"PROJECT":{"PROJECT_TITLE":"Methylprednisolone therapy induces differential metabolic trajectories in severe COVID-19 patients","PROJECT_TYPE":"Research","PROJECT_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.","INSTITUTE":"Federal University of Goiás","LAST_NAME":"Gardinassi","FIRST_NAME":"Luiz Gustavo","ADDRESS":"R. 235 s/n Institute of Tropical Pathology and Public Health","EMAIL":"luizgardinassi@ufg.br","PHONE":"+55 62 3209-6530"},

"COLLECTION":{"COLLECTION_SUMMARY":"The COVID-19 infected participants in this study were drawn from the MetCOVID study, a parallel, double blind, randomized, placebo-controlled Phase IIb clinical trial, that assessed the efficacy of MP in treating hospitalized patients with suspected SARS-CoV-2 infection. Individuals with COVID-19 were admitted at the Hospital e Pronto-Socorro Delphina Rinaldi Abdel Aziz, in Manaus, Western Brazilian Amazon. The hospital was the largest public reference unit for the treatment of severe COVID-19 cases in the city. After confirmation of SARS-CoV-2 infection by RT-qPCR testing of nasopharyngeal swabs, blood was collected from patients and the separated plasma was stored at -80oC. The plasma samples were collected at the day of inclusion (D1) before treatment, and day five (D5), day seven (D7), day eleven (D11), and day fourteen (D14) after the start of treatment for metabolomic analysis.","SAMPLE_TYPE":"Blood (plasma)"},

"TREATMENT":{"TREATMENT_SUMMARY":"The participants were administered with either intravenous sodium succinate MP (0.5 mg/kg) or placebo (saline solution) twice daily for 5 days. As per hospital protocol, all patients meeting acute respiratory distress syndrome criteria also preemptively received intravenous ceftriaxone (1g twice daily for 7 days) plus azithromycin (500 mg once a day for 5 days) or clarithromycin (500 mg twice daily for 7 days), starting on Day 1. At inclusion, adult patients were excluded if they had a history of hypersensitivity to MP, were living with human immunodeficiency virus or AIDS, had a history of chronic use of corticosteroids or immunosuppressive agents, were pregnant or breastfeeding, or had decompensated cirrhosis or chronic renal failure."},

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 high-resolution mass-spectrometry was obtained under full MS/dd-MS2 mode. The mass range in the full MS scanning experiments was m/z 80-1200. The max IT was set at 200 ms, and AGC target was set at 1 x 106. For fragmentation acquisition, the top 5 (TopN, 5, loop count 5) most abundant precursors were sequentially transferred into the C-Trap (AGC target 1 x 105; max IT 50 ms) for collision. The collision energy for target analytes was 20, 30 and 35 eV.
