Overview

If left untreated, patients with growth hormone deficiency may progress to develop delayed postnatal growth, delayed bone age, delayed puberty, infantile fat distribution, and infantile voice. Common complications of growth hormone deficiency include osteopenia, dyslipidemia, delayed puberty, and higher mortality rates than normal subjects. Prognosis is generally good with treatment. GH treatment can improve GH-deficient adults symptoms. Since recombinant DNA–derived growth hormone became available, most children with growth hormone deficiency reach normal adult stature.

Natural History, Complications, and Prognosis

Natural History

  • The symptoms of growth hormone deficiency usually develop in the first days of life and start with symptoms such as perinatal asphyxia, neonatal hypoglycemia, reduced birth length, and prolonged jaundice especially if associated with ACTH deficiency. If left untreated, patients with growth hormone deficiency may progress to develop delayed postnatal growth, delayed bone age, delayed puberty, infantile fat distribution, and infantile voice.

Complications

  • Increased risk of recurrent illnesses when compared to their counterparts
  • Fractures of the lumbar spine are somewhat lower in patients with adult-onset GH deficiency[1]
  • The degree of osteopenia appears to correlate directly with the degree of GH deficiency[2]
  • Mortality
    • Patients with growth hormone deficiency have a mortality rate twice that of normal subjects, a difference due to an increased number of cardiovascular events.[6]

Prognosis

  • Recombinant DNA–derived growth hormone has significantly improved the prognosis of growth hormone deficiency.[7]
  • If initiated early, children with growth hormone deficiency tend to achieve normal height potential.

Childhood

  • In the first year of treatment, the growth rate may increase from half as fast as other children are growing to twice as fast.
  • Growth typically slows in the following years but remains above normal.
  • As a result, the treated child may grow into the normal height range. Excess adipose tissue may be reduced.
  • The SOCS2 polymorphism is a genetic marker that could identify among GH-treated patients who are predisposed to have less favorable outcomes.[8]
