Abstract

Although spontaneous remyelination does occur in multiple sclerosis lesions, its extent within the global population with this disease is presently unknown. We have systematically analysed the incidence and distribution of completely remyelinated lesions (so-called shadow plaques) or partially remyelinated lesions (shadow plaque areas) in 51 autopsies of patients with different clinical courses and disease durations. The extent of remyelination was variable between cases. In 20% of the patients, the extent of remyelination was extensive with 60-96% of the global lesion area remyelinated. Extensive remyelination was found not only in patients with relapsing multiple sclerosis, but also in a subset of patients with progressive disease. Older age at death and longer disease duration were associated with significantly more remyelinated lesions or lesion areas. No correlation was found between the extent of remyelination and either gender or age at disease onset. These results suggest that the variable and patient-dependent extent of remyelination must be considered in the design of future clinical trials aimed at promoting CNS repair.

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?

  • On average, in MS, only 20% of patients display efficient (above 60%) remyelination of lesions as shown by histochemistry in shadow plaques.

    “On average, in MS, only 20% of patients display efficient (above 60%) remyelination of lesions as shown by histochemistry in areas of pale myelin stain called “shadow plaques” (16).”
  • The efficacy of remyelination depends on multiple factors such as age, disease duration and lesion location.

    “The efficacy of remyelination has been shown to depend on multiple factors such as, age, disease duration and lesion location.”
  • About 20-30% of examined postmortem MS tissues show signs of remyelination, which can happen at both early and late stages of the disease.

    “About 20–30% of examined postmortem MS tissues show signs of remyelination, which can happen at both early and late stages of the disease [85,86].”
  • Remyelination frequently occurs after demyelinating events but is often incomplete.

    “Although remyelination frequently occurs after demyelinating events, it is often incomplete (Patrikios et al., 2006; Goldschmidt et al., 2009).”

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.
