BACKGROUND: The effectiveness of growth hormone (GH) treatment for height gain in short-stature children born small for gestational age (SGA) with extremely low birthweight (ELBW; birthweight <1,000 g) remains largely unknown.
METHODS: In study 1, 35 prepubertal Japanese children born SGA with ELBW were categorized into three groups based on the presence or absence of catch-up growth by age 3 (CU(+) and CU(-), respectively) and GH treatment (GH(+) and GH(-), respectively). Height standard deviation (SD) scores (HT-SDS) in the CU-/GH+ group (n = 19) were compared with those in the age-matched CU+/GH- (n = 9) and CU-/GH- groups (n = 7). In study 2, 66 prepubertal Japanese SGA children treated with GH were divided into three groups by birthweight: <1,000 g (n = 19), 1,000-2,000 g (n = 20), and >2,000 g (n = 27). Changes in HT-SDS during the initial 3 years of GH treatment were compared among the three groups.
RESULTS: In study 1, the mean HT-SDS in the CU-/GH+ group (-1.15 SD) was similar to that in the CU+/GH- group (-1.39 SD) but higher than that in the CU-/GH- group (-2.24 SD). In study 2, GH achieved a height gain of +1.62 SD in the ELBW group, which was similar to that in the other groups (1,000-2,000 g: +1.46 SD, >2,000 g: +1.53 SD).
CONCLUSIONS: Growth hormone treatment in short-stature children born SGA with ELBW increased HT-SDS, which was similar to that in SGA children born with a birthweight ≥1,000 g. These results indicate that GH treatment may be an effective approach to promote adequate growth recovery for short-stature children born SGA with ELBW.
