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.

Nature and Nurture

Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience, such as differences...

Pharmacokinetics in Pediatric Patients: Drug Metabolism

In pediatric care, understanding the nuances of hepatic drug metabolism is crucial, as it significantly differs from that of adults. This divergence is primarily due to the developmental stage of drug-metabolizing enzymes, which affects how medications are processed in the body. In neonates, for instance, the activity of Phase I enzymes—critical for the initial breakdown of drugs—is markedly reduced, functioning at just 20–40% of the levels seen in adults. This reduction poses a challenge in...

Factors Affecting Drug Response: Overview

When it comes to infants and young children, they are typically administered smaller doses of medication in comparison to adults. This is primarily because their organ functions still need to fully develop, meaning their bodies are not as efficient at metabolizing or eliminating drugs. Additionally, their blood-brain barrier is more permeable than in adults. As a result, high concentrations of drugs can easily penetrate the central nervous system (CNS), potentially leading to neurological...
Signs of Puberty01:27

Signs of Puberty

Puberty is a critical phase, typically beginning between the ages of 8 and 13 in girls and 9 and 14 in boys, though timing can vary based on genetics, environmental factors, and overall health. This period is characterized by the development of secondary sexual characteristics and the attainment of reproductive potential. Endocrine changes underpin puberty, with hormonal surges of Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH) instigated by Gonadotropin-Releasing Hormone (GnRH)...
Hypoglycemia and Glucagon01:15

Hypoglycemia and Glucagon

Without prolonged fasting, healthy individuals maintain blood glucose levels above 3.5 mM due to a well-adapted neuroendocrine counterregulatory system that effectively prevents acute hypoglycemia, a potentially life-threatening condition. The primary clinical scenarios for hypoglycemia encompass diabetes treatment, inappropriate production of endogenous insulin or insulin-like substances by tumors, and the use of glucose-lowering agents in non-diabetic individuals. Notably, hypoglycemia in the...

Drug Dosing: Infants and Children

Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...
