Lipidomic and Metabolomic Changes in Community-acquired and COVID-19 Pneumonia

Abstract This prospective observational study compared the 1H NMR blood lipidomes and metabolomes of 71 community-acquired pneumonia (CAP) patients, 75 COVID-19 pneumonia patients, and 75 healthy controls (matched by age and sex) to identify potential biomarkers and pathways associated with respiratory infections. Both pneumonia groups had comparable severity indices, including mortality, invasive mechanical ventilation, and […]

Investigating the Link between Intermediate Metabolism, Sexual Dimorphism, and Cardiac Autonomic Dysfunction in Patients with Type 1 Diabetes

Abstract Sexual dimorphism influences cardiovascular outcomes in type 1 diabetes (T1D), with women facing a higher relative risk of macrovascular events compared to men, especially after menopause. This study hypothesizes that abnormalities in intermediate metabolism may be associated with cardiac autonomic neuropathy (CAN) in T1D. We aim to assess low molecular weight metabolites (LMWM) as […]

Identification of a molecular signature associated with covid-19 severity using a comprehensive 1H-NMR serum metabolomics profiling strategy

Abstract Background and Aims:Atherogenic dyslipidemia together with specific pro-inflammatory profiles have been identified as markers of severe adverse outcomes in COVID-19 disease. This study aims to evaluate nuclear magnetic resonance (NMR)-based metabolomics combined with machine learning algorithms as a strategy to identify a molecular signature associated with poor CoVID-19 prognosis.

Differential analysis of lipoprotein and glycoprotein profiles in bacterial infections and COVID-19 using proton NMR and machine learning

Abstract Methods We obtained sera from 124 patients with COVID-19, 50 patients with catheter-related bacterial infections, and 50 healthy volunteers. Results were interpreted using machine learning. Results COVID-19 patients had bigger and more abundant VLDL particles than the control group and higher VLDL-cholesterol and VLDL-triglyceride concentrations. Patients with bacterial infections showed similar trends, but differences […]
