Peripheral blood cell mitochondrial dysfunction in myelodysplastic syndrome can be improved by a combination of coenzyme Q10 and carnitine

Structural mitochondrial abnormalities and genetic aberrations in mitochondrial proteins have been known in Myelodysplastic syndrome (MDS), yet there is currently little data regarding MDS's metabolic properties and energy production cells. In the current study, we used state-of-the-art methods to assess OXPHOS in peripheral blood cells obtained from MDS patients and healthy controls. We then assessed the effect of food supplements- Coenzyme Q10 and carnitine on mitochondrial function and hematological response. We show here for the first time that there is a significant impairment of mitochondrial respiration in peripheral blood cells in low-risk MDS, which can be improved with food supplements. We also show that these supplements may improve the cytopenia and quality of life.
