Nowadays, the COVID-19 epidemic causes stress not only to healthy people but also to people with unhealthy conditions. Excess psychological stress (either in quality, quantity, frequency, and/or duration) could push susceptible individuals to ultimately develop clinical asthma. Depression was significantly associated with asthma interference with daily activities, breathlessness, night symptoms, use of bronchodilators, and poor compliance with medical treatment. Covid-19 pandemic induced the countries around the world to require from its citizens not to ask for health care support rather than in emergency situations and through utilizing telemedicine. This action aims to control spreading the infection with viruses as well as to reduce the workload on the healthcare providers. Although asthma is not listed as one of the chronic conditions that might complicate coronavirus infections, asthma people might have a high-stress level that might induce their asthma attack which consequentially reflects on their quality of life. People with asthma have a unique experience rather than people with other health conditions during COVID-19. Patients with asthma experience a lot of stressors that might induce asthma and impaired their HRQOL such as overuse of antiseptic substances, stay home with a sedentary lifestyle, the sudden shift to telemedicine, and electronic work from home. Also, as a result of the similarity of asthma symptoms with coronavirus symptoms, the patient might have a continuous sense of uncertainty that s/he is infected with the COVID-19 virus, and this suspicion can increase the psychological overburden on these patients. Therefore, all these stressors should be evaluated to recognize their health needs and the kind of social and health support that should be provided to them during the pandemic time. Also, Identifying the predictors of HRQOL among patients with asthma during the pandemic of COVID-19 is urgently required.

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

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. Based on a comprehensive evaluation of pulmonary function parameters (including large airway parameters: FEV1, FEV1/FVC; peak flow: PEF; small airway parameters: FEF25%, FEF50%, FEF75%, MMEF) and airway inflammation levels, explore biomarkers that can effectively predict the efficacy of maintenance therapy with low-dose ICS/LABA in newly diagnosed mild asthma patients. 3. 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.

NCT06141161
Asthma is a significant public health threat, affecting more than 300 million individuals globally. Asthma is classified as a non-communicable disease and leads to reduced quality of life, poor physical functioning and reduced emotional well-being. The impact of this disease can be widespread and extends beyond the person living with the disease, affecting the lives of their family members, carers, communities and the health care system (1). Asthma is a variable chronic respiratory condition. It is characterized by symptoms of wheeze, cough, chest tightness, dyspnea and backed by variable airflow limitation, airway inflammation and airway hyper-responsiveness (AHR). The severity of asthma varies considerably, both between individuals and within individuals over time. Some people may have intermittent asthma and others may experience severe, potentially life-threatening disease (2, 3,4).
