Filter by:This study is to assess the pattern of isolated fungi from the respiratory air way (bronchial tree) from bronchoalvealar lavage (BAL) in asthmatic patients with uncontrolled or difficult to treat asthma
The purpose of this study is to define the standard use of TCM treatment regimen as the TCM cohort group and the non-TCM cohort group of those who use conventional Western medicine treatment without the standard TCM treatment regimen through a multi-center, large-sample prospective cohort study design. To evaluate the clinical efficacy and safety of TCM treatment regimens in the treatment of bronchial asthma, and to provide high-quality evidence for the promotion and application of TCM syndrome differentiation treatment in bronchial asthma.
Our goals is to assess : 1¬_ the role of spirometer in case of asthma exacerbation 2_hematological parameters (N/L ratio & platelet indices &CRP )in asthma exacerbation for diagnosing and classifying asthma severity and its exacerbation
asthma adherence is mandatory for disease control
Non-adherence to controller therapy is one of the main reasons of poor asthma control. Adherence to medication in different studies range between 30 and 70% . Several factors related to the disease, to the patient, treatment or physician- patient relationship
The purpose of this study is to demonstrate the pharmacodynamic bioequivalence of the test product to the reference product, using bronchoprovocation (methacholine challenge testing) in adult patients with stable mild asthma.
The goal of this observational study is to learn about the frequency needed for stepping-up treatment in patients with mild and moderate bronchial asthma. The main questions this study aims to answer are: - What is the frequency and duration in which patients of asthma need to step up their treatment? - Can the criteria described in this study be applied and validated to test need for step up of asthma treatment? Participants will follow the treatment they are already receiving according to established guidelines and will be asked for regular visits for examination and spirometry. They will record symptoms score, each time they use the prescribed rescu inhaler, and morning and evening peak expiratory flow.
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.
Asthma is a heterogeneous disease, usually characterized by chronic airway inflammation. It is defined by the history of respiratory symptoms such as wheeze, shortness of breath, chest tightness and cough that vary over time and in intensity, together with variable expiatory airflow limitation. This definition was reached by consensus, based on consideration of the characteristics that are typical of asthma and that distinguish it from other respiratory conditions . Asthma is a problem worldwide, with an estimated 300 million affected individuals .It appears that the global prevalence of asthma ranges from 1% to 18% of the population in different countries .
