Longer-Term Study Confirms Benefit With Growth Hormone in Prader-Willi Syndrome
Short-term data suggest a positive effect of growth hormone (GH) on mental and motor development in infants and children with Prader-Willi syndrome (PWS). Recently, a Dutch study confirmed these benefits in a prospective, cohort study examining 3 years of GH treatment.
During the 3-year treatment period, mental and motor developmental were assessed using Bayleys Scales of Infant Development II (BSID-II) and expressed as % of the expected development (100%). The investigators found that mental development increased from 58.1% at baseline to 79.6% and that motor development increased from 41.9% to 78.2% (both P<.01). Lower baseline psychomotor development and younger age at start of GH treatment were associated with a higher increase in mental and motor development (P<.01).
The investigators concluded that GH treatment, particularly when started as young as possible, helped reduce the gap between infants with PWS and their non-PWS, healthy counterparts.
