Disruption of the Diurnal Rhythm of Plasma Melatonin in Cirrhosis
Abstract
OBJECTIVES: To assess 24-hour plasma melatonin profile as a marker of output rhythm from the circadian clock and to study sleep diaries as reflections of subjective sleep quality in patients with liver cirrhosis. DESIGN: Prospective cohort study. SETTING: Clinical research center in a university hospital. PATIENTS: Seven patients with cirrhosis but not alcoholism and seven age-, sex-, and education-matched controls. MEASUREMENTS: Neuropsychological testing to confirm subclinical hepatic encephalopathy. Plasma melatonin levels measured every 30 minutes for 24 hours by radioimmunoassay. Sleep diaries kept for 1 week before admission. RESULTS: Patients with cirrhosis had markedly elevated melatonin levels during daytime hours; in addition, the time of onset of melatonin increase and the time at which melatonin levels peaked were consistently and significantly delayed in these patients. Sleep diaries indicated more nocturnal awakenings and more frequent daytime naps in patients with cirrhosis. CONCLUSION: Disruption of the diurnal rhythm of melatonin may reflect alterations of circadian function that could contribute to the disturbances of the sleep-wake cycle frequently seen in patients with cirrhosis.

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.
