Filter by:This is a randomized, double-blind, comparative, parallel-group study of the efficacy and safety of Genolar® and Xolair® in the treatment of persistent atopic bronchial asthma of moderate and severe course, whose symptoms are insufficiently controlled by the 4-step treatment GINA (2017)
Clinical exploring study of Weiyang Yuping Decoction in preventing acute attacks of mild to moderate intermittent asthma Based on the theory of "Preventing disease from exacerbating" in Chinese medicine.
Asthma, a disease characterized by chronic airway inflammation and hyper -responsiveness, is a common disease that affects all age groups. Asthma may be manifested as irreversible airflow obstruction in some patients. Although the pathogenesis of asthma is not well understood, increased oxidative stress due to an imbalance of oxidants and antioxidants has been found to be associated with asthma. In asthma, inflammation-related oxidative stress is driven by exposure to a variety of triggers, including allergens and viruses, which activate components of both the innate and acquired immune responses. Protection by escaping from triggering factors or standardization of asthma medication is difficult and usually is not enough for effective treatment. On the other hand, correction of antioxidative systems may be more efficacious in the control of asthmatic inflammation and asthma symptoms. Little is known about the role of asymmetric dimethylarginine in the pathogenesis of asthmatic airway inflammation. The lung is a major source of asymmetric dimethylarginine that can promote oxidative stress by a reduction in nitric oxide synthesis which would result in higher levels of peroxynitrite, that causes oxidative cell damage, and exacerbate airway inflammation. asymmetric dimethylarginine can modify lung function, increase airway hyper-reactivity even in non-inflamed airways, and promote lung collagen production and deposition. Increased asymmetric dimethylarginine in serum has been found to be associated with the severity of symptoms of asthma in obese adults. Malondialdehyde is an oxidant marker of pulmonary oxidative stress, and lipid peroxidation. Paraoxonase, an antioxidant enzyme may play a protective role in asthma. It hydrolyzes lipid peroxides and prevents low-density lipoprotein oxidation.
Exhaled breath condensate (EBC) represents a rich source for countless biomarkers that can provide valuable information about respiratory as well as systemic diseases. Finding non-invasive methods for early detection of lung injury, inflammation and infectious complications in chronic diseases like (CF) Cystic fibrosis or (AB) Bronchial asthma would be highly beneficial. Investigators propose to establish EBC "breathprints" revealing molecular signatures of pulmonary inflammation and specific respiratory bacterial infections of CF patients and AB. Investigators hypothesize that the analysis of EBC can reveal biomarkers specific for severity of the inflammation, and infection caused by opportunistic pathogens such as P. aeruginosa (PA). With these breath-prints, investigators also propose to establish correlations between respiratory microbiota using traditional methods and CF lung disease severity. Together, the studies will advance the development and validation of EBC as a novel tool for the proper diagnosis of AB and monitoring of CF disease activity, treatment efficacy and PA or another opportunistic infections.
This study aims to determine the TCM syndrome pattern and the distribution of inflammation phenotype in different stages of bronchial asthma; to explore the correlation between TCM syndrome and inflammation phenotype. Secondly screening biomarkers that can be recognized by TCM syndromes and inflammatory phenotypes of bronchial asthma, and provide a basis for individualized diagnosis and treatment of diseases.
To compare the therapeutic equivalence of Beclomethasone Dipropionate MDI (Inhalation Aerosol) 0.04 mg/ INH with the marketed QVAR® 40 mcg (Beclomethasone dipropionate hydrofluoroalkane (HFA)) and to demonstrate superiority of both active treatments over placebo.
This is an exploratory, randomized, subject- and investigator-blinded, placebo-controlled mode-of-action study to demonstrate the anti-inflammatory effects of fevipiprant compared to placebo after 12 weeks of treatment in 48 moderate to severe asthma patients with sputum and blood eosinophilia.
Study is conducted to assess the prevalence and structure of comorbidity among patients undergoing abdominal surgery and produce the stratification of the risk of postoperative complications by identifying independent predictors for its development.
Current guideline-based criteria defining bronchial asthma do not always meet the challenges set by the complex pathophysiology of the disease. The investigators therefore aimed to evaluate novel or not widely used functional diagnostic approaches for the detection and therapeutic monitoring of patients with asthma.
Asthma is a problem that affects many children and affects their physical health in addition to having a social and financial burden on individuals, families and healthcare systems. In our pediatric emergency department, nebulizers are still used for the management of asthma and, with the poor resources of families, they have no option of treatment at home. In this study, the investigators will compare the effectiveness of treatment through nebulizer versus metered dose inhaler and spacer in children with an acute asthmatic attack seeking medical care at the Pediatric Emergency Department of Suez Canal University Hospital.
