Insights

Growth hormone replacement therapy (GHRT) is crucial for children with craniopharyngioma (cCP) to improve growth and overall health. Evidence indicates GHRT is safe, with no increased risk of tumor progression in these patients.

Area of Science:

  • Pediatric Endocrinology
  • Neuro-oncology
  • Endocrinology

Background:

  • Childhood onset craniopharyngioma (cCP) frequently leads to growth hormone (GH) deficiency due to the tumor or its treatment.
  • Growth hormone replacement therapy (GHRT) is vital for optimizing growth velocity and final height in affected children.
  • Continuing GHRT into adulthood offers significant benefits for metabolic, bone, mental health, and quality of life.

Purpose of the Study:

  • To review the current evidence on the safety and efficacy of GH replacement therapy (GHRT) in children with craniopharyngioma (cCP).
  • To assess the impact of GHRT on tumor progression, recurrence, secondary neoplasms, and mortality in cCP patients.
  • To provide guidance on the optimal timing for initiating GHRT in newly diagnosed cCP patients.

Main Methods:

  • Systematic review of existing literature and clinical evidence regarding GHRT in cCP.
  • Analysis of studies examining long-term outcomes, including tumor behavior and patient survival.
  • Evaluation of data on the benefits of GHRT for growth and metabolic parameters.

Main Results:

  • Current evidence suggests GHRT does not increase the risk of tumor progression, recurrence, secondary cancers, or mortality in cCP patients.
  • Early initiation of GHRT (as early as three months post-surgery) can effectively address linear growth deficits and metabolic issues.
  • GHRT demonstrates positive effects on bone health, mental well-being, and overall quality of life in cCP survivors.

Conclusions:

  • GH replacement therapy is a safe and beneficial treatment for children with craniopharyngioma experiencing GH deficiency.
  • GHRT should be considered for early initiation to manage growth and metabolic disturbances, with potential for long-term continuation.
  • Further research is warranted on the long-term effects of early GHRT initiation and the use of long-acting GH preparations in cCP patients.

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...

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...

Major Hormones and Their Functions

Hormones, the biochemical messengers produced by endocrine glands, are pivotal in regulating bodily functions and maintaining homeostasis. Each hormone's balance is crucial; imbalances can lead to significant physiological disruptions. Major hormones include oxytocin, cortisol, epinephrine, estrogen, testosterone, thyroxine, growth hormone, insulin, and glucagon.
Oxytocin, produced in the hypothalamus and released by the pituitary gland, plays a role in social bonding, childbirth, and...

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,...

Adrenal Gland Disorders

Adrenal gland disorders manifest when the production of adrenal hormones deviates from the norm, resulting in either excessive or insufficient concentrations.
Adrenal insufficiency, characterized by insufficient cortisol and aldosterone production, leads to conditions like Addison's disease. This disorder, affecting the adrenal cortex, exhibits symptoms such as skin bronzing, dehydration, low blood pressure, fatigue, and weight loss. Congenital adrenal hyperplasia, a genetic ailment causing...

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...
