Insights
Growth hormone (GH) therapy effectively improves height in preterm small for gestational age (SGA) children. This treatment promotes growth without accelerating bone age or negatively impacting metabolism.
Area of Science:
- Pediatric Endocrinology
- Growth Hormone Therapy
- Neonatology
Background:
- Small for gestational age (SGA) children often require intervention for growth. Preterm SGA infants face additional risks for short stature.
- Limited data exists on growth hormone (GH) efficacy in preterm SGA populations.
Purpose of the Study:
- To evaluate the efficacy of GH treatment in preterm SGA children.
- To assess growth, metabolic parameters, and bone age progression in treated preterm SGA patients.
Main Methods:
- A cohort of 25 preterm SGA children (2-4 years old) received GH (0.066 mg/kg/day).
- Growth, IGF-I, IGFBP-3, glucose, and insulin levels were monitored for two years.
- Compared with 14 age-matched preterm SGA historical controls.
Main Results:
- GH treatment led to significant height SDS increases of 1.3 and 2.1 in the first and second years, respectively.
- Growth hormone therapy increased IGF-I and IGFBP-3 levels without affecting bone age acceleration.
- No adverse effects on glucose metabolism or insulin resistance were observed.
Conclusions:
- GH treatment demonstrates comparable height gains in preterm SGA children to those seen in term SGA patients.
- Short-term GH therapy is effective for promoting growth recovery in preterm SGA children aged 2-4 years.
- GH therapy is safe regarding bone maturation and carbohydrate metabolism in this cohort.
Background:
Growth hormone (GH) is a therapeutic option for small for gestational age (SGA) children without spontaneous catch-up. There are few reports on preterm SGA children. Prematurity is an additional risk factor for adult short stature.
Aim:
To describe GH efficacy in preterm SGA patients.
Methods:
Twenty-five preterm SGA patients, 2-4 years old, treated with GH 0.066 mg/kg/day, were compared with 14 age-matched preterm SGA historical controls. Height, weight, IGF-I, IGFBP-3, fasting glucose and insulin were measured every 6 months.
Results:
At start of GH treatment, mean height and weight were -2.4 and -2.4 SDS, respectively. There was a significant increment in height SDS of 1.3 and 2.1 during the 1st and the 2nd year of GH therapy, respectively. There was no significant difference between the progression of chronological and bone ages. A significant increase in IGF-I, IGFBP-3 and molar ratio was observed during GH therapy. There was no difference in glucose, insulin or HOMA-IR index.
Conclusion:
We showed for the first time that the height increment of preterm SGA with GH treatment is similar to that described in other studies with term SGA patients. Therefore, short-term GH treatment in a subset of preterm SGA patients between 2-4 years of age was able to promote adequate growth recovery with no excessive bone age acceleration or adverse effects on carbohydrate metabolism.
