Abstract

Aim: Myokines are peptides released by the skeletal muscle, and have gained popularity as potential biomarkers for sarcopenia. Irisin is a recently identified myokine, but its role in pathological sarcopenia remains unclear. We investigated the validity and accuracy of circulating irisin levels as a potential biomarker for sarcopenia. Methods: We evaluated the anthropometrics, body composition, sarcopenia‐related parameters and serum irisin levels of 715 community‐dwelling Koreans. Sarcopenia was determined on the basis of the clinical diagnostic criteria of muscle atrophy and weakness, which were proposed by the Asian Working Group for Sarcopenia. Results: Circulating irisin levels were correlated with appendicular lean mass/height 2 (rmen = 0.275; rwomen = 0.321) and handgrip strength (rmen = 0.219; rwomen = 0.312) in both sexes (all P < 0.01). Furthermore, the mean circulating irisin levels were lower in the sarcopenia group than in the normal group (all P < 0.05). In the logistic regression models, the association between serum irisin concentration and incident sarcopenia persisted even after adjusting for potential confounders, such as sex, age and fat indices (odds ratio 0.20, 95% CI 0.07–0.60; P for trend <0.01). The predictive values of serum irisin for sarcopenia were <1.0 μg/mL in men and <1.16 μg/mL in women, with the area under the receiver operating characteristic curves of 0.87 (95% CI 0.77–0.99) and 0.68 (95% CI 0.55–0.81), respectively (all P < 0.01). Conclusions: A low level of circulating irisin is a sensitive marker for muscle weakness and atrophy. Irisin is a potential biomarker for muscle dysfunction that could help predict the onset of sarcopenia and provide new avenues for monitoring age‐related muscle changes.

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

  • The content of myostatin is upregulated while irisin is downregulated in sarcopenia.

    “However, several studies have documented that the content of myostatin is upregulated while irisin is downregulated in sarcopenia (44).”
  • Myostatin is upregulated in sarcopenia, while irisin appears downregulated.

    “Production of myostatin, a growth-inhibiting myokine, is upregulated in sarcopenia64, whereas that of muscle-mass-stimulating irisin seems to be downregulated65.”

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.
