European Child & Adolescent Psychiatry Aims and scope Submit manuscript

Abstract

Concentrations of melatonin in overnight and first-voiding urine samples from 10 people with autism, 15 parents, 1 grandparent, 9 sibs without autism, and 10 healthy, unrelated volunteers, were measured by radioimmunoassay. Those with autism had significantly higher melatonin concentrations in the first voiding samples than controls. Groups did not differ in overnight melatonin concentrations. These preliminary results warrant replication and extension.

Résumé

Les concentrations de métalonine sur l'ensemble de la nuit et la première émission d'urine provenant d'échantillon de 10 sujets atteints d'autisme, 15 parents, 1 grandparent, 9 membres de la fratrie sans autisme et 10 volontaires sains sans relation avec les patients, furent mesurés par une technique de radio immuno-essai. Les patients avec autisme ont des concentrations de mélatonine significativement plus élevées dans les échantillons de première émission que les contrôles. Les

Zusammenfassung

Die Urinkonzentrationen von Melatonin wurden von 10 Personen mit Autismus, 15 Elternteilen, einem Großelternteil, 9 Geschwistern ohne Autismus und 10 gesunden, nicht verwandten freiwilligen Kontrollpersonen im Radioimmunoassay bestimmt. Die Urinproben wurden über Nacht und bei erster Blasenentleerung gewonnen.

Personen mit Autismus hatten signifikant höhere Melatoninkonzentrationen in den Urinproben, die nach erster Blasenentleerung gewonnen wurden. Die Gruppen unterschieden sich nicht im Hinblick auf die Konzentrationen in den Urinproben, die bei Nacht gewonnen worden waren. Diese vorläufigen Ergebnisse sollten repliziert und ausgedehnt werden.
