Bronchial Asthma

Asthma is a chronic inflammatory airway disease associated with variable airflow limitation and persistent respiratory symptoms. Vitamin D has been proposed as a potential biomarker related to immune regulation, asthma control, pulmonary function, and oxidative stress balance. This prospective cross-sectional observational study aims to investigate the association between serum 25-hydroxyvitamin D \[25(OH)D\] concentrations, asthma control, pulmonary function parameters, and erythrocyte oxidative stress biomarkers among Egyptian adults with bronchial asthma. A total of 200 adult asthma patients will be recruited from Abbassia Chest Hospital, Cairo, Egypt. Participants will undergo clinical assessment, Asthma Control Test (ACT), post-bronchodilator spirometry, serum vitamin D measurement, and oxidative stress biomarker assessment including malondialdehyde (MDA), superoxide dismutase (SOD), glutathione peroxidase (GPx), and reduced glutathione (GSH). Participants will be categorized according to serum 25(OH)D concentrations into vitamin D deficient, insufficient, and sufficient groups. No intervention or treatment assignment will be performed. 5\. Detailed Description

This phase IV randomized controlled trial is designed to evaluate the effects of chromium picolinate supplementation in obese adults with stable asthma. A total of 60 participants will be recruited from Ain Shams University Hospitals and randomly assigned to receive either 400 mcg of chromium picolinate daily or a matching placebo for 12 weeks, in addition to standard asthma therapy. The study aims to explore the interaction between metabolic dysfunction and asthma, as obesity-related asthma is often associated with systemic inflammation, insulin resistance, and dyslipidemia. These factors may contribute to poorer asthma control and impaired pulmonary function, and therefore represent potential targets for adjunctive therapeutic interventions such as chromium supplementation.

Based on the bioholographic theory, this study preliminarily explores the clinical efficacy of hand acupuncture in treating acute exacerbation of bronchial asthma and evaluates its immediate anti-asthmatic effect, so as to provide a new therapeutic strategy for the clinical management of bronchial asthma.

Lung health is negatively affected during wildfire season by increased smoke pollution. Wearing N95 masks protects lung health in the short-term. The purpose of our study is to assess whether wearing of N95 facemasks on days with moderate to high air pollution in people who go outside to golf on a regular basis (two or more times per week) for two months during the wildfire season projects lung health.

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.

The goal of this clinical trial is to learn if community-based exercise training can benefit patients aged 18 to 85 with diminished cardiovascular and pulmonary function. The main aim of this study is: • Establish a community or home-based fitness training program for patients with cardiopulmonary insufficiency to improve adherence, safety, and efficacy while alleviating the burden on both patients and society. Researchers will compare community-based exercise training to non-exercise training to see if community-based exercise training works to improve cardiovascular and pulmonary function. Participants will: * Engage in community or home exercise training for 40-60 minutes, five times weekly, during a duration of eight weeks. Exercise modalities are primarily determined by the patients' individual preferences and habits, such as brisk walking, running, swimming, cycling, and hiking. * Adjust the exercise intensity according to their cardiopulmonary exercise test and the person's perceived exertion level. * Utilize fitness bracelets or watches to document statistics during workouts and submit them to the experimenter weekly, covering the five days of exercise within that week. * refrain from making any dietary modifications throughout the trial.

Research is being conducted into chronic respiratory diseases, including chronic obstructive pulmonary disease (COPD), asthma, interstitial lung disease, and bronchiectasis. The investigation specifically focuses on sleep-disordered breathing (SDB) in individuals with chronic respiratory disease. SDB encompasses a range of conditions, the most common of which is obstructive sleep apnoea. In obstructive sleep apnoea, periodic pauses in breathing (apnoea) lead to reduced blood oxygen levels. To detect these events, patients typically undergo sleep studies that involve monitoring oxygen saturation, heart rate, and respiratory patterns during sleep. When chronic respiratory disease and SDB coexist, breathing disturbances during sleep may be exacerbated. To identify SDB, sleep studies are commonly used to assess oxygen levels, heart rate, and breathing patterns. The objective of this research is to identify differences between patients with chronic respiratory diseases who have SDB and those who do not. This will be achieved by analysing sleep study data using a novel analytical approach. The aim is to determine whether this method can yield more detailed insights into the underlying pathophysiology of these conditions.

