ABSTRACT = {<i>Helicobacter pylori</i> infection has been significantly linked to Peptic Ulcer Disease and Gastric Cancer.
Metabolomic fingerprinting may offer a principal way of early diagnosis and to understand the molecular mechanism
of <i>H. pylori</i>-induced pathogenicity. The rationale of the study is to explore the underlying distinct metabolic
mechanisms of H. pylori-induced PUD and to identify potential biomarkers for disease diagnosis and associated risks
using Gas chromatography/mass spectrometry. GC/MS-based analytical method was used to compare metabolic
profiles of healthy controls (N = 20) and peptic ulcer patients (N = 45). Acquired metabolomic data were analyzed by
constructing a diagnostic model using principal component analysis and a non-parametric two-tailed paired Wilcoxon
analysis to identify disease-specific metabolic biomarkers. A total of 75 low-molecular-weight endogenous metabolites
were detected during comparative metabolomic analysis of PUD vs. healthy gut tissues, among which 16 metabolites
are being proposed to be diagnostic markers of Human PUD. Perturbations related to amino acids, carbohydrates,
fatty acids, organic acids, and sterol metabolism were significantly revealed during this differential metabolomic
profiling. Results convincingly suggest that metabolic profiles can contribute immensely in early diagnosis of the
disease and understanding molecular mechanisms of disease progression for predicting novel drug targets for
prophylactic and anaphylactic measures.},
