| Abstract | Severe sepsis (SS) remains among the leading causes of death in both developed and developing countries. There is an urgent need for accurate biomarkers for early diagnosis of SS. Non-targeted mass-spectrometry was used to characterize sensitive and economical peripheral biomarker(s) associated with the serum metabolome from SS patients. In this study, serum samples were obtained from healthy controls and age-matched patients with SS. Multivariate statistical analysis was performed, and the metabolites identified were studied in relation to subsequent intervention procedures by receiver operating characteristic curve analysis. Metabolic differences among SS and control subjects were identified based on orthogonal signal correction-partial least squares discriminant analysis. Sphingosine, 5-methylcytidine, 3-dehydrocarnitine, 4-acetamido-2-aminobutanoic acid and phenyllactic acid in the SS subjects were significantly different from the controls. Three metabolites comprising sphingosine, 5-methylcytidine and 3-dehydrocarnitine were selected as candidate biomarkers and validated in separate, independent patient cohorts. These metabolite markers hold great potential for further development of SS early diagnostic markers. These findings suggest mass-spectrometry serum metabolomics may possess great potential for early diagnosis of SS patients. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
