Assessing nitric oxide components in asthma and COPD patients

The Clinical Value of the Nitric Oxide System Components in Asthma and Chronic Obstructive Pulmonary Disease

Observational Ryazan State Medical University · NCT04456491

This study is trying to see if measuring certain nitric oxide levels in people with asthma and COPD can help us understand their condition better and find new ways to prevent flare-ups.

What this trial studies

This study aims to evaluate the levels of nitric oxide metabolites, L-arginine, arginase-1, and asymmetric dimethylarginine in patients diagnosed with bronchial asthma and chronic obstructive pulmonary disease (COPD). By observing these biomarkers, the research seeks to enhance the understanding of disease prognosis and potentially identify new methods for predicting and preventing exacerbations. The study focuses on the role of nitric oxide in respiratory diseases, which are characterized by persistent inflammation and systemic dysfunction. The findings could contribute to personalized medicine approaches in managing these conditions.

Who should consider this trial

Good fit: Ideal candidates include men and women aged 18 to 70 with a diagnosis of asthma or COPD according to current guidelines.

Not a fit: Patients with severe cardiovascular issues, liver dysfunction, or significant renal impairment may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved methods for predicting and managing asthma and COPD exacerbations.

How similar studies have performed: While the approach of using nitric oxide metabolites as biomarkers is established, the specific application in this context is relatively novel.
