Study population: Potential subjects include all those who present to our Neuroendocrine Unit for therapy of GH deficiency or who are followed in our unit and have GH deficiency and are planning to initiate a therapy.

  • Males or females age ≥18 years with diagnosis of GH deficiency that is Adult Onset, either alone or associated with multiple pituitary hormone deficiencies and due to pituitary disease,hypothalamic disease, surgery, radiation therapy or Childhood Onset due to congenital, genetic, acquired, or idiopathic causes.
  • Diagnosis of GH deficiency defined by: insulin tolerance test or glucagon test: peak growth hormone response < 3 ng/ml or 3 or more pituitary hormone deficiencies and IGF-1 standard deviation score < -2.0
  • No history of diabetes mellitus and fasting blood sugar at screening visit ≤ 120 mg/dl.
  • If patients have undergone surgical resection of a pituitary adenoma, a minimum of 12 months must have elapsed post surgery prior to enrollment and tumor will be demonstrated to be unchanged for 12 months or longer since surgery.
  • May have a history of radiotherapy, but they must have completed their course of radiotherapy more than 3 months prior to study screening.
  • If prior GH therapy must have not received prior growth hormone replacement therapy in 310 the 6 months prior to screening.

If of childbearing potential, agrees to use a medically acceptable form of contraception (such as oral, implantable, or barrier contraception) from the time of screening, for the duration of the study, and for at least one month after study discontinuation or completion. Childbearing potential is defined as women who are not surgically sterile or not at least one year postmenopausal.

About this study

Official title: Adipose Tissue and Serum Inflammation in Growth Hormone (GH) Deficiency

This study will examine adipose tissue inflammation and adipokine expression and serum markers of inflammation and adipokine levels in patients with growth hormone (GH) deficiency before and after treatment.

Read the detailed description

The GH axis has important influences on adipose tissue. Preliminary data from the investigators' study in acromegaly, a state of GH excess, suggests that GH reduces adipose tissue (AT) mass and serum inflammation. However, GH seems to reduce macrophage markers in adipose tissue yet increase adipocyte inflammation. This novel dissociation of macrophage and adipocyte inflammation is hypothesized to be due to GH. In order to examine this hypothesis further this study will examine adipose tissue and serum inflammation in patients with GH deficiency before and after GH therapy. The investigators will obtain subcutaneous adipose tissue by biopsy in patients with active GH deficiency planning to undergo therapy for GH deficiency. Concurrently serum samples will be taken for analysis of levels of inflammatory markers and adipokines. After treatment for 12 months with a normal levels of Insulin-like growth factor 1 (IGF-1), a marker of GH deficiency, patients will have a repeat adipose tissue biopsy. Adipose tissue parameters will be analyzed in each specimen and then compared to each patient over time as well as to body mass index (BMI)-matched control subjects.

Questions about this trial

What is this clinical trial studying?

An observational study of Growth Hormone Deficiency, run by Columbia University at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 19 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 13 May 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Visceral Adipose Tissue (VAT) mass (time frame: Baseline to 12 months of GH therapy). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 May 2025.
