Presence of auto-reactive antibodies in Long Term COVID-19 |
Investigation of auto-reactive antibodies at baseline compared to healthy controls (biobank samples), by immunohistochemistry and enzyme-linked immunosorbent assay (ELISA) against tissue proteins. |
Blood samples week 6, 10, 16 and 20 after enrollment |
|
| Other |
Assessment of levels of Coenzyme Q10 plasma and PBMC in Long Term COVID-19 patients treated with Coenzyme Q10 versus placebo. |
Assessment of baseline levels Coenzyme Q10 in plasma (nmol/L) and in PBMC (picogram / mg protein) , measured by High Performance Liquid Chromatography (HPLC), as this parameter previously has been associated with fatigue. |
Blood samples after 6 weeks of treatment and after 6 weeks of placebo. |
|
| Other |
Quantitative proteomics in peripheral blood mononuclear cells (PBMCs) from Coenzyme Q10 treated patients versus placebo. |
Relative quantification of the approximately four thousand most abundant proteins is performed by liquid chromatography (LC) tandem mass spectrometry (MS/MS). The quantitative signal is the MS peak intensities, with arbitrary scale. Statistically differentially regulated proteins are filtered out and described specifically. |
Blood samples week 6, 10, 16 and 20 after enrollment |
|
| Other |
Assessment of cellular metabolic activity in PBMCs from Coenzyme Q10 treated patients by Seahorse analysis versus placebo. |
Differential analysis of metabolic activities (Seahorse) in PBMCs from the treated patients versus placebo. Extracellular Acidification Rate (ECAR) (picomoles protons / minute) and Oxygen Consumption Rate (OCR) (picomoles O2 per minute) are measured to estimate glycolytic rate and respiration rates in the isolated PBMCs, respectively. |
Blood samples week 6, 10, 16 and 20 after enrollment |
|
| Other |
Analysis of oxidative stress marker 8-isoprostane in Long Term COVID-19 patients treated with Coenzyme Q10 versus placebo. |
Differential analysis of plasma samples from CoQ10 treated patients versus placebo, with respect to the oxidative stress marker 8-isoprostane by ELISA assay measured in picomoles 8-isoprostane per mL. |
Blood samples week 6, 10, 16 and 20 after enrollment |
|
| Other |
Assessment of presence of cytokines in Long Term COVID-19 patients treated with Coenzyme Q10 versus placebo. |
Differential analysis of plasma samples from CoQ10 treated patients versus placebo with Luminex to assess presence of cytokines measured as picomole cytokine / mL. |
Blood samples week 6, 10, 16 and 20 after enrollment |
|
| Other |
Analysis of metabolites of the kynurenic pathway in Long Term COVID-19 patients treated with Coenzyme Q10 versus placebo. |
Differential analysis of plasma samples from CoQ10 treated patients versus placebo with respect to metabolites of the kynurenic pathway by LC-MS/MS measured in nanomole per mL. |
Blood samples week 6, 10, 16 and 20 after enrollment |
