Abstract

irst described by Smith et al 1 in 1982, Smith-Magenis syndrome (SMS) is a contiguous gene syndrome ascribed to interstitial deletions of chromosome 17p11.2.Clinical features include infantile hypotonia, characteristic craniofacial appearance, brachydactyly, short stature, ocular anomalies, deep, hoarse voice, early speech delay, mental retardation, and behavioural disturbances.2 3 Behavioural problems include hyperactivity, attention deficit, self-injury, temper tantrums, and major sleep disturbance.4 These symptoms have a major impact on the children and their families.The diagnosis is based on high resolution karyotype analysis and fluorescence in situ hybridisation (FISH).5 Sleep disturbances occur in all cases and are predictive of maladaptive behaviour, increased by mental retardation and cognitive delay.The specific pattern of sleep disturbance in SMS includes early sleep onset, frequent awakenings, and early waking.6 7 Moreover, "sleep attacks" at the end of the day are consistent features of the disease and may represent the endogenous sleep onset of the patients.The children could therefore be regarded as having a sleep phase advance.Normally, melatonin secretion increases soon after onset of darkness, peaks at midnight, and gradually falls during the second half of the night.Interestingly, all SMS patients display a phase shift of their circadian rhythm of melatonin, with a diurnal secretion of the hormone 8-10 (fig 1).Tantrums and tiredness occur when melatonin rises in the morning and children have naps and sleep attacks when melatonin peaks at midday and in the evening.Sleep is fragmented with prolonged nocturnal awakenings and early waking when melatonin is low during the night (fig 1).This clinical and biological sleep phase advance supports the existence of an aberrant biological clock in SMS.Because the circadian rhythm of melatonin is controlled by the sympathetic nervous system, 11 12 SMS children were given acebutolol, as β 1 -adrenergic antagonists reduce the production of melatonin.13 14 Here, we show that the combination of morning β 1 -adrenergic antagonist and evening melatonin administration restored plasma circadian melatonin rhythm, decreased the frequency of behavioural disturbances, and enhanced sleep in SMS. METHODS PatientsTen children (six boys, four girls, aged 4-18 years) were recruited from the cohort of SMS children diagnosed at Necker-Enfants Malades Hospital, Paris.The bioethical human research committee approved the investigation protocol and the parents signed an informed consent form before inclusion in the study.All SMS patients met the inclusion clinical criteria, namely: facial dysmorphism, developmental delay, speech delay, hyperactivity, attention deficit, and sleep disturbances.All carried a 17p11-2 deletion confirmed by

  • Combining β1-adrenergic receptor antagonism with timed administration of exogenous melatonin greatly improves sleep and also reduces disruptive behaviours during the daytime in children and adolescents with SMS.

    “Combining β1-adrenergic receptor antagonism with timed administration of exogenous melatonin greatly improves sleep (that is, leading to fewer sleep awakenings and better organized sleep stages) and also reduces disruptive behaviours during the daytime in children and adolescents with SMS137.”
  • Therapies targeting the reversal of melatonin rhythms in patients with SMS may improve sleep, as well as behaviour, attention and learning.

    “Thus, therapies targeting the reversal of melatonin rhythms in patients with SMS may improve sleep, as well as behaviour, attention and learning137–139.”

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.
