| Study Title | Methylprednisolone therapy induces differential metabolic trajectories in severe COVID-19 patients |
| Study Summary | Corticosteroids have become a choice for managing severe COVID-19, but the molecular mechanisms behind the response after corticosteroid administration remain incompletely understood. In order to unravel this, comparisons between temporal metabolic profiles in the plasma samples of methylprednisolone (MP) - and placebo-treated COVID-19 patients were performed at different time points. The patient plasma samples used were obtained from a double blind, randomized, placebo-controlled Phase IIb clinical trial performed on severe COVID-19 patients in the Brazilian Amazon where the patients received placebo or 0.5 mg/kg MP intravenously twice daily for five days. The MP treatment reduced the number of metabolites in the plasma of patients during follow-up. The longitudinal changes in the MP-group was in eight metabolic pathways related to steroid hormones and eicosanoids. Direct comparison between the two groups, revealed differences at baseline, which peaked five days after initiation of MP treatment. The metabolic pathways differing between the two groups over time included galactose metabolism, glucose and gluconeogenesis, N-glycan metabolism, and prostaglandin formation from arachidonate. Deoxy-galactose, prostaglandin H2, sphingosine, and sphinganine exhibited differential trajectories by day 14 after initiating the MP treatment. Survival of MP-treated COVID-19 patients was associated with modulation of tryptophan metabolism. Network analysis revealed that MP treatment is highly associated with alterations in pathways reflecting eicosanoid metabolism, such as arachidonic acid and prostaglandins. Curiously, there is crosstalk between metabolomics, biochemistry and cytokine components. Treatment of systemic and inflammatory conditions induced by SARS-CoV-2 viral infections with methylprednisolone modulates metabolic activity associated with tryptophan and inflammatory lipids. |

| Chromatography Summary: | The binary mobile phases were water 0.5% formic acid with 5 mM of ammonium formate (A), and acetonitrile (B). Their gradient elution started with 20% (B) for 5 min, then linearly increased to 100% (B) in 30 min and kept constant for 8 min in 100% (B). The eluent was restored to the initial conditions in 4 minutes to re-equilibrate the column and held for the remaining 8 minutes. The flow rate was kept at 0.5 mL min-1. The injection volume for analysis was 3 μL, and the column temperature was set at 35 °C. |