To assess the diagnostic accuracy of an exhaled breath VOC-assisted diagnostic artificial intelligence (AI) model in diagnose more pulmonary diseases.

The detection of exhaled nitric oxide (FeNO) represents a non-invasive, safe, and rapid approach for assessing endogenous nitric oxide (NO) levels within the airway. FeNO concentrations are closely associated with airway inflammation and hyperresponsiveness, and are currently recognized as biomarkers indicative of type II airway inflammation. Recent advancements in nitric oxide detection technology for both upper and lower airways, as well as for small and large airways, have provided significant insights for the diagnosis and management of conditions such as bronchial asthma, chronic cough, upper airway diseases, chronic obstructive pulmonary disease, and even rare airway disorders. Presently, FeNO measurement is frequently employed in the differential diagnosis and monitoring of airway inflammatory diseases. The FeNO test is conducted using a FeNO test analyzer. Internationally, FeNO detection analyzers utilize three primary methodologies: chemiluminescence, laser, and electrochemical techniques. Among these, chemiluminescence is regarded as the "gold standard" globally. However, due to technical constraints, this methodology has not been clinically accessible within domestic settings. In China, the electrochemical FeNO analyzer is predominantly utilized, characterized by its compact size and portability. Nonetheless, this method necessitates patient cooperation during inhalation and exhalation, rendering it impractical for individuals who are unable to comply, such as children, the elderly, and severely ill patients. Consequently, FeNO detection poses significant challenges for these populations in China, representing a notable clinical gap. The newly implemented technology employs an innovative domestic chemiluminescence FeNO analyzer, which is exclusively available in China. This analyzer, owing to its methodological advantages, is capable of obtaining FeNO detection values from patients' natural breathing patterns, facilitating rapid response and comprehensive FeNO assessment without requiring patient cooperation. This approach, referred to as the "Tidal-breathing of FeNO" enables the completion of FeNO assessments in patients who are unable to engage in inspiratory and expiratory maneuvers. This advancement is anticipated to enhance the diagnostic accuracy of airway inflammation in this demographic, thereby facilitating early diagnosis, precise treatment, and improved management of disease progression.

Bronchial asthma is a common respiratory disorder among children, worldwide. Asthma is characterized by chronic inflammation and remodeling of the airways induced by recurrent exposure to hypoxemia that leads to repeated tissue injury and repair. The interaction between respiratory diseases and cardiovascular function is complex . Cardiac dysfunction can be attributed to pulmonary hypertension (PH) secondary to recurrent hypoxia in patients with bronchial asthma. PH affects the pulmonary vasculature by releasing various cytokines leading to pulmonary vasoconstriction and enhancing the remodeling process with muscularization and proliferation of the vascular media and intima . Other hypotheses concluded that the exaggerated respiratory efforts may raise the intrathoracic pressure and increase right ventricle (RV) afterload and consequently RV hypertrophy and/or dilatation . Children with severe bronchial asthma can experience cor pulmonale later in life, but little is known about the early cardiac changes that might be present during childhood especially for mild or moderate persistent asthma. Some studies have reported right ventricular dysfunction as the earliest hemodynamic change among those cases . Other studies did not report these results and reported impaired systolic function of the left ventricle (LV) even before diastolic dysfunction . Insufficient control of BA, in turn, can cause the formation of various pathological conditions. For example, there are studies showing the risk of cardiac arrhythmias and conduction disorders in patients with uncontrolled BA due to functional changes or pathological remodeling of the myocardium . Atrial remodeling, which is the pathomorphological basis of serious supraventricular cardiac arrhythmias, has a more rapid progression with poor BA control and is formed as a result of excessive stretching of the atrial wall, as well as other adverse factors . The connection between BA and supraventricular arrhythmias, including atrial fibrillation (AF), was noted in studies by Cepelis et al. Available data indicate that in the adult population, cardiac arrhythmias are significantly more common in patients with BA than in those without it (9). The results of a Norwegian population study HUNT study, demonstrate that the risks of supraventricular arrhythmias and AF are increased in patients with an uncontrolled BA . Electrocardiography (ECG) is the universal screening method for assessing the state of the atrial myocardium and the conducting system of the heart. According to German et al. ECG analysis can make a significant input to the assessment of the risk of formation of supraventricular rhythm and conduction disorders. Therefore, the analysis of the atrial component of the ECG, and atrioventricular conduction in patients with BA is an important component of the management of these patients, especially in pediatric practice. Consequently, the study of the characteristics of the ECG and its supraventricular component in children with BA is relevan

