Insights

Growth hormone treatment (GHt) is safe for adults with Prader-Willi syndrome (PWS), improving body composition. This may help reduce cardiovascular risks in this population.

Area of Science:

  • Endocrinology
  • Genetics
  • Metabolic Disorders

Background:

  • Prader-Willi syndrome (PWS) shares features with growth hormone (GH) deficiency, including short stature and altered body composition.
  • GH treatment (GHt) is standard for PWS children, improving health and cognition, but its role in adults is less established.

Purpose of the Study:

  • To review current knowledge on the efficacy and safety of GH treatment in adults with Prader-Willi syndrome.

Main Methods:

  • A systematic literature search was conducted across Medline, Embase, and Cochrane Central Register.
  • Included studies were randomized clinical trials (RCTs) and nonrandomized controlled trials (NRCTs) of adults with PWS receiving GHt for ≥6 months.
  • Data extracted included body composition, BMI, cardiovascular markers, bone density, cognition, quality of life, and safety.

Main Results:

  • Nine RCTs and 20 NRCTs were analyzed. GHt over 12 months significantly improved body composition, increasing lean body mass and reducing fat mass.
  • No significant changes were observed in BMI, cholesterol, fasting glucose, or bone mineral density.
  • No major safety concerns were reported with GHt in PWS adults.

Conclusions:

  • GH treatment appears safe and beneficial for improving body composition in adults with Prader-Willi syndrome.
  • Enhanced body composition may potentially lower the high incidence of cardiovascular morbidity associated with PWS.
  • Further research may solidify GHt as a therapeutic option for adults with PWS.

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...

Insulin: Dosing Regimen and Adverse Effects01:16

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...

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 Disorders01:27

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...

Major Hormones and Their Functions01:27

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...
