Coenzyme Q10 on Athero-thrombosis in APS Patients
Conditions
Brief summary
The study will be performed on 50 APS (antiphospholipid Syndrome) patients, which will be randomized to receive either CoQ10 (200mg/day) or placebo for one month. Blood will be drawn at time 0 and at the end of the treatment. Studies will be conducted in plasma and purified leukocytes from APS. Design: 1) Study of endothelial function: 2) Analysis of changes operated on various prothrombotic/proinflammatory parameters and their associated intracellular signalling. 3) Analysis of mitochondrial ultra structure and activity; mitochondrial antioxidant system characterization; Expression levels and activity of transcription factors/proteins involved in oxidative stress (Foxo 3, NFkB, Nrf2), Quantification of CoQ10 (Coenzyme Q10). 4) Biomarkers of oxidative stress. 5) miRNAs microarrays, RT-PCR validation and correlation/association studies. 6) Induction of over-expression of miRNAs of interest; luciferase constructs. 7)Studies of methylation.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in endothelial function in vivo | 0 weeks, 4 weeks, 8weeks, 12weeks | Study of the endothelial function in vivo. Variations in capilar blood flow of the skin will be analyzed by noninvasive Doppler laser fluorimetry using a Periflux 5000 equipment. The study will be performed on 50 APS (antiphospholipid Syndrome) patients. Patients will be randomized to CoQ10 or placebo group. Treatments will be given for 1 month, according to a randomized and crossover design (with wash-out periods of four weeks) Blood will be drawn at time 0, at the end of treatment, and after three months of the end of treatment. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in Tissue factor | 0 weeks, 4 weeks, 8 weeks, 12 weeks | Parameters related to inflammation and thrombosis in cells measure at mRNA and VEGF (Vascular Endothelial Growth Factor) in serum/plasma and cells. The study will be performed on 50 APS (antiphospholipid Syndrome) patients. Patients will be randomized to CoQ10 or placebo group. Treatments will be given for 1 month, according to a randomized and crossover design (with wash-out periods of four weeks) Blood will be drawn at time 0, at the end of treatment, and after three months of the end of treatment. |
