About this study

Official title: Diagnosis of Adult Growth Hormone Deficiency With Growth Hormone Releasing Hormone Plus Arginine Stimulation Test

The purpose of this study was to validate the growth hormone releasing hormone (GHRH) plus arginine (GHRH+arg) stimulation test and it´s cut-off limits for diagnosis of adult growth hormone deficiency using the growth hormone (GH) Immulite 2000 Xpi assay calibrated against the IS 98/574 from the World Health Organization. A specific aim was to study the effect of gender and age on the peak GH response in the GHRH+arg test

Read the detailed description

Adult growth hormone deficiency (AGHD) is a clinical entity including increased abdominal fat mass, decreased muscle mass, low bone density and adverse effects on quality of life and cardiovascular morbidity. These signs are nonspecific, and accurate diagnosis with laboratory tests in needed.

The GHRH+arg test is used to diagnose AGHD, but the cut-off values vary based on controls used. At moment consensus cut-off criteria are BMI specific, but gender and age may also affect the GH response in the GHRH+arg.

Being tested
GHRH plus arginine test

    Measured: one year

  2. Basal serum GH (ug/l) by Immulite 2000 Xpi

    Measured: one year

Questions about this trial

What is this clinical trial studying?

A study testing GHRH plus arginine test in people with Growth Hormone Deficiency, run by Helsinki University Central Hospital at 1 site in Finland.

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 7 inclusion and 5 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 12 Jan 2017. 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 Finland. 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?

Peak serum GH (ug/l) by Immulite 2000 Xpi (time frame: one year). 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 12 Jan 2017.
