Question:
Male, 4 years old, unknown subtype
What if the growth hormone levels are high? Does my son still need to be on growth hormone?
Nurse Lynn’s Response:
Growth hormone therapy is a cornerstone of treatment for individuals with PWS. It helps promote growth, improve body composition, enhance muscle tone, and support overall metabolic and cognitive functions, and other challenges common in PWS.
If your son’s IGF-1 levels are elevated, it doesn’t necessarily mean GH therapy should be stopped. Elevated IGF-1 levels often indicate that the GH dose may be too high, potentially increasing the risk of side effects like glucose intolerance, joint problems, or worsening sleep apnea. However, rather than discontinuing therapy, the endocrinologist will likely adjust the dosage to find the optimal balance.
Monitoring of IGF-1 levels, growth velocity, and body composition is crucial, as these measurements help tailor GH therapy to suit your son’s specific needs. The endocrinologist may also consider family height patterns and other individual factors to ensure that the therapy is effective and safe.
Regular follow-up assessments will guide adjustments to the GH dose, ensuring that your son continues to benefit from the therapy without risking side effects.
Additionally, I recommend reaching out to the International Prader-Willi Syndrome Organization (IPWSO). They offer an ‘Ask a Professional’ service, where your questions are reviewed by experts, including members of their Clinical and Scientific Board. They often have local contacts and can assist with both medical inquiries and advocacy for your child: Ask a Professional – IPWSO
