Respiratory infections exert a profound influence on the composition of breath biomarkers, offering invaluable insights into the physiological and pathological processes underlying these infections. Breath biomarkers, comprising a diverse array of volatile organic compounds (VOCs) and trace gases, reflect the metabolic activities and biochemical pathways within the human body. Their alteration in response to respiratory infections can serve as a non-invasive diagnostic tool, providing timely and crucial information for clinical intervention. One of the primary consequences of respiratory infections on breath biomarkers is the elevation of inflammation-related compounds. Inflammatory mediators, such as cytokines and chemokines, instigate a cascade of events that culminate in the release of VOCs like isoprene, acetone, and ethane. These compounds are indicative of oxidative stress and lipid peroxidation, which are characteristic features of inflammation. Elevated levels of isoprene, for instance, have been observed in various respiratory infections, including pneumonia and bronchitis, underscoring its potential as a reliable biomarker for assessing the severity and progression of these conditions. Furthermore, alterations in the composition of breath biomarkers reflect changes in the respiratory microbiota during infections. The microbial communities residing in the respiratory tract contribute to the production of specific VOCs, including acetone, ethanol, and methanol. Shifts in the abundance and diversity of these microbes can lead to discernible changes in breath composition. For instance, an overgrowth of pathogenic bacteria in conditions like bacterial pneumonia can result in an increase in VOCs associated with bacterial metabolism, providing valuable information for the identification of the causative agent. Respiratory infections also impact the concentration of exhaled nitric oxide (NO), a pivotal biomarker in assessing airway inflammation. Elevated levels of exhaled NO have been correlated with conditions like asthma and viral respiratory infections. The up-regulation of inducible nitric oxide synthase (iNOS) in response to infection leads to increased production of NO, reflecting the activation of inflammatory pathways. Monitoring exhaled NO levels can therefore aid in the diagnosis and management of respiratory infections, enabling tailored therapeutic approaches. In addition to inflammation- related changes, respiratory infections can modulate the levels of specific VOCs associated with cellular damage and repair mechanisms. For instance, alterations in lipid metabolism and oxidative stress during infections lead to the release of aldehydes, such as hexanal and pentanal, which serve as indicators of cellular damage. Conversely, the presence of antioxidants like alpha-tocopherol can reflect the body’s efforts to mitigate oxidative stress. These dynamic changes in breath biomarkers provide valuable information about the host’s response to infection and can guide treatment strategies. Moreover, the impact of respiratory infections on breath biomarkers extends beyond immediate diagnostic implications, offering potential insights into the long-term consequences of these infections. Persistent alterations in breath composition may serve as prognostic indicators for the development of chronic respiratory conditions or other associated comorbidities. For instance, prolonged elevation of inflammation-related VOCs may predispose individuals to the development of respiratory disorders like chronic obstructive pulmonary disease (COPD) or interstitial lung disease. The respiratory infections exert a profound influence on breath biomarkers, reflecting the dynamic interplay between host responses and pathogen-induced changes in the respiratory tract. These alterations encompass a wide range of VOCs, including inflammation-related compounds, microbial metabolites, and markers of cellular damage and repair.
