Optimizing growth hormone therapy during puberty.
During puberty, growth hormone (GH)-deficient children may experience difficulties achieving an appropriate pubertal growth spurt. We review the complex hormonal interactions which occur during puberty. At least two therapeutic strategies have been developed to optimize GH therapy during puberty. In the first strategy, the GH dose administered per kilogram of body weight is increased during puberty, in an attempt to mimic the physiological increase of GH which occurs during puberty. In the second strategy, luteinizing hormone-releasing hormone (LHRH) analogs are administered concomitantly with GH with the aim of delaying epiphyseal fusion. The efficacy of these strategies to increase final height has not previously been clearly demonstrated.
