchial hyperresponsiveness (BHR) in asthma and allergic rhinitis (AR), but is highly variable. Here, we aimed to assess whether the FEF can be used to diagnose BHR in patients with asthma-like symptoms and AR.
