Special Issue Information

Dear Colleagues,

Metabolomics, the comprehensive analysis of small molecules in biological samples, has emerged as a powerful tool in the field of pulmonary medicine such as chronic obstructive pulmonary disease (COPD), asthma, pulmonary fibrosis, Sarcoidosis, lung cancer, and viral and bacterial pneumonia. Pulmonary diseases encompass a wide range of conditions that are characterized by complex pathophysiological processes involving inflammation, oxidative stress, tissue remodeling, and metabolic dysregulation. One of the key rationales for utilizing metabolomics in pulmonary diseases is the ability to capture the dynamic metabolic changes occurring in the lungs and systemic circulation. Metabolites represent the end products of cellular metabolism and reflect the functional state of cells and tissues. By analyzing the global metabolic profile, metabolomics can provide a snapshot of the metabolite alterations associated with pulmonary diseases that can unravel dysregulated metabolic pathways in different lung conditions. This holistic approach allows for the identification of novel biomarkers for early diagnosis, disease classification, and insights into the molecular processes driving disease progression. Using metabolomics, the accurate clustering of pulmonary diseases can facilitate personalized medicine approaches that may hold great promise for improving treatment outcomes, minimizing side effects, and enhancing patient care in pulmonary disease. The scope of this Special Issue includes preclinical and clinical research in the field of metabolomics in pulmonary diseases. The Special Issue welcomes original articles, reviews, and perspectives that contribute to understanding metabolic alterations, diagnostics and prognostics biomarker discovery and stratification of diseases. We encourage submissions of papers using various metabolomics platforms including mass spectrometry, nuclear magnetic resonance and other analytical techniques on human clinical samples, animal models, and cell cultures. This Special Issue aims to provide an opportunity for researchers and experts in the field to share their new findings, methods and ideas about metabolomics and lung diseases.

The popularity of e-cigarettes (vaping) has soared, creating a public health crisis among teens and young adults. Chronic vaping can induce gut inflammation and reduce intestinal barrier function through the production of the proinflammatory molecule hydrogen sulfide (H2S). This is particularly concerning for people with HIV (PWH) as they already face impaired immune function and are at a higher risk for metabolic dysregulation, diabetes, and chronic liver disease. Furthermore, PWH experience unhealthy behaviors, making it crucial to understand the systemic metabolic dysregulation and pathophysiological mechanisms associated with vaping in this population. Here, we employed liquid chromatography–mass spectrometry (LC-MS)-based metabolomics to investigate the upper respiratory, circulation, and gut metabolic profiles of PWH who vape (n = 7) and smoke combustible tobacco/marijuana (n = 6) compared to control participants who did not vape or smoke (n = 10). This hypothesis-generating exploratory study revealed systemic alterations in purine, neurotransmitter, and vitamin B metabolisms and tissue-specific changes in inflammatory pathways and cryptic sulfur cycling associated with vaping and combustible tobacco/marijuana smoking in PWH. In addition, this study provides the first link between microbial-derived metabolite 2,3-dihydroxypropane-1-sulfonate (DHPS) and vaping/smoking (tobacco and marijuana)-induced metabolic dyshomeostasis in the gut. These findings highlight the importance of identifying the full biological and clinical significance of the physiological changes and risks associated with vaping. Full article

Maternal pathological conditions such as infections and chronic diseases, along with unexpected events during labor, can lead to life-threatening perinatal outcomes. These outcomes can have irreversible consequences throughout an individual’s entire life. Urinary metabolomics can provide valuable insights into early physiological adaptations in healthy newborns, as well as metabolic disturbances in premature infants or infants with birth complications. In the present study, we measured 180 metabolites and metabolite ratios in the urine of 13 healthy (hospital-discharged) and 38 critically ill newborns (admitted to the neonatal intensive care unit (NICU)). We used an in-house-developed targeted tandem mass spectrometry (MS/MS)-based metabolomic assay (TMIC Mega) combining liquid chromatography (LC-MS/MS) and flow injection analysis (FIA-MS/MS) to quantitatively analyze up to 26 classes of compounds. Average urinary concentrations (and ranges) for 167 different metabolites from 38 critically ill NICU newborns during their first 24 h of life were determined. Similar sets of urinary values were determined for the 13 healthy newborns. These reference data have been uploaded to the Human Metabolome Database. Urinary concentrations and ranges of 37 metabolites are reported for the first time for newborns. Significant differences were found in the urinary levels of 44 metabolites between healthy newborns and those admitted at the NICU. Metabolites such as acylcarnitines, amino acids and derivatives, biogenic amines, sugars, and organic acids are dysregulated in newborns with bronchopulmonary dysplasia (BPD), asphyxia, or newborns exposed to SARS-CoV-2 during the intrauterine period. Urine can serve as a valuable source of information for understanding metabolic alterations associated with life-threatening perinatal outcomes. Full article
