INFLUENCE OF COENZYME Q10 ON HYPERLIPIDEMIA INDUCED IN MICE

Background and objective: Oxidative stress and inflammation are key parameters in developing metabolic disorders. Hence, antioxidant intake might be an appropriate approach. Several studies have evaluated the effect of coenzyme Q10 (CoQ10) supplementation on lipid profile among patients with metabolic diseases, though findings are controversial. The aim of this systematic review and meta-analysis was to determine the effects of CoQ10 supplementation on lipid profile in patients with metabolic disorders. Methods: We searched PubMed, EMBASE, Web of Science and Cochrane Library databases until July 2017. Prospective clinical trials were selected assessing the effect of CoQ10 supplementation on different biomarkers. Two reviewers independently assessed the eligibility of studies, extracted data, and evaluated the risk of bias of included studies. A fixed- or random-effects model was used to pool the data, which expressed as a standardized mean difference with 95% confidence interval. Heterogeneity was measured using a Q-test and with I2 statistics. Results: A total of twenty-one controlled trials (514 patients and 525 controls) were included. The meta-analysis indicated a significant reduction in serum triglycerides levels (SMD -0.28; 95% CI, -0.56, -0.005). CoQ10 supplementation also decreased total-cholesterol (SMD -0.07; 95% CI, -0.45, 0.31), increased LDL- (SMD 0.04; 95% CI, -0.27, 0.36), and HDL-cholesterol levels (SMD 0.10; 95% CI, -0.32, 0.51), not statistically significant. Conclusion: CoQ10 supplementation may significantly reduce serum triglycerides levels, and help to improve lipid profiles in patients with metabolic disorders. Additional prospective studies are recommended using higher supplementation doses and longer intervention period.

Liver Tissues

Background: Busulfan (Bu) is an anticancer drug with a variety of adverse effects for cancer patients. Oxidative stress has been considered as a common pathological mechanism and it has a key role in the initiation and progression of liver injury by Bu. Aim: The study aimed to evaluate the antioxidant impact of L-Carnitine and Coenzyme Q10 and their protective role against oxidative stress damage in liver tissues. Methods and Material: Thirty-six albino rats were divided equally into six groups. G1 (con), received I.P. injection of DMSO plus 1 ml of distilled water daily by oral gavages; G2 (Bu), received I.P. injection of Bu plus 1 ml of the distilled water daily; G3 (L-Car), received 1 ml of L-Car orally; G4 (Bu + L-Car) received I.P. injection of Bu plus 1 ml of L-Car, G5 (CoQ10) 1 ml of CoQ10 daily; and G6 (Bu + CoQ10) received I.P. injection of Bu plus 1 ml of CoQ10 daily. Results: The recent data showed that Bu induced significant (P<0.05) elevation in serum ALT, AST, liver GSSG, NO, MDA and 8-OHDG, while showing significant (P<0.05) decrease in liver GSH and ATP. On the other hand, L-Carnitine and Coenzyme Q10 ameliorated the negative effects prompted by Bu. Immunohistochemical expression of caspase-3 in liver tissues reported pathological alterations in Bu group while also showed significant recovery in L-Car more than CoQ10. Conclusion: L-Car, as well as CoQ10, can enhance the hepatotoxic effects of Bu by promoting energy production in oxidative phosphorylation process and by scavenging the free radicals.

There is a dramatic need for extensive research into the predictors of severe infection with SARS-CoV2 and therapeutic options for infected people. People who suffer from severe illness and higher mortality display a pattern of having specific co-morbidities (diabetes, obesity, hypertension) and are of higher age. Recent research has described methods of viral entry via receptors (ACE2, TMPRSS2) and the hyper-inflammatory state often associated with severe illness (increase in interleukins, increase in TNF-alpha). These discoveries have led to the research of currently available and developing therapies, that are helpful to patients. Deficiencies of specific vitamins and other endogenous molecules of the body should be examined to understand if a pattern exists among the people most severely affected. Coenzyme Q10 (CoQ10) is a fat-soluble substance ubiquitously expressed throughout the body that is important for the generation of ATP and mediation of inflammatory disease. CoQ10 faces a decline with increasing age, genetic predispositions, and ingestion of exogenous compounds that could reduce the level of CoQ10. Deficiencies and subsequent supplementation with CoQ10 recently has displayed encouraging results for the improvement of a wide variety of diseases. This manuscript is significant as it points to a potential relationship of CoQ10 and the population suffering from severe illness of COVID-19, and further encourages the need for research into measuring the levels of CoQ10 and vitamins to understand if levels predict severe illness and mortality. This could offer new avenues into research in combating this pandemic and potentially future therapeutic options.
