          Abstract

          Introduction

          Statin-associated myalgia occurs in about 1–3% of patients in the medical literature. Plasma CoQ10 levels are reduced in patients undergoing statin.

          Objective

          The primary outcome was the detection of clinical symptoms and the perception of pain evaluated throughout specific questionnaires. The secondary outcome was the variation in lipid profile and the variation in safety parameters.

          Methods

          We enrolled 60 Caucasian patients, intolerant to statins. During the run-in period, patients underwent a 1-month wash-out period during which statins were stopped. At the end of the wash-out period, if CPK and/or transaminases returned within an acceptable range, statins were re-introduced at half of the previously taken dose. After one month, patients were randomized to take either a liquid CoQ10 supplement or a placebo for three months at 100 mg/day.

          Results

          The Clinical Index Score for myalgia assessment was lower after 3 months with CoQ10, while it did not change with the placebo. The VAS score was lower after 3 months of CoQ10 supplementation, while no variation was recorded with the placebo. In the group treated with the dietary supplement, CoQ10 plasma concentrations were inversely correlated with CPK levels, Clinical Index Score absolute values, and VAS.

          Conclusion

          The addition of CoQ10 with half dosage statin in patients with previous intolerance to statins improves the perception of clinical symptoms such as asthenia, myalgia or pain.

            An assessment by the Statin Muscle Safety Task Force: 2014 update.

            The National Lipid Association's Muscle Safety Expert Panel was charged with the duty of examining the definitions for statin-associated muscle adverse events, development of a clinical index to assess myalgia, and the use of diagnostic neuromuscular studies to investigate muscle adverse events. We provide guidance as to when a patient should be considered for referral to neuromuscular specialists and indications for the performance of a skeletal muscle biopsy. Based on this review of evidence, we developed an algorithm for the evaluation and treatment of patients who may be intolerant to statins as the result of adverse muscle events. The panel was composed of clinical cardiologists, clinical lipidologists, an exercise physiologist, and a neuromuscular specialist.

              High-dose statins and skeletal muscle metabolism in humans: a randomized, controlled trial.

              Myopathy, probably caused by 3-hydroxy-3-methylglutaryl-coenzyme A reductase inhibition in skeletal muscle, rarely occurs in patients taking statins. This study was designed to assess the effect of high-dose statin treatment on cholesterol and ubiquinone metabolism and mitochondrial function in human skeletal muscle. Forty-eight patients with hypercholesterolemia (33 men and 15 women) were randomly assigned to receive 80 mg/d of simvastatin (n = 16), 40 mg/d of atorvastatin (n = 16), or placebo (n = 16) for 8 weeks. Plasma samples and muscle biopsy specimens were obtained at baseline and at the end of the follow-up. The ratio of plasma lathosterol to cholesterol, a marker of endogenous cholesterol synthesis, decreased significantly by 66% in both statin groups. Muscle campesterol concentrations increased from 21.1 +/- 7.1 nmol/g to 41.2 +/- 27.0 nmol/g in the simvastatin group and from 22.6 +/- 8.6 nmol/g to 40.0 +/- 18.7 nmol/g in the atorvastatin group (P = .005, repeated-measurements ANOVA). The muscle ubiquinone concentration was reduced significantly from 39.7 +/- 13.6 nmol/g to 26.4 +/- 7.9 nmol/g (P = .031, repeated-measurements ANOVA) in the simvastatin group, but no reduction was observed in the atorvastatin or placebo group. Respiratory chain enzyme activities were assessed in 6 patients taking simvastatin with markedly reduced muscle ubiquinone and in matched subjects selected from the atorvastatin (n = 6) and placebo (n = 6) groups. Respiratory chain enzyme and citrate synthase activities were reduced in the patients taking simvastatin. High-dose statin treatment leads to changes in the skeletal muscle sterol metabolism. Furthermore, aggressive statin treatment may affect mitochondrial volume.
