About this study
Official title: Skeletal Health of Klinefelter Patients is Not so Bad
This study compared the bone health of KS patients who were actively monitored in our clinic by dual-energy X-ray absorptiometry (DXA) with that of a control group of healthy volunteers.
Read the detailed description
Klinefelter syndrome (KS) is the most common chromosome number abnormality of men, occurring in 1/500 to 1/1000 live births . It was first described in 1942 as an endocrine disorder characterised by small, hard testicles androgen deficiency, gynaecomastia and increased follicle stimulating hormone (FSH). Osteoporosis is a progressive bone remodelling disorder in which bone loss exceeds bone formation. The resulting micro-architectural defects and bone fragility are associated with increased fracture risk and mortality. In KS, testosterone deficiency is associated with decreased bone mass and low bone mineral density (BMD) , and a positive correlation of total serum testosterone and BMD has been reported . There are some exceptions ; however, most studies have reported that KS increases the risk of osteopenia and osteoporosis compared with age-matched control groups.

Questions about this trial
What is this clinical trial studying?
A study testing dual-energy X-ray absorptiometry in people with Osteoporosis, run by TC Erciyes University at 1 site in Turkey (Türkiye).
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 1 inclusion and 2 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 15 Oct 2018. 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 Turkey (Türkiye). 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?
BMD (time frame: T score obtained from dual-energy X-ray absorptiometry through study completion, an average of 2 years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03704987, which also lists 12 linked publications.
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 15 Oct 2018.
