Case ReportsMitochondrial dysfunction in skin biopsies and blood mononuclear cells from two cases of fibromyalgia patients.
Coenzyme Q(10) (CoQ(10)) is an essential electron carrier in the mitochondrial respiratory chain and a strong antioxidant. Signs associated with skin alteration and mitochondrial dysfunction have been observed in patients with fibromyalgia (FM). The aim of this study was to analyze CoQ(10) levels, mitochondrial dysfunction, and oxidative stress in plasma, blood mononuclear cells, and skin biopsies from FM patients. ⋯ In our patients, mitochondrial dysfunction and CoQ(10) deficiency are present in several tissues. These results may contribute to the understanding of the pathophysiology of FM, and, moreover, CoQ(10) deficiency could represent a good marker for the diagnosis of FM.
