Pulmonary Condensate: Non-invasive Evaluation of Pulmonary Involvement in Asthma and Cystic Fibrosis.

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 Use of Entropy to Assess Sleep Disordered Breathing in Chronic Respiratory Disease

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.

FeNO Detection in Asthma Diagnosis: A New Technology Approach

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.

Echo and Electrocardiographic Findings in Children With Bronchial Asthma At Sohag University Hospital

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
