Childhood short stature in Silver-Russell syndrome (SRS) is frequently treated with growth hormone (GH), however final height and long-term body mass index (BMI) data are limited.
Objective: To assess height and BMI in older individuals with molecularly confirmed SRS and compare those previously treated with GH to those untreated.
Methods: Growth data on individuals aged ≥13 years with SRS were evaluated from UK, French and German cohorts. Height and BMI standard deviation scores (SDS) were calculated using country-specific reference data.
Results: 71 individuals (40 females) aged 13.1769.71 years (median 22.03) were recruited. Molecular diagnoses: loss of methylation at H19/IGF2 (80.3%), maternal uniparental disomy for chromosome 7 (16.9%), IGF2 mutation (2.8%). 77.5% received GH for a median of 7.10 years (IQR 3.96 to 11.00). The median time since GH cessation was 9.97 years (IQR 2.6815.94). Median early height SDS in GH-untreated and GH-treated individuals were −2.91 (IQR −3.62 to −2.40) and −3.46 (IQR −5.15 to −2.76) respectively (P=0.055). Median height gain from early to final height SDS in GH-untreated and GH-treated individuals were 0.53 (IQR −0.13 to 1.37) and 1.53 (IQR 0.80 to 2.52) respectively (P=0.006). The median final height SDS of GH-untreated and GH-treated individuals were −2.74 (IQR −3.36 to −1.13) and −2.22 (IQR −3.66 to −1.16) respectively (P=0.720). Median change in BMI from early to final BMI SDS in GH-untreated and GH-treated individuals were 3.58 (IQR 1.85 to 5.18) and 1.95 (IQR 0.76 to 2.69) respectively (P=0.005). The median BMI SDS of GH-untreated versus GH-treated individuals were 1.66 (IQR −0.73 to 2.03) and −1.10 (IQR −1.80 to 0.00) respectively (P=0.002).
Conclusions: Height gain was significantly greater in GH-treated individuals who (were shorter at treatment initiation but) reached similar final heights to GH-untreated individuals. Historical GH treatment was associated with reduced BMI and reduced gain in BMI, indicating long-term effects.
