Insights

Adherence to growth hormone (GH) therapy is crucial for children. Factors like therapy duration and device choice impact adherence, affecting treatment outcomes and height velocity.

Area of Science:

  • Pediatric Endocrinology
  • Pharmacotherapy Adherence
  • Growth Disorders

Background:

  • Growth hormone (GH) therapy is vital for children with growth deficiencies.
  • Objective assessment of treatment adherence is essential for optimizing outcomes.
  • Understanding factors influencing adherence can improve patient management.

Purpose of the Study:

  • To objectively assess adherence to GH therapy in pediatric patients.
  • To identify factors associated with poor adherence.
  • To determine the impact of adherence on treatment efficacy, specifically height velocity.

Main Methods:

  • Retrospective analysis of 75 children undergoing GH therapy over 12 months.
  • Utilized general practitioner (GP) prescription data to objectively measure adherence.
  • Statistical analysis to correlate adherence with therapy duration, device choice, prescription length, and height velocity.

Main Results:

  • 23% of children missed more than two weekly injections.
  • Lower adherence was significantly associated with longer GH therapy duration (p<0.005).
  • Lack of choice in delivery devices (p<0.005) and short prescription durations (p<0.005) also correlated with lower adherence.
  • Lower adherence predicted reduced height velocities (p<0.05).

Conclusions:

  • Objective assessment reveals significant adherence challenges in pediatric GH therapy.
  • Therapy duration, delivery device options, and prescription length are key factors influencing adherence.
  • Improved adherence strategies are needed to optimize growth outcomes in children receiving GH therapy.

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...

Therapeutic Drug Monitoring: Affecting Factors

Therapeutic Drug Monitoring (TDM) is the clinical practice of measuring specific drug levels in a patient's blood or body tissues to manage and optimize therapy. TDM is crucial for drugs with narrow therapeutic windows, like warfarin and phenytoin, where incorrect doses can lead to treatment failure or severe side effects. This monitoring ensures the dosage administered is within a safe and effective range. The factors affecting therapeutic drug monitoring include:Patient-Specific Factors:a.

Therapeutic Drug Monitoring: Overview and Classification

Therapeutic Drug Monitoring (TDM) is a clinical practice that measures specific drug levels in a patient's blood at designated intervals to ensure the drug concentration stays within a therapeutic range. This monitoring is crucial for optimizing individual dosage regimens, enhancing therapeutic efficacy, and minimizing drug-related toxicity. TDM is vital for drugs with narrow therapeutic windows, significant variability in pharmacokinetics, and a clear correlation between plasma levels and...
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...

Therapeutic Drug Monitoring: Drug Analysis Methods

Therapeutic Drug Monitoring (TDM) is a clinical practice that measures specific drug levels in a patient's blood or body tissues to tailor drug therapy effectively. This monitoring is critical for managing drugs with narrow therapeutic indices like digoxin and phenytoin, ensuring they are both safe and effective. For instance, monitoring theophylline levels in asthma patients involves precision and sensitivity to adjust doses according to individual responses to therapy, ensuring efficacy and...
