Presentation
At present, patients suffering from IGHD-2 are treated with daily injections of recombinant human GH (rhGH) in order to reach normal height. [ncbi.nlm.nih.gov]
However, some cases present with anterior hypoplasia, and it is not ruled out that pituitary image findings may evolve with time. [edmcasereports.com]
Additionally, patients with GHD from organic causes such as tumors and radiation, in which no gender bias should be present, were still 62% male. [rarediseases.org]
Because the structure of the infant’s larynx, high-pitched voice in present also in adults. [doctortipster.com]
Approximately 50% of males present in the first few months of life, whereas the remaining boys present more insidiously later in childhood. [clinicaladvisor.com]

In infancy, he was of proportionate short stature with certain phenotypic features such as puppet-face appearance. We are not aware of hypoglycemic episodes or micropenis in childhood and he had no problems related to dentition or puberty. [edmcasereports.com]
Treatment
This chapter focuses on molecular strategies that could represent future directions for IGHD-2 treatment. Copyright © 2012 S. Karger AG, Basel. [ncbi.nlm.nih.gov]
Treatment is expensive, costing as much as US $10,000 to $40,000 a year in the USA. [en.wikipedia.org]

In some children, GH can lead to four inches (10 centimeters) of growth during the first year of treatment. Others grow less, but usually faster than without treatment. Some children need treatment until adolescence; others need it into adulthood. [hormone.org]
After 1 month of treatment, there was no increase in IGF1 or IGFBP3 levels. [edmcasereports.com]
Prognosis
Outlook for Growth Hormone Deficiency The prognosis is determined by the patient’s response to growth hormone replacement therapy and the underlying cause of the deficiency. Muscle mass may increase. The patient may lose weight. [emedicinehealth.com]
Long-term Follow-up and Prognosis Patients treated for acromegaly need to be monitored to make sure that GH excess does not return. [londonendocrinecentre.co.uk]
In contrast to acquired hypopituitarism cases, congenital severe GHD cases have much lower serum IGF1 levels and have never been exposed to GH and thus they may not be equivalent in terms of GH/IGF1 axis disturbances and health prognosis. [edmcasereports.com]

Etiology
Abstract Isolated growth hormone deficiency (IGHD) is the commonest pituitary hormone deficiency resulting from congenital or acquired causes, although for most patients its etiology remains unknown. [ncbi.nlm.nih.gov]
Of more than 20,000 children receiving growth hormone in the National Cooperative Growth Study (a database of patients receiving growth hormone therapy), approximately 25% of the patients with growth hormone deficiency had an organic etiology. [emedicine.medscape.com]

Second, epidemiological studies have shown a relationship between tall statue and cancer risk, between insulinlike growth factor I (IGF-I) levels and the risk of prostate cancer, and an increase in breast cancer associated with levels of free IGF-I. [emedicine.medscape.com]
However, it may be that those adults with poor QoL at the start of treatment do benefit. [7] Epidemiology [ edit ] The incidence of idiopathic GHD in infants is about 1 in every 3800 live births, [16] and rates in older children are rising as more children [en.wikipedia.org]

The pathophysiology for this positive results appears to be the natural mediatory and regulatory effects of rhGH on the neurotransmitters of the central nervous system (CNS), which seem to perform better than psychotropic drugs. [hgfound.org]

Pathophysiology [ edit ] As an adult ages, it is normal for the pituitary to produce diminishing amounts of GH and many other hormones, particularly the sex steroids. [en.wikipedia.org]
Prevention
However, this type of replacement therapy, although effective in terms of growth, does not prevent toxic effects of the 17.5-kD mutant on the pituitary gland, which can eventually lead to other hormonal deficiencies. [ncbi.nlm.nih.gov]
Mutations in the GH1 gene prevent or impair the production of growth hormone. [ghr.nlm.nih.gov]
