Sleep enhances nocturnal plasma ghrelin levels in healthy subjects

Abstract

Ghrelin, an endogenous ligand of the growth hormone secretagogue receptor, has been shown to promote slow-wave sleep (SWS, non-REM sleep stages 3 and 4). Plasma levels of ghrelin are dependent on food intake and increase in sleeping subjects during the early part of the night. It is unknown whether sleep itself affects ghrelin levels or whether circadian networks are involved. Therefore, we studied the effect of sleep deprivation on nocturnal ghrelin secretion. In healthy male volunteers, plasma levels of ghrelin, cortisol, and human growth hormone (hGH) were measured during two experimental sessions of 24 h each: once when the subjects were allowed to sleep between 2300 and 0700 and once when they were kept awake throughout the night. During sleep, ghrelin levels increased during the early part of the night and decreased in the morning. This nocturnal increase was blunted during sleep deprivation, and ghrelin levels increased only slightly until the early morning. Ghrelin secretion during the first hours of sleep correlated positively with peak hGH concentrations. We conclude that the nocturnal increase in ghrelin levels is more likely to be caused by sleep-associated processes than by circadian influences. During the first hours of sleep, ghrelin might promote sleep-associated hGH secretion and contribute to the promotion of SWS.

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

  • The nocturnal ghrelin elevation is dampened when subjects are sleep deprived.

    “the nocturnal ghrelin elevation is dampened when subjects are sleep deprived [43].”
  • The relationship between sleep and metabolism has been extensively studied in human subjects under varying conditions, such as total sleep deprivation, partial sleep deprivation, and sleep fragmentation.

    “The relationship between sleep and metabolism has been extensively studied in human subjects under varying conditions, such as total sleep deprivation,87–100 partial sleep deprivation,101–122 and sleep fragmentation123–125 (Table 1).”
  • One night of total sleep deprivation markedly decreases the GH peak around sleep onset.

    “One night of total sleep deprivation markedly decreased the GH peak that usually occurs around sleep onset45,95”
  • Mean 24-hour plasma cortisol often remains unchanged by sleep deprivation, but circadian cortisol pattern changes.

    “Mean 24-h levels of plasma cortisol often remain unchanged by sleep deprivation,43,95,96,99,106,109,123 but the circadian cortisol-pattern changes, as described above.”
  • Partial and total sleep deprivation cause delay and/or reduction in cortisol acrophase.

    “In addition, a delay and/or a reduction in the acrophase of cortisol have been reported after partial and total sleep deprivation.95,102,109”

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.