Asthma is considered the most common chronic childhood disease and mainly affects children resident in urban areas. Asthma has been designated a serious public health problem due to the increase in its prevalence over the last two decades and the associated high health service costs in admissions and hospitalizations The cause of asthma is not yet completely understood, and there is no consensus about its etiology. A vast body of research emphasizes the role of genetic and environmental factors in the appearance of asthma, and a great deal of interest has recently emerged concerning the relationship between psychosocial factors and asthma morbidity Behavioural problems in children are generally described as "internalizing", which includes "anxiety, depressive, and somatic symptoms" or "externalizing", which includes "oppositional, hyperactive conduct". Both internalizing and externalizing problems can be experienced by healthy children with abnormal and "borderline" personality disorder, the latter referring to a mental illness marked by an ongoing pattern of varying moods, self-image, and behaviour

Bronchial asthma is a widespread chronic condition charactrized by inflammation and narrowing of airways, leading to repeateted episodes of breathlessness, wheezing and labored breathing.Breathing exercises help to manage hyperventilation often seen in asthmatic patients. To handle respiratory complications asthmatics are advised to practise nasal breathing techniques in conjunction with their prescribed medications.

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.

1. Evaluate the efficacy of 4 weeks of maintenance therapy with low-dose ICS/LABA versus as-needed low-dose ICS/LABA in newly diagnosed mild asthma patients. Assess the improvement in FEV1 from baseline over 4 weeks, and the impact on airway reversibility and inflammation levels. Identify the optimal patient population and treatment regimen for the medication. 2.

Compare 4 weeks of initial maintenance therapy with low-dose ICS/LABA followed by as-needed low-dose ICS/LABA therapy until 24 weeks. In the 24-week study, incorporate mobile lung function monitoring to dynamically assess large and small airway function parameters and clinical indicators. Explore the impact of early maintenance therapy with low-dose ICS/LABA followed by as-needed treatment on FEV1 improvement from baseline, acute exacerbation risk indicators, and airway inflammation, and develop a model to predict acute exacerbations.

While the bidirectional relationship between the lung and the right heart are well studied, the cardiopulmonary interactions between the lung and the left heart are largely unresearched and not well understood. However, in recent years, there is a growing evidence that partially explains the bidirectional interaction between COPD and left heart. Systemic inflammation with multiorgan involvement is thought to play a role in COPD as a systemic disease. Some therapeutic approaches to COPD also appear to influence these cardiopulmonary interactions. While understanding these interactions is very important for clinicians, scientific data are scarce. Cardiac magnetic resonance imaging (cardiac MRI) is the gold standard for assessing cardiac function and dimensions as well as myocardial inflammation. Despite this excellent suitability of cardiac MRI for the assessment of cardiovascular function, only few studies have investigated cardiac function and myocardial structure in patients with pulmonary disease using cardiac MRI. Such a study is therefore very important for understanding the effects of pulmonary disease and its management on the heart. The objective is to determine cardiac function in patients with pulmonary disease and to analyze the cardiovascular effects of the treatment of the pulmonary disease. Specifically, the following will be studied: * Using cardiac MRI: Cardiac function and volumes and indications of myocardial fibrosis and edema in patients with chronic pulmonary disease at the time of first diagnosis. * the vascular function of pulmonary arteries in these patients, also using cardiac MRI * the relationship between pulmonary function parameters and cardiac dysfunction to identify patients at increased risk, if applicable. * Echocardiographic assessment of left heart including strain analysis. * the course of these cardiovascular parameters (using cardiac MRI and echocardiography) 3-6 months after initiation of guideline-based therapy for pulmonary disease.
