Abstract

1 Statins inhibit synthesis of mevalonate, a precursor of ubiquinone that is a central compound of the mitochondrial respiratory chain. The main adverse effect of statins is a toxic myopathy possibly related to mitochondrial dysfunction. 2 This study was designed to evaluate the effect of lipid‐lowering drugs on ubiquinone (coenzyme Q10) serum level and on mitochondrial function assessed by blood lactate/pyruvate ratio. 3 Eighty hypercholesterolaemic patients (40 treated by statins, 20 treated by fibrates, and 20 untreated patients, all 80 having total cholesterol levels >6.0 mmol l−1) and 20 healthy controls were included. Ubiquinone serum level and blood lactate/pyruvate ratio used as a test for mitochondrial dysfunction were evaluated in all subjects. 4 Lactate/pyruvate ratios were significantly higher in patients treated by statins than in untreated hypercholesterolaemic patients or in healthy controls (P<0.05 and P<0.001). The difference was not significant between fibrate‐treated patients and untreated patients. 5 Ubiquinone serum levels were lower in statin‐treated patients (0.75 mg l−1±0.04) than in untreated hypercholesterolaemic patients (0.95 mg l−1±0.09; P<0.05). 6 We conclude that statin therapy can be associated with high blood lactate/pyruvate ratio suggestive of mitochondrial dysfunction. It is uncertain to what extent low serum levels of ubiquinone could explain the mitochondrial dysfunction.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
