Abstract

The most common and problematic side effect of statins is myopathy. To date, the patho-physiological mechanisms of statin myotoxicity are still not clearly understood. In previous studies, we showed that acute application in vitro of simvastatin caused impairment of mitochondrial function and dysfunction of calcium homeostasis in human and rat healthy muscle samples. We thus evaluated in the present study, mitochondrial function and calcium signaling in muscles of patients treated with statins, who present or not muscle symptoms, by oxygraphy and recording of calcium sparks, respectively. Patients treated with statins showed impairment of mitochondrial respiration that involved mainly the complex I of the respiratory chain and altered frequency and amplitude of calcium sparks. The muscle problems observed in statin-treated patients appear thus to be related to impairment of mitochondrial function and muscle calcium homeostasis, confirming the results we previously reported in vitro.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • A prior study's groups were not matched for VO2max, which is problematic because exercise training strongly stimulates mitochondrial biogenesis and unmeasured mitochondrial content differences would affect respiration results.

    “However, the study groups were not matched for maximal oxygen uptake (physical fitness), which is problematic because exercise training is the most powerful stimulus for mitochondrial biogenesis (18), and differences in mitochondrial content (which was not measured in the study [17]) would have had a major influence on the respiratory results.”

  • A prior study of patients on different statins reported lower complex I OXPHOS capacity and no difference in complex II-linked OXPHOS capacity.

    “Recently, the same group investigated mitochondrial function in patients treated with different statins (lipophilic and hydrophilic) and reported the same results: decreased complex I OXPHOS capacity in the patients and no differences in complex II-linked OXPHOS capacity (17).”

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.
