Effect of Statin Therapy on the Plasma Concentrations of Retinol, Alpha-Tocopherol and Coenzyme Q10 in Children with Familial Hypercholesterolemia.

ABSTRACT:

Purpose

Familial hypercholesterolemia (FH) requires early treatment. However, statins, which are regarded the first-line therapy, have an influence on redox balance. Antioxidant vitamins are important for many metabolic processes in the developing body. There are few data available on the long-term safety of statin use in children. The aim of this study was to evaluate the influence of statin treatment in children with FH on plasma concentrations of antioxidant vitamins: retinol, alpha-tocopherol and coenzyme Q10.

Methods

The first study group consisted of 13 children aged 10-18 years treated with simvastatin for at least 6 months, and the second group comprised 13 age- and sex-matched children with hypercholesterolemia, in whom pharmacological treatment had not been applied yet. Analyses were performed using a high-performance liquid chromatograph coupled with a MS detector.

Results

The analysis did not reveal significant differences in the concentration of retinol, alpha-tocopherol or coenzyme Q10 between the studied groups. The adjustment of the concentrations of the vitamins to the cholesterol level also indicated no significant differences. We found no deficits in antioxidant vitamins in patients treated with statins, or any risk of adverse effects associated with an increase in their concentration.

Conclusion

There is no rationale for additional supplementation using antioxidant vitamins or modification of low-fat and low-cholesterol diet in pediatric patients treated with statins.

Project description:BackgroundThe effect of statin treatment on circulating coenzyme Q10 (CoQ10) has been studied in numerous randomized controlled trails (RCTs). However, whether statin treatment decreases circulating CoQ10 is still controversial.MethodsPubMed, EMBASE, and the Cochrane Library were searched to identify RCTs to investigate the effect of statin treatment on circulating CoQ10. We calculated the pooled standard mean difference (SMD) using a fixed effect model or random effect model to assess the effect of statin treatment on circulating CoQ10. The methodological quality of the studies was determined according to the Cochrane Handbook. Publication bias was evaluated by a funnel plot, the Egger regression test, and the Begg-Mazumdar correlation test.ResultsTwelve RCTs with a total of 1776 participants were evaluated. Compared with placebo, statin treatment resulted in a reduction of circulating CoQ10 (SMD, - 2.12; 95% CI, - 3.40 to - 0.84; p = 0.001), which was not associated with the duration of statin treatment (Exp, 1.00; 95% CI, 0.97 to 1.03; p = 0.994). Subgroup analysis demonstrated that both lipophilic statins (SMD, - 1.91; 95% CI, - 3.62 to 0.2; p = 0.017) and hydrophilic statins (SMD, - 2.36; 95% CI, - 4.30 to - 0.42; p = 0.028) decreased circulating CoQ10, and no obvious difference was observed between the two groups (SMD, - 0.20; 95% CI, - 0.208 to 0.618; p = 0.320). In addition, both low-middle intensity statins (SMD, - 2.403; 95% CI, - 3.992 to - 0.813; p < 0.001) and high intensity statins (SMD, - 1.727; 95% CI, - 2.746 to - 0.709; p < 0.001) decreased circulating CoQ10. Meta-regression showed that the effect of statin on decreasing circulating CoQ10 was not closely associated with the duration of statin treatment (Exp, 1.00; 95% CI, 0.97 to 1.03; p = 0.994).ConclusionsStatin treatment decreased circulating CoQ10 but was not associated with the statin solution, intensity, or treatment time. The findings of this study provide a potential mechanism for statin-associated muscle symptoms (SAMS) and suggest that CoQ10 supplementation may be a promising complementary approach for SAMS.
