Growth hormone treatment of renal growth failure during infancy and early childhood

Insights

Early recombinant human growth hormone (rhGH) therapy can improve final height in infants with chronic kidney disease (CKD). This safe and effective treatment offers benefits including reduced costs and improved psychosocial outcomes.

Area of Science:

  • Pediatric Nephrology
  • Endocrinology
  • Growth Medicine

Background:

  • Growth failure in infants and toddlers with chronic kidney disease (CKD) remains a significant challenge despite advances in treatment.
  • Early growth deficit is a key factor contributing to impaired final height in pediatric CKD patients.

Discussion:

  • Recombinant human growth hormone (rhGH) therapy is proposed as an early intervention for infants experiencing growth failure.
  • Candidates for rhGH therapy include infants with delayed growth, sufficient caloric intake, and stable bone metabolism.
  • Growth retardation at birth may serve as a predictive factor for rhGH treatment selection.

Key Insights:

  • Limited data suggest rhGH is effective and safe for young children with CKD.
  • Early rhGH use requires lower dosages, reducing treatment costs and facilitating earlier renal transplantation.
  • Initiating rhGH therapy early improves psychosocial well-being and potentially final adult height.

Outlook:

  • A multi-center randomized controlled study is needed to evaluate the short- and long-term effects of early rhGH therapy in infants with CKD.

Hormones and Bone Tissue01:17

Hormones and Bone Tissue

The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...

Pharmacokinetics in Pediatric Patients: Drug Excretion

In pediatric medicine, understanding the renal function and drug elimination nuances is crucial for administering safe and effective treatments. Newborns, in particular, display markedly slower renal functions than adults, profoundly affecting how drugs are cleared from their bodies. This slower drug clearance requires clinicians to extend the dosing intervals for many medications to prevent drug accumulation and toxicity while ensuring therapeutic efficacy.One key area where these adjustments...
Nature and Nurture01:10

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...

Insulin: Dosing Regimen and Adverse Effects

Insulin-replacement therapy usually includes both long-acting insulin (basal) and short-acting insulin (to cater to postprandial needs). In a diverse group of type 1 diabetes patients, the average daily insulin dose is typically 0.5-0.7 units/kg body weight. However, obese patients and pubertal adolescents may need more due to insulin resistance.
The basal dose constitutes about 40%-50% of the total daily dose, with the rest as premeal insulin. The mealtime insulin dose should mirror...
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...
