Zusammenfassung
Neugeborene mit einer sehr niedrigen Geburtslänge oder einem sehr niedrigen Geburtsgewicht, die mehr als 2 Standardabweichungen unterhalb des Durchschnitts eines Vergleichskollektivs gleichen Gestationsalters liegen, sind definitionsgemäß „small for gestational age“ (SGA). Die Ursachen für die zu niedrigen Geburtsmaße sind vielfältig. Bei 90% der Betroffenen normalisieren sich Körpergröße bzw. -länge bis zum Alter von etwa 3 Jahren, 10% bleiben dauerhaft klein (SGA-Kleinwuchs). Das spontane Aufholwachstum nach der Geburt sollte in Relation zur elterlichen Zielgröße beurteilt werden – auch im Hinblick auf die Indikation zur Therapie mit Wachstumshormon (WH). Diese ist in Deutschland seit 2003 zur Förderung des Längenwachstums bei Kindern mit ausgeprägtem SGA-Kleinwuchs und unzureichendem Aufholwachstum zugelassen. Sie sollte frühzeitig, in jedem Fall ausreichend lange vor der Pubertät eingeleitet werden. Kinder, die nicht oder schlecht auf eine WH-Therapie ansprechen, sind meist schon im ersten Behandlungsjahr zu erkennen, die WH-Therapie sollte in diesen Fällen abgebrochen werden.
Abstract
Neonates of short birth length or low birth weight demonstrating more than 2 standard deviations below the average of a comparison group for the same gestational age are referred to as small for gestational age (SGA). The causes of low birth measurements are multifaceted. In 90% of infants affected body length normalizes by 3 years of age, while 10% remain permanently short (SGA short stature). Spontaneous catch-up growth following birth should be evaluated in relation to the parental target height. This also applies to the indication for growth hormone (GH) therapy, which has been approved for use in Germany since 2003 to promote growth in children with pronounced SGA short stature and insufficient catch-up growth. This therapy should be initiated promptly and always at a sufficient interval prior to puberty. Children failing to respond to GH therapy, or responding only poorly, can usually be indentified in the first year of therapy, at which point therapy should be discontinued.
