Study Title | Metabolomics of patients with Plasmodium vivax malaria |
Study Summary | Background: Malaria is the leading parasitic disease worldwide, with P. vivax being a major challenge for its control. Several studies have indicated metabolomics as a promising tool for combating the disease. Objective: The study evaluated plasma metabolomic profiles of patients with recurrent and non-recurrent P. vivax malaria in the Brazilian Amazon. Methods: Metabolites extracted from the plasma of P. vivax-infected patients were subjected to LC-MS analysis. Untargeted metabolomics was applied to investigate the metabolic profile of the plasma in the two groups. Results: Overall, 51 recurrent and 59 non-recurrent patients were included in the study. Longitudinal metabolomic analysis revealed 52 and 37 significant metabolite features from the recurrent and non-recurrent participants, respectively. Recurrence was associated with disturbances in eicosanoid metabolism. Comparison between groups suggest alterations in vitamin B6 (pyridoxine) metabolism, tyrosine metabolism, 3-oxo-10-octadecatrienoate β-oxidation, and alkaloid biosynthesis II. Integrative network analysis revealed enrichment of other metabolic pathways for the recurrent phenotype, including the butanoate metabolism, aspartate and asparagine metabolism, and N-glycan biosynthesis. Conclusion: The metabolites and metabolic pathways predicted in our study suggest potential biomarkers of recurrence and provide insights into targets for antimalarial development against P. vivax. |

Sample Preparation:
Sampleprep ID: | SP003280 |
Sampleprep Summary: | Metabolites were extracted from 150 µL of sample (plasma EDTA), which was mixed with acetonitrile (2:1, v/v; -5 °C) and centrifuged at 15,000 rpm for 15 min to remove proteins. Stable isotopes caffeine-¹³C3, tyrosine-15N and progesterone-d9 were used as internal standards. |
