Insights

Cyproheptadine therapy significantly improved growth and insulin-like growth factor-I (IGF-I) levels in underweight children. This appetite stimulant enhanced both weight and height velocity, offering a potential therapeutic benefit.

Area of Science:

  • Pediatrics
  • Endocrinology
  • Nutrition

Background:

  • Cyproheptadine is an appetite stimulant used for underweight children, with known growth-promoting effects.
  • Concerns exist regarding its potential to inhibit growth hormone (GH) secretion.
  • The impact of cyproheptadine on insulin-like growth factor-I (IGF-I), a key mediator of GH action, remains undocumented.

Purpose of the Study:

  • To investigate the effects of cyproheptadine on growth parameters and serum IGF-I concentrations in underweight children.
  • To assess whether cyproheptadine influences IGF-I levels, a critical factor in growth.
  • To evaluate the overall impact of cyproheptadine on the growth velocity of children with poor appetite.

Main Methods:

  • A randomized controlled trial involving 21 underweight children.
  • Participants were assigned to either a cyproheptadine group (n=10) or a placebo group (n=11).
  • Treatment duration was 4 months, with serum IGF-I levels measured for comparison.

Main Results:

  • Children receiving cyproheptadine demonstrated significantly greater weight and height velocities compared to the placebo group.
  • Serum IGF-I z-scores were notably higher in the cyproheptadine intervention group.
  • These findings indicate a positive effect of cyproheptadine on growth markers.

Conclusions:

  • Cyproheptadine therapy effectively increases caloric intake and serum IGF-I concentration in underweight children.
  • The observed increase in IGF-I correlates with enhanced growth velocity.
  • Cyproheptadine shows promise as a therapeutic agent for improving growth in underweight pediatric populations.

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...
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...

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...

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...

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...

Pharmacokinetics in Pediatric Patients: Drug Distribution

Drug distribution in the pediatric population exhibits unique challenges and considerations due to the physiological differences between children, particularly neonates and infants, and adults. A crucial aspect of pediatric pharmacology is understanding how these differences impact the pharmacokinetics of various drugs, necessitating age-specific dosing strategies to ensure efficacy and safety.Neonates and infants have a higher total body water content, ~75%–90% of their body weight, compared...
