Objectives: Multiple sclerosis (MS) is the chronic inflammatory and demyelinating disorder of central nervous system which is accompanied with disability and negative life style changes such as fatigue and depression. The aim of this study is to investigate the effect of coenzyme Q10 (CoQ10) supplementation on fatigue and depression in patients with MS.Methods: We performed a randomized, double-blinded, placebo-controlled trial to determine the effect of CoQ10 supplement (500?mg/day) vs. placebo for 12?weeks. Fatigue symptoms were quantified by means of fatigue severity scale (FSS) and the Beck depression inventory (BDI) was used to assess depressive symptoms.Results: A significant decrease of FSS was observed in CoQ10 group during the intervention (P?=?0.001) and significant increase of FSS change was observed within placebo group (P?=?0.001). Repeated measure analysis of variance showed a significant time-by-treatment interaction for FSS (baseline 41.5?±?15.6 vs. endpoint 45?±?13.6; F1,45?=?55.23, P?<?0.001, η2?=?0.56) and BDI (baseline 17.8?±?12.2 vs. endpoint 20.4?±?11.4; F1,45?=?40.3, P?<?0.001, η2?=?0.48), indicating significant decrease of FSS and BDI in CoQ10 group compared to placebo group.Conclusion: Our study suggests that CoQ10 supplementation (500?mg/day) can improve fatigue and depression in patients with multiple sclerosis. 相似文献

Cryopreservation-induced oxidative stress (OS) may lead to lipid peroxidation, which may be responsible for decreased cell survival rate. Coenzyme Q10 (CoQ10) as a potent antioxidant may improve cell viability by neutralizing OS. In this study, oxidative lipid injury following the vitrification of preantral follicles was investigated. The effects of CoQ10 treatment on the malondialdehyde (MDA) levels, lipid peroxidation products, and activities of enzymatic and nonenzymatic antioxidants of vitrified preantral follicles were also studied. Preantral follicles were isolated from immature mouse ovaries and were vitrified. After warming, these follicles were cultured with or without CoQ10 for four days. The levels of total antioxidant capacity (TAC) and MDA, as well as the activities of superoxide dismutase (SOD), glutathione peroxidase (GPX), and catalase (CAT), were assessed at 0, 24, 48, 72, and 96 hours of culture period. The MDA level in the vitrified preantral follicles was higher than that in the fresh groups. By contrast, the MDA level was significantly lower in the groups with CoQ10 treatment than in those without this treatment during cultivation. The TAC level was higher in the fresh preantral follicles than in the vitrified groups. The rates were also higher in the CoQ10-treated groups than in those without this treatment. The activities of SOD, GPX, and CAT were also significantly higher in the fresh groups than in the vitrified groups, especially in the groups with CoQ10 treatment than in those without this treatment. Lowering the vitrification-induced lipid peroxidation of preantral follicles by CoQ10-supplemented maturation medium may be mediated by increasing SOD, GPX, and CAT activities and TAC level during cultivation. 相似文献

Backgrounds and aims: Migraine and inflammation are correlated. Coenzyme Q10 (CoQ10) as an anti-inflammatory agent has shown useful effects in other diseases. The present study aimed to assess the effect of CoQ10 supplementation on inflammation and clinical features of migraine.Methods: This randomized double-blind placebo-controlled clinical trial was conducted among 45 non-menopausal women aged 18–50 years, diagnosed for episodic migraine according to the International Headache Society. After one month run-in period, subjects received CoQ10 (400 mg/day CoQ10, n = 23) or placebo (wheat starch, n = 22) for three months. All the patients got prophylactic medication too. Serum CoQ10 concentration, Calcitonin gene-related peptide (CGRP), interleukin (IL)-6, IL-10 and tumor necrosis factor-α (TNF-α) were measured at the beginning and end of the study.Results: CoQ10 supplementation reduced CGRP and TNF-α significantly (p = 0.011 and p = 0.044, respectively), but there were no significant differences in serum IL-6 and IL-10 between the two groups. Significant increase in serum CoQ10 levels was evident with CoQ10 therapy (P < 0.001). A significant improvement was found in frequency (p = 0.018), severity (p = 0.001) and duration (p = 0.012) of migraine attacks in CoQ10 group compared to placebo.Conclusion: CoQ10 supplementation may decrease CGRP and TNF-α with no favorable effects on IL-6 and IL-10 in patients with migraine. 相似文献
